Tween motion along a path
Motion guide layers let you draw paths along which tweened instances, groups, or text blocks can be animated. You
can link multiple layers to a motion guide layer to have multiple objects follow the same path. A normal layer that is
linked to a motion guide layer becomes a guided layer.
In this example, two objects on separate layers are attached to the same motion path.

Create a motion path for a tweened animation
1
Create a motion-tweened animation sequence. If you select Orient To Path, the baseline of the tweened element
orients to the motion path. If you select Snap, the registration point of the tweened element snaps to the motion path.
2
Do one of the following:
•
Select the layer containing the animation, and select Insert > Timeline > Motion Guide.
•
Right-click (Windows) or Control-click (Macintosh) the layer containing the animation and select Add Motion
Guide.
Flash creates a new layer above the selected layer with a motion guide icon to the left of the layer name.
Motion guide layer above selected layer
3
Use the Pen, Pencil, Line, Circle, Rectangle, or Brush tool to draw the desired path.
4
Snap the center to the beginning of the line in the first frame, and to the end of the line in the last frame.
Note: For best snapping results, drag the symbol by its registration point.
5
To hide the motion guide layer and the line so that only the object’s movement is visible while you work, click in
the Eye column on the motion guide layer.
