Question by gemmaF · May 08, 2018 at 07:25 PM · zoom

Set zoom limits to camera

Hello!

I'm working on a very simple script to make my camera zoom in and out of my object but at the moment the zoom has no limits and if I zoom in too much my object turns upside down. Can someone point out a possible way to fix this? I red other posts about this matter but my scripting skills are very very basic and it seems I can't find something working with what I have at the moment. Here the script.

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

public class ZoomCam : MonoBehaviour {

 //public float speed;

 // Use this for initialization
 void Start () {
     
 }
 
 // Update is called once per frame
 void Update () {
    
     if(Input.GetAxis("Mouse ScrollWheel") > 0)
     {

         GetComponent<Camera>().fieldOfView--;
     }

     if (Input.GetAxis("Mouse ScrollWheel") < 0)
     {

         GetComponent<Camera>().fieldOfView++;
     }
 }

}

Look at mathf.clamp. This will clamp the max and minimum positions of the field of view. Also, for camera movements its best to put it in LateUpdate function rather than Update function.
