Method Details

willInit

public void willInit(int count)

Called just before an initializer is used to initialize one or more particles. Gives the initializer a chance to do any computation that will be shared across all particles initialized on this frame.

init

public abstract void init(int index,
 float[] data,
 int start)

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

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.
