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.

Variable syntax

We've seen how variables are created, and touched on the high-level functionality that they provide, but we're still missing the syntax that makes all of that possible. Variables don't just appear at the top of a C# script; they have to be declared according to certain rules and requirements. At its most basic level, a variable statement needs to satisfy the following requirements:

  • The type of data the variable will store needs to be specified
  • The variable has to have a unique name
  • If there is an assigned value, it must match the specified type
  • The variable declaration needs to end with a semicolon
