I never asked. =S Anyways, does it only show the object/brush you point and and output it's statistics in console?
People ask all the time, so it's a general statement. And no, what it does is, we fire at two locations, and it prints to the console, two vectors, in the format of a cubeoid.
The custom created versions of the portal gun are crap. The only way to use a good portal gun is to run Portal and play on HL2 maps.
Actually, I saw a fairly good one that isn't an exact replica, but looks good. http://www.garrysmod.org/downloads/?a=view&id=16671 Made by manhails, haven't tried it yet, my Garry's Mod is a mess when it comes to addons.
No portal gun works anymore, and it doesn't really help the fact we're not even running the engine from portal. People are trying to recreate it at the moment, but it's a monumental task. Even Garry won't bother with it.
