NAME ^

tetris - A tetris game

SYNOPSIS ^

perl tetris.pl

CONFIGURATION ^

The configuration file should be the file with name ".tetris" under HOME directory. Another option is using Tetris/Config.pm in any directory of @INC.

Here is an example of configuration: # -*- perl -*- %Config = ( %Config, 'start_level' => 3, 'down_step' => 2, 'keybindings' => { %{$Config{keybindings}}, ord('j') => \&move_left, ord('l') => \&move_right, ord('k') => \&rotate, ord('n') => \&new_game, } ); push @$shapes, shape_from_string(<<SHAPE); 0 0 8 0 0 8 0 0 0 8 8 8 0 0 0 8 0 0 8 0 0 8 8 8 0 0 8 0 0 8 8 8 0 8 8 8 0 8 0 0 0 0 8 0 0 0 0 8 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 SHAPE

    push @$shapes, shape_from_string(<<SHAPE);
    0 0 9 0   0 0 0 0   0 0 0 0   0 0 9 0
    0 0 9 9   0 0 9 9   0 9 9 0   0 9 9 0
    0 0 0 0   0 0 9 0   0 0 9 0   0 0 0 0
    0 0 0 0   0 0 0 0   0 0 0 0   0 0 0 0
    SHAPE

The key specification can get from this script:

    use Gtk2::Gdk::Keysyms;
    use Glib qw/TRUE FALSE/;
    use Gtk2 -init;
    
    my $window = Gtk2::Window->new ('toplevel');
    $window->signal_connect (delete_event => sub { Gtk2->main_quit });
    $window->signal_connect('key-press-event' => \&show_key);
        
        my $label = Gtk2::Label->new();
        $label->set_markup("<span foreground=\"blue\" size=\"x-large\">Type something on the keyboard!</span>");
        
    $window->add ($label);
    $window->show_all;
    $window->set_position ('center-always');
    
    Gtk2->main;

    sub show_key {
        my ($widget,$event,$parameter)= @_;
        my $key_nr = $event->keyval();
        foreach my $key (keys %Gtk2::Gdk::Keysyms) {
                my $key_compare = $Gtk2::Gdk::Keysyms{$key};
                if ($key_compare == $key_nr) {
                print "'$key' => $key_nr,\n";
            }
        }
        return FALSE;
    }

Code to run after the GUI setup, add to code ref $after_load_function.
