NAME

Algorithm::Easing::Circular - Calculate eased translations between two positive whole integer values over time

SYNOPSIS

use Algorithm::Easing;
use Algorithm::Easing::Circular;

# this example produces traditional 'circular' output;

my $translation = Algorithm::Easing::Circular->new;

# total time for eased translation as a real positive integer value
my $d = 2.5;

# begin
my $b = 0;

# change
my $c = 240;

# time passed in seconds as a real positive integer between each frame
my $frame_time = 0.0625;

my @p = [319,0];

for(my $t = 0; $t < 2.5; $t += 0.0625) {
    $p[1] = $translation->ease_out($t,$b,$c,$d)

    # plot
    ...;
}

METHODS

ease_none Usage :

Arguments : 
    t = time,
    b = begin,
    c = change,
    d = duration,
Return :
    p = position,
    
my $p = $obj->ease_none($t,$b,$c,$d);

This method is used for a linear translation between two positive real whole integers using a positive real integer as the parameter for time.

ease_in Usage :

Arguments : 
    t = time,
    b = begin,
    c = change,
    d = duration,
Return :
    p = position,
    
my $p = $obj->ease_in($t,$b,$c,$d);

This method is used to ease in between two positive real whole integers as an inward tween using a positive real integer as the parameter for time in a circular fashion.

ease_out Usage :

Arguments : 
    t = time,
    b = begin,
    c = change,
    d = duration,
Return :
    p = position,
    
my $p = $obj->ease_out($t,$b,$c,$d);

This method is used to ease out between two positive real whole integers as an inward tween using a positive real integer as the parameter for time in circular fashion.

ease_both Usage :

Arguments : 
    t = time,
    b = begin,
    c = change,
    d = duration,
Return :
    p = position,
    
my $p = $obj->ease_both($t,$b,$c,$d);

This method is used to ease both in then out between two positive real whole integers as an inward tween using a positive real integer as the parameter for time in circular fashion.
