Implementations

impl<N: RealField + Copy, T> CollisionWorld<N, T>

pub fn new(margin: N) -> CollisionWorld<N, T>

Creates a new collision world.

pub fn add(
    &mut self,
    position: Isometry<N>,
    shape: ShapeHandle<N>,
    collision_groups: CollisionGroups,
    query_type: GeometricQueryType<N>,
    data: T
) -> (CollisionObjectSlabHandle, &mut CollisionObject<N, T>)

Adds a collision object to the world.

pub fn update(&mut self)

Updates the collision world.

This executes the whole collision detection pipeline:

1. Clears the event pools.
2. Executes the broad phase first.
3. Executes the narrow phase.

pub fn clear_events(&mut self)

Empty the contact and proximity event pools.

pub fn remove(&mut self, handles: &[CollisionObjectSlabHandle])

Removed the specified set of collision objects from the world.

Panics of any handle is invalid, or if the list contains duplicates.

pub fn set_position(
    &mut self,
    handle: CollisionObjectSlabHandle,
    pos: Isometry<N>
)

👎 Deprecated:

Call directly the method .set_position on the collision object.

Sets the position of the collision object attached to the specified object.

pub fn set_query_type(
    &mut self,
    handle: CollisionObjectSlabHandle,
    query_type: GeometricQueryType<N>
)

👎 Deprecated:

Call directly the method .set_query_type on the collision object.

Sets the GeometricQueryType of the collision object.

pub fn set_shape(
    &mut self,
    handle: CollisionObjectSlabHandle,
    shape: ShapeHandle<N>
)

👎 Deprecated:

Call directly the method .set_shape on the collision object.

Sets the shape of the given collision object.

pub fn set_deformations(
    &mut self,
    handle: CollisionObjectSlabHandle,
    coords: &[N]
)

👎 Deprecated:

Call directly the method .set_deformations on the collision object.

Apply the given deformations to the specified object.

pub fn set_broad_phase_pair_filter<F>(&mut self, filter: Option<F>) where
    F: BroadPhasePairFilter<N, CollisionObjectSlab<N, T>> + 'static, 

Sets the user-defined filter that tells if a potential collision pair should be ignored or not.

The proximity filter returns false for a given pair of collision objects if they should be ignored by the narrow phase. Keep in mind that modifying the proximity filter will have a non-trivial overhead during the next update as it will force re-detection of all collision pairs.

Executes the narrow phase of the collision detection pipeline.
