NAME ^

Games::Sokoban - load/transform/save sokoban levels in various formats

SYNOPSIS ^

 use Games::Sokoban;

DESCRIPTION ^

I needed something like this quickly - if you need better docs, you have to ask.

Supports xsb (text), rle, sokevo and a small "binpack" format for input and output and can normalise levels as well as calculate unique IDs.

$level = new Games::Sokoban [format => "text|rle|binpack"], [data => "###..."]
$level = new_from_file Games::Sokoban $path[, $format]
$level->data ([$new_data, [$new_data_format]])

Sets the level from the given data.

$text = $level->as_text
$binary = $level->as_binpack

Binpack is a very compact binary format (usually 17% of the size of an xsb file), that is still reasonably easy to encode/decode.

It only tries to store simplified levels with full fidelity - other levels can be slightly changed outside the playable area.

@lines = $level->as_lines
$line = $level->as_rle

http://www.sokobano.de/wiki/index.php?title=Level_format

($x, $y) = $level->start

Returns (0-based) starting coordinate.

$level->hflip

Mirror horizontally.

$level->vflip

Mirror vertically.

$level->transpose

Transpose level (mirror at top-left/bottom-right diagonal).

$level->rotate_90

Rotate by 90 degrees clockwise.

$level->rotate_180

Rotate by 180 degrees clockwise.

$id = $level->simplify

Detect playable area, crop to smallest size.

$id = $level->normalise

Simplifies the level map and calculates/returns its identity code. . http://www.sourcecode.se/sokoban/level_id.php, assume uppercase and hex.

$levels = Games::Sokoban::load_sokevo $path

Loads a sokevo snapshot/history file and returns all contained levels as Games::Sokoban objects in an arrayref.
