/** @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
|
|
