# SDL::GFX::Framerate(3pm)

framerate calculating functions

## 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.
