NAME

SDL::GFX::Framerate - framerate calculating functions

CATEGORY

GFX

DESCRIPTION

The framerate functions are used to insert delays into the graphics loop to maintain a constant framerate.

METHODS

init

            

              
              
use SDL;
use SDL::GFX::Framerate;
use SDL::GFX::FPSManager;
my $fps = SDL::GFX::FPSManager->new(0, 0, 0, 0);
SDL::GFX::Framerate::init($fps);
            
          

Initialize the framerate manager, set default framerate of 30Hz and reset delay interpolation.

set

            

              
              
SDL::GFX::Framerate::set($fps, 60);
            
          

Sets the new desired framerate to 60 frames per second.

get

            

              
              
my $rate = SDL::GFX::Framerate::get($fps);
            
          

Get the currently set framerate of the manager.

delay

            

              
              
SDL::GFX::Framerate::delay($fps);
            
          

Generate a delay to accommodate the currently set framerate. Call once in the graphics/rendering loop. If the computer cannot keep up with the rate (i.e. drawing too slow), the delay is zero and the delay interpolation is reset.
