Multiple magnet animation

In this video I collect a list of positions from an array of points using the collection controller. Then I passed this list to a magnet controller. Magnet controller generates output for each point in collection and return a list of scalar values.Then using a List controller I managed to find the biggest magnet value and assign that to the height of the box. Notice that when we use combinations of list controller and magnet controller we should use Key-frame maker to animate the result.
