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.

23rd February 2018

Updated: Thank you for the continued amazing response to the 3.0.0 release! We've carried on working hard and now prepared 3.1.2 for you, which is available today. Check out the Change Log for more details.

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

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="http://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 3.1.2 - 23rd February 2018

Updates

• Hundreds of JSDoc fixes across the whole API.
• Tween.updateTweenData will now check to see if the Tween target still exists before trying to update its properties.
• If you try to use a local data URI in the Loader it now console warns instead of logs (thanks @samme)

Bug Fixes

• The KeyCode FORWAD_SLASH had a typo and has been changed to FORWAD_SLASH. Fix #3271 (thanks @josedarioxyz)
• Fixed issue with vertex buffer creation on Static Tilemap Layer, causing tilemap layers to appear black. Fix #3266 (thanks @akleemans)
• Implemented Static Tilemap Layer scaling and Tile alpha support.
• Fixed issue with null texture on Particle Emitter batch generation. This would manifest if you had particles with blend modes on-top of other images not appearing.
• Added missing data parameter to ScenePlugin. Fixes #3810 (thanks @AleBles)
