A game object can only be in one layer. The layer needs to be in the range [0...31]

Hi there, I am making a multiplayer FPS with Mirror.
I am following an old Brackeys tutorial, changing the obselete HLAP to Mirror.

Here is my player prefab window:

On both the client and the host side, I keep getting this message:

(Filename: C:/Users/Useraname/OneDrive/Documents/MultiplayerFPS/Assets/Mirror/Runtime/Transport/Telepathy/Server.cs Line: 82)

A game object can only be in one layer. The layer needs to be in the range [0...31]
UnityEngine.GameObject:set_layer(Int32)
PlayerSetup:AssignRemoteLayer() (at C:\Users\Username\OneDrive\Documents\MultiplayerFPS\Assets\Scripts\PlayerSetup.cs:50)
PlayerSetup:Start() (at C:\Users\Username\OneDrive\Documents\MultiplayerFPS\Assets\Scripts\PlayerSetup.cs:24)

This is

PlayerSetup.cs

:

Code (CSharp):

1. //-------------------------------------
2. // Responsible for setting up the player.
3. // This includes adding/removing him correctly on the network.
4. //-------------------------------------
5. using UnityEngine;
6. using Mirror;
7.  
8. [RequireComponent(typeof(Player))]
9. public class PlayerSetup : NetworkBehaviour
10. {
11.  
12.     [SerializeField]
13.     Behaviour[] componentsToDisable;
14.     [SerializeField]
15.     string remoteLayerName = "RemotePlayer";
16.     Camera sceneCamera;
17.     void Start()
18.     {
19.         // Disable components that should only be
20.         // active on the player that we control
21.         if (!isLocalPlayer)
22.         {
23.             DisableComponents();
24.             AssignRemoteLayer();
25.         }
26.         else
27.         {
28.             // We are the local player: Disable the scene camera
29.             sceneCamera = Camera.main;
30.             if (sceneCamera != null)
31.             {
32.                 sceneCamera.gameObject.SetActive(false);
33.             }
34.         }
35.     }
36.  
37.     public override void OnStartClient()
38.     {
39.         base.OnStartClient();
40.  
41.         string _netID = GetComponent<NetworkIdentity>().netId.ToString();
42.         Player _player = GetComponent<Player>();
43.  
44.         GameManager.RegisterPlayer(_netID, _player);
45.     }
46.  
47.  
48.     void AssignRemoteLayer()
49.     {
50.         gameObject.layer = LayerMask.NameToLayer(remoteLayerName);
51.     }
52.  
53.     void DisableComponents()
54.     {
55.         for (int i = 0; i < componentsToDisable.Length; i++)
56.             {
57.                 componentsToDisable[i].enabled = false;
58.             }
59.     }
60.  
61.     // When we are destroyed
62.     void OnDisable()
63.     {
64.         // Re-enable the scene camera
65.         if (sceneCamera != null)
66.         {
67.             sceneCamera.gameObject.SetActive(true);
68.         }
69.  
70.         GameManager.UnRegisterPlayer(transform.name);
71.     }
72. }

My other scripts are attached below:

There is also a short

PlayerWeapon.cs

script that contains weapon information, however I feel this is irrelevant.

I also can not move on the unity editor. I imagine this is related to this issue, and will be resolved when this issue is.

Does the "RemotePlayer" layer exists in both project's settings?
This error often occur while calling a layer from name an unfortunately doesn't exist in the Project Settings.

 

In the project settings "Tags & Layers" window, both LocalPlayer and RemotePlayer exist as layers, on 8 and 9.

 

Exact same code, exact same error from a 5 years old topic o_o...
https://answers.unity.com/questions/1103260/a-game-object-can-only-be-in-one-layer-the-layer-n.html

 

What does this print?

Code (CSharp):

1. int layer = LayerMask.NameToLayer(remoteLayerName);
2. Debug.Log($"Layer I am trying to assign is: {remoteLayerName}:{layer}");
3. gameObject.layer = layer;

 

Actually a bit concerned by the declaration :

Code (CSharp):

1.  [SerializeField]
2.     string remoteLayerName = "RemotePlayer";

Who know the variable could be different on request.
Could you log it right before the assignment?

Code (CSharp):

1. void AssignRemoteLayer()
2.     {
3.         Debug.Log(remoteLayerName);
4.         gameObject.layer = LayerMask.NameToLayer(remoteLayerName);
5.     }

 

Ah yeah good point. Most likely the string has been changed in the editor or something.

 

I get an error saying 'the name 'remoteLayerName' does not exist in the current context

 

Where did you put this code? It should go in AssignRemoteLayer()

 

I put the three lines in AssignRemoteLayer() and it gives me the same error.

As far as I can tell nothing is printed to the console.

Code (CSharp):

1.     void AssignRemoteLayer()
2.     {
3.         int layer = LayerMask.NameToLayer(remoteLayerName);
4.         Debug.Log($"Layer I am trying to assign is: {remoteLayerName}:{layer}");
5.         gameObject.layer = layer;
6.     }

 

Your code before was already using the variable "remoteLayerName" in that spot, so you must have changed something else in the interim to get that error now.

 

Brackeys !
