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.

Over 1000 github stars! Wow! The latest release of Phaser represents another hard months work by the development team and the community at large. We've had some great contributions and have not let-up the pace of innovating and pushing Phaser forward. As we march towards the end of 2013 we do so knowing that with every passing month more and more developers are using Phaser, and more games are being made. All while it is getting stronger with each release.
Our plan is to end 2013 with one final point release (1.1.4 - "Kandor") and then we'll start planning out the features we wish to see in version 1.2 in the New Year.
As always 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 back then: 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.
We have a new [Getting Started Guide](http://phaser.io/getting-started-js.php) which covers all you need to begin developing games with Phaser. From setting up a web server to picking an IDE. If you're new to HTML5 game development (or are coming from another language like AS3) then we recommend starting there.
There is a comprehensive [How to Learn Phaser](http://gamedevelopment.tutsplus.com/articles/how-to-learn-the-phaser-html5-game-engine--gamedev-13643) guide on the GameDevTuts+ site which is well worth reading through.
There is also this great [Un-official Getting Started Guide](http://www.antonoffplus.com/coding-an-html5-game-for-30-minutes-or-an-introduction-to-the-phaser-framework) which is well worth running through as well.
* TilemapLayers are now created via the Tilemap object itself: map.createLayer(x, y, width, height, tileset, layer, group) and no longer via the GameObjectFactory.
* TilemapLayers now have debug and debugAlpha values, this turns on the drawing of the collision edges (very handy for debugging, as the name implies!)
* You can now load any binary file via the Loader: game.load.binary(key, url, callback) - the optional callback allows for post-load processing before entering the Cache.
* Tweens can now work with relative + and - values. You can do: `tween(sprite).to( { x: '+400' })` and it will add 400 to the current sprite.x value, or '-400'.
* Loader.progressFloat contains the actual non-rounded progress value, where-as Loader.progress contains a rounded value. Use progressFloat if you've > 100 files to load.
* Most of the GameObjectFactory functions now have a group parameter, so you can do: game.add.sprite(x, y, frame, frameName, group) rather than defaulting to the World group.
* Group.countLiving and countDead used to return -1 if the Group was empty, but now return 0.
* Text can now be fixedToCamera, updated world/fixed to camera example to show this.
* Pointer used to un-pause a paused game every time it was clicked/touched (this avoided some rogue browser plugins). Now only happens if Stage.disableVisibilityChange is true.
* You can now collide a group against itself, to have all children collide, and bodies won't check against themselves (thanks cocoademon)
* RenderTexture.render / renderXY has a new parameter: renderHidden, a boolean which will allow you to render Sprites even if their visible is set to false.
* Cache.getImageKeys returned __missing in the array, now excluded.
* Fixed Group.scale so you can now scale a Group directly.
* Removed World.scale as it was preventing Group.scale from working - you can still scale the world, but you'll need to factor in Input changes yourself.
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 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 200 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.
The examples need to be run through a local web server (in order to avoid file access permission errors from your browser). You can use your own web server, or start the included web server using grunt.
Using a locally installed web server browse to the examples folder:
Alternatively in order to start the included web server, after you've cloned the repo, run `npm install` to install all dependencies, then `grunt connect` to start a local server. After running this command you should be able to access your local webserver at `http://127.0.0.1:8000`. Then browse to the examples folder: `http://127.0.0.1:8000/examples/index.html`
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. When running under WebGL Phaser now supports shaders, allowing for some incredible in-game effects. 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 and JavaScrtip files - 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 mobile 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:
* 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.
