<div>gamespy transport service is using udp. <br>
right now one of the player creates socket and just
listens to it, another on is actively trying to connect to
other party, but fails at create_host for some reasons. I
am creating host in the same way on both machines.<br>
<br>
I am testing connectivity on the same machines constantly,
so I dont see any reason why it should work for 3 times in
a row and then wouldnt... and it's a bit weird moment -
creating host, i would expect it to fail when actually
trying to connect<br>

If both your players try to connect at the same time
then they should get through after a retry or two.<br>
<br>
Although there is many types of nat's so it might not
always work.<br>

I am using enet library in conjunction
with gamespy. I use gamespy to create
socket, connect to lobby, select opponent
and do the NAT punch-through. In next step
I close gamespy socket, initialize enet
library and try to create enet host with
same port (in my case I pass ip as empty
string) and then start connection to other
party. It works, but not always. I am
using three computers right now: pc vista,
pc xp and mac osx 10.7.4. On mac sometimes
(not always) I cannot create enet host
(even if i try to create host with
different ports, 100 retries), here's the
code: <br>
<br>
retries = 101; <br>
enet_address_set_host (&enet.gAddress,
ip); <br>
do { <br>
enet.gAddress.port = port; <br>
enet.gHost = enet_host_create
(&enet.gAddress , 1 , 2, 0 ,0 ); <br>
<br>
if (enet.gHost == NULL) <br>
{ <br>
printf ( "An error occurred while
trying to create an ENet
host(%s:%d).\n",ip,port); <br>
port++; // HACK <br>
} <br>
else <br>
printf( "host created.\n"); <br>
} while (enet.gHost == NULL &&
(--retries > 0)); <br>
<br>
Any ideas? <br>
Thank you! <br>
Martin <br>
