Struct jumpy::core::physics::collisions::CollisionCache
source · pub struct CollisionCache {
pub collisions: Arc<AtomicCell<IndexMap<Entity, Vec<Entity>, BuildHasherDefault<EntityHasher>>>>,
removed_colliders: IndexMap<ColliderHandle, Entity>,
}
Expand description
A cache containing a map of entities, to the list of entities that each entity is currently intersecting with.
Fields§
§collisions: Arc<AtomicCell<IndexMap<Entity, Vec<Entity>, BuildHasherDefault<EntityHasher>>>>
The collisions in the cache.
removed_colliders: IndexMap<ColliderHandle, Entity>
Map removed collider handles to entities. When Rapier gives collision event for removal,
the collider is no longer in rapier::ColliderSet
, thus we cannot retrieve our user data
and determine entity to be removed.
Colliders should be added here on removal for event processing, this is cleared each frame.
TODO: Consider a safer way to handle this that doesn’t involve remembering to update this on removal.
Implementations§
source§impl CollisionCache
impl CollisionCache
sourcepub fn get(&self, entity: Entity) -> RefMut<'_, Vec<Entity>>
pub fn get(&self, entity: Entity) -> RefMut<'_, Vec<Entity>>
Get the set of entities that the given entity
is intersecting.
sourcepub fn collider_removed(
&mut self,
entity: Entity,
collider_handle: ColliderHandle,
)
pub fn collider_removed( &mut self, entity: Entity, collider_handle: ColliderHandle, )
Notify cache of removal of collider to correctly handle stop event on removed collider.
see Self::removed_colliders_userdata
field comment for details.
sourcepub fn clear_removed_colliders(&mut self)
pub fn clear_removed_colliders(&mut self)
Clear tracked data for removed colliders this frame (call after rapier update)
