Creating Animations 213

To make the current frame an Overlay frame:

• In the Frames tab, click on the icon at the bottom of your chosen

frame. Click again to revert back to a normal frame.

You can make background and overlay frames by right-clicking a

frame, and from Properties, enable Background or Overlay. Check

the Normal radio button to revert the frame to a normal frame

again.

Working with Keyframe animation

When compared with Stopframe animation (see Getting started with animation

on p. 207), Keyframe animation offers a more powerful and efficient animation

technology—it's a valuable time-saver as it saves having to declare every frame,

letting your computer do the hard work! Essentially, the technique lets you

create only user-defined keyframes through which objects animate, with each

keyframe containing Key objects which can be assigned a position, rotation,

attributes, etc. Intermediate steps between Key objects are created automatically

and produce a smooth professional-looking inter-object transition (this is called

Tweening); Tweened objects are created as a result. You won't see these

intermediate steps showing tweened objects by default, but they exist

transparently between key objects throughout your animation.

The Storyboard tab is the workspace for laying out your animation "story" in a

chronological keyframe-by-keyframe sequence (from left to right). On export,

your animation will play in this direction. Using the above "bee" animation in

the tab illustration as an example, the bee is animated, while the sun and

"Buzzzz" text remain static objects.

By adding objects (bee and sun) to a starting keyframe it's possible to

automatically copy (or more correctly run forward) those objects forward when
