Zoom and fade problem

Question

I have a circle that I want to create a "puls" effect with.
The circle zooms up and fades away, but before it has fade away
complete I need a second circle to start zoom and fade away from
the same place, creating a puls. ( Think of a radiotower sending
out signals). Do I need two circle mc:s or can I work with one?
Allso when I use this code to zoom up the circle, when the function
is complete, the mc stops on full alpha. I want it to loop.

Answer 1

Create a Circle MC and Give
"lingage Id" to that.
Now using
attachMovie create the + symbol
now create a function, say
animateCircle and get a MovieClip Name as Argument.
now paste your transition effect and instead of
circle give the argument value
use
setInterval to call the function with certain interval
to control this use the NumbeofClips, and mcCounter
variables.
i hope this explanation is more than enough to create that
effect.
