That's great, but I couldn't even get photon to update two ways (the host was frozen on the non hosts screen).

[wary gorge]

whats great?

i solved it btw

[wary gorge]

thats weird did u make sure to hide the camera and controller when the view wasnt yours?

[oak portal]

I have created an XR project via MRTK that incorporates ML-Agents. I would like training of the agents to be done live when the project is built to the HoloLens. I need to build the project to the HoloLens and run the machine learning training via an external computer--how can I facilitate communication between the two to run ML training in real-time?

Do I need to run ML-Agents training on a headless server and build the project in server mode? Or do I have to look into C# socket scripting? I'm new to networking so any guidance is greatly appreciated. Thank you.

Pun question:

    {
        int viewId = gameObject.GetComponent<PhotonView>().ViewID;
        float currentHp = _player.CurrentHP;
        photonView.RPC("SendUIClaimNetworkHPBarMessage", RpcTarget.OthersBuffered, viewId, currentHp);

    }

    [PunRPC]
    protected void SendUIClaimNetworkHPBarMessage(int viewId, float hp)
    {       
        if (photonView.IsMine)
        {
            Debug.Log("Whats the view id: >>>>" + viewId);
            _controller.SendUIClaimNetworkHpBarMessage(viewId, hp);
        }
    }```
 

My understanding is that I should get a call from everyone else and get THEIR viewId, but for some reason the only viewId I get is my own.

[cedar belfry]

I'm looking to setup a game just for fun and am wondering if using SteamWorks would be a good idea, and how do I connect this to Unity? I'm currently using Mirror.

[cedar belfry]

Don't know if I should use Steamworks.net or FacePunch

[zenith rampart]

Yeah it all worked fine its just like I said the hosts character was frozen on the non hosts screen.

[wary gorge]

hmm

r u using pun2 or something newer

?

[fringe pasture]

when someone gets the chance I keep getting thies 2 errors

Error    CS0115    'ConnectToServer.OnConnectedToMaster()': no suitable method found to override
Error    CS0115    'ConnectToServer.OnJoinedLobby()': no suitable method found to override

eventhough in the vidio i watched it works fine and i followed the steps up until this point where i stopped
btw its in stem 4 of https://www.youtube.com/watch?v=93SkbMpWCGo

[naive rapids]

I started working with Unity's mirror plugin and the networking features today and I am having trouble figuring out how to destroy objects server side

i know its probably a fairly simple process but i can find very little information on how to do it succesfully

[zenith rampart]

I think so

[zenith rampart]

Asset:
EXIT GAMES
PUN 2 - FREE

[zenith rampart]

And I have it linked to a pun server, using photon views and transform views to photon network instantiate prefabs from the resources folder, and I made sure to disable the other players camera but it still doesn't work both ways

Do you think getting Pun 1 would help?

[placid stream]

i follow this tutorial https://www.youtube.com/watch?v=kld9sINMLGw and i done everything it dont work idk why mu playerlistitem dont spawn

[teal timber]

Can someone help me with netcode for gameobjects how ownership of the player object works

I'm working on player movement when I build and run to test I launch host in editor and client on the build and the client doesn't have ownership of it's spawned player object.
The host has ownership of its playerobject and can move around probably just because it the server tho
I have tried to assign ownership via clientid but dint seem to work I don't know what am doing wrong lol

[wary gorge]

noo bro, its so outdated

but i would recommend photon fusion or quantum (i just dont know them)

but they are new so try em

[naive rapids]

is it not possible to send parameters to a serverside void?

im trying this simple script but keep getting the object reference not set to an instance of an object error

it lets me convert the gameobject's name to a string and print that but not just get the name from teh gameobject itself

i finally got it to work 🥲

[compact imp]

trying to use the new netcode library, does NetworkList<T> actually work? it doesn't seem to trigger change event on client

https://pastebin.com/0T3sHuA4

Could anyone help with my Multiplayer issue trying to get movement to work my code has the host move and sync transform but the client on the built game cant move dont know what im doing wrong

[quaint moon]

It is your just looking at the logs of the client

It’s in the logs of the server since it’s a command

[winter patrol]

im having touble following this video and the comments arnt much help https://youtu.be/y69wBS13wwA?t=1085
here is the code i have with the error as a comment on the line that the error apears at https://hst.sh/eqifugegap.cs

[naive rapids]

I am trying to code an item in unity mirror, so that when it is picked up, its transform is changed to match the player's

this works fine for the host client

but no matter what I do, the other client's item will not change transform on the server

I have tried everythign for two days now, I think I narrowed teh issue down the being that on the host client, the item is marked as isServer, which it is not on the other client, how do I change this?

I guess teh better question is, server authority sucks, this is a game Im sharing amongst friends so i could care less about handling cheating, how do I switch a game to client authority?

[dense ravine]

(photon pun) if anyone wants to help me please hit me up in the dms, its a lot of typing work to exactly explain what i want. if someone has some spare time and can help me, please. its about destroying objects, switching cameras, and raycast. (more complicated than this but ok)

and i just cant get it to work damnit

[shut knoll]

will the netcode documentation on the unity website still work for 2D?

[dense ravine]

yes, most of it

[shut knoll]

okay thank you

i find it extremely confusing so thats fun

[dense ravine]

haha

[shut knoll]

i think im gonna follow this

video

because my brain doesnt process most info unless its being told to me

[quaint moon]

Don’t build and run like that

Use parrelsync

[rocky nebula]

@naive rapids have you tried checking the mirror discord, I believe this question has occurred a few times

[silk linden]

Which one of these services is better for multiplayer?
Netcode, Fishnet, Photon Fusion, Mirro, etc.

[haughty heart]

Neither, they're all made for multiplayer and do so successfully.

Your job is to research the pros and cons of each and make an informed decision.

[naive rapids]

don’t worry i fixed it

thanks though, i didn’t know there was a mirror discord

[quaint moon]

Google it

[subtle fog]

Hi everyone,
I would like to ask you what networking solution do you suggest to a game which has

• players as hosts (no dedicated server)
• rts-like gameplay (2-4 players per room)
• game rooms to join
  (In terms of architecture, its almost like Warcraft 3)

What I found is Mirror or Photon Quantum would be the best options, but i dont have a lot of infos on Quantum. On the other hand, Mirror would require additional solutions for lobbies/rooms, and I am not sure about the performance

[half sage]

whats a good free multiplayer network for an fps shooter?

[haughty heart]

Nothing is free. Free to try, sure. Photon and Mirror are popular options.

[regal dune]

I’m looking into networking at the moment, take a look at the EPIC solutions. They provide a suite of free tools (lobby, relay etc) https://dev.epicgames.com/en-US/services

[subtle fog]

isnt it only for UE?

[regal dune]

No

Works with a whole bunch of stuff

[weak plinth]

i just want to make it when
u create a room
if its not a private one
it appears on the servers list

using photon

[runic rampart]

I'm using Netcode for gameobjects - we got Exception: Server Scene Handle (-422) already exist! Happened during scene load of EmptyWorld with Client Handle (-450). Any idea what this could be? We were using a built version of the game

[dim smelt]

Made a few tutorial videos for Fish Networking and Visual Scripting. The exact same concepts apply to C# scripts so it should be easy to get started either way. I will be making a few dozen videos so check the playlist if interested. Thanks!

[velvet sonnet]

does anyone know how to change Unity Transport IP Address and Port during runtime? I'm using Netcode for Gameobjects
https://i.imgur.com/6Z43TRA.png

[velvet sonnet]

nvm got it, needed namespace "using Unity.Netcode.Transports.UTP" , then NetworkManager.GetComponent<UnityTransport>().ConnectionData.Address="someString";

[summer geode]

Hello !
I have a question
i'm using Unity Netcode for Gameobject and i'm trying to disconnect my client.
Basically; it's giving me this error :

NullReferenceException: Before using the library you should call Init() and do not forget to call Shutdown() afterwards

I searched on google, and it's telling me to use this :

Networktransport.Init();

Now the problem, is, as you can see in the screen : I do not have this function.

I'm heritating from NetworkBehaviour in my script, not Monobehaviour.

Would someone know how to fix that please ?

Someone told me I had to get an instance of Network Transport but can't figure out how
I'm sorry, I'm pretty new at networking. Thank you ! :)

[austere yacht]

It’s referenced by the network manager but to disconnect your client you don’t need to access the transport. You’d just call shutdown/disconnect on the NetworkManager, the same for connecting and startup. It should init the transport for you. Usually you need to only deal with the transport for setting up things specific to its implementation, remote address and port.

[summer geode]

It's what I'm doing basically
I'm starting the client at the start
And disconnect it when I want to later
But it's giving me this error

[austere yacht]

can you post relevant code for it?

[austere yacht]

Alterntatively you can try to not call StartClient() immediately when starting the game but instead wait a second to give the library time to initialize

[summer geode]

Sorry I was eating

Here it is :)

It's long so I couldn't send it in a discord message i'm sorry

[austere yacht]

use a paste site

[raven halo]

Does anyone know the optimal way to use Netcode for LAN multiplayer?

I've only used Photon in the past and it was server-based, so I am a little disoriented with the new documentation and how to use it. I think I need to use the Unity Relay services, but I'm not sure if that's the right direction.

[austere yacht]

You don’t need relay for LAN

[raven halo]

Oh, I see. For reference, I was following this tutorial https://docs-multiplayer.unity3d.com/netcode/current/learn/dilmer/dilmer-video/index.html and me and my friend couldn't connect to each other without the Relay for some reason, that's why I got confused.

[shut knoll]

how would i go along making a code based lobby system ?

[somber drum]

How do you guys manage your ccu tests? Is there any reliable way of doing it autonomously(without humans)?

[pulsar lion]

most times people just do a public stress test

[somber drum]

Fair.. thanks 🙂

[maiden bear]

1. create headless client just for that and run thousands of them.
2. capture what tpc connection your game sends, create script on java, phyton or anywhere else which dupolicates the same TPC packages and sent alot of them. depends on game, transport and etc.

[somber drum]

200 player cap fast paced udp-based shooter, nothing extraordinary in numbers I'll do more research with the above info provided appreciate it^^

[maiden bear]

for 200 headless clients will be enough. and it is a bit easier to make. you will need to create fake controllers but thats about it.

[somber drum]

yeah, it's really just testing the aoi across the map and seeing how it all goes down in concentrated numbers.. way more freedom than organizing public tests. Sounds easier than I thought

[crisp panther]

anyone experience with photon dedicated server?

I did research it was something with fusion

[stiff ridge]

What is the actual question?

[zinc marten]

does anybody here work with netcode for gameobjects?

Im trying to access the connected clients so i can sync the data for all clients but I get an error saying that connected clients can only be used on the server. Anybody know how to fix this? Using IsServer does not allow the clients to send the data which is what I want.

[austere yacht]

Sounds like a misunderstanding how sync works in netcode

You need to send the data to the server and have it then send the data to all interested clients. This is done via Server/ClientRPCs or custom messages with custom handlers.

[zinc marten]

Yeah.. I'm kinda confused about how that even works. For example now I want to have a scoring system which is two players that move around and touch a ball and if the ball becomes the color of the player he starts gaining points. However I cant figure it out. I have two network variables player1color and player2color and they are compared to the ball color to see who is controlling it right now. I think my logic is completely wrong right?

[austere yacht]

its hard to say, one thing i'd do is abstract this notion of "a player controlling the object" and not use the netcode directly do do that.

but to explain how exactly is tedious and wont help you, i'd recommend reading the netcode docs in their entirety (they aren't that long) until you fundamentally understand how stuff is supposed to be done, and from there it is somewhat obvious how these kinds of systems are implemented

[zinc marten]

okay thank you for your input!

[half shuttle]

does anyone know how to destroy an object on collision using photon as the client

[stiff ridge]

You can call PhotonNetwork.Destroy(go) on one of the clients. In best case, the client which currently controls the object, will do the Destroy.

[weak plinth]

how can I make this work on other players over the network. right now it only works on monsters or other players on a local build.
caster.combat.DealDamageAt(candidate,
caster.combat.damage + damage.Get(skillLevel),
stunChance.Get(skillLevel),
stunTime.Get(skillLevel));

[night thunder]

Heya, quick question, how is shooting usually handled in online shooters? They wouldn't be client side cuz cheating and stuff but most shooter seem too accurate to me to not be clientsided, is there some trick to that?

[austere yacht]

yes, there are a bunch of "tricks" to it, you can get the primer on all of those here: https://www.gabrielgambetta.com/client-side-prediction-server-reconciliation.html

[austere yacht]

you can also have a look at Photon Fusion and Quantum for specific, opinionated ways to implement them

you can put 0.0.0.0 in there to accept all incoming requests, localhost only responds to 127.0.0.1

[crisp panther]

nvm I think I just use mirror instead

[weak plinth]

anyone got any advice?

[spring crane]

Use debugger to step through it.

[crisp panther]

and debug. log in your line to check your current action

[crisp panther]

you you mean like only able to trigger on enemy well player hit enemy? if that it mind be something with naming for example tag = enemy will only run this script

cause seem was network gameobject won't work cause even object will be spawn from server object id you need to let the project to know where your object id was at

https://forum.unity.com/threads/cant-find-a-way-of-getting-player-ids.402519/

[weak plinth]

this only happens on login with a remote server, not server and play

does anybody know hot to check ms ping on all clients through netcode for gameobjects?

@zinc marten Not familiar with netcode particularly

But I believe you should be able to have a "round trip time"

That you can access like you access a network time

movement only shows on 1 of my clients for some reason, i already have the Networking Transform on the player prafab and the spawning and everything works, except the fact that u can only see movement on one of the clients

thoughts?

[half shuttle]

can someone please help me

[jaunty crane]

@thick valley are you sending the inputs to the server, or are you moving directly on the client?

[thick valley]

Oh I completely moved to photon it’s 1000x easier lol

Mirror is so much more confusing

[empty night]

Can someone help me fix this? this script gets the server time from playfab (in utc) the coverts to my local time zone (est) , then displays that in the scene.. Everything works fine on pc in the editor but when i build for internal tesing on google play and download to my phone it does not work
my script

[crisp panther]

Question if i wanna put my game build out from webGL to my own website how ya? using mirror

[stiff ridge]

That's a little vague, sorry.
No movement at all? Does that mean you can't even control your local character? If so, check your input control scripts. They should be accepting input for one character.
This is covered in some detail in the PUN Basics Tutorial, so maybe it helps reading that once more?!

[sharp pawn]

Hey, I have a problem with NetworkVariable. I am using a NetworkVariable<FixedString32Bytes> and it looks like the game throws this error:
Exception: Type Unity.Collections.FixedString32Bytes is not serializable - it must implement either INetworkSerializable or ISerializeByMemcpy
This error appears on the host side when a client connects, but host itself has no error like that happening. I am using FixedString32Bytes for player nickname, so if there is a better way to handle this, please enlighten me.
EDIT: Fixed, turns out I was just using a wrong version of Netcode. A rookie mistake.

[fringe pasture]

when someone can help, can someone tell me how to make my player invisible to me in first person but still visible to others

ive tried puting my player in a layer not seen by the first person camera but i cant see others and they cant see me when were in firsty person

[jaunty crane]

if(IsClient && IsOwner)
{
  GetComponent<MeshRenderer>().enabled = false;
}

@fringe pasture this should work if you put it in the start method or something

[fringe pasture]

ok ill try it

i couldent get to work the way i wanted but i found a new way, thanks anyways

[jaunty crane]

np

[fringe pasture]

when someone gets a chance when ever i click the menu button i have it gits rid of the player but it dosent load the menu and leaves me on the lobby scene this is in my player controller

i fixed it

i maoved the overide void too the manager

[crisp quest]

is there a way to call a clientRpc only on the localplayer in netcode for gameobjects? I know I can probably run a (isOwner) check inside the rpc function but im trying to avoid that

[austere yacht]

It’s described in the docs https://docs-multiplayer.unity3d.com/netcode/current/advanced-topics/message-system/clientrpc

[crisp quest]

thankyou, I did find it after a bit. I have one more question, I can't seem to get my networklist values from client side, is this intended? I try to run .count on client even as a clientrpc and consistently 0. when running .count on server side it returns the actual count though.

[spring crane]

Yea it's common for servers to not broadcast that information.

[crisp quest]

can you help me out with this case, I have a solution but just trying to make sure it's the best.

Lets say I have a networklist<Vector3> called occupiedPositions.

whenever a new player joins the game, I make a local copy of those positions to a List<Vector3> localOccupiedPositions.

the way I do this is by running a

CloneOccupiedPositionsToLocalServerRpc()
{
foreach(Vector3 pos in occupiedPositions)
{
AddToLocalListClientRpc(Vector3 pos);
}
}

AddToLocalListClientRpc(Vector3 pos)
{
localOccupiedPositions.Add(pos);
}

i tried passing a list of vector3s to my client rpc first but doesn't seem to like it, I get the following error:

Don't know how to serialize NetworkList1. RPC parameter types must either implement INetworkSerializeByMemcpy or INetworkSerializable. If this type is external and you are sure its memory layout makes it serializable by memcpy, you can replace Unity.Netcode.NetworkList1<UnityEngine.Vector3> with ForceNetworkSerializeByMemcpy1<Unity.Netcode.NetworkList1<UnityEngine.Vector3>>, or you can create extension methods for FastBufferReader.ReadValueSafe(this FastBufferReader, out Unity.Netcode.NetworkList1<UnityEngine.Vector3>) and FastBufferWriter.WriteValueSafe(this FastBufferWriter, in Unity.Netcode.NetworkList1<UnityEngine.Vector3>) to define serialization for this type

I tried passing both List<Vector3> and networkList<Vector3> basically get the same error for both, right now it works fine as long as i pass one by one

CloneOccupiedPositionsToLocalServerRpc()
{
  foreach(Vector3 pos in occupiedPositions)
  {
    AddToLocalListClientRpc(Vector3 pos);
  }
}

AddToLocalListClientRpc(Vector3 pos)
{
  localOccupiedPositions.Add(pos);
}

reformated my code

[jaunty crane]

I don't know if this would cause that error, but you do need [ServerRpc] and [ClientRpc] in front of the methods respectively

[crisp quest]

for sure, i left it out of the code, i got it working, im just wondering if theres a better way to clone a networklist to a local list

[jaunty crane]

public struct NetListVector3 : INetworkSerializable
{
    public List<Vector3> list;
    public void NetworkSerialize<T>(BufferSerializer<T> serializer) where T : IReaderWriter
    {
        for(int i = 0; i < list.Count; i++)
        {
            Vector3 value = list[i];
            serializer.SerializeValue(ref value);
        }
    }
}

this will probably be better

ive been trying to find a way to make push to talk with photon voice but i couldent find much, anyone know a good tutorial to get some sort of push to talk set up?

[violet jolt]

I am trying to send a file containing level data from Unity to my (currently local) flask server. Can anybody point me to the right direction? The main problem is interpreting the data that is arriving at my server.

levelData = request.data.decode("utf-8")
does not work.

file = request.file
tells me there is no file.

Ok I got it. This is the C#-part of the script that converts my data to a wwwform:
WWWForm form = new WWWForm(); form.AddField("name", in_levelData.name); form.AddField("data", in_levelData.text);

and this is how I interpret it on the other end (flask):
levelForm = request.form levelName = levelForm.get('name') levelData = levelForm.get('data')

Its always the same. You fiddle around for 60 minutes without progress, then ask on the discord only to solve it 5 minutes later. 😅

[night thunder]

Short question, is there something like a Client Network Transform within the Netcode for Gameobjects package? Im having trouble letting my clients control themselves, host can move fine, scripts are accordingly disabled/deleted, so I'm wondering if I got the wrong network transform on the prefabs

[bright mauve]

Use NetworkTransform https://docs-multiplayer.unity3d.com/netcode/current/components/networktransform
and when moving the player you can move it offline however you want but use if (is owner https://docs-multiplayer.unity3d.com/netcode/current/api/Unity.Netcode.NetworkBehaviour#isowner)
to check if you are the one moving the player.

[night thunder]

Thats exactly what I'm doing already and thats not my question at all xD I'm trying to figure out how to give a Client ownership of its network transform, shouldn't there be a "make Client have authority over this object" kind of setter?

[fringe pasture]

when someone gets a chance, i use photon voice 2 and i am trying to make a voice indicator for my push to talk, this is my script (playerController)

void Update()
    {
        if (view.IsMine)
        {
            // push to talk
            if (Input.GetKey(KeyCode.LeftShift))
            {
                recorder.TransmitEnabled = true;

                micOn.SetActive(true);
                micOff.SetActive(false);
            }else
            {
                recorder.TransmitEnabled = false;

                micOn.SetActive(false);
                micOff.SetActive(true);
            }
      }
  }

Hi can anyone help me with Photon Pun2?

Im using Photonview.IsMine to make sure all characters dont move at same time

It works for all except host

The host isnt able to move

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Photon.Pun;

public class PlayerMovement : MonoBehaviour
{
public PhotonView view;
public Rigidbody2D rb;
public float speed;

private void Update() {
    if(view.IsMine){
        float inputDirX = Input.GetAxisRaw("Horizontal"); 
        float inputDirY = Input.GetAxisRaw("Vertical"); 

        rb.velocity = new Vector2(speed * inputDirX, speed * inputDirY);
    }
}

}

could anyone help?

[fringe pasture]

when someone can help, I keep getting this long errors when i try to execute code in OnTriggerEnter. the errors: http://pastie.org/p/3fSltOAmeiB7kSK6CFB8wI the code: http://pastie.org/p/2udlLfMlqdCASdIReEwgnQ my only issue is that it does not destroy the flag.

[patent fog]

L:18 you try to access a gameobject of a param that is already a gameobject ? That might be a typo, but even then, I'm pretty sure you can't send a gameobject through RPC

That's what the error message is trying to tell you : it can't serialize a gameobject to send through the network

I don't use PUN but I'd assume you're have to send via RPC the network id instead, then find the matching gameobject on the server side

@fringe pasture might be other ways to achieve that with PUN but that's the first naïve approach I'm thinking about

[dapper lily]

(Using Mirror) I need to set up a system using either proximity or collision, so that I can call events when two objects get close to each other. Does anyone have any recommendations for how to do that? 😦

[patent fog]

You just described OnTriggerEnter and OnCollisionEnter callbacks

Are they what you are looking for?

[dapper lily]

Do those work with Mirror? 😮

[patent fog]

That's Unity engine

[dapper lily]

I'll give those a try and see what I can do, thank you 🙂

[patent fog]

Not sure if mirror have network-aware equivalent

You'd have to sync data yourself if need be

[fringe pasture]

well how could i have a gameobject that gets destroyed when any player touches it

[patent fog]

Like I said, I would pass the network ID instead of the GO in that RPC, and see if PUN provides a method to find GOs by id. Then you're back at the same point

[fringe pasture]

ok

but how would i find the network id of the object

[patent fog]

There's also seem to be PhotonNetwork.Destroy() variant for networked objects

[fringe pasture]

ok

[sharp pawn]

Is using NetworkVariables a good idea of handling player inputs, or should I perhaps use RPCs? I was thinking about making it so the client can set the NetworkVariables (basically floats, for horizontal and vertical input), and then the server can read those and use them in the controller script (apply throttle, brake or turn). This way I can replace ClientNetworkTransform with NetworkTransform and have nice, realistic collisions

Looking at my case, I think it makes sense, but maybe someone more experienced can enlighten me

[austere yacht]

network variables are just wrappers around messages to make the more convenient, same as RPCs, the difference is just that network variables retain the state of the last message received and enable delta compression (only sending a network message when the value has changed). Based on that property (retained state vs ephemeral state) you decide which one suits your use case better. another point of view is that RPCs model events, variables model state. Naturally you can manually convert one into the other at any time. Whether you sync inputs with either one depends on how you receive inputs. On the server you will likely want to retain some sort of input state between ticks. @sharp pawn

[sharp pawn]

Hm... I guess this confirms my idea. I read the input using ReadValue<float> when an input is performed. I think NetworkVariable will be better, since otherwise I'd have to send RPC like every frame (or, just send them on change, but then I think this is what NetworkVariable actually does)

I can try, we'll see how it works out.

[fringe pasture]

when someone gets a chance how could i destroy all objects with a tag and have all players see it (i use photon for multiplayer)

[sharp pawn]

It looks like NetworkVariable based player movement serverside works, but there are some problems. Aside from small issues like being unable to read speed from rigidbody (because it's kinematic), or the obvious (but small) input lag, there's a thing that on the client side, the vehicle seems to be moving in a very shaky way, as if the interpolation was having some problems. On the server side, as expected, the movement is smooth. Any idea on how to fix that?
Ok, apparently for this kind of issues there is client-side interpolation, like written here: https://docs-multiplayer.unity3d.com/netcode/current/learn/clientside_interpolation/index.html

[hollow linden]

How do i fix this??? (Using mirror) Ping me with answer

[rain arrow]

Hey all, general question if I may (I'm new to this stuff). I set up a client and server using riptide networking and a video guide on YouTube. The issue I'm having is that, while i can connect the client from my own network, I cannot connect from outside my network. The issue seems to be more with my computers personal ip address because even with port forwarding and adding exceptions to inbound and outbound ports I cannot connect. The issue seems weirder since I csnt even ping my own public ip in the cmd.

I believe I've set the server and client side connections correctly and its an issue internally with the PC or network settings.

My question with all that said, should I be okay to continue working on my project with the local connection working or should I fix the issue with my public ip first?

[signal talon]

anyone here use lite net lib?

Is there any way to know when Netcode is about to reach the next tick?

any events I can subscribe to or something?

Hello,
I was working on some api calls and wanted to keep a separate cs file for all the network based commands.
Sould I use a normal cs class or go for something like a singleton or something else

[pulsar oak]

I want to make sync movement which means movement per tick.
Idk why but this doesn't guarantee me sync movement

Delay between clients 100-600 ms seems like server work for them individually

[civic dune]

hi, so i'm making a multiplayer fps using steamworks. i made it so that when a player gets hit, the function DecreaseHealth() in this script https://gdl.space/apicuropud.cpp gets called. the amount is the damage variable of the gun. for some weird reason though, the health doesn't decrease, but the function gets called. does someone know what could be wrong with this?

[olive vessel]

The amount should get decreased on this instance of the script

But I see no code to broadcast this to any other clients or the server

[civic dune]

wdym

how do i do this

[olive vessel]

There's a lot of Mirror tutorials online, some covering this topic

The Mirror does have a synchronisation section too I think

Is Netcode for Gameobjects "safe" to use in a commercial project? Thinking about a co-op type of game.

[rustic shard]

Hi all! Can someone point me in the right direction please? I'm trying to learn more about Netcode, almost all of the links are broken: https://docs-multiplayer.unity3d.com/netcode/current/about. I have tried looking for tutorials, the ones on YouTube are a year out of date and half the code they are using is deprecated. I'm considering using Mirror, but I would really rather use Unity's official networking solution.

[civic dune]

the network manager wants a player object controller, i assume thats a script? does the object you drag in have that script?

[olive vessel]

There were a lot of changes between versions 0.1.0 (MLAPI) and the newer release 1.0.0 (Netcode for GameObjects), so tutorials for MLAPI might not match up 100%

They have a Discord pinned in this channel if you're not already in it, might be worth letting them know about that docs page

[civic dune]

hey, does someone know what this error means?
FieldAccessException: Field 'UnityEngine.RaycastHit:m_Point' is inaccessible from method 'Mirror.GeneratedNetworkCode:_Write_UnityEngine.RaycastHit (Mirror.NetworkWriter,UnityEngine.RaycastHit)'

I am making a multiplayer game with my friend, and the game works when your on the same computer twice (ie one in the built project, and one in the unity editor). however, when i try to join a server created on my friends computer, it doesnt work

[olive vessel]

Has your friend done the necessary port forwarding

[inland pier]

what is that? all i know is that he is using photon

[olive vessel]

Well it’s different for Photon PUN, should have said that in the initial message

You’re joining the same room?

[inland pier]

yes same code, although when you click the join button nothing happens

we fixed it idk how tho

I'm not sure if this goes in networking, but I want to use the player in the screen to do some stuff, but I can only put the prefab in the inspector? how can I overcome this in code

[sharp pawn]

How are RPCs handled when there's many instances of one script (like, one per player object)? If I call a ClientRPC like firstScript.DoSomethingClientRPC() then will it fire only for that one given script? Or should I use ClientRpcSendParams to specify the client? Sounds obvious but I'm asking to make sure.

[austere yacht]

call the subscribed function from OnNetworkStart or whatever it is called in your library

[spring crane]

Generally the default is that the RPC is fired on every remote instance unless otherwise specified by a parameter like ClientRpcSendParams.

Oh and multiple instances are generally separated by some sort of ID that is automatically handled by the networking library.

[fringe pasture]

anyone know how i could teleport all players to a random piosition when the host hits start

[austere yacht]

The server/host can always move everyone. So you just need to set everyone‘s position in the server/host‘s NetworkStart() method (assuming you have Network transforms of some kind on all of them)

[fringe pasture]

ok

[fringe pasture]

this is in my player controller and it wont open the menu scene when i leave the room

public override void OnLeftRoom()
    {
        if (view.IsMine)
        {
            PhotonNetwork.LoadLevel("MenuM");
        }
    }

how would i fix this

[fringe pasture]

(photon PUN2) how i could teleport all players to a random position when the host hits start, ive fiddled with my code all sorts of ways to no avail

[calm granite]

I have a question, I made shooting, but it doesnt show up on the other client, the other client also cant shoot. I basicly shoot a raycast from the player and check if it has the PlayerTarget script i made

any help is appreciated

my code is:

This is my hotbar logic script: https://paste-bin.xyz/73949

this is my player movement script:

https://paste-bin.xyz/73937

and this is my player target script

https://paste-bin.xyz/73938

[still hare]

I doubt anyone is going to download your code just to see it, so you should put the hotbar logic in a paste site as well

[calm granite]

ok

there i did it

@still hare

[still hare]

Well, for one, you SetIsShooting to true at the top of the Shoot function, but then you set it to false at the bottom. This code runs instantaneously, so basically it's just as if you never set it to true in the first place...

Does the damage get dealt though? Only the visuals aren't working?

You want to use RPCs for stuff like this, not SyncVars

[still hare]

Remember, this only runs on the server since it has the [Command] attribute

So of course other players wouldn't see muzzleflashes

Only the host player can!

[calm granite]

no

[calm granite]

wait so I have to use rpca

rpcs

[calm granite]

@still hare it shows the muzzle flash now but it doesnt register shooting each other

[still hare]

Well, look at what you do when you call Shoot. You try and Raycast, but you are doing it from the server's Camera.main, not the players.

Remember, anything tagged with the [Command] attribute will only execute on the server, and it will use any references from the server's scene.

It knows nothing about the client's scenes.

So every time a player shoots right now, it's trying to shoot from the host's camera position and direction.

[calm granite]

mhm

so how do I make it know if it hit the other player

@still hare

[tranquil hull]

Is it possible to use ServerRpc/ClientRpc without inheriting from NetworkBehaviour? I'm using Netcode for Gameobjects

[olive vessel]

Doubt it, pretty sure that's the point of a NetworkBehaviour

[austere yacht]

no

[high night]

Have another class, you can call it something like "CommunicationObject"
Make it accessible from anywhere, like a singleton

And call the rpcs there instead

If you don't want to inherit from NetworkBehaviour, I assume you already have a plan to keep track of this particular gameobjects reference over the network

[velvet sonnet]

Yes, all my spawning is syncing is manually handled via RPC. I don't want to use scene management, so I disabled it but that means I can't have pre-existing NetworkObjects within my scene, meaning my GameManager that handles all RPCs cannot have a NetworkObject, meaning it can't send RPCs anymore....

I tried using the prefab/hash override but it doesn't work right. All it does it create a clone of my existing GameManager on game start, then disables all scripts on it.

[austere yacht]

You could just remove netcode and just build your own thing on top of ENet

[velvet sonnet]

eeee

ouch

that's way beyond me lol

[austere yacht]

Why are you trying so hard to remove all benefits and convenience of netcode?

[velvet sonnet]

I want to spawn Addressables in my Netcode project, but Netcode does not support Addressable spawning. So therefore all my spawning and syncing must be without NetworkObject components on them. Which is fine, I have the code for that, but my scenes are also Addressable, and Netcode SceneManagement doesn't work with Addressable scenes either. So I disable Scene Management, but turns out disabling SceneManagement throws errors if you have any pre-existing NetworkObjects in the scene. I have one pre-existing NetworkObject, and that is my GameManager, the sole GameObject that sends/receives RPCs. So if I remove NetworkObject from my GameManager, I can't use RPCs

Anyway, currently trying out Fishnet.

I'm trying to use unity's Relay solution on top of my Netcode for gameobjects. When I was using just Netcode everything was working fine. With Relay the host can join just fine but when the client joins with the relay code I get a lot of errors. Is there a way to find the specific gameobject with that hash? And also why would the host be able to join no problem but the client cant?

[regal karma]

Hi, sorry for the longread 🙂

I have an app, which is easiest to describe as an imitation of a webpage: you have a vertical ScrollRect with a bunch of interactive elements (Image Gallery, Text, Video, etc), all of which are generated from an input from an external CMS. All this is done with regular Unity UI objects.

Now I'm trying to implement a "Group Mode" for this app, that is: a "Teacher" uses his device to interact with the content, and then all "Students" are seeing a duplication of what the Teacher is doing on their devices; sort of as screen mirroring (across the LAN network).

I see the implementation of this Group Mode in 2 ways:

The example of a ScrollRect on a Canvas:
In both Server and Client I would have the following:
|— Canvas
L—— ScrollRect

when the Server scrolls the ScrollRect, I need to send its normalizedPosition to all the Clients.

Option 1:

• make Canvas and ScrollRect NetworkObjects
• synchronize NetworkObjects:
  -- on Server: AddListener to ScrollRect.onValueChanged, which would update a NetworkVariable<Vector2> ScrollNetworkVariable
  -- on Client, listen to that NetworkVariable changes: ScrollNetworkVariable.OnValueChanged += (..., Vector2 currentVector2) => { ScrollRect.normalizedPosition = currentVector2 }

problem:
this requires both Canvas and ScrollRect to be NetworkObjects, which means I need to Intantiate() and Spawn() them separately one by one, and then re-parent ScrollRect.transform.SetParent(Canvas.transform). This is already annoying, but also ScrollRect’s RectTransform gets broken in the process of re-parenting, because Unity UI changes its coordinates before I reparent. This principally sucks because there are no nested network objects in Unity, and therefore this Instantiation+reparenting needs to be done.

Option 2:
Canvas and ScrollRect stay just regular GameObjects.
I add some “Synchronization Manager”, which does the following:

• ScrollRect.onValueChanged emits a Vector2EventSO called OnServerScrollValueChanged
• SynchronizationManager (is a NetworkObject) has a Vector2EventListener, which, if (IsServer) — listens for the OnServerScrollValueChanged event, and then updates SynchronizationManager’s NetworkVariable<Vector2> ScrollNetworkVariable
• SynchronizationManager’s if (IsClient) subscribes to ScrollNetworkVariable.OnValueChanged , and when that changes, it emits a different event called OnClientScrollValueChanged
• Client’s ScrollRect has a Vector2EventListener, which listens for OnClientScrollValueChanged, and then updates the Client’s ScrollRect.normalizedPosition based on the value it receives

problem:
I have this “retranslator/synchronizer” that creates a large chain of actions (Server ScrollRect Emits event —> SynchronizationManager (Server) Listens —> SynchronizationManager updates NetworkVariable —> SynchronizationManager (Client) Listens for NetworkVariable —> SynchronizationManager (Client) Emits event —> Client ScrollRect Listens)

I'll appreciate any comments on these 2 solutions, or a different one altogether, since I might be thinking wrong about this whole concept

hi, im going to start a game that uses networking with 2-4 players, should i use Photon pun or fishnet, or something else, thanks

bruh

[glad birch]

I'm not sure if this is right section for this, but I want to be able to catch network connection issues in my application and bring up a popup to notify the user, but in the editor when ever i get a connection error unity closes. Has this happened to anyone, its only really started a few weeks back.

I was building the external api so I didn't have time to check it out anymore. As this haven't happened to me in the past i'm not fully sure where to start. I am using 2019.2.15f1 (I kept using this version because this is an old project that we're working on).

The built out project show the connection error, but inside the editor unity just closes.

[zinc marten]

I'm currently developing with Relay and Netcode for gameobjects (Both are unity's brand new multiplayer solution which came out of beta a few months back). I wouldn't recommend it that much especially if you are brand new at networking because the documentation is poor (Except if you want a very basic result) and there are next to none tutorials about it. Although it is an interesting solution and I can see it catching on in the next few years. @limber sparrow

Question.

Hi guys, I'm create a multiplayer pacman.

is it possible to bring network netid to another gameobject transform? Coz that's not local which mean unable to drag and drop it.

My aim is to make ghost will detect the player once they join and chase them.

Welcome for any suggestion. Tqvm !!
Here is my code.

public class Ghost : NetworkBehaviour
{
    private GameObject pacman { get; set; }

    public Transform target;
    public Transform target_Mirror;

 private void Awake()
    {
    target_Mirror = Instantiate(pacman.player_Mirror);
    }
}

public class Pacman : NetworkBehaviour
{
    [SyncVar]
    public Transform player;
    public Transform player_Mirror;

 private void Awake()
    {
        player_Mirror = GetComponent<Transform>();
    }
}

I unable to perform the function in Ghost script (awake part)

[regal karma]

I think I encountered a basic bug in netcode for gameobjects, if someone could confirm before I open an issue, as it's fairly straightforward:

• start Server
• start Client (connect to Server)
• Server: spawn Canvas -> canvasInstance
• Server: spawn Image -> imageInstance
• Server: imageInstance.transform.SetParent(canvasInstance.transform, worldPositionStays: false)

result:
On Server: imageInstance is a child of canvasInstance with correct UI coordinates
On Client: imageInstance is a child of canvasInstance with incorrect UI coordinates, which would be result of worldPositionStays being set to true
Additionally, a warning is produced on both Server and Client:
Parent of RectTransform is being set with parent property. Consider using the SetParent method instead, with the worldPositionStays argument set to false. This will retain local orientation and scale rather than world orientation and scale, which can prevent common UI scaling issues.

who here know how to make an object disconnect you from the server then reload the server and make you join back the server? and when you grab the ball it doesn't end up disconnecting you
im using photon btw and unity vr

[unreal token]

Does anyone know where to find good info comparing photon fusion netcode mirror and just all the possible multiplayer networking possibilities in Unity?

[austere yacht]

there is no way to make a meaningful comparison without looking at them through the lens of your specific project

so best make a list of what you need and check which of them support those things (stuff like server authority) so you can eliminate those that are incompatible with your goals and then read the docs and talk to the communities to see which one seems more fitting. You are gonna marry that library for the project, so you probably don't want second hand info and a casting show to find the right match.

[velvet sonnet]

Did you turn off Scene Management on the Network Manager? I had this exact issue, and turns out that if you disable Scene Management, your level cannot have any pre-existing Network Objects inside the level, the Network Objects must be spawned in manually after the level loads. This means any script that inherits from NetworkBehaviour is a NetworkObject

And I got that exact error message when the client tried to join the server with Scene Management off, except my hash was a different valu

Anyway, I gave up and used LiteNetLib instead. Much better. You need to manually spawn and sync stuff between server and client, but the code is much more light weight, and easy to use. I'll be honest though, the Documentation for LiteNetLib is kind of barebones... no real descriptions, just lists of commands

I am trying to use steam credentials to log into mirror

I can get their user name with this command, auth.loginAccount = SteamFriends.GetPersonaName();

I was hoping SteamID would handle all account info, but I don't know how to utilize it

[hallow junco]

I don't know if you can get the password

Is this there steam account?

[weak plinth]

well I can get the steam id which stores all their credentials

but it's like this huge number

I dunno how to use it

[hallow junco]

Okay

Well if you were able to get there password that's a HUGE vulnerability for steam

Becuase then random people can get random passwords.

[weak plinth]

ya, I don't want their password, per se

mirror wants a password tho

[hallow junco]

Oh

[weak plinth]

in ummorpg you can just make a username and password and it will create an account for you

I'd rather have steam handle all that

steam is way cleaner than ummorpg imo

[hallow junco]

What's ummorpg?

I've never personally used it

[weak plinth]

it's a game engine using mirror that uses about 6000 lines of code to handle 1000 ccu

[hallow junco]

Okay

[weak plinth]

very powerful

[hallow junco]

Well, why do you need the players credentials?

Is it necessary?

[weak plinth]

to make it more convenient for them

I've been working on this project for about 2.5 years and have to login everytime. but now I have a steam license so I just wanna use that to login

[hallow junco]

Oh

I see

So make a login

Then make an auto fill

So you have control but it's still more convenient

[weak plinth]

I just took out the autofill for the name

they still need a password tho

I bet there's a way to transmit the entire steam credentials into mirror directly, I use fizzysteamworks so I'll continue looking through their documentation

[hallow junco]

Okay

Hello guys.
I'm currently looking into the level organization for my game world. Project will stay single player for a while, but I take steps to make every system multiplayer-friendly, so I don't need to make massive overhauls in the future. And I want to make game world level traveling compatible with multiplayer. I read that unity doesn't support multiple scenes running serverside, with players traveling between them independently of each other.
What would be the best architecture for a game with several levels that allows players to be dispersed throughout all of them simultaneously ?

Initially I planned to make a separate scene for each of the levels, and pass the world model and the player between them. But seems like this approach would require some serious overhaul for multiplayer to be added.

It forces the children to expand passed the designated size

I think

Pun or Fusion. Fusion you can use a [Networked] variable but Pun honestly idrk, you could get the “Player” out of the OnPlayerJoined callback, and directly send an rpc to that player with you health

[jolly wadi]

Inputs?

Very broad

Like gameplay inputs like shooting?

[open path]

Like key presses.

Specifically, I am having two players, in a rhythm game, play different parts of a track at the same time in a cooperative manner. How would I have the players sync each other's inputs?

[jolly wadi]

Yes

If you send it in the csllback

Callback

Not at the start of your game

When a player joins

Send it directly to that player so they are up to date

No

Each player rpc them the health of themselves

No

That’s why fusion is predominatly better

20ccu and then payed

Same as PUn

But steeper learning curve

If you have barely started networking

Then I recommend switching

[jolly wadi]

Sort of, but with net variables it doesn’t require any other work, and player props it requires extra complicated code

[terse idol]

Hi, I've made an online fps game using photon and for some reason Joining someone else's lobby only works if both players have the game open, for example if someone hosts a lobby and the other person didn't open the game yet. once opened he can't see the lobby

how can I fix that?

[robust cypress]

Photon have multiple services they offer, which vary in functionality, your problem sounds like you are only listening for games that are being created, when you should be asking the server for games that already exist

[night thunder]

How can I access the Network Transform from the current Netcode for Gameobjects version by a script? GetComponent<XXX>() does not seem to know Network Transforms as a valid component even if that component is on that object

OnNetworkSpawn is clearly valid so the Netcode libraries are accessible

[plush swift]

Hi, I am trying to connect to a TCP server (written in Java) with TcpClient and receiving data in a thread. When the data is received, I invoke an Action and try to change the transform of a UI Button. When I try that, I receive an exception saying get_transform can only be called from the main thread. How can I overcome this situation?

[sinful harness]

is there too much of a difference between networking solutions that makes one better than the others, or is it all based on what you're trying to make?

[spring crane]

That method is coming from inheritance, so you aren't necessarily including everything you need. Try right clicking on the type and seeing if quick actions and dig up the namespace for you. Alternatively check the documentation to see which namespace it's from.

[spring crane]

There are engineering differences, but often they also are targeting different use cases. For example, Photon Fusion, Photon Quantum and SpatialOS are used for different purposes.

[night thunder]

I will try that, although it would be absolutely baffling to me if a Network Transform is not included in the standard Unity.Netcode import, which should include everything you need for multiplayer especially something that essential

[night thunder]

The documentation mentions something about a ClientSide Network Transform which I supposedly can add via a Git-Link, but if I do, nothing happens... The package manager does not download/import it

[sinful harness]

ah i see. Im just trying to figure out which multiplayer networking solution i should use for my game, in which each player has their own playspace (they dont share the same playspace) and they can see the playspaces of all other players in a match

so i just kinda need help in finding out which one would be best suited for my needs

[pseudo reef]

Hello all, fairly new to Unity, been using it a few months for taking some general gaming development classes for my graduate degree. I've been tasked to create a game that I have pretty much completed, but I'm having issues with mirror networking. It's a basic PONG game, and all I want to do is synchronize the "score" of when a ball hits the opposite wall (goal), it updates the text values on both server and client. Currently I can only get it to work on server. The mirror networking documentation is a little confusing to me as I'm a beginner. I was wondering if anyone would be willing to help?

[fringe pasture]

anyone know how to make or a tutorial to make a loading bar for the progress of this script

    void Start()
    {
        PhotonNetwork.ConnectUsingSettings();
    }
    public override void OnConnectedToMaster()
    {
        PhotonNetwork.JoinLobby();
    }

    public override void OnJoinedLobby()
    {
        SceneManager.LoadScene("MenuM");
    }

[woeful shale]

Greetings everyone, can somebody show me how to add a player prefab through code? The only way to do it that I'm seeing in the documentation is through adding it in the inspector, and I'm looking for adding it through code.

I'm using NetCode for game objects package

[quasi jetty]

what happen to netcode cant find?

[dense tartan]

Does anyone know any good tutorials for setting up a lobby system for physics games in Mirror - apparently the process is different for 2d and 3d games

I am trying to activate a panel with Unity's new UI, but this panel to be active only on the screen of the player who triggered it and not to the others. I am trying to use photonView.isMine but it is not behaving as it should.

[thin jolt]

hey i need help with something its urgent. so if anyone here knows photon i was using it it was working fine untell i did something that broke photon its not working anymore and my game has been broken for days now. and the people that play my game are very sad so i need this fixed really fast, so does anyone know photon to help me?

[olive vessel]

Rather than rambling on and on, you could just ask the question to get a faster response

[thin jolt]

-_- true

[severe fable]

When using the Netcode package I have an empty object with NetworkManager component. I then have a few UI buttons with script attached and I'm using NetworkManager.Singleton.StartHost() and NetworkManager.Singleton.StartClient() to connect. How do I listen to NetworkManager events? For example I want to have a UI script which listens for every time a client connects so that it can update/display the user counter.

[austere yacht]

Use sync/network variables that automatically propagate their value to late joiners. Absent those you need to build a system to effectively replicate their behavior by hooking into the client-joined event on the server with everything that has state that needs sync

[keen lotus]

Hey i have a problem player syncing just dont work
i have tried multiple tutorials but they all say the same
its the same with the Photon Transform view and without it
Maybe someone can help 😦

[glossy ledge]

Hey folks!

Trying to plan out a strategy for making Cross platform between VR and PC happen. Not an overly complex project, just a simulation of an environment for users to explore. Does anyone have experience with making this happen? Will more than likely be using Unity with Photon as we have experience with it.

I can't imagine it being too different from a standard multiplayer setup, and is more local checks to see what platform then translating data correctly. But very open the idea that I am completely wrong.

[muted wolf]

I am having a problem in my mp game players are lagging not a lot but a little bit I'm using PUN 2 free

[austere yacht]

subscribe to the changed-callback/-hook of those syncVars/networkVars

[muted wolf]

Anyone knows how I can fix this?

[austere yacht]

photon is a company, do you mean PUN ? if so, why? and maybe use something that supports what you need.

photon fusion, mirror, netcode for gameobjects, fishnet, ... lots of options

who told you to use PUN? how did you find it?

photon is a company

not a product

[muted wolf]

Anikki cloud you maybe help me if you know how to fix it I'm desperate

[junior aspen]

is there an event that gets triggered when connection happens

like when connection to server is approved

[olive vessel]

I imagine whatever networking library you use has this yes

[junior aspen]

oh yeah I'm using netcode

I tried to look for it

couldn't find the event

or at least name of it

[olive vessel]

Called on the client or server?

[junior aspen]

client

when client's connection is approved to server

[olive vessel]

There probably is, you might be best asking in their Discord, it's pinned here

[junior aspen]

oh alright

thanks!

[modest current]

If i call my command it just cuts the client
does anyone know why
public void updateMap()
{
Debug.Log("Update");
if (!hasAuthority) { return; }
CmdPlaceObs();
}

[Command]
public void CmdPlaceObs()
{
    Debug.Log("Cmd");
    RpcPlaceObs();
}

this is the only code that pertains to it that i can think of
the line to call gets caled
and then the client ends before Cmd is printed?

[muted wolf]

Anyone please?

[still hare]

Assets\Script\Launcher.cs(21,26): error CS0115: 'Launcher.OnJoinedLobby()': no suitable method found to override

how i can resolve this?

[severe fable]

I'm having a hard time understanding how I would have a NetworkVariable of type List<MyClass> (I can't really understand the docs: https://docs-multiplayer.unity3d.com/netcode/current/basics/networkvariable) Can anyone give me a simple example of how I can store a List in a Network Synced variable? (In my case I'm trying to store a list of players)

[austere yacht]

You need to implement it yourself or use https://docs.unity3d.com/Packages/com.unity.netcode.gameobjects@1.0/api/Unity.Netcode.NetworkList-1.html

[severe fable]

When I try to use NetworkList<Player> I get this from my IDE: The type 'Structs.Player' must be valid unmanaged type (simple numeric, 'bool', 'char', 'void', enumeration type or struct type with all fields of unmanaged types at any level of nesting) in order to use it as a type argument for 'T' parameter...how can I get the list to work with my own struct instead of just simple types?

[austere yacht]

they must be structs (afaik) and contain only primitive types, you cannot sync references, which is what that error message says

if you want to sync more complex structures (with references) you need to invent a way to do that yourself. I think NetworkObject references can be sync'd so thats maybe the part you have to leverage if you don't want to create custom messages.

mind that "Netcode for GameObjects" is a mid-level API, as such it does not aim to provide you with readymade stuff that is only useful for a specific use-case or type of project, so things like this are left for you to implement as they are fairly specific to each project.

[severe fable]

I see; I'm basically a noob trying to make a game which involves both local and online multiplayer (ie you might have 2 controls on 1 PC and then 2 on another PC and all playing together). Plus you don't control a specific character, you can switch between characters. It seems like it's going to be hard going.

[crystal sand]

how can i destroy player who collides with that object

[hearty dock]

With the Destroy function

https://docs.unity3d.com/ScriptReference/Object.Destroy.html

[fallen prairie]

Have a 4 player Mahjong game, for multiplayer play Im thinking of using a server and using Go to write the match making game controller code. Is this a good idea?

[hasty hinge]

Im using Netcode for Gameobjects right now, and for my NetworkManager I tried changing the IP from the internal feedback ip to my own so I could have other people connect. However, I'm now unable to connect to a server/host from a client, but if I use a host it works by itself. Any ideas?

[austere yacht]

does your LAN forward public requests from the internet correctly to the machine that acts as server and on the correct port? afaik in NFG your server needs to know its own IP to respond to requests, if you want your server to respond to all IP addresses put in 0.0.0.0

[hasty hinge]

I'm not sure, but if its any help I am able to host servers from my computer normally.

[austere yacht]

what kind of servers and what does "normal" mean?

[hasty hinge]

Should I put 0.0.0.0 as the normal address IP?

and for that question, Im able to host a minecraft server with no problem

[austere yacht]

0.0.0.0 means "all addresses" by convention

[hasty hinge]

yes but do you mean that for the "address" or "server listen address" box

[austere yacht]

does minecraft use a relay service?

[hasty hinge]

not sure, but im using unity transport not relay unity transport

[austere yacht]

maybe read this part of the docs https://docs-multiplayer.unity3d.com/netcode/current/learn/listen-server-host-architecture#connecting-to-a-listen-server

[hasty hinge]

just for reference, this is what my Unity Transport component looks like

i blocked out my ip, but its the actual ip clients would connect to (i assume)

[hasty hinge]

ill look into this more tomorrow, i cant rn, but i appreciate it

[austere yacht]

idk for sure what the difference is, there was only one field last time i used it, probably combining the two

i suspect the "server listen address" is relevant only for a server/host

"address" would be the address your client connects to

[hasty hinge]

thats what I thought

[austere yacht]

are you able to connect on your LAN?

[hasty hinge]

I think the server listen address is what the server itself it supposed to listen to (?), but when I set it to my actual ip it failed

[hasty hinge]

wdym by this?

like on my own machine?

[austere yacht]

your from your local network

not from the internet

[hasty hinge]

i cant even connect between the server and client im running on the same machine

[austere yacht]

then you probably have specified the wrong addresses / port

[hasty hinge]

maybe

[austere yacht]

there are only so many options that would make sense

[hasty hinge]

it works with 127.0.0.1 locally, but i assume that wouldnt work for anyone else

[austere yacht]

try your LAN IP

192.168.x.x usually

or 10.10.x.x

and make sure the port is correct on both ends

[hasty hinge]

I can try that, but then there must be somewhere else to specify an actual IP to connect to right?

the port is almost certainly correct

[austere yacht]

also make sure the server actually starts (it can fail if the port is blocked)

[hasty hinge]

I assume the server is starting, since the host is able to work on its own

[austere yacht]

you should assume less and confirm more

[hasty hinge]

yeah

im going to add some logging tomorrow to check all this, but rn its 5:00 am

[austere yacht]

then maybe ask again tomorrow

[hasty hinge]

i was able to try the lan ip, and that works

but again, I don't see how it would be able to work for anyone else, seeing as I havent put my IP anywhere else in unity/the code

[austere yacht]

did you read the docs i linked, its all explained there

TLDR: you can't just have someone from the internet connect to your server, you need to configure your network properly or use a service that eliminates the need

[hasty hinge]

yeah, you need to port forward, but i've done that and I know i have ports open

it might be a firewall thing, but if so Ill have to figure that out tmr

but thanks for the help today

[weak plinth]

Question when making a multiplayer game using steam, do I have to use mirror? why? and why does mirror do since steam provides the server?

[digital stag]

Hi is it generally OK to bombard a server with lots of requests and then await all of them to return or should you stagger requests, even do 1 at a time?

[still hare]

no? steam and mirror are completely unrelated, and steam does not provide game servers

mirror just makes networking in Unity easier to do

steamworks allows access to the steam api to invite friends, display active servers, create lobbies, etc

[weak plinth]

sorry i was away and yes... I understood it after research for an hour

[edgy tiger]

Looking for some help with PUN 2, is anyone here familiar with it?

[weak plinth]

very basic unity code question - how do I say "if this is a player, but not THIS player" ? (like for multiplayer)

[austere yacht]

if (someObject.TryGetComponent(out Player player) && player.SomeIdProperty != excludeThisID) 
{
    // do something to player
}

[muted wolf]

What do you need help with?

[edgy tiger]

How would you go about sending audio clips over an rpc?

[austere yacht]

Assuming regular unity multiplayer context. You would not do that. You‘d send maybe the info where to download or stream them and then process that info in a separate system. If you had to do it, you’d serialize them like any other data.

[edgy tiger]

Hm, I might have to reconsider how I handle sound syncing then

[austere yacht]

this is because streaming data like that saturates the servers bandwidth immediately, degrading all other sync (of gameplay) and it does not scale.

[edgy tiger]

Yeah that makes sense

They are large clips

[austere yacht]

are they dynamically created?

[edgy tiger]

No

[austere yacht]

You would not even send the clips to another method if it were a local thing without networking

[edgy tiger]

It's from a gun class which pulls it from a scriptable object

Can't have a photon view because it's a parent of another object

So I'm a bit stuck on how i could sync it

[austere yacht]

then everyone already has the sound. Only thing you need to sync is which one to play

[edgy tiger]

Would you be able to source a photon view from a parent object?

[austere yacht]

or maybe not even that. All clients might just play it in response to an action the sound is already associated with. So you sync only the gameplay action

[austere yacht]

Sorry, can’t help with PUN

[edgy tiger]

It only syncs the damage taken on the player that is hit

[austere yacht]

Photon is a company, not a product

[edgy tiger]

Apparently pun is deprecated now

And i need to move to fusion

Thanks though

That was helpful

[zinc marten]

does anybody have any experience with VR multiplayer? Netcode and Relay in particular

Im trying to sync the head and hand movement over the network but since it is a package script i cant really edit it. Any ideas?

[elfin token]

How can I edit an instance in real time so it syncs to all the players in the same build? Like if I spawn something in my editor instance how can I make everyone to see everything I do in real time from their builds, even if an object is not actually in the scene? Like those sandbox games that spawn things and it does for everyone.

Ping when reply pls

[elfin token]

I'm using photon

[halcyon heron]

Should I use Mirror or Netcode or some other network library for a simple pvp/pve (cube enemies) game?

• Only physics the game contains is box colliders
• I have no experience in networking

[zinc marten]

@halcyon heron I'm learning Netcode for my job, I gotta say tutorials are pretty rare to find given the full release came out a couple of months ago. Documentation is okay, covering the most basics of stuff without many examples. I would say find a network library that has more tutorials if u are a beginner. Its not like Netcode is terribly hard to implement. Its fairly simple and using it alongside with relay is pretty flawless not gonna lie. But yeah documentation and tutorials are my main issue with Netcode, especially now that Im doing an online VR prototype... there is almost nothing online.

Hi! I'm trying to make a multiplayer 2D top down game using Photon, but I have some issues. My game has a soccer ball and I can't make it so it doesn't bug on different clients, can someon help me?

using UnityEngine;

public class BallMove : MonoBehaviour
{
    private Rigidbody2D rb;
    private Vector3 lastVelocity;
    public float speed;

    private void Start()
    {
        rb = GetComponent<Rigidbody2D>();
    }


    private void Update()
    {
        lastVelocity = rb.velocity;
    }

    private void OnCollisionEnter2D(Collision2D collision)
    {
        var speed = lastVelocity.magnitude;
        var direction = Vector3.Reflect(lastVelocity.normalized, collision.contacts[0].normal);
        rb.velocity = direction * Mathf.Max(speed, 0f);

    }
}

[pulsar lion]

you could delete the script on the client side with something similar to

private Start()
{
  if(!isServer)
     Destroy(this);
}

and then just use photon's version of a Network Transform component to update its position and rotation.

[tranquil hull]

Hi guys, I have a question here.

when someone gets a chance, I have a couple problems in changing values and deleting objects for all clients with photon Pun2, I cant seem to find what is wrong, the bounds dont change when the rpc changes them, the flag dosent get deleted when a client other than master collids with it, and when all the cops get deleted it somehow triggers one more to spawn, I cant find out what is causing it, any help would be nice
my scripts: http://pastie.org/p/5L1OHMmjdujod6HMueOBfg http://pastie.org/p/67rBDJaDbpGZDDY5SVtbst

[wide girder]

Might want to add some debugs to see if the RPCs are getting called on the client and on what objects.

[fringe pasture]

i did and what it said is that the bounds had changed from 25 to 50 but i still am confined to 25 by 25, and for the objects being spawned i dont know what causes it still nothing sets spawn enabledd and spawn cops to true when the host goes to lobby or when everyones out, and i know the problem with the flag and im trying to figure out how to use the ownership transfer stuff i need to do

[wide girder]

Make sure to output the object name with the other info. Seeing how you have several, the changes might be applied to a different object than you expect.

Otherwise, I can only guess that it resets locally to the other value. Might want to turn the field into a property and print log in it's setter to troubleshoot that.

[fringe pasture]

well ill try

how to check if a player connected to the room in photon

[safe loom]

is canvas, camera, audio, listener part of the prefab player in netcode

i mean

or i need it to be out of it parent to be local because i think this happens when gameObjects are out of player prefabs they turn into local

[still hare]

not sure what you are asking exactly, but no, you generally shouldn't have your camera or audio listener as part of your networked player prefab

if you have all of those on the prefab, you will have to manually remove them for every other player when they spawn in

[safe loom]

ok thx

[fringe pasture]

when someone can help, i am slowly fixing the problems i said w hile ago, I found the issue for the flag destroying and i found a diffrent way that destroys the flag but i still get this error i know it functions but it would be nice to fix this error

I have a NetworkManager prefab setup. Normally when playing the game you'd go through various menus, hosts/clients would get started and then carried over to the next scene. However when developing I want to be able to jump straight into a scene. So I have added the NetworkManager prefab to every scene; but I want to add a script to it so that on Awake it checks to see if the NetworkManager already exists (if so use existing one) and also check to see if we've jumped into game midway though and need to start host. Here is my script (below). The problem is that Unity is saying that I cannot add a NetworkBehaviour script to my NetworkManager....so what should I do to make this work?

using Core;
using Unity.Netcode;
using UnityEngine;
using UnityEngine.SceneManagement;

public class NetworkManagerScript : NetworkBehaviour
{
    public static NetworkManagerScript Instance;

    public NetworkVariable<NetworkString> thescene = new NetworkVariable<NetworkString>("MainMenu");

    void Awake()
    {
        if (Instance)
        {
            DestroyImmediate(gameObject);
            Debug.Log("NetworkManager was already started in previous scene");
        }else {
            DontDestroyOnLoad(gameObject);
            Instance = this;
            if (SceneManager.GetActiveScene().name != thescene.Value)
            {
                Debug.Log("We have jumped into the game midway so start the host");
                NetworkManager.Singleton.StartHost();
            }
        }
    }

    private void Start()
    {
        thescene.OnValueChanged += (value, newValue) =>
        {
            CheckScene();
        };
    }
    
    public void CheckScene()
    {
        if (SceneManager.GetActiveScene().name != thescene.Value)
        {
            Debug.Log($"Load new Scene: {thescene.Value}");
            SceneManager.LoadScene(thescene.Value);
        }
    }
}

(photon pun2) i have an rpc called RPC_ChangeBounds, everytime the host hits start or lobby they call the rpc, my problem is that the other clients bounds dont change, the debug i put in the rpc itself says the x and z bound are 50 but the bounds somehow are still 25 which is proven when i try to go past -25 or 25 on the x or z and it dosent let me and the debug there says its 25, I am truley stuck and cant find the cause. any and all help is appreceated.
my code: http://pastie.org/p/1RlYX9gJCvPm8mrBC9pTrq
i forgot to mension that with the execption of in one function and the rpc, i have no other places that the bounds get set and yes ive tried taking out the part where they get set in the one function and it had no effecthave some rpcs that wont

[steel crow]

I building a multiplayer pong game and need help with a thing. The ball isn’t on the same position on client and host, the client is behind. How can I solve the problem?

im just making a new script for my player, the old one is broken, but i still cant change a variable for all clients, anyone know how i can do this (photon pun 2)

[inland pier]

Command Function System.Void ReadyUp::CmdReadyUp() called without an active client. what is this

[inland pier]

bro does anyone know how to make ready up thingy in unity pls help

[olive vessel]

This looks like you tried invoking a Command on the server without even being a client

[inland pier]

bro idek what that means

[olive vessel]

It's pretty self explanatory, you must be a client on a server to invoke a [Command] on the server

[inland pier]

what if i am host

[olive vessel]

You must not have been hosting at the time

But it's the same explanation, you're both the client and server

[inland pier]

i still dont get it

[inland pier]

but what is an rpc and can i use for this

[olive vessel]

A [Command] is literally an RPC

[inland pier]

oh

welsh cow do you know photon at all

[heavy zinc]

hey do you know any good tutorials for unity netcode for beginners? except docs

[elfin token]

How can I edit an instance in real time so it syncs to all the players in the same build? Like if I spawn something in my editor instance how can I make everyone to see everything I do in real time from their builds, even if an object is not actually in the scene? Like those sandbox games that spawn things and it does for everyone. I'm using photon. Ping when reply please.

[tranquil hull]

Anyone know what is <spriteRenderer>k__BackingField ?

[austere yacht]

artifact of serializing an auto-property iirc

[tranquil hull]

Ermm okay thanks
Let me go google for this 🙈

[spring crane]

If simply adding a gameobject with a network identity component doesn't work, you likely need to tell the networking system to spawn the object for other clients. These things should be laid out pretty clearly in documentation

[safe loom]

how do i convert

this?

[still hare]

it probably has a .value or something

try putting a dot and seeing what your IDE gives you as potential options

[sleek zealot]

why do i get these errors after i install "Photon Unity Networking Classic" to my unity project?

hello?

[sleek zealot]

i just deleted it now

[safe loom]

what is this?

[haughty heart]

Exactly what it says, any method marked [ServerRpc] must have the name of the method end with ServerRpc.

[safe loom]

i didnt understand

[haughty heart]

As in, you still don't understand?

[safe loom]

i dont speak english very well

what i need change

?

[haughty heart]

Because you have UpdateClientPositionToServer() marked with [ServerRpc] you have to change the name of it to UpdateClientPositionToServerServerRpc()

Which is a little long, but that's what it is

You have to include the words ServerRpc at the end of the method name, is what it's telling you.

[safe loom]

in the update?

[haughty heart]

The name of the method, which of course includes any reference to it.

[safe loom]

oh thx

i think worked

is returning me thix exception

is this because of my variable ?

write permission

?

the right way to transform a networkObject is transform first in the client and send the network variable position to the server and server to all clients - owner (you)

or client dont transform it and just send the network variable position to the server and the server transform it in all clients including the owner (you)?

[hybrid mural]

Hi, sorry, I didn't want to interrupt anyone's question or anything, I've just been struggling with some problems implementing Photon and I figured I could come here for some guidance. Basically, I'm trying to create a 3d ultimate frisbee game, but having the frisbee successfully go from one owner to another and back again has proven to be tricky. I'm able to successfully throw the frisbee from the host player to the other player, but when the other player throws it back, it ends up in a totally different position in both instances of the game. I've basically just been making random minor adjustments for the past few days to address the problem, but honestly I'm pretty stuck. If someone could provide me with possibly a blueprint for how they would approach this problem, or this idea in general (throwing an object back and forth in Photon), that would be really, really helpful. I can provide code also but I've been really slacking on readability and the general tidiness of the code tbh in an attempt to get everything to work. Thanks!

how to instantiate GameObjects in multiplayer netcode?

[austere yacht]

https://docs-multiplayer.unity3d.com/netcode/current/basics/object-spawning/index.html

[regal karma]

hi,
if, as a server, you subscribe to OnClientDisconnectCallback, and try to check the ConnectedClientsList.Count, you will get a number WITH the disconnecting client still being in the list

so if you had only 1 client, who then disconnects, you will get the ConnectedClientsList.Count == 1 on the disconnect callback

if you run a routine with like 2 second delay, and check the ConnectedClientsList.Count again, it would then be == 0

is there any way to get a callback/event when the ConnectedClientsList.Count == 0, to avoid the ambiguous waiting routine?

(this isn't a bug, since it has been addressed in issue #1156 https://github.com/Unity-Technologies/com.unity.netcode.gameobjects/issues/1156)

#📖┃code-of-conduct Job or collaboration postings go on the forums

[stiff ridge]

I assume you are using PUN 2. I would recommend looking into Fusion, which is our state of the art networking solution.
In PUN 2, one player is the "controller" of any networked object. This client sends where it belongs to. If you throw the frisbee from A to B, you possibly want to pass control to B as well. Else, B can't just tell everyone where the frisbee belongs and this will complicate matters.
In Fusion, you could do something similar and it is better suited for games with physics aspects (such as throwing).

[stiff ridge]

This is somehow an issue of Unity generating the .sln and .csproj files properly. Some Unity versions do this infrequently.
Check if you could update the "Visual Studio Editor" package in the package manager. You could regenerate the files from the panel Edit->Preferences->External Tools. There is a "Regenerate project files" button.

[stiff ridge]

Unity is not deterministic.
Quantum is a deterministic multiplayer engine which runs in Unity (and uses it for audio, visuals, etc). It's a full implementation of predict rollback netcode.
So .. there are options.

[sleek zealot]

oh alright, imma do it in some time, also is there a way i can downgrade a version of a package?

like the pun 2 and photon unity networking classic

[stiff ridge]

The Asset Store only provides a single version of the packages. No way to pick another.
I would not recommend using PUN Classic. Actually, PUN 2 is a bit dated (if usable), too. Of the Photon products, my recommendation is Fusion...

Hi, I made a game using photon engine but only 2 out of 3 of my friends see the room to join it

how can I fix this?

[gritty olive]

I am making a LootLocker Leaderboard. Here's my code

    {
        LootLockerSDKManager.StartSession("Player", (response) =>
        {
            if (response.success)
            {
                Debug.Log("Succsess");
            }
            else
            {
                Debug.Log("Failed");
            }
        });
    }
    public void SubmitScore()
    {
        LootLockerSDKManager.SubmitScore(MemberID.text, GameManagerScript.Score, ID, (response) =>
        {
            if (response.success)
            {
                Debug.Log("Succsess2");
            }
            else
            {
                Debug.Log("Failed2");
            }
        }
        );
    }``` Basicly my problem is I get a "Failed" and if I try to submit a score this error:

[weak plinth]

In your class you could store a bool value on wether of not LootLocker has been initialized properly. Than check before trying to submit your score

[heavy zinc]

hey does anyone got that error? I'm getting it everytime when I want to change scene via server (I can't track where the problem in my code is, because I'm not using "ConnectedClientsList" from network manager)

how can i make a button leave a normcore room?

[tidal moat]

So I follow all the series about steam multiplayer by zyger and I added pause menu with a button to go back to menu but when I try to host lobby again I can't because the first lobby I created still exist.
How can I delete lobby?
I tried Do this

public ulong CurrentLobbyID;
private const string HostAddressKey = "HostAddress";

public void DeleteLobby()
    {
        SteamMatchmaking.DeleteLobbyData(CurrentLobbyID, HostAddressKey);
    }

but it require CSteamID and now ulong

[olive vessel]

Create a new CSteamID(), you can probably pass it a ulong in the constructor

[tidal moat]

This code delete all the loobies in the game and i want the delete only the lobby that i hosted how can i do this

[severe fable]

When using unity NetCode; when I load a scene (using SceneManager.LoadScene) which contains NetworkObject component the network object does not "Spawn" automatically. So I have to add something like this:

        private void Awake()
        {
            if (!NetworkObject.IsSpawned)
            {
                NetworkObject.Spawn();
            }
        }

Is there a way to have NetworkObject always start by itself, without having to do this on every NetworkObject?

[gritty olive]

But I just wouldn't work, right?

I also got this message, but in the tutorial I was told, I should use IOS

[austere yacht]

Use the NetworkSceneManager

[weak plinth]

Not sure what you are saying here sorry. I would check if that sdk support desktop environment or if it only works on iOS itself which could be the case as to why its not initializing for you.

Nevermind I got it working but thx

Hi what do you guys use to read JSON data out of a web request result? Do you use Unity's JsonUtility to deserialize into a class representation or a simple JSON library like SimpleJSON (Bunny83's) or something more complex...?

[austere yacht]

Newtonsoft https://docs.unity3d.com/Packages/com.unity.nuget.newtonsoft-json@3.0/manual/index.html

[digital stag]

ok yeah I have to get onto that but a thread on the forums was discussing issues with different newtonsoft libs. Feels a bit like overkill when you look at the code size

[austere yacht]

That’s a misperception. Especially since it is already part of almost every unity build because everything relies on it

dealing with a HTTP/REST api in itself is the biggest bloat/overkill you incur

Hello, i am using unity netcode multiplayer, and i need to set 2 variables of a networkObject on spawn, and i am actually spawning the netWork object on server side, but when i try to set local variables or networkVariables on it, it never changes

so i need help

i call this spawning function on client side to be done on server side

[austere yacht]

How and when do you check if the values are correct? If the variables don’t change on the server, this code does not run on the object you are inspecting or something else (not in this code) happens between setting the values and you checking them.

You could set the network variables before you spawn the object

[severe fable]

With Unity Netcode is there any built-in way to get a clients ping/latency?

[austere yacht]

you can just send a timestamp from the client in a ServerRPC that immediately sends back the same timestamp in a ClientRPC in which you compare the actual time with the received timestamp

float _roundTripTime;

void UpdateRTT() {
    ToServerRpc(Time.time);
}

[ServerRPC]
void ToServerRpc(float ts) {
    ToClientRpc(ts);
}

[ClientRPC]
void ToClientRpc(float ts) {
  _roundTripTime = Time.time - ts;
}

[wet compass]

are network variables constantly being syncd or only when they change on the server are they reflected on the clients?

(in netcode)

I would expect it works sort of like rpcs, and whenever you set the networkvariable value on the server it does a clientrpc which passes the new value to the clients? I just want to make sure having many network variables that dont change much are not making heavier packets unnecessarily

[safe loom]

hello i am getting missing reference exception when i try to despawn a gameObject from netcode, some help?

i call this function in a client that is not the server

[austere yacht]

on the server you need to assign some network object to the field called networkObject, if you want to refer to the NetworkObject component of the GameObject that your NetworkBehaviour with this method is on, then use the this.NetworkObject property to access it.

I'm having an issue where "Late joining" clients are not getting a synced copy of a NetworkList? They only get synced once the NetworkList has been changed after they join (so they get an empty list as the initial value even though it is not empty)

[haughty urchin]

hey im trying to make player 2 spawn with a different prefab than player one but they both spawn on player 1 prefab can i change this?

[high night]

Id suggest having your player prefab as an empty object with a script

It will be like the players "soul"

It will possess the character and control it

[haughty urchin]

can i PLEASE call you your the first person to try and help me with this

its the biggest yet simple prblem i have

my games already done i just cant set up the second player

[high night]

im going to sleep in a few mins

[haughty urchin]

damn it

well how to do you asign one person that "soul" or script

[high night]

you'd spawn a character for the new player seperately

with an rpc

[haughty urchin]

rpc?

also i dont know how to detect when the second player joins the lobby

[high night]

there should be callbacks for that

something like OnPlayerJoined

[haughty urchin]

wait wait

could i say on player joined make player count 1

[high night]

Or you'd know from the spawning of the player prefab

[haughty urchin]

if player count is 1 spawn second character????

[high night]

yeah

[haughty urchin]

im using photon you think it will still work??

[high night]

you can keep track of joining characters using the callback

this goes for phoron and mirror

[haughty urchin]

im not sure how to use callbacks

[high night]

probably all other options

they are not too different afaik

You should be able to call an RPC method

[haughty urchin]

couldnt i use SpawnPlayers : MonoBehaviourPunCallbacks

[high night]

If you call an rpc in your gamemanager amd your gamemanager inherits from networkbehaviour or its photon equilavent, has the network identity component and all

The rpc you call on servers gameobject

Will be called on clients with same parameters as well

Thats how mp comminication works

[high night]

hmm not sure about that callback

[haughty urchin]

i have to use it yuea

i already know that

[high night]

You should be able to type something like OnClientConnected

or joined etc

[haughty urchin]

are override voids like update voids?

[high night]

In a component that implements photons class

[high night]

yeah

[haughty urchin]

ok then i can finish this

omg thank you

[high night]

yeah

you should also be able to access the clients id somehow

if its 0, you can spawn prefab0

if its 1 spawn prefab 1 maybe

[haughty urchin]

ok ok

[high night]

there should be an id going in order starting from 0

[haughty urchin]

at the start is when player 1 joins

once they join player count becomes one

id someone else joins room and player count is 1 they get the second prefab and position

i just gotta test it now

[high night]

yeah

[haughty urchin]

it just spawned a thousand prefab 2s

[errant crane]

So for work I'm trying to introduce agents to play in place of players when the player count is low.
We are using PUN 2.39, going by the documentation, and I'm kind of at a loss on how to do it properly.
How do I get the Agents to exist server-side and then be shown client-side during play?

Because far as I can tell, PUN2 does not have a method with which to make "fake" players or basically AI players.

[keen pivot]

Hello

how can I make a matchmaking system with photon based on the level of the player

To join people of same level and ability in the same lobby

[stiff ridge]

You could look into using the SQL Lobbies:
https://doc.photonengine.com/en-us/pun/current/lobby-and-matchmaking/matchmaking-and-lobby#sql_lobby_type

[stiff ridge]

Right, there is no bot framework for PUN 2 (Quantum has one but it's likely too late to point out).
In the cheapest case, you'd run the AI on a client. It you just spawn units/characters accordingly, it is not a proper separate connection and player but this leaves room for others to join (as the AI doesn't use a seat in the room).

In theory, you could invest more effort and make AI that properly connects to PUN rooms with separate connections but that will eat CCU and be quite some effort.

To the suggestion is to let one player do more work. Sync which players are faked and let them be controlled by AI running on the Master Client or so.

In this particular case, the master client is a server, so the effort would not be run on an actual players computer

[clear sky]

@olive vessel thank you, but I looking for some information about doing that and don't really find how can I do that 🙂

[stiff ridge]

So you would run PUN instances on servers and make them create the rooms / become the Master Client per room and take over extra duties, yes?
Ok, that's possible too.

[errant crane]

I was told recently that PUN2 is just some prototype stuff and that we won't use it anyway for the product so it seems I don't have to care about it at all hah

I appreciate you wanting to help though @stiff ridge

[stiff ridge]

Glad to read that. It's not our favorite solution anyways. Unlike Fusion, PUN is not built with running on dedicated machines in mind...

[errant crane]

Yeah it would be nice to use Fusion

Though it seems we have some proprietary thing we have to use instead so

I guess we'll see

I'll probably be back with vague questions again in the future, don't you worry

U need the photon view

[little sorrel]

how

[little sorrel]

its there

its ismine

ownership

[karmic dagger]

And the

In the script

Do

And reference the photon view

And called it what ever for example view

[little sorrel]

Im kinda confused

[karmic dagger]

And do if (view.Ismine)

And movement in there

[little sorrel]

why doesn't this work

 
   void Awake() {
        
        if(!playerPrefab.IsMine){

playerPrefab is the photonview

[karmic dagger]

Add me and il help

Or dm

I need help with the thing tho

I have no idea how to do it

How do you set playerPrefab?
If you'd inherit from MonoBehaviourPunCallbacks class, there is a photonView field already, which you can use. It will look up the local PhotonView and cache it.

Can someone recommend a wich networking works the best for the type of game im trying to make ? is a 3d android game wich every person has a character, your own house, social type of game just like "Playtogether" kind of game on android

[woeful shale]

Which is better to use the netcode for gameobjects of unity or photon?

[olive vessel]

"Better" is subjective, you should pick a solution that works for your needs

[austere yacht]

Photon is a company not a product

PUN is only useful for games where you trust all players to not exploit/cheat or where it would not matter

If you want a solid mid level base that you can take anywhere use mirror or netcode

if you want a mmo, just stop now

if you want the fastest way to do a competitive/pvp fps, use photon fusion of quantum

if you feel adventurous (or want to do some deep learning) build your own library on top of ENet or another transport library

[jagged sequoia]

Im so confused. if i want lets say, a game people join in the same world with 300 players lets say. They can go to diferent locations on the map to fish, play minigames, etc. Kinda like club pinguin 3d like , social with games or activities to do in the map, collection of clothes, furnature, etc.

[austere yacht]

How big is your team?

300 people on one server on a shared world is an MMO and it’s 99% likely that you will fail to ever make it work. Especially if you have to ask here how to do it.

[jagged sequoia]

is just me , im trying to make at least the core to test 2 players interact with each other with chat, bubble chat on their heads when they type and then in the map like a river to fish

Just use mirror or netcode

Both can potentially handle 300 players. But it’s very dependent on how you design and implement your stuff.

[jagged sequoia]

Allright , thanks for the info i will check those out

[austere yacht]

mirror has a lot more stuff built in to get you going with non trivial player counts (like interest management)

[jagged sequoia]

Cool ill go for that then

[haughty urchin]

hey i need help with something

im trying to get this button to be instantiated so it will display room names and join on clicking it

but it wont instantiate

the 1st photo is my scipt that instanitiates the room object

the 2nd one is the script that belongs to the room object

[little sorrel]

I am making a game with photon and everything syncs except when I shoot. Bullet has a photon transform view on it and photon view is observing it. Also this only started when I added pv.IsMine though the bullet still instantiates which is the function that is protected by ownership. Also I did make sure I was using monobehaivor pun callbacks.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Photon.Pun;
public class shoot : MonoBehaviourPunCallbacks
{
    public Transform firePoint;
    public GameObject bulletPrefab;
    
    public float bulletForce = 20f;
    public PhotonView pv;
    // Update is called once per frame
    void Update()
    {

            if(Input.GetButtonDown("Fire1"))
            {
                Shoot();
            }
        

    }
    
    void Shoot()
    {
        if (pv.IsMine)
        {
            GameObject bullet = Instantiate(bulletPrefab, firePoint.position, firePoint.rotation);
            Rigidbody2D rb = bullet.GetComponent<Rigidbody2D>();
            rb.AddForce(firePoint.up * bulletForce, ForceMode2D.Impulse);
        } 


    }
}

I'm using Unity netcode and I'm having a problem where I'm checking to see if client is the owner then doing a ServerRPC, such as this:

            if (IsOwner)
            {
                var movement = CalculateMovement(_movementInput, m_Momentum);

                if (movement.DidMove)
                {
                    SendMovementServerRpc(movement);
                    ProcessMovement(movement.Simple());
                }
            }

The problem is that I have another ServerRPC call on a different button to remove ownership. So the server might have already removed the clients ownership by the time the client tries to run the movement RPC....at which point it is correctly being ignored by the server....however the server splits out errors like this Only the owner can invoke a ServerRpc....is there some way to hide these errors...or should i do something else so that these errors don't even occur?

[jaunty yew]

Do you guys know a good tutorial that goes over photon? I want to try make simple multiplayer games

[leaden glacier]

You should go on the Photon website, choose a solution (PUN2, Bolt, Fusion) and pick one that fits your needs. For simple multiplayer games I recommend PUN2 as it is very simple to understand, but it is very old and no longer being updated with new features, although it is supported and works fine with new versions of unity

[jaunty yew]

Thanks!

I'll try PUN2 first

[leaden glacier]

Awesome! If you need any help, consider joining the Photon discord

[jaunty yew]

There is?

[leaden glacier]

yes

[jaunty yew]

I didn't know that :l

[leaden glacier]

I can dm you an invite if you need

[jaunty yew]

Can you, thanks!

does anyone know what the easiest way to implement networking into your game is?

I've found a lot of stuff like mirror but sometimes it works and sometimes it doesnt

I'm looking for something more beginner friendly and easy to work with

[austere yacht]

Networking is not beginner friendly. Mirror is about as easy as it gets without being oversimplified.

[pure acorn]

When networking a item that moves, how do you keep everyone on said item?

[little sorrel]

Can you put a photon game on the web

[raven halo]

Hi everyone! Is anyone familiar with Netcode? I've been learning it for a couple of days now and would like to understand better why would someone use [serverRpc] instead of setting the NetworkVariable`s permission to Owner, and just setting the value on the client?

At first I thought that NetworkVariables wouldn't be propagated to all clients if set by the client owner, but I've tested with three, four clients and it still seems to sync fine.

Here's a code snippet to illustrate my question.

[spring crane]

Photon Fusion somewhat recently got browser support and PUN has always had it AFAIK. Photon Bolt and Quantum I'm not so sure about.

[trail parrot]

Halo. Maybe a noob question

Unity runs on 1 thread, but what if i run multiple unity instances? Will they all run on the same thread, or will each instance take different thread?

So yeah basically should my server run multiple instance, or just 1 instance with many room sessions?

I guess a factor is, how much processing each session needs

I only need to host 2 heavy sessions, and the only benefit i can see to combine them in single instance is i can communicate between the 2 individual additive scenes from within 1 instance (i need this)

In the future ill definitely separate them, and have them comm via just Rest
But im just making a prototype for now, so i can ignore scaling

[pallid mulch]

@trail parrot Thread != core
So if your server has to run Unity then multiple instances would be better 🤔 I think.

[frank meteor]

If I just need a networked messaging system for transferring data between Unity and a different program on the network, should I just use C# networking sockets, or is it still worth getting a networking solution? I just need to read and write streams to a network port like it were a text stream. Would I start to run into issues if I tried to just handle it myself?

[somber drum]

I think mirror would be worth a shot since it's free and very open-ended with how you use it @frank meteor

various community made transports etc

[spring crane]

I see very little reason to use Unity if all you end up using from it is the .NET runtime, especially considering the progress happening in newer .NET versions. 😄

[frank meteor]

I'm interfacing with a java program through network messages to control a unity program. Basically taking a bunch of math from a java based simulation program and rendering it in unity with objects and whatnot. It's not connecting separate unity applications so I don't need a full multiplayer suite with things like player ownership, I just need to pass data to and from the Java program on the network

[austere yacht]

does it involve the internet?

[frank meteor]

Potentially

But the most common use case is localhost

[spring crane]

Just opening an UDP or TCP socket on both Java and C# side and sending data through it shouldn't become a problem, though if you are targeting a lot of platforms, there can be platform specific challenges. I don't think it would be an issue on desktop platforms though.

[austere yacht]

if you can exclude the internet, i'd just roll my own solution for that specific app with UDP (if its realtime)

[frank meteor]

Yeah, that's what I've ended up doing. It's desktop only.

[amber void]

i implemented photon into my game to make it multiplayer but when i have two players in a game, it moves the wrong character even though i am focused on my chosen screen

it only started doing this when i added my character movement script

here is my character movement script

another weird thing that it does is that it also moves my player's camera based off my normal mouse movements irl, but doesnt actually show it on screen

[spring crane]

Hi,I have some problem now, if I want to creating metaverse multiplatform webGL version, what service I can use for networking?
pls, suggest me.

[worldly drift]

Can someone please help me with this problem i am having with Photon puns RPC? https://hatebin.com/wpyawfcaqt It gives an error

[clever verge]

Hello, I have a question about the Boss Room sample

can it be converted into a server client model?

I mean hosting it using Multiplay that is

The rep says it uses relay

Does the networking logic remain the same?

Only the connection to the server changes?

[hoary nebula]

whats the closest network to unet that i can use on 2021.3.9f1

[olive vessel]

Mirror

[split gyro]

hey! so I am trying to make an online 2d game, I have the spawning working but I am using a CM vcam and I have no idea how to make it so when each player spawns in they have their respective camera

I am putting my player in an empty gameobject and putting all the camera stuff in there to see if it would work

Actually

I think I got it to work

ok

so now I am having trouble with priority

they are both set to one when spawned but idk how to make it so the camera focuses on the character that it spawned with

[elder umbra]

hey

so i just did the exact same thing, here is how i did it

[split gyro]

ok

and if I put this they will have their seperate cameras focused?

like the priority

[elder umbra]

look, there are two camera in a scene, 1 of A and 1 of B. If B is the owner then A's Vcam gets disabled so both cameras now follow the active one.

[split gyro]

eh

I wanted them to follow seperate objects

it is going to be an online game

[elder umbra]

ya

[split gyro]

so A follows player A and B follows player B

[elder umbra]

that is what will happen

[split gyro]

ahh

ok

I see now

thanks!

[elder umbra]

any time

@split gyro it will work like this:

[split gyro]

Perfect!

why doesn't my bullet sync across clients
Component

[amber void]

i imported a flashlight asset into my project but the flashlight and the light emmited dont show up on the other persons screen (im using photon btw)

(PUN, to be specific)

[spring crane]

You need to sync that with other clients through one of the methods present in PUN. If you don't know what is syncing something, then it probably isn't, and you need to do it yourself. https://doc.photonengine.com/en-us/pun/v2/gameplay/synchronization-and-state

[elder umbra]

Hey,

Im trying to make a multiplayer car game. I initialize the car controller from the Network manager. and here is the script for the car controller:

but only the host can control the car for some reason

the clients wheels turn and all but it doesnt move.

this is the prefab:

[elder umbra]

anyone?

[elder umbra]

😦

if I turn off interpolate in the network transform, it starts moving in the client window but the host player does not update in the client window

[thorn crown]

For A* and mirror is there any plugins that would sync movement or do I need to all movement events on the master client?

Or just say fuck it and let each client handle their movements?

[vestal echo]

Anyone know how to use Unity Gaming Services Lobby with dedicated game server instead of relay?? Im desperately searching for tutorials but theres none, almost all tutorials using relay instead of dedicated server

[little sorrel]

why doesn't my bullet sync across clients

Please help

[split gyro]

@elder umbra it won't let me use Unity.Netcode or NetworkBehaviour
