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 – changing a variable's value

Since currentAge was declared as a variable on line 7, the value it stores can be changed. The updated value will then trickle down to wherever the variable is used in code; let's see this in action:

  1. Stop the game by clicking the Play button if the scene is still running.
  2. Change Current Age to 18 in the Inspector panel and play the scene again, looking at the new output in the Console panel:

The first output will still be 31, but the second output is now 19 because we changed the value of our variable. 

The goal here wasn't to go over variable syntax but to show how variables act as containers that can be created once and referenced elsewhere. We'll go into more detail in Chapter 3, Diving into Variables, Types, and Methods.

Now that we know how to create variables in C# and assign them values, we're ready to dive into the next important programming building block: methods!
