void ParticleSystemManager::attach_particlesystem (  ParticleSystem *  ps  )  [inline]

Definition at line 54 of file particleSystemManager.I. References _ps_list, and INLINE.

void ParticleSystemManager::clear (  void   )  [inline]

Definition at line 71 of file particleSystemManager.I.

void ParticleSystemManager::do_particles (  float  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.
