Question Network SceneManager

Hi!
I have big problems to change my scene from my lobby to the game scene.
In my first scene (MainMenu) I have my Network Manager.
From that I click on a Multiplayer Button and switch the scene with:

Code (CSharp):

1. SceneManager.LoadScene("Scene_Lobby");

to my Lobby Scene.
In my Lobby Scene I have a gameobject with a ProjectSceneManger Script attached to it with this code:

Code (CSharp):

1. public override void OnNetworkSpawn()
2.     {
3.         if (IsServer && !string.IsNullOrEmpty(m_SceneName))
4.         {
5.             Debug.Log("OnNetworkSpawn");
6.  
7.             NetworkManager.Singleton.SceneManager.OnSceneEvent += SceneManager_OnSceneEvent;
8.             var status = NetworkManager.Singleton.SceneManager.LoadScene(m_SceneName, LoadSceneMode.Additive);
9.             Debug.Log(status);
10.  
11.             CheckStatus(status);
12.         }
13.        
14.         base.OnNetworkSpawn();
15.     }

I try to start my game from the the lobby with

Code (CSharp):

1. NetworkManager.Singleton.StartHost();

for the host and

Code (CSharp):

1. NetworkManager.Singleton.StartClient();

for the client,
but the debug from the OnNetworkSpawn methode always prints:

Code (CSharp):

1. Failed to load Scene_Game with a SceneEventProgressStatus: SceneEventInProgress
2.  

The docs say:

• This is returned if you attempt to start a new scene event (loading or unloading) while one is still in progress

but I don´t understand why there should be a loading process.
Can anyone help me?

 

It sounds like LoadScene is called too early but I'm sure why that is, you could try moving it to Start instead.

If that doesn't work try subscribing to SceneManager.sceneLoaded and the NetworkSceneManager callbacks to shed more light on the subject.

Code (CSharp):

1.        SceneManager.sceneLoaded += (scene, mode) =>
2.         {
3.             Debug.Log($"SceneManager scene: {scene.name} mode: {mode}");
4.         };

Code (CSharp):

1.         NetworkManager.Singleton.SceneManager.OnLoad += OnLoad;
2.         NetworkManager.Singleton.SceneManager.OnLoadComplete += OnLoadComplete;
3.         NetworkManager.Singleton.SceneManager.OnLoadEventCompleted += OnLoadEventCompleted;
4.         NetworkManager.Singleton.SceneManager.OnSceneEvent += OnSceneEvent;
5.         NetworkManager.Singleton.SceneManager.OnSynchronize += OnSynchronize;
6.         NetworkManager.Singleton.SceneManager.OnSynchronizeComplete += OnSynchronizeComplete;
7.         NetworkManager.Singleton.SceneManager.OnUnload += OnUnload;
8.         NetworkManager.Singleton.SceneManager.OnUnloadComplete += OnUnloadComplete;
9.         NetworkManager.Singleton.SceneManager.OnUnloadEventCompleted += OnUnloadEventCompleted;

 

Thank you very much!
I found out, that I have loaded also a scene in the ApprovalCheck
After I changed that, the host is changing the scene correctly, but the connected client not.
Do I have to call the NetworkManager.Singleton.SceneManager.LoadScene method from the client also, or
what could be wrong here?

 

The client scene change should be automatic if Enable Scene Management is ticked on the NetworkManager (it is by default) and the connection is approved. If you subscribe to NetworkManager.Singleton.OnClientConnectedCallback on client/server it will be called on client connection.

 

Now it is working!
I changed so much back and forth, that I can´t say what exactly the reason was.
Thank you so much cerestorm!
