GetRecentChat

public BackendReturnObjectGetRecentChat(ChannelType channelType, string channelinDate);
public BackendReturnObjectGetRecentChat(ChannelType channelType, string channelinDate, int limit);

Parameters

Value	Type	Description	Default
channelType	ChannelType	Type of the channel. ChannelType.Public(normal) or ChannelType.Guild(guild)	-
channelIndate	string	Channel's inDate	-
limit	int	(Optional) Number of game information rows to call. Maximum is 30. When set to 0, returns 30	0

Description

This is an asynchronous method that can be called at any time, separate from recent history call events.
Even before entering a channel, you can use this method to view the recent chat history.

In the key value upon return, channel_uuid value is the channel's inDate, and inDate is the time the message is sent.

• Only chats from the public/guild channel are loaded; whispers, announcements, and all chat are not included.
• Up to 30 chats can be loaded for the message history.
• Chats within 1 - 2 minutes might not be loaded.
• The message filter is applied, but not the user block.
• Messages that have passed 48 hours from the time of sending cannot be called.(same as the console's BACKND Chat history viewing).

Example

Synchronous

// Gets the chat channel list.  
BackendReturnObject bro = Backend.Chat.GetGroupChannelList("Group name");

//Gets the UUID of the chat channel.  
string channelIndate = bro.GetReturnValuetoJSON()["rows"][0]["inDate"].ToString();

//Gets the general chat channel's recent chat history using the uuid(only 25)
BackendReturnObject result = Backend.Chat.GetRecentChat(ChannelType.Guild , channelIndate , 25);

for(int i=0; i< result.Rows().Count; i++)
{
string nickname = result.Rows()[i]["nickname"].ToString();
string message = result.Rows()[i]["message"].ToString();

Debug.Log(nickname + " : " + message); 
}

Asynchronous

// Gets the chat channel list.  
Backend.Chat.GetGroupChannelList("Group name", callback => 
{
    if(callback.IsSuccess())
    {
        //Gets the UUID of the chat channel.  
        string channelIndate = callback.GetReturnValuetoJSON()["rows"][0]["inDate"].ToString();

        //Gets the general chat channel's recent chat history using the uuid(only 25)
        Backend.Chat.GetRecentChat(ChannelType.Guild , channelIndate , 25, callback2 =>
        {
            if(callback2.IsSuccess())
            {
                //When successful...  
            }            
        });
    }
});

SendQueue

SendQueue.Enqueue(Backend.Chat.GetGroupChannelList, "Group name", callback => 
{
    if(callback.IsSuccess())
    {
        //Gets the UUID of the chat channel.  
        string channelIndate = callback.GetReturnValuetoJSON()["rows"][0]["inDate"].ToString();

        //Gets the general chat channel's recent chat history using the uuid(only 25)
        SendQueue.Enqueue(Backend.Chat.GetRecentChat,ChannelType.Guild , channelIndate , 25, callback2 =>
        {
            if(callback2.IsSuccess())
            {
                //When successful...  
            }            
        });
    }
});
