[lavish scaffold]

i tried network lists but it gives me error for NullObjectReference
it alwas used to show me that error whenever i tried to
list.Add(0)

[waxen quest]

Make sure to initialize the network list in awake method. You can subscribe to onlist update event and get event when anything in list modified, added, removed, etc

 private NetworkList<int> playerDataNetworkList;

private void Awake()
{
    playerDataNetworkList = new NetworkList<int>();
}

[lavish scaffold]

yeah i had done that too

[waxen quest]

And only server or host can add or remove or update list not clienst

[lavish scaffold]

and i also tried to initiale it when i instantiated it

[waxen quest]

You deriving from NetworkBehaviour?

[lavish scaffold]

yeah i made sure that only host is updating it

[lavish scaffold]

deriving from network behaviori?

i do am using a network behavior component

[waxen quest]

The class should use this

public class PlayerDataHandler : NetworkBehaviour

Not MonoBehaviour

[lavish scaffold]

yeah i am implementng that too

[waxen quest]

and there should be component NetworkObject added in that gameobject

[lavish scaffold]

network object is also attached as component

[waxen quest]

ohh

[lavish scaffold]

currently i am not using that anymore
i am just using two seperate arrays which are being updated by one another

so thats not the problem

but i am encountering a stack overflow when i am updating the value of a variable

i have a playerside variable (which is local and not network)

i am selecting the starting side

from the host side

and then

calling clientRpcto update its value on the client side

[waxen quest]

Maybe the function calling itselft again and again causing stack overflow

btw you should come to new Rpc, the clientRpc and serverRpc is legacy now

[lavish scaffold]

i wasnt making something too big
it was just tic tac toe so i though i could use them
so i should only use Rpc keyword?

[waxen quest]

No no, refer to this link for details.

https://docs-multiplayer.unity3d.com/netcode/current/advanced-topics/message-system/rpc/

You can stick to server and client rpc if you want tho

[lavish scaffold]

yeah you were right

[lavish scaffold]

it was calling a function to update on the client side from the host side

and as host is also a client

it overloaded the function

[waxen quest]

Nice you found out

[crude peak]

how do i install netcode for entities 1.2

since unity package manager only allows 1.0.17

[empty quiver]

click the little plus top left of package manager and install by name

[lavish scaffold]

am just declaring a networklist of type integer and it is shows me this

line 14 is the one in which the integer list is being initialized

public NetworkList<int> integerList = new NetworkList<int>();

[sharp axle]

You can't initialize an NetworkList inline like that. It has to be in Start() or Awake()

[lavish scaffold]

so i need to instantiate it in the class and initialise it in the awake method?

[sharp axle]

Declare it globally there, yea.

[lavish scaffold]

ok let me try that

i am declraring the list in a network prefab
is that fine?

or should i declare it in some other class?

the prefab does have a network object and i am implementing monobehavior

[sharp axle]

It needs to be a networkbehavior. but otherwise thats fine

[lavish scaffold]

yeah it does have ClassName : NetworkBehavior
so thats fien right?

[sharp axle]

Yea. that's correct

[weak plinth]

I'm very new to networking...this is a very beginner question.

Let's say I'm using Unity relay to connect two players, and let's say player 1 shoots a laser, will the laser affect player 2? assuming that both player 1 and 2 have the same scripts for shooting lasers and taking damage from them?

[neat veldt]

No, you have to send a message of some sort, since player 2 has no idea that player 1 pressed the button

in this case most likely a RPC

[sharp axle]

Very generally, most of the game logic will be handled by the host. The host is the one who starts the match and is usually player 1. So what will happen is that player 1 will shoot player 2 then will tell player 2 that they just got shot. The other way around player 2 will tell player 1 that they pulled the trigger then player 1 will figure out if player 2 hit anything or was out of ammo or actually had died before he pulled the trigger. Then player 1 will tell player 2 what happened.

[rapid crater]

Is NGO not capable of server authoritative movement yet? I am being told to use ClientNetworkTransform. Do i just need to learn more, or is this a limitation of NGO at this point?

[remote relic]

If (IsServer){
Movement code
}

@rapid crater

You only attach the ClientNetworkTransform to an object you want the client to be able to move

[rapid crater]

Ok cool, i'll keep going then. Seems like they are saying to use client authority due to laggy movement. I would assume that is network settings, not an authority issue. cool deal, thanks

[remote relic]

Does your game need to have strict server authoritative movement?

[rapid crater]

my final game will, yes. a part of avoiding cheating

[remote relic]

Ok are you using a dedicated server or host?

[rapid crater]

the final game will use dedicated server. while learning, just using host usually. but, will attempt to test with dedicated, asap

[remote relic]

Yeah you will find what works best. If you need more help you can pm me. I can share stuff from my projects as they have, dgs, host, and client movement

[remote relic]

Also you can just have a separate build be the “server” and use (IsServer) instead of (IsHost) to test how a dedicated server would be

[rapid crater]

Cool deal, thanks. I am using ParrelSync ATM, since the built in solution (2023) does not seem to like my multi-monitor setup :/ I am still at the very basics though, so time will tell. I appreciate the offer 🙂 @remote relic

[sharp axle]

Lag is going to be something you will need to deal with one way or another

[rapid crater]

indeed. I think these tutorials are kind of saying 'use client auth' in the same way they say 'use public so it's accessible in editor' :/

[sharp axle]

There are some very neat changes coming to NGO soon that will help a ton in mitigating latency

[rapid crater]

Nice! in 6, or 2023? please don't say further down the road than 6. i'll have to use mirror or PUN in that case

[sharp axle]

Yea a 2 hour tutorial setting up a client prediction system just to move a capsule is not going to help anyone

[rapid crater]

2 hours and 35 minutes to be exact! 😄 samyams multiplayer tutorial

[sharp axle]

Distributed Authority is coming in NGO 1.9.0. It just got added to the docs this week. 2.0.0 seems to have some kind of client anticipation system

[weak plinth]

Oh...

[weak plinth]

Is there any tutorial of some sort for such a thing?

[weak plinth]

Let's say that player 1 spawns actual small bullets in game, and player 2 has a code that takes damage to such a game object in their script. Would it still need rpcs or stuff like that?

[arctic iris]

i can switch the lobby host when using the lobby system.
is there a way of switching the host of networkmanager so that when the host leaves the clients in the match don't get removed once host leaves.

[rapid crater]

it looks like UNet could do it, so there must be a way in the newer NGO
https://docs.unity3d.com/2021.1/Documentation/Manual/UNetHostMigration.html

https://forum.unity.com/threads/host-migration-solution.1248982/\

[sharp axle]

That is one way of doing it. But you really don't want to trust the client to apply damage to itself. Only the host can spawn objects so when player 2 shoots it would still need a message sent

[weak plinth]

Can I perhaps dm you if I encounter any problems?

[sharp axle]

I don't mind. But it's better post it here so everyone can learn

Or over on the Unity Netcode discord server

[weak plinth]

Oki

[arctic iris]

Thanks for this i will see what i can do.

[split hedge]

What do you think would be the cause of when the client drops an object using this server rpc, it remains in its hand SOMETIMES, but other times it just works. It looks like a coin flip.

[sharp axle]

Is weapon returning null when it fails?

[split hedge]

On pickup, it does

Sometimes!

It returns null, but also the weapon

What??

Btw, these debugs only run on the server

[molten hazel]

hi is there any code equivelant of
if (inside lobby)
//multiplayer stuff
else
//singleplayer stuff

[orchid mortar]

This will depend on the networking library that you're using, and on whether or not the library knows something like a "lobby". What library are you using? (Photon? Mirror? NetCode for GameObjects? NetCode for Entities? Something else?)

[molten hazel]

sorry, netcode for gameobjects, with relay and lobby

[lavish scaffold]

so network variables and list update in the next update for the client than they do for the host?

i am trying to make a tic tac toe game
i want it such that the host is able to select X or O to his will

i am able to achive that
but i am trying to implement is such that when its the turn for the host all the buttons are disabled for the client
and when its clients turn all the buttons are disabled for the host
till the next turn is made

the turns are stored in a networklist so if a grid has a value then the buttons corresponding to it is disabled and the text of it is applied to it

i have tried to update the server and client rpc

[sharp axle]

usually single player is just connecting yourself as a host.

[molten hazel]

haha, im aware, but im trying to not use lobby if i can for the release (to save money pretty much)

[molten hazel]

that being in the case of if the player chooses to play the single player mode

obv ill be using lobby when theres multiplayer involved

but kinda seems like a waste to me if there wont be any multiplayer involved

[sharp axle]

The alternative is duplicating all your code

[molten hazel]

huh

[molten hazel]

so no code exists like this

not even like
if (isOwner != null)
else

[sharp axle]

IsOwner will work only when the NetworkManager is connected. If there are no other clients then the host will own everything

[molten hazel]

so in that case would it return null if the network manager wasnt connected? sorry if im being dumb

[waxen quest]

Anyone?

[sharp axle]

it will always return false in that case

[sharp axle]

that forum post seems like the only solution to that

[waxen quest]

Ohh would have to go with it

[molten hazel]

coolio thank u for the help

[warped pilot]

Is the Networkmanager.Singleton.LocalClientId always 0 on the host ?

[neat veldt]

Yes, but I think it can be overriden by the transport you're using

(for unity transport it's 0)

[warped pilot]

I want save the clientId in LobbyData .. What is a good practice for that ?

I want make a Lobby Ready check .. Server side is working fine with Rpcs when all players are ready .. but i want make it visual so i need the clioentid of each player for my prefab .. and i think its best practice to save on connection the clientid in the lobbydata

and for the host i want use LobbyId = Networkmanager.Singleton.LocalClientId

[neat veldt]

I would just have a NetworkVariable/List which holds that information

You must already be sending the player names over to the clients?

or if the players have their own NetworkBehaviour, just a NetworkVariable<bool> should do

[warped pilot]

I use this for visuals ```
/// <summary>
/// Hier werden alle Spieler angezeigt die in der Lobby sind
/// </summary>
/// <param name="Lobby"></param>
///
public void PrintPlayers(Lobby Lobby)
{
foreach (Transform child in m_PlayerItemParent)
{
Destroy(child.gameObject);
}

    foreach (Player player in Lobby.Players)
    {
        PlayerItem playeritem = Instantiate(m_PlayerItemPrefab, m_PlayerItemParent);
        playeritem.Initialize(player, LobbyManager.Instance.IsPlayerItemHost(Lobby, player), LobbyManager.Instance.IsLobbyHost());
    }

    for (int i = 0; i < Lobby.AvailableSlots; i++)
    {
        Instantiate(m_EmptyPlayerItemPrefab, m_PlayerItemParent);
    }
}```

Then I setup my prefab on

    /// Hier wird dem LobbyPlayerItem die Werte hinzugefügt
    /// </summary>
    /// <param name="Player"></param>
    public void Initialize(Player Player, bool IsThisPlayerItemHost, bool LobbyHost)
    {
        m_PlayerName.text = Player.Data["PlayerName"].Value;
        m_HostIcon.SetActive(IsThisPlayerItemHost);
        m_PlayerId = Player.Id;

        if (!IsThisPlayerItemHost)
        {
            m_KickIcon.SetActive(LobbyHost);
        }

        ChangeColorPlayerItem();
    }```

[neat veldt]

Is Player.Data from Lobby? I'm not too familiar with it

[warped pilot]

yes

[neat veldt]

alr

[warped pilot]

I have already my function working but I dont know the clientid ^^

so i want set it up when I join / create a lobby

[neat veldt]

I'd send over some data the usual way with a NetworkVariable

[warped pilot]

so what is a good practice to save my client id in the lobby data ?

[neat veldt]

Again, not sure, but I don't think it's the best solution here

feels like you can handle it without the lobby system

[warped pilot]

Why does this not work ?

/// <summary>
/// Event wenn ein Client verbindet
/// </summary>
/// <param name="ClientId"></param>
private void NetworkManager_OnClientConntected(ulong ClientId)
{
    Debug.Write(ClientId);
}

because the host is a client too or ?

[neat veldt]

First off Debug.Write doesn't exist or is some other Debug, not the unity one

[sacred schooner]

Debug.Log or print should do just fine

[rapid crater]

I take back what i said. I am Not enjoying this tutorial. i am finding it a bit scatter-brained and out of order. also glossing over certain things. Some good foundational info though

[wet berry]

is photon pun outdated? i’ve been following a tutorial on it and don’t want to get too far into it with something not “useful”

[split hedge]

anyone could help?

[warped pilot]

Hey how could I update this Player ?

    /// PlayerData für die Lobby zum anzeigen
    /// </summary>
    /// <returns></returns>
    public Player GetPlayer()
    {
        return new Player
        {
            Data = new Dictionary<string, PlayerDataObject>
            {
                { "PlayerName", new PlayerDataObject(PlayerDataObject.VisibilityOptions.Member, AuthenticationService.Instance.PlayerInfo.Username) },
            }
        };
    }```

[simple spire]

Hi! Im trying to spawn in a player object across the network for my racing game, but no matter what I try, it seems to have some kind of race condition (ha.) somewhere that sometimes places the player at 0,0,0 rather than the position they're supposed to be. It's like a 50/50 chance, as far as I can tell. I haven't found the issue with debugging at all. I'm using Netcode for GameObjects for the networking.

I have a "race manager" object that manages the players in a race. Here is how the player is spawned from inside it, using Dreamteck splines for a racetrack:

private void HandleClientConnected(ulong clientId)
{
    // Get spawn position on spline
    SplineComputer trackSpline = track.GetComponent<SplineComputer>();
    SplineTrigger finishLine = trackSpline.triggerGroups[0].triggers[0];
    SplineSample finishLineSample = trackSpline.Evaluate(finishLine.position);
 
    // Create new ship and place it in the spawning position.
    GameObject newShip = Instantiate(playerPrefab);
    newShip.transform.position = finishLineSample.position;
    newShip.transform.rotation = finishLineSample.rotation;
    Debug.Log("Trying to set pos here!");

    // Subscribe player to spline position tracking
    newShip.GetComponent<SplineProjector>().spline = trackSpline;

    // Spawn player object across network.
    newShip.GetComponent<NetworkObject>().SpawnAsPlayerObject(clientId);

    // Lock it in place, for now.
    newShip.GetComponent<Ship>().isControlsLocked.Value = true;

    [...]

From this point, the ship's position isn't touched until its own fixedupdate call. Is anyone able to help?

[sharp axle]

You'll need to make sure that only the host/server is running this code. Clients can not Spawn objects. The ship's isControlsLocked net var needs to have server write permissions

[simple spire]

I do that earlier in a different function! Unless im missing something obvious here:

public override void OnNetworkSpawn()
{
    if (!IsServer) return;

    // Connect to track for lap recording
    track.finishLinePassed += OnFinishLinePassed;

    // Listen for new players joining    
    NetworkManager.Singleton.OnClientConnectedCallback += HandleClientConnected;
}

As for the control lock, it should only have server write permissions (in Ship.cs):

public NetworkVariable<bool> isControlsLocked = new NetworkVariable<bool>(false, NetworkVariableReadPermission.Everyone, NetworkVariableWritePermission.Server);

[sharp axle]

maybe subscribe to it in Start() If you are switching to this scene with the other clients connected then onNetworkSpawn might end up missing some clients randomly

[simple spire]

Gave that a try, but sadly it seems to not run at all in either Start or Awake :<
I think OnNetworkSpawn is working consistently, otherwise there wouldn't be a ship at all - the ship gets created in that function. It's just the position that has a 50/50 chance to be wrong

Would this be better in a thread? I should probably give more details-

[hazy sonnet]

I'm trying to get every client player's killcount* using Netcode for GameObjects. I tested this using a Host instance (client-server) and a Client instance, and this code seems to print the Client's killcount for both players. i checked that the Host and Client instances indeed have different networkKillCounts. what's the problem?

*Host and Client instances' players'

[sharp axle]

If this is on the player then it will just print the host's kill count twice. You would need to get the net var from the NetworkManager.Singleton.ConnectedClients[clientId].PlayerObject. Even then that will only set the _textstring of the host. The clients do not have access ConnectedClientsIds

[split hedge]

What do you think would be the cause of when the client drops an object using this server rpc, it remains in its hand SOMETIMES, but other times it just works. It looks like a coin flip.

[sharp axle]

No clue. Despawn() will always destroy the network object unless it's set with false then it will remain in the server only

[split hedge]

When I pickup the same object, sometimes the networkObject (weapon) is null.
Why do you think it could happen? And maybe I can fix it by saying: "You can only pick this up, if the weapon wouldn1t be null, if yes, spawn another in the same position which you can pickup" ?

[sharp axle]

That shouldn't be possible unless you are destroying the network object component itself somehow

[split hedge]

What you think I could do?

[dire rose]

anyone here works with photon ?

[loud bluff]

https://dontasktoask.com/

[dire rose]

[dire rose]

btw i fixed it thats why i didnt write a follow up, its was from my ridged body not synced through the photon

[loud bluff]

You should've written the full issue at the start.

[dire rose]

yeah, i wont do that after reading what you sent it made sense my bad. low skill in communication

[loud bluff]

That's alright, just fully explain the issue at once next time. Good luck! 🙂

[split hedge]

I finally got an error 'Null object reference' for line 135

So clearly the weapon is null, but how can it be?

Also its not null

But null

Ha?

[spare vault]

If I want to have people shooting bullets in my video game, would it be a better idea to have every bullet run their logic on the client or have each client be responsible for their own bullets and the bullets send their position and such over the internet

I think for special animations and particles and stuff it might be easier for all bullet logic to be done on each client but I’m worried about the performance.

[sharp axle]

It totally depends on your game. Are you firing 10 rounds a seconds traveling at realistic speeds? Or are they going to be visible so they can be evaded?
Worry about performance after you have the system you want working first

[sharp axle]

I don't know what line 135 says so I can't really help you there.

[wet berry]

are there any specific youtube tutorials you would recommend? sorry to be a bother.

[sharp axle]

No idea. I don't use Photon. Just try to find the most recent video and not the highest views. There are a lot of outdated videoes out there

[wet berry]

okay sounds good :D also another question, i'm pretty new to unity and I've gotten a grasp on how to use a lot of the features, and I want to make a multiplayer game. would you recommend implementing multiplayer early on and then getting all the features to work with multiplayer as I go, or the opposite, where I develop a lot of features and then get them working in multiplayer.

[sharp axle]

You need to design for multiplayer from the very beginning or else you'll be throwing everything out and redoing it

[wet berry]

thats what i thought, just making sure

thanks again :)

[spare vault]

some weapons will have different logic than others. some will just be raycasts because it's not worth doing anything fancy for high speed bullets and others will be slower projectiles. I think it's best to have all bullet logic on the client then, that way I can have more granular control on what happens to non-client bullets and client bullets

[junior flower]

Hey guys, I'm thinking of making some performance into my game to save bandwidth, I was wondering how to reduce from 32bit to 16bit when using vector3 and float, well it turns out it's there but I believe I need to add a few line of code to make this happen. Does anyone know how to convert it while using INetworkSerializable to synchronize the value to the server also to all clients across the network.

{
    public half Axis;
    public HalfVector3 Position;

    public void NetworkSerialize<T>(BufferSerializer<T> serializer) where T : IReaderWriter
    {
        if (serializer.IsWriter)
        {
            var writer = serializer.GetFastBufferWriter();
            writer.WriteValueSafe(Axis);
            writer.WriteValueSafe(Position);
        }
        else
        {
            var reader = serializer.GetFastBufferReader();
            reader.ReadValueSafe(out Axis);
            reader.ReadValueSafe(out Position);
        }
    }
}```

[sharp axle]

MIght use the BytePacker class.
https://docs.unity3d.com/Packages/com.unity.netcode.gameobjects@1.8/api/Unity.Netcode.BytePacker.html#Unity_Netcode_BytePacker_WriteValuePacked_Unity_Netcode_FastBufferWriter_UnityEngine_Vector3_
Otherwise I think you are looking at using some Custom Serialization
https://docs-multiplayer.unity3d.com/netcode/current/advanced-topics/custom-serialization/#for-networkvariable

[junior flower]

yeah i have look into custom serialization before but just dont really get it till now. Need some example of what people do on their code. 🤭

Hello, I'm following a tutorial for setting up photon fusion, and I'm completely lost.

this is the tutorial: https://doc.photonengine.com/fusion/current/tutorials/host-mode-basics/2-setting-up-a-scene

I've gotten up to the point "Creating a player avatar" but I'm not sure if I'm doing anything right. I have 16 errors in that one script and they are all telling me to add some interface member.

I already have a player controller and a player, but right now it's all going to shit because they are using unity 3d and I am not.

I can't find useful tutorials on youtube with fusion 2, and yet everyone is telling me to use the latest technology.

Could I have some guidance? I'm really passionate about game dev, just really new and am probably not doing it right.

Hello everyone, I'm new here. Right now I'm working on a project multiplayer game with netcode for game object and encounter problem to sync game object to all network client and host? I want to sync powerup Indicator when player picked up a powerup. I used server rpc but it doesn't work. anyone know what should I do?

[sharp axle]

You need to use a client RPC to tell the other clients about the powerup. Or you can use network variable

[desert gulch]

Prefab Powerup Indicator

the concept is when either host or client pickup the powerup, the powerup indicator will set active and follow the player

but i still dont understand the synchronization concept

when either host or client pickup the powerup,

You can use Connection Approval for this

yo guys.. quick question: Code Monkey has 2 tutorials for multiplayer 1 6hour long and 1 is 1 hour long are the 6 hours worth it? i have to learn enough to make a simple survival game.

[lavish scaffold]

i have a network prefab which has another prefab inside it
do i need to attach the network object component and make its script network behavior to the prefab that is inside the network prefab?

Hi Devs, I would like to make an online game where the game should call the server every 10 seconds to save player progress, my question is, would it be better to use a dedicated server or use unity cloud save + other unity tools?
Please provide pros and cons
Thanks for your help!

[lavish scaffold]

it calls a funtion in the gamecontroller (attached to the network prefab)
like there is fucntion UpdateMade()

it calls that funtions

and inside UpdateMade() i call a function named "UpdateButtonsRpc" which is sent to both client and host
so it indirectly calls a method in another scrict (which is a network behavior) and calls a local funtion which calls a funtion that is called on both host and client

[hearty dock]

To perform RPCs it will need to either be a NeworkObject or proxy the call through a NetworkObject.

Sup guys, im trying to experiment with the netcode for gameobjects package, but i cannot install the 2.0.0-exp 2 version, and i cant find it to install, any tips on how to find install this version?

[winged socket]

Hello there,
I want to make a server authoritative physic- based game. I'm thinking about using Netcode but I would like to know your opinion on this.
Cheers.

[storm sierra]

Anyone know how to use Server/clientRpc's?

[nimble drift]

is Netcode for Gameobjects expandable?
like can u build up on it
because im not sure which solution to pick

[sharp axle]

It's not released yet. You can grab the branch from GitHub if you want to go through the source code.

[sharp axle]

Networking physics will be a challenge no matter what framework you end up using

[sharp axle]

https://docs-multiplayer.unity3d.com/netcode/current/advanced-topics/message-system/rpc/

[sharp axle]

The source code is on GitHub, currently under the MIT License (soon to change to the Unity Companion License)

[nimble drift]

how can i use singleton instances when networking?

like here for example

thats what i did before

i know theres a way to do it with networking

[sharp axle]

You really don't want to use singletons in networking. Especially for players.

You might be able to get away with it for player input since there is only one local player

You would either need to use dependency injection or use events to hook up with your local network player

[nimble drift]

yeah i use singletons for most of my scripts

since it was a singleplayer game before

[wild mortar]

why specificially clients movement laggy? movement code: https://hastebin.com/share/fojapuxako.csharp

Anyone know why I can't move my camera sideways? It just rotates the cube though I'm rotating the player transform which has both the cube and the camera parented. It's also shaking for some reason. Already tried making it rotate the camera transform and had the same problem except it didn't rotate the cube.

[nimble drift]

Offline Transport (Single Player) Allows games to be played offline without the need of an internet connection.

im reading a networking solution comparison chart

[nimble drift]

and it says that fishnet pro has this, and mirror and netcode for gameobjects don’t

what does it mean?

like cant u make singleplayer and multiplayer without this?

[fluid walrus]

i haven't used fishnet but i think that's if you want to write your game logic using multiplayer features like RPCs and have it work in singleplayer too, useful if you don't want to have separate code for singleplayer and multiplayer

iirc you can still do it by hosting on 127.0.0.1 on the default transport, it's probably more efficient to have built in support though

[timber pebble]

are network variables still datatypes only?

[sharp axle]

value types. structs will have to implement INetworkSerializable

[timber pebble]

so i cant pass in a class or scriptable object or something

[sharp axle]

You can not

[timber pebble]

private void OnEnable()
        {
            NetworkPlayerInputController.markerStart += AddPlayerJoined;
            CharSelectMarker.ReadyConfirm += AddReady;
            CharSelectMarker.ReadyRemove += RemoveReady;
        }

        private void AddPlayerJoined(NetworkVariable<int> ID, NetworkPlayerInputController inputController)
        {
            AddPlayerRPC();
            inputController.ID = playersConnected;
        }
        
        [Rpc(SendTo.Server)]
        void AddPlayerRPC()
        {
            playersConnected.Value++;
        }

why isnt this working?

this is the on the network player input controller

figured it out, i think the player input controller is being created before the other one is a network component

how can i change this?

because the lobby is spawned before the player it wont run things properly

[timber pebble]

why isnt this working on the client?

public void MoveMarker(InputAction.CallbackContext ctx)
{
if (!IsOwner) {return;}
if (ctx.performed)
{
markerMove = ctx.ReadValue<Vector2>();
print(ID.Value + " Move marker: " + markerMove);
}
else
{
markerMove = Vector2.zero;
}
}
it works fine on the host, but on the client it breaks
or just doesnt work at all

[nimble drift]

why cant i delete this?

as soon as i delete it a new one is made

cause i have another one already

[sharp axle]

its in the project settings to automatically create a default network prefab list

[nimble drift]

where

[nimble drift]

is it this?

[sharp axle]

oh no clue about fishnet, but looks like thats it

[timber pebble]

are these okay to use in networking?

[mild magnet]

Hey

I wanted to ask does photon work well with steam? I plan to make a peer to peer fps game and want to know if it is compatible

[nimble drift]

so i have a rigidbody movement system
im not sure what network components to put onto it

as u can see it looks good when other players move
but not when u move
the camera like jitters

[harsh glade]

Is the camera parented to the player in some way?

[nimble drift]

no

[nimble drift]

its a networking issue because when i remove the NetworkTransform and OfflineRigidbody it doesnt jitter

https://hastebin.skyra.pw/adabijoyay.csharp

[sharp axle]

Where is the camera getting set of it's not part of the prefab?

[nimble drift]

what do you mean

[sharp axle]

If the camera is not part of the player prefab then when the player spawns it will not have a reference to the camera.

[nimble drift]

no the camera its inside of the prefab

    Movement - (Movement script with rigidbody, collider etc)
    Camera Holder
        Camera ```

Player is the prefab

Hello everyone,
I want to do some load tests on the megacity metro sample. For this, I intend to create thin clients outside the editor, which is possible with the -enable-thin-clients parameter. But they do just try to connect to matchmaking in the megacity metro example.
Does anyone know how and where to change the behavior of the thin clients in megacity metro? I've made it work that the first thin client correctly connects to my local server, but the others fail to do anything.

Furthermore, is there any documentation on ThinClients? I wasn't able to find any.

[austere yacht]

Your only practical option is to flag all server code with #if SERVER (define depends on the framework you’re using) and compile it out of the clients that way

a common practice to simplify that is to always have a -server/-client/-shared triple for all network related classes

those can also be partial classes which simplifies the encapsulation

[rotund night]

Unity actually implemented ThinClients for ECS with the PlayMode Tools. The only problem is that (as with everything Netcode for Entities related) they are documented very poorly.

[austere yacht]

Suppose that depends on your definition and context what ‘thin’ means

[rotund night]

Unitys ThinClients can be made as thin as you want ...

[sharp axle]

Ask the folks over on #1062393052863414313 I've only been able to use thin clients through the editor

[rotund night]

I've got it to work! Seems like megacity metro already had a system for this, but someone commented it out (for whatever reason...)
Thank you for your halp evilotaku!!

[sharp axle]

Nice! Where exactly is it? I glanced around the repo a bit but couldn't really find it

[rotund night]

https://github.com/Unity-Technologies/megacity-metro/blob/master/Assets/Scripts/Gameplay/Client/Netcode/ThinClientAutoConnectSystem.cs
To use this you would have to create thinclients in the player with the parameter "--enable-thin-clients <amoung>".
If used in headless mode this will trigger the matchmaking flow in the megacity metro sample, but if used without headless mode the thin clients will follow the main clients connection. It would be great if you could just specify a network address and port the thin clients should connect to, but I think I'll have to implement that myself

how can i make sure other players see the weapons

this is a weapon switching script

im using fishnet

im trying something like this

the ObserversRpc is a ClientRpc right?

just fishnet has a different name for it

alright i've got this now

https://hastebin.skyra.pw/janocazimi.csharp

but there are two problems

when i press a key to change a weapon

theres a delay for the owner

and also lets say i have a weapon equipped

and another player joins

he cant see that im already holding a weapon

[strange jungle]

you can fix that by doing BufferLast = true in the observersrpc

Hello everyone. I'm making a multiplayer air hockey game on Unity with NGO and Relay. I'm having trouble getting the yellow puck to spawn once and share it's position across the host and client.

[vestal meadow]

Hello, please advise what is the best way to implement multiplayer, if I want to implement a game in which the game state will be stored on the server, are there any tools?

[loud echo]

does unity have free servers or will i need my own

[hazy sonnet]

sorry for the late reply, this is code in the player that's run server-side. why shouldn't it have access to ConnectedClientsIds?

[sharp axle]

If its only running on the server then only the _texstring and _placement variables on the server will get monified

[sharp axle]

If you are using dedicated servers then you will have to provide your own. You can use the Relay Service which doesn't use servers but has a free tier

[loud echo]

idk im just tryna make a pvp game

[hazy sonnet]

how would i get the networkKillCount.Value of each client?

[sharp axle]

loop through all the clients and get their playerobject with NetworkManager.Singleton.ConnectedClients[clientId].PlayerObject; Then you can get whatever component has networkKillCount on it

[hazy sonnet]

can i loop through them like this?

foreach (var clientId in Networkmanager.Singleton.ConnectedClientsIds)
{
NetworkManager.Singleton.ConnectedClients[clientId].PlayerObject
}

like this

[sharp axle]

Yea. that should work

[opal night]

I've never used networking with Unity before and have a quick question. When you enable a gameobject for use with some type of networking component, netcode, mirror, etc, do all the properties of the object get syncronized with all players or is it only certain ones?

I ask because what if I had to stream some instructions in to a textmeshpro textbox, would every client also see those changes as they're being updated in the textbox?

[austere yacht]

Nothing gets synchronized automatically

There are a few helper components that make it somewhat automatic to sync transforms and other basic stuff but generally, whatever you want to sync, you gotta do it manually and explicitly.

Some frameworks try to sync „everything“ automatically, but those don’t scale and fall short very quickly

[opal night]

ahh nice, which ones do it automatically? is that Mirror / Photon ?

[austere yacht]

None of the ones you mentioned or any of the ones that are fit for recommendation

[dry maple]

This is not about Unity.

You only want to sync what's vital to the game to function properly.

Bandwidth is not free, it's a limited resource. You should only sync what you need otherwise you would be paying more than you should. Not to mention performance impact of having to sync everything.

[muted garden]

using UnityEngine;
using UnityEngine.Networking;

public class PlayerController : NetworkBehaviour
{
    public float speed = 5.0f;

    // Update is called once per frame
    void Update()
    {
        // Only allow control if this is the local player's object
        if (!isLocalPlayer)
        {
            return;
        }

        // Handle player movement
        float moveHorizontal = Input.GetAxis("Horizontal");
        float moveVertical = Input.GetAxis("Vertical");
        Vector3 movement = new Vector3(moveHorizontal, 0.0f, moveVertical);
        transform.position = transform.position + movement * speed * Time.deltaTime;
    }

    public override void OnStartLocalPlayer()
    {
        // You can use this function to do things like change the player's color
        // to indicate which object they control
        GetComponent<MeshRenderer>().material.color = Color.blue;
    }
}

was playing around with AI co-pilot tryna see its capabilities, I ask it to make movement for a top-down 2D game, does the code check out?

[opal night]

ok, i'll give Mirror a shot first. I'm not concerned with bandwidth or performance at the moment. I'm just looking for whatever is easiest at the moment.

[dry maple]

What is your game? Is it player-hosted or dedicated-server? Or just learning networking.

[opal night]

Learning only. Theres no users other than me. I was just curious about learning whats involved in spining up a dedicated server and connecting to it. I might try to make a little chat app first.

[dry maple]

Chat app? No. Most of what is involved in that has nothing unique with gamedev. And it's also just msg passing.

Do a simple FPS where you spawn players around a small environment. Maybe add shooting too.

That will teach you a lot of the basics.

[opal night]

Eventually I might get there, right now I'm only interested in "Chat". If you want to think of it in terns of gamedev, think of it as talking with an npc.

I think I'm all set, i dont have any other questions. Gonna give mirror a shot first.

[dry maple]

Good luck!

[opal night]

thx!

[fringe imp]

Hey everyone! Hope youre having a good day,

Im having an issue with serverRPCs and ClientRPCs, With this code oprovided i shoot on the host and it shows up on the client too, but if i shoot from the client, nothing happens.

Code here - https://gdl.space/ubulemowob.cs

[fringe imp]

😭

[strange jungle]

youre trying to spawn the bullet on the client when you should be spawning the bullet on the server

[fringe imp]

Hey thanks! And even if i want the game to be client authoritive?

[fringe imp]

am i spawning on the client when i do the serverRPC?

[strange jungle]

in the function Shoot which is called on the client you're doing currentBullet.GetComponent<NetworkObject>().Spawn(true); and you can only spawn objects on the server, so id say spawn the object on the server and do all the calculations on the server

[fringe imp]

when i change the Serverpc method to call just Shoot(); Then i dont know how to get the client to be able to do it too i guess maybe thats where im stuck and confused?

[strange jungle]

ok, you have two options for synchronizing the bullet to clients, either have a networktransform on the bullet or you can have the client fire the bullet locally, basically duplicating the server's actions

[fringe imp]

from documentation i read serverrpc will be fire from client executed on server, but it doesnt do anything, on the bullet i do have a ClientNetworkTransform, Maybe that NEEDS to be a regular NEtwork Transform instead?

also thanks so much for helping

[strange jungle]

im not sure, i use fishnet which doesnt haven clientnetworktransform, only networktransform, but you can try the networktransform

but using networktransforms for every bullet might use up a lot of bandwidth so the better method may be to just shoot the bullet locally AND on the server, but that might have desync issues

[fringe imp]

ah i see, ok thanks so much!

[strange jungle]

i've never done this method before so i dont really know but i think a possible solution to better sync up projectiles would be to first, fire the bullet on the client, then fire it on the server, then the server sends back information ONCE about the position and velocity of the bullet in order to fix any possible desync

[fringe imp]

@strange jungle so maybe something like this?

 if (isAutoFire)
 {
     if (Input.GetMouseButton(0) && currentAmmo > 0 && Time.time >= nextTimeToFire)
     {
        

         ShootServerRPC();

         if (!IsServer)
         {
             Shoot();
         }
         

     }
 }

in regards to if youre just a client just shoot locally?

[fringe imp]

thats a great idea ok cool i will try that out'

So that code i just sent almost everything works now just need to get the bullets to show up from client to other clients. Almost there i think, thanks again ill figure it out!

[warped pilot]

As client I get this error: NotServerException: ConnectedClientIds should only be accessed on server.
Can someone help me there ?

[fluid walrus]

ngo is right, only the server has this information, so get the client to ask the server to do this via rpc instead

[sharp axle]

this needs to be a NetworkBehavior. and you need to make sure that SpawnVehicle() is only being called on the server

[warped pilot]

{
    [SerializeField] private Transform[] m_Vehicle;

    public override void OnNetworkSpawn()
    {
        if (IsServer)
        {
            NetworkManager.Singleton.SceneManager.OnLoadEventCompleted += SpawnVehicle;
        }
    }

    /// <summary>
    /// Hier wird der Spieler gespawnt
    /// </summary>
    /// <param name="sceneName"></param>
    /// <param name="loadSceneMode"></param>
    /// <param name="clientsCompleted"></param>
    /// <param name="clientsTimedOut"></param>
    private void SpawnVehicle(string sceneName, LoadSceneMode loadSceneMode, List<ulong> clientsCompleted, List<ulong> clientsTimedOut)
    {
        foreach (ulong clientId in NetworkManager.Singleton.ConnectedClientsIds)
        {
            Transform playerTransform = Instantiate(m_Vehicle[ClientSingleton.MyInstance.MySelectedCarIndex]);
            playerTransform.GetComponent<NetworkObject>().SpawnAsPlayerObject(clientId, true);
        }
    }
}```

I have changed it

and it is working fine thanks a lot

Networking is still hard for me ..

[warped pilot]

One more question! Im saving the Index of the car to spawn in my CarSelector script! In the next scene I spawn the vehicles! But all players have the same car like the host. what do i false ?

[fluid walrus]

i'm guessing you should add a parameter to VehicleSelectReadyCheckRpc so the client sends which car is selected, rather than using m_CurrentCar, which probably isn't set on the server?

[warped pilot]

ok i give it a try

ok now it is working correctly

[neon rampart]

Any solution?

[fluid walrus]

CORS headers are for the server, not the client, you can't set them on your unity requests

[rain olive]

I ended up running it through https://corsproxy.io, however I did get forbidden errors when using it in the editor.. On web it works fine

[neon rampart]

I've also included a hardcored set of headers, from the official docs (the heads with a bunch of ALLOWEDs and underscores) , just to test it out, but the request doesn't even reach my server. My server runs locally

[fluid walrus]

where are you setting the headers?

[neon rampart]

I read online that using a proxy is overkill and there's no guarantee for it's responsiveness

[neon rampart]

To every response from the server, for testing out. It's a simple c# server, using HttpContextResponse.AddHeaders

I should also note that the server works fine

[fluid walrus]

hmm what's the error you get in the browser?

[neon rampart]

For non webgl clients

[rain olive]

🤷‍♂️ on the unity forum I got told there was little I could do except for using a proxy

[neon rampart]

I see the preflight failure mark in the Network tab of dev tools in Edge. As for the error log itself, it's similar to this one

(I'd remove the embedded image from the link but I'm on mobile)

[fluid walrus]

next thing to check would be that you can see the CORS headers being sent in response to the preflight request as you'd expect

oh wait are you accessing the server via localhost? last time i checked you had to run the browser with security stuff disabled for that to work

[neon rampart]

Yeah but i see absolutely no request in my local server...

[fluid walrus]

yeah, it's a browser feature

in chrome it should work if you run chrome with the --disable-web-security command line option

[neon rampart]

Fortunately my server module is open source so i can share it.
https://github.com/somedeveloper00/HttpListener/blob/f1e4aac2bc2ce9faead40476ed49018de9ef6862/HttpServerComponent.cs#L173
The highlighted line is where I add the headers hardcoded. I don't expect you to read everything in there of course

Point is that it uses standard libraries from C#

So if there were any requests, it should've caught them

[fluid walrus]

yes, it's a browser feature so the browser will refuse to send requests if the CORS doesn't check out

which it won't on localhost

[neon rampart]

So okay lets ignore my implementation for a moment. Conceptually, in my 2nd server, I should expect an OPTIONS request, and I should respond to that with the standard CORS headers, and then expect the actual POST request later. Is that right?

[fluid walrus]

yup

[neon rampart]

I'm asking to make sure that I've got the concept right

[fluid walrus]

you can see it happening on pretty much any webpage out there these days, check the console and click around a bit and you'll see preflight requests all over the place

it's required for anything dynamic that isn't just loading a resource iirc

[neon rampart]

@fluid walrus thanks, and sorry for the last few weird messages, they were supposed to come one after the other but my internet was really slow. Just got your response

[unkempt glade]

dose any one know too too make a part of my player model invisble too the owner but not too other players im using Photon

[haughty heart]

You presumably know how to check if the player is the owner or not, so assuming that, have a check that disables the mesh renderer of the player model for the owner.

[unkempt glade]

im new so i have no clue how too

[haughty heart]

Well, ignoring the fact a beginner should not attempt networking (since beginners are deaf to that advice), you need to find a tutorial for photon that covers the basics with special attention to learning how to determine the authority of an object.

Once you actually know how, then you can worry about hiding the model.

[noble flower]

Yo guys quick question. Is Mirror a LAN or WAN

[oak flower]

What would be a point of lan only framework. Mirror also supports several punch-through frameworks as well for p2p connection.

[neon rampart]

I fixed it in the end, just 10 lines of code. im very surprized a lot of web results suggested to install a whole bunch of modules or use a complex proxy for 10 lines of code...

if anyone in the future wanted to know how, my solution is open source, at this permalink

[rain olive]

🤷‍♂️ the proxy wasn't that complex, you just had to add the link before the website you wanted to access and it would do it for you

[neon rampart]

it's a dependency

if you don't mind, it's alright. but for some cases, dependencies are not desirable

[warped pilot]

Hey I trying to make StartPositions (its a racing game) my list is working correctly .. i have the problem when I join with 3 players or more players join on the same spawnposition. maybe u can find the problem here:

Not sure if this belongs here but:

Sry for it being an image, just copied it from another place where I asked

[warped pilot]

In Editor it works fine. When I build it in Fullscreen it doesnt work .. Player get spawned not at the spawnpoint. Maybe someone see the problem here ?

In build only the first one. I have 8 Spawnpoints for my vehicles. I want that every player spawns on a different spawnpoint but only if 4 players are playing then spawnpoint 0-4

if 6 players are playing then 0-5

but on mixed positions

not the first one on 0

Hello, I just wanted to ask...

Im using Photon 2D and the movements and others is synchronized but when it comes to my character (sprite) that have bones its not updating on different devices

[brisk chasm]

what is some good networking solutions for unity right now? i looking for something that both support p2p and server client connection. i was debating to make my own from the bottom as i think it would be a good experience but that isnt what i am focused on right now. any ideas?

[main bloom]

Im using mirror but there is alot of different ones

Fishnet is another one ive heard

But mirror is a really nice open source one with very helpful devs and community

[brisk chasm]

yea i looked into mirror but i didnt find alot documentation about p2p

[main bloom]

what do you mean?

[brisk chasm]

peer 2 peer

[main bloom]

yeah I know but how did you not find anything i wonder

I never did any multiplayer/ networking in my life and I somehow managed to get my game working in multplayer + steam integration and lobbies. I dont know much about other solutions so I am not sure I am a big help

But my experience with mirror was very nice, and for p2p it has a ton of transports that you can use

[brisk chasm]

do you have a link to the p2p docs?

[main bloom]

https://mirror-networking.gitbook.io/docs/manual/transports/fizzysteamworks-transport

well this is just the one I use

not sure if mirror has their own transports

There is a few in the list on there

This is the ones that come with mirror

[brisk chasm]

alright thanks ill check it out

[main bloom]

This one I use does not come with mirror but is the most used solution for steam i think

If you have questions you should ask on the mirror discord, they are very helpful there

[brisk chasm]

alright thanks

Whats the problem here ? On fullbuild when I join my player gets spawned not on the spawnpoint. But in editor it works fine ..
I have an array with 8 spawnpoints. I just wanted test it with 0 to find the problem.

Both Debug.Log give the correct position. But sometimes the player spawns on 0.0.0! can someone help me there ?

[blissful jay]

there is literally only one solution with what you want, which is Photon Fusion (PUN too, but that one is outdated)

Mirror and all the alike don't support p2p at all. they are just client-server netcodes fully

[blissful jay]

hey, you don't look you have any experience with this. P2P is not what you think it is

p2p is not a "transport", it's a whole different paradigm of game networking

[main bloom]

I know

I told him there is a variety of transports for p2p

[blissful jay]

p2p has nothing to do with transports

it's a complete different paradigm of game networking

unsupported by mirror

[main bloom]

What???

[blissful jay]

yes, mirror is client-server only

it does have client auth, but that is a different thing

p2p is when you are physically connected to other players in the game, direct tcp/udp connections, which sometimes can be relayed

mirror does not support that

[main bloom]

Cool

Good to know I guess xD

Told you I dont have any experience and never did any networking

[cosmic veldt]

Probably a silly question but when using a ServerRpc, specifically the netcode for gameobjects implimentation. If a client decompiled, modified the instructions inside of a serverrpc and then recompiled. Would that client then be able to run custom code on the server or does it run the implementation that the server has?

[blissful jay]

yes, VERY SILLY question

like did you somehow think that the client is going to send the rpc instructions with every sent rpc and the server is going to naively execute them?

😂

it would be the easiest job in the world to do remote code execution and do huge damage so easily

[cosmic veldt]

Yeah lol. Just getting exposed to netcode. I just wanted to make sure I wasn't creating a massive security problem xD

[sharp axle]

There is no such thing as a silly question. But to add on, the only data sent in RPCs are the arguments of the function. Rule #0 of networking is to never trust the client. You should always sanity check any data received because you never know what bad actors might be trying

[river gazelle]

Would something like this work to prevent cheating in my game?
It's an idle game build in Unity, the server is a C# Cloud Code Module (UGS) and the database is MySQL on Google Cloud
CCM server is not persistent, so it loses all data and stops execution immediately upon a return statement

1. Player logs in

2. Client requests a random seed from server

3. Server generates a random seed, saves it to the database, sends it back to the client

4. Player clicks “Adventure”

5. Client immediately starts adventure using the random seed received in step 3

6. After each important event, the client sends a notification to the server

7. The server re-calculates all combat and rewards up to then, with the random seed to check if everything is still ok

8. Server saves everything to database and generates a new random seed, saves it to the database and sends it back to the client

9. After the next important event, the client starts using the new seed

10. Repeat from 6

An important event could be like every time an item is dropped or a boss is killed, and automatically after every 10 seconds or so?

It's pretty hard to explain the whole concept here, feel free to ask questions!

[main bloom]

Does someone have experience with steamworks stats?

[cedar garnet]

Hello everybody! I would like to make a rogue style game that allows for networked multiplayer for up to 4 people per game to play together. I know that recently Unity reworked it's networking system and I don't know much at all about network programming. What Unity networking solution would I need to look into working with? Also, can players be in separate scenes in multiplayer as well (like one died and is back in town, while the other is still alive fighting through a dungeon)?

[sharp axle]

Netcode for Gameobjects should work fine for most of that. the custom scene management is a bit more complicated

[cedar garnet]

Well I definitely don't want to overcomplicate it. Maybe what I could do then is if a player dies they hang out in a view watching the other players until those players reach a kind of "checkpoint" which revives all dead players.

[dreamy condor]

Hello, I'm creating a system to connect a database to Unity (from a server). I'm using PHP on the website to do it, and I already have HTTPS. But I have one important question: is this secure? I mean, can someone just connect to this site and grab information? If yes, then are there any ways to make it secure?

[sharp axle]

Its as secure as your php code. the website and DB especially should not be publicly available. It would be worth it to pay a hosting provider to deal with that aspect

[dreamy condor]

Thanks, but what if it's planned to have the game downloaded, and i need to connect into it?

[sharp axle]

The database should really only be connected to by the game server.

client side prediction maybe

[sharp axle]

Networking physics is some of the hardest things you can do.
A client anticipation system was just released in 1.9.1 but it's almost entirely undocumented currently
https://github.com/Unity-Technologies/com.unity.netcode.gameobjects/releases/tag/ngo/1.9.1

The API docs have a bit more information but not by much
https://docs.unity3d.com/Packages/com.unity.netcode.gameobjects@1.9/api/Unity.Netcode.Components.AnticipatedNetworkTransform.html

There is also an experimental sample that seems to use an older version
https://github.com/Unity-Technologies/com.unity.multiplayer.samples.bitesize/tree/main/Experimental/Anticipation Sample

[spring galleon]

Thanks for the help 😁

I'll try it out if I can

But I'm on a tight deadline. What if I create a doll of the client on the server/host and have that follow the client around. So the doll would have the same physics set up and act like the client but exist on the server/host?

[sharp axle]

Yea. That's basically the concept of the ghost object. You just have to make sure that you are resimulating physics for the local client. Unity physics is non-deterministic so it's possible that the client and server might still get out of sync occasionally

[spring galleon]

😩

[nimble drift]

how can i delete the lobby?

because at the moment when i leave the lobby

and i was the host

i can still join it with the old id

and at that point the lobby shouldnt exist

[main bloom]

steam lobbies should get automatically 'destroyed' when everyone leaves

[nimble drift]

they dont

apperantly

after everyone leaves

including my self

i can still join with the old code

[main bloom]

I just checked and I do the exact same that you do

It works for me

you sure the CurrentLobbyID you use to leave is correct?

[nimble drift]

yeah

[main bloom]

Im doing the same

[nimble drift]

could u try and record a video

to show me that its working

the same problem

i just wanna make sure im not tripping

its alright if u dont want to

[main bloom]

how would I even show that its not open anymore

I have my own custom lobby List, I can show you how old lobbies I created dont show up there after I leave I guess?

but not sure how that would help you

[nimble drift]

alright dont worry

wait i got a video

i can show u

i think

because im not in my house rn

this is what i mean

i host a lobby

copy the id

exit the lobby (which should destroy it)

and then i try to join with the id

[main bloom]

how do you join/ create the lobby

You sure its the same lobby and not a newly created one?

im making a tag game and have 2 players in a scene i want to set up a round system where if the players collide or a timer runs out the round resets and the players swap roles and a point is added to the right player im using mirror and was wondering how to go about making this

Hey maybe someone here can help me.

        }
    }


    private void OnSceneLoaded(string sceneName, LoadSceneMode loadSceneMode, List<ulong> clientsCompleted, List<ulong> clientsTimedOut)
    {
        SpawnVehicle(clientsCompleted);
    } 

   private void SpawnVehicle(List<ulong> ClientsCompleted)
    {
        foreach (ulong clientId in ClientsCompleted)
        {
            if (HostSingleton.MyInstance.MyPlayerVehicleDictionary.ContainsKey(clientId))
            {
                int carIndex = HostSingleton.MyInstance.MyPlayerVehicleDictionary[clientId];

                Transform playerTransform = Instantiate(m_Vehicle[carIndex]);
                playerTransform.position = m_StartPositions[m_StartPosition.Value].position;
                playerTransform.GetComponent<NetworkObject>().SpawnAsPlayerObject(clientId, true);
                m_StartPosition.Value++;
            }
        }
    }```

Here I spawn my player. Each variable is working fine. But sometimes the player got spawned on 0.0.0 on the map.

[twilit ingot]

try setting the position after calling SpawnAsPlayerObject?

[magic mirage]

Unity.Netcode.NetworkSceneManager.SceneHashFromNameOrPath (System.String sceneNameOrPath)```

I get this error when I make unity editor host and visionOS or simulator client. If I run simulator or vision as host and connect with either one it works fine without errors.

I'm not loading any other scene dynamically or anything, the game is a single scene thing. The network manager has 'enable scene management' on beause it would complain about the networkObject inscene otherwise.

Anyone has an idea?

[warped pilot]

I have tried it. Doesnt work either. But I found the problem its something in my vehicle scripts. now i have to figure out witch is the problem.

[round ether]

what happens if im using 2022

[sharp axle]

Then you would need to use ParellSync

[round ether]

yup i have it working now! thanks

[round ether]

only issue everytime i add something new do i make a new clone

or can i like update the old clone?

[sharp axle]

I was pretty sure the clone would update automatically. Do you happen to have Domain reload turned off?

[round ether]

How do I check 😭

[sharp axle]

https://docs.unity3d.com/Manual/DomainReloading.html

[round ether]

so i turn it on?

[sharp axle]

Yea give that a try

[round ether]

thanks! ill try rn

no didnt work i even tried creating a new clone and its same as old one

Hi everyone, I'm building a 2 player turn-based tower defense game in Unity and I'm looking for the right networking solution. I've started using Socket.IO, is it the best solution for my situation?

Here's a breakdown of what I have:

Game Description:
Players take turns placing towers and enemies on a defined map with pre-set paths.
After a set of turns, the simulation begins (enemies start to move in their corresponding paths)
Then the roles switches and defender becomes the attacker and other way around.
The game is decided by whoever tanked the most enemies.

Need to sync the game state after each turn, including:
Tower positions and types
Enemy signed paths
Current player turn

Also:
Enemy positions and health
Tanked Enemies,
Tower targeting system (in simulation part)

I know it is quite complex to integrate a multiplayer, that's why i'm asking for any recommendations or tips.
Thanks a lot!

[bronze tendon]

hey im havong trouble with unity's netcode. i made it work last week, and suddenly it doesn't work anymore. the players can join a lobby, and the relay, but then the transform for other players is not updating. i tried rewatching the tutorial i followed (CodeMonkey), but somehow it's not working anymore. i checked everything multiple times, rewrote the script, started from the beginning again but nothing seems to be working. any ideas?

the player prefab has the network object component, and the network transform component

i can see that the relay and lobby services are being used in the unity dashboard, but for the sake of the video and debugging i went back to the basic local multiplayer hosting

{
    [SerializeField] private Button joinButton;
    [SerializeField] private Button hostButton;

    private void Awake()
    {
        hostButton.onClick.AddListener(() =>
        {
            NetworkManager.Singleton.StartHost();
        });

        joinButton.onClick.AddListener(() =>
        {
            NetworkManager.Singleton.StartClient();
        });
    }
}```

I have this script, with assigned join and host buttons. these all work fine. i can see in the hierarchy that the players are joining the same game

But then the players are not updating their location on the other devices

[mortal vessel]

If you were making a stock market game in Unity which networking framework would you use

[sharp axle]

The players are moving locally but not across the network? Should you be using a client network transform instead? We'll need to see you player movement script

[bronze tendon]

{
    private void Update()
    {
        if (!IsOwner)
        {
            return;
        }
        Vector3 moveDir = new Vector3(0,0,0);
        if (Input.GetKey(KeyCode.W))
        {
            moveDir.z += 1f;
        }
        if (Input.GetKey(KeyCode.S))
        {
            moveDir.z -= 1f;
        }
        if (Input.GetKey(KeyCode.A))
        {
            moveDir.x -= 1f;
        }
        if (Input.GetKey(KeyCode.D))
        {
            moveDir.x += 1f;
        }

        float moveSpeed = 3f;
        transform.position += moveDir.normalized * moveSpeed * Time.deltaTime;
    }
}```

the same code *CodeMonkey* used in his video

[sharp axle]

Depends on how real time you need it. Any of them should work fine for basic stock simulation

[waxen quest]

How can we make Kick / Ban system?

I am using Unity Netcode, relay and lobby together

[sharp axle]

Ok, that is going to need a client network transform to work. Currently it would work on the host but no where else

[waxen quest]

The kick feature can be made by calling RPC on target client for disconnection but how to implement Ban system?

[bronze tendon]

but it does, no?

[sharp axle]

That's a Network Transform but not a Client Network Transform
https://docs-multiplayer.unity3d.com/netcode/current/components/networktransform/#owner-authoritative-mode

[mortal vessel]

It would be okay if the client updated in 1 minute

[sharp axle]

Bans are a bit more complicated. There is a Moderation Service but I think it's still in alpha. I think right now the only way to ban a player is manually through the Dashboard or maybe with Cloud Code API

[waxen quest]

Ahh I see

[bronze tendon]

I added the client network transform, and it works now! thanks. But what I'm confused about is that i the exact steps from the video (which uses network transform), not even a week ago, and everything worked. and suddenly it broke down without me changing anything

[sharp axle]

You could also use cloud code if you go for a serverless architecture

[gaunt summit]

Hi all, was just exploring Fish-Net's documentation, do they no longer have examples?
Not sure if blind

[sharp axle]

Network Transform is server authoritative only so that move script will not work with it. I'm pretty sure code monkey used client network transform there too. Or he was just demoing on the host

[gaunt summit]

Their own link on Github pages just gives Page Not Found

nvm I fixed it, I figured out I had 2 instances of my player

[fringe imp]

thanks but its not a child object.

[sharp axle]

Ah you're right, I totally misread that. No reason that shouldn't work

unless its not in a NetworkBehavior

[fringe imp]

its ok no worries, i re did my code, its working but i have no idea why, one sec

[ServerRpc(RequireOwnership = false)]
    public void SpawnPlayerServerRPC(ServerRpcParams rpcParams = default)
    {
        
        ulong senderClientId = rpcParams.Receive.SenderClientId;
        
        SpawnPlayersOnClients(senderClientId);
        SpawnForClientRPC(senderClientId);
        
    }
    
    [ClientRpc(RequireOwnership = false)]
    public void SpawnForClientRPC(ulong clientId)
    {
        Debug.Log("I Sent this to the server Client # " + clientId);
    }

    void SpawnPlayersOnClients(ulong clientId)
    {
        
        GameObject player = Instantiate(playerPrefab, spawnPoints[0].transform.position, Quaternion.identity);
        
        var playerNetworkObject = player.GetComponent<NetworkObject>();
        
        playerNetworkObject.SpawnAsPlayerObject(clientId);
    }```

 playerSpawnManager.SpawnPlayerServerRPC();

and then i call it here @sharp axle

but theres nothing inside of the client rpc @sharp axle so i dont understand why its working, because without the clientrpc it does nothing

ok so nvm its working without clientrpc.

the whole issuse was i called the spawn when a timer was over

[sharp axle]

I was about say...

[fringe imp]

and the timer was sending rpc to update client for timer

i wasnt using a network variable. love wasting 8 hours when im just dumb. i was like i swear this should work

thanks for the help!

[violet tapir]

Hello, I want to make a multiplayer game with photon , but I have the problem that I have 2 "Resources" folders (one for TMP and the other for Photon) can someone help me to fix it?

[sharp axle]

That shouldn't be a problem

[violet tapir]

Really?

ok, then I have no clue why the objects doesn't Instantiate

[sharp axle]

As long as the items have unique names that won't be an issue. But I know very little about Photon

[violet tapir]

is it valid in your opinion?

[violet tapir]

I just saw that someone in the internet had that issue (didnt expained how he solved it),which is why I assume that it is the same case here.

[fluid walrus]

iirc this should be fine?

what are the names you're passing in?

[violet tapir]

the names of the two prefabs in the picture

[fluid walrus]

can you debug or log those out to make sure they match? it's possible for names saved in assets not to match their filenames

[violet tapir]

ok

no

[violet tapir]

they match

[fluid walrus]

is it logging an error?

[violet tapir]

For some reason it works now

Im really confused right now

[fluid walrus]

if it started working after recompiling, could be some static state inside the library that needed clearing

[violet tapir]

ok, thanks anyways

[rapid crater]

I am looking for a Netcode tutorial that covers Data Persistence. Do any of the official project samples cover that? Or, can someone just point me to a tutorial that does

[sharp axle]

That's not really a Netcode thing. But you can look up tutorials on Unity Cloud Save or really any cloud storage like Amazon S3 buckets

[rapid crater]

Very true. Looking at UGS now, thanks

Hello there i know this isnt the best place to ask this but a friend of mine uses the playmaker visual scripting tool and would like have access to either Network for game objects or Fishnetwork.The problem is i am unsure of how to make a networkbehaviour talk to playmaker.If any of u guys used pm before and moved to c# any advice would be helpful

[sharp axle]

Playmaker has their own discord that could probably give a better answer

[zealous seal]

Hi guys, when I put this if (view.IsMine) on the update function, for some reason my character does not recognize that it is stepping on the ground

https://gdl.space/ulihacihih.cpp

[hazy sonnet]

how do i spawn a camera for a client and not replicate it across clients?

[sharp axle]

You do not spawn the camera. You can just instantiate one locally if its not in the scene or on the player prefab

[hazy sonnet]

ok, i did that. for some reason it still appears in the hierarchy (i instantiate it in OnNetworkSpawn())

[sharp axle]

You need to make sure that only the local player is instantiating a camera

[dreamy condor]

Will it cause server lag if I do a session ID check in void update()? If yes, what are the other ways to do it?

[sharp axle]

That depends on what the session Id is and how you are checking it

[winged yoke]

Has anyone here worked on a multiplayer project that used both networked monobehaviours and networked entities together? If so, are there any resources you'd recommend, or best practices to keep in mind?

[median viper]

How can I use Mirror networking with my inventory system? I have methods that are typically used in an inventory system like AddItem, PickupItem, RemoveItem, and a method to instantiate the item as a child of an inventory slot. Any help would be appreciated.

[sharp axle]

You wont be able to use both Netcode for GameObjects and Netcode for Entities at the same time.
You can mix regular Entities or GameObjects with either Netcode just not both Netcodes at once

[winged yoke]

oh interesting, could you elaborate on why this is the case? Or do you have any references I could read through to understand the differences?

[sharp axle]

They both use Unity Transport so you would need like 2 network cards to use them both. The official docs are pretty good. I don't think I can post links here but they should be in the pinned message here

[winged yoke]

Thanks for the info!

[granite stump]

Hello. I'm making a 2 player game. The host creates a lobby and the client joins. After the game ends they both go back to the main menu, leave the original lobby and the host/client is stopped from the Network Manager ( using NetworkManager.Singleton.Shutdown() ). The problem I have is that the original host can't host again, I get this error: "Host is shutting down due to network transport start failure of UnityTransport!".

[sharp axle]

Which Transport are you using? I've heard the Steam transport running into this issue of not shutting down correctly

[granite stump]

Unity Transport

I tried to change a couple of values, but I set them back to the default ones

[sharp axle]

Does the main menu have a network manager already in it? You might be getting duplicates

[granite stump]

The Network Manager is only present in one initial scene that I never go back to

[sharp axle]

Huh, dunno what the issue is then. Have you tried checking Allow Remote Connection? It shouldn't matter connecting to localhost though

[granite stump]

I haven't, I will give it a try

Doesn't work. Is there a reset for the NetworkManager or something?

[sharp axle]

Shutdown() is the reset

[granite stump]

well, it shuts down the Network Manager but I can't start the Host again. I tried destroying it and instantiating a new one but it doesn't work

[zealous seal]

Hi guys, when I put this if (view.IsMine) on the update function, for some reason my character does not recognize that it is stepping on the ground

https://gdl.space/ulihacihih.cpp

Sounds like you are not the owner of that character for whatever reason

[granite stump]

Why does a NetworkList result into a memory leak?

[blissful jay]

[west lance]

hey, does anyone have experience with networking in photon fusion 2?
im trying to make a game manager singleton that syncs with every player (to control a lobby screen)

but im not sure where to start

i have functional player syncing (so i can walk around on one client and it syncs to to the other)

[mint anvil]

i have a question, my game has multiple teams, and every team has a network variable for their money, if i create 4 network variables but only 2 teams are playing, does that affect network performance, and is there a better/dynamic way of doing it? (currently in code i check if (team == 1) {teamValues.Instance.team1Money.Value -= money} else ... and so on and i think that is not that efficient)

[sharp axle]

That should be fine. Network Variables only get sent when they change values.

[median viper]

I am trying to network my inventory system and I have a small issue, right after I made the InitialiseItem method into a ClientRpc call, Unity gives me an error with the item icon, it said "texture data is either not readable, corrupted or does not exist", here's the code which contains the method, ive also included the item class https://pastie.io/jrzlvc.cs

this is Mirror btw

[sharp axle]

You can't just send a ScriptableObject over the network like that. Usually I will have a List or Dictionary of SOs that I can reference by id. Then you only need to send IDs around

[median viper]

So make a list of type Item?

If so, how can I implement that because I don't really get how I can use IDs instead of the scriptable object itself?

[sharp axle]

Either use the list index as the id or add an id field in the SO. You can use Linq to search the list

[median viper]

alright there is already an id attribute in the SO so I guess I will try that first.

thank you

[fringe imp]

what should i make my tickrate for a non compettive p2p arena game? 4v4 physics based

[sharp axle]

Tick rate should be the same as your physics step. The default should be fine.

[sharp walrus]

I'm making a game that has both singleplayer and multiplayer, but want to be able to reparent network objects while in the single player mode, is there a way to essentially start a host for single player without actually needing an Internet connection or anything?

[sharp axle]

You don't need the Internet to connect to localhost

[sharp walrus]

Oh duh, for some reason using that never crossed my mind, thanks

[zealous seal]

I REALLY NEDD HELP

Start() is probably getting run too soon before the network is connected

[median viper]

Yesterday I asked about networking my inventory system. Since I cannot pass scriptable objects across the network, I have made a dictionary of items which allows me to retrieve the items by ID. It works but I am only having a problem with the item's sprite, a white box appears inside my inventory slot instead of the icon of the item itself. https://pastie.io/vljpuv.cs

I've included 3 relevant scripts in the pastie

[sharp axle]

I guess you'll also need to show the code for the item slot. Or is the image sprite not getting set to the item icon?

[median viper]

Okay so now when ive setup some debug logs it gives me a debug log says "Item ID not found". I have my Items folder placed inside a folder called Resources. And also yeah the image sprite is not getting set to the item icon but that's obviously because the item itself is not being found.

https://pastie.io/vcvgjd.cs

Sorry nevermind, I made a check so that it logs the names of the added items and it actually logs them in the console by doing this

foreach (Item item in items)
        {
            itemDictionary.Add(item.id, item);
            Debug.Log(item.name);
        }

[sharp axle]

Either the id is not getting set in the item SOs, or the InitialiseItem() is getting passed the wrong id

[median viper]

so I am not sure what the problem is with the icons

[median viper]

I will try to find out where the problem is coming from then. Thanks.

[sacred schooner]

public class EnemyHealthComponent : NetworkBehaviour
{
    public int maxHP = 10;
    public NetworkVariable<int> HP = new();

    public override void OnNetworkSpawn()
    {
        HP.OnValueChanged += onHpChanged; //updates the value on a hp bar slider
        healthBar.maxValue = maxHP;
        healthBar.value = HP.Value; //cursed line!!!
        if(!IsServer) return;
        HP.Value = maxHP;
        //SetHPServerRpc(maxHP);
        //print("HP set to "+HP.Value+"!");
        base.OnNetworkSpawn();
    }

this is my code for simply updating the hp of an enemy when damaged. This works great everywhere, EXCEPT for the initial HP=MaxHP value for all clients. All enemies are server-owned. Since I set the callback on all clients first, and then replicate the initial value only on the Server, all should nicely initialize, no? NO

for some reason chatGPT recommended adding this line:
healthBar.value = HP.Value; //cursed line!!!
this worked, but is exactly the same thing that should be called by OnHpChanged:

    private void onHpChanged(int prev, int curr){
        print("HP changed from "+prev+" to "+curr);
        healthBar.value = curr;
    }

I am still wrapping my head around as to why. From the Clients' POV the HP value could still be not initialized, so trying to set it to the slider seems counter-intuitive, yet works... How can a networked variable be initialized and synchronized with a value faster than the server-called function initializing it??? And most importantly, why does the onHpChanged callback work always, but the first time?

Only idea I get is some race condition, where the server goes through it's onNetworkSpawn first, sets the value, then the client subscribes to the callback, but has no clue about anything being changed. Does that sound possible, and if so, how would you ensure this does not happen. The entire reason for NetworkVariables was to easily synchronize across all clients, including late-joiners, but there's still many work-arounds you need to for this to be true

[sharp axle]

OnValueChanged is not called when the object is first spawned. So you would need to call onHpChanged manually or set healthBar.value directly in OnNetworkSpawn

[sacred schooner]

so the event literally called "onValueChanged" is not called, but according to the docs the value is changed...?

" A NetworkVariable.Value is synchronized with:

Newly joining clients (that is, "Late Joining Clients")
When the associated NetworkObject of a NetworkBehaviour, with NetworkVariable properties, is spawned, any NetworkVariable's current state (Value) is automatically synchronized on the client side."

[sharp axle]

Yea. the naming can be kinda misleading. On Spawn the variable value is already up to date so is not technically changing

[sacred schooner]

I can imagine this question appearing very often due to the naming convention, perhaps a short mention about it in the docs would save a lot of frustration and time. Good to know I'm not crazy, thank you!

<@&502884371011731486> i believe to be in the wrong channel

[river gazelle]

I'm making an idle game with semi-multiplayer.
My game uses Unity and UGS C# Cloud Code Modules with UGS Cloud Save.

Players click "start" which then starts idle/automated combat on the client. Players get experience and items from combat.
I want this to happen real-time on the client, it takes too long to pre-generate all the combat and loot on the server.
But I want my server to check everything so there's no cheating.

I want to prevent cheating because trading items between players will be a big part of the game.

My plan at the moment is the following:

• player starts the game and sends a request to the server for a Random Number Seed (RNS)
• server generates the RNS and stores it in Cloud Save then sends it back to the player
• player clicks "start" and combat is processed real-time using the RNS, items are also generated using this
• on significant events, for example level up, every 10 seconds or on an item drop, the client pings the server to let it know something important happened
• the server then re-calculates all the combat up to that point and if everything checks out it saves all the rewards to Cloud Save
• the sever then generates a new RNS that will be used after the next event (to prevent players calculating rewards a long time up front)
• on the next event the client pings the server again and then starts using the new RNS

The issue I have is my combat logic must run on both client & server, so I have duplicate code that I need to keep in sync. How can I manage this?

Does anyone know how to add different game modes to my game?
I mean when you are in the main menu you can select a game mode and you get send to that server? With Steam API.

[sharp axle]

Remove the player prefsb from the network manager and spawn the players manually after the next scene loads. You might have to listen for scene events if you want to wait for all clients to load that scene

You have to disable the camera on the remote players. Unity will only show one active camera int the scene. You can get around that if you are using cinemachine

I want to shoot as a client but if I create a clientprc it just doesn't work for the client, it doesn't shoot nothing.
However this is all server side spawning, which makes the bullet "desynced"
Whats the solution?

[stable shadow]

With KCP and transport, how do I debug exactly what message is '1459' ?

Im getting it unregistered in very specific circumstances, but I can't seem to track down what it is or where/when/how to debug it

[median viper]

Do I need to put a separate canvas for each player instance?

[sharp axle]

Normally the UI canvas is not networked at all. Unless its a world space canvas

[median viper]

well the problem is, my Inventory slots are always apparent on screen and there are 4 of them, I need to add their prefabs in a list in the Inventory script that is attached to the player but I cant because the player isnt in the scene

obviously the player only gets instantiated when someone joins the lobby

the 4 slot prefabs have the scene canvas as their parent

[sharp axle]

You can have a separate UI Manager script that listens for players joining the lobby. Or have the players register themselves to the UI manager when they connect. The UI manager can then instantiate or bind your inventory data to the UI

[median viper]

Alright thanks

[old seal]

Im noob. I saw that for multiplayer, you have to use code so that a game instance has both the host and the client code and dependinf on what it is, it runs the code accordingly. But if the game can be played single player, how is the code now? Is it a fake host with local ip, or a total dofferent program for singleplayer? Hope it makes sense what im asking.

[frozen acorn]

H-hello. May I ask, haven't found a backend channel here, so.. here? if it's okay
I have some exp with Unity, 0 exp with any backend though.
I'm trying to add multiplayer, matchmaking, login and simple data save/load to my webgl game.
Multiplayer part looks like something I at least know how to start making(with the help of Fishnet), but backend sadly nowhere near.
My utmost priority is self-hosted open source(~zero cost, no premium/pro/enterprise tiers to be accurate) solutions or even making these parts myself. Best I could find is xsolla backend(no tiers, % of income though), but maybe I somehow missed something obvious?
If no such solution exists, where should I start with these things(matchmaking, login, save/load data)?

[sharp axle]

The easiest way to do single-player without duplicating a bunch of code is to host to the localhost.

[sharp axle]

I'm not sure there is a true zero-cost solution to server hosting. Even if you host the dedicated server on a old pc in your closet, you still have to pay for bandwidth.

The Epic Online Services and Steamworks are free to use as well.

[frozen acorn]

No-no! Not to server hosting, sorry, this is alright. To backend I meant

Dedicated server model. But I don't have an ability to pay for backend. Either open source or my code

[sharp axle]

There are no turn key solutions for self hosted backend infrastructure like that. You'll need to build and host the database, matchmaking, lobby, and authentication servers yourself. Not to mention maintaining the security of player data.

[frozen acorn]

Sounds sad, where should I start then?

[sharp axle]

Honestly, I would start with using one of the Backend as a Service. Once you know exactly what you need, you can start to strip it out and build your own if needed.

[frozen acorn]

I see, thank you! By the way, do you know anything about xsolla backend?

[sharp axle]

very little. We talked to their booth at GDC. They are legit though. Personally I'm sticking with the UGS backend

[frozen acorn]

Okay! Thanks a lot!!

sorry I have one more question, wouldn't it be easier if I networked the UI and made it as a child of the player instance?

[sharp axle]

The main issue is that you can't spawn a network object as a child. You have to represent it after you spawn. And that jacks up the UI. Im sure that there are ways to deal with that but it just seems like more trouble than it's worth

alright fair enough, thanks again

The `OnRoomListUpdate` function does not work for some reason

[ripe mesa]

maybe because you are not in a lobby yet?

but im yes

I understood why this happens.
A certain parameter is missing that causes the function not to be called, but which one?

Has anyone ever dealt with XR Sockets in a VR project over a network while using Netcode for GameObjects? I am continuously running into the problem that once an object enters the socket it cannot be removed on the host and client side. I am using Client RPC's to change socketActive but it does not seem to be doing much. Been stuck on this for weeks...

[split hedge]

Well can you help?

[flint bluff]

Hello guys, I'm trying to polish my multiplayer prototype and I have some issues to set the correct player to Cinemachine virtual camera, IDK why but my event subscriber doesn't call :

using UnityEngine;
using Cinemachine;
using System;
using Unity.Netcode;

public class PlayerCameraFollow : NetworkBehaviour
{
    [SerializeField] private CinemachineVirtualCamera virtualCamera;

    private void Start()
    {
        virtualCamera = GameObject.FindWithTag("Camera").GetComponent<CinemachineVirtualCamera>();
    }

    private void OnEnable()
    {
        GameManager.OnGameInitialize += OnGameInitialize_SetCameraFollowTarget;
    }

    private void OnDisable()
    {
        GameManager.OnGameInitialize -= OnGameInitialize_SetCameraFollowTarget;
    }

    private void OnGameInitialize_SetCameraFollowTarget(object sender, EventArgs e)
    {
        if (virtualCamera != null && this != null && IsOwner)
        {
            virtualCamera.Follow = transform;
        }
    }

}

Any ideas? here's my part of the code in my GamaManager when I call OnGameInitialize invoke:

public static event EventHandler OnGameInitialize;

public void StartRound()
    {
        OnGameInitialize?.Invoke(this, EventArgs.Empty);
        isGameActive = true;
        isPlayerAlreadySpawn = true;
    }

I want to shoot as a client but if I create a clientprc it just doesn't work for the client, it doesn't shoot nothing.
However this is all server side spawning, which makes the bullet "desynced"
Whats the solution?

[fringe imp]

good morning everyone!

my scripts are grabbing the reference to the clones gameobjects instead of mine, any idea how to make sure it only grabs the owners only?

[sharp axle]

First, you'll need to make sure the correct muzzle position and rotation are set.
Second, make sure there is a network rigidbody so that the velocity is getting synced.
If BulletScript.parent needs to be synced back to the client then it should be a Network Variable.

[sharp axle]

Where is StartRound() getting called?

[fringe imp]

https://docs-multiplayer.unity3d.com/netcode/current/terms-concepts/distributed-authority/

does unity not provide this? cant find anywhere how to implement distributed auth

[split hedge]

Why would a transform be a networkvariable? I just want so the bullet is not desynced on the client and is shot right after I click

[sharp axle]

You might not need it at all. I have no idea what you are doing with the parent

[sharp axle]

this is part of the NGO 2.0 experimental branch. You'll need Unity 6 to install it

[fringe imp]

doesnt work /:

[split hedge]

So my problem is when I shoot the gun on the client, it looks like it waits .5 ish seconds and then shoots it which makes it desynced.
On the host it works, since it is a server rpc, so how do I spawn the bullet on the client and verify it on the server?

[sharp axle]

Ok, thats just lag not actual desyncing. You can either just instantiate bullets locally or you can try out the distibuted authority in 2.0
https://docs-multiplayer.unity3d.com/netcode/current/terms-concepts/distributed-authority/

[sharp axle]

You'll need to install it by name. and the version is 2.0.0-exp.2

[flint bluff]

I debug my StartRound, it's called normally, actually It's called when the player it's enable

[sharp axle]

If you are subscribing to and invoking in OnEnable(), You are likely running into a race condition. Change the player Start() or OnNetworkSpawn()

[flint bluff]

actually I'm invoking on Awake let me try

tysm, it works

🙂

[sharp axle]

yea. Awake() is before onEnable()

you're right, my mistake

[spiral lark]

I'm planning on making a game where people can play card games with other players and I'm thinking about using mirror. I want my game to support

• Playing against a "bot"
• Playing against up to 8 other players
• Playing against players invited by a player
• Playing against players joined by some sort of simple matchmaking system

If possible, I dont want to have to pay for any networking costs and have everything work peer to peer

Which multiplayer service do you guys reccomend?

[ripe mesa]

play card games, is it turn based? what platform is it?

[spiral lark]

turn based i think and itll be like mac windows linux maybe webgl but prolly not

[ripe mesa]

Fusion shared or pun no doubt

[split hedge]

How do I instantiate them locally and then sync them to everyone?

[split hedge]

I have this, but on the client it doesn't spawn it and it just floats in the air without moving

[sharp axle]

I would use the new [Rpc(SendTo.Everyone)] to just instantiate the bullet and set its velocity
I would send the position and rotation in the RPC
You don't need to Spawn() in that case.
I would also have the bullet script itself set its own velocity

[teal cedar]

Why I cannot see those virtual players?😭 Multiplayer Play Mode

[crisp egret]

hello I need help about my code for short i create a moba and I use photon (PUN) for the multiplayer and I don't understand who send to every player info about a variable
in red variable i need to send

I think i need to use RPC but don't understand how it works

[sharp axle]

It will need to be an RPC and you will probably need to send the the position instead of the entire gameobject

[crisp egret]

and who can i do that

[sharp axle]

I don't use photon. You'll need to read up on the docs

[timid sinew]

What is the multiplayer tech behind mtg arena and hearthstone

For data sync and simulation

[sharp axle]

You need to make sure that only the local player is running the update. You should probably just disabke the player controller on the remote players

[sharp axle]

You can't send a gameobject in an RPC. Just send the collider.tranform.position

[wide ferry]

is this a bug in netcode or am I being bald

so I have a player object that is set to spawn in by the network manager, and its runs this coroutine on Start()

[sharp axle]

It's likely a custom web server of sorts. Games don't usually discuss their network architecture unless it's a gdc talk somewhere

[wide ferry]

for some reason, setting stest throws a warning saying that the object might not be spawned (despite the fact that it is)
and an error is thrown if I try to change PlayerID, which is the same as stest exept its a FixedString128Bytes.

[sharp axle]

Don't run it on start. Use OnNetworkSpawn instead

[wide ferry]

fair

but that wouldn't fix the problem

unless its taking over 5 seconds to spawn it

also I specifically told it to wait until it actually is spawned

anyway, tracing the error it seems to come from here saying "object reference not set to an instance of an object"

thats in the NetworkVariable.cs file from netcode

was wondering if there was anyway to modify this file to delete this line, it keeps undoing my edits if I try

or if there is any way to not make unity die

[sharp axle]

The problem is that the object not spawned. I'm not even sure the isSpawned property is properly initialized by the time start() runs.

[wide ferry]

ok

but it is spawned

[sharp axle]

Start() runs before the network manager connects to he network

[wide ferry]

im aware

but this code runs way after its connected

I just threw together that example to try and see if I could figure out why it wasn't working, but I haven't been able to find anything

[wide ferry]

so does this spawn the object before its connected to the network?

because thats whats spawning the player lol

again, this is the code thats running

stest appears to work with a warning in the log, but PlayerID doesn't

[fresh pasture]

the code works but brakes when i add animations

[sharp axle]

For dynamicly spawned objects Start() is after OnNetworkSpawn for in scene objects Start() is before. I always just stick with OnNetworkSpawn.
If it's only the fixedstrings that's failing then that might be a bug. 1.9.1 made some changes to network variables that could have introduced some bugs

[wide ferry]

im in 1.7.1 since im in 2021.3.19

[sharp axle]

Weird. Fixedstrings worked fine then. If you can reproduce that in a fresh project then open a GitHub issue on it

[wide ferry]

wack

so im doing some testing

this also does not work

and neither does the "safe" varient of WriteValue

I can prob get around needing network vars for strings, its just annoying

[crisp egret]

sorry don't understand

[sharp axle]

gameObject is not serializable so you can not send it over the network in an RPC

[crisp egret]

yes that I understand now , but who can i do ? (sorry my english)

[wide ferry]

me out here just making my own network variables because netcodes wont work

[sharp axle]

If you only need the position then you can send collider.transform.position instead of collider.gameObject

[untold anchor]

Hey not sure if this is the right channel bc I havn't used this in ages. I am having trouble with my Unity Server (Unity's Lobby and Relay System.) The issue is in my bootstrap code but is showing no errors and I have been stumped for days...

[open mirage]

I have a dedicated server architecture multiplayer game. While I am planning on setting it up on Unity's Game Server Hosting, I don't plan on using it (since it costs). Since my game is lightweight, I could simply start up a dedicated build instance whenever my friends want to play. I don't know how to do things like "port forwarding" and "NAT Punchthrough." Most of the tutorials I find are for Relay or Game Server Hosting (Multiplay), can anyone point me to tutorials on how to make a player-hosted dedicated server?

[teal cedar]

Why multiplayer play mode doesn't work with unity 6 preview?

It always shows a timeout when opening a virtual player window

[sharp axle]

Whoever is running the server will need to setup port forwarding on their router. That process is different for every router.

[sharp axle]

I don't know what error you are getting but I use MPPM in Unity 6 so it does work. I had some error when I first updated and had to delete the Library folder and restart Unity

[teal cedar]

I will try

[teal cedar]

Are you working with unity 6 preview?

[sharp axle]

yep

[teal cedar]

Here. MultiplayerPlaymode]: Timeout reached for client message 'OpenPlayerWindowMessage:0d0dc11b71824956b50030438f99cb19'

[teal cedar]

This is weird. I can hear the intro sound two times but I cannot see that virtual player window

[sharp axle]

Are you using MPPM 1.0?

[teal cedar]

I'm using 1.0.0

[teal cedar]

So yes

[teal cedar]

So when you have two players activated (main editor + 1 virtual player) and then you click play then the editor will start playing and a new window will be opened?

[sharp axle]

You should be seeing the virtual player window even before you hit play

[teal cedar]

And where can that window be?

[teal cedar]

In that case, either it is hiding somewhere because I can hear audio or it's an error and I will delete the library and restart

[sharp axle]

its technically a separate editor, but if you are hearing it then the process is running somewhere

[sharp axle]

when you check the virtual player you should be seeing a new editor start up

[teal cedar]

You mean completely new editor running?

[sharp axle]

yes

[teal cedar]

No, I can't see it 😭

[teal cedar]

I can see how it's only activating then it's active but no new editor

[teal cedar]

Should I show it in explorer and then manually open that virtual player?

[sharp axle]

I don't think that will work. Does the same thing happen with player 3 and 4?

[teal cedar]

Yes. Simply, those virtual players won't show up

I will try deleting the library folders.

[teal cedar]

Now I am hearing intro four times

[teal cedar]

And will focusing work?

https://docs-multiplayer.unity3d.com/mppm/current/virtual-players/virtual-players-focus/#focus-play-mode

[sharp axle]

i don't know, maybe. But if you aren't even seeing the window, I'm not sure it will work

[teal cedar]

So in your case, when you enable the second virtual player then a completely new window opens? Once a virtual player is activated?

[sharp axle]

Yes. A whole new editor will load and import assets

[wide ferry]

Just a question about network variables, why can’t you use strings?
I know you can use fixed strings, but I’m pretty sure not normal ones, and it doesn’t make much sense to me since you are able to strings in RPC methods

[sharp axle]

in the earlier version Network Variables would only support value types like structs. Strings just weren't part of the built in types supported

[austere yacht]

Strings have an unbounded size and cannot be sent efficiently over static buffer sizes

ie they would make it impossible to have a zero allocation netcode framework

[sharp axle]

In the latest versions of NGO they added support for the Lists and Dictionaries so strings should be less of a problem

[wide ferry]

But they work in RPCs, does this not have the same problem?

[austere yacht]

I suppose you are free to implement non-smart things in RPCs then.

anything that’s not a primitive value or struct thereof isn’t ideal to be synchronized through a high performance realtime game networking framework

you can sync lists etc, but the expectation is that you know and understand the tradeoffs of doing that

Potentially unity has added support for unbounded types for convenience reasons, since in many situations people do not care at all about performance. And for them it’s just frustrating if they can’t send a novel and json files through a RPC for init/setup etc.

[sharp axle]

Its also pretty easy to set up a custom serialization from a string to a fixedstring

[teal cedar]

Looks like I am not the only one with this error. https://forum.unity.com/threads/virtual-player-no-showing-up.1575088/

[sharp axle]

Do you also have the a* Pathfinding asset? I saw that thread when I was having my issues.

[teal cedar]

No, but I have a lot of assets from Unity asset store

[teal cedar]

But I tried to make a new project without anything and I enabled virtual players and still nothing.

[teal cedar]

I have that timeout warning

Will this help?

[sharp axle]

Maybe, if your issue is that language bug

[sacred schooner]

After adding nothing related to spawning players, I suddenly can't spawn a player on a client join... a host player is spawned fine, but the client prefab is not spawned on either instance, making this fail:

    public void onPlayerJoined(ulong playerId)
    {
        print("onPlayerJoined "+playerId+" ");
        if(!IsServer) return;
        print(NetworkManager.ConnectedClients[playerId].PlayerObject.name);
        var player = NetworkManager.ConnectedClients[playerId].PlayerObject.GetComponent<PlayerController>();
        

after attempting to get the newest connected client. onPlayerJoined is subscribed to the NetworkManager.OnClientConnectedCallback += onPlayerJoined;
It is mind-bending why adding a few Mono-behaviors results in the clients not being able to connect. This is the exact error I receive when trying to get a [playerId].PlayerObject

MissingReferenceException: The object of type 'NetworkObject' has been destroyed but you are still trying to access it.
Your script should either check if it is null or you should not destroy the object.
UnityEngine.Object.get_name () (at <30adf90198bc4c4b83910c6fb1877998>:0)
GameMaster.onPlayerJoined (System.UInt64 playerId) (at Assets/Core/GameMaster.cs:27)
Unity.Netcode.NetworkConnectionManager.InvokeOnClientConnectedCallback (System.UInt64 clientId) (at ./Library/PackageCache/com.unity.netcode.gameobjects@1.7.1/Runtime/Connection/NetworkConnectionManager.cs:45)

if I remove the code calling for it the issue persists until I reference the connected clients somewhere else. Googling and browsing docs results in nothing, was wondering if anyone got a cure for this

What is even more bizzarre is that when the client joins, the host-client is correctly replicated on the client, and the connectedclients count is correct (2),but when it comes to spawning the client playerObject, it's gone. I am not destroying the playerobject anywhere in my code (didn't implement dying and exiting, they are eternal)

Best hope is reverting changes made so far and doing baby-steps to see what failed, but that's some hours I would prefer to not lose... thanks in advance

Has anybody dealt with inconsistant crashes in your development builds? Me and my coworker have recently noticed game crashes, we can find them dating back to versions of our build we had 4 months ago ... But it only happens like every sixth time that we test it.

[junior sapphire]

Hi, I have a question about using Cross-play with Game Server Hosting to enable cross-platform gaming. I'm looking at the example code below

// Create a UDP driver
var udpDriver = NetworkDriver.Create(new UDPNetworkInterface());
udpDriver.Bind(NetworkEndpoint.AnyIpv4.WithPort(7777));
udpDriver.Listen();

// Create a WebSocket driver
var wsDriver = NetworkDriver.Create(new WebSocketNetworkInterface());
wsDriver.Bind(NetworkEndpoint.AnyIpv4.WithPort(7778));
wsDriver.Listen();

// Add both drivers to a new MultiNetworkDriver.
var multiDriver = MultiNetworkDriver.Create();
multiDriver.AddDriver(udpDriver);
multiDriver.AddDriver(wsDriver);

As per the sample, the udp and web socket drivers are bound to different ports. Multiplay (Game Server Hosting) only returns a single port when getting an allocation config BUT are all the ports in between allocations open too? E.g. when my Multiplay servers start, available visible ports are 9000, 9100, 9200 etc. BUT every port in between is also open and can be bound/listened to?

Does that mean for Cross-play setup, its as simple as binding the udp driver to port 9000 and binding the web socket driver to 9001?

[junior sapphire]

Hmm. It does indeed look like the intermediate ports are available to bind to. Just tried binding to 9001 and connected no problem.

[open mirage]

I have a dedicated server build, and when it's starting up I get 4-5 Curl error 6, could not resolve host. This doesn't appear in editor console logs.

Hi , did you know this error : NetworkRoomManager no RoomPlayer prefab is registered. Please add a RoomPlayer prefab. I try to configure my NetworkRoomManager , i create a prefab for the RoomPlayer prefab but its didnt working

[teal cedar]

How to manually spawn player?

Netcode

[sharp axle]

First, remove the player prefab from the network manager. Then you can call .SpawnAsPlayerObject(clientId) on any network object you want from the server
https://docs-multiplayer.unity3d.com/netcode/1.9.1/basics/networkobject/#creating-a-playerobject

[teal cedar]

Should I get that client ID from NetworkManager.Instance.LocalClientId?

[sharp axle]

That would need to be the client id that you want to own that player object. If you use local client id from the server then the server will own it.

[urban blade]

hello, quick question, currently all I want is for 2 players to be able to play a turn based game, I am trying to avoid a server as this is just a turn based, everything that a user do, can be sent in a similar pattern as notification. The other player's game will just wait for those notification and update the games state.

Now, my question is which tools or library is best for my use case? an example would be a tictactoe game.

I have read playfab but is it really necessary

[delicate sandal]

Hello everyone, I have a question regarding networking(not sure if this is where I'm supposed to ask in, I apologise if it isn't)
So I'm planning on getting a server PC for my unity game so I can run the whole multiplayer system on that server pc instead of relying on cloud hosts, my question is what do I need to make it work? What programs do I use, how do I setup a cloud system on the server PC? If there's a tutorial out there that you can share I'd be greatly appreciated!

Learn about port forward and NAT

if your game blows up, now learn security

Hi everyone, I have big issue on my little 2d multiplayer game. I have create my map with a tile map with a tilemap collider 2d, a player prefab with Box Collider 2d and a rigidbody 2d ! All works well without the network part ! But when i add the network Rigidbody 2d, my player overlap on evvery prefab and tilemap... Really need help 🙏

[delicate sandal]

Would it work the same as Unitys Multiplay?

[ripe mesa]

on premis / self hosted is a little different

the concept is same for terraria/minecraft server hosting

[delicate sandal]

Would I be able to achieve something similar in the future? Because all I'm trying to do is to run my game through my own server pc and not use the cloud that they have offered

[ripe mesa]

the concept is same for terraria/minecraft server hosting

run minecraft_server.exe -port 25565 -maxPlayers 10

now you have to do the networking part, the NAT and port stuff I said

You can use Cloud Code for this. Here is a tic tac toe example using js Cloud Code
https://github.com/Unity-Technologies/com.unity.services.samples.use-cases/blob/main/Assets/Use Case Samples/Cloud AI Mini Game/README.md

And here is a chess game using c# modules
https://github.com/Unity-Technologies/com.unity.services.samples.multiplayer-chess-cloud-code

[delicate sandal]

Would the tic tac toe module be usable in a 3D game?

[sharp axle]

I don't see why not.

[delicate sandal]

And I can run that through a server pc I own?

[sharp axle]

No, Unity cloud code and cloud save are web services. But there is no reason you couldn't make your own node js server that do the same thing

[delicate sandal]

Is there a tutorial on how can I make one? Because I'd be better off running my own server through my own server pc than cloud it

[sharp axle]

there are tons of node js tutorials out there

[delicate sandal]

So okay, I've done the node js server and all that
Once I've done it, what's the next step to making it work with unity?

[sharp axle]

there is not really a next step. you make web requests to the node server

https://learn.microsoft.com/en-us/gaming/playfab/features/social/groups/using-shared-group-data

I guess this is what I am looking for

[sharp axle]

Yea. that's the same thing as Unity Cloud Code just using Azure Playfab

im watching a tut on how to make a game multiplayer and when deciding to join as a host or client the oyutuber makes 2 seperate buttons for them, and also, he makes those buttons in the same scene that the client would join on.

What if i want it to check if there is a server, and if not, join as a host, otherwise, join as a client, and to do so in a different scene, like from main menu scene, you click play, looks for server, lets say it found one, then it joins you as a client i nthe game scene

[sharp axle]

It depends on how you are hosting your servers. If you are self hosting then would need to use a relay service with a lobby system. Then you can look for all open lobbies and use it to connect to your server

[trail ibex]

im using unitys lobby and relay thingie, registered and downloaded all the packages and stuff

Hello everyone, does anyone here have a server hosted on AWS and the game running on itch.io?

I need help configuring the server to accept HTTPS requests.

I know I need the SSL certificate, but if anyone can help, I would be grateful.

I obtained the certificate using a different domain, not the itch.io domain. How do I proceed?

Hello everyone, apologies if this has been asked before, but i've just joined a multiplayer mmo style project, they are using NetCode for Entities, and plan on using a Dedicated Server.

I'm still ramping up, and they have followed the examples and demos in the docs: https://docs.unity3d.com/Packages/com.unity.netcode@1.2/manual/client-server-worlds.html

But I've got this funny feeling about the NetCode Client Target, it appears the only options are "Client" or "ClientAndServer"... and I'm confused, why would I want a client running on my headless dedicated server? I understand that if i change the platform to Dedicated Server, it adds the scripting define UNITY_SERVER that can be checked in code, but I refuse to litter my code with compiler flags, so I'm super surprised there is no Server target as far as NetCode is concerned and there are just never any client worlds allowed to be created in it just as if Client is the target there are no Server worlds allowed to be created.

Maybe the answer is just "because the system needs it, i can ignore it, it will never do anything" but that bugs me. We never plan to have a client host a server, so they should never be in the same process. I understand there's some "world" generation stuff going on that I'm still new to but has this been discussed before?

MaxPacketQueueSize
MaxPayloadSize

Are these values can be set at anytime or before Starting Host and Client?

[sharp axle]

I'm pretty sure they can be set at runtime. I'm not sure why you would be changing it after connecting though

[waxen quest]

In my case, There can be upto 20 Clients connected and i want to make sure these size vars updated based on the equation i fount on the internet

I call these whenever the client connects and disconnects.

Please correct me if i am wrong

transport.MaxPacketQueueSize = networkManager.ConnectedClientsIds.Count * 32;
transport.MaxPayloadSize = (networkManager.ConnectedClientsIds.Count + 10) * sizeof(float) * 3 * 3 * 10;

These changes on both client and host

[sharp axle]

What's the issue with just setting the max to the 20 client limit from the start?

[waxen quest]

I saw in a forum that setting these values high creates useless memory buffers

I can be wrong

Do I set these high already?

Also are these calculations correct?

[sharp axle]

Dunno. I've never had any issues from the defaults. Literally have never changed them

[waxen quest]

Ohh i see

[sharp axle]

If you are seeing dropped packed from a full message queue then you might have other issues going on

[waxen quest]

I didnt seen any. But i cannot test the game with 20 players. So i am not sure

Hi guys, hopefully quick question. When a RPC is called from a client to the server, if the code interacts with the scene hierarchy is it seeing the gameobjects of the server or the ones of the client that called it?

[sharp axle]

It would be wherever it's running. If the rpc is running in the server then it will be the server scene. If it's sent to other clients then it will be that client's scene

[nova creek]

Thanks appreciate it 🙏

If I am making a new game that I plan on making co-op capable, is it an ok plan to make the game itself first and then add multiplayer capabilities? Or does the co-op stuff have to be integrated into the codes from the beginning

[fluid walrus]

you can rework a game to add it in later, it's just harder than building around it from the start

[sharp axle]

If you add it later you'll end up rewriting most of you code.

[trail ibex]

can u explain how one would look for open lobbies if they are using unity relay and lobby

[real ravine]

Hey guys, I used the SimpleWebServer to test a WebGL build locally on localhost:8017, how can I stop the server from running?

[sharp axle]

You can query for lobbies with available slots, or any other variables you want to set
https://docs.unity.com/ugs/en-us/manual/lobby/manual/query-for-lobbies

[sharp axle]

I think you just have to stop the SimpleWebServer.exe process manually

[real ravine]

The problem is there is no SimpleWebServer.exe running on cpu

[sharp axle]

How are you running it?

[real ravine]

I ran through cmd, on simplewebserver dir, and then /SimpleWebServer.exe "build_dir" 8017

[ripe mesa]

terminate it through task manager

or cmd task kill command
