USING FLASH CS4 PROFESSIONAL
Timelines and Animation
Right-click (Windows) or Control-click (Macintosh) any frame in the tween’s frame span and select Create Classic
Tween from the context menu.
If you created a graphic object in step
2, Flash automatically converts the object to a symbol and names it
tween1
.
6
If you modified the size of the item in step 4, select Scale in the Tweening section of the Property inspector to tween
the size of the selected item.
7
To produce a more realistic sense of motion, apply easing to the classic tween. To apply easing to a classic tween,
use the Ease field in the Tweening section of the Property inspector to specify an easing value for each classic tween
you create. Use the Custom Ease In/Ease Out dialog box to more precisely control the speed of the classic tween.
Drag the value in the Easing field or enter a value to adjust the rate of change between tweened frames:
To begin the classic tween slowly and accelerate the tween toward the end of the animation, enter a negative value
between -1 and -100.
To begin the classic tween rapidly and decelerate the tween toward the end of the animation, enter a positive value
between 1 and 100.
To produce a more complex change in speed within the tween’s frame span, click the Edit button next to the Ease
field to open the Custom Ease In/Ease Out dialog box.
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.
8
To rotate the selected item during the tween, select an option from the Rotate menu in the Property inspector:
To prevent rotation, select None (the default setting).
To rotate the object once in the direction requiring the least motion, select Auto.
To rotate the object as indicated, and then enter a number to specify the number of rotations, select Clockwise
(CW) or Counterclockwise (CCW).
Note:
The rotation in step 8 is in addition to any rotation you applied to the ending frame in step 4.
9
If you’re using a motion path, select Orient To Path in the Property inspector to orient the baseline of the tweened
element to the motion path.
10
To synchronize the animation of graphic symbol instances with the main Timeline, select the Sync option in the
Property inspector.
Note:
Modify
> Timeline
> Synchronize Symbols and the Sync option both recalculate the number of frames in a tween
to match the number of frames allotted to it in the Timeline. Use the Sync option if the number of frames in the animation
sequence inside the symbol is not an even multiple of the number of frames the graphic instance occupies in the document.
11
If you’re using a motion path, select Snap to attach the tweened element to the motion path by its registration point.
Create classic 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.
