We have a Getting Started Guide which covers all you need to begin developing games with Phaser. From setting up a web server, to picking an IDE and coding your first game. Please start here no matter what your game-dev experience, before diving in to the API.

The single biggest Phaser resource is the Phaser web site. It has hundreds of tutorials listed and fresh ones are added every week. Keep coming back to see what's new!

Using Phaser with TypeScript? Check out this great series of Game From Scratch tutorials.

Prefer videos to reading? Lynda.com have published a video based course: HTML5 Game Development with Phaser (requires subscription)

Source Code Examples

Ever since we started Phaser we've been growing and expanding our extensive set of source code examples. Currently there are over 700 of them!

Browse the Phaser Examples or clone the examples repo and eat your heart out!

Interphase

Interphase is a programming book for Phaser developers of all skill levels.

With 400 pages of content you'll find detailed articles, game development "Making Of" guides and tutorials. All were written using the latest version of Phaser, so you won't be learning any out-dated tricks here.

As well as the book you get all the source code, graphics and assets to go with it, and lots of extras too.

Phaser Editor - A complete Phaser Editor

Phaser Editor is a brand new Eclipse based editor that offers lots of built-in tools specifically for Phaser developers. 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 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.

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 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

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 or join the Google Group mailing list 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.getFurthestFrom 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)
Game Objects including Sprite, Image, Particle, TilemapLayer, Text, BitmapText and TileSprite have a new property called data. This is an empty Object that Phaser will never touch internally, but your own code, or Phaser Plugins, can store Game Object specific data within it. This allows you to associate data with a Game Object without having to pollute or change its class shape.
TilemapLayers will now collide properly when they have a position that isn't set to 0x0. For example if you're stitching together several maps, one after the other, and manually adjust their scrollX/Y properties (thanks @Upperfoot #2522)
There are a bunch of new Phaser consts available to help with setting the angle of a Game Object. They are Phaser.ANGLE_UP, ANGLE_DOWN, ANGLE_LEFT, ANGLE_RIGHT, ANGLE_NORTH_EAST, ANGLE_NORTH_WEST, ANGLE_SOUTH_EAST and ANGLE_SOUTH_WEST.
Math.between will return a value between the given min and max values.
InputHandler.dragDistanceThreshold gives you more fine control over when a Sprite Drag event will start. It allows you to specify a distance, in pixels, that the pointer must have moved before the drag will begin.
InputHandler.dragTimeThreshold gives you more fine control over when a Sprite Drag event will start. It allows you to specify a time, in ms that the pointer must have been held down for, before the drag will begin.
InputHandler.downPoint is a new Point object that contains the coordinates of the Pointer when it was first pressed down on the Sprite.
There are two new Phaser consts available, for help with orientation of games or Game Objects. They are Phaser.HORIZONTAL, Phaser.VERTICAL, Phaser.LANDSCAPE and Phaser.PORTRAIT.
InputHandler.dragStopBlocksInputUp is a boolean that allows you to control what happens with the input events. If false (the default) then both the onInputUp and onDragStop events will get dispatched when a Sprite stops being dragged. If true then only the onDragStop event is dispatched, and the onInputUp is skipped.
Group.inputEnableChildren is a new property. If set to true will automatically call inputEnabled = true on any children added to, or created by, the Group.
PIXI.DisplayObjectContainer.ignoreChildInput is a new property. If true then the children will not be considered as valid for Input events. Because this has been applied to DisplayObjectContainer it means it's available in Group, Sprite and any other display level object. Using this boolean you can disable input events for all children in an entire Group, without having to iterate anything or deep-set flags.
InputHandler._pointerOverHandler and _pointerOutHandler have new arguments silent - if true then they will not dispatch any Signals from the parent Sprite.
Pointer.interactiveCandidates is a new Array that is erased and re-populated every time this Pointer is updated. It contains references to all of the Game Objects that were considered as being valid for processing by this Pointer, during the most recent update. To be valid they must have suitable a priorityID, be Input enabled, be visible and actually have the Pointer over them. You can check the contents of this array in events such as onInputDown, but beware: it is reset every update.
Pointer.swapTarget allows you to change the Pointer.targetObject object to be the one provided. This allows you to have fine-grained control over which object the Pointer is targeting.
Input.setInteractiveCandidateHandler allows you to add a callback that is fired every time Pointer.processInteractiveObjects is called. The purpose of processInteractiveObjects is to work out which Game Object the Pointer is going to interact with. It works by polling all of the valid game objects, and then slowly discounting those that don't meet the criteria (i.e. they aren't under the Pointer, are disabled, invisible, etc). Eventually a short-list of 'candidates' is created. These are all of the Game Objects which are valid for input and overlap with the Pointer. If you need fine-grained control over which of the items is selected then you can use this callback to do so. The callback will be sent 3 parameters: 1) A reference to the Phaser.Pointer object that is processing the Items. 2) An array containing all potential interactive candidates. This is an array of InputHandler objects, not Sprites. 3) The current 'favorite' candidate, based on its priorityID and position in the display list. Your callback MUST return one of the candidates sent to it.
Group.onChildInputDown is a new Signal that you can listen to. It will be dispatched whenever any immediate child of the Group emits an onInputDown signal itself. This allows you to listen for a Signal from the Group, rather than every Sprite within it.
Group.onChildInputUp is a new Signal that you can listen to. It will be dispatched whenever any immediate child of the Group emits an onInputUp signal itself. This allows you to listen for a Signal from the Group, rather than every Sprite within it.
Group.onChildInputOver is a new Signal that you can listen to. It will be dispatched whenever any immediate child of the Group emits an onInputOver signal itself. This allows you to listen for a Signal from the Group, rather than every Sprite within it.
Group.onChildInputOut is a new Signal that you can listen to. It will be dispatched whenever any immediate child of the Group emits an onInputOut signal itself. This allows you to listen for a Signal from the Group, rather than every Sprite within it.

Updates

TypeScript definitions fixes and updates (thanks @wingyplus @monagames @marineorganism @obamor @BaroqueEngine)
Docs typo fixes (thanks @seanirby @johnrees)
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)
Removed the Stage.updateTransform calls from the main game loop, because it happens automatically as part of Game.updateLogic anyway, so was duplicating the workload for no reason.
TilemapLayer.postUpdate could potentially be called several times per frame (depending on device frame rate), which would cause multiple texture redraws, even though only the last texture is used during rendering. This has now been modified so that the local TilemapLayer canvas is only re-rendered once per frame, during the rendering phase, and not during the logic update phase.
Group.preUpdate now iterate through the display list forwards, instead of in reverse, to match it with how Stage.preUpdate works.
Stage.postUpdate is now a lot smaller, with no conditional branching if there is a Camera Target or not.
Within RequestAnimationFrame both updateRAF and updateSetTimeout now only call game.update if isRunning is true. This should avoid asynchronous Game destroy errors under environments like Angular (thanks @flogvit #2521)
Group.removeAll has a new argument destroyTexture which allows you to optionally destroy the BaseTexture of each child, as it is removed from the Group (thanks @stoneman1 #2487)
PluginManager.remove has a new argument destroy (defaults to true) which will let you optionally called the destroy method of the Plugin being removed.
Cache.getJSON used to incorrectly bring back a deep-copy of the Phaser.Utils object, instead of just a clone of the JSON object requested (thanks @drhayes #2524 #2526)
The DisplayObject.renderOrderID used to run in reverse. I.e. in a display list with 10 sprites on it, the first sprite (at the bottom of the list, rendering behind all the others) would have a renderOrderID of 9, where-as the top-most sprite, rendering above all others, would have a renderOrderID of 0. While this didn't cause any side-effects internally, it's arguably illogical. So the process has been reversed, and renderOrderIDs are now accumulative, starting at zero each frame, and increasing as it iterates down the display list. So the higher the ID, the more "on-top" of the output the object is.
InputHandler.validForInput and Pointer.processInteractiveObjects have been updated to reflect the new renderOrderID sequence (see above).
Group.add has a new optional argument index which controls the index within the group to insert the child to. Where 0 is the bottom of the Group.
Group.addAt has been refactored to be a simple call to Group.add, removing lots of duplicate code in the process.
Group.create has a new optional argument index which controls the index within the group to insert the child to. Where 0 is the bottom of the Group. It also now makes proper use of Group.add, cutting down on more duplicate code.
Group.createMultiple now returns an Array containing references to all of the children that the method created.
Keyboard now uses a new internal method getKeyCode to normalize the key code value based on browser support. It first checks for event.key, then event.keyIdentifier and finally event.keyCode (thanks @SVasilev #2542)

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)
Sound.isPlaying was set to false when doing an audio loop, but never set back to true if it's a sound not using a marker (thanks @TheJasonReynolds #2529)
Phaser.Rectangle.aabb would fail if the Rectangles used negative offsets. It now calculates the bounds accurately (thanks @fillmoreb #2545)
