Object

• ClassPrivate Is the UClass of the object instance. The thing you get back when you call GetClass().
• If a object was loaded from “a loader” (FAsyncPackage or LoadPackageInternal) it will have the RF_WasLoaded flag. This can be very useful to use on actors to know if they got loaded from disk or spawned at runtime.
