Memory Reading

Chuuy · June 11, 2009

First, I'll give a brief explanation of the program I'm coding.

Basically, it clicks in one spot and then in another spot to refresh a list. When an address on that list contains the value 1082002, then check if another address contains the value < 1335. If so, then buy.

So, I found this:

;=================================================================================================
; Function:   _MemoryRead($iv_Address, $ah_Handle(, $sv_Type))
; Description:  Reads the value located in the memory address specified.
; Parameter(s):  $iv_Address - The memory address you want to read from. It must be in hex
;                         format (0x00000000).
;              $ah_Handle - An array containing the Dll handle and the handle of the open
;                        process as returned by _MemoryOpen().
;              $sv_Type - (optional) The "Type" of value you intend to read.  This is set to
;                       'dword'(32bit(4byte) signed integer) by default.  See the help file
;                       for DllStructCreate for all types.
;                       An example: If you want to read a word that is 15 characters in
;                       length, you would use 'char[16]'.
; Requirement(s):   The $ah_Handle returned from _MemoryOpen.
; Return Value(s):  On Success - Returns the value located at the specified address.
;              On Failure - Returns 0
;              @Error - 0 = No error.
;                     1 = Invalid $ah_Handle.
;                     2 = $sv_Type was not a string.
;                     3 = $sv_Type is an unknown data type.
;                     4 = Failed to allocate the memory needed for the DllStructure.
;                     5 = Error allocating memory for $sv_Type.
;                     6 = Failed to read from the specified process.
; Author(s):        Nomad
; Note(s):    Values returned are in Decimal format, unless specified as a 'char' type, then
;              they are returned in ASCII format.  Also note that size ('char[size]') for all
;              'char' types should be 1 greater than the actual size.
;=================================================================================================
Func _MemoryRead($iv_Address, $ah_Handle, $sv_Type = 'dword')
    
    If Not IsArray($ah_Handle) Then
        SetError(1)
        Return 0
    EndIf
    
    Local $v_Buffer = DllStructCreate($sv_Type)
    
    If @Error Then
        SetError(@Error + 1)
        Return 0
    EndIf
    
    DllCall($ah_Handle[0], 'int', 'ReadProcessMemory', 'int', $ah_Handle[1], 'int', $iv_Address, 'ptr', DllStructGetPtr($v_Buffer), 'int', DllStructGetSize($v_Buffer), 'int', '')
    
    If Not @Error Then
        Local $v_Value = DllStructGetData($v_Buffer, 1)
        Return $v_Value
    Else
        SetError(6)
        Return 0
    EndIf
    
EndFunc

What is $ah_Handle, or how do I find it?

I also have another question, for the Buy function I want to do at the end, is it possible to send a packet to the game? If not, I can just click here, then here, and it'll buy like that, but packets would be faster, and I need to make this as fast as possible. Thanks.

That's from NomadMemory, many threads about that.

First you need to use _MemoryOpen

Chuuy · June 11, 2009

Alright, I was thinking completely differently then I should've been. So now I have this.

#include "NomadMemory.au3"

_MemoryOpen($iv_Pid = , $iv_DesiredAccess = 0x1F0FFF, $if_InheritHandle = 1) ; Will find the PID later


Do Refresh()
    Until _MemoryRead($iv_Address = , $ah_Handle, $sv_Type = 'dword') = 1082002 ; Will find the address later

If _MemoryRead($iv_Address = , $ah_Handle, $sv_Type = 'dword') < 1355 ; Will find the address later
    Then Buy()
    
Func Refresh()
    MouseClick ( "main" [, x, y [, 1 [, 0 ]]] ) ; Will find mouse xy coords later
    MouseClick ( "main" [, x, y [, 1 [, 0 ]]] ) ; Will find mouse xy coords later
    Return
EndFunc

Func Buy()
    MouseClick ( "main" [, x, y [, 1 [, 0 ]]] ) ; Will find mouse xy coords later
    MouseClick ( "main" [, x, y [, 1 [, 0 ]]] ) ; Will find mouse xy coords later
    Return
EndFunc

It has been a while since I last used AutoIt, so I'm not sure if this would do what I want it to do.

Man I keep noticing that I'm doing a lot of syntax errors.

Here's the code I have now, I think this is correct:

#include "NomadMemory.au3"

Dim $Item, $Price

_MemoryOpen($iv_Pid =, $iv_DesiredAccess = 0x1F0FFF, $if_InheritHandle = 1)
_MemoryRead($iv_Address =, $ah_Handle, $sv_Type = 'dword') = $Item
_MemoryRead($iv_Address =, $ah_Handle, $sv_Type = 'dword') = $Price

Do Refresh()
Until $Item = 1082002

If $Price < 1355
    Then Buy()
EndIf

Func Refresh()
    MouseClick("main"[, x, y[, 1[, 0]]])
    MouseClick("main"[, x, y[, 1[, 0]]])
    Return
EndFunc   ;==>Refresh

Func Buy()
    MouseClick("main"[, x, y[, 1[, 0]]])
    MouseClick("main"[, x, y[, 1[, 0]]])
    Return
EndFunc   ;==>Buy

EDIT: Declared variables. =0

I'm completely confusing myself with which loops I should use when.

Maybe someone can tell me what type of loop to use if I want to process these statements this way:

Refresh() until $Item = 1082002, if not restart Refresh(). Check if $Price < 1355, if not restart Refresh(), if so then Buy(). Then restart at Refresh().

I know I need to include these functions:

_MemoryOpen($iv_Pid =, $iv_DesiredAccess = 0x1F0FFF, $if_InheritHandle = 1) ; I'm guessing this goes at the top and only needs to be run once?
_MemoryRead($iv_Address =, $ah_Handle, $sv_Type = 'dword') = $Item ; Reads the value at the address and sets it as $Item, I want it to stop if $Item = 1082002, and then to check if &Price < 1355.
_MemoryRead($iv_Address =, $ah_Handle, $sv_Type = 'dword') = $Price ; Reads the value at the address and sets it as $Price, I want it to stop if $Price < 1355, and I want it to Buy() if true.  Then I want the code to start again at Refresh().oÝ÷ Ù8^±æ«zlºw-ìjëh×6Func Refresh()

Before you go ahead, you should test your values.

MsgBox (0, "", _MemoryRead($iv_Address =, $ah_Handle, $sv_Type = 'dword') = $Item)

MsgBox (0, "", _MemoryRead($iv_Address =, $ah_Handle, $sv_Type = 'dword') = $Price)

Put these messages, are you reading the correct stuff ?

Also, your syntax is horribly wrong :-(

Well, I haven't added in the address to read for yet, I want to write the code first, then I'll load up Cheat Engine/Ollydbg and add in the addresses, the PID, and the mouse xy coordinates.

Can you tell me what's wrong with my syntax. =0 I'm really struggling with this.

Well it's me again. I revised my code, and I believe this is correct syntax. Please check it over, thanks.

Dim $Item, $Price

_MemoryOpen($iv_Pid =, $iv_DesiredAccess = 0x1F0FFF, $if_InheritHandle = 1) ; Will set PID later

Well, I was basically copying the functions along with the parameters from NomadMemory.au3, and he defined variables in the parameters. Unless you meant x and y under MouseClick, that's because each click is going to be in a different spot. Also, should I declare the value of $iv_Address as a local address? But that wouldn't work, because they're both different addresses. Should I just write in the address like below?

So, this code would work fine for my purposes:

#include <NomadMemory.au3>

Dim $Item, $Price

$ah_Handle=_MemoryOpen("MapleStory.exe")

While 1
    Local $iv_Address
    MouseClick("main", x, y, 1, 0) ; Will set x and y later
    MouseClick("main", x, y, 1, 0) ; Will set x and y later
    $Item=_MemoryRead(0x000000, $ah_Handle) ; Will change to correct address later
    $Price=_MemoryRead(0x000000, $ah_Handle) ; Will change to correct address later
    If $Item = 1082002 And $Price < 1355 Then
        MouseClick("main", x, y, 1, 0) ; Will set x and y later
        MouseClick("main", x, y, 1, 0) ; Will set x and y later
    EndIf
WEnd

No need to declare variables for the addresses then in my opinion then

And yeah, that code should work

Edit; I saw that your making this for Maplestory, I've heard that they got a gameguard, I'm pretty sure it will pick this up.

So cheating won't really pay of :/

Alright, thanks a lot.

I'm going to be expanding this into a bigger and more automated bot, so I'll post if I have any more problems, but for now, this is great and I need to load up Cheat Engine. Thanks.

Oh sorry, one more thing. Does anyone know anything about sending packets with AutoIt?

Zisly · June 11, 2009

Check out TCP in the help file.

Ooh, alright, thanks again!

I'm having trouble trying to send packets.

#include <NomadMemory.au3>

$ah_Handle = _MemoryOpen("MapleStory.exe")
$SocketID = TCPConnect(63.251.217.122, 8989)

    $Price = _MemoryRead(0x000000, $ah_Handle) ; Will change to correct address later

        MouseClick("main", 448, 366, 1, 0) ; Will set x and y later
    EndIf
WEnd

I have the IP and port of what I want to send packets to, and I also have the packet. But I'm getting syntax errors.

Do you solve this by putting quotes around the IP and packet? Because I did that, and it compiled, but it wasn't working.

No one knows about sending packets?

You need to startup tcp.. read the examples in the helpfile next time.

#include <NomadMemory.au3>

Alright thanks, but I'm having trouble with this, and it's not the most imporant part, so I'm just going to go back to clicking with MouseClick.

However, a new question. It appears that they encrypted the price and that I can't read it out of memory, is it possible to use OCR or something of the sort to read the number?

EDIT: Well, I've found a lot of examples over the forum, so lets see what happens.

Update: Nevermind, I found the price in the memory. Should be good now.

Hi, it's me again. I'm basing the entire program off of reading and sending packets, but I have a few questions on recieving packets. Basically, when I TCPSend the first packet, it refreshes a list. When a new item is added to the list, I recieve a packet, which is what I'm trying to recieve in TCPRecv. Now, I want to read this packet. The packet I recieve will look like this:

37 01 15 A6 B8 00 00 10 00 00 00 01 00 00 00 02 00 00 00 00 00 00 00 01 01 02 E4 23 1F 00 00 00 80 05 BB 46 E6 17 02 02 00 00 00 00 00 2F 29 BE 01 8C 0A 00 00 72 01 00 00 00 00 00 00 00 D6 5B 5D A4 F1 C9 01 07 00 4D 61 78 41 75 72 61 0B 00 53 49 4E 64 55 52 75 6E 6E 69 6E 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 02 E4 23 1F 00 00 00 80 05 BB 46 E6 17 02 01 00 00 00 00 00 2D 29 BE 01 6C 07 00 00 22 01 00 00 00 00 00 00 00 D6 5B 5D A4 F1 C9 01 07 00 66 75 6C 61 6E 6F 78 0C 00 52 6F 43 6B 53 74 61 52 6C 78 58 78 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 02 25 21 1F 00 00 00 80 05 BB 46 E6 17 02 01 00 00 00 00 00 29 29 BE 01 6E 00 00 00 6F 00 00 00 00 00 00 00 00 D6 5B 5D A4 F1 C9 01 09 00 61 6E 74 31 66 72 33 33 7A 0C 00 45 6E 74 68 75 73 69 65 73 74 69 63 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 02 41 2D 1F 00 00 00 80 05 BB 46 E6 17 02 01 00 00 00 00 00 20 29 BE 01 6E 00 00 00 6F 00

The red part is the item ID, and the green part is the price. When the item ID = E4 23 1F And Price < 4B 05 then send the second packet where XX XX XX = The part above highlighted in Blue. I didn't see anything in the help file about this, and neither did searching the forum. So could I get some help please? Thank you.
