Hi ArcadiaDivine,
If you open up system.vc in a text editor like Notepad, Textpad or Programmer's Notepad, you will see that this message is by design. It's meant to be a placeholder script until you put in your own code. You need to eventually change this to put in your game's system code.
So congratulations! And indeed, there was some mention of
looking at demos, reading
the new user section, and
the docs and so forth in that message. Please look into those, I think it will help you out a ton.
If you still have questions after reading through some of the documentation, I and others around the site can probably help you out.
