Syncing object transforms

[araujokth]

Hi,

I was following the instructions on the wiki and also downloaded your example. I setup a scene with a network manager (added the MLAPI component Networking Manager to it), then a cube prefab (added the MLAPI component Networked Object) and then added an HUD object with your NetManagerHud.cs script from your example to do the network configurations.

For some reason, I am getting the error when starting the server:

KeyNotFoundException: The given key was not present in the dictionary.
System.Collections.Generic.Dictionary`2[System.String,System.UInt32].get_Item (System.String key) (at /Users/builduser/buildslave/mono/build/mcs/class/corlib/System.Collections.Generic/Dictionary.cs:150)
MLAPI.NetworkingManagerComponents.NetworkSceneManager.SetCurrentSceneIndex ()
MLAPI.NetworkingManager.Init (MLAPI.NetworkingConfiguration netConfig)
MLAPI.NetworkingManager.StartServer (MLAPI.NetworkingConfiguration netConfig)
NetManagerHud.OnGUI () (at Assets/NetManagerHud.cs:33)

which is the line NetworkingManager.singleton.StartServer(config);

This also happens in the StartClient and StartHost if I press those buttons instead.

Any idea what could be wrong? Tried googling but couldnt really find any help that could be applied here.

I am running Uity 5.6.3p2 (64bit).

Thanks!

This is because you have enabled automatic scene management in the network config. But the scene is not registered as a networked scene. Thanks for reporting this, a proper error message will be added! For now, either disable scene management or register the scene.

Fixed.

Thanks a lot! (I think) I would like to have scene management, so I would like to register the scene.

I was looking in the tutorial page and you say "EnableSceneSwitching has to be set to true and all scenes that are going to be used during Networking has to be registered. The NetworkingConfiguration.RegisteredScenes list has to be populated with all scene names, this a simple security measure to ensure rouge servers don't request client's to switch to sensitive scenes."

In your NetManagerHud.cs I now added the line config.EnableSceneSwitching = true but I couldnt understand what you said afterwards on how I could register a scene and where/how to issue "NetworkSceneManager.SwitchScene(mySceneName);"

[TwoTenPvP]

To Register a scene. Do
myNetworkConfig.RegisteredScenes.Add("myScene1");
myNetworkConfig.RegisteredScenes.Add("myScene2");

And you can call NetworkSceneManager.SwitchScene(mySceneName); anywhere to switch to another registered scene. (Only from server tho)

Got it. I will just have a single scene in each project, so I wont be needing to switch between the scenes, if I got the implementation correctly.

I now got another error which is related to the added channel I believe:

"ArgumentOutOfRangeException: Argument is out of range.
Parameter name: requested qos type doesn't exist: 10
UnityEngine.Networking.ConnectionConfig.AddChannel (QosType value) (at C:/buildslave/unity/build/Runtime/Networking/Managed/NetworkTransportConfig.cs:443)
MLAPI.NetworkingManager.Init (MLAPI.NetworkingConfiguration netConfig)
MLAPI.NetworkingManager.StartServer (MLAPI.NetworkingConfiguration netConfig)
NetManagerHud.OnGUI () (at Assets/NetManagerHud.cs:35)"

[TwoTenPvP]

Seems like the channel we use to send all internal MLAPI messages doesn't exist in Unity 5.6.
Thanks for letting me know. I'll add that to the config.

[TwoTenPvP]

This has been added:
TwoTenPvP@11bd452
Add: UseLegacyChannel = true in your NetworkConfig.

Once again, thanks a lot for reporting these issues. Trying to get the library stable at the moment. Previously I have just focused on features.

[araujokth]

Config? Sorry, I have only started to play with Unity recently and dont know how to get that.

[TwoTenPvP]

The NetworkConfig where you specify all the channels etc?
NetworkingConfiguration

[araujokth]

aha sorry. I am just using the exact same definitions that you have in your example code "NetManagerHud.cs"

[TwoTenPvP]

I have been so busy developing the library that the example has gotten nearly no attention. I am working on a update for it tho.

[araujokth]

No worries! I will just remove all those configurations for now and focus on synching the object transform only!

[araujokth]

Strange. I now commented out all those configurations and still get the error. My server config looks like this:

if (GUI.Button(new Rect(20, 70, 100, 20), "Start server"))
        {
            NetworkingConfiguration config = new NetworkingConfiguration()
            {
                Address = "127.0.0.1",
                Port = 7777,
            };
            config.RegisteredScenes.Add("nw_test_MLAPI");
            config.EnableSceneSwitching = true;
            //config.Channels.Add("PositionUpdates", QosType.Reliable);
            //config.MessageTypes.Add("PositionUpdate");
            //config.MessageTypes.Add("SetClientPosition");
            NetworkingManager.singleton.StartServer(config);
        }

Could it still be because of Unity 5.6?
