NetworkTransport.Connect

Parameters

Returns

int A unique connection identifier on success (otherwise zero).

Description

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 casted 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.
