CPParticle

Programmable particle.

Particle is part of the particle effect animation support. Particle effect support consists of three key components:

• Particle
• Particle emitter
• Particle sprite

Particle defines a single-pixel element (a-la mini-sprite) that has its own lifecycle and gets updated on each frame update. Particle emitter is a components that is responsible for creating particles. And particle sprite ties all that together into single renderable component. Particle sprite can have one or more particle emitters and each emitter can create multiple particles. One of the key features of particle effect support is its modularity: particle implementation can be reused by multiple emitters, and an emitter implementation can be reused by multiple independent particle sprites.
