    Attacking Pets System

    in Features & Metin2 Systems

    Posted · Edited by Metin2 Dev
    Core X - External 2 Internal

    Corrected tabulation, code, include and english How-To :D


     

    [HowTo]
     
    Search in petsystem.h "void unmount();" and add this under :
    bool            Attack(LPCHARACTER pkVictim = NULL);

    It's look like this :

    Then search "CPetActor* GetByVnum(DWORD vnum) const;"
    and add this under :
    void        LaunchAttack(LPCHARACTER pkVictim = NULL);

     

    It's look like this :

     
    fce8dd05ac.png
     
    -> Save and then open PetSystem.cpp:
     
    Search the "bool CPetActor::Update(DWORD deltaTime)" function

    And replace it with this :

    bool CPetActor::Update(DWORD deltaTime)
{
    bool bResult = false;

    if (m_pkOwner->IsDead() || (IsSummoned() && m_pkChar->IsDead())
            || NULL == ITEM_MANAGER::instance().FindByVID(this->GetSummonItemVID())
            || ITEM_MANAGER::instance().FindByVID(this->GetSummonItemVID())->GetOwner() != this->GetOwner()
            )
    {
        this->Unsummon();
        return true;
    }
    
    if (this->GetCharacter()->GetVictim())
    {
        bResult = this->Attack();
    }
 
    if (!bResult)
    {
    if (this->IsSummoned() && HasOption(EPetOption_Followable))
        bResult = this->_UpdateFollowAI();
    }
 
    return bResult;
}
     
    Search the "void CPetActor::ClearBuff()" function
     
    And add this function under :
     
    bool CPetActor::Attack(LPCHARACTER pkVictim)
{
    if (pkVictim)
    {
        if (!pkVictim->IsMonster() || pkVictim->IsDead())
            return false;
 
        if (m_pkChar->GetVictim())
            return false;
    }
    else
    {
        pkVictim = m_pkChar->GetVictim();
 
        if (!pkVictim)
            return false;
    }
 
    m_pkChar->SetVictim(pkVictim);
 
    const PIXEL_POSITION& rkPetPos = m_pkChar->GetXYZ();
    const PIXEL_POSITION& rkVictimPos = pkVictim->GetXYZ();
 
    int iDistance = DISTANCE_APPROX(rkPetPos.x - rkVictimPos.x, rkPetPos.y - rkVictimPos.y);
 
    if (iDistance >= m_pkChar->GetMobAttackRange())
    {
        m_pkChar->Follow(pkVictim, m_pkChar->GetMobAttackRange());
    }
    else
    {
        if (get_dword_time() - m_pkChar->GetLastAttackTime() >= 3000)
        {
            if (m_pkChar->Attack(pkVictim))
            {
                m_pkChar->SendMovePacket(FUNC_ATTACK, 0, rkPetPos.x, rkPetPos.y, 0, get_dword_time());
                m_pkChar->SetLastAttacked(get_dword_time());
        }
 
    }
}
 
return true;
}

    It will look like this:

     
    a0b99abacf.png
     
    Search "bool CPetSystem::Update(DWORD deltaTime)"
     
    And add this above:
     
    void CPetSystem::LaunchAttack(LPCHARACTER pkVictim)
{
    if (!pkVictim)
        return;
 
    for (itertype(m_petActorMap) it = m_petActorMap.begin(); it != m_petActorMap.end(); ++it)
    {
        CPetActor* pkPetActor = it->second;
        if (pkPetActor->IsSummoned())
            pkPetActor->Attack(pkVictim);
    }
}
     
    It will look like this:
     
    b5ab31cc31.png
     
    Save and open "char_battle.cpp" :
     
    Add a the begining :
     
    #include "PetSystem.h"
     
    Then search this function :
     
    "bool CHARACTER::Attack(LPCHARACTER pkVictim, BYTE bType)"
     
    And especially this part:
     
            // only pc sets victim null. For npc, state machine will reset this.
        if (BATTLE_DEAD == iRet && IsPC())
            SetVictim(NULL);
     
    Add this under:
     
            if (BATTLE_DEAD != iRet && IsPC())
        {
            if (m_petSystem && m_petSystem->CountSummoned() > 0)
                m_petSystem->LaunchAttack(pkVictim);
        }
     
    It will look like this:

    Save and open "pvp.cpp"
     

    Then search this function : "bool CPVPManager::CanAttack(LPCHARACTER pkChr, LPCHARACTER pkVictim)"

     
    And add this under :
     
        if (pkChr->IsPet() && pkVictim->IsMonster())
    {
        return true;
    }
 
    if (pkChr->IsMonster() && pkVictim->IsPet())
    {
        return true;
    }
     
    Like this:
