Class Detail

cc.Sprite()

cc.Sprite is a 2d image ( http://en.wikipedia.org/wiki/Sprite_(computer_graphics) )
cc.Sprite can be created with an image, or with a sub-rectangle of an image.
If the parent or any of its ancestors is a cc.SpriteBatchNode then the following features/limitations are valid
- Features when the parent is a cc.BatchNode:
- MUCH faster rendering, specially if the cc.SpriteBatchNode 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 cc.Node, then cc.Sprite behaves like any other cc.Node:
- It supports blending functions
- It supports aliasing / antialiasing
- But the rendering will be slower: 1 draw per children.
The default anchorPoint in cc.Sprite is (0.5, 0.5).

var aSprite = new cc.Sprite();
aSprite.initWithFile("HelloHTML5World.png",cc.rect(0,0,480,320));
