I ran into an issue where I had my code more or less set up like the code in the lecture (different names for things, but the same logic), but my tank refused to turn. I saw some other posts about friction being a potential cause, and I think that is a solid theory.
To get my tank to turn, in the method where the throttles are set to turn the tank, I multiplied the Throw value by 2. This allowed my tank to turn better without setting the overall force to make my tank shoot off into the edges of my map when going straight.
I realize once the incoming values to throttle are clamped this will not be a viable solution. but I am hoping by that time a better way to handle movement and turning in general will come up (either in the course or just raw ideas).
