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.
|
|
|
|
Along with the fantastic open source community, Phaser is actively developed and maintained by [Photon Storm](http://www.photonstorm.com). As a result of rapid support, and a developer friendly API, Phaser is currently one of the [most starred](https://github.com/collections/javascript-game-engines) game frameworks on GitHub.

After 13 beta releases, over 200 resolved issues, thousands of lines of new code and the culmination of over 6 months incredibly hard work, Phaser 3.50 was finally released in December 2020 and we're continuing with updates into 2021 with this new 3.55 release. 3.55 focuses mostly on fixing issues, but also addresses a performance issue with mixing Sprites and Graphics objects together.
|
|
|
|
It's not hyperbole or exaggeration when I say that Phaser 3.50 is the single biggest point release ever in the history of Phaser. There are quite literally hundreds of new features to explore, updates to key areas and of course bug fixes. I did actually try counting all the changes, but gave up after I'd reached 900 of them! Thankfully, they are, as always, meticulously detailed in the [Change Log](https://github.com/photonstorm/phaser/blob/master/CHANGELOG-v3.50.md). The changes for 3.50 actually grew so large that I had to split them out from the main Change Log and put them into their own file.
|
|
|
|
However, don't let this overwhelm you. A massive number of the changes are purely internal and while there are absolutely some API breaking changes in this release (hence the large version number jump), we've kept them as sensible as possible. We already know of lots of devs who have upgraded with minimal, or no, changes to their actual game code. We cannot guarantee that for everyone, of course, but depending on how complex your game is, the chances are good.
|
|
|
|
There is plenty to be excited about in this version. It pulls together most of the R&D that took place earlier this year for Phaser 4 and delivers it to you in version 3. New features include full support for post-processing effects via the new Post FX Pipeline, multi-texture support for faster WebGL rendering, a brand new Layer Game Object for the ability to group and post process objects without impacting their transforms, new event hooks, a massive overhaul of the Animation system, funky looking new Point Lights, a new Pipeline Manager, new Camera effects, the latest version of the Spine Plugin, an extremely powerful new Mesh Game Object, a brand new Render Texture, huge improvements to Bitmap Text, isometric and hexagonal Tilemap support, a new Pushable Arcade Physics Body type, new Geometry Intersection tests, Light 2D Updates and lots, lots, **lots** more!
|
|
|
|
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](#changelog). I assure you, it's worth while :)
|
|
|
|
I'd like to send a massive thank-you to everyone who supports [Phaser on Patreon](https://www.patreon.com/photonstorm), 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](https://www.patreon.com/photonstorm). Here you can find the latest development reports including the concepts behind Phaser 4.
|
|
|
|
You can also follow Phaser on [Twitter](https://twitter.com/phaser_) and chat with fellow Phaser devs in our [Discord](https://phaser.io/community/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!

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.
|
|
|
|
There are other benefits to [backing Phaser](https://www.patreon.com/join/photonstorm), too:
|
|
|
|
|
|
|
|
We use [Patreon](https://www.patreon.com/photonstorm) to manage the backing and you can [support Phaser](https://www.patreon.com/join/photonstorm?) 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:
|
|

|
|
npm install phaser
|
|
```
|
|
|
|
### CDN
|
|
|
|
[](https://www.jsdelivr.com/package/npm/phaser)
|
|
|
|
[Phaser is on jsDelivr](https://www.jsdelivr.com/package/npm/phaser) which is a "super-fast CDN for developers". Include the following in your html:
|
|
|
|
```html
|
|
<script src="//cdn.jsdelivr.net/npm/phaser@3.55.2/dist/phaser.js"></script>
|
|
```
|
|
|
|
or the minified version:
|
|
|
|
```html
|
|
<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](https://github.com/photonstorm/phaser/tree/master/types) 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:
|
|
|
|
```json
|
|
"typeRoots": [
|
|
"./node_modules/phaser/types"
|
|
],
|
|
"types": [
|
|
"Phaser"
|
|
]
|
|
```
|
|
|
|
We recently published a new [Phaser 3 TypeScript Project Template](https://github.com/photonstorm/phaser3-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](https://github.com/photonstorm/phaser3-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.
|
|

### 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](https://rexrainbow.github.io/phaser3-rex-notes/docs/site/index.html#list-of-my-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](https://rexrainbow.github.io/phaser3-rex-notes/docs/site/index.html)
|
|
|
|
### Create Your First Phaser 3 Example
|
|
|
|
Create an `index.html` page locally and paste the following code into it:
|
|
|
|
```html
|
|
<!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:
|
|
|
|
```javascript
|
|
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`:
|
|
|
|
```javascript
|
|
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:
|
|
|
|
```javascript
|
|
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](https://gist.github.com/photonstorm/46cb8fb4b19fc7717dcad514cdcec064))
|
|
|
|
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!

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](https://github.com/photonstorm/phaser3-custom-build#creating-custom-phaser-3-builds) 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`.
