Okay, I've been trying to implement Stevie's DeltaRoll stuff, but I just can't seem to get it to work. I'm not trying to do any momentum stuff here, just simple turning and moving forwards. But when I implement it, the value for DeltaRoll always seems to be 90 or -90, and when I have the ship turn each frame, even a slight amount, based on this DeltaRoll value, the sign for DeltaRoll changes every frame, effectively keeping the ship always facing the same direction, regardless of where its target is.
