Learning C# by Developing Games with Unity 3D Beginner's Guide

Overview of this book

For the absolute beginner to any concept of programming, writing a script can appear to be an impossible hurdle to overcome. The truth is, there are only three simple concepts to understand: 1) having some type of information; 2) using the information; and 3) communicating the information. Each of these concepts is very simple and extremely important. These three concepts are combined to access the feature set provided by Unity. "Learning C# by Developing Games with Unity 3D Beginner's Guide" assumes that you know nothing about programming concepts. First you will learn the absolute basics of programming using everyday examples that you already know. As you progress through the book, you will find that C# is not a foreign language after all, because you already know the words. With a few keywords and using substitution, before you know it, you'll be thinking in code. The book starts by explaining in simple terms the three concepts you need for writing C# code and scripts: 1) variables to hold information; 2) methods (functions) to use the information; and 3) Dot Syntax to communicate the information where it's needed. The book builds on these concepts to open up the world of C# coding and Unity scripting. You will use this new power to access the features provided in Unity's Scripting Reference. The first half of this book is devoted to the code writing beginner. The concepts of variables, methods, Dot Syntax, and decision processing are fully explained. Since C# is an actual programming language, we take advantage of this to develop a State Machine to help control and organize each phase of a Unity project. Once the basic programming concepts are established and we have some State Machine organization, the features and power of Unity are accessed using the Scripting Reference. If you're looking to learn C# for Unity then this is the book that offers everything you need and more - so discover what C# offers today and see your work come to life as complete games!

Scratching the surface of C# programming


We learned many ways to work with data. The code inside a method is where all the work is performed on the data, such as using the data to make decisions or modifying the data value. Even when Dot Syntax extracted data from another objects, all the work was performed in a method.

The C# code we used was rather basic, but we accomplished everything needed to create our game. Once again, that was the purpose of this book, to teach you the fundamental concepts of programming and use basic C# coding techniques to get the job done.

There are more C# techniques we could have used to make our code more efficient, and you may want to learn more about C#. But if you just want to understand enough C# to get some scripts written that are basic and easy to understand, then that's fine.

Understanding concepts can take a while to sink in before the lights turn on. So keeping the learning list short is important for a beginning programmer. This allows the basic concepts...
