/** @brief Particle System base class.
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 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. Example:
@code
emitter.radialAccel = 15;
emitter.startSpin = 0;
@endcode
