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.

Introducing stacks

At its most basic level, a stack is a collection of elements of the same specified type. The stack length is variable, meaning it can change depending on how many elements it's holding. The important difference between a stack and a list or array is how the elements are stored. Stacks follow the last-in-first-out (LIFO) model, meaning the last element in the stack is the first accessible element. This is useful when you want to access elements in reverse order. You should note that they can store null and duplicate values.

All the collection types in this chapter are a part of the System.Collections.Generic namespace, meaning you need to add the following code to the top of any file that you want to use them in:

using System.Collections.Generic;

Now that you know what you're about to work with, let's take a look at the basic syntax for declaring stacks.
