turning script on after time

i've created this script:

var lifeTime = 1.0;

function Awake ()

{

    if (lifeTime <=0)

    {

    GetComponent("AI script Looking").enabled = true;

    }

}

there are no errors but it doesn't work at all, i want it to turn on after time... thanks all :D

Where does lifeTime change? It's never negative. Try this (there are many ways to do this):

var delay = 1.0;
var startTime = 0.0;

function Awake()
{
  startTime = Time.time;
}

function Update ()
{
    if ((Time.time - startTime) >= delay)
    {
      GetComponent("AI script Looking").enabled = true;
    }
}
