Unity 2018 Artificial Intelligence Cookbook - Second Edition

By: Jorge Palacios

Overview of this book

Interactive and engaging games come with intelligent enemies, and this intellectual behavior is combined with a variety of techniques collectively referred to as Artificial Intelligence. Exploring Unity's API, or its built-in features, allows limitless possibilities when it comes to creating your game's worlds and characters. This cookbook covers both essential and niche techniques to help you take your AI programming to the next level. To start with, you’ll quickly run through the essential building blocks of working with an agent, programming movement, and navigation in a game environment, followed by improving your agent's decision-making and coordination mechanisms – all through hands-on examples using easily customizable techniques. You’ll then discover how to emulate the vision and hearing capabilities of your agent for natural and humanlike AI behavior, and later improve the agents with the help of graphs. This book also covers the new navigational mesh with improved AI and pathfinding tools introduced in the Unity 2018 update. You’ll empower your AI with decision-making functions by programming simple board games, such as tic-tac-toe and checkers, and orchestrate agent coordination to get your AIs working together as one. By the end of this book, you’ll have gained expertise in AI programming and developed creative and interactive games.

Implementing NegaScout

Including a search strategy also makes room for new challenges. NegaScouting is the result of narrowing the search by improving the pruning heuristic. It is based on a concept called search window, which is the interval between the alpha and beta values. So, reducing the search window increases the chance of a branch being pruned.

Getting ready...

It is important to know the difference between a dynamic member function and a static member function, as well as recursion. A dynamic member function is bound to the instance of the class, while the static member function is bound to the class itself. The static method allows us to call it without instantiating an object. This is great for general-purpose...
