What is "From Sweep" and "Sweep Result"?

More specifically, in OnComponentBeginOverlap node. I’ve searched for it but couldn’t find any information or examples. What this is for and how to use it?

Sweep refers to a hit with another collision unit.

For example if you use “Set actor location” you can use sweep to check if there is a collision between the current location and the intended location.

I’m not entirely sure what exactly those two properties do and don’t have an engine nearby but there should be a tooltip if you hover over the output pin.
