Struct RadialForce 

pub struct RadialForce {
    pub center: Point,
    pub strength: f32,
    pub radius: f32,
    pub falloff: ForceFalloff,
}

Radius-bounded attraction/repulsion using an explicit attenuation policy.

Fields

center: Point

Force center.

strength: f32

Signed acceleration scale.

radius: f32

Finite positive influence radius.

falloff: ForceFalloff

Spatial attenuation.

Trait Implementations

impl Clone for RadialForce

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 RadialForce

fn apply( &self, particle: &mut Particle, step: 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.
