Detailed Description 细节描述
CCSprite is a 2d image ( http://en.wikipedia.org/wiki/Sprite_(computer_graphics) )
精灵是一个2D图象
CCSprite can be created with an image, or with a sub-rectangle of an image.
精灵能够通过一个图片或图片中的一个区域来创建
If the parent or any of its ancestors is a CCSpriteBatchNode then the following features/limitations are valid
如果其父或者祖先是CCSpriteBatchNode 那么遵循以下特征和限制
- 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.
- 当其父为一个CCBatchNode 尤其是 CCSpriteBatchNode 拥有多个孩子，它拥有更快的绘制速度。所有的孩子将一次性绘制。
- Limitations
- Camera is not supported yet (eg: CCOrbitCamera action doesn't work)镜头无法使用
- GridBase actions are not supported (eg: CCLens, CCRipple, CCTwirl) 网格动作无法使用
- The Alias/Antialias property belongs to CCSpriteBatchNode, so you can't individually set the aliased property.Alias/Antialias
- 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.视差滚动不支持
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.
//============================================================================
| bool isFlipX | ( | void | ) |
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->setScaleX(sprite->getScaleX() * -1);
| bool isFlipY | ( | void | ) |
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->setScaleY(sprite->getScaleY() * -1);
//========================================================================================
| void setDisplayFrameWithAnimationName | ( | const char * | animationName, |
| int | frameIndex | ||
| ) |
changes the display frame with animation name and index.
The animation name will be get from the CCAnimationCache
- Since:
- v0.99.5
| void setFlipX | ( | bool | bFlipX | ) |
| void setFlipY | ( | bool | bFlipY | ) |
| void setHonorParentTransform | ( | ccHonorParentTransform | eHonorParentTransform | ) | [inline] |
whether or not to transform according to its parent transformations.
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 CCSpriteSheet.
