action sorts

The actions of the system can be sorted into these kinds at physical standpoint:

1. offest position.This makes all vertices of a particle offest the same position.
   • this kind contains:VelocityGlobal(Local),AccelerateGlobal(Local),OffestPositionLocal,DriftLocal…
2. rotation.This makes each vertices of a particles offest a different position.
   • this kind contains:RandomRotateLocal,AutoRotateGlobal,AlwayFaceToCameraGlobal…
3. scale.This makes each vertices of a particles offest a different position.
   • this kind contains:RandomScaleLocal,ScaleByLifeGlobal,ScaleByTimeGlobal…
4. color.This influences a particle’s color.
   • this kind contains:FlickerGlobal,ChangeColorByLifeGlobal,RandomColorLocal…
