Not getting auras for NPCs

[ejt]

Hey,

I've been stuck for a while now and posting to see if anyone have a solution.

I'm trying to get auras for units and its working great for players but it will not work for NPCs...

My function for getting auras:

std::vector<Aura> WoWUnit::GetAuras()
{
	std::vector<Aura> retval;

	int32 count = Read<int32>(UnitAuraCount);
	int32 first = Read<int32>(UnitAuraFirst);
	uint64 table = Read<uint64>(UnitAuraTable);

	if (count == -1)
		count = first;

	for (int32 i = 0; i < count; ++i)
	{
		Aura aura = ReadRelative<Aura>(table + (sizeof(Aura) * i));
		
		if (aura.SpellId > 0)
			retval.push_back(aura);
	}

	return retval;
}

Aura structure

struct Aura
{
	uint32 unknown_00;
	uint32 unknown_04;
	uint32 unknown_08;
	uint32 unknown_0C;
	uint32 unknown_10;
	uint32 unknown_14;
	uint32 unknown_18;
	uint32 unknown_1C;
	uint32 unknown_20;
	uint8 unknown_24;
	uint8 unknown_25;
	uint8 unknown_26;
	uint8 unknown_27;
	uint32 unknown_2C;
	uint32 unknown_30;
	uint32 unknown_34;
	uint32 unknown_38;
	uint32 unknown_3C;
	uint32 unknown_40;
	uint32 unknown_44;
	uint32 unknown_48;
	uint32 unknown_4C;
	uint32 unknown_50;
	uint32 unknown_54;
	uint32 unknown_58;
	uint32 unknown_5C;
	uint32 unknown_60;
	uint32 unknown_64;
	WoWGUID OwnerGUID;
	uint32 unknown_78;
	uint32 unknown_7C;
	uint32 unknown_80;
	uint32 unknown_84;
	uint32 SpellId;
	uint32 unknown_8C;
	/*
	0x1/1 = Passive hidden?
	0x3/3 = Hidden, incl Find Minerals passive
	0x7/7 = buff? Swift Landing
	0x9/9 = Talent? No, trinket/item passive also
	0xB/11 = Passive buff?
	0xF/15 = Buff?
	0x11/17 = Debuff? Passive? Not removable?
	0x14/20 = Debuff? dispellable?
	0x1C/20 = Debuff? not dispellable?
	0x1D/29 = PvP Rules Enabled (in pvp combat?)
	*/
	uint8 Flags;
	uint8 Stack;
	uint16 CasterLevel;
	uint32 Duration;
	uint32 unknown_98;
	uint32 unknown_9C;
	uint32 unknown_A0;
	uint32 unknown_A4;
};

Offsets relative to unit

	UnitAuraFirst = 0x24D8,
	UnitAuraCount = 0x1A58,
	UnitAuraTable = 0x1A60,

For NPCs, UnitAuraCount comes out as C1200000 and UnitAuraFirst is 0x8 but UnitAuraTable doesn't point to anything useful.

IIRC there should be another aura list, one for staticly allocated and one for dynamicly allocated however I can't for the life of me find it with RE.

Any help or guidance is appreciated.

I'm stupid, the answer was right in front of me this whole time. I forgot that the static list is contained within the unit structure, not outside (via pointer).

Here's the updated code I use, just got it working so can probably be optimized. Posting here for future reference.

std::vector<Aura> WoWUnit::GetAuras()
{
	std::vector<Aura> retval;

	uint64 table = GetAddress() + UnitAuraCount; // 1A58
	int32 count = Read<int32>(UnitAuraFirst);
	if (count == -1) // 24D8
	{
		table = Read<uint64>(UnitAuraTable); // 1A60
		count = Read<int32>(UnitAuraCount);
	}

	for (int32 i = 0; i < count; ++i)
	{
		Aura aura = ReadRelative<Aura>(table + (sizeof(Aura) * i));
		
		if (aura.SpellId > 0)
			retval.push_back(aura);
	}

	return retval;
}
