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

A list-type variable needs to meet the following requirements:

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

In blueprint form, it reads as follows:

List<elementType> name = new List<elementType>();
List length can always be modified, so there is no need to specify how many elements it will eventually hold when created.

Like arrays, lists can be initialized in the variable declaration by adding element values inside a pair of curly brackets:

List<elementType> name = new List<elementType>() { value1, value2 };

Elements are stored in the order they are added, are zero-indexed, and can be accessed using the subscript operator. Let's start setting up a list of our own to test out the basic functionality this class has on offer.
