Overview of this book

UDK is a free, world class game editing tool and being so powerful it can be daunting to learn. This guide offers an excellent set of targeted recipes to help game artists get up to speed with game designing in UDK.Unreal Development Kit Game Design Cookbook contains everything you need to jumpstart your game design efforts. The lessons are aimed squarely at the artist's field of production, with recipes on asset handling, creating content within the editor, animation and visual scripting to get the content working in gameplay.Unreal Game Development Kit Game Design Cookbook exposes how real-time environments are built using UDK tools. Key features are examined ñ assets, animation, light, materials, game controls, user interface, special effects, and game interactivity - with the view of making UDK technically accessible so users can transcend technique and focus on their creative design process. The book has well prepared recipes for level designers and artists of all levels. It covers core design tools and processes in the editor, particularly setting up characters, UI approaches, configuration and scripting gameplay. It is a technical guide that allows game artists to go beyond just creating assets, and it includes creative, extensive demonstrations that extend on mere functionality.

Ways to stop a recurring loop


In the previous recipe we created a swap between two Bots called Gremlin and Zombie. We can perform this swap all day and all night. Being able to jump back and forth forever might be a good dynamic in some games, but you might want to build in a way to prevent the swapping at a certain point, perhaps when a quest goal is reached or a mission objective achieved. It would be good to show how to interrupt the possession sequence. In this recipe we'll try out two methods, a New Action | Switch | Switch action and a New Action | Misc | AND Gate.

If Zombie shoots the gate shown here and dawn has arrived, the possession mechanism we set up in the previous recipe will stop. Instead a sliding gate (provisioned by a prefab) will open and Gremlin will start shooting at Zombie. There's our reason to use an AND Gate as both events must occur first. The problem is, as soon as the level begins it is dawn, we want to limit things so they player has to wait through the night...
