Time for action – displaying the time on-screen

We know from the Debug statements that the clock is working, so all we need to do is stick the timeRemaining value into our GUIText to see it on the screen. But, it won't look very clock-like unless we perform a tiny bit of math on that value to split it into minutes and seconds, so that five seconds displays as 0:05, or 119 seconds displays as 1:59.

1. Call the ShowTime() function from within the DoCountdown() function (you can delete or comment the Debug.Log() statement):

   function DoCountdown()
   {
     timeRemaining = startTime - Time.time;
     // (other lines omitted for clarity)
     ShowTime();
     //Debug.Log("time remaining = " + timeRemaining);
   }

2. Create some variables to store the minutes and seconds values in the ShowTime() function, along with a variable to store the string (text) version of the time:

   function ShowTime() {
      var minutes : int;
      var seconds : int;
      var timeStr : String;
   }

3. Just below that, divide the timeRemaining by 60 to get the...
