NAME

Games::ABC_Path::MicrosoftRand - a pseudo-random number generator compatible with Visual C.

VERSION

Version 0.2.0

SYNOPSIS

use Games::ABC_Path::MicrosoftRand;

my $randomizer = Games::ABC_Path::MicrosoftRand->new(seed => 24);

my $random_digit = $randomizer->rand_max(10);

DESCRIPTION

This is a random number generator use by Games::ABC_Path::Generator, which emulates the one found in Microsoft's Visual C++. It was utilised here, out of familiarity and accessibility, because it is commonly used to generate Freecell layouts in the Freecell world (see http://en.wikipedia.org/wiki/FreeCell_%28Windows%29 ).

SUBROUTINES/METHODS

new

The constructor. Accepts a numeric seed as an argument.

my $randomizer = Games::ABC_Path::MicrosoftRand->new(seed => 1);

$randomizer->rand()

Returns a random integer from 0 up to 0x7fff - 1.

my $n = $randomizer->rand()

$randomizer->max_rand($max)

Returns a random integer in the range 0 to ($max-1).

my $n = $randomizer->max_rand($max);
# $n is now between 0 and $max - 1.

$randomizer->seed($seed)

Can be used to re-assign the seed of the randomizer (though not recommended).

my $array_ref = $randomizer->shuffle(\@array)

Shuffles the array reference of the first argument, destroys it and returns it. This is using the fisher-yates shuffle.
