/** @brief CCSpriteSheet is like a batch node: if it contains children, it will draw them in 1 single OpenGL call
|
|
* (often known as "batch draw").
|
|
*
|
|
* A CCSpriteSheet can reference one and only one texture (one image file, one texture atlas).
|
|
* Only the CCSprites that are contained in that texture can be added to the CCSpriteSheet.
|
|
* All CCSprites added to a CCSpriteSheet are drawn in one OpenGL ES draw call.
|
|
* If the CCSprites are not added to a CCSpriteSheet then an OpenGL ES draw call will be needed for each one, which is less efficient.
|
|
*
|
|
*
|
|
* Limitations:
|
|
* - The only object that is accepted as child (or grandchild) is CCSprite or any subclass of CCSprite. eg: particles, labels and layer can't be added to a CCSpriteSheet.
|
|
* - Either all its children are Aliased or Antialiased. It can't be a mix. This is because "alias" is a property of the texture, and all the sprites share the same texture.
|
|
*

* @since v0.7.1
