Lookrotation for TwinStick Shooter

Hello,

iam trying to use two Axis for a twin stick shooter (2D).

Axis 1 (WASD) shall move the Character (with Rigidbody)

Axis 2 (IJKL) shall rotate the Character smooth in Shooting Direction Like pressing I and L let the character look top-Right and so on...

Even checking out google, i dont find a good solution to make the rotation smooth.

Hope you can help ;)

Thanks !

My Code so far:

void Start() { rb = GetComponent(); animator = GetComponent(); }

 // Update is called once per frame
 void Update()
 {
     move.x = Input.GetAxisRaw("HorizontalMove");
     move.y = Input.GetAxisRaw("VerticalMove");

     actionDir.x = Input.GetAxisRaw("HorizontalAction");
     actionDir.y = Input.GetAxisRaw("VerticalAction");

 }

 private void FixedUpdate()
 {
     rb.MovePosition(rb.position + move * moveSpeed * Time.deltaTime);
 }
