Yep, it's in there! I recommend reading through the WHOLE thing as well, it is incredibly useful. Nickydude (the FPSC moderator who put together the community guide) has also created an extension to the guide, for v1.18. Covers the GUI-X9 commands, Dark AI, as well as more level design tips and ways to save FPSC resources and increase framerate! It's somewhere on his website. If I find the link, I'll come back here and post it for you.
Good luck with your game,

@Exu Corporations:
Hey, I saw you posted a fairwell thread, and was sad to see you leave. Did you decide to come back?
One of the most humbling days in your life will be the day you discover you AREN'T the best at what you do.
