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.

Generic methods

A standalone generic method needs to have a placeholder type parameter, just like a generic class, which allows it to be included inside either a generic or non-generic class as needed:

public void GenericMethod<T>(T genericParameter) {}

The T type can be used inside the method body and defined when the method is called:

GenericMethod<string>("Hello World!");

However, if you want to declare a generic method inside a generic class, you don't need to specify a new T type:

public class SomeGenericCollection<T> 
{
public void NonGenericMethod(T genericParameter) {}
}

When you call a non-generic method that uses a generic type parameter, there's no issue because the generic class has already taken care of assigning a concrete type:

SomeGenericCollection<int> highScores = new SomeGenericCollection
<int> ();
highScores.NonGenericMethod(35);
Generic methods can be...
