I have a button in my scene, a main camera and an empty game object.

Whenever I click on that button my camera should slowly lerp to that empty game object's position.

My camera is lerping to that position, which is fine, but the problem is that I have to click multiple times on that button until my camera reach its position. So is there a way to move my camera to game object's position using a single click on that button?

Here is my code:

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

public class TransitionCAM : MonoBehaviour 
 public Transform views;
 public float transitionSPEED;
 Transform currentVIEW;

 public void move()
 currentVIEW = views;
 transform.position = Vector3.Lerp (transform.position, currentVIEW.position, Time.deltaTime * transitionSPEED);

 //for camera rotation
 Vector3 currentangel = new Vector3 ( Mathf.LerpAngle(transform.rotation.eulerAngles.x, currentVIEW.transform.rotation.eulerAngles.x, Time.deltaTime *transitionSPEED),
 Mathf.LerpAngle(transform.rotation.eulerAngles.y, currentVIEW.transform.rotation.eulerAngles.y, Time.deltaTime *transitionSPEED),
 Mathf.LerpAngle(transform.rotation.eulerAngles.z, currentVIEW.transform.rotation.eulerAngles.z, Time.deltaTime *transitionSPEED));

 transform.eulerAngles = currentangel;
 

Problem is your Vector3.Lerp runs only once. Try this instead:

 public Transform views;
 public float transitionSPEED;
 Transform currentVIEW;
 private bool flag = false;

 Vector3 currentangel;
 private void Start()
 
 Debug.Log(flag);
 currentVIEW = views;

 
 private void Update()
 
 if (flag == true)
 

 transform.position = Vector3.Lerp(transform.position, currentVIEW.position, Time.deltaTime * transitionSPEED);
 Debug.Log("object pos" + transform.position);
 Debug.Log(currentVIEW.position);
 //for camera rotation

 currentangel = new Vector3(Mathf.LerpAngle(transform.rotation.eulerAngles.x, currentVIEW.transform.rotation.eulerAngles.x, Time.deltaTime * transitionSPEED),
 Mathf.LerpAngle(transform.rotation.eulerAngles.y, currentVIEW.transform.rotation.eulerAngles.y, Time.deltaTime * transitionSPEED),
 Mathf.LerpAngle(transform.rotation.eulerAngles.z, currentVIEW.transform.rotation.eulerAngles.z, Time.deltaTime * transitionSPEED));

 transform.eulerAngles = currentangel;
 
 



 public void Move()
 
 flag = true;
 

You have to come up with a way to stop lerping when your camera is at correct position. Because this if (flag == true) will be always true after button is pressed.

This is a better solution i believe using Coroutine

public Transform views;
public float transitionSPEED;
Transform currentVIEW;
private bool flag = false;
private bool isStarted = false;
Vector3 currentangel;
private void Start()

 Debug.Log(flag);
 currentVIEW = views;


private void Update()

 if (flag && !isStarted)
 
 StartCoroutine(CoroutineSolution());
 isStarted = true;
 

IEnumerator CoroutineSolution()

 float t = 0.0f;
 while ( t<1.0f )
 

 t += Time.deltaTime;
 transform.position = Vector3.Lerp(transform.position, currentVIEW.position, t);

 //for camera rotation

 currentangel = new Vector3(Mathf.LerpAngle(transform.rotation.eulerAngles.x, currentVIEW.transform.rotation.eulerAngles.x, t),
 Mathf.LerpAngle(transform.rotation.eulerAngles.y, currentVIEW.transform.rotation.eulerAngles.y, t),
 Mathf.LerpAngle(transform.rotation.eulerAngles.z, currentVIEW.transform.rotation.eulerAngles.z, t));

 transform.eulerAngles = currentangel;
 Debug.Log("Coroutine running");

 yield return null;

 




public void Move()

 flag = true;
