what about checking if a shopkeeper is in room first - something like
following:
shop_keeper = NULL;
for (tch = world[ch->in_room].people; tch; tch = next_tch) {
next_tch = tch->next_in_room;
if (IS_NPC(tch))
if (!MOB_FLAGGED(tch, MOB_SHOPKEEPER)) {
shop_keeper = tch;
break;
}
}
if (!shop_keeper) {
send_to_char("You can't do that here!\r\n", ch);
return;
}
..[now do your shopkeeper-code]...
