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.

What is a method?


When we write a script, we are making lines of code that the computer is going to execute, one line at a time. As we write our code, there will be things that we want our game to execute more than once. For example, we can write a piece of code that adds two numbers. Suppose our game needs to add those two numbers a hundred different times during gameplay. So you'd say, "Wow! I have to write the same code a hundred times to add two numbers together? There has to be a better way."

Let a method take away your typing pain. You just have to write the code to add two numbers once and then give this chunk of code a name, such as AddTwoNumbers(). Now, every time your game needs to add two numbers, don't write the code over and over; just call the AddTwoNumbers() method.

Using the term "method" instead of "function"

You are constantly going to see the words "function" and "method" used everywhere as you learn how to code.

Note

The words "function" and "method" truly mean the same thing...
