Struct ColorOverLife

Source

pub struct ColorOverLife {
    pub birth_color: [f32; 4],
    pub death_color: [f32; 4],
    pub max_life: f32,
}

Expand description

Lerps a particle’s color from birth_color to death_color over its life.

Fields§

§birth_color: [f32; 4]

Color when the particle is born (life == max_life).

§death_color: [f32; 4]

Color when the particle is about to die (life → 0).

§max_life: f32

The initial (maximum) lifetime used to compute normalised age.

Implementations§

Source §

impl ColorOverLife

Source

pub fn new(birth_color: [f32; 4], death_color: [f32; 4], max_life: f32) -> Self

Create a new color-over-life modifier.

Source

pub fn apply(&self, particle: &mut GpuParticle)

Update the color of a single particle based on remaining life.

Source

pub fn apply_all(&self, particles: &mut [GpuParticle])

Update colors for all alive particles.
