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.

Indexing and subscripts

Each array element is stored in the order it's assigned, which is referred to as its index. Arrays are zero-indexed, meaning that the element order starts at zero instead of one. Think of an element's index as its reference, or location. In topPlayerScores, the first integer, 452, is located at index 0, 713 at index 1, and 984 at index 2:

Individual values are located by their index using the subscript operator, which is a pair of square brackets that contains the index of the elements. For example, to retrieve and store the second array element in topPlayerScores, we would use the array name followed by subscript brackets and index 1:

// The value of score is set to 713
int score = topPlayerScores[1];

The subscript operator can also be used to directly modify an array value just like any other variable, or even passed around as an expression by itself:

topPlayerScores[1] = 1001;
Debug.Log(topPlayerScores[1]);

The values in topPlayerScores are...
