Splitting is helpful for workflow reasons (all loaded identical for all clients), but splitting to support clients in different rooms only makes sense if the game doesn’t fit into a reasonable amount of memory.

[sharp axle]

Typically, open world games are not networked, so you are kind of in uncharted territory. You'll have to keep in mind that the host/server needs to keep all scenes in memory

[austere yacht]

it’s basically MMO tech

not achievable for most organizations

[sharp axle]

Its doable but its one of things that's like way harder than you would initially think

[livid nexus]

Uncharted how? Stardew is an example of exactly what I am trying to do in terms of how the multiplayer works if you are familiar with it. The map is divided up into smaller chunks where you just get hit with a loading screen once you hit the boundary of your current chunk

[livid nexus]

In terms of not splitting, how are things handled to make it less intensive on the system? for example, not rendering certain areas of the map if you’re not in it?

[lucid stag]

How do I make rbs able to rollback?

My networking code is frame based, and basically teleports objects back if it needs to resimulate, except rigidbodies get a stroke whenever you try to do that (and also rolling back velocity/angularVelocity litterally kills it)

[vivid pagoda]

Here's a general approach you can take Record State Before each frame update or simulation step, record the state of the rigidbodies including their position, rotation, velocity, and angular velocity.

[vivid pagoda]

or Smooth Transition to avoid strokes or sudden jumps in the simulation when rolling back, consider implementing some form of interpolation or smoothing between the current state and the rolled-back state. This can help maintain continuity in the simulation.

[uncut wren]

If I call Animator.Play() when using the NetworkAnimator, woulld it update the animator on other clients? There's no mention of using the Play function on the docs for it, as far as I can see

in fact, the docs only has the world "Play" in it once, and that's in the ribbon - referring to Multiplayer Play Mode

[sharp axle]

The only things that sync are the animation state and the parameters. If you want to call Play() you'll need to use a RPC

[uncut wren]

alrighty, thanks :)

[austere yacht]

Just like you would on singleplayer. In multiplayer you’re primarily concerned with not sending network updates to objects a player can’t see. To do that you just compare distance or other semantics like occlusion/zone/activity. In some frameworks (like mirror) such mechanics exist as builtin components and typically work out of the box for abstract (non-rpc) updates like network variables or transforms. For rpc‘s and low-Level messages you naturally have to diy.

one approach could be to divide your scenes into chunks (box volumes) and only update clients with what’s happened in their nearby chunks. Then you don’t have to constantly compare all objects‘ proximity

[carmine walrus]

I'm having some trouble understanding when to make a server do an action, as opposed to a client or owner, and sync that action across all players

say a client is trying to touch a flag to collect it using OnTriggerEnter, and that action then enables some hidden meshes in the player's object to indicate that player is holding the flag. what kind of variables would I need to sync in order to achieve this?

here's what I have right now:

when a flag is touched:

    NetworkVariable<bool> stolen = new NetworkVariable<bool>();
    PlayerStats playerCarrying;
    (...)

    void OnTriggerEnter(Collider other)
    {
        PlayerStats player = other.GetComponent<PlayerStats>();
        if (player == null) return;
        
        if (!string.Equals(player.tag, tag))
        {
            if (player.hasFlag || stolen.Value) return;
            player.hasFlag = true;
            flagMesh.enabled = false;
            stolen.Value = true;
            playerCarrying = player;
        }
        else
        {
            if (!player.hasFlag) return;
            player.hasFlag = false;
            GameManager.instance.AddTeamPoints(team, 1);
        }
    }

player's stats:

NetworkVariable<bool> _hasFlag = new NetworkVariable<bool>
    (false, NetworkVariableReadPermission.Everyone, NetworkVariableWritePermission.Owner);

 (...)

public bool hasFlag
    {
        get => _hasFlag.Value;
        set
        {
            if (_hasFlag.Value != value)
            {
                FlagUpdate();
            }
            _hasFlag.Value = value;
        }
    }

    private void FlagUpdate()
    {
        if(flagCarryObject != null) flagCarryObject.SetActive(!hasFlag);
        if(flagCarryEffects != null) flagCarryEffects.SetActive(!hasFlag);
    }

apologies for bumping off other users. there are some unanswered questions above this wall of text from the others.

[cerulean snow]

I dont know if i am in the right server, but here is my question:

What whould be the best networking solution to use for a mmo as an indie game dev?

I am familiar with Fishnetworking and Photon, but i don't know if they are what i need for 300+ players.

And i know that Netcode for game objects isn't suitable for mmo's, but n don't know anything about netcode for entities.

What whould you suggest?

[uncut wren]

You'd be better off contacting network solution providers directly with your plans

I domt think there'd be any plug and play or more simple solutions like NGO just readily available

And most net solutions would likely cap you WAY before you reach that 300+ without having prior authorisation anyway

[sharp axle]

MMOs all require custom networking solutions. So you would go with whatever your server team is most familiar with.

[warped pilot]

Hello is it possible to join a lobby with lobbyname and password ?

[urban berry]

Hello, I have a dedicated server running at all times using NGO, lobbies, and a relay server to allow WebGL. It seems like after some period of time the relay server expires and players can no longer join the server.

What is the expiration period for a Relay and how do I keep it alive for extended periods of time?

[sharp axle]

You can password protect a lobby but you still need either the lobby join code or lobby id to join.

[warped pilot]

ok thanks

[mental citrus]

Hello, ive been trying to make it so when you click on the hitbox of a ship you can move it around with your mouse, this works flawlessly on the host as the position is being synchronized on the client as well, problem is when the client tries to click and move the ship, as the bool does not update, the log does not get sent and obviosly the ship doesnt move for both client and host

using Unity.Netcode;

public class ShipManagerScript : NetworkBehaviour
{
    public GameObject myShip;
    public GameObject myHitbox;
    public bool isShipFollowingMouse = false;

    // Update is called once per frame
    void Update()
    {
        if (Input.GetMouseButtonDown(0))
        {
            MoveShipServerRpc();
        }

        if (isShipFollowingMouse)
        {
            FollowMouseServerRpc();
        }
    }

    [ServerRpc(RequireOwnership = false)]
    public void MoveShipServerRpc()
    {
        Vector3 mousePosition = Camera.main.ScreenToWorldPoint(Input.mousePosition);
        mousePosition.z = 0;

        Collider2D hitboxCollider = myHitbox.GetComponent<Collider2D>();
        if (hitboxCollider.bounds.Contains(mousePosition))
        {
            isShipFollowingMouse = !isShipFollowingMouse;

            // Print a debug log
            Debug.Log("Ship clicked. isShipFollowingMouse: " + isShipFollowingMouse);
        }
    }

    [ServerRpc(RequireOwnership = false)]
    public void FollowMouseServerRpc()
    {
        Vector3 mousePosition = Camera.main.ScreenToWorldPoint(Input.mousePosition);
        mousePosition.z = 0;

        myShip.transform.position = new Vector3(mousePosition.x, mousePosition.y, myShip.transform.position.z);

What does this do on the Network Manager?

Does it just mean whenever the server changes scenes, everyone does?

[severe ruin]

Problems with how to serialize ulong[] arrays (not trying to use lists)
This documentation says
Arrays of C# primitive types, like int[], and Unity primitive types, such as Vector3, are serialized by built-in serialization code.
https://docs-multiplayer.unity3d.com/netcode/current/advanced-topics/serialization/arrays/
So one would think the following is possible

public NetworkVariable<ulong[]> Ids= new NetworkVariable<ulong[]>(new ulong[0], NetworkVariableReadPermission.Everyone, NetworkVariableWritePermission.Server);```
But (for me) this prints this error (which contradicts documentation stating  "Arrays of C# primitive types" should be handled) 
```Serialization has not been generated for type System.UInt64[]...````

[sharp axle]

Disabling it means the newtork manager will not sync the scene or its network objects with the clients and you will need to manage them yourself
https://docs-multiplayer.unity3d.com/netcode/current/basics/scenemanagement/custom-management/

[sharp axle]

That will work with RPCs but not NetworkVariables
You will need to use NativeArrays there
https://docs-multiplayer.unity3d.com/netcode/current/advanced-topics/serialization/arrays/#native-containers

[livid nexus]

Okay, let's say I want to do a small scale open world game, with no dedicated server (a player is hosting) and ideally, the different clients can go wherever they please in the world.

What is the conceptual idea for doing this? ie, originally, I was thinking that the world is divided up into different scenes, and the players can load into different scenes. However, Netcode for GameObjects does not really support this type of behavior.

What topics should I be looking into?

[sharp axle]

Really depends on how large the world is. You'll need to save some kind Area of Interest or visibility system so the host isn't just simulating every NPC in the entire world when no one is around. But the world still needs to progress even when no one is present.

[hot plinth]

Hey, this part of the tutorial is wrong I think? https://docs.unity3d.com/Packages/com.unity.netcode@1.2/manual/rpcs.html?q=PostUpdateCommands

[WorldSystemFilter(WorldSystemFilterFlags.ServerSimulation)]
public class ServerRpcReceiveSystem : SystemBase
{
    protected override void OnUpdate()
    {
        Entities.ForEach((Entity entity, ref OurRpcCommand cmd, ref ReceiveRpcCommandRequest req) =>
        {
            PostUpdateCommands.DestroyEntity(entity);
            Debug.Log("We received a command!");
        }).Run();
    }
}

It's inheriting from SystemBase without marking the class as partial, and PostUpdateCommands is not mentioned anywhere else in the docs

i'm about to watch an hour long video about unity input systems and making controls for pc/xbox/playstation controllers and so on. I read on unity's site and other places that netcode requires things to be different.

can someone elaborate what that means for controls? is it as simple as me adding netcode to the top of any input.c scripts?

i don't wanna get halfway through or fully through an hour long process only to have to undo it for multiplayer because netcode wanted it a specific way

[sharp axle]

You just have to make use that the input is only getting applied to the local player

[summer otter]

Does anyone know how I could get NavMeshAgent root motion working with NGO using server authoritative movement?

[sharp axle]

Ot should just work with a network Transform. You probably need to disable the navmesh agent on the client though.

[summer otter]

Yes you are right. Basicly without root motion, the NavMesh is working. But with root motion I struggle with the OnAnimatorMove method calls, which could not called by the ServerScript (Animator only is set on ClientObject). On the client side I've no access to the NavMeshAgent, which has to be sync with the animation in OnAnimatorMove. Is it a bad decision to separate the scripts for server and client? Or do you have an other idea to solve this problem?

[sharp axle]

I don't personally like to separate scripts into client and server but its not a bad idea. That's how the Boss Room sample does and they use Navmesh agents
https://docs-multiplayer.unity3d.com/netcode/current/learn/bossroom/bossroom-architecture/#navigation-system

[summer otter]

@sharp axle Boss-Room is where I Gott the separation Idea from. But they use Ridged-Bodies with NavMesh and not root motion

[astral spear]

Idk which channel fits for this problem 2024-03-12T15:06:25.5532] @firebase/database: FIREBASE WARNING: Provided authentication credentials for the app named "[DEFAULT]" are invalid. This usually indicates your app was n initialized correctly. Make sure the "credential" property provided to initializeApp() is authorized to access the specified "databaseURI." and is from the correct project. But this the closest channel

How do i fix this?

[noble veldt]

Right, if you are using server authoritative and moving them on the server only, then having animations that move them will be a problem and usually the client's are where you run animations at and not even on the server - although with a shooter, and collider checks, you probably would want that but it's more difficult since you put more stress on the server. If you still want that then probably somehow allow the transform movement just on the server and then NOT on the clients and probably disable the NavMeshAgent on the clients anyways

So one question might be, do you actually care if the animation is run on the server for arm/leg collider movement and checks? If you aren't doing a shooter then maybe not and you can take that load off the server and just run the animation on the clients.. but then you are saying you want root movement, which is a problem

So basically maybe you just want the script on both server and client, but then on the client ignore the transform movement so that it doesn't try/doesn't jitter, or research how to properly sync it as a client predicted movement somehow.. and then you are saying you don't have access to the NavMeshAgent (and I even suggested disabling it on clients above) so I think you do understand the problem

So maybe the question is: How do you client predict/sync movement where the NavMeshAgent is used on the server but it doesnt exist or is disabled on the client, or can you have NavMeshAgent active on both client and server and use client prediction for moving them both?

[steep sparrow]

Hey. I'm building an app for mobile and I want to store data in a database however I don't want to synchronize all the data on all databases because the app should be available in each country and then I'd need for each region a database. Is there a tool which provides Multi-Region-Cloud-Service so that I don't have to design the regional database synchronization by myself?

[summer otter]

Thanks @noble veldt for your hints. You are right, client prediction is something what I've already in my mind. So I should dig about this a little bit deeper. Actually I found only tutorials and hints for client prediction without using a NavMesh, so I've placed it to bottom of my to-dos, but maybe I should priorize this.

can someone give me the "for dummies" version of how to make a p2p lobby for friends to join thats safe. i don't want people to have to mess around with their firewall and whitelist folks just to test out multiplayer. i want to use the unity features, friends, lobby, and relay with netcode to make lobbies and friendlists for us to join

[sharp axle]

Lobby and Relay are what you need there

[tribal stream]

so there's no multiplayer from the unity dashboard?

ok thats good to know

i think i may be able to figure it out from there. its super annoying getting part way through a tutorial and needing another tutorial to fix or teach what one inconvieniently left out.

vent over- back to it

[noble veldt]

depending on what you are using to access the database, all you need to do is use the same schema and you change the database name like append a country code.. so your code doesn't change at all just the name you use to connect to the database.. so database name "MyGame-NA" and "MyGame-ASIA" or whatever you want for the regions, or use the region names that Unity has appended onto the database name, however u want to name them with regions

Hello, is it possible if someone presses ready in the lobby that the host will see when everyone is ready and he can start the game?

[rapid crater]

does anyone have experience with the asset ObjectNet who could suggest why it may be easier than Net Objects?

[sharp axle]

Sure, just create a "Ready" lobby Player Data variable. The host can see these and count who is ready

[drowsy spindle]

you have to use sync variables for camera logic right? im trying to migrate some stuff ive been working on from monobehaviors to network behaviors and really really unsure about it. havent been able to get anything working.. so do [SyncVar] require a certain package or something?

[sharp axle]

If you are using Netcode for GameObjects then it does not use sync vars. I think that's Mirror. But also the camera should not be networked in any case. Unless for some crazy reason you have remote players controlling each other's camera

HI everyone, I have no idea where to post this. My tutor buddy is currently asleep I think, or is getting there. So I don't want to keep bugging him. I need to know how to do a project between two computers. I own both computers, too poor to afford the whole seats thing with unity.

What is the best way to deal with a remote project?

1. GitHub Desktop was suggested, but when I go to install it GH wants me to put my project on the github wensite. Am I doing it wrong? Can't I just have my two computers communicate with each other directly?

2. Unity seems to have conflicting information on remote projects. One site says I have to pay, another site says I can just connect my two computers to each other via my network at home. Which is which?

3. Should I just do some microsoft file sharing with a file that's just shared between both computers?

[drowsy spindle]

@hoary shell maybe you're looking for something like promethean ai? although i think the microsoft file sharing is the most professional way to do it.

[hoary shell]

I just need to find the easiest and most reliable since i'm the only one who is using the file

[drowsy spindle]

i think cloud is currently free for right now through unity

this is probably not networking question tho.. i'd ask in unity talk

[hoary shell]

well I apparently can't share regardless of what I attempt because microsoft keeps demanding passwords even though I turned them off

[sharp axle]

You really should be using version control in any case. GitHub is a good choice but Unity Version Control is free for up to 3 people I think. You have to set up a dev ops accounts but it won't charge you unless you go beyond the free limits

I have already built the project, so no, I don't get to see them – however, while I was following that part of the tutorial, it was working on local multiplayer.

        };
    }

        var dataCopy = _networkTextData.Value.ToString();

        dataCopy += $"{(IsHost ? "Host " : "Client ")} ({OwnerClientId}): {msg}\n";

        if (dataCopy.Length > 4096)
        {
            dataCopy = dataCopy[(dataCopy.IndexOf('\n') + 1)..];
        }

        _networkTextData.Value = dataCopy;
    }

    public void Log(in string msg)
    {
        SendLogServerRpc(new ForceNetworkSerializeByMemcpy<FixedString4096Bytes>(msg));
    }

    {
        RecvLogClientRpc(msg, new ClientRpcParams
        {

            {
                TargetClientIds = NetworkManager.Singleton.ConnectedClientsList.Select(c => c.ClientId).ToList()

    )
    {
        UpdateText(msg.Value.ToString());
    }
}

I also tried this just using a NetworkVariable like I was doing at the very beginning:

using TMPro;
using Unity.Collections;
using UnityEngine;
using Unity.Netcode;

public class DebugLogText : NetworkBehaviour
{
    private TextMeshProUGUI _debugLogText;

    private NetworkVariable<ForceNetworkSerializeByMemcpy<FixedString128Bytes>> _networkLog =
        new(
            writePerm: NetworkVariableWritePermission.Owner,
            readPerm: NetworkVariableReadPermission.Everyone,
            value: new FixedString128Bytes("Uninitialised from network")
        );

    private void Awake()
    {
        _debugLogText = GetComponent<TextMeshProUGUI>();
        _debugLogText.text = "Uninitialised\n";
    }

    private void OnEnable()
    {
        _networkLog.OnValueChanged +=
            (prev, curr) => _debugLogText.text += curr.Value.ToString();
    }

    public void Log(in string msg)
    {
        FixedString128Bytes log = $"{(IsHost ? "Host " : "Client ")} ({OwnerClientId}): {msg}\n";

        Debug.Log(log);
        _networkLog.Value = log;
    }
}

Here, a lot of additional logs are printed by the host and its client. The other client logs out some data but it disappears in a flash; the host then shows that this client got disconnected.

[weak plinth]

NOCONNECT

Checking logcat, I find that the host is always created successfully, but the client for whatever reason cannot be created and errors out in the logs.

I've even added my UI class to the list of network prefabs

anyone got any reccomendations for a tutorial to learn unity netcode?

[tribal stream]

how do i get that menu to show up? i added and connected relay and made a test script with a debug log but this menu refuses to show up

https://www.youtube.com/watch?v=msPNJ2cxWfw&t=219s its from this tutorial and ngl its making me mad, a few parts of this tutorial are already deprecated after barely a year

[weak plinth]

Looking for help to connect stuff up!

[tribal stream]

same bro, this is confusing

i can set up a cloud vm but not stupid multiplayer. how is this harder😭

i just wanna set up multiplayer with lobby and relay so me and my testers dont have to mess with firewall permissions. can someone give me the dummy proof walk through on doing that?

[weak plinth]

I'm kinda trying to solve the same problem, I think

However in my case I'm connecting two 'Android' devices together

[tribal stream]

oof

tbh i'd love to get to the point where i could test multiplayer on other devices like ios and android but i just simply cannot get it all connected correctly in the first place

i have all the packages, i've got netcode, but i cannot seem to get relay to work to even set up lobbys for any platform

the debug menu refuses to load so i have no idea if i connected everything correctly

in my case it enters play mode and freezes, it doesnt error out or break, but it wont do anything despite setting up a player controller. its just stuck...

[weak plinth]

I suggest writing your own logging logic. Are you building to Windows?

[tribal stream]

I am

i'd like to add mac since some of my debuggers use macs

[weak plinth]

It's easier imo since you could just preview it through the editor. You will have access to the logs.

Unless you need that package because you want them to debug built executables?

You could use this script for that:

using System.Linq;
using TMPro;
using Unity.Netcode;
using UnityEngine;

public class CustomLogHandler : ILogHandler
{
    private readonly ILogHandler _defaultLogHandler = Debug.unityLogger.logHandler;
    private string _textLocalCopy;

    private TextMeshProUGUI ui { get; }

    public CustomLogHandler(in TextMeshProUGUI ui)
    {
        this.ui = ui;
    }

    public void LogFormat(LogType logType, UnityEngine.Object context, string format, params object[] args)
    {
        var logFmt =
            $"{(NetworkManager.Singleton.IsHost ? "Host " : "Client ")} ({NetworkManager.Singleton.LocalClientId}): {format}\n";

        var uiLog = string.Format(logFmt, args);
        if (uiLog.Length > 256)
        {
            uiLog = uiLog[..253] + "...";
        }

        if
        (
            uiLog.Contains("error") || uiLog.Contains("Error") || uiLog.Contains("ERROR") ||
            uiLog.Contains("exception") || uiLog.Contains("Exception") || uiLog.Contains("EXCEPTION")
        )
        {
            uiLog = "<color=red>" + uiLog + "</color>";
        }
        else if (uiLog.Contains("warning") || uiLog.Contains("Warning") || uiLog.Contains("WARNING"))
        {
            uiLog = "<color=yellow>" + uiLog + "</color>";
        }

        _textLocalCopy += uiLog;

        if (_textLocalCopy.Count(x => x == '\n') > 20)
        {
            _textLocalCopy = _textLocalCopy[(_textLocalCopy.IndexOf('\n') + 1)..];
        }

        ui.text = _textLocalCopy;

        // Also write the log to the default console
        _defaultLogHandler.LogFormat(logType, context, logFmt, args);
    }

    public void LogException(System.Exception exception, UnityEngine.Object context)
    {
        var uiLog = exception.ToString();
        if (uiLog.Length > 256)
        {
            uiLog = uiLog[..253] + "...";
        }
        uiLog = "<color=red>" + uiLog + "</color>";
        
        _textLocalCopy +=
            $"{(NetworkManager.Singleton.IsHost ? "Host " : "Client ")} ({NetworkManager.Singleton.LocalClientId}): {uiLog}\n";
        if (_textLocalCopy.Count(x => x == '\n') > 20)
        {
            _textLocalCopy = _textLocalCopy[(_textLocalCopy.IndexOf('\n') + 1)..];
        }
        
        ui.text = _textLocalCopy;
        
        // Also log the exception to the default console
        _defaultLogHandler.LogException(exception, context);
    }
}

[tribal stream]

thing is I'm not sure if i will need them too. i have different debuggers, some for testing multiplayer, others for single player and so on. maybe i shouldn't specify down like that and just find people who can test and debug everything

[weak plinth]

Perhaps, yeah

[tribal stream]

is this your custom script or does it come from unity?

[weak plinth]

Custom, technically GPT inspired

works tho

[tribal stream]

interesting... i may borrow that. but I'm still gonna try other ways first before i resort to using someone elses stuff

if i end up using it I'll credit you in the games end credits

that's okay, just providing a sure shot solution to only the logging sitch

thank you

[placid onyx]

did you make sure the RPC gets called after OnNetworkSpawn ran?

[keen briar]

can someone help me with multiplayer on multiplayer HLAPI movement? (i already have networking setup and players can join and everything works but player movement is client sided)

[mental citrus]

Did you add a client network transform?

[keen briar]

what's that

[keen briar]

what is a client network transform

i';m cofnused already

[sharp axle]

HLAPI got deprecated many many years ago. Are you using Netcode for GameObjects?

[keen briar]

no

i'm using HLAPI

in unity 2021

netcode is too hard

[warped pilot]

Hello I have LobbyEvents:

    callbacks.KickedFromLobby += OnKickedFromLobby;

But It will trigger too when I LeaveLobby .. Is there a way to fix this ?

[rough folio]

Set a flag when leaving the lobby intentionally, and add an if in OnKickedFromLobby that checks for it?

[warped pilot]

What do you mean exactly?

I got it .. Sorry im dumb

Ok it doesnt work I have tried it with when I Leave Lobby: m_GetKickedFromLobby = false;
When I get kicked: m_GetKickedFromLobby = true;

And on the event:

 {
     if (m_GetKickedFromLobby)
     {
         m_UiLobbies.SetupLobbieKick();
         PopupManager.MyInstance.AddToRedQueque(m_UiLobbies.LobbyKickText.GetLocalizedString());
     }
 }```

[rough folio]

With this setup, m_GetKickedFromLobby should always be true, except specifically when you press the button to leave the lobby. Then it turns to false, lobby is left, and after the event OnLobbyKicked is fired and is over, then it is set back to true. I think that's the best way to do that?

[warped pilot]

yea i did it

now it works

i was thinking about it

[rough folio]

nice

[warped pilot]

yes is working thanks a lot

is it possible to ban him from lobby ? because when I kick him he can rejoin again

i think with data or ?

and safe playerid to ban

[rough folio]

that's very dependent on what you're actually using for networking, but probably there is a way

[sharp axle]

Yea. you can disable their Player ID in the dashboard. And there is also an entire Moderation SDK.
https://docs.unity.com/ugs/en-us/manual/moderation/manual/overview

[heady summit]

did you make sure the RPC gets called

[tender saffron]

anyone here familiar with Photon Quantum?

I'm trying to access an enum from a .qtn file and I'm not sure how to reference it

[drifting plaza]

Anyone what what a reasonable maximum ping to engineer my game around should be with dedicated hosting?

[sharp axle]

It really depends on the type of game. Fighting games are way more sensitive than card games. Mobile games can do weird things when traveling between cell towers.
The network simulator can test these scenarios

[high sierra]

Hi guys , I've just started using unity and was wondering what is the best way to share the project to some of my friends

[stable dust]

im attempting to make a multiplayer game i have a player setup but when i build the hosts camera doesnt move do i have to use cinemachine instead?

i can send a video of the issue if needed

[sharp axle]

Like for development? Or just play testing?

[sharp axle]

No you don't have to use cinemachine but you can if you want. It works pretty well with networking

[placid onyx]

you probably have the code that controls the camera not isolated to the controlling player
ideally put the camera in the player prefab and make sure it only gets enabled for the controlling (owner) player

[fickle ridge]

Hello i have a problem with Photon not instantiating is there a general solution for that?

[stable dust]

for some reason the hosts camera is placed in some random spot when a client joins?

i went through all scripts and the setup of the prefab

[sharp axle]

You need to disable the camera on the remote player

[stable dust]

how would i go about doing that

would i make it happen when i click the client button or?

[sharp axle]

In the player's OnNetworkSpawn() you check if(IsLocalPlayer) then disable the camera

[stable dust]

thank you

[tribal stream]

https://youtu.be/bOf6CjpuSFs?si=u9bzIpl2OSlxbcW2 i'm still super confused and this tutorial was not any more helpfull than any of the others he has. this one depends on steps taken 5 hours earlier. I just want to set up lobbies, friends and relay.

and preferably without having to buy 40 dollar addons that he uses

i installed each of their packages and have them enabled in the dashboard but I don't know what to do from there

[sharp axle]

Those are 3 very different services. But the basics is to Create a Lobby first then Create a Relay. Add the Relay Join Code to the Lobby Data. Anybody joining the Lobby can see the Relay Code and join the Relay.

You can add Friends by Player Id or Username. You don't need to be connected to the game to do that

[tribal stream]

problem is, i don't know how to create a relay or lobby. i have it installed but i don't see it on any drop downs

i don't know how he opened it. for him it looks like it just opens. that doesnt happen for me

i just want to get into the actual game developement but i can't until multiplayer is working, and i can test that it works

[tribal stream]

quite litterally, the guy says at this time stamp "lets check and see if this works" but he tests it on a 40 dollar asset i don't have and I'm NOT going to pay for. so i have no idea if what i did even worked

[torn lance]

First time working with the netcode for gameobjects, just making sure I'm not walking down the wrong path. I want to maintain the struct FightState in a NetworkVariable<FightState>, and to do that I need to serialize/deserialize an unknown size array. Is this achieving what I think it is?

public struct FightState : INetworkSerializable
{
    public EntityState[] playerStates;

    public void NetworkSerialize<T>(BufferSerializer<T> serializer) where T : IReaderWriter
    {
        // I assume this uses the ReadValueSafe and WriteValueSafe functions I define below?
        serializer.SerializeValue(ref playerStates);
    }
}

public static partial class SerializationExtentions
{
    public static void ReadValueSafe<T>(this FastBufferReader reader, out T[] unmanagedTypeArray) where T : INetworkSerializable, new()
    {
        reader.ReadValueSafe(out int length);

        unmanagedTypeArray = new T[length];

        for (int i = 0; i < length; i++)
        {
            reader.ReadValueSafe(out T val);
            unmanagedTypeArray[i] = val;
        }
    }

    public static void WriteValueSafe<T>(this FastBufferWriter writer, in T[] unmanagedTypeArray) where T : INetworkSerializable, new()
    {
        writer.WriteValueSafe(unmanagedTypeArray.Length);

        for (int i = 0; i < unmanagedTypeArray.Length; i++)
        {
            writer.WriteValueSafe(unmanagedTypeArray[i]);
        }
    }
}


public struct EntityState : INetworkSerializable
{
    public int hitpoints;
    public int mana;
    public int stamina;

    public void NetworkSerialize<T>(BufferSerializer<T> serializer) where T : IReaderWriter
    {
        serializer.SerializeValue(ref hitpoints);
        serializer.SerializeValue(ref mana);
        serializer.SerializeValue(ref stamina);
    }
}

[sharp axle]

problem is, i don't know how to create a relay or lobby

[sharp axle]

It might be easier to use Native Arrays. But also your array length shouldn't be unknown. Just pick a reasonable maximum like 120 if you're keeping the last 2 seconds of updates.

[torn lance]

(not really an important factor but it's actually a turn based game so the states are saved after each round its not a rollback thing)

pain in every direction, it seems

unknown length since the battles will have varying amounts of allies and enemies

does [MarshalAs(UnmanagedType.ByValArray, SizeConst = 128)] work in order to trick it into seeing the struct as unmanaged and avoid the headache?

[sharp axle]

No clue. But I doubt it. If it were that easy, then it'd be done by default

[torn lance]

Actually it does look like there's already an implementation for this I had just missed the correct docs page somehow

/// <summary>
/// Write a NetworkSerializable array
///
/// "Safe" version - automatically performs bounds checking. Less efficient than bounds checking
/// for multiple writes at once by calling TryBeginWrite.
/// </summary>
/// <param name="value">The values to write</param>
/// <param name="unused">An unused parameter used for enabling overload resolution based on generic constraints</param>
/// <typeparam name="T">The type being serialized</typeparam>
[MethodImpl(MethodImplOptions.AggressiveInlining)]
public void WriteValueSafe<T>(T[] value, ForNetworkSerializable unused = default) where T : INetworkSerializable => WriteNetworkSerializable(value);

thanks for the help though, I always forget about NativeArray

Hey what is a good practice to make a ready check for Unity Lobby system ?

[sharp axle]

Use Lobby Player Data to save a bool and then use Lobby Events to subscribe to changes in the lobby data

[rancid fjord]

Does network for GameObject support wifi direct? or any way to host & play without a having a wifi network currently accesible (such as creating a hotspot or using wifi direct)?

[keen briar]

is multiplayer HLAPI a good API for multiplayer?

[sharp axle]

Unet HLAPI is no longer supported. Netcode for Gameobjects is the Unity supported networking framework. Here are the docs if you need to migrate from an old project
https://docs-multiplayer.unity3d.com/netcode/current/installation/upgrade_from_UNet/

[keen briar]

multiplayer HLAPI is easier to use i think

[sharp axle]

It has also been completely removed from the latest versions of Unity

[torn lance]

The editor seems to be dying when it's serializing a NetworkVariable of an enum (even though it's allegedly supported). Is this some known bug or what?

it does look like the Type[] argument is getting passed just a Type which maybe is causing problems? the docs say MethodInfo.MakeGenericMethod(Type[]) with zero overrides https://learn.microsoft.com/en-us/dotnet/api/system.reflection.methodinfo.makegenericmethod?view=net-8.0

            var type = m_NetworkVariableFields[m_NetworkVariableNames[index]].GetValue(target).GetType();
            var genericType = type.GetGenericArguments()[0];

            EditorGUILayout.BeginHorizontal();
            if (genericType.IsValueType)
            {
                var method = typeof(NetworkBehaviourEditor).GetMethod("RenderNetworkContainerValueType", BindingFlags.Public | BindingFlags.Instance | BindingFlags.FlattenHierarchy | BindingFlags.NonPublic);
                var genericMethod = method.MakeGenericMethod(genericType); // << this is causing the error   "ArgumentException: Invalid generic arguments      Parameter name: typeArguments"
                genericMethod.Invoke(this, new[] { (object)index });
            }

[high sierra]

development yes

[sharp axle]

You would a version control system. Like Git or Unity Version Control or Perforce. Add your friends to the team and everyone can get synced up

[fickle ridge]

Hello i have a question about synchronising player movement in multiplayer with Photon. When i build my game, and i run the game once, there's no problem. But when i log a second time with another window of the game, when im in one window, i control the second character, and when im in the other window, i control the first character
is there a way to switch that?

[warped pilot]

Hey how can I update LobbyData ?

[fluid walrus]

usually you'd use FastBufferReader/Writer for that kind of thing, or is there some feature those are missing that you need?

[frank dragon]

Hey! Bit of a random question but is there a way to see if the user has a specific website open (eg running a check to see if they current have Facebook open in the browser)

[fluid walrus]

if the types in the list are also INetworkSerializable you should be able to do serializer.SerializeValue on them in your NetworkSerialize method, does that not work for you?

[solar geode]

Hi, someone can help please?, Im using Photon2 and the RPC Calls, I have an array of Sprites, which is selected randomly and the position of the array is saved in a variable, but when I want to make the Others RPC call, the value that I save in the variable to show the same Sprites to others players, doesn't saves the value and always returns position 0, there is the code

For those familiar with fishnet, what is the difference between a TargetRpc and an ObserverRpc?

[icy flint]

Hey does anyone have a good guide on how to setup a Player mouse script to work with NGO?
I can only find movement scripts but nothing regarding the actual player rotation

[sharp axle]

Client network transform will sync rotation and positions

[icy flint]

but I need it to be server authoritive

[sharp axle]

You will need to send screen to world point in a rpc. But the lag is going to be unbearable

[icy flint]

well what's the best solution? client authoritive is going to make this a cheating hell (even if its just a small school project)

[livid nexus]

Why does the mouse position need to be sent to the server?

[icy flint]

well when the player turns other people should be able to see the player turn

[livid nexus]

So your mouse position is used to turn the player? Is it a first person game or something of the sorts?

[icy flint]

yes

its going to be a small scale FPS

[livid nexus]

Because then all you need to worry about is synchronizing the players rotation to the Server and not the player input itself

ie you can have the movement be server authoritative and the rotation be client authoritative and just synchronize the transform information to the server

[icy flint]

well how would I do that? just a network transform and my normal mouse script?

[livid nexus]

I think so yeah

I’m using fishnet and not NGO so I’m not familiar with the explicit details on how you would do it, but conceptually it’s the same idea

[fickle ridge]

does anyone know why when i run 2 instances of my game, i can control the other player's movements? I work with photon btw

I just imported FUSION2 and got the error

Assets\Photon\Fusion\Runtime\FusionStats.cs(722,15): error CS0103: The name 'FindFirstObjectByType' does not exist in the current context

and should I use FUSION or FUSION2

[livid nexus]

Not familiar with photon but sounds like you haven’t done an ownership check on your movement controller

[fickle ridge]

How do i do that?

[livid nexus]

With NGO or fishnet you can do an isOwner check. It’ll return true if the owner of that game object is the one that’s running the script

Essentially in your update method (where you have your movement code), you can can first have if(!isOwner) {return;} before your actually movement code which will cause the rest not to run on the device unless you own that game object

Are you trying to start a host on each clone?

[weak plinth]

Hey, now that my replication code is working, the next step in my app is to use voice chat and some kind of transcription. My obvious choice is Vivox for audio, and while I wanted to use STT on it, this appears to be an early preview feature, and not even available for regular use.

I started investigating how to retrieve audio data from Vivox and found this: https://docs.unity.com/ugs/en-us/manual/vivox-unity/manual/Unity/developer-guide/audio-taps/access-audio-data

My understanding is that I should be able to save this data and upload it to another service such as Google or Microsoft Azure for speech-to-text (which is a requirement my supervisor set for me). How should I go about doing that from the float array provided in OnAudioFilterRead?

can some one help me with my player model

I'm developing a VR game using Unity's 3D Core and have imported a character model from Blender. However, the ears of the character are visible to the player, which I want to avoid. I aim to make the ears invisible to the local player while ensuring they remain visible to other players in a multiplayer setup. Can anyone offer guidance on achieving this?

The character model is made in Blender.
I'm seeking a solution that involves adjusting visibility specifically for the local player while preserving visibility for other players in a multiplayer environment.
VR headsets supported include Meta Quest 2, Meta Quest 3, Meta Quest Pro, and Valve Index.
Request for Assistance:
I'm looking for suggestions or methods within Unity's 3D Core to effectively manage the visibility of certain parts of a character model based on the player's perspective in a multiplayer VR environment, considering compatibility with Meta Quest 2, Meta Quest 3, Meta Quest Pro, and Valve Index.

I forgot old code using parrelsync that indeed was starting a host because of logic that i removed when switching, so yes. Thank you

The easiest way is to have a separate model for the local player and one for the remote players. You could also change the rendering players

so i made a post about this and it seems like other ppl got this problem too after upgrading to 1.8.1 (network object script not working)
i have no clue how to fix it :,(

[autumn gorge]

Hi, i'm working on adding the ennemis for the client, they are only visible by the host and when i try to make them spawn i have this error

here's the code for the spawner

[ocean tapir]

hello, im really new to networking and im just trying to get a 2 clients to move around with a dedicated sever. although im having trouble with the cameras. i have given each player a tag and im now trying to disable the opposite players camera. so i need something that runs only on the client and is different for each one. i tried a clientrpc but it doesn't seem to be working because it has no control over the objects.

[sharp axle]

Only the server can Spawn objects

[sharp axle]

In the players OnnetworkSpawn(), check for !IsLocalPlayer then disable the camera

[ocean tapir]

i changed my code to this void OnNetworkSpawn(){
if (!IsLocalPlayer){
Transform EnemeyCam;
if (transform.tag == "Player 1"){
EnemeyCam = GameObject.FindWithTag("Player 2").transform.GetChild(0);
EnemeyCam.gameObject.SetActive(false);
}
else{
EnemeyCam = GameObject.FindWithTag("Player 1").transform.GetChild(0);
EnemeyCam.gameObject.SetActive(false);
}
}
}

but it hasnt had a difference

[sharp axle]

You don't have to do anything with tags. When the other players spawn on each client the player object will check if it's the local player. If it's not then you can safely disable the camera on it

[ocean tapir]

ok i think i got it but i might be referencing the camera wrong

void OnNetworkSpawn(){
if (!IsLocalPlayer){
transform.GetChild(0).gameObject.SetActive(false);
}
}

[ocean tapir]

shit nvm i forgot to override the function thanks so much although i still don't really know what on network spawn and is local player do

[placid onyx]

Make sure you have only ONE of the players assigned to either server or host role. You'll at least get a transport error if two players try to serve/host since that port is already in use. Also check the IP and port you assigned, server IP should be either 0.0.0.0 or 127.0.0.1 and for port use any that's free (default: 7777). Sometimes, a port may not be properly closed, a reboot can also help to fix that.

[placid onyx]

restart Unity? In case you added the module while that editor was still open. Also check if that's the exact editor version your project uses. Finally: try reboot.

[placid onyx]

using GameObject.Find("") will get you into big trouble with networking specifically
assign references in Inspector or use GetComponent or any other means
I prefer to write a lot of smaller components specifically for networking, for instance I have a NetworkSpawnEnableComponents script that I put on my prefab, and drop in any component I want enabled if the object is either owned or not owned by the client so I need not code any of this
may be much to take in but here's my netcode package: https://github.com/CodeSmile-0000011110110111/de.codesmile.netcode
check Runtime/Components

[placid onyx]

also: my player prefab contains the camera (and virtual camera) so its part of the object, which makes it easy to toggle camera: if (IsOwner) => enable
I prefer to have the components disabled by default because that's the default case for a player, since there's only one owner but many non-owners

[autumn gorge]

how can i corrct this problem ?

[fluid walrus]

first of all it looks like there's no need for Spawner to be a NetworkBehaviour? it doesn't have any RPCs or network vars

[autumn gorge]

ah yes i see

so back to monoBehavior

do i have to add network object to the spawnpoit too ?

[fluid walrus]

no, it should only need your script, then you can do NetworkManager.Singleton.IsServer instead of IsServer

i think some of your errors right now are coming from when Spawner was destroyed at the end?

that should help with that at least

[autumn gorge]

ty, i'll try this

it still works for the host but client have not camera rendering even tough it worked before i added theses lines:

        var onlineMonster = monster.GetComponent<NetworkObject>();
        onlineMonster.Spawn(true);

error of the cloned project

and also the ai is completely broken, it follows me on the first second and then it goes everywhere even tough it worked properly when instantiate for client

[fluid walrus]

have you added your monster to the prefab list in the network manager config? that's what the top error is saying

[autumn gorge]

you mean this ?

[fluid walrus]

yeah, is that the same between host and client?

oh, wait it's complaining about soft sync, that's objects in the scene

is there any NetworkObject in the scene?

[autumn gorge]

on my clone it is

[autumn gorge]

yes, the spawner

[fluid walrus]

you can remove the NetworkObject from that

it's only going to run on the host anyway, it doesn't need to be synced itself

[autumn gorge]

oh okay

i try to start a game

damn still complaining

im trying to find the hash of the prefab

[fluid walrus]

there's still network objects in the scene it looks like

if they're not in the prefabs list it can't sync them

so either make them not NetworkObjects, or add them there!

[autumn gorge]

ty for your time, i'll find it haha

[autumn gorge]

it worked, ty so much

now i just have top deal with ai problem

[fluid walrus]

nice 🙂

[autumn gorge]

this time ai wont work properly

since everything is on netcode even tough on local it work properly

[autumn gorge]

the ai work properly my bad, its the prefab that slides on the surface

but i have no clue on how to fix it

[icy flint]

Hey,

I am working on a small FPS game with Unity NGO, Lobby and Relay.
I was wondering how I could add a second prefab for the second team, and how I would handle which Prefab the Player should use and where he should spawn

[weak plinth]

Has anyone used whisper.unity with Vivox before? https://github.com/Macoron/whisper.unity

[onyx dust]

hi
I have a camera in the character that’s attached to the character’s head. The animation causes character to start shaking. I decided to use the Virtual Camera (it follows the empty "zxc" object in the character’s head model) from Cinemachine.When I run the game alone, everything works fine.But when I enter the game with 2 clients,then the script CinemachineVirtualCamera disappears in VirtualCamera and creates a child element cm.

[sterile creek]

Runtime/Extensions/NetworkManagerExt.cs
using UnityEditor; wont build. idk how to mark it on github. Actually found it in a few locations now.
But cool package!

[astral spear]

I got this backend thingy runnin a server at localhost:3000 how do make my game connect to it?

Like they said i need to put up the right adress

Ion get it

[sharp axle]

Nothing using UnityEditor will build. As the name suggests it's editor only

[sharp axle]

You're gonna have to be more specific.

[sterile creek]

That’s what I said… it’s not my code

[fickle ridge]

Guys do you recommend fishnet or Photon for multiplayer?

And which is easier to implement?

[sterile creek]

They all feel pretty similar, there is also unity netcode for gameobjects. I would just pick one

[fickle ridge]

Yeah but i already used photon for my project and the result was unbeliavable in a bad way

like one player was controlling the other player and vice versa

[astral spear]

I need to put the right address of my game on this localhost:3000

Like connect the unity game in this localhost

[sterile creek]

Hahah we call that user error 😉. Networking is hard. A different library doesn’t make the concepts any easier

[sharp axle]

That depends on what kind of a server this is.

[astral spear]

Set it up using a nodejs and firebase

[sharp axle]

Netcode will not connect to nodejs
You can do a unity web request though

[astral spear]

Multiplayer kind?

[astral spear]

How so?

[sharp axle]

https://docs.unity3d.com/Manual/UnityWebRequest-SendingForm.html

[fickle ridge]

Guys anyone knows how to correctly use Git?

Im in dire need of a competent person

[hoary shell]

ok

[jagged quartz]

I think chat gpt is actually OK at git - but if your question is really advanced, i honestly think stack overflow is a better forum for git

[austere yacht]

How about one of the bazillion tutorials and the documentation?

[brisk mist]

someone can help me? im hosting an api in versel free and when I use thunder client to look if is working and it is works well, but when I use in UnityWebRequest it get an error of Authorization (401). I dont understand why... here some

[astral spear]

It dont work

[sharp axle]

Something is wrong with your server then

[sharp axle]

That probably means your bearer token is incorrect

[brisk mist]

but when I use the localhost with the api on my pc this not happen

[keen briar]

i'm making a multiplayer vr and non vr game

how do i make player prefabs different

for both

vr players

and non vr players

why did nobody respond after i saisd hat

[warped pilot]

HeyHello, I have a question, with the lobby system, is an event triggered when the host leaves the lobby that I can use to restart my relay?

got it

Post your spawning code here and we can take a look at it

[keen briar]

here i posted it

[sharp axle]

I'm still not clear on why you aren't using NGO. It's literally less code than what you have here

But this is just your connection code. Do you have any code to spawn the player at all?

[astral spear]

Got a question if i were to commission someone related to fix this problem... Whats the right price for it?

[sharp axle]

Depends on where you live. Hiring a server engineer in the US is like at least $100k/year at the very low end

[sterile creek]

$50-150 an hour for a U.S. based engineer

You will find cheaper on places like up work, but goodluck haha

You need to send http requests, likely using something like long polling. You could also setup a socket connection and keep that alive for communication but it’s pretty complicated if your not using a library.

For Quantum Chess, my team used http requests with a rest api using flask and app engine and it worked nicely. All the multiplayer runs through it but there is no peer to peer connection

[livid nexus]

Anyone here familiar with fishnet that I can DM to discuss and issue ive been stuck on?

[dusk isle]

Need some guidance for Final Year Project - Multiplayer Sudoku App

[mortal elm]

I am having a few very very annoying problems

1. A GameObject is coming up as null when I try to set it active, when it is dragged and dropped and i see it in the editor

2. A script can't seem to find the photon view component that is in the same gameobject, the same script has an issue where it randomly Disables (presumabely) after awake as it doesn't run Start() - to counter this I literally had to do public override void OnDisable() this.enabled = true;

[astral spear]

Good god.

[keen briar]

the code spawns player on starthost() or joingame()

automatically

i think

because multiplayer hlapi

[analog tide]

Hello i'm having a little issue with my code so here is the problem :

[Rpc(SendTo.ClientsAndHost)]
    public void CreateBulletRpc(Quaternion weaponSpawnerRotation)
    {
       [...]
    }```

When i try to make it a serverRPC with ne permission needed so all my client can use it, it won't work  but when i make it a classique RPC the says that i need to be the server to spawn the bullet, 
About a week ago it worked i made some changed playing solo and not testing it on a server and now the client can't shoot some bullets.

My script is attached to the player have a network object and is a network behaviour

[fluid walrus]

only the server can spawn things, so if you're spawning the bullet as a network object you don't need to send the RPC to clients too, send it to only the host

[analog tide]

i'll try this

[analog tide]

well it works not i have an other issue but i can now see why

[tawny briar]

Why??

using 1.2.0-pre.12

I am trying to not create client / server worlds until I explicitly create them but it just keeps creating them as soon as I hit play

I have added the Override Automatic Netcode Bootstrap component and set it to disable but it makes no difference

[analog tide]

I'm back, i now not have the same error as this morning, and now i have a rotation but it can't spawn and i don't know why

here is the code :

public override void OnNetworkSpawn()
    {
        if (IsOwner)
        {
            enabled = true;
            playerController = GetComponent<PlayerController>();
        }
        else
        {
            enabled = false;
        }
    }

private void Update() {
        if (Input.GetMouseButton(0) && weapon != null && !isReloading && Time.time - lastShot > weaponFireRate && weaponAmmo > 0)
        {
            lastShot = Time.time;
            CreateBulletServerRpc(weaponSpawner.transform.rotation);
        }
    }

[ServerRpc(RequireOwnership = false)]
    public void CreateBulletServerRpc(Quaternion weaponSpawnerRotation)
    {
        {
            Debug.Log("Creating bullet at " + weaponSpawnerRotation);
            RaycastHit hit;
            if (Physics.Raycast(GetComponent<PlayerController>().myCamera.transform.position, GetComponent<PlayerController>().myCamera.transform.forward, out hit, 1000f))
            {
                Vector3 dispersion = new Vector3(Random.Range(-weaponDispersion, weaponDispersion), Random.Range(-weaponDispersion, weaponDispersion), Random.Range(-weaponDispersion, weaponDispersion));
                GameObject bullet = Instantiate(bulletPrefab, gameObject.GetComponentInChildren<WeaponParts>().weaponMuzzle.transform.position, weaponSpawnerRotation);
                bullet.GetComponent<NetworkObject>().Spawn();
                bullet.GetComponent<BulletScript>().bulletSpeed.Value = weaponSpeedBalisitic;
                bullet.GetComponent<BulletScript>().direction.Value = (hit.point - gameObject.GetComponentInChildren<WeaponParts>().weaponMuzzle.transform.position).normalized;
                bullet.GetComponent<BulletScript>().damage.Value = weaponDamage;
            }
            else 
            {
                GameObject bullet = Instantiate(bulletPrefab, gameObject.GetComponentInChildren<WeaponParts>().weaponMuzzle.transform.position, weaponSpawnerRotation);
                bullet.GetComponent<NetworkObject>().Spawn();
                bullet.GetComponent<BulletScript>().bulletSpeed.Value = weaponSpeedBalisitic;
                bullet.GetComponent<BulletScript>().direction.Value = GetComponent<PlayerController>().myCamera.transform.forward;
                bullet.GetComponent<BulletScript>().damage.Value = weaponDamage;
            }
        } 
    }```

I have this : Object reference not set to an instance of an object 

I did put my weaponSpawner at my gameobject my scripts are children of my gameobject

[tawny briar]

I apparently needed to add an override of my own:

[placid onyx]

clean up your code first! don't repeat GetComponent all over again, do it once, assign to variable. It's faster and way more readable because you don't end up with code where 50% of the text is a repetition of the lines before and after. It makes it hard to spot issues as well, like the nullref.
the error message tells you the line, but with one line containing possibly 5+ references that might be null this is hard to spot - if you clean the code to have 1-2 references per line, you'll spot these issues right away because there's no second guessing anymore

[placid onyx]

btw the IDE can help with cleaning, for instance "extract variable" to create a variable from a method that returns something

[errant bramble]

Backdash - new C# rollback netcode library

I've been working on a dotnet library for rollback netcode, widely used by fighting games to accomplish a better P2P multiplayer experience

I based my implementation on GGPO which was the pioneer in this type of netcode

More about why it is good and how it works here and here.

It is very early and needs more testing. but I believe it looks good enough to share 😅

https://github.com/lucasteles/Backdash

Demos:

• local network demo
• online lobby demo

Unfortunately, it does not work with Unity until they finish the CoreCLR port.

[stone granite]

What you recommend for multiplayer with ECS DOTS? Photon Quantum or Netcode or other?

[sharp axle]

Can't recommend Netcode for Entities unless you are already all in on DOTS. Netcode for Gameobjects is awesome though

[stone granite]

I am switching from other engine, but I need to use ECS because I will have lot of Units in my 2D RTS game

[mint anvil]

another stupid question from me :p
so i have a script that has a value controlled by an interface called Mod

public NetworkVariable<Vector3> waypoint;
    public Vector3 Waypoint
    {
        get { return waypoint.Value; }
        set { waypoint.Value = value; }
    }

and the other one is supposed to set this value:

    [ServerRpc(RequireOwnership = false)]
    void SetWaypointServerRpc(NetworkObjectReference ship, Vector3 waypoint)
    {
        GameObject selectedShip = ship;
        selectedShip.GetComponent<Mod>().Waypoint = waypoint;
    }

but i get this error:
InvalidOperationException: Client is not allowed to write to this NetworkVariable
even tho it's a server rpc ... ?

[sharp axle]

If you are getting this error then it means that its not a network behavior or the network object is not spawned

[mint anvil]

hmm ok thx i'll look at it

[pearl swallow]

Hey guys, I am using photon Fusion and I have been trying to replace mesh of a Network GameObject.
After reading the documentation seems like only general data types like int, float, color, vector 3, etc can be changed dynamically for all clients.

So I tried to turn on/off game objects but that does not get reflected to all the clients as well.

Anyone knows the solution?
Wanted to create a game like prop hunter where you can change the mesh.

[fluid walrus]

you could make an array of meshes somewhere, and sync the index of the mesh in the array as an int instead of the mesh itself

[livid nexus]

Hey i am using fishnet. Any idea why I can load into new connection scenes just fine, but when i try to load one that I previously came from, everything in the scene is disabled?

[pearl swallow]

Ohhhhh, I see thanks. I’ll try this out.

[hushed terrace]

Hey guys anyone in here any experience with building a Server authoritative server ? Im trying to figure out how to use Unity.Services.Authentication.Server namespace because i have 3.3.0 auth package installed and the namespace is not showing ... I dont understand why ...

[past matrix]

Hey, how do I make that enemy cards from your perspective are on the top and from enemys perspective your cards are on the top for them? I want to make turn based card game, and I want for player that their cards will always be seen on the bottom.

[sharp axle]

Kinda depends on your setup. If this in done all in world space with each card having a network transform then you would only need to alight the local player camera

If you have the cards as sprites on a UI canvas then they shouldn't be networked and the UI would be updated by like a NetworkList of cards for the player hand, board, and decks

[naive gyro]

How do I make a walkie-talkie using Photon Voice?

[warped pilot]

Hey when I StartHost he spawns my player prefab. How can I change it to spawn it manually ?

[sharp axle]

Remove the player prefab from the network manager then you can call . SpawnAsPlayerObject ()

[warped pilot]

what do i have to fill up as client id ?

[sharp axle]

That will be the client id of the player you want to spawn

[wild mortar]

why do io get error Cannot complete action because client is not active. This may also occur if the object is not yet initialized, has deinitialized, or if it does not contain a NetworkObject component.
UnityEngine.Debug:LogWarning (object)
https://hastebin.com/share/gubejavevo.csharp im using fishnet

[livid nexus]

How can i make sure that when the host and a player are in a different scene, that the host isnt seeing the lighting from both scenes?

[haughty heart]

Scene lights affect all scenes. You need to create the logic for turning off lights you don't want.

When a scene is loaded, find the lights in it and disable them if you don't want them on

[placid onyx]

possibly calling an action before the client has spawned on the network?

[stable shadow]

I am using Mirror and kcp as my networking/transport protocall. It's been working great for months but starting today the client can no longer connect to the server and I haven't been able to debug why
Things I've checked confirmed to be fine:

• I can ping my external ip, no issues there
• The server network address is my external IP
• router firewall has an exception for my local ip on the correct port
• the version of unity itself is firewall excepted

I did notice my local ip the last 3 digits had changed, but I made sure to update everything to the new local address (server, port forward) and cmd pings go through just fine

I was able to connect to myself with the local IP so the server functions there, but networked IP connection doesnt go through

unity.exe has a firewall exception as well made sure of that

[astral spear]

how do i fix this?

[astral spear]

how do i fix this?

[mint anvil]

helo, another question:
the debug works and i run the function

Debug.LogError(selectable.name + waypointPosition);
SetWaypointServerRpc(selectable.gameObject.GetComponent<NetworkObject>(), waypointPosition);

but the "called" debug never happens, so the function isn't working

    [ServerRpc(RequireOwnership = false)]
    void SetWaypointServerRpc(NetworkObjectReference ship, Vector3 waypoint)
    {
        Debug.LogError("called");
        GameObject selectedShip = ship;
        selectedShip.GetComponent<Mod>().Waypoint = waypoint;
    }

do you know why?

[ocean tapir]

Hello there im trying to use a severRpc to move an object by adding a force to it. however when i do it increase the veloctiy but doesnt change the transform postion at all any idea why this is

public void movementServerRpc(Vector2 m,ServerRpcParams serverRpcParams = default){
var clientId = serverRpcParams.Receive.SenderClientId;
if (NetworkManager.ConnectedClients.ContainsKey(clientId)){
var client = NetworkManager.ConnectedClients[clientId];
client.PlayerObject.GetComponent<Rigidbody2D>().AddForce(m,ForceMode2D.Force);
Debug.Log(client.PlayerObject.transform.position);
}
}

it is called in update if isOwner

[sharp axle]

Looks like you are already logged in on that PC

[astral spear]

Yeah but why its red and not lettin me in the damn server

[sharp axle]

You would only see "called" on the server console

[sharp axle]

You can not log in twice from the same PC

[astral spear]

Thats the thing. Ik this must be simple to you but how do i fix it then?

[sharp axle]

Log out of Epic on that PC

[astral spear]

Ohhh wait wait. My pc is login on it and my laptop is log in too

So there must be only one...

[astral spear]

Right?

[sharp axle]

Seems that way. Steam does the same thing

[astral spear]

So i should log out my unity on the other pc then aight aight

[mint anvil]

yeah on server i get only this:
[Netcode] Deferred messages were received for a trigger of type OnSpawn with key 0, but that trigger was not received within within 1 second(s).
no clue what this means

[sharp axle]

That is usually when an RPC is called before that object has spawned. Make sure it's being called in OnNetworkSpawn() or after

[mint anvil]

wait maybe i found the issue (i am stupid)

i didn't spawn the player because i thought i don't have to, it's a strategy game and the players are cameras, and the code to set waypoint per click is on that

[mint anvil]

soooo now the problem is the only player prefab is the local player, the other players are not spawned automatically, and if i do it manually they delete itself

[sharp axle]

Are you spawning the player in the network manager?

[mint anvil]

what do you mean by that (i have the player prefab assigned in the network manager)

[sharp axle]

Do you have the player prefab assigned in the network manager so it will automatically spawn players?

[mint anvil]

yes i have (i edited my message before you wrote the message xD)

[coral rose]

hi everyone Im currently playing with Netcode in Unity but have a problem, when the Client connects to the Host this Error Message accurs : " [Netcode] Trying to receive NamedMessage from client 0 which is not in a connected state" Does someone possibly know an answer to this problem or could help me out in some way or another ? Any help would be appreciated

[sharp axle]

Are you calling a RPCs inside ofth OnClientConnected callback?

[coral rose]

no im not how do i do that ?

[sharp axle]

No, You don't want to do that because the client is not fully connected then and you'll get that error message

[coral rose]

But im not doing that and i still get the error message

[coral rose]

Can i send you the code so you can get a look at it ?

[sharp axle]

hi everyone Im currently playing with

[misty totem]

Does anyone know a way to get more detail on this fun little error?
[Netcode] NetworkConfig mismatch. The configuration between the server and client does not match
I'm running two servers hosted on unity multiplayer hosting and when i try to connect them to one another I get this error and I have no idea why.
The client on my pc connects to them fine but the two servers can't seem to link to one another

so if i could figure out what unity thinks the mismatch is that would be very helpful in fixing it

[sharp axle]

I don't believe this is possible. Multiplay Server Hosting does not support direct server to server connections.

still would be useful if netcode gave a little more detail on what it thinks is mismatched 🤔

also if that's the case it's weird that is the error I'm getting - rather than unable to connect/ connection rejected or something

[hidden spear]

Hey everyone, I am wanting to develop a 2D roguelike multiplayer game and am intending to upload it onto steam. I'm reaching out to get someone's opinion about the multiplayer aspect of the game. I don't know anything at all about multiplayer and don't know where to start. Should i use unity's multiplayer intergration or is there a better / more reliable solution to create multiplayer. Since this would hopefully become a steam game i would also need to compensate for user profiles when wanting to play with friends. if someone could maybe give me a sense if direction of what to do i would really appreciate it. If you require more information to fully understand what i would be using from the networking please do DM me and i would really be thankful for any help. Thanks.

[ripe mesa]

you need to tell more about your game

is it a shooter? what is your player count? platform target? how fast paced it is? what about your game security?

[hidden spear]

it will be a rougelike , 4 players per lobby , pc , will start off decently slow - there will be boss fights and towards further stages more enemies would spawn and game might get decently "stressful" / fast, still getting to game security based of networking.

[ripe mesa]

Yes rougelike, like hack n slash, or shooter?

How many entities? Or Enemies are expected

Its a game usually played with friend ?

[hidden spear]

hack n slash, its like dungeon themed

but might implement crossbows or magic projecticels at some point

[hidden spear]

yes, basicly u would create a lobby then u can launch solo or with friends

[hidden spear]

well it depends on the stage, liek at the begining they will spawn slow... id say maybe up to 200 enemeies in later stages?

[ripe mesa]

It can be 200 enemies at the same time?

[hidden spear]

ig so

i have kind of been "making the game" with PUN photon. i have had people tell me to use fusion and ive seen people use mirror asset( for steam and stuff), so thats why im askling for guidence

[ripe mesa]

Will the game published on steam?

[hidden spear]

i hope to do so, but it depends on how well i can make the game. i am still a student at school and i kind of have taken game development as a hobby and self taught everythign i know so far. My main goal for this project was to chalenge myself and see how it is becuase i do have a passion for coding.

[ripe mesa]

If the game is published in steam, you will have a huge perks on multiplayer game

You can use the steamworks networking to allow players to connect together

If you use Photon products you dont have to worry about any of this.

While if you use other netcodes (Mirror,Fishnet,NGO,Netick,Mirage) you will have or must use a relay services to allow players play together

Steamworks is one of the relay services I talked

Its free of charge if yoh publish ur game on steam

[hidden spear]

so what is the best option, steam networking?

[ripe mesa]

Id recommend you Fishnet, Mirage, Mirror, or Netick

If you dont want spagehtti code, use Netick

[hidden spear]

so im thinking using mirror with fizzy's steamworks, anything else i should keep in mind if im going down that path

[sharp axle]

I would say that in the end of comes down to price and personal preference. Unity Relay and Lobby has fairly generous free tiers and is cross platform if ever plan to release to mobile or consoles. Unity Netcode can also work with Steamworks.

For networking in general, try to keep things as data oriented as possible. Your life will be a lot easier if you serpates the game data from the game logic

[scenic dock]

can i rotate child object locally in netcode?

i cant move my camera up and down

[willow scaffold]

Is it possible to use client as a host with Webgl or do I 100% need a dedicated server to host my game?

[sharp axle]

A web browser can not be a host. You can use the Relay Service to get around that though

[willow scaffold]

What is Relay Service?

[sharp axle]

https://docs.unity.com/ugs/en-us/manual/relay/manual/introduction

You can use any other relay service as well

[willow scaffold]

Thanks

[scenic dock]

can i hide object from the owner?

[sharp axle]

As long as the owner is not the host, I believe you can.

[dense echo]

hey i was using photon pun2 and using IPunOwnershipCallbacks Interface Reference

but am getting this error Assets\SyncMaterialChange.cs(39,26): error CS0115: 'SyncMaterialChange.OnOwnershipRequest(PhotonView, Player)': no suitable method found to override

[weak plinth]

Is there a way to replicate XR hands reliably over a network?

I have seen samples of 'controller hands' which are driven by animators, which can easily be replicated over the network, even client-authoritatively (see Valem Tutorials).

What I am interested in is actual hand input being recorded procedurally and replicated.

[naive gyro]

I'm making a multiplayer game using Photon and when I click on the button that should open another scene, the scene either takes a long time to open (in rare cases) or doesn't open at all and gives this error - Connection lost. OnStatusChanged to DisconnectByServerTimeout. Client state was: Leaving. SCS v0 UDP SocketErrorCode: 0 AppOutOfFocusRecent WinSock

here are the logs of my game

[naive gyro]

but when you go to a scene where there is nothing, it's fine.

I would also add that in Unity Editor I have everything loads normally and fast enough without any errors.

[rapid crater]

I was under the impression that Mirror, as it is in uMMORPG allows for local co-op without the need for a relay server. Just one of the players acting as server and player

[ripe mesa]

that could work, but thats irrelevant

[rapid crater]

Not to me it's not 🙂 (for what i am trying to do, i mean)

[glacial condor]

Hi all, I work for an escape room and we're trying to to implement a program that will help our gamemasters see the progress of one of the games inside the room and be able to help them remotely if needed. I'm new to networking in general so I'm trying to get the easiest solution to this, many of the examples go straight into player movement and things not needed in this scenerio. Currently I have net code for unity installed but I've peeked at photon fusion which just seems a like a lot for the little that I'm trying to achieve. If someone knows of something similar I can replicate or a good guide on simple data transfer across a local network, pls let me know, ty 😊

[naive gyro]

I'm still waiting

[wraith olive]

Is this an irl escape room? If so why are you using unity? I guess NGO does make basic data transfer very simple.
Anyways netcode for gameobjects (the unity provided thing) works great in my experience

[glacial condor]

Its irl. We have a console prop that we're swapping out its gatekeeper to a unity program. The cameras don't pick up the screen so this is just for quality of life for the game master. Thank you for the response!

[visual hull]

Guys, what approach should you use? First, the client connects to the server (netcode), and then authorizes itself by entering the login and password or before connecting to the server (connection approval from netcode)

[sharp axle]

Depends on how you are authenticating. If using Unity Authentication then I would do that first

[visual hull]

I use that system: Client -> Server -> web server -> MySQL without unity auth

[sharp axle]

as long as you are encrypting the password you can do it through Connection Approval. You can keep your authentication web server from being public facing

[visual hull]

btw it is possible to use async operation in connection approval?

[sharp axle]

Pretty sure you can. You would need to set response.Pending to be true

[tawdry trench]

i control the other person and he controls me for some reason

Do you check IsOwner value in your script?

Idk why but all my ui elements are just infinitely duplicating with netcode.

Like I have a text ui and on runtime it just constantly duplicates and I'm not sure why.

[sharp axle]

Do your canvas or ui elements have a network object on them?

[wanton forge]

No.

[placid onyx]

possibly duplicating per connected client, or per spawned object?
sounds like a typical if (IsClient) but not considering the object spawns for every client so you may need to do an if (IsOwner) check instead

for instance if your player prefab contains ui HUD elements, these will be shown by default for both the owner and all other players unless you only enable them for the local / owner player

[storm sierra]

Hello all, question regarding cameras and netcode - when i add a new client, the camera from the previous client switches to the camera of the new client... any idea how to fix this?

[placid onyx]

you probably spawn a camera for each client but not enabling the camera ONLY for the local/owner player

[wanton forge]

so like if not ovner then disable the interface?

thing is it is duplicating even before any host / client vhich is really weird

[placid onyx]

no don't overcomplicate 😉
if (IsOwner) then enable ...
it's better to leave components disabled in the prefab and enable as needed, avoids them doing things in Start or OnDisable/OnDestroy that you don't want to run in the first place, and the code is simpler.

[storm sierra]

Ok so, if (!IsOwner){
MainCamera.enabled = false;
}

Not sure how to go about this

[placid onyx]

exactly but negate that, see above 😉

[storm sierra]

Oh wow hadn't thought about starting them as disabled cool trick

[placid onyx]

I have a componen for that ... EnableOnNetworkSpawn or similar

that's the one: https://github.com/CodeSmile-0000011110110111/de.codesmile.netcode/blob/main/Runtime/Components/NetworkSpawnEnableComponents.cs

I then just drag the disabled components onto it and they get enabled when it spawns for the owner

[storm sierra]

awesome

thank u

Subbed to your Youtube 🙂

[midnight pebble]

does netcode for gameobjects work with steamworks.net? What transport do I have to get?

[wanton forge]

solved nothing. Also I don't think this is the case anyway as it is replicating infinitely. Not twice.

And also it replicates before there is even a single client.

[wanton forge]

^ fixed

However I am running this serverrpc but it still errors that it can't access connectedclients from the client?

[storm sierra]

I still havent fixed my camera issue. Well I have, but only by unselecting a camera in the inspector during runtime.

the camera for the new instance starts as on, but when i turn it off in the inspector it works perfectly, i just need to know how to disable the camera of every new instance

[sharp axle]

You can find a couple of Steam transports here
https://github.com/Unity-Technologies/multiplayer-community-contributions

[sharp axle]

On the player's OnNetworkSpawn() if(!IsOwner) disable the camera

[fickle magnet]

So in my open world multiplayer game I need some advice.

1. I'm using NetworkTransform for my enemies and they tend to move around choppy and laggy for other players. Should I just make my own thing?
2. If I have like 8 players running around in different parts of the world, I need to have all these enemies near each player active on the host end? I'd like to not do this so host doesn't have more processing done, but prob have to do this.

#2 prob isn't explained too well. But normally I have all enemies disabled while player is not nearby but since it's multiplayer and if you have many players running around in different areas then they have many enemies active around them but to keep it in sync it all goes back to the server then host. (I do hotseat hosting cuz i don't have $$ to run a server)

[scarlet venture]

i recommend looking into the details of Netcode for Entities, and the new Megacity Multiplayer (128+ players) sample game that uses it.
their cloud hosting services have a free tier, and the costs, once your game becomes busy, looks very reasonable.
better than Amazon generic cloud services.

(also you don't NEED their services to use NCfE)

[visual hull]

Hey its a normal bug? Because I see this message only in client but prefab was spawned on client and server side

[half sage]

what network solutions would you guys recommend for a 2d topdown game with a max of like 4 players? i'm very new to networking, is pun 2 good?

[placid onyx]

check the NetworkPrefabs list for any missing prefabs

[placid onyx]

any will be fine, pick the one that has the most tutorials / documentation / community support
currently I'd say that's NGO

[visual hull]

Client and server have this prefab in list

And that same config for server / client

Idk where is problem its a bug or what?

[sharp axle]

I don't know if it's causing this particular bug, but netwpr!kmg the entire XR rig is going to give you trouble.

[lavish canyon]

yall i am going insane wth is this

the script just has a network variable and a couple other fields

it looks fine in the inspector after i save the script, but when i click off the object its attatched to and select it again, it gives me all those errors

these are the only flieds i have

it looks like it works as intended if its a serialized private field, but when its public it does this. w h y

[sharp axle]

Looks like an editor bug. Should probably update to the latest version 1.8.1

[lavish canyon]

ah, okay. thanks

[signal bone]

I have a network object pool, and the server spawns the objects and adds them to the list of gameobjects in the pool

however, on the clients their list is obviously empty

what is the best way to make sure the list of gameobjects in the netwokr object pool are the same as the list on the server?

[bright remnant]

what networking solutions would your recomend

[visual hull]

Finally, just deleting the NetworkManager object on the server and client and creating it again fixed the problem at the moment. It is a bug

[wanton forge]

I am running this serverrpc but it still errors that it can't access connectedclients from the client?

[sharp axle]

You shouldn't have to do anything on the clients for Network Object pool. Clients will just Spawn/Despawn like normal.
https://docs-multiplayer.unity3d.com/netcode/current/advanced-topics/object-pooling/

[sharp axle]

RPCs can not return a value. You would need to call a clientRPC if you wanted to send that value back to the client

[wanton forge]

(Made the return value instead just a debug log and the method is now void)

[bright remnant]

can anyone answer my thread

[sharp axle]

Make sure LobbyHandler is a Network Behavior and is on a spawned Network Object

[wanton forge]

It is

[signal bone]

They need to access the network object for client prediction

For example I have a grappling hook projectile

And on the client it was clunky for the them to press the button but the projectile spawns a little later so I had the client simulate forward with the grappling hook projectile until the server sends an update

But the way I did that was through on the grappling hook spawn for the client, it would search for all player scripts in the game and compare the owning client ids and if they match then it adds the projectile to the pool

But this seems like a weird solution???

[sharp axle]

If you are instantiating objects locally for the client then it shouldn't be networked. But also does a grappling hook need to be pooled? I would think that it would be only one per player at a time.

[signal bone]

The client is not instantiating the grappling hook object, they are using the same one as the server so that when the server eventually shoots the grappling hook it will send back a position update and the client projectile will be set to the servers

[signal bone]

Also yes, in this case the grappling hook does not need to be pooled, but regardless how would I get a reference to the grappling hook on the client?

[sharp axle]

if the server is spawning it then you would use Network Object Reference
https://docs-multiplayer.unity3d.com/netcode/current/advanced-topics/serialization/networkobject-serialization/#networkobjectreference

[signal bone]

Hmmm so the server spawns the player object, then inside the player object the network pool spawns a network object

Then the server sends that network object in an rpc to the client? And the object pool assigns that network object into its list of game objects?

[sharp axle]

If you are using the Network Object Pool I linked to, you don't have to do any of that. Spawn()/Despawn() will handle all the pooling for you.

[naive gyro]

I have a problem, I use Photon and I made a menu where players can create or enter a lobby, but when I try to do PhotonNetwork.LoadLevel(); in the game itself, all players go to the specified scene, but do not see each other.PhotonNetwork.LoadLevel(); only works if the button is clicked by MasterClient.

[sharp axle]

I don't use Photon but normally only the Host should be changing the scenes

[tough drum]

Hi, im currently following the multiplayer Tutorial from CodeMonkey
He says to install ClientNetworkTransform from a git url but my unity doesnt do anything after I try to add it.

[sharp axle]

You dont have to go through GitHub for that. You can just copy the code from here
https://docs-multiplayer.unity3d.com/netcode/current/components/networktransform/#owner-authoritative-mode

[tough drum]

i dont understand what i have to do with that code

[sharp axle]

That is the Client Network Transform

[tough drum]

but what do i do with that :/

[sharp axle]

You can use that to follow the rest of the tutorial.

[tough drum]

okay :)

Hi, I'm making a multiplayer game that uses additive scenes for different things (like UI, Level, Gameplay, etc.), but I'm having some problems synchronizing the active scene that's being loaded. On the server/host the correct scene is being set as the active one, but the clients are not being synchronized and have the wrong active scene.
I know there's the NetworkSceneManager.ActiveSceneSynchronizationEnabled property which is supposed to do exactly that as far as I understand, but I've tried setting it to true both on the server and the clients, but nothing changed. I don't even get any SceneEvents of type SceneEventType.ActiveSceneChanged

[blissful trout]

I'm working with FishNet and managed to set up the absolute basics with initializing new players at a spawnpoint, but player actions are not syncd up. I can't see when one opens the door, and I can't see either move from the others perspective. Where do I need to start to sync actions?

[ember berry]

can someone help me. i am building a 2 - player multiplayer game using the matchmaker service of UGS. Problem i am facing is whenever someone starts matchmaking by generating a ticket and leaves/exits the game before a match is found, the ticket generated by that player is still present in the matchmaker and gets matched to someone else even when the first player has now exited the game.

i am using the following code :

private async void OnApplicationPause(bool pause)
    {
        if (pause == true)
        {
            if (matchticketid != null)
            {
                print("pause Started");
                 await MatchmakerService.Instance.DeleteTicketAsync(matchticketid);
                  
                    print("paused");
            }
        }
        else
            print("not paused");
    }

however only "pause Started" is printed on the android logcat when game is minimised and the actual function of MatchmakerService.Instance.DeleteTicketAsync(matchticketid) and subsequent "paused" is only printed when i reopen the game.

can someone tell me how to solve this issue with the code or suggest me a different approach to my problem??

The game im making will give the player the option to type in a world name, and the game will check the database to see if that world exists, if it doesnt then the world will be created, and a lobby will be created and the lobby will delete itself when there are 0 players in that world

if a player tries to join an existing world, the game will check if a lobby exists for that world, and if there isnt then it will create a lobby, is this the most optimal way to go about doing this? if not id appreciate a better way

[severe spear]

whats the biggest packet size i can serialize over the network (for onsynchronize)?

[severe spear]

netcode seems to just... not work how it says it should?

im looking at this (highlighted part is important)

on a late join, onnetworkspawn is invoked

i dont care when, the point is that it gets invoked

however, its not being invoked for me

nor is OnSynchronize

but only for the client, it fires on the server

[sharp axle]

Are you seeing any error messages in the console? Also make sure that you are not calling LoadScene () on the clients. The network manager should be handling scene syncing?

[severe spear]

i found it after a lot of troubleshooting... apparently theres an error being thrown on synchronization and caught by netcode, so it flew under the radar when testing in a debug build

its probably due to passing a string instead of a fixed string to a serializer

[unique gorge]

I am new here. Is it better to use netcode for objects or netcode for entites? I ask this for my 5 vs 5 shooter game.

[placid onyx]

Not surprised since Debug.Log spam 60 times per second and printing it to the console slows the editor down, network or not.

[placid onyx]

Why are you instantiating UI on the server? That makes no sense, typically the server isn't supposed to even render anything.
Also you cannot simply Destroy a spawned network object, you have to despawn it. In general: don't spawn it in the first place if it isn't supposed to be spawned.

[wanton forge]

I mean I just changed it to simply if it is the owner and still on the client there are 2 instances of it that are spawned.

[sharp axle]

You would only use Netcode for Entities if you are already using DOTs for your game

[unique gorge]

Thanks

Is there better netcode for multiplayer games?

There really isn't any best netcode. Some have more built in features than others but they all will work for a team shooter.

[wanton forge]

You can't spawn network objects on the client btw.

Please help someone because I haven't botten a proper answer yet.

This spawns 2 of the ui object to the client, when there should only be 1.

If this is on the player, the Instantiate and Spawn() should be in a RPC. I don't know why OnNetworkSpawn would be called twice on the client. The host would have it called twice normally.
Your UI object probably should not be network objects in any case though.

[wanton forge]

I need the ui to be different for some players.

As well as to update different players' ui respectively

which I can't do based off of one object.

[wraith olive]

Just sync a state that tells what UI a player should be seeing and then the UI can also read what data you need it to display from the rest of your game

UI should almost certainly stay client-side otherwise

[severe spear]

hey, im trying to send some data with a custom message handler, and everything works fine if the recieving client is the sending client

like, sending it to myself

i recieve it properly

but the data is nonsense if it gets sent between clients

packets get sent like this cs public void SendPacket(IPacket packet, ulong clientId = 0) { NetworkManager.Singleton.CustomMessagingManager.SendNamedMessage( packet.Type.ToString(), clientId, packet.Serialize(), NetworkDelivery.ReliableFragmentedSequenced); }

they are reliable

im probably not recieving them right but i dont know how to with fragmented messages

[stable dust]

so i have extra items like hats and stuff turned off locally which works but then the shadow doesnt show the missing hat

is there any way around this?

because otherwise the hats and stuff block player vision

[sharp axle]

if packet is also implementing INetworkSerializable then you shouldn't need to call Serialize() on it

[sharp axle]

You probably need to use a RPC to disable those items

[severe spear]

Serialize() is a custom function to convert it to a FastBufferWriter

in the case of the specific packet im sending thats causing problems, it looks like this:

        public FastBufferWriter Serialize()
        {
            FastBufferWriter writer = new(File.GetSize(), Unity.Collections.Allocator.Temp);
            writer.WriteNetworkSerializable(File);
            return writer;
        }

File is an INetworkSerializable, it gets serialized properly when sending locally

like, the client id target of the message is the same as the sender

but when its recieved by a different client, the data is jumbled

none of it deserializes right and it overflows

the size of the buffer is right though, oddly enough

it goes through this but none of it deserializes right

[severe spear]

to deserialize it, it does this btw

it just peeks the file type to deserialize using the proper class

the data is just total nonsense, a fixed string's length property is just some random number in the tens of millions

oh shit i think i found the problem

the data starts at position 8 but i seek to 0

this didnt fix it... which is unsurprising considering it didnt cause issues locally

it seems like it might be an endianness problem?

but i dont understand why it would only be a problem when sending to other clients, if its all through the same messaging syste,

[severe spear]

i fixed it somehow? but i honestly dont know what i changed

oh wait, right

it was working all along but it was using the same buffer twice by accident

so i was getting errors from the second one

[twilit root]

Does most discussion in here focus on netcode implementation or networking concepts in general? I've started using and finding success with fusion 2 and wondering if this is a suitable place to discuss those questions and issues,

[earnest hinge]

I have a spaceship with players inside that can move around whilst the spaceship itself is also moving and rotating. However currently when the spaceship is moving, players and especially clients physically lag behind it and jitter. Could someone give me a general idea on how I could prevent this lag and have players move with the ship smoothly?

[warped pilot]

Hey how can I change this variable in inspector ? private NetworkVariable<float> m_CountdownTimer = new NetworkVariable<float>(5f);

[sharp axle]

I would say general networking questions are fine. But Photon specific questions would be better on their own server

[vagrant girder]

are there any recommendation for non-real time game backend services ? i have tried Nakama, it seems fine but the debugging support is really not ideal so im looking for alternative

[sharp axle]

Syncing transform on a moving platform is super tricky. One way is to parent the player to the Ship but I think you'll have to disable interpolation

[sharp axle]

make it public or use [SerializeField]

[sharp axle]

Unity Cloud Code, AWS Lambda, or Playfab Cloudscript (Azure Function)

[earnest hinge]

What will disabling interpolation do and on which objects would I need to disable it on? I'm not very familiar with NGO

[sharp axle]

Interpolation attempts to smooth the movement of the Network Transform. This can cause a problem when you need it locked to a local position

[twilit root]

Thank you for the response. In general, if I am building a 1v1 card game with max of two players in room, what're the pros/cons of using host/client vs shared room setups?

[sharp axle]

If shared rooms are dedicated servers, then the biggest tradeoffs will be cost and security. The Host will be in full control of the game state and there is not much you can do about that. If its a pure card game then you can go with like NodeJs or some serverless solutions I listed a few posts up

[wanton forge]

Can someone here just explain to me in depth how to use ui for each client without using it as a network object. Answers I've only gotten so far basically just say "Handle the ui from the client and that's it".

I was using it as a network object but now I am getting TONS of stupid errors that I can't seem to resolve

Also how am I supposed to have a NetworkBehaviour script inside it without it being a network object?

[sharp axle]

I have a UI Manager script that is its own network object. It will grab a reference to the local canvas in its OnNetworkSpawn(). The UI manager will be the one subscribing to network variables and containing the RPCs needed to update the UI

[spring void]

You can store a reference to the network object of the player who's supposed to be the owner of the UI. That way you can communicate with the server indirectly via that network object. You can also create some UnityAction or UnityEvent and subscribe it with your UI so it can be refreshed whenever that UnityAction or UnityEvent is invoked.

[sharp axle]

Events are great for decoupling UI

[zenith hatch]

I read some of the resources and this is pretty intimidating

[sharp axle]

Networking is not for the faint of heart. Its just a steep learning curve. Once you get your head around it, it'll become second nature

[lavish scaffold]

how can i sync UI buttons across host and client?
if one is disabled for one client then it should be diabled for the other client too

[placid onyx]

You sync the enabled/disabled state, netvar or rpc. UI shouldn't be networked, it just responds to state change either through events or polling.

[placid onyx]

UI should always be non-networked. UI is just that stupid sprite renderer that takes some data and displays it, like player health. So you really only need to synch the data, or the actions. The UI only needs to know where to find that data, either to pull it every frame or (better) to hook into netvar changes or other gameplay events.

[lavish scaffold]

i have a network manager in a different scene
but i want to disable the buttons in another scene
will that be possible?

[placid onyx]

If the UI is a card being drawn (common use case) then the game state changes from "card in player's hand" to "card played on table". That's an event sent via RPC. The card UI responds to that by animating its movement from player hand to table for every client.

[placid onyx]

You cannot have a NetworkManager "in a different scene". It's a DontDestroyOnLoad object and remains in that DontDestroyOnLoad "scene" once it has been initialized - which should occur at the start of the game.

[lavish scaffold]

ohh then that means i can access it from any scene

[placid onyx]

yep, it's NetworkManager.Singleton remember? 😉

[lavish scaffold]

got it thanks

i am actually trying to make a mutliplayer tic tac toe game
so thats why i wanted to disable the buttons for the other client when one player has its turn

[placid onyx]

Tictactoe game-state could be represented by NetworkList<byte> with 9 entries which are either 0 (empty), 1 (X) or 2 (O). 😉
Every client only needs to hook into OnValueChanged and update its game display, for something this simple you can even brute force it and destroy the board and recreate it every time it changes.

[lavish scaffold]

i actually had had a tic tac toe game
i was wondering if i could add online play into it
would ineed to change most of the variables so that they are network variables?

should i share it to show how i had handled it?

[dense cave]

And even then it's frustrating because each way to handle your network varies from dependencies lol like pun to mirror.

[sharp axle]

Adding multiplayer after the fact usually means rewriting a bunch if not all of your systems. For tic tac toe you really only need the one NetworkVariable/List. But it might be worth it to just start from scratch

[sharp axle]

Once you get the theory down the actual implementation of network variables and RPCs are just down to syntax. It's a lot like learning a new programming language

[dense cave]

Yup agreed. I'm just happy I don't have to worry about how they work and all that jazz. Lol I just hook it up and let them rip.

[spring void]

Since you're using [ServerRpc], it should work. 🤔 Did you have any other errors earlier? Have you started a server or hosted it? It's worth trying to log NetworkManager.Singleton.IsServer and NetworkManager.Singleton.IsHost.

[warped pilot]

No but maybe I found the problem. does the object need to be a NetworkBehaviour ?

ok this was the problem now all works fine

Hello. I am getting these error messages when i connect a client to a host in my game

is there a way to locate the network objects causing the problem or do i have to check every one to find a matching hash?

[placid onyx]

good question! so far I've simply checked each NetworkObject component since I don't have that many
NetworkObject shows the hash in the Inspector
worst case: make a script that gets all NetworkObject components in the scene and prints their hash and gameobject.name. It should also be possible to get all in-scene NetworkObject using Unity's Search feature.

That is correct. I normally will just give SOs an ID field and then I can reference them by id.

I got a sniper scope that uses a render texture prefab to give it that scope effect which works. however in multiplayer, if two or more players have the scope out, it only tracks the master clients. I know it's beacuse theres only one render texture but how can i make it so it makes its own render texture for each player?

[sharp axle]

You'll need to disable the other cameras that are rendering to that texture

[stiff ridge]

Possibly. 🙂

Fishnet question here.

Hey ive got a question. In my game, i have it so there can be player hosts. Think of it like a mini open world game, where different areas are different scenes.

The host and other clients are all capable of being in different scenes from each other. My network manager has a "scene condition" observer condition so that if the host is in a different scene than another player, they cannot interact with anything.

Items in my game are just a gameobject that calls OnTriggerEnter when a player collides with it, and inside that is a server RPC that adds it to the clients inventory.

The issue is that because of the SceneCondition, when the host leaves the current scene, players in the previous scene cannot pick up items anymore because its "not active". How can i work around this?

[split hedge]

Hey
I've got this gun positioning problem , the weapon, player has got a client network transform on it, and on the host, the positioning works, but on the client, (and on the host when the client picks the weapon up), it doesn't, the position doesnt update.

[visual hull]

Hello, how do you check from the client's perspective whether the netcode server is active and ready for our connection?

[fluid walrus]

it depends on what libraries and platforms you're using, this could be something you do through a lobby system

with NGO on its own i think the answer is just "try to connect and see if it works" 😛

[visual hull]

Only if I expect a faster response, I have to do my timeout / Stop Client if I do not receive a response to the data, e.g. ping pong?

[fluid walrus]

what are you using?

[sharp axle]

You would need some other intermediate server or service keeping track of the game server status

[split hedge]

bumper

[fluid walrus]

i'm not clear from your message, does the gun also have a network transform on it?

[split hedge]

yes

[fluid walrus]

can you see in the NetworkObject inspector if it's spawned on both ends and has the right owner ID showing up etc?

[split hedge]

It is spawned, but the position is off

[sharp axle]

If you parent it then you'll need to reset it's position

[split hedge]

Wdym parent it? It's not parented

It has a transform it follows

[sharp axle]

Its not following it very well it seems. Do you have an offset on it?

I'm using unity netcode and trying to set player's position by 500x and 500y here, however it works on Host side, and not on the client side. does anybody know the problem? i spent entire 4 days looking for the solution and couldnt find one.

            if (playerHp.Value <= 0)
            {
                playerDied.Value = true;
                originPos = transform.position;
                transform.position = new Vector2(500, 500);

        Vector3 knockbackDirection = direction.normalized;

        Vector3 knockbackForceVector = knockbackDirection * 10;

        // Apply the knockback force to the character controller's movement

What networking are you using? You will likely need to use an RPC to apply the knockback

You can try

        // playerVelocity.x = Mathf.Sqrt(jumpHeight * -3.0f * gravity);
        Vector3 knockbackDirection = direction.normalized;

        Vector3 knockbackForceVector = knockbackDirection * 10;

        // Apply the knockback force to the character controller's movement
        controller.Move(knockbackForceVector * Time.deltaTime);
    }

[vague geyser]

Very well, then you can try implementing this ClientRPC example i showed you

[slender lintel]

Thank you very much, looks like that kind of worked but the player that is getting the knockback is the wrong player.
i.e. A hit B, A gets the knockback(A pulled towards B) 🤦
What could be the cause?

I am guessing it got the wrong controller somehow?

[sharp axle]

You are calling knockback on the wrong player object. And sounds like you'll need to reverse the direction

[slender lintel]

sounds like it, but I have 0 idea how to call it on the right player object

currently it is called by ```

public void TakeDamage(int amount, Vector3 camDirection) {
    motor = GetComponent<PlayerMotor>();
    currentHealth -= amount;
    
    motor.knockback(camDirection);
    if(currentHealth <= 0) {
        Death();
    }

}

which didn't ask for which player object to call from

how do I tell it to call from the target instead of the attacker?

[nova linden]

heres a picture of the curve and it infact has 2 keyframes so it shouldnt be out of range, and it works perfectly unless i add script b to the same gameobject

Is there any reason for me to do server authoritative movement in a PvE co-op game? I'm making a small non-competitive co-op game where you can play in up to parties of 4. I'm having one client host and the other clients join that one person. Is there anything wrong with having client authoritative movement for each player? Obviously this could result in people cheating, but I'm not sure this is really an issue for my game?

i made this script to spawn different player characters for differnt levels so i dropped a empty gameobject in network manager's player prefab box and then attcahed this script to the empty game object so when the empty game object get spawn then the code run and it spawn the actual player character i want for that level

the spawn is working as it should but the client is unable to control the player and the host is controlling both spawned players which should not happen

[sharp axle]

You need to use SpawnAsPlayerObject() instead of Spawn(). And make that only the local player is accepting input

[flint grove]

can u update the script and send me back pls

i tried using SpawnAsPlayerObject() but its still same for me

im trying from hours now

[sharp axle]

That's really all you need to change. Make sure you are using a client network transform on the player prefab. Your input script should be checking for isOwner or IsLocalPlayer

I'm getting a couple weird errors only after I switch to one of my scenes from another one. when the scene loads I get "SpawnStateException: Object is already spawned" and then when I try to use the drag and drop UI in the scene I get "KeyNotFoundException: The given key 'InvintorySlot' was not present in the dictionary".

The drag and drop UI works by sending over indexes for the items and locally spawning the items on both clients to avoid reparenting, I think the intitalizing is what's causing the second error but I can't figure it out since it works when I test it as the starting scene. I'm using Unity NGO

[covert gull]

Should I use facepunch or steamworks.net for my co-op game that I plan to publish to steam? What is the difference between the two?

[opal dust]

Hi, just wondering if it's ok to post questions about netcode for entities in this channel or if I should ask in #1062393052863414313? My question is specifically about a server / client issue hence why I'm wondering if it's ok to ask here

[sharp axle]

The dots forum would probably get you a quicker answer. But here is fine too

[sharp axle]

There is no difference. They are just 2 different implementations of the Steamworks API

[lavish scaffold]

yeah right i think ill do that

Hello. Is it possible to implement a websocket server in unity to which one can connect via a javascript client in the browser? I found this example but I did not find a way to send data to the client: https://docs-multiplayer.unity3d.com/transport/current/minimal-workflow-ws/

https://docs-multiplayer.unity3d.com/transport/current/minimal-workflow-udp/

[livid nexus]

Should server rpcs never be called by the server itself, ie a playerhost?

[fluid walrus]

in NGO at least that's fine

[rancid vapor]

I would imagine you would need to go lower level than Transport, possibly importing a library like WebSocket-Sharp and using that if its compatible with the c# version Unity uses. The question is, why are you writing in unity for a js webclient? Would you not be better building a unity client for webgl, or writing the server in pure c#/nodejs?

[late gazelle]

I want to build a simulator in unity which sends position data over websocket to clients

[rancid vapor]

I'd be thinking of using a web socket library from nuget then

Im a noob tho 😂

[late gazelle]

Yeah seems the best option. I thought there might be a unity implementation already. Thanks

[hazy sonnet]

What could be the reason that my players don't spawn in a random position (and not at 0,0,0)? I'm thinking, is this a synchronization issue?

[unique gorge]

Hi, i am making multpilayer 5v5 shooter game. I want to use steam networking , but i am scared of DDoS. Is there something that can prevent DDoS?

[sharp axle]

Your server hosting provider should take care of that for you

[fluid walrus]

if you use steam you can use steam datagram relay which mitigates that like unity relay, since players' ip addresses aren't exposed to each other

[sharp axle]

If they are determined enough, they can ddos the relay server. Ultimately, there isn't really much you can do to prevent that type of attack.

[fluid walrus]

yeah, and it's gabe's problem to fix not yours in that case 😛

[split hedge]

Hello!I have this piece of code, where I'm applying force to a dropped weapon towards the player's forward direction.
On the host it works, but on the client, it does not, the playerCam.transform.forward is Vector3.zero
Why is this? Am I using the rpc wrong?

[unique gorge]

Thank you for answers@sharp axle @fluid walrus

[sharp axle]

Does the weapon have a client network transform on it?

[stable dust]

how would i go about instantiating a round system ? im using steamworks and mirror

[split hedge]

Yes the problem is not with the weapon
I debugged the playerCam.forward and on the client, its always 0,0,1
On the host it differs

[wanton forge]

[ClientRpc]
    public void TeleportPlayerClientRpc() {
        if (IsOwner) {
            GetComponent<ClientNetworkTransform>().Teleport(mapHandler.spawnLocation.position, Quaternion.Euler(0, 0, 0), transform.localScale);
        }
    }```

This runs but does not tp any player (the script is inside the player.)

[sharp axle]

Is the playerCam networked? You usually will have to disable the other cameras that are in the scene.

[sharp axle]

If you are not getting any console errors then the spawn Location position might not be getting set on the clients

[tame valley]

I'm testing network animations, and it appears to be the problem that others can see my animations but I can't see thiers

using Unity.Netcode;
using UnityEngine;

namespace DC.Input
{
    public class PlayerMovementController : NetworkBehaviour
    {
        [SerializeField] private float _speed;
        [SerializeField] private Transform _modelTransform;

        private CharacterController _characterController;
        private Animator _animator;


        private void Awake()
        {
            _characterController = GetComponent<CharacterController>();
            _animator = GetComponent<Animator>();
        }

        private void FixedUpdate()
        {
            if (!IsOwner) return;

            var horizontal = UnityEngine.Input.GetAxis("Horizontal");
            var vertical = UnityEngine.Input.GetAxis("Vertical");

            var move = transform.right * horizontal + transform.forward * vertical;
            if (move.magnitude > 1)
            {
                move.Normalize();
            }

            _characterController.Move(_speed * Time.deltaTime * move);

            _animator.SetFloat("Vertical", vertical);
            _animator.SetFloat("Horizontal", horizontal);
        }
    }
}

The gameobject that has Animator, has NetworkAnimator component added, the Host cannot see the animations of another client, but client can see the animations of host

[cunning quail]

I don't know if this is the correct place to ask this but, I'm thinking about delving into multiplayer for the first and I'm trying to figure out which framework to use. I just want make a simple lobby game with up to 8 players just walking around and interacting with each other. From what I understand, Unity has 2 solution, NGO and DOTS. What's really the difference between them? Which one should I start with? And will the NGO be replaced with replaced with new solution?

[austere yacht]

DOTS is not networking its a paradigm/toolstack. You should use NGO, no, it won’t be replaced by netcode for entities

[acoustic sapphire]

Just my 2 cents as a programmer:

What the difference is, is that Netcode for Gameobjects works for the 'normal' gameobject workflow in Unity. Also doesn't work on Entities.
Netcode for Entities as the name says, only works for entities. You need to use DOTS to be able to use it. This comes with a whole bunch of caveats, but the performance is amazing.
Starting with gameobjects is easier, because its also better supported by #archived-unity-gaming-services. You can simply drop in Relay & Matchmaking for example and it works. There are some examples on how to write this for DOTS, but this requires a lot of knowledge already. Using DOTS isn't something you just pickup, it's a choice you need to make if you really need performance. If you don't I suggest just sticking with Netcode for Gameobjects. Just 8 players should be fine with it.

[austere yacht]

Also, while entities is faster, NGO is by no means slow

[cunning quail]

I see, I'll start with NGO then, btw, I also saw some people suggesting custom solutions like fishnet, whats your opinion on that?

[austere yacht]

No netcode framework in existence is truly plug & play beyond trivial toy usage

[cunning quail]

I believe so, the game needs to be designed around the network

[austere yacht]

Use what has the most helpful community and is backed by a large enough corporation that won’t suddenly abandon the framework

(Never rely on stuff Google makes)

[cunning quail]

alright xD

thx for the help!

    public async void LeaveLobby()
    {
        m_GotKickedFromLobby = false;

        try

Hey when someone Leave my Lobby why does it not trigger my LobbyEvent ? If someone join it works fine ...

```        var callbacks = new LobbyEventCallbacks();
        callbacks.KickedFromLobby += OnKickedFromLobby;
        callbacks.LobbyChanged += OnLobbyChanged;```

[split hedge]

What do you mean networked? Like is there a client network transform on it?

[sharp axle]

You aren't getting a LobbyChanged event when a player leaves?

[sharp axle]

Yea. Does it have a Network Object?

[split hedge]

The player has, its under it

The cam has a client network transform on it tho

[sharp axle]

Is the camera disabled on those remote players?

[split hedge]

Go again please?

[warped pilot]

@sharp axle Yes I dont get the LobbyEvent when a Player leaves .. Joining is working fine

[sharp axle]

You said the Playercamera.Forward is always (0,0,1).

[split hedge]

Yes.
The camera is enabled

Its a cinemachine virtual cam if that helps tho

[sharp axle]

Sounds like you are getting the wrong transform then

[split hedge]

On host it works perfectly

[sharp axle]

So the clients are getting the wrong transform

[split hedge]

How is it? It would be the same

[sharp axle]

Are the other virtual cameras moving on the clients? Or is only their own camera moving?

[compact raft]

my clients connect fine and sync positions etc fine. But for some reason I can't seem to get this network variable to sync.

_netLookDir is always (0,0,0) on other clients

[sharp axle]

You have it set to readonly

[compact raft]

that's not how readonly works. Just means I can't change the networkvariable object, nothing to do with the value of networkvariable

[split hedge]

What would you classify as other virtual cameras? There is only one, a playerCam, and its moving, rotating (at least locally)

[lavish scaffold]

my code is working on the host side but not one the client side even though i am calling the client RPC and server RPC methods

private void Start()
    {
        game.SetActive(false);
        placeholderPanel.SetActive(false);

        NetworkManager.Singleton.OnClientConnectedCallback += (clientId) =>

            Debug.Log(clientId + " joined");
            if (NetworkManager.Singleton.IsHost && NetworkManager.Singleton.ConnectedClients.Count == 2)
            {
                Debug.Log("Game Start");
                StartGame();
            }
        };
    }
 private void StartGame()
    {
        StartGameServerRpc();
        StartGameClientRpc();
    }

[ServerRpc]
    private void StartGameServerRpc()
    {
        game.SetActive(true);
        networking.SetActive(false);
        Destroy(networking);
    }

    [ClientRpc]
    private void StartGameClientRpc()
    {
        game.SetActive(true);
        networking.SetActive(false);
        Destroy(networking);
    }

[fickle magnet]

I use [ServerRpc(RequireOwnership = false)] above [ServerRpc] so any player can call this method.
Then inside the ServerRpc method I call the ClientRpc.

Now, if this is to be a competitive online game my method is bad because you should ONLY have the host call the ServerRpc but for my game it's not competitive so this is fine.

[lavish scaffold]

i think ill try that
cause its not a competitive game
just a multiplyaer tictac toe

[fickle magnet]

    [ServerRpc(RequireOwnership = false)]
    public void SendWorldTextToPlayersServerRpc(int playerNumber, string info, string playerName)

        SendWorldTextToPlayersClientRpc(playerNumber, info, playerName);
    }
    [ClientRpc]
    private void SendWorldTextToPlayersClientRpc(int playerNumber, string info, string playerName)
    {
        if (IsPlayer(playerNumber)) { return; }

        Collector.gm.MultiplayerWorldChatText(info, playerName);
    }

example of what I do

This project was a huge leaerning experience and I know my code naming sucks and could be better now.

[lavish scaffold]

thanks i think ill try it
currently i was debuggin to see wether it is even calling the function or not

[fickle magnet]

The reason you call the client inside the server is cuz from the server it automatically sends to all the clients.

Unless anyone has a better way please share. I know my way works though.

[lavish scaffold]

ohh
so thats why it wasnt changing it in the client side

[sharp axle]

You are throwing a weapon in the direction of playerCam.forward, right. And on the clients where playerCam is not moving, the weapon is not going in the right direction

[unique gorge]

Is there some video tutorials for steam netowrking sockets?

[golden bone]

where do i begin with location sharing?

[mint anvil]

a quick question asking for advice: my game has planets each team can capture (1 start planet for each team) i want to have a list every player can see, which planets are owned by which team, but can i even make a networking list? or what would be the best solution (just rpc change the list? but then it can be out of sync?)

[sharp axle]

You could use either a NetworkList or use RPCs for this.

[rapid crater]

Is Unitys built in solution ready yet, or should i try to get parrelsync working?

[sharp axle]

If you are using 2023.1+ then Multiplayer Play Mode will work fine

[sacred schooner]

Hey I was wondering if anyone has any good learning resources for NGO? Not the absolute basics covered in CodeMonkey's or other's videos, but bite-sized examples how to do networking for more advanced systems? Or do you just reccommend digging through the Docs (lul) and chatGPT'ing your way around?

I eventually get things going but can't fully wrap my head around the Unity(TM) way of thinking around designing and implementing a system around multiplayer, which makes me waste a lot of time

[austere yacht]

chat gpt knows nothing about NGO

[sacred schooner]

It sure as hell pretends to do so then 😄

But it often leads to running in circles, hence the question

[austere yacht]

there is nothing special or quirky about NGO, it works like all other frameworks that have you write server & client in the same project

if you prefer you can skip all the abstractions and do it all via manual messaging and lots of boilerplate if that's your cup of tea.

typically a framework will only take care of the transport and connection/authority/message management for you with only very thin convenience components on top of that, so the first order of business is to have the right expectations.

[sacred schooner]

I'm fine with boilerplate to some extent (most of my CS courses are forcing Java ), was just wondering if you have some not-so-well-known resources that you found helpful when learning this shiiii

[austere yacht]

you'll get a new appreciation what "boilerplate" means when you try to do networking without a framework

[sacred schooner]

sure dude, but we are where we are, do you have something that answers my question?

[fluid walrus]

the official docs are fine, it's not a hugely complicated or powerful framework

[sharp axle]

CodeMoneky's complete multiplayer course is probably the best you are going to get.
The official docs are very good though. There are samples there beyond the getting started steps

If you really like the GPT interface then Unity Muse is trained on the official docs

[sacred schooner]

Yea I think I signed up for their AI package, but then they tried to take 80$ out of my wallet for a year subscription, opted out of that ASAP. Muse is free-to-use though?

[rapid crater]

no, muse is not free to use. all pricing should be posted.

[rapid crater]

Thanks!

[sacred schooner]

welp yeah so there goes that Muse guy out of the window. I thought there would be an easier way to do this, but to example projects and documentation i go!

I sent this message about help several times I wonder why noone replies to this. It's pretty important part in the whole multiplayer setup.

My question is:
What are the approaches of setting the values of MaxPayloadSize and MaxPacketQueueSize?

There can be 'n' number of clients connected in my session. How to determine the ideal value of these 2?

[waxen quest]

I already visited this link. Is this correct or any other approach is better?

i have made a network variable array of type <int> and then initialised them

but i am not able to synchronize data between the host and the client
when i click on either of the sides(host or client)
the buttons on the host side gets disabled but not on the client side

the cells is a network variable array of type int:

 public NetworkVariable<int>[] cells;

it is initialized in the awake function as :

cells = new NetworkVariable<int>[9];
InitializeNetworkList();

InitializeNetworkList() initializes each element of array and assigns defualt value:

private void InitializeNetworkList()
    {
        for(int i = 0; i < buttonList.Length; i++)
        {

            cells[i] = new NetworkVariable<int>(0);
        }
    }

whenever an update is made (ie a button is clicked) i am updating the array which is responsible for activing and deactivating the buttons

public void UpdateMade()
{
  Debug.Log("Update Made");
  UpdateButtonsServerRpc();
  UpdateButtonsClientRpc();
}

The UpdateButtonsServerRpc() method is as follows :

[ServerRpc (RequireOwnership = false)]
    private void UpdateButtonsServerRpc()
    {
        cells[3].Value = 1;//test values
        cells[7].Value = 1;
        cells[0].Value = 1;
        cells[5].Value = 1;

        for (int i = 0; i < buttonList.Length; i++)
        {
            if (cells[i].Value == 0)
            {
                buttonList[i].interactable = true;
            }
            else
            {
                buttonList[i].interactable = false;
            }
        }
    }

the UpdateButtonsClientRpc() method is as follows :

[ClientRpc]
    private void UpdateButtonsClientRpc()
    {
        for (int i = 0; i < buttonList.Length; i++)
        {
            if (cells[i].Value == 0)
            {
                buttonList[i].interactable = true;
            }
            else
            {
                buttonList[i].interactable = false;
            }
        }
    }```

its showing me this warning:

i have tried debugging it and added breakpoints but it isnt breaking when click the button

[fluid walrus]

i'm not sure NGO supports arrays of network variables, or at least i've never tried that 🤔 it scans for networkvariables in class definitions and does some hidden setup so you can't just instantiate networkvariables as normal objects

normally you'd use a NetworkList for this kind of thing i think?

[glass dew]

When the server receives a packet from a client, it will save it to the queue of that client's thread before processing it
Can I save the Action instead of the packet data so that the client thread can process it?
