NAME

  UAV::Pilot::ARDrone::SDLNavOutput

SYNOPSIS

  my $condvar = AnyEvent->condvar;
  my $events = UAV::Pilot::Events->new({
      condvar => $condvar,
  });
  
  my $window = UAV::Pilot::SDL::Window->new;
  my $sdl_nav = UAV::Pilot::ARDrone::SDLNavOutput->new({
      driver => UAV::Pilot::ARDrone::Driver->new( ... ),
      window => $window,
  });
  $events->register( $sdl_nav );

DESCRIPTION

Graphically renders a UAV::Pilot::ARDrone::NavPacket using SDL.

It does the UAV::Pilot::EventHandler role, and thus can be processed by UAV::Pilot::Events. It's recommended to also add the UAV::Pilot::SDL::Events handler to the events object, as that will take care of the SDL_QUIT events. Without that, there's no way to stop the process other than kill -9.

METHODS

new

  new({
      feeder => ...
  })

Constructor. The param feeder takes a UAV::Pilot::SDL::NavFeeder object.
