Time for action – Using the for statement

1. Let's examine the following code:

   var int m;
   
   function PostBeginPlay()
   {
       for(m = 0; m < 3; m++)
       {
           'log("Stop hitting yourself." @ m);
       }
   }

   This is a simple way of writing the following code:

   m = 0;
   'log(m);
   m = 1;
   'log(m);
   m = 2;
   'log(m);

It might not seem like it's saving much time in this simple example, but consider a case where we would want to run the loop a hundred times. Putting it in a for loop would save a lot of unnecessary code!

If we write the PostBeginPlay function above into our AwesomeActor.uc class and compile it, then take a look at the log, we can see that it executed the code inside the for loop three times:

[0007.57] ScriptLog: Stop hitting yourself. 0
[0007.57] ScriptLog: Stop hitting yourself. 1
[0007.57] ScriptLog: Stop hitting yourself. 2

What just happened?

The first part of the for statement lets us set a variable to an initial value. Most of the time it will be 0, but there may be times when we need a different...
