Using NieRHook

#include <Windows.h>
#include <TlHelp32.h>
#include <iostream>
#include <thread>
#include "NierHook.hpp"
using namespace std;

//Function used to exit the program
void ENDPressed(NieRHook* hook) {
	while (true) {
		if (GetKeyState(VK_END) & 0x8000) //END button pressed
		{
			//Disable cheats before exiting
			hook->InfiniteDoubleJump(false);
			hook->IgnoreUpgradeMaterials(false);
			//Stop hook
			hook->stop();
			return;//exit function
		}
	}
}

/*This is a showcase program of the hook
* As NieR:Automata is a x64 program, you must compile this solution in x64.
