After you fine-tune a motion tween, you can copy and paste the frames, tween, and symbol information to another object.. Copying and Pasting a Tween Copy and Paste a Motion Tween Select

Classic tweens can be fine-tuned in the Property Inspector When a tweened frame is selected, a number of options are enabled that you use to add complexity to your motion path It is also where you remove

an applied classic tween Set the tween to deal with scale, set rotation direction and frequency, or apply inertia by easing in or out of the motion Additionally, you can set orientation and snapping when using a motion guide In Flash, you can customize easing in or out of a motion using the Edit button in the Property Inspector

Adjusting Classic

Tween Properties

Set Classic Tween Properties

Click the Window menu, and then

click Properties to open the

Property Inspector

Select a keyframe with motion

tween applied

Choose from the following

settings:

◆ Scale Check this when you are

tweening scale changes

◆ Rotate Sets the direction and

frequency your object rotates

◆ Orient To Path Use this when

you have applied a motion

guide layer This keeps your

object parallel to the guide

relative to its center point

◆ Sync This synchronizes the

animation contained in the

symbol with the Timeline that

contains it Use this when your

symbol's Timeline is not an

even number of frames

◆ Snap Check to snap the

object's registration point to a

motion guide

◆ Edit This button allows you to

create custom ease in and

ease out transitions

To remove a classic tween, click

the Insert menu, and then click

Remove Tween.

Set Ease Properties in a

Classic Tween

Click the Window menu, and then

click Properties to open the

Property Inspector

Select a keyframe with motion

tween applied

Click the Ease field, and then

select the setting to set the speed

at which your object eases in or

out of its motion

A positive value eases in, a

negative value eases out A zero

value evenly distributes motion

across each frame

Motion is evenly distributed across frames.

Most of the motion is applied to the beginning frames

so the object appears to slow down as it stops.

After you fine-tune a motion tween, you can copy and paste the frames, tween, and symbol information to another object When you paste a motion tween, you can also specify the motion tween properties you want to apply, such as X and Y position, horizontal and vertical scale, color, filters, and blend You can also override target scale, rotation, and skew properties If you want to use a motion tween as ActionScript 3.0 in the Actions panel or other code-specific location, you can use the Copy As ActionScript command

Copying and Pasting

a Tween

Copy and Paste a Motion Tween

Select the frames in the Timeline

with the motion tween you want to

copy The frames you select need

to be on the same layer However,

the selection can span a tween,

empty frames, or two or more

tweens

Click the Edit menu, point to

Timeline, and then click Copy

Select the symbol instance to

receive the copied motion tween

Click the Edit menu, point to

Copying Motion As ActionScript 3.0

In addition to copying motion tweens in the Timeline, you can also copy motion tweens to the Actions panel or use them as ActionScripts To accomplish this task, you use the Copy Motion As ActionScript com-mand This command copies the properties that define a motion tween

in the Timeline as ActionScript 3.0 These properties include Position, Scale, Skew, Rotation, Transformation Point, Color, Blend Mode, Orientation To Path, Cache As Bitmap Setting, Frame Labels, Motion Guides, Custom Easing, and Filters After you copy the properties, you can apply them to another symbol in the Actions panel or in the source files for the Flash document that uses ActionScript 3.0 To copy a motion tween as ActionScript 3.0, select the frames in the Timeline with the motion tween you want to copy, click the Edit menu, point to Timeline, click Copy Motion As ActionScript 3.0, type the name of the instance to attach the motion tween to, and then click OK Flash gener-ates ActionScript for the specific instance name The code appears on the Clipboard for use in the Actions Panel or other place

For Your Information

Tweens in Flash are editable after they have been created You can continue to change their properties and position in the Timeline, and Flash redraws the tweened frames To change the length of a motion or shape tween (that is, the time it takes to complete the tween), you can add or remove frames in the framespan Essentially you are adjusting the amount of frames Flash uses in its calculation of the tween Adding frames means it takes longer for the transformation to happen, while deleting frames shortens the time

Tween span is reduced by one frame.

Did You Know?

If no layer is selected, the entire

Timeline increases or decreases when

you add or remove frames To

con-strain this action to one target layer,

lock all other layers you don't want to

affect, or simply select the frame in the

tween you want to adjust

Tweens with more frames will be

smoother The more frames you add to

a tween, the smoother the animation

plays, because Flash has more frames

to split the motion between However,

if you add too many frames the

anima-tion may move so slowly that the

illu-sion of movement could be hampered

It is best to experiment with the length

of a motion or shape tween and the

frame rate of your Flash movie until

you get the results you are looking for
