Format
Topic(T,Addr,Master,Keys)
When
Called when a message is received from another server by using world.Export(). If a file is expected, world.Import() may be called to get it. The return value of Topic() will be passed back to the remote server.
Args
T: The topic text string specified by the remote server (everything following ? in the URL).Addr: The address of the remote server.Master: 1 if remote server is the server which started this one.Keys: List of keys belonging to users who are logged in on the remote server
Default action
The topic “ping” returns a true value (number of players plus one), which may be useful for telling if a server is alive. The topics “Reboot” and “Del” will call world.Reboot() and world.Del() respectively if the message was sent by the master server.
world/Topic(T)
if(findtext(T,"shout:") == 1)
world << copytext(T,7)This example allows other servers to send this server topic text of the form “shout:msg” and will broadcast the message to all the players in this world.
The Keys argument is either null, or a list of user keys. Any keys in the list are logged in to the remote server.
Danger
Always validate the input in
Topic()calls to make sure it’s correct and the query you’re recieving is legitimate.
