'Radius Mode' in Particle Designer uses a fixed emit rate of 30 hz. Since that can't be guarateed in cocos2d, cocos2d uses a another approach, but the results are almost identical. cocos2d supports all the variables used by Particle Designer plus a bit more: - spinning particles (supported when using CCParticleSystemQuad) - tangential acceleration (Gravity mode) - radial acceleration (Gravity mode) - radius direction (Radius mode) (Particle Designer supports outwards to inwards direction only) It is possible to customize any of the above mentioned properties in runtime.
