How can I see the type in BP equal which type in c++

I want to pass a parameter in bp to c++ how can I see th type in bp is which type in c++

What you mean by pass parameter from BP to C++, all blueprint a class which is inherited from some class in c++, so you can actually only get their parent class in c++. You can not get any parameter which created in BP unless it from BP’s parent class.

So let say YourPawn is BP from YourClass you can check this by

YourPawn->IsA(YourClass::StaticClass());

ok ,thank u very much
