Method Details

sort

public abstract <T extends ParticleControllerRenderData>
int[] sort(Array<T> renderData)

Returns:

an array of offsets where each particle should be put in the resulting mesh (also if more than one mesh will be generated, this is an absolute offset considering a BIG output array).

setCamera

public void setCamera(Camera camera)

ensureCapacity

public void ensureCapacity(int capacity)

This method is called when the batch has increased the underlying particle buffer. In this way the sorter can increase the data structures used to sort the particles (i.e increase backing array size)
