Properties palette. Each keyframe you create can have a tween applied to it. Click on
the Tween drop-down menu and select Motion (Figure 3.9). In the Timeline you will see
the frames in between both keyframes turn blue with a line pointing to the last key-
frame (Figure 3.10). This indicates that a motion tween has been applied.

Step 6: Save and test your movie
Save your file as 3_2_MotionTween.fla . Choose Control > Test Movie to see the fin-
ished results. This exercise demonstrates two animation methods in Flash. The walk
cycle is a frame-by-frame animation made up of 15 unique images, one frame after
another. The movement across the Stage is a tweened animation. Flash created all the
transitional frames required between a starting keyframe and an ending keyframe. Now
that you can animate in Flash, let's simulate some depth using the tweening method.
Exercise 3.2: Parallax Scrolling Using Bitmap Images
How do artists achieve depth in their paintings? They paint objects in the foreground,
middle ground, and background. Think of each ground as a separate layer in Flash. To
achieve parallax scrolling, each layer must move at a different speed. Let's experiment.
