Member Function Documentation

void ParticleSystemManager::do_particles ( PN_stdfloat  dt)

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.

Definition at line 74 of file particleSystemManager.cxx.

References ParticleSystem::render(), and ParticleSystem::update().

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

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.
