calculate different angles in 2d

Question

Hey There!
i am trying to replicate game Missiles! from the playstore.
My Current code works like this.

     private void Update()
     {
         Vector2 joyinput = new Vector2(joystick.Horizontal, joystick.Vertical);
         rb.MovePosition(transform.position + (movespeed * transform.up));
         float angle = Quaternion.FromToRotation(transform.up, joyinput).eulerAngles.z;
         rb.MoveRotation((transform.rotation.eulerAngles).z + turnspeed * angle);
     
     }

This Image describes my problem the best: alt text Soo how would i convert the current angle (left) to the correct angle (right)?

Thanks for any help!

You could accomplish this with if statements, like

 if (dir == 0 && underneathCenter)
 {
       transform.eulerAngles = Vector3.zero
 }

or something like that

Yeah your right Didnt think of this if (angle > 0 && angle <= 90) {

         }else if(angle > 90 && angle <= 180)
         {
             angle = angle - 180;
         }
         else if (angle > 180 && angle <= 270)
         {
             angle = angle - 180;
         }
         else if (angle > 270 && angle <= 360)
         {
             angle = angle - 360;
         }
