Phaser

Phaser is a fast, free and fun open source HTML5 game framework. It uses a custom build of 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. As a result of rapid support and a developer friendly API Phaser is currently one of the most starred 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!

What's new in Phaser 2.4.7

TBA

Phaser 2.4.7 is our second 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.

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.

As always, keep you eyes on the Phaser web site or Twitter for the latest news.

Finally we'd be extremely grateful if you could get involved with our Phaser Patreon campaign. The uptake so far has been fantastic. Thank you to everyone who now supports Phaser development and shares our belief in the future of HTML5 gaming and Phasers role in that.

Happy coding everyone! See you on the forums.

Cheers,

Rich - @photonstorm

Game Mechanic Explorer

The Game Mechanic Explorer 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 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 tutorial for details.

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 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:

Artwork copyright their respective owners.

We add new games 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. 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 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 (Phaser 3) project. The Phaser 2 branch will still be supported and issues fixed, but roadmap features have been migrated over.

Lazer (Phaser 3)

Lazer is the new name for Phaser 3.

Lazer is the next generation of the Phaser game framework. Using a completely ES6 base it is renderer agnostic, allowing for DOM, SVG, Canvas and WebGL rendering, across desktop and mobile web browsers.

You can read all about the philosophy behind Lazer here or join the Google Groups mailing list where progress reports are posted on a regular basis.

Change Log

Version 2.4.7 - "Hinderstap" - In Development

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)

Updates

• TypeScript definitions fixes and updates (thanks @clark-stevenson)
• Docs typo fixes (thanks @thiagojobson)
• 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)
• 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 un-compressed 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)
• 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)
• 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)

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)

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)

For changes in previous releases please see the extensive Version History.
