Why isnt my BPI event (Blueprint Interface) firing/triggering? How to pass a Bool?

Thanks for that picture to help. Your first post answered it for me, so I gave you credit.

  1. In the yellow box below, is it correct that that Class Node is a wildcard for any Character Movement component that Overlaps? (Meaning only Character BPs with Movement Comps can trigger the Overlap, but not Bullets. And I am using a semi-wildcard so that I dont need to use Cast To.)
  2. And is it performant? (Meaning I only want to check for Characters/AIs that may pass thru the Navigation box of the Spline BP, which should be under 20 at a time. And I can further refine by checking if the Character/AI even has the BPI implemented.)
