To use tweening in Director, you define properties for a sprite in frames called keyframes and let Director change the properties in the frames in between.
To specify tweening properties for a sprite, use the Sprite Tweening dialog box.
A keyframe usually indicates a change in sprite properties. Properties that can be tweened are position, size, rotation, skew, blend, and foreground and background color. Each keyframe defines a value for all of these properties, even if you explicitly define only one.
