Problem to iteract with nested MC

[American horizon]

Hi
i've a mastermc with nested another mc that nest anoher mc

Then i've mastermc--->mc1--->mc2

I've to reach the second child of mc2 and change it alpha propriety, then i've wrote:

mastermc.getChildAt(mastermc.x/450).getChildAt(0).getChilAt(2).alpha=1

but when i launch the program flash give me error
#1061: Call to a possibly undefined method gotoAndStop through a reference with static type flash.displayisplayObject.

Why?

[sakthimani]

try to give their name to specify

like
master_mc.child1_mc.child2_mc.alpha=1

hope it help

You might try assigning those nested MovieClips to variables typed as MovieClips.
That way, the compiler will know that gotoAndStop() is a valid method.

mc1 probably doesn't have (min) three children?

sakthimani's suggestion would be best, but if you really want to use getChildAt, to prevent errors always count the number of children first.

if (mc1.numChildren >= 2) {
mc1.getChildAt(1);
} else {
trace("mc1 doesn't have 2 children or more, but he has " + mc1.numChildren + " children");
}

etc.
