Layers are simple transparent sheets that are placed one on
top of each other. These layers can be moved around, added and
they can also be deleted. They organize your movie and all you
to affect objects without affecting the rest of your movie.
When editing object on a layer, the layer selected will be
the only layer that is being modified. To activate another
layer, you must click on it to select it. While it is
selected, the layer will be highlighted until you deselect it.
To let you know if a layer is active, you will notice a small
pencil beside the layer name.

(Figure 2.5)
The image above is what layers look like. You
see here that there are three layers, and layer "one" is
selected.
Creating and modifying layers:
Create two more layers by clicking the
new layer
button. A new layer is created. Now do it one more time to
have a total of three layers. Perfect, now you must rename
your layers. To do this, you must click on your layer, and
then double click it, you can now change that names of the
layers. In layer 1, rename it to Square, then in layer 2,
rename it to Triangle, and finally rename layer 3 to circle.
Once this is done, you should have the layers looking like
Figure 2.6 below.

(Figure 2.6)
Now, in the Square layer, draw a small square
image located at the far left of your stage. Now select the
Triangle layer, and draw a triangle in the middle of your
stage, but make sure that you fill in the triangle, and you
can use the
line
tool to create, and finally select the Circle layer, and draw
a circle at the far right end of your stage. Once this is
done, you have three different shapes that go with three
different layers.
You can set the order of your layers, to
minimize the appearance of some objects, or just to be more
organized. To set the order, you simply click and drag the
layer up or down to the position you want.

(Figure 2.7)
Set the order of your layers to Circle,
Triangle and then Square. You now see how easy it is to
create, rename and move layers.
Locking and Hiding layers:
Locking layers is useful at times to protect other work while
you are drawing more graphics. To lock or unlock a layer, you
simple click on the
pad lock button and it will display a locked layer. To hide a
layer, you simple click on the
hide button, and
all the content from the layer you just hid will be invisible
until you unhide the layer.
