I'm making a drag and drop system. It works, but when two items overlap and you try to grab them, your mouse will pick up both items. What I want to happen is when you pick up an item, it comes to the top layer, and if you click on overlapping area2ds, the mouse picks up the front-most item.
I don't know how to properly explain the issue, so I'll just let you try out the project files:
The only draggable items are the head and the orange ellipse thing.
