[ODE] Pushing an object.

[Vrej Melkonian]

Happy New Year back to you!

I was thinking that you could make the object a body
only object so you can position it as you wish. ODE
won't apply gravity or any forces to it.

The hinge method is possible also. It would be as if
the object is hooked with a tether.
