Hi guys,

As most of you know, I'm making an MMORPG entitled Exodus Online.  The fact that my game is an MMO means that I need repeating network calls to get the other user's locations.  If I do this in the loopIteration() method, the program becomes far too slow.  So my plan is to make the network calls repeat as fast as possible but in a different thread.  The network call affects the scenegraph, BTW.  Is this "safe"?  Is there a built-in way to do something like this in Xith?  I know that there is talk about thread-safeness, but I never looked into it too deeply, thinking that it didn't concern me.  Guess I was wrong  .

So, any problems with that?  Does anyone have any other ideas?  I am open to anything.

Well, there is the UpdatingThread class, that is exactly for this. You can create it with your RenderLoop as a constructor parameter, to synch the game-time. Then invoke the begin() method with a "true" parameter, to let it run in a separate thread.

Then you could use a ScheduledOperation to apply the changes to the scenegraph, that you've computed in the other thread. But don't create a new ScheduledOperation instance each time, but use a non-persistent ScheduledOperation instance, that you reuse each time.

If UpdatingThread doesn't have enough features, you could also use OperationSchedulerImpl, which is an UpdatingThread extension.
