Resolved the server and client should have the same NetworkBehaviour instances

Hi Guys,

Just running through my first Networking tutorials for Mirror and got an error:

Code (CSharp):

1. Found no receiver for incoming Command [-411249099] on Unit(Clone), the server and client should have the same NetworkBehaviour instances [netId=8].
2. UnityEngine.Logger:Log (UnityEngine.LogType,object)

4. Mirror.NetworkIdentity:HandleRemoteCall (int,int,Mirror.MirrorInvokeType,Mirror.NetworkReader,Mirror.NetworkConnectionToClient) (at Assets/Mirror/Runtime/NetworkIdentity.cs:1096)

11.  

I have units spawning fine when I have a client+Host and then when I add a second client they only update one frame and cannot use the movement script:

Code (CSharp):

1. public class UnitMovement : NetworkBehaviour
2. {
3.     [SerializeField] private NavMeshAgent agent;
4.     [SerializeField] private Camera mainCamera;
5.    
6.     #region Server
7.     [Command]
8.     private void CmdMove(Vector3 position)
9.     {
10.         if (!NavMesh.SamplePosition(position, out NavMeshHit hit, Mathf.Infinity, NavMesh.AllAreas)) { return; }
11.         agent.SetDestination(hit.position);
12.         Debug.Log("Moving to " + position);
13.     }
14.     #endregion
15.     #region Client
16.     public override void OnStartAuthority()
17.     {
18.         mainCamera = Camera.main;
19.     }
20.  
21.     [ClientCallBack]
22.     private void Update()
23.     {
24.         if (!hasAuthority) { return; }
25.  
26.         if (!Mouse.current.rightButton.wasPressedThisFrame) { return; }
27.  
28.         Ray ray = mainCamera.ScreenPointToRay(Mouse.current.position.ReadValue());
29.  
30.         if(!Physics.Raycast(ray, out RaycastHit hit, Mathf.Infinity)) { return; }
31.  
32.         CmdMove(hit.point);
33.         Debug.Log("Sending " + hit.point + " to Server.");
34.     }
35.     #endregion
36. }

and my unit script:

Code (CSharp):

1. using Mirror;
2. using System.Collections;
3. using System.Collections.Generic;
4. using UnityEngine;
5. using UnityEngine.Events;
6.  
7. public class Unit : NetworkBehaviour
8. {
9.     [SerializeField] private UnityEvent onSelected = null;
10.     [SerializeField] private UnityEvent onDeselected = null;
11.  
12.     #region Client
13.     [Client]
14.     public void Select()
15.     {
16.         if (!hasAuthority) { return;}
17.         onSelected?.Invoke();
18.     }
19.  
20.     [Client]
21.     public void Deselect()
22.     {
23.         if (!hasAuthority) { return; }
24.         onDeselected?.Invoke();
25.     }
26.     #endregion
27. }
28.  

I have followed the tutorials exactly unless I miss configure something in the inspector. So I can send requests for movement but the CmdMove() never gets executed.

 

Ah see, I must have deleted NetworkTransform component at some point. How Bazaar I did that?
