X-BASED DINOSAUR CUBE
===================== Dino X widgets, V5.3
It has been tested on the following platforms:
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
/usr/lib/X11/etc/xmodmap.std . If not defined
** 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
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
xdino [motif version will be xmdino]
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
xdino
or if you have Motif, uncomment appropriate sections, then try:
make -f Makefile.std all.xm
xmdino
You should have Dino.ad copied to $(HOME)/Dino or
/usr/lib/X11/app-defaults/Dino to run, especially if the background
is similar to one of the faces. Edit this file for your preferences.
You might want to move xdino into /usr/bin/X11 (or wherever your
X binaries are).
You might also want to move xdino.man to /usr/man/man6/xdino.6
ANYTHING SPECIAL IN USING?
Click on the left mouse button to move a piece. Release it on an
adjacent piece on the same face. 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.
'O' or 'o' to toggle orient mode.
'2' (not the keypad 2) to set period 2 mode.
'3' (not the keypad 3) to set period 3 mode.
'B' or 'b' to set both period 2 and period 3 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 2d dino as:
7 8 9
^
3 < > 6
v
1 2 3
The key pad along with the use of the mouse will allow you to move
the cube i.e.,
KP_7=>TopLeft KP_8=>Top KP_9=>TopRight
KP_3=>Left KP_6=>Right
KP_1=>BottomLeft KP_2=>Bottom KP_3=>BottomRight
Note: Top, Left, Right, and Bottom only work when the control key
is pressed and there is no analog for 3d dino.
Key pad for 3d dino, use your intuition (is this a cop out or what?).
The key pad is defined differently depending on which side of the cube
your mouse is pointing at.
The alt keys will allow one to move the center of the cube. The
2 opposite corners do not move.
The shift keys will allow one to access "Period 2" turns from "Both"
mode, otherwise it assumes "Period 3" turning. Edges turn in
"Period 2" and corners turn in "Period 3". The "Period 2" mode has
extra cuts around the faces.
The control key allows you to move the whole cube at once without
being entered as a move. Hold down the control key while using the
left mouse button or the keypad.
Try resizing the cube. Notice the puzzle resizes to take advantage
of the "room" available.
The title is in the following format (non-motif version):
xdino{2|3}d.{2|3|both}: (<Number of moves>/\
{<Record number of moves>|NEVER|PRACTICE}) - <Comment>
{2|3}: current dimensional view
{2|3|both}: current turning mode or both modes.
{<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. If you know of one
let me know.
Also a tesseract (4D cube) would be nice. (Does such an analog exist
for 4d?)
Personally, I have solved "Period 3" mode using this program.
The "Period 2" mode was suggested by Derek Bosch <bosch@sgi.com>.
The physical puzzle ("Period 3") is now available. It is called
a Triangle - 4 Cube - Dinosaur with colored dinosaurs on it, (or
Triangle - 4 Cube - 6 Colors with solid colors, (a 4 color and a
2 color are also available with point oriented coloring)).
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. The format will probably change to become more readable.
Consider the 2d cross representation:
practice: 0 false, 1 true
moves: 0-MAXINT
startingPosition:
0 R where the starting unrandomized faces would be,
1 2 3 Y W G each face has 4 corners
4 O if orient mode, orientation number follows face number
5 B 0 up, 1 right, 2 down, and 3 left.
This is then followed by the moves
move #: face corner direction control
each turn is with respect to a corner on a face. The corners
start at the upper right and work clockwise.
Direction is represented as 0 upper right, 1 lower right, 2 lower
left, 3 upper left, 5 clockwise, 7 counterclockwise, 8 up, 9 right,
10 down, and 11 left.
Style is represented as 0, 1, or 2, 0 if just a corner is rotated, 1
1 if the center of the cube is moved, and 2 if a period 2 twist.
Control is represented as 0 or 1, 1 if the whole cube is moved at once
(here i and j do not matter), 0 if not. The xdino 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.
