Thanks for the reply Martin, I’m really just trying to understand why ‘calling’ these functions (thanks for the carification) before the player moves stops the spin bug, but calling them after playerTurn or the movement sequence doesn’t seem to have any effect at all.
Logically, it seems to me, that you should tell the player to turn and then add these functions to stop him turning too far. But obviously that’s not the way it’s done.
Ah well, no matter, the lovely thing works and that’s all that’s important 
.
Cheers
