24 ;; Commentary: This is a complete reimplementation of the classical
|
|
|
25 ;; mine searching game known from various OS/GUIs under names like
|
|
|
26 ;; xmine, minesweeper etc.
|
|
|
27
|
|
|
28 ;; The idea to implement this in elisp is from
|
|
|
29 ;; Jacques Duthen <duthen@cegelec-red.fr>,
|
|
|
30 ;; the author of the original mine game for GNU Emacs. This version
|
|
|
31 ;; has to the best of my knowledge no code in common with his version,
|
|
|
32 ;; but cudos go to him for first starting this...
|
|
|
33 ;;
|
|
|
34 ;; I mainly wrote this as an example how graphics handling in XEmacs
|
|
|
35 ;; is possible. I think I did it the right way, using an extension to
|
|
|
36 ;; the annotation mechanism and via extensive use of `slots' (realized
|
|
|
37 ;; as properties of extents) to hold the data in the object itself.
|
|
|
38 ;; (Of course this is not true. The keyboard handling is controlled from
|
|
|
39 ;; the "outside" of the objects. But at one time during development
|
|
|
40 ;; before hacking the keyboard controls the code really _was_ nice...
|
|
|
41 ;; now it's a bad messing with slots and controls from the outside)

562 The rules are quite easy: You start by unhiding (random) tiles. An unhidden
|
|
|
563 tile showing a number tells you something about the number of mines in it's
|
|
|
564 neighborhood, where the neighborhood are all 8 tiles (or less if it's
|
|
|
565 at a border) around the tile.
|
|
|
566
|
|
|
567 E.g. a \"1\" shows you that there is only one mine in the neighborhood of
|
|
|
568 this tile. Empty tiles have no mines around them, and empty tiles in
|
|
|
569 the neighborhood of another empty tile are all automatically unhidden
|
|
|
570 if you unhide one of them. You need to find a strategy to use the
|
|
|
571 information you have from the numbers to \"flag\" the tiles with mines
|
|
|
572 under them and unhide all other tiles. If you correctly made this
|
|
|
573 without accidently unhiding a mine, you've won.
|
|
|
574
|
|
|
575 If you are sure you have correctly flagged all mines around a unhidden tile,
|
|
|
576 you can use Button-2 or \\[xmine-key-action2] on it to unhide all it's
|
|
|
577 neighbors. But beware: If you made a mistake by flagging the wrong mines,
|
|
|
578 you'll blow up!
