Learning C# by Developing Games with Unity 2020 - Fifth Edition

By: Harrison Ferrone

Overview of this book

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.

Basic syntax

Structs are declared in the same way as classes, and can hold fields, methods, and constructors:

accessModifier struct UniqueName 

Like classes, any variables and methods belong exclusively to the struct and are accessed by its unique name.

However, structs have a few limitations:

  • Variables cannot be initialized with values inside the struct declaration unless they're marked with the static or const modifier—you can read more about this in Chapter 10, Revisiting Types, Methods, and Classes.
  • Constructors without parameters aren't permitted.
  • Structs come with a default constructor that will automatically set all variables to their default values according to their type. 

Every character requires a good weapon, and these weapons are the perfect fit for a struct object over a class. We'll discuss why that is in the Understanding reference and value types section of this chapter. However, first...
