How to send a message to all online characters in their messagebox

[JayPee]

I noob in source editting but i just want to ask how to send a message to all online characters in their message box

example is: I request a trade... It will display a message to all online chars that "User A request a trade on User B". I think clif_displaymessage(sd->fd,target_sd->status.name) cant do that. I found this clif_GlobalMessage

Thanks in advance.

I think you could avoid a source edit (If you are running an SQL based server) just use a query to loop through all members, if they are online, it will message them.

*Note: In the query you can recall the characters ID, name etc for certain things like:

*message "<character name>","<message>";

or

*isloggedin(<account id>{,<char id>})

assuming you only had < 128 players online... there would be a little more factors in it that just that..

Well it would just loop back before the query, and update the same variable o.o

mmmhmmm and then of course you need a sleep2 1; in the event there is > ~650 players haha but who knows

Oh haha true true

I came up with this code, is this correct?:

trade.c

char output[200];

void trade_traderequest(struct map_session_data *sd, struct map_session_data *target_sd)
  int level;
  int targetLevel;

   level = pc_isGM(sd);
   targetLevel = pc_isGM(target_sd);

  if((level>=60) && (targetLevel<=20))
  {
        sprintf(output, msg_txt(904), sd->status.name, target_sd->status.name);
      clif_broadcast(&sd->bl, output, strlen(output) + 1, 0, ALL_CLIENT);
  }
}

msg_athena.conf

  904: %s request a trade to %s

There is a method called map_foreachpc which will loop through all online players and execute a given method.

map_foreachpc(clif_displaymessage(sd->fd, "TEXT"));
