It's the ability to write custom C# scripts for behaviors and game mechanics that really takes Unity the extra mile. That's where this book will help you as a new programmer!
Harrison Ferrone, in this eighth edition of the bestselling series, will take you through the core concepts of programming and the C# language from scratch, while building an engaging and playable game prototype in Unity 6.
You'll get to grips with the fundamentals of object-oriented programming (OOP) and the Unity engine with lots of code samples, exercises, and tips to go beyond the book with your work. You'll write C# scripts for simple game mechanics, perform procedural programming, request live data from the web, and add complexity to your games by introducing intelligent enemies and damage-dealing projectiles. You'll also explore the underlying mechanics of Unity game development, including game design, lighting basics, player movement, camera controls, collisions, and more, with every passing chapter.

Preface

Unity is one of the most popular game engines in the world, catering to hobbyists, professional AAA studios, and cinematic production companies. While known for its use as a 3D tool, Unity has a host of dedicated features supporting everything from 2D games and virtual reality to post-production and cross-platform publishing.

Developers love its drag-and-drop interface and built-in features, but it’s the ability to write custom C# scripts for behaviors and game mechanics that really takes Unity the extra mile. Learning how to write C# code might not be a huge obstacle to a seasoned programmer with other languages under their belt, but it can be daunting for those of you who have no programming experience. That’s where this book comes in, as I’ll be taking you through the building blocks of programming and the C# language from scratch while building a fun and playable game prototype in Unity.

Who this book is for

This book is written for those of you who don’t have any experience with the basic tenets of programming or C#. However, if you’re a competent novice or seasoned professional coming from another language, or even C#, but need to get hands-on with game development in Unity, this is still where you want to be.

What this book covers

, , starts off with the Unity installation process, the main features of the editor, and finding documentation for C# and Unity-specific topics. We’ll also go through creating C# scripts from inside Unity and look at Visual Studio, the application where all our code editing takes place.

, , begins by laying out the atomic-level concepts of programming, giving you the chance to relate variables, methods, and classes to situations in everyday life. From there, we’ll move on to simple debugging techniques, proper formatting and commenting, and how Unity turns C# scripts into components.

, , takes a deeper look at the building blocks from . This includes C# data types, naming conventions, access modifiers, and everything else you’ll need for the foundation of a program. We’ll also go over how to write methods, add parameters, and use return types, ending with an overview of standard Unity methods belonging to the class.

, , introduces the common approaches to making decisions in code, consisting of the and statements. From there, we’ll move on to working with arrays, lists, and dictionaries, and incorporating iteration statements for looping through collection types. We’ll end the chapter with a look at conditional looping statements and a special C# data type called enumerations.

, , details our first contact with constructing and instantiating classes and structs. We’ll go through the basic steps of creating constructors, adding variables and methods, and the fundamentals of subclassing and inheritance. The chapter will end with a comprehensive explanation of object-oriented programming (OOP) and how it applies to C#.

, , marks our departure from C# syntax into the world of game design, level building, and Unity’s featured tools. We’ll start by going over the basics of a game design document and then move on to blocking out our level geometry and adding lighting and a simple particle system.

, , explains different approaches to moving a player object and setting up a third-person camera. We’ll discuss incorporating Unity physics for more realistic locomotion effects, as well as how to work with collider components and capture interactions within a scene.

, , introduces the concept of game mechanics and how to effectively implement them. We’ll start by adding a simple jump action, creating a shooting mechanic, and building on the previous chapters’ code by adding logic to handle item collection.

, , starts with a brief overview of artificial intelligence (AI) in games and the concepts we will be applying to . Topics covered in this chapter will include navigation in Unity, using the level geometry and a navigation mesh, smart agents, and automated enemy movement.

, , takes a more in-depth look at data types, intermediate method features, and additional behaviors that can be used for more complex classes. This chapter will give you a deeper understanding of the versatility and breadth of the C# language.

, , dives into stacks, queues, hash sets, and the different development scenarios that each is uniquely suited for. This chapter also explores filtering, ordering, and transforming data collections using LINQ.

, , gets you ready to handle your game’s information. Topics covered in this chapter include working with the filesystem and creating, deleting, and updating files. We’ll also cover different data types, including XML, JSON, and binary data, and end with a practical discussion on serializing C# objects directly into data formats.

, , introduces the basics of web requests, downloading data from web servers, and turning that information into actionable game mechanics. We’ll also cover the differences between synchronous and asynchronous code and how Unity handles both.

, , details intermediate features of the C# language and how to apply them in practical, real-world scenarios. We’ll start with an overview of generic programming and progress to concepts such as delegation, events, and exception handling.

, , reviews the main topics you’ve learned throughout the book and leaves you with resources for further study in both C# and Unity. Included in these resources will be online reading material, certifications, and a host of my favorite video tutorial channels.

To get the most out of this book

The only thing you need to get the most from your upcoming C# and Unity adventure is a curious mind and a willingness to learn. Having said that, doing all the code exercises, , and sections is a must if you hope to cement the knowledge you’re learning. Lastly, revisiting topics and entire chapters to refresh or solidify your understanding before moving on is always a good idea. There is no sense in building a house on an unstable foundation.

You’ll also need a current version of Unity installed on your computer—version 6.0 or later is recommended. All code examples have been tested with Unity 6000.0.50f1 and should work with future versions without issues.

This is the software/hardware covered in the book:

• Unity 6.0 or later
• Visual Studio 2019 or later
• C# 9.0 or later

Before starting, check that your computer setup meets the Unity system requirements at https://docs.unity3d.com/6000.0/Documentation/Manual/system-requirements.html.
