Description

The pong program simulates an ancient Pong home video game, as well as various artifacts from displaying it on a color TV set.

Options

pong accepts the following options:

-window

Draw on a newly-created window.  This is the default.

-root

Draw on the root window.

-mono

If on a color display, pretend we're on a monochrome display.

-install

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.

-clock

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).

-fps

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).

Environment

DISPLAY

to get the default host and display number.

XENVIRONMENT

to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.

X Resources

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.
