})` * * and it will log all of the arguments your function received from the Signal. * * Sprites have lots of default signals you can listen to in their Events class, such as: * * `sprite.events.onKilled` * * Which is called automatically whenever the Sprite is killed. * There are lots of other events, see the Events component for a list. * * As well as listening to pre-defined Signals you can also create your own: * * `var mySignal = new Phaser.Signal();` * * This creates a new Signal. You can bind a callback to it: * * `mySignal.add(myCallback, this);` * * and then finally when ready you can dispatch the Signal: * * `mySignal.dispatch(your arguments);` * * And your callback will be invoked.

Assets stored in different areas of the cache can have the * same key, for example 'playerWalking' could be used as the key for both a sprite sheet and an audio file, * because they are unique data types. * * The cache is automatically populated by the Phaser.Loader. When you use the loader to pull in external assets * such as images they are automatically placed into their respective cache. Most common Game Objects, such as * Sprites and Videos automatically query the cache to extract the assets they need on instantiation. * * You can access the cache from within a State via `this.cache`. From here you can call any public method it has, * including adding new entries to it, deleting them or querying them. * * Understand that almost without exception when you get an item from the cache it will return a reference to the * item stored in the cache, not a copy of it. Therefore if you retrieve an item and then modify it, the original * object in the cache will also be updated, even if you don't put it back into the cache again. * * By default when you change State the cache is _not_ cleared, although there is an option to clear it should * your game require it. In a typical game set-up the cache is populated once after the main game has loaded and * then used as an asset store. * * @class Phaser.Cache * @constructor * @param {Phaser.Game} game - A reference to the currently running game. */ Phaser.Cache = function (game) { /** * @property {Phaser.Game} game - Local reference to game. */ this.game = game; /** * Automatically resolve resource URLs to absolute paths for use with the Cache.getURL method. * @property {boolean} autoResolveURL */ this.autoResolveURL = false; /** * The main cache object into which all resources are placed. * @property {object} _cache * @private */ this._cache = { canvas: {}, image: {}, texture: {}, sound: {}, video: {}, text: {}, json: {}, xml: {}, physics: {}, tilemap: {}, binary: {}, bitmapData: {}, bitmapFont: {}, shader: {}, renderTexture: {} }; /** * @property {object} _urlMap - Maps URLs to resources. * @private */ this._urlMap = {}; /** * @property {Image} _urlResolver - Used to resolve URLs to the absolute path. * @private */ this._urlResolver = new Image(); /** * @property {string} _urlTemp - Temporary variable to hold a resolved url. * @private */ this._urlTemp = null; /** * @property {Phaser.Signal} onSoundUnlock - This event is dispatched when the sound system is unlocked via a touch event on cellular devices. */ this.onSoundUnlock = new Phaser.Signal(); /** * @property {array} _cacheMap - Const to cache object look-up array. * @private */ this._cacheMap = []; this._cacheMap[Phaser.Cache.CANVAS] = this._cache.canvas; this._cacheMap[Phaser.Cache.IMAGE] = this._cache.image; this._cacheMap[Phaser.Cache.TEXTURE] = this._cache.texture; this._cacheMap[Phaser.Cache.SOUND] = this._cache.sound; this._cacheMap[Phaser.Cache.TEXT] = this._cache.text; this._cacheMap[Phaser.Cache.PHYSICS] = this._cache.physics; this._cacheMap[Phaser.Cache.TILEMAP] = this._cache.tilemap; this._cacheMap[Phaser.Cache.BINARY] = this._cache.binary; this._cacheMap[Phaser.Cache.BITMAPDATA] = this._cache.bitmapData; this._cacheMap[Phaser.Cache.BITMAPFONT] = this._cache.bitmapFont; this._cacheMap[Phaser.Cache.JSON] = this._cache.json; this._cacheMap[Phaser.Cache.XML] = this._cache.xml; this._cacheMap[Phaser.Cache.VIDEO] = this._cache.video; this._cacheMap[Phaser.Cache.SHADER] = this._cache.shader; this._cacheMap[Phaser.Cache.RENDER_TEXTURE] = this._cache.renderTexture; this.addDefaultImage(); this.addMissingImage(); }; /** * @constant * @type {number} */ Phaser.Cache.CANVAS = 1; /** * @constant * @type {number} */ Phaser.Cache.IMAGE = 2; /** * @constant * @type {number} */ Phaser.Cache.TEXTURE = 3; /** * @constant * @type {number} */ Phaser.Cache.SOUND = 4; /** * @constant * @type {number} */ Phaser.Cache.TEXT = 5; /** * @constant * @type {number} */ Phaser.Cache.PHYSICS = 6; /** * @constant * @type {number} */ Phaser.Cache.TILEMAP = 7; /** * @constant * @type {number} */ Phaser.Cache.BINARY = 8; /** * @constant * @type {number} */ Phaser.Cache.BITMAPDATA = 9; /** * @constant * @type {number} */ Phaser.Cache.BITMAPFONT = 10; /** * @constant * @type {number} */ Phaser.Cache.JSON = 11; /** * @constant * @type {number} */ Phaser.Cache.XML = 12; /** * @constant * @type {number} */ Phaser.Cache.VIDEO = 13; /** * @constant * @type {number} */ Phaser.Cache.SHADER = 14; /** * @constant * @type {number} */ Phaser.Cache.RENDER_TEXTURE = 15; Phaser.Cache.prototype = { ////////////////// // Add Methods // ////////////////// /** * Add a new canvas object in to the cache. * * @method Phaser.Cache#addCanvas * @param {string} key - The key that this asset will be stored in the cache under.
