Symbols, as you learned in the previous lesson, are independent objects that you create that can have their own internal
animation. With JavaScript, you can control the symbol animations to create more sophisticated interactions. For
example, you can create a button that controls a dramatic animated unfurling or closing of a map. Or, you can create a
button that controls the animated expansion or collapse of a more info box. The map and the more info box would be
Symbols that behave independently on the main Timeline.
For your interactive travel slideshow, you’ll add a button at the top of the Stage that, when rolled over, elegantly animates
t
o r
eveal information about the images and Burma.
Adding the button and animated symbol
The button and the animated symbol have already been created for you, and are in the Library ready to use.
1 In the Library panel, expand the Symbols section, and drag the moreinfo symbol to the Stage. Position the moreinfo
symbol at X=200, Y=0.
The moreinfo symbol appears in the Elements and Timeline panels. The short playback arrowheads on the Timeline
show
how long the animation within the symbol lasts (one second long).
2 In the Timeline, click the Playback options for the moreinfo element and choose Stop.
The playback of the internal symbol animation does not play on the main Timeline.
3 Double-click the moreinfo symbol on the Stage and press the spacebar to view the animation within the symbol.
The symbol consists of two short animations. The long horizontal gray rectangle expands, and at the same time, the
clip
ping box of some informational text expands to reveal it.
