GetAura

[nitrogrlie]

So IDA gives following for address 0x0056CA50:

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

  if ( *(_DWORD *)(this + 3536) == -1 )
    v2 = *(_DWORD *)(this + 3156);
  else
    v2 = *(_DWORD *)(this + 3536);
  if ( a2 >= v2 )
  {
    result = 0;
  }
  else
  {
    if ( *(_DWORD *)(this + 3536) == -1 )
      result = *(_DWORD *)(this + 3160) + 24 * a2;
    else
      result = this + 24 * a2 + 3152;
  }
  return result;
}

I am guessing that in reality the return value is a pointer to an Aura struct (probably very similar to the one given via the Lua_UnitAura() function). And the "int a2" argument is the index into the Aura array which you can for loop over and max at the Num of Auras as reported by function at address 0x0049E830:

int __thiscall CGUnit_C__GetAuraCount(int this)
{
  int result; // eax@1

  result = *(_DWORD *)(this + 3536);
  if ( result == -1 )
    result = *(_DWORD *)(this + 3156);
  return result;
}

Am I correct? currently unable to verify this by just running wow... don't ask.

here is my snippet of code to retrieve aura IDs:

int auraCount1 = wow.ReadInt(curObjBase + Offsets::AuraCount1);
int auraCount2 = wow.ReadInt(curObjBase + Offsets::AuraCount2);
//cout << "Aura count #1: " << dec << auraCount1 << endl;
//cout << "Aura count #2: " << dec << auraCount2 << endl;

if(auraCount1 >= 0) { // normal table
    uint tableBase = curObjBase + Offsets::Table1;
    ushort spellID;
    hasAura = false;
    for (int i = 0; i < auraCount1; ++i) {
	spellID = wow.ReadUShort(tableBase + i * Offsets::AuraSize + Offsets::AuraOffset);
	//cout << () << " ";
	if(spellID == 44401) // missle barrage
		hasAura = true;
    }
} else { // extended table
    uint tableBase = wow.ReadUInt(curObjBase + Offsets::Table2);
    ushort spellID;
    hasAura = false;
    for (int i = 0; i < auraCount2; ++i) {
	spellID = wow.ReadUShort(tableBase + i * Offsets::AuraSize + Offsets::AuraOffset);
	//cout << () << " ";
	if(spellID == 44401) // missle barrage
		hasAura = true;
    }

}

I hope it helps

Fyi your code would be a lot cleaner if you removed the code duplication:

int auraCount1 = wow.ReadInt(curObjBase + Offsets::AuraCount1);
int auraCount2 = wow.ReadInt(curObjBase + Offsets::AuraCount2);

int AuraCount = AuraCount1 ? AuraCount1 : AuraCount2;
uint TableBase = wow.ReadUInt(curObjBase + (AuraCount1 ? Offsets::Table1 : Offsets::Table2));

ushort spellID;
hasAura = false;
for (int i = 0; i < AuraCount; ++i) 
{
	spellID = wow.ReadUShort(tableBase + i * Offsets::AuraSize + Offsets::AuraOffset);
	if(spellID == 44401) // missle barrage
		hasAura = true;
}

my bad, thx
