Struct IntensityOverLifetime 

pub struct IntensityOverLifetime {
    pub curve: ParticleCurve,
}

RGB energy multiplier; alpha is unchanged and HDR energy is not clipped.

Fields

curve: ParticleCurve

Multiplier over normalized lifetime.

Implementations

impl IntensityOverLifetime

pub fn new(curve: ParticleCurve) -> Self

Creates an RGB energy multiplier curve.

Trait Implementations

impl Clone for IntensityOverLifetime

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl ParticleModifier for IntensityOverLifetime

fn apply( &self, particle: &mut Particle, _: f32, _: Time, _: &mut Random, ) -> Result<(), ValidationError>

Updates one live particle; index and canonical age remain engine-owned.

fn resets_color(&self) -> bool

Requests birth-color restoration before the ordered modifier chain. Multiplicative lifetime energy curves use this to avoid frame-count accumulation.

fn work(&self) -> u64

Conservative per-particle operator work charged before replay.

fn apply_event( &self, particle: &mut Particle, step_seconds: f32, time: Time, random: &mut Random, ) -> Result<bool, ValidationError>

Optional predicted-step collision response, preserving the original callback API.
