here

[real ingot]

k

give me a sec

show me the movement script

I meant

if(ChatInputField.isFocused) {
// Disable the movement here
}

[keen plover]

okay

https://hastebin.com/share/lofijusuce.csharp

here is player movement

but keep in mind this is multiplayer game so we cant disable every player when we write only myself

[real ingot]

do something like this
``if(ChatInputField.isFocused) {

}

else {
// Movement script in here
}``

[real ingot]

try using if(!isOwner) but I'm not quite sure

[keen plover]

like this?

[real ingot]

this is photon. I only know how to do this with netcode. So I can't really help you with that

[real ingot]

but by they way it looks I believe you should use isMine

if(!isMine) return;

in the beginning of the method

[real ingot]

and then use this after

[keen plover]

what about this

[real ingot]

does isOwner work in photon?

[keen plover]

i dont know

i got no error

[real ingot]

give me a sec I'll write it down

I think you should use isMine instead of isOwner. Unless isOwner is possible in photon too

again, not sure

give me a sec

[keen plover]

isOwner isnt possible i got error only now

i think my visual studio is broken it doesnt show errors i will work on that later tho

so i should use isMine?

isMine also doesnt exist

[real ingot]

if(ChatInputField.isFocused && photonView.isMine) {
playerMove.enabled = false;
}

else if(!ChatInputField.isFocused && photonView.isMine) {
playerMove.enabled = true;
}

here

don't place this code in the playerMove cause it won't go back to true then

[keen plover]

its in chatManager scripts

[real ingot]

ok let's just do it like this

go here in the PlayerController

[keen plover]

okay

[real ingot]

after if(photonView.isMine) do this

so do if(chatinputfield.isfocused) {
// Leave it empty
}

else {
CheckInput();
}

[keen plover]

oh wait one sec

i did something wrong now i put it correct like u said and no error

i will try that now wait

okay now its fixed but i will try it out now with 2 players so i can check is it working propertly

[real ingot]

it should work

[keen plover]

It works thank you so much

[real ingot]

np

[real ingot]

Hi!
I got 2 button, one for startHost and second one for startClient. These buttons and script is in another scene where there's no networkManager. How do I load the scene with the networkManager and call the startClient or startHost there?

[candid ginkgo]

I personnally have a "Setup" scene where I have my NetworkManager and other gameobjects that I want to keep through my scenes and use DontDestroyOnLoad. Then I load my other scene that I want the user to interact with by doing ```csharp
public class SceneLoaderManager : MonoBehaviour
{
[SerializeField] private string sceneName = "SampleScene";

void Start()
{
    StartCoroutine(LoadScene());
}

IEnumerator LoadScene()
{
    yield return new WaitUntil(() => NetworkManager.Singleton != null);
    SceneManager.LoadScene(sceneName);
}

}

[candid ginkgo]

sorry forgot to ping

[real ingot]

how do you put gameobjects in the dontdestroyonload?

[candid ginkgo]

GameObject thingy;
DontDestroyOnLoad(thingy);

[real ingot]

thanks

I'll try it out

[candid ginkgo]

btw if you are using unity's NetworkManager I'm pretty sure it automatically gets added to DontDestroyOnLoad

like if you go into play mode in a scene where you have it you should see it get moved to the DontDestroyOnLoad scene like that

[real ingot]

oh yeah I forgot it's automatic

[candid ginkgo]

welp still good to know how to add objects to the dontdestroyonload if you need it for other things haha

[real ingot]

true

but how am I going to add the player and the prefabs into the networkmanager when it's in another scene?

wait

no shit

nvm

I'm stupid

ignore what I just said

[candid ginkgo]

np lol

[real ingot]

that's embarrassing

[real ingot]

it spawns the player in the scene I ran the coroutine thought

[candid ginkgo]

where do you want the player to spawn ?

[real ingot]

in the scene that gets loaded

[candid ginkgo]

Do you use the component's parameter to spawn the player or is it done through script ?

[real ingot]

component. Is that the reason?

[candid ginkgo]

It might be because I'm not sure if it takes into account the scene changes

lemme check how I handle mine

[real ingot]

wait then how do I do it through script. NetworkManager.Singleton.playerprefab?

[candid ginkgo]

public class PlayerSpawner : NetworkBehaviour
{
    [SerializeField] private GameObject playerPrefab;

    private void Start()
    {
        DontDestroyOnLoad(gameObject);
    }

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

    private void SceneLoaded(string sceneName, LoadSceneMode loadSceneMode, List<ulong> clientsCompleted, List<ulong> clientsTimedOut)
    {
        if(IsHost && sceneName == "GameplayTest")
        {
            foreach(ulong id in clientsCompleted)
            {
                GameObject player = Instantiate(playerPrefab);
                player.GetComponent<NetworkObject>().SpawnAsPlayerObject(id, true);
            }
        }
    }
}

basically you check for the onsceneloaded event and instantiate them as player objects when the event is called

or more like you instantiate them locally and then spawn them on the network as player objects

also if you already have a lobby of players that is connected you should switch scenes using csharp if(NetworkManager.Singleton.IsHost) NetworkManager.Singleton.SceneManager.LoadScene(sceneToLoadOnStart, LoadSceneMode.Single);

That way it loads the scene for all players

but double check if scene management is enabled before on your networkmanager

[real ingot]

idk what I'm doing wrong

wait

now it works

thanks

[candid ginkgo]

👍

[real ingot]

the client doesn't load up

[candid ginkgo]

oh

[real ingot]

do I have to do isClient in there

[candid ginkgo]

by that do you mean the player doesn't spawn or does it just not load the scene ?

[real ingot]

no the host player loads up but the clients player don't

[candid ginkgo]

are the methods called by buttons from the same scene ?

[real ingot]

yeah

the buttons are in a canvas in the same scene where the spawner is and network manager

do I have to remove the player from the networkprefabs?

[candid ginkgo]

no I don't think thats where the problem comes from

does your InGame scene have those buttons ?

[keen plover]

Does anyone know how to fix this error: The observed monobehaviour (Bullet01(Clone)) of this PhotonView does not implement OnPhotonSerializeView()!

[real ingot]

no

I got the mainmenu scene and the ingame scene

the mainmenu holds all the buttons and functions to go to inGame scene

like the spawner and spawnnetwork

[candid ginkgo]

I would say maybe try separating the spawning of the player and the switching of the scene

like have 2 buttons, that call StartClient and StartHost

and a third button that only has ```csharp
if(NetworkManager.Singleton.IsHost)
NetworkManager.Singleton.SceneManager.LoadScene(sceneToLoadOnStart, LoadSceneMode.Single);

that way only the host can start the scene

[candid ginkgo]

and also this

[real ingot]

It's true on default

[candid ginkgo]

oh ok

[real ingot]

I third button?

why?

why do I need to startHost and startClient on a client button?

[candid ginkgo]

no I meant have 3 buttons total

[real ingot]

Host, client, server?

[candid ginkgo]

host, client, start game

to check what is causing the error

[real ingot]

ah

ok

something like this

oh wait I need to remove the isHost?

[candid ginkgo]

you can I'm pretty sure it should work still

but also

remoev the 3 line from the startclientscene and starthostscene methods

the point of using ```csharp
NetworkManager.Singleton.SceneManager.LoadScene(sceneToLoadOnStart, LoadSceneMode.Single);

[keen plover]

Does anyone know how to fix this error: The observed monobehaviour (Bullet01(Clone)) of this PhotonView does not implement OnPhotonSerializeView()!

[candid ginkgo]

sorry I never used photon

[candid ginkgo]

yeah that looks ok

[real ingot]

Well I pressed the host button and then the start game. Switched to another player and pressed start game but it throws an error

if that's what I had to do

[candid ginkgo]

Was the player you pressed the button with registered as a client ?

In order it should be start host->start client->start game

also are your clients connected to the host ?

[real ingot]

ok so the first player I did host client and start player

it loaded up

but the second one I do client and start player

it throws me an error

[candid ginkgo]

If you do
-> player 1 presses start host
-> player 2 presses start client
-> either players press start game
Does it work ?

[real ingot]

yeah that worked

it's just that it started both games when I pressed one button

which probably means I gotta do if(!isOwner) return;

[candid ginkgo]

do you want them to start separately ?

[real ingot]

ok so imagine the server is already hosted and there and I just want to start the game and join it

that's it

I'm not making a matchmaking game

[candid ginkgo]

Ohhhhh ok I get it

[real ingot]

I want so that you could join a server where people are already playing something like that you know?

[candid ginkgo]

Ok so I'm NOT experienced enought to give you a solution for that but from what I found online

https://forum.unity.com/threads/players-in-different-scenes.1265684/

If you untick the scene management from the networkManager it might help

[real ingot]

wait

ok so you know gta V right?

like online

the server is already hosted

you press a few buttons and you joined the server

all players are in there

[candid ginkgo]

yeah I got that you want players to dynamically join and leave. What I think you can do for that is untick scene management so that it stops synchronizing the scenes

[real ingot]

like you press Start Game in the main menu and you are in the game / server

oh

which way should I start the game now cause it throws an error now and on the client side you can't press start game only server can. Do I have to go back the way the code was before?

[real ingot]

I was a little confused the stuff didn't work

[candid ginkgo]

Yeah maybe using NetworkManager.Singleton.SceneManager.LoadScene(sceneToLoadOnStart, LoadSceneMode.Single);
breaks everything if scene management is unticked

[real ingot]

yep

it's cause of that

[candid ginkgo]

the problem is that the solution I gave you uses its onLoadEventComplete to spawn the players and I'm not sure if it gets called by a normal LoadScene

I guess you'd have to find a way to get the list of playerIds from the network manager when SceneManager.sceneLoaded is called

and then spawn as player objects on the network using their ids

[real ingot]

ok I'll see

[real ingot]

ah so I have to put the scenemanager back on

[candid ginkgo]

yeah I think so

sorry if I confused you I didn't understand you were trying to have something dynamic like that

[real ingot]

nah it's cool

still learning

[candid ginkgo]

same here haha

[real ingot]

still learning networking. It ain't an easy thing

[candid ginkgo]

ikr I've been banging my head against the wall for the past 2 weeks or so trying to make a player controller

[real ingot]

like movement or something?

[candid ginkgo]

yeah trying to make a third person character with wallrunning and a bunch of stuff but it's hard

[real ingot]

I got like 30 unity forums tabs open on google

[candid ginkgo]

lmao

[real ingot]

ah. I did the movement easily

wallrunning is a little something else

[candid ginkgo]

the hardest part so far for me has been understanding what is supposed to happen on the server and what is supposed to happen on the clients

like since I'm using raycasts to check for walls I have no idea if those are supposed to be done client side or server side

or if either work

[real ingot]

I include to the server like visuals so that people would be able to see me instead of including the camera or something.

but I understand you

There's too many things to think about

[candid ginkgo]

welp gonna have to leave for a bit so hope you get your scene loading problem sorted 👍

[real ingot]

yeah I hope it ain't going to take a few days

[vital thicket]

quick question, "lan" style games, like host server and players can login to server and play together, best approach? also is it important to start making game right away with networking for this option or it can be added later?

[nocturne vapor]

it can be added later but that is a nightmare
how to do it is pretty much the getting started part of the docs, which relies on client host connections

[vital thicket]

so it would be better to start with it right away while building? also, it can be online host, not just "owner" on local, but concept is like LAN system, not live service thingy

[real ingot]

do networking just when you start making your game. I made a big mistake by making a lot of contents in the game and then networking. I was forced to make a new scene and rework everything

[sharp axle]

Yea. Otherwise you will end rewriting a bunch of systems to make them netowrk compatible

[vital thicket]

alright, thats what i wanted to know, i know networking is PITA but.. any suggestion on network modes, whats best to go, whats not to do? is Mirror solid to start with or to use unity networking? or something else?

[real ingot]

I just came back and I realised that it already is doing what you explained earlier in the spawners script.

you probably meant that I have to get the player that pressed the start game button and instantiate his playerPrefab

[keen plover]

Does anyone know how to fix this error: The observed monobehaviour (Bullet01(Clone)) of this PhotonView does not implement OnPhotonSerializeView()!

[sharp axle]

I don't use Photon but it sounds like you need to implement OnPhotonSerializeView

[candid ginkgo]

idk if a player can instantiate his own player prefab

The server might need to be the one that does it so that it gets synchronized

[sharp axle]

You'll need to make sure that this is only running on the Server/Host

[real ingot]

it is

[real ingot]

Ahhh that's what you mean

ah shit. This only spawns all the players at the same time then

that's a problem

[candid ginkgo]

What I think you could do is have a subscription to the SceneManager.sceneLoaded

this should only be client side since it's not the NetworkManager.Singleton.SceneManager

and then you send a ServerRPC that makes the server instantiate the player prefab and makes the client that sent the rpc the owner

[real ingot]

I see

[candid ginkgo]

to get the clientId I found this on the docs csharp [ServerRpc(RequireOwnership = false)] public void MyGlobalServerRpc(ServerRpcParams serverRpcParams = default) { var clientId = serverRpcParams.Receive.SenderClientId;

[real ingot]

I understand a hunch of that but since I'm a beginner at networking I'm not quite sure

[real ingot]

huh'

ok

[candid ginkgo]

hold on Imma write a quick mockup script and you tell me if you get what I'm trying to say

[sharp axle]

You should be subscribing to OnSceneEvent if you want to wait to load all the players agter they are in the new scene
https://docs-multiplayer.unity3d.com/netcode/current/basics/scenemanagement/scene-events/#tracking-event-notifications-onsceneevent

[candid ginkgo]

he wants the players to hop in and out of his scene dynamically

[real ingot]

I'm not aiming for a matchmaking

[sharp axle]

I gotcha. There is no real support for that kind of drop in drop out multiplayer

Maybe if you load scenes additively? You would need to setup some kind of custom scene management

[candid ginkgo]

@real ingot something like that might work ```csharp
public class TestScriptWoohoo : NetworkBehaviour
{
GameObject playerPrefab;

private void OnEnable()
{
    SceneManager.sceneLoaded += OnSceneLoaded;
}

private void OnDisable()
{
    SceneManager.sceneLoaded -= OnSceneLoaded;
}

void OnSceneLoaded(Scene scene, LoadSceneMode mode)
{
    // this is called on the client
    if(scene.name == "TheNameOfTheSceneWhereYouWantToSpawnPlayers")
    {
        if (!IsServer)
        {
            // this is called on the client
            // we need to tell the server that we joined the scene
            PlayerJoinedSceneServerRPC();
        }
    }
}

[ServerRpc(RequireOwnership = false)]
public void PlayerJoinedSceneServerRPC(ServerRpcParams serverRpcParams = default)
{
    // this is called on the server
    ulong id = serverRpcParams.Receive.SenderClientId;

    GameObject player = Instantiate(playerPrefab);
    player.GetComponent<NetworkObject>().SpawnAsPlayerObject(id, true);
    // since the prefab is a NetworkObject, it will be spawned on the clients automatically (hopefully)
}

}

[drifting plaza]

If one client updates a static variable, will another client running the same script automaticaly receive the updated version of that static variable?

[drifting plaza]

eh nvm its not that big

[real ingot]

Ok I'll see

[real ingot]

does it really have to be server? shouldn

shouldn't it be IsHost?

[candid ginkgo]

isserver returns true for host I'm pretty sure

[real ingot]

ah ok

[candid ginkgo]

Ah bit now that I think about it that might be a problem in our case

[drifting plaza]

do you guys know how this works?

[sharp axle]

It does not unless that static variable is also a network variable

[drifting plaza]

phew, okay, thanks

[candid ginkgo]

since we also want the host to spawn his player you might need to replace it with (isClient)

[real ingot]

well not until I get a server

[candid ginkgo]

afaik a host returns true for both isclient and isserver but I can't find anything that explain it clearly

[real ingot]

so when I get a server I just have to change it to !IsServer

[real ingot]

it doesn't

as much as I remember

[sharp axle]

Host is a client and a server

[real ingot]

oh really?

dang

[candid ginkgo]

in that case definetly replace the if by a isClient

to make sure that only clients call the ServerRPC

so far I've been only using isclient and isserver unless I need to do something that is very specific to having a host

[real ingot]

oh wait

I need to do dontdestroyobject

onload

[candid ginkgo]

yeah probably

[real ingot]

{
    [SerializeField] private GameObject playerPrefab;

    void Start()
    {
        DontDestroyOnLoad(gameObject);
    }

    private void OnEnable()
    {
        SceneManager.sceneLoaded += OnSceneLoaded;
    }

    private void OnDisable()
    {
        SceneManager.sceneLoaded -= OnSceneLoaded;
    }

    void OnSceneLoaded(Scene scene, LoadSceneMode mode)
    {
        // this is called on the client
        if (scene.name == "InGame")
        {
            if (!IsClient)
            {
                // this is called on the client
                // we need to tell the server that we joined the scene
                PlayerJoinedSceneServerRPC();
            }
        }
    }

    [ServerRpc(RequireOwnership = false)]
    public void PlayerJoinedSceneServerRPC(ServerRpcParams serverRpcParams = default)
    {
        // this is called on the server
        ulong id = serverRpcParams.Receive.SenderClientId;

        GameObject player = Instantiate(playerPrefab);
        player.GetComponent<NetworkObject>().SpawnAsPlayerObject(id, true);
        // since the prefab is a NetworkObject, it will be spawned on the clients automatically (hopefully)
    }
}```

{
    public void StartHost()
    {
        StartCoroutine(StartHostScene());
    }

    public void StartClient()
    {
        StartCoroutine(StartClientScene());
    }

    public void StartGame()
    {
        StartCoroutine(StartGameScene());
    }

    IEnumerator StartHostScene()
    {
        yield return new WaitUntil(() => NetworkManager.Singleton != null);
        NetworkManager.Singleton.StartHost();
    }

    IEnumerator StartClientScene()
    {
        yield return new WaitUntil(() => NetworkManager.Singleton != null);
        NetworkManager.Singleton.StartClient();
    }

    IEnumerator StartGameScene()
    {
        yield return new WaitUntil(() => NetworkManager.Singleton != null);
        NetworkManager.Singleton.SceneManager.LoadScene("InGame", LoadSceneMode.Single);
    }
}```

idk about the startnetwork though.

Should I leave as is?

oh and shouldn't if(!IsClient) be if(IsClient)?

[real ingot]

It doesn't load the player btw

[candid ginkgo]

The startnetwork still uses the NetworkManager.Singleton.SceneManager

but I'm pretty sure if you don't want the scenes to be synced you should untick the scene management from the network manager

and if you untick it I don't think you can use NetworkManager.Singleton.SceneManager

you should replace it with a normal loadscene

[real ingot]

isn't just simply doing loadscene gonna put me in an empty scene where no players exist?

[candid ginkgo]

thats where the ServerRPC comes in

[real ingot]

ah ok

[candid ginkgo]

ideally it should load the scene and then spawn the player

[real ingot]

ok so the scene loads up for both host and client separately which is good but the players don't spawn

this doesn't get called at all

[real ingot]

After the player 1 presses host and start game it only goes past this line if (scene.name == "InGame") and player 2 when I press client it throws me an error

[candid ginkgo]

check your network prefab list it might have cleared the prefab

happened to me once

[real ingot]

it's fine

[candid ginkgo]

darn

[real ingot]

and the list is fine too in the network manager

I've debugged this stuff a little

[candid ginkgo]

wait your calling the serverrpc from the server

it needs to be called from the client

[real ingot]

shiat

this is what got debugged when I hosted and started the game.

[real ingot]

and this is when I did client and start the game on player 2

[real ingot]

and I did !IsServer instead of !IsClient

[real ingot]

oh and after some time the host debugged this

oh wait

[real ingot]

sorry I didn't read

fixed this

the host loaded up but the client didn't

for the client it keeps throwing these errors

unless I don't even need to start client but just press start game

after hosting

[candid ginkgo]

idk it seems to react weirdly

do you have code that is trying to destroy a networkobject on the clientside ?

[real ingot]

but if I do that it loads both players in like it should but it doesn't show the other players in the scene

[real ingot]

I shouldn't

[real ingot]

that only happens when I press client and then start game

that like spawns the player but in the mainmenu scene

[candid ginkgo]

I think the expected result should be something like that for now but the errors are weird

basically

[real ingot]

but when I host and start game it spawns the player in the right scene and everything works fine

[candid ginkgo]

When the host starts the game it should spawn his player on his side and load the scene on his side

then when the clients joins in the main menu it should probably show the characters because they are synced regardless of the scene if I'm not wrong

[real ingot]

start network code: https://paste.ofcode.org/BzFM5c2Xjby27w4W5mWX6c

Spawner code: https://paste.ofcode.org/kFAhNVh5Y2qQYbVFTSivE3

[real ingot]

when I host and press play game. Not just host. I'm assuming you meant the right thing

[candid ginkgo]

yeah mb

I mean I still think there should be a host before you join or else there will be no servers to join

[real ingot]

I recorded a little video to make it a little more clear to whats going on

[real ingot]

yeah I do that

[candid ginkgo]

Well honestly the behaviour you have rn is almost what I think should happen but I have no idea where the error comes from and why it makes it so you can't change scene

like the fact that when you press start client it spawns a player is good because if I'm not wrong that should be the host's player

like if you move him on his side it might even move on the client's side if the errors don't cause it to completely bug out

maybe one of your editor has a prefab that is technically different I'm not sure ?

like if you make a build for the client does it work ?

[real ingot]

yeah it's on the host cause if I simply press client and start game it doesn't really do anything except switch scenes with no player

when I press client when the server is hosted it only spawns the player for the client not for the host

so the host can't see the client

[real ingot]

so doing this isn't gonna do anything

[candid ginkgo]

oh ok

[real ingot]

it doesn't tho find the server

when I press client which is good

it just doesn't switch scenes after I press start game

[candid ginkgo]

Yeah I'm guessing the errors are causing it to sorta crash and it won't let you switch

[real ingot]

OH WAIT

so when I press the client on player 2 when the server is hosted. The player 2 doesn't spawn but it is showing player 1

[candid ginkgo]

yeah thats what I meant by that

[real ingot]

it is moving too when I'm moving on player 1

[candid ginkgo]

to double check during play mode in the networkObject component it should tell you the id of the owner

host should be id 0 (I think)

[real ingot]

yep

it is

both on host and client

[candid ginkgo]

nice that means we're getting close

[real ingot]

aka player 1 and player 2

[candid ginkgo]

problem now is to find out what's causing those errors

cuz I'm guessing their the ones making you unable to switch sscenes

try running from a build from player 2

[real ingot]

you mean host on player 2?

just saying the files and everything is the same on both editors at all times

[candid ginkgo]

oh ok then nvm

[real ingot]

I'm using parrelSync clone manager to do this

immediately after I press client it runs this

and so it doesn't continue

someone had the same issue as me https://forum.unity.com/threads/something-breaks-when-spawning-as-client.1406806/

it might be cause it's not adding the object to the prefab list

to the player list

after I press client and start game it spawns the player in but crashes immediately

I know that cause it shows the 2 listeners debug sometimes for a quarter of a second

when I press client and start game it shows this too. This is a little new

it destroys the spawner script gameobject after pressing client too

[candid ginkgo]

is the playerspawner a networkobject ?

if not maybe making it one might help

[real ingot]

yeah it is

I'll try playing with the networkobject settings

yeah nothing is working

[real ingot]

this line could be the one destroying the spawner. Idk how thought

since it did spawn the player 2 for like a little second and then destroyed the spawner and crashed after I pressed start game

here

[candid ginkgo]

Hopefully it's not an error due to ngo not planning for people to join/leave on the go

honestly I have no clue what could cause this rn

maybe adding the playerspawner to the list of prefabs ?

[real ingot]

I'll see tho I doubt that'll work

[real ingot]

that prevented errors

and stopped the spawner from destroying it self

never mind

[candid ginkgo]

dammit

[real ingot]

this is so frustrating

this just explains how hard networking is

;P

usually the cause of the bugs could be the smallest mistake like forgetting to do something or doing true instead of false on a bool

I really don't see any problem in here

nor else where

I'ma have to think about this for a while. I'm not going to be home tmr for a while so I'll learn a little more networking and try to solve this issue

if you or someone else found a way to fix this please tell me. I'll make sure to debug after I'm back. Unless someone will find a way till tomorrow. It's late for me so I'll take a break

[candid ginkgo]

Yeah I'll look around

[real ingot]

I'll do too

[shrewd junco]

not really, server rpc's run on the server so it wont be able to get the clients input. One thing you can do is use network variables for input, then the server moves everyone based on the networkvariables every frame

[azure crown]

There are no NetworkTransforms in Netcode?

hey guys unity specific things like Random doesn't work when I call a function from the websocket for example the Orange() only prints "Orange" but not "Apple" ```using WebSocketSharp;
using UnityEngine;

{
    ws = new WebSocket("ws://localhost:8080");

[real ingot]

Yo! Can I ask really quickly what does networkmanager.singleton mean. Why does some people do networkmanager.singleton != Null

[shrewd junco]

The singleton pattern is to make sure there is only 1 of an object. Things would break very quickly if you loaded a level, and there was another network manager trying to do its own things. Or even if it doesnt break, you just dont need 2.
The singleton pattern ensures theres one but also gives u a reference to the object through its public field "Singleton". If this didnt exist, you couldnt just do NetworkManager != null because that's just the class name

[sharp axle]

You'll need to check your console for any error messages.

[sharp axle]

To add on to what the others said. Calling networkManager.Shutdown() will also make the Singleton null. So it can also be a way of checking if your manager is still running

[weak plinth]

no errors

[weak plinth]

I got it working after many many hours : ```using WebSocketSharp;
using UnityEngine;

public class WSClient : MonoBehaviour

FishSpawner fishSpawner;

string message;
void Start()
{

    fishSpawner = GetComponent<FishSpawner>();
    ws = new WebSocket("ws://localhost:8080");
    ws.Connect();
    ws.OnMessage += (sender, e) =>
            {
                message = e.Data.ToString();

            };
}

void Update()
{
    if (message is not null)
    {
        fishSpawner.SpawnFish(message.Replace("Spawn fish:", ""));
        message = null;
    }
}

}```

Im having an issue with multiplayer as its my first time doing it and im new to unity, when I join as a second user I can only look up and down and cannot move, the host can move just fine. Im using a youtubers movement script that I changed a bit and a matchmaking script as well. Can anyone help with that? Heres my movement script https://hastebin.com/share/sihilibuwu.csharp, and my other script https://hastebin.com/share/ecigixoqav.csharp

What would be the most cost effective networking solution? I am looking at Photon and play fab at the moment. I plan for ~500 CCU maximum and just want to use multiplayer and maybe a leaderboard for a mobile game. Each lobby would be 2 players

can I ask netcode stuff here ? is it ok ?

[real ingot]

Yeah

[half anvil]

is there a seprate discord server dedicated to netcode ?

[real ingot]

Yes here: https://discord.gg/unity-multiplayer-network

You can ask for help there and here

[molten dragon]

guys what is netcodeObject in netcode
i think the definition of netcodeObject is same as photon networking engine

[austere yacht]

https://docs-multiplayer.unity3d.com/netcode/current/basics/networkobject/

[austere yacht]

To replicate any Netcode aware properties or send/receive RPCs, a GameObject must have a NetworkObject component and at least one NetworkBehaviour component. Any Netcode-related component, such as a NetworkTransform or a NetworkBehaviour with one or more NetworkVariables or RPCs, requires a NetworkObject component on the same relative GameObject (or on a parent of the GameObject in question).

[molten dragon]

i read that , but its same like photo Engine

[austere yacht]

so?

[molten dragon]

can i have old version of unity docs

okay i got it

[vagrant garden]

No it's different. Photon stuff can run in cloud mode. Netcode for GameObjects needs a server / host. And many more differences.

[tidal hemlock]

Someone familiar with Netcode for GOs (specifically network animator) can help with a problem related to animator layers?

I’ve looked up quite a bit and can’t find anything (useful)

[scarlet marlin]

I'm in the early stages of using netcode for gameobjects and have a simple program that works great on local, but I added code to use the SetConnectionData call and simply inputting 127.0.0.1 gets me a "network address invalid" error. Is that supposed to happen if you put that in from that call?

[molten dragon]

the definitions are same

guys what the difference between
this NetworkBehaviour https://docs.unity3d.com/Manual/class-NetworkBehaviour.html
and this NetworkBehaviour https://docs-multiplayer.unity3d.com/netcode/current/basics/networkbehavior/

[tidal hemlock]

Not sure if there are any rules against posting unity discussion questions in the channel but I made a proper one about this ^ in case anyone knows

[sonic lintel]

Hey guys I really really lost I want to build an mmo game, and a competitive game when you have 2-6 plaer in room,
I don't know what network to use, I build a 3 games in photon but I know it's just free to 10 player or something like this, I build my own server using socket in few projects but its dont have any encryption(o reallynot good at encryption),so can you guys help me to decide What to use

[zenith crescent]

ngo or fishnet no if ands or buts about it, since ur already familiar

(netcode for gameobjects)

unity has a lot of lobby features and a bunch of multiplayer tools

integrated for ngo

i came from pun 2 to ngo and i love it

its also a first party solution which makes me happy

@sonic lintel

also very easy to setup dedicated servers with it

[sonic lintel]

OK ty very much!

You have any good tutorials to start with ?

[zenith crescent]

https://www.youtube.com/watch?v=3yuBOB3VrCk&t=2617s&ab_channel=CodeMonkey this is a great tutorial my first one i watched

it got me into it pretty quick

[sonic lintel]

OK man ty so much I really got lost with all the network, ty !

[zenith crescent]

np i have been researching solutions for the past month it drove me crazy but ended up on netcode for alot of reasons

its great for games with under 20 people

and theres netcode for entities that can handle alot more

and there pretty similar so start with netcode for gameobjects for under 10-20 player games

[sonic lintel]

Got it ty !

It's can handle an mmo right?

[zenith crescent]

yea definitely

[half anvil]

how should a synchornized player movement be programmed ?

should it be like player moves and then there is [Command] function that sends the coordinates of the player which is then told to all the clients ?

[zenith crescent]

i cant find any good sources on how to implement client prediction for NGO i followed one tutorial but it had alot of issues does anyone know where i can find good resources?

[austere yacht]

You should not expect to find tutorials for one of the more advanced and nongeneric problems in networking. Typically you’d have to make your own decisions based on understanding the principles behind it. Your netcode framework doesn’t (shouldn’t) matter. Theory here: https://github.com/ThusSpokeNomad/GameNetworkingResources

[real ingot]

Use network transform. That'll do it. I prefer using client network transform. Assign the component to the object that moves or changes the size and tick off the transform position, rotation, scale axis that isn't needed.

[half anvil]

hey I am not able to move as a client

you wanna see da code ?

[real ingot]

Client network transform doesn't have a seperate script so you'll have to go to unity website and find the code there

[real ingot]

Show it

[half anvil]

using System.Collections;
using System.Collections.Generic;
using Unity.Netcode;
using UnityEditor.UI;
using UnityEngine;

public class playerMovement : NetworkBehaviour
{
    private Rigidbody2D rb;
    private float speed = 20f;
    // Start is called before the first frame update
    void Start()
    {
        rb = GetComponent<Rigidbody2D>();
    }

    // Update is called once per frame
    void Update()
    {
        

        if (!IsOwner) {
            return;
         };
        float moveHorizontal = Input.GetAxis("Horizontal");
        float moveVertical = Input.GetAxis("Vertical");

        // Calculate movement vector
        Vector2 movement = new Vector2(moveHorizontal, moveVertical) * speed;

        // Apply movement to the Rigidbody
        rb.velocity = movement;
    }

}

[half anvil]

here

does this look okay ?

[half anvil]

wdym

[real ingot]

https://docs-multiplayer.unity3d.com/netcode/1.0.0/components/networktransform/

Scroll down to client network transform and copy all the code in there

Create a script and call it ClientNetworkTransform

Then paste all the code inside it and make sure the name is right

Then assign the script to the player.

The player will move for all clients now just make sure to tick off all unnecessary syncing axis in the component to prevent lag

You can immediately tick off position, rotation, scale z axis since your game is a 2D

[half anvil]

hey is there a ClientNetworkTransform already built it lemme check

[real ingot]

No there is no clientNetworkTransform built in

[half anvil]

oooohhhh

[real ingot]

Use this link and follow the stuff I wrote

[real ingot]

Do this in the website

The component should look like this

Leave the threshold and configuration alone

You don't really need to change anything in there

[real ingot]

Syncing is what you need yo change

[half anvil]

so I should remove network transform and add client transform

?

also doesnt rigid body rely on network transform ?

rigid body 2d

@real ingot thanks a lot man it is working but I dont understand how the script works but i dont understand how the network transform works either

I mean should I know that stuff ?

[real ingot]

Idk what you mean about that

[half anvil]

I am just saying that I dont understand how network transform or client transform works

[real ingot]

For rigidbody you need a component called network rigidbody I believe so assign that to your player that holds the rigidbody and the physics related movement like falling is going to be smooth

[half anvil]

it is too complicated for me network transform and client transform

[real ingot]

Now since it's in 2D I'm not sure how it works and if you really need it or not since I only work on 3D games

[half anvil]

to understand their working or code

[real ingot]

It's simply a thing that you need so that your movement would be sent to the server and then to all the clients

[real ingot]

I was talking about rigidbody network there

[half anvil]

so it is something like it tells the server and the server tell the clients like all the clients

[real ingot]

Yeah sort of

For further info go here https://docs-multiplayer.unity3d.com/netcode/current/components/networktransform/

It'll explain it better then I will

[half anvil]

hey it does not tell differences between network transform and client transform clearly

[real ingot]

This website will tell you

Sorry

"NetworkTransform always synchronizes positions from the server to the clients and position changes on the clients aren't allowed. Netcode for GameObjects comes with a sample containing a ClientNetworkTransform. This transform synchronizes the position of the owner client to the server and all other client allowing for client authoritative gameplay."

Here

That'll explain the difference

[half anvil]

how is movement synchronized when using client transfrom and not in network transform

I dont understand

oh position changes on client arent allowed

int network transform

is that y ?

[real ingot]

You need to read fully before asking questions or arguing

[real ingot]

Idk

You don't need to know how does ClientNetworkTransform code works

All you need to know is the difference and the settings inside it

[half anvil]

I just wanna know the difference

[real ingot]

This explains all the difference

[half anvil]

yeah I am seeing

[real ingot]

Servers has this problem with permissions. So we use clientNetworkTransform to send the movement to other clients without any problems

[half anvil]

yeah see this NetworkTransform always synchronizes positions from the server to the clients and position changes on the clients aren't allowed. Netcode for GameObjects comes with a sample containing a ClientNetworkTransform. This transform synchronizes the position of the owner client to the server and all other client allowing for client authoritative gameplay.

[real ingot]

Since I'm pretty new at networking too I can't tell you if this is right or not so yeah I'm trying my best lol

[half anvil]

I dont know if this is safe or not but it works

becuase synchronizes the position of the owner client to the server and all other client allowing for client authoritative gameplay

[real ingot]

It is safe and original m

It's made by unity and most people are using this

[half anvil]

ok

[real ingot]

The normal NetworkTransform I'm not really sure when you should use it

[half anvil]

i think we need to do manually what clientTransform does in networkTransform I maybe wrong

[real ingot]

Everything is the same in the inspector for both

It just turns a method bool to true to give perms and that's it

[half anvil]

ohhh

[half anvil]

do you know how the code works ?

[real ingot]

It's the way the code is written I'm not on my pc so I'm just explaining all this from what I remember

[half anvil]

you seem like an interesting fellow can you send me the link of your itch page

[astral tree]

I am making a meeting application using 3D avatars and what I am trying to do is open a data channel between two peers using Unity's WebRTC package.
The data I am sending are blendshape values predicted by some AI model, so basically a list of integers.
The simulation needs to be realtime and the data should be transmitted as fast as possible.
However I am not sure what is the best configuration for the data channel to be as fast as possible
I tried playing with the maxPacketLifeTime but I can't see any difference.
Has anyone worked on something similar ?

[real ingot]

I don't have that

[shrewd junco]

It's technically not safe out of the box. It shouldnt be used alone in games where anything really matters (like highscores). I believe reading that's why it's not included in just the ngo package (yet included in the samples still).

Yet if it's just a game between friends, you can rely on friends not hacking in each others games for an unfair advantage

[real ingot]

No one really said that it was bad before so I just assumed that it was safe but since it wasn't isn't in the ngo package I was a little hesitant to say that it was safe

[shrewd junco]

It's not that it's bad cause it is just a network transform without server authority. there are times where u could use it with no downside. You just really wouldnt want it when players can be interact with random people online, whether that be an online leaderboard, some trading system, or just joining each other

If I had a game that didnt use physics, I would LOVE to use it. Because rn I'm suffering with input lag

[real ingot]

Wait so should I use NetworkTransform instead client? If I want to prevent hackers?

[shrewd junco]

Depends on the scope of your game. if your game is intended to be between random people then yes probably. Otherwise people could just ruin the experience for others unless you manage to get an insanely good anti cheat.. which I dont know much about.
But even with a network transform (aka swapping to server authoritative), someone hosting the game could still be the hacker. Then you'd have to look at other solutions like hosting your own server etc etc. But this is a far less worrisome case

And the last part was me just saying you wont ever fully deal with hackers, so decide what part you want to actually deal with

[real ingot]

Ok

[sacred prawn]

anyone who managed to create a version of the xr socket from the xr toolkit that can be used over network either with normcore or photon? I made some attempts in the past but never got anywhere.

[half anvil]

Ok buy how would u synchronize movement with network transform ?

[real ingot]

You'll have to do some coding to do that

[half anvil]

I know but I am not skilled enough

[real ingot]

Client network transform as much as I know now just gives access to hackers changing the way you move without a problem cause the server isn't interrupting. Now with network transform you'll have to do checks and passes I believe but idk

[real ingot]

Google bro

[half anvil]

Ok I ll try do you use only unity or some other engine as well

[real ingot]

Only unity. Why?

[half anvil]

ok do you do internship or job ?

[real ingot]

I work on my own game m8

I'm not working for anyone

[half anvil]

cool I ll do some googling

about network transform

[real ingot]

Why were you asking those questions tho?

[half anvil]

idk you seemed interesting

[half anvil]

where do you host live game dev projects ?

like I have a itch page

and github for code

[real ingot]

Don't really get that. Servers? Where do I save my project files?

[half anvil]

like you can make a web file of your game and post your game online so others can see

just like playstore

[real ingot]

Ah that's what you mean

I'm not doing that

I'm going to post my game on steam

[half anvil]

oh thats even better a finished product

[real ingot]

No bro. I don't have it there yet but it'll be there in a year or so maybe

[half anvil]

r u using a pc or laptop rn ?

[real ingot]

Not using anything I'm on a vacation. For coding I use a pc but I'm planning on getting a laptop sooner or later

[shrewd junco]

is it a network object? im confused what you mean by replicate

maybe you could just send an rpc to all clients saying to disable it, if you dont want to despawn the entire object

you dont neccessarily need to send the object reference, if each player grabs the same reference on awake/start

really depends what this is though

i would have all the weapons stored as some ID -> gameobject reference, client clicks a weapon, sends a server rpc to equip that ID, server sends a client rpc (to everyone) saying equip [X] on that player. Each player looks it up in their own dictionary

the client rpc should take care of that for you

nah im saying like everyone has a reference that "sword" or [0] points to the gameobject, then "bow" or [1] points to gameobject2 for everyone

it really should just be fine to have these mostly setup from the inspector

id say a bigger problem would be either getting a serialized dictionary, or converting that inspector data to a dictionary

[weary tangle]

So there is a single player drag racing game for mobile. I want to change it to multiplayer. The basic scripts would remain unchanged or would they need to be abrogated ?

[zenith crescent]

pretty simple question i have client prediction implemented and it works great but the host isnt calling ProcessSimulatedMovement for other clients but the clients are calling it for eachother, its like the host isnt calling processsimulatedplayermovement for other clients so everyone looks choppy on the host i tried all combinations of isowner ishost islocalplayer or isclient im confused

            _playerMovement.ProcessLocalPlayerMovement(movementInput, lookInput);
        }
        else{
            _playerMovement.ProcessSimulatedPlayerMovement();
        }```

[sharp axle]

Depends on how you built the single player, but most likely you'll end up rewriting most of the game

[sharp axle]

You'll need to put a breakpoint there in the code to see why thsts not running. If this is on the player prefab, then the remote players should run the simulated movement function

[nocturne vapor]

here a really easy way to do this, have a parent oject you call weaponmanager of the wepons. When you enable/disable one you loop thorugh the child objects to see if the weapon is what you want to enable/disable, if it is, send a rpc with that child index

[lean anchor]

@spring crane basically i just want a non ip sharing multiplayer game that i can make for free. im already familiar with photon. does it work with webgl?

[spring crane]

You should confirm this for every individual product, as the capabilities (and requirements) can differ a lot depending on what they do. At least PUN and Fusion do support WebGL.

[lean anchor]

ok, so i should look into the photon PUN (solution im planning to use) documentation?

[spring crane]

Yea you should see platform requirements mentioned somewhere. Note that PUN is now a legacy product, superseded by Fusion

[lean anchor]

what does legacy product mean?

[spring crane]

PUN Classic (v1), PUN 2 and Bolt are in maintenance mode. PUN 2 will support Unity 2019 to 2022, but no new features will be added. Of course all your PUN & Bolt projects will continue to work and run with the known performance in the future. For any upcoming or new projects: please switch to Photon Fusion or Quantum.

[lean anchor]

oh ok i will look into these

[nova linden]

how much does a network transform taker per second in bytes ?

[sly pawn]

That question doesn't really make sense

If ur asking about how long a message takes, it really depends on distance and signal

[sharp axle]

If you mean NGO, nothing is transmitted unless the object is moving

[nova linden]

but if its moving, i want to know arroun dhow many objects i can have moving at the same time

[sharp axle]

There is no hard limit. Thousands if you want. You will need to use The Network Profiler to gauge those metrics

[nova linden]

is there atleast a rule of thumb how much the average persons network conection can handle without creating insane lag

[real ingot]

yo. You got anything? Cause I got no clue

[sharp axle]

for an average game, the host is sending 5-10 kbps per client. The average user in the US has 3Mbps connection.

[nova linden]

okay so i dont have to worry about that part

[candid ginkgo]

I saw that there was a "active scene" checkbox on the networkobject component which you could try to play around with but other than that same here no clue

Maybe make a post on the forums and hope someone with more experience has a fix

Or if it's a problem with ngo itself it gets noticed by a unity dev

[real ingot]

yeah I was planning to do that if we aren't going to make any progress

[sand talon]

Hi, i'm working on a Team Based PVP game and am kinda at a halt. I finished the game mechanics, they are all networked and work fine as is, tho now i need to introduce a round or match system, where the game loads everyone into a match and does all the background stuff, like checking a teams score, or counting the clock etc. Where would i start with an object like that? What is necesary for something like that...? Any ideas help!

[real ingot]

Use unity gaming service multiplay matchmaking server

[sand talon]

Does that work with Photon?

[sharp axle]

It can yea.

[sand talon]

what does the matchmaking server do?

[sharp axle]

https://docs.unity.com/matchmaker/en-us/manual/matchmaker-overview

[sand talon]

that seems a little overcomplicated... imma try to make a barebones system that works for now!

still thanks for the suggestion!

[real ingot]

I've am messing around a little trying to get more warnings and errors to understand what's going on. I got this warning

Well this happened only cause I placed the loadScene in the startClient it self

and it caused it to not even startclient for some reason

just load scene and that's it

I just commented everything out and left the DontDestroyOnLoad(gameObject); on start in the spawner script and it actually still gave me the same errors after I press start client

kinda obvious

idk man

but the host is completely unaffected which frustrates me

it could be cause the spawner object is owned by the host

that's probably the reason

unless that's how it should be like

oh and the client seem to be going for the OwnerClientId 0 instead of 1 as much as I remember

Now I just think that there might be a problem with NGO it self or something is wrong with the start network start client or it's the spawner object it self the networkobject

[candid ginkgo]

yeah I guess that might just be something they didn't plan ngo to be used for

which still seems weird to me because it's not that uncommon for games to have player's join a game in the middle

I guess it's just one of the downsides of ngo being relatively recent

idk if that would change anything but maybe you could try changing the scene first and then joining with the client

just to check if the problem comes from the client connecting in general or just him connecting with scenes not synchronized

[shrewd junco]

What was the issue if you dont mind pointing me to where you described the issue?

[real ingot]

scroll up

[real ingot]

.

[candid ginkgo]

to sum it up he's trying to make a system where player's can join in/out of a lobby mid-game but getting errors which we can't understand

[shrewd junco]

from what i see above and in the video, it seems like some things just arent synced across editors like the network prefab list. That warning u got in the video about network prefab list not being initialized was an error in ngo 1.4.0 but was fixed i believe in 1.5.1

as for the 2 listeners thing being printed, thats (probably) because you have 2 cameras in the scene. You simply just need to disable a camera if you arent the owner of it
And the destroy one im not entirely sure, i would have to see more of the code to understand what was being destroyed

[real ingot]

the thing is I don't. What I was guessing is the second player (client) connected for a second and his prefab (player) got spawned and then destroyed

[candid ginkgo]

yeah I guess it might still be helpful to make a build to be 100% sure it's not caused by the prefab list

[real ingot]

cause there's only 1 player in there with 1 listener

[shrewd junco]

i would really just test this with cubes to start. At least that way u can narrow down where the error is

but you gotta make sure you add everything that spawns on the network to the network prefab list

[real ingot]

I did

[shrewd junco]

I think sometimes mine dont save fully either, so what I do is just check the prefab list on both editors, or ill move something in the scene (so i can save) and it should prompt the 2nd editor to reload

but i only really had that happen twice

[real ingot]

do I need to have the spawner in the prefab list?

[candid ginkgo]

might help

[shrewd junco]

if it just exists in the scene then maybe not

although idk what this spawner is really doing

[real ingot]

so I did this and it only printed "InGame" in console

[shrewd junco]

i believe this is probably running more than you think, but is there any reason you are doing this instead of using the network managers spawn feature?

[real ingot]

so it just sees the client as not a client

[shrewd junco]

you just plug in the prefab and itll spawn players for you

[candid ginkgo]

the scenes aren't synced so the idea was that the player can have joined the host while still being in the menu and it only spawns the player object when he loads the ingame scene

[candid ginkgo]

oh yeah that makes sense since the isclient isn't true when the onsceneloaded event is called

[shrewd junco]

you should still be able to just use the network manager spawn but instead just load the scene for the player after the host does

[candid ginkgo]

do you mean the onnetworkspawn event ?

[shrewd junco]

i mean just letting the network manager spawn the player still

[candid ginkgo]

it does in the PlayerJoinedSceneServerRPC doesn't it ?

[shrewd junco]

no because is client isnt gonna be true at this point

it might be running too early

[candid ginkgo]

do you think replacing the subscription to the sceneloaded event in the OnEnable by OnNetworkSpawn would help ?

[real ingot]

how does that work?

[shrewd junco]

i think itd be better if the server itself just handled it, but give me a moment to test something before i suggest this

[candid ginkgo]

Also afaik the problem occured when the client connected to the host so we never got to the point where the onsceneloaded event was called on the client

[shrewd junco]

given that the scene is basically empty, its probably all running instantly

[real ingot]

not even the onSceneLoaded() gets called when I try to connect to the host as a client

nothing prints out

[candid ginkgo]

which makes sense so far since when you pressed on the button it didn't switch scenes so it doesn't call the method

just to be 1000000% certain I think you should try running the client from a build if you haven't yet

[real ingot]

plus the players spawn in the main menu after pressing client so pressing the client and then the start game is a little bad

[candid ginkgo]

because this error is very suspicious

[shrewd junco]

that error just means the prefab list isnt updated

[real ingot]

same thing

[shrewd junco]

can you screenshot your network manager and prefab lists

[real ingot]

it's the same thing everywhere

[candid ginkgo]

still can't press start game ?

[real ingot]

I pressed client

it showed the other player

then pressed the start game and it just froze cause it tried to switch scenes

[candid ginkgo]

darn

[real ingot]

ok

[shrewd junco]

and the other client has the same 1 object, and nothing assigned in Player prefab right?

[real ingot]

yep

same object for the players

only 1 prefab for the players

no player prefab assigned, only for the spawner script

[shrewd junco]

is the host itself spawning by the same code? because the OnSceneLoaded part i imagine is trying to run before you can even press the host button

[real ingot]

.

That'll answer the question

I hope

[candid ginkgo]

to my understanding in order it should be : host gets created -> he starts the game which switches scene which spawns his player -> client gets created -> he switches scene which should spawn his player

[real ingot]

yeah

[candid ginkgo]

but rn it gets stuck at step 3

[real ingot]

Player1: Host, start game

player2: Client, start game

now ofcourse in the future I'll host a dedicated server so the host button ain't going to be there no more plus I gotta think of a way to make it so that it would connect as a client to the server and change scenes in one click instead of 2

[candid ginkgo]

did you try enabling active scene sync or playing around with these

I quickly read the docs but they didn't go too much into detail as to how that worked but maybe it could help

[real ingot]

on player or spawner object?

[candid ginkgo]

on the player prefab

[real ingot]

Ah I didn't then I'll do that rn

[candid ginkgo]

https://docs-multiplayer.unity3d.com/netcode/current/basics/networkobject/

it talks about it at the very bottom

[real ingot]

After pressing client:

following after pressing start game:

[candid ginkgo]

yeah I'm running out of ideas now lol

[real ingot]

pretty much the same but I don't remember the last error

[real ingot]

I'm running out of brain cells

[candid ginkgo]

Just to be sure there are no other network objects rn right ?

like there's only the player spawner and the player prefab ?

[real ingot]

yeah. I'ma double check

yeah

unfortunately :P

[candid ginkgo]

And I'm pretty sure you already tried a few days ago but adding the player spawner to the prefab list doesn't do much I assume ?

[real ingot]

I did that just not long when I asked should I or should I not

no effect. Same thing

[candid ginkgo]

welp

unity forums it is

[real ingot]

Used it a little ago

https://forum.unity.com/threads/client-cant-join-the-server-prefab-not-found-changing-scenes-problem.1461890/

didn't expect this to take this long

[candid ginkgo]

From what I read what they recommend to do is to use the networkmanager's scene loader to load the scene but disable all it's game objects on the client's side

but then I have no idea how to prevent the networkManager from automatically synchronizing the scene when a client gets created

oh but actually that could work if it loads it all additively

[candid ginkgo]

basically replace the scenemanager.loadscene part by ```csharp
if(isServer) // called by server/host to load the scene for everyone connected
NetworkManager.Singleton.SceneManager.LoadScene("InGame", LoadSceneMode.Additive);
if(isClient) // called by client/host to make the scene visible
FunctionThatEnablesAllTheGameObjectsOrSomething():

[shrewd junco]

from what im trying, i still dont get the first error you are having. Check on the client after the error happens if the prefab list truly has the prefab 🤔

because this doesnt seem to be an error related to changing scenes, it happens as soon as u press join as client

[real ingot]

when I press client it doesn't change scenes so yeah

[candid ginkgo]

You'd also need to re-enable scene management in the networkManager

[shrewd junco]

but does it work even if you arent trying to change scenes in the first place?

[candid ginkgo]

^

[shrewd junco]

well you shouldnt exactly keep trying to press start game after the first errors :p

[real ingot]

true

idk I do that cause I feel like it

maybe magic will happen

Who knows

[real ingot]

what do you mean in this line exactly? FunctionThatEnablesAllTheGameObjectsOrSomething():

[candid ginkgo]

basically when you load a scene additively it loads the other scene while keeping the menu scene

sorta like dontdestroyonload I guess

so theoretically

If you load both the menu and the game

but only show the game when you press start game it might work

assuming the error came from the fact that ngo didn't like that you weren't using the networkManager's sceneloader

because once the client connects it'll automatically synchronize the scenes

problem being that you wanted the client to choose when joined the game

so technically the game will exist as soon as the client connects but he just won't see it. And then pressing the start game button will hide the menu and show the game

I saw people online say that to make it easier you can just make all gameobjects be the children of a root object and then you just enable/disable the root

[real ingot]

ok so the players load in the main menu scene. Ofcourse only the host spawned in. No errors when I press client nor when I press start game

the only problem is that it still doesn't spawn in the second player

the client player

you can see the game scene and the host player tho

just like bawsi said, something is wrong with the timing and this isn't getting called

or something like that

[candid ginkgo]

yeah that's really odd

you did switch the subscription of the method that spawns the player to the networkmanager's onsceneload right ?

wait nvm it doesn't even matter now that both scenes are loaded you can just call it from the startgame button

[real ingot]

the spawned script is the same as it was the last time I shared the code. I didn't change anything

[candid ginkgo]

ohhh

[real ingot]

the start network is the only one I changed

[candid ginkgo]

maybe as a temporary thing you can call the serverrpc that spawns the player in the startgamescene

after the mainmenu.setactive(false) add the call to the serverrpc so that it spawns the player

oorrrrr

double check that the OnSceneLoaded method is subscribed to the networkManager's onsceneloaded event

basically replace the thing in the onenabled/disabled by UnityEngine.SceneManagement.SceneManager.sceneLoaded +=/-= Onsceneloaded

[candid ginkgo]

if you didn't already do that

[real ingot]

idk if I can say "it worked"

[candid ginkgo]

eh at least it's different from last time lol

[real ingot]

the second player works tho

that's a really good thing

[candid ginkgo]

now need to figure out why there are three lol

[real ingot]

it's just that the host has 2 players now

[candid ginkgo]

can you send both scripts as code blocks ?

[real ingot]

https://paste.ofcode.org/c7yYSK49MEEHw5kHWWdeas

https://paste.ofcode.org/r7YUDRdGvj4VN4XL3wxhjT

[candid ginkgo]

if you disable the playerSpawner component do you still get 3 players ?

[real ingot]

btw where I did mainmenu.setactive(false); the mainmenu is a parent of StartNetwork gameobject

[real ingot]

I get 2

how?

[candid ginkgo]

I knew it

nice

I think the host called the rpc at some point because it loaded the scene

[candid ginkgo]

locally

[real ingot]

the player prefab is not assigned tho. How are the players spawning?

[candid ginkgo]

wait what ?

wdym it's not assigned ?

[candid ginkgo]

it is assigned isn't it ?

[candid ginkgo]

yeah

[real ingot]

Player Prefab

not the network prefab

the network prefab is assigned

I thought player prefab spawns automaticaly when the client starts

[candid ginkgo]

basically the player prefab is unassigned in the networkmanager because it spawns the player automatically as soon as he connects to the server

which in your case is bad since you want the client to join manually

so what the player spawner script does is spawn it when the serverrpc is called

[real ingot]

I'm guessing there's no way to spawn the player and put it in the InGame scene?

[candid ginkgo]

[ServerRpc(RequireOwnership = false)]
    public void PlayerJoinedSceneServerRPC(ServerRpcParams serverRpcParams = default)
    {
        // this is called on the server
        ulong id = serverRpcParams.Receive.SenderClientId;

        GameObject player = Instantiate(playerPrefab);
        player.GetComponent<NetworkObject>().SpawnAsPlayerObject(id, true);
        // since the prefab is a NetworkObject, it will be spawned on the clients automatically (hopefully)
    }```

which scene does it get spawned in ?

[real ingot]

mainmenu

[real ingot]

wait

no no no

how is PlayerJoinedSceneServerRPC calling tho?

when the component is disabled

[candid ginkgo]

you can still call methods when a component is disabled

[real ingot]

bruh

[candid ginkgo]

lol

[real ingot]

I fr didn't know that

[candid ginkgo]

no worries learned about it a few days ago as well

but basically it only gets called by the button now

[real ingot]

So I'm assuming I just have to leave PlayerJoinedSceneServerRPC in there and that's it

[candid ginkgo]

and when a player leaves you only have to despawn the object

[real ingot]

cause then nothing else but that is getting called

[candid ginkgo]

you can even move it to the other script and delete this one

doesn't really matter where it is

or

if you want to test something which might be a little cleaner

you can try removing the call to the rpc from the button

and replacing the subscription in the onenabled/ondisabled

not sure if that will work

but If it works

that means the spawning of the player isn't tied to the UI which I personnally think is cleaner

basically

remove the line that spawns the player in the startgame method

and replace the onenable/ondisable in the spawner script by this ```csharp
private void OnEnable()
{
NetworkManager.Singleton.SceneManager.OnLoadEventCompleted += OnSceneLoaded;
}

private void OnDisable()
{
    NetworkManager.Singleton.SceneManager.OnLoadEventCompleted -= OnSceneLoaded;
}```

ah but then that would mean the spawning of the player might happen even when the scene is disabled

yeah no scratch that bad idea

[real ingot]

I don't really understand why is it saying this when everything is fine

is it cause it's not public?

[candid ginkgo]

cuz you put it in the ienumerator

[real ingot]

oh

shi

[candid ginkgo]

lol

[real ingot]

that looked like I placed it in the class

it's 3 am can't blame my self

[candid ginkgo]

fair enough

[real ingot]

now onto the using only start game button

[candid ginkgo]

I mean it works like that don't need to change it tbh

the main problem now is making the players spawn in the right scene I guess

[real ingot]

true

just want to make it a 1 click not 2 for the players

I'll figure it out tomorrow

onto the main problem

[candid ginkgo]

apparently the way it works is that you need to set a scene as active

now I have no idea if the currently active scene is synchronized between all players but if it's not then you just have to call whatever method changes it

[real ingot]

https://forum.unity.com/threads/instantiating-objects-into-a-specific-scene.459108/

[candid ginkgo]

https://docs-multiplayer.unity3d.com/netcode/current/basics/scenemanagement/using-networkscenemanager/#active-scene-synchronization

[real ingot]

https://docs.unity3d.com/ScriptReference/SceneManagement.SceneManager.SetActiveScene.html

[candid ginkgo]

if they aren't synced you just have to call NetworkManager.Singleton.SceneManager.SetActiveScene() before you spawn the player

or whatever method they might have made for it to work with netcode

or maybe not even the NetworkManager.Singleton.SceneManager and just the normal one

idk that's just a bunch of checks you're gonna have to do I guess

[real ingot]

nah NetworkManager.Singleton.SceneManager doesn't exist, the SceneManager.SetActiveScene() works fine I believe but I'm having issues with the courantine so I'll do this tmr.

Too tired

atleast the main main part got fixed.

took us long enough lopl

thanks a lot tho @candid ginkgo and @shrewd junco

saved me months

hope I can learn more from y'all

[candid ginkgo]

pleasure's all mine, I learned a lot too just by trying to help so glad it worked out in the end 👍

[shrewd junco]

i dont really know all too much about multiplayer myself 😅

[rapid carbon]

[SerializeField]private float speed;
    private Vector2 direction;
    private Rigidbody2D rb;

    void Awake()
    {
        rb = GetComponent<Rigidbody2D>();
    }
    void OnMove(InputValue value)
    {
        direction = value.Get<Vector2>();
    }
    void FixedUpdate()
    {
        if(IsOwner)
        {
            rb.velocity = direction * speed;
        }
    }

this is my movement script and for somereason my player is still not moving

it has a network obj, client transform,network rigidbody2d but still isnt moving

why?

[shrewd junco]

Is it working for the host, or for no one?

[rapid carbon]

no one

[shrewd junco]

Probably IsOwner isnt true for anyone then, how are you spawning this player?

[rapid carbon]

just added player prefab in the network manager

[rapid carbon]

and its in network objs list as well

this is on the player

this is the manager

[shrewd junco]

That network object seems... wrong

[rapid carbon]

?

[shrewd junco]

I feel like it's missing some fields that would tell you if isOwner and other details

[rapid carbon]

idk

[shrewd junco]

I would suggest following the codemonkey tutorial for spawning players. Otherwise if spawning the player isnt the issue, then you should debug what the OwnerClientID is on this script, and possibly just throw "IsOwner" in that debug to make it clear who the owner is

[rapid carbon]

i m following his tutorial only

he spawned like this as well

[shrewd junco]

Were u able to recreate the same movement that he did? I was going to suggest that the network rigidbody was causing the problem because maybe only the host owned it, but you said no one can move which means that's not the case

[rapid carbon]

he used transform i m using rb.velocity

[rapid carbon]

it worked for a while

but idk what happened

let me try removing rb

[real ingot]

Try changing from normal to debug in the inspector

[shrewd junco]

You can also look at the rigidbody on each person and see if it's set to kinematic or not

[real ingot]

And look at the network object

[shrewd junco]

Its odd because even the normal mode should display more..

[rapid carbon]

nope doesnt work

[rapid carbon]

okk let me

[real ingot]

Everything seems fine unless he didn't take a picture of the whole network object

[real ingot]

Make sure your NGO is up to date maybe

[rapid carbon]

it is

[real ingot]

Do what the first warning said

Create your organisation

[rapid carbon]

idts not right now

[real ingot]

It's not gonna do anything except get rid of your warning. All you have to do is create it in unity and that's it.

[rapid carbon]

but thats not the problem right now

[real ingot]

Did you really take a picture of the whole networkObject in the player?

[rapid carbon]

let me

[real ingot]

Expand the NetworkObject component

[real ingot]

Wow

It isn't right

[rapid carbon]

?

[real ingot]

Make the inspector debug and take a picture of the NetworkObject expanded again

Top right 3 dots and debug from normal

[shrewd junco]

I knew I wasnt tripping, something is definitely off im just not sure what causes that

[real ingot]

Yep it's wrong

IsClient isOwner isHost isserver is Localclient is missing

[rapid carbon]

[shrewd junco]

Oh wait a second, this is the prefab itself

[rapid carbon]

yes

[shrewd junco]

Run the game and take show the network object when the host is in

Some of those boxes should be checked

[rapid carbon]

okk let me

[real ingot]

Nah it always should be there

[real ingot]

That's odd. At first I thought it might be the version of NGO but he said it isn't

[rapid carbon]

[shrewd junco]

I would still either just add debugs in that script like IsOwner and check if the rigidbody is set to kinematic, or redo the tutorial incase you accidentally changed a crucial part

[real ingot]

Right now the movement script can't even check if IsOwner cause the IsOwner in the NetworkObject doesn't even exist

[shrewd junco]

Regardless of what's displayed on the inspector, itll still have the IsOwner field

[rapid carbon]

😵‍💫

[real ingot]

Try creating a new object and adding the networkObject in there and tell us if the isOwner is in there or not

[rapid carbon]

where

[shrewd junco]

I would still just suggest to do these alone. As this would give you information as to why you cannot move

[real ingot]

Doesn't matter, in the hierarchy

[rapid carbon]

so i should add debug in is owner condition

[shrewd junco]

It will display a lot but yes you can do it there if you want

[rapid carbon]

okk let me

[shrewd junco]

Also can you additionally make sure you didnt accidentally set the speed to 0

[rapid carbon]

yes

its

debuging

its working

[rapid carbon]

nope its 8

[shrewd junco]

So IsOwner is printing true?

[rapid carbon]

yes

[shrewd junco]

Hmm just check the rigidbody then and see if its kinematic

[rapid carbon]

nope its dynamic

[shrewd junco]

I havent used network rigidbody 2d, I assume it applies the same logic as 3D

You may have some other error then, because I dont see anything here that would cause this

Just to be certain, try to debug what you're setting the velocity to be

[candid ginkgo]

just gonna throw this out there if that might help but I'm pretty sure that for the new input system to work when using a client side transform you might need to have it disabled by default and enable it locally when a client connects

I had encountered a problem like that a few days ago and that was what fixed it for me

https://docs-multiplayer.unity3d.com/netcode/current/learn/bitesize/bitesize-clientdriven/

[rapid carbon]

i have added a canvas to the prefab itself

[candid ginkgo]

pretty sure I read about it somwhere here

[rapid carbon]

and if the canvas !isowner then destory canvas

[candid ginkgo]

but I'm not sure if that was caused by the input system or by the character controller the sample used

[shrewd junco]

Ah that makes sense, I was going to ask them to debug the input next after checking what the velocity is being set to 😅

[candid ginkgo]

worth a try I guess

[rapid carbon]

i am doing that only

i have that canvas in player prefab and if player prefab is not owner the locally destroy the canvas

[shrewd junco]

Debug if the input is correct, if it's not reading input properly then it's not gonna move. What Tarook said above is how u would fix it if this is the issue

[rapid carbon]

oo

let me just debug the direction

also should i add a is owner condtion here?

[candid ginkgo]

you can but I think you should just have the component be disabled by default and activate it on a player's prefab when he connects

so that there only is 1 that is enabled locally for each player

[shrewd junco]

Though it should still work if they only connect on a host and try moving

[candid ginkgo]

yeah I don't think it'll break anything but I think if another player connects and it has an enabled player input component it'll make a bunch of errors in the console

[rapid carbon]

so...

apparently

its just not taking the input

no debug there

[shrewd junco]

When u are testing this, are you testing only on a host or do you have a host and client connected?

[rapid carbon]

host

[shrewd junco]

Because this really should work if its only 1 player, where 2 might be causing issues

I dont know anything about new input system honestly

[rapid carbon]

btw this is netcode 1.1.0

[candid ginkgo]

then try doing something like this ```csharp
public class OwnerComponentManager : NetworkBehaviour
{

private PlayerInput playerInput;

private void Awake()
{
    playerInput = GetComponent<PlayerInput>();
}

public override void OnNetworkSpawn() // most components are disabled by default
{
    base.OnNetworkSpawn();

    enabled = IsClient;

    if (IsServer)
    {
        // not much to do here since your project has client side priority
    }

    if (!IsOwner)
    {
        enabled = false;
        return;
    }

    // player input is only enabled on owning players

    playerInput.enabled = true;
    // enable other scripts that you want the client to use like the player movement and such
}

}

[shrewd junco]

You should definitely upgrade

[rapid carbon]

y does the package manager have 1.1.0 only

[shrewd junco]

You can upgrade by changing the version number in some json folder I forgot the name of. Theres some result on google that tells u how to I believe

[rapid carbon]

Isn't there just

A git url?

[candid ginkgo]

are you on unity 2022 ?

[rapid carbon]

2021

[candid ginkgo]

ah then not sure how to help sorry

[rapid carbon]

Can I port my project to 2022?

[candid ginkgo]

of course

[rapid carbon]

How

[candid ginkgo]

but then you can't go back to 2021

[rapid carbon]

Would that cost me anything?

And is 22 lts?

[candid ginkgo]

not as far as I know but if there's a way to upgrade netcode without having to change the unity version I would try that first

[candid ginkgo]

yes

[rapid carbon]

Well then i think u should go with 22 anyways something new won't hurt ig

[shrewd junco]

You dont need to change unity versions, unless you want to for other reasons

Just changing the version number in like packages.json should be fine

[rapid carbon]

2022 3 5f1 is fine?

[candid ginkgo]

try that first it'll be simpler
