Pass variable via blueprintimplementableevent not working

Development Programming & Scripting Blueprint

Hi All

I’m following this;

Jeff Farris’s answer, in order to send a FHitEvent to blueprints from C++. I’m passing by reference to avoid exposing a pointer.

UFUNCTION(BlueprintImplementableEvent, Category = "MyStuff")
void OnCameraTrace(struct FHitResult& RV_Hit);

However, it compiles, but is not accessible in blueprints. It simply doesnt appear in the editor. Has something changed in the engine since that answer was posted?

Thanks!!!

If you’re having this problem, I recommend Rama’s tutorial;

Passing by const solved it.
