[Code]what's the meaning of member m_ObjectSlot of class Unit?

[kimxee]

m_ObjectSlot[4] in class Unit line 1555

Is it for warlocks' summoning? Which spell is it?

It's used for void Spell::EffectSummonObject(SpellEffectIndex eff_idx) for storing the GUIDs of objects summoned by spells.

Creatures also can summon own gameobjects (in different wild gameobjects that not have owner). Owner set faction gameobject /etc.

;)Thanks!

I'd read the function void Spell::EffectSummonObject(SpellEffectIndex eff_idx) ,and it has the following code:

switch(m_spellInfo->Effect[eff_idx])
   {
       case SPELL_EFFECT_SUMMON_OBJECT_SLOT1: slot = 0; break;
       case SPELL_EFFECT_SUMMON_OBJECT_SLOT2: slot = 1; break;
       case SPELL_EFFECT_SUMMON_OBJECT_SLOT3: slot = 2; break;
       case SPELL_EFFECT_SUMMON_OBJECT_SLOT4: slot = 3; break;
       default: return;
   }

So I traced these definetion,found :

in file Spell.cpp, line 3480 in function void Spell::SendLogExecute() callby void Spell::_handle_finish_phase()

case SPELL_EFFECT_SUMMON_OBJECT_SLOT1:
case SPELL_EFFECT_SUMMON_OBJECT_SLOT2:
case SPELL_EFFECT_SUMMON_OBJECT_SLOT3:
case SPELL_EFFECT_SUMMON_OBJECT_SLOT4:
   if(Unit *unit = m_targets.getUnitTarget())
       data << unit->GetPackGUID();
   else if(m_targets.getItemTargetGUID())
       data.appendPackGUID(m_targets.getItemTargetGUID());
   else if(GameObject *go = m_targets.getGOTarget())
       data << go->GetPackGUID();
   else
       data << uint8(0);                   // guid
   break;

:|Does it mean Only when SLOT4 reached can I get the GameobjectTarget's Guid? As I haven't been playing wow for a year, I can't remember which spell / mob or other stuff fits this situation...

In fact not many for creatures case. This is creature versions hunter traps + 2 less clear cases.
