Learning C# by Developing Games with Unity 2020

The Building Blocks of Programming

Any programming language starts off looking like ancient Greek to the unaccustomed eye, and C# is no exception. The good news is that underneath the initial mystery, all programming languages are made up of the same essential building blocks. Variables, methods, and classes (or objects) make up the DNA of conventional programming; understanding these simple concepts opens up an entire world of diverse and complex applications. After all, there are only four different DNA nucleobases in every person on earth; yet, here we are, unique organisms to the last.

If you're new to programming, there's going to be a lot of information coming at you in this chapter, and this could mark the first lines of code that you've ever written. The point is not to overload your brain with facts and figures; it's to give you a holistic look at the building blocks of programming using examples from everyday life.

This chapter is all about the high-level view of the bits and pieces that make up a program. Getting the hang of how things work before getting into the code directly will not only help you new coders find your feet, it will also solidify the topics with easy-to-remember references. Ramblings aside, we'll focus on the following topics throughout this chapter:

  • Defining what variables are and how to use them
  • Understanding the purpose of methods
  • Classes and their role as objects
  • Turning C# scripts into Unity components
  • Component communication and dot notation

Defining variables

Let's start with a simple question: what is a variable? Depending on your point of view, there are a few different ways of answering that question:

  • Conceptually, a variable is the most basic unit of programming, as an atom is to the physical world (excepting string theory). Everything starts with variables, and programs can't exist without them.
  • Technically, a variable is a tiny section of your computer's memory that holds an assigned value. Every variable keeps track of where its information is stored (this is called a memory address), its value, and its type (for instance, numbers, words, or lists). 
  • Practically, a variable is a container. You can create new ones at will, fill them with stuff, move them around, change what they're holding, and reference them as needed. They can even be empty and still be useful.

A practical real-life example of a variable is a mailbox; remember those?

They can hold letters, bills, a picture from your aunt Mabel – anything. The point is that what's in a mailbox can vary: they can have names, hold information (physical mail), and their contents can even be changed if you have the right security clearance.

Names are important

Referring to the preceding photo, if I asked you to go over and open the mailbox, the first thing you'd probably ask is: which one? If I said the Smith family mailbox, or the brown mailbox, or the round mailbox, then you'd have the necessary context to open the mailbox I was referencing. Similarly, when you are creating variables, you have to give them unique names that you can reference later. We'll get into the specifics of proper formatting and descriptive naming in Chapter 3, Diving into Variables, Types, and Methods.

Key benefits

  • Understand C# programming basics, terminology, and coding best practices
  • Put your knowledge of C# concepts into practice by building a fun and playable game
  • Come away with a clear direction for taking your C# programming and Unity game development skills to the next level

Description

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.

Who is this book for?

If you’re a developer, programmer, hobbyist, or anyone who wants to get started with C# programming in a fun and engaging manner, this book is for you. Prior experience in programming or Unity is not required.

What you will learn

  • Discover easy-to-follow steps and examples for learning C# programming fundamentals
  • Get to grips with creating and implementing scripts in Unity
  • Create basic game mechanics such as player controllers and shooting projectiles using C#
  • Understand the concepts of interfaces and abstract classes
  • Leverage the power of the latest C# features to solve complex programming problems
  • Become familiar with stacks, queues, exceptions, error handling, and other core C# concepts
  • Explore the basics of artificial intelligence (AI) for games and implement them to control enemy behavior

What a fun way to learn Unity and C#! I liked this book so much I included it in my list of the Ten Best Books for New Programmers in 2020-- But you don't have to be a new programmer to enjoy this book. If you're a current developer wanting to learn C# and/or Unity, I think Harrison's book will do the trick.This book manages to "thread the needle" well when giving strong coverage to the Unity environment and a comprehensive introduction to C#. The book clearly explains both fundamental topics like variables, but, doesn't shy away from the more complex topics, like C# generics. The author has a knack for good, clear explanations.This book should be on your shelf if you have any interest in C# or Unity! One of my favorites!

I really love this book. It goes into so much detail and explains every little aspect of C#. This is the book that I wish I had access to when I first started learning to code in Unity. It even gave me a better understanding of some of the things that I previously thought I understood. I even introduce me to a few simple things that I previously wasn't using like interpolated strings. I would highly recommend this book to any new developer learning to code in C#.
