I'm trying to make this small game whereby 50 "stick" is genrated and randomly place over the stage. The player will try to collect all the stick back.

Here is how it sld work:
-stick randomly place on stage
-player click, sitck disappear

But I wanna restict the player to pick only stick in the "top". Top meaning it not overlap by other stick. And that the problem, how should i detect it?

I consider using depth, but again, the one with the higest depth might not be the only topest. There will surely be more then 1 topest sitck at anytime.

What should i do to get what i wan? Please Advice..
