Flash CS3 - bug in mask layer ?

Apr 10, 2008 6:19 AM

Hi,

I have created mask layer with single MC cosisting of couple of instaces of
another MC. This is a set of growing squares. The problem is that only first
instance gives mask effect. Rest of instances are not used to. Does anybody
knows what is wrong and how to workaround this (most likely) bug ? I would
like to avoid creating one masking MC consisting of e.g. 100 layers - with
teened growing sqare on each layer but in different position. Wiser is just
to create one MC consisting of many instances of another single MC.

Second example describing issue.
Mask layer contains shape tween which consist of 3 keyframes. Masked layer
contains single keyframe at first frame with one MC. This MC restarts when
middle keyframe in the mask is played. It seems that masked MC (on different
layer obviously) is recreated when playhead meets keyframe in mask layer in
tweened shape. In the same moment our MC stopped beeing visible for AS3
under given name as well.

It seems that if mask layer contains more complex animation then basic shape
move/scale then masking stops working properly. Is it bug in Flash palaer or
am I doing mistake?

Regards,
Marek

    As long as I'm understanding the issue correctly, this is a long standing "Flashism" (not saying it's right or desirable, but something that has required a workaround for a very long time). See if you can use nesting to get around the issue (the animation will restart when keyframes are encountered), I'll send this issue in for review. It's possible it has something to do with Player, although I can't find any concrete information on this to know for sure.

    Yes, i worked around the issue by placing it into a movieclip but i don't like it coz its on a separate timeline. Well i guess i have no other choice Thank you very much for your response, really appreciate it.
