ParticleSystemManager

class ParticleSystemManager

Manages a set of individual ParticleSystem objects, so that each individual one doesn’t have to be updated and rendered every frame See Also : particleSystemManager.cxx

default constructor

void attach_particlesystem(ParticleSystem *ps)

void clear(void)

void do_particles(PN_stdfloat dt)

void do_particles(PN_stdfloat dt, ParticleSystem *ps, bool do_render = true)

does an update and render for each ps in the list. this is probably the one you want to use. Rendering is the expensive operation, and particles REALLY should at least be updated every frame, so nth_frame stepping applies only to rendering.

does an update and an optional render for a specific ps. Since rendering is the expensive operation, multiple updates could be applied before calling the final render.
