UDP receives nothing
Hi. I use a standard Winsock server for my game and i have a problem to comunicate whith Esenthel sockets in UDP mode.
1rst, i dont undersand differance between CreateUdp() and CreatePeer(port). Maybe a peer is an UDP with Addr inside ??
I tryed both and my server send perfectly packets to my bot application (bot in dos console + winsock) and my receiver Thread in my game doesn't receive anything !!!
Init:
Code:
s_recoi.createUdp(); // or createPeer(port); same problem !
_srv_addr.ip(ip);
_srv_addr.port(port);
Thread:
Code:
s_recoi.receive(_srv_addr, buff, sizeof(buff));
console->add(buff); //console is my class to draw text in a custom console
Srv:
Code:
//s ia a DATAGRAM sock binded
ctrl = sendto(s, buff, sizeof(buff), 0, (SOCKADDR*)&srvAddr, sizeof(srvAddr));//sendto
Maybe an idea ? thanks in advance.

Re: UDP receives nothing
createUdp creates a standard UDP socket,
and
createPeer creates UDP socket and then binds it to receive data from any IP using specific PORT
please take a look at network socket tutorial, maybe this will help

Re: UDP receives nothing
Thx for explanation. I created a Peer on my client and unbind my server.
It works perfecly but i have two questions about network only:
- Can i launch two clients on the same computer ? I dont think i can bind two socks on the same port :/
- Will the users have to nat their UDP ports if behind a firewall to play the game ? UDP server in the client app :/
sorry! it's a noob question !

Re: UDP receives nothing
Hi,
Full networking support isn't implemented yet so I can't help you with that.
As stated here in the FAQ <!-- m --><a class="postlink" href="http://www.esenthel.com/en/engine/about.html">http://www.esenthel.com/en/engine/about.html</a><!-- m -->
you need to implement the networking manually.
As I'm currently focusing on other things (improving World Editor).
