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.

Creating Shaders with Shader Graph

Now that we know how Shaders work and the existing Shaders in URP, we have a basic notion of when it is necessary to create a custom Shader and when it is not necessary. In case you really need to create one, this section will cover the basics of effects creation with Shader Graph, a tool to create effects using a visual node-based editor, being an easy tool to use when you are not used to coding.

In this section, we will discuss the following concepts of the Shader Graph:

  • Creating our first Shader Graph
  • Using Textures
  • Combining Textures
  • Applying Transparency

Let's start seeing how we can create and use a Shader Graph.

Creating our first Shader Graph asset

Shader Graph is a tool that allows us to create custom effects using a node-based system. An effect in Shader Graph can look like the following screenshot, where you can see the nodes needed to create a hologram effect:
