29 ;; Commentary: This is a complete reimplementation of the classical
|
|
30 ;; mine searching game known from various OS/GUIs under names like
|
|
31 ;; xmine, minesweeper etc.
|
|
32
|
|
33 ;; The idea to implement this in elisp is from
|
|
34 ;; Jacques Duthen <duthen@cegelec-red.fr>,
|
|
35 ;; the author of the original mine game for GNU Emacs. This version
|
|
36 ;; has to the best of my knowledge no code in common with his version,
|
|
37 ;; but cudos go to him for first starting this...
|
|
38 ;;
|
|
39 ;; I mainly wrote this as an example how graphics handling in XEmacs
|
|
40 ;; is possible. I think I did it the right way, using an extension to
|
|
41 ;; the annotation mechanism and via extensive use of `slots' (realized
|
|
42 ;; as properties of extents) to hold the data in the object itself.
|
|
43 ;; (Of course this is not true. The keyboard handling is controlled from
|
|
44 ;; the "outside" of the objects. But at one time during development
|
|
45 ;; before hacking the keyboard controls the code really _was_ nice...
|
|
46 ;; now it's a bad messing with slots and controls from the outside)
|
|
47 ;;
|
|
48 ;; Code:
|
|
49 ;;
|
|
50 ;;; First of all we'll define the needed varibles.

|
|
487 tile showing a number tells you something about the number of mines in it's
|
|
488 neighborhood, where the neighborhood are all 8 tiles (or less if it's
|
|
489 at a border) around the tile.
|
|
490
|
|
491 E.g. a \"1\" shows you that there is only one mine in the neighborhood of
|
|
492 this tile. Empty tiles have no mines around them, and empty tiles in
|
|
493 the neighborhood of another empty tile are all automatically unhidden
|
|
494 if you unhide one of them. You need to find a strategy to use the
|
|
495 information you have from the numbers to \"flag\" the tiles with mines
|
|
496 under them and unhide all other tiles. If you correctly made this
|
|
497 without accidently unhiding a mine, you've won.
|
|
498
|
|
499 If you are sure you have correctly flagged all mines around a unhidden tile,
|
|
500 you can use Button-2 or \\[xmine-key-action2] on it to unhide all it's
|
|
501 neighbors. But beware: If you made a mistake by flagging the wrong mines,
|
|
502 you'll blow up!
