Module collider

Components, traits, and plugins related to collider functionality.

Modules

collider_hierarchy

ColliderOf relationships for attaching colliders to rigid bodies based on the entity hierarchy.

collider_transform

Transform management and types for colliders.

contact_query

Geometric queries for computing information about contacts between two Colliders.

Structs

AabbContext

Context necessary to calculate ColliderAabbs for an AnyCollider

Collider

A collider used for detecting collisions and generating contacts.

ColliderAabb

The Axis-Aligned Bounding Box of a collider in world space.

ColliderBackendPlugin

A plugin for handling generic collider backend logic.

ColliderConstructorHierarchy

A component that will automatically generate Colliders on its descendants at runtime. The type of the generated collider can be specified using ColliderConstructor. This supports computing the shape dynamically from the mesh, in which case only the descendants with a Mesh will have colliders generated.

ColliderConstructorHierarchyConfig

Configuration for a specific collider generated from a scene using ColliderConstructorHierarchy.

ColliderConstructorHierarchyReady

Triggered when a ColliderConstructorHierarchy finished inserting all its Colliders.

ColliderConstructorReady

Triggered when a ColliderConstructor successfully inserted a Collider.

ColliderDisabled

A marker component that indicates that a collider is disabled and should not detect collisions or be included in spatial queries.

ColliderMarker

A marker component for colliders. Inserted and removed automatically.

CollidingEntities

A component for reading which entities are colliding with a collider entity. Must be added manually for desired colliders.

CollisionLayers

Defines the collision layers of a collider using memberships and filters.

CollisionMargin

A component that adds an extra margin or “skin” around Collider shapes to help maintain additional separation to other objects. This added thickness can help improve stability and performance in some cases, especially for thin shapes such as trimeshes.

ContactManifoldContext

Context necessary to calculate ContactManifolds for a set of AnyCollider

LayerMask

A bitmask for layers.

Sensor

A component that marks a Collider as a sensor, also known as a trigger.

TrimeshFlags

Flags used for the preprocessing of a triangle mesh collider.

VhacdParameters

Parameters controlling the VHACD convex decomposition.

Enums

ColliderConstructor

A component that will automatically generate a Collider at runtime using Collider::try_from_constructor. Enabling the collider-from-mesh feature activates support for computing the shape dynamically from the mesh attached to the same entity.

FillMode

Controls how the voxelization determines which voxel needs to be considered empty, and which ones will be considered full.

Traits

AnyCollider

A trait that generalizes over colliders. Implementing this trait allows colliders to be used with the physics engine.

IntoCollider

A trait for creating colliders from other types.

PhysicsLayer

A layer used for determining which entities should interact with each other. Physics layers are used heavily by CollisionLayers.

ScalableCollider

A trait for colliders that support scaling.

SimpleCollider

A simplified wrapper around AnyCollider that doesn’t require passing in the context for implementations that don’t need context

Type Aliases

TrimeshBuilderError

An error indicating an inconsistency when building a triangle mesh collider.
