The pong program simulates an ancient Pong home video game, as well as various artifacts from displaying it on a color TV set.
pong accepts the following options:
Draw on a newly-created window. This is the default.
Draw on the root window.
If on a color display, pretend we're on a monochrome display.
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.
The score of the game will be the current time.
- -noise float
How noisy the video signal should be (between 0.0 and 4.0 or so).
Display the current frame rate and CPU load.
- (-p1 | -p2) mode
Set a player to either ai, mouse, tablet, kbleft (for W and S), or kbright (or just kb, for arrow keys).
to get the default host and display number.
to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.
Notable X resources supported include the following which correspond to standard TV controls: analogTVTint, analogTVColor, analogTVBrightness, and analogTVContrast. They range from 0 to 100, except for tint which is an angle between -180 and +180.
