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:

According to the suggested process of creating a motion tween, what should you always do before inserting keyframes?

  1. Save the file and take a deep breath because Flash might crash.

  2. Ensure that the object in the first keyframe is an instance of a symbol.

  3. Use the Properties panel to tint the instance in the first keyframe.

2:

When you want to edit the position of a symbol instance in a particular keyframe, what must you first ensure?

  1. That the red current-frame marker is in the frame you want to edit

  2. That you concentrate on the frame that you intend to edit and then move the instance

  3. That the symbol isn't red

3:

A motion tween requires two keyframes. When establishing that you want a tween between those two keyframes, exactly where do you make your tween settings?

  1. In the Properties panel, when the symbol instance in Keyframe 1 is selected

  2. In the Properties panel, when the second keyframe is selected

  3. In the Properties panel, when the first keyframe is selected

Quiz Answers

A1:

B. Saving is always a good idea, but it's not really necessary. You want to make sure the first keyframe contains a symbol because it will be copied into the new keyframe and you need symbols in both keyframes for a motion tween.

A2:

A. As surprising as it sounds, people often try option B (also known as the E.S.P. method). This issue falls under a general suggestion I call "know where you are." If you want to edit Frame 1, you need to make sure the red current-frame marker is in Frame 1.

A3:

C. You always establish how Flash is to tween from one keyframe to the next by accessing the Properties panel for the first keyframe.

Exercises

Most of the motion tweens you implemented in this hour tweened only position. Try these exercises that use motion tween on other properties, such as scale and color effect:

  1. Create a bouncing ball that squashes a little bit before bouncing back when it hits the ground. You'll need five keyframes: In addition to the first keyframe with the ball up high, you'll need a keyframe for when the ball reaches the ground and another keyframe for when the ball's in a squashed position. Use onion skinning to line up the bottom of the squashed ball with the bottom of the unsquashed ball. You need a keyframe in the down position but not squashed, and you need a keyframe at the end that corresponds to the initial position. Try using easing where you think it helps.

  2. Make a simple tween in which text tweens from entirely transparent to its normal opaque (non-alpha) state. Consider other ways to achieve this besides using the Alpha effect. Be sure to make a symbol from text before you add keyframes.
