ConnectionConfig.AddChannel

Parameters

Returns

byte Channel id, user can use this id to send message via this channel.

Description

Adds a new channel to the configuration and returns the unique id of that channel.

Channels are logical delimiters of traffic between peers. Every time you send data to a peer, you should use two ids: connection id and channel id. Channels are not only logically separate traffic but could each be configured with a different quality of service (QOS). In the example below, a configuration is created containing two channels with Unreliable and Reliable QOS types. This configuration is then used for sending data.

using UnityEngine;
using UnityEngine.Networking;

public class ExampleScript : NetworkBehaviour
{
    void Start()
    {
        ConnectionConfig myConfig = new ConnectionConfig();
        int reliableChannelId = myConfig.AddChannel(QosType.Unreliable);
        int unreliableChannelId = myConfig.AddChannel(QosType.Reliable);

        //......

        //NetworkTransport.Send(hostId, connection, reliableChannelId, data, data.Length, out error);      //sends data via Reliable channel
    }
}
