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 progressively
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.
- -display host:display.screen
Specifies which X display we should use.
Draw on the root 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.
- -visual visual
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, directcolor, number
If a decimal or hexadecimal number is used,
is consulted to obtain the required visual.
- -foreground color
Specifies the default foreground color.
- -background color
Specifies the default background color.
- -bgrowth integer
Specifies the growth rate of the bomb explosions.
- -lrate integer
Set the initial rate of laser fire.
Have the computer player skip the learning process.
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.
