Time for action – preparing the clock code

Let's rough in a few empty functions and three variables that we'll need to make the clock work.

1. Open up the ClockScript by double-clicking on it. Update the code:

   #pragma strict
   var clockIsPaused : boolean = false;
   var startTime : float; //(in seconds)
   var timeRemaining : float; //(in seconds)
   function Awake()
   {
   }
   
   function Update() {
     if (!clockIsPaused)
     {
        // make sure the timer is not paused
        DoCountdown();
     }
   }
   
   function DoCountdown() {
   }
   
   function PauseClock()
   {
      clockIsPaused = true;
   }
   function UnpauseClock()
   {
      clockIsPaused = false;
   }
   
   function ShowTime()
   {
   }
   
   function TimeIsUp()
   {
   }
   

What just happened – that's a whole lotta nothing

Here, we've created a list of functions that we'll probably need to get our clock working. The functions are mostly empty, but that's okay—roughing them in like this is a really valid and useful way to program. We have a DoCountdown() function that we call on every update, as long as our clockIsPaused...
