Purpose of this document
This is a technical document describing the UnrealScript language. It's not a tutorial, nor does it provide detailed examples of useful UnrealScript code. For examples of UnrealScript prior to release of Unreal, the reader is referred to the source code to the Unreal scripts, which provides tens of thousands of lines of working UnrealScript code which solves many problems such as AI, movement, inventory, and triggers. A good way to get started is by printing out the "Actor", "Object", "Pawn", "Inventory", and "Weapon" scripts.
This document assumes that the reader has a working knowledge of C/C++, is familiar with object-oriented programming, has played Unreal and has used the UnrealEd editing environment.
For programmers who are new to OOP, I highly recommend going to Amazon.com or a bookstore and buying an introductory book on Java programming. Java is very similar to UnrealScript, and is an excellent language to learn about due to its clean and simple approach.
