Introduction
In the previous Chapter you learned about motion tweening.
In this Chapter, you’ll learn about classic tweening. Tweening
is an animation technique that creates the necessary in-
between frames based on a starting and ending frame. A
motion tween uses one object instance over the entire span
along with property keyframes to create a tween, while a clas-

graphic symbol to display in a property keyframe.

Classic tweening can only be applied to instances of symbols. When applying classic tweening
to groups or text objects, Flash automatically converts them into symbols and stores them in
the Library. When this happens, they appear in the Library named as Tween 1, Tween 2, etc. It is
a good idea to convert them into symbols as the tweening is applied. When managing large
projects with many assets it can become confusing to have assets named in this generic way.
Of course you can always rename them by selecting the field in the Library and typing in a new
name.
If your classic tweened animation doesn't behave as expected, there are a few things you
can check. If the object disappears when you play the animation and only re-appears on the
end keyframe, you may have more than one object on the keyframe. Make sure that only one
object, or instance, is on each keyframe in the tweened span. Also, make sure that both
instances are of the same object. Flash cannot motion tween two different objects. To "morph"
different shapes into each other you must use shape tweening.
Working with Classic Tweening
When classic tweening is applied to
groups or text objects, Flash automatically
converts them into symbols and names
them incrementally in this generic fashion.
A dotted line in a tween span indicates that there is a
problem with the tween. Makes sure there is only one
instance (the same instance) on each keyframe.
