# xtriangles(6x)

Triangles X widget

## NAME

xtriangles - Triangles X widget

## SYNOPSIS

**/usr/games/xtriangles** \[-geometry \[{width}\]\[x{height}\]\[{+-}{xoff}\[{+-}{yoff}\]\]\] \[-display \[{host}\]:\[{vs}\]\] \[-{foreground\|fg} \<color\>\] \[-{background\|bg} \<color\>\] \[-{border\|bd} \<color\>\] \[-tile \<color\>\] \[-{size \<int\>\] \[-username {string}\]

## DESCRIPTION

This is basically no harder than the 15 puzzle.   The 15 puzzle was originally made around 1879 (the 14-15 puzzle of Sam Loyd was made soon after).   T. R. Dawson in Original Puzzles has a similar puzzle with 4 diamond- and 6 triangular-shaped pieces.

## FEATURES

Click "**mouse-left**" button to move a tile.  Clicks on spaces or clicks tiles that are not in line with the two spaces will not move the tiles.  Notice one can move more than one tile at a time by clicking on the tile farthest from the spaces but in line with the spaces.

Click "**mouse-right**" button, or press "**R**" or "**r**" keys, to randomize the puzzle.  One must double click on "**mouse-right**" if the puzzle is being worked on.

Press "**I**" or "**i**" keys to increase the number of tiles.

Press "**D**" or "**d**" keys to decrease the number of tiles.

"**S**" or "**s**" keys reserved for the auto-solver (unimplemented).

Press "**U**" or "**u**" keys to undo move.

Press "**G**" or "**g**" keys to get a saved puzzle.

Press "**W**" or "**w**" keys to write or save a puzzle.

Press "**Q**", "**q**", or "**CTRL-C**" keys to kill program.

Use the key pad, "R" keys, or arrow keys to move without the mouse.\
 Key pad is defined for Triangles as:\
 7   9  Upper Left, Upper Right\
\
   ^ \
 4\< \>6  Left, Right\
\
   v\
 1   3  Bottom Left, Bottom Right

The title is in the following format (non-motif version):

xtriangles: \<size\> @ (\<Number of moves\>/{\<Record number of moves\> \<username\>\|"NEVER noaccess"}) - \<Comment\>

If there is no record of the current puzzle, it displays "NEVER noaccess".

## OPTIONS

- **-geometry {+\|-}*X*{+\|-}*Y***

  This option sets the initial position of the triangles window (resource name "*geometry*").

- **-display *host*:*dpy***

  This option specifies the X server to contact.

- **-{foreground\|fg} *color***

  This option specifies the foreground of the triangles window (resource name "*foreground*").

- **-{background\|bg} *color***

  This option specifies the background of the triangles window (resource name "*background*").

- **-{border\|bd} *color***

  This option specifies the border color of the tiles in the triangles window (resource name "*borderColor*").

- **-tile *color***

  This option specifies the tile color of the triangles window (resource name "*tileColor*").

- **-size \<*int*\>**

  This option allows you to change the number of triangles in a row (resource name "*sizeA*").

- **-username *string***

  This option specifies the user name for any records made or else it will get your login name (resource name "*userName*").

## SAVE FORMAT

The format is not standard.  The reason for this is that this is simple and I do not know what the standard is.

size: 1-16 \<number of tiles in a row of the same orientation as the puzzle\>\
 moves: 0-MAXINT \<total number of moves\>

startingPosition: \<array of tile positions where 0 is the empty space for the UP triangle and -1 is the empty space for the DOWN triangle\>

This is then followed by the moves, starting from 1.

move #: \<direction\>

Direction is represented as 0 upper right, 1 right, 2 lower right, 3 lower left, 4 left, and 5 upper left.

Caution: the program may crash on corrupted input.
