The goal of this book is to get readers who are new to game AI to the point where they can usefully consume ‘‘regular’’ books on game AI. It is aimed at those who do not have a hard-core programming background, particularly those coming from other areas of game development. The book achieves this through a series of projects based on small and understandable games. Because AI is about decision making, the projects and topics selected for the book are measured against the question, ‘‘Can a beginner understand the decision-making process?’’ The projects may present some challenges, but with the help of this book, beginners should always be able to say, ‘‘I might have trouble getting the AI to act, but I have no trouble getting the AI to decide.’’
