Hands-On Unity 2020 Game Development

By: Nicolas Alejandro Borromeo

Overview of this book

Over the years, the Unity game engine has extended its scope from just being about creating video games to building AR/VR experiences, complex simulations, real-time realistic rendering, films, and serious games for training and education. Its features for implementing gameplay, graphics, and customization using C# programming make Unity a comprehensive platform for developing professional-level, rich experiences. With this book, you'll be able to build impressive Unity projects in a step-by-step manner and apply your knowledge of Unity concepts to create a real-world game. Complete with hands-on tutorials and projects, this easy-to-follow guide will show you how to develop your first complete game using a variety of Unity tools. As you make progress, you'll learn how to make the most of the Unity Editor and create scripts using the C# programming language. This Unity game development book will then take you through integrating graphics, sound, and animations and manipulating physics to create impressive mechanics for your games. You'll also learn how to code a simple AI agent to challenge the user and use profiling tools to ensure that the code runs in a performant way. Finally, you'll get to grips with Unity's AR Foundation for creating AR experiences for 3D apps and games. By the end of this book, you'll have developed a complete game and will have built a solid foundation using Unity's tooling ecosystem to develop game projects of any scale.

Creating C# scripts

This book is intended for readers with some programming knowledge, but in this first section, we are going to discuss the C# script structure to make sure you have a strong foundation for the behaviors we will code in the following chapters.

In this section, we will examine the following script creation concepts:

  • Initial setup
  • Creating a MonoBehaviour-based class
  • Adding fields

We are going to create our first Unity script, which will serve to create our component, discussing the tools needed to do so and exploring how to expose our class fields to the editor. Let's start with the basics of script creation.

Initial setup

One thing to consider before creating our first script is how Unity compiles code. While coding, we are used to having an Integrated Development Environment (IDE), which is a program to create our code and compile or execute it. In Unity, we will just use an IDE as a tool to create scripts easily with coloring...
