PhysicsNamespace: UnityEngine

AllLayers	Layer mask constant to select all layers.
bounceThreshold	Two colliding objects with a relative velocity below this will not bounce (default 2). Must be positive.
DefaultRaycastLayers	Layer mask constant to select default raycast layers.
gravity	The gravity applied to all rigid bodies in the scene.
IgnoreRaycastLayer	Layer mask constant to select ignore raycast layer.
maxAngularVelocity	The default maximum angular velocity permitted for any rigid bodies (default 7). Must be positive.
minPenetrationForPenalty	The minimum contact penetration value in order to apply a penalty force (default 0.05). Must be positive.
sleepAngularVelocity	The default angular velocity, below which objects start sleeping (default 0.14). Must be positive.
sleepVelocity	The default linear velocity, below which objects start going to sleep (default 0.15). Must be positive.
solverIterationCount	The default solver iteration count permitted for any rigid bodies (default 7). Must be positive.

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.
CheckCapsule	Returns true if there are any colliders overlapping the capsule defined by the axis going from start and end and having radius in world coordinates.
CheckSphere	Returns true if there are any colliders overlapping the sphere defined by position and radius in world coordinates.
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.
Linecast	Returns true if there is any collider intersecting the line between start and end.
OverlapSphere	Returns an array with all colliders touching or inside the sphere.
Raycast	Casts a ray against all colliders in the scene.
RaycastAll	Casts a ray through the scene and returns all hits. Note that order is not guaranteed.
SphereCast	Casts a sphere against all colliders in the scene and returns detailed information on what was hit.
SphereCastAll	Like Physics.SphereCast, but this function will return all hits the sphere sweep intersects.
