Question

I have a problem with programming movement using C++ and Ncurses.
I’m programming a pacman and the main problem is, that I just want last pressed key in time period.

When I use usleep, it saves every key pressed during sleeping and then it’s working with that in the order.

Thanks for ideas.

Answer 1

Are you in no-delay mode? If so, this might work:

usleep(your_delay);
last_key = ERR;
while ( (key=getch()) != ERR ) {
  last_key = key;
}
// "last_key" now holds most recent key, if there was one, else ERR
