Can I create NPC users in Zone Extension's init() method?

[KrinalDhaduk]

I have been trying to create NPC Users initially in extension init() and getting Null Ref. I have posted server trace below that includes logs as well.
It looks like SmartFoxServer instance is null somehow

Hi,
it's not possible to create Users (such as NPCs) in the init() method because Zones are created before the server is completely started up.

To accomplish what you're trying to do you need to add a server side listener for the SERVER_READY event and execute the code that creates the NPCs there.

A quick way to do it would be this:

Code: Select all

@Override
public void init()
{
   addEventHandler
   (
      SFSEventType.SERVER_READY,
      new BaseServerEventHandler()
      {
         @Override
         public void handleServerEvent(ISFSEvent event) throws SFSException
         {
            // NPC code goes here
         }
      }
   );
}


Hope it helps
