/** CCPointParticleSystem is a subclass of CCParticleSystem
|
|
Attributes of a Particle System:
|
|
* All the attributes of Particle System
|
|
|
|
Features:
|
|
* consumes small memory: uses 1 vertex (x,y) per particle, no need to assign tex coordinates
|
|
* size can't be bigger than 64
|
|
* the system can't be scaled since the particles are rendered using GL_POINT_SPRITE
|
|
|
|
Limitations:
|
|
* On 3rd gen iPhone devices and iPads, this node performs MUCH slower than CCQuadParticleSystem.
