I have looked into the BSD Socket programming and researched the forum but still could not resolve my issue…Here is the thing

void APizzaPizzaCharacter::Connect(){
FSocket* Socket = ISocketSubsystem::Get(PLATFORM_SOCKETSUBSYSTEM)-CreateSocket(NAME_DGram, TEXT("default"), false);
FString address = TEXT("127.0.0.1");
int32 port = 6666;
FIPv4Address ip;
FIPv4Address::Parse(address, ip);
auto addr = ISocketSubsystem::Get(PLATFORM_SOCKETSUBSYSTEM)->CreateInternetAddr();
addr->SetIp(ip.GetValue());//setIP
addr->SetPort(port);
if (!Socket->Bind(*addr)){
if (GEngine){
GEngine->AddOnScreenDebugMessage(-1, 5.f, FColor::Yellow, "Faied to bind socket");
}
}
else{
if (GEngine){
GEngine->AddOnScreenDebugMessage(-1, 5.f, FColor::Yellow, "Socket connect succesuflly");
}
}
Socket->Close();
}

I am running this Connect() in a default myCharacter.cpp. The ISSUE is that, despite the debug message shows socket is connected, the server, which is another program I wrote in C++, did not respond or receive its connection. The server is running on a winsock2. Please help me with that!! I have been working on it for days without progress…Thank you very very much!!
You are not sending any data. Datagram (UDP) sockets are not “connected;” they just send data to a given address/port when you tell them to. That address/port will then, hopefully, receive the data, most of the time, assuming it is listening on that address/port and is also a UDP socket, and assuming that a route exists between the sender and the receiver (which, on the same machine, should be true
Dear all,
I’m really new to UE4 and I would need your help. I’m trying to move an object on a scene by receiving it’s desired position and orientation from an external program. Rama’s TCP solution it’s really nice and it seems the way to go. I was able to put the code con a custom Player Controller Class and it compiles fine, but since I’m really a newbie here I don’t know how to proceed further. How can I actually run the code and use the received data to make an object move? I understand that I need something like a Pawn and use it with my custom PlayerController, but how can I link the two things?
Hi marlo3_14, I know this is a bit old, but I’m new to UE4 and am trying to do exactly what you were talking about here (updating a Pawn’s position according to external data stream from another program). I wanted to know if you had succeeded, and what you used if possible. For now, I have managed to have a functional listening server thanks to Rama’s tutorial (with a few modifications since I’m using UE4.18) and I’m about to go to the next steps. Are there any issued that I should be aware of ? Thanks for your help !
