Clumping things together

1

I have these movieclips on stage, called Seekers. What I’m trying to do is say “If these Seekers touch each other, they should clump together” Now, I have them in a larger array with other elements and also their own array.

What I tried to do was have a loop nested in a loop of two different indexes.

public function checkSmash()
        {
            var c = 0;
            var n = 0;


            while (c<seekerList.length)
            {
                if (seekerList[c] is Seeker)
                {
                    while (n<seekerList.length)
                    {

                        if (seekerList[c].hitTestObject(seekerList[n])
                        {
                            //I don't know.
                        }

                        n++;
                    }
                }
                c++;
            }
        }

My problem is this:
I don’t know how to express the “clump together” part of it.
I don’t think my double loop will work right. It would act twice for each Seeker whereas I only want it to act once.

If anyone could help me out that would be great. Thanks.
