pub fn update_params(&self, queue: &Queue, dt: f32)

pub fn spawn_particles(&self, queue: &Queue, new_particles: &[GpuParticle])

pub fn compute_pass(&self, encoder: &mut CommandEncoder, active_particles: u32)

pub fn render_pass<'a>( &'a self, rpass: &mut RenderPass<'a>, global_bind_group: &'a BindGroup, active_particles: u32, )

pub fn spawn_explosion( &self, queue: &Queue, center: [f32; 3], count: u32, base_color: [f32; 4], force: f32, )
