Description copied from class: Effector

Applies this effector to the indexth particle in the supplied buffer. The effector must use the ParticleBuffer offsets to extract fields from data, for example: float x = data[start+ParticleBuffer.POS_X].

Specified by:

apply in class Effector

Parameters:

index - the index of the particle, which can be used to index into other per-particle data arrays.

data - the particle field data.

start - the offset into data at which the particle's fields start.

now - the number of seconds elapsed since the emitter came into being. Can be used to compute a particle's age.

dt - the amount of time (in fractions of a second) that has elapsed since the last update.
