Normal' and 'Hit. @note When receiving an overlap from another object's movement, the directions of 'Hit.

I am converting my project from Ue4 to Ue5 and have discovered that destructible meshes have been replaced by chaos and geometry collections. For events when objects have a blocking collision, for example a player hitting a wall, see 'Hit' events. Using a tag on my enemy and player seem to be working. I have two actors, one if the player character, the other an NPC. How to differentiate and have you can use tags => tag the player pawn with “Player” and check if OtherActor has the “Player” tag; you can use cast => cast your OtherActor in the class of your pawn/player.
