32
33
34 Speedmine!
35
36
37 Down the speedmine, you'll find speed
38
39
40 to satisfy your moving needs;
41
42
43 So if you're looking for a blast
44
45
46 then hit the speedmine, really fast.
47
48
49 Speedworm loves you.
50
51
52 Speedworm likes to bump and grind
53
54
55 and chase her tail, and dance around
56
57
58 she really is a funky friend;
59
60
61 she's made of speed from end to end.
62
63
64 You can configure stuff either with command-line options or
65 X resources.
66 !!OPTIONS
67
68
69 __-display__ ''host:display.screen''
70
71
72 Specifies which X display we should use (see the section
4 perry 73 DISPLAY NAMES in X(1) for more information about this
1 perry 74 option).
75
76
77 __-root__
78
79
80 Draw on the root window.
81
82
83 __-window__
84
85
86 Draw on a newly-created window. This is the
87 default.
88
89
90 __-install__
91
92
93 Install a private colormap for the window.
94
95
96 __-noinstall__
97
98
99 Don't install a private colormap for the
100 window.
101
102
103 __-visual__ ''visual''
104
105
106 Specify which visual to use. Legal values are the name of a
107 visual class, or the id number (decimal or hex) of a
108 specific visual. Possible choices include
109
110
111 default, best, mono, monochrome, gray, grey, color,
112 staticgray, staticcolor, truecolor, grayscale, greyscale,
113 pseudocolor, directcolor, ''number''
114
115
116 If a decimal or hexadecimal number is used,
117 __XGetVisualInfo__(3X) is consulted to obtain the
118 required visual.
119
120
121 __-worm__
122
123
124 Be a happy spastic worm instead of a tunnel.
125
126
127 __-wire__
128
129
130 Specifies that the tunnel/worm should always be rendered in
131 wireframe style.
132
133
134 __-nowire__
135
136
137 Specifies that the tunnel/worm should be rendered normally.
138 Note that tunnel rendering may still temporarily switch to
139 wireframe style when a wireframe bonus is hit, if
140 __bonuses__ are enabled.
141
142
143 __-foreground__ ''color''
144
145
146 Specifies the default foreground color.
147
148
149 __-background__ ''color''
150
151
152 Specifies the default background color.
153
154
155 __-darkground__ ''color''
156
157
158 Specifies the color of the darkest portions of the ground
159 (or the worm's belly.) The ground/belly is colored by a
160 gradient between __darkground__ and
161 __lightground.__
162
163
164 __-lightground__ ''color''
165
166
167 Specifies the color of the lightest portions of the
168 ground/belly. The ground/belly is colored by a gradient
169 between __darkground__ and
170 __lightground.__
171
172
173 __-tunnelend__ ''color''
174
175
176 Specifies the color of the light at the end of the
177 tunnel.
178
179
180 __-delay__ ''microseconds''
181
182
183 Specifies the delay between drawing successive frames. If
184 you do not specify __-sync__, some X servers may batch up
185 several drawing operations together, producing a less smooth
186 effect. This is more likely to happen in monochrome mode (on
187 monochrome servers or when __-mono__ is
188 specified).
189
190
191 __-maxspeed__ ''number''
192
193
194 Specifies an upper bound on the speed of normal movement.
195 This does not affect the speed that may be attained when
196 hitting a speed bonus.
197
198
199 __-thrust__ ''number''
200
201
202 Specifies the thrust constantly applied. Positive numbers
203 indicate a forwards thrust, negative numbers indicate a
204 backwards thrust.
205
206
207 __-gravity__ ''number''
208
209
210 Specifies the effect of gravity. Larger numbers will
211 increase acceleration downhill and decrease acceleration
212 uphill.
213
214
215 __-vertigo__ ''number''
216
217
218 Specifies to what level the demo should accentuate the
219 curvature and windiness of the tunnel or worm.
220
221
222 __-terrain__
223
224
225 Continuously generate a fractal terrain to simulate the
226 rockiness of the tunnel walls, or the texture of the worm's
227 skin.
228
229
230 __-noterrain__
231
232
233 Do not generate terrain. When this option is set, all
234 surfaces are flat.
235
236
237 __-smoothness__ ''number''
238
239
240 When __-terrain__ is set, specifies how smooth the walls
241 or skin are.
242
243
244 __-curviness__ ''number''
245
246
247 Controls how much the generated tunnel (or worm) should
248 curve left and right, and dip up and down.
249
250
251 __-twistiness__ ''number''
252
253
254 Controls how much the generated tunnel (or worm) twists
255 around itself.
256
257
258 __-widening__
259
260
261 Specifies that the generated tunnel (or worm) may vary in
262 width.
263
264
265 __-nowidening__
266
267
268 Specifies that the average width should be kept
269 constant.
270
271
272 __-bumps__
273
274
275 Indicates that the simulation should take the bumpiness of
276 the ground into account and allow the animation to shake and
277 rattle when travelling over rough ground. Or that the worm
278 should be allowed to bump around and shake her
279 booty.
280
281
282 __-nobumps__
283
284
285 Indicates that the bumpiness of the ground should be
286 ignored, such that the simulation will glide through the
287 tunnel. Or that the worm should calm down and behave
288 herself.
289
290
291 __-bonuses__
292
293
294 Indicates that the demo should include bonus events. These
295 include speed bonuses, spins, and changes of viewpoint and
296 rendering style.
297
298
299 __-nobonuses__
300
301
302 Indicates that bonuses should not be included in the
303 demo.
304
305
306 __-crosshair__
307
308
309 Specifies that a gaming style crosshair be drawn on the
310 simulation. This serves little purpose but may make hardcore
311 gamers feel more comfortable.
312
313
314 __-nocrosshair__
315
316
317 Specifies that no crosshair be drawn.
318
319
320 __-psychedelic__
321
322
323 Specifies that a psychedelic colormap should be generated.
324 When this is set, the walls and ground of the tunnel are
325 drawn in an often changing rainbow of colours.
326
327
328 __-nopsychedelic__
329
330
331 Specifies that a normal colormap should be used, with muted
332 walls and a grey road.
