How can I remove a child when it reaches a certain frame or frame label?
You need some way of detecting which frame the child is on.
There are probably a few ways of determining that a child is on a certain frame. One would be to have the child dispatch an event when it reaches that certain frame and have a listener assigned for that in the parent timeline.
Another way would be to constantly monitor the child to see what its currentFrame or currentLabel property is, although a currentLabel does not necessarily equate to a certain frame.
