hostId | Host ID associated with this connection (retrieved when calling NetworkTransport.AddHost). |
address | IPv4 address of the other peer. |
port | Port of the other peer. |
exceptionConnectionId | Set to 0 in the case of a default connection. |
error | Error (can be cast to NetworkError for more information). |
int A unique connection identifier on success (otherwise zero).
Tries to establish a connection to another peer.
The error parameter will return a non-zero value if an error occurs, this value can be cast to a NetworkError for more information.
NetworkTransport.Connect can still fail despite returning a non-zero connection id, so make sure to poll NetworkTransport.Receive or NetworkTransport.ReceiveFromHost to listen for events. If everything is OK a NetworkEventType.ConnectEvent will be returned.
