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.

Defining methods

In the last chapter, we briefly touched on the role methods play in our programs, namely, that they store and execute instructions, just like variables store values. Now we need to understand the syntax of method declarations and how they drive action and behavior in our classes.

Basic syntax

As with variables, method declarations have their own basic requirements, which are as follows:

  • The type of data that will be returned by the method
  • A unique name starting with a capital letter
  • A pair of parentheses following the method name
  • A pair of curly brackets marking the method body (where instructions are stored)

Putting all of these rules together, we get a simple method blueprint:
