NAME

SDLx::Widget::Menu - create menus for your SDL apps easily

SYNOPSIS

Create a simple SDL menu for your game/app:

my $menu = SDLx::Widget::Menu->new->items(
               'New Game' => \&play,
               'Options'  => \&settings,
               'Quit'     => \&quit,
           );

Or customize it at will:

my $menu = SDLx::Widget::Menu->new(
               topleft      => [100, 120],
               font         => 'game/data/menu_font.ttf',
               font_size    => 20,
               font_color   => [255, 0, 0], # RGB (in this case, 'red')
               select_color => [0, 255, 0],
               change_sound => 'game/data/menu_select.ogg',
           )->items(
               'New Game' => \&play,
               'Options'  => \&settings,
               'Quit'     => \&quit,
           );

After that, all you have to do is make sure your menu object's hooks are called at the right time in your game loop:

# in the event loop
$menu->event_hook( $event );  # $event is a SDL::Event

# in the rendering loop
$menu->render( $screen );     # $screen is a SDL::Surface

DESCRIPTION

Main menus are a very common thing in games. They let the player choose between a new game, loading games, setting up controls, among lots of other stuff. This menu widget is meant to aid developers create menus quickly and easily, so they can concentrate in their game's logic rather than on such a repetitive task. Simple menus, easy. Complex menus, possible!
