ptg 256 Chapter 9 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. 4 3 2 1 Snap, Sync, Orient to path, and Scale Rotate Edit 3 From the Library of Wow! eBook ptg Chapter 9 Animating with Classic Tweening 257 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. 3 2 1 No Easing Ease Out Ease In 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. Most of the motion is applied to the end frames so the object appears to slowly accelerate. 3 From the Library of Wow! eBook ptg 258 Chapter 9 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 Motion. Select the symbol instance to receive the copied motion tween. Click the Edit menu, point to Timeline, and then click Paste Motion. The frames, tween, and symbol information are inserted to match the original copied tween. 4 3 2 1 2 1 3 Motion pasted to instance From the Library of Wow! eBook ptg Chapter 9 Animating with Classic Tweening 259 Paste Motion Tween Properties Select the frames in the Timeline with the motion tween you want to copy.

Click the Edit menu, point to Timeline, and then click Paste Motion Special. Choose from the following settings: ◆ X or Y Position. Pastes how much to move in the X (horizontal) and Y (vertical) direction. ◆ Horizontal or Vertical Scale. Pastes the ratio between the current and the natural size in the horizontal (X) or vertical (Y) direction. ◆ Rotation And Skew. Pastes the rotation of the object. ◆ Color. Pastes the color values of the object. ◆ Filters. Pastes the filter properties of the object. ◆ Blend Mode. Pastes the blend properties of the object. ◆ Override Target Scale or Rotation and Skew Properties. Select to override the existing scale, or rotation and skew properties of the object. Clear to paste the properties relative to the target object. Click OK. 6 5 4 3 2 1 6 5 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 From the Library of Wow! eBook ptg 260 Chapter 9 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. Changing the Length of a Tween Add Frames to a Tween Click anywhere except the last keyframe on a motion or shape tweened framespan to place the playhead. ◆ To add multiple frames, select multiple frames in the Timeline. Click the Insert menu, point to Timeline, and then click Frame. TIMESAVER Press F5 to add frames. 2 1 1 Frame is added to tween span. Duration of other tweens is maintained.

Click the Edit menu, point to Timeline, and then click Remove Frames. TIMESAVER Press Shift+F5 to subtract frames. 2 1 1 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.
