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.

Specifying return values

Aside from accepting parameters, methods can return values of any C# type. All of our previous examples have used the void type, which doesn't return anything, but being able to write instructions and pass back computed results is where methods shine. 

According to our blueprints, method return types are specified after the access modifier. In addition to the type, the method needs to contain the return keyword, followed by the return value. A return value can be a variable, a literal value, or even an expression, as long as it matches the declared return type.

Methods that have a return type of void can still use the return keyword with no value or expression assigned. Once the line with the return keyword is reached, the method will stop executing. This is useful in cases where you want to avoid certain behaviors or guard against program crashes.

Let's add a return type to GenerateCharacter() and learn how to capture it in a variable.
