By: Harrison Ferrone

Overview of this book

Over the years, the Learning C# by Developing Games with Unity series has established itself as a popular choice for getting up to speed with C#, a powerful and versatile programming language that can be applied in a wide array of application areas. This book presents a clear path for learning C# programming from the ground up without complex jargon or unclear programming logic, all while building a simple game with Unity. This fifth edition has been updated to introduce modern C# features with the latest version of the Unity game engine, and a new chapter has been added on intermediate collection types. Starting with the basics of software programming and the C# language, you’ll learn the core concepts of programming in C#, including variables, classes, and object-oriented programming. Once you’ve got to grips with C# programming, you’ll enter the world of Unity game development and discover how you can create C# scripts for simple game mechanics. Throughout the book, you’ll gain hands-on experience with programming best practices to help you take your Unity and C# skills to the next level. By the end of this book, you’ll be able to leverage the C# language to build your own real-world Unity game development projects.

Graphical UI

UIs are the visual components of any computer system. The mouse cursor, folder icons, and programs on your laptop are all UI elements. For our game, we want a simple display to let our players know how many items they've collected, their current health, and a textbox to give them updates when certain events happen.

UI elements in Unity can be added in the following two ways:

  • Directly from the Create menu in the Hierarchy panel, just as with any other GameObject
  • Using the built-in GUI class in code

We want to stick to the code version for this project and add in our three UI elements in the GameBehavior class. This isn't to say that one approach is better than the other, but since we are learning to program, it's a good idea to stay consistent.

The GUI class provides several methods to create and position components; all GUI method calls go in a MonoBehaviour method called OnGUI(). Think of OnGUI() as the Update() method for all things UI; it runs anywhere...
