I think you’ve got the right ideal. The sphere component would give more dynamic results Even if your game is turned based, you may want your game to recognize another pawn nearby during its current move in case you have ambush mechanics or what not. If the ai being within the radius of another ai only matters between turns then you don’t really need the sphere component and could query nearby ai’s with get all actors from class and compare world locations. You don’t need a trace to do this, just compare their x,y,z and if any of said values are < then X they are within radius.
