AI Assistant (beta) to help accelerate your learning

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

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.
