Buffs

[Arutha532]

I have been trying to dump the player buffs but it has turned out to be a bit random if i receive valid results.

internal enum UnitAuras : uint
{
	CGUnit_Aura = 0x00556E10,                   // 3.3.5a 12340
	AURA_COUNT_1 = 0xDD0,                       // 3.3.5a 12340
	AURA_COUNT_2 = 0xC54,                       // 3.3.5a 12340
	AURA_TABLE_1 = 0xC50,                       // 3.3.5a 12340
	AURA_TABLE_2 = 0xC58,                       // 3.3.5a 12340
	AURA_SIZE = 0x18,                           // 3.3.5a 12340
	AURA_SPELL_ID = 0x8                         // 3.3.5a 12340

} ;

 public List<int> GetBuffs()
{
	List<int> auras = new List<int>();
	try
	{
		int auraCount = ObjectManager.Memory.ReadInt(BaseAddress + (uint)Offsets.UnitAuras.AURA_COUNT_1);
		uint auraTable = ObjectManager.Memory.ReadUInt(BaseAddress + (uint) Offsets.UnitAuras.AURA_TABLE_1);
		if (auraCount == -1)
		{
			auraCount = ObjectManager.Memory.ReadInt(BaseAddress + (uint) Offsets.UnitAuras.AURA_COUNT_2);
			auraTable = ObjectManager.Memory.ReadUInt(BaseAddress + (uint) Offsets.UnitAuras.AURA_TABLE_2);
		}
		int SpellID;                
		for (uint i = 0; i < auraCount; i++)
		{
			SpellID = ObjectManager.Memory.ReadInt(auraTable + ((uint) Offsets.UnitAuras.AURA_SIZE*i) +
											 (uint) Offsets.UnitAuras.AURA_SPELL_ID);
			if (SpellID > 0)
			{
				auras.Add(SpellID);
			}
		}
		return auras;
	} catch (Exception e)
	{
		Console.WriteLine("Exception: GetBuffs: " + e);
		return auras;
	}
}

If i enter my level 80 i can get it to return valid results if i play a bit.
If i create a new level 1 char i cannot get it to return anything valid.

Any help would be very much appreciated.

There are plenty of info on how to do it in this very section, but w/e. Have a look on how WoW does it internally:

int __thiscall CGUnit_C__GetAura(int this, unsigned int a2)
{
  unsigned int v2; // edx@2
  int result; // eax@6

  if ( *(_DWORD *)(this + 0xDD0) == -1 )
    v2 = *(_DWORD *)(this + 0xC54);
  else
    v2 = *(_DWORD *)(this + 0xDD0);
  if ( a2 >= v2 )
  {
    result = 0;
  }
  else
  {
    if ( *(_DWORD *)(this + 0xDD0) == 0xFFFFFFFF )
      result = *(_DWORD *)(this + 0xC58) + 24 * a2;
    else
      result = this + 24 * a2 + 0xC50;
  }
  return result;
}

First argument is the pointer to the object you wish to get the aura from, and the second one is the "slot" to read from in the buff array.
Edit: Maybe I should also add (tho quite obvious) that the above returns the pointer to the buff. You can then do whatever, like read (pointer + AURA_SPELL_ID) to get spell id.

Am I the only one who is baffled like this.. It kind of looks like WoW uses a union here, doesn't it?

Found the bug....

uint auraTable = ObjectManager.Memory.ReadUInt(BaseAddress + (uint) Offsets.UnitAuras.AURA_TABLE_1);
Should be:
uint auraTable = BaseAddress + (uint) Offsets.UnitAuras.AURA_TABLE_1;

Thank you for the help.
