17 The maze program creates a "random" maze and then solves it with graph‐
18 ical feedback.
19
21 maze accepts the following options:
22 --window
24 Draw on a newly-created window. This is the default.
25 --root Draw on the root window.
27 --window-id number
29 Draw on the specified window.
30 --install
32 Install a private colormap for the window.
33 --visual visual
35 Specify which visual to use. Legal values are the name of a
36 visual class, or the id number (decimal or hex) of a specific
37 visual.
38 --grid-size pixels
40 The size of each block of the maze, in pixels; default is 0,
41 meaning pick a random grid size. Minimum meaningful value is
42 2.
43 --live-color color
45 The color of the path.
46 --dead-color color
48 The color of the failed path (it is also stippled with a 50%
49 pattern.)
50 --skip-color color
52 The maze solver will choose to not go down a path if it can
53 "see" (in a straight line) that it is a dead end. This is the
54 color to use for paths that are skipped for this reason.
55 --surround-color color
57 If the maze solver ever completely encloses an area within the
58 maze, then it knows that the exit is not in there (and in fact
59 the interior of that area might not even be reachable.) It
60 will mark out those cells using this color.
61 --solve-delay integer
63 Delay (in microseconds) between each step of the solution path.
64 Default 5000, or about 1/200th second.
65 --pre-delay integer
67 Delay (in microseconds) between generating a maze and starting
68 to solve it. Default 2000000 (2 seconds.)
69 --post-delay integer
71 Delay (in microseconds) after solving a maze and before gener‐
72 ating a new one. Default 4000000 (4 seconds.)
73 --generator num
75 Sets the algorithm that will be used to generate the mazes. The
76 default is -1, which randomly selects an algorithm for each
77 maze that is generated. Generator 0 is the original one, and
78 works by walking around randomly until we hit a place we've
79 been before, then backtracking and trying a new direction some‐
80 where. Generator 1 picks a random spot in the maze, then draws
81 a straight wall from that spot in a random direction until it
82 hits another wall (and continues until the maze is complete).
83 Generator 2 is based on sets. Initially all cells are in dif‐
84 ferent sets. Then two neighboring cells are chosen and if they
85 are in different sets, their sets are joined. If they were in
86 the same set, a wall is built between them. This continues un‐
87 til the maze is complete.
88 All generators generate mazes with a certain 'characteristic'.
90 See if you can spot them!
91 The three algorithms are essentially Kruskal, Prim, and a
93 depth-first recursive backtracker.
94 --max-length num
96 Controls the maximum length of walls drawn in one go by genera‐
97 tor 1.
98 Clicking the mouse in the maze window controls it.
100 LeftButton Clears the window and restarts maze.
102 MiddleButton Pause or unpause the program.
104 RightButton Exit.
106 --fps Display the current frame rate and CPU load.
108
110 Expose events force a restart of maze.
111 Mouse actions are based on "raw" values (Button1, Button2 and Button3)
113 instead of using the pointer map.
114
116 DISPLAY to get the default host and display number.
117 XENVIRONMENT
119 to get the name of a resource file that overrides the global
120 resources stored in the RESOURCE_MANAGER property.
121 XSCREENSAVER_WINDOW
123 The window ID to use with --root.
