Um pouco mais de controle

Manipulando Eventos #1 use SDL::Event; sub on_event { my $event = shift; if ($event>type == SDL_QUIT) { return 0; } return 1; } $app>add_event_handler( &on_event );

Exibindo... algo :) use SDL::Rect; my $rect = SDL::Rect>new(10,10,10,10); $app>add_show_handler( sub { $app>draw_rect([0,0,$app>w,$app>h],0xFFFFFFFF); $app>draw_rect($rect, 0xFF0000FF); $app>update; });

Manipulando Eventos #2 sub on_event { my $event = shift; if ($event>type == SDL_QUIT) { return 0; } return 1; }

Manipulando Eventos #2 sub on_event { my $event = shift; if ($event>type == SDL_QUIT) { return 0; } elsif ($event>type == SDL_KEYDOWN) { given ($event>key_sym) { when (SDLK_LEFT ) { $rect>x( $rect>x 2 ) }; when (SDLK_RIGHT) { $rect>x( $rect>x + 2 ) }; when (SDLK_UP ) { $rect>y( $rect>y 2 ) }; when (SDLK_DOWN ) { $rect>y( $rect>y + 2 ) }; }; } return 1; }
