In a Java extension I want to track the room of a user that disconnects from the server (e.g. by closing his browser window). My extension receives an InternalEventObject of type "userLost". The SFS docs say that this event has a parameter called "roomIds" of type int[].

But all get from this parameter is an array of 2 objects. There is no way I can cast this into an int or Integer. I wonder what kind of information this object holds? (If I print out the contents of an object[] which holds ints for testing in another file I get int values, which I can cast as ints. Not in this case, all I see is something like "[I"

Here's what I have:

Code: Select all

public void handleInternalEvent(InternalEventObject ieo)
{
      //how can I retrieve the room information form the following expression?
      ieo.getTypedObject("roomIds")[0];

Any idea how I can retrieve th room of the lost user? Thanks.

I would use a different code:

Code: Select all

public void handleInternalEvent(InternalEventObject ieo)
{
	int[] roomIds = ieo.getObject("roomIds");
	int userRoomId = roomIds[0];
	
	// more code here...
}

hope it helps

I had a similar problem, and ended up solving it the long way by setting a "currentRoomId" user variable when a user enters a game room, which I then read when the userLost event goes. I'm sure this is a waste of resources though, and I will have to clean it up later.

What would be the content of the roomIds[] array? Is the roomIds[0] the last room the user joined?

Well,
there's no specific intention to keep a chronology or order of joining but I guess that this is implicit.
Since a List is being used in the User object, the returned array maps exactly that list and so the last element would also correspond to the last joined Room.
