Ok here's something that sounds simple.

I have mc A moving slowly across the screen.
I would like to detect it's position x and y, and then at a certain coordinate(let's say x= 200 and y=300) attach mc B(which is just floating around) to attach itself to and follow mc A movement.
And then at some point attach mc B to attach itself to another mc(C).

Is it also possible to attach mc B to a certain pixel (xy) on mc A (or C).

Any ideas

Cheers
