I mean with multiple links, so that it can curve. If you attached solid pieces to it, could an actor walk on it?

Somewhat, and no.
A "chain" could be made, as Abdul has done (I think it was him), with Lua, but it's not very stable and is reasonably laggy.
Actors would not be able to walk on it unless you made it out of door pieces, and even then I doubt it would be movable. Thus, not possible in it's entirety.

I wish there weren't as many limitations in CC's engine... Oh well; we're blessed to have CC itself. I'm brainstorming ideas for parts of the mission I'm making right now.

While I'm at it, how can I use that tutorial screen font? I have a tutorial sign for my mission but I need to use the font used in the original tutorial for the text...

You can't, unfortunately - it's hardcoded.

But in Exodus there's screens with text that's in the same font... Akakabla found the font somehow.

The image files are available; you can duplicate the appearance, but there's no way to do it in engine.

Well, okay, there is one way, but it isn't easy.
You'll find the font somewhere in the Base.rte/GUI folder. You then need to piece it together in an animation manually, and get it to animate properly.

Thanks guys! I came up with an idea a few minutes ago: Since the console has the same font as the tutorial, I can type stuff into the console, take a screenshot, then just crop it, replace the brown with pink, etc. And you have the image you need!

Just turn the screen into an animated bunker attachable that doesn't hit or get hit by MOs.

Looking forward to your mission Awsomeness.
