Hands-On Unity 2021 Game Development - Second Edition

By: Nicolas Alejandro Borromeo

Overview of this book

Learning how to use Unity is the quickest way to creating a full game, but that’s not all you can do with this simple, yet comprehensive suite of video game development tools – Unity is just as useful for creating AR/VR experiences, complex simulations, real-time realistic rendering, films, and practical games for training and education. Hands-On Unity 2021 Game Development outlines a practical journey to creating your first full game from the ground up, building it step-by-step and applying your knowledge as you progress. Complete with hands-on tutorials and projects, this easy-to-follow guide will teach you how to develop the game using several Unity tools. As you advance, you will learn how to use the Unity engine, create simple scripts using C#, integrate graphics, sound, and animations, and manipulate physics to create interesting mechanics for your game. You’ll be able to apply all the knowledge that you gain to a real-world game. Later chapters will show you how to code a simple AI agent to challenge the user and use profiling tools to ensure that the code runs efficiently. Finally, you'll work with Unity's AR tools to create AR experiences for 3D apps and games. By the end of this Unity book, you will have created a complete game and built a solid foundation in using a wide variety of Unity tools.

GameObjects and components

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

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

  • Understanding components
  • Manipulating components

Let's start by discussing what a component is.

Understanding components

A component is one of several pieces a GameObject can be made of; each one is in charge of different features of the object. There are several components that Unity already includes that solve different tasks, such as playing a sound, rendering a mesh, applying physics, and so on; however, even though Unity has a large number of components, we will eventually need to create custom components, sooner or later.

In the next screenshot, you can see what Unity shows us when we select a GameObject.
