class ParticleSystem

Bases: Physical

Contains and manages a particle system.

explicit ParticleSystem(int pool_size = 0)

ParticleSystem(ParticleSystem const &copy)

Default Constructor.

Copy Constructor.

void add_spawn_template(ParticleSystem *ps)

void clear_floor_z(void)

void clear_spawn_templates(void)

void clear_to_initial(void)

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

PN_stdfloat get_tics_since_birth(void) const

void induce_labor(void)

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

void render(void)

Populates an attached GeomNode structure with the particle geometry for rendering. This is a wrapper for accessability.

void set_system_lifespan(PN_stdfloat sl)

void set_template_system_flag(bool tsf)

void soft_start(PN_stdfloat br = 0.0)

void soft_start(PN_stdfloat br, PN_stdfloat first_birth_delay)

Causes system to use birth rate set by set_birth_rate()

Causes system to use birth rate set by set_birth_rate(), with the system’s first birth being delayed by the value of first_birth_delay. Note that a negative delay is perfectly valid, causing the first birth to happen sooner rather than later.

void soft_stop(PN_stdfloat br = 0.0)

Causes system to use birth rate set by set_soft_birth_rate()

void update(PN_stdfloat dt)

virtual void write_free_particle_fifo(std::ostream &out, int indent = 0) const

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

virtual void write_spawn_templates(std::ostream &out, int indent = 0) const

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