The code below uses a LocalConnection to send variables to an
embedded swf. My problem is that I don't understand the need for
some of the code. I found a source online describing the importance
of using a timer to repeatedly send the LocalConnection, but I
don't understand why this is necessary. If I make a function call I
don't keep making the call until the function responds, so why is
this necessary for the LocalConnection? I understand how it works,
but why is it needed?
