If you are a Unity developer and you wish to learn how to write C# scripts and code by creating games, then this book is for you. What You Will Learn Understand the fundamentals of variables, methods, and code syntax in C# Get to know about techniques to turn your game idea into working project Use loops and collections efficiently in Unity to reduce the amount of code Develop a game using the object-oriented programming principles Generate infinite levels for your game Create and code a good-looking functional UI system for your game Publish and share your game with usersIn DetailUnity 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.

C# documentation -- where to find it? Do I need it at all? The Unity community -- asking others for help Working with C# script files Lots of files can create a mess. Why does my Project tab look different?Creating a C# script file Introducing the MonoDevelop code editor Syncing C# files between MonoDevelop and Unity Opening LearningScript in MonoDevelop The namespace -- highlighted in blue The class definition -- highlighted in green Watching for possible gotchas while creating script files in Unity Fixing synchronization if it isn't working properly Adding our script to GameObject Instance? What is it? Summary Chapter 2 : Introducing the Building Blocks for Unity Scripts Understanding what a variable is and what it does Naming a variable. A variable name is just a substitute for a valueCreating a variable and seeing how it works Declaration Assignment Click on Play! Changing variables Watching for a possible gotcha when using public variables What is a method? Using the term method instead of function -- Method names are substitutes, too Introducing the class Inheritance The Start(), Update(), and Awake() methods and the execution order Components that communicate using dot syntax What's with the dots? Making decisions in code Using the NOT operator to change the condition. Checking many conditions in an if statementUsing else if to make complex decisions Making decisions based on user input Paper and pencil are powerful tools Summary Chapter 3 : Getting into the Details of Variables Writing C# statements properly Understanding component properties in Unity's Inspector Variables become component properties Unity changes script and variable names slightly Changing a property's value in the Inspector panel Displaying public variables in the Inspector panel Private variables Naming your variables properly Beginning variable names with lowercase. Using multiword variable namesDeclaring a variable and its type The most common built-in variable types Assigning values while declaring a variable Where you declare a variable is important Variable scope -- determining where a variable can be used Summary Chapter 4 : Getting into the Details of Methods Using methods in a script Naming methods properly Beginning method names with an uppercase letter Using multiword names for a method Parentheses are part of the method's name Defining a method the right way The minimum requirements for defining a method. Understanding parentheses -- why are they there?
