Q1: When I insert a keyframe, Flash automatically creates a Motion Tween from the previous keyframe to my newly inserted one. Why is this happening?
A1: When you insert a keyframe, Flash copies the previous keyframe (the contents and the frame settings). If the previous keyframe already has been set to tween, the new keyframe will have the same setting.
Q2:Why can't I Motion Tween more than one symbol?
A2: You can have multiple shapes inside the symbol you're tweening. But the rule says only one symbol per layer. You'll see in Hour 11, “Using Layers in Your Animation,” that you need to separate each tweening symbol into its own layer.
Q3:When I use the Rotate setting in my keyframe, my symbol rotates but it's very lopsided. Why?
A3: The symbol rotates around its center point. You should edit the master symbol and position the graphic in the center. Alternatively, you can use the Transform tool to modify the axis of rotation for just one instance. For more about this, review Hour 5.
Q4:Why doesn't my Motion Tween follow a smooth path?
A4: Motion Tween can tween more than just position. When tweening position, Flash moves directly from one keyframe to the next, finding the shortest path between two points. Wouldn't it be cool if you could draw a curve and tell Flash to follow the path you drew? You can. It's called a Motion Guide layer, and we'll cover it in Hour 11.
Q5:My Motion Tween playback is very jumpy—not smooth at all. Why?
A5: First, if the symbol you're tweening has a changing Alpha color effect, consider a different effect, such as Brightness (Alpha causes the computer to work hard and results in slow playback). If Alpha tween isn't your problem, analyze the framerate and the total frames in your Timeline. Revisit Hour 6, “Understanding Animation,” for a review of these concepts. If your tween spans more frames, each step will be smaller and, hence, appear smoother.
