Learning C# by Developing Games with Unity 2020 - Fifth Edition

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 – capturing return values 

We're going to use both ways of capturing and using return variables with two simple debug logs:

  1. Create a new local variable of the int type, called nextSkillLevel, and assign it to the return value of the GenerateCharacter() method call we already have in place.
  2. Add two debug logs, with the first printing out nextSkillLevel and the second printing out a new calling method with argument values of your choice.
  3. Comment out the debug log inside GenerateCharacter() with two backslashes (//) to make the console output less cluttered.
  4. Save the file and hit Play in Unity:

To the compiler, nextSkillLevel and the GenerateCharacter() method caller represent the same information, namely an integer, which is why both logs show the number 37:

That was a lot to take in, especially given the exponential possibilities of methods with parameters and return values. However, we'll ease off the throttle here for a minute...
