Member Function Documentation

void ParticleSystem::clear_to_initial ( ) [inline]

Resets the system to its start state by resizing to 0, then resizing back to current size.

Definition at line 48 of file particleSystem.I.

void ParticleSystem::induce_labor ( ) [inline]

Forces the birth of a particle litter this frame by resetting _tics_since_birth.

Definition at line 36 of file particleSystem.I.

static void ParticleSystem::init_type ( ) [inline, static]

This function is declared non-inline to work around a compiler bug in g++ 2.96.

Making it inline seems to cause problems in the optimizer.

Reimplemented from Physical.

Definition at line 170 of file particleSystem.h.

References Physical::init_type().

void ParticleSystem::output ( ostream & out ) const [virtual]

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

Reimplemented from Physical.

Definition at line 702 of file particleSystem.cxx.

void ParticleSystem::render ( ) [inline]

Populates an attached GeomNode structure with the particle geometry for rendering.

This is a wrapper for accessability.

Definition at line 24 of file particleSystem.I.

Referenced by ParticleSystemManager::do_particles().

void ParticleSystem::soft_start ( PN_stdfloat br = 0.0 ) [inline]

Causes system to use birth rate set by set_birth_rate()

Definition at line 68 of file particleSystem.I.

void ParticleSystem::soft_stop ( PN_stdfloat br = 0.0 ) [inline]

Causes system to use birth rate set by set_soft_birth_rate()

Definition at line 83 of file particleSystem.I.

void ParticleSystem::update ( PN_stdfloat dt )

Updates the particle system.

Call once per frame.
