I have been trying make a c# script that can change the cardboard camera to other cardboard camera, like when a character choose a chair, he teleport to cardboard camera on this chair:
Basically I just want switch cardboard camera for another cardboard camera.

This is c# script that I use:

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

public class teste1 : MonoBehaviour {
    
    public GameObject[] CamInicial = new GameObject[59]; // inicialização da camera
    public GameObject[] CamNext = new GameObject[59]; // camera para a qual se vai fazer switch
    int n; // id da camera

    // Use this for initialization
    void Start()
    {

    }

    // Update is called once per frame
    void Update()
    {
        if (Physics.Raycast(transform.position, transform.forward, out hit))
        {
            if (CamNext[n] != null)
            {
                switchCameras(n);
            }
        }
    }
       

    private void switchCameras(int keyNum)
    {
        for (int i = 0; i < CamNext.Length + 1; i++)
        {
            if (CamNext *!= null && keyNum != i)*

{
// turn camera off
CamNext*.GetComponent().enabled = false;*
}
else {
// turn camera on
CamNext*.GetComponent().enabled = true;*
}
}
}
}
Console error:
Assets/Scripts/teste1.cs(22,72): error CS0103: The name `hit’ does not exist in the current context

You need this line before your Raycast:

RaycastHit hit;

If you want to use the out hit version of Physics.Raycast.

However, it looks like you aren’t using hit anyway, so you should omit the out hit parameter from your call to Physics.Raycast
