Implementations

impl Particle

pub const fn new( x: f32, y: f32, vx: f32, vy: f32, lifetime: f32, size: f32, color: u32, ) -> Self

Creates a new particle.

pub fn update(&mut self, dt: f32) -> bool

Updates the particle position and lifetime.

Returns

True if particle is still alive

pub fn alpha(&self) -> f32

Returns the current alpha value based on remaining lifetime.

pub const fn rgb(&self) -> (f32, f32, f32)

Returns the RGB color components.
