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.

Writing C# statements properly


When you do normal writing, it's in the form of a sentence, with a period used to end the sentence. When you write a line of code, it's called a statement, with a semicolon used to end the statement.

Note

The reason a statement ends with a semicolon is so that Unity knows when the statement ends. A period can't be used because it is used in the dot syntax.

The code for a C# statement does not have to be on a single line as shown in the following example:

public int number1 = 2;

The statement can be on several lines. Whitespace and carriage returns are ignored, so, if you really want to, you can write it as follows:

public
int
number1
=
2;

However, I do not recommend writing your code like this because it's terrible to read code that is formatted like the preceding code. Nevertheless, there will be times when you'll have to write long statements—longer than one line. Unity won't care. It just needs to see the semicolon at the end.
