as3 flash getChildAt(0).someMethod access

Question

I can do this getChildAt(0).alpha = 0;

But this throws an error getChildAt(0).gotoAndStop(2);

How do I access a movieclip's methods using the display list array?

Answer 1

getChildAt does not return a movieclip, so you need to cast it first, using the as keyword:

(getChildAt(0) as MovieClip).gotoAndStop(2);
