I want some of my custom components to have a sphere or cone shaped indicator when EDITING like the built-in light compnent, is it possible?
in-component no way, at least in BP. Maybe in c++ can be done.
in BP you can create custom construction function, there you can “getOwner” and add sphere or another collision/any other dummy component. Then add this function node in construction script of actor.
For actor just add sphere collision/any other dummy component in construction script
can i make that dummy component editmode-only?
sure, find checkbox “is editor only” if i understood what you want. This checkbox makes component to not be in packaged build
