Unity actually gives any class with the name GameManager a special gear icon. You cant just forgo the cool gear icon!
(Its not too terrible from an organizational standpoint because most of the scripts are attached to game objects. MonoBehavior is a component of GameObject. For instance, you’d never have player movement in the GameManager class, you would put it in the component class attached to the player character GameObject.)
Im think it was designed with a clock in mind. That’s why it starts with north at the 12:00 position and goes clockwise. I learned it as ‘Never Eat Soggy Waffles’ but I’m sure there are a bunch of these.
