static RTTIType *GetRttiStatic()

RTTIType *GetRtti() const override

Returns an interface you can use to access class' Run Time Type Information.

u32 SpawnInternal(const Random &random, ParticleSet &particles, u32 count, const ParticleSystemState &state) const override

Spawns a new set of particles using the current shape's distribution.

random: Random number generator.
particles: Particle set in which to insert new particles.
count: Number of particles to spawn.
state: Optional state that can contain various per-frame information required for spawning the particles.

Returns: Index at which the first of the particles was inserted, with other particles following sequentially.

void SpawnInternal(const Random &random, Vector3 &position, Vector3 &normal) const

Spawns a single particle, generating its position and normal.

void CalcBounds(AABox &shape, AABox &velocity) const override

Calculates the bounds of the emitter shape.
