NPCs killing other NPCs in Plane of Growth.
 
Seems a bit random. Thought it might be faction, so I put them all on the same one. Thought it could possibly be a spell issue, but I'm not seeing and negative spells, just buffs. Also doesn't appear to be race or class related either. Open to any suggestions.

Thank you

Make sure you have not set the faction to attack other members of the same faction. In the 'npc_faction_entries' table, the 'npc_value' needs to not be -1 towards the same faction id.

Gregk 02-27-2013 06:32 PM
Double checked. Didn't seem to be it. I do appreciate the info, always good to pick up new info.

I noticed this same issue in BoT. I zoned in and once i walk up the double set of stairs I start seeing messages like "You will not evade me such-n-such". Obviously two giant factions fighting each other. I've never adjusted the table so I'm not sure why it's happening all the sudden.

Has anyone tried killing both sides of the melee to see what faction hits are actually occurring? (Or looked at the loaded value for each?)

Georges editor did this to my server, have you used it recently ?

trevius 02-28-2013 02:39 AM
Just a guess, but do either of the NPCs attacking (or being attacked) have the special attack code "U" set for unslowable? If so, and if they get buffed with haste, I think that will cause aggro based on the code I posted about in this thread about a similar issue:

I did use georges tools. I will also check faction hits a bit later. Off to fo the work thing...
Many thanks for the tips.

Now that you mention it, yes. But I only used it to remove spectral parchments from mobs that shouldn't be dropping it. Like frogs in Plane of Storm; perhaps the saves are editing mass tables because i have never edited BoT for loot.

I saw this in BoT the other day and I don't think it registered what was going on. I also saw the 'You will not evade me' . Trevius' explanation makes a lot of sense, since I spend a lot of time i BoT and hadn't seen it before. I use a stock peq db except for changes I make that I plan to commit.

Would the same thing happen if SoW was cast on a mob which was unsnarable? Because I have seen this in a few cases where mobs are not unslowable. Mastruqs in Qinimi, abandoned workers in the Sewers (okay, these are unslowable), Phara Dar attacking her guardians and a couple more places I think.

trevius 03-01-2013 06:18 AM
Yes, it appears so:

Code:
        if
(
IsEffectInSpell(spell_id, SE_Root) ||
IsEffectInSpell(spell_id, SE_MovementSpeed)
)
{
if(SpecAttacks[UNSNAREABLE]) {
mlog(SPELLS__RESISTS, "We are immune to Snare spells.");
caster->Message_StringID(MT_Shout, IMMUNE_MOVEMENT);
int32 aggro = CheckAggroAmount(spell_id);
if(aggro > 0) {
AddToHateList(caster, aggro);
} else {
AddToHateList(caster, 1);
}
return true;
}
}
I wouldn't be surprised if this same issue applies to other special attacks as well.

I think the easiest fix would be to add an IsDetrimentalSpell(spell_id) check in SpellOnTarget() before the IsImmuneToSpell() check here in spells.cpp:

Code:
        // check immunities
        if(spelltar->IsImmuneToSpell(spell_id, this))
        {
                //the above call does the message to the client if needed
                mlog(SPELLS__RESISTS, "Spell %d can't take hold due to immunity %s -> %s", spell_id, GetName(), spelltar->GetName());
                safe_delete(action_packet);
                return false;
        }
Maybe I am missing something though, but this is my best guess for the cause of the NPC vs NPC attacking issue.

Not really sure why this seems to be a new issue all of the sudden. I am not aware of any recent changes to how this works offhand, but I didn't really look into it much.

It is not new; it has been around for months. I first noticed it last november or so.

yes I did noticed that in SSRA where mobs were randomly attacking each other and I didn't know why. The npc aggro were set to 0 and were checked off in the editor. There was no reason why they should be attacking each other.

sorvani 03-02-2013 01:39 AM
I changed that to fix them not aggroing at all when they should.

Wish one of the people who noticed it months ago could have reported it then.

Simply need to add a check that the caster is a client or pet with client owner before assigning aggro

I did, but since I do not play on PEQ I reported it on the forum belonging to the server on which I play. It is not always easy to know what is a general issue and what is server only.

Is this getting fix soon?
