FLASH CS3 242 User Guide See also "Create symbols" on page 208 "Break text apart" on page 270 "Tweened animation" on page 239 Create a motion tween by using the Motion Tweening option 1 Click a layer name to make it the active layer, and select an empty keyframe in the layer where you want the animation to start. 2 To create the first frame of the motion tween, do one of the following: • Create a graphic object with the Pen, Oval, Rectangle, Pencil, or Brush tool, and then convert it to a symbol. • Create an instance, group, or text block on the Stage. • Drag an instance of a symbol from the Library panel. 3 Create a second keyframe where you want the animation to end, and leave the new keyframe selected. 4 To modify the item in the ending frame, do any of the following. To tween the color of elements other than instances or text blocks, use shape tweening: • 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). 5 Click any frame in the tween's frame span and select Motion from the Tween pop-up menu in the Property inspector (Window > Properties > Properties). 6 If you modified the size of the item in step 4, select Scale to tween the size of the selected item. 7 To produce a more realistic sense of motion, apply easing to the motion tween. To apply easing to a motion tween, use the Ease slider to specify an easing value for each motion tween you create, or use the Custom Ease In/Ease Out dialog box to more precisely control the speed of the motion tween. Drag the arrow next to the Easing value or enter a value to adjust the rate of change between 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. • To produce a more complex change in speed within the tween's frame span, use 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 while tweening, select an option from the Rotate menu: • 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.
