Struct oxygengine_physics_2d::prelude::ncollide2d::pipeline::InteractionGraph

pub struct InteractionGraph<N, Handle>(/* private fields */)
where
    N: RealField + Copy,
    Handle: CollisionObjectHandle;

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

Implementations

impl<N, Handle> InteractionGraph<N, Handle>where N: RealField + Copy, Handle: CollisionObjectHandle,

pub fn new() -> InteractionGraph<N, Handle>

Creates a new empty collection of collision objects.

pub fn add_node(&mut self, handle: Handle) -> NodeIndex<usize>

Adds a handle to this graph.

pub fn remove_node(&mut self, id: NodeIndex<usize>) -> Option<Handle>

Removes a handle from this graph and returns a handle that must have its graph index changed to id.

When a node is removed, another node of the graph takes it place. This means that the CollisionObjectGraphIndex of the collision object returned by this method will be equal to id. Thus if you maintain a map between CollisionObjectSlabHandle and CollisionObjectGraphIndex, then you should update this map to associate id to the handle returned by this method. For example:

// Let `id` be the graph index of the collision object we want to remove.
if let Some(other_handle) = graph.remove_node(id) {
   // The graph index of `other_handle` changed to `id` due to the removal.
   map.insert(other_handle, id) ;
}
