Logic game with sokoban elements for GNU Emacs.

Clone the repo and add the following lines to your .emacs.

(add-to-list 'load-path "/path/to/ducpel-dir")
(autoload 'ducpel "ducpel" nil t)

The package can be installed from MELPA or using quelpa like this:

(quelpa '(ducpel :fetcher github :repo "alezost/ducpel" :files ("*.el" "levels")))

Use M-x ducpel to start the game and the following keys to play:

• left/right/up/down – move a man;
• TAB/S-TAB – switch to the next/previous man;
• SPC – activate a special cell (exit or teleport);
• u – undo a move;

Key bindings for levels:

• R – restart current level (with prefix also reread a level file);
• N/P – go to the next/previous level;
• L – go to the specified level;
• F – load a level from file.

Key bindings for replaying:

• rc – replay current moves;
• rS – replay solution (each inbuilt level has a solution);
• rs – save current moves to a file;
• rf – replay saved moves from a file;

You will learn everything you need during playing the game.

TODO Write something here.

If you found a better solution than the default one, and especially if you created a level, you may make a pull request or open an issue.

Making new levels is a priority. artist-mode can be useful during building a map. A level file consists of 2 maps:

• The main map (titled with ; Map) defines:

  • @ – impassable cells (unbreakable walls);
  • # – breakable walls;
  • – empty cells;
  • floors:
    • . – simple floor,
    • E – exit,
    • T – teleport,
    • L – floor that can move left,
    • R – floor that can move right,
    • U – floor that can move up,
    • D – floor that can move down,
    • H – floor that can move horizontally (left and right),
    • V – floor that can move vertically (up and down),
    • M – floor that can move in any direction.

• The second map (titled with Objects) is used only to define the position of men and boxes:

  • p – inactive man;
  • P – active man;
  • boxes: b, e, t, l, r, u, d, h, v, m (the same meaning as for the floors above).

  Other characters in the object map are ignored.

Also a level should provide a solution (ducpel-moves-history variable contains the moves and it is the solution after you passed a level).

I thought it would be great to make a sokoban-like game where several men can move several boxes and boxes can be transformed into floors, so that you can build a path to the exit.

A big part of the game is the idea of moving cells (floors with arrows). It was taken from a non-free game "Metamorphs" (it was released only for Microsoft Windows around 2000).

The code of sokoban package was used hardly.

I just tried to make a unique name and stayed on this variant because it ends with "el" and it consists (almost) of 2 latin roots:

• duco, ducere, duxi, ductus – to lead;
• pello, pellere, pepuli, pulsus – one of the meanings is "to push".
