NAME

SDLx::FPS - a more convenient way to set a framerate

SYNOPSIS

 use SDLx::FPS;
 my $fps = SDLx::FPS->new(fps => 60);
 while(1) { # Main game loop
     # Do game related stuff

     $fps->delay;
 }

DESCRIPTION

SDLx::FPS simplifies the task of giving your game a framerate. Basically, it combines the methods of "SDL::GFX::Framerate" and "SDL::GFX::FPSManager" into a single module. Use it to delay the main loop to keep it at a specified framerate.

METHODS

new

 my $fps = SDLx::FPS->new( fps => 30 );

No arguments are required, if no "fps" is specified, the default FPS is 30.

set

 $fps->set($new_framerate);

Same as "SDL::GFX::Framerate::set". Set the new desired framerate.

get

Same as "SDL::GFX::Framerate::get". Get the currently set framerate.

delay

Same as "SDL::GFX::Framerate::delay". Generate a delay to accommodate 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 0 and the delay interpolation is reset.

framecount

Return the "framecount".

rateticks

Return the "rateticks".

lastticks

Return the "lastticks".

rate

Return the "rate".
