/** CCSprite is a 2d image ( http://en.wikipedia.org/wiki/Sprite_(computer_graphics) )
|
|
*
|
|
* CCSprite can be created with an image, or with a sub-rectangle of an image.
|
|
*
|
|
* If the parent or any of its ancestors is a CCSpriteBatchNode then the following features/limitations are valid
|
|
* - Features when the parent is a CCBatchNode:
|
|
* - MUCH faster rendering, specially if the CCSpriteBatchNode has many children. All the children will be drawn in a single batch.
|
|
*
|
|
* - Limitations
|
|
* - Camera is not supported yet (eg: CCOrbitCamera action doesn't work)
|
|
* - GridBase actions are not supported (eg: CCLens, CCRipple, CCTwirl)
|
|
* - The Alias/Antialias property belongs to CCSpriteBatchNode, so you can't individually set the aliased property.
|
|
* - The Blending function property belongs to CCSpriteBatchNode, so you can't individually set the blending function property.
|
|
* - Parallax scroller is not supported, but can be simulated with a "proxy" sprite.
|
|
*
|
|
* If the parent is an standard CCNode, then CCSprite behaves like any other CCNode:
|
|
* - It supports blending functions
|
|
* - It supports aliasing / antialiasing
|
|
* - But the rendering will be slower: 1 draw per children.
|
|
*
|
|
* The default anchorPoint in CCSprite is (0.5, 0.5).
