Also. Do a google search for GetAsyncKeyState

#include <iostream>
#include <windows.h>

using namespace std;

int main()
  {
  HANDLE hstdin = GetStdHandle( STD_INPUT_HANDLE );
  while (WaitForSingleObject( hstdin, 150 ) == WAIT_TIMEOUT)
    {
    cout << "Press the 'any' key..." << endl;
    }
  FlushConsoleInputBuffer( hstdin );
  cout << "Thanks!" << endl;
  return 0;
  }

If you are on Linux/Unix, let me know. You can also check out the NCurses library.

Good luck!

here is my code i tried GetAsyncKeyState but it happens too fast

so ill explain how my program works it uses a timer and the power builds up based on seconds so it needs to be in a constant loop to keep my screen updated

once a player has enough power you can preform a move

is there a command where it reads the key when the finger leaves the keyboard

Thanks

If the state of the key is acceptable with GetAsyncKeyState(), just set a timer and use GetTickCount(); Then you won't accept another power up for Xms.

thanks

how do i use GetAsyncKeyState with hexadecimals
Zaita (2770)
Put 0x infront of the number to make it a hex.
