Okay, I wanna do something unique here and have a sneaky level. You start out with no weapon, and through positioning and cinematics (maybe), steal a weapon off someone helpless.

I want to start this off with a somewhat simple question. How can I make a grate that doesn't break, but instead swings downward once used? Do I use a func_rotating? Thanks for the help.

Nah. You use an entity and scripting. Possibly a func_static and scripting.

Here's a tutorial by some bloody n00b that you can apply with a little imagination. Be sure to skip the areaportaling part, for you don't want to combine a grate and an areaportal...

You use a black background with white lines? That would hurt my eyes after awhile.

I do. It's so much less blinding than a white background with black lines. That would be like staring into a lightbulb.

Thanks for the tut BTW. I'll try it out later.

The original JK2Radiant had the theme I'm still using even with GTK: Black background, dull green/gray grid lines, white lines for worldspawn. If I remember correctly, to get a perfect replication I had to hack some of it in by editing some file in Notepad...
