Struct CircleCollider 

pub struct CircleCollider {
    pub center: Point,
    pub radius: f64,
    pub response: CollisionResponse,
}

Solid circular obstacle with swept collision detection.

Fields

center: Point

Obstacle center.

radius: f64

Nonnegative obstacle radius.

response: CollisionResponse

Contact response.

Trait Implementations

impl Clone for CircleCollider

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for CircleCollider

impl Debug for CircleCollider

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl ParticleModifier for CircleCollider

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 apply_event( &self, particle: &mut Particle, step: f32, _: Time, _: &mut Random, ) -> Result<bool, ValidationError>

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

fn work(&self) -> u64

Conservative per-particle operator work charged before replay.

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.
