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.

What this book covers

Chapter 1, Designing a Game from Scratch, discusses the details of the game we are going to create in the book before even opening Unity for the first time, outlining the Unity features to use.

Chapter 2, Setting Up Unity, teaches you how to install and set up Unity on your computer, and also how to create your first project.

Chapter 3, Working with Scenes and Game Objects, teaches you the concepts of Scenes and GameObjects, the Unity way to describe what your game world is composed of.

Chapter 4, Grayboxing with Terrain and ProBuilder, is where we will be creating our first level layout, prototyping it with the Terrain and ProBuilder Unity features.

Chapter 5, Importing and Integrating Assets, teaches you how to improve your scene art by importing graphics into Unity, as Unity is not a tool for creating graphics but for displaying them.

Chapter 6, Materials and Effects with URP and Shader Graph, shows how to use one of the latest Unity Render Systems (Universal Render Pipeline) and how to create effects with the Shader Graph feature.

Chapter 7, Visual Effects with Particle Systems and Visual Effect Graph, teaches you how to create visual effects such as water and fire using the two main Unity tools for doing so, Particle Systems and VFX Graph.

Chapter 8, Lighting Using the Univeral Render Pipeline, looks at lighting, which is a concept big enough to have its own chapter. Here, we will deepen our knowledge of the Universal Render Pipeline, specifically its lighting capabilities.

Chapter 9, Fullscreen Effects with Postprocessing, teaches you how to add a layer of effects on top of your scene graphics using the Postprocessing feature of the Universal Render Pipeline to get that film effect most modern games have today.

Chapter 10, Sound and Music Integration, covers a topic that is underestimated by most beginner developers; here we will learn how to properly add sound and music to our game, taking into consideration its impact on performance.

Chapter 11, User Interface Design, looks at the User Interface (UI). Of all the graphical ways to communicate information to the user, the UI is the most direct one. We will learn how to display information in the form of text, images, and life bars using the Unity UI system.

Chapter 12, Creating a UI with the UI Toolkit, looks at UI Tookit, which, since Unity 2021, is a soon-to-be successor of Canvas, the UI system we learned about in Chapter 11, User Interface Design. We will explore it to get ahead and be prepared for Unity's use of this HTML-based toolkit in the future.

Chapter 13, Creating Animations with Animator, Cinemachine, and Timeline, takes us further than the static scene we have created so far. In this chapter, we will start moving our characters and creating cutscenes with the latest Unity features to do so.

Chapter 14, Introduction to C# and Visual Scripting, is the first programming chapter of the book. We will learn how to create our first script using C# in the Unity way, and then we will explore how to do the same with Visual Scripting, the new node-based coding language of Unity. The rest of the programming chapters will show how to code the game in both languages.

Chapter 15, Implementing Movement and Spawning, teaches you how to program the movement of your objects and how to spawn them. General programming knowledge is assumed from now on.

Chapter 16, Physics Collisions and Health System, teaches you how to configure the Physics settings of objects to detect when two of them collide and react to the collision, creating a Health System, in this case.

Chapter 17, Win and Lose Condition, covers how to detect when the game should end, both when the player wins and loses.

Chapter 18, Scripting the UI, Sounds, and Graphics, covers how to make the UI show the current information of the game, such as the Player's Health and Score. Also, sounds will be played when necessary, and visual effects will reflect the actions of the Player.

Chapter 19, Implementing Game AI for Building Enemies, covers creating a basic AI using several Unity features for creating challenging enemies in our game.

Chapter 20, Scene Performance Optimization, discusses how making our game perform well is no easy task, but is certainly needed to release it. Here, we will be learning how to profile our game's performance and tackle the most common performance issues.

Chapter 21, Building the Project, teaches you how to convert your Unity project into an executable format to distribute it to other people and run it without Unity installed.

Chapter 22, Finishing Touches, briefly discusses how to move forward with the development of our game after finishing this book, discussing topics such as how to iterate and release the game.

Chapter 23, Augmented Reality in Unity, teaches you how to create an AR application with Unity's AR Foundation package, one of the most recent ways to create AR applications with Unity.
