Script sobre manejo de varias camaras

Para cambiar entre dos cámaras:

var camera1 : Camera;
var camera2 : Camera;

function Start () {
   camera1.enabled = true;
   camera2.enabled = false;
}

function Update () {
   if (Input.GetKeyDown ("2")){
      camera1.enabled = false;

      camera2.enabled = true;
   }
   if (Input.GetKeyDown ("1")){
      camera1.enabled = true;
      camera2.enabled = false;
   }  
}
Para cambiar entre varias cámaras con un mismo botón (en este caso con la tecla "C" y con 4 cámaras):


var camera1 : Camera;
var camera2 : Camera;
var camera3 : Camera;
var camera4 : Camera;
public var startCamera : int = 1;

function Start ()
{
   camera1.enabled = true;
   camera2.enabled = false;
   camera3.enabled = false;
   camera4.enabled = false;
   startCamera = 1;
}

function Update ()
{
   if (Input.GetKeyDown ("c") && (startCamera == 1))
   {
      startCamera = 2;
      camera1.enabled = false;
      camera2.enabled = true;
      camera3.enabled = false;
      camera4.enabled = false;
   }
 
   else if (Input.GetKeyDown ("c") && (startCamera == 2))
   {
      startCamera = 3;
      camera1.enabled = false;
      camera2.enabled = false;
      camera3.enabled = true;
      camera4.enabled = false;
   }
 
   else if (Input.GetKeyDown ("c") && (startCamera == 3))
   {
      startCamera = 4;
      camera1.enabled = false;
      camera2.enabled = false;
      camera3.enabled = false;
      camera4.enabled = true;
   }
 
   else if (Input.GetKeyDown ("c") && (startCamera == 4))
   {
      startCamera = 1;
      camera1.enabled = true;
      camera2.enabled = false;
      camera3.enabled = false;
      camera4.enabled = false;
   }
 
}
