As an example of what NOT to do, let's take this code.
var int Int1; function PostBeginPlay() { Int1 = 5; While(Int1 > 0) { Int1 = 5; } }
When we run the game with this code, it will crash.
It is EXTREMELY IMPORTANT to always make sure the "while" condition will be met to avoid infinite loop crashes.
Let's take a look at the right way to use it:
var int Int1; function PostBeginPlay() { While(Int1 < 5) { 'log("Int1" @ Int1); Int1++; } }
In this case,
Int1
will keep incrementing until it reaches 5, and the While loop will exit.We could also use a statement called
break
to exit the loop:var int Int1; function PostBeginPlay() { While(Int1 < 5) { 'log("Int1" @ Int1); Int1++; if(Int1 == 3) break; } }
In this case, the loop will exit when
Int1
reaches 3 instead of continuing until it hits 5.Another statement we can use is called continue. Instead of exiting the loop...

Overview of this book
Unreal Development Kit is the free edition of Unreal Engine—the largest game engine in existence with hundreds of shipped commercial titles. The Unreal Engine is a very powerful tool for game development but with something so complex it's hard to know where to start.This book will teach you how to use the UnrealScript language to create your own games with the Unreal Development Kit by using an example game that you can create and play for yourself. It breaks down the UnrealScript language into easy to follow chapters that will quickly bring you up to speed with UnrealScript game programming.Unreal Development Kit Game Programming with UnrealScript takes you through the UnrealScript language for the Unreal Development Kit. It starts by walking through a project setup and setting up programs to write and browse code. It then takes you through using variables, functions, and custom classes to alter the game's behavior and create our own functionality. The use and creation of Kismet is also covered. Later, using replication to create and test multiplayer games is discussed. The book closes with code optimization and error handling as well as a few of the less common but useful features of UnrealScript.
