A programming language such as C# can appear to be very complicated at first but in reality, there are two parts that form its foundation. These parts are variables and methods. Therefore, understanding these critical parts is a prerequisite for learning any of the other features of C#. Being as critical as they are, they are very simple concepts to understand. Using these variable and method foundation pieces, we'll be introduced to the C# building blocks used to create Unity scripts.
For those people who get sweaty palms just thinking of the word script, wipe your hands and relax. In this chapter, I'm going to use terms that are already familiar to you to introduce the building blocks of programming. The following are the concepts introduced in this chapter:
Let's have a look at these primary concepts.
You are constantly going to see the words function and method used everywhere as you learn Unity.
Since you are studying C#, and C# is an Object-Oriented Programming (OOP) language, I will use the word "method" throughout this book, just to be consistent with C# guidelines. It makes sense to learn the correct terminology for C#. Also, UnityScript and Boo are OOP languages. The authors of the Scripting Reference probably should have used the word method instead of function in all documentation.
