NAME
maze - an automated X11 demo repeatedly creating and solving a random
maze
SYNOPSIS
maze [-display host:display.screen] [-foreground color] [-background
color] [-window] [-root] [-install] [-visual visual] [-grid-size pix-
els] [-live-color color] [-dead-color color] [-solve-delay usecs]
[-pre-delay usecs] [-post-delay usecs] [-generator integer]
[-max-length integer] [-fps]
DESCRIPTION
The maze program creates a "random" maze and then solves it with graph-
ical 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. Minimum meaningful value is
2.
-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 gener-
ating 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 some-
where. 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 dif-
ferent 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 un-
til the maze is complete.
All generators generate mazes with a certain 'characteristic'.
See if you can spot them!
The three algorithms are essentially Kruskal, Prim, and a
depth-first recursive backtracker.
-max-length num
Controls the maximum length of walls drawn in one go by genera-
tor 1.
Clicking the mouse in the maze window controls it.
LeftButton Clears the window and restarts maze.
MiddleButton Pause or unpause the program.
RightButton Exit.
-fps Display the current frame rate and CPU load.
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.
