[help][8.3] How to handle Aura? my old code not working?

[chlycooper]

i used

$auraCount = _MemoryRead($NextObject1 + $AuraCount1, $hWow, 'dword')
$auraTable = $NextObject1 + $AuraTable1
If $auraCount > 80 Then
	$auraTable = _MemoryRead($NextObject1 + $AuraTable2, $hWow, 'dword')
	$auraCount = _MemoryRead($NextObject1 + $AuraCount2, $hWow, 'dword')
EndIf
For $I = 0 To $auraCount - 1
		Local $spellId = _MemoryRead($auraTable + $AuraSize * $I + $AuraSpellId, $hWow, 'dword')
Next

is it changed ? or i just use the wrong offset? I tried some , can't get them.

You will need to supply more info on your constants for anyone to help you.

i got from other post, but i can't make it work.
$AuraCount2 = 0x600 (from a post for 8.3)
$AuraCount1 = $AuraCount2 + 0xA80 (from a post for 8.3)
and:
Aura_Count2 = 0x5f8
Aura_Count1 = Aura_Count2 + 0xA80
Aura_Table1 = Aura_Count2 (from a post for 8.25)
Aura_Table2 = Aura_Count2 + 0x8 (from a post for 8.25)

$NextObject is the LocalPlayobj address

Find Script_GetSpellConfirmationPromptsInfo and look around 0x75 from the start of the subroutine, you will see the 0x600 and the 0xa80 offsets. That section of the code shows you how to use them properly. You can also find the Size of the Aura Entry and the Offset of SpellId into the Aura Entry a bit further down.

thank you , big help, i will try it.

Not sure where you got the 'auraCount > 80' from but here is how wow handles auras

void Unit::UpdateAllAuras()
{
	auras.clear();

	uint64_t table = address() + offsetof(CGUnit, AuraCount); // 0x600
	int32_t count = unit_data->AuraFirst; // 0x1080

	if (count == -1)
	{
 		table = unit_data->AuraTable; // 0x608
		count = unit_data->AuraCount; // 0x600
	}

	for (int32_t i = 0; i < count; ++i)
	{
                // sizeof CGAura = 0xA8
		Aura aura = Aura(_process->memory().Read<CGAura>(table + (sizeof(CGAura) * i)));
               
                // spell_id is at 0x88
		if (aura.GetSpellId() > 0)
			auras.emplace_back(Aura(aura)); 
	}
}

You can reverse the UnitBufff API function and it will call a function that has this:

    v5 = sub_D65700(v3, *(unsigned int *)(v2 + 0x10), *(unsigned __int8 *)(v2 + 0x14));
    v6 = v5;
    if ( (v5 & 0x80000000) != 0 )
      goto LABEL_13;
    v7 = v3 + 0x600;
    v8 = 0xA8i64 * v5;
    if ( *(_DWORD *)(v3 + 0x1080) == -1 )
      v7 = *(_QWORD *)(v3 + 0x608);
    v9 = *(_DWORD *)(v8 + v7 + 0x88);
    v10 = (signed int *)sub_465050(&off_28D8B40, *(unsigned int *)(v8 + v7 + 0x88), 0i64, &v21);
    if ( v10 )
    {
      v11 = sub_B79EA0(v3, v6);
      result = sub_166DDE0(v9, v11, v20, v4, v10, v3);
    }

which is similar to the code above

thank you, i make it working , a lot to learn....

which is similar to the code above

// sizeof CGAura = 0xA8 maybe changed in 8.3.
for (int i = 0; i < count; ++i)
{
Aura aura = new Aura (process, process.Read<IntPtr>(address + 0x608 + (0xA8 * i)))
if (aura.GetSpellId() > 0 )
auras.Add(aura);
}

Size of CGAura is still 0xA8 as you can see from

v8 = 0xA8i64 * v5;

and I'm not sure why you do

address + 0x608 + (0xA8 * i)

when thats not how I showed you.

i was made a mistake, now i got my spell id by

  int spellid = process.Read<int>(table + (0xA8 * i) + 0x88)

thanks.
