Help understanding the object manager, and getting information on a target

[jpbanon]

Hey guys! I'm still kind of new here, and I'm learning pretty quick, but there is still alot I don't quite understand yet.

I know how to access memory etc, and I'm successfully getting my player's health, mana, and xyz based on the static player base.

Right now I'm trying to learn how to get information on targets, and this seems alot more complicated.

My impression is that a target NPC is an object, of which there are a few types, such as items, NPCs, Players, corpses etc. It seems that these are stored as structs containing many variables and different data types.

What I don't quite understand is how I use a GUID, and how these relate to an 'objectmanager' which sounds like a linked list of all of the objects and has pointers to the various objects.


This is the code I have for my object structs:

Func _wowObject() ; misc
	Return DllStructCreate( _
			"uint staticClientConnection;" 	& _
			"uint DataPTR;"				& _ 
			"uint64 GUID;" 				& _
			"uint FirstObject;" 			& _
			"uint NextObject;") 
EndFunc   ;==>_wowObject

Func _wowUnitObject() ;
	Return DllStructCreate( _
			"uint64 GUID;" 				& _
			"ptr NextObject;"				& _
			"dword ObjectType;" 			& _
			"float x;" 					& _
			"float y;" 					& _
			"float z;" 					& _
			"float rot;" 					& _
			"uint64 DescriptorFieldsOffset;")
EndFunc   ;==>_wowUnitObject

Func _wowObjectData()
	return DllStructCreate ( 								_
		"uint64 charm;"								&	_
		"uint64 summon;"								&	_

* Please forgive some of the random spacing, the code didn't copy well.

I understand that these are outdated, and I am confident I can update the information in _wowObjectData to the correct information using the information at wow-3-3-2-info-dump-thread.

I cannot find anything that is equivalent to either _wowObject or _wowUnitObject. Can anyone provide some insight into this? My guess is that _wowObject is related to

public enum ObjectManager
        {

            CurMgrPointer = 0x00C93410,          // 3.3.2
            CurMgrOffset = 0x2E04,               // 3.3.2
            localGuidOffset = 0xC0,              // 3.3.2
            firstObjectOffset = 0xAC,            // 3.3.2
            nextObjectOffset = 0x3C,             // 3.3.2

        }

from the same thread, but I am not sure. I also don't know how to translate those offsets into datatypes if in fact it is the same.


Here is a selection of my code for traversing the object manager:

Func _getObjectOffset($objectCondition)

	_ReadProcess($wowProcessHwnd, $baseObjectPTR + 0x2E04, $buffer_ptr)

	$currentObject = DllStructGetData($buffer_ptr, 1)
	$wowObject = _wowObject()

	$wowObjectData = _wowObjectData()

	$guid = 0
	$next = 0

	While ($currentObject <> 0 And Mod(Number($currentObject), 2) == 0)

		_ReadProcess($wowProcessHwnd, $currentObject, $wowObject)

		$guid = DllStructGetData($wowObject, 'GUID')
		$next = DllStructGetData($wowObject, 'NextObject')
		$data = DllStructGetData($wowObject, 'DataPTR')

		Switch ($objectCondition)
			Case $C_PLAYER
				If ($guid == $playerID) Then
					_ReadProcess($wowProcessHwnd, $currentObject, $player)
					_ReadProcess($wowProcessHwnd, $data, $playerData)
					Return $currentObject
				EndIf
		EndSwitch

		$currentObject = $next

	WEnd
EndFunc   ;==>_getObjectOffset

Your help and patience are greatly appreciated.

Hello, First welcome to MMOwned! ^^

I'm going to try and help you, but first i'm going to warn you... You won't of seen Apoc's "Enough is Enough" thread because you are new, but I suggest you go read it.

Now on to(hopefully) helping you.

NPC and Players ect, are stored in the Object Manager as uint.
A GUID is a unique ID for that realm. Everything that's stored in the Object Manager has a GUID, and can be used to find their name, health, mana, xyz locations ect. To get this info you need to look at the descriptors for this patch(although they don't change much )


So for example GUID + Name1 + Name2 = Objects/uints name

Hope I helped

[jpbanon]

XAutomation, thank you for your reply!

I have done a search for the "Enough is Enough" thread. I also looked at Apoc's last 100 posts, could it be old enough that it went away?

Regarding my question:

So, at the moment I have a target. The uint I get from 0x00B695C8 is -1067353103885382925 which in hex is 0xF1300001D1004AF3.

So that would be the GUID. So when you say Name1 and Name2, what would those be? Are those the descriptor offsets?

Do you mean something like this?
0xF1300001D1004AF3 + 0x17 // 3.3.2 UNIT_FIELD_HEALTH = 0x17

I can't get that to return the health of my target.

I apologize for my lack of understanding.

A uint is a 32 bit field. Not a 64 bit. You're reading a 64 bit field. Fix yo' shit!

[Mr.Zunz]

You should read GUID as an Ulong, most of the rest can be done by UInt

[boredevil]

I would suggest, reading this post.

That´s what gave me a pretty good start at pulling object data from wow.

A GUID is a unique ID for that realm.

Incorrect. GUIDs are shared, at the very least, across battlegroups.

[MaiN]

Incorrect. GUIDs are shared, at the very least, across battlegroups.

Incorrect. GUID's are unique on a per-server basis.

Uniqueness is guaranteed in cross-realm battlegrounds by masking the player GUID with a server specific unique identifier, when needed.

API UnitGUID - WoWWiki - Your guide to the World of Warcraft

[Apoc]

Le sigh.

GUIDs are unique on a per-server basis, excluding player GUIDs. Of which are unique at a per-battlegroup level. (Quite possibly unique across all server 'types'. [US, Oceanic, EU, etc])

Player GUIDs need the 'extra' uniqueness to allow cross-server BGs/Arenas and the like.

[XTZGZoReX]

Yeah, let me correct myself: Player GUIDs are unique on a per-battlegroup basis. All other GUIDs on a per-map basis, as far as my research shows.
