I like using Blueprint Interfaces because they decouple the Blueprints and seem to speed up compile time.

However they aren’t as easy to use as types for example:

GetAllActorsWithInterface - very inefficient because it has to loop over all actors!

SphereOverlapActors - doesn’t support interface filter

FilterArray - doesn’t support interfaces

etc…

Would be really nice to have more support for filtering based on Interface.

Hi cgrebeld,

Thank you for your feedback, we will take this into consideration.

Is this still being taken into consideration? As many times as I tried, using the UInterfaceClassName class when a method takes a UClass* filter class, does not work. Such as if I had a interface named, “UGameplayActor”, and my classes inherit from “IGameplayActor”, using “UGameplayActor::StaticClass()” for the filter class, such as in GetOverlappingActors(), will return nothing. But if I leave out the filter class, and then iterate the list of overlapping actors, then typecast into my “IGameplayActor” interface class, then I have results. I’m currently using UE 4.9.0
