Ah, I think I might know what’s happening. If you press F6 to run the Player scene by itself, I’m betting this will work, as there doesn’t appear to be anything wrong in this screenshot. That would indicate that the changes aren’t being passed on to the Player instance in your Level scene. This can occasionally happen at the beginning of a project when you’re still in the process of creating your object scenes.
If the Player scene works by itself, just delete the Player instance in the Level scene and replace it. If that doesn’t work, then something more unusual is going on and we’ll go from there.
