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.

Time for action  setting up an inventory

Let's create a dictionary to store items that a character might carry:

  1. Declare a Dictionary with a key type of string and a value type of int, called itemInventory.
  2. Initialize it to new Dictionary<string, int>(), and add three key-value pairs of your choice. Make sure each element is in its pair of curly brackets.
  3. Add a debug log to print out the itemInventory.Count property so that we can see how items are stored.
  1. Save the file and Play:

Here, a new dictionary, called itemInventory, was created and initialized with three key-value pairs. We specified the keys as strings, with corresponding values as integers, and printed out how many elements itemInventory currently holds:

Like lists, we need to be able to do more than just print out the number of key-value pairs in a given dictionary. We'll explore adding, removing, and updating these values in the following section.
