Order in ADD_FOLLOWER was created by kogan

Hi,
anyone can help me to order followers in ADD_FOLLOWERS to follow squence and not to reverse?
Currently last followed enters always first now.

I tried to change it but got stuck here. Only the last 2 follow now :-(

void add_follower(struct char_data *ch, struct char_data *leader)
{
struct follow_type *k, *j;
struct char_data *l = leader;

if (ch->master) {
    core_dump();
    return;
}

ch->master = leader;

CREATE(k, struct follow_type, 1);

if (!l->followers) {
    k->follower = ch;
    k->next = NULL;
    leader->followers = k;
} else {
    while (l->followers->next) {
      l->followers = l->followers->next;
    }
    k->follower = ch;
    k->next = l->followers->next;
    leader->followers->next = k;
}

act("You now follow $N.", FALSE, ch, 0, leader, TO_CHAR);
if (CAN_SEE(leader, ch))
    act("$n starts following you.", TRUE, ch, 0, leader, TO_VICT);
act("$n starts to follow $N.", TRUE, ch, 0, leader, TO_NOTVICT);
}

Thanks for your assistane.

I suggest you surround your code with [ code] tags - it makes it easier to read.

Here's an attempt at browser code for helping you out:

void add_follower(struct char_data *ch, struct char_data *leader)
{
  struct follow_type *k, *j;
  struct char_data *l = leader;

  if (ch->master) {
    core_dump();
    return;
  }

  ch->master = leader;

  CREATE(k, struct follow_type, 1);
  k->follower = ch;
  k->next = NULL;

  if (!l->followers) {
    leader->followers = k;
  } else {
    j = l->followers;
    while (j->next) {
      j = j->next;
    }
    j->next = k;
  }

  act("You now follow $N.", FALSE, ch, 0, leader, TO_CHAR);
  if (CAN_SEE(leader, ch))
    act("$n starts following you.", TRUE, ch, 0, leader, TO_VICT);
  act("$n starts to follow $N.", TRUE, ch, 0, leader, TO_NOTVICT);
}

I did this inside of handler.c - I made a change to char_from_room()

void char_from_room(struct char_data *ch)
{
  struct char_data *temp, *i;

  if (ch == NULL || !VALID_ROOM_RNUM(IN_ROOM(ch))) {
    log("SYSERR: Extracting char from room NOWHERE. (char_from_room)");
    exit(1);
  }

  if (GET_EQ(ch, WEAR_LIGHT))
    if (GET_OBJ_TYPE(GET_EQ(ch, WEAR_LIGHT)) == ITEM_LIGHT)
      if (GET_OBJ_VAL(GET_EQ(ch, WEAR_LIGHT), 2)) /* Light is ON */
        world[IN_ROOM(ch)].light--; 

  if (ch == world[IN_ROOM(ch)].people) {
    world[IN_ROOM(ch)].people = ch->next_in_room;
  
  } else {
    if (world[IN_ROOM(ch)].people) {
      for (i = world[IN_ROOM(ch)].people; i != NULL && i->next_in_room != ch ; i = i->next_in_room)
       ; // KEEP THIS OR LOOP away! it will crash the game without it going into a loop- AP
        if (i != NULL)
          i->next_in_room = ch->next_in_room;
    }
  }

  if (FIGHTING(ch)) {
   if (FIGHTING(FIGHTING(ch)) == ch)
     stop_fighting(FIGHTING(ch));
   stop_fighting(ch);
  }

  REMOVE_FROM_LIST(ch, world[IN_ROOM(ch)].people, next_in_room);
  IN_ROOM(ch) = NOWHERE;
  ch->next_in_room = NULL;

}
