Pick by UID then check collision not working

I am having difficulty understanding the problem here. I am passing an UID that exists (checked multiple times) and then try to check if that particular instance is overlapping another object. It does not detect collision when i use the pick by UID.

"Pick by UID" picks a single instance. All subsequent conditions operate only on that picked instance. Therefore "Square overlaps square" only tests whether the instance overlaps itself, which isn't a useful thing to check, and in this case is always false.

If you want to test other instances ignoring the picking, add the object type to a family, and test if it overlaps the family instead. This works because families have independent picking in events.

Ahh!

Thanks for the tip!
