OK, Hinge seem to be useful, thanks! What exactly I want is to
have two wheel (wheels of a car) and join them with a Hinge but
a Hinge is a rigid thing so they are not free to roll...
Hinge should work for that
+ System: Start of layout
-> Sprite2: Create hinge about (Sprite2.X, Sprite2.Y) with stiffness 90
Something along those lines should create a wheel like object.
