i am trying to figure out how to use a listener to monitor a movie’s (“objectA”) alpha value.

i am loading a “objectA” into a container movie. there is a close button in “objectA” that tells it to fade to “0”.

i want the listener to monitor the loaded “objectA”'s alpha value, and when it reaches 0, i want the listener to call a function that will unload “objectA” from it’s container.

hope this makes sense.

thanks!
