The problem with -any- code that involves setting different 'ratings' in different rooms is the fact that someone has to manually walk through the entire MOO, read the locations descriptions and assign the appropriate values.
There's several examples of values that should be set on various rooms that at the moment aren't fully set up through the entire MOO. TV's. At the moment you can see TV's in -almost- every room in the MOO, except those ones we've already decided to remove them from. Ambient population (the yellow 'people' messages you see on the streets.) is set up on all the streets, but alot of indoor public locations need setting up also, a process that would also involve setting up appropriate messages for each room.
Code is already in place to assign a room as unhidable in. Small and featureless rooms. Part of my recent movement recode involved fixing a loophole that allowed you to sneak -into- these rooms and be hidden.
What I've always planned to do, and still will, is to tweak stealth to be modded by ambient population. So, if you'll find it easier to hide in a location -full- of people and slightly harder to hide if you're pretty much alone in a location. This'll mostly apply to moving while hidden, since static hide just involves finding a spot and sitting in it.
Other than that, the last thing anyone has the time to be doing is walking round assigning a new value to every room in the MOO.
And incidentally… if you find a room you can hide in that you think you -shouldn't- be able to hide in, let us know.
The ability to sneak through doorways incredibly easily bothers me somewhat, being that the nature of a doorway restricts your stealthy movements to a focal point at which you'd be very noticable... but hacking that would pretty much render sneaking useless, so I doubt any changes will be made.
Stealth in general needs some tweaking. It's come to my attention that the awareness of people being sneaked passed is very hit an miss. Frequently, characters with very low awareness will have no problem spotting someone with a very high stealth, over and over. I'll be looking into that.
