Interface Function is not called from C++

Assuming your interface has “Execute_Event1” in it; you need to cast the Actor to your interface and then call the Actor’s Interface method:

void UCallGlobalEvents::Call_Event1(struct Struct1 Meta, struct Struct2 InData)
{
TArray<AActor*> Actors;
UGameplayStatics::GetAllActorsWithInterface(GWorld, UGlobalEvents::StaticClass(), Actors);
for (AActor* Actor : Actors)
{
UGlobalEvents* CastedActor = CastChecked<UGlobalEvents>(Actor); // GetAllActorsWithInterface already did the ImplementsInterface check for us.
CastedActor->Execute_Event1(Actor, Meta, InData);
}
}

Thanks for the response. If I Try to compile this its failing:

if i change UGlobalEvents to IGlobalEvents its compiling but crashing on execution.

But anyhow i did a cross check and implemented the following code in a blank C++ actor and that is working fine:

 
TArray<AActor*> Actors;
  UGameplayStatics::GetAllActorsWithInterface(GWorld, UGlobalEvents::StaticClass(), Actors);
  for (AActor* Actor : Actors)

  {
  if (Actor->GetClass()->ImplementsInterface(UGlobalEvents::StaticClass())) {
  IGlobalEvents::Execute_Event1(Actor, Meta, InData);

  }
  }

So my Problem must be something else. Is a Class in a Gameinstance behaving any different in that regard ? because that’s where the call comes from.
