hey guys,
recently started learning script and i'd quite like something explained please. the script below works great for my character but he turns relative to the world axis rather than the direction he's facing. for instance using WASD i'd like my character to turn to his left when a is pressed and not just walk of in the direction of the z axis regardless of which way he's facing. So if someone could highlight and explain the parts i should be looking at i'd appreciate it very much. got the cam sorted so now it's always behind the character so at least i'm learning something.
