Making a function NetMulticast, Reliable throws "already defined" error

Development Programming & Scripting

I’m trying to add networking to my game, but when I try to make a function NetMulticast and Reliable like this:

 UFUNCTION(NetMulticast, Reliable)
 virtual void Dealing();

I get this error:

Error 1 error LNK2005: "public: virtual void __cdecl ASCard::Dealing(void)" (? Dealing@ASCard@@UEAAXXZ) already defined in SCard.cpp.obj C:\Users\Kochab\Documents\Unreal Projects\Spades\Intermediate\ProjectFiles\Spades.generated.cpp.obj Spades

What am I doing wrong?

.h

 virtual void Dealing();

 UFUNCTION(NetMulticast, Reliable)
 virtual void ServerDealing();

.cpp

 void ASCard::Dealing() {
      if (Role == ROLE_Authority)
      {
           ServerDealing();
      }
 }

 void ASCard::ServerDealing_Implementation() {
      ...
 }

Note the addition of _Implementation at the end of the function name. If that isn’t there it will throw the “already defined” error.

I love how it’s totally skipped in the documentation.

Can you spawn actors using multicast? So far it didn’t work for me, and I don’t want to make the spawned actors replicated.
