I have a movie in which I have a "Mask arrangement." The
arrangement is that I have a Mask layer with several "cutouts."
That layer is masking the layer below it which has only a single
movieclip. I position the movie clip under a particular cutout so
that it shows, then do some other stuff with it. Here's the trick:
At a certain point, I have that small movieClip execute an
attachMovie and pull another movieClip from the library. I *want*
it to be "under the masked layer" so that this new movieClip also
is able to peek out through the holes in the mask.
However, when I attachMovie the new movieClip appears ON TOP
OF the mask instead of inside being masked. I've tried playing with
various layer management tricks, but it's not working.
I think the issue is that when I add a new movieClip to the
stage, it's either going on a layer BELOW the mask (and the objects
it should be masking)...so don't see it. Or it's going on a layer
ABOVE the mask (and the objects it's masking).
How do I get a new movieClip to appear "inside" the masking
Masks work on MovieClips, not layers, so you have to host the
movieclip you want masked inside another 'holder' movieclip. Apply
the mask to the holder, and then any movieclips you add inside that
holder will be masked.
