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, and @rolnaaba) and we will keep you posted! You can also check back on our site as any breakthroughs will be posted up there too!

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 degredation 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!

Basic Usage Example

// You can use either `new PIXI.WebGLRenderer`, `new PIXI.CanvasRenderer`, or `PIXI.autoDetectRenderer`
// which will try to choose the best renderer for the environment you are in.
var renderer = new PIXI.WebGLRenderer(800, 600);

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

// You need to create a root container that will hold the scene you want to draw.
var stage = new PIXI.Container();


// Declare a global variable for our sprite so that the animate function can access it.
var bunny = null;

// load the texture we need
PIXI.loader.add('bunny', 'bunny.png').load(function (loader, resources) {
    // This creates a texture from a 'bunny.png' image.
    bunny = new PIXI.Sprite(resources.bunny.texture);

    // Setup the position and scale of the bunny
    bunny.position.x = 400;
    bunny.position.y = 300;

    bunny.scale.x = 2;
    bunny.scale.y = 2;

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

    // kick off the animation loop (defined below)
    animate();
});

function animate() {
    // start the timer for the next animation loop
    requestAnimationFrame(animate);

    // each frame we spin the bunny around a bit
    bunny.rotation += 0.01;

    // this is the main render call that makes pixi draw your container and its children.
    renderer.render(stage);
}

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. Once you do, you can then install the gulp executable:

$> npm install -g gulp

Then, in the folder where you have cloned the repository, install the build dependencies using npm:

$> npm install

Then, to build the source, run:

$> gulp build

This will create a minified version at bin/pixi.min.js and a non-minified version at bin/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:

$> gulp build --exclude extras --exclude interaction

You can also use the short-form -e:

$> gulp build -e extras -e interaction -e filters

How to generate the documentation

The docs can be generated using npm:

$> npm run docs

There is also a gulp task to generate them if you want to:

$> gulp jsdoc

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