Sorry, I was reading this and got to thinking about the flag META_AGG that
is a part of Decadence (a derivitive of sillymud..), which is sort of what
you are talking about.., since players can morph into creatures, which are
considered NPCs.  I think, anyway.  I haven't looked at that part of the
code.  Anyhow, I decided that a MOB_NPC_AGGR is a good flag to put in.  So
I spent 5 minutes and did it.  I just can't test it yet, so the following
code is MAILER CODE.  Pardon any bugs, problems that may occur.  The
compiler on my system is down due to a hacker or something.., so until

In structs.h, under all the other MOB_ flags...
#define MOB_NPC_AGGR    (1 << 18)       (18 is next number on my rotation,
                                         whichever is next on yours)

In constants.c, under the list of MOB_ flags and how they will appear when
you stat a mob, add
between the last item and the "\n"

In mobact.c, where it has the comment /* Aggressive mobs */, switch the
aggr code with this:

      found = FALSE;
      for (vict = world[ch->in_room].people; vict && !found; vict = vict->next_in_room) {
        if (IS_NPC(vict) || !CAN_SEE(ch, vict) || PRF_FLAGGED(vict, PRF_NOHASSLE))
        if (MOB_FLAGGED(ch, MOB_WIMPY) && AWAKE(vict))
        if (!IS_NPC(vict))
          if (!MOB_FLAGGED(ch, MOB_AGGR_TO_ALIGN) ||
              (MOB_FLAGGED(ch, MOB_AGGR_EVIL) && IS_EVIL(vict)) ||
              (MOB_FLAGGED(ch, MOB_AGGR_NEUTRAL) && IS_NEUTRAL(vict)) ||
              (MOB_FLAGGED(ch, MOB_AGGR_GOOD) && IS_GOOD(vict))) {
            hit(ch, vict, TYPE_UNDEFINED);
            found = TRUE;
          if (MOB_FLAGGED(ch, MOB_NPC_AGGR)) {
            hit(ch, vict, TYPE_UNDEFINED);
            found = TRUE;

Again, this is mailer code.  If you see any bugs in it tell me, via
private or list mail, I don't care ;)  As long as it don't bug everyone

- The coder who is seldom motivated, but when is does quick work
