Well, all you really need to store is a single bit (1 or 0) for each
room. Since the higest possible zone is 326 you'd end up with something
like this...
unisgned long seen_rooms[1019]; /* 32600 / 32 rounded up */
Add that to struct player_special_data_saved and yes, it WILL mess up
your pfiles.
you can access it like so...
#define GET_SEEN_ROOM(ch,vnum) \
(CHECK_PLAYER_SPECIAL((ch),((ch)->player_specials->saved.seen_rooms)[(vnum)/32]&((vnum)%32))
#define SET_SEEN_ROOM(ch,vnum) \
(CHECK_PLAYER_SPECIAL((ch),((ch)->player_specials->saved.seen_rooms)[(vnum)/32]|=(1<<((vnum)%32)))
#define CLEAR_SEEN_ROOM(ch,vnum) \
(CHECK_PLAYER_SPECIAL((ch),((ch)->player_specials->saved.seen_rooms)[(vnum)/32]&=~(1<<((vnum)%32)))
/* and just in case you really want it (for completeness sake)... */
#define TOGGLE_SEEN_ROOM(ch,vnum) \
(CHECK_PLAYER_SPECIAL((ch),((ch)->player_specials->saved.seen_rooms)[(vnum)/32]^((vnum)%32))
After that you're looking at an increase in pfile size of about 4k per
player and the same for memory usage. So if you have approx. 1000
players in your pfile and approx 100 of them play at any given time then
you'd be looking at increasing the pfile size by approximately 4 megs
and your memory usage by approx. 400k, a lot, but do-able.
