4.5. Animating Rotation
Problem
You want an element to rotate during a motion tween.
Solution
Either apply rotation to the tween or use the Free Transform tool to rotate the instance(s) manually.
Discussion
Flash offers two different ways of rotating elements in a motion tween: you can use the Rotation attribute of a tween to apply rotation as a part of the tween, or you can use the Free Transform tool to rotate one or both instances at the beginning and end of the tween.
To set a motion tween’s Rotation setting, select the keyframe in which the tween begins, and use the Property inspector to specify the type/direction of rotation and the number of revolutions. When adding rotation using the Rotation setting of a tween, you can enter only integers. That is, Flash forces you to specify rotation in complete 360° increments. You can specify None to prevent rotation; Auto to rotate in the direction requiring the least motion; CW to force Flash to rotate the instance clockwise; or CCW to force Flash to rotate the instance counterclockwise. This approach to rotating elements is ideal for spinning animations, such as the spinning of a basketball through the air.
When adding rotation using the Free Transform tool, which is discussed in Recipe 1.32, you can rotate only between 1° and 359°. That is, if you spin an element five times with the Free Transform tool, and leave it facing in the same direction it was originally facing, Flash won’t even register that it has been rotated. Therefore, use ...
