Learning C# by Developing Games with Unity 5.x - Second Edition

Overview of this book

Unity is a cross-platform game engine that is used to develop 2D and 3D video games. Unity 5 is the latest version, released in March 2015, and adds a real-time global illumination to the games, and its powerful new features help to improve a game’s efficiency. This book will get you started with programming behaviors in C# so you can create 2D games in Unity. You will begin by installing Unity and learning about its features, followed by creating a C# script. We will then deal with topics such as unity scripting for you to understand how codes work so you can create and use C# variables and methods. Moving forward, you will find out how to create, store, and retrieve data from collection of objects. You will also develop an understanding of loops and their use, and you’ll perform object-oriented programming. This will help you to turn your idea into a ready-to-code project and set up a Unity project for production. Finally, you will discover how to create the GameManager class to manage the game play loop, generate game levels, and develop a simple UI for the game. By the end of this book, you will have mastered the art of applying C# in Unity.

Custom constructors


We saw how to create new instance of an object using the following syntax:

new ObjectType();

This way, you are calling the public implicit constructor. In simple words, the default constructor creates an instance without taking any parameters. All C# objects that are not using custom constructors will be using an implicit constructor.

Another great ability is to write your own constructors. Why? It will have you typing a lot of code, it's fun to use, and it makes code much easier to read.

Custom constructor should be written within the code block of the class. Have a look at the example first and then we'll go through the actual syntax. A custom public constructor for the Person could look like this:

As you can see, it's nothing scary. A custom constructor is a public method taking some parameters. The generic syntax for the public constructor will always start with the keyword public followed by a class name. Inside the brackets, we can write any parameters we wish.
