chapter
we
will explain how to access this color memory directly, but you
can make the VIC take care
of
it for you.
On
the front
ofthe
numeric keys 1
through 8 are printed abbreviations for each
of
the eight character colors.

To
change the color
of
the characters, press
and
hold the
CTRL
key,
then press the key for the color you desire. All characters generated at the
keyboard
or
by a program will appear in the color selected. Only characters
displayed after you set the new color will be affected; those already
on
the
screen will not be changed.
Players
and Playllelds
Many graphics programs, especially games
and
simulations, move one
or
more objects against a fixed background.
To
avoid confusion with other
terms,
we
will refer to the objects as players
and
the background as the
playfield.
Not all players will move, and the playfield may change.
In
fact, in some
applications the players will stay in one place and the background will move,
just as in the old movies where the stagecoach sat still while the painted
scenery rolled by behind it.
GRAPHICS
WITH
THE
EXTENDED
CHARACTER
SET
Simple players can be made using the VIC's built-in graphics charac-
ters. These are the shapes and symbols printed on the front
ofthe
keys.
