Sending netobjects with NetEvents (TGE 1.3)

I wrote this to send complete objects to the client. If I have a smaller update such as a single field, I will use commandtoclient. If you plan on using simobject pointers you will probably want to use the notify features so you dont crash when you delete the items.

I probably missed some stuff so back up your code before you use this!

class SendItem : public NetEvent
 {
    typedef NetEvent Parent;
    NetObject *object;

    SimObjectId objectId;
    bool validObject;
    public:
    SendItem(NetObject *obj=NULL);

      ~SendItem()
      {
      }

      void pack(NetConnection* ps, BitStream *bstream)
      {    
      NetObject *object = (NetObject *) Sim::findObject(objectId);  
            
         if(bstream->writeFlag(object != NULL))
         {
            S32 classId = object->getClassId(ps->getNetClassGroup());
            bstream->writeClassId(classId, NetClassTypeObject, ps->getNetClassGroup());
            object->packUpdate(ps, 0xFFFFFFFF, bstream);
         } else Con::printf("object is NULL");
      }

      void unpack(NetConnection* ps, BitStream *bstream)
      {
         if(bstream->readFlag())
         {
            S32 classId = bstream->readClassId(NetClassTypeObject, ps->getNetClassGroup());
            if(classId == -1)
            {
               ps->setLastError("Invalid packet.");
               return;
            }
            object = (NetObject *) ConsoleObject::create(ps->getNetClassGroup(), NetClassTypeObject, classId);
            if(!object)
            {
               ps->setLastError("Invalid packet.");
               return;
            }
            object->unpackUpdate(ps, bstream);
            validObject = true;
         }
         else
         {
            object = new NetObject;
            validObject = false;
         }
      }

      void write(NetConnection *ps, BitStream *bstream)
      {
         if(bstream->writeFlag(validObject))
         {
            S32 classId = object->getClassId(ps->getNetClassGroup());
            bstream->writeClassId(classId, NetClassTypeObject, ps->getNetClassGroup());
            object->packUpdate(ps, 0xFFFFFFFF, bstream);
         }
      }
      void process(NetConnection *conn)
      {
          NetObject * obj = new NetObject;
          obj = object;
          obj->registerObject();
          Con::executef(2, "onItemReceived", Con::getIntArg(obj->getId()));
       } 
 
   DECLARE_CONOBJECT(SendItem);
};
IMPLEMENT_CO_CLIENTEVENT_V1(SendItem);

SendItem::SendItem(NetObject *obj)
{
 mGuaranteeType = Guaranteed;
 if(obj)
    {
    objectId = obj->getId();
    } 
    object = NULL;
}
      
ConsoleMethod( NetObject, send, S32, 3, 3, "obj.send(%client)"
			  "Send a gameitem to the client.")
{
   NetConnection *conn;
   if(!Sim::findObject(argv[2], conn)) {
         Con::printf("NetObject.send: object does not exist");
      return false;
      }
   conn->postNetEvent(new SendItem(object));
}

in script I did this (i added a name field in netobject so i could replace the old objects) :

function onItemReceived(%obj)
{
echo("Item "@%obj.name@" received");
// replace the old object if there is one
   if(isobject(%obj.name))
   %obj.name.delete();
   %obj.setname(%obj.name);
}
