Swinging Doors

Does anyone here know how to do a swinging door? I've seen done in various levels and megawads, though I can't figure out how to do myself. Any help would be appreciated :)

Dude - go online at around 8-10 pm tomorrow and I'll give you my own tutorial.

God forbid we actually poke around the website...

Since you had some questions about ZDoom before, I guess you want to use poly-objects for swinging doors (why not specify the port you want to edit for next time? ;): clicky clicky
