float HorizontalVaule = input.Getaxis(“horizontal”) * WalkingSpeed;
Vector3 fowardDirection = VerticalValue * Transform.Foward;
Vector3 SideDirection = HorizontalVaule * Transform.right;
Vector3 totalDirection = fowardDirection + SideDirection;
CharacterContrller.SimpleMove(totalDirection);
float rotatevalue = input.Getaxis(“mouse X”) * TurnSpeed;

Use code tags , explain what you want to have happen, explain what actually happened instead. If you got an error message, paste the exact message, and clearly indicate which line it occurred on (if applicable).
