Figure 5-4: A simple motion tween that includes scaling Onion skinning shows all the frames outlined

7 If you want to rotate the object during the tween (in addition to any rotation you create in Step 4), select CW (clockwise) or CCW (counterclockwise) from the Rotate drop-down list in the Properties panel and then enter the number of rotations in the Rotation Count text field To test your animation, click the first keyframe and press Enter or use the Controller to rewind and play your animation You can accelerate or decelerate the speed of the tween To accelerate from beginning to end, enter a value between 1 and 100 in the Ease text field in the Properties panel To decelerate, use a value between 1 and 100 See Figure 5-4 for an example of a ball that moves along a diagonal line The ball also becomes smaller, so it appears to recede in the distance as it moves

To tween along a path that isn t a straight line, you need to draw the path on a guide layer (See Book IV, 4 for the steps to create a guide layer) Your animation is on the guided layer (the layer with the animation on it) that is associated with the guide layer (the layer that has the path that the animation follows on it) Figure 5-5 shows an example of a motion tween along a path

To create an animation that moves along a path, follow these steps (which start just like the steps for simple motion tweening): 1 On your animation layer, insert a keyframe where you want the animation to start To add a keyframe, right-click the frame to the left of where you want to create a keyframe and choose Insert Frame from the contextual menu 2 Click the keyframe and create or import the object or objects (symbol instance, group, or text) you want to animate 3 Insert a keyframe where you want the animation to end 4 Select the range from keyframe to keyframe by clicking the first keyframe and dragging to the last keyframe, or click anywhere between the two keyframes 5 From the Tween drop-down list in the Properties panel, select Motion 6 In the Properties panel, select the Snap check box to snap the object to the path 7 If you want the object to rotate in the direction and angle of the path, select the Orient to Path check box

8 Right-click the object s layer and select Add Motion Guide The new layer is added The layer is labeled Guide, and the object s layer is indented beneath it 9 On the guide layer, draw your path using the Pen tool 10 Click the first keyframe of the object s layer and drag the object by its registration point (a small plus or circle) to the beginning of the path until the registration point snaps to the path 11 Click the last keyframe of the object s layer and drag the object by its registration point to the end of the path until the registration point snaps to the path 12 Press Enter to play the animation If you need to change your path, use the Macromedia Flash editing tools to edit the path that you created You can use the Selection or Subselection tools to edit the path (See Book IV, 2 for details on editing graphics) The guide path isn t visible in the published movie However, you often don t want to see the path even in your document, so you can more easily visualize the animation Just click the eye column of the guide layer to hide it

If you want your objects to change shape, you need shape tweening, often called morphing Unlike motion tweening, shape tweening works only with plain vector objects, usually ones that you create with the Macromedia Flash drawing tools You can t shape tween a symbol instance, text, or a group unless you break it apart by choosing Modify Break Apart To turn text into shapes, choose Modify Break Apart twice The first time only breaks apart the text into individual letters The second time you choose Modify Break Apart, you create shapes from the individual letters However, remember that you can have only one animated object on a layer You can break apart text once and then choose Modify Timeline Distribute to Layers to put each letter on a separate layer If you want to shape tween the letters, break apart each letter a second time
