Dynamically accessing nested movie clips in flash actionscript 2

Question

I have a nested movie clip instance that I want to access. The path to the movie clip is defined by two variables ( similar to a row and column).

I am already dynamically accessing the parent movie clip like this:

eval("row" + ActiveRow)

Now I want to access one of row(#)'s children called let(#) dynamically.

Here are my best guesses at accomplishing the task (neither one works):

var i:number;

eval("row" + ActiveRow + ".let" + i) or eval("row" + ActiveRow).eval("let" + i)

Thanks a lot for your effort and possible solution..

Answer 1

you could try

this["row" + ActiveRow]["let" + i]

What would be better though is if when you create the instances you put them in an array... so maybe

var rowClips : Array = [];

for (var i : int = 0; i < 10; i++)
{
     var row : MovieClip = this.createEmptyMovieClip("row" + i, i);

     rowClips.push(row);
}

you can then call it by

rowClips[i];

Obviously depending on the situation there could be different logic to adding your MovieClips to an Array but essentially it's a much nicer way to store references to your MovieClips.
