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.

Introducing enumerations 

By definition, an enumeration type is a set, or collection, of named constants that belong to the same variable. These are useful when you want a collection of different values, but with the added benefit of them all being of the same parent type.

It's easier to show rather than tell with enumerations, so let's take a look at their syntax in the following code snippet:

enum PlayerAction { Attack, Defend, Flee };

Let's break down how this works, as follows:

  • The enum keyword declares the type followed by the variable name.
  • The different values an enum can have are written inside curly brackets, separated by a comma (except for the last item).
  • The enum has to end with a semicolon, just like all other data types we've worked with.

To declare an enumeration variable, we use the following syntax:

PlayerAction currentAction = PlayerAction.Defend;

Again, we can break this down, as follows:

  • The type is set as PlayerAction.
  • The variable...
