Double click detection

To make this work, you need to introduce a timer of some sort don't do the single click until the double click detection has passed. Here is an exmaple:

 using System.Collections;
 using UnityEngine;
 
 public class Example : MonoBehaviour {
 
     public float clickDelta = 0.35f;  // Max between two click to be considered a double click
 
     private bool click = false;
     private float clickTime;
 
     void Update() {
         if (click && Time.time > (clickTime + clickDelta)) {
             transform.Rotate(new Vector3(0, 180, 0));  // Single click
             click = false;
         }
     }
 
     void OnMouseDown() {
         if (click && Time.time <= (clickTime + clickDelta)) {
             transform.Rotate (new Vector3(180,0,0)); // Double click
             click = false;
         }
         else {
             click = true;
             clickTime = Time.time;
         }
     }
 }

I was looking for double click script. I got it , but i have another problem.

I am working on puzzle game. I have 2 gameobjects. first is the sample and i cant move it , second gameobject i need to move to the first as close as possible. When it is close Vector3.Lerp starts working. Everything works but....

at the begining both gameobjects have transform.rotation.z = 0 . And Vector3.Lerp works only if transform.rotation.z = 0. Everytime i double click my transform.rotation.z +=90. When i am doing double click couple times , and transform.rotation.z is again 0 , vector3.lerp doesn't work. Does anybody knows why is it so and how can i fix it ?
