[F9] for in loop

[Fall_X]

The for...in loop probably hasn't changed (on a side note, there is supposed to be a new for each loop though), it's the way you access children that has changed. I don't think parentMC[childName] still works, but I haven't tried this. Maybe it works if you set your movieclip-extending-class to dynamic, but that's just a wild guess, and I doubt it.

You can try to loop i from 0 to mc.numChildren, and use mc.getChildAt(i) - not sure if it will work, but it might.

If you want to access a child by name, use mc.getChildByName(name) - however, that's no good for a for...in loop.
