So I go over and make it decent.
Character Only Spawns Device
Device has Sphere and Other Cosmetics. On overlap calls the container widget.
Here is viewport of radar, I made it a bit fancy using a mesh , some materials design on it.
Radar Widget have only 2 functions that inserts and entry or removes and Device actor controls it. Once set it passes owner, widget parent and target actor.
Also contains all UI Structure
RadarEntry_WBP does everything standalone for itself. It has a pulsate animation and an event inside.
Simply Ontick calculates its distance on parent widget, Set rates for beep event and pitch, change some brush color depending on distance.
Results
This is much better way of doing it.
