Classes and Components #

Classes are the fundamental building blocks of programming. A class allows us to create instances of the class, called objects, which we … do everything with.

Oddly enough, in Unity programming, we don’t use classes that often. This is a lie. We use them in every single script we right, but we let Unity handle the creation and destruction of our classes for us. This is because most of our classes will be a unity component.

A basic Unity Script has the following line of code.

public class AgentMovement : MonoBehaviour
{
    //everything goes in here
}

When we create a component, we are creating a public class that extends “MonoBehaviour”. We will learn more about extending classes and creating our own special classes in the future. Let’s focus on components for now.
