Group recall was created by JTP

Hey
Made a group recall spell, but it only works 100% if the caster is the leader, if someone else is the leader, then only caster and those listed above caster is recalled, leaving one or more people behind..

Ideas to solve this ?

My idea would be to iterate through all group members with the simple_list code kinda like this:

Code:

while ((k = (struct char_data *) simple_list(ch->group->members)) != NULL)
{
  < your code for recalling the player here >
}

My group recall just uses normal recall, with a mag_group define

Nice catch.

This happens because, once the caster leaves the room, the rest of the group is no longer with him. This is mag_groups ( github.com/tbamud/tbamud/blob/2f12752373...8a4/src/magic.c#L586 ):

(browser code, beware):

Code:

void mag_groups(int level, struct char_data *ch, int spellnum, int savetype)
{
  struct char_data *tch;

  if (ch == NULL)
    return;

  if (!GROUP(ch))
    return;
    
  while ((tch = (struct char_data *) simple_list(GROUP(ch)->members)) != NULL) {
    if (IN_ROOM(tch) != IN_ROOM(ch))
      continue;
+    if (tch == ch)
+      continue;
    perform_mag_groups(level, ch, tch, spellnum, savetype);
  }
+  perform_mag_groups(level, ch, ch, spellnum, savetype);
}

This function only performs the spell on group members in the same room as the caster. So if the caster recalls before all of the other group members, they get left behind. Not sure if removing that check will cause other group spells to act strangely, but that would be the easiest fix..

Code:

void mag_groups(int level, struct char_data *ch, int spellnum, int savetype)
{
  struct char_data *tch;

  if (ch == NULL)
    return;

  if (!GROUP(ch))
    return;
    
  while ((tch = (struct char_data *) simple_list(GROUP(ch)->members)) != NULL) {
>    if (IN_ROOM(tch) != IN_ROOM(ch))
>      continue;
    perform_mag_groups(level, ch, tch, spellnum, savetype);
  }
}
