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

As with variables, method declarations have their basic requirements, which are as follows:

  • The type of data that will be returned by the method 
  • A unique name, starting with a capital letter
  • A pair of parentheses following the method name 
  • A pair of curly brackets marking the method body (where instructions are stored)

Putting all of these rules together, we get a simple method blueprint:

returnType UniqueName() 
{
method body
}

Let's break down the default Start() method in LearningCurve as a practical example:

In the preceding output, we can see the following:

  • The method starts with the void keyword, which is used as the method's return type if it doesn't return any data.
  • The method has a unique name.
  • The method has a pair of parentheses after its name to hold any potential parameters.
  • The method body is defined by a set of curly brackets.
In general, if you have a method that has an empty method body, it's good practice...
