    Phaser CE (Community Edition) - HTML5 Game Framework

    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, and supports desktop and mobile web browsers. Games can be compiled to iOS, Android and native desktop apps via 3rd party tools. You can use JavaScript or TypeScript for development. Years after release, Phaser is still one of the most starred game frameworks on GitHub.

    Thousands of developers worldwide use Phaser. From indies and multi-national digital agencies, to schools and Universities. Each creating their own incredible games.

    Phaser v2 was originally built and maintained by the company Photon Storm, but was turned over to the community in November 2016.

    What's New

    22nd November 2016

    Today we hand over Phaser 2.7 to you, the awesome open source community, to maintain.

    Phaser 2 was a massive milestone for us, and we're still constantly amazed at all the cool things you've created, and continue to create with it. Thank you to everyone who has submitted an issue or pull request over the years, or helped the framework grow in any shape or capacity.

    As of today all of our in-house resources are spent on building Phaser 3 and beyond. However we fully recognize that lots of you still use Phaser 2, and have a lot to contribute to its future. So this is what we've done:

    • Phaser 2.6.2 is the last 'official' release, published on npm as phaser
    • Phaser 2.7.0 and all future versions have been given to the community to maintain, published on npm as phaser-ce

    All Pull Requests made against the v2-community version will be unconditionally approved. We'll give GitHub permissions to a select few individuals to help with this process. When you, the community, request it, we will publish new versions to npm.

    If you are migrating pull requests from the old folder structure, you might find the following process useful to migrate your PRs over to the new structure:

    First, from your forked repo, make sure master is up to date by fetching upstream. To do this easily:

    git checkout master
    git reset --hard upstream/master
    
    1. cd into your forked repo locally
    2. git checkout x where x is your feature branch
    3. git rebase master
    4. git push --force x and then resubmit a PR on the GitHub UI

    We believe this set-up will give us the best of both worlds. It will allow us to continue focusing our efforts on Phaser 3. And it will allow the community to enhance Phaser 2 for as long as they wish.

    As always, check the Change Log to see what was added recently.

    Keep your eyes on the web site, and subscribe to the weekly Phaser World newsletter. You can also follow on Twitter, or chat in the Phaser Slack and Discord channels.

    There are also now more ways than before to help support the development of Phaser. The uptake so far has been fantastic, but this is an on-going mission. Thank you to everyone who supports our development. Who shares our belief in the future of HTML5 gaming, and Phasers role in that.

    Happy coding everyone!

    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.

    Building 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. You can also create your own builds.

    Custom Builds

    Phaser includes a grunt based build system, which allows you to strip out features you may not require, saving hundreds of KB in the process. Don't use any Sound in your game? Then exclude the entire sound system. Don't need Keyboard support? That can be excluded 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.

    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 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 as we've no intention of changing Phaser at this stage of its life. Full module based development is available in Phaser v3.

    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.

    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. You can find hundreds more on our web site.

    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 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 ES5 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+.

    • Some browsers uses CancelRequestAnimationFrame instead of CancelAnimationFrame and it is now fixed (thanks @stoneman1)

    Version 2.7.0 - "World's End" - 22nd November 2016

    New Features

    • Multiple Batched Texture support is now available. This is a WebGL feature that can seriously decrease the volume of draw calls made in complex, or asset heavy, games. To enable it you can either use the new renderer type Phaser.WEBGL_MULTI, or you can pass the property multiTexture: true in a Phaser.Game configuration object. Once enabled, it cannot be disabled.
    • game.renderer.setTexturePriority is the method that goes with the Multiple Texture support. It takes an array as its single argument. The array consists of Phaser.Cache image key strings. Phaser will then try to batch as many of the textures as it can, depending on the hardware limits. If for example the GPU can only batch 8 textures, and you provide an array of 16, then only the first 8 in the array will be batched.
    • Phaser now supports Compressed Textures under WebGL. It will handle loading PVRTC, DDS, ETC1, KTX and PKM texture formats, and supports PVRTC, S3TC and ETC1 compression formats, with a TrueColor fallback for standard PNGs. Using compressed textures allows the GPU to decode, and access, the texture data much faster than traditional image compression schemes such as JPEG. iOS devices in particular benefit greatly from using PowerVR Texture Compression (PVRTC). The resulting textures take up less memory than their traditional counterparts, and when it comes to iOS, every bit of memory helps! Look at the new Loader.texture method for details on using this. You can also pass a file object to Loader.image, again, please see the docs for details.
    • Support for Rotated Frames in Texture Atlases is now included for WebGL and Canvas. If you use software such as Texture Packer, you may now enable the 'Allow Rotation' checkbox, which can often help getting smaller, or more compact, atlases. As a result, the Texture.rotated and Frame.rotated properties are now in use.
    • Frame.rotationDirection has been removed. It isn't needed, as modern texture packers only rotate 90 degrees clockwise anyway, and Phaser only supports this rotation direction.
    • Weapon.multiFire is a new property that allows you to set a Weapon as being allowed to call fire as many times as you like, per game loop. This allows a single Weapon instance to fire multiple bullets.
    • Weapon.fire has two new arguments: offsetX and offsetY. If the bullet is fired from a tracked Sprite or Pointer, or the from argument is set, this applies a horizontal and vertical offset from the launch position.
    • Weapon.fireOffset attempts to fire a single Bullet from a tracked Sprite or Pointer, but applies an offset to the position first. This is a shorter form of calling Weapon.fire and passing in the offset arguments.
    • Weapon.fireMany attempts to fire multiple bullets from the positions defined in the given array. If you provide a from argument, or if there is a tracked Sprite or Pointer, then the positions are treated as offsets from the given objects position. If from is undefined, and there is no tracked object, then the bullets are fired from the given positions, as they exist in the world.
    • When loading a Sprite Sheet you can now specify the number of frames to skip, as the frames are extracted from the sheet and converted to Frames (thanks @arefiev #2763)
    • Math.random returns a random float in the range given (thanks @JTronLabs #2760)
    • Text.splitRegExp is a new property that allows you to control the regular expression that is used to split the text into multiple lines (thanks @dai-shi #1403)
    • Cache.addBitmapFontFromAtlas allows you to add a Bitmap Font to the Cache, that is comprised of a frame from a Texture Atlas, and the font data (in JSON or XML format). Once added you can use the Bitmap Font in the same way as you would any Bitmap Font (#2614)

    Updates

    • TypeScript definitions fixes and updates (thanks @chriteixeira @StealthC @Lopdo @nickdbush)
    • Docs typo fixes (thanks @JTronLabs @samme @jorgesumle)
    • Phaser.Line.fromSprite now uses the Sprite.centerX and centerY properties if the useCenter argument is true. Before it required you to have overridden the Sprite and added the property yourself (thanks @samme #2729)
    • Updated the pointer check code in the Device class, to get rid of the message Navigator.pointerEnabled is a non-standard API added for experiments only. It will be removed in near future. in Chrome.
    • The P2 Physics library has been updated to 0.7.1. This is still quite out of date, but as soon as they release their latest build (hopefully soon) we'll update to that.
    • Math.between has been strengthened and the docs improved (thanks @JTronLabs #2760)
    • Camera.fade has a new argument alpha to control the alpha level of the effect (thanks @rgk #2493)
    • Camera.flash has a new argument alpha to control the alpha level of the effect (thanks @rgk #2493)
    • Phaser.SpriteBatch was incorrectly applying the prototypes, causing the Sprite Batch render methods to be replaced by the normal DisplayObjectContainer ones, meaning nothing was really batched at all. This has now been fixed, and PIXI.SpriteBatch removed, as it's no longer required.
    • PIXI.RenderTexture has been removed, and all functionality merged in to Phaser.RenderTexture, to cut down on the number of internal classes and inheritance going on.
    • PIXI.TilingSprite has been removed, and all functionality merged in to Phaser.TileSprite, to cut down on the number of internal classes and inheritance going on.
    • PIXI.CanvasPool has been moved into the Phaser utils folder, and renamed to Phaser.CanvasPool. All references to PIXI.CanvasPool have been updated to match the new namespace.
    • PIXI.EarCut has been moved into the Phaser utils folder, and renamed to Phaser.EarCut. All references to PIXI.EarCut have been updated to match the new namespace.
    • Device.canHandleAlpha is a new boolean property that stores is the browser is capable of tinting with alpha.
    • Device.canUseMultiply is a new boolean property that stores whether or not the Canvas BlendModes are supported, consequently the ability to tint using the multiply method.
    • Math.getNextPowerOfTwo will get the next power of two for the given value.
    • Math.isPowerOfTwo will return a boolean if the given width and height are a power of two.
    • Color.hexToRGBArray converts a hex color value to an [R, G, B] array.
    • Color.RGBArrayToHex converts an RGB color array, in the format: [R, G, B], to a hex color value.
    • PIXI.AbstractFilter has been merged into the Phaser.Filter class. All references to PIXI.AbstractFilter have been updated to use Phaser.Filter instead.
    • PIXI.Rope and PIXI.Strip have been removed, and all functionality merged in to Phaser.Rope, to cut down on the number of internal classes and inheritance going on.
    • PIXI.Graphics and PIXI.GraphicsData have been removed, and all functionality merged in to Phaser.Graphics, to cut down on the number of internal classes and inheritance going on.
    • WebGLGraphics and CanvasGraphics have been updated so that it checks for Phaser Geometry shape types internally.
    • PIXI.PI_2 has been removed, because it's available via Phaser.Math.PI2. The only place PI_2 was used has been updated to now use PI2.
    • The polyfills.js file now polyfills in for Float32Array, Uint16Array and ArrayBuffer.
    • PIXI.Float32Array, PIXI.Uint16Array, PIXI.Uint32Array and PIXI.ArrayBuffer have all been removed, and replaced with their own proper native versions. The polyfill now captures any instances where the browser needs to fall back to an Array instead.

    Bug Fixes

    • DisplayObjectContainer.removeChildren was incorrectly using the begin var, instead of beginIndex (thanks @alex-espinoza #2742 #2741)
    • Camera.fx is tested to see if it exists, before resetting it (thanks @samme #2739 #2738)
    • The Weapon Plugin will no longer crash if the Weapon's bullets have not yet been initialized before setting a new bullet class (thanks @JTronLabs #2731)
    • Groups with fixedToCamera set on them now factor in the camera scale (thanks @kevinAlbs #2771)
    • Text.width and Text.height now divide the result by the Text.resolution, to avoid incorrect dimensions on High DPI devices (thanks @mattahj #2146)
    • If you called Video.changeSource, and then immediately called Video.play after it, it would fire the onComplete event twice (thanks @jaraiza #2543)
    • The Video.playing property didn't check to see if the Video existed, and would throw the error Uncaught TypeError: Cannot read property 'paused' of null if you called it after destroying the video (thanks @Tetley #2740)
    • Fixed bug in DisplayObject where it was using PI_2 instead of PI2.

    Pixi Updates
