|
|
32 ;; The object of this classical game is to locate the hidden mines.
|
|
|
33 ;; To do this, you hit the squares on the game board that do not
|
|
|
34 ;; contain mines, and you mark the squares that do contain mines.
|
|
|
35
|
|
|
36 ;; The number of hidden mines remaining in the mine field is indicated
|
|
|
37 ;; inside the buffer. Every time you mark a square as a mine, this
|
|
|
38 ;; number decreases by one, even if you incorrectly mark a square.
|
|
|
39
|
|
|
40 ;; To hit a square: Point to the square, and click the left button.
|
|
28
|
41 ;; If the square is a mine, you lose.
|
|
22
|
42 ;; If the square isn't a mine, a number appears, which represents
|
|
|
43 ;; the number of mines in the surrounding eight squares.
|
|
|
44
|
|
|
45 ;; To mark a square as a mine: Point to the square, and click
|
|
|
46 ;; the right button.
|
|
|
47
|
|
|
48 ;; To play Mine, compile it if you want, load it, and type `M-x mine'.
|
|
|
49
|
|
|
50 ;; To get help and doc, see the functions `mine' and `mine-help'
|
|
|
51 ;; (ie. type `?' in the *Mine* buffer or type `C-h f mine')
|
|
|
52
|
|
|
53 ;; This module has been developed and tested with GNU Emacs 19.31.1,
|
|
|
54 ;; but it should run with any GNU Emacs 19.* (at least with versions
|
|
|
55 ;; superior to 19.31).
|
|
|
56
|
|
|
57 ;; This module has not been tested (yet) with XEmacs. It may or may
|
|
|
58 ;; not run (can anybody tell me?).
|
|
|
59

|
60 ;; Send any comment or bug report (do you expect to find any? ;-) to me:

62
|

|
|
|
66 ;; Fix bug: (void-function unless), add minimal support for xemacs.
|
|
|
67 ;; (mine-xemacs-p): Added.
|
|
|
68 ;; (event-point): New function.
|
|
|
69 ;; (mine-mouse-hit, mine-mouse-mark): Use (interactive "@e") and `event-point'
|

70 ;; (mine-init-mode-map): Support xemacs mouse binding.
|
|
|
71 ;; (mine-make-face): Support xemacs get-face.
|
|
|
72 ;; (mine-goto): Support `auto-show-make-point-visible' as well as

320 What is Mine?\\<mine-mode-map>
|
|
|
321
|
|
|
322 Mine is a classical game of hide and seek played on a rectangular grid
|
|
|
323 containing `mine-xmax' by `mine-ymax' squares (the mine field).
|
|
|
324
|
|
|
325 Your opponent (Emacs, in this case) has hidden several mines within
|
|
|
326 this field. The object of the game is to find every hidden mine.
|
|
|
327
|
|
|
328 When you're sure a square does NOT contain a mine, you can hit it:
|
|
|
329 move the mouse over the square and press `\\[mine-mouse-hit]' or
|
|
|
330 move the cursor with the usual keys and press `\\[mine-hit-curpoint]'.
|
|
|
331
|
|
28
|
332 If the square is a mine, you lose.
|
|
22
|
333 If the square isn't a mine, a number appears which represents
|
|
|
334 the number of mines in the surrounding eight squares.
|
|
|
335

336 When you think a square DOES contain a mine, you can mark it:
|
|
|
337 move the mouse over the square and press `\\[mine-mouse-mark]' or
|
|
|
338 move the cursor with the usual keys and press `\\[mine-mark-curpoint]'.
|
|
|
339
|
|
|
340 The number of hidden mines remaining in the mine field is indicated
|
|
|
341 inside the buffer. Every time you mark a square as a mine, this
|
|
|
342 number decreases by one, even if you incorrectly mark a square.
|
|
|
343
|
|
|
344 If `mine-torus' is non-nil (the default), the Mine game is played over
|
|
|
345 a periodic field (like a torus). Each mine is hidden periodically
|
|
|
346 over the mine board `mine-nb-tiles-x' times in the x direction and
|
|
|
347 `mine-nb-tiles-y' times in the y direction.
|
|
|
348
|
|
|
349 If `mine-colorp' is non-nil (the default, if the system allows it),
|
|
|
350 the game is displayed with colors. The colors can be chosen with the
|
|
|
351 variable `mine-colors'.
|
|
|
352
|
|
|
353 If the redisplay is not fast enough, increase `mine-level'. If you
|
|
|
354 want to see a smoother (slower) redisplay, decrease `mine-level',
|
|
|
355 `mine-count1-max' and `mine-count2-max'.
|
|
|
356
|
|
|
357 You can get help on `mine-mode' and its key bindings by pressing `\\[mine-help]'
|
|
|
358 while in the *Mine* buffer.
