Scene Files Payload

//  Files specified in the Scene config files payload
//  will be loaded in *before* the Scene is started,
//  meaning they're available before even the Scene.preload function (if set) is called

//  This is perfect for loading in small JSON config files for example,
//  or a tiny amount of preloader assets that the preloader itself needs to use.

var sceneConfig = {
    preload: preload,
    create: create,
    pack: {
        files: [
            { type: 'image', key: 'sonic', url: 'assets/sprites/sonic_havok_sanity.png' },
            { type: 'atlas', key: 'megaset', textureURL: 'assets/atlas/megaset-0.png', atlasURL: 'assets/atlas/megaset-0.json'}
        ]
    }
};
