|
|
* 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 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 texture atlas') as it means sprite's 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.fromFromeId()
|
|
* This loader will also load the image file that the Spritesheet points to as well as the data.
|
|
* When loaded this class will dispatch a 'loaded' event
|
|
* @class SpriteSheetLoader
|
|
* @extends EventTarget
|
|
* @constructor
|
|
* @param url {String} the url of the sprite sheet JSON file
