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.

Time for action – choosing an action

That was a lot of new syntax and information, but it helps to see it in action. Let's create a simple switch statement for different actions a character could take:

  1. Create a new string variable (member or local), named characterAction, and set it to Attack.
  2. Declare a switch statement and use characterAction as the match expression.
  3. Create two case statements for Heal and Attack with different debug logs. Don't forget to include the break keyword at the end of each.
  4. Add a default case with a debug log and break.
  5. Save the file and click on Play in Unity:

Since characterAction is set to Attack, the switch statement executes the second case and prints out its debug log. Change characterAction to either Heal or an undefined action to see the first and default cases in action:

There are going to be times where you need several, but not all, switch cases to perform the same action. These are called fall-through cases...
