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.

Understanding Canvas and RectTransform

Currently, there are three UI systems available in Unity for different purposes:

  • UI Elements: A system to extend the Unity Editor with custom windows and tools. This uses several web concepts, such as stylesheets and XML-based language, to lay out your UI. In the future, it will be available to use in-game.
  • Unity UI: A GameObject-based UI only applicable for in-game UIs (not editor extensions). You create it using GameObjects and components like any other object we have edited so far.
  • IMGUI: A legacy code-based UI created entirely by using scripting. A long time ago, this was the only UI system used in both the editor and the in-game UI. Nowadays, it is only used to extend the editor and will soon be completely replaced by UI Elements.

In this chapter, we are only going to focus on in-game UI to communicate different information to the player regarding the state of the game, so we are going to use Unity UI. At the time...
