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.

Chapter 20: Building the Project

Using events and instructions

Now that we have a script, we are ready to do something with it. We won't implement anything useful in this chapter, but we will settle the concepts to add some types of behavior for the scripts we are going to create in the next chapters.

In this section, we are going to cover the following concepts:

  • Events and instructions
  • Using fields in instructions
  • Common beginner errors

We are going to explore the Unity event system, which will allow us to respond to these situations by executing Unity functions. These functions will also be affected by the value of the editor, and fields exposed to our script will be configurable. Finally, we are going to discuss common scripting errors and how to solve them. Let's start by introducing the concept of Unity events.

Events and instructions

Unity allows us to create behavior in a cause-effect fashion, which is usually called an event system. An event is a situation that Unity...
