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.
