I have an issue where I’m getting linker errors…

I have a C++ class that inherits from ACharacter.  
I have two C++ UActorComponents classes. First one I have been working with for several days no problems with RPC calls.

Started to build out the second C++ UActorComponent based class. Compiled fine until I started to add RPC calls… When I did I got an error saying:

```auto
Error	LNK2005	"protected: void __cdecl UBattleComponent::BattleServerRPC_SetAiming(bool)" (?BattleServerRPC_SetAiming@UBattleComponent@@IEAAX_N@Z) already defined in BattleComponent.gen.cpp.obj

```

I’ve deleted all generated files, re-generated visual studio project files… Still getting this same error.

You posted this question under Legacy/UDK Programming and UnrealScript. This section is for programming in Unreal Engine 3 or the Unreal Development Kit, which was a version of Unreal Engine 3. You’ll have better luck with your question if you move it to a different section of the forum.

Oh thank you… I didn’t realize I posted it here. It was very late last night and had been dealing with odd issues for some 8 hours straight.

Thanks!
