Review Answers
1 A motion tween requires a symbol instance on the Stage and its own layer, which is
called a Tween layer. No other tween or drawing object can exist on the Tween layer.
2 A motion tween creates smooth transitions between different keyframes of an object’s
location, scale, rotation, transparency, brightness, tint, filter values, or 3D rotation
or translation.
3 A keyframe marks a change in one or more of an object’s properties. Keyframes are
specific to each property, so that a motion tween can have keyframes for position that
are different from keyframes for transparency.
4 To edit the path of an object’s motion, choose the Selection tool and click and drag
directly on the path to bend it. You can also choose the Convert Anchor Point tool
and Subselection tool to pull out handles at the anchor points. The handles control the
curvature of the path.
5 Three ways to add easing to a motion tween include the following:
• Select the motion tween on the Timeline and change the Ease value in the
Properties inspector.
• In the Motion Editor, right-click/Ctrl-click on any keyframe to pull out control
handles and change the curvature of the graph.
• Add a preset ease to the Ease category of the Motion Editor and apply it to a property.
