Request/Question - always aggros npc

Forgive me if I am out of date on this but here is what I know:

Back when I was actively messing with the server, I learned that in order to make npc always aggro on a player regardless of a level (like lev 5 undead aggro on lev 50 players) you had to set their INT below 75. Which is a bit awkward and obscure and most people don't even know this. I know npc stats probably not used for much, but wouldn't it be better to change that and set it with proper npc Flag instead, like we do for Special Attacks? (http://wiki.eqemulator.org/p?NPC_Spe...tacks&frm=Main)

Thank You!

Could this ruletype help ?

Code:

RULE_INT(Aggro, IntAggroThreshold, 75) // Int <= this will aggro regardless of level difference.

Yeah, but I think its sort of weird assigning it to a stat score rather than having a special attack flag.

Yes, I agree with you. It is a weird way of doing it.

I experienced a brain fart initially. So the request is to make it a special attack. Hmm.

Exactly ;) Like the similar things here:
http://wiki.eqemulator.org/p?NPC_Spe...tacks&frm=Main

This is a pretty basic change guys.

You'll need to add the special ability. Here's an example:

Code:

common.h



        IGNORE_ROOT_AGGRO_RULES = 42,

        CASTING_RESIST_DIFF = 43,

        COUNTER_AVOID_DAMAGE = 44,

        PROX_AGGRO = 45,

        ALWAYS_AGGRO = 46, <-----

        MAX_SPECIAL_ATTACK = 47

Then, just add it in where it fits your goal. Such as:

Code:

aggro.cpp



Mob::CheckWillAggro



   ...



        if (RuleB(Aggro, UseLevelAggro) && ((

                ( GetLevel() >= 18 )

                ||(GetBodyType() == BT_Undead)

                ||( mob->IsClient() && mob->CastToClient()->IsSitting() )

                ||( mob->GetLevelCon(GetLevel()) != CON_GREEN )

                ||( GetSpecialAbility(ALWAYS_AGGRO) ))

After that, add the special ability to the NPC's that you desire. Voilà.

That function is so abhorrent it deserves an award.

How does this current rule fit into that ? Because I'm ok, with it so far.

Code:

RULE_BOOL(Aggro, UseLevelAggro, true) // Level 18+ and Undead will aggro regardless of level difference. (this will disable Rule:IntAggroThreshold if set to true)

you would have to have pretty low intelligence to attack a a lvl 50 at lvl 5. maybe that's the reasoning? =p

Thank You Coenxai!
Would be great our devs would add this to the official source! ;)

BTW the mob doesn't necessarily needs to be Undead ;)
It can be any type of mob that's needs to be always aggro ;)

It will aggro regardless of BodyType with the special ability. Undead will aggro regardless of special ability.

actually it would be better if Undead don't always aggro automatically - because you may want undead that don't aggro. (not all undead on live were always aggro - there was a number of undead in various places/levels that obeyed level difference green status)
So its better to have all mobs without default rules, and then apply the "always aggro" flag where actually needed.

I'm going to post slightly more readable aggro code.

I didn't test this properly but it should work.

Code:

aggro.cpp



bool Mob::CheckWillAggro(Mob *mob) {



        if(!mob)

                return false;



        if (mob->IsClient()) {

                if (!mob->CastToClient()->ClientFinishedLoading() || mob->CastToClient()->IsHoveringForRespawn() || mob->CastToClient()->zoning || !mob->CastToClient()->Connected() 

                        || mob->CastToClient()->GetGM() || mob->CastToClient()->IsLD() || mob->CastToClient()->IsBecomeNPC() || mob->IsInvisible(this))

                        return false;

        }



        Mob *ownr = mob->GetOwner();

        if (ownr && ownr->IsClient() && !ownr->CastToClient()->ClientFinishedLoading() || mob == ownr)

                return false;



        // Don't aggro new clients if we are already engaged unless PROX_AGGRO is set. WHY ARE WE CHECKING COMBAT AND AGGRO RANGE? THIS SHOULD BE COMBINED.

        if (IsEngaged() && !GetSpecialAbility(PROX_AGGRO) || GetSpecialAbility(PROX_AGGRO) && !CombatRange(mob)) {

                Log(Logs::Moderate, Logs::Aggro, "%s is in combat, and does not have prox_aggro, or does and is out of combat range with %s", GetName(), mob->GetName());

                return false;

        }



        float AggroRange, t1, t2, t3;



        AggroRange = GetAggroRange();

        t1 = mob->GetX() - GetX();

        t2 = mob->GetY() - GetY();

        t3 = mob->GetZ() - GetZ();



        if (t1 < 0)

                t1 = 0 - t1;

        if (t2 < 0)

                t2 = 0 - t2;

        if (t3 < 0)

                t3 = 0 - t3;



        if ((t1 > AggroRange) || (t2 > AggroRange) || (t3 > AggroRange))

                return false;



        float dist2 = DistanceSquared(mob->GetPosition(), m_Position);

        float AggroRange2 = AggroRange*AggroRange;



        if (dist2 > AggroRange2)

                return false;



        FACTION_VALUE fv = mob->GetReverseFactionCon(this);

        uint8 MyLevel = GetLevel();



        int heroicCHA_mod = mob->itembonuses.HeroicCHA/25; // 800 Heroic CHA cap

        if(heroicCHA_mod > THREATENLY_ARRGO_CHANCE)

                heroicCHA_mod = THREATENLY_ARRGO_CHANCE;



        if (MyLevel >= RuleI(Aggro, LevelAggro) || (GetBodyType() == BT_Undead && MyLevel >= RuleI(Aggro, UndeadLevelAggro)) || GetINT() <= RuleI(Aggro, IntAggroThreshold)

                || mob->IsClient() && mob->CastToClient()->IsSitting() || GetSpecialAbility(ALWAYS_AGGRO) || mob->GetLevelCon(GetLevel()) != CON_GREEN) {

                if (fv == FACTION_SCOWLS || fv == FACTION_THREATENLY && zone->random.Roll(THREATENLY_ARRGO_CHANCE - heroicCHA_mod) 

                        || (mob->GetPrimaryFaction() != GetPrimaryFaction() && mob->GetPrimaryFaction() == -4 && GetOwner() == nullptr)) {

                        if (CheckLosFN(mob)) {

                                Log(Logs::Detail, Logs::Aggro, "Check aggro for %s target %s.", GetName(), mob->GetName());

                                return(mod_will_aggro(mob, this));

                        }

                }

        }



        Log(Logs::Detail, Logs::Aggro, "InZone: %d | Dist^2: %f | Range^2: %f | Faction: %d | Con: %d | Int: %d | MyLevel: %d", mob->InZone(), dist2, AggroRange2, fv, GetINT(), GetLevelCon(mob->GetLevel()), MyLevel);



        return false;

}

        COUNTER_AVOID_DAMAGE = 44,

        PROX_AGGRO = 45,

        ALWAYS_AGGRO = 46, <---

I am not exactly sure what BT_Undead is? and how its different from just Undead?
