Detailed Description

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).

sets a new display frame to the CCSprite.

- (void) setDisplayFrameWithAnimationName: (NSString *)  animationName

Creates an sprite with a CGImageRef and a key. The key is used by the CCTextureCache to know if a texture was already created with this CGImage. For example, a valid key is: "sprite_frame_01". If key is nil, then a new texture will be created each time by the CCTextureCache.

Since:

Property Documentation

- (NSUInteger) atlasIndex [read, write, assign]

The index used on the TextureAtlas. Don't modify this value unless you know what you are doing

- (CCSpriteBatchNode*) batchNode [read, write, assign]

weak reference to the CCSpriteBatchNode that renders the CCSprite

- (ccBlendFunc) blendFunc [read, write, assign]

conforms to CCTextureProtocol protocol

- (ccColor3B) color [read, write, assign]

RGB colors: conforms to CCRGBAProtocol protocol

- (BOOL) dirty [read, write, assign]

whether or not the Sprite needs to be updated in the Atlas

- (BOOL) flipX [read, write, assign]

whether or not the sprite is flipped horizontally. It only flips the texture of the sprite, and not the texture of the sprite's children. Also, flipping the texture doesn't alter the anchorPoint. If you want to flip the anchorPoint too, and/or to flip the children too use:

sprite.scaleX *= -1;

- (BOOL) flipY [read, write, assign]

whether or not the sprite is flipped vertically. It only flips the texture of the sprite, and not the texture of the sprite's children. Also, flipping the texture doesn't alter the anchorPoint. If you want to flip the anchorPoint too, and/or to flip the children too use:

sprite.scaleY *= -1;

- (ccHonorParentTransform) honorParentTransform [read, write, assign]

whether or not to transform according to its parent transfomrations. Useful for health bars. eg: Don't rotate the health bar, even if the parent rotates. IMPORTANT: Only valid if it is rendered using an CCSpriteBatchNode.

Since:
v0.99.0
- (CGPoint) offsetPositionInPixels [read, assign]

offset position in pixels of the sprite in points. Calculated automatically by editors like Zwoptex.

Since:
v0.99.0
- (GLubyte) opacity [read, write, assign]

opacity: conforms to CCRGBAProtocol protocol

- (ccV3F_C4B_T2F_Quad) quad [read, assign]

the quad (tex coords, vertex coords and color) information

- (CCTextureAtlas*) textureAtlas [read, write, assign]

weak reference of the CCTextureAtlas used when the sprite is rendered using a CCSpriteBatchNode

- (CGRect) textureRect [read, assign]

returns the rect of the CCSprite in points

- (BOOL) textureRectRotated [read, assign]

returns whether or not the texture rectangle is rotated

- (BOOL) usesBatchNode [read, write, assign]

whether or not the Sprite is rendered using a CCSpriteBatchNode

- (BOOL) useTrimmedFrameForAnchorPoint [read, write, assign]

normally the original frame size is used to determine the anchorPoint, but when using different offsets and same original frame sizes the ap will be off. Same for frames with different sizes and different offsets.
