I'm working on a grid-based game
and sometimes , I create some instances directly on others ...
I would like to delete instances DIRECTLY at the bottom , let's take an example
I have an instance (1) and I create another instance ontop of the other one (2)
(2) is deletable when
(1)X and Y = (2)X and Y
and not otherwise
But I may have other instances scattered on the screen
so I need to pick (1) -Bottom Instance- and delete it even if there's a third or four instance , taking note of the rule above
How would I go about picking 1 and other instances that follow the rule ?
Thanks for reading and have a nice day
