hi..
i had the same probs some days ago, so i could tell u what solved them in my case.
Darkfrog gave me the hint to use the GameTaskQueueManager, if u try to manipulate the SceneGraph form anywhere outside the single-threaded OpenGL-Thread.
So i tried to follow this hint, and started to use the GTQM in create() and remove() of the SyncObjectManager.
public Object create(SynchronizeCreateMessage scm)
{
Callable<AbstractAvatar> createAvatarCall = new Callable<AbstractAvatar>()
{
public AbstractAvatar call() throws Exception
{
//create a remote Object for the representaion of another user's Avatar.
final AbstractAvatar av = new AvatarFactoryImpl().create(AvatarFactoryImpl.NOUSERAVATAR);
av.addToScene(VB3DBaseGame.getInstance().getGui().getRootNode());
EntityManager.getInstance().addEntity(av);
return av;
}
};
try
{
//add the Callable, which should add the internaly create the remoteObject and add it to the sceneGraph
//to the updateQueue of the GameTaskQueueManager.
// .get() returns a Future containing the remoteObject.
return GameTaskQueueManager.getManager().update(createAvatarCall).get();
}
catch (InterruptedException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
catch (ExecutionException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
public boolean remove(SynchronizeRemoveMessage srm, Object obj)
{
if (obj instanceof NoUserAvatar)
{
System.out.println("CHAT-SYNC-OBJECT-MANAGER: remove() was Called by ID:" + srm.getPlayerId());
System.out.println("CHAT-SYNC-OBJECT-MANAGER: SyncObject to remove: " + srm.getSyncObjectId());
final AbstractAvatar av = (AbstractAvatar) obj;
Callable<Boolean> removeAvatarCall = new Callable<Boolean>()
{
public Boolean call() throws Exception
{
try
{
LuaManager.getInstance().destroyScript(av.getScript());
return av.removeFromScene();
}
catch (ConcurrentModificationException e)
{
e.printStackTrace();
return false;
}
}
};
try
{
return GameTaskQueueManager.getManager().update(removeAvatarCall).get();
}
catch (InterruptedException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
catch (ExecutionException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
return false;
}
else
{
System.out.println("CHAT-SYNC-OBJECT-MANAGER: remove() was Called by ID:" + srm.getPlayerId());
System.out.println("CHAT-SYNC-OBJECT-MANAGER: SyncObject to remove: " + srm.getSyncObjectId());
System.out.println("CHAT-SYNC-OBJECT-MANAGER: but SyncObject was no instance of NoUserAvatar");
return false;
}
}
Hope this helps in your case as well.
