I’m trying to have it switch between 2 maps with the push of a button it goes one way but not the other.

#pragma strict
var old : 	byte ;
function Start () {
	old = 0;
}

function Update () {
 if (Input.GetKeyDown ("r")) { 
  if (old == 1){
   transform.Translate(Vector3.left * 1000, Space.World);
   old = 0;
 }
  if (old == 0){
   transform.Translate(Vector3.right * 1000, Space.World);
   old = 1;
  }
 }
 
};

First of all Unity never supported

(https://en.wikipedia.org/wiki/Java_(programming_language)). Unity supports **Unityscript**, a language implementing the [ECMA specification](https://en.wikipedia.org/wiki/ECMAScript), making it similar to **Javascript**.

Here is the correct script


    #pragma strict
    var old : byte ;
    function Start()
    {
        old = 0;
    }
    
    function Update()
    {
        if ( Input.GetKeyDown( "r" ) )
        {
            if ( old == 1 )
            {
                transform.Translate( Vector3.left * 1000, Space.World );
                old = 0;
            }
            else if ( old == 0 ) // The else here is important
            {
                transform.Translate( Vector3.right * 1000, Space.World );
                old = 1;
            }
        }
    }
