Struct RapierContextColliders 

pub struct RapierContextColliders {
    pub colliders: ColliderSet,
    /* private fields */
}

The set of colliders part of the simulation.

This should be attached on an entity with a RapierContextSimulation

With the serde-serialize feature, the entity-to-handle map isn’t serialized: it is rebuilt from the colliders’ user-data on deserialization (see Self::rebuild_entity_maps).

Fields

colliders: ColliderSet

The set of colliders part of the simulation.

Implementations

impl RapierContextColliders

pub fn rebuild_entity_maps(&mut self)

Rebuilds the map from entities to collider handles from the user-data of the colliders, which contain the bits of their entity.

This is called automatically when deserializing this component. Call it manually after replacing Self::colliders with a set restored in another way.

pub fn collider_parent( &self, rigidbody_set: &RapierRigidBodySet, entity: Entity, ) -> Option<Entity>

If the collider attached to entity is attached to a rigid-body, this returns the Entity containing that rigid-body.

pub fn rigid_body_colliders<'a, 'b: 'a>( &'a self, entity: Entity, rigidbody_set: &'b RapierRigidBodySet, ) -> impl Iterator<Item = Entity> + 'a

If entity is a rigid-body, this returns the collider Entitys attached to that rigid-body.

pub fn collider_entity(&self, handle: ColliderHandle) -> Option<Entity>

Retrieve the Bevy entity the given Rapier collider (identified by its handle) is attached to.

pub fn entity_from_collider(collider: &Collider) -> Entity

Retrieve the Bevy entity the given Rapier collider is attached to.

pub fn entity2collider(&self) -> &HashMap<Entity, ColliderHandle>

The map from entities to collider handles.

pub fn compute_aabb(&self, entity: Entity) -> Option<Aabb3d>

Computes the world-space axis-aligned bounding box of the collider of entity.

This doesn’t include the contact skin. Returns None if entity has no collider.

pub fn compute_swept_aabb( &self, entity: Entity, next_position: Transform, ) -> Option<Aabb3d>

Computes the world-space axis-aligned bounding box swept by the collider of entity when moving from its current position to next_position.

The scale of next_position is ignored. Returns None if entity has no collider.

pub fn volume(&self, entity: Entity) -> Option<f32>

The volume (in 3D) or area (in 2D) of the collider of entity.

Returns None if entity has no collider.

pub fn mass(&self, entity: Entity) -> Option<f32>

The mass of the collider of entity.

Returns None if entity has no collider.

pub fn density(&self, entity: Entity) -> Option<f32>

The density of the collider of entity.

If the collider’s mass was set explicitly, this is the mass divided by the volume. Returns None if entity has no collider.

Trait Implementations

impl Clone for RapierContextColliders

fn clone(&self) -> RapierContextColliders

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Component for RapierContextColliders

where Self: Send + Sync + 'static,

const STORAGE_TYPE: StorageType = ::bevy::ecs::component::StorageType::Table

A constant indicating the storage type used for this component.

type Mutability = Mutable

A marker type to assist Bevy with determining if this component is mutable, or immutable. Mutable components will have Component<Mutability = Mutable>, while immutable components will instead have Component<Mutability = Immutable>.

fn register_required_components( _requiree: ComponentId, required_components: &mut RequiredComponentsRegistrator<'_, '_>, )

Registers required components.

fn clone_behavior() -> ComponentCloneBehavior

Called when registering this component, allowing to override clone function (or disable cloning altogether) for this component.

fn relationship_accessor() -> Option<ComponentRelationshipAccessor<Self>>

Returns ComponentRelationshipAccessor required for working with relationships in dynamic contexts.

fn on_add() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_add ComponentHook for this Component if one is defined.

fn on_insert() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_insert ComponentHook for this Component if one is defined.

fn on_discard() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_discard ComponentHook for this Component if one is defined.

fn on_remove() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_remove ComponentHook for this Component if one is defined.

fn on_despawn() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_despawn ComponentHook for this Component if one is defined.

fn map_entities<E>(_this: &mut Self, _mapper: &mut E)

where E: EntityMapper,

Maps the entities on this component using the given EntityMapper. This is used to remap entities in contexts like scenes and entity cloning. When deriving Component, this is populated by annotating fields containing entities with #[entities]

const HAS_SUMMARY_TICK: bool = false

Set this constant to true if the component should track a summary tick.

impl Debug for RapierContextColliders

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

Formats the value using the given formatter.

impl Default for RapierContextColliders

fn default() -> RapierContextColliders

Returns the “default value” for a type.
