The Basic Ping System is not just a basic ping system, it's a nice basis because of its clear default set up, expanding on the system isn't convoluted. The system is replicated, it features both Item pinging and location pinging. It can be used on both static actors and physics actors. The blueprint logic is written neatly into a macro library allowing for extremely quick migration and implementation into other projects.
