SpriteSheetLoader Class
The sprite sheet loader is used to load in JSON sprite sheet data To generate the data you can use http://www.codeandweb.com/texturepacker and publish in the 'JSON' format There is a free version so thats nice, although the paid version is great value for money. It is highly recommended to use Sprite sheets (also know as a 'texture atlas') as it means sprites can be batched and drawn together for highly increased rendering speed. Once the data has been loaded the frames are stored in the PIXI texture cache and can be accessed though PIXI.Texture.fromFrameId() and PIXI.Sprite.fromFrameId() This loader will load the image file that the Spritesheet points to as well as the data. When loaded this class will dispatch a 'loaded' event
