I have gameObject MainCamera and there is script LookAtCamera as my main view option and I have script MouseLook that I wanna make secondary with right-click.
using UnityEngine;
using System.Collections;
public class CameraManager : MonoBehaviour {
    void Update () {
        if (Input.GetKey (KeyCode.Mouse1)) {
            LookAtCamera.enabled = false;
            MouseLook.enabled = true;
        }    
    }
}
How to declare script as a public component of MainCamera? I just have one of them enabled and switch between with mouse right click.
                        
Thx :) I didn't know how to declare script. I also added else to go back to default camera setup.
