Hey there,
There could be several approaches to this, especially if you are willing to do some C++ work. But here is one option: How to get location of closest enemy pawn? - #3 by ThompsonN13
Essentially, you could get closest actors and then use grt overlapping actors to filter for the enemy AI
- Find Nearest Actor | Unreal Engine Documentation
- Get Overlapping Actors | Unreal Engine Documentation
If you have a navmesh, you may be able to use simple move to location or simple move to actor. But I don’t think you can use the other AI nodes unless your player is possessed by an AI controller.
