Dedicated Servers Not Spawning Player Prefabs

#1

Same issue that got called out previously and got a mystery solve, dedicated server no longer spawns player prefab, host version works fine. I’ve tried some variations and haven’t been able to get this working again.

ApprovalCheck and SpawnPlayerDelayed for reference. I threw a bunch of debug messages in there to see if I can figure out where things are getting hung up. Checked the server logs and it gets through the delay, but never past the instantiation of the gameobject.

    private void ApprovalCheck (NetworkManager.ConnectionApprovalRequest request, NetworkManager.ConnectionApprovalResponse response)
    {
        string payload = System.Text.Encoding.UTF8.GetString(request.Payload);
        UserData userData = JsonUtility.FromJson<UserData>(payload);

        // Store data
        _AuthIdViaClientId[request.ClientNetworkId] = userData.UserAuthId;
        _UserDataViaAuthId[userData.UserAuthId] = userData;
        OnUserJoin?.Invoke(userData);

        Debug.Log($"{this.GetType().Name}: {userData.UserName} connected and approved.");

        // If everything is good, create the player (possibly delayed) and approve the response.
        _ = SpawnPlayerDelayed(request.ClientNetworkId);
        response.Approved = true;
        response.CreatePlayerObject = false;
    }

    private async Task SpawnPlayerDelayed (ulong clientId)
    {
        Debug.LogWarning($"{this.GetType().Name}: SpawnPlayerDelayed.");

        await Task.Delay(1000);
        Debug.LogWarning($"{this.GetType().Name}: SpawnPlayerDelayed delay complete.");

        NetworkObject playerInstance = GameObject.Instantiate(_PlayerPrefab, SpawnPoint.GetRandomSpawnPoint(), Quaternion.identity);
        Debug.LogWarning($"{this.GetType().Name}: SpawnPlayerDelayed instantiation complete.");
        playerInstance.SpawnAsPlayerObject(clientId);
        Debug.LogWarning($"{this.GetType().Name}: SpawnPlayerDelayed spawn complete.");
    }

I’m probably going to set things up to use the automated spawning again while poking around for a fix, so that I can keep going :slight_smile:

#2

Hi there,
So it is getting stuck on the line where it instantiates the PlayerPrefab?
Were there any errors logged in the server?
I would guess the player prefab reference might be null? If it’s missing that reference that could break everything.

#3

No obvious errors in the log. I checked for null reference and the references to the player prefab are hooked up. This flow does work as expected for the host gameflow. Spawns the prefab delayed just fine. But switching over to the dedicated server flow it stops somewhere in the GameObject.Instantiate call.

I’ve reverted to the automatic spawning to keep rolling with the course, but I wanted to log this here in case other folks ran into the same issue that seems to have come up a couple of times. Happy to try some variants if it’ll be useful for debugging. Really easy to go back to the delayed setup.

#4

Are you able to share your server logs? Perhaps I can spot something there?

#5

Yeah, I’ll dig up the logs after I roll back my changes.

Well my next thought is that it is stuck in an infinite loop in SpawnPoint.GetRandomSpawnPoint().

Since the code never gets to the next line and doesn’t throw an error.

#8

I’ll poke around in there. Since it works fine for the other pathway, I’m concerned it’s more insidious. I’m still chugging along with the (excellent) course using the automatic spawn workflow.

If I discover anything, I’ll be sure to post a follow up.
