Phaser is a fast, free and fun open source game framework for making desktop and mobile browser HTML5 games. It uses [Pixi.js](https://github.com/GoodBoyDigital/pixi.js/) internally for fast 2D Canvas and WebGL rendering.
It's staggering to think just how much has been achieved in the short time Phaser has been alive. We've implemented literally hundreds of bug fixes and updates, thanks to the effort the community puts in to reporting issues they find. Exciting new features have been merged into the core and we revisited old ones and pimped them out. We also completely overhauled the Examples Suite, removed the requirement for PHP, rebuilt it and filled it with over 150 examples to dig in and learn from. And more importantly we've got our first pass at the API docs ready too.
There is still more to be done of course. The API docs, while a good start, are lacking in places and still need to be backed up with a proper comprehensive manual. And we desperately need to write some 'best practises' and 'getting started' tutorials too. But we hope you appreciate the amount of effort that has been put in by the team so far.
There are many exciting new features and tweaks in this build that we felt it warranted a proper point release, hence the shift to version 1.1. Because of several core changes games that were in development in a 1.0.x version of Phaser may need refactoring for 1.1, but we feel those changes have helped the framework grow and mature as a whole.
As before we offer a heart-felt "Thank you!" to everyone who has encouraged us along the way. To those of you who worked with Phaser during its various incarnations, and who released full games with it despite there being zero API documentation available: you are our heroes. It's your kind words and enthusiasm that has kept us going.
Phaser is everything we ever wanted from an HTML5 game framework. It powers all of our client work in build today and remains our single most important product, and we've only just scratched the surface of what we have planned for it.
* Updated: State functions (preload, update, render, etc) are now passed the current game as a parameter (thanks beeglebug)
* Updated: If your game is running in Canvas (not WebGL) you can now set Stage.backgroundColor to rgba style CSS strings, allowing for semi-transparent game backgrounds.
* Updated: event.preventDefault() has been added to all Mouse event handlers.
* Updated: Sprite.deltaX/Y removed due to non-use. prevX/Y values moved to Sprite._cache.prevX/Y.
* Updated: Due to missing extends parameter the Sprite prototype was picking up functions from classes it never meant to (Button, TilemapLayer), now fully isolated.
* Added Keyboard.addKey() which creates a new Phaser.Key object that can be polled for updates, pressed states, etc. See the 2 new examples showing use.
* Added Keyboard.createCursorKeys() which creates an object with 4 Key objects inside it mapped to up, down, left and right. See the new example in the input folder.
* Added Body.skipQuadTree boolean for more fine-grained control over when a body is added to the World QuadTree.
* Re-implemented Angular Velocity and Angular Acceleration on the Sprite.body and created 2 new examples to show use.
* Added Sprite.fixedToCamera boolean. A Sprite that is fixed to the camera doesn't move with the world, but has its x/y coordinates relative to the top-left of the camera.
* Added killOnComplete parameter to Animation.play. Really useful in situations where you want a Sprite to animate once then kill itself on complete, like an explosion effect.
* On a busy page it's possible for the game to boot with an incorrect stage offset x/y which can cause input events to be calculated wrong. A new property has been added to Stage to combat this issue: Stage.checkOffsetInterval. By default it will check the canvas offset every 2500ms and adjust it accordingly. You can set the value to 'false' to disable the check entirely, or set a higher or lower value. We recommend that you get the value quite low during your games preloader, but once the game has fully loaded hopefully the containing page will have settled down, so it's probably safe to disable the check entirely.
* Added Rectangle.floorAll to floor all values in a Rectangle (x, y, width and height).
What's changed:
* Renamed Phaser.Text.text to Phaser.Text.content to avoid conflict and overwrite from Pixi local var.
* Renamed Phaser.Text.style to Phaser.Text.font to avoid conflict and overwrite from Pixi local var.
* Phaser.Button now sets useHandCursor to true by default.
* Change: When you start a new State all active tweens are now purged.
* When the game boots it will now by default disable user-select and touch action events on the game canvas.
* Moved LinkedList.dump to Debug.dumpLinkedList(list)
* Phaser.Animation.Frame is now Phaser.Frame
* Phaser.Animation.FrameData is now Phaser.FrameData
* Phaser.Animation.Parser is now Phaser.AnimationParser (also the file has renamed from Parser.js to AnimationParser.js)
* Phaser.Loader.Parser is now Phaser.LoaderParser (also the file has renamed from Parser.js to LoaderParser.js)
* Change: We've removed the scrollFactor property from all Game Objects. Sorry, but the new Camera system doesn't work with it and it caused all kinds of issues anyway. We will sort out a replacement for it at a later date.
* Change: World now extends Phaser.Group. As a result we've updated GameObjectFactory and other classes that linked to it. If you have anywhere in your code that used to reference world.group you can just remove 'group' from that. So before, world.group.add() is now just world.add().
* Change: The Camera has been completely revamped. Rather than adjusting the position of all display objects (bad) it now just shifts the position of the single world container (good!), this is much quicker and also stops the game objects positions from self-adjusting all the time, allowing for them to be properly nested with other containers.
* Made Sprite.body optional and added in checks, so you can safely null the Sprite body object if using your own physics system and not impact rendering.
* Moved the Camera update checks to World.postUpdate, so all the sprites get the correct adjusted camera position.
* The default Game.antialias value is now 'true', so graphics will be smoothed automatically in canvas. Disable it via the Game constructor or Canvas utils.
* Phaser.Group now automatically calls updateTransform on any child added to it (avoids temp. frame glitches when new objects are rendered on their first frame).
* Complete overhaul of Physics.Arcade.Body - now significantly more stable and faster too.
* Updated ArcadePhysics.separateX/Y to use new body system - much better results now.
* Added World.postUpdate - all sprite position changes, as a result of physics, happen here before the render.
* Added Animation.paused - can be set to true/false.
* Added support for Body.maxVelocity (thanks cocoademon)
* InputHandler now creates the _pointerData array on creation and populates with one empty set of values, so pointerOver etc all work before a start call.
* Removed the callbackContext parameter from Group.callAll because it's no longer needed.
* Updated Group.forEach, forEachAlive and forEachDead so you can now pass as many parameters as you want, which will all be given to the callback after the child.
* Updated build script so it can be run from the command-line and includes UMD wrappers (thanks iaincarsberg)
* World.randomX/Y now returns values anywhere in the world.bounds range (if set, otherwise 0), including negative values.
* Updated InputHandler to use Math.round rather than Math.floor when snapping an object during drag.
* If you didn't provide the useNumericIndex parameter then AnimationManager.add will set the value by looking at the datatype of the first element in the frames array.
* Group.create now sets the visible and alive properties of the Sprite to the same value as the 'exists' parameter.
* World.randomX/Y now works with negative World.bounds values.
* Tweens .to will now always return the parent (thanks powerfear)
* You can now pass a PIXI.Texture to Sprite (you also need to pass a Phaser.Frame as the frame parameter) but this is useful for Sprites sharing joint canvases.
* Group.alpha is now exposed publically and changes the Group container object (not the children directly, who can still have their own alpha values)
* Device.webGL uses new inspection code to accurately catch more webGL capable devices.
* Debug.renderSpriteBody updated to use a the new Sprite.Body.screenX/Y properties.
* Additional checks added to AnimationManager.frame/frameName on the given values.
* You can now null a Sprite.crop and it will clear down the crop rect area correctly.
* Animation.generateFrameNames can now work in reverse, so the start/stop values can create frames that increment or decrement respectively.
* Loader updated to use xhr.responseText when loading json, csv or text files. xhr.response is still used for Web Audio binary files (thanks bubba)
* Input.onDown and onUp events now dispatch the original event that triggered them (i.e. a MouseEvent or TouchEvent) as the 2nd parameter, after the Pointer (thanks rezoner)
* Updated Sprite.crop significantly. Values are now cached, stopping constant Texture frame updates and you can do sprite.crop.width++ for example (thanks haden)
* Change: Sprite.crop needs to be enabled with sprite.cropEnabled = true.
* QuadTree bug found in 1.0.5 now fixed. The QuadTree is updated properly now using localTransform values.
* Fixed the Bounce.In and Bounce.InOut tweens (thanks XekeDeath)
* Fixed an issue in Animation.update where if the game was paused it would get an insane delta timer throwing a uuid error.
* Added PixiPatch.js to patch in a few essential features until Pixi is updated.
* Fixed issue in Animation.play where the given frameRate and loop values wouldn't overwrite those set on construction.
* Fixed small bug stopping Tween.pause / resume from resuming correctly when called directly.
* Fixed an issue where Tweens.removeAll wasn't clearing tweens in the addition queue.
* Fixed Particle Emitters when using Emitter width/height (thanks XekeDeath)
* Made animation looping more robust when skipping frames (thanks XekeDeath)
* Fix for incorrect new particle positioning (issue #73) (thanks cottonflop)
* Fixed issue in Sound.play where if you gave a missing marker it would play the whole sound sprite instead.
* Button.setFrames will set the current frame based on the button state immediately.
* Loaded.setPreloadSprite now rounds the width/height values and starts from 1. This fixes canvas draw errors in IE9/10 and Firefox.
* Fixed issue causing Keyboard.justPressed to always fire (thanks stemkoski)
* Fixed bug in LinkedList#remove that could cause first to point to a dead node (thanks onedayitwillmake)
* Fixed Cache.addDefaultImage so the default image works in Canvas as well as WebGL. Updated to a new image (32x32 black square with green outline)
* Fixed a bug in the Sprite transform cache check that caused the skew/scale cache to get constantly invalidated - now only updates as needed, significant performance increase!
* Fixed typo in StageScaleMode so it's not pageAlignVeritcally any longer, but pageAlignVertically.
* Fixed issue in Group.countLiving / countDead where the value was off by one (thanks mjablonski)
* Fixed issue with a jittery Camera if you moved a Sprite via velocity instead of x/y placement.
* Fixed the RandomDataGenerator.sow method so if you give in the same seed you'll now get the same results (thanks Hsaka)
* Fixed Issue #101 (Mouse Button 0 is not recognised, thanks rezoner)
* Fixed an issue where creating an animation with just one frame with an index of zero would cause a UUID error (thanks SYNYST3R1)
* Fixed Rectangle.union (thanks andron77)
* Fixed Sound.resume so it now correctly resumes playback from the point it was paused (fixes issue 51, thanks Yora).
* Fixed issue 105 where a dragged object that was destroyed would cause an Input error (thanks onedayitwillmake)
* Fixed Issue 111 - calling Kill on a Phaser.Graphics instance causes error on undefined events.
* Game.destroy will now stop the raf from running as well as close down all input related event listeners (issue 92, thanks astrism)
A Grunt script has been provided that will build Phaser from source as well as the examples. Run `grunt` in the phaser folder for a list of command-line options.
Games created with Phaser require a modern web browser that supports the canvas tag. This includes Internet Explorer 9+, Firefox, Chrome, Safari and Opera. It also works on mobile web browsers including stock Android 2.x browser and above and iOS5 Mobile Safari and above.
For developing with Phaser you can use either a plain-vanilla JavaScript approach or [TypeScript](https://typescript.codeplex.com/) using the provided TypeScript definitions file. We made no assumptions about how you like to code your games, and were careful not to impose any form of class/inheritance/structure upon you.
Phaser uses both a Canvas and WebGL renderer internally and can automatically swap between them based on browser support. This allows for lightning fast rendering across Desktop and Mobile. Phaser uses and contributes towards the excellent Pixi.js library for rendering.
We've made the loading of assets as simple as one line of code. Images, Sounds, Sprite Sheets, Tilemaps, JSON data, XML - all parsed and handled automatically, ready for use in game and stored in a global Cache for Sprites to share.
Phaser ships with our Arcade Physics system. An extremely light-weight AABB physics library perfect for low-powered devices and fast collision response. Control velocity, acceleration, bounce, drag and full collision and separation control.
Sprites are the life-blood of your game. Position them, tween them, rotate them, scale them, animate them, collide them, paint them onto custom textures and so much more!
Sprites also have full Input support: click them, touch them, drag them around, snap them - even pixel perfect click detection if needed.
Group bundles of Sprites together for easy pooling and recycling, avoiding constant object creation. Groups can also be collided: for example a "Bullets" group checking for collision against the "Aliens" group, with a custom collision callback to handle the outcome.
Phaser supports classic Sprite Sheets with a fixed frame size, Texture Packer and Flash CS6/CC JSON files (both Hash and Array formats) and Starling XML files. All of these can be used to easily create animation for Sprites.
An Arcade Particle system is built-in, which allows you to create fun particle effects easily. Create explosions or constant streams for effects like rain or fire. Or attach the Emitter to a Sprite for a jet trail.
Phaser has a built-in Game World. Objects can be placed anywhere within the world and you've got access to a powerful Camera to look into that world. Pan around and follow Sprites with ease.
Talk to a Phaser.Pointer and it doesn't matter if the input came from a touch-screen or mouse, it can even change mid-game without dropping a beat. Multi-touch, Mouse, Keyboard and lots of useful functions allow you to code custom gesture recognition.
Phaser supports both Web Audio and legacy HTML Audio. It automatically handles mobile device locking, easy Audio Sprite creation, looping, streaming and volume. We know how much of a pain dealing with audio on mobile is, so we did our best to resolve that!
Phaser can load, render and collide with a tilemap with just a couple of lines of code. We support CSV and Tiled map data formats with multiple tile layers. There are lots of powerful tile manipulation functions: swap tiles, replace them, delete them, add them and update the map in realtime.
Phaser has a built-in Scale Manager which allows you to scale your game to fit any size screen. Control aspect ratios, minimum and maximum scales and full-screen support.
We are trying hard to keep the core of Phaser limited to only essential classes, so we built a smart Plugin system to handle everything else. Create your own plugins easily and share them with the community.
Phaser was built specifically for Mobile web browsers. Of course it works blazingly fast on Desktop too, but unlike lots of frameworks mobile was our main focus. If it doesn't perform well on mobile then we don't add it into the Core.
We use Phaser every day on our many client projects. As a result it's constantly evolving and improving and we jump on bugs and pull requests quickly. This is a living, breathing framework maintained by a commercial company with custom feature development and support packages available. We live and breathe HTML5 games.
Although Phaser 1.0 is a brand new release it is born from years of experience building some of the biggest HTML5 games out there. We're not saying it is 100% bug free, but we use it for our client work every day, so issues get resolved <em>fast</em> and we stay on-top of the changing browser landscape.
The 1.1 release was a massive under-taking, but we're really happy with how Phaser is progressing. It's becoming more solid and versatile with each iteration. Here is what's on our road map for future versions:
* Integration with an advanced physics system. We've been experimenting with p2.js but have yet to conclude our research.
* A more advanced Particle system, one that can render to a single canvas (rather than spawn hundreds of Sprites), more advanced effects, etc.
* Massively enhance the audio side of Phaser. Although it does what it does well, it could do with taking more advantage of Web Audio - echo effects, positional sound, etc.
* Comprehensive testing across Firefox OS devices, CocoonJS and Ejecta.
* Integration with third party services like Google Play Game Services and Amazon JS SDK.
* Ability to control DOM elements from the core game and layer them into the game.
* Touch Gestures.
* Virtual d-pad support and also support for the Joypad API.
* Test out packaging with Node-webkit.
* Flash CC HTML5 export integration.
* Game parameters stored in Google Docs.
* More advanced tile map features. Better support for advanced Tiled features and also I want to add full support for DAME tilemaps.
Phaser comes with an ever growing suite of Examples. Personally I feel that we learn better by looking at small refined code examples, so we created over 150 of them and create new ones to test every new feature added. Inside the `examples` folder you'll find the current set. If you write a particularly good example then please send it to us.
You can do this on the Phaser board that is part of the [HTML5 Game Devs forum](http://www.html5gamedevs.com/forum/14-phaser/) or email: rich@photonstorm.com
