Applies a force to a rigidbody that simulates explosion effects. Other rigidbodies will be affected by the explosion within its radius - the closer they are to the explosionPosition, the stronger the force will be exerted on them.
local obj = Space.Host.ExecutingObject;
obj.Rigidbody.AddExplosionForce (300, obj.WorldPosition, 10, 20)
-- The explosion will occur at the location of the ExecutingObject.
-- Place other rigidbodies around it to observe the effect!
AddForce
Adds a force to the Rigidbody that is continuously exerted on it in the given direction.
local obj = Space.Host.ExecutingObject;
obj.Rigidbody.AddForce (Vector.New(0,100,0));
-- Now the rigidbody is under a continuous force directed upwards (Y direction)
AddForceAtPosition
Adds a force to the Rigidbody at a given position (should be within the range of the rigidbody for a realistic result). Thus, both a torque and force are applied to the object.
local obj = Space.Host.ExecutingObject;
local applyForceHere = Vector.New(obj.WorldPosition.x-0.5,obj.WorldPosition.y-0.5,obj.WorldPosition.z-0.5)
-- This vector is equivalent to one of the lower corners of a 1x1x1 cube.
obj.Rigidbody.AddForceAtPosition (Vector.New(0,40,0), applyForceHere);
-- The object is experiencing an effect similar to being tipped upwards at the aforementioned corner.
AddRelativeTorque
Adds a torque to the rigidbody relative to the local coordinate system.
local obj = Space.Host.ExecutingObject;
Space.Log(obj.Rigidbody.ClosestPointOnBounds (Vector.Zero));
-- prints [x,y,z] to the console, where x,y,z are coordinates of the rigidbody's point that is the closest to the global origin
local obj = Space.Host.ExecutingObject;
local moveHere = Vector.New(obj.WorldPosition.x+10,obj.WorldPosition.y,obj.WorldPosition.z);
obj.Rigidbody.MovePosition (moveHere);
-- The object has been moved by 10 units in the positive X direction
local obj = Space.Host.ExecutingObject;
local setRotationTo = Quaternion.Euler(60,0,0)
obj.Rigidbody.MoveRotation (setRotationTo);
-- The object's rotation has been set to 60 degrees in the positive X direction and 0 in Y and Z
local obj = Space.Host.ExecutingObject;
obj.Rigidbody.CenterOfMass = Vector.New(1,1,1);
Space.Log(obj.Rigidbody.CenterOfMass);
-- prints "[1,1,1]" to the console
obj.Rigidbody.ResetCenterOfMass();
Space.Log(obj.Rigidbody.CenterOfMass);
-- prints "[0,0,0]" to the console

hits = rigid.SweepTestAll(solid.Forward , 20)
--sweep forward 20 meters, and return all hits.

local obj = Space.Host.ExecutingObject;
-- Set a new angular velocity vector
obj.Rigidbody.AngularVelocity = Vector.New(0,Space.Math.Pi,0);

The maximum depenetration velocity of the rigidbody (1.00000003318135E+32 by default). Can be useful to make colliding objects bounce away in a smoother fashion.
local obj = Space.Host.ExecutingObject;
-- Set UseGravity to False (it is set to True by default)
obj.Rigidbody.UseGravity = false;
-- Now gravity does not affect the rigidbody.
-- Get the UseGravity value (find out if UseGravity is in action)

local obj = Space.Host.ExecutingObject;
-- Get the current center of mass
Space.Log(obj.Rigidbody.WorldCenterOfMass);
-- prints "[x, y, z]" to the console, where x,y,z are global coordinates of the center of mass. If CenterOfMass == [0,0,0], then x,y,z are equal to the global coordinates of the object.

Space.Log(obj.Rigidbody.Sleeping);
-- prints "True" to the console

Space.Log(obj.Rigidbody.Sleeping);

Density
float Densityset
The density of the object (1 by default). Changing this value will affect the mass of the object (the volume will remain unchanged).
density = Space.Host.ExecutingObject.Rigidbody.Density
local obj = Space.Host.ExecutingObject;
Space.Log(obj.Rigidbody.Mass);
-- prints "1" to the console
obj.LocalScale = Vector.New(2,2,2);
obj.Rigidbody.Density = 0.5;
Space.Log(obj.Rigidbody.Mass);
-- prints "4" to the console - the density is 2 times lower, and the object is 8 times bigger, therefore it's 4 times heavier.
The diagonal inertia tensor of mass relative to the center of mass. It is defined in x,y,z axis. It is calculate by physics automatically,and if you set value to it, it would override the value.
