Add:
Support for Edge in the preview browser list. Edge is only available on Windows 10+, but if you have it you can use this option to preview with the new Microsoft Edge browser.
System action 'Set minimum framerate'. Below the minimum framerate, dt (delta-time) does not get larger, causing the game to go in to slow-motion rather than keeping up the same real-world speed. This was formerly fixed at 10 FPS. The new default has now also changed to 30 FPS, to help mitigate skipped collisions at low framerates.
Change:
C2 splash loader: in preview mode if loading finishes in less than 500ms, it instantly starts the game to avoid getting in the way during development. (Note after export it still displays for a minimum amount of time.)
Loader layouts can now display in preview mode. (Previously they only ever showed after exporting)
User Media object: brought up to date with the latest spec, and it now also works with the new user media support in Microsoft Edge.
asm.js Physics: now does not step the physics world when the timescale is 0. This should avoid any issues arising from repeatedly stepping the physics world with a zero time step.
Bug Fix:
C2 splash loader: would get stuck if project did not use any images
Video: could not play in Microsoft Edge in WebGL mode
Keyboard plugin & behaviors: all keyboard input is assumed to be released when the window loses focus, including triggering "On key up" events. This is to prevent the game state getting stuck thinking keys are down if a key is released after unfocusing the window (where the browser won't receive the key up event).
Possible Javascript error using index expression with instance variable
Pathfinding: 'compare speed' did not always work when the object was not moving
Event sheet view: using the keyboard shortcut 'V' with an existing variable selected now inserts the new variable to the correct place
Loading a savegame could unpin a Pin behavior on an object with the No Save behavior
Closing a project could leave project properties showing (and would crash if any were changed)

New in Construct 2 R185 Beta (Oct 21, 2014)

Add:
Google Play: experimental support for PhoneGap/Crosswalk
Export to PhoneGap options dialog now includes Android 5.0 as a new minimum Android OS version, and it is the new default (since it has WebGL, Web Audio + WebRTC support and auto-updates the web view)
Browser: new 'ConnectionType' expression, which can return e.g. "wifi", "cellular" if known (else "unknown"). Currently supported on Chrome and Firefox for Android.
The Android/Crosswalk and PhoneGap exporters now generate a 'intelxdk.config.additions.xml' file listing the used cordova plugins, which should allow XDK builds to automatically include the right plugins.
AdMob: new 'On banner ad received' trigger
Change:
Function: 'Call function' action now provides a dropdown list with all the function names used in the project.
Exported spritesheets now pad with the last row of pixels from the image instead of with transparency, to help avoid seams appearing after export.
Updated orientation locking code to latest specification, which now also means Chrome 38+ is supported. Note for orientation lock to take effect you normally have to request fullscreen with the Browser object, which itself can only be done in a user input trigger (such as 'on touched object').
Video: worked around a bug in Chrome for Android that prevented video rendering in WebGL mode. Now Chrome for Android uses the same workaround iOS does: it floats the video element above the canvas instead of rendering it inside the canvas. This means nothing can layer above the video nor can blend mode/effects be applied to the video, but at least it can play.
Audio: removed a workaround to an old Firefox audio bug (now fixed) that could cause distorted music playback. As a result Firefox can now also apply audio effects to music, like Chrome can.
Browser: deprecated connection 'Is metered' condition: there is no longer any standard that specifies a way to detect this, so only non-standard support is left and that is likely to be removed in the near future
Browser: now compliant with latest spec for battery and connection related features, which works with Chrome 38+
Tilemap bar: now can switch the editing tilemap instance by clicking tilemap objects in the Project or Object bars.
Updated jQuery from v2.0.0 to v2.1.1
Bug Fix:
Browser: Javascript error using 'Bandwidth' expression on unsupported platforms.
Tilemap: when using non-power-of-two tile sizes, the display quality may now be better when using 'Seamless' mode.
Multiplayer: caused Javascript error on IE9.
Renaming a layer to a global layer's name did not always make it overridden.
Duplicating a layout could cause global layers to reset their properties.

New in Construct 2 R183 Beta (Oct 4, 2014)

Add:
Audio: new 'Play in background' property. Setting to 'Yes' allows audio to keep playing after switching tab/app for things like music player apps. PhoneGap export: can now choose minimum iOS and Android versions required by the app. Currently it defaults to iOS 8+ minimum since performance is significantly better, and when Android L is out it will likely become the default minimum for PhoneGap as well. However you can opt in to supporting older versions if you wish, and for Android we still recommend using Crosswalk for better support on Android 4.0-4.4.
Change:
The WebGL renderer name is now logged to the browser console on preview if it's available, e.g. "ANGLE (NVIDIA GeForce GTX 660 Direct3D11 vs_5_0 ps_5_0)". This could be useful to identify the GPU in use in dual-GPU systems, and also sometimes indicates the underlying rendering API in use (e.g. Direct3D 11 in the given example).
The Crosswalk export should now also be buildable on other XDK targets like iOS with similar support to PhoneGap (since the XDK supports Cordova). This allows the XDK to be used as an alternative to PhoneGap Build.
PhoneGap export now references cordova.js instead of phonegap.js for better compatibility with XDK and PhoneGap CLI
Dictionary: display text for 'compare current value' was incorrect
Browser object: in PhoneGap, 'Open URL' and 'Open URL in new window' now both launch the system browser.
Moved event/group expanded/collapsed state to the event sheet uistate file. This should prevent needing to merge changed "collapsed" attributes in event sheet XML when using source control.
Moved project bar item expanded/collapsed states to the project uistate file. This should prevent needing to merge changed "expanded" attributes in the main .caproj XML when using source control.
Bug Fix:
Possible check failure duplicating layouts with global layers
More cases of being able to modify layers overridden by global layers where it shouldn't have been allowed
Display would sometimes fail to restore after a WebGL context lost event. The runtime should now correctly recover.
'Soft light' WebGL shader did not work in IE11
Sprite: loading image from a URL could in some cases degrade the image quality
SDK:
"cordova-plugins" in plugin settings can now also optionally specify a plugin version after an @, e.g. "[email protected]"

New in Construct 2 R182 Beta (Sep 27, 2014)

New in Construct 2 R181 (Sep 24, 2014)

Add: Pathfinding behavior: actions to regenerate just a portion of the obstacle map, either by layout co-ordinates or by passing an object (and it will regenerate the area around the bounding boxes of all the picked instances). This can be used to do small, fast updates of the obstacle map instead of having to regenerate the whole map every time it changes, which can be slow for large maps. Note as with regenerating the full map, the update completes next tick.
Add: System expressions 'OriginalWindowWidth' and 'OriginalWindowHeight', returning the original 'Window Width' and 'Window Height' project properties.
Add: Node-webkit exporter: new options upon exporting to set single instance, window frame, resizable and kiosk modes
Add: Multiplayer: new 'Kick peer' action, to forcibly remove another peer when host
Change: Node-webkit: updated to v0.10.3, and updated the Windows version to a special build which appears to include a fix for the occasional freezing bug. (Thanks to Roger Wang for investigating and providing the fix.)
Change: The (built-in) CocoonJS plugin and CocoonJS exporter are now deprecated and are hidden from the editor by default.
Change: Setting 'Preview effects' to 'No' in project properties now also displays all object with a 'normal' blend mode in addition to rendering without shader effects.
Change: Audio preloading is now disabled for the Android stock browser (but not Chrome for Android), because in some versions it does not appear to be able to correctly indicate whether audio has loaded, and could hang on the loading bar. This probably makes little difference to audio playback, since the Android browser can only play one sound at a time and only in a user-input event, making it hard to play sound effects.
Change: Audio: 'all preloads complete' condition now is only true after the audio has also been decoded. Previously it was true if the audio had only downloaded but not finished decoding. This guarantees that metadata like the sound duration is available when 'all preloads complete'.
Bug Fix: Video: Javascript error trying to load a blocked video from a cross-domain source. This still does not work (the security model of the web does not allow this unless the server sends the Access-Control-Allow-Origin HTTP header) but logs the error to the console instead of popping up an alert.
Bug Fix: Layer background color did not always fill correctly in layout view
Bug Fix: Changing layouts could rearrange relative Z order of global objects
Bug Fix: Pixel rounding mode could in some cases round the wrong way and offset objects by 1px
Bug Fix: Encoded some files in UTF-8 with BOM to help pass Windows Store certification
Bug Fix: Objects both in a container and with the 'Persist' behavior were sometimes not persisted correctly
Bug Fix: Audio: 'all preloads complete' could never become true in some cases in Firefox
Performance: Audio: reduced memory usage when using large numbers of sound effects with preloading

New in Construct 2 R175 (Jul 11, 2014)

Add:
Images and animation frames now have an original source path which the image/animation can be reloaded from
Add:
New project property: Preload sounds
Add:
Touch: new 'On tap object', 'On double-tap object' and 'On hold over object' triggers
Add:
Animation editor: new option to "replace entire existing animation" when importing a sprite strip
Add:
Animation editor: option to 'Copy previous collision poly' when right-clicking an animation frame. This should make it easier to design an animation with a gradually changing collision poly that matches the animation.
Change:
New icon for File Chooser plugin
Change:
Audio importer: importing audio files with the same filename now overwrites the existing files instead of creating new ones with a different name. This should make it much easier to update existing audio files.
Change:
Audio importer: no longer retains .wav files in the project. These were never used for anything nor exported for any platform.
Change:
Parameters dialog: expression field now has a maximum height of 300px, to prevent overflow when pasting in long strings. We still strongly recommend you do not paste in large amounts of data - use project files instead.
Change:
Image editor: importing an image now only guesses the collision polygon if the current poly is a default bounding box.
Bug Fix:
Debugger: long values without spaces should now wrap inside the value cell instead of extending off to the right
Bug Fix:
Image deduplication on export did not always remove duplicate images within the same object, only between different object types. It should now correctly deduplicate identical images within the same object or animation.
Bug Fix:
Platform behavior: another tweak to avoid snapping to platforms at the top of jumps
Bug Fix:
Multiplayer: should now be able to join another room in 'On signalling left room'
Bug Fix:
Twitter plugin: possible Javascript error using 'Reload' action
SDK:
The Function object now adds a global Javascript function that can be used to trigger a function in the event system. Call c2_callFunction("name"); to call function "name", and optionally add parameters in an array, e.g. c2_callFunction("name", ["param1", "param2"]);. Parameters can only be strings or numbers. It also returns the value returned from the event system. Check the function exists before using it since projects which do not use the Function object will not have that global function.

New in Construct 2 R174 (Jun 26, 2014)

Add:
New 'File chooser' plugin. Allows access to local files on the user's system. (Icon is wrong in this build, new icon will come in future release)
Add:
Touch object: new triggers 'On hold', 'On tap' and 'On double tap'. These make it easy to detect these gestures in a multitouch-aware way
Add:
Project property: 'Preview effects'. Allows rendering of shader effects in the editor to be enabled and disabled without having to change the WebGL setting
Change:
Preview server: now explicitly disables caching. This is a speculative fix for sporadic problems with incorrect previews
Change:
PhoneGap export: for Android now specifies the target SDK as 19 (KitKat). This hides the legacy menu button. On older devices the Browser object 'On menu button' should still trigger if the system shows the button or has a hardware button, but don't rely on Android having a menu button; use an in-game button instead
Change:
PhoneGap export: can now select new permissions (camera, vibrate) as well as optionally turn off the Media permission. Media is used to enable PhoneGap audio playback in case the web view is not able to play sound
Change:
Browser object: now wraps the 'eval' call in the 'Execute Javascript' action and 'ExecJS' expression with a try/catch statement, and if it catches logs an error to the browser console. This should help prevent mis-use of javascript execution crashing the entire game
Change:
Updated to the latest node-webkit 0.10.0-rc1, based on Chromium 35. This should mean node-webkit's WebRTC is now compatible with Chrome so the Multiplayer object can interoperate. We're already aware of some node-webkit bugs in this update; we will be keeping it up-to-date over the next few betas and hopefully this will be resolved by the time the finished node-webkit update is available
Change:
Intel AGI export is now deprecated and no longer supported or maintained. We recommend exporting with Ejecta on iOS (and PhoneGap from iOS 8+) and Crosswalk for Android. If you still need to use this exporter for older projects, right-click in the Export Project dialog and click 'Show deprecated exporters'
Change:
As with the Intel AGI export, the Intel AGI plugin is now also deprecated. If you still need to use it, right-click a space in the 'Insert object' dialog and click 'Show deprecated plugins'
Bug Fix:
PhoneGap: app would crash using Audio object running on Android without the Media permission enabled. A future version of Android should enable the Web Audio API in the web view, allowing it to play back audio without needing the Media permission
Bug Fix:
PhoneGap: on iOS, fixed issue with objects not properly destroying due to a missing Javascript feature. We previously fixed this for the Safari browser, but this also fixes it for the web view
Bug Fix:
Letterbox integer scale now determines the integer scale based on device pixels, not CSS pixels. This should provide better results especially when running on devices with non-integer device pixel ratios. This should also resolve rounding errors causing some devices to show any letterbox mode 1-2 pixels off the correct size
Bug Fix:
Editor crash typing 1%0 in an expression
Bug Fix:
Twitter plugin: issues having more than one button in a layout
Bug Fix:
HTML5 export with ad bar template may have displayed incorrectly on iOS Safari

New in Construct 2 R171 (Jun 6, 2014)

New in Construct 2 R170 (May 23, 2014)

Feature:
New real-time shadow casting engine, with new Shadow Light plugin and Shadow Caster behavior
Add:
Three new shadow examples: shadow colors, shadow light height, shadow soft penumbras
Add:
Tilemap: new experimental 'seamless mode'
Add:
New interpolation system expressions: qarp (quadratic interpolation through 3 points), cubic (cubic interpolation through 4 points), and cosp (cosine interpolation)
Add:
New experimental option in Preferences dialog: 'Cache icons in editor for better performance'. Defaults to on (which is what it used to do). If turned off, it can reduce editor performance since every time an icon is needed it will have to re-load the object image and resize it down to an icon. Icon quality is also reduced to help make this as fast as possible, but this mode has the benefit of helping to avoid hitting a limitation in Windows of how many icons an application can create, which can cause stability issues with very large projects.
Change:
Reverted Closure Compiler to the earlier version. r169 updated it but it turns out the latest version requires an update to Java which causes compatibility problems, so we're sticking to the old version for now.
Change:
In preview mode 'assert failure' and 'javascript error' dialogs now show at most once per run. Later assert failures or JS errors are logged to the console. This is because any alerts after the first one are almost always directly caused by the first one. Often users try to report all the errors in a bug report when only the first dialog was useful, so it should help simplify bug reports (and make SDK development less annoying if you end up clicking through lots of those dialogs).
Bug Fix:
Sprites could appear at the wrong size after export
Bug Fix:
Several fixes to editor UI layout on high-DPI displays
Bug Fix:
Twitter plugin: error using 'restart layout'
Bug Fix:
Multiplayer: error passing invalid index to room list expressions
Bug Fix:
IAP plugin javascript error when used in Windows Store apps
Bug Fix:
Adding new Text objects sometimes did not preserve the hotspot position properly
Bug Fix:
Debugger sometimes indicated incorrect Pathfinding behavior speed
Bug Fix:
Tiled Background with WebGL shader on high-DPI device with WebGL support could display incorrectly
Bug Fix:
Pathfinding behavior didn't work on Windows Phone when exported as universal app

New in Construct 2 R169 (May 9, 2014)

Feature:
Google Play plugin to handle login, leaderboards and achievements for Google Play Game Services
Feature:
Twitter plugin, allowing an in-game tweet, follow or mention button
Add:
Multiplayer: can now list rooms in a game instance, making it possible to design a lobby where you can pick from a list of active games
Add:
IAP plugin: experimental support for Chrome Web Store purchases using Google Wallet. Let us know if it works for you.
Add:
New project property for 'Downscaling' quality
Add:
AJAX: new 'method' parameter in 'Post' action, so you can specify other methods like PUT, DELETE, etc.
Add:
AJAX: new 'Set request header' action to customise HTTP headers sent with the next request
Add:
Anchor behavior: new 'None' setting for anchoring to window left or window top
Change:
Updated the Spriter importer, with changes aimed at supporting character maps and collision boxes, and also now offers to import any audio files used in the animation. Note that the Spriter plugin will need to be updated to sync up with these changes. Also the Spriter editor has already been updated to work with some of the changes; re-download it from Brashmonkey to get the latest version.
Change:
Renamed 'Intel XDK' plugin to 'Intel AGI', since that's all it works for and some people thought it worked in Crosswalk where it has no effect.
Change:
Updated Closure Compiler (used for minifying on export) to the latest version
Change:
Updated PNGCrush (used for image recompression on export) to the latest version
Bug Fix:
Possible Javascript error using 'Is overlapping' in a sub-event to 'On collision'
Bug Fix:
Browser object's 'Open URL in new window' should now work correctly in Crosswalk
Bug Fix:
Pressing enter while a progress bar dialog was showing could cause it to disappear
Bug Fix:
Possible crash trying to edit Sprite animations with no layout tab open
Bug Fix:
Workaround a Safari on iPad bug where scrolling goes crazy while typing in to a textbox
Bug Fix:
Workaround a bug in Chrome and Firefox when using very large particle sizes in WebGL mode
Bug Fix:
Windows Store universal apps now also export the about, privacy, support and WindowsStoreProxy files which were missing from the desktop version of the universal app
Bug Fix:
Possible issue with Chrome being able to slightly scroll the view in scale inner, scale outer or crop fullscreen modes

Feature:
Multiplayer engine. Currently only available with a license.
Add:
New example: Multiplayer - chat room (see the walkthrough tutorial for a detailed explanation of this)
Add:
New example: Multiplayer - real-time game
Add:
Text box: 'Scroll to bottom' action (useful for textareas)
Add:
Event sheet view: new 'Screenshot selection' option (or press F8). Copies to the clipboard an image with the selected events correctly cropped. Useful for creating tutorials.
Change:
Node-webkit: updated to version 0.9.2
Change:
Node-webkit: we have decided to try disabling the GPU blacklist for the Windows builds only, due to Google's decision to always blacklist GPU acceleration on XP and Vista. Consequently node-webkit will always use hardware-accelerated WebGL on Windows. This will make some systems with buggy drivers susceptible to glitches or crashes since they would previously have got a slower but working software renderer, but we think this may be a better result than no GPU acceleration on XP or Vista at all. Note the GPU blacklist is still in effect on Mac and Linux. We're interested on feedback on this.
Change:
If there is an error loading an image (so the progress bar turns red), the error is now logged to the browser console
Change:
System 'Pick by comparison' can now also accept strings
Change:
Event sheet view: 'Escape' no longer scrolls to top if no search term entered
Change:
Event sheet view: adding a sub-event to an empty group now always expands the group so you can see what you added
Change:
On the Windows 8 Store, it appears in production 'On successful purchase' could fire with 'Has product' still returning false for that product. Now both the Windows 8 plugin and IAP plugin internally check 'Has product' before firing 'On successful purchase'; otherwise it will fire 'On failed purchase'.
Change:
Windows 8, Windows Phone 8, Crosswalk, BB10, PhoneGap and Tizen exporters: all still had the offline cache enabled, which is redundant when these are offline exporters anyway. The offline cache has now been removed for these platforms, which may improve loading times.
Change:
List: no longer adds an empty item on startup if the 'Items' property is empty
Change:
IAP object: now appears in the Free edition, but will prompt to purchase a license if you insert it
Bug Fix:
Image editor: possible crash after pasting image, unselecting then cropping
Bug Fix:
Event sheet view: possible crash undoing after 'Replace object'
Bug Fix:
Platform behavior: possible crash saving game state while overlapping a jumpthru
Bug Fix:
Workaround for yet another Safari on iPhone orientation bug when switching in to landscape on iOS 7.1. However the new minimal-ui state in iOS 7.1 makes iPhone games much more playable, with a larger usable area of the screen.
Bug Fix:
Sometimes closing the image/animations editor with Alt+F4 would preview the project
Bug Fix:
Mouse or Touch object with 'Use mouse input' could block form controls from unfocusing
Bug Fix:
Shaders which use highp precision should now work on devices without highp support by falling back to mediump precision (note: third party shaders are not updated; see the preprocessor code we use to define highmedp at the top of the CGA effect for an example)
Bug Fix:
Turret behavior: 'Acquire target' now can target any instance from the given object, not just the first
Bug Fix:
Windows Phone 8: AJAX now uses the non-standard ActiveX-based XMLHTTP, which can successfully request local project files. (All other platforms still use the standard-compliant XMLHttpRequest)
Bug Fix:
Browser: 'Invoke download' did not work after exporting with minification
Bug Fix:
Sprite: animations could fail to load in the editor after a particular sequence of saving and renaming an animation
Performance:
Event system now evaluates parameters more efficiently when dealing with multiple instances

Add:
Node-webkit plugin: 'Open browser' action (for opening a URL)
Add:
System 'is on platform' condition: new options to test for Crosswalk and Amazon web app platforms
Add:
Sprite: 'Compare animation speed' condition. Can also be used to tell if the animation is playing backwards by testing if the animation speed is less than 0.
Change:
Breaking change: Sprite 'AnimationSpeed' expression always used to return a positive value. For consistency with the 'Set animation speed' action, it now returns a negative value when the animation is playing backwards, e.g. with ping-pong animations.
Change:
System 'Set canvas size' action now effectively changes the project 'Window size' property in fullscreen games. (Previously it was only intended for use in non-fullscreen games.) Amongst other things, this also makes it possible to control at runtime the pre-stretch render size when using low quality fullscreen mode.
Change:
Crosswalk/Android: now skips exporting all .m4a sound/music files since it can use the .ogg versions. This should help keep the overall file size down.
Change:
Crosswalk/Android: now supports Browser object's 'On back button', 'On menu button', 'On search button' and 'Close' action to exit the app. Note a bug in Crosswalk means it sometimes crashes when closing with this action; Intel are already aware and hopefully will be able to fix that soon.
Change:
Crosswalk/Android: now hides the splash screen as soon as the game has loaded (or when the loader layout is ready to run).
Change:
Crosswalk/Android: when previewing over Wifi, Crosswalk-specific features like the new back button detection should now also work. (Latest Crosswalk version only - needs 'crosswalk' in user agent string)
Change:
Exported HTML5 website projects now always warn if you try to run them from disk (on the file:/// protocol), since this does not work.
Bug Fix:
Physics: possible errors caused by recreating bodies with joints
Bug Fix:
Possible javascript error trying to play music as a positioned sound in Firefox
Bug Fix:
Moving objects far away could fail to register 'On collision' events in r155
Bug Fix:
System 'is on platform' did not detect some platforms like node-webkit properly
Performance:
Turret behavior: now uses collision cells for finding targets, which should make range detection in very large layouts faster.

Add:
Tilemap: support for per-tile collision polygons
Add:
Tilemap: support for rotated and flipped tiles
Add:
Z order bar: now clicking tilemap instances sets the tilemap bar to edit that instance, and tilemaps can be edited even when they overlap other tilemaps without accidentally selecting the other instance. This should provide a more convenient way to edit multi-layered tilemaps.
Add:
New examples: Microphone input, Vibrate
Add:
A new 'Office 2010 Silver' color theme now ships with Construct 2, available in the Colors tab of Preferences
Add:
New common expression 'AsJSON' and common action 'Set from JSON'. These allow you to take advantage of the savegame system to save and load individual instance states without having to save or load the entire game, as well as other useful things like setting one object's state to another's.
Add:
Keyboard shortcuts: press 1-4 to switch tilemap editing tool
Add:
Browser object: 'Invoke download of string' action. Basically the same as 'Invoke download' but automatically creates the data URI to download with the string data. Useful for making it simpler to download JSON strings as files.
Change:
Exported HTML files no longer specify 'target-densitydpi=device-dpi' in the meta viewport tag, since it is deprecated. Instead the 'width=device-width' directive is used.
Change:
After further experimentation with the half framerate mode, it does not seem feasible to implement in a useful way in the context of a browser (it just makes choppy framerates worse, not better). We know there was demand for the feature but it does not seem possible to implement well in a browser-based environment, so the feature has been removed.
Change:
Pathfinding behavior: default cell border is now -1 so it works like you would expect it to in grid/tile-based games
Bug Fix:
Worked around broken music playback in the latest version of Firefox (due to a Web Audio API bug). Note this means audio effects cannot be applied to music in Firefox for the time being, but hopefully we'll be able to remove the workaround soon when Mozilla fix the bug.
Bug Fix:
Tilemap bar: can now still edit tilemaps when the bar is in auto-hide mode
Bug Fix:
Tilemap: hang using negative spacing values
Bug Fix:
False positive check failure using certain combinations of shaders
Bug Fix:
IE11 could still register clicks as touches even when 'Use mouse input' was disabled
Bug Fix:
Pathfinding behavior: 'set diagonals enabled' on start of layout could cause Javascript error

New in Construct 2 R150 (Nov 13, 2013)

Add
Tilemap plugin: new conditions, actions and expressions covering setting and erasing tiles at runtime, saving/loading tiles as JSON data, and converting positions to/from tile indices
Add
Tilemap bar: can now export current tilemap as a TMX. Note because Construct 2 and Tiled do not support the same features, importing then exporting will lose some information such as terrain definitions.
Add
Tilemap bar: now shows tile number for the tile under the mouse (useful with the new actions to set tiles)
Add
Tilemap editor: can now right-click to erase tiles
Add
When opening a project with missing files, the editor now prompts and lists all the missing files with a warning. Previously this only resulted in check failures in beta releases, and possibly no error message at all in stable releases.
Add
System action: set half framerate mode. (I caved!) This is an experimental option. It's basically hard-coded to skip frames when the delta-time is under 29ms, basically a magic value found by hand - this will probably also cause incorrect frame skipping on displays with refresh rates above about 70 Hz. Also due to the way browsers synchronise with v-sync, this may still look choppy even when half framerate mode is on. Let us know how it works for you.
Change
Safari iOS and Chrome for Android: will no longer play music on next touch if the music is stopped or paused before the next touch
Change
Open web app exporter: now specifies fullscreen setting in manifest as a string, since that's what Firefox Marketplace seems to want
Change
Autosave now saves a .capx.autosave file instead of .autosave.capx, so autosave files don't show in the Open dialog by default.
Change
Autosave is now enabled by default on a 20 minute interval. Please remain vigilant of any issues that may occur with autosaves.
Change
'Translucent inactive layers' setting now also locks all but the active layer, allowing for convenient single-layer editing.
Change
SCML import: now sets imported sprite's initial visibility to 'invisible', so they do not appear in the wrong place while the SCML is still loading.
Change
AJAX: now interprets a response HTTP status code of 0 as success, since some platforms seem to report it as such.
Bug Fix
Tizen: worked around a Tizen bug that would cause incorrect display when locking orientation
Bug Fix
Debugger: now counts collision and poly checks for tilemap collisions
Bug Fix
Touch co-ordinates could be incorrect in non-fullscreen high-DPI games
Bug Fix
Audio: javascript error loading a savegame with muted audio
Bug Fix
Tilemap: crash setting zero tile width/height
Bug Fix
Tilemap: collisions now work with Pathfinding and Line-of-sight behaviors
Bug Fix
Tilemap: sometimes did not update when switching between layouts
Bug Fix
AJAX: now sets LastData even when the server responds with an error
SDK
New quadTexUV function in WebGL renderer for plugins to use for distortion effects

New in Construct 2 R149 (Nov 6, 2013)

Feature:
New Tilemap plugin with integrated tilemap editor and support for importing TMX maps
Feature:
Autosave (currently off by default, enable in preferences)
Add:
Ribbon 'View' tab: new 'Translucent inactive layers' option. Makes all layers apart from the active one at 33% opacity, so the active layer is more clearly visible.
Add:
SpriteFont: set horizontal/vertical alignment actions
Add:
Scroll To behavior: can now be enabled/disabled
Add:
Project 'Orientations' property is now used to set orientations for Windows 8/8.1 apps
Change:
Attempted workaround for crash on exit issue - let us know if this is fixed or still a problem
Change:
Windows 8.1 export now generates a solution file (.sln) that opens with VS2013. Previously the .sln file would have still opened with VS2012 if it was installed, which does not support Windows 8.1 apps.
Change:
Adjusted dimmer window (that darkens editor while dialogs are up) to take up more of the application title bar, avoiding cutting off the ribbon gradient half way with the Office 2010 themes
Change:
Phonegap export: now no longer exports gap:platform tags in config.xml. This should enable the default of building for every platform Phonegap Build supports, which is more future-proof (and now includes Windows Phone 8).
Change:
Browser object: 'On back button' should now fire with PhoneGap on Android and Windows Phone 8
Change:
Windows 8 object: deprecated support for 'On view state changed', 'Compare view state' and 'Try unsnap', because support for them has been removed in Windows 8.1. Existing projects can continue to use these (despite the fact they don't work on Windows 8.1), but they cannot be used in new projects. We recommend using the Browser object's 'On resized' event and window size detection to re-implement any snapped behavior that you want (note that Windows 8.1 allows variable sized snapping).
Change:
Audio: changed the workaround for playing music on iOS Safari and Chrome for Android. Previously these would play music with the Web Audio API, but for long music tracks that could result in 20sec+ delay while it decoded the entire music track in one go. Now it uses HTML5 audio again and can start playing quickly since it streams, but it has to queue up music playback to begin in the next touch event, since the browsers only support starting HTML5 audio playback on input events (despite the fact the Web Audio API can play back at any time!). This also enables playback of music only (but not sound effects) in the Android stock browser after a touch event. Also removed unintentional use of the workaround on Firefox for Android and Tizen, which don't have the limitation.
Bug Fix:
Collisions between objects on different layers may have been mis-aligned in some cases
Bug Fix:
Worked around possible case of some objects going blank in WebGL mode in IE11 or Windows 8.1 apps due to an apparent bug in IE's WebGL implementation.
Bug Fix:
Possible crash exporting with PNG recompression disabled
Bug Fix:
Touch object: 'Is touching object' did not always work correctly with containers
Bug Fix:
Node-webkit: maximize/unmaximize actions did not always work
Bug Fix:
Event sheet view: holding shift to select a range of events did not always select sub-events of the last event
Bug Fix:
Windows 8.1 'About', 'Support' and 'Privacy policy' settings charms did not work
Bug Fix:
Audio: could still play if set silent mode while sounds still loading

New in Construct 2 R148 (Oct 22, 2013)

Change: Updated UI library to significantly newer version. New themes are supported, and the default theme is now Office 2010 Silver. Hopefully this may resolve other UI library related issues, but since it's a big update there may be quirks or new issues introduced.
Change: High-DPI support (aka retina display) is now supported on non-iOS devices. This includes Android, BlackBerry 10, Tizen and Amazon devices. Display quality is now significantly improved on these devices, but note using the high-DPI display can reduce performance.
Change: Project property 'Use iOS retina display' replaced with 'Use high-DPI display' since it now applies to non-iOS devices; options are now simply yes/no and defaults to yes
Change: High-DPI support now works in non-fullscreen or 'Crop' scale mode games. Previously these always used low-DPI display even on high-DPI devices.
Change: Browser object: 'Close' action now works on Tizen
Change: Updated the editor compiler to Visual Studio 2013 (was previously VS2010). Hopefully the new compiler is more reliable since we've had at least two crash bugs caused by the VS2010 optimizer.
Change: Exporting to Windows 8.1 now requires Visual Studio 2013 RTM. The RC version is no longer supported.
Bug Fix: Text object: 'Line height' property handled high-DPI displays incorrectly
Bug Fix: System action 'Set canvas size' was broken in r147
Bug Fix: Possible Javascript error using positioned sounds in Firefox's new Web Audio API
Bug Fix: Spurious assert failure using WebGL layer effects
Bug Fix: WebSocket plugin: could send spurious Sec-Websocket-Protocol header even with no subprotocol specified
Bug Fix: Browser object: on Tizen, using 'On back button pressed' in an OR block would not override the default behavior of closing the app
Bug Fix: Possible assert failure with certain combinations of shader effects
Bug Fix: Audio: error using save/load after changing filter effect frequency parameter
Bug Fix: Image editor: color picker layout could become corrupt after switching tools
Performance: Some optimizations to the collision detection engine

New in Construct 2 R147 (Oct 11, 2013)

Feature:
Support for exporting Windows 8.1 apps using Visual Studio 2013 Express Preview. Windows 8.1 apps use the IE11 engine, which also supports WebGL (!). There is a new dialog when choosing the Windows 8 export option, allowing you to target either Windows 8.0 (using VS2012) or Windows 8.1 (using VS2013 preview).
Add:
Support for Chrome for Android 31+'s new 'Add to home screen' feature. Like iOS, this allows you to add a web game to the home screen, showing an icon like a native app. When opened it runs in true fullscreen (no browser address bar/tabs appear).
Add:
A new 256x256 icon size. This is mainly used for the 'Add to home screen' feature on Chrome for Android and iOS Safari.
Add:
Two new color themes now bundled with Construct 2: 'Windows 7' and 'Visual Studio 2005'. You can try these out by setting them in the Preferences dialog. The default theme has not been changed, but we are open to changing the default if one theme is particularly popular - let us know what you think!
Add:
New 'Orientations' project property. This will try to be enforced automatically in a browser where supported, even without using the Browser object. On some browsers you must request fullscreen mode before any orientation lock takes effect. Note if you do use the Browser object's lock/unlock orientation actions, the runtime will stop trying to automatically set the orientation to the project setting, letting you override it. Also all export options for setting orientation have been removed, and will take their setting from this property instead. The Tizen exporter also now writes this orientation setting to config.xml.
Add:
Export dialog: now links to how to export to Tizen tutorial
Change:
Browser object: 'request fullscreen' should now always center the canvas on the screen. Previously in Firefox and IE11 the canvas would be left-aligned.
Change:
Removed project property 'Hide address bar'. This no longer appears to work on any platform; we recommend using the Browser object's 'Request fullscreen' action instead, which at least works in Chrome for Android.
Change:
Changes to Tizen's config.xml to fix some cases where the file could fail validation
Change:
Re-enabled music streaming on node-webkit to fix some backwards compatibility issues where projects assumed music started playing quickly. Note this may regress a bug where sounds sometimes do not play in preview mode, but the issue should not occur after exporting.
Change:
Preferences 'Color' tab now prompts a confirmation when clicking 'Load selected theme', to provide clearer feedback that the theme has been set.
Change:
When 'Clear background' is 'No', Construct 2 now requests to create an opaque canvas (so the canvas itself does not contain an alpha channel). This can be slightly faster and save a bit of memory on some devices. Exporters where there is definitely no need for a transparent canvas (e.g. node-webkit, Windows 8 apps) now also always create an opaque canvas.
Bug Fix:
WebGL renderer: changes made to shader rendering pipeline to fix an accidental use of undefined behavior that broke some shader effects in IE11's WebGL. (Thanks to Frank Olivier & Ben Constable at Microsoft for helping track down this issue)
Bug Fix:
Exporting packaged open web apps no longer includes 'appcache_path' in the manifest, since this is not allowed for packaged apps on Firefox Marketplace
Bug Fix:
Debugger: could sometimes get stuck stepping through events in an included event sheet
Bug Fix:
Possible Javascript error saving game when Physics behavior disabled
Bug Fix:
Possible Javascript error using containers in an 'On created' trigger

New in Construct 2 R146 (Oct 3, 2013)

New in Construct 2 R145 (Sep 26, 2013)

Add:
Browser object: 'DevicePixelRatio' expression
Add:
Audio object: 'Save/load' property to set whether sound and/or music playback state is saved/loaded
Add:
8 direction behavior: 'Set vector X/Y' actions
Add:
Tiled Background: 'ImageWidth' and 'ImageHeight' expressions
Add:
Layers bar: new context menu options to show all, hide all, hide all but one; unlock all, lock all, lock all but one
Add:
Browser object: new 'On mobile back button pressed' trigger. Note this is only currently supported in Tizen web apps. If you do not use the trigger, the game will now exit when the user presses the 'Back' button. The 'On mobile menu button pressed' trigger should now also fire for Tizen web apps as well.
Add:
Export to Tizen now provides an option after export to submit to the Tizen app store via AppBackr. Note the link is not yet live; it should be working within the next few days! Free edition users are also allowed to take advantage of publishing via AppBackr only.
Add:
WebSocket plugin: new CloseCode and CloseReason expressions (only useful after 'On closed' has triggered)
Change:
New editor breakpoint icons
Change:
Node-webkit: updated to version 0.7.5
Change:
Google Closure Compiler (used for 'Minify script') updated to latest version
Change:
PNGCrush (used for image recompression) updated to version 1.7.67
Change:
Node-webkit: now plays music with the Web Audio API only, rather than HTML5 audio piped in to the Web Audio API, since the latter appears to be affected by some Chrome bugs in some cases. This means audio must be fully loaded and decoded before it starts playing, but since all the files are available locally, there's not much delay before it starts playing.
Bug Fix:
WebSocket plugin: may not have reported the error message in 'On error' in all cases
Bug Fix:
Clicking the status bar could trigger a 'Include event sheet' or 'Clear all breakpoints' prompt
Bug Fix:
Another case of OR blocks sometimes picking incorrectly
Bug Fix:
Possible jQuery error in CocoonJS preview-over-wifi

New in Construct 2 R144.2 (Sep 17, 2013)

New in Construct 2 R144 (Sep 14, 2013)

Feature: Debugger breakpoints. Support for breaking in looping events or triggers may come in future.
Add: New 'Upgrade' tab on ribbon in Free edition. Does not appear in the Steam edition nor when a license is in use. Note the icons are temporary and will be updated soon.
Add: Sprite Font: 'Set blend mode' action
Change: node-webkit: updated to 0.7.3
Change: Start page: the Twitter feed has been removed for the time being.
Change: Windows Phone 8 export: now includes the CSS "@-ms-viewport { width: device-width; }" to try and avoid misaligned rendering
Change: AJAX plugin: no longer tries to set the Content-Length header of POST requests, since this is not actually allowed by the standard
Change: Parameters dialog: now has a maximum height, to help avoid large expressions corrupting the dialog. Note you should never paste large amounts of data in to expressions; using project files is strongly recommended.
Bug Fix: Memory leak in OR blocks that could cause high CPU usage/degrading performance in r143
Bug Fix: CocoonJS: fixed a possible javascript error using CocoonJS accelerated physics. Note there are still some physics features that will cause a javascript error in CocoonJS when using accelerated physics, e.g. revolute joints. Ludei are working on this.
Bug Fix: WebSocket: Javascript error if connecting to invalid IP or address
Bug Fix: AdjustHSL/mask shaders: another case of handling alpha incorrectly when lumincance adjusted
Bug Fix: Exporting projects with a dot at the end of the name didn't work, since Windows doesn't like folder names ending with a dot. Now it removes the trailing dot if any.
Bug Fix: Event sheet view: event numbers could sometimes appear italic or bold
Bug Fix: Attempted fix for 'Edit theme' dialog not showing color picker popups on Windows XP
Bug Fix: Text object: TextHeight expression now takes in to account the line height
Performance: Form controls (Text Box, Button and List) engine CPU usage now significantly reduced, especially when using lots of controls.

New in Construct 2 R143 (Sep 4, 2013)

Feature: Debugger: new 'Watch' tab. Individual debugger properties can be added to it to create an area where you can watch just the values that interest you from a range of different objects. (Not available in free edition)
Add: Node-webkit plugin: lots of new window features, e.g. set/get window X, Y, width, height, title, enable/disable resizing/always on top, show dev tools, set and get clipboard text
Add: Browser: condition 'Is Portrait/Landscape'
Add: Browser: expressions 'ScreenWidth' and 'ScreenHeight'
Change: Audio: Chrome for Android now ships with the Web Audio API. However music did not play, because we still use HTML5 audio to play music (so it streams and starts playing more quickly), and HTML5 audio support is broken on Chrome for Android. We've applied the same workaround we use on iOS Safari: music is now fully downloaded and played via the Web Audio API. This is better than not playing music, but since it does not stream, it could take a while before music starts playing.
Change: Audio: on Chrome for Android and iOS Safari, only loads one music track in to memory at a time. Previously all music played so far would be loaded in to memory due to our workaround.
Change: Water background effect: now handles alpha differently - either fully warps the background or leaves it intact depending on if the foreground alpha is 0.
Change: Platform behavior: 'Is moving' is now false in 'On jump' when jumping from standing still. Previously it was always true, which could make it play the wrong animation.
Change: Ctrl+F4 no longer closes the current tab (conflicted with Ctrl+F4 to debug entire project)
Change: We've removed the reference to jQuery's source mapping file to prevent a console error appearing.
Bug Fix: OR blocks which were sub-events to ordinary blocks did not always pick instances correctly
Bug Fix: Object IIDs are now available immediately after creating them
Bug Fix: Mouse: 'Is over object' did not always work properly after a save/load
Bug Fix: Double-quotes in the 'About' section of project properties could break the node-webkit export
Bug Fix: AdjustHSL shader did not handle alpha correctly
Bug Fix: Timer behavior: javascript error using full state save/load

New in Construct 2 R138 (Jul 12, 2013)

Add: Gamepad: now supported on CocoonJS. This means the Gamepad object should work with Ouya controller input when CocoonJS gets Ouya support.
Add: New Node-Webkit preview mode. Choose 'Node-Webkit' from the new option in the 'Preview browser' project property. This allows testing in preview mode with all node-webkit specific functionality enabled (such as file IO). Note this only runs the Windows version (obviously), and runs node-webkit directly from the install directory so the AppFolder expression will return \exporters\html5\node-webkit\win32. If this sounds like a problem for you we recommend using a global variable, and if 'Is in preview' is true hard-code it to some development folder somewhere else, otherwise set it to NodeWebkit.AppFolder. Then use the global variable instead of the AppFolder expression.
Add: Node-webkit plugin: 'Run file' action. This can be used to both run other programs, or open files (like double-clicking a file from the OS file explorer), such as opening an image with the default system image viewer.
Add: CocoonJS plugin: new option to choose either the accelerated physics engine or the standard Javascript Box2D engine (called the web-based engine). By default it uses the accelerated engine, but you might want to switch back to the old engine in case the behavior of the game changes with the accelerated engine (or it has bugs)
Add: CocoonJS plugin: properties to alter the store managed and sandbox settings
Add: CocoonJS plugin: new 'refresh banner' and 'refresh fullscreen' ad actions
Add: CocoonJS accelerated physics: code updated to support the 'disable collisions' feature. This won't work until the next CocoonJS launcher update.
Add: Line-of-sight behavior: help link now points to its new manual entry
Add: Geolocation: help link now points to its new manual entry
Add: Bookmarks bar: help link now points to its new manual entry
Add: Sprite font: help link now points to its new manual entry
Add: Timer behavior: help link now points to its new manual entry
Add: New manual entry on Construct 2's supported platforms
Change: Node-webkit: updated to v0.6.2. Also now the Windows and Linux exports use a separate package.nw in the same folder as the executable instead of binary-appending the data to the executable itself, which should prevent occasional antivirus software false-positives for your end users as well as when actually exporting.
Change: Node-webkit: user agent string was the same as Chrome's; it is now in the form "Mozilla/5.0 (Windows NT 6.2; WOW64) AppleWebKit/537.36 (KHTML, like Gecko, Chrome, Safari) NodeWebkit/0.6.2" (notable change is it includes NodeWebkit so servers can detect it, but it should otherwise still detect as a Chrome browser)
Change: Layout view: the resize-from-center key has been changed from alt to control, to prevent it conflicting with holding alt to temporarily disable grid snapping.
Bug Fix: CocoonJS plugin: attempted fix for backwards-incompatible changes to the advertising and IAP features in the 1.4 update. However it's difficult for us to be confident it definitely will work exactly to how it used to, so please watch out for anything that is still broken.
Bug Fix: CocoonJS: accelerated physics will now work with applying forces and torque when the next CocoonJS launcher comes out
Bug Fix: Sprite font: sometimes the character at the end of a line could disappear
Bug Fix: Sprite font: 'trimRight' javascript error on IE
Bug Fix: Audio: rotating layers now rotates positioned sounds around the listener rather than around the scroll position
Bug Fix: Possible javascript error creating objects in containers (notably creating an Array when in a container with a Sprite)
Bug Fix: Layout view: sprites could disappear if shift+resized with a negative size

New in Construct 2 R137 (Jul 4, 2013)

Add: Z Order Bar: now shows instances selected in the layout view in bold, adds the instance UID after the name, and instances can be double-clicked to flash them in the layout view to help identify them.
Add: Layout view: new ribbon option to display collision polygons (and a new theme color for the lines)
Add: New advanced Real Time Strategy (RTS) game template. This is easily the most advanced template or example that comes with Construct 2, and it uses lots of tricks. It's probably going to be tough for beginners, but should be interesting to experienced users.
Add: Every behavior with a 'Set enabled' action now has an 'Initial state' property to choose if it's initially enabled or disabled
Add: Layout view: hold alt to resize objects from center
Add: System: 'Pick instances overlapping point' condition
Add: Pathfinding behavior: 'Set speed' action
Add: Timer behavior: 'Duration' expression
Add: Node-webkit plugin: 'Copy file' and 'Move file' actions, which also work with binary files
Add: Query string ?nw can now be appended to the preview URL to force the engine to detect as node-webkit. Useful for previewing quickly with node-webkit specific features.
Change: We've reverted back to not supporting letterbox mode in CocoonJS, since we can't find a reasonable way to support it within the limitations of CocoonJS for the time being.
Change: Updated to node-webkit 6.1. This has also allowed us to lift the WebStorage storage limit to 50mb, although the limit on individual keys is not changed (still about 2mb according to my tests).
Change: Pathfinding behavior: setting the object angle while moving along a path now overrides the behavior's movement angle
Change: Audio: positioned sounds now move with rotating layers
Change: CocoonJS: when exporting minified, Construct 2 now uses simple instead of advanced mode when running Closure Compiler (for CocoonJS only). This means physics is no longer broken when enabling "Minify script", but this has implications for the reverse-engineerability of the project (to the effect of making it just very hard, as opposed to extremely hard).
Bug Fix: Particles object: was broken with canvas2d renderer in r136
Bug Fix: Platform behavior: a couple of issues were introduced in r136 due to a bug fix; should be working better now
Bug Fix: Platform behavior: passing horizontally through a jump-thru while falling could stop vertical motion; should now pass through smoothly
Bug Fix: System: 'set layout scale' could sometimes end up showing areas outside the layout in bounded scrolling mode
Bug Fix: Image editor: possible hang using Fill tool
Bug Fix: Speculative fix for some users color themes going wrong after upgrading from r132
Bug Fix: Line of sight behavior: did not always work correctly with multiple instances
Bug Fix: Possible project corruption inserting a SpriteFont, immediately renaming it, then choosing file -> save as .capx
Bug Fix: Ctrl+F4 (close tab) no longer conflicts with F4 to preview project
Bug Fix: On rare occasions a "No running layout" check failure could appear at runtime, or a javascript error after export

New in Construct 2 R136 (Jun 26, 2013)

Feature: New official Sprite Font plugin
Feature: New Timer behavior
Add: System object regex features: 'Regex test' condition; expressions 'RegexSearch', 'RegexReplace', 'RegexMatchCount', 'RegexMatchAt'
Add: Added a new platform-specific 'Stride' plugin. This is for use with Stride Academy as part of our partnership with LTS Education Systems.
Add: Bookmarks bar: now includes text describing bookmarked events, e.g. "System: Start of layout" instead of just "Event"
Change: CocoonJS: we've now enabled the letterbox fullscreen modes for CocoonJS. It seems to align the display incorrectly, but we'll investigate this for the next build.
Change: The local preview server should now send the correct MIME type for .eot and .ttf font files.
Change: System: 'For' loops can now run backwards (when the end value is lower than the start value)
Change: Event bookmark icons updated
Change: Project bar: could sometimes scroll away when dragging object types to folders, should now at least keep the dropped item in view
Change: Layout view: updated editor text renderer to use Freetype 2.5. This may fix some minor bugs and improve text rendering quality, especially at small sizes.
Change: Anchor behavior: enabling the behavior when it is disabled now anchors to the object's current position. Previously it still anchored to the object's old position.
Change: Steam build: updated Steamworks API to latest version
Bug Fix: Crash pressing alt introduced in r135 (oops :P)
Bug Fix: A few theme colors didn't work properly - they should all now be correct
Bug Fix: Line of sight behavior: 'Has LOS to' did not work properly when inverted
Bug Fix: Navigating to bookmarks hidden by collapsed groups/events now expands them so the bookmark can be seen
Bug Fix: Import Audio dialog: was accidentally case sensitive on file extensions (so .WAV would not import but .wav would)
Bug Fix: Javascript error using User Media object in CocoonJS (note: the object is still not supported, but at least does not crash the app)
Bug Fix: Bug with texture management in WebGL renderer could cause sprites to go blank after export if they had deduplicated images
Bug Fix: Platform behavior: could end up shaking when running up to wall at top of slope
Bug Fix: Automatic spritesheeting on export could sometimes emit a bigger spritesheet than necessary, wasting memory.

New in Construct 2 R135 (Jun 20, 2013)

Feature
New event bookmark system; new Bookmarks bar
Add
Enhanced themeing system
Add
Audio: 'Stop all' action
Add
Physics: 'Set enabled' action. Note disabling the object removes it from the physics world entirely, so other objects can pass through it.
Add
Layout view: can now hold alt to temporarily disable grid snapping when moving objects
Add
Event sheet view: new keyboard shortcut Ctrl+F now opens ribbon to Events tab and focuses event sheet search box
Change
node-webkit: updated to version 0.6, which is based on Chromium 28
Change
For visual consistency, conditions and actions now draw identically both when they are directly selected, and when the event block containing them is selected.
Change
Layout view: direction of horizontal mouse wheel scrolling has been flipped (I don't have a horizontal scrolling mouse to check, but apparently it went in the wrong direction)
Bug Fix
Pick by highest/lowest variable didn't work with families
Bug Fix
Added a workaround for a Chrome for Android bug with touch input. This should fix a number of cases where touch input stops working properly in Chrome for Android; we've also notified Google of the problem, but the workaround should make sure it works from this build onwards.
Bug Fix
Possible javascript error sharing from a Windows 8 app after minified export
Bug Fix
Renaming families could sometimes result in an unopenable project
Bug Fix
r134's new Ctrl+Left/Right shortcuts no longer conflict with Ctrl+Shift+Left/Right for selecting text in expressions
Bug Fix
Some 'Open' dialogs would not appear on Windows XP (regression from r134). These should now appear on Windows XP, but only Windows Vista and up will remember the last folder used for each dialog individually.
Bug Fix
Export to Windows 8: project properties are now trimmed on export, so trailing spaces don't break the app manifest
Bug Fix
Event sheet view: tabs now draw correctly in comments
Bug Fix
Custom movement: 'push out solid nearest' could cause objects to move when they shouldn't have
Bug Fix
Pathfinding behavior: didn't work in CocoonJS or Intel XDK
Bug Fix
Check failure renaming a project changing only the case then saving

New in Construct 2 R134 (Jun 13, 2013)

Add: New Line-of-sight behavior; also added a new example showing basic usage
Add: New Geolocation plugin; also added a new example showing basic usage
Add:, Projects now have an 'Icons' subfolder under 'Files'. Rather than using template icons every time you export, the icons are taken from the files in the project. This allows you to draw the icons once and have them used for every export. You can now also double-click .png project files to open them with the Image Editor, so you can edit the icons using C2's editor. Note currently editing the icon files cannot be undone.
Add: User Media object: features to get the ambient light reading, if a sensor device is present and supported; added a new 'Ambient Light' example demonstrating usage. Note this is not yet widely supported - it should work in Firefox for Android and Windows 8 Apps, and further support should be coming to other browsers in future. We've been unable to verify the Windows 8 ambient light support works, but code is in place, so please test it if you have a Windows 8 device and let us know if it works.
Add: New event sheet keyboard shortcuts: Ctrl+Home (go to top of sheet), Ctrl+End (go to bottom of sheet), Ctrl+Left/Right (back/next in event wizard/parameters dialog)
Add: New layout view keyboard shortcuts: Ctrl+Shift+Up (send to front of layer), Ctrl+Shift+Down (send to back of layer), C (center horizontally in window), T (align to top of window), hold Tab and click to select instance underneath (keep clicking to cycle through the Z order under the mouse)
Add: Common condition to pick instance with lowest/highest instance variable value
Add: System conditions 'Pick by comparison' and 'Pick by evaluate'
Add: Is enabled' condition for Solid and Jumpthru behaviors
Add: Object types can now be double-clicked in the Object Bar and Project Bar to edit their image/animations
Add: Event sheet view: 'Enter' can now also edit groups
Change: The 'Open' dialogs for opening a project, importing image files, importing audio, and importing project files now all remember their last folder independently. For example, clicking 'Import image' will open at the last folder you imported an image from, regardless of whether you open projects or import audio from other folders in between.
Change: Common condition 'Pick nearest/furthest' moved to 'Size & Position' category; 'Pick by unique ID' moved to 'Misc' category
Change: Custom movement: now the 'Stop stepping' action doesn't cancel the next axis of movement if using 'Horizontal then vertical' or 'Vertical then horizontal'. For example in 'Horizontal then vertical' mode, if the horizontal step was cancelled, previously it would also skip running the vertical stepping; now it still runs the vertical step afterwards.
Change: Editor allocates icons in a more memory efficient way, which should help avoid crashes or errors with very large projects
Bug Fix: Breaking change: 'Every X seconds' used to read its parameter every tick, and run if the elapsed time had passed. Now it only reads its parameter whenever the event runs. This fixes a long-standing bug where 'Every random(1, 3) seconds' would basically run once a second; now it works as expected, but this could cause existing projects to change how frequently they run 'Every' events.
Bug Fix: 9-patch and Sprite Font plugins were broken with WebGL renderer in r133
Bug Fix: Auto font size' in form control plugins now compensates correctly for high-dpi displays
Bug Fix: Triggers no longer fire when in an event sheet included from a disabled group
Bug Fix: Another issue with false positive collisions in rare circumstances

New in Construct 2 R133 (Jun 7, 2013)

Add:
Image deduplication on export
Add:
New 'node-webkit' option for system 'Is on platform' condition
Add:
Wrap behavior: new 'Wrap to' property to optionally wrap to viewport instead of layout bounds
Add:
Three new examples for the Touch object, showing how to pan, zoom and rotate a layout based on multitouch input
Add:
New 'Flying along' template game (like the classic helicopter rising/falling game)
Add:
Users with site wide licenses can now set the registry key HideLicenseLink to 1 (as DWORD) in HKCU\Software\Scirra\Construct2 to hide the 'View license' link in the About dialog.
Add:
Pathfinding behavior: 'Set diagonals enabled' action, 'Diagonals are enabled' condition
Add:
Physics behavior: conditions 'Compare velocity', 'Compare angular velocity', 'Compare mass'
Add:
Sine behavior: new 'forwards/backwards' mode, which moves object along its angle rather than just horizontally or vertically
Add:
CocoonJS export: now exports a stub index.html file which should allow games to run via CocoonJS on real browser platforms (since CocoonJS can now also compile for a wide range of platforms other than iOS/Android which use the non-browser engine)
Add:
CocoonJS: added support for preview-over-Wifi within the CocoonJS launcher for quicker testing. Enter the preview-over-Wifi URL in the 'Zip URL' field, but this probably won't work until the next CocoonJS launcher update is made public
Change:
Construct 2 now displays the .capx filename or project name (for folder projects) in the title bar
Change:
CocoonJS export: we've worked with Ludei to fix some bugs, and subsequently have re-enabled accelerated physics in this beta. It won't work until the new CocoonJS launcher comes out. Two known issues: disabling collisions isn't supported yet, and it's still broken when minified, but we're working on both issues.
Change:
Restarting a layout now also clears all pending 'Wait' actions. They are still not cleared if changing to a different layout.
Change:
Updated Closure Compiler to latest version
Change:
The maximum spritesheet size on export has been lifted from 512 to 2048 (the largest widely supported texture size). This may make some projects slightly larger to download, but it should save more memory at runtime, which we believe is more important.
Bug Fix:
Changed WebGL renderer to use tri-linear filtering on power-of-two image sizes (for better quality when scaling down)
Bug Fix:
Node-webkit: dragging an image file to a game without the node-webkit plugin would navigate the browser frame to that image
Bug Fix:
Collisions could return a false positive in rare circumstances
Bug Fix:
Pick by UID' could pick instances that had been filtered out by previous conditions. This was a backwards incompatibility with r126 (and goes against the usual working of events); it now has been corrected and projects made in r126 should work the same again.
Bug Fix:
Construct 2 no longer places dialogs off-screen when remembering their positions; it always moves them in to the visible screen area. This should fix a long-standing bug with dialogs disappearing when switching between different monitor setups (which could be worked around by pressing 'Reset dialogs' in preferences)
Bug Fix:
Possible javascript errors using Browser object back/forward actions

New in Construct 2 R132 (May 24, 2013)

New in Construct 2 R131 (May 21, 2013)

Feature
New 'Colors' tab in Preferences. This allows you to customise the event sheet view color scheme, and save your theme to a file. Any theme files in the install directory 'Themes' subfolder will be available for loading from the Preferences dialog as well.
Add
CocoonJS object: experimental support for Game Center. Currently only supports submitting scores. We haven't been able to fully test it since it seems to only fully work with a published app and not in the CocoonJS launcher, so let us know how it works out for you. Note Game Center is only available on iOS.
Add
CocoonJS object: ability to retrieve a list of all products available for IAP, with their details such as title and localized price.
Add
CocoonJS object: ability to prompt a dialog to get text input. Useful workaround to the text box form controls not working.
Add
Project bar: right-click and "Auto-import all in folder" option. Automatically import a project file for every file that has been copied in to the project's 'Files' folder in a folder-based project. Note this only imports and does not delete files that have gone missing - you should still delete files from Construct 2 if you wish to remove them.
Add
List object: conditions 'Compare selected text', 'Compare item text at'
Add
WebStorage: conditions to compare key values, either as a text or as a number
Change
We are temporarily rolling back the Physics engine to the older, slower version on CocoonJS. The accelerated physics on CocoonJS had several bugs which broke lots of projects. We will re-enable it when Ludei have fixed the issues, and probably after the next stable release to give it a thorough test run.
Change
Another change to how iframed games handle focus - clicking or touching inside an iframed game should now always give it keyboard focus
Change
Audio file parameters are now sorted alphabetically
Change
CocoonJS: now calls finishPurchase() on completed purchases, which should resolve some IAP issues
Change
The jquery-2.0.0.min.js file now includes a UTF-8 BOM, to work around the extremely fussy WACK tool.
Bug Fix
Changing the type of an instance variable which was already referenced in events could make invalid events which crashed the editor. To avoid this, the 'Type' dropdown in the 'Edit instance variable' dialog is disabled if any events exist referencing the variable.
Bug Fix
Inverted 'Mouse is over object' condition did not always work after save/load
Bug Fix
Parameters dialog: typing a space in a string literal no longer temporarily resets the style to ordinary black text
Bug Fix
Project bar: choosing 'import files' then selecting files already in the project's 'Files' folder did not work correctly. Now it ignores files already added to the project, and automatically imports any selected files that are not in the project.
Bug Fix
Custom movement: 'On vertical step' did not trigger correctly

New in Construct 2 R130 (May 15, 2013)

Export for Tizen
Add
Fullscreen in browser 'Scale' option replaced with 'Scale inner' and 'Scale outer'. 'Scale outer' is what it used to do, but 'Scale inner' is a new variant that scales but cuts off edges of the screen rather than extends the view if the aspect ratio does not match. This is useful for designing 16:9 games that cut off the edges and only show the middle section in 4:3 displays.
Add
Sprite: initial animation property
Add
Event sheet: option to right-click a global variable and 'move to event sheet'
Add
AJAX object: in node-webkit, can now load files from disk in the same folder as the app. Use 'Request URL' and enter a name like "myfile.txt", and if it cannot be found as a project file, it will then try to load "myfile.txt" in the same folder as the app.
Add
New 'Node-Webkit' plugin, to access node-webkit specific features. Currently this plugin allows basic file operations (like reading and writing files on disk) and opening file dialogs.
Add
Browser object: actions to log to the browser console, and start/end log message groups. Useful for debugging.
Add
Browser object: action to execute a string of Javascript code, and an expression to execute javascript and return the result (if it's a number or string). These basically call eval(), which is widely regarded to be dangerous. Try to avoid using these features; while occasionally useful, the Javascript SDK is almost always a more elegant way to add custom code to Construct 2 projects.
Add
Project settings for Email, Website and ID, which are now used as defaults by several exporters. Project properties have also been re-arranged in to two separate "About" and "Settings" categories. Several export dialogs now have had their author/email/website/id fields removed and will take the values directly from project properties instead.
Add
Drag & Drop behavior: can now axis limit to just horizontal or vertical movement (via 'Axes' property)
Add
System: 'Is on platform' condition. Test if running as e.g. a Windows 8 app, in CocoonJS, as a HTML5 website, etc. Should help setting up one project to work nicely on multiple platforms by dealing with platform-specific differences.
Add
New example: detecting the input method. Shows how to make a title screen that detects if the user has keyboard/mouse or touch controls, and switches the control method accordingly.
Change
The runtime will now attempt to use WebGL in CocoonJS if it is available. Note there are not yet any public versions of CocoonJS that support WebGL yet - this is in anticipation of future support. Note releases prior to this one will never use WebGL on CocoonJS since we had previously skipped even checking for it.
Change
Z Order bar: now uses icon for sprite instance's initial frame to help differentiate instances
Change
Sprite: icon in editor now appears taking in to account the first instance's initial frame. This means if all your instances use a non-default initial animation/frame, the editor icon will correspond to that frame's image. (You might need to close and reopen the project for this to take effect after changes.)
Change
Gamepad: now implements a radial deadzone instead of axial deadzone
Change
The default 'fullscreen in browser' property is now 'Letterbox scale', since it uses the whole screen without changing the aspect ratio.
Bug Fix
Could not change the case of a layer name from the properties bar
Bug Fix
Node-webkit: tab then enter sometimes opened a "What is a browser?" page
Bug Fix
Deleting the last object type in a family did not also delete the family
Bug Fix
Pathfinding behavior: did not update obstacle map when changing layouts with a global object
Bug F
Exported Windows 8 and Windows Phone 8 projects now use the project 'Version' property

New in Construct 2 R128 (May 2, 2013)

New in Construct 2 R127 (Apr 26, 2013)

Feature:
Export to Blackberry 10
Add:
Open Web App exporter (for Firefox OS): now supports packaged apps (select 'packaged app' and zip up the resulting files). Useful if you want to host the app on the Marketplace servers instead of your own server. Tutorial will be updated soon.
Add:
Browser object: 'focus' and 'unfocus' actions should now work in node-webkit
Add:
Text: added missing 'Set blend mode' action
Add:
System: new condition 'Object UID exists'
Change:
node-webkit updated to v0.5, based on Chromium 27.
Change:
jQuery version updated to version 2.0.0. It's smaller, faster and does not support IE 6-8, which should not be a problem for Construct 2 projects since they are not supported anyway. jQuery 2 also now officially supports several platforms that Construct 2 exports to, such as Windows 8 apps, PhoneGap, Firefox OS, and more.
Change:
When dragging instances from the project or object bar, the properties are now based on an instance already in the project, rather than using the plugin defaults. (E.g. if you add a text object, make it red, then drag in another one from the project bar, the new one will also be red where previously it would be black.)
Change:
The condition 'Pick by UID' has been reimplemented to work with a single lookup, rather than iterating every instance. This should make it faster, but it also is now the one condition that is the exception to the rule about picking newly created objects in subevents, i.e. you can call a function on a newly created object, passing its UID, and successfully pick the instance, which did not previously work.
Change:
The Keyboard object now always blocks certain scrolling keys like the up and down arrows when it detects it's in a frame. Hopefully this will help fix scrolling problems on embedded games like in Kongregate or Newgrounds.
Change:
Pick by UID' is now not invertible (use 'Object UID exists' system condition instead)
Bug Fix:
Pathfinding behavior: could stop working in Firefox/IE10 after changing layout
Bug Fix:
Image editor: arrow keys while renaming an image point would move the image point rather than the edit cursor
Bug Fix:
Possible javascript error loading a savegame with physics joints
Bug Fix:
Issues entering fullscreen from a non-fullscreen game on OS X. Should also re-center the canvas after exiting fullscreen (on all platforms).
Bug Fix:
WebSocket: did not pass along the required protocol to the actual websocket
Bug Fix:
Save/Load: the WebStorage fallback when IndexedDB was not supported did not always work. This should also fix save/loads not working on CocoonJS.
Bug Fix:
Save/Load: did not always correctly restore objects with the Persist behavior from other layouts
Bug Fix:
Replace object' did not always replace references to object expressions in expression parameters
SDK:
Fixed behavior actions with af_deprecated not being hidden

New in Construct 2 R126 (Apr 18, 2013)

New in Construct 2 R125 (Apr 10, 2013)

Add:
System trigger 'On load failed'. Useful for detecting if a save slot hasn't been saved to yet.
Add:
Z Order Bar help link now opens its new manual entry
Add:
Scirra Arcade plugin help link now opens its new manual entry
Add:
New 'Savegames' example in Start dialog
Add:
New 'Persistent layouts' example in Start dialog (shows how to use the Persist behavior)
Add:
New 'Taking screenshots' example in Start dialog
Add:
New tutorial: How to make savegames
Add:
The 'No Save' behavior's help link now points to its new manual entry
Add:
The 'Persist' behavior's help link now points to its new manual entry
Add:
New tutorial: How to make savegames
Add:
New tutorial: How to use continuous preview
Change:
Rest of manual updated to describe all r125 features
Change:
Node-webkit: no longer disables software rendering. Should help fix some severe driver issues on Mac/Linux - it should look correct, but run a lot slower, which is probably better than looking wrong and running quickly. Advise any users who complain of poor performance to update their drivers.
Change:
Updated 'Webcam' example to include a 'Download' button
Change:
When making backups of folder-based projects, Construct 2 now writes the backup to temp then copies that to the backup location, rather than backing up directly to the backup folder. This may help fix some freezes during backup (if services like Dropbox had tried to start reading the backup before C2 had finished writing it).
Change:
Keyboard: StringFromKeyCode expression used Javascript's fromCharCode() method, which proved mostly useless. Now we use our own lookup table to convert key codes to strings, which should fix basically all non-alphanumeric keys. Note this was tested on a UK keyboard, so please watch out for differences with other keyboard layouts. (Note it also may not be possible to make one conversion which works for all keyboards in the world.)
Change:
Renamed system trigger 'On loading finished' to 'On loader layout complete' to clarify it from the savegame 'On load complete' trigger
Change:
Updated and renamed AppMobi content to now refer to the Intel XDK (since Intel acquired appMobi's tools)
Bug Fix:
Cloning or copy/pasting various project elements could create things which did not work properly with save/load or the Persist behavior
Bug Fix:
User Media object: worked around a bug in Firefox's WebRTC implementation, should now work with Firefox 20+
Bug Fix:
Possible 'console is undefined' Javascript error when using continuous preview on IE
Bug Fix:
Possible blank screen if using continuous preview immediately without first previewing normally
Bug Fix:
Sprite: 'Load image from URL' did not always update all instances
Bug Fix:
Sprite: 'Start animation' in an 'On animation finished' trigger could make the object resize incorrectly

New in Construct 2 R123.2 (Mar 25, 2013)

New in Construct 2 R123 (Mar 25, 2013)

Feature:
Replace object' in event sheet (keyboard shortcut: R)
Add:
Ribbon: 'Show grid' checkbox
Add:
Audio: new Ring Modulator effect
Add:
Audio: new Distortion effect
Add:
Audio: flanger effect now takes a new 'feedback' parameter. Note this defaults to 50 whereas previously it was effectively 0; this means existing projects using flanger effects will sound different unless you change the feedback back to 0.
Add:
Windows 8 object: now triggers 'On successful purchase' or 'On failed purchase' after trying to buy the app or a product
Add:
Windows 8 object: action 'Request store listing'; condition 'On store listing received', which sets expressions 'AppFormattedPrice', 'ProductName' and 'ProductFormattedPrice'
Change:
Breaking change: 'On created' now fires just before 'On start of layout' for every object already on the layout. Previously objects placed in the layout view did not trigger 'On created', but this made it annoying to initialise objects (e.g. you'd have to pin an object both on start of layout and in 'On created'). This will probably break some projects, but it really is more convenient this way round, and hopefully all you need to do is remove the stuff you do in 'On start of layout' that is a duplicate of what happens in 'On created'.
Change:
Updated pngout to the latest version
Change:
Updated pngcrush to the latest version (1.7.52)
Change:
Updated Google Closure Compiler to the latest version
Change:
Scirra Arcade plugin: should now refresh the on-page hi-score table after a score submitted
Bug Fix:
Possible crash using Project Bar while in splitscreen view
Bug Fix:
Image editor: cropping with a selection now preserves the origin and image points relative position
Bug Fix:
Image editor: image points now remembered between frames, and is also better at remembering dialog position
Bug Fix:
Javascript error using loopindex expression after a 'wait' action
Bug Fix:
Audio: playing multiple positioned sounds on startup did not always play all of them
Bug Fix:
Layout view: dragging an unselected object snapped the drag point to the mouse (bug introduced in r122)
Bug Fix:
Picked objects were not always preserved properly after a 'wait' action
Bug Fix:
9-patch: could show seams in WebGL renderer with tiled edges (there are some known seaming situations with the canvas 2D renderer, these are still being worked on)
Bug Fix:
Windows 8 object: WindowsStoreProxy.xml now finally works for simulating app and product information in test mode (turned out to be an obscure encoding bug in Windows 8) - thanks to Henry Hoffman for the tip!
Bug Fix:
Possible infinite loop switching layout (introduced r122)
Bug Fix:
Z order bar: now refreshes object icons when their images change
Performance:
Some garbage collection optimisations to several objects
SDK:
In plugin and behavior instance constructors and onCreate, 'this.recycled' is true if the object is being re-used by the engine. If it's true, you can safely re-use member variables (e.g. setting array lengths to zero instead of assigning []) to reduce GC overhead.

New in Construct 2 R122 (Mar 14, 2013)

Feature:
Audio: effects system, including analysing audio frequency data
Add:
Two new audio examples in the Start dialog: 'Audio analyser' and 'Audio effects'
Add:
Audio: actions 'Set paused', 'Seek'
Add:
Audio: Duration, PlaybackTime and Volume expressions (to get information from currently playing sounds)
Add:
Audio: 'Set master volume' action, 'MasterVolume' expression
Add:
Audio: 'Is silent', 'Is any playing', 'Is tag playing' conditions
Change:
Exporting with PNG recompression set to 'None' now ignores any images set to PNG-8 and still exports them as PNG-32. It also skips some memory optimisation processing. Overall export times should now be semi-instant with this option, but don't use it for real production releases, since it skips a lot of very useful optimisations.
Change:
Possibly breaking change: Sin behavior now updates position just before the events run, rather than just after. This allows for objects using set position to follow without lag. However this means events can now override the position which could cause existing projects to work differently. Please watch out for anything breaking.
Change:
Possibly breaking change: Platform behavior now should follow moving platforms using the Sine behavior without any lag. However since the sequence it runs has changed, it may also cause existing projects to work differently; please watch out for anything breaking.
Change:
SCML importer: updated to support some upcoming Spriter features
Bug Fix:
Audio: no longer restarts sound effects when switching back to the tab in Chrome (sounds resume from where they left off)
Bug Fix:
Possible issue with suspending and resuming on CocoonJS
Bug Fix:
Platform: possible issue cutting jumps short when jumping up on to platforms
Bug Fix:
9-patch: javascript error when some patches had zero size
Bug Fix:
Deleting an event sheet with global variables did not always remove all references to the global variable
Bug Fix:
Browser 'Vibrate' action may not have always worked. It now definitely works on Firefox for Android and CocoonJS.
Bug Fix
Constant expressions evaluating to NaN or infinity could cause javascript errors

Add:
Touch object: expressions to get touch IDs and to get touch positions by the ID. This is often better than using the touch index since a touch ID is always the same for the lifetime of a touch, whereas the index can change. This should make it easier to implement certain multi-touch apps like dual analog controls.
Change:
WebGL renderer: layout-by-layout memory loading no longer unloads memory for objects destroyed on start of layout. This means you can place an object on a layout but destroy it immediately to indicate Construct 2 should still load its textures on startup.
Change:
appMobi directCanvas: removed our hack to support accelerometer and orientation. It caused performance problems in some games and appMobi are currently working on supporting it natively. This will temporarily break some games on directCanvas, but hopefully appMobi will be supporting it soon.
Change:
Hide address bar' is now ignored on Android, because on some devices it made the canvas display incorrectly. The option now applies exclusively to the iPhone.
Bug Fix:
Error using a constant variable in a group

XML object: did not work when in a Windows 8 app
Bug Fix:
Disabling events did not always undo properly
Bug Fix:
Comparing opacities did not always work due to a floating point rounding error

Particles: 'set rate' after creating a one-shot particles object had no effect
Bug Fix:
WebGL shaders: possible rendering glitches if all layers were transparent
Bug Fix:
Typo on start page
Bug Fix:
Platform behavior: sometimes "floated" before landing when jumping up on to a platform
Performance:
WebGL renderer: significant VRAM use reductions. This includes fixing a bug which wasted VRAM, and automatically determining if smaller texture formats can be used (such as 16-bit RGB5_A1 and RGBA4) if they can be losslessly converted. The layout-by-layout texture loading has also been optimised to reduce peak VRAM usage between layouts (avoiding momentarily having textures from both layouts loaded). This is important for mobile devices which support WebGL and have very limited memory, e.g. Firefox OS which is launching with 256MB total system memory.
Performance:
Particles: minor garbage collection optimisation which may help projects using particles extensively

Keyboard object: conditions 'On any key released', 'On key code pressed', 'On key code released', 'Key code is down'; expression 'LastKeyCode'. These use numbers for key codes which also allows for variables to be used; this should enable player-defined control setups.
Add:
Gamepad object: conditions 'On any button pressed', 'On any button released', 'Is button index down', 'On button index pressed', 'On button index released', and expression 'LastButton' to get index of last button that was pressed. This should also enable player-defined control setups.
Add:
Sprite: ImagePointCount expression
Add:
Sprite: option to disable collisions ('Collisions' property, 'Collisions enabled' condition, 'Set collisions enabled' action). Sprites with disabled collisions will not register 'On collision' events nor respond to any other kind of collision (e.g. with solid).
Add:
Windows 8 object: can now share Sprite images and data URIs. This also allows you to take screenshots and share them.
Add:
Windows 8 object: new support for 'About', 'Support' and 'Privacy' options in the Settings charm, which can be turned on and off in the object's properties. Providing these can help your app get approved in the Windows 8 Store.
Change:
BREAKING CHANGE: Collisions between objects on different layers now take in to account each layer's parallax, scale and rotation. Previously these were not taken in to account which could make objects report overlapping when they weren't actually touching on screen; now it works as expected. However, this may change when objects count as overlapping in existing projects.
Change:
When making backups Construct 2 no longer copies files or folders with the hidden attribute or with the filename beginning with a dot (e.g. .svn, .git). This should help prevent copying source control system's data in with backups making the files unnecessarily huge.
Change:
The AJAX object should now be working in appMobi directCanvas with applab 3.4.5. Note you may need to set the 'Access-Control-Allow-Origin' header on any resources you request, since a native app counts as a different domain.
Bug Fix:
Clicking 'Help on expressions' in the parameters dialog crashed in r109
Bug Fix:
Sometimes using the Touch object in a game displayed in an iframe would prevent keyboard input working
Bug Fix:
Function: in some cases the called function would still reference objects picked from the event calling the function. This was not intended; now function events start picking instances from scratch again.
Bug Fix:
Function: javascript error passing local or global variables as parameters
Bug Fix:
Local non-static variables in recursive functions did not hold unique values at each level of recursion (they acted like global variables throughout the function call). Now their values work independently in each call.
Bug Fix:
Image editor: clicking but not dragging with the line tool could cause the image to go blank

Feature
An offline manual now ships with Construct 2. By default, if you are on Windows Vista or newer, help links in Construct 2 will launch the online manual if you're connected to the internet, and the offline manual if you're not connected. You can also use a new preference setting to force Construct 2 to always launch either the online manual or offline manual.
Add
Windows 8: support for IAP (new 'Purchase product' action and 'Has product' condition). Despite the fact the code appears to be correct and does not throw any errors, I had trouble testing it successfully; please let me know how it works for you if you try it.
Add
Touch object: now can report accelerometer and orientation values on Windows 8 when the device supports it. Despite the fact the code appears to be correct and does not throw any errors, I had trouble testing it successfully; please let me know how it works for you if you try it.
Add
Balloon tips to notify you when inserting objects to hidden or locked layers
Change
Redesigned the project export process, with clearer dialogs and more help links.
Change
Awesomium: updated to RC3, with better GPU acceleration support. Awesomium games should now be faster in fullscreen, but we are still working out some issues with higher CPU usage than Chrome.
Change
Awesomium: Removed UPX compression on Awesomium DLLs, which should help prevent the long startup times some users experience.
Change
Awesomium: we have re-enabled Google's ANGLE display library, which automatically works around some graphics driver bugs. This should help fix some glitches on some systems when running Awesomium-based games.
Change
Windows 8 export: exported projects now only specify the 'Internet client' capability if your project includes the AJAX object. This is because the Windows Store requires a privacy policy if you use this capability, which can cause your submission to be rejected even if it doesn't actually access the internet. You will still need to enable the option if you use other internet accessing features like Sprite/Tiled Background's 'Load image from URL'.
Change
'Use iOS retina display' options changed to 'Never', 'iPhone only' and 'All devices'. This should allow you to use the iPhone's high-performance retina display, while avoiding using the iPad 3's very slow retina display.
Change
Replaced the stock 'Space Blaster' demo with the touch-enabled version from our recent blog post. It also runs well over Preview-on-LAN on iOS 6, so should help provide you with an example of a touchscreen game.
Change
Moved Facebook object to "Platform specific" category
Change
System: tweaks to how 'Is mobile' is detected
Change
Support for translations has been removed for the time being. The feature hasn't been finished and may not be done for a while, and in the mean time translating can cause bugs. Construct 2 now always loads the English language file and the Language tab has been removed from Preferences.
Change
A number of tools which ship with Construct 2 (such as audio encoders and PNG tools) are now also digitally signed. This should help fix issues with high security systems not being able to launch these tools.
Bug Fix
'Warp Mask' effect was broken in r105
Bug Fix
Sprite: r105 broke the use of 'set animation' in some cases. It should now be backwards compatible with how it used to work in r104 and earlier.
Bug Fix
Platform behavior: possible javascript error in IE9
Bug Fix
Platform behavior: may have had a "rough landing" when falling on a jump-thru while overlapping another jump-thru above.
Bug Fix
Platform behavior: could shift a few pixels when changing gravity direction
Bug Fix
Platform behavior: could be glitchy when on a moving platform sliding in to a solid
Bug Fix
Check failure pasting events between projects when objects were missing in the target project.

New in Construct 2 R105 (Oct 4, 2012)

Feature
Windows 8 object: support for app trial and app purchase (Is trial; Is expired trial; Is licensed; On license changed; Purchase app; TrialTimeLeft). Note the new 'Test mode' property (on by default) is used to test purchases; be sure to turn it off before publishing. An alert always appears on startup when in test mode. IAP is not yet supported, only purchasing the app itself, but is on the way.
Add
Audio object: support for the Web Audio API in Safari for iOS 6. Supports responsive polyphonic audio playback (at last). Note that Safari mutes all audio until a sound is played in a touch event, so to help work around this on iOS 6 the first played sound will be delayed until the user touches the screen. You might want to create an initial 'touch screen to continue' where you also play a sound to work around this.
Add
New 'Hide address bar' project property. Currently only works on iPhone. Note this does not work on iPad which uses a fixed address bar. Also, although the code does run on Android, I cannot get it to work: Chrome for Android uses a fixed address bar, and it simply does not seem to work for the stock browser. If anyone has working code for the stock please let me know!
Add
Shader effects can now be enabled and disabled for individual instances. Previously enabling or disabling an effect altered all instances of the same type.
Add
Construct 2 will now prompt to save changes if logging off or shutting down with an unsaved project open. In some cases, Construct 2 can now also automatically save an open project when a shutdown is forced.
Add
Facebook object: 'On ready' trigger (fires when first ready to be used, rather than having to use 'Is ready' with 'Trigger once')
Add
Drag & Drop behavior: 'Is enabled' condition
Change
A change has been made to avoid the iPhone 5 showing a web app in letterbox mode. It should now use the entire new-sized screen. Unfortunately we don't yet have an iPhone 5 so this change has not been tested - please let us know your results if you have one.
Change
PhoneGap and appMobi using phone browser are now license-only features.
Change
Breaking change: certain WebGL effects have been changed to take in to account the scale, so they look similar even at different zoom/window scale levels. However this can cause them to look different in existing projects, because they did not used to take this in to account. The following shaders have been modified: Pulse, Warp, Warp Mask, Warp ripple.
Change
'Clear background' now defaults to 'Yes' to avoid some glitchy appearances that can result with it set to 'No'.
Bug Fix
Possible problem with sprites disappearing when using an 'On created' trigger.
Bug Fix
Possible issue with screen going black when rotating through 180 degrees on Safari for iOS
Bug Fix
directCanvas: accelerometer and orientation input was supposed to be working last build, but it wasn't actually working - it should be functional now.
Bug Fix
Project bar: Crash trying to reorder layouts
Bug Fix
Pressing F4 (run project) with no projects open would crash the editor
Bug Fix
Sprite: 'set animation' in an 'on animation finished' event did not always have the intended effect

Bug Fix
Issues setting a global variable if project only contains constant global variables
Bug Fix
Audio may not have played in preview on IE9 or in preview on LAN on iOS devices

Event sheet view: some issues pasting events referencing missing local variables then undoing
SDK
Effects can now use a 'layerScale' uniform float to take in to account scaling

New in Construct 2 R104 (Sep 22, 2012)

Feature
Global and local variables have two new options: 'constant' - will not appear in 'set', 'add' or 'subtract' actions, but can be retrieved and compared (also, according to programming convention, constants are shown in uppercase); 'static' - applies to local variables only, and means the value persists and is not reset every tick. In other words, a static local variable is a global variable with a limited scope.
Add
Text object: new property to set vertical align (top, center or bottom)
Add
Gamepad object: added missing 'On button pressed' and 'On button released' triggers
Add
Touch object: new conditions 'compare orientation' and 'compare acceleration' for convenience when making motion based games, and new 'On Nth touch start', 'On Nth touch end' and 'Has Nth touch' to help with multitouch games.
Add
Audio object: the 'play' and 'play by name' actions now take a volume parameter. Setting a volume here can help avoid the sound momentarily playing at full volume until a following 'set volume' action takes effect.
Change
Breaking change: Object's 'Count' expressions are now immediately updated inside loops and subevents when new instances are spawned or created, contrary to the fact these instances do not really exist until the next top-level event. This may help fix projects broken by the last breaking change which depend on object counts in subevents, but unfortunately may again break projects which already adapted to the new behavior. Sorry - in the long run it's for the best that we make these changes.
Change
We are experimentally enabling WebGL support on mobile devices. WebGL currently only works in Firefox for Android and the Blackberry Playbook browser. However, performance can be better than canvas 2D, and it allows for effects on mobile as well.
Change
WebGL renderer: now properly handles, and recovers from, 'lost context' events. These typically happen rarely on desktops, but can happen on mobile devices if they power down while a game is showing. This should fix issues where powering up showed a game as a blank screen or reloaded the page.
Change
Touch object: now defaults 'Use mouse input' to 'Yes' when adding to a layout
Change
Touch object: deprecated 'Device orientation supported' and 'Device motion supported' conditions (they will no longer appear in the event dialog, but existing projects can keep using them). These did not actually usefully indicate whether these features were truly supported.
Change
Touch object: 'On touch start' and 'On touch end' renamed to 'On any touch start' and 'On any touch end' to clarify their purpose compared to the new 'On Nth touch start' and 'On Nth touch end' conditions
Change
Touch object: now supports accelerometer and orientation input in directCanvas
Change
Reduced the compression used on the Awesomium DLLs. This should help improve startup times for Awesomium exported apps.
Bug Fix
Possible javascript error destroying objects in behavior triggers like 'On fade ended'
Bug Fix
Possible javascript error spawning or creating objects after a 'Wait' action
Bug Fix
Triggers in subevents did not properly pick instances from conditions in parent events
Bug Fix
Sprite: 'Set scale' would undo mirroring or flipping
Bug Fix
Event sheet: crash cancelling a new comment then pressing 'down'
Bug Fix
Physics behavior: 'set velocity' could conflict with 'set position' and be overridden; should now work better
Bug Fix
Anchor behavior: should now work more reliably in crop mode and with different origin positions
Bug Fix
Platform behavior: should now be more reliable with landing on vertically moving jump-thru platforms.
Bug Fix
Possible crash dragging items between projects in the Project Bar (this is still not yet supported and will simply do nothing, but is on the todo list to add)
Bug Fix
Crash cloning an object type which had inherited behaviors from a family. This also resolves some issues copying and pasting objects between projects.
Bug Fix
Issue with Windows 8 store complaining about the UTF-8 encoding of jQuery-1.7.1.min.js. The file now includes the BOM as required.
Bug Fix
Picture editor: could not type negative numbers in to origin/image point X and Y fields.
Performance
Some minor garbage collection optimisations
SDK
To support the new lost context handling in the WebGL renderer, third party plugins that use textures need to modify their code. Please send me an email for more information on how to handle this.

New in Construct 2 R103.2 (Sep 17, 2012)

Windows 8 object: 'Set live tile text' action
Add
Gamepad object: a new Gamepad manual entry, also linked to from the object's 'Help' button
Add
User Media object: a new User Media manual entry, also linked to from the object's 'Help' button
Add
Project Bar: lots of help links added to item and folder context menus, aimed at helping beginners find information in the manual.
Add
Added some missing context menu links to the Effects dialog (family or object context menus in project/object bars)
Add
Picture editor: control+crop now crops without leaving a 1px transparent border. Note the border is recommended for most uses since it improves the quality of rotated sprites.
Change
Changed some of the closing code to try to work around further issues when closing Construct 2. It seems stable for me now, but there may be occasional crashes when closing Construct 2. This should not affect saved projects so your work is still safe even if it crashes on exit, but it may be difficult to fully fix until a reliable way to reproduce the problem can be worked out.
Change
Picture editor: 'resize canvas' now defaults to 'stretch' since it better handles the origin for new (empty) images
Bug Fix
Error exporting to Awesomium with project set to use fullscreen
Bug Fix
Separate triggers, and events in groups, are now treated as 'top level' when picking newly created objects.
Bug Fix
Drag & drop behavior accidentally blocked mouse events on Windows 8
Bug Fix
Possible crash loading files from root directories like C: \file.capx
Bug Fix
Possible Sprite object disappearing in editor if setting origin far outside image area
Bug Fix
Sprite: all instances accidentally shared the same effect parameters. Now, effect parameters can be set for individual instances.
Bug Fix
Disabling an effect in 'On create' could cause a javascript error

New in Construct 2 R102 (Sep 7, 2012)

Add
New Windows 8 plugin, to access Windows 8 app specific features like snap and sharing.
Add
New icon for instance variables to help them stand out in the event wizard
Add
Touch object, Drag & drop behavior: now supports 'MS Pointer Events', which means it now correctly detects touch input on Windows 8 touchscreen devices.
Add
Touch object: new expressions to make it easier to handle multitouch input: TouchCount, XAt, YAt, AbsoluteXAt, AbsoluteYAt (to get Nth touch positions)
Add
Touch object: new expressions to make it easier to detect swipes and the angle of motion of touches (expressions SpeedAt, AngleAt, and condition 'Compare touch speed'). Watch out since some devices seem a little erratic in reporting touch speeds, I'm not sure if this can be fixed or if the device is just not accurate enough in this case.
Add
Scirra Arcade: now supports switching in to fullscreen mode using the Browser object's 'Request fullscreen' action. This allows you to make Arcade games that can take up the entire monitor, but remember you must create a key or button the user must press since the action only works in a user-inputted event, and it is only supported in Firefox and Chrome.
Add
New system expressions CanvasToLayerX, CanvasToLayerY, LayerToCanvasX, LayerToCanvasY. Translate co-ordinates between layer and screen (canvas) co-ordinates.
Add
CocoonJS: now properly supports suspending and resuming so game pauses, stops playing audio, and stops consuming CPU when going in to the background.
Add
Browser object: 'on resized' trigger
Add
New 'Color' parameter to the Noise shader, allowing for monochrome noise
Change
Breaking change: This was actually introduced in an earlier release, but was not changelogged: the way spawned or created objects are picked in subevents has changed. Newly created instances are picked in their own event, but not picked in subsequent "sibling" subevents until the end of the next top-level event. This was done for stability reasons. Post to the forum if you need more information / workarounds.
Change
AJAX object: rewritten to not use jQuery. In theory that should mean it can now work in CocoonJS and directCanvas, but none of my tests worked with either. I'll be continuing to work on this but watch out for any changes in functionality in the mean time.
Change
Removed 'experimental' tag from the Windows 8 export option, since it now works with Windows 8 RTM and has decent platform support via the new Windows 8 object. Please note exporting to Windows 8 now requires RTM, so will no longer work on the Release Preview or earlier.
Change
Moved several platform-specific plugins to a separate 'platform specific' category.
Bug Fix
Export to Chrome Web Store: would get a blank screen if exporting a fullscreen app
Bug Fix
WebGL shader effects: the blending shaders did not always correctly take in to account the background alpha, which made them sometimes look incorrect on layers with 'Force own texture' set to 'Yes'. They should now always work correctly.
Bug Fix
mage editor: possible problems pressing both mouse buttons with the line, pencil or rectangle tools
Bug Fix
System 'Set layer effect enabled' action did not display properly in the event sheet
Bug Fix
Stacking multiple shaders involving blend shaders could display incorrectly
Bug Fix
The help link in layer properties did not work
Bug Fix
Text object: 'set text color' did not always work in the WebGL renderer
Bug Fix
Exporting to appMobi: the audio object's preload actions crashed when using directCanvas, should now work correctly
Bug Fix
The editor now ensures you cannot give effects, behaviors or instance variables in the same object the same name. Previously it was possible to cause name collisions with effects.
Bug Fix
Text: setting a webfont every tick caused a big performance drop in Firefox. It now runs fast, but still avoid setting things like this every tick if you can.

New in Construct 2 R101 (Aug 30, 2012)

Add
'Replace color' shader with tolerance setting. Allows for tinting parts of an image based on a color key.
Add
'Sharpen' shader
Add
'Emboss' shader
Add
'Pulse' shader
Add
A batch of new WebGL shader examples in the Examples folder
Add
Browser object: the 'Close' action now also closes the application in the Awesomium exporter
Change
Removed 'Experimental' tag from CocoonJS exporter, since it should be working well for most games.
Change
Origins can now be placed outside the image area. Please watch out for any bugs which only happen with origins outside the image editor - I'm not sure if there will be unexpected problems, but it was requested by a number of people.
Change
Text object: adjustments made to try and improve rendering quality in the WebGL renderer. This might also help work around driver bugs that made text look bad quality with WebGL enabled in r100.
Bug Fix
Another problem where it was possible for some images to go missing when using 'Save As'
Bug Fix
Deleted project files were not always removed when using 'Save As', making saved projects have a larger filesize than necessary
Bug Fix
Another problem with submitting Chrome Web Store apps has been fixed. The Chrome Web Store exporter is now compliant with the new tighter security requirements.
Bug Fix
Animation editor: possible crash when duplicating or deleting frames
Bug Fix
Animation editor: the frames pane no longer goes behind the image editor window when duplicating or deleting frames
Bug Fix
Awesomium: 'On mouse wheel' up and down directions were inverted
Bug Fix
Awesomium: The Browser object's 'Cancel fullscreen' action did not work
Bug Fix
Awesomium: projects where nothing was moving (e.g. a static title screen) could launch with a blank screen and not show until something changed. Now it should start up properly in this case.
Bug Fix
Awesomium: WebStorage did not save state between launches. It should now work correctly. Note the WebStorage data is saved separately for each Windows user account.
Bug Fix
Awesomium: Mouse object's 'Set cursor' should now be working. (Setting a cursor from a sprite is still not supported though)
Bug Fix
Awesomium: could not type in to Text Box objects
Bug Fix
The presence of the Browser object in a project would break appMobi directCanvas export
Bug Fix
Possible issue with fullscreen scaling options stretching badly
Bug Fix
Project bar: sound, music and file icons could display wrong after closing and reopening a project
Bug Fix
Importing GIF animations only imported one frame in r100; now should be importing all frames again.
Bug Fix
Possible crash editing properties of objects when multiple instances selected.
Bug Fix
Image editor: drawing a single pixel with the Pencil tool did not always save changes
Bug Fix
Image editor: pressing both mouse buttons at once with the erase tool could make the entire image disappear
Bug Fix
A double negative in an expression would crash the editor (e.g. --50), now reports a syntax error.
Bug Fix
Possible crash using unicode expressions and inserting an expression from the Expressions panel
Bug Fix
Objects using blending shaders would not appear correctly when on rotated layers
Bug Fix
The Water shader should no longer wrap at the edges

New in Construct 2 R100 (Aug 28, 2012)

Feature
WebGL shader effects which can be applied to objects, layers and layouts. Multiple effects can be stacked up. Families can have effects, which like instance variables and behaviors are inherited by all the objects in the family. Effects also display in the editor if WebGL is enabled in project properties, otherwise it displays as it would appear with the canvas 2D renderer. The free edition only allows two effects per project. Custom effects can be written in GLSL - see the new Effects folder in the install directory for examples.
Feature
Export Windows EXEs with Awesomium. Other platforms coming soon. Awesomium is based on a standalone version of the Chromium browser engine, allowing your HTML5 game to run similar to how it would in Chrome but as a desktop app. It also forces WebGL always on, so WebGL shader effects will always display when exported this way. There is a known performance issue which can cause the game to run slower than it does in Chrome, especially in fullscreen, and this is being investigated.
Add
Sprite, Tiled Background, Particles: the 'Effect' property has been renamed to 'Blend mode' since it is a more accurate description of what it is and helps prevent it being confused with the new effects system. It now also appears under the Effects header rather than in the object's properties. If multiple effects are used, the blend mode applies only to the last effect. There is also a new 'Effect fallback' property which appears when effects are used. This lets you specify what to do if WebGL is not supported (such as change the blend mode or destroy the object).
Add
Layers now also have a blend mode and effect fallback, like objects do. The blend mode is also used in the canvas 2D renderer, making it useful for simple layer effects where WebGL is not supported.
Add
Layer and object blend modes can now be shown in the editor
Add
System condition: 'Effects supported'. True if the shader effects are able to run (basically if WebGL is supported).
Change
Dropped 'experimental' label from AppMobi and directCanvas exporters. directCanvas should now be working for most games including tiled background and text support, except for the features listed in how to export to appMobi with directCanvas under directCanvas compatibility. Note you must have the latest version of the applab app (3.4.4+) installed for directCanvas to be working properly - be sure to check for updates on your iOS devices.
Change
Dropped 'beta' labels from Gamepad and User Media objects. These now work by default in Chrome 21+ (current stable release) without having to adjust any settings. Support should be following soon in Firefox and possibly Opera. (Not sure about Safari or IE.)
Change
Text object: no longer renders text on top of everything in the WebGL renderer, so sprites and other content can be drawn on top of text. This also means blend modes and effects can also now be applied to text objects. (The 'overlay canvas' is now also destroyed after the game starts, which should make it easier to align games when using custom CSS in a HTML page.)
Change
Behaviors dialog: now uses larger icons
Change
Platform behavior: changed moving platform detector to better handle vertically moving platforms. Please watch out in case existing projects work differently due to this change.
Change
Properties Bar: 'Add / edit' link texts swapped for 'Instance variables', 'Behaviors' and 'Effects' to make it clearer what you're clicking on
Change
Bullet behavior: the breaking change with setting angle on startup in r99 was breaking a lot of projects, making bullets fly off to the right. To improve backwards compatibility with existing projects, Bullet behavior's 'Set Angle' property is now overridden and set to 'Yes' if opening a project saved in r98 or older. If you don't want the bullet behavior to set its angle automatically, you will have to change it back to 'No' and save the project.
Change
Layout view: now uses the same sampling mode set in project properties, but you must close and reopen the project for any changes to take effect in the layout view.
Change
Export to Chrome Web Store: updated manifest to version 2. This should allow packaged apps to be submitted again.
Change
Cloning an object type now also copies instance properties (e.g. font face, size and color for text)
Bug Fix
Some crashes while exiting Construct 2 may now be fixed due to changes in C2's shutdown code.
Bug Fix
Image editor: rectangle select sometimes could not properly select the whole image
Bug Fix
Image editor: was difficult to delete collision poly points because of an issue with focus
Bug Fix
Sprite: in some cases it was possible for animation frames to be overwritten when using 'Save As'
Bug Fix
Sprite: possible crash clicking 'Edit' link to edit animations in the properties bar.
Bug Fix
Sprite: another possible problem with object picking using 'Is overlapping' in an OR block
Bug Fix
After exporting, the 'Open destination folder' option did not work for CocoonJS or the Scirra Arcade
Bug Fix
Wrap behavior: may not have worked properly if origin not in center
Bug Fix
Layout view: crash if undoing while placing a new object instance
Bug Fix
Layout view: right-click and 'Move to layer' did not always work the first time
Bug Fix
In rare cases guessing a collision poly could end up with 2 points which caused various errors. In this case the poly will be set to bounding box instead.
Bug Fix
Family behavior expressions did not always work as expected (eg. using Sprite.Physics.Density where Physics is a behavior inherited from a family and Sprite is an object in the family).
Bug Fix
Cut, copy, paste, undo & redo should now work properly when editing labels in bars (except the Properties bar which is more difficult to get working - will try to fix in next releases)
Bug Fix
Image editor: could not draw or erase the first row or column of pixels with a 1x1 brush
Bug Fix
Image editor: drawing with a smooth line could cause the first row and column of pixels in the image to become transparent
Bug Fix
Sprite: 'Load image from URL' could accidentally make the image blurry when WebGL was enabled
Bug Fix
Properties bar: pressing preview while editing a property did not save the property value before previewing
Bug Fix
Animations pane: adding an animation subfolder did not work the same as adding a top level folder
Bug Fix
Sprite's 'Spawn an object' spawning the same kind of object could crash the runtime. To work around this, in this case the spawned object is no longer picked if the same type. (Behavior is unaffected if spawning a different kind of object.)
Bug Fix
Spawning an object in an OR block with two triggers could cause a javascript error
Bug Fix
Typing the expression Mouse.-X could crash the editor. It now reports a syntax error.
Bug Fix
Using family behaviors it was possible to end up with two behaviors with the same name in an object, which caused problems. The editor now prevents you from adding objects to families when this would happen.
Bug Fix
The layout's snap settings in the ribbon should now properly update when switching layouts.
Bug Fix
Project Bar: could keep scrolling after dragging an item.
Bug Fix
Passing numbers to system expressions where strings are expected (e.g. tokenat()) should no longer cause javascript errors
Bug Fix
Global objects in a family sometimes would not be able to be destroyed
Performance
Particles object: optimised to render more efficiently in the WebGL renderer. (Canvas 2D renderer performance is unaffected.) Can now be up to twice as fast, although usually the benefits will be smaller. Please watch out for any visual differences though.
SDK
The 'Effect' property of all official plugins has been replaced by the new built-in 'Blend mode' property. Any third party plugins using a similar 'Effect' property should remove it and any code that changes the composite mode/blend mode in the runtime, since this is now done automatically. C2 will automatically convert the 'Effect' property from old projects to the new build in one. Post in the Javascript SDK forum for more information.

Add
Image editor: new brush drawing tool
Add
Image editor: new erasor tool (works the same as brush with transparent selected)
Add
Image editor: new line drawing tool
Add
Image editor: 'Tolerance' option for the flood fill tool
Add
Image editor: fields to type in the co-ordinates for both image points and collision poly points
Add
Image editor: new color picker tool (note: a shortcut for this is just to hold control and click a color with another tool)
Add
Families now have an overlay placed over their icon to help identify them as families
Add
Added a link to our YouTube channel to the start page
Add
Links to the Scirra Store in the editor
Change
The 'Preview mode' project property has finally been removed, along with the 'File' preview mode. All projects will now always use HTTP preview mode. This has been done because 'File' mode was almost completely useless - due to browser security limitations in 'File' mode, even the most trivial games would not work.
Change
Breaking change: the Bullet behavior no longer sets its angle of motion to the object angle on the first tick, if 'Set Angle' is 'No'. (If 'Set Angle' is 'Yes', this still happens.) Workaround if your game changes: add 'set angle of motion' actions, or change 'Set Angle' to 'Yes'.
Change
Image editor: new origin and imagepoint icons
Change
Export to CocoonJS: now exports a zip of all files, saving you having to manually zip them yourself
Change
The Text and Tiled Background objects have been enabled for directCanvas. They may not work in app-lab's 'test anywhere'/'test over wifi' until appMobi update it with support, but should work on iOS when building an app. A number of directCanvas bugs have also been fixed by appMobi (similarly also won't be in applab until next update).
Change
The preview server may have been responsible for hanging or crashing when exiting Construct 2. Changes have been made to the shutdown process to make it more reliable, and this should fix some issues with closing Construct 2.
Change
Start page: simpler wording used for many of the links
Change
CocoonJS & directCanvas: the presence of the AJAX and Facebook plugins should no longer break the whole game. For now these plugins are disabled on these platforms until workarounds can be implemented.
Change
CocoonJS & directCanvas: the letterbox fullscreen modes have been disabled on these platforms because they are not supported - it will fall back to the ordinary Scale mode instead, until support can be implemented.
Change
CocoonJS: will log to the debug console whenever unsupported features are used. This includes using Text Box or Button controls, trying to set web fonts, using WebStorage session storage, and requesting or exiting fullscreen. Hopefully this will make it easier to find which parts of your project are not supported. (Enable debug mode and press the FPS counter to open the debug console.)
Change
Improved error message if you have duplicate plugin or behavior IDs
Bug Fix
Could not type in to the properties bar while image editor was open (made it impossible to change animation speed)
Bug Fix
Exporting to directCanvas was broken in r98
Bug Fix
Physics: the 'Apply torque to position' action broke when minifying the project on export
Bug Fix
Physics: some very large objects with detailed collision polygons may not have collided properly
Bug Fix
Image points dialog: could not type 'I' in to name of image point in r98
Bug Fix
Firefox and Chrome should no longer prompt mysterious "Script error" alerts when previewing.
Bug Fix
Facebook plugin: could cause a javascript error if request for hi-scores failed (e.g. because not logged in)
Bug Fix
Sprite: fixed another possible error in 'Is overlapping' in OR blocks
Bug Fix
Duplicating a layout no longer duplicates the invisible instances of Array, Dictionary etc.

New in Construct 2 R98 (Jul 7, 2012)

Feature
Experimental CocoonJS Ads plugin. Display banner ads or fullscreen ads during the game to help earn some money from your game.
Add
Image editor: new rectangle select tool - helps with simple cropping and adjustments
Add
Image editor: clipboard support - cut and paste images in to and out of other programs.
Add
AppMobi object: action to hide device status bar (for true fullscreen)
Add
Text object: new 'line height' property. Adjust the spacing between lines for your text objects.
Add
Image editor: collision poly points can now be nudged with arrow keys (like image points can)
Add
Image editor: shortcut key 'I' to add new image point when image points tool selected
Add
Image editor: options to apply origin, image points and collision poly to all animations in the object
Add
Button: 'Auto font size' property, same as Text Box's. Also changed both to default 'Auto font size' to 'Yes' instead of 'No'.
Add
Image editor: now warns with a balloon tip when using a tiled image which isn't power-of-two size (e.g. 32x32, 64x64, 128x128...) Usually power-of-two sizes can be drawn seamlessly even when using opacity, zoom, rotation and floating point positioning. On the other hand non-power-of-two sizes can appear with seams, or in the WebGL renderer they can appear blurry. (This only helps Tiled Background objects - when using Sprites, the size of the image does not matter.)
Add
Event sheet: 'Enter' key can now edit selected event variables
Change
New image editor tool icons
Change
Using Safari for Windows without Quicktime installed used to crash on an 'Audio is undefined' javascript error. Now instead the following message will appear, and the game will continue to run without audio: "It looks like you're using Safari for Windows without Quicktime. Audio cannot be played until Quicktime is installed."
Change
The image editor warning for large images has been increased from 1024 to 2048, since even all major mobile devices can handle 2048x2048 sized textures. However larger than that is definitely not supported by all devices, so you should certainly heed this warning if you see it.
Change
In some cases, in an OR block there would technically be no instances picked, so object expressions would return 0. This seemed to have some unexpected side-effects though, and prevent some events which look like they should work from working. So now in OR blocks if no instances are picked but instances exist, an arbitrary (first) instance is used to get the expression from.
Change
Image editor: shortcut to pick a color changed from shift+click to control+click
Change
Overlay canvas (for WebGL text rendering) is positioned with different code now, which should make it work better with some kinds of CSS if modifying the exported page.
Change
Facebook plugin: Facebook have started issuing user IDs as 15-digit numbers (in the trillions, up from a previous 9-digit number). This caused problems for the UserID expression which returned an int and ended up truncating the number. The UserID expression now returns a float, which can just about fit the number within its integer precision range.
Bug Fix
Adding a non-layout instance (e.g. Array, Dictionary) when an event sheet tab is open now correctly inserts an invisible instance rather than making a useless object with no properties.
Bug Fix
Image editor: possible check failures trying to draw outside image area
Bug Fix
Image editor: cropping an entire animation could occasionally make objects "wobble" by a pixel throughout the animation. This should no longer occur and it should stay smooth.
Bug Fix
Construct 2 should no longer lock image files after importing them or using them in the editor. (Previously importing an external image file could make the external file uneditable until you closed Construct 2 or at least the image editor.)
Bug Fix
Possible javascript error minifying projects using the Physics behavior
Bug Fix
Possible javascript error in Sprite's 'Load image from URL' action.
Bug Fix
Image editor: 'Duplicate animation' may not have worked correctly in some cases.
Bug Fix
Shortcut to add a comment (Q) now works when event variable or another comment is selected
Bug Fix
Form controls (Text box, Button) no longer jitter when using a fullscreen mode
Bug Fix
Sprite: 'Is overlapping' conditions did not always work properly in an OR block
Bug Fix
Import Audio dialog: would sometimes incorrectly rename .m4a or .ogg files with the same name if imported separately rather than all at once.

New in Construct 2 R97 (Jun 30, 2012)

Feature
Image editor tools: pencil, fill and rectangle (more coming soon). New color picker dialog with support for primary and secondary colors, alpha channels, RGB/HSL, and drawing with transparent to erase. Full undo support (including for options like Mirror and Rotate which weren't undoable before), although closing the image editor removes all drawing undo points and replaces them with a single 'edit image' undo point. (The tool icons are also temporary and will be replaced soon!)
Add
Image editor: status bar, with information like zoom level, mouse position, image size, image format and the point positions for collision polygons and origin/image points.
Add
Image editor: now allows multiple selection of collision poly points (hold control or shift while selecting), a new 'Select all' option, and dragging multiple points at once.
Add
Text box: new 'Auto font size' property, which defaults to 'Off'. This stops Construct 2 overriding the font-size property according to the layer scale, so you can properly set your own font size.
Change
Invisible object types (Array, Dictionary, XML etc.) previously only were available on the layout they were inserted to. Now they default with their 'Global' property set to 'Yes', which makes them available on any layout. In addition to that, if the layout they are inserted to is deleted, Construct 2 now moves their invisible instances to the first layout. This prevents you from getting useless objects with no instances after deleting the layout the object was added to. Hopefully this will prevent future confusion with these objects.
Change
Lots of users still did not check for browser errors and this could cause difficulties in bug reports. In order to make this easier, whenever there's a javascript error, it is reported by a message box without you having to open the browser console. This makes it impossible to miss javascript errors, and hopefully should make diagnosing problems easier. (This is only done in preview - errors in exported projects are still reported quietly in the console.)
Change
The way changing layout is handled is now done slightly differently: it still takes a tick to change the layout if going to a new layout, but if two 'go to layout' or 'restart layout' actions were issued in the same tick, it used to go to the second layout (because the second action would override the first). Now instead it goes to the first one (because the second action in the same tick does not override it).
Change
AJAX object: now automatically converts Windows-style line breaks (\r\n) to Linux style (\n). This shouldn't break anything, unless you somehow depended on the Windows format.
Change
Breaking change: Layer zoom rates no longer affect the scaling caused by a fullscreen mode. This means if you used a HUD on a layer with the zoom rate set to 0 and letterbox scale mode set, the HUD will now scale, whereas previously it would have remained 1:1. This may break some existing projects which relied on the old behavior, but the new behavior is probably more useful.
Bug Fix
Event includes did not work (sorry - caused by overzealous refactoring for the performance improvement last build)
Bug Fix
The 'Set height' action caused a javascript error (more overzealous refactoring)
Bug Fix
Exported projects did not work if not minified.
Bug Fix
Layout view: Ctrl+E shortcut (go to event sheet) would crash if the layout had no associated event sheet
Bug Fix
Renaming project files could break the project
Bug Fix
Image editor: 'sticky buttons' problem should no longer happen when switching tool
Bug Fix
Custom movement: 'Reverse' action could cause check failures in beta releases
Bug Fix
Layout view: correct mouse cursor used when resizing rotated objects
Bug Fix
Sin behavior: now takes in to account sprite changing to different sized frames

New in Construct 2 R96 (Jun 26, 2012)

Add
Can now import scenes, layers and actors from GameSalad projects (.gameproj and .gsproj, from the Mac and Windows creators respectively). For more information see the tutorial Importing GameSalad scenes and actors.
Add
AJAX: long overdue support for POST requests with data
Add
System expressions URLEncode and URLDecode (useful for AJAX requests)
Add
Mouse: new action 'Set cursor from sprite'. Set a custom cursor image from a Sprite object. Only works in Firefox and Chrome, may not work on other OSs either (e.g. Mac). Also has some limits on image size or it won't work. Prefer this instead of positioning a sprite at Mouse.X and Mouse.Y, because there is much less lag on the mouse movements this way.
Add
System action: 'Set canvas size'. Only really useful for non-fullscreen games since the runtime effectively does 'Set canvas size' each time the window is resized for fullscreen games.
Add
Keyboard shortcuts for 'up a folder' in the event wizard: 'U' or 'Page up'
Add
Physics: added condition 'Is sleeping'
Change
Breaking change: the Platform behavior has always only worked to the nearest pixel, but now handles the way it rounds its movement differently. This fixes some issues on slopes where the player would not accelerate properly or move at different speeds in certain directions. However, it may alter the pixel-perfectness of the movement. Let me know if you notice any important differences in platform movements.
Change
Dictionary: help link now opens its manual entry
Bug Fix
Removing objects from families could cause the project to become unopenable
Bug Fix
Sprites with 1x1 images did not export correctly with the new spritesheeting feature
Bug Fix
File sizes were not always correctly identified on export. The loading progress bar should now be more accurate.
Bug Fix
AJAX object broke games on iOS and CocoonJS because of a missing feature in their javascript engines. It's now worked around.
Bug Fix
Better support for object with negative sizes (via properties bar and 'set size' action)
Bug Fix
When previewing, in rare cases it was possible for the browser to fail to display the game, and you had to press refresh to make it work. A change has been made to try to prevent this from happening.
Bug Fix
XML plugin: the NodeCount expression was incorrectly marked as returning a string, now returns a number
Performance
The runtime has been refactored to compress better under Closure Compiler (the 'minify' option on export). An empty project's javascript minified and zipped now has an overhead of just 19kb. Also, the javascript code for actions, conditions and expressions not actually used in the project are now removed by Closure Compiler when exporting. This helps reduce the download size and improve startup time on mobile (since there is less javascript to parse).

New in Construct 2 R95 (Jun 15, 2012)

New in Construct 2 R94 (Jun 13, 2012)

New in Construct 2 R93 (Jun 7, 2012)

Feature:
Loader layouts: can now set the first layout to be a 'Loader layout'. This means when the project is loading it will load that layout first and display it as soon as possible. While the rest of the project is loading you can use the 'loadingprogress' system expression to make your own customised loading screens. Use as little artwork as possible on the loader layout to ensure it loads quickly itself.
Add:
'Loader style' project property. Choose the default loader style: progress bar & logo (the default), progress bar only, percentage text (just some text reading e.g. "50%"), or nothing (not recommended since more loading feedback is better). Note this is still shown when loading the loader layout if it is taking a while to load (it goes: default loader -> loader layout -> game), so choosing an alternative like 'percentage text' might be wise even if you use a loader layout.
Add:
Sprite, Tiled Background: 'Load image from URL' action (also triggers 'On image URL loaded' when complete). Note as per AJAX requests if a URL on a different domain is used, that server must have Cross-Origin Resource Sharing (CORS) set up to allow the request, otherwise it won't work. (Note: you can achieve limited per-layout image loading by importing images as project files and using these actions to load them at runtime.) Note CORS needs IE10+, Opera 12+ (although you can still load same-domain images on IE9 and Opera 11); supported everywhere else.
Add:
AJAX: support for progress events ('On progress' trigger, 'Progress' expression). Allows for making progress bars for long-running AJAX requests. Especially useful if AJAX requesting a large project file. Needs IE10+, Opera 12+, Android 3+; supported everywhere else.
Add:
Installer: checkbox on finish page to check for a graphics driver update to try and pre-emptively solve driver problems
Add:
Installer; checkboxes on finish page to get Google Chrome or Mozilla Firefox, since we recommend using one of these browsers with Construct 2.
Bug Fix:
Touch input was misaligned in iOS retina mode
Bug Fix:
Construct 2 can now save projects to network paths (provided it has write access)
Bug Fix:
Duplicating layouts did not number them consecutively
Bug Fix:
Sprite: 'Is overlapping' conditions did not always check all combinations of pairs of instances.
Bug Fix:
Text: sometimes showed large numbers inaccurately
Bug Fix:
Could name an object with unprintable characters which caused problems

New in Construct 2 R92 Beta (May 29, 2012)

Feature: Project Bar: new 'Files' folder. Allows for importing any files to the project. Useful to store any data files (e.g. .xml, .json, .txt...) or any other purpose where external files are useful, e.g. embedding video files, binaries, documents, etc.
Feature: Spritesheeting in to 512x512 tiles on export. Helps reduce download size, especially with 256-color/PNG-8 images. Each tile only contains one Sprite's animations (different objects will not be mixed on one tile). Breaking change: this may break third party plugins that alter Sprite's images. Any affected developers please post to the SDK forum and I'll help you make the necessary changes.
Add: AJAX: 'Request project file'. Allows loading of project files through AJAX. Useful to then load the result in to the Array, Dictionary or XML plugins, which could be handy for making level editors and such.
Add: Support for iOS Retina displays. Allows for hi-res artwork and crisper text on hi-res devices like the iPhone 4S and iPad 3. Can be disabled in project properties ("Use iOS retina display") if you prefer to leave it low-res and upscale, which is lower quality but can improve performance. Enabled by default.
Add: At long last, browsers are beginning to add support for point sampling in canvas 2D. This means in future it should no longer be necessary to use WebGL just to get point sampling for retro games. Browser support is in Chrome 21+, not sure about other browsers yet, but it's at least 3 months until support reaches stable browser releases.
Add: System expression 'CPUUtilisation'. Percentage of the last second spent in the application logic. Note this is an approximation only, except for browsers with support for high-resolution timers (Firefox 15+, Chrome 21+). The rest of the time will be either idling or waiting for the GPU to finish rendering - you can't tell.
Add: System expressions ViewportLeft, ViewportTop, ViewportRight, ViewportBottom. Get the viewport position for a particular layer.
Add: Support for high-resolution timers in Chrome 21+. (Was already supported in Firefox 15+)
Add: Project bar: 'family behaviors' added to right-click menu for families
Change: Dictionary: removed unused property accidentally left in
Change: Estimated project size now takes in to account the image format set in the image editor, but only very crudely: PNG-8 is assumed to be half the size and JPEG assumed to be a quarter the size. Remember the only real way to tell is to export your project.
Bug Fix: Crash adding an object type to a family with family behaviors
Bug Fix: The new letterbox fullscreen options in r91 were accidentally left out of the 32-bit version of Construct 2
Bug Fix: Some broken-when-minifying bugs should now be fixed
Bug Fix: Possible crash in the Physics behavior
Bug Fix: XML: can now return text longer than 4096 characters on Firefox
Bug Fix: WebKit based browsers (Chrome, Safari): fix for some browser bugs - Chrome sometimes made pixelly games look blurry, and Safari sometimes went blank when changing orientation. A hack as been added to work around this.
Performance: Performance improvement for some mobile browsers after exporting. It may be worth re-testing your games on mobile if you have already since the framerate may now be measurably higher in places, depending on the system. Note the optimisation is only applied on export - if you use Preview-on-LAN feature it won't be any faster.
SDK: The preview server now serves up files from the new project 'Files' folder. This could be useful for third party plugins that need to use other files. However, only a fixed list of MIME types are supported; if you need the preview server to support a new MIME type, let me know and I can add it.
SDK: New project file parameter type (AddFileParam). Dropdown list to select a file from the project's 'Files' folder. Returns a string of the filename, which is exported to the same folder as index.html (so can be used as a relative URL). Used by AJAX.

New in Construct 2 R91 Beta (May 19, 2012)

Feature: Family behaviors. As with family instance variables, these are behaviors you can add to the family itself, then all objects in the family inherit that behavior.
Feature: New fullscreen modes: "Letterbox scale" and "Letterbox integer scale". Letterbox scale is like scale but preserves the aspect ratio and shows black bars at the edges if necessary. Letterbox integer scale is like the former but the scale will only be an integer, e.g. 2x, 3x, 4x... This is intended to make it easy for retro-style games to upscale evenly. Both options should also make it easier to design games for a specific aspect ratio. Also supported by the Browser object's 'request fullscreen' action, so in-page games can for example switch in to fullscreen integer scale letterbox mode. It is difficult to test this since there are so many combinations of browser and export option, so watch out for issues.
Feature: New official 'Dictionary' plugin. Store values under keys, e.g. set "key" to "value". (Basically Hashtable from Classic, but renamed.) Also has JSON support like Array.
Add: System expression 'zeropad' (based on Classic's) - pad number with zeroes and return as string, e.g. zeropad(45, 5) returns "00045"
Add: appMobi object: help link now opens its new manual entry
Add: WebStorage: new 'On Quota Exceeded' trigger. Fired when exceeded the browser's limitations on how much data can be stored in Web Storage (often around 5mb).
Add: Facebook object: 'HiscoreUserID' expression, to get the user ID (rather than the name) of the user who got the hi-score.
Add:Fade behavior: 'active at start' property, and 'start fade' action. Allows starting the fade whenever you want rather than immediately.
Change:Export to appMobi: help link now opens the new tutorial
Change:Destroyed instances are now fully removed between top-level events (like Construct Classic). This means 'for each' loops and the object counts are updated for destroyed instances after the top-level event or group finishes.
Bug Fix:Breaking change: the parallax origin for parallax layers would change if the window size changed. This could cause parallax to become misaligned when using a fullscreen mode. On the other hand the change could cause existing projects that were working to become misaligned. I think it is much more logical for it to work the new way, so hopefully everyone can work with the new way.
Bug Fix:Ampersands (&) would not appear in parameter descriptions
Bug Fix:CocoonJS: sometimes audio in the 'music' folder did not play
Bug Fix: 'Is on screen' was always false for the first tick of a layout, even if the objects were initially on screen.
Bug Fix: OR blocks did not always work correctly as a sub-event to a 'for each' loop.
Bug Fix: 'Else' following an event with subevents did not always work correctly.
Bug Fix: PhoneGap Build: workaround for crash on Android with the PhoneGap 1.7 update. To solve the issue all apps now require the "access network state" permission, since this appears to be a new requirement for PhoneGap itself to work.
SDK: Plugins and behaviors can now specify multiple dependency files by semicolon separating them, e.g. "dependency": "file1.js;file2.js;file3.js"
