Thanks for the post.

@jooj

checking if (child) wont guarantee whether its a a movie clip or not.
and hence

var child:DisplayObject = getChildThatMightBeMovieClip();

if (child is MovieClip) {
with (child as MovieClip) {
trace(numChildren);
trace(currentFrame);
}
}

stands out….

I usually use nested “with”, for my object arrays.

if (child) {

}
