Hidden items and search skill
From: Whiplash <whiplash@tft.nacs.net>
Subject: Hidden items/Search skill
Here's a bit of code I threw together that implements hidden items in your
MUD, this is different than invis items, in that a player can HIDE an item,
and then another player can SEARCH for it, to reveal it. We use SEARCH as a
skill, and our skill_table stuff is hella different from Merc/ROM, so I
haven't included it here, but it's better that you decide what classes, and
levels you want this skill to affect anyway, other than that, everything
should be included here. If you use OLC, you'll wana add support for the
ITEM_HIDDEN bit in bit.c
Oh yeah, I don't require any credit for this..
but you can't take any either :)
Note -- Original code allowed players to hide cursed or nodrop noremove
items. This fixes that problem -- Leviticus
