ParticleSystem

ParticleSystem ⟵ Object3D

Spawns particles in a box, moves them linearly, draws as Points (GX_POINTS). Derives from Object3D so you can scene->add(ps). Add to scene, call addParticles() and update(dt) each frame.

Methods

ParticleSystem()

Construct particle system with getDefaultSettings()

ParticleSystem(const ParticleSettings& settings)

Construct particle system (placeable; add to scene with scene->add(ps))

settings

DTO with bounds, life, velocity, size, color, maxCount, rate

void addParticles(u32 count)

Spawn count new particles within bounds

count

Number of particles to spawn

void update(f32 dt)

Advance simulation by dt: optional spawn, age, move, upload to Points

dt

Delta time in seconds

Points* getPoints() const

Get the Points object used for rendering (GX_POINTS)

static ParticleSettings getDefaultSettings()

Returns DTO with default values (compatible with Points / GX_POINTS)
