Sync a cube in UNet

Unity Engine

So I’m trying to learn the ropes of UNet after years of using legacy networking, I’ll be looking into other solutions soon after I give UNet its fair shot :stuck_out_tongue:

I’m used to the minimal component setup and prefer doing it all through script. I’ve been referencing the MasterServer example and what I can from the documentation.

I have a basic scene setup:
NetworkHandler script on a gameobject
CubeUpdate script on a cube, along with a NetworkIdentity checked as ‘server only’

This cube needs to be a scene object. I heard there were bugs with [ClientRpc] on scene objects, but then I also read it was fixed in 5.1.3, which I am on.

I believe the reason it isn’t working is I see no observers listed when connected and viewing the inspector of the cube. Most likely related to NetworkServer.SpawnObjects() doing nothing on the client, I have to manually turn the game objects on.

using UnityEngine;
using System.Collections;
using UnityEngine.Networking;

public class NetworkHandler : NetworkBehaviour
{


    NetworkClient myClient;

//called by ui button
    public void startServer()
    {
     
        NetworkServer.Listen(4444);
        print("Server started");
        NetworkServer.RegisterHandler(MsgType.Connect, OnServerConnect);

        //only working on server?
        NetworkServer.SpawnObjects();

    }
//called by ui button
    public void connect()
    {
        myClient = new NetworkClient();
        myClient.Connect("localhost", 4444);
        print("connected");
        myClient.RegisterHandler(MsgType.Connect, OnClientConnect);   
    

    }

    void OnServerConnect(NetworkMessage netMsg)
    {
        //works
        print("Client connected");    

    }

    void OnClientConnect(NetworkMessage netMsg)
    {
        //manually turn on scene objects...
        //no observers though
        NetworkIdentity[] nis = Resources.FindObjectsOfTypeAll<NetworkIdentity>();

        for (int i = 0; i < nis.Length; i++) {
            nis[i].gameObject.SetActive(true);
            nis[i].RebuildObservers(true);
        }
    }





}

using UnityEngine;
using System.Collections;
using UnityEngine.Networking;

public class CubeUpdate : NetworkBehaviour {


    //goal move a cube in the editor on the server and
    //see it move on the client window...


    [ServerCallback]
    void Update () {   
     
        print("sending");
        RpcUpdateCubePos(transform.position);  
 
    }


    [ClientRpc]
    void RpcUpdateCubePos(Vector3 pos)
    {
        //doesn't print
        print("got update");
        gameObject.transform.position = pos;

    }
}

Solved it as I was in the process of writing my own layer on the LLAPI and loaded up this project one last time :p, for anyone else having this issue:

Don’t be like me and not read what ‘Server only’ means on the NetworkIdentity, as I assumed it was marking it as server authoritative. I guess they’re authoritative by default.
