ldk_particle_emitter_clear

Remove all live particles without stopping scheduled emission.

LDK_API void ldk_particle_emitter_clear(LDKParticleEmitter *emitter);

ldk_particle_emitter_emit_bursts

Play the configured burst parameters for exactly count bursts.

LDK_API bool ldk_particle_emitter_emit_bursts(
 LDKParticleEmitter *emitter,
 u32 count
);

ldk_particle_emitter_emit_for

Play the configured emission rate for the specified duration.

LDK_API bool ldk_particle_emitter_emit_for(
 LDKParticleEmitter *emitter,
 float seconds
);

ldk_particle_emitter_make_default

Create default settings for particle emitter.

LDK_API LDKParticleEmitter ldk_particle_emitter_make_default(void);

ldk_particle_emitter_play

Start the configured mode if not playing.

LDK_API bool ldk_particle_emitter_play(LDKParticleEmitter *emitter);

ldk_particle_emitter_restart

Restart the configured mode without killing existing particles.

LDK_API bool ldk_particle_emitter_restart(LDKParticleEmitter *emitter);

ldk_particle_emitter_stop

Stop future emission; live particles continue simulating.

LDK_API void ldk_particle_emitter_stop(LDKParticleEmitter *emitter);
