maze — an automated X11 demo repeatedly creating and solving a random maze
Synopsismaze [-display host:display.screen] [-foreground color] [-background color] [-window] [-root] [-install] [-visual visual] [-grid-size pixels] [-live-color color] [-dead-color color] [-solve-delay usecs] [-pre-delay usecs] [-post-delay usecs] [-generator integer] [-max-length integer] [-fps]
DescriptionThe maze program creates a "random" maze and then solves it with graphical feedback.
Optionsmaze accepts the following options:
- Draw on a newly-created window. This is the default.
- Draw on the root window.
- 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 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
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 generator 1.
Clicking the mouse in the maze window controls it.
- Clears the window and restarts maze.
- Pause or unpause the program.
- Display the current frame rate and CPU load.
BugsExpose events force a restart of maze.
Mouse actions are based on "raw" values (Button1, Button2 and Button3) instead of using the pointer map.
- to get the default host and display number.
- to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.
