What's New

7th June 2022

We've been quietly but solidly working away on Phaser 3.60 for months now and are very close to release. Today I'm happy to say that 3.60 Beta 9 has been published and I would urge you to test it, if you can do so. It should be a safe drop-in replacement for Phaser 3.55, with very little need for changes to your code. However, it does bring a lot of new features and fixes to the table.

Some of the new features include:

Sprite FX - The ability to create and use SpriteFX Pipelines directly on Sprite Game Objects. These allow a really easy way to define per-Sprite shaders, including extra padding space, perfect for effects such as blur, distort, glow, outline, shadow and more.

Compressed Texture Support - Phaser 3.60 contains support for Compressed Textures. It can parse both KTX and PVR containers and within those has support for the following formats: ETC, ETC1, ATC, ASTC, BPTC, RGTC, PVRTC, S3TC and S3TCSRB. Compressed Textures differ from normal textures in that their structure is optimized for fast GPU data reads and lower memory consumption. Popular tools that can create compressed textures include PVRTexTool, ASTC Encoder and Texture Packer.

Matter Physics v0.18 - We have updated the version of Matter Physics to the latest v0.18 release. This is a big jump and brings with it quite a few internal changes to Matter, as well as a ~40% performance improvement.

There are also hundreds of updates and bug fixes across the entire codebase.

As always, I have been careful to record all of these in their own Change Log. So it's easier for you to identify which change happened in the 3.60 version specifically.

Beta 9 is available now from the Releases page. You can also download it from npm:

npm i phaser@3.60.0-beta.9

I have published new TypeScript defs files that align with this version. You can find them in the types folder of this repository.

If you find any problems with this release I'd urge you to please report them in GitHub issues.

As usual, I'd like to send my thanks to the Phaser community for their help in both reporting issues and submitting pull requests to fix them. So, please do spend some time digging through the Change Log. I assure you, it's worth while :)

I'd like to send a massive thank-you to everyone who supports Phaser on Patreon, GitHub Sponsors and our corporate backers. Your continued funding allows me to keep working on Phaser full-time and this monster of a new release is the very real result of that. If you've ever considered becoming a backer, now is the perfect time!

If you'd like to stay abreast of developments then I'm now publishing them to the Phaser Patreon. Here you can find the latest development reports including the concepts behind Phaser 4.

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

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

Support Phaser

Because Phaser is an open source project, we cannot charge for it in the same way as traditional retail software. What's more, we don't ever want to. After all, it's built on, and was born from, open web standards. It's part of our manifesto that the core framework will always be free, even if you use it commercially, as many of you do.

You may not realize it, but because of this, we rely 100% on community backing to fund development.

Those funds allow Phaser to improve, and when it improves, everyone involved benefits. Your support helps secure a constant cycle of updates, fixes, new features and planning for the future.

We use Patreon to manage the backing and you can support Phaser from $1 per month. The amount you pledge is entirely up to you and can be changed as often as you like. Patreon renews monthly, just like Netflix. You can, of course, cancel at any point. Tears will be shed on this end, but that's not your concern.

You can also support us by using crypto currencies. The Phaser wallet addresses are:

  • Ethereum: 0x6a716A122Ad186ECE865C55D16c1D361f1B13724
  • BSC / AVAX / Polygon: 0x94aC3F640b8749AbD1d44f29A62ffeB32CA34628

Extra special thanks to the following companies whose support makes Phaser possible:

Download Phaser

Phaser 3 is available via GitHub, npm and CDNs:

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@3.55.2/dist/phaser.js"></script>

or the minified version:

<script src="//cdn.jsdelivr.net/npm/phaser@3.55.2/dist/phaser.min.js"></script>

API Documentation

Go to https://newdocs.phaser.io/ to read the docs online using our brand new interface. Use the links to navigate the namespaces, classes and Game Objects lists and also use the new search box.

The documentation for Phaser 3 is an on-going project. Please help us by contributing improved docs and examples.

TypeScript Definitions

The TypeScript definitions can be found inside the types folder. They are also referenced in the types entry in package.json.

Depending on your project, you may need to add the following to your tsconfig.json file:

"typeRoots": [
    "./node_modules/phaser/types"
],
"types": [
    "Phaser"
]

We recently published a new Phaser 3 TypeScript Project Template, which you can use to get started with if you like.

The TS defs are automatically generated from the JSDoc comments found in the Phaser source code. If you wish to help refine them then you must edit the Phaser JSDoc blocks directly, not the defs file. You can find more details about the parser we built in the scripts/tsgen folder.

Webpack

We use Webpack to build Phaser and we take advantage of its conditional build flag feature to handle 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. Recent changes to our build steps mean you should now be able to use any other packager, like Parcel, without any config changes.

License

Phaser is released under the MIT License.

Getting Started

Tutorials and guides on Phaser 3 development are being published every week.

We've 3 tutorials related specifically to creating Facebook Instant Games with Phaser:

Source Code Examples

During our development of Phaser 3, we created hundreds of examples with the full source code and assets ready available. These examples are now fully integrated into the Phaser website. You can also browse them on Phaser 3 Labs via a more advanced interface, or clone the examples repo. We are constantly adding to and refining these examples.

Hathora

Hathora is a framework for creating online multiplayer games with a focus on providing the best developer experience possible. The framework handles aspects such as State Synchronization, persistence, and authentication so that you can focus on building your game. Once you’ve built your game, you can deploy it to Hathora Cloud with a single command, and it will push your game to servers all over the world, automatically scaling up or down based on the user load. Visit the Hathora documentation to learn more.

Huge list of Phaser 3 Plugins

Super community member RexRainbow has been publishing Phaser 3 content for years, building up an impressive catalogue in that time. You'll find loads of plugins, from UI controls such as text input boxes, to Firebase support, Finite State Machines and lots more. As well as the plugins there is also a comprehensive set of 'Notes' about Phaser 3, going into great detail about how the various systems work. It's an invaluable resource and well worth checking out at https://rexrainbow.github.io

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://cdn.jsdelivr.net/npm/phaser@3.55.2/dist/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('https://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:

Phaser 3 Demo

(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!

Ourcade

Ourcade have published two great Phaser 3 books. They'll take you from getting set-up, through to finishing your first game using modern JavaScript or TypeScript and they're both completely free! They also publish a huge range of quality tutorials and videos, so be sure to check out their site every week.

HTML5 Cross Platform Game Development with Phaser 3

Learn the secrets of HTML5 game development with Phaser 3.50 while building a cross platform endless runner game. Designed both for beginners and skilled programmers, the course guides you from an empty folder introducing the bare bones of JavaScript to advanced Phaser 3 features. Find out more details about HTML5 Cross Platform Game Development with Phaser.

Building Phaser

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 and should also create your own builds.

Custom Builds

Phaser 3 is built using Webpack and we take advantage of the Webpack definePlugin feature to allow for conditional building of the Canvas and WebGL renderers and extra plugins. You can custom the build process to only include the features you require. Doing so can cut the main build file size down to just 70KB.

Read our comprehensive guide on creating Custom Builds of Phaser 3 for full details.

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 on your source directory.

You can then run webpack to create a development build in the build folder which includes source maps for local testing. You can also npm run dist to create a minified packaged build in the dist folder. For a list of all commands available use npm run help.
