I'm trying to zoom in on an object once the raycast hits it in the Update method, I am using the Lerp method to make the camera movement smoother but it's not working properly.

Here's a sample of my code :

if (Input.GetMouseButtonDown(0))
        {
            ray = mainCam.ScreenPointToRay(Input.mousePosition);
            if (Physics.Raycast(ray, out hit))
            {

                if (hit.collider.tag.Equals("Building")) 
                {
                    
                    SetTarget(hit);
                    mainCam.fieldOfView = Mathf.Lerp(mainCam.fieldOfView, newFOV, Time.deltaTime * smooth);
                }
            }
         }

I'm trying to zoom in on an object once the raycast hits it in the Update method, I am using the Lerp method to make the camera movement smoother but it's not working properly. The object only lerps for a single frame.

I also tried using a coroutine but the result is still the same. I can't simply just place it outside the if statement because I only need to change the field of view once the raycast hits an object.

Here's a sample of my code :

if (Input.GetMouseButtonDown(0))
        {
            ray = mainCam.ScreenPointToRay(Input.mousePosition);
            if (Physics.Raycast(ray, out hit))
            {

                if (hit.collider.tag.Equals("Building")) 
                {
                    
                    SetTarget(hit);
                    mainCam.fieldOfView = Mathf.Lerp(mainCam.fieldOfView, newFOV, Time.deltaTime * smooth);
                }
            }
         }
