MacMines™ is a very simple program based on simple logic. Upon choosing the difficulty level, you are presented with a grid of squares. Your objective is to determine which of those squares contain mines and which do not.
To do this, begin by clicking on any square in the grid. If you are lucky, it will not contain a mine, but will instead change to either a number or a blank square. This number or empty square tells you how many mines are in the immediately surrounding eight squares (six if you clicked on a side square, or three if you clicked on a corner square). If the square is empty, it means that there are NO mines in the surrounding squares. You then continue clicking on squares using the numbers they provide, trying to click on all safe squares and avoiding all squares with mines. To aid you in remembering which squares have mines, you can hold down the Command key and click on a square that you think contains a mine. This will put a "flag" on that square, and from then on you cannot click on the square accidentally (the game just won't let you!) If you think you "flagged" a square incorrectly, simply Command-Click it again, and the flag will disappear. At the bottom of the game board, you will see an icon for a watch and a mine. The timer on the left starts when you click on the first square, and stops ONLY when you die or win... It will NOT pause if MacMines is put in the background (no cheating now :), but you can 'pause' the game if necessary, although the board is hidden until you 'unpause.' The mine icon and associated number indicate how many mines you have left to flag. Note: the number is based on the number of FLAGS you have set -- this counter doesn't care if the flags are right or not!
The game ends when you either reveal a mine, or have found ALL the safe squares AND have flagged ALL the mine squares. If you reveal a mine, the program will "explode," and then show you where all the mines are. Any squares that you marked as mines that are not really mines will have a yellow X on them. If you want to continue playing MacMines™, you have to start a new game. If you win, and your score is fast enough, you will be asked for your name. Your name and time will be placed in the appropriate Roster for the level you completed. You can then start a new game, or quit.
This game was written in THINK Pascal 4.0.?, primarily between the hours of10:00pm and 2:00am during early February, 1993. I missed my "Minesweeper™" for Windows in the PC world, and so decided to implement my own version for the Macintosh. Many thanx to the readers of 'comp.sys.mac.programmer' for their answers to my late-night questions on random number generators, memory allocation, and dialog boxes! Additional thanx go to Lim Unlimited for Lloyd Lim's "Default CDEF," a very nice CDEF that puts outlines around the default button in a dialog box. (The Default CDEF docs are included in the official release of this package, and you can extract the CDEF using ResEdit -- its the only CDEF in MacMines™.)
MacMines™ has been written and tested on a Mac IIsi under System 7.1, and tested on a Mac LC II and SE/30 using System 7.0.1+Tuneup 1.1.1. If I get around to it, it will eventually get tested on the Mac Classics and IIci's in Cornell's various labs, but right now (Feb 6, 11:14pm) its just too damn cold to walk over there! I have run it under B&W, 4, 16, and 256 colors, with no problems (it looks MUCH better in 256) and it seems to background with no problems. However, I take NO RESPONSIBILITY for any problems occurring due to the use of MacMines™. If it doesn't work, don't use it!
You can use MacMines™ for as long as you like, but if you find yourself using it extensively (read "are you addicted yet?"), please send me a postcard! I'd like to see how far this thing gets, and if I get enough positive response, I may even implement some other ideas if people have interesting ones. You can reach me at the addresses below!
I'm a (almost) 19-yr-old freshman at Cornell University in Ithaca, NY, and probably will be majoring in Computer Science. I program mostly in Pascal, although I'm working on C and Unix. No matter what the quote below says, I do use the MS-DOS world for occassional programming (look for a VGA game from 'Schwiebert and Russo', hopefully to be done by the end of this semester.
enjoy!! -- Erik --

Also, if you do write to me at my home address, please indicate on the outside of the envelope that my parents are to forward it to me at college (note: my parents, not the Post Office!) Again, internet is probably the fastest, and i can ALMOST guarantee a response!)
