Extends RawAsset

Module: cc

Class for sprite atlas handling.

Properties
Methods
  • getTexture Returns the texture of the sprite atlas
  • getSpriteFrame Returns the sprite frame correspond to the given key in sprite atlas.
  • getSpriteFrames Returns the sprite frames in sprite atlas.
  • destroy Destroy this Object, and release all its own references to other objects.
    Actual object destruction will delayed until before rendering.
    After destroy, this CCObject is not usable any more. You can use cc.isValid(obj) to check whether the object is destroyed before accessing it.
  • _destruct Clear all references in the instance.

NOTE: this method will not clear the getter or setter functions which defined in the instance of CCObject. You can override the _destruct method if you need, for example: _destruct: function () { for (var key in this) { if (this.hasOwnProperty(key)) { switch (typeof this[key]) { case 'string': this[key] = ''; break; case 'object': case 'function': this[key] = null; break; } } }

  • _onPreDestroy Called before the object being destroyed.
  • _serialize The customized serialization for this object. (Editor Only)
  • _deserialize Init this object from the custom serialized data.
