Hm, quick follow-up, am I doing this correctly? This version seems more straightforward but it doesn’t compile, it claims “None of the overloads could convert all argument types”:
FTestChild1 TC1;
FTestChild1* testChildStruct = Cast<FTestChild1*>(TC1);
if (testH) {
GEngine->AddOnScreenDebugMessage(-1, 5.f, FColor::Red, TEXT("Merry christmas!"));
}
