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.
