After reading this, I did the same thing on a stock copy of pl11 because I thought it might be kind of funny to see in action... some problems; Aggressive mobs dont make any check to see if vict = ch when attacking (normally they wouldnt need to, but when they're attacking eachother, you probably want them to not attack themselves as well... its probably the root cause of the crashes). The mud crashes durring the helper part of mobact... I'm not sure, but I think its probably because the mob ends up assisting themselves fighting themselves, or it could be some madness where they're assisting themselves right after they've killed themselves or something similarly insane :) > a) Is there a better way of having fighting MOBs? Make more extensive checking to make sure everything is a-ok, checking that probably issnt needed at all under the current stock system, so issnt present in the code. Also, you might want to add some sanity to the whole scheme and make say, certain races attack other races and certain clans attack other clans... if just all aggr mobs are attacking other aggr mobs by the time any players arrive on the scene every place on the mud that loads a group of aggressives in one room will have just one surviving mob who is going to probably be pretty hurt from slugging it out with his "comrades". > b) Is there a way I can tell more about how/what more specifically is > going wrong that is causing it to crash?

Check out gdb... read the man pages for it extensively, its probably your second best friend after grep as far as implementor's tools go. -Sky ImpMUD - circle-coders.intserv.com (207.8.156.36) 9000 Exile - exile-rp.intserv.com (207.8.156.59) 4000 Angstland - angry.infowar.com (207.8.156.??) 4000
