I'm assuming this is for some kind of quest system. If you wish to keep
track for _every_ player if s/he has been in every room in the game, this
method is not good. To do this would mean needing a lot of storage space.

If you save it all into the pfiles, the full list will have to be in
memory whenever the player is logged on - with room_vnum typedefed to
sh_int, 1000 rooms fill up 4k of memory - per player.

I suggest you save a sorted list of room numbers. And I'd suggest you
use vnums and not rnums, since rnums can be changed if a new area is

You could add the list in char_data - probably in

room_vnum *rooms;            /* pointer to first element of room list */
int        num_rooms;        /* length of room list */

with an access macro like


A usable file format could be something like

Then a
  CREATE(ROOM_LIST(ch), int, ROOM_LLEN(ch));
will create the list, and make it the right length.

Have you thought of trying dg scripts ? They save 'player variables' which
can be used for a multitude of things. A quick glance at one of my var

solved_jester_quest_area_31 0 1
old_man_area_140 0 1
dwarf_gate_guard 0 4
preferred_meal 0 bread

The last line shows I've been talking to the gateguard a little while,
and his next response (or rather list of responses) should be number 4.
Of course this requires some in-game scripting.
