MLAPI | game networking framework built for the Unity Engine | Networking library

I have MLAPI (https://docs-multiplayer.unity3d.com/docs/migration/install/index.html) installed with Tanks multiplayer (https://assetstore.unity.com/packages/templates/tutorials/tanks-multiplayer-mlapi-photon-mirror-69172#description), and when I import the tanks multiplayer code for MLAPI, I get the error: "error CS0246: The type or namespace name 'MLAPI' could not be found (are you missing a using directive or an assembly reference?)", even though it is installed, and I don't know what to do

I am trying to set up a networked event system in my Unity Project that allows triggering events on other clients. The event also is supposed to pass an EventArgs-type specific to that event.

However, apparently System.EventArgs is not Serializable and thus can not be directly sent over the MLAPI Network. Therefore I convert the class to a string with Unity's JsonUtility class and instead send that string. Additionally, I send another string which is the specific eventArgsType.ToString().

On client side, I am then converting the eventArgsType to a Type with GetType, and would then like to Deserialize the data-string into the correct eventArgs class. Which I currently do by nasty if-else case comparing to the possible eventArgs-Subtypes and then Deserialize as that. That works, but is extremely ugly and will get out of hand the more subtypes I have. But I am not quite sure of how to do that and would appreciate any tips.

What I currently have:

I am trying to destroy specific object on mouse1 click. I am using Unity MLAPI 0.1.0. When I spawn object (SpawnPuzzlePieceServerRpc), I save it's network id into a NetworkVariable. Object then follows mouse cursor (MakeActivePuzzlePieceFollowMouseServerRpc). After that, if I press mouse 1 button, I want that spawned object to be destroyed. Method (DeleteActivePuzzlePieceServerRpc) destroys object both on host and client, however, method continues to be called for some reason, and throws KeyNotFoundException: The given key was not present in the dictionary. NetworkVariable (activePuzzlePieceNetId) seems to be updated to 0 (because of the error throwned constantly), so the method shouldn't be called again because of the condition in Update(). It feels like NetworkVariable is not syncing correctly here. What could be the problem and what am I doing wrong?

Thanks in advance,

For my PlayerController script, I changed inheriting from MonoBehaviour to NetworkBehaviour

I was following the tutorial about 'Mlapi' in Unity. In the tutorial, I have a question when I studying about RPCs.

So the question I have is

1. When I make a method with the ServerRpc attribute how does the 'Mlapi' handle that method? According to 'Mlapi' documentation, All I have to do to call the ServerRpc function is just making a direct function call with parameters. But what happens when I call the method marked by ServerRpc? What I did was just calling the method marked by the ServerRpc attribute. But how the 'Mlapi' get method marked by the ServerRpc attribute or other Rpc attribute I wrote? And how does the 'Mlapi' call the method from the client and execute it on another machine?

I'm having a bit of an issue with a shell script, replacing url in a json file with sed, with an url stored on a variable. The code is this:

I'm using Unity 2020.1.3f and Input System 1.0.2 to create a simple racing multiplayer game with MLAPI 0.1.0 but whenever i start an instance of the game after building it and unfocus the window it still detecting my gamepad input (with keyboard does not happen), but when I play the game in Unity's game view and unfocus the editor it does not detect the input anymore. What can i do to only detect my gamepad input when the window is focused?

My Unity project is using MLAPI framework(UNet Transport). I have a server and 3 clients. Server needs to send RPC message to all clients every frame. The data flow is about 2KB/frame for each client. My project is running at 60FPS. The delivery and sequence of messages are not necessary.

However, server will pop up some warnings like "no free events for message" when running and then all connected clients disconnect automatically. Maybe the problem is broadcast frequency is too high and the message is too big. But I really need these.

Is there any suggestion about NetworkConfig settings? Any suggestion is appreciated.

Thanks a lot!

update: My project is working with a motion capture system and only the server can receive the motion data. So Server needs to broadcast it to other clients.That's why I need to do it every frame.
