Description

Global physics properties and helper methods.

Static Properties

AllLayers	Layer mask constant to select all layers.
autoSimulation	Sets whether the physics should be simulated automatically or not.
autoSyncTransforms	Whether or not to automatically sync transform changes with the physics system whenever a Transform component changes.
bounceThreshold	Two colliding objects with a relative velocity below this will not bounce (default 2). Must be positive.
defaultContactOffset	The default contact offset of the newly created colliders.
defaultPhysicsScene	The PhysicsScene automatically created when Unity starts.
DefaultRaycastLayers	Layer mask constant to select default raycast layers.
defaultSolverIterations	The defaultSolverIterations determines how accurately Rigidbody joints and collision contacts are resolved. (default 6). Must be positive.
defaultSolverVelocityIterations	The defaultSolverVelocityIterations affects how accurately the Rigidbody joints and collision contacts are resolved. (default 1). Must be positive.
gravity	The gravity applied to all rigid bodies in the Scene.
IgnoreRaycastLayer	Layer mask constant to select ignore raycast layer.
interCollisionDistance	Sets the minimum separation distance for cloth inter-collision.
interCollisionStiffness	Sets the cloth inter-collision stiffness.
queriesHitBackfaces	Whether physics queries should hit back-face triangles.
queriesHitTriggers	Specifies whether queries (raycasts, spherecasts, overlap tests, etc.) hit Triggers by default.
reuseCollisionCallbacks	Determines whether the garbage collector should reuse only a single instance of a Collision type for all collision callbacks.
sleepThreshold	The mass-normalized energy threshold, below which objects start going to sleep.

Static Methods

BoxCast	Casts the box along a ray and returns detailed information on what was hit.
BoxCastAll	Like Physics.BoxCast, but returns all hits.
BoxCastNonAlloc	Cast the box along the direction, and store hits in the provided buffer.
CapsuleCast	Casts a capsule against all colliders in the Scene and returns detailed information on what was hit.
CapsuleCastAll	Like Physics.CapsuleCast, but this function will return all hits the capsule sweep intersects.
CapsuleCastNonAlloc	Casts a capsule against all colliders in the Scene and returns detailed information on what was hit into the buffer.
CheckBox	Check whether the given box overlaps with other colliders or not.
CheckCapsule	Checks if any colliders overlap a capsule-shaped volume in world space.
CheckSphere	Returns true if there are any colliders overlapping the sphere defined by position and radius in world coordinates.
ClosestPoint	Returns a point on the given collider that is closest to the specified location.
ComputePenetration	Compute the minimal translation required to separate the given colliders apart at specified poses.
GetIgnoreLayerCollision	Are collisions between layer1 and layer2 being ignored?
IgnoreCollision	Makes the collision detection system ignore all collisions between collider1 and collider2.
IgnoreLayerCollision	Makes the collision detection system ignore all collisions between any collider in layer1 and any collider in layer2.Note that IgnoreLayerCollision will reset the trigger state of affected colliders, so you might receive OnTriggerExit and OnTriggerEnter messages in response to calling this.
Linecast	Returns true if there is any collider intersecting the line between start and end.
OverlapBox	Find all colliders touching or inside of the given box.
OverlapBoxNonAlloc	Find all colliders touching or inside of the given box, and store them into the buffer.
OverlapCapsule	Check the given capsule against the physics world and return all overlapping colliders.
OverlapCapsuleNonAlloc	Check the given capsule against the physics world and return all overlapping colliders in the user-provided buffer.
OverlapSphere	Computes and stores colliders touching or inside the sphere.
OverlapSphereNonAlloc	Computes and stores colliders touching or inside the sphere into the provided buffer.
Raycast	Casts a ray, from point origin, in direction direction, of length maxDistance, against all colliders in the Scene.
RaycastAll	Casts a ray through the Scene and returns all hits. Note that order is not guaranteed.
RaycastNonAlloc	Cast a ray through the Scene and store the hits into the buffer.
RebuildBroadphaseRegions	Rebuild the broadphase interest regions as well as set the world boundaries.
Simulate	Simulate physics in the Scene.
SphereCast	Casts a sphere along a ray and returns detailed information on what was hit.
SphereCastAll	Like Physics.SphereCast, but this function will return all hits the sphere sweep intersects.
SphereCastNonAlloc	Cast sphere along the direction and store the results into buffer.
SyncTransforms	Apply Transform changes to the physics engine.
