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

GameObjects and components

We talked about our project being composed of Assets, and that a Scene (a specific type of Asset) is composed of GameObjects; so, how can we create an object? Through the composition of components.

In this section, we will cover the following concepts related to components:

  • Components
  • Manipulating components


A component is one of several pieces a Game Object can be made of; each one is in charge of different features of the object. There are several components that solve different tasks, such as playing a sound, rendering a mesh, applying physics, and so on, and even if Unity has a large number of components, we will eventually need to create custom components, sooner or later. In the following screenshot, you can see what Unity shows us when we select a Game Object:
