X-BASED OCTAHEDRON
================== Octahedron X widget, V5.3
It has been tested on the following platforms:
HP 3xx & 700 HP-UX 9.0x X11R5
Sun4, SPARC SunOS 4.1.3 X11R4
Sun4, SPARC SunOS 5.4 X11R5
PC, 486 Linux 1.0.9 X11R5(*)
PC, 486 Linux 1.2.8 X11R6(**)
* Keypad 5 key may not work, in which case, try it with the
Num-Lock on
** Keypad may not work, since various keycodes may not be defined
by default. Check that "KP_1 - KP_9, Home, Up, Prior, Left,
Begin, Right, End, Down, Next" are defined towards the end of
/usr/lib/X11/etc/xmodmap.std . If not defined
cp /usr/lib/X11/etc/xmodmap.std /usr/lib/X11/xinit/.Xmodmap
and then motify this or create your own at ${HOME}/.Xmodmap .
You should just have to uncomment them (get rid of some '!').
This should be done before X is started.
If yours is not in this list, please let me know -- thanks. The
most updated source could be found on ftp.x.org under
/contrib/games/puzzles.
HOW TO BUILD?
Do you have Motif? If so, uncomment line 28 of Imakefile.
It should be easy. Edit the Imakefile (or Makefile.std, see below)
for appropriate settings of variable SCOREFILE then do:
xmkmf
make
xoct [motif version will be xmoct]
Note: if you don't have 'xmkmf' or the "Makefile" it generates
doesn't work well, edit Makefile.std for appropriate settings for
XINCLUDEPATH and XLIBPATH, then try:
make -f Makefile.std
or if you have Motif, uncomment appropriate sections, then try:
make -f Makefile.std all.xm
xmmlink
You should have Oct.ad copied to $(HOME)/Oct or
/usr/lib/X11/app-defaults/Oct to run, especially if the background
is similar to one of the faces. Edit this file for your preferences.
You might want to move xoct into /usr/bin/X11 (or wherever your
X binaries are).
You might also want to move xoct.man to /usr/man/man6/xoct.6
ANYTHING SPECIAL IN USING?
Click on the left mouse button to move a piece. Release it on a
piece in the same row and on the face (but not an adjacent piece
or the move is ambiguous). The puzzle will then turn towards where
the mouse button was released.
Click on the middle mouse button toggle the practice mode. (This is
good for learning moves). Also 'P' or 'p' does the same thing.
One must double click on the middle mouse button if the puzzle is
being worked on.
Click on the right mouse button if you want to randomize the puzzle.
Also 'R' or 'r' does the same thing. One must double click on
the right mouse button if the puzzle is being worked on.
'I' or 'i' to increase or move up the number of "octas".
'D' or 'd' to decrease or move down the number of "octas".
'O' or 'o' to toggle orient mode.
'3' (not the keypad 3) to set period 3 mode.
'4' (not the keypad 4) to set period 4 mode.
'B' or 'b' to set both period 3 and period 4 mode.
'Y' or 'y' to toggle the sticky mode. Increase and decrease capability
is turned off until out of sticky mode.
'S' or 's' to auto-solve. Unfortunately, its unimplemented.
'U' or 'u' to undo last move.
'G' or 'g' to get a saved puzzle.
'W' or 'w' to write or save a puzzle.
'Q', 'q', or Control-C to kill program.
Key pad is defined for octahedron as:
/
7 8 9
^
4 < 5 > 6
v
1 2 3
The key pad along with the use of the mouse will allow you to move the
"octas" i.e.,
KP_DIVIDE=>CCW
KP_7=>TopLeft KP_8=>Top KP_9=>TopRight
KP=>Left KP_5=>CW KP_6=>Right
KP_1=>BottomLeft KP_2=>Bottom KP_3=>BottomRight
The shift keys will allow one to access "Period 4" turns from "Both"
mode, otherwise it assumes "Period 3" turning. Points turn in
"Period 4" and faces turn in "Period 3".
"Sticky" and "Period 3" turning allows only the faces to turn,
It is as if the middle cut of the three cuts did not exist.
"Sticky" and "Period 3" turning allows only the points to turn, it is
as if the middle cut of the three cuts did not exist.
Beware, the "Sticky" mode is a hack and much could be done to improve
its look.
The control key allows you to move the whole octahedron at once
without being entered as a move. Hold down the control key while
using the left mouse button or the keypad. Use with shift change
turning mode.
One has to orient the faces in orient mode, besides getting all the
faces to be the same color. To do this one has to get the lines to
be oriented in the same direction, this only matters with center
"octas", if at all (i.e. those "octas" not on a corner or edge).
Try resizing the octahedron. Notice the puzzle resizes to take
advantage of the "room" available.
The title is in the following format (non-motif version):
xoct.{3|4|both}: {1|2|3|4|5|6|sticky} @ (<Number of moves>/\
{<Record number of moves>|NEVER|PRACTICE}) - <Comment>
{3|4|both}: current turning mode or both modes.
{1|2|3|4|5|6|sticky}: number of "octas" per edge or in sticky mode.
{<Record...}: puzzle is either in practice mode or record mode
In record mode, if there is no record of the current puzzle, it
displays "NEVER".
If you were looking for a auto-solver, sorry. One of the problems in
auto-solvers the generally don't work for different number of cuts.
If you know of one let me know.
Personally, I have solved 1-2 in "Period 3" mode, 1-3 in the
"Period 4" mode, 1 in the "Both" mode, and "Sticky" I have not
solved it in any mode.
Refer to the man page for detailed command line options.
If you want further information on puzzles, I'll be glad :-) to send
it to you.
SAVE FORMAT
The format is not standard. The reason is that this is simple to
produce and the standard notation is no good for variable number of
"octas". The format will probably change to become more readable.
size: 1-6 number of triangles in the same orientation as the
face per row
mode: 3-5; period 3 turning, period 4 turning, and both (5)
orient: 0 false, 1 true lines on "octa" to be oriented
sticky: 0 false, 1 true some "octas" move together
practice: 0 false, 1 true
moves: 0-MAXINT
startingPosition:
0 R where the starting unrandomized faces would be,
3 1 M B each face has size * size "octas"
2 W if orient mode, orientation number follows face number
4 O clockwise numbered like a clock except 0 is up.
7 5 Y P
6 G
This is then followed by the moves
move #: face position direction control
each turn is with respect to a face and position.
Position is 0 to size * size - 1. Position 0 is the center most
triangle, increasing counterclockwise.
Direction is represented as 0 up, 1 upper right, 2 right,
3 lower right, 4 down, 5 lower left, 6 left, 7 upper left,
9 clockwise, and 15 counterclockwise.
Control is represented as 0 or 1, 1 if the whole octahedron is moved
at once (here i and j do not matter), 0 if not. The xoct record
keeper does not count a control move as a move, but here we do.
Caution: the program may crash on corrupted input.
FOUND A BUG?
Send bugs reports and fixes to the author. For bugs, please include
as much information as to their location as possible, since I may not
have the resources to duplicate the them.

HISTORY
[Apr 08, 96] V5.3: Minor changes.
[Jan 31, 96] V5.2: Puzzle can now moved by a more intuitive drag and
drop approach. Pieces will invert, when selected.
Now using dynamic allocation, so there is no maximum size.
[Dec 15, 95] V5.1: Minor updates, RNG for 32/64 bit, border color
to make faces look more realistic.
[Oct 04, 95] V5.0: Xt/Motif, your choice.
[Jun 06, 95] V4.10.1: Warning error fixed.
[May 16, 95] V4.10: Warnings removed from Sun's cc and lint and now
include a random number generator. More freedom in
movement using control+shift.
[Mar 13, 95] V4.4: Removed lint warnings and added a VMS make.com .
[Oct 11, 94] V4.3: Conservative guess for random number generator.
[Oct 07, 94] V4.2: Now allows undos, saves, and recalls.
[Jun 28, 94] V4.1: Can accommodate a auto-solver.
[Jun 05, 94] V4.0: Xt version.
I got some good ideas from oclock.
[Apr 01, 93] V3.0: Motif version.
I got some good ideas from Douglas A. Young's
book: "The X Window System Programming and Applications
with Xt OSF/Motif Edition", particularly his dial widget.
I got some good ideas on presentation from Q. Zhao's
tetris.
[Feb 01, 92] V2.0: XView version.
[Jun 10, 91] V1.0: SunView version.
