Here a small explanation about what the result should be in the term of functionnality (it is a teacher request, so I really want to try it).
For a simulation about the atmosperic CO2 gaz effect, teacher wants the kid to compose an earth situation. A situation is composed of two overlays: a kind of landscape (icy, sandy, vegetation) and a kind of human activity (low, medium, high with a lot of car and factory). I already build a project like that (it is attached so you get a chance to understand what I am trying to explain), but to change the overlay, the kids use two sliders, and the teacher prefers a direct drag and drop of the overlay in a target. So the kids should be able to pick up from the containers an overlay and drop it in a target. Depending on the overlay composition a CO2 gaz effect value is calculated and used to design a visual user feedback for the kid (flooding..)
Not sure it is clear, but looking at the .pr file it may help to understand what is needed

From Etoys is there a way to check when a Morph is dropped in another Morph to later take appropriate action? Moreover when doing the check I would want to decide to accept or not the drop. Is it doable with Etoys tiles?
I didn't see any direct way either. When stuck with problems like these, I imagine how I would tackle such situations with real toys and sensors.
What do those morphs represent? Have you tried using a script to monitor the geometry of the two morphs to check for overlaps?
