Time for action – Setting up a twofer

Another obvious error, with a twist!

1. Let's rewrite our PostBeginPlay function:

   simulated function PostBeginPlay()
   {
       var int AnotherInt;
   
       AnotherInt = class'UTGame'.default.CountDown;
   }

2. Looks fine this time, we have our brackets, parentheses, and semicolons in place. What could go wrong?

   [0003.93] Log: R:\UDK\UDK-AwesomeGame\Development\Src\BrokenGame\Classes\BrokenActor.uc(8) : Error, Instance variables are only allowed at class scope (use 'local'?)

3. Oh, right. Inside functions we're only allowed to use local variables. Let's fix that real quick:

   simulated function PostBeginPlay()
   {
       local int AnotherInt;
   
       AnotherInt = class'UTGame'.default.CountDown;
   }

4. Now it should work, so let's compile it:

   [0004.08] Log: R:\UDK\UDK-AwesomeGame\Development\Src\BrokenGame\Classes\BrokenActor.uc(10) : Warning, 'AnotherInt' : unused local variable

5. Well this is new, a warning this time instead of an error! Unused local variable. We're assigning a value to it, but...
