Hello, there appears to be this bug with location constraint where an object hitting the location limit jerks a little. Can you test the file please and tell me if you get the same thing? Here’s how to see the bug:
- start game engine,
- press leftarrow or rightarrow to move the box.
- If you hold rightarrow to get all the way to the constraint limit and then release the key, the cube moves back a little. The leftarrow works fine, the cube stops at the constraint limit and stays there.
Here’s the blend:
