Problem getting base address / pointer read

[wootpeng]

For some reason my base address is always returning 0. Anyone know why?

$Mem_Open = _MemoryOpen(WinGetProcess("Diablo III")) ;must open before you can read address
$baseAddress = _MemoryGetBaseAddress($Mem_Open, 1)

MsgBox(0,0,$baseAddress)

Local $offset[3]
$offset[0] = 0
$offset[1] = Dec("C")
$offset[2] = Dec("D8")

$staticOffset = Dec("00FC85B0") - Dec($baseAddress)
$finalAddress = "0x" & Hex(Dec($baseAddress) + $staticOffset)
$pAddress = _MemoryPointerRead($finalAddress, $Mem_Open, $Offset)

Your static offset needs to be the Base address + the Relative address. You're getting a negative number, no doubt.


Other than that the disgusting syntax of whatever you're using is making my eyes bleed. Give my suggestion a try however and see where it gets you.

Have you read his question? he said "base address is always returning 0"... I think he is refering to this MsgBox(0,0,$baseAddress)...
My autoit script had the same problem, don't know why...

; Return Value(s).:  On Success - Returns the 'allocation Base' address and sets @Error to 0.
;                    On Failure - Returns 0 and sets @Error to:
;                       |1 = Invalid $ah_Handle.
;                       |2 = Failed to find correct allocation address.
;                       |3 = Failed to read from the specified process.

What does your Error flag tell you ?

"2 = Failed to find correct allocation address." is the flag.

I figured out why the base address was returning 0. This thread solved the issue: Memory UDF - Page 3 - Example Scripts - AutoIt Forums

Now the problem is I my pointerread value is returning 0. I feel like it still has to do with the base address because if I compare it with cheat engine they are different.

here's an example, tare it apart and use it to your advantage..

you need 2 files,
one is the infamous Nomadmemory.au3 and the second one is this: [AutoIt] Func _MemoryModuleGetBaseAddress($iPID, $sModule) If Not ProcessExists($iPI - Pastebin.com

 #include <NomadMemory.au3>
 #include <memmodulebaddr.au3>

        Global $PID
        Global $sModule = "MemoryMan.dll"
        Global $StaticOffset
        Global $openmem

        $PID = ProcessExists("Tutorial-i386.exe")
	$openmem = _MemoryOpen($PID)
	$StaticOffset = Dec("006903C0") ;base addr (green) was the same both times - this is the correct base addr..


Global $Offset1[3]
$Offset1[0] = 0 ; Is ALWAYS 0.
$Offset1[1] = Dec("49c") ; 2nd pointr
$Offset1[2] = Dec("4") ; 1st pointr

	$baseADDR = _MemoryModuleGetBaseAddress($PID, $sModule)
	$finalADDR = "0x" & Hex($baseADDR + $StaticOffset)

While 1 ;loop
Sleep(1000)

	$r = _MemoryRead($finaladdr,$openmem)
	$r = _MemoryRead($r + $Offset1[1],$openmem)
	$r = _MemoryRead($r + $Offset1[2],$openmem, "float")

	;Base addr instead of $openmem? or not ?

		ToolTip("PID: " & $PID & @CRLF _
		&	"baseaddr: " & $baseADDR &@CRLF _
		&	"finaladdr: " & $finalADDR & @CRLF _
		&	"hp: " & $r & @CRLF _
		&	"openMem: " & $openmem, 0, 0)

WEnd
Sleep(1000)

The issue with pAddress is what tried to explain ssknight: you did apply some weird formula.

$staticOffset = Dec("00FC85B0") - Dec($baseAddress)
$finalAddress = "0x" & Hex(Dec($baseAddress) + $staticOffset)

Or in one line:

$finalAddress = "0x" & Hex(Dec($baseAddress) + Dec("00FC85B0") - Dec($baseAddress))

Hope you'll see what's wrong here.

Alright, I changed my code to this but am still not receiving a correct address or number. Do I have the formula correct now?

Local $offset[3]
$offset[0] = 0
$offset[1] = Dec("C")
$offset[2] = Dec("D8")

$staticOffset = Dec("00FC85B0")
$finalAddress = "0x" & Hex(Dec($baseAddress) + $staticOffset)
MsgBox(0,0,$finalAddress)
$pAddress = _MemoryPointerRead($finalAddress, $Mem_Open, $offset)

MsgBox(0,0,$pAddress[1])
