GUID...Need some help.

[Pixion]

Ok, i think i understood, thank you very much.

[Pixion]

Hello, again...

Since i think i well understood what is, and how works the ObjectManager, i don't know why, but i fond incoherent values.

Here is what I do:

--------Constant values--------
clientConnection = 0x011CA260
o_ToMgr = 0x2864
o_ToFirstObject = 0xAC
o_NextObject = 0x3C
object_GUID = 0x30
-------------------------------

I read it, and i add an offset to get a start of the ObjManager.
It's like that: (clientConnection) + o_ToMgr

Ok, we are at start of the structure.
Then, i add the offset to go at the first object.
This is: (clientConnection) + o_ToMgr + o_ToFirstObject
So... MgrFirst = (clientConnection) + o_ToMgr + o_ToFirstObject

We are now at the first point.
So, in theory, i can get X, Y, Z, and others parameters for this object if i add others offsets.

But now, i just want, for the moment, to find my target's GUID in the ObjectManager.
So, i use a static adress to get my target's GUID. (0x010A58B
And i made a program to loop in search of this GUID, but in the ObjectManager.

So, MyTargetGUID = (0x010A58B
And, MyFoundGUID = MgrFirst + (i * o_NextObject) + object_GUID
(Where "i" is the number wich tells how many times we looped in order to go to next Object after a loop..)

But...I suppose MyFoundGUID is unique, and my program give me, sometimes, sames values (0,0,1...).
So i can conclude that... I don't find the values i expect.

I know this is hard to read, but i wanted to explain how i did as good as possible.

I read some helps on this subject but.. i didn't manage to do what i want.
This include Shynd's guids, and madx ones...

THANKS ALOT.
Pixion.

thats not an array, but a linked list!

            while (!done)
            {
                current_object_guid = (UInt64) WoW.ReadInteger(current_object);
                if (current_object == 0 || (current_object & 0x1) == 0x01)
                    done = true;
                else
                {
                    if (current_object_guid == (guid & 0xFFFFFFFF))
                        return WoW.ReadString(current_object + nameStringOffset, 512);
                    current_object = WoW.ReadInteger(current_object + offset + 4);
                }
            }

I don't understand this part.

if (current_object_guid == (guid & 0xFFFFFFFF))
return WoW.ReadString(current_object + nameStringOffset, 512);
current_object = WoW.ReadInteger(current_object + offset + 4);

What is guid & 0xFFFFFFFF ? 512 ? 4 ?
I've never talk about an array or something else, but what is a "linked list" ?
I thinked it was just..a list...

Thanks.
Pixion.

Linked list - Wikipedia, the free encyclopedia

g3ggo why do you read the guid as a integrer? guid is 8 bytes not 4, you wouldnt get a correct value.

[Sillyboy72]

So, MyTargetGUID = (0x010A58B
And, MyFoundGUID = MgrFirst + (i * o_NextObject) + object_GUID
(Where "i" is the number wich tells how many times we looped in order to go to next Object after a loop..)

No. As stated, its not an array, its a linked list. Go read my ObjectAddressFromGuid again.

I think g3gg0 is vaguely confusing the issues by showing looking for names, in the name cache ... which only uses 4 bytes of the 8 by guid (thus the AND with 0xffffffff).

[Pixion]

Hum, can a GUID be < 0 ?

[hypnodok]

No, you are likely treating them as Int64 instead of UInt64.
So yeah, if your GUIDs turn out to be negative youre doing it wrong.

[g3gg0]

yes, just pasted the code for finding players GUIDs.
sorry for that
was currently reworking that part and so i really mixed that up
still its a linked list and no array.

but here the code to scan all objects.

            while (!done)
            {
                UInt64 objectGUID = WoW.ReadLong(curObj + 0x30);
                UInt64 targetGUID = 0;
                eObjType objectType = (eObjType) WoW.ReadInteger(curObj + 0x14);

                ...

                curObj = WoW.ReadInteger(curObj + 0x3C);

                if (curObj == 0 || (curObj & 0x1) == 0x01)
                    done = true;
            }

[g3gg0]

hmm if you are treating them ans Int64 (signed 64 bit integer) they will be negative.
the highest bit is set on mobs (0x8...) so its treated as a negative number if you
treat that number as signed.
i simply use UInt64 for that, since i dont have any reason to use signs with GUIDs

here some GUIDs

Ok, it works now.
Autoit is a bit hard with Pointers, Hexa calculs and value types (long, int, int64...)

Thanks you.
