rotate an object by 180° on click only once

Question

Heyo, so I need to make it so that a 3d-object rotates only once after mouse click. The code I have works, but the object rotates every time I click on it and I need it to do it only once. Code:

using System.Collections; using System.Collections.Generic; using UnityEngine;

public class RotateOnce : MonoBehaviour { public float smooth = 1f; private Vector3 targetAngles;

  void Update () 
  {
      if(Input.GetKeyDown(KeyCode.Mouse0)) 
      targetAngles = transform.eulerAngles + 180f * Vector3.up; 

      transform.eulerAngles = Vector3.Lerp(transform.eulerAngles, targetAngles, smooth * Time.deltaTime); 
  }

}

You can use a bool here

 private bool alreadyRotated = false;

     void Update()
     {
         if (Input.GetKeyDown(KeyCode.Mouse0))
         {
             if (alreadyRotated == false)
             {
                 targetAngles = transform.eulerAngles + 180f * Vector3.up;
                 transform.eulerAngles = Vector3.Lerp(transform.eulerAngles, targetAngles, smooth * Time.deltaTime);
                 alreadyRotated = true;
             }
         } 
     }

doesn't seem to work, but your reasoning is solid. The object with your code keeps rotating every time I click on the screen

rotate an object by 180° on click only once
