Hello all
i
I have strange ( or not ) connection error
When i try to connect the server which is running from my xCode . and Iphone app is running from xcode also .
The line :
if (enet_host_service(client, &event, 1000) > 0 && event.type == ENET_EVENT_TYPE_CONNECT)
Dosn't pass and jumps to :
enet_peer_reset(peer);
BUT when i run this code both from my desktop as simple client/server app , every thing is working just fine .
here is the code which i take from some internet site .
notice i set the HOST to be my Mac : echo $HOSTNAME
mybe this is the problem and the iPhone can't connect my Mac .. i dont know
how can i check this ?
i also found this old post which somehow related
http://www.gamedev.net/topic/601017-resolved-simple-enet-program-fails/
i tried to change the connection address to every thing i could think about
localhost , hostname , ip's from
ifconfig -a
f
