I am placing structures on my game map via a click event. So when you are ready to put an item down it should not be on TOP of another object.
For example you cannot build 2 towers in the same position.(x)
I can check to make sure that it is not overlapping and that works fine. But if I hover over another structure ( it is not overlapping ) then I can build the structure there : ) So.... basically I need to see if there is another structure BELOW the mouse : )
Any thoughts? Maybe in the morning I will get up and I will see it, but at 1 a.m. it is eluding me :)
