# 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](https://github.com/photonstorm/phaser-ce). 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](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.
|
|
|
|
Thousands of developers from indie and multi-national digital agencies, and universities worldwide use Phaser. You can take a look at their incredible [games](https://phaser.io/games/).

|
**Updated:** Thank you to everyone who has been trying out Phaser 3 and help us improve it. Today we released version 3.2.1, full of updates and bug fixes. Check out the [Change Log](#changelog) 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](https://phaser.io/phaser3/devlog) in the weekly [Phaser World](https://phaser.io/community/newsletter) newsletter. Subscribe to stay in touch and get all the latest news from us and the wider Phaser community.

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!

### 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](http://labs.phaser.io), or clone the [examples repo][examples]. 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:
|
|
|
|
```html
|
|
<!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:
|
|
|
|
```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('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:
|
|
|
|
```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:

|
|
|
|
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 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 3.2.1 - 12th March 2018
|
|
|
|
### Bug Fixes
|
|
|
|
* Fixed issue with Render Texture tinting. Fix #3336 (thanks @rexrainbow)
|
|
* Fixed Utils.String.Format (thanks @samme)
|
|
* The Matter Debug Layer wouldn't clear itself in canvas mode. Fix #3345 (thanks @samid737)
|
|
* TimerEvent.remove would dispatch the Timer event immediately based on the opposite of the method argument, making it behave the opposite of what was expected. It now only fires when requested (thanks @migiyubi)
|
|
* The TileSprite Canvas Renderer did not support rotation, scaling or flipping. Fix #3231 (thanks @TCatshoek)
|
|
* Fixed Group doesn't remove children from Scene when cleared with the `removeFromScene` argument set (thanks @iamchristopher)
|
|
* Fixed an error in the lights pipeline when no Light Manager has been defined (thanks @samme)
|
|
* The ForwardDiffuseLightPipeline now uses `sys.lights` instead of the Scene variable to avoid errors due to injection removal.
|
|
* Phaser.Display.Color.Interpolate would return NaN values because it was loading the wrong Linear function. Fix #3372 (thanks @samid737)
|
|
* RenderTexture.draw was only drawing the base frame of a Texture. Fix #3374 (thanks @samid737)
|
|
* TileSprite scaling differed between WebGL and Canvas. Fix #3338 (thanks @TCatshoek)
|
|
* Text.setFixedSize was incorrectly setting the `text` property instead of the `parent` property. Fix #3375 (thanks @rexrainbow)
|
|
* RenderTexture.clear on canvas was using the last transform state, instead of clearing the whole texture.
|
|
|
|
### Updates
|
|
|
|
* The SceneManager.render will now render a Scene as long as it's in a LOADING state or higher. Before it would only render RUNNING scenes, but this precluded those that were loading assets.
|
|
* A Scene can now be restarted by calling `scene.start()` and providing no arguments (thanks @migiyubi)
|
|
* The class GameObject has now been exposed, available via `Phaser.GameObjects.GameObject` (thanks @rexrainbow)
|
|
* A Camera following a Game Object will now take the zoom factor of the camera into consideration when scrolling. Fix #3353 (thanks @brandonvdongen)
|
|
* Calling `setText` on a BitmapText object will now recalculate its display origin values. Fix #3350 (thanks @migiyubi)
|
|
* You can now pass an object to Loader.atlas, like you you can with images. Fix #3268 (thanks @TCatshoek)
|
|
* The `onContextRestored` callback won't be defined any more unless the WebGL Renderer is in use in the following objects: BitmapMask, Static Tilemap, TileSprite and Text. This should allow those objects to now work in HEADLESS mode. Fix #3368 (thanks @16patsle)
|
|
* The SetFrame method now has two optional arguments: `updateSize` and `updateOrigin` (both true by default) which will update the size and origin of the Game Object respectively. Fix #3339 (thanks @Jerenaux)
