Changing who you can NOT attack in PvP areas

[kjkrum]

Normally, in PvP areas like Gurubashi Arena, you cannot attack members of your party. What controls who you cannot attack? Could it be extended to, say, your guild, or your race?

maybe in Player::UpdateArea? there is the way to start i think

I think the main function to modify are IsHostileTo and IsFriendlyTo in Unit.cpp :

   // special cases (Duel)
   if(tester->GetTypeId()==TYPEID_PLAYER && target->GetTypeId()==TYPEID_PLAYER)
   {
       Player const* pTester = (Player const*)tester;
       Player const* pTarget = (Player const*)target;

       // Duel
       if(pTester->duel && pTester->duel->opponent == target && pTester->duel->startTime != 0)
           return false;

       // Group
       if(pTester->GetGroup() && pTester->GetGroup()==pTarget->GetGroup())
           return true;

       // Sanctuary
       if(pTarget->HasByteFlag(UNIT_FIELD_BYTES_2, 1, UNIT_BYTE2_FLAG_SANCTUARY) && pTester->HasByteFlag(UNIT_FIELD_BYTES_2, 1, UNIT_BYTE2_FLAG_SANCTUARY))
           return true;

       // PvP FFA state
       if(pTester->IsFFAPvP() && pTarget->IsFFAPvP())
           return false;

       //= PvP states
       // Green/Blue (non-attackable)
       if(pTester->GetTeam()==pTarget->GetTeam())
           return true;

       // Blue (friendly/non-attackable) if not PVP, or Yellow/Red in another case (attackable)
       return !pTarget->IsPvP();
   }

Just add some conditions here, or modify the order of them
