Learning C# by Developing Games with Unity 2019 - Fourth Edition

By: Harrison Ferrone

Overview of this book

Learning to program in today’s technical landscape can be a daunting task, especially when faced with the sheer number of languages you have to choose from. Luckily, Learning C# with Unity 2019 removes the guesswork and starts you off on the path to becoming a confident, and competent, programmer using game development with Unity. You’ll start off small by learning the building blocks of programming, from variables, methods, and conditional statements to classes and object-oriented systems. After you have the basics under your belt you’ll explore the Unity interface, creating C# scripts, and translating your newfound knowledge into simple game mechanics. Throughout this journey, you’ll get hands-on experience with programming best practices and macro-level topics such as manager classes and flexible application architecture. By the end of the book, you’ll be familiar with intermediate C# topics like generics, delegates, and events, setting you up to take on projects of your own.

Access modifiers

Now that the basic syntax is no longer a mystery, let's get into the finer details of variable statements. Since we read code from left to right, it makes sense to begin our variable deep-dive with a topic we haven't discussed yet: access modifiers.

Take a quick look back at the variables we used in LearningCurve and you'll see they had an extra keyword at the front of their statements:public. This is the variables access modifier. Think of it as a security setting, determining who and what can access the variable's information.

Any variable that isn't marked publicwon't show up in the Unity Inspector panel.

If you include a modifier, the updated syntax recipe looks like this:

accessModifier dataType uniqueName = value;

While access modifiers aren't necessary to declare a variable, it's a good habit to get into as a new programmer. That extra word goes a long way toward readability...
