33 !!OPTIONS

35
36 ''maze'' accepts the following options:
37
38
39 __-window__
40
41
42 Draw on a newly-created window. This is the
43 default.
44
45
46 __-root__
47
48
49 Draw on the root window.
50
51
52 __-install__
53
54
55 Install a private colormap for the window.
56
57
58 __-visual__ ''visual''
59
60
61 Specify which visual to use. Legal values are the name of a
62 visual class, or the id number (decimal or hex) of a
63 specific visual.
64
65
66 __-grid-size__ ''pixels''
67
68
69 The size of each block of the maze, in pixels; default is 0,
70 meaning pick a random grid size.
71
72
73 __-live-color__ ''color''
74
75
76 The color of the path.
77
78
79 __-dead-color__ ''color''
80
81
82 The color of the failed path (it is also stippled with a 50%
83 pattern.)
84
85
86 __-skip-color__ ''color''
87
88
89 The maze solver will choose to not go down a path if it can
90
91
92 __-surround-color__ ''color''
93
94
95 If the maze solver ever completely encloses an area within
96 the maze, then it knows that the exit is not in there (and
97 in fact the interior of that area might not even be
98 reachable.) It will mark out those cells using this
99 color.
100
101
102 __-solve-delay__ ''integer''
103
104
105 Delay (in microseconds) between each step of the solution
106 path. Default 5000, or about 1/200th second.
107
108
109 __-pre-delay__ ''integer''
110
111
112 Delay (in microseconds) between generating a maze and
113 starting to solve it. Default 2000000 (2
114 seconds.)
115
116
117 __-post-delay__ ''integer''
118
119
120 Delay (in microseconds) after solving a maze and before
121 generating a new one. Default 4000000 (4
122 seconds.)
123
124
125 __-generator__ ''num''
126
127
128 Sets the algorithm that will be used to generate the mazes.
129 The default is -1, which randomly selects an algorithm for
130 each maze that is generated. Generator 0 is the original
131 one, and works by walking around randomly until we hit a
132 place we've been before, then backtracking and trying a new
133 direction somewhere. Generator 1 picks a random spot in the
134 maze, then draws a straight wall from that spot in a random
135 direction until it hits another wall (and continues until
136 the maze is complete). Generator 2 is based on sets.
137 Initially all cells are in different sets. Then two
138 neighboring cells are chosen and if they are in different
139 sets, their sets are joined. If they were in the same set, a
140 wall is built between them. This continues until the maze is
141 complete.
142
143
144 All generators generate mazes with a certain
145 'characteristic'. See if you can spot them!
146
147
148 __-max-length__ ''num''
149
150
151 Controls the maximum length of walls drawn in one go by
152 generator 1.
153
154
155 __-bridge__
156
157
158 __-no-bridge__
159
160
161 Controls whether or not a 'bridge' will appear over the
162 logo.
163
164
165 Clicking the mouse in the maze window controls
166 it.
