SetMoveObjects works with Hands too..? or not..

[Mudbill]

MoveObjects do not need mass to move, but they will only move by script. If you have both mass and a script to move it upwards, it likely won't work as it will fall back down.

Anyhow, yes you will need a new entity. What you've seen probably consists of new entities using existing models (it's very common). Just import the mesh in the Model Editor, then make it into a MoveObject.

Doing the same with the key should work too, but if the MoveObject has a collision box, it might also push the normal dynamic key with it as it moves.
