The pick closest suggestion is for less than specific question.
The overlapping at offset suggestion is for a specific use case.
I feel like you guys didn't get what we are requesting or I'm missing something?
the pick by closest by itself it doesn't work as LOS check as it picks only one object and also you need to make extra events to check the distance to simulate if it's inside the LOS Range
The overlapping at offset you need to make a 360 degrees check at offset to detect any enemy as you could have one enemy at the top RIght and another one at the bottom left for example or more on different Angles, the point you guys missing is the LOS check when it detects it picks multiple enemies in one Pick and they can be at any Angle:
SO to replicate the LOS for what you guys saying has to loop every tick 360 degrees to check all the Angles by checking overlapping at offset Angle by Angle and pick by pick
The same thing you loop 360 degrees trowing Ray cast rays at all 360 angles to detect enemies, also here you pick only the first object that intersects no the one is behind
