/** CCParticleBatchNode is like a batch node: if it contains children, it will draw them in 1 single OpenGL call
|
|
* (often known as "batch draw").
|
|
*
|
|
* A CCParticleBatchNode can reference one and only one texture (one image file, one texture atlas).
|
|
* Only the CCParticleSystems that are contained in that texture can be added to the CCSpriteBatchNode.
|
|
* All CCParticleSystems added to a CCSpriteBatchNode are drawn in one OpenGL ES draw call.
|
|
* If the CCParticleSystems are not added to a CCParticleBatchNode then an OpenGL ES draw call will be needed for each one, which is less efficient.
|
|
*
|
|
*
|
|
* Limitations:
|
|
* - At the moment only CCParticleSystemQuad is supported
|
|
* - All systems need to be drawn with the same parameters, blend function, aliasing, texture
|
|
*
|
|
* Most efficient usage
|
|
* - Initialize the ParticleBatchNode with the texture and enough capacity for all the particle systems
|
|
* - Initialize all particle systems and add them as child to the batch node
