Okay thank you guys, that helped me

I guess now I'm even more confused. I tried using the basic class system I had from other lua scripts and it threw an error. Can you provide me with a very simple, cut and dry way to create a new class?

Hi, I'm pretty new here but I'm very familiar with lua. I do have a question about classes, though. I know how to create and use them, but the variable "__HAS_SECS_COMPATIBLE_CLASSES__" is confusing. Do I need to use this in every file I construct a class in or just once in my game?
