Fields

position: [f32; 3]

World-space spawn origin.

shape: EmitterShape

Emitter shape.

mode: EmissionMode

Emission mode.

initial_velocity: [f32; 3]

Base initial velocity.

lifetime: f32

Particle lifetime (seconds).

mass: f32

Particle mass.

active: bool

Whether emitter is active.

accumulator: f32

Fractional accumulator for continuous mode.

Implementations

impl GpuParticleEmitter

pub fn new_continuous(position: [f32; 3], rate: f32, lifetime: f32) -> Self

Create a new emitter with a point shape and continuous mode.

pub fn new_burst(position: [f32; 3], count: usize, lifetime: f32) -> Self

Create a burst emitter.

pub fn emit(&mut self, buffer: &mut ParticleBuffer, dt: f32) -> usize

Emit particles into a buffer for one timestep dt.

pub fn burst_count(&self) -> usize

Number of particles this emitter will emit in one burst (or 0 if continuous).
