How to inquiry the nearest actor?

RE #1:
Thank you. I searched this from the year 2022 and this image was enough to make what I needed.

GetAllActorsOfClass is acceptable due to how UE4 handles it; remains largely performant. Still doesn’t scale well with large worlds and should be avoided. Any other GetAllActors… nodes are not performant whatsoever and should be avoided.

UE4.27.2:
Is GetAllActorsOfClass with Tag - more performant than GetAllActorsOfClass?

I want to use it on checkpoint Actors. I’ll have about 5 of that exact Class in a level. And I only want to GetAll with a certain tag (which is activated when checkpoint reached).
So is GetAllActorsOfClass with Tag - performant for me in a giant level (1000 other Classes) but only 5 of the Checkpoint Actor Class? Ty

Just an update, 4.27 has a new node to do most of this. " Find Nearest Actor", you will still need to feed it an array of actors from find by tag or other means. But then you will get back closest actor and distance.

Thank you. I ended up using this. (Unless someone tells me the first graph pic is more performant than the new Epic node.)

Before I searched for this thread, I tried to type in Get “nearest” > didnt find.

1. I had to uncheck context specific, Then type in “Find Nearest.”
2. Or add a GetAllActorsOfClass with Tag > drag off the Output Actors > type Find Nearest, and that worked to replace the old code:
