Camera field of view issues with lerp, DoTween, iTween etc.

Hi all,

I’m having an issue with smoothly moving the camera field of view in my game that I cannot resolve.

I have a script attached to the camera that follows the player, this checks if the player is within a certain distance to an object, if it is then the field of view zooms in, if it is not within a certain distance then the field of view zooms out.

In my code I have a list of objects and I iterate over each one to check the distance. The code does work, but the more objects I add to the list the less the field of view zooms in or out. I tried math.lerp, DoTween and iTween and I get the same issue with all of them so the issue is with how I’ve coded it.

Thanks in advance!

Here’s my cameraFollow script:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using DG.Tweening;

public class CameraFollow : MonoBehaviour

    public GameObject player;

    private GameObject launchPad;
    private GameObject tnt;
    private Camera cam;

    public float cameraHeight = 20f;
    public float offsetX = 0;
    public Vector3 pos;

    private float targetFOV = 25.0f;
    private float defaultFOV = 40.0f;
    //public float speed = 0.2f;
    public float distanceToBject = 10.0f;
    [SerializeField] float cameraZoomSpeed = 0.5f;

    List<GameObject> fovGroup = new List<GameObject>();

    // Use this for initialization
    void Start()

        launchPad = GameObject.Find("Launchpad2");
        tnt = GameObject.Find("tnt_low");
        DOTween.SetTweensCapacity(2000, 50);
        cam = Camera.main;



    // Update is called once per frame
    void LateUpdate()
        pos = player.transform.position;
        pos.x += offsetX;
        pos.z += cameraHeight;
        transform.position = pos;



    private void ZoomFOV()
        foreach (GameObject pickup in fovGroup)
            if (pickup == null)
            if (Vector3.Distance(pickup.transform.position, player.transform.position) <= distanceToBject)

    private void ZoomCameraIn()
        cam.DOFieldOfView(targetFOV, cameraZoomSpeed).SetEase(Ease.OutSine);

    private void ZoomCameraOut()
        cam.DOFieldOfView(defaultFOV, cameraZoomSpeed).SetEase(Ease.OutSine);


got it sorted, didn’t realise that the logic in the code was fighting with itself, School boy error!
