Inline docs Build Status

The aim of this project is to provide a fast lightweight 2D library that works across all devices. The Pixi renderer allows everyone to enjoy the power of hardware acceleration without prior knowledge of WebGL. Also, it's fast. Really fast.

If you want to keep up to date with the latest pixi.js news then feel free to follow us on twitter (@doormat23, @rolnaaba, @bigtimebuddy, @ivanpopelyshev) and we will keep you posted! You can also check back on our site as any breakthroughs will be posted up there too!

Your support helps us make Pixi.js even better. Make your pledge on Patreon and we'll love you forever!

What to Use Pixi.js for and When to Use It

Pixi.js is a rendering library that will allow you to create rich, interactive graphics, cross platform applications, and games without having to dive into the WebGL API or deal with browser and device compatibility.

Pixi.js has full WebGL support and seamlessly falls back to HTML5's canvas if needed. As a framework, Pixi.js is a fantastic tool for authoring interactive content, especially with the move away from Adobe Flash in recent years. Use it for your graphics rich, interactive websites, applications, and HTML5 games. Out of the box cross-platform compatibility and graceful degradation mean you have less work to do and have more fun doing it! If you want to create polished and refined experiences relatively quickly, without delving into dense, low level code, all while avoiding the headaches of browser inconsistencies, then sprinkle your next project with some Pixi.js magic!

Boost your development and feel free to use your imagination!

Setup

It's easy to get started with Pixi.js! Simply grab the pre-built versions from here:

Release Branch - Nice and stable Pixi.js

Develop Branch - The bleeding edge version of Pixi.js

Alternatively, Pixi.js can be installed with Bower, npm or simply using a content delivery network (CDN) URL to embed Pixi.js directly on your HTML page.

Bower Install

$> bower install pixi.js

NPM Install

$> npm install pixi.js

CDN Install (via cdnjs)

<script src="https://cdnjs.cloudflare.com/ajax/libs/pixi.js/4.2.2/pixi.min.js"></script>

Note: 4.2.2 can be replaced by any released version.

Demos

Thanks to @photonstorm for providing those last 2 examples and allowing us to share the source code :)

Basic Usage Example

// The application will create a renderer using WebGL, if possible,
// with a fallback to a canvas render. It will also setup the ticker
// and the root stage PIXI.Container.
var app = new PIXI.Application();

// The application will create a canvas element for you that you 
// can then insert into the DOM.
document.body.appendChild(app.view);

// load the texture we need
PIXI.loader.add('bunny', 'bunny.png').load(function(loader, resources) {

    // This creates a texture from a 'bunny.png' image.
    var bunny = new PIXI.Sprite(resources.bunny.texture);

    // Setup the position of the bunny
    bunny.x = app.renderer.width / 2;
    bunny.y = app.renderer.height / 2;

    // Rotate around the center
    bunny.anchor.x = 0.5;
    bunny.anchor.y = 0.5;

    // Add the bunny to the scene we are building.
    app.stage.addChild(bunny);

    // Listen for frame updates
    app.ticker.add(function() {
         // each frame we spin the bunny around a bit
        bunny.rotation += 0.01;
    });
});

How to build

Note that for most users you don't need to build this project. If all you want is to use pixi, then just download one of our prebuilt releases. Really the only time you should need to build pixi.js is if you are developing it.

If you don't already have Node.js and NPM, go install them. Then, in the folder where you have cloned the repository, install the build dependencies using npm:

$> npm install

Then, to build the source, run:

$> npm run dist

This will create a minified version at dist/pixi.min.js and a non-minified version at dist/pixi.js with all the plugins in the pixi.js project.

If there are specific plugins you don't want, say "interaction" or "extras", you can exclude those:

$> npm run dist -- --exclude extras --exclude interaction

You can also use the short-form -e:

$> npm run dist -- -e extras -e interaction -e filters

How to generate the documentation

The docs can be generated using npm:

$> npm run docs

The documentation uses Jaguar.js and the jsdoc format, the configuration file can be found at scripts/jsdoc.conf.json
