Struct rapier2d::geometry::InteractionGraph

pub struct InteractionGraph<N, E> { /* fields omitted */ }

A graph where nodes are collision objects and edges are contact or proximity algorithms.

Implementations

impl<N: Copy, E> InteractionGraph<N, E>

pub fn new() -> Self

Creates a new empty collection of collision objects.

pub fn raw_graph(&self) -> &Graph<N, E>

The underlying raw graph structure of this interaction graph.

pub fn interactions(&self) -> impl Iterator<Item = &E>

All the interactions on this graph.

pub fn interactions_with_endpoints(&self) -> impl Iterator<Item = (N, N, &E)>

All the interactions on this graph with the corresponding endpoint weights.

pub fn interaction_pair(
    &self,
    id1: ColliderGraphIndex,
    id2: ColliderGraphIndex
) -> Option<(N, N, &E)>

The interaction between the two collision objects identified by their graph index.

pub fn interaction_pair_mut(
    &mut self,
    id1: ColliderGraphIndex,
    id2: ColliderGraphIndex
) -> Option<(N, N, &mut E)>

The interaction between the two collision objects identified by their graph index.

pub fn interactions_with(
    &self,
    id: ColliderGraphIndex
) -> impl Iterator<Item = (N, N, &E)>

All the interaction involving the collision object with graph index id.

pub fn index_interaction(
    &self,
    id: TemporaryInteractionIndex
) -> Option<(N, N, &E)>

Gets the interaction with the given index.

pub fn interactions_with_mut(
    &mut self,
    id: ColliderGraphIndex
) -> impl Iterator<Item = (N, N, TemporaryInteractionIndex, &mut E)>

All the mutable references to interactions involving the collision object with graph index id.

Trait Implementations

impl<N: Clone, E: Clone> Clone for InteractionGraph<N, E>

fn clone(&self) -> InteractionGraph<N, E>

Returns a copy of the value.

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

Performs copy-assignment from source.
