Description

This event is called whenever a user enters a chat channel.

• It is called when users themselves or another user enters the channel.
• It is also called when the users themselves reconnect to the channel.
• A channel is removed from the server if it has been empty(0 members) for 30 seconds. In this case, the GetGroupChannelList() method must be called to load a new channel.

In order for an event to be called, the message sending/receiving method must be called.

Note on the IP assignment issue in data communication environments

You may experience a connection error, due to the mobile IP address assignment issue, when connecting via a data communication network, such as 3G, LTE, or 5G.
It is a common issue that affects not only BACKND Chat, but also other services such as banking applications.
Instruct users who inquire about not being able to connect to the chat server to follow the steps below to renew their mobile IP addresses and resolve their issues.

• Unable to connect to the chat server
  Upon the call of JoinChannel, the user should be connected to the channel after an automatic call of the  OnJoinGuildChannel  method; however, the  OnJoinGuildChannel  is not called and there has been no response for a continuous period.

• Solutions

  • Turn on the airplane mode for 20 - 30 seconds, turn the mode off, and use the device.
  • Use the device after resetting the network
    iOS: Settings > General > Reset > Reset Network Settings
    Android: Settings > General management > Reset > Reset network settings
    * Note that resetting the network will also reset all network settings, including Wi-Fi and Bluetooth.

Example

//First way
Backend.Chat.OnJoinGuildChannel = (JoinChannelEventArgs args) =>
{
    Debug.Log(string.Format("OnJoinGuildChannel {0}", args.ErrInfo));
    //When entered successfully
    if(args.ErrInfo == ErrorInfo.Success)
    {
        // When you connect 
        if(!args.Session.IsRemote)
        {
            Debug.Log("Connected to channel");
        }
        //When another user connects
        else
        {
            Debug.Log(args.Session.Nickname + " connected");
        }
    }
    else
    {
        //When an error occurs
        Debug.Log("An error occurred while entering. : " + args.ErrInfo.Reason);
    }
};

//Second way
Backend.Chat.OnJoinGuildChannel += (args) => {
  // Same logic as the first way
}
