I'm attempting to make a character face the joystick in a top down unity2d game.

I already have a working script that rotates the player towards the mouse, but I have no idea how to change that so that it rotates to the joystick. I'm looking to create a script for a second player. Here is the code making the character look at the mouse

 mousePos = cam.ScreenToWorldPoint(new Vector3(Input.joystickPosition.x, Input.mousePosition.y, Input.mousePosition.z - cam.transform.position.z));
         rid.transform.eulerAngles = new Vector3(0, 0, Mathf.Atan2((mousePos.y - transform.position.y), (mousePos.x - transform.position.x)) * Mathf.Rad2Deg);

Sorry for bad English. Any help will be greatly appreciated
