I'd like to know why my little external hack is not working

[eyalolgadol1]

#include <iostream>
#include <Windows.h>
using namespace std;

int main()
{
DWORD pid;
DWORD playerHealth = 0x1DFE9F5B680;
int value = 0;

HWND hwnd = FindWindowA(0, "Grand Theft Auto V");
if (hwnd == NULL)
{
cout << "Cannot find window" << endl;
}

GetWindowThreadProcessId(hwnd, &pid);
HANDLE handle = OpenProcess(PROCESS_ALL_ACCESS, FALSE, pid);

if (GetAsyncKeyState(VK_SPACE))
{
WriteProcessMemory(hwnd, (LPVOID)playerHealth, &value, sizeof(value), 0);
}

}


this is a little external hack in c++ i made.
the address in question works when i change it through cheat engine, but when i compile the code and press space, it doesn't work.
this is a console application.
the address is a dynamic address ,but i have not closed the game yet and it works through cheat engine, so it should work here too.

I think this:

  DWORD playerHealth = 0x1DFE9F5B680;

is a non-static addr. So if you are restarting your game and trying to write at this addr, it's not working.
Otherwise, do you get the current health value when you try to read this address?
