NAME

6       SDL::GFX::Framerate - framerate calculating functions
7

CATEGORY

9       GFX
10

DESCRIPTION

12       The framerate functions are used to insert delays into the graphics
13       loop to maintain a constant framerate.
14

METHODS

16   init
17        use SDL;
18        use SDL::GFX::Framerate;
19        use SDL::GFX::FPSManager;
20
21        my $fps = SDL::GFX::FPSManager->new(0, 0, 0, 0);
22
23        SDL::GFX::Framerate::init($fps);
24
25       Initialize the framerate manager, set default framerate of 30Hz and
26       reset delay interpolation.
27
28   set
29        SDL::GFX::Framerate::set($fps, 60);
30
31       Sets the new desired framerate to 60 frames per second.
32
33   get
34        my $rate = SDL::GFX::Framerate::get($fps);
35
36       Get the currently set framerate of the manager.
37
38   delay
39        SDL::GFX::Framerate::delay($fps);
40
41       Generate a delay to accommodate the currently set framerate. Call once
42       in the graphics/rendering loop.  If the computer cannot keep up with
43       the rate (i.e. drawing too slow), the delay is zero and the delay
44       interpolation is reset.
