    players = length(player('all'));

    if (players != 0, (
        // use "player" if only 1 is online, else use plural "players"
        text = if (players == 1, 'player', 'players');

        dc_set_activity('playing', str('with %s %s', players, text));
        dc_set_status('online');
    ), (
        dc_set_activity('playing','with nobody');
