After almost two years in development and a few months of Beta, Phaser 3 is finally available.   Phaser is an open source HTML5 game framework with a massive communityPhaser3 behind it.   We did a full Phaser with TypeScript tutorial series using the previous version of the framework, and I have long been a huge fan.  The 3.0 release has had a long and painful gestation period that you can read about in detail here.  This new release is built around a new more modular design, has an all new renderer, state manager and more.  It is an early release though and documentation and tutorials are nowhere near the 2.x levels.  For the record, the Phaser 2.x branch is continuing development as Phaser Community Edition.


Details of the announcement from the Github page:

After 1.5 years in the making, tens of thousands of lines of code, hundreds of examples and countless hours of relentless work: Phaser 3 is finally out. It has been a real labor of love and then some!

Please understand this is a bleeding-edge and brand new release. There are features we've had to leave out, areas of the documentation that need completing and so many cool new things we wanted to add. But we had to draw a line in the sand somewhere and 3.0.0 represents that.

For us this is just the start of a new chapter in Phaser's life. We will be jumping on bug reports as quickly as we can and releasing new versions rapidly. We've structured v3 in such a way that we can push out point releases as fast as needed.

We publish our Developer Logs in the weekly Phaser World newsletter. Subscribe to stay in touch and get all the latest news from us and the wider Phaser community.

You can also follow Phaser on Twitter and chat with fellow Phaser devs in our Slack and Discord channels.

Phaser 3 wouldn't have been possible without the fantastic support of the community and Patreon. Thank you to everyone who supports our work, who shares our belief in the future of HTML5 gaming, and Phaser's role in that.

Happy coding everyone!

Cheers,

Rich - @photonstorm


I have downloaded the new release and am playing around with it as I write this, so stay tuned for more.

As Phaser moves closer and closer to their final release, Phaser 2.4.9 RC4 was just released.  For a release candidate, this one has several features.  Here is the change log for this release:

* Phaser.Line.intersectsRectangle checks for intersection between a Line and a Rectangle, or any Rectangle-like object such as a Sprite or Body.
* Group.getClosestTo will return the child closest to the given point (thanks @Nuuf #2504)
* Group.getFurthestFrom will return the child farthest away from the given point (thanks @Nuuf #2504)
* Animation.reverse will reverse the currently playing animation direction (thanks @gotenxds #2505)
* Animation.reverseOnce will reverse the animation direction for the current, or next animation only (thanks @gotenxds #2505)
* The way the display list updates and Camera movements are handled has been completely revamped, which should result is significantly smoother motion when the Camera is following tweened or physics controlled sprites. The `Stage.postUpdate` function is now vastly reduced in complexity. It takes control over updating the display list (calling `updateTransform` on itself), rather than letting the Canvas or WebGL renderers do this. Because of this change, the `Camera.updateTarget` function uses the Sprites `worldPosition` property instead, which is now frame accurate (thanks @whig @Upperfoot @Whoisnt @hexus #2482)
* Game Objects including Sprite, Image, Particle, TilemapLayer, Text, BitmapText and TileSprite have a new property called `data`. This is an empty Object that Phaser will never touch internally, but your own code, or Phaser Plugins, can store Game Object specific data within it. This allows you to associate data with a Game Object without having to pollute or change its class shape.
* TilemapLayers will now collide properly when they have a position that isn't set to 0x0. For example if you're stitching together several maps, one after the other, and manually adjust their `scrollX/Y` properties (thanks @Upperfoot #2522)
* There are a bunch of new Phaser consts available to help with setting the angle of a Game Object. They are `Phaser.ANGLE_UP`, `ANGLE_DOWN`, `ANGLE_LEFT`, `ANGLE_RIGHT`, `ANGLE_NORTH_EAST`, `ANGLE_NORTH_WEST`, `ANGLE_SOUTH_EAST` and `ANGLE_SOUTH_WEST`.
* Math.between will return a value between the given `min` and `max` values.
* InputHandler.dragDistanceThreshold gives you more fine control over when a Sprite Drag event will start. It allows you to specify a distance, in pixels, that the pointer must have moved before the drag will begin.
* InputHandler.dragTimeThreshold gives you more fine control over when a Sprite Drag event will start. It allows you to specify a time, in ms that the pointer must have been held down for, before the drag will begin.
* InputHandler.downPoint is a new Point object that contains the coordinates of the Pointer when it was first pressed down on the Sprite.
* There are two new Phaser consts available, for help with orientation of games or Game Objects. They are `Phaser.HORIZONTAL`, `Phaser.VERTICAL`, `Phaser.LANDSCAPE` and `Phaser.PORTRAIT`.
* InputHandler.dragStopBlocksInputUp is a boolean that allows you to control what happens with the input events. If `false` (the default) then both the `onInputUp` and `onDragStop` events will get dispatched when a Sprite stops being dragged. If `true` then only the `onDragStop` event is dispatched, and the `onInputUp` is skipped.
* Group.inputEnableChildren is a new property. If set to `true` will automatically call `inputEnabled = true` on any children _added_ to, or _created_ by, the Group.
* PIXI.DisplayObjectContainer.ignoreChildInput is a new property. If `true` then the children will _not_ be considered as valid for Input events. Because this has been applied to `DisplayObjectContainer` it means it's available in Group, Sprite and any other display level object. Using this boolean you can disable input events for all children in an entire Group, without having to iterate anything or deep-set flags.
* InputHandler._pointerOverHandler and _pointerOutHandler have new arguments `silent` - if `true` then they will not dispatch any Signals from the parent Sprite.
* Pointer.interactiveCandidates is a new Array that is erased and re-populated every time this Pointer is updated. It contains references to all of the Game Objects that were considered as being valid for processing by this Pointer, during the most recent update. To be valid they must have suitable a `priorityID`, be Input enabled, be visible and actually have the Pointer over them. You can check the contents of this array in events such as `onInputDown`, but beware: it is reset every update.
* Pointer.swapTarget allows you to change the `Pointer.targetObject` object to be the one provided. This allows you to have fine-grained control over which object the Pointer is targeting.
* Input.setInteractiveCandidateHandler allows you to add a callback that is fired every time `Pointer.processInteractiveObjects` is called. The purpose of `processInteractiveObjects` is to work out which Game Object the Pointer is going to interact with. It works by polling all of the valid game objects, and then slowly discounting those that don't meet the criteria (i.e. they aren't under the Pointer, are disabled, invisible, etc). Eventually a short-list of 'candidates' is created. These are all of the Game Objects which are valid for input and overlap with the Pointer. If you need fine-grained control over which of the items is selected then you can use this callback to do so. The callback will be sent 3 parameters: 1) A reference to the Phaser.Pointer object that is processing the Items. 2) An array containing all potential interactive candidates. This is an array of `InputHandler` objects, not Sprites. 3) The current 'favorite' candidate, based on its priorityID and position in the display list. Your callback MUST return one of the candidates sent to it.
* Group.onChildInputDown is a new Signal that you can listen to. It will be dispatched whenever any immediate child of the Group emits an `onInputDown` signal itself. This allows you to listen for a Signal from the Group, rather than every Sprite within it.
* Group.onChildInputUp is a new Signal that you can listen to. It will be dispatched whenever any immediate child of the Group emits an `onInputUp` signal itself. This allows you to listen for a Signal from the Group, rather than every Sprite within it.
* Group.onChildInputOver is a new Signal that you can listen to. It will be dispatched whenever any immediate child of the Group emits an `onInputOver` signal itself. This allows you to listen for a Signal from the Group, rather than every Sprite within it.
* Group.onChildInputOut is a new Signal that you can listen to. It will be dispatched whenever any immediate child of the Group emits an `onInputOut` signal itself. This allows you to listen for a Signal from the Group, rather than every Sprite within it.
* Phaser.Weapon is a brand new plugin that provides the ability to easily create a bullet pool and manager. Weapons fire Phaser.Bullet objects, which are essentially Sprites with a few extra properties. The Bullets are enabled for Arcade Physics. They do not currently work with P2 Physics. The Bullets are created inside of `Weapon.bullets`, which is a Phaser.Group instance. Anything you can usually do with a Group, such as move it around the display list, iterate it, etc can be done to the bullets Group too. Bullets can have textures and even animations. You can control the speed at which they are fired, the firing rate, the firing angle, and even set things like gravity for them. Please see the Documentation for more details, or view the [Weapon examples](https://github.com/photonstorm/phaser-examples/tree/master/examples/weapon) in the Examples repo.

### Updates

* TypeScript definitions fixes and updates (thanks @wingyplus @monagames @marineorganism @obamor @BaroqueEngine)
* Docs typo fixes (thanks @seanirby @johnrees)
* The TypeScript defs ambient declaration has been updated to make it compatible with the SystemJS loader (thanks @monagames)
* You can no longer intersect check a Body against itself (thanks @VitaZheltyakov #2514)
* The mobile template has been updated (thanks @cryptographer #2518)
* Video.onComplete wouldn't fire on iOS if the user hit the 'Done' button before the video had finished playing. It now uses the `webkitendfullscreen` event to detect this, and dispatches the `onComplete` signal should that event fire (thanks @kelu-smiley #2498)
* Sound.addMarker now has a default value for the `duration` argument (1 second) to avoid the DOM Exception 11 error if you accidentally miss it out (thanks @mari8i #2508)
* Removed the `Stage.updateTransform` calls from the main game loop, because it happens automatically as part of `Game.updateLogic` anyway, so was duplicating the workload for no reason.
* TilemapLayer.postUpdate could potentially be called several times per frame (depending on device frame rate), which would cause multiple texture redraws, even though only the last texture is used during rendering. This has now been modified so that the local TilemapLayer canvas is only re-rendered once per frame, during the rendering phase, and not during the logic update phase.
* Group.preUpdate now iterate through the display list forwards, instead of in reverse, to match it with how `Stage.preUpdate` works.
* Stage.postUpdate is now a lot smaller, with no conditional branching if there is a Camera Target or not.
* Within RequestAnimationFrame both `updateRAF` and `updateSetTimeout` now only call `game.update` if `isRunning` is true. This should avoid asynchronous Game destroy errors under environments like Angular (thanks @flogvit #2521)
* Group.removeAll has a new argument `destroyTexture` which allows you to optionally destroy the BaseTexture of each child, as it is removed from the Group (thanks @stoneman1 #2487)
* PluginManager.remove has a new argument `destroy` (defaults to `true`) which will let you optionally called the `destroy` method of the Plugin being removed.
* Cache.getJSON used to incorrectly bring back a deep-copy of the Phaser.Utils object, instead of just a clone of the JSON object requested (thanks @drhayes #2524 #2526)
* The `DisplayObject.renderOrderID` used to run in reverse. I.e. in a display list with 10 sprites on it, the first sprite (at the bottom of the list, rendering behind all the others) would have a `renderOrderID` of 9, where-as the top-most sprite, rendering above all others, would have a `renderOrderID` of 0. While this didn't cause any side-effects internally, it's arguably illogical. So the process has been reversed, and `renderOrderID`s are now accumulative, starting at zero each frame, and increasing as it iterates down the display list. So the higher the ID, the more "on-top" of the output the object is.
* `InputHandler.validForInput` and `Pointer.processInteractiveObjects` have been updated to reflect the new `renderOrderID` sequence (see above).
* Group.add has a new optional argument `index` which controls the index within the group to insert the child to. Where 0 is the bottom of the Group.
* Group.addAt has been refactored to be a simple call to `Group.add`, removing lots of duplicate code in the process.
* Group.create has a new optional argument `index` which controls the index within the group to insert the child to. Where 0 is the bottom of the Group. It also now makes proper use of `Group.add`, cutting down on more duplicate code.
* Group.createMultiple now returns an Array containing references to all of the children that the method created.

### Bug Fixes

* Arcade Physics Body incorrectly positioned if the Sprite had a negative scale (see http://www.html5gamedevs.com/topic/22695-247-248-body-anchoring-any-migration-tips/) (thanks @SBCGames @icameron @Nuuf @EvolViper #2488 #2490)
* InputHandler.checkPointerDown had an incorrect single pipe character |, instead of an OR check ||, and an `isDown` check, causing Button Over events to fail (thanks @pengchuan #2486)
* BitmapText objects with lines greater than `maxWidth` now handle alignment values correctly, causing them to properly center align (thanks @kevinleedrum  #2499 @crippledcactus #2496)
* Text has a new private method `measureLine` which is used to calculate the final Text line length, after factoring in color stops and other style changes. This should prevent characters from becoming truncated (thanks @TadejZupancic #2519 #2512)
* Sometimes the browser would cause a race condition where any connected Game Pads were being detected before the callback had a chance to be established. Also sometimes the rawPad references would become stale, and are now checked constantly (thanks @cwleonard #2471)
* Sound.isPlaying was set to false when doing an audio loop, but never set back to true if it's a sound not using a marker (thanks @TheJasonReynolds #2529)
* Phaser.Rectangle.aabb would fail if the Rectangles used negative offsets. It now calculates the bounds accurately (thanks @fillmoreb #2545)

GameDev News

22. April 2016

 

Phaser, the popular HTML5 based 2D game engine, just released version 2.4.7.  This may sound extremely familiar and that’s because I just recently announced the 2.7 RC release.  Generally there is a fair bit of a time between a release candidate and a final release so I figured I would mention the release candidate.  Oops.  Guess not in this case. 

 

Anyways, Phaser 2.4.7 is one of the final releases of the Phaser 2.x series, when it will be replaced with Lazer (Phaser 3.x).  The final release for Phaser 2.x is scheduled to be 2.5, after which no new features will be added and it will be maintenance only.  For being so far along in the frameworks lifecycle, it’s actually rather shocking how large this release is:

New Features
  • Added P2.Body.thrustLeft which will move the Body to the left by the speed given (thanks James Pryor)
  • Added P2.Body.thrustRight which will move the Body to the right by the speed given (thanks James Pryor)
  • Polygon now takes an array of arrays as a new type when constructing it: [[x1, y1], [x2, y2]] (thanks @ShimShamSam #2360)
  • Text has a new property maxLines which is the maximum number of lines to be shown for wrapped text. If set to 0 (the default) there is limit. This prevents wrapped text from overflowing on a fixed layout (thanks @slashman #2410)
  • outOfCameraBoundsKill is a new boolean property that all Game Objects with the InWorld component has. If autoCull and this property are both true then the Object will be automatically killed if it leaves the camera bounds (thanks @jakewilson #2402)
  • Group.getByName searches the Group for the first instance of a child with the nameproperty matching the given argument. Should more than one child have the same name only the first instance is returned.
  • BitmapData has a new property frameData which is a Phaser.FrameData container instance. It contains a single Frame by default, matching the dimensions of the entire BitmapData, but can be populated with additional frames should you wish to create animations from dynamic BitmapData textures.
  • FrameData.destroy will nullify the local arrays used to contain Frame instances.
  • SoundManager.muteOnPause is a new boolean that allows you to control if the Sound system gets muted automatically when a Phaser game pauses, such as when it loses focus. You may need to set this to false if you wish to control the audio system from outside of your Phaser game, i.e. from DOM buttons or similar (#2382)
  • You can now pass a TilemapLayer as a Texture to a TileSprite. A limitation of this is that if you pass it to a TileSprite it will make a fill pattern from the TilemapLayer at that instant it's passed, and it won't keep track of the layer in future should it update (thanks @jdnichollsc #1989)
  • Camera has a new property: lerp. This is a Point object, that allows you to control the amount of horizontal and vertical smoothing to be applied to the camera when it tracks a Sprite. It works both with and without deadzones, and is turned off by default. Set it to low values such as 0.1 for really smooth motion tracking (thanks to @WombatTurkey for the idea of adding this)
  • Camera.shake is a new function that creates a camera shake effect. You can specify the intensity, duration and direction of the effect. You can also set if it should shake the camera out of bounds or not.
  • Camera.flash is a new function that makes the camera 'flash' over the top of your game. It works by filling the game with the solid fill color specified, and then fading it away to alpha 0 over the duration given. This is great for things like hit effects. You can listen for the Camera.onflashComplete Signal.
  • Camera.fade is a new function that makes the camera fade to the color given, over the course of the duration specified. This is great for things like transitioning from one State to another. You can listen for the Camera.onFadeComplete Signal.
  • Camera.resetFX resets any active FX, such as a fade or flash and immediately clears it. Useful for calling after a fade in order to remove the fade from the Stage.
  • Phaser.Camera.ENABLE_FX is a const that controls if the Camera FX are available or not. It's true by default, but if you set it to false before boot then it won't create the Graphics object required to process the effects.
  • The Arcade Physics Body has two new properties: left and top. These are the same as Body.x and Body.y but allow you to pass the Body to geometry level functions such as Circle.contains.
  • World.separate has been optimized to cut down on the number of calls to intersectfrom 3 calls per Game Object collision check, to 2. So if you were colliding 50 sprites it will reduce the call count from 150 to 100 per frame. It also reduces the calls made to seperateX and seperateY by the same factor.
  • Two immovable bodies would never set their overlap data, even if an overlap only check was being made. As this is useful data to have this has been changed. Two immovable bodies will still never separate from each other, but they will have their overlapX and overlapY properties calculated now.
  • P2.Body.offset is now used and applied to the Sprite position during rendering. The values given are normal pixel values, and offset the P2 Body from the center of the Sprite (thanks @Mourtz #2430)
Updates
  • TypeScript definitions fixes and updates (thanks @jamesgroat @kiswa)
  • Docs typo fixes (thanks @thiagojobson @hayesmaker @EJanuszewski)
  • Removed a console.log from the TilingSprite generator.
  • Sound.position can no longer become negative, meaning calls to AudioContextNode.start with negative position offsets will no longer throw errors (thanks @Weedshaker #2351 #2368)
  • The default state of the internal property _boundDispatch in Phaser.Signal is now false, which allows for use of boundDispatches (thanks @alvinlao #2346)
  • The Tiled parser only supports uncompressed layer data. Previously it would silently fail, now it detects if layer compression is used and displays a console warning instead (thanks @MannyC #2413)
  • The Tiled parser now removes the encoding parameter so that a subsequent process doesn't try to decode the data again (thanks @MannyC #2412)
  • Ensure a parent container is a Group before removing from its hash (thanks @rblopes #2397)
  • The Game Object Input Handler now checks to see if the Object was destroyed during the onInputDown phase, and bails out early if so (thanks @zeterain #2394)
  • The Destroy component will now call TweenManager.removeFrom, removing any active tweens from the TweenManager upon the Game Objects destructions (thanks @PokemonAshLovesMyTurkeyAndILikeYouTwo #2408)
  • Tween.update will now return false (flagging the Tween for destruction) should the Tween.target property every become falsey. This can happen if the object the Tween was tracking is destroyed, nulled or generally removed.
  • TweenData.repeatTotal is a new property that keeps track of the total number of times the Tween should repeat. If TweenData.start is called, as a result of the Tween repeatCount being > 0 then the child tween resets its total before re-starting.
  • The Debug canvas now listens for the ScaleManager.onSizeChange signal and resizes itself accordingly when running under WebGL. This means if your game size changes the Debug canvas won't be clipped off (thanks @francisberesford #1919)
  • Camera.follow now uses the Targets world property to seed the camera coordinates from, rather than its local position. This means Sprites that are members of offset Groups, or transformed display lists, should now be followed more accurately (thanks @rbozan #2106)
  • PluginManager.destroy is now called by Game.destroy.
  • Game.forceSingleUpdate is now true by default.
  • Video now uses MediaStreamTrack.stop() instead of MediaStream.stop() where possible, as the later is now deprecated in some browsers (thanks @stoneman1 #2371)
  • The Physics Manager will now throw a console warning if you try to enable a physics body using an unknown physics engine type (thanks @jakewilson #2415)
  • The Tileset class will tell you the name of the tileset image throwing the uneven size error (thanks @jakewilson #2415)
  • Emitter.start when used with a false explode parameter would cumulatively add particles to the current total. With quantity 10 the first call would emit 10 particles, the next 20, and so on. Calls to start will now reset the quantity each time. This is a behavior change from earlier versions, so if you relied on the old way please account for it in your code (thanks @BdR76 #2187)
  • You can now pass in your own Canvas element to Phaser and it will use that instead of creating one itself. To do so you must pass a Game Configuration object to Phaser when you instantiate it, and set the canvas property of the config object to be the DOM element you wish to use, i.e.: { canvas: document.getElementById('yourCanvas') }(thanks @Friksel #2311)
  • When loading Video with the asBlob argument set it now uses a 'blob' type for the XHR loader, and doesn't cast the resulting file as a Blob upon load. This fixes loading videos as blobs on Chrome for Android (thanks @JuCarr #2433)
  • When the Loader loads audio via the Audio tag, instead of Web Audio, it used to use Phaser.GAMES[_this.game.id].load as the callback handler, which would stop it from working if you had multiple Loaders set-up within Phaser. It now uses a local reference to _this instead (thanks @SBCGames #2435)
Bug Fixes
  • The mouseoutglobal event listener wasn't removed when the game was destroyed (thanks @stoneman1 #2345 #2344 #2342)
  • Fixed issue with IE crashing on this.context.close in the Sound Manager (thanks @stoneman1 #2349)
  • Phaser.World.centerX and Phaser.World.centerY only worked if the bounds had an origin of 0, 0. They now take into account the actual origin (thanks @fillmoreb #2353)
  • SoundManager.destroy now validates that context.close is a valid function before calling it (thanks @brianbunch #2355)
  • SoundManager.destroy doesn't close the context if it's being stored in PhaserGlobal (thanks @brianbunch #2356)
  • Fix typo in p2 BodyDebug.componentToHex that made most debug bodies appear reddish in color (thanks @englercj #2381)
  • Previously when a sprite was tinted and a new texture was loaded then the tint did not apply to the texture and the old tinted texture was used (thanks @CptSelewin #2383)
  • Negative lineSpacing in Text objects will no longer crop the bottom pixels off lines of text (thanks @gaelenh #2379 #2374)
  • BitmapData.copy, and by extension draw, drawFull, drawGroup, etc, would incorrectly handle drawing a tinted Sprite if it was using a frame from a texture atlas (thanks @PhaserDebugger #2405)
  • Text that used fonts which had numbers in their names wouldn't be correctly rendered unless you explicitly set the font property after creation. You can now pass font names with numbers in them as the font style object correctly (thanks @And-0 #2390)
  • Tween.update wouldn't dispatch an onLoop signal for Tweens with just one child, such as those created via Tween.to with -1 as the repeat value (thanks @ForgeableSum #2407)
  • Arcade.Body's speed property was only set when the body moved, it now updates regardless (thanks @mark-henry #2417)
  • Camera.position would return the view rectangles centerX/Y coordinates, instead of view.x/y (which is what Camera.x/y returns), so it has been updated to return view.x/y instead (thanks @kamparR #2120)
  • Passing a BitmapData to a TileSprite as a texture would fail if the BitmapData had not been previously added to the cache. It now uses the new frameData property (thanks @mzamateo @lucap86 #2380)
  • When setting a global volume for the SoundManager it would previously incorrectly calculate the volumes of AudioTag based Sound objects that were not played at volume 1. The new approach uses Sound.updateGlobalVolume which adjusts the Sound volume to be a percentage of the global volume. So if the global volume is 0.5 and the Sound volume is 0.5, the Sound will play with an actual volume of 0.25 (thanks @VitaZheltyakov #2325)
  • Sound.play when using an AudioTag would ignore the muted state of the SoundManager and play regardless. It now checks the SoundManager.mute state on play, and sets the volume accordingly (thanks @brianbunch #2139)
  • Graphics objects can now have a Physics Body directly attached to them, where-as before it would throw an error due to a lack of anchor property (thanks @NLilley #2400)
  • A Game Object with fixedToCamera = true that was then set for Input, and enabled for dragging from its center (input.enableDrag(true)) would throw an error upon being dragged (thanks @solusipse #2367)
  • P2.World.updateBoundsCollisionGroup wouldn't use the boundsCollisionGroup mask if you passed true as the argument, only if it was left undefined.
  • P2.World.updateBoundsCollisionGroup didn't set the _boundsOwnGroup private var, meaning the World.setBounds method wasn't able to restore previously set collision masks automatically (thanks @jmp909 #2183)
  • P2.World.setBounds has been re-written completely. If the World is resized it no longer removes the P2 body instances and re-creates them. Instead it checks to see which walls are required and then just moves the position of the shapes instead, or updates them, or creates or destroys them as required. This is far more efficient, especially in a game which sees a lot of world bounds changes (i.e. resizes responsively in browser)
  • BitmapText would throw an error if you passed in a number as the text property to the constructor. It worked if you used the text accessor directly because it cast the value to a string, but the constructor missed out this step (thanks @lewispollard #2429)
  • Dragging a Sprite while the camera was moving would slowly cause the Sprite position to become out of sync the further the camera moved. A Sprite being dragged now tracks the camera position during the drag update and adjusts accordingly (thanks @jeroenverfallie #1044)
Pixi Updates

Please note that Phaser uses a custom build of Pixi and always has done. The following changes have been made to our custom build, not to Pixi in general.

  • DisplayObjectContainer.getLocalBounds destroys the worldTransforms on children until the next stage.updateTransform() call. This can make a number of things break including mouse input if width, height or getLocalBounds methods are called inside of an update or preUpdate method. This is now fixed in our Pixi build (thanks @st0nerhat #2357)
  • PIXI.CanvasRenderer.resize now applies the renderSession.smoothProperty to the Canvas context when it resizes. This should help with unwanted canvas smoothing (thanks @sergey7c4 #2395 #2317)

19. April 2016

 

A couple days ago Phaser 2.4.7 RC1 was released.  This is one of the final releases for Phaser 2.x as focus shifts to Phaser 3 (“Lazer”).  Phaser is an excellent and feature complete game engine for HTML5 game development that I covered in this tutorial series.  While Phaser 2.x is winding down toward maintenance mode, this release adds several new features:

New Features
  • Added P2.Body.thrustLeft which will move the Body to the left by the speed given (thanks James Pryor)
  • Added P2.Body.thrustRight which will move the Body to the right by the speed given (thanks James Pryor)
  • Polygon now takes an array of arrays as a new type when constructing it: [[x1, y1], [x2, y2]] (thanks @ShimShamSam #2360)

It works both with and without deadzones, and is turned off by default. Set it to low values such as 0.1 for really smooth motion tracking (thanks to @WombatTurkey for the idea of adding this)
  • Camera.shake is a new function that creates a camera shake effect. You can specify the intensity, duration and direction of the effect. You can also set if it should shake the camera out of bounds or not.
  • Camera.flash is a new function that makes the camera 'flash' over the top of your game. It works by filling the game with the solid fill color specified, and then fading it away to alpha 0 over the duration given. This is great for things like hit effects. You can listen for the Camera.onflashComplete Signal.
  • Camera.fade is a new function that makes the camera fade to the color given, over the course of the duration specified. This is great for things like transitioning from one State to another. You can listen for the Camera.onFadeComplete Signal.
  • Camera.resetFX resets any active FX, such as a fade or flash and immediately clears it. Useful for calling after a fade in order to remove the fade from the Stage.
  • Phaser.Camera.ENABLE_FX is a const that controls if the Camera FX are available or not. It's true by default, but if you set it to false before boot then it won't create the Graphics object required to process the effects.
  • The Arcade Physics Body has two new properties: left and top. These are the same as Body.x and Body.y but allow you to pass the Body to geometry level functions such as Circle.contains.
  • World.separate has been optimized to cut down on the number of calls to intersect from 3 calls per Game Object collision check, to 2. So if you were colliding 50 sprites it will reduce the call count from 150 to 100 per frame. It also reduces the calls made to seperateX and seperateY by the same factor.
  • Two immovable bodies would never set their overlap data, even if an overlap only check was being made. As this is useful data to have this has been changed. Two immovable bodies will still never separate from each other, but they willhave their overlapX and overlapY properties calculated now.
  • P2.Body.offset is now used and applied to the Sprite position during rendering. The values given are normal pixel values, and offset the P2 Body from the center of the Sprite (thanks @Mourtz #2430)
Updates
  • TypeScript definitions fixes and updates (thanks @jamesgroat)
  • Docs typo fixes (thanks @thiagojobson @hayesmaker @EJanuszewski)
  • Removed a console.log from the TilingSprite generator.
  • Sound.position can no longer become negative, meaning calls to AudioContextNode.start with negative position offsets will no longer throw errors (thanks @Weedshaker #2351 #2368)
  • The default state of the internal property _boundDispatch in Phaser.Signal is now false, which allows for use of boundDispatches (thanks @alvinlao #2346)
  • The Tiled parser only supports uncompressed layer data. Previously it would silently fail, now it detects if layer compression is used and displays a console warning instead (thanks @MannyC #2413)
  • The Tiled parser now removes the encoding parameter so that a subsequent process doesn't try to decode the data again (thanks @MannyC #2412)
  • Ensure a parent container is a Group before removing from its hash (thanks @rblopes #2397)
  • The Game Object Input Handler now checks to see if the Object was destroyed during the onInputDown phase, and bails out early if so (thanks @zeterain #2394)
  • The Destroy component will now call TweenManager.removeFrom, removing any active tweens from the TweenManager upon the Game Objects destructions (thanks @PokemonAshLovesMyTurkeyAndILikeYouTwo #2408)
  • Tween.update will now return false (flagging the Tween for destruction) should the Tween.target property every become falsey. This can happen if the object the Tween was tracking is destroyed, nulled or generally removed.
  • TweenData.repeatTotal is a new property that keeps track of the total number of times the Tween should repeat. If TweenData.start is called, as a result of the Tween repeatCount being > 0 then the child tween resets its total before re-starting.
  • The Debug canvas now listens for the ScaleManager.onSizeChange signal and resizes itself accordingly when running under WebGL. This means if your game size changes the Debug canvas won't be clipped off (thanks @francisberesford #1919)
  • Camera.follow now uses the Targets world property to seed the camera coordinates from, rather than its local position. This means Sprites that are members of offset Groups, or transformed display lists, should now be followed more accurately (thanks @rbozan #2106)
  • PluginManager.destroy is now called by Game.destroy.
  • Game.forceSingleUpdate is now true by default.
  • Video now uses MediaStreamTrack.stop() instead of MediaStream.stop() where possible, as the later is now deprecated in some browsers (thanks @stoneman1 #2371)
  • The Physics Manager will now throw a console warning if you try to enable a physics body using an unknown physics engine type (thanks @jakewilson #2415)
  • The Tileset class will tell you the name of the tileset image throwing the uneven size error (thanks @jakewilson #2415)
  • Emitter.start when used with a false explode parameter would cumulatively add particles to the current total. With quantity 10 the first call would emit 10 particles, the next 20, and so on. Calls to start will now reset the quantity each time. This is a behavior change from earlier versions, so if you relied on the old way please account for it in your code (thanks @BdR76 #2187)
  • You can now pass in your own Canvas element to Phaser and it will use that instead of creating one itself. To do so you must pass a Game Configuration object to Phaser when you instantiate it, and set the canvas property of the config object to be the DOM element you wish to use, i.e.: { canvas: document.getElementById('yourCanvas') } (thanks @Friksel #2311)
  • When loading Video with the asBlob argument set it now uses a 'blob' type for the XHR loader, and doesn't cast the resulting file as a Blob upon load. This fixes loading videos as blobs on Chrome for Android (thanks @JuCarr #2433)
  • When the Loader loads audio via the Audio tag, instead of Web Audio, it used to use Phaser.GAMES[_this.game.id].loadas the callback handler, which would stop it from working if you had multiple Loaders set-up within Phaser. It now uses a local reference to _this instead (thanks @SBCGames #2435)
Bug Fixes
  • The mouseoutglobal event listener wasn't removed when the game was destroyed (thanks @stoneman1 #2345 #2344 #2342)
  • Fixed issue with IE crashing on this.context.close in the Sound Manager (thanks @stoneman1 #2349)
  • Phaser.World.centerX and Phaser.World.centerY only worked if the bounds had an origin of 0, 0. They now take into account the actual origin (thanks @fillmoreb #2353)
  • SoundManager.destroy now validates that context.close is a valid function before calling it (thanks @brianbunch #2355)
  • SoundManager.destroy doesn't close the context if it's being stored in PhaserGlobal (thanks @brianbunch #2356)
  • Fix typo in p2 BodyDebug.componentToHex that made most debug bodies appear reddish in color (thanks @englercj #2381)
  • Previously when a sprite was tinted and a new texture was loaded then the tint did not apply to the texture and the old tinted texture was used (thanks @CptSelewin #2383)
  • Negative lineSpacing in Text objects will no longer crop the bottom pixels off lines of text (thanks @gaelenh #2379 #2374)
  • BitmapData.copy, and by extension draw, drawFull, drawGroup, etc, would incorrectly handle drawing a tinted Sprite if it was using a frame from a texture atlas (thanks @PhaserDebugger #2405)
  • Text that used fonts which had numbers in their names wouldn't be correctly rendered unless you explicitly set the font property after creation. You can now pass font names with numbers in them as the font style object correctly (thanks @And-0 #2390)
  • Tween.update wouldn't dispatch an onLoop signal for Tweens with just one child, such as those created via Tween.to with -1 as the repeat value (thanks @ForgeableSum #2407)
  • Arcade.Body's speed property was only set when the body moved, it now updates regardless (thanks @mark-henry #2417)
  • Camera.position would return the view rectangles centerX/Y coordinates, instead of view.x/y (which is what Camera.x/y returns), so it has been updated to return view.x/y instead (thanks @kamparR #2120)
  • Passing a BitmapData to a TileSprite as a texture would fail if the BitmapData had not been previously added to the cache. It now uses the new frameData property (thanks @mzamateo @lucap86 #2380)
  • When setting a global volume for the SoundManager it would previously incorrectly calculate the volumes of AudioTag based Sound objects that were not played at volume 1. The new approach uses Sound.updateGlobalVolume which adjusts the Sound volume to be a percentage of the global volume. So if the global volume is 0.5 and the Sound volume is 0.5, the Sound will play with an actual volume of 0.25 (thanks @VitaZheltyakov #2325)
  • Sound.play when using an AudioTag would ignore the muted state of the SoundManager and play regardless. It now checks the SoundManager.mute state on play, and sets the volume accordingly (thanks @brianbunch #2139)
  • Graphics objects can now have a Physics Body directly attached to them, where-as before it would throw an error due to a lack of anchor property (thanks @NLilley #2400)
  • A Game Object with fixedToCamera = true that was then set for Input, and enabled for dragging from its center (input.enableDrag(true)) would throw an error upon being dragged (thanks @solusipse #2367)
  • P2.World.updateBoundsCollisionGroup wouldn't use the boundsCollisionGroup mask if you passed true as the argument, only if it was left undefined.
  • P2.World.updateBoundsCollisionGroup didn't set the _boundsOwnGroup private var, meaning the World.setBoundsmethod wasn't able to restore previously set collision masks automatically (thanks @jmp909 #2183)
  • P2.World.setBounds has been re-written completely. If the World is resized it no longer removes the P2 body instances and re-creates them. Instead it checks to see which walls are required and then just moves the position of the shapes instead, or updates them, or creates or destroys them as required. This is far more efficient, especially in a game which sees a lot of world bounds changes (i.e. resizes responsively in browser)
  • BitmapText would throw an error if you passed in a number as the text property to the constructor. It worked if you used the text accessor directly because it cast the value to a string, but the constructor missed out this step (thanks @lewispollard #2429)
  • Dragging a Sprite while the camera was moving would slowly cause the Sprite position to become out of sync the further the camera moved. A Sprite being dragged now tracks the camera position during the drag update and adjusts accordingly (thanks @jeroenverfallie #1044)

Phaser, the cross platform HTML5 based game library I covered in this tutorial series, just released version 2.4.5.

From the release:

Phaser 2.4.5 is our first release in 2016 and represents several months of fixes and optimizations. As a point release it's a safe update from a previous 2.4 build, but as always please test first before upgrading, and be sure to skim through the extensive change log. There are some great new features including Dolby Digital sound support, loads of updates to Pixi and a new Webpack bundle.

  • 14 new features including Dolby Digital audio support and advanced Text wrapping
  • 30 updates including replacing PolyK with EarCut, Tilemap updates and lots of TypeScript and JSDoc updates.
  • 31 bug fixes including OS X Chrome right-click issues, Sprite mouse over, Tween event order, Loader queue fixes and more.
  • 10 updates to our build of Pixi including CanvasPool tweaks, fixing generateTexture bounds calculations and Filter Texture and GL Viewport fixes.

Due to on-going development of Lazer (previously known as Phaser 3) Phaser is soon to enter the LTS (long-term support) stage of its life. This is when we impose a feature freeze, locking the API down and responding only to bugs. This is a necessary step to allow us to focus on Lazer while still ensuring Phaser is given the support it deserves. Thousands of developers use Phaser and we've no intention of ignoring that. However with the release of 2.4.5 we will now be moderating issues opened on GitHub to this effect.
