UDK Racing Game - Gameplay Design

This Unreal Development Kit training module covers the gameplay design and playtesting aspect of a downhill racing game project. Learn how to create an enemy bot and make it drive a vehicle through the level using Pathnodes. Use UDK tools such as Kismet and Matinee to create simple connections and animations that help your level to function properly. Add damage triggers that will hurt the player if they drive off the track. Create 3D text for your level and a menu background for when the game starts. Finally, cook and package your level so that it can run from a standalone executable file. This is the second of two modules in the “UDK Racing Game” series.
