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 accomodate currently set framerate. Call once in thegraphics/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.
