(SOLVED) Messaging System with FMessageEndpoint doesn't work in Shipping Build

Development Programming & Scripting C++

I’m pretty certain that the MessageBus system is for tools/development only, it’s not something meant for use in a live product. If you look in MessagingModule.cpp, right at the top:



#ifndef PLATFORM_SUPPORTS_MESSAGEBUS
    #define PLATFORM_SUPPORTS_MESSAGEBUS !(WITH_SERVER_CODE && UE_BUILD_SHIPPING)
#endif

No message bus is created (See StartupModule()) unless that define is true. The only platform that seems to overrides this is Hololens, but even that looks like a temporary solution based on the code comments in HoloLensPlatform.h:



//@todo.HoloLens: Fixup once sockets are supported
#define PLATFORM_SUPPORTS_MESSAGEBUS                        1

EDIT: There is a TCPMessagingModule and a UDPMessagingModule that seems to not care about that define.
