Build immersive game experiences using the new Unity 2020 features with this practical guide

▶Book Description
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.

▶What You Will Learn
？Write scripts for customizing various aspects of a game, such as physics, gameplay, and UI

？Add animations to your game using the Animator, Cinemachine, and Timeline
？Implement game artificial intelligence (AI) to control character behavior
？Detect and fix optimization issues using profilers and batching

▶Key Features
？Unleash the capabilities of C# scripting for creating immersive UI, graphics, Game AI agents and much more
？Explore Unity's latest tools, including Universal Render Pipeline, Shader Graph, and VFX graph, to enhance graphics and animation
？Get started with building augmented reality experience using Unity's AR Foundation

▶Who This Book Is For
This book is for game developers looking to migrate to the Unity game engine. If you are a developer with some exposure to Unity, this book will help you explore its latest features. Prior experience with C# programming is required to get the most out of the book.

▶What this book covers
？ Chapter 1, Designing a Game from Scratch, is where we will discuss the details of the game we are going to create in the book before even opening Unity for the first time.

？ Chapter 2, Setting Up Unity, is where you will learn how to install and set up Unity on your computer, and is also where you will create your first project.

？ Chapter 3, Working with Scenes and GameObjects, is where we will learn about the concepts of Scenes and GameObjects, which are part of Unity's way of describing what your game world is composed of.

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

？ Chapter 5, Importing and Integrating Assets, introduces graphics. As Unity is not a tool for creating graphics, but for displaying them, we will learn how to improve our Scene art by importing graphics into Unity.

？ Chapter 6, Materials and Effects with URP and Shader Graph, is where we will see 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 VFX Graph, is where you will learn how to create visual effects, for things such as water and fire, using the two main Unity tools for doing so: Particle Systems and the VFX Graph.

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

？ Chapter 9, Fullscreen Effects with Post-Processing, delves into effects and post-processing. To get that cinematic effect that most modern games have today, we will learn how to add a layer of effects on top of our Scene graphics using the post-processing feature of the Universal Render Pipeline.

？ Chapter 10, Sound and Music Integration, gets into an often-neglected area: sound. Being 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, explores the use of the user interface (UI). Of all the graphic-based ways to communicate information to the user, the use of the UI is the most direct. We will learn how to display information in the form of text, images, and life bars using the Unity UI system.

？ Chapter 12, Creating Animations with Animator, Cinemachine, and Timeline, moves us on from our simple static Scene. In this chapter, we will start moving our characters with animations and creating cutscenes with the latest Unity features for doing so.

？ Chapter 13, Introduction to Unity Scripting with C#, is the first programming chapter of the book. We will learn how to create our first script using C# in the Unity way.

？ Chapter 14, Implementing Movement and Spawning, is where we will learn how to program the movement of our objects and how to spawn them. General programming knowledge is assumed from now on.

？ Chapter 15, Physics Collisions and Health System, is where you will learn how to configure the physics settings of objects to detect when two of them collide and react to the collision. To put this in practice, we'll be creating a health system.

？ Chapter 16, Win and Lose Conditions, is where we will be detecting when the game should end, which will be when the player either wins it or loses it.

？ Chapter 17, Scripting the UI, Sounds, and Graphics, is where we will be making the previously created UI to show the relevant and current information of the game, such as the player's health and the score. Also, we'll look at sounds being played when necessary and the use of visual effects to reflect the actions of the player.

출판사 서평

▶ Preface
I still remember that moment of my life when I was afraid of telling my parents that I was going to study game development. At that time and where I was, that was considered a childish desire by most parents, and a career with no future, but I was stubborn enough to not care and to follow my dream. Today, game development is one of the biggest industries, generating more revenue than even the film industry.

Of course, following my dream was more difficult than I thought. Sooner or later, people chasing this particular dream have to face the fact that developing games is a difficult task that requires a deep level of knowledge in different areas. Sadly, most people give up due to this difficulty level, but I strongly believe that with proper guidance and tools, you can make your career path easier for you to follow. In my case, what helped me to flatten the learning curve was learning using Unity.

Welcome to this book about Unity 2020. Here you will learn how to use the most recent Unity features to create your first video game in the simplest way possible. Unity is a tool that provides you with powerful but easy-to-use features to solve the most common problems in game development, such as rendering, animation, physics, sound, effects, and so on. We will be using all those features to create a simple but complete game, learning all the nuances needed to handle Unity.

By the end of this book, you will be able to use Unity in a way that will allow you to start studying in depth that area of game development that you are interested in starting your career in, or that will simply allow you to create hobby games just for the joy of doing it. Unity is a versatile tool that can be used both in professional and amateur projects, and every day it is being used by more and more people.

It is worth mentioning that Unity can be used to create not only games but any kind of interactive app, from simple mobile apps to complex training or education applications (known as serious gaming), using the latest technologies, such as augmented and virtual reality. So, even if we are creating a game here, you are starting a learning path that can end in lots of possible specializations.
