sprite data
A sprite generated
in
automatic mode can be moved by specifying a different position in
the
data
structure.
For
each display field,
the
data
is reread and
the
sprite redrawn.
Therefore, if you change the position
data
before the sprite is redrawn,
it
will appear in
a new position and will seem
to
be moving.
