Rotate a character with joystick

Hi, i have a question.

I make Joystick.

The Target is Character.

Well... The moving is well.

But, rotate is not good.

When i use touched position like this :

if (Input.GetMouseButtonDown(0)) { if (Physics.Raycast(Camera.main.ScreenPointToRay(Input.mousePosition), out hit)) { touchedPos = hit.point; dir = Quaternion.LookRotation( (touchedPos - transform.position).normalized); dir.x = 0; dir.z = 0; } } transform.rotation = Quaternion.Slerp(transform.rotation, dir, turnSpeed * Time.deltaTime); }

This code is nice moving.

But, now I doesn't use Input.GetMouseButtonDown.

Only use Joystick for device. like this :

Vector3 touchPos = UICamera.currentCamera.ScreenToWorldPoint(new Vector3(Input.mousePosition.x, Input.mousePosition.y, 0));

         Vector3 dir = (touchPos - oriPosition).normalized;
         float length = Vector3.Distance(oriPosition, touchPos);

         if (length > stickRadius)
             transform.position = oriPosition + (dir * stickRadius);
         else
             transform.position = touchPos;

         /// direction 
         Target.MoveCharacter( new Vector3(dir.x, 0, dir.y) );
                     /// ratate
         Target.GetComponent<Turn>().SetRotation( ???? );

Q : How to ratate a character with joystick in 3d Model ? // The rotate axis is Y.
