I'm trying to use ncurses to create a game. I set it so that the character moves by arrow key input, but if I hold the arrow key for a while and then let go the character will keep moving for a while before stopping.
These are my initializations:
initscr();
start_color();
cbreak();
noecho();
nodelay(stdscr,TRUE);
keypad(stdscr, TRUE);
This is my main loop:
while(1) {
...
if (key == (char)27) {
break;
}
else if (key == KEY_DOWN) {
key = 0;
player->advance(0, 1);
}
else if (key == KEY_UP) {
key = 0;
player->advance(0, -1);
}
else if (key == KEY_LEFT) {
key = 0;
player->advance(-1, 0);
}
else if (key == KEY_RIGHT) {
key = 0;
player->advance(1, 0);
}
else {
key = getch();
}
std::this_thread::sleep_for(std::chrono::milliseconds {1000/30});
}
I'm using the sleep_for because I noticed that if I use timeout then the framrate changes if I'm pressing a key. Using sleep_for creates a consistent framerate, but input is somehow "sticky" as I explained. I need to fix this somehow. Either get a consistent framrate using timeout, or "un-stick" the input when using sleep_for.
player->advance(int, int) moves the player one step in the specified direction. Direction is specified as change in x and change in y to be applied to the current position.
