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 Draw on a newly-created window. This is the default.
24 -root Draw on the root window.
26 -install
28 Install a private colormap for the window.
29 -visual visual
31 Specify which visual to use. Legal values are the name of a
32 visual class, or the id number (decimal or hex) of a specific
33 visual.
34 -grid-size pixels
36 The size of each block of the maze, in pixels; default is 0,
37 meaning pick a random grid size.
38 -live-color color
40 The color of the path.
41 -dead-color color
43 The color of the failed path (it is also stippled with a 50%
44 pattern.)
45 -skip-color color
47 The maze solver will choose to not go down a path if it can
48 "see" (in a straight line) that it is a dead end. This is the
49 color to use for paths that are skipped for this reason.
50 -surround-color color
52 If the maze solver ever completely encloses an area within the
53 maze, then it knows that the exit is not in there (and in fact
54 the interior of that area might not even be reachable.) It
55 will mark out those cells using this color.
56 -solve-delay integer
58 Delay (in microseconds) between each step of the solution path.
59 Default 5000, or about 1/200th second.
60 -pre-delay integer
62 Delay (in microseconds) between generating a maze and starting
63 to solve it. Default 2000000 (2 seconds.)
64 -post-delay integer
66 Delay (in microseconds) after solving a maze and before gener‐
67 ating a new one. Default 4000000 (4 seconds.)
68 -generator num
70 Sets the algorithm that will be used to generate the mazes. The
71 default is -1, which randomly selects an algorithm for each
72 maze that is generated. Generator 0 is the original one, and
73 works by walking around randomly until we hit a place we've
74 been before, then backtracking and trying a new direction some‐
75 where. Generator 1 picks a random spot in the maze, then draws
76 a straight wall from that spot in a random direction until it
77 hits another wall (and continues until the maze is complete).
78 Generator 2 is based on sets. Initially all cells are in dif‐
79 ferent sets. Then two neighboring cells are chosen and if they
80 are in different sets, their sets are joined. If they were in
81 the same set, a wall is built between them. This continues
82 until the maze is complete.
83 All generators generate mazes with a certain 'characteristic'.
85 See if you can spot them!
86 -max-length num
88 Controls the maximum length of walls drawn in one go by genera‐
89 tor 1.
90 -bridge
92 -no-bridge
94 Controls whether or not a 'bridge' will appear over the logo.
95 Clicking the mouse in the maze window controls it.
97 LeftButton Clears the window and restarts maze.
99 MiddleButton Pause or unpause the program.
101 RightButton Exit.
103
105 Expose events force a restart of maze.
106 Mouse actions are based on "raw" values (Button1, Button2 and Button3)
108 instead of using the pointer map.
109
111 DISPLAY to get the default host and display number.
112 XENVIRONMENT
114 to get the name of a resource file that overrides the global
115 resources stored in the RESOURCE_MANAGER property.
