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.

foreach loops

foreach loops take each element in a collection and store it in a local variable, making it accessible inside the statement. The local variable type must match the collection element type to work properly. foreach loops can be used with arrays and lists, but they are especially useful with dictionaries, as they are not based on a numeric index.

In blueprint form, a foreach loop looks like this:

foreach(elementType localName in collectionVariable)
{
code block;
}

Let's stick with the questPartyMembers example and do a roll call for each of its elements:

List<string> questPartyMembers = new List<string>()
{ "Grim the Barbarian", "Merlin the Wise", "Sterling the Knight"};

foreach(string partyMember in questPartyMembers)
{
Debug.LogFormat("{0} - Here!", partyMember);
}

We can break this down as follows:

  • The element type is declared as a string, which matches the values in questPartyMembers.
  • A local variable, called...
