How to constrain an object's motion with the Simple Motion Actuator I've defined a Logic Bricks Simple Motion Actuator which responds to keyboard input to move an object along the Z axis. It works fine, but I want the object to be limited to move from 0.0 to 5.0 along the Z axis. Once it reaches one of those limits I don't want it to move anymore.

I tried adding an Object Constraint, which limits my ability to move it in the editor, but that constraint is not imposed by the game engine.

What do I need to do to impose that constraint on the game engine?
Constraints in game engine are defined using logic bricks or Python.
