for (TObjectIteratorIn this example, we iterate through all the UClass objects in the game and get a weak pointer to each one. We then check if the pointer is still valid before using it. These examples are commonly used in game development and can be found in the Unreal Engine 4 library.It; It; ++It) { TWeakObjectPtr WeakClass = *It; if (WeakClass.IsValid()) { // Do something with valid class } }
