SetItem(Libraries.Interface.Item2D item)

This action attaches a 2D item, which includes the shape, friction, restitution, positions, and others of a 2D object as a part of the properties that this 2D item has.

Parameters

SetRestitution(number restitution)

This action sets how much energy that this 3D object will loose after a collision. If you want the object to not loose any energy, then you can pass in 1.0.
