Struct PolygonCollider 

pub struct PolygonCollider { /* private fields */ }

Bounded simple polygon obstacle, prepared once rather than per particle.

Implementations

impl PolygonCollider

pub fn new( vertices: Arc<[Point]>, response: CollisionResponse, ) -> Result<Self, ValidationError>

Validates 3..=256 finite vertices and rejects intersecting nonadjacent edges.

Trait Implementations

impl Clone for PolygonCollider

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PolygonCollider

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

Formats the value using the given formatter.

impl ParticleModifier for PolygonCollider

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.
