Workshop

 < Day Day Up > 

The Workshop consists of quiz questions and answers to help you solidify your understanding of the material covered in this hour. You should try to answer the questions before checking the answers.

Quiz

1:

How can you draw into a Mask layer and see the effect of the mask on the Masked layer at the same time?

  1. You can't.

  2. You need to use red fill.

  3. You need to lock both layers.

2:

How many layers can be masked by setting one layer to Mask?

  1. One. Each Masked layer must have its own Mask layer.

  2. As many as you want.

  3. None. It's the other way around; one Masked layer can have lots of Mask layers below it.

3:

What is the one situation in which being efficient (such as using the Library) is not especially important?

  1. Nowhere in Flash. You should always be efficient.

  2. In Guide layers because they don't export with the movie.

  3. In layers you hid because they're hidden.

Quiz Answers

A1:

A. I love trick questions. In fact, you can lock both layers and see the effect, but you can't draw into a locked layer (while it's locked anyway). Don't worry if I tricked you; this quiz is just supposed to teach.

A2:

B. One Mask layer can shadow as many Masked layers as you want. It actually appears to happen outside your control sometimes when you're adding layers. Masked layers have a special icon, and the layer name is indented.

A3:

B. I suppose you should always be efficient, but Guide layers aren't exported with the movie, so they won't hurt the user in any way. Also remember that hiding a layer only hides it while you're authoring (just use Test Movie to see this).

Exercises

  1. Create a Mask layer that contains filled window shapes, and in the Masked layer place a large image (imported or created in Flash) of the sky and some clouds. Motion tween the image to create the effect that the sky is passing by (in the windows). Remember that each window will likely need to be a plain shape (not a symbol), because they're in a Mask layer.

  2. Make a motion guide in the shape of a circle. Suppose you want an object to follow a circle during its motion tween. An enclosed circle for a Motion Guide layer won't work. However, in the Guide layer, you can create an outline of a circle and then cut out a very small segment. Snap the object in the Guided layer to the start of the circle, and in another keyframe, snap the object to the other end of the circle. Try this. Depending on the total number of frames, you might find that the segment you delete can be bigger than you'd think.
