Similar to Adobe
Illustrator and Adobe Flash, symbols can be divided
in
different
layers. Not only divided by layers, symbols can also be divided
into frames.
By
dividing
symbols
in
layers and
frames, there are
some advantages we
can obtain.
First
one
is
that
we can
easily
edit
and
replace
the
specific
symbols
because
of
the
tidiness.
The other one is that we can reduce the
memory usage of the computer when running
the
flash program. Unseen symbols
in specific
frames can be removed from the scene so the
computer will not need to calculate and draw it.
Figure 4: Adobe Flash Time Line
Objects are
drawn
on
the
stage
by
using
drawing tools.
There
are
various
combinations we
can
do
with
the
drawing
tools
to
creatively
create
an
object.
For
example, by
combining Circle shape
tool with Square shape tool,
we
can create objects
like
car,
table,
etc.
After
objects
are
drawn and
completed,
it
must
be
turned
into
symbols
for
the
animation
and
programming process.
These
symbols are
automatically
stored into the application’s library.
Symbols are
divided
into
three
types.
Graphic
symbols, Button
symbols
and
Movie Clip symbols. Each of the symbols
has its own timelines and stage. Similar to the
main timeline, we can add the frames, keyframes and layers to the symbol’s timeline.
