Hi,

I already tried some snippet for Multi-Level Pointer from this forum but unfortunately I got no result.

This is the Multi-Level Pointer I found for Unlimited Sun hack in Plants vs. Zombies.

Photo of Multi-Level Pointer: hxxps://s26.postimg.org/n6iaoj2fd/image.jpg

Here is the 1st code.

Code:

function GetModuleBaseAddress(ProcessID: Cardinal; MName: String): Pointer;
var
  Modules         : Array of HMODULE;
  cbNeeded, i     : Cardinal;
  ModuleInfo      : TModuleInfo;
  ModuleName      : Array[0..MAX_PATH] of Char;
  PHandle         : THandle;
begin
  Result := nil;
  SetLength(Modules, 1024);
  PHandle := OpenProcess(PROCESS_QUERY_INFORMATION + PROCESS_VM_READ, False, ProcessID);
  if (PHandle <> 0) then
  begin
    EnumProcessModules(PHandle, @Modules[0], 1024 * SizeOf(HMODULE), cbNeeded);
    SetLength(Modules, cbNeeded div SizeOf(HMODULE));
    for i := 0 to Length(Modules) - 1 do //Start the bucle
    begin
      GetModuleBaseName(PHandle, Modules[i], ModuleName, SizeOf(ModuleName));
      if AnsiCompareText(MName, ModuleName) = 0 then
      begin
        GetModuleInformation(PHandle, Modules[i], @ModuleInfo, SizeOf(ModuleInfo));
        Result := ModuleInfo.lpBaseOfDll;
        CloseHandle(PHandle);
        Exit;
      end;
    end;
  end;
end;

procedure TForm1.bPointerClick(Sender: TObject);
var
  WHandle : HWND;
  PHandle: THandle;
  Address, X, Buffer: DWORD;
  NewValue: Cardinal;
  ProcessID : Cardinal;
begin
  ProcessID := 0;
  NewValue := $09;
  WHandle := FindWindow(nil, 'Plants vs. Zombies');
  if wHandle = 0 then
  begin
  ShowMessage('notfound');
  end else
  begin
  GetWindowThreadProcessId(WHandle, @ProcessID);
  Address := Integer(GetModuleBaseAddress(ProcessID, 'popcapgame1.exe')) + Integer($002A9EC0);
  PHandle := OpenProcess(PROCESS_ALL_ACCESS, False, ProcessID);
  ReadProcessMemory(PHandle, Ptr(Address + $768), Addr(Buffer), 4, X);
  ReadProcessMemory(PHandle, Ptr(Buffer + $5560), Addr(Buffer), 4, X);
  WriteProcessMemory(PHandle, Ptr(Buffer), @NewValue, 1, X);
  CloseHandle(PHandle);
  end;
end;




Here is the 2nd code.

Code:

function AddressOfMultiLevelPointer(Access: THandle; InitialAddress: Cardinal;
  Offsets: array of Cardinal): Cardinal;
var
  Address: Cardinal;
  Buff: Cardinal;
  Read: Cardinal;
  i: integer;
begin
  Address := InitialAddress + Offsets[ High(Offsets)];
  ReadProcessMemory(Access, Pointer(Address), @Buff, SizeOf(Buff), Read);
  for i := High(Offsets) - 1 downto 1 do
  begin
    Address := Buff + Offsets[i];
    ReadProcessMemory(Access, Pointer(Address), @Buff, SizeOf(Buff), Read);
  end;
  Result := Buff + Offsets[0];
end;

function GetProcessIDByName(Exename: String): DWord;
var
  hProcSnap: THandle;
  pe32: TProcessEntry32;
begin
  Result := 0;
  hProcSnap := CreateToolHelp32SnapShot(TH32CS_SNAPPROCESS, 0);
  if hProcSnap <> INVALID_HANDLE_VALUE then
  begin
    pe32.dwSize := SizeOf(ProcessEntry32);
    if Process32First(hProcSnap, pe32) = True then
    begin
      while Process32Next(hProcSnap, pe32) = True do
      begin
        if pos(Exename, pe32.szExeFile) <> 0 then
          Result := pe32.th32ProcessID;
      end;
    end;
    CloseHandle(hProcSnap);
  end;
end;



procedure TForm1.bPointer2Click(Sender: TObject);
var
  Address, InitialAddress, PID, Buff: Cardinal;
  Value: Cardinal;
  Access: THandle;
const
  OFFSET1: Cardinal = $0768;
  OFFSET2: Cardinal = $5560;
begin
  PID := GetProcessIdByName('popcapgame1.exe');
  Access := OpenProcess(PROCESS_ALL_ACCESS, False, PID);
  InitialAddress := Integer(GetModuleBaseAddress(PID, 'popcapgame1.exe')) + Integer($002A9EC0);
  Address := AddressOfMultiLevelPointer(Access, InitialAddress, [OFFSET1, OFFSET2]);
  ReadProcessMemory(Access, Ptr(Address), @Value, SizeOf(Value), Buff);
  Showmessage(IntToStr(Value));
end;


Both codes no works to change value. What's wrong with those codes?
I want to edit value from Multi-Level Pointer using WriteProcessMemory.
I need some help.

Thank you

Code:
  Address := Integer(GetModuleBaseAddress(ProcessID, 'popcapgame1.exe')) + Integer($002A9EC0);
  PHandle := OpenProcess(PROCESS_ALL_ACCESS, False, ProcessID);
  ReadProcessMemory(PHandle, Ptr(Address + $768), Addr(Buffer), 4, X);
  ReadProcessMemory(PHandle, Ptr(Buffer + $5560), Addr(Buffer), 4, X);
  WriteProcessMemory(PHandle, Ptr(Buffer), @NewValue, 1, X);

Your pointer path here is [[game.exe+002A9EC0+768]+5560]+0
The pointer path in CE is [[game.exe+002A9EC0]+768]+5560
Either add the offsets later or dereference the pointers earlier (more or less the same thing).

Thanks for your reply.

So I need to use the 1st code.

I tried to follow your instruction and change the code into like this:
Code:

Address := Integer(GetModuleBaseAddress(ProcessID, 'popcapgame1.exe')) + $002A9EC0 + $768;
  PHandle := OpenProcess(PROCESS_ALL_ACCESS, False, ProcessID);
  ReadProcessMemory(PHandle, Ptr(Address + $5560), Addr(Buffer), 4, X);
  ReadProcessMemory(PHandle, Ptr(Buffer), Addr(Buffer), 4, X);
  WriteProcessMemory(PHandle, Ptr(Buffer), @NewValue, 1, X);


is that correct?

But, still I got no result.

Salam

Code:
procedure WritePointer;
var
  finalAddress: NativeUInt;
begin
  //some code like ProcessID :=, PHandle :=, etc.

  finalAddress := GetModuleBaseAddress(ProcessID, 'popcapgame1.exe') + $2a9ec0;

  ReadProcessMemory(PHandle, Pointer(finalAddress), @finalAddress, 4, X);

  Inc(finalAddress, $768);

  ReadProcessMemory(PHandle, Pointer(finalAddress), @finalAddress, 4, X);

  Inc(finalAddress, $5560);

  WriteProcessMemory(PHandle, Pointer(finalAddress), @NewValue, 4, X);
end;

Of course I'd also advise you to check if all the functions returned successful ...

Now your pointer path is [[game.exe + 002A9EC0 + 768 + 5560] + 0] + 0

You're even worse off than you were before. It's clear you don't understand what pointers are, so you should study them before you try to use them.

At least look at this topic.

@hhhuut
Thank you. Your code really works!
So I go back to my problem and try figuring out why I got wrong result.
And finally, I get a good one now.

So the code should be like this:
Code:

Address := Integer(GetModuleBaseAddress(ProcessID, 'popcapgame1.exe')) + $002A9EC0;
ReadProcessMemory(PHandle, Ptr(Address), @Address, 4, X);
ReadProcessMemory(PHandle, Ptr(Address + $768), @Address, 4, X);
WriteProcessMemory(PHandle, Ptr(Address + $5560), @NewValue, SizeOf(NewValue), X);


Thank you so much @ParkourPenguin
Your guide is great.

Now it's solved and I want to try coding next step.

Thank you once again!!

Salam.
