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.

Basic syntax

A queue variable declaration needs to meet the following requirements:

  • The Queue keyword, its element type between left and right arrow characters, and a unique name
  • The new keyword to initialize the queue in memory, followed by the Queue keyword and element type between arrow characters
  • A pair of parentheses capped off by a semicolon

In blueprint form, a queue looks as follows:

Queue<elementType> name = new Queue<elementType>();
C# supports a non-generic version of the Queue type that doesn't require you to define the type of element it stores:

Queue myQueue = new Queue();

However, this is less safe and more costly than using the preceding generic version. You can read more about Microsoft's recommendation at
