Yea, I’ll look at the code, but I’m getting that couch error too. When you press it, you just go “fly” into the air as you hold the key down. I’m using a windows OS, so that may have to do with the problem maybe? Again, I’ll see what I can do.
Edit. Ok Not 100% sure, but you put 1.2 for self.crouchLevitation, so I changed it to .2 and then it seem to go down as normal, but when you hold on to it to long you’ll go thow the floor or the wall. This means it’s not locking after you press the key. I mean, it’s still going in the loops to go down. Maybe its gravity + couch, it says I hit the floor with a -5.
