How to get user by id and disconnect user?

Zone zone = (Zone)event.getParameter(SFSEventParam.ZONE);
User user = zone.getUserById(1);
this.getApi().disconnectUser(user,ClientDisconnectionReason.IDLE);

Answer 1

You are getting user by id = 1 , the id may be not valid , the id that SFS gives for every user may be vary , it's not like an array that starts from 0 , it may change every time some one connect or disconnect , when a player connect to sfs , it takes an id , when he disconnect , some one else may take it , you can get user id by this :

        Collection<User> users =  getParentExtension().getParentZone().getUserList();
        while (users.iterator().hasNext())
        {
            int id = users.iterator().next().getId();
        }

and then use disconnect function to disconnect him or just user the user from collection to disconnect him.
