Clan Code.  Mmmmm. [by Mehdi Keddache]

From: Mehdi Keddache <kam@shallot.salad.mssm.edu>
Subject: [Circle] Code for a clan system

Hello, this the clan code we use at Eclipse of Fate.

First I would like to thank all the CircleMUD coders for sharing
their talents and ideas with the rest of the CircleMUD community
and distributng their code as much as they do. I believe there is
nothing more rewarding than to see your code on someone else's
MUD and I am very happy to send the following system to the list
subscribers.

In this system immorts cannot join clans since we believe that clans
should really be a mortal thing. After imms create the clan, the clan
leaders are free to rule the clan as they wish, giving privileges
and changing the number of ranks in the clan.

Some features have not been implemented yet (like clan spells, and
clan wars) and the messages after you type the commands could really
use some revamping (like naming who you talk about or which clan).
There is a feature that doesn't work because I am still in the
process of fixing it: clan plan, there is some nasty str_dup that is
missing somwhere, i am just getting familiar with getting input from
the editor.

NOTES:
About the change in the number of ranks:
-The code acts on the whole player database each time this is done in
order to rerank all the off line clan members.
-For this reason i recommend setting the fee for such action pretty
high so that the system does lag every time a leader changes his mind
on how to set the hierarchy in his clan (it doesn't happen when they
can't afford it).

Email if you have any questions: kam@shallot.salad.mssm.edu

Feel free to distribute this code, it would be cool if you could just
give credit to the admin team of Eclipse of Fate (eclipse.argy.com 7777)
for the design and to me (Mehdi Keddache aka Heritsun) for the coding.


Hope you enjoy it...
      ...and most of all I hope it works for you as well as it does for us

Please inform me if you plan to use the code and maybe you can send me
your additions to it.


In the following I might have forgotten some #include "clan.h" or some
function prototypes, sorry...
Don't hesitate to let me know if something is missing, like a function
or whatever I could not remember to put in.


******in db.h*****
+ #define CLAN_FILE "etc/clans"


******in db.c*****

+ log("Booting clans.");
+ init_clans();

  boot_time = time(0);

  log("Boot db -- DONE.");



also add the function in the end:

void save_char_file_u(struct char_file_u st)
{
int player_i;
int find_name(char *name);

if((player_i = find_name(st.name)) >=0 )
  {
  fseek(player_fl, player_i * sizeof(struct char_file_u), SEEK_SET);
  fwrite(&st, sizeof(struct char_file_u), 1, player_fl);
  }
}

*****in Makefile*****
add to the OBJFILES

and the dependences:

$(CC) -c $(CFLAGS) clan.c

Also, add clan.h to the end of the dependencies for act.comm.o and
act.info.o

*****in structs.h*****

use one of the spare ubyte in the structure player_special_data_saved
for clan_rank and one of the spare int for clan
(see utils.h)


******
Finally the is_playing function it can go anywhere, ensure you
prototype it in files where you need to use it:

struct char_data *is_playing(char *vict_name)
{
  extern struct descriptor_data *descriptor_list;
  struct descriptor_data *i, *next_i;

  for (i = descriptor_list; i; i = next_i) {
    next_i = i->next;
    if(i->connected == CON_PLAYING && !strcmp(i->character->player.name,CAP(vic
t_name)))
      return i->character;
  }
  return NULL;
}



OTHER STUFF:
I will not be responsible if anything happens if you install this code
anywhere, use it at your own risks.
