Sub-Archetype

Currectly there's no much information about sub-archetype on UDN, so I'd like to share some I know.

An archetype is an instance of a centain class, its properties inherit the class default values but you can change them as you wish. If its property values do not change but the class default values do, the property values will change accordingly. If its property values change, then they will stick to the modified values as the class default values change. You can create an archetype in the Actor Classes Browser.

Setting up a UnrealScript project in Visual Studio

nFringe is a plug-in for Visual Studio to support UnrealScript. It allows you to create UnrealScript projects, and it supports IntelliSense and the debugger in Visual Studio. It has a commercial license and a non-commercial one. You can register a non-commercial license without charge, and it allows you to use all functions with UDK. For a UnrealScript scripter using UDK, it is definitely worthy to give it a shot.

Installation

UnrealScript Beginner's Guide

UnrealScript is the script language provided by Unreal Engine. It allows you to move your characters and cameras, play animation and special effects, even draw HUD. A UDK user only need a text editor to code in UnrealScript. When you start UDK, it will check if UnrealScript code has been modified. When you finish coding and want to test it, you can just restart UDK to recompile UnrealScript. This note will show you how to code with this simple approach.

Writing Scripts

Once you finish installing UDK, you can find UnrealScript files in the "Development\Src\UTGame\Classes" folder. Open "UTCheatManager.uc" with your text editor, and insert the following code snippet into the end of the file:

exec function SetGroundSpeed(float NewSpeed)
{
    Pawn.GroundSpeed = NewSpeed;
}
