Time for action – Misleading errors

Sometimes error messages might seem a little misleading, as we'll see in this next experiment:

1. Let's rewrite our PostBeginPlay function. We'll leave in our MyInt variable and use it for this experiment:

   simulated function PostBeginPlay()
   {
       if(UTGame(WorldInfo.Game != none)
           MyInt = UTGame(WorldInfo.Game).DefaultMaxLives;
   }

2. Seems fine, but when we try to compile we get this error:

   [0004.84] Log: R:\UDK\UDK-AwesomeGame\Development\Src\BrokenGame\Classes\BrokenActor.uc(8) : Error, Bad or missing expression for token: UTGame, in 'If'

   What could this mean? It seems to be telling us that it doesn't know what UTGame is, even though it's a valid class. If we take a closer look at our if statement, we can see the problem:

       if(UTGame(WorldInfo.Game != none)

   I'm counting two open parentheses, but only one closed one. If we take the if part out of this line and examine it separately:

       UTGame(WorldInfo.Game != none)

   To the compiler, it looks like we're trying...
