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.
[Subscribe to our new Phaser Newsletter](https://confirmsubscription.com/h/r/369DE48E3E86AF1E). We'll email you when new versions are released as well as send you our regular Phaser game making magazine.
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 a great place to learn where to find tutorials, examples and support.
There is also an [un-official Getting Started Guide](http://www.antonoffplus.com/coding-an-html5-game-for-30-minutes-or-an-introduction-to-the-phaser-framework).
* Group now extends PIXI.DisplayObjectContainer, rather than owning a _container property, which makes life a whole lot easier re: nesting and child iteration.
* Removed: Sprite.offset, center, topLeft, topRight, bottomRight, bottomLeft and bounds, as no longer needed internally. Use Sprite.getBounds() to derive them.
* BitmapText has had a bit of an overhaul - the signature for adding a BitmapText has changed to: x, y, font, text, size. See the docs and examples for details.
* After defining tiles that collide on a Tilemap, you need to call Tilemap.generateCollisionData(layer) to populate the physics world with the data required.
* When adding a Group if the parent value is `null` the Group won't be added to the World, so you can add it when ready. If parent is `undefined` it's added by default.
* The Keyboard class has had a complete overhaul. Phaser.Key objects are created automatically, there are fixes against duration and keys reset properly on visibility loss.
* Keyboard.removeKey has been removed. The way the new keyboard manager works means it's no longer required.
* Time.advancedTiming is a new boolean property. If true Time.fps, fpsMin, fpsMax, frames, msMin and msMax will be calculated, otherwise they remain at their defaults.
* Phaser.StageScaleMode has been renamed to ScaleManager and moved from the system folder to the core folder. It's still available under game.scale.
* If your game references the old Phaser.StageScaleMode consts like SHOW_ALL you need to update them to Phaser.ScaleManager, i.e. Phaser.ScaleManager.SHOW_ALL.
* Phaser.Image is a brand new display object perfect for logos, backgrounds, etc. You can scale, rotate, tint, blend an get input events from an Image, but it has no animation, physics body.
* You can now use the hitArea property on Sprites and Image objects. hitArea can be a geometry object (Rectangle, Circle, Polygon, Ellipse) and is used in pointerOver checks.
* Text.inputEnabled allows you to enable all input events over Text objects: dragging, clicking, etc - anything that works on a Sprite works on Text now too.
* Added the new BitmapFont class. This is for rendering retro style fixed-width bitmap fonts into an Image object. It's a texture you can apply to a Sprite/Image.
* Added Cache.updateFrameData which is really useful for swapping FrameData blocks in the cache.
* Tilemap.createCollisionObjects will parse Tiled data for objectgroups and convert polyline instances into physics objects you can collide with in the world.
* Loader can now load JSON files specifically (game.load.json) and they are parsed and stored in the Game.Cache. Retrieve with game.cache.getJSON(key).
* Stage.smoothed allows you to set if sprites will be smoothed when rendered. Set to false if you're using pixel art in your game. Default is true. Works in Canvas and WebGL.
* Sprite.smoothed and Image.smoothed allows you to set per-Sprite smoothing, perfect if you just want to keep a few sprites smoothed (or not)
* StateManager.start can now have as many parameters as you like. The order is: start(key, clearWorld, clearCache, ...) - they are passed to State.init() (NOT create!)
* Game.add.renderTexture now has the addToCache parameter. If set the texture will be stored in Game.Cache and can be retrieved with Cache.getTexture(key).
* Game.add.bitmapData now has the addToCache parameter. If set the texture will be stored in Game.Cache and can be retrieved with Cache.getBitmapData(key).
* We now force IE11 into Canvas mode to avoid a Pixi bug with pre-multiplied alpha. Will remove once that is fixed, sorry, but it's better than no game at all, right? :(
* Loader.setPreloadSprite() will now set sprite.visible = true once the crop has been applied. Should help avoid issues (#430) on super-slow connections.
* Previously if you used Sprite.crop() it would crop all Sprites that shared the same base image. It now takes a local copy of the texture data and crops just that.
* Fixed bug in Math.angleBetween where it was using the coordinates in the wrong order.
* Previously using a Pixel Perfect check didn't work if the Sprite was rotated or had a non-zero anchor point, now works under all conditions + atlas frames.
You can [][koding] and then start editing and previewing code right away using their web based VM development system.
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. A SAT based collision and physics library perfect for low-powered devices and fast collision response. Control velocity, acceleration, bounce, damping and full collision and separation control. As of version 1.1.4 we now support rectangles, circles and polygon collision with full rotation.
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.
[Nadion](https://github.com/jcd-as/nadion) is a set of powerful enhancements for Phaser that makes level building even easier. It includes features such as Trigger, Area, Alarms and Emitters, debug panels, state machines, parallax layer scrolling, 'developer mode' short-cuts and more.
