Implementations

impl ParticlePool

pub fn new(capacity: usize) -> Self

pub fn spawn(&mut self, particle: MathParticle) -> bool

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

pub fn apply_field(&mut self, field: &ForceField, time: f32)

Apply a force field to all particles that have AFFECTED_BY_FIELDS.

pub fn apply_force(&mut self, force: Vec3)

Apply an explicit force to all particles (e.g. gravity, wind).

pub fn apply_gravity(&mut self, g: f32)

Apply gravity to all GRAVITY-flagged particles.

pub fn collide_floor(&mut self, restitution: f32)

Collide all COLLIDES particles against an infinite floor at y=0.

pub fn clear(&mut self)

Kill all particles immediately.

pub fn iter(&self) -> impl Iterator<Item = &MathParticle>

pub fn iter_mut(&mut self) -> impl Iterator<Item = &mut MathParticle>

pub fn count(&self) -> usize

pub fn capacity(&self) -> usize

pub fn is_full(&self) -> bool

pub fn export_gpu_buffer(&self) -> Vec<f32>

Export live particle positions to a flat f32 buffer (x,y,z, r,g,b,a per particle).
