I was wondering if it's possible to make it where you can interact with object behind and overlay or an opaque object

For example, I have a black tile with opacity of 50%
floating above the players layer. I want to be able to for example pickup an object.

You double posted. Check out mouse_opacity. If set to zero, the mouse acts as if the object is not there.
Sorry about the double post, thanks for the reply. I was not aware of that variable. very simple thank you
