Member Function Documentation

do_particles() [1/2]

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 64 of file particleSystemManager.cxx.

do_particles() [2/2]

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.

virtual

Write a string representation of this instance to <out>.

remove_particlesystem()

void ParticleSystemManager::remove_particlesystem

(

ParticleSystem *

ps
