Contains and manages a particle system.

Inheritance diagram

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.

bool get_system_grows_older_flag(void) const¶

PN_stdfloat get_system_lifespan(void) const¶

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_active_system_flag(bool a)¶

void set_birth_rate(PN_stdfloat new_br)¶

void set_emitter(BaseParticleEmitter *e)¶

void set_factory(BaseParticleFactory *f)¶

void set_floor_z(PN_stdfloat z)¶

void set_litter_size(int new_ls)¶

void set_litter_spread(int new_ls)¶

void set_local_velocity_flag(bool lv)¶

void set_pool_size(int size)¶: accessqueries

void set_render_parent(PandaNode *node)¶

void set_render_parent(NodePath const &node)¶

void set_renderer(BaseParticleRenderer *r)¶

void set_soft_birth_rate(PN_stdfloat new_br)¶

void set_spawn_on_death_flag(bool sod)¶

void set_spawn_render_node(PandaNode *node)¶

void set_spawn_render_node_path(NodePath const &node)¶

void set_system_age(PN_stdfloat age)¶

void set_system_grows_older_flag(bool sgo)¶

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>.
