Member Function Documentation

getBlendFunc()

virtual ccBlendFunc getBlendFunc ( void  )

pure virtual

Returns the blending function that is currently being used.

Returns

A ccBlendFunc structure with source and destination factor which specified pixel arithmetic.

Implemented in CCAtlasNode, CCLayerColor, CCMotionStreak, CCParticleBatchNode, CCParticleSystem, CCSprite, and CCSpriteBatchNode.

setBlendFunc()

virtual void setBlendFunc ( ccBlendFunc  blendFunc )

pure virtual

Sets the source blending function.

Parameters

blendFunc

A structure with source and destination factor to specify pixel arithmetic, e.g. {GL_ONE, GL_ONE}, {GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA}.

Implemented in CCMotionStreak, CCParticleBatchNode, CCSprite, CCSpriteBatchNode, CCAtlasNode, CCLayerColor, and CCParticleSystem.
