How do you use simple blueprint interfaces?

I’ve tried to use a blueprint interface to move a pawn, “FighterBlu”, to the location of an actor, HexBlu".

While playing, the “Event Actor Clicked On”, in HexBlu, works (i.e. it fires to the interface when clicked). However, the “Event Interface Fn”, in FighterBlu, isn’t triggered. I don’t understand where I’ve gone wrong.

Because you calling Fn event in HexBlu to itself instead FighterBlu

Thanks for the reply . Are you saying that the “target” of “Interface Fn” in “HexBlu” should be FighterBlu? If so, how can you reference FighterBlu inside HexBlu? I thought the point of interfaces was that you didn’t need to?
