==============
GamesPack v1.3
==============
This package contains a collection of simple games using a VGA mode
(640x480x16) and (optionally, but highly recommended) a mouse.
------------
Requirements
------------
* svgalib (tested with version 1.24).
Some distributions (e.g. slackware) have separated the svgalib
shared libraries from the rest of the distribution. In these cases,
ensure that both packages are installed.
------------
Installation
------------
* Edit the Makefile, setting/changing USEMOUSEFUNCS, NOMOUSE,
MOUSEDEFAULTRATE, USEGETPIXEL, BINDIR, LIBDIR and PREFIX, if necessary.
- USEMOUSEFUNCS should be set to use the mouse_ functions, rather than
vga_setmousesupport(). This allows console switching for svgalib
versions earlier than 1.20. If problems are encountered with
console switching, undefine this. You should not need to define
it if you are using svgalib 1.20 or later.
- NOMOUSE removes mouse support.
- MOUSEDEFAULTRATE changes the mouse sampling rate from the default, if
USEMOUSEFUNCS is also defined.
- The PREFIX is to avoid clashes with other programs with the same
name. I suggest using vga_ or nothing as the prefix.
- USEGETPIXEL can be set to use the vga_getpixel() function instead of
maintaining a shadow copy of the screen. Thus, it will result in less
memory being used. For svgalib v1.24 and earlier this should not be
used, because it doesn't work properly. Hopefully this will work in a
future version of svgalib. If USEGETPIXEL is defined, screen redrawing
is not available. This is probably not an issue for most people.
However, I'll look into this if/when vga_getpixel() works.
* Type 'make'.
* As root, type 'make install'.

Thanks
------
* Keith Pomakis <kppomaki@jeeves.uwaterloo.ca> for writing the
Connect-4 algorithm and putting it into the public domain. See the
directory c4 for more information.
* Bennett Todd <bet@std.sbi.com> for writing the Othello algorithm and
posting it to alt.sources. See the directory othello for more
information.
* Harm Hanemaayer <hhanemaa@cs.ruu.nl>,
Michael Weller <eowmob@exp-math.uni-essen.de>,
and other contributors for svgalib.
* Rob Malouf <malouf@csli.stanford.edu> for (unknowingly) contributing
the font from dvgt (a very nice svgalib dvi viewer).
* Adam Jenkins <apj@twain.oit.umass.edu> for reporting the keyboard
checking bug in connectN.
* Laszlo <root@light-house.gts.org> for reporting the mouse pointer
display bug and suggesting I use less CPU time.
* Thomas Roettgers <tom@bangor.franken.de> for prompting the
improvement in the mines losing end of game scenario, to provide
more information.
-----
Notes
-----
* In addition to the mouse, there are keyboard shortcuts for the grey
buttons presented on the right of the screen: n for New Game, q for Quit.
The cursor keys will move the pointer and the return key performs the
same function as the mouse button. These allow you to play, even if you
don't have a mouse. As a bonus, the interrupt character (often ^C) also
works.
* Console switching is enabled using the usual mechanism (Alt-Fn) if
the programs were compiled with either USEMOUSEFUNCS or NOMOUSE
defined, or if svgalib 1.20 or later is used.
* Screen redrawing is available using either the r key, or ^L. This
feature may be useful if the screen gets corrupted as a result of console
switching.
----------
Known Bugs
----------
* None. 8-)
----------------------
Potential Improvements
----------------------
The following will invalidate compatibility with older versions of
svgalib:
* Investigate keyboard_ functions so we can use select() rather than
polling the keyboard/mouse (this would require at least svgalib
1.20, assuming it works).

Game Notes
==========
---------
Connect-N
---------
This is the standard game of Connect-4 with additional parameters to
allow the player to play Connect-3 to Connect-10 on boards varying in
size from 4x3 to 21x19.
The computer player was very well written by Keith Pomakis
<kppomaki@jeeves.uwaterloo.ca>, the interface by myself. Keith's
original distribution can be found in the subdirectory c4. It was
used unmodified.
Moves can be made by clicking the left mouse button (or return key)
anywhere in the column you want to put a block in. If the board width
is less than 10, typing a number from 1 to 9 puts a block in that
column.
The intelligence of the computer may be set to any number between 1
and 10, the default is 5. The more intelligent it is (higher
numbers), the longer it takes to make a move. The board size has a
similar effect.
At the default intelligence on the default board size, it takes an
acceptable period of time to think of its moves (on my 486DX33), at 3
it's really quick, at 10 it takes "forever". On a 386 you may want
the default to be -i4, on a faster 486, perhaps -i6. Try them and
find out.
While the computer is thinking, the only button which works is the
quit button.
Some ways of playing the game:
$ vga_connectN # Connect-4 on a 7x6 board
$ vga_connectN -i3 -r # decide moves quickly, reverse player colours
$ vga_connectN -n5 -w9 -h8 # Connect-5 on a 9x8 board
$ vga_connectN -n3 -w5 -h4 -c # Connect-3 on a 5x4 board, computer starts
I suggest making aliases for your favourite incantations (connect4,
connect5, etc).
ChangeLog:
1.0 9 Jul 1994 First Linux version completed
1.1 26 Jan 1995 Keyboard checking bug fixed
Mouse pointer display bug fixed
Less CPU used waiting for user input
1.2 18 Feb 1995 Added vga_getpixel() support to vga16.c
1.3 26 Feb 1995 Added screen redrawing
-------
Othello
-------
This is the standard game of Othello.
The computer player was written by Bennett Todd <bet@std.sdi.com>, the
interface by myself. Bennett's original posting to alt.sources can be
found in the subdirectory othello. I modified it quite a bit.
Moves can be made by clicking the left mouse button (or return key)
anywhere in the square you want to put a block in.
The depth to which the computer will search may be set to any number
between 1 and 9. The default is a variable depth, which is 3 for most
of the game. The more intelligent it is (higher numbers), the longer
it takes to make a move. There is an upper limit of (around) 30
seconds for a computer move. At that point, the search is terminated.
Clearly a faster processor will be able to check more positions in the
30 seconds.
While the computer is thinking, the only button which works is the
quit button.
Some ways of playing the game:
$ vga_othello -r # reverse player colours
$ vga_othello -d5 -c # computer starts, search depth of 5

1.3 26 Feb 1995 Added screen redrawing
-----
Mines
-----
This is the game of mines, sharing many similarities with the Windows
game of minesweeper, and xmines.
The availability of this game, along with vga_klondike from
vga_cardgames (available separately), makes Windows obsolete. 8-)
Moves can be made by pressing the left mouse button (or return key)
anywhere in the square you want to expose. If it is a mine, the game
is over.
Pressing the middle mouse button (or both left and right mouse
buttons, for those with two button mice) in a square which is already
exposed will highlight all the squares around it, except those marked
with a flag, if the number of squares around it marked with a flag is
less than the number on the exposed square. If the number of squares
around it marked with a flag is equal to (or greater than) the number
on the exposed square, the squares not marked with a flag will be
cleared.
Pressing the right mouse button (or space key) on a square will cycle
the mark on the square from nothing, to a flag, to ?, to nothing. The
? mark does not protect you if you click on the square with the left
mouse button.
Some ways of playing the game:
$ vga_mines # play on a 20x20 board with 100 mines
$ vga_mines -w 10 -h 10 -d 0.1 # play on a 10x10 board with 10 mines
$ vga_mines -w 8 -h 8 -d 0.16 # minesweeper "Beginner" board
$ vga_mines -w 16 -h 16 -d 0.16 # minesweeper "Intermediate" board
$ vga_mines -w 30 -h 16 -d 0.207 # xmines, minesweeper "Expert" board
