Question Trying to refactor character controller help

i've been struggling trying to refactor my character controller into a HandleRotation() and HandleMovement() function. i'm using the new input system, _getMovementInput is reading a vector 2 from the input assets. adding a controller.move(moveDir * Time.DeltaTime) into my handleMovement() function works but because "targetAngle" is in the y, i loose my gravity. i have a vector 3 "_moveDirection" that is set to _getMovementInput.x, 0, _getMovementInput.y and if i pass that in i get my gravity back but loose the ability to turn with the camera.

Code (CSharp):

1. private void HandleRotation()
2.     {
3.         Vector3 direction = new Vector3(_getMovementInput.x, 0, _getMovementInput.y);
4.  
5.         if (IsMovementPressed)
6.         {
7.          
8.             targetAngle = (float)(Math.Atan2(direction.x, direction.z) * Mathf.Rad2Deg) + cam.eulerAngles.y;
9.             float angle = Mathf.SmoothDampAngle(transform.eulerAngles.y, targetAngle, ref turnSmoothVelocity, turnSmoothTime);
10.             transform.rotation = Quaternion.Euler(0f, angle, 0f);
11.  
12.             moveDir = Quaternion.Euler(0, targetAngle, 0) * Vector3.forward;
13.          
14.         }
15.     }

Code (CSharp):

1. private void Move_started(InputAction.CallbackContext obj)
2.     {
3.        
4.         _getMovementInput = obj.ReadValue<Vector2>();
5.         _moveDirection.x = _getMovementInput.x;
6.         _moveDirection.z = _getMovementInput.y;
7.         _isMovementPressed = _getMovementInput.x != 0 || _getMovementInput.y != 0;
8.  
9.     }
