Accessing Childten MCs with MouseEvents in AS3

Question

Hi,
I now have working code that creates a mask of about 2,700
children on a 650 by 450 image using a container to hold all the
children's MCs.
Can anyone provide any help as to how I can access these
children at once with a MouseEvent so that I could for instance
change the alpha value of a child shape when the user rolls over it
with their mouse.
I have attahced the code to this post.
Thanks in advance for any of the help provided as I've been
learning to use AS3 from AS2.
Best,
Justin

Answer 1

i was just thinking that i wonder if the clips are on stage?
and it looks like the problem may be in the loop declarations i
think what you want should be more like:
for(var i=0; i<original_mc.height / commaTile_mc.height;
i++)
but at the time of the loop the value of commaTile_mc.height
cannot be determined - you need to use a constant value there,
whatever the height and width of the actual tile mc are - use a
number.
i think the lines you have there are 'not' executing the
loop.
