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.

Storing items in the List


Using a List instead of an array can be so much easier to work with in a script. Look at some forum sites related to C# and Unity, and you'll discover that a great deal of programmers simply don't use an array unless they have to; they prefer to use a list. It is up to the developer's preference and task. Let's stick to lists for now.

Here are the basics of why a List is better and easier to use than an array:

  • An array is of fixed size and unchangeable

  • The size of a List is adjustable

  • You can easily add and remove elements from a List

  • To mimic adding a new element to an array, we would need to create a whole new array with the desired number of elements and then copy the old elements

The first thing to understand is that a List has the ability to store any type of object, just like an array. Also, like an array, we must specify which type of object we want a particular List to store. This means that if you want a List of integers—of the int type—then you can create a...
