Create object from class?

Hi, I am following the code from :

here

to get UDP communication working. The code compiles fine, but I am stuck on this instruction:

"Then in the editor just create an object with the UDPNetworkingWrapper class. "

The UDPNetworkingWrapper is a c++ class, that is in Content/c++Classes. I cannot seem to drag it into the Blueprint to get a reference, I have tried creating an Object variable and using that, but the inputs will not take it. How should I be doing this?

Thanks!

Solved. I need UCLASS(BluePrintable), instead of UCLASS().
