Problem of Reading PlayerGUID

[Summer414]

HELP! I tried to read PlayerGUID with ReadProcessMemory in cpp. Sometimes it returned TRUE but the PlayerGUID is 0. And sometimes it returned FALSE with error code 299. It's a very simple program.

#include <stdlib.h>
#include <stdint.h>
#include <Windows.h>

static const ULONG PlayerGUID = 0x267D640;
int main(int argc, char* argv[])
{
	HWND hWnd = FindWindow(NULL, "Wow.exe");
	if (hWnd) {
		DWORD ProcessID;
		GetWindowThreadProcessId(hWnd, &ProcessID);

		HANDLE hProcess = OpenProcess(PROCESS_QUERY_INFORMATION | PROCESS_VM_READ | PROCESS_VM_OPERATION, false, ProcessID);

		SIZE_T Bytes = 0;
		uint64_t GUID;
		BOOL Ret = ReadProcessMemory(hProcess, (LPVOID)PlayerGUID, &GUID, sizeof(GUID),  &Bytes);
		if (!Ret) {
			DWORD dwError = GetLastError();
		}
		CloseHandle(hProcess);
	}
	return 0;
}

This is my cpp program. Ret is TRUE and the GUID is 0. Did I do something wrong?

I tried several times. Sometimes I got invalid GUIDs. For example, the GUID from ReadProcessMemory was 0x267D640. But what I got from /run UnitGUID("Player") is Player-4789-01764FA4.

You need to rebase the PlayerGUID pointer to the current running wow binary BaseAddress.

Also if you are working with the retail binary the GUID is Int128 not 64 bit. If you are working with Classic it should be 64bit.

Heh, 64 bit? So there is no need in 128 bit?

GUIDs are 128 bits on classic as well.

correct both 128 live and classic i use my bot on both i just have it use offsets based on what version and dbcs the same as well seems for most of them etc

Yes, you're right. I should rebase playerGUID to BaseAddress~I'm working with wow classic. Thanks a lot !

I'm working with wow classic~I'm not sure it is 64-bit or 128-bit.

I do not work with classic, but if Charles420 says it is 128 bit on classic go with that.
