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 Update function and UI values


There is one thing I want to mention here. As you must have noticed, we are updating all UI values in the Update function. As the Update function is called on every frame, we are wasting a lot of computation power there. This isn't the most efficient or correct way of assigning these values for every frame. Ideally, we change the text value only when we need to; for example, when the value actually changes. I decided to show you this way because it's definitely the simplest way. As this book is written for you, a beginner in programming, this way just works.
