class `ParticleEmitterConeShape`

Inherits: ParticleEmitterShape

Particle emitter shape that emits particles from a cone.

Particles can be created on cone base or volume, while controlling the radial arc of the emitted portion of the volume, as well as thickness of the cone emission volume. All particles will have random normals within the distribution of the cone.

Internal

Methods

SpawnInternal

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.

SpawnInternal

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

Spawns a single particle randomly, generating its position and normal.

SpawnInternal

void SpawnInternal(float t, Vector3 &position, Vector3 &normal) const

Spawns a single particle on the specified point on the cone, generating its position and normal.

Protected

Methods

CalcBounds

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

Calculates the bounds of the emitter shape.

shape: AABB for the emitter shape itself.
velocity: AABB for the generated normals.

GetPointInCone

void GetPointInCone(const Vector2 &pos2D, float distance, Vector3 &position, Vector3 &normal) const

Generates a position and normal of a particle based on the input 2D position on the cone circle base.
