Attributes of a Particle System: - emission rate of the particles - Gravity Mode (Mode A): - gravity - direction - speed +- variance - tangential acceleration +- variance - radial acceleration +- variance - Radius Mode (Mode B): - startRadius +- variance - endRadius +- variance - rotate +- variance - Properties common to all modes: - life +- life variance - start spin +- variance - end spin +- variance - start size +- variance - end size +- variance - start color +- variance - end color +- variance - life +- variance - blending function - texture Cocos2d also supports particles generated by Particle Designer (http://particledesigner.71squared.com/). 'Radius Mode' in Particle Designer uses a fixed emit rate of 30 hz. Since that can't be guaranteed 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 ParticleSystemQuad) - 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.
