That's not how I do it. When the player reaches the end, it will receive
a playStopped message which you can trap. That way you don't need to
keep checking on its progress. The message is sent to the player object
itself, not to the card it's on, though you could put a handler anywhere
in the hierarchy. I have this in a player script:
And then you can put a "doPlayStoppedStuff" handler in the card or stack
to actually do whatever needs doing when the playback is done. This may
mean you need to break up your big handler into two separate pieces, but
this method is cleaner.
A second alternative is to set some callbacks on the player (see
"callbacks" in the dictionary.) That will allow you to send messages at
any defined point during playback, and you can have a handler that
responds to those messages. If you only need to know when the playback
is finished, just set a single callback at the end.
To prevent the player from stopping during card changes, I put the
player in a separate substack which isn't visible. It just sits there
and plays stuff while the main stack is operating. I don't know if that
will work for you. In my case I don't need a controller so it doesn't
matter if the player isn't visible. Mine just does background audio, and
the user turns it on/off with a button on the main card.
Mp3 files work fine for me. If you are getting a duration of zero it
means the file wouldn't load. What happens if you use the player's
property inspector to select the file from disk instead of setting it
with a script? Does it play then? If so, then it's probably a glitch
somewhere while constructing the file path.
