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.

Encapsulation

One of the best things about OOP is that it supports encapsulation—defining how accessible an object's variables and methods are to outside code (this is sometimes referred to as calling code). Take our soda can as an example—in a vending machine, the possible interactions are limited. Since the machine is locked, not just anyone can come up and grab one; if you happen to have the right change, you'll be allowed provisional access to it, but in a specified quantity. If the machine itself is locked inside a room, only someone with the door key will even know the soda can exists. 

The question you're asking yourself now is, how do we set these limitations? The simple answer is that we've been using encapsulation this entire time by specifying access modifiers for our object variables and methods. If you need a refresher, go back and visit the Access modifiers section in Chapter 3, Diving into Variables, Types, and Methods...
