# Phaser
Phaser is a fast, free and fun open source HTML5 game framework. It uses a custom build of [Pixi.js](https://github.com/GoodBoyDigital/pixi.js/) for WebGL and Canvas rendering across desktop and mobile web browsers. Games can be compiled to iOS, Android and desktop apps via 3rd party tools like Cocoon, Cordova and Electron.
Along with the fantastic open source community Phaser is actively developed and maintained by [Photon Storm Limited](http://www.photonstorm.com). As a result of rapid support and a developer friendly API Phaser is currently one of the [most starred](https://github.com/showcases/javascript-game-engines) game frameworks on GitHub.
Thousands of developers worldwide use it. From indies and multi-national digital agencies to schools and Universities. Each creating their own incredible games. Grab the source and join in the fun!

Handy features include Smart code auto-completion, built-in web server, documentation search, asset management, texture atlas creator, audio sprite creator, asset previews and lots more.
### Game Mechanic Explorer
The [Game Mechanic Explorer](http://gamemechanicexplorer.com) is a great interactive way to learn how to develop specific game mechanics in Phaser. Well worth exploring once you've got your dev environment set-up.
### Mighty Editor - Visual Game Editor
[MightyEditor](http://mightyfingers.com/) is a browser-based visual Phaser game editor. Create your maps with ease, position objects and share them in seconds. It also exports to native Phaser code. Excellent for quickly setting-up levels and scenes.
## Using Phaser
Phaser is provided ready compiled in the `build` folder of the repository. There are both plain and minified versions. The plain version is for use during development and the minified version for production.
### Custom Builds
Phaser includes a grunt based build system which allows you to strip out lots of additional features you may not require, saving hundreds of KB in the process. Don't use any Sound in your game? Then you can now exclude the entire sound system. Don't need Keyboard support? That can be stripped out too.
As a result of this work the minimum build size of Phaser is now just 80KB minified and gzipped.
See the [Creating a Custom Phaser Build](http://phaser.io/tutorials/creating-custom-phaser-builds) tutorial for details.
### Browserify / CJS
Phaser was never written to be modular. Everything exists under one single global namespace, and you cannot `require` selected parts of it into your builds. It expects 3 global vars to exist in order to work properly: `Phaser`, `PIXI` and `p2`. The following is one way of doing this:
```
window.PIXI = require('phaser/build/custom/pixi')
window.p2 = require('phaser/build/custom/p2')
window.Phaser = require('phaser/build/custom/phaser-split')
```
If you build a custom version of Phaser (see above) it will split the 3 core libs out into their own files, allowing you to require them as above.
We appreciate this is just a band-aid and not a proper use of modules, but please understand it was never built to be used this way. You're trying to fit a square peg in a round browserify-shaped hole, so compromises have to be made. Please don't open GitHub issues about it. We've no intention of changing Phaser at this stage of its life. Full module based development is being undertaken in Lazer.
### Webpack
Starting from Phaser 2.4.5 we now include a custom build for Webpack.
You need to add `p2` as a dependency.
##### Webpack Config
```
var path = require('path');
var webpack = require('webpack');
var phaserModule = path.join(__dirname, '/node_modules/phaser/');
var phaser = path.join(phaserModule, 'build/custom/phaser-split.js'),
pixi = path.join(phaserModule, 'build/custom/pixi.js'),
p2 = path.join(phaserModule, 'build/custom/p2.js');
module.exports = {
...
module: {
loaders: [
{ test: /pixi.js/, loader: "script" },
]
},
resolve: {
alias: {
'phaser': phaser,
'pixi.js': pixi,
'p2': p2,
}
}
...
}
```
##### Main js file
```
require('pixi.js');
require('p2');
require('phaser');
```
### Building from source
Should you wish to build Phaser from source you can take advantage of the provided [Grunt](http://gruntjs.com/) scripts. Ensure you have the required packages by running `npm install` first.
Run `grunt` to perform a default build to the `dist` folder.
## Games made with Phaser
Thousands of games have been made in Phaser. From game jam entries to titles by some of the largest entertainment brands in the world. Here is a tiny sample:

We add [new games](http://phaser.io/news/category/game) to the Phaser site weekly, so be sure to send us yours when it's finished!
## Requirements
Phaser requires a web browser that supports the [canvas tag](http://caniuse.com/#feat=canvas). This includes Internet Explorer 9+, Firefox, Chrome, Safari and Opera on desktop. iOS Safari, Android Browser and Chrome for Android are supported on mobile.
While Phaser does its best to ensure a consistent cross-platform experience, always be aware of browser and device limitations. This is especially important with regard to memory and GPU limitations on mobile, and legacy browser HTML5 compatibility.
### IE9
If you need to support IE9 / Android 2.x **and** use P2 physics then you must use the polyfill in the `resources/IE9 Polyfill` folder. If you don't use P2 (or don't care about IE9!) you can skip this.
### JavaScript and TypeScript
Phaser is developed in JavaScript. We've made no assumptions about how you like to code and were careful not to impose a strict structure upon you. You won't find Phaser split into modules, requiring a build step, or making you use a class / inheritance OOP approach. That doesn't mean you can't do so, it just means we don't *force* you to. It's your choice.
If you code with [TypeScript](http://www.typescriptlang.org/) there are comprehensive definition files in the `typescript` folder. They are for TypeScript 1.4+.
## Road Map
The majority of Phaser development is now taking place on the [Lazer](https://github.com/photonstorm/lazer) (Phaser 3) project. The Phaser 2 branch will still be supported and issues fixed, but roadmap features have been migrated over.
## Lazer
[Lazer](https://github.com/photonstorm/lazer) is the next generation of the Phaser game framework, and was previously called Phaser 3. Using a completely ES6 base it is renderer agnostic, allowing for DOM, SVG, Canvas and WebGL rendering, across desktop and mobile web browsers.
**Lazer is in active development but is not yet ready for production use.**
You can read all about the philosophy behind Lazer [here](http://phaser.io/news/2016/01/phaser-in-2015-and-beyond) or join the Google Group [mailing list](https://groups.google.com/d/forum/phaser3-dev) where progress reports are posted. You can also follow progress in the Phaser World newsletter.
## Change Log
## Version 2.4.9 - "Four Kings" - In Development
### New Features
* 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.getFarthestFrom 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)
### Updates
* TypeScript definitions fixes and updates (thanks @wingyplus @monagames @marineorganism @obamor)
* Docs typo fixes (thanks )
* 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)
### 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)
### 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.
*
