OnConnection method is the obvious point to place your UI (menus, mainbars, tool buttons) through which the user will communicate to the app. This method is also the place to put your validation code if you are licensing the add-in. You would normally do this before putting up the UI. If the user is not a valid user, you would not want to put the UI into the IDE.

Lobby BBS channel manager

Title Lobby BBS channel manager
Author(s) WangTian
Date 2008/6/24, Doc requirement added LiXizhi. 2008.7.20
File script/kids/3DMapSystemUI/Chat/ChannelManager.lua

Description

Message format 

{ 
   uid = user id, 
   date = send date,
   channelName = channel name that this message belongs to,
   channelColor = text color, [optional]
   text = pure or mcml text,
   name = fullname of the user sending the message.
   JID = JID of the user sending the message. 
}
Please note that in the remote database, we only store three fields {uid, date, content} Hence, uid, date are read exactly as in the remote database. channelColor and channelName are added locally according to local settings when a message is retrieved. text, name, JID are stored as NPL table in content column. Whenever we received the content field from the server, we will decide if it is xml (pure text) or a serialized NPL table string(begins with '{'). If it is table, all table fields are extracted to the message.

Sending message

Usually when we send messages, we usually send a serialized table string containing {text, name, JID}, such as { uid, channelName, content = commonlib.serialize_compact({text, name, JID}); } The text length is limited to 256 characters.

Displaying message in chat window

we will reconstruct an mcml string from available message fields to display a given message. the reconstruction is as below.

[{msg.channelName}] :{msg.text}

We will display 8 messsages at a time in a screen.

Getting latest messages

the way client getting messages from server is based on polling. the polling logic is below - If lastUpdateTime==nil, immediately fetch from the server the lastest 50 messages. - If we have just send out a text, immediately fetch from the server the lastest messages since the lastUpdateTime we will prevent entering text again until either the last update returned or some serverTimeOut(10 s) is passed. - If we have not been sending messages then if chat window is enabled then if the last fetched messages are Not empty update from server again activeUpdateInterval( 1 seconds) after the last fetching result is available or some serverTimeOut(10 s) is passed. else update from server again after activeEmptyUpdateInterval( 5 seconds) after the last fetching result is available or some serverTimeOut(10 s) is passed. end else if the last fetched messages are Not empty update from server again passiveUpdateInterval( 5 seconds) after the last fetching result is available or some serverTimeOut(10 s) is passed. else update from server again after passiveEmptyUpdateInterval( 10 seconds) after the last fetching result is available or some serverTimeOut(10 s) is passed. end end end

Getting already fetched messages

Call the following method to retrieve already fetched messages. It can be called as many times by any other applications. such as the summon mode. It only returns from the local memory. 
   local msgs = Map3DSystem.App.Chat.ChannelManager.GetFetchedMessages({
      channel = nil, if nil it means from all channels,
      afterDate = nil, if nil it means the latest
      pageSize = 50, return the latest number of message after afterDate
   })

Summon mode

Title Summon mode
Author(s) LiXizhi
Date 2008/7/16
File script/kids/3DMapSystemUI/Chat/SummonMode.lua

Description

The idea of summon mode is to select a few from online people. and display their avatars' agent near the current player avatar. In this case, the current user can communicate with agents face to face without compromising other people. The communication, however, is limited to chat and animation. The agent movement is usually AI based such as facing to the speaking character near it.

The procedure is as below - start the summon effects on the current player - make remote requests to selects a given number of uids from a given pool (such as online users and recently BBS speaking users) - find their JIDs from their uids. - for each candidate{ if(avater with JID does not exist) then if(filter(IsFriend or JustSpeaked)) then retrieve its avatar ccs info Create a character using its JID, make it non-persistent. create the agent avatar as agent OPC in the scene. mark the agent with agent head on display Assign agent AI module to the agent OPC. (more info, please see SummonedAgent.lua) end end move the player to a location near the current character. play summon effects and animation on the agent for 2 seconds. }

the context menu for agent includes - teleport to avater of the agent. - private chat. - see profile of its user. - recast as local character. - delete (ban) this candiate

Whenever the user receives or sends a BBS message in public or world channels. it will search in OPC and main player and display head on text for some seconds.

Additional agent functions

Instead of avatars, one can also summon pets from other offline/online players and adopt them in their world. One can right click on an agent and recast(rename) it as a local character.

blocking an agent

call BlockAgent(JID)
