Sprite Kit 与 cocos 2d的对比• 内嵌入 ios系统中

• 很好的支持纹理和粒子效果

• 很多其他引擎无法做到的事情，（视频）

• 可移植性不好

• 对 OPENGL的支持不好

Sprite kit 中的基本类

• SKView

• SKScene

• SKNode

• SKSpriteNode

SKSpriteNode SKScene

SKView

SKTexture

• + (SKTexture *)textureWithImageNamed:(NSString *)name

• + (SKTexture *)textureWithRect:(CGRect)rect inTexture:

(SKTexture *)texture

• + (SKTexture *)textureWithCGImage:(CGImageRef)image

SKTextureAtlas

• + (SKTextureAtlas *)atlasNamed:(NSString *)name

• - (SKTexture *)textureNamed:(NSString *)name

SKNode

• Position

• xScale

• yScale

• Alpha

• Paused

• Hidden

• userInteractionEnabl

ed

• Parent

• Children

• + (instancetype)node

• - (void)addChild:(SKNode *)node

• (void)removeFromParent

• (void)removeAllActions

• - (BOOL)containsPoint:(CGPoint)p

SKSpriteNode

• anchorPoint

• size

• + (instancetype)spriteNodeWithTexture:(SKTexture *)texture

size:

• + (instancetype)spriteNodeWithTexture:(SKTexture

*)textureSKNode

• + (instancetype)spriteNodeWithImageNamed:(NSString *)name

• + (instancetype)spriteNodeWithColor:(SKColor *)color size:

(CGSize)size
