The maze program creates a "random" maze and then solves it with
graphical feedback.
OPTIONS
maze
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 seconds.)
-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 generated. 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
random 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 complete). Generator 2 is based on sets. Initially all cells
are in different sets. Then two neighboring cells are chosen and if
they are in different 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_MANAGER property.
