How to find an actor that has called specific event?

So my game’s map is entirely made with many amount of one single blueprint(object), and because of that it’s easy to call every actors on the map but I can’t find the way to choose a specific actor and call it. Can somebody help me with this?

(Sorry for bad English)

There are several options to do that.

A posibility is to use tags in your objects, so when you look for a specific one, you can check if the tag is the one you are looking for.

Another posibility is to asign a variable inside your blueprint, where you can asign some kind of id number to each object. then you can look for it,

Of course to look for a specific one, you can do a get all actor of class, then iterate between all and look for your tag or id.
