Unity 2017 Game AI Programming - Third Edition - Third Edition

Overview of this book

Unity 2017 provides game and app developers with a variety of tools to implement Artificial Intelligence. Leveraging these tools via Unity's API or built-in features allows limitless possibilities when it comes to creating your game's worlds and characters. This third edition with Unity will help you break down Artificial Intelligence into simple concepts to give you a fundamental understanding of the topic to build upon. Using a variety of examples, the book then takes those concepts and walks you through actual implementations designed to highlight key concepts, and features related to game AI in Unity 5. Further on you will learn to distinguish the state machine pattern and implement one of your own. This is followed by learning how to implement a basic sensory system for your AI agent and coupling it with a Finite State Machine (FSM). Next you'll learn how to use Unity's built-in NavMesh feature and implement your own A* pathfinding system. You will then learn how to implement simple flocks and crowd's dynamics, key AI concepts. Moving on, you will learn how to implement a behavior tree through a game-focused example. Lastly, you'll combine fuzzy logic concepts with state machines and apply all the concepts in the book to build a simple tank game.

The morality meter example

The faction/morality meter example for this chapter covers a slightly different approach to implementing fuzzy logic via Unity. We build upon the implementation we covered in the basic fuzzy logic example.

In this example, we create a simple dialogue sequence, where the player is presented a series of scenarios, or questions, that they can then answer according to their morality. For simplicity's sake, we've included a "good," "neutral," and "evil" answer for each question. Let's take a look at the code to understand this a bit better.

The question and answer classes

The Question and Answer classes are very simple, and are used as data containers. Let...
