Phaser - HTML5 Game Framework

Phaser is a fast, free, and fun open source HTML5 game framework that offers WebGL and Canvas rendering across desktop and mobile web browsers. Games can be compiled to iOS, Android and native apps by using 3rd party tools. You can use JavaScript or TypeScript for development.

Phaser is available in two versions: Phaser 3 and Phaser CE - The Community Edition. Phaser CE is a community-lead continuation of the Phaser 2 codebase and is hosted on a separate repo. Phaser 3 is the next generation of Phaser.

Along with the fantastic open source community, Phaser is actively developed and maintained by Photon Storm. 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 from indie and multi-national digital agencies, and universities worldwide use Phaser. You can take a look at their incredible games.

19th April 2018

Updated: We've just released Phaser 3.6.0. This release introduces the full version of Containers, updates more documentation and carries on the update and bug fixing work. It comes shortly after the 3.5 and 3.4 releases which unified the Camera Effects and introduced powerful new Scene Transitions. We appreciate that our current release velocity is extremely high, often with several versions per week, so as always, please check out the Change Log for comprehensive details about what recent versions contain.

After 1.5 years in the making, tens of thousands of lines of code, hundreds of examples and countless hours of relentless work: Phaser 3 is finally out. It has been a real labor of love and then some!

Please understand this is a bleeding-edge and brand new release. There are features we've had to leave out, areas of the documentation that need completing and so many cool new things we wanted to add. But we had to draw a line in the sand somewhere and 3.0.0 represents that.

For us this is just the start of a new chapter in Phaser's life. We will be jumping on bug reports as quickly as we can and releasing new versions rapidly. We've structured v3 in such a way that we can push out point releases as fast as needed.

We publish our Developer Logs in the weekly Phaser World newsletter. Subscribe to stay in touch and get all the latest news from us and the wider Phaser community.

You can also follow Phaser on Twitter and chat with fellow Phaser devs in our Slack and Discord channels.

Phaser 3 wouldn't have been possible without the fantastic support of the community and Patreon. Thank you to everyone who supports our work, who shares our belief in the future of HTML5 gaming, and Phaser's role in that.

Happy coding everyone!

Cheers,

Rich - @photonstorm

Extra special thanks to our top-tier sponsors: Orange Games and CrossInstall.

Every week we publish the Phaser World newsletter. It's packed full of the latest Phaser games, tutorials, videos, meet-ups, talks, and more. The newsletter also contains our weekly Development Progress updates which let you know about the new features we're working on.

Over 100 previous editions can be found on our Back Issues page.

Phaser 3 is available via GitHub, npm and CDNs:

• Clone the git repository via https, ssh or with the Github Windows or Mac clients.
• Download as zip
• Download the build files: phaser.js and phaser.min.js

NPM

Install via npm:

npm install phaser

CDN

Phaser is on jsDelivr which is a "super-fast CDN for developers". Include the following in your html:

<script src="//cdn.jsdelivr.net/npm/phaser@3.6.0/dist/phaser.js"></script>

or the minified version:

<script src="//cdn.jsdelivr.net/npm/phaser@3.6.0/dist/phaser.min.js"></script>

API Documentation

1. Go to https://photonstorm.github.io/phaser3-docs/index.html to read the docs online.
2. Checkout the phaser3-docs repository and then read the documentation by pointing your browser to the local docs/ folder.

The documentation for Phaser 3 is an on-going project. Please help us by searching the Phaser code for any instance of the string [description] and then replacing it with some documentation.

TypeScript Definitions

TypeScript Definitions are now available.

They are automatically generated from the jsdoc comments in the Phaser source code. If you wish to help refine them then you must edit the Phaser jsdoc blocks directly. You can find more details, including the source to the conversion tool we wrote in the Docs repo.

Webpack

We use Webpack to build Phaser and we take advantage of several features specific to Webpack to do this, including raw-loader to handle our shader files and build-time flags for renderer swapping.

If you wish to use Webpack with Phaser then please use our Phaser 3 Project Template as it's already set-up to handle the build conditions Phaser needs.

License

Phaser is released under the MIT License.

Phaser 3 is so brand new the "paint is still wet", but tutorials and guides are starting to come out!

• Getting Started with Phaser 3 (useful if you are completely new to Phaser)
• Making your first Phaser 3 Game
• Phaser 3 Bootstrap and Platformer Example

Also, please subscribe to the Phaser World newsletter for details about new tutorials as they are published.

Source Code Examples

During our development of Phaser 3, we created hundreds of examples with the full source code and assets. Until these examples are fully integrated into the Phaser website, you can browse them on Phaser 3 Labs, or clone the examples repo. Note: Not all examples work, sorry! We're tidying them up as fast as we can.

Create Your First Phaser 3 Example

Create an index.html page locally and paste the following code into it:

<!DOCTYPE html>
<html>
<head>
    <script src="https://labs.phaser.io/build/phaser-arcade-physics.min.js"></script> 
</head>
<body>

    <script></script>

</body>
</html>

This is a standard empty webpage. You'll notice there's a script tag that is pulling in a build of Phaser 3, but otherwise this webpage doesn't do anything yet. Now let's set-up the game config. Paste the following between the <script></script> tags:

var config = {
    type: Phaser.AUTO,
    width: 800,
    height: 600,
    physics: {
        default: 'arcade',
        arcade: {
            gravity: { y: 200 }
        }
    },
    scene: {
        preload: preload,
        create: create
    }
};

config is a pretty standard Phaser 3 Game Configuration object. We tell config to use the WebGL renderer if it can, set the canvas to a size of 800x600 pixels, enable Arcade Physics, and finally call the preload and create functions. preload and create have not been implemented yet, so if you run this JavaScript code, you will have an error. Add the following after config:

var game = new Phaser.Game(config);

function preload ()
{
    this.load.setBaseURL('http://labs.phaser.io');

    this.load.image('sky', 'assets/skies/space3.png');
    this.load.image('logo', 'assets/sprites/phaser3-logo.png');
    this.load.image('red', 'assets/particles/red.png');
}

function create ()
{
}

game is a Phaser Game instance that uses our configuration object config. We also add function definitions for preload and create. The preload function helps you easily load assets into your game. In preload, we set the Base URL to be the Phaser server and load 3 PNG files.

The create function is empty, so it's time to fill it in:

function create ()
{
    this.add.image(400, 300, 'sky');

    var particles = this.add.particles('red');

    var emitter = particles.createEmitter({
        speed: 100,
        scale: { start: 1, end: 0 },
        blendMode: 'ADD'
    });

    var logo = this.physics.add.image(400, 100, 'logo');

    logo.setVelocity(100, 200);
    logo.setBounce(1, 1);
    logo.setCollideWorldBounds(true);

    emitter.startFollow(logo);
}

Here we add a sky image into the game and create a Particle Emitter. The scale value means that the particles will initially be large and will shrink to nothing as their lifespan progresses.

After creating the emitter, we add a logo image called logo. Since logo is a Physics Image, logo is given a physics body by default. We set some properties for logo: velocity, bounce (or restitution), and collision with the world bounds. These properties will make our logo bounce around the screen. Finally, we tell the particle emitter to follow the logo - so as the logo moves, the particles will flow from it.

Run it in your browser and you'll see the following:

(Got an error? Here's the full code)

This is a tiny example, and there are hundreds more for you to explore, but hopefully it shows how expressive and quick Phaser is to use. With just a few easily readable lines of code, we've got something pretty impressive up on screen!

Subscribe to our weekly newsletter for further tutorials and examples.

There are both plain and minified compiled versions of Phaser in the dist folder of the repository. The plain version is for use during development, and the minified version is for production use. You can also create your own builds.

Custom Builds

Phaser 3 must be built using Webpack. We take advantage of a number of Webpack features and plugins which allow us to properly tailor the build process. You can elect exactly which features are bundled into your version of Phaser. We will release a tutorial covering the process shortly, but for now please look at our webpack config files to get an idea of the required settings.

Building from Source

If you wish to build Phaser 3 from source, ensure you have the required packages by cloning the repository and then running npm install.

You can then run webpack to create a development build in the build folder which includes source maps for local testing. You can also run npm run dist to create a minified packaged build in the dist folder.

Version 3.6.0 - Asuna - 19th April 2018

New Features

• Containers are now fully available! We have removed the beta warning and fixed the way in which they work with Cameras, input and scroll factors. They are also fully documented, so please see their docs and examples for use.
• Group.getLast will return the last member in the Group matching the search criteria.
• Group.getFirstNth will return the nth member in the Group, scanning from top to bottom, that matches the search criteria.
• Group.getLastNth will return the nth member in the Group, scanning in reverse, that matches the search criteria.
• Group.remove has a new optional argument destroyChild that will call destroy on the child after removing it.
• Group.clear has a new optional argument destroyChild that will call destroy on all children in the Group after removing them.

Updates

• Impact Physics Game Objects have changed setLite to setLiteCollision.
• Impact Physics Game Objects have changed setPassive to setPassiveCollision.
• Impact Physics Game Objects have changed setFixed to setFixedCollision.
• Impact Physics Game Objects have changed setActive to setActiveCollision, previously the setActive collision method was overwriting the Game Objects setActive method, hence the renaming.
• The modifications made to the RTree class in Phaser 3.4.0 to avoid CSP policy violations caused a significant performance hit once a substantial number of bodies were involved. We have recoded how the class deals with its accessor formats and returned to 3.3 level performance while still maintaining CSP policy adherence. Fix #3594 (thanks @16patsle)
• The Retro Font namespace has changed to Phaser.GameObjects.RetroFont. Previously, you would access the parser and constants via BitmapText, i.e.: Phaser.GameObjects.BitmapText.ParseRetroFont.TEXT_SET6. This has now changed to its own namespace, so the same line would be: Phaser.GameObjects.RetroFont.TEXT_SET6. The Parser is available via Phaser.GameObjects.RetroFont.Parse. This keeps things cleaner and also unbinds RetroFont from BitmapText, allowing you to cleanly exclude it from your build should you wish. All examples have been updated to reflect this.
• If using the removeFromScene option in Group.remove or Group.clear it will remove the child/ren from the Scene to which they belong, not the Scene the Group belongs to.

Bug Fixes

• Fixed a bug that caused data to not be passed to another Scene if you used a transition to start it. Fix #3586 (thanks @willywu)
• Group.getHandler would return any member of the Group, regardless of the state, causing pools to remain fixed at once member. Fix #3592 (thanks @samme)
