Struct ParticleSystem 

pub struct ParticleSystem {
    pub buffer: ParticleBuffer,
    pub emitters: Vec<ParticleEmitter>,
    pub gravity: GravityForce,
    pub drag: DragForce,
    pub floor: Option<FloorCollision>,
    pub rng: SimpleRng,
    pub time: f32,
}

High-level particle system that owns a buffer, emitters, and forces.

Fields

buffer: ParticleBuffer

The SoA particle data.

emitters: Vec<ParticleEmitter>

All registered emitters.

gravity: GravityForce

Global gravity.

drag: DragForce

Global drag.

floor: Option<FloorCollision>

Optional floor collision plane.

rng: SimpleRng

Internal RNG for emitter seeding.

time: f32

Elapsed simulation time.

Implementations

impl ParticleSystem

pub fn new(capacity: usize) -> Self

Create a new particle system with the given buffer capacity.

pub fn add_emitter(&mut self, emitter: ParticleEmitter) -> usize

Register an emitter and return its index.

pub fn step(&mut self, dt: f32)

Advance the simulation by dt seconds.

Order: emit → gravity → drag → floor → integrate.
