How do I hide an object behind transparent wall?

Object in a red frame is fully transparent

If you put it over a black sprite, it's part also goes transparent and you can clearly see the background.

The idea would be to have a drag-and-dropabble glass, looking through which parts of sprites disappear (setting a sprites opacity to 0 on contact with the glass would not work at all)

Thanks in advance.

but..... it does not make sense!

if it's transparent you have to see what's behind otherwise is NOT transparent

I suppose I should have been clearer *sigh*

I need the transparent object to overlap ALL other objects of it's layer and make the background (next layer after) visible.

Pls help

I have no idea what you really ask. But i guess that you have to explore the blend modes.
