Title: Problems with packets #2.
Post by: kapesu8 on July 09, 2012, 01:12:02 pm

I've switched my game to use udp instead of tcp, because you know :P

So I'm testing it over local network and I've faced some problems..

So if we would have a code

sf::UdpSocket socket;
sf::IpAddress SenderAddress;
sf::Packet ReceivedPacket;
unsigned short Port;
if(socket.receive(ReceivedPacket,SenderAddress,Port)==sf::Socket::Done) {
sf::IpAddress SenderLocalAddress = SenderAddress.getLocalAddress();
}

Now would the SenderLocalAddress be the sender's local address or the local host's local address?
Since when I send directly data from the client to server over local network the server receives the data, however when the server tries to response the client doesn't get the data.

And I was just wondering that does it even send it to the right IP?

SenderAddress.getLocalAddress() doesn't make sense. getLocalAddress() is a static function of IpAddress which returns your own local IP address. SenderAddress is the address of the sender.

So senderaddress is the sender's local address already?

Yes.

To get the sender's global address would I need to include it to the packet from client-side?

To be clear: the address that you get is the one that you must use to respond to the sender. You don't need to do anything.
