Expand description

State for a single live particle.

Fields§

§position: Point3<f32>

Current world-space position.

§velocity: Vector3<f32>

Current velocity (world units/second).

§acceleration: Vector3<f32>

Constant per-particle acceleration (applied in addition to gravity).

§color_start: Rgb565

Colour at birth (t = 0).

§color_end: Rgb565

Colour at death (t = 1).

§size_start: f32

Billboard half-size at birth.

§size_end: f32

Billboard half-size at death. Use 0.0 to shrink out.

§age: f32

Elapsed lifetime in seconds.

§lifetime: f32

Total lifetime in seconds.

Implementations§

impl Particle
