Using Touch to select the topmost sprite object

How do I write the conditions to select only the topmost sprite object when they happen to overlap? My code at the moment is On Touch sprite object destroy. So, when two different moving sprite objects happen to overlap, I only want to select the topmost sprite and destroy it. With my present code, both overlapping sprites are destroyed.

Any help given will be much appreciated.

Condition:

-On touch "Object"

--Object pick top most (Under "Z order" category)

Actions:

-Object Destroy

But it doesn't work when the overlapping sprites are of different objects. The pick top applies to instances of objects, not the top object when the below sprite is of a different object.

In that case, create a family (let's call it "destroyableFamily" and include all objects that could be destroyed into this family. And have this instead:

Condition:

-On touch "destroyableFamily"

-- "destroyableFamily" pick top most (Under "Z order" category)

Actions:

• "destroyableFamily" Destroy
