Welcome to Unreal Development Kit Game Programming with UnrealScript! This book teaches you how to program using the UnrealScript language so you can create your own game projects using the UDK. Instead of using dry, hypothetical code you will use the topics learned in each chapter to build an actual working game. By the end of the book, you will be comfortable enough with the language to start working on projects of your own.

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.

What you will learn from this book

• Set up a UDK project and learn how to compile and test your own code
• Learn how to extend the UDK's code to add your own functionality
• Create your own game types, player camera, and HUD
• Learn how UnrealScript interacts with Kismet and create your own Kismet actions and events
• Use networking to create and test multiplayer games
• Optimize your code to fix errors and performance problems
• Use DLLBind to interact with code outside of the UDK

Approach

This is a step-by-step book that builds on your knowledge by adding to an example game over the course of each chapter. Each topic uses example code that can be compiled and tested to show how things work instead of just telling you. Complicated tasks are broken down into easy to follow steps with clear explanations of what each line of code is doing.
