pixi-spine

Spine implementation for pixi v3

Usage

Browserify

If you use browserify you can use pixi-spine like this:

var PIXI = require('pixi.js'),
    spine = require('pixi-spine');

PIXI.loader
    .add('spineCharacter', 'spine-data-1/HERO.json');
    .load(function (loader, resources) {
        var animation = new spine.Spine(resources.spineCharacter.spineData);

        // add the animation to the scene and render...
    });

Prebuilt Files

If you are just including the built files, pixi spine adds itself to a pixi namespace:

PIXI.loader
    .add('spineCharacter', 'spine-data-1/HERO.json');
    .load(function (loader, resources) {
        var animation = new PIXI.spine.Spine(resources.spineCharacter.spineData);

        // add the animation to the scene and render...
    });

How to use spine events

// animation is the instantiated pixi-spine object

animation.state.onEvent = function(i, event) {
  console.log('event fired!', i, event);
};

How to choose resolution

Use with pixi-compressed-textures.js

//choose preferred resolution and texture type
PIXI.loader.before(PIXI.compressedTextures.extensionChooser(["@2x.atlas"]));
//specify what resolutions are available for spine animations
var options = { metadata: { spineMetadata: { choice: ["@.5x.atlas", "@2x.atlas"] } } };

PIXI.loader
    .add('spineCharacter', 'spine-data-1/HERO.json', options);
    .load(function (loader, resources) {
        var animation = new PIXI.spine.Spine(resources.spineCharacter.spineData);
    });

How to use compressed textures

PIXI.loader.before(PIXI.compressedTextures.extensionChooser(["@2x.atlas", ".dds"]));
var options = { metadata: { spineMetadata: { choice: ["@.5x.atlas", "@2x.atlas"] }, imageMetadata: { choice: [".dds", ".pvr"] } } };

PIXI.loader
    .add('spineCharacter', 'spine-data-1/HERO.json', options);
    .load(function (loader, resources) {
        var animation = new PIXI.spine.Spine(resources.spineCharacter.spineData);
    });

Building

You will need to have node and gulp setup on your machine.

Then you can install dependencies and build:

npm i && npm run build

That will output the built distributables to ./dist.

Typescript

Typescript definition file for pixi-spine is available in pixi-typescript
