the radar by WPC probably uses that. It's not the best, but it works.Yeah i noticed that in Hud class doesn't seem to work, so i have addded Health tracking into custom GameReplication class.
Health checks in Tick (using custom GameType) and Initiallazing in custom GameType (under Boss preparation in trader time) since i have already altered State MatchInProgress. So i just access to my custom GameRepliaction in HUD.
P.S. I guess it's better than using foreach DynamicActors?
