The last element, the vertical bar, is built with two rectangles—one for the
background and one for the colored bar. Convert both to a symbol and
animate the bar accordingly. The Stage Timeline now looks like this:
As you can see from the band of gray arrows, all symbol animations start
at the beginning of the composition and stop well before the end. Now
modify the playback behavior of the circular dial hand and the bar anima-
tion. For the latter, move the playhead on the Stage Timeline to 0:00 and set
the Stop playback action to prevent a direct playback. A stop icon appears
on the Timeline, represented by a square within a rectangle. If you move
the playhead to the right to 0:01, the symbol will start, delayed via the Play
playback action. Wherever an internal animation is stopped, the band of
gray arrows disappears from the Timeline.
Unlike the other elements, the round dial hand should start immediately
and rotate twice around its axis. To do this, move the playhead to the end
of the first rotation, or to 0:02 seconds. To achieve a new playback, assign
Play From from the playback actions. Unlike the simple Play command, this
function gives you the ability to specify an absolute position from which
the playback should occur. We use 0:00 so that the playhead of the internal
Timeline within the symbol moves at the beginning, and is then played
back. You can use this technique to easily play back repetitive animation se-
quences as often as needed without having to create them multiple times.
The final Timeline looks as follows:
