To get the most out of this book

Anyone with a strong programming background will be able to get the most out of this book. However, readers that also have strong foundations in comp-sci will benefit greatly from the set of implementations in Unity.

Before you start, it is important to know about programming, data structures, and the basic foundations of C#. We assume that you feel comfortable creating scripts components in Unity, and have developed some prototypes in the past.

We believe that you will get the most out of this book if you already have an idea of the modules for beginner and intermediate gameplay scripting available at https://unity3d.com/learn/tutorials/s/scripting.

We have developed this book using Unity, Visual Studio Community, and Visual Studio Code. The latter shows better performance and behaves in the same way in Windows and Mac operating systems. The first would be our choice for a Windows-only development environment.

Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "Agent is the main component, and it makes use of behaviors in order to create intelligent movement."

A block of code is set as follows:

public override void Awake() 
{ 
    base.Awake(); 
    targetAgent = target.GetComponent<Agent>(); 
    targetAux = target; 
    target = new GameObject(); 
} 

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

public override void Awake() 
{ 
    base.Awake(); 
    targetAgent = target.GetComponent<Agent>(); 
    targetAux = target; 
    target = new GameObject(); 
} 

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "We also need to have the Agent script component attached to them"
