Member Function Documentation

virtual void iEmitState::AddAge ( int time,

const csColor & color,

float alpha,

float swirl,

float rotspeed,

float scale

) [pure virtual]

Add an aging moment, they are interpolated.
time is the time since creation of the particle in msec. color is a gouraud color to set the particle to. (0..1) alpha can be used to make the particles transparent. the value 0 is a solid particle, the value 1 is an invisible particle the swirl value gives a swirlyness of the movement of the particle. rotspeed is the rotationspeed of the particle (per second). scale is the size of the particle at the time

virtual int iEmitState::GetAgingCount ( ) [pure virtual]

Get the number of aging moments.

virtual void iEmitState::GetAgingMoment ( int i,
