Impulse created by the contact. Only implemented for Bullet physics. The angular velocity of the body. The inverse of the inertia of the body. The inverse of the mass of the body. The linear velocity of the body. [code]true[/code] if this body is currently sleeping (not active). The timestep (delta) used for the simulation. The rate at which the body stops rotating, if there are not any other forces moving it. The total gravity vector being currently applied to this body. The rate at which the body stops moving, if there are not any other forces moving it. The transformation matrix of the body.
