This is what I use for CyberFish:
Code:
; Checks if object was created by you
; $oBase => object base
; True = yes
; False = no
Func _ObjCreatedbyYou($oBase)
Local $createdby = _MemoryRead(_MemoryRead($oBase + 0x8, "uint") + (0x6 * 4), "dword")
; check to see if the creator is you!
If $createdby = _getPlayerGUID() Then
Return True
Else
Return False
EndIf
EndFunc
Where _getPlayerGUID() returns the GUID of my character. You will have to cycle through your objects and plug them in with each iteration. But this simply returns a boolean.
