All it did was watch for outgoing movement request packets and respond to them with OKs. The server was still checking though. So if you tried to move somewhere you couldn't, your client would see the OK from UOE, then later see the "nope" from the server and you would rebound back to where you were, and you would often get your client's idea of your position desynced from the servers, which was the one that actually mattered. >You could dye items glitched out colors, because the server didn't check that you chose a valid color from the dialog Yes, there were many bugs. Large and complex software has bugs. That bug was fixed. Which demonstrates exactly my point, that you can in fact do everything server side. >You could reveal hidden people, because the server just tagged them with a "hidden" flag, instead of not sending their location at all. Which packet sets the "hidden" flag again? http://necrotoolz.sourceforge.net/kairpacketguide/ http://necrotoolz.sourceforge.net/kairpacketguide/

They fixed the hidden flag problem by just not sending the character; you used to be able to talk while hidden, and later talking would reveal you, because there wasn't a hidden mob to tie the text to. If I remember right there were actually two stages of the run hack in UO; in the first it was an advantage when the server itself was laggy and not just the client, later it was only an advantage for working around laggy connections and had severe rubberbanding and desyncing. And no, this can never be worked around solely on the server without resorting to something like OnLive. Another thing I didn't mention about UOE was it could make it always be daytime--how are you going to work around that on the server? As for which packet: http://necrotoolz.sourceforge.net/kairpacketguide/packet78.htm http://necrotoolz.sourceforge.net/kairpacketguide/packet78.h... which links to: http://necrotoolz.sourceforge.net/kairpacketguide/CS/mobilestatus.htm http://necrotoolz.sourceforge.net/kairpacketguide/CS/mobiles... Which has the status "hidden"
