NAME

SDL::GFX::Framerate - framerate calculating functions

CONTENTS

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.
