Using ReplicantHook

#include <iostream>
#include "ReplicantHook.hpp"
#include <thread>
using namespace std;

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


/*This is a showcase program of the hook
* As NieR Replicant ver.1.22474487139 is a x64 program, you must compile this solution in x64.
