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

Declaring an array is similar to other variable types we've worked with, but has a few modifications:

  • Array variables require a specified element type, a pair of square brackets, and a unique name.
  • The new keyword is used to create the array in memory, followed by the value type and another pair of square brackets.
  • The number of elements the array will store goes inside the second pair of square brackets.

In blueprint form, it looks like this:

elementType[] name = new elementType[numberOfElements];

Let's take an example where we need to store the top three high scores in our game:

int[] topPlayerScores = new int[3];

Broken down, topPlayerScores is an array of integers that will store three integer elements. Since we didn't add any initial values, each of the three values in topPlayerScores is 0.

You can assign values directly to an array when it's created by adding them inside a pair of curly brackets at the end of the variable declaration. C# has...
