To create a motion tween using the Motion Tweening option:
Click a layer name to make it the active layer, and select an empty keyframe in the layer where
1.
you want the animation to start.
To create the first frame of the motion tween, do one of the following:
2.
Create a graphic object with the Pen, Oval, Rectangle, Pencil, or Brush tool, then convert it
to a symbol. For more information on converting objects to symbols, see
symbols" on page
Create an instance, group, or text block on the Stage.
Drag an instance of a symbol from the Library panel.
Create a second keyframe where you want the animation to end, then select the ending frame
3.
(immediately to the left of the second keyframe on the Timeline).
Do any of the following to modify the instance, group, or text block in the ending frame:
4.
Move the item to a new position.
Modify the item's size, rotation, or skew.
Modify the item's color (instance or text block only).
To tween the color of elements other than instances or text blocks, use shape tweening. See
"Tweening shapes" on page
Click any frame in the tween's frame span and select Motion from the Tween pop-up menu in
5.
the Property inspector (Window > Properties).
If you modified the size of the item in step 4, select Scale to tween the size of the selected item.
6.
Drag the arrow next to the Easing value or enter a value to adjust the rate of change between
7.
tweened frames:
To begin the motion tween slowly and accelerate the tween toward the end of the
animation, drag the slider up or enter a negative value between -1 and -100.
To begin the motion tween rapidly and decelerate the tween toward the end of the
animation, drag the slider down or enter a positive value between 1 and 100.
By default, the rate of change between tweened frames is constant. Easing creates a more
natural appearance of acceleration or deceleration by gradually adjusting the rate of change.
To rotate the selected item while tweening, select an option from the Rotate menu:
8.
Select None (the default setting) to prevent rotation.
Select Auto to rotate the object once in the direction requiring the least motion.
Select Clockwise (CW) or Counterclockwise (CCW) to rotate the object as indicated, and
then enter a number to specify the number of rotations.
Note: The rotation in step 9 is in addition to any rotation you applied to the ending frame in step 4.
If you're using a motion path, select Orient to Path to orient the baseline of the tweened element
9.
to the motion path. (See
