In my game you are controlling a person walking(X and Y) and they can:
Rotate view - -180 to +180 Move a direction - Forward, Backwards, Left, Right.
I want the Move to get closer to a goal position by using the Forward, Backward, Left and Right. http://i.stack.imgur.com/OcDr1.png
The player can be looking anywhere on the -180 to 180 rotation and the direction of the Forward, Backward, Left and Right is changed by Rotation.
