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.
