Introducing the class

The class plays a major role in Unity. In fact, what Unity does with a class a little piece of magic when Unity creates Components.

You just learned about variables and methods. These two items are the building blocks used to build Unity scripts. The term script is used everywhere in discussions and documents. Look it up in the dictionary and it can be generally described as written text. Sure enough, that's what we have. However, since we aren't just writing a screenplay or passing a note to someone, we need to learn the actual terms used in programming.

Unity calls the code it creates a C# script. However, people like me have to teach you some basic programming skills and tell you that a script is really a class.

In Chapter 7, Creating the Gameplay is Just a Part of the Game, we will be creating some classes for a State Machine. These classes will not be attached to any GameObjects, so I won't be calling them scripts.
