DESCRIPTION
The maze program creates a "random" maze and then solves
it with graphical feedback.
OPTIONSmaze accepts the following options:
-window Draw on a newly-created window. This is the
default.
-root Draw on the root window.
-install
Install a private colormap for the window.
-visual visual
Specify which visual to use. Legal values are the
name of a visual class, or the id number (decimal
or hex) of a specific visual.
-grid-size pixels
The size of each block of the maze, in pixels;
default is 0, meaning pick a random grid size.
-live-color color
The color of the path.
-dead-color color
The color of the failed path (it is also stippled
with a 50% pattern.)
-skip-color color
The maze solver will choose to not go down a path
if it can "see" (in a straight line) that it is a
dead end. This is the color to use for paths that
are skipped for this reason.
-surround-color color
If the maze solver ever completely encloses an
area within the maze, then it knows that the exit
is not in there (and in fact the interior of that
area might not even be reachable.) It will mark
out those cells using this color.
-solve-delay integer
Delay (in microseconds) between each step of the
solution path. Default 5000, or about 1/200th
second.
-pre-delay integer
Delay (in microseconds) between generating a maze
and starting to solve it. Default 2000000 (2 sec
onds.)
-post-delay integer
Delay (in microseconds) after solving a maze and
before generating a new one. Default 4000000 (4
seconds.)
-generator num
Sets the algorithm that will be used to generate
the mazes. The default is -1, which randomly
selects an algorithm for each maze that is gener
ated. Generator 0 is the original one, and works
by walking around randomly until we hit a place
we've been before, then backtracking and trying a
new direction somewhere. Generator 1 picks a ran
dom spot in the maze, then draws a straight wall
from that spot in a random direction until it hits
another wall (and continues until the maze is com
plete). Generator 2 is based on sets. Initially
all cells are in different sets. Then two neigh
boring cells are chosen and if they are in differ
ent sets, their sets are joined. If they were in
the same set, a wall is built between them. This
continues until the maze is complete.
All generators generate mazes with a certain
'characteristic'. See if you can spot them!
-max-length num
Controls the maximum length of walls drawn in one
go by generator 1.
-bridge
-no-bridge
Controls whether or not a 'bridge' will appear
over the logo.
Clicking the mouse in the maze window controls it.
LeftButton Clears the window and restarts maze.
MiddleButton Pause or unpause the program.
RightButton Exit.
BUGS
Expose events force a restart of maze.
Mouse actions are based on "raw" values (Button1, Button2
and Button3) instead of using the pointer map.
ENVIRONMENT
DISPLAY to get the default host and display number.
XENVIRONMENT
to get the name of a resource file that overrides
the global resources stored in the RESOURCE_MAN
AGER property.
