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.

The for loop


You have learned about foreach loops. When iterating through a foreach loop, we can use a local variable directly to access the data we need. In a for loop, we also create a variable. However it is an integer variable for controlling the execution of the loop and accessing the data inside the collection by index.

There are three fundamental parts of the for loop. It will look a bit scary to you at the beginning, but try not to run away.

The for loop's syntax might look overcomplicated, but trust me, it isn't! Let's go through all of its elements one by one.

The for loop begins with the for keyword, followed by brackets. Inside the brackets we must have three fundamental elements separated by semicolons:

  • Initializer: The initializer is simply a declared variable that is assigned a value. In the preceding code, we declared a variable called i of the int type and assigned it a value of 0.

  • Condition: The condition must be true for the code block to be executed. In this example, the...
