function RPM4Byte(Addr: DWORD): DWORD;
var
Value: DWORD;
begin
ReadProcessMemory(HW, Pointer(Addr), @Value, SizeOf(Value), iRead);
Result := Value;
end;
DWORD RPM4Byte(DWORD addr)
{
HANDLE hProcess = GetModuleHandle(NULL);
DWORD value;
ReadProcessMemory(hProcess, (LPVOID)addr, &value, sizeof(value), NULL);
return value;
}
I'm making dll game hack
This is Delphi source
so I make it to c++
but It doesn't work
Why use ReadProcessMemory?
After playing the game, the pointer is not correct so it crashes.

If you are injected into the process, then you can just directly read from the address using pointer casting. Such as:

[comm3451]

I made it like this
DWORD RPM4Byte(DWORD addr)
{
HWND hwnd = FindWindowA(NULL, "KartRider Client");
if(hwnd == NULL)
{
printf("error");
return 1;
}else
{
DWORD procID;
GetWindowThreadProcessId(hwnd, &procID);
HANDLE hProcess = OpenProcess(PROCESS_ALL_ACCESS, FALSE, procID);
DWORD value;
ReadProcessMemory(hProcess, (LPVOID)addr, &value, sizeof(value), NULL);
return value;
}
}
and
DWORD FindRanking()
{
try
{
DWORD addr = 0x00C7BFAC;
addr = RPM4Byte(addr) + 0x18;
addr = RPM4Byte(addr) + 0xdc;
addr = RPM4Byte(addr) + 0x1f0;
addr = RPM4Byte(addr) + 0;
addr = RPM4Byte(addr) + 0x1cc;
return addr;
}catch(int i)
{

}

DWORD pt = FindRanking()
printf("%d",pt);
I used it but It says 405550497

I'd really suggest learning what you're doing first. There's a handful of problems with that code. Just copy-pasting stuff together isn't really going to teach you anything. You're creating various types of leaks with what you're doing as is.

DWORD value = NULL;
Right?
btw I'm making racing game hack
Its name is "KartRider"
and I have hack Delphi Source
I want to change It to c++ dll so I making it
DWORD addr = 0x00C7BFAC;
addr = RPM4Byte(addr) + 0x18;
addr = RPM4Byte(addr) + 0xdc;
addr = RPM4Byte(addr) + 0x1f0;
addr = RPM4Byte(addr) + 0;
addr = RPM4Byte(addr) + 0x1cc;
addr = RPM4Byte(addr);
return addr;
This is the source for ranking
And Why I don't use like this?
auto addr = 0x1234FFFF;
auto value = *(uint32_t*)addr;
because after one game is over, when I try to play next game, the value is not correct, so it crash and Delphi source use ReadProcessMemory and WriteProcessMemory.
anyway This is the delphi source.
