Thank you Nimtrix
It�s a great solution. My problem was that the objects where both of the same type and family.
I have a Dropspot with a Item over it, for example a rope.
In another i have two sticks, another item
In another i have a sprite with a fish
So if you drop the rope over the sticks they are joined, so rope is destroyed and the sticks became something new.
But if you drop the rope over the fish nothing happens.
I�m not interested in the DropSpot where the item is. I needed to know the item over which the item drops over.
So finally i have
item is overlapping dropspot
item pick nearest to (Drag.X, Drag.Y)
which is really confuse :)
Tomorrow i will prepare an example :).
Thanks for your time and interest.
