If you're on a *nix system (i'll assume this since you're talking
of sending from different servers), the solution is pretty simple - use
the gdb program to examine your core file. It will tell you why the
crash was caused, which file caused it, which line, etc.
Specifically though, i'd say that the do_hit might be the wrong
function to put this check in..see, do_hit ...
void hit(struct char_data * ch, struct char_data * victim, int type)
Now, i'm not the best programmer in the world, but I really
_really_ recommend that you not change the argument that you've been
passed (ie, redefine victim to be a different one.)
You're almost sure to screw something up like that. On the other
hand though, there is an easy way to do it..
Make a function like 'check_for_resucer'....
struct_char data *check_for_rescuer(struct char_data *mob,
struct char_data *vict) {
struct char_data *k = 0;
/* if they're not grouped, they will not be saved..*/
if(!(vict->master || vict->followers)) {
return vict;
}
/* they're grouped, check for master first */
if(vict->master && (mob->in_room == vict->master->in_room) &&
GET_SKILL(vict->master,SKILL_GOOD_RESCUE) &&
CAN_SEE(vict->master,mob) &&
other stuff like is standing etc ...) {
/* might want to do a skill check here, instead of auto-allowing
this hit transfer */
return (vict->master);
}
/* else the master either doesn't exist, or doesn't do the skill */
for (k = vict->followers; k; k = k->next) {
if(k && (mob->in_room == k->in_room) && GET_SKILL(k,SKILL_GOOD_RESCUE) &&
CAN_SEE(k,mob) && other stuff like is standing etc ...) {
/* might want to do a skill check here, instead of auto-allowing
this hit transfer */
return (k);
}
}
/* no one with the skill found */
return vict;
}
A simple enough function - run it like this:
hit(ch, check_for_rescuer(ch,vict), TYPE_UNDEFINED);
In each case of the hit function in the aggro section of your
mobact.c. This is pretty simple actually, it will return either the
player if no one can save them, or the player they should hit if not. It
doesn't involve any extensive changes either, as the do_hit function
should take care of it...
