Penetrate simulates the arcade classic with the cities and the stuff
shooting down from the sky and stuff. The computer plays against
itself, desperately defending the forces of good against those thingies
raining down. Bonus cities are awarded at ever-increasing intervals.
Every five levels appears a bonus round. The computer player gets pro-
gressively more intelligent as the game progresses. Better aim, more
economical with ammo, and better target selection. Points are in the
bottom right, and high score is in the bottom left. Start with -smart
to have the computer player skip the learning process.
Specifies which X display we should use.
-root Draw on the root window.
-window Draw on a newly-created window. This is the default.
Install a private colormap for the window.
Don't install a private colormap for the window.
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. Possible choices include
default, best, mono, monochrome, gray, grey, color, staticgray,
staticcolor, truecolor, grayscale, greyscale, pseudocolor,
If a decimal or hexadecimal number is used, XGetVisualInfo(3X)
is consulted to obtain the required visual.
Specifies the default foreground color.
Specifies the default background color.
Specifies the growth rate of the bomb explosions.
Set the initial rate of laser fire.
-smart Have the computer player skip the learning process.
-fps Display the current frame rate and CPU load.
The layout of the screen isn't quite the same as the game this program
tries to emulate. In this this program, the missiles come out of the
cities; when really, there are supposed to be three missile bases on
hills, with the cities in the valleys between them.
