If a static var is declared inside a function, as you say it means its value will remain constant between calls to that function. The addenum is that when a static var is delared globally, meaing _not_ inside any funcion itself, it means that that variable cannot be accessed in any other c files VIA the 'extern' keyword. Its _scope_ is local to that C file, and that C file alone OBCircle: Here's something that may be of interest in those playing with that path thing for mobs to get about. Its an IMM only command I coded to show you directions to a room from your present location. Can be modified easy enough to get a list of numbers for perform_move. I use this when in a good mood and want to answer that age old GOSS, how do i get to Area_X from Room_B ACMD(do_path) { int dir, done = FALSE; room_num sroom, troom, temp_room; if (GET_LEVEL(ch) < LVL_IMMORT) { send_to_char("You have no idea how.\r\n", ch); return; } sroom = IN_ROOM(ch); one_argument(argument, arg); if (!*arg) { send_to_char("Where are you trying to find a path to?\r\n", ch); return; } if (!(troom = real_room(atoi(arg)))) { send_to_char("No-such target room.\r\n", ch); return; } temp_room = IN_ROOM(ch); do { done = FALSE; dir = find_first_step(sroom, troom); switch (dir) { case BFS_ERROR: send_to_char("[ERR]", ch); done = TRUE; break; case BFS_ALREADY_THERE: done = TRUE; break; case BFS_NO_PATH: send_to_char("[ERR]",ch); done = TRUE; break; default: sprintf(buf, "%s ", dirs[dir]); send_to_char(buf, ch); done = FALSE; break; } if (!done && EXITN(temp_room, dir)->to_room != NOWHERE) { sroom = EXITN(temp_room, dir)->to_room; temp_room = sroom; } } while (!done); send_to_char("\r\n",ch); } ******************************************************************* * Ron Hensley ron@dmv.com * * Network Administrator http://www.dmv.com/~ron * * PGP Key at WWW Page * * DelMarVa OnLine 749-7898 Ext. 403 * ******************************************************************* +------------------------------------------------------------+ | Ensure that you have read the CircleMUD Mailing List FAQ: | | http://democracy.queensu.ca/~fletcher/Circle/list-faq.html | +------------------------------------------------------------+
