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


In the previous example, we created lots of copies of our enemy around the scene, but in doing so, we have created a new problem. Let's imagine we need to change our enemy and add a Rigidbody component to it, but because we have several copies of the same object, we need to take them one by one and add the same component to all of them. Maybe later, we will need to change the mass of each enemy, so again, we need to go over each one of the enemies and make the change, and here we can start to see a pattern.

One solution could be to select all the enemies using the Ctrl key (option on a Mac) and modify all of them at once, but that solution won't be of any use if we have enemy copies in other scenes. So, here is where Prefabs come in.

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

  • Creating Prefabs
  • Prefab-instance relationship
  • Prefab variants

Creating Prefabs

A Prefab is a Unity tool that allows us to convert...
