Properties

Name	Description
`Physics`.`autoSyncTransforms`	Whether or not to automatically sync transform changes with the physics system whenever a Transform component changes.
`Physics`.`defaultSolverIterations`	The defaultSolverIterations determines how accurately Rigidbody joints and collision contacts are resolved. (default 6). Must be positive.

Static Properties

Name	Description
`Physics`.`AllLayers`	Layer mask constant to select all layers. (Read-only)
`Physics`.`autoSimulation`	Sets whether the physics should be simulated automatically or not.
`Physics`.`bounceThreshold`	Two colliding objects with a relative velocity below this will not bounce (default 2). Must be positive.
`Physics`.`clothGravity`	Cloth Gravity setting. Set gravity for all cloth components.
`Physics`.`defaultContactOffset`	The default contact offset of the newly created colliders.
`Physics`.`defaultMaxAngularSpeed`	Default maximum angular speed of the dynamic Rigidbody, in radians (default 50).
`Physics`.`DefaultRaycastLayers`	Layer mask constant to select default raycast layers. (constant)
`Physics`.`defaultSolverVelocityIterations`	The defaultSolverVelocityIterations affects how accurately the Rigidbody joints and collision contacts are resolved. (default 1). Must be positive.
`Physics`.`gravity`	The gravity applied to all rigid bodies in the Scene.
`Physics`.`IgnoreRaycastLayer`	Layer mask constant to select ignore raycast layer. (constant)
`Physics`.`interCollisionDistance`	Sets the minimum separation distance for cloth inter-collision. Cloth particles closer than this distance that belong to different Cloth objects will be separated.
`Physics`.`interCollisionStiffness`	Sets the cloth inter-collision stiffness.
`Physics`.`queriesHitBackfaces`	Whether physics queries should hit back-face triangles.
`Physics`.`queriesHitTriggers`	Specifies whether queries (raycasts, spherecasts, overlap tests, etc.) hit Triggers by default. This can be overridden on a per-query level by specifying the QueryTriggerInteraction parameter.
`Physics`.`reuseCollisionCallbacks`	Determines whether the garbage collector should reuse only a single instance of a Collision type for all collision callbacks.
`Physics`.`sleepThreshold`	The mass-normalized energy threshold, below which objects start going to sleep.

Static Methods

Name	Description
`Physics`.`BakeMesh(meshID, convex)`	Prepares the Mesh for use with a MeshCollider.
`Physics`.`BoxCast(physicBox)`	Casts the box along a ray and returns detailed information on what was hit.
`Physics`.`BoxCastAll(physicBox)`	Like Physics.BoxCast, but returns all hits.
`Physics`.`CapsuleCast(physicCapsule)`	Casts a capsule against all colliders in the Scene and returns detailed information on what was hit.
`Physics`.`CapsuleCastAll(physicCapsule)`	Like Physics.CapsuleCast, but this function will return all hits the capsule sweep intersects.
`Physics`.`CheckBox(physicBox)`	Check whether the given box overlaps with other colliders or not.
`Physics`.`CheckCapsule(physicCapsule)`	Checks if any colliders overlap a capsule-shaped volume in world space.
`Physics`.`CheckSphere(physicSphere)`	Returns true if there are any colliders overlapping the sphere defined by PhysicSphere.
`Physics`.`ClosestPoint(point, collider, position, rotation)`	Returns a point on the given collider that is closest to the specified location.
`Physics`.`ComputePenetration(colliderA, positionA, rotationA, colliderB, positionB, rotationB)`	Compute the minimal translation required to separate the given colliders apart at specified poses.
`Physics`.`GetIgnoreCollision(collider1, collider2)`	Checks whether the collision detection system will ignore all collisions/triggers between collider1 and collider2 or not.
`Physics`.`GetIgnoreLayerCollision(layer1, layer2)`	Are collisions between layer1 and layer2 being ignored?
`Physics`.`IgnoreCollision(collider1, collider2, ignore=true)`	Makes the collision detection system ignore all collisions between collider1 and collider2.
`Physics`.`Linecast(physicLine)`	Returns true if there is any collider intersecting the line between start and end.
`Physics`.`OverlapBox(physicBox)`	Find all colliders touching or inside of the given physic box.
`Physics`.`OverlapCapsule(physicCapsule)`	Check the given capsule against the physics world and return all overlapping colliders.
`Physics`.`OverlapSphere(physicSphere)`	Computes and stores colliders touching or inside the sphere.
`Physics`.`Raycast(physicRay)`	Casts a ray, from point origin, in direction direction, of length maxDistance, against all colliders in the Scene.
`Physics`.`RaycastAll(physicRay)`	Casts a ray through the Scene and returns all hits. Note that order of the results is undefined.
`Physics`.`RebuildBroadphaseRegions(worldBounds, subdivisions)`	Rebuild the broadphase interest regions as well as set the world boundaries.
`Physics`.`Simulate(step)`	Simulate physics in the Scene.
`Physics`.`SphereCast(physicSphere)`	Casts a sphere along a ray and returns detailed information on what was hit.
`Physics`.`SphereCastAll(physicSphere)`	Like Physics.SphereCast, but this function will return all hits the sphere sweep intersects.
`Physics`.`SyncTransforms()`	Apply Transform changes to the physics engine.
