a Spine 4.x plugin implementation for melonJS 2

Note: although functional, this plugin is still a work in progress. Feedback and especially contributions are welcome!

this plugin is already bundled with the required Spine 4.x runtime, so there is no need to install it separately.

Note: this plugin requires melonJS version 15.12 or higher.

To install the plugin using npm :

$ [sudo] npm install @melonjs/spine-plugin

Then import and use the plugin in your project. For example:

import { SpinePlugin } from '@melonjs/spine-plugin';
import * as me from 'melonjs';

// register the plugin
me.plugin.register(SpinePlugin);

// prepare/declare assets for the preloader
const DataManifest = [
    {
        "name": "alien-ess.json",
        "type": "spine",
        "src": "data/spine/alien-ess.json"
    },
    {
        "name": "alien.atlas",
        "type": "spine",
        "src": "data/spine/alien.atlas"
    },
];

// import default Spine class
import Spine from '@melonjs/spine-plugin';

// preload assets
me.loader.preload(DataManifest, async function() {

    // create a new Spine Renderable
    let spineAlien = new Spine(100, 100, {atlasFile: "alien.atlas", jsonFile: "alien-ess.json"});

    // set default animation
    spineAlien.setAnimation(0, "death", true);

    // add it to the game world
    me.game.world.addChild(spineAlien);

}

Note: use "spine" as a value for the type property to indicate which assets and are actual Spine assets and to be loaded using the plugin (requires version 1.4.0 or higher of the Spine plugin)

for more details, see a complete usage example in the test folder

below is the compatibility version matrix :

Note: the current version of the spine-plugin is bundled with the 4.2.x beta version of the Spine runtime, which is for now backward compatible with the Spine 4.1 runtime (from a player/rendering point of view).
