There is a bug in my code above. When I toggle from longMvt to shortMvt there seems to be an extra shift happening after pressing the TAB. While shifting from shortMvt to longMvt everything is fine. Can anyone find a solution please? I have omitted the x coordinate code |

| I kinda got it. If I insert FlushKeys the problem goes away for now. I replaced If KeyHit(15) Then ;tab movementType = -movementType End If with If KeyHit(15) Then ;tab movementType = -movementType FlushKeys End If |
