[open valve]

I don't want to make a whole custom scene management solution and I don't want to modify the netcode library... so I made this dirty fix (added to Awake on my network objects script)

if (!NetworkManager.Singleton.IsServer && !NetworkManager.Singleton.IsClient) // make sure we are not running the server yet (and we are not the client)
{
    var type = NetworkObject.GetType();
    var fields = type.GetFields(System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic);
    foreach (var f in fields)
    {
        if (f.Name.Contains("IsSceneObject"))
        {
            f.SetValue(_obj, false);  // _obj is NetworkObject component
            break;
        }
    }
}

And then I simply spawn the NetworkObject manually when I click Host

Worked for me, probably gonna optimize it a bit more - cache that field somewhere and reuse it

[forest grotto]

if i have button to start the game it would call a function that first launches dedicated server and the server is ready move/connect all players in the lobby to the ip of the server? that should work

[sharp axle]

That would probably go through the matchmaker but yea I think that's doable

[fair escarp]

Hey guys i followed https://docs-multiplayer.unity3d.com/netcode/current/about/index.html. It spawns two guys but the cameras are always teh same between two clients. How do i fix this?

[sharp axle]

Yes, the server always has full permissions

[sharp axle]

There should only be one camera in the scene. If it's in your player prefab, then you need to disable or destroy that extra remote camera

[fair escarp]

But how do I give the players separate views then?

[sharp axle]

Do you need separate views on one client? Are you doing split screen?

[fair escarp]

No separate views on different clients. When I did a host and a client only one camera worked. I guess I need to try server and client?

It's a 3rd person shooter

[sharp axle]

just check for !IsLocalPlayer then disable the camera.

for 3rd person, I usually use Cinemachine. Leave the main camera in the scene and have a virtual cam on the player and set it to follow the local player

[frosty kelp]

Can a host not use server rpcs? My client can shoot the host but my host can't shoot the client

[tidal prawn]

Hi, I got this code for client and host playermovement (just some simple movement) the issue is the client moves way slower and is kind of janky any ideas how I fix this? ```public class Player : NetworkBehaviour
{
public NetworkVariable<Vector3> positionPlayer = new NetworkVariable<Vector3>();
private void Update()
{
if (IsOwner)
{
ClientInput();
}
}

private void ClientInput()
{
    Vector3 moveDir = new Vector3(0, 0, 0);
    if (Input.GetKey(KeyCode.Q)) moveDir.x = -1f;
    if (Input.GetKey(KeyCode.D)) moveDir.x = +1f;
    float moveSpeed = 3f;
    Vector3 position = transform.position;
    position += moveDir * (moveSpeed * Time.deltaTime);

    if (transform.position != position)
    {
        ClientMoveServerRpc(position);
    }
}

[ServerRpc]
void ClientMoveServerRpc(Vector3 position)
{
    transform.position = position;
    positionPlayer.Value = position;
}

}```

[austere yacht]

a server needs to use a client RPC if it wants to talk to a client

[sharp axle]

Host is a client and server so a ServerRPC should work

[austere yacht]

true, but it would be terrible design, direct method call would also work 😄

[frosty kelp]

So my host shoots a million bullets at a time, and I am getting a client that cannot change this network variable error. Except my code works for clients just not the host. I can't figure it out.

[sharp axle]

Weird. Clients shouldnt ever be running a serverRPC in any case. Make sure that script is actually a network behavior.

[frosty kelp]

Is there another way to handle hit registration? I checked it is a network behavior.

[sharp axle]

That way should work. But also you don't need the notify client rpc. Leave the health variable default server authoritative and just have the client sub to the playerhealth.OnValueChange()

[frosty kelp]

I fixed the issue, my network variable write permission needed to be set to server, not owner. I will change the health ui to change from OnValueChange() Thank you for your help.

[fallow adder]

So im trying out photon pun 2 and I wonder how can I sync ui panels for all players? I cant really find clear answer to that apart from rpc for something simple like text so I didnt try it + its not a room, its a lobby to join rooms from, I instantiate panel on canvas with room info through photonnetwork.Instantiate and I see it for a split second before scene is loaded only on player who created it

[austere yacht]

when doing multiplayer stuff, you're basically custom building most of those things with RPCs and SyncVars (if your framework has them)

if you're lucky your framework can sync transforms nicely and offers some help with animations

[fallow adder]

[tidal prawn]

Ive created a simple movement script but the client is laggy and way slower why is this?``` public NetworkVariable<Vector3> positionPlayer = new NetworkVariable<Vector3>();
private void Update()
{
if (IsOwner)
{
ClientInput();
}
}

private void ClientInput()
{
    Vector3 moveDir = new Vector3(0, 0, 0);
    if (Input.GetKey(KeyCode.Q)) moveDir.x = -1f;
    if (Input.GetKey(KeyCode.D)) moveDir.x = +1f;
    float moveSpeed = 3f;
    Vector3 position = transform.position;
    position += moveDir * (moveSpeed * Time.deltaTime);

    if (transform.position != position)
    {
        ClientMoveServerRpc(position);
        transform.position = position;
    }
}

[ServerRpc]
void ClientMoveServerRpc(Vector3 position)
{
    positionPlayer.Value = position;
}```

[tidal prawn]

isnt the clientnetworktransform unsafe

are there any examples on this?

[rapid plover]

first time doing multiplayer

[tidal prawn]

yeah new to this network thing thnx

[olive vessel]

Your class needs to inherit from MonoBehaviourPunCallbacks instead of MonoBehaviour

[rapid plover]

oh

[rapid plover]

thx

[sharp axle]

@vestal stag @tidal prawn I ran across this the other day. Seems like a pretty good start
https://www.youtube.com/watch?v=leL6MdkJEaE

[tidal prawn]

thnx Ill check it out

[forest grotto]

is it just me or are there just no tutorials or doc. on how to setup a server-client way for NGO (dedicated server that clients connect to ) If anyone has any forum post or tutorial on how to make it work plz hlep

I can get it to work but its only localy i need to build the game press a button to start a server then join it that all works but how do make it so other people that arent on my LAN connect to the server (tried to open a port and ip in my router put my PC ip and port 7777 and not working)

[sharp axle]

You would either use Multiplay(or some other service) to host your server, or you use the Relay Service to get around NAT.

[forest grotto]

So i can use Relay to connect clients to a standalone server?

I cant use P2P for my project

thats the problem

[sharp axle]

Sure you can have the server start a relay
Code Monkey just put up tutorial like yesterday.
https://www.youtube.com/watch?v=msPNJ2cxWfw

otherwise you're paying for server hosting.

[forest grotto]

Thx il try it

[sharp axle]

or asking your users to set up port forwarding on their routers

[forest grotto]

why do they have to do it??

its a small thing just a hobbie so if somebody wants to play il just start a server

[sharp axle]

in that case you'll need to set up port forwarding on your router

[forest grotto]

yeah i just put port 7777 and for ip i put my IPv4 from Ipconfig and my friend tried to join and nothing

I done port forwarding for Asseto Corsa and it worked

anyways il try the relay thing

[fallow adder]

Im so confused with this from photon fusion, does it mean even in host mode no players will have authority over the game even the person who is hosting the game? Who is the "referee" then Im just concerned about cheating if by some miracle my game sees the light of the day

[sharp axle]

Host is just a server that just happens to have a player controlling it. Server is one with no player and usually not even graphics.

[fallow adder]

yeah so that means host can say nah ive got 999hp?

[austere yacht]

you will not run a game sensitive to cheating in host mode, if you want to mitigate opportunitites for cheating you need to run a dedicated server, implement a server authoritative architecture, make client builds with stripped server code and verify all data you receive from clients

[fallow adder]

what you think is it worth building the game in host mode to test the waters of multiplayer then try swapping into server mode would there be lots to change

I imagine its just invisible "player" joining before anyone else and host it

[sharp axle]

Don't know about photon but if you keep that in mind it shouldn't be to much of a hassle.

Usually it comes down to changing checks with isHost to isServer.

[fallow adder]

cool

[ripe mesa]

in Fusion there would be not much change, u can use HasStateAuth (for server logic only) AND creating IsHeadless for batchmode build

[gritty olive]

I'm making a game, with Photon Pun, where you can push boxes, for example. I'm spawning them with InstantiateRoomObject, the problem is, when the not host pushes the box, it looks very weird, and the box isn't aligned properly. How can I fix?

[gritty olive]

maybe length?

[rapid plover]

worked here

[gritty olive]

but players is an array, which need .length, right?

have you tried length?

[rapid plover]

ill try

[rapid plover]

does not work

[gritty olive]

ok

[olive vessel]

It's .Length

[rapid plover]

like players.Length.Count()?

[olive vessel]

No

Players.Length

That is how you get the Length of an array

[rapid plover]

Wasn't It not like that before?

[olive vessel]

Do you think .length and .Length are the same?

[rapid plover]

worked before

[olive vessel]

I don't believe Array has a .Count() method

Either way if you want the count of elements an array has, it's .Length

If it's a List, it is .Count

[gritty olive]

I have a sceneobject, I want to sync between the clients. My problem is, that it's using Physics, so using Photon Transform View Classic doesn't work.

I ONLY want to sync the object if it's to far from the version, of the master client.

How?

Seems like Photon Rigidbody View could work

[rapid plover]

Weird... https://hatebin.com/itbftfmchs

[fallow adder]

https://hst.sh/yivolulodi.csharp Im controlling same avatar from both instances of the game in one of them input is even reversed somehow this is funny because thats what photon fusion introduction told me to do the only difference is I use rigidbody guy in youtube set his input in same way for fps shooter as well also I instantiate camera locally like you would in singleplayer game and Its seen in another player wtf is even this

[wispy arch]

So an RPC cannot be Async.

Can the Method being called from it be async?

example.

[austere yacht]

yes, but async void is a code smell

[wispy arch]

Why is that

[austere yacht]

because you will have no way to reference that thread and its state in a proper way and you'll not get proper exception handling

[wispy arch]

Understandable

[austere yacht]

you should always return Task

[wispy arch]

any Async would requrire a try catch too right

[austere yacht]

no

the exceptions bubble up

but you can use exceptions to detect whether an async method was cancelled

[wispy arch]

Right on. Thank you!

Hmm even after removing the aync It still doesnt call for the client. Not sure what im doing wrong

[austere yacht]

hard to tell from the bit of code you shared

is your client the same app?

ok

put in some debug logs and see if the OnHit gets called

this can have many reasons

its practially impossible to debug remotely

[hoary pivot]

Question regarding Netcode:
What would the value of 'NetworkManager.Singleton.ConnectedClients.Count'
be inside the OnNetworkSpawn method of the host's Player prefab?

[tidal prawn]

any reasons why a serverrpc wont execute? I just call the function in an if statement and it goes to the if statement but it doesnt run the rpc

[hoary pivot]

I just had that same problem

Does your script the RPC is running on extend NetworkBehaviour instead of Monobehaviour?

@tidal prawn

[tidal prawn]

NetworkBehaviour

[hoary pivot]

Damn

[tidal prawn]

its weird xD

[hoary pivot]

Tried requiredowner=false ?

[tidal prawn]

jups didnt do much

the thing that bothers me is that Ive put logs everywhere

and all of them are shown except for the rpc one

does the ServerRPC be spelled like that or can it be ServerRpc

cus I saw somewhere it had to have that in the name right?

also for some reason my host controls both of the players now

[hoary pivot]

I think Rpc is fine spelling

Sorry brother that is all the info I have on that, only learnt about Netcode in the last few days and still im not really getting how netcode is working

[tidal prawn]

same here documentation feels very limited been having a hard time xD

[hoary pivot]

Yeah ikr, feels outdated and thin haha

You might be able to help me with a problem:
I'm wanting to access: NetworkManager.Singleton.ConnectedClients.Count
From a client, but I'm not allowed to

[tidal prawn]

euh

[hoary pivot]

I've stored the value in a NetworkVariable on a few different scripts, but its getting to the point where most scripts need access to the value: doesn't feel right to have all these networkVars holding the same value

Is there maybe some way I can make the NetworkVariable into a singleton or something?

[tidal prawn]

cant u just store it in a single script? and just acces that?

[hoary pivot]

I could

But what if all scripts need access to the value at the beginning of the server? How do I make sure the script I choose to set/update the value does so before all the others need to access it?

[tidal prawn]

I cant think of a solution sorry, you could add an on value changed but even then it prob needs to be put on each of those scripts

maybe theres some sort of reload thing but I wouldnt know sorry

[hoary pivot]

No worries, thanks(: I'll prollly just chuck them on every script for now haha

GL with ur problem. Feel free to ask it again cause I've probably pushed it up now haha

[tidal prawn]

y2

[sharp axle]

Yea, that is Server only. Clients don't have access to other client info

[sharp axle]

The ServerRPC is not running on the host?

[tidal prawn]

its not running anywhere

but theres a lot more wrong on existing code its okay thnx anyway!

just gonna rewrite that part

[sharp axle]

Just to be clear ServerRPCs will not run on the client in any case. They get sent to the server/host and will run there only

[golden pivot]

I am having really weird issues with network transforms, for some reason the Network Behaviour Id does not match the Network Behaviour Id Cache. This results to the wrong thing getting updates, and I don't know how to fix this. Does anyone have a fix?https://gyazo.com/4fa28ca6065e634f72c81a374ba958e4

version on host

same script on client

Fixed it, one of the network behaviours was destroying itself when it shouldn't

[hoary pivot]

I'm after NetworkSpawnManager.SpawnedObjects

Any idea what I don't have access to it?

[mellow sapphire]

Hi, I'm using SandBoxie to test my coop VR game, however I cannot seem to create a license or even manually activate a license using SB. Anyone has a solution to this?

Nothing happens after I "activate" them, it still appears a message that I need a activated license

When I try the manual way, it appears a message saying that I cannot save the license.

I tried using Unity Hub 3.3.0 and 2.0.4

[hoary pivot]

Looks like NetworkSpawnManager is depreciated.
Thanks documentation. Using this instead:
NetworkManager.SpawnManager.SpawnedObjects

[sharp axle]

use NetworkManager.Singelton.SpawnManager.SpawnedObjects

[sharp axle]

I've never used that one. Does ParrelSync not work for you?

[mellow sapphire]

Never heard of it

What happens if I clone the editor and edit the original one? Does it change for both of them?

[sharp axle]

https://github.com/VeriorPies/ParrelSync

[sharp axle]

This does exactly that

[mellow sapphire]

Perfect! I will try it out

Many thanks Good Otaku!

[mellow sapphire]

It worked @sharp axle! Thanks again!

For those using VR, simply tick off the marked optiont to not run VR in the editor you don't want to run VR

[fallow adder]

Is anyone using/used photon fusion for their game? How did you learn how it works?

[normal estuary]

Hey guys, sorry for also posting here, but I can see my post ranking worse and worse on the forums. Perhaps here I'll be luckier, since the issue is probably very simple for someone with experience in networking, unlike myself.

[weak plinth]

whats the best netcode for an open world game with about 16-32 players in each server

[rapid plover]

So, I'm working on a Pun 2 multiplayer game, I would prefer a character controller over a rigidbody controller, but the character controller seems to not work (video below). the scripts by themselves are the only thing that's different in the controllers apart from the character controller and rigidbody components, so the only possible thing that could have gone wrong is in the script 2. I added the code links and the video below.

player manager https://hatebin.com/ccueoanqtb
character player controller (the bugged one) https://hatebin.com/llrehjbulm
rigidbody player controller (the one that works) https://hatebin.com/hgkgztvnbu

[sharp axle]

Changing Player color

[sharp axle]

All of them can handle something of that scale

[weak plinth]

which one would be best for hosting your own servers, and having two projects that are server, and client

@sharp axle

[austere yacht]

None, they all expect client and server to be the same app. If you split the projects you best also drop down to implementing custom netcode on top of a KCP transport (not worth it unless the clients aren’t unity apps)

[sharp axle]

I can't really say for the others. But it's doable in NGO but it's not recommended. I've done it but it's more trouble than it's worth to split the project

All the frameworks can be built as dedicated servers that can be hosted wherever

[weak plinth]

is it better to use your own socket implementation, or would you say i should just use ngo or photon

[sharp axle]

I wouldn't be confident enough to write my own socket layer. The Unity Transport is already too low level for me

[weak plinth]

what networking solution do most unity games use?

[sharp axle]

Photon I think is the most used. But it's also been around for the longest. NGO has only been out of beta for less than a year. Mirror is pretty popular too. Fishnet is pretty new as well but is gaining popularity

[wispy arch]

This may be way over my skill level. But is there any way to have Clients be on different Scenes than the Host/Server whathave you.
I mean I know its possible.
But how hard is it

[sharp axle]

In NGO, you would have to use additive scene loading. The server still has to have all scenes loaded in memory. A bunch of tiny scenes should be ok.

[wispy arch]

If that's the case, a Dedicated Server approach would be best than you think?

I am limiting to 4 players tho.

So if someone is hosting the max loaded Scenes would be 4 I suppose.

And this is a 2D game. So i would assume I don't need to go that route.

[austere yacht]

there is no way of knowing that. You can only guess by looking at how much the individual ones are talked about, but consider that all this info is heavily biased towards amateurs/hobbyists. Also games that actually release to commercial success may use custom or obscure ones that see way more traffic than any of the talked about frameworks.

[little sorrel]

I recently started using photon. I leaned from "quickstart" and other random tutorials. Also google helps alot. Photon takes a bit to understand stuff like Photon Views and nicknames but you should be able to grasp it with enough effort

[fallow adder]

Oh you are talking about photon pun which was easier to understand but it had shared authority I wanted server/host so swapped to fusion

And for fusion I found only their manual and one guy on youtube doing fps shooter with it thats all

[little sorrel]

lol

everyone wants an fps shoter

[sharp axle]

I didn't realize Fusion changed so much. Fusion has only been out slightly longer than NGO. Everything is too new and everyone is trying to figure it out as we go

[hoary pivot]

Oh thanks. Whats the difference with/without Singleton?

[sharp axle]

The singleton is the actual in game instance. Without it, it's a static class

[hoary pivot]

Netcode Question: What callback runs when a client connects to the server?
I've tried OnStartClient but that doesn't seem to exist

[austere yacht]

OnNetworkSpawn() runs for all NetworkBehaviours at network start and you differentiate client/server/host/local by checking IsServer, IsHost, IsClient or IsLocalPlayer

[hoary pivot]

Sorry I'm just learning the terminology.
Is NetworkStart = ServerStart?

Or will a network start occur for each connecting client?

[austere yacht]

its like Start() in a non-networked monobehaviour

it runs when the object that the component is on is spawned by the network manager

[hoary pivot]

Will it run for a connecting client on objects that are already spawned on the server?

[austere yacht]

yes

[hoary pivot]

Oh okay thank you!

[austere yacht]

that is the main purpose of having a netcode library (dealing with all these common sync/connect situations/questions and turn the answer to most of them to "yes, automatically under the hood")

[hoary pivot]

Thank you for explaining it well to a novice(:

[austere yacht]

but the key to understand is, that once players are connected, scenes are loaded and stuff is spawned, its all left up to you to make stuff sync

[hoary pivot]

Gotchya. I think I'm starting to get the hang of it now. Just struggling without some clear documentation haha

[sharp axle]

i found the docs to be pretty good here
https://docs-multiplayer.unity3d.com/netcode/current/about

[sharp axle]

also for clarity the actual connection callback that you can subscribe to is NetworkManager.Singleton.OnClientConnectedCallbac

[split hedge]

Hey can someone help me why did I get this error?

here's a piece of the code

[neat veldt]

I don't know photon but from the error it's clear you're instantiating before the player joins a room.

[hoary pivot]

Got any more?

[split hedge]

Yes

Wait I'll show you

[split hedge]

here is the manager script where i instantiate

[hoary pivot]

So you're calling Spawn before anyone has actually joined

If the object that the Manager class sits on is already in the scene before anyone joins, its Start method will run immediately when you load the game up, I believe

[split hedge]

Yeah, so how do i fix it?

[hoary pivot]

Idk fam that's a design choice.
You'll want to somehow wait until your server has started before calling Spawn

I used Photon for 2 seconds last week, so idk off the top of my head. I'll see if I can find what you're after

[split hedge]

using Photon.Pun;

namespace Com.makk87.FPSGame
{
    public class Launcher : MonoBehaviourPunCallbacks
    {

        public void Awake()
        {
            PhotonNetwork.AutomaticallySyncScene = true;
            Connect();
        }

        public override void OnConnectedToMaster()
        {
            Join();

            base.OnConnectedToMaster();
        }

        public override void OnJoinedRoom()
        {
            StartGame();

            base.OnJoinedRoom();
        }

        public override void OnJoinRandomFailed(short returnCode, string message)
        {
            Create();

            base.OnJoinRandomFailed(returnCode, message);
        }

        public void Connect ()
        {
            PhotonNetwork.GameVersion = "0.0.0";
            PhotonNetwork.ConnectUsingSettings();
        }

        public void Join()
        {
            PhotonNetwork.JoinRandomRoom();
        }

        public void Create()
        {
            PhotonNetwork.CreateRoom("");
        }

        public void StartGame()
        {
            if(PhotonNetwork.CurrentRoom.PlayerCount == 1)
            {
                PhotonNetwork.LoadLevel(1);
            }
        }

    }
}

Sure, here is the launcher script tho.

[latent cairn]

Can i ask about unity Multiplay and Matchmaker here?

[hoary pivot]

I'm not sure what this contains, but heres a guide walking through the basics of setting up a game with Photon. I imagine the answer to your question is in here somewhere:
https://doc.photonengine.com/en-us/pun/current/demos-and-tutorials/pun-basics-tutorial/intro

[split hedge]

I did follow a tutorial on youtube, but somehow it doesnt work well for me

[hoary pivot]

Put in a debug message where you believe the client should be connecting to/creating a room.
Put a debug message just before the instantiation happens. See which one is logged

[sharp axle]

you might get better help over on the official Photon discord

[fallow adder]

try instantiating your player in OnJoinedRoom and wrap it into if PhotonView.IsMine tho all of it looks confusing why u check if player count == 1?

[split hedge]

Im news to unity a bit, can you explain more?

[split hedge]

What should the debug message contain?

[split hedge]

There is not..

I can't get these child images to set active while on the network.

you can hear the sound effect that plays when it get activated but no actual activation occurs... I've done worked so hard to add networking to my game and got so much help along the way , but I'm ready to throw in the towel on this

Hello
I am having a problem with netcode for game objects.
For some reason I can't get my characters spine to transform correctly for the other users
The spine of the character has the script ClientNetworkTransform on it
I am a bit unsure what the issue is exactly, but it might have to do with the spine being deeply nested? Just a theory

https://i.imgur.com/iPKl3FL.gif

Showing the spine being rotated at the end of the gif ^

I do have multiple clientnetwork transforms on GamePlay player, kiddustsucker and spine

[fallow adder]

im so giga confused with photon fusion has anyone done anything w it like at all

Im just trying to instantiate camera locally

it shows up for everyone

its not network object

it messes up input as well

because of camera being instantiated

which is not network object

[fallow adder]

nvm noticed a callback Spawned() on NetworkBehaviour of player then with if Object.HasInputAuthority it finally worked definitely did not spend 2 hours on this

[uncut bluff]

hey guys how do you manage parenting network objects?

ah ok I think I can just go and find a transform to parent with a string of the name of the object

[weak plinth]

what do you guys think about riptide networking?

[jagged fulcrum]

Hi first of all, I'm developing a multiplayer game using Unity netcode for gameobjects and I'm havi

[wispy arch]

public override void OnNetworkSpawn()
    {
        if (_healthComponent == null) gameObject.GetComponent<Health>();
        
        InitializeHealth(_soDataStats.stats[Stat.Health]);
        
        _currentHealth.OnValueChanged += OnHealthChanged;
        _healthComponent.OnHit += OnHit;
        _healthComponent.OnDeath += OnDeath;
        _healthComponent.OnRevive += OnRevive;
    }

Does it matter who subscribes in this function?

Or should it be only the owner, or only the server. etc

For reference, This Script is put on all Units (players enemies)

It doesn't matter. The UI could totally hook into this for example

[limpid wadi]

im using Photon to make an online crossy road game, left is client right is host. I cant figure out why the logs on the left are acting up (each log is multiple blocks wide, client blocks are lagging), can anyone help plz

[uncut bluff]

hey guys sugestion, I unerdand that for example I should do a rpc call for shooting because the other clients do not know that the other is shooting something, but for example capturing an object by trigger enter like capturing a flag, should I do a rpc call for that as well?

[neat veldt]

If the other clients know it's happening I don't see why you would need an rpc.

[uncut bluff]

yeah just needed confirmation to make sure that I was not mising anything thnaks

[spring crane]

Issue there can be making sure the triggers actually do run consistently on all clients, which is pretty unlikely. Assuming you aren't running a special setup, it's likely a much better idea to always have one of the clients (or preferably, server) decide these and broadcast to others.

[uncut bluff]

ah ok this is reasonable, thanks, this is why I was having doubts

[hoary pivot]

Netcode question:

Inside of a ServerRPC, an object is first instantiated, then a variable on the object is changed, and then the object is Spawned on the network.

Is that variable change reflected on clients?

[sharp axle]

Only if it's a network variable, I believe. But do note that the OnValueChanged callback will not fire when it first spawns

[raven nimbus]

Is Unity Netcode for GameObjects supporting Hololens (UWP)? This is the platform support page (https://docs-multiplayer.unity3d.com/netcode/current/about/index.html), but is the point "XR platforms running on Windows, Android, and iOS operating systems" including Hololens?

[sharp axle]

I don't think there is a reason why it wouldn't

[pearl narwhal]

Hi everyone, sorry for the newbie question, but I am still learning

I want to use unity to make a virtual "lab" that clients can connect to, to walk around.

I need to have the level that I make in unity start on a server somewhere, and then have clients use the web browser to connect a first-person-controller into the game and then walk around

I have got unity working and compiling to WebGL and I can walk around my level in the browser, but I dont know how to architect a central server, where many users can connect

I just need the users to be able to walk around, nothing that fancy,

is there a framework or library or known way (or template I can purchase) that has this functionality? Any guidance would be greatly appreciated, I dont even know really what to google search (unity client / server levels? Unity MMORPG? ) whats the term I'm looking for?

You'll likely be using websockets if it's in the browser

Just wondering how i could go about having health for each player in networking for gameobjects. I have tried using networkvariables but they would only work for the host

[jovial karma]

When using NGO can you have network objects spawned in scene and load that scene with the network scene manager? Or do i have to instantiate all network objects after the scene is loaded?

[novel fog]

hello uh can anyone tell what this means?

[spring crane]

Looks like you are trying to join a room before you have joined a lobby. Look into how to use those callbacks if you haven't already

the player already joined the room

the player can create a room and join but cannot join an existing room

You'll want to look into dedicated server hosting. Unity game services has Multiplay. Netcode for Gameobject has websocket support in beta right now. There is a community developed websocket transport that you can use in the meantime
https://github.com/Unity-Technologies/multiplayer-community-contributions#transports

[split sonnet]

hi everyone, how can i check unstable or slow internet connection i unity??

i have used internet reachablity class but that just for checking if user has internet access or not, it cant check badwidth

[austere yacht]

Send a time stamp to the client along with a payload of a certain size (let’s say 100kb, can be garbage but must not be compressible) and have the client send it back in two stages, just the original time stamp and then together with the payload. The difference of the 3 time stamp values gives you an indication of their latency and bandwidth. Repeat at least 10 times or keep repeating for 10 seconds. You can improve the accuracy by sending packets of various sizes.

[split sonnet]

okay i want to know more about this, how can i achive that?

btw i'm not using unity multiplayer, i'm working with nakama

[austere yacht]

this is just based on how networking works, you can come up with all sorts of variations of this idea based on what you actually want to measure (also packet loss etc)

to make your own metrics you need detailed understanding of your transport and the usage you expect. A synthetic measurement often is not representative of real performance.

[split sonnet]

my problem here is that i'm creating a multiplayer game that uses socket, and ofcourse as you know lag will happen regardles of how you configure things, my game is turn based and needs user to a state to eachother to say my turn is over and it's your turn, and when the internet slows down players can't reach that state when their turn starts and the whole game will stuck in that postion

so in order for that to not happen i need a way to retry that state for users when the internet get back to natural

[spring crane]

Seems like some sort of reliability layer should deal with this in some fashion

Either by resending until success or disconnecting

[split sonnet]

this is an issue related to network jitter

[austere yacht]

Sounds like you are trying to reinvent what netcode libraries and existing protocols have already solved in 15 different ways

I suggest you read up on KCP (a widely used protocol/transport for reliable UDP) or use any existing implementation of a reliable networking protocol, http comes to mind

[split sonnet]

i deployed my game on AWS using nakama server and postgre database, when this happens i check the server log there is no errors accourding web requests bit this problem occurs with socket

[austere yacht]

You could also have a look at gRPC or read the docs of ZeroMQ which are excellent for learning about protocol development in general https://zeromq.org/

[split sonnet]

thank you so much for trying to help me.

is there a simple way to check badwith with unity???

[austere yacht]

If you use raw sockets (idk what nakama offers to help you) then you have a very long journey ahead of you. Nobody here can help with that. This is really arcane stuff.

[austere yacht]

No

[split sonnet]

no no, i'm not using raw socket, it's managed by them and just accesing from the api

[austere yacht]

You should not have issues like that when using a prefabricated network layer

If the issue is in the gameplay logic that needs to account for lagging/disconnects of players, this becomes a wholly different discussion

[split sonnet]

i'm living in an absolute hell right now, i've developed this game for a company and i finished everything by now even publihed it, i handled dissconection by checking for internet reachability, and now we are facing huge huge issues with bad internet connection

this is like a nightmare

[sharp axle]

There is not much you can do about a bad connection other than fail gracefully and attempt to reconnect the game

[split sonnet]

and this is what i'm trying to do, i want to check internet band width and jitter and send reties based on that

[austere yacht]

Typically you architect and develop multiplayer games with maximum still playable unreliability in mind. Anything too unplayable gets ejected/terminated.

[sharp axle]

You can't really test either unless you are already connected

[austere yacht]

Are you sure the jitter is the clients fault?

[sharp axle]

if you are using server hosting, then that service might have a way to test the quality of the connection before it connects to the server

[austere yacht]

Jitter is usually caused by a crappy server architecture/protocol

[split sonnet]

nakama is advanced in every way, you should read some about it, but i'm still very stuck why this happens.

[austere yacht]

Doesn’t mean you can’t build a crappy server on top of it

advanced is a really meaningless attribute

I see that nakama is even the most advanced

[split sonnet]

you are right, so now i really have to dig deep to see what i'm doing wrong

[sharp axle]

Not even just the server but the connection/bandwidth to the server host could also be garbage

[austere yacht]

seems to me nakama is for horizontal scaling of a game. It’s very different from the “first vertical then horizontal” scaling you do with ‘regular’ multiplayer

And it’s also a one size fits all thing, where other products like playfab or photon cloud offer only parts of the whole solution with a more open architecture

[split sonnet]

yes, there cloud base is heroic cloud

they don't allow horizontal scaling if you use other cloud providers like aws or oci

but here is how i configured things on my side if any of you understand these variables

[austere yacht]

those are irrelevant to your problems, they just define when a connection will drop

if you send too much stuff those settings won’t help you

[split sonnet]

these all depend of the amount of message you send and the size of each message

[austere yacht]

none of those values are anywhere near tolerable for regular play

these are “worst case, this is bad, get out of here values indicating a dropped connection, crashed server or data center on fire.

[split sonnet]

these are nakamas default

[austere yacht]

I’m not saying they are bad, I’m saying they have nothing to do with your problems of network jitter

Maybe the queue size does

[split sonnet]

yes i set the queue size based on experiece, there default is 16 but it did not work for me i kept getting errors from the server saying my queue size is full

[austere yacht]

How many requests does the server process per second and how many bytes does it read/write?

[split sonnet]

so based on the messages i send and how frequesnt i send them this was the best option for me

[austere yacht]

This indicates that your network doesn’t have the throughput you need

[split sonnet]

i've done a stress test and the server can handle 1000 requests per 1 second

[austere yacht]

the queue should be practically empty at all times

[austere yacht]

That’s not much

[split sonnet]

i'm using 2xlarge aws instance

[austere yacht]

sounds like you have a massive bottleneck somewhere

[split sonnet]

i tried to reduce we requests as much as possible on client side

[sharp axle]

I guess it would also depend on what region that server is located and where your users are

[austere yacht]

maybe your server code is just bad

Do you write to the Postgres DB a lot in those requests or call any other APIs that may be slow.

maybe the resources that the server depends on are congested without any way to recover from that

[split sonnet]

hmmm my requests are like this, first i login in and then i request to get the user account which i have some values saved in the database ( username , ID , Level, Win and wallet) and in my menu section i have something that detect how many players are online which is also server side code) and friends list

[austere yacht]

You do that for every request? Does the server have no state?

[split sonnet]

okay guys my game is in app store and google play store you can check it your self

it's called Meet 2 Play

okay i found this in the nakama documentation

[austere yacht]

if you query the user data from a db in each request your performance will be atrocious

[split sonnet]

nakama stongly suggests to not write querys your self they handle that themselves

[austere yacht]

This is an api you should call only once over the lifetime of a session

[split sonnet]

will this benefit me ??

[austere yacht]

I get a feeling that there is a design flaw in how you use the nakama backend

[rapid plover]

worked before I updated the postprocessing package

[sharp axle]

Sounds like your player is null. But that has nothing to do with post processing.

[olive vessel]

Not sure what that has to do with Player being null?

Somewhere you call SetUp and pass in a Player, that'd be more helpful to see

[olive vessel]

It has 2 references

[rapid plover]

in load balancing client

[sharp axle]

This one looks fine. It's being called somewhere else

[rapid plover]

same script, load balancing client

[sharp axle]

No you have Setup() being called somewhere else in your code

[rapid plover]

here

[sharp axle]

nope PlayerListItem.Setup()

[rapid plover]

@sharp axle it worked like 30 min ago, I didn't change the script or the prefab

[sharp axle]

I don't know what to tell you. One of those calls is passing a null player. maybe do a null check before call Instantiate()

[rapid plover]

ok

[rapid plover]

Decided to use the good ol' method, works when I restarted my pc 💀

first time do I see something like that but aight

[rapid plover]

I am using a character controller, is it possible to use something like character controller instead of collider[]?

[sharp axle]

What is it that you're trying to do? The Physics system only really deals in colliders.

[rapid plover]

Anything not to add a collider to the player unnecessarily without sacrificing data usage

[sharp axle]

I mean what problem are you trying to solve here? As far as I know, colliders don't use any network data. Maybe photon is different.

[rapid plover]

isTrigger will do it ig

I just didn't want a useless second physical engine in my character

[blazing lagoon]

so yea... I'm trying to make 2D multiplayer with procedural dungeon generating with tilesets and thinking how could I send the generated dungeon from host to the client and checked with just the floor tiles how many would I have to send so... Anybody think its feasible to transmit 11 131 x- and y-coordinates. YES I probably should be using some seed based generator but plz no I don't want to touch the generator part anymore.

[mental plover]

What if you just generate it on the host, and the clients will request the neighbour cells as they go?

Already got the info in one place, no need to duplicate it in this case

[rapid plover]

why does the billboard not work?

[sharp axle]

This isn't a networking issue
But I don't think you need rotate and look at

[rapid plover]

I want the UI to look at the camera for the name to be easier to see

[rapid plover]

and thats why I use the script in the first place

but I only have the host object

[sharp axle]

only other thing might be moving too often? And its filling up the buffer. I dunno

would that let me use my own networking solution, or would i have to buy into their servers?

[sharp axle]

Yea. It's network agnostic

And it's free for up to 5000 concurrent users

[wide ferry]

I have been directed here

so basically unity has deprecated the unity multiplayer tools

which seem very needed to allow clients to interact with network transforms

is there something I am missing, how are people making multiplayer games without the ability to allow clients to move game objects

[sharp axle]

What exactly are you referring to here. The Multiplayer Tools are for profiling and testing
https://docs-multiplayer.unity3d.com/tools/current/install-tools

[wide ferry]

yes

but they also include ClientNetworkTransform

which would allow clients to send over data for their transform instead of only the host

this is for netcode with gameobjects btw

[sharp axle]

Oh that just got moved

[wide ferry]

it did?

to where

[sharp axle]

https://docs-multiplayer.unity3d.com/netcode/current/components/networktransform#clientnetworktransform

It's also much simpler to implement now

[wide ferry]

ill see if this works

OH yes this works

thank you very much

In Photon, if i have a gun which is a child of the player, would i give the gun child its own PhotonView or just acess the parents?

[rapid plover]

Pun?

[thick valley]

yes

[rapid plover]

It will work ok without one

[thick valley]

But what if I need to check if you are the “owner” of the gun

[rapid plover]

Do using Photon.pun

And then just check if pv is mine

[thick valley]

But how would I access the parents photo View

[rapid plover]

Transform.parent.pv

[thick valley]

Ok thanks

So for every child of the “player” I should just use the parents?

Photon view

[rapid plover]

Why would you need to use it anyway

[thick valley]

Only shoot if you are the “owner” of the gun

[rapid plover]

Yeah if pv is mine should do

[thick valley]

with PV being the parents photon view?

hey, I have a question. If I want to store stats in a database and there are players playing from the whole world. I'd need Database-Server in EU, America etc. right? I cant just host like 1 server here in Germany because the Americans would have connection problems then right? Even if I just store stats in it?

Or is there a better way to do it?

And of course if I have like a Server in EU and in America, they would have to sync their data or does Steam has some kind of system?

[ripe mesa]

you would only need the main 1 datacenter (write datacenter)

the rest is read-only datacenter

[steep sparrow]

does steam api provide datacenters?

[ripe mesa]

nope

this is kinda wide question

simple database can be used from firebase

if you need strong database, there is amazon Aurora (SQL)

[steep sparrow]

I just want to store some info about players like the level, a players balance, and some more stats about them, probably just accessing and writing once before game and once after game

[ripe mesa]

is your game multiplayer?

[ripe mesa]

you can use Playfab or Lootlocker for BaaS (Backend as a Service)

[steep sparrow]

not at the beginning, maybe later but I'd use Steam newest system for Mulitplayer

[ripe mesa]

They let you implement easy system & let you not worry abt the infrastructure

[steep sparrow]

is it expensive?

[ripe mesa]

It's price is acceptable

Hi, i want to tiptoe into multiplayer. Did Netcode for gameobjects make stuff like fishnet or mirror obsolete? 🤔

[olive vessel]

No, it's just another networking solution

I suppose you could say it made UNet obsolete, as it replaces UNet as the official Unity solution

But UNet was deprecated ages ago

[whole slate]

i see... 🤔 Thanks for the reply. now i have to evaluate wich to choose i guess

[neat veldt]

Netcode is not supported on webgl

or atleast only partly
https://docs-multiplayer.unity3d.com/netcode/current/about/index.html

The problem is that the host/server cannot be on webgl

[stray moth]

Nope fishnet still better in my opinion

can you get issues if you give the parent a network object component and the child?

[tidal prawn]

With NGO, you will need to send a clientRPC to toggle those child objects

[restive roost]

is it possible to do skill based matchmaking with steamworks ?

[sharp axle]

a quick google search says so
https://partner.steamgames.com/documentation/skill_based_matchmaking

[restive roost]

i did google it and i saw this answer but i couldnt figure out what was the next step 😅

so i figured someone here must have tried it before and could tell me where to start exactly cuz i know how to use steam with lobbies and normal matchmaking

but with skilled based am just confused as to what am supposed to do

[olive vessel]

It does show how you can do it

You can store a stat for their "skill", and lobbies can have data which includes the "skill" levels of that lobby

[restive roost]

ill try it thx

its sounds simpler than i thought

[sharp axle]

The real trick is figuring out how to calculate "skill" sometimes a win/loss ratio just isn't enough

skill based matchmaking is always an approximation bounded by the ability of a system to measure an individual's contribution to group success

[sharp axle]

If your game is 1 v 1, ELO is fine.

[austere yacht]

depends if you actually want to matchmake skill or if you want to substitute performance for skill (in which case ELO works well), there are many skilled ways to play a game that don't equate to the same performance in winning a game or creating an exciting experience

[lyric thunder]

how would i network photonVR's cosmetics and colour changing?

[sharp axle]

What is photonVR? I would assume that is already networked through photon

[lyric thunder]

photon vr is photon but vr

im saying photon vr beause im assuming the vr player rigs are different from the two

[sharp axle]

In team games I agree with you 100%. In 1v1 however, if the most skilled player is not winning, then I would question the win conditions and consider that a design flaw.

[austere yacht]

i'm just saying that performance (winning) is not the same as skill. Its a distinction you'd make when thinking about design and what is important to you creatively, what type of gameplay you want to create. Skill is considerably more complex and multifaceted than "winning". The simplicity of winning is why ELO works as a performance comparison tool. If you reduce your game design to that (which is fine) then ELO is your thing. If you want to make an enjoyable game experience, it might very well be irrelevant... one player might just be excellent at being chased, creating a bunch of exciting situations for their hunter or vice versa, the hunter letting the other narrowly get away again and again... this cannot be captured by "winning".

assuming that the trading of these exciting moments happens because of equally matched performance (measured by ELO) is not plausible.

if anything, equally matched performance results in a stalemate (in games that include elements of luck, more excitement is possible, chess produces stalemates, matchplay golf produces excitement (for the players))

[dire axle]

If I run the server in my computer and use unity provided relay, will players be able to find my IP address?

[sharp axle]

If you give them the relay code or use the lobby system

[sharp axle]

You are not wrong. But I would say that is no longer skill based matchmaking at that point. I guess this is more of a #archived-game-design question of how you measure excitement.

[dire axle]

they can access my IP details if I give the relay code?

[sharp axle]

No exactly. They get the IP details of the relay server which forwards it to your server.

[dire axle]

ah, thanks for the info!

[ripe mesa]

finally someone who has brain

[tidal prawn]

just saw it now thnx

is there a difference between just calling gameobject.setActive or NetworkObject.gameobject.setActive

will the other one do it for all the clients too?

[hoary pivot]

Netcode question:
How do I get the player object of the client that is calling the script?
A: NetworkManager.Singleton.LocalClient.PlayerObject.gameObject

[ivory mango]

Hey can I share my code here?

I'm trying to create synced player names

I'm following this tutorial, https://www.youtube.com/watch?v=OGVDIu7qOaE&list=PLS6sInD7ThM2_N9a1kN2oM4zZ-U-NtT2E&index=8&ab_channel=DapperDino the code is not entirely same I had to make some changes

The individual player names are synced on the server side but on clients side it displays their default text

[sharp axle]

Syncing Player Names

[balmy nova]

I'm using netcode, and for some reason the two games aren't syncing. They connect properly but they don't move on the other screen

[ivory mango]

How are you syncing them?

[balmy nova]

When a player joins the object is created, but it’s as if they’re in separate instances

They both see two objects, but if you move an object in one window it doesn’t move in the other window

[sharp axle]

You need to have a Network Transform on them

[balmy nova]

On all objects?

[sharp axle]

the ones that need to sync

[balmy nova]

Alright

[dire axle]

When they say that Unity give free 3Gb of data per CCU (Relay server) is that 3Gb Egress Data?

and ($0.09 per GiB US + EU) is that extra GiB to each CCU or total GiB?

[balmy nova]

I'm not clear on how to script controls for an object. When I try, only the host controls work at all

[silent olive]

My idea was to only have clients on webgl but they cant even connect like that

[olive vessel]

A WebGL client should be able to connect to a Desktop Host/Server if you use the right Transport

[ripe mesa]

look for client-server topology works

[hoary pivot]

Netcode Question:
My player is not animating on the network.
When I select the player in the Hierarchy and look into the animator tab, the blue bar loads as if the animation is playing.
Player has an Animator, animation controller and clientNetworkAnimator

Any thoughts?

[urban hawk]

Hiya, I'm looking to make a card game like Hearthstone/Arena/Master Duel, what networking solution would you recommend? I've heard of Mirror, Netfish etc but which would you recommend?

[ripe mesa]

how much is your budget? what topology do you want (p2p/client-server)?

[balmy nova]

anyone know how to make cinemachine cameras work properly with netcode? Currently all players are stuck in the same camera.

[urban hawk]

I'd like to be able to test the game for free I guess, so having the option to run it local, but for the eventual published version whatever works best for having lots of players be able to play at the same time I guess, is that client server?

[ripe mesa]

yes client-server, splitted into two

client-hosted & dedicated server

client-hosted is not secure because 1 player owns 100% the game authority

dedicated is very secure & expensive & require extra work

[urban hawk]

Oh okay, well, what would you suggest to start with if I eventually down the line want the kind of functionality a hearthstone or MTG arena has? Can you start small and cheap/free and go for a more dedicated high performance server later when you have the money for it?

[ripe mesa]

there is answer for easy setup

look for pun or fusion share mode from photon

servers are managed by photon, but your game will be similiar to p2p

but easy to cheat aswell

[balmy nova]

I'm having a pretty serious problem with netcode, it won't register any input from clients at all. It can only see input from the server

[ripe mesa]

I've said this before

look for client-server topology understanding

[balmy nova]

I get that

[ripe mesa]

so your input doesnt get sent to the server?

[balmy nova]

It's just not responding

yes

[ripe mesa]

not very clear

[balmy nova]

if (Input.GetKey(KeyCode.E))
does nothing

on client*

it works fine on server

[ripe mesa]

uhh

you didnt get my message

hows the code flow?

[balmy nova]

not familiar with that term

[ripe mesa]

ok cool

[balmy nova]

any idea what might be wrong with it?

[ripe mesa]

show code bro

[balmy nova]

only thing I can think of is the networkobject is a parent of the object holding the script, rather than the object itself

the comments on that code are from the original source and probably outdated

[ripe mesa]

are you using NetworkTransform?

or ClientNetworkTransform?

[balmy nova]

mhm

[balmy nova]

that

[ripe mesa]

use ClientNetworkTransform

if you want your game: less secure, responsive, easy

NetworkTransform is owned by server, so only server can modify It

you really didnt get my message

look for client-server topology

[balmy nova]

ahh

okay, that makes sense

[ripe mesa]

the most logic & secure way in client-server is, Client sends input to Server, wait for latency (ex: 20ms), Server accepts input -> move the transform

[balmy nova]

I get that, just never crossed my mind that networktransform was server only
it's 1am

[ripe mesa]

everything in client-server is 100% State is managed by Server

so It should be secure

unless you are using ClientRPC everywhere

[balmy nova]

there's no client network transform component, is it a setting in the normal networktransform?

[ripe mesa]

It came from a sample

becareful using It

cheater can modify your game binary & fly, teleport to whenever they want

[balmy nova]

crap

any way to stop that

it's very likely something like that would happen in my game

[ripe mesa]

look for client-server topology

for the last time

[urban hawk]

Yeah that's probably significantly more of an issue for a tcg, what about more secure options?

[ripe mesa]

client-server, dedicated server

difficult to setup & expensive

[urban hawk]

What solutions are there that use that?

Also, what is it that makes it so difficult

[ripe mesa]

Mirror, Fishnet, NGO, Photon Fusion, Netick

you have to manage multi-regions, deployment, extra backend server

dont forget matchmaking

its just a very deep rabbit hole

[urban hawk]

Oh okay

Wasn't fusion p2p

[ripe mesa]

there is 2: fusion client-server & fusion shared (similiar to p2p)

[urban hawk]

Oh gotcha

Looks like Fusion scales with CCU

Which I learned a few minutes ago means concurrent connected users

Which client-server option would you say is the easiest?

[ripe mesa]

fusion for agile development

its API, QOL, optimization is top notch

also look for Netick, Its pretty similiar to Fusion but still lacks some QOL

[urban hawk]

I'll have a look at that, thank you

[frail gate]

Hi im new to netcode and im trying to make some sort of a multiplayer chess game, and im trying to change the sprite for the client player, and im using a server rpc and it changed on the server but not on the client. can someone please help?

[ripe mesa]

show code

[frail gate]

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

public class PlayerNetwork : NetworkBehaviour
{
    [SerializeField] Sprite playerClientSprite;
    GridManager gridManager;
    GameObject spawnTileHost;
    GameObject spawnTileClient;
    int tileSize;
    
    void Awake()
    {
        gridManager = FindObjectOfType<GridManager>();
        tileSize = gridManager.GetTileSize();
        spawnTileHost = gridManager.GetSpawnTileHost();
        spawnTileClient = gridManager.GetSpawnTileClient();
    }

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

        if(IsHost)
        {
            CenterCameraToGridHost();
            PositionPlayerHost();
            gameObject.tag = "PlayerHost";
        }
        else if(!IsHost)
        {
            CenterCameraToGridClient();
            PositionPlayerClient();
            RotateClientSprite();
            ChangeClientSpriteServerRpc();
            gameObject.tag = "PlayerClient";
        }
    }

    [ServerRpc]
    void ChangeClientSpriteServerRpc()
    {
        transform.GetComponent<SpriteRenderer>().sprite = playerClientSprite;
    }
}

should i use a network variable to store the sprite or something? im really confused eventhough ive watched so many videos regarding netcode

[ripe mesa]

this is good, for late joiner

so the late joiner still have the latest update

[frail gate]

but if i dont wanna use a network variable how do i make it work?

[frail gate]

so the client can see the same thing as the server

in the picture above

[ripe mesa]

both client & server must have the same playerClientSprite

did you change it on runtime? or no

[frail gate]

i put the prefab in the playerclientsprite in the serializefield before runtime

and when it run the code will run changeclientspriteserverrpc() to the computer that is the client

[ripe mesa]

but the sprite only changed in the server view?

[frail gate]

yea

[ripe mesa]

wait...

ServerRPC lets client to execute code in Server

ClientRPC lets Server to execute in client

so you want have a universal RPC

[frail gate]

how do i do that

i just need the client player to have a different sprite

thats all

[ripe mesa]

look for RPC thats callable for both & will execute for all

[frail gate]

isnt there only 2 types of rpc? server and client

[ripe mesa]

NGO only have those 2 lol

who can change the color?

everyone?

[frail gate]

umm yea..?

[ripe mesa]

do ServerRPC & set a id for that Sprite

change sprite color on networked variable changed

store various sprite with unique id as scriptableObject

[frail gate]

ok

so what network variable data type should i make

int?

[neat veldt]

byte should be enough

[ripe mesa]

byte is good for small changes & rare access, because it only take 1 byte in memory

[neat veldt]

Yeah and when you don't need numbers above 255

[urban hawk]

How hard is it to implement networking retroactively?

Asking for a card game specifically

Like once the core game is already done

[silent pine]

It depends how complex your card game is, for a card game it should be fairly simple since you're going to mostly manage the RPCs yourself and there's little work with client side predictions / reconciliation etc'

[austere yacht]

In most cases it boils down to reimplementing everything

even if you don't actually reimplement "everything" the effort is at least equal to it. If your game design is also incompatible with a direct conversion to networked multiplayer you are looking at making an entirely new game mode.

[urban hawk]

I looked at Fusion and I don't think I can do the price structure they have, but I've heard a lot of bad about mirror as well from googling

so I'm struggling to commit to a networking solution

[silent pine]

Why not netcode / NGO?

free 😄

is your card game lobby based? or host/client?

[urban hawk]

I looked up a review that said it was basically only for small local type of games

[silent pine]

Do you require the game to be secure? i.e. server authoritative everything, not allowing cheating etc'?

[urban hawk]

I don't think it's lobby based, like it'd use matchmaking instead

Idk how highly I'm prioritizing it, since it's an indie title and I don't have all the time in the world but cheating doesn't sound great either

Especially for a card game where it's not as obvious

[silent pine]

Regardless of which networking solution you choose, you'll need to re-do every player interaction.

Instead of 'Player does A' it'll be 'Player notifies server that he wants to do X, server verifies, notifies players that Player did X'
For some client prediction it'll be 'Player notifies server that he wants to do X, and does X locally, server verifies, if not valid notifies Player to roll back, notify other players that Player did X'

[urban hawk]

Yeah that sounds like a lot 😅

Would you recommend NGO if I'm aiming for a (hopefully) sizeable playerbase

[austere yacht]

the marketing of NGO is completely wrong, its neither high level nor only for small games

[austere yacht]

the size of your concurrent playerbase is almost entirely unrelated to the netcode library you use for realtime sync, you are going to spawn a separate server instance for every match, and up to 32 players per match you can practically do whatever without worrying about your data bandwidth or CPU performance, if you are making a card game you can run a lot of concurrent game servers processes per single virtual machine

any persistence/matchmaking/clan-management you'd have in your game would be handled by a separate server that is not implemented with unity, it would typically be some sort of HTTP based API. A client app would just be an interface to that API.

[silent pine]

What's the card game about?

[austere yacht]

if you need any kind of scale you need a robust system for spinning up and shutting down servers, playfab and unity game services (among others) can give you that

[urban hawk]

Oh okay, so I don't really need to worry about server capacity in that way then

[austere yacht]

you need to worry in the sense that bad implementation leads to fewer server-processes per VM and more VMs cost more money

but if you have a card game, chances are your server can be very efficient

you could then take another step and maybe implement the gameplay server without unity, opening up a lot of complications but also a large opportunity for optimization

[urban hawk]

Oh it's like YGO / Magic level of game, like complex interactions, 1v1 gameplay with resource management and so on

[silent pine]

Also consider that the frameworks for game networks have a lot of abilities that you don't care about - like continuous physics / transform syncing.

you could implement a card game 'server' just by having an endpoint that runs some code, for example an AWS Lambda

runs code / keeps state

[urban hawk]

I'm aiming for something easy to implement I think, I'm not sure at this point whether I'm looking to implement AAA multiplayer before I've gotten the development supported somehow

[austere yacht]

its not AAA just because you go down a custom path. often using a prefabricated solution is more complicated than it needs to be for your particular situation.

but using a generic solution is very nice for learning about all the details that you may overlook in a custom attempt

in any case, i'd pick NGO, its the most integrated with unity, its documentation isn't the greatest yet but you have community support, active devs participating in the support and a model that is very similar to old UNet and Mirror

you can use NGO completely free, if you use dedicated servers you can use any transport you like and are free to host your game anywhere you want

the other option i'd go for is Mirror

mind that none of these netcode solutions give you anything to help with implementing gameplay, there is nothing automatic about them, stuff doesn't sync because of magic. Its all hand made, which is a good thing.

You can take that customization all the way down to custom messaging/serialization on top of the transport layer, skipping any inefficiencies in the RPC/SyncVars you might find problematic

[urban hawk]

Sure, yeah I've seen tutorials using mirror, I just don't want to be writing the code twice over if I can help it

I'll take a look at NGO

[austere yacht]

if you pick mirror or NGO you will be fine, both are very capable

[silent pine]

Go for NGO 😄

[urban hawk]

Thanks you guys!

[stray moth]

Dont forget about fishnet its also pretty decent,been using it for a while noe

[olive vessel]

Believe me, nobody will ever forget about FishNet...

[stray moth]

Cant tell if u are serious or not XD

[olive vessel]

It's notorious

[stray moth]

Ah

Did fishnet do something bad that i am not aware off?

[balmy nova]

I’m having trouble getting a cinemachine camera to follow a net code player prefab.

[sharp axle]

You should be able to have the prefab find the camera OnNetworkSpawn() and then assign itself to the camera's Follow field

[austere yacht]

it (or its author) is caught up in a pissing contest with some other devs and seems to engage in weird self-marketing practices in all the wrong places that make the whole thing very smelly and untrustworthy, paired with exuberant claims of superiority that don't help gain any trust with a sceptical audience.

There is nothing obviously wrong with it and other stuff made by the author is indeed quite nice. As to its claims to suitability for production projects, everyone has to make up their own mind, as nobody can actually validate those without doing an actual project.

mind that most people who actually make and release commercial games at significant scale do not frequent this channel

[stray moth]

Ah gotcha

understandable

[azure ember]

Using fishnet networking, how would I make sure that I only affect the players client, instead of switching cameras, cause I am trying to make my own camera system instead of using the one that I found in order to use raycasting

because when I use it, both clients go to view the recently connected player

here is my code

if (canMove && playerCamera != null)
        {
            float mouseX = Input.GetAxisRaw("Mouse X") * mouseSensitivity * Time.deltaTime;
            float mouseY = Input.GetAxisRaw("Mouse Y") * mouseSensitivity * Time.deltaTime;
            playerBody.Rotate(Vector3.up * mouseX);
            yRotation += mouseX;
            xRotation -= mouseY;
            xRotation = Mathf.Clamp(xRotation, -90f, 90f);

            transform.rotation = Quaternion.Euler(xRotation, yRotation, 0);
            orientation.rotation = Quaternion.Euler(0, yRotation, 0);
            //rotationX += -Input.GetAxis("Mouse Y") * mouseSensitivity;
            //rotationX = Mathf.Clamp(rotationX, -lookXLimit, lookXLimit);
            //playerCamera.transform.localRotation = Quaternion.Euler(rotationX, 0, 0);
            //transform.rotation *= Quaternion.Euler(0, Input.GetAxis("Mouse X") * mouseSensitivity, 0);
            //transform.rotation *= Quaternion.Euler(Input.GetAxis("Mouse Y") * mouseSensitivity, 0, 0);
        }

and yes, I know its very messy

[austere yacht]

this is not a problem specific to any netcode library, you just have to differentiate between the local and remote players by some property that is exposed by the library, usually something like "isLocalPlayer" on the library's version of a NetworkObject or NetworkBehaviour and then use that differentiation to grab/toggle the relevant things that you want to be driven by the local client

[azure ember]

ahh, thanks

[sharp axle]

@azure ember You'll also want to make sure that you only have one camera in the scene.

[balmy nova]

Not working, the camera is changed client-side despite me using OnNetworkSpawn, IsClient, etc. is there something I have to do to write to it on client side only?

[sharp axle]

You only have one main camera, right? The virtual camera needs to be disabled on any remote players being spawned

[balmy nova]

No, each character has a camera

Also it’s a free look camera set to orbit the player

[frail gate]

can someone help me?
Im trying to deal damage from one player to another but using server rpc or client rpc does not replicate the new health from the damage dealt to the client can someone help pls im new to netcode

[sharp axle]

Thats your problem, Unity will use the last camera loaded.

[sharp axle]

If you are using NGO, then make the health a network variable and it will automatically replicate to all clients

[frail gate]

but if the health is a network variable wont modifying one player's health affect the other player's health..?

[sharp axle]

Each object has its own network variable.

[frail gate]

ok let me try first

it works but i dont really get the concept behind it.
what i understand is that a network variable will always have the same value across all game objects right..?

so lets say i have 2 players, they both have the same network variable health
if i deal damage to player1 and its health gets updated that means because its a network variable then player2's health should also get updated right..?

or am i getting it wrong

nvm its not working it says client is not allowed to write to this network variable

[sharp axle]

It's not across all objects. Just the same spawned object

[frail gate]

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

public class PlayerHealth : NetworkBehaviour
{
    NetworkVariable<int> health = new NetworkVariable<int>(100, NetworkVariableReadPermission.Everyone, NetworkVariableWritePermission.Owner);
    
    void Update()
    {
        if(!IsOwner) return;
        Debug.Log(OwnerClientId + " health: " + health.Value);
    }

    public int GetHealth()
    {
        return health.Value;
    }

    public void DealDamage(int damage)
    {
        health.Value -= damage;
    }
}

[sharp axle]

By default only the server can write to a network variable

[frail gate]

im calling DealDamage()
on another script in the same gameobject

and it says client cannot write to this network variable

[sharp axle]

Only the owner can there. So do an isOwner check before changing the value.

[frail gate]

oh alright wait

do i need to change DealDamage to a server/client rpc..?

its not giving me the error anymore but the damage still wont be dealt to the other player

this is how im calling it on the other scripot

else if(isMoving && chosenSkill == "Missile")
        {
            for(int i = 0; i<tiles.Length; i++)
            {
                if(tiles[i].isSelectedMissile)
                {
                    StartCoroutine(SpawnAndDespawn(i));
                    GameObject playerOnTile = CheckIfPlayerOnTile(i);

                    if(playerOnTile != null)
                    {
                        playerOnTile.GetComponent<PlayerHealth>().DealDamage(10);
                    }

                    tiles[i].isSelectedMissile = false;
                    isMoving = false;
                    ReturnTileColorToNormal();
                    chosenSkill = "";
                    break;
                }
            }
        }

[sharp axle]

Yea. Almost all of that is going to have to be redone to work over the network. But yea, in that case deal damage should be a server RPC. And the health network variable needs to be server authoritative instead of owner

[frail gate]

ok

it still doesnt work

idk what else to do i just need to deal damage to the other player

and vice versa

[sharp axle]

I take it this was a single player game?

[frail gate]

umm no but im really new to netcode so idk how to start developing in multiplayer

and a lot of the concepts were really overwhelming

but i just need to finish this one thing

just this dealing damage thing

[balmy nova]

Then is it possible to make a camera be client side only?

[sharp axle]

Check for !isLocalPlayer then disable it

[balmy nova]

What do you mean disable?

[sharp axle]

Yea. It's a lot to wrap your head around. You have to keep in mind what is local and what it remote. ServerRPCs send data from a client to the server to run. ClientRPCs are the opposite.

[sharp axle]

Disable the camera on the players that are not the local player

[frail gate]

so there is no other way to solve the problem other than rebuilding the entire project..?

[balmy nova]

using Unity.Netcode;

public class PlayerStart : NetworkBehaviour {
    public override void OnNetworkSpawn() {
        base.OnNetworkSpawn();
        if (!IsLocalPlayer)
        {
            gameObject.SetActive(false);
        }
    }
}

I attached that to the camera

nothing happens

[wet compass]

in netcode, is there a way to call something once the server starts other than onnetworkspawn? is it safe to do it right after NetworkManager.Singleton.StartServer() or is that process not necessarily end on the same frame?

[stray moth]

I just use IsOwner in fishnet for my cameras and disable it if its not mine and enable if it is

[austere yacht]

You generally wouldn’t call those yourself , they get called automatically when the object and network are ready for you to use (similar to Start() in regular MonoBehaviour), anything else you need to happen once when networking begins needs to be triggered from there.

[surreal lily]

does netcode for gameobject have an auto discovery feature for users on the same wifi(PC/Android)?
I want to discover the server and edit the Connection Data's Address at runtime.

[sharp axle]

there is one here. no idea if it still works with 1.2 or not
https://github.com/Unity-Technologies/multiplayer-community-contributions/tree/main/com.community.netcode.extensions/Runtime/NetworkDiscovery

[surreal lily]

I tried it on earlier versions, but found no results using it,
hardly any info was given on it as well.

[sharp axle]

The easiest way is to just use the Relay and Lobby Service

[surreal lily]

would that solve the issue for the lan connection?

my app is more automated server/client approach,
I want the client to boot up and get the active server's address without the user having to go through settings/inputs,
for now I either read through a file that stores the IP or sync them through PlayFab, which kind of feels weird.

[sharp axle]

are you hosting the servers on Playfab?

[surreal lily]

just sharing the local IP, i find this approach bad, but fairly automated if set up right.

[sharp axle]

yea thats very bad

either use a hosting service like Playfab or Unity Mulitplay or use the Relay service for self hosting

[surreal lily]

would the relay service help?
the IP isn't static.

[sharp axle]

the server/host would start a new relay whenever it starts

if you need a persistent server connection, then a dedicated server hosting solution is your only real choice there

[surreal lily]

the operation itself is very simple, that's why this whole things is just overly complicated for hardly any reason.
the server acts as a starter/stopper for a 360 video between multiple VR devices. (so they are all synced up at start)

not sure relay would work as you would need to supply a join code

[sharp axle]

Nothing about networking is ever simple.
But yea Unity might be overkill for your application. A nodejs server will likely be as much as you need.

That said the Relay and Lobby system would work. The server/host starts a relay and a lobby. And the clients can just quickjoin the first lobby it finds automatically.

[surreal lily]

nah, it would need to be compatible with VR.

it's still quite a heavy project on VR side

[austere yacht]

sounds like you need a tiny little custom system/protocol that you can build quickly on top of a reliable transport if all this runs in a private network and you don't need to worry about scale, i'd pick something that encapsulates the idea of a push message (raw UDP can do that if you have a very controlled environment)

for simplicity i'd just make this a .NET server and not introduce a whole new tech stack if your project isn't yet steeped in web tech for no reason

[surreal lily]

Different approaches on some android phones failed, this worked.

[austere yacht]

do you know why they failed?

[surreal lily]

Not really, the error was vague.

[austere yacht]

you can always use HTTP/1.1 as fallback that "always works" if you don't need realtime performance

[wet compass]

with netcode, my client id is not being reset after disconnecting a client. it just keeps incrementing. is this expected behaviour? or am I missing out something to make it so that if no one is connected and someone joins they'll always be clientid 1

[austere yacht]

every connection gets a new, session-unique ID

[wet compass]

ok good to know thanks. so as long as the server isnt reset that number will just keep going up infinitely?

this confuses me though :

The clientId generated by Netcode for GameObjects (Netcode) cannot be used, because it generates when a player connects and is disposed of when they disconnect. That ID may then be assigned to a different player if they connect to the server after the first one disconnected.

from https://docs-multiplayer.unity3d.com/netcode/current/advanced-topics/session-management/index.html @ linking data to players

[olive vessel]

That would suggest they are reused by new clients

[wet compass]

So far I haven't been able to get it to reuse a clientid though, i'll have to do further testing but so far seems to act like Anikki says. Maybe it only start reusing clientid's after reaching a threshold?

[austere yacht]

it means they "may" be reused -> you cannot make any assumptions about how they are generated, reset or persist

essentially if you want persistent IDs to identify a player reconnecting you need to DIY that system yourself, usually via the data object a client can send with their connect request (used for something like an auth-token) or barring that, some sort of other Authentication mechanism the player sends once connected.

[sharp axle]

Unity Authentication works really well for that. it guarantees users will always have the same player id

[austere yacht]

is unity authentication tied to NGO in some way?

[olive vessel]

Nope, works standalone

[austere yacht]

how does it guarantee the player/connection ID in NGO?

[olive vessel]

I don't think it does, I think they meant that it would give you a player ID which you could rely on

Then do what you said by passing it in with connection approval

[austere yacht]

ah... kinda obvious that a player would be uniquely identifiable by an authentication service

[olive vessel]

You'd hope

[frail gate]

Hi guys im new to netcode for gameobjects, and i was wondering how could i host from any computer? becauase in here i need to set the address to the computer's ip but if i host from another computer then they have a different ip

[frail gate]

start as a host for my game*

[sharp axle]

You would need to use a Relay Service. either Unity's or someone else's. The Lobby service will let you search for existing games

[opaque ember]

Does anyone know how I can add like an in-game cosmetic with RPCs in photon? If anyone could help, that would be great!

like an in-game cosmetic through the network player

[robust cypress]

just have an RPC that spawns x hat on x player, then call said rpc

[sharp axle]

If it's like DLC, you could use addressables to download the new content.

[mighty whale]

Any solid documentation on DGS for NGO?

[sharp axle]

They literally just put this up yesterday
https://docs-multiplayer.unity3d.com/netcode/current/learn/porting-to-dgs/index.html

[mighty whale]

hmm, so would this make sense for a server authoritative city builder sim

Its what I immediately associate to, but I've been pretty deep in the weeds recently

[sharp axle]

Sure, any type of game can work with a dedicated server. Really just depends on how much you worry about cheating and what your budget is.

[shell nest]

How hard is p2p to implement?

[haughty heart]

Hard

[fallow wharf]

Is there an easy way to make a HTTP request utilising the new Awaitable in 2023.1?

[sharp axle]

If you need player hosted servers you can use the relay service. It's a reasonable alternative to p2p

[shell nest]

It's free, right?

I'm kind of intermediate.

[sharp axle]

There is a free tier. You will likely never go beyond it during development

[shell nest]

What does the paid tier have to offer that the free one doesn't?

Is the Relay service hard to use?

[sharp axle]

It's the first 50 concurrent users are free
https://unity.com/solutions/gaming-services/pricing

[shell nest]

Would that limit be higher with implementation from scratch?

[sharp axle]

What do you mean?

[shell nest]

If I were to implement P2P myself.

[sharp axle]

Then that's on you. But that's a nightmare to implement.

[shell nest]

But would it?

Aren't there any free plugins with a higher CCU?

[sharp axle]

If you do yourself there would be no costs as there is no service you are using

[shell nest]

I mean it shouldn't cost anything since it's the hosts' computers are running the servers.

So why is the CCU limit for Unity's relay service 50?

[sharp axle]

Relay servers cost money to run

Epics relay service is free to use I believe

Steam I think also has a relay service

[shell nest]

Are there any free plugins that have pre-implemented P2P?

[sharp axle]

Nope

At least not that I've found

[shell nest]

So to get access to Steam's P2P, you have to pay $100?

[sharp axle]

Pretty sure that's the case

But you're paying that to be on steam anyways

[shell nest]

I just wanna create a multiplayer game where you host a server with an IP and a port, and then you join lobbies that way too.

[sharp axle]

You don't want you players giving out IP addresses all willy nilly

[olive vessel]

You could allow players to make dedicated servers

[shell nest]

Yes, that's what I want.

[olive vessel]

People do it constantly for Minecraft

[shell nest]

on their computers.

yeah I was gonna say that.

[olive vessel]

If you use a relay, they don't need to port forward. If you don't they do need to port forward

[shell nest]

port forwarding is?

[olive vessel]

Opening a port in their router's firewall

To allow external connections

They could also host a dedicated server with a company online to avoid that

[sharp axle]

It's also a support nightmare

[shell nest]

and what's a port in a router's firewall?

[olive vessel]

25565 is an example of a port

[shell nest]

That's what I want. You've probably already guessed that.

[olive vessel]

There is a free relay from Epic if you want P2P connections with ease

Mirror has an Epic transport

[shell nest]

Yeah, evilotaku said that.

but mustn't I use Unreal then?

[olive vessel]

No

Mirror is a networking solution for Unity

[shell nest]

Noble Whale?

[olive vessel]

What?

[shell nest]

nothing

a p2p plugin.

but it costs $80 lol.

Could you send a link?

[olive vessel]

Not really, I'm pushing for time before work

Mirror is well known though

[shell nest]

ok

[olive vessel]

Anyways, good luck

[shell nest]

thanks

@sharp axle Do you have the link to Epic's mirror page?

[sharp axle]

I haven't used either of these but here was the first Google search result
https://github.com/FakeByte/EpicOnlineTransport

[shell nest]

"FakeByte"

What?

Are there tutorials for it?

Thanks by the way.

[sharp axle]

No clue. It's a custom transport

Mirror has their own discord that would probably help you out better

[frank crag]

hey I'm currently trying to make a basic multiplayer fps game with netcode. I have 3 cubes in my world and I've made a script, which lets the host pick up cubes, carry the cubes around in front of them and drop the cubes. When I try to do this as a client, I can't pick up the cubes.

more details currently coming...

Components on one of my cubes (besides of transform and mesh renderer)

Components on my player (besides transform, client network transform)

this is my pickup objects script

this is my objects grabbable script

if you need more information tell me!

I hope somebody can help me!

[sharp axle]

The cubes have owner authority. You will need to ChangeOwnership() of the cubes to the client that is picking them up

[frank crag]

Thank you, How exactly can I do that?

Or can I change the ownership, so that everyone can pick it up?

[sharp axle]

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

You can leave it server authoritative and then send an ServerRPC to have the player grab the cube. It might be a bit laggy that way though

[limber holly]

hello, I just create a multiplayer scene with netcode and I don't really find a guide for hosting my game and start trying it

[austere yacht]

You can use multiple build or editor instances to test locally. Helped by https://github.com/VeriorPies/ParrelSync for hosting you can use clouds like unity game services, playfab or your own machines. You can find documentation and examples for all of these (except DIY) but straight up tutorials will be less effective.

[zealous thicket]

Hi i wanna ask, currently i'm using photon Pun 2 to implementing Recovery connection with ReconnectAndJoin() with CleanupCacheOnLeave = false and it's work properly. But when player really want to leave the game, object doesn't leave or destroying itself.

I've done the manual way with PhotonNetwork.Destroy(playerDisconnect) but it doesn't work and object still alive, in other player

[opaque ember]

can anyone tell me why this code is not networked?

[frank crag]

i'm currently trying to make my game be accessible from my external ip, i'm using unity 2022.2.1f1 and netcode version 1.1.0

I have one input field and one button and if i press it, I run this code

however, I'm getting this error, when I try to join with my external ip. (I opened the port 5963 in my firewall and forwarded it on my router.)

If you need more detail tell me

Thank you

[vernal pagoda]

Hey, I am working using Netcode for GameObjects. I currently have a player that is setup hierarchal as such. WHen I spawn it in, its unhappy and states "Spawning NetworkObjects wit nested NetworkObjects is only supported for scene objects", this is fine, I can change my setup. My question is, my Player, TankTurret and TankBody all have network objects.

My question is should I create a class on the parent such as PlayerNetworkManager.cs, and then my TankTurret and TankBody get references to that, so that when they move or rotate, I can call IsOwner on them? Or what is the best course of action here?

[stray moth]

Not sure if this will help since i am using a diff networking solution but i run all my network code on the player empty that i spawn in then put a network transform on it to sync every child on it below

[opaque ember]

can someone help me with this please

[opaque ember]

hello?

[normal estuary]

Without getting into the nitty gritty, it's not networked party because it's a MonoBehaviour, and nothing about it is networked. I recommend watching CodeMonkey's multiplayer tutorials to get started

[opaque ember]

monobehaviourpuncallbacks?

[normal estuary]

I think it makes sense to have multiple scripts on the root player empty object, with references to each object using the Instance-based infrastructure

[opaque ember]

this?

[normal estuary]

yeah, start off with that

[opaque ember]

...

ok...

I use photon

not netcode

[normal estuary]

Oh, I see, then I actually don't know the answer to your question. Didn't notice, sorry

[opaque ember]

oh

[normal estuary]

I saw there is no Unity NGO method for NetworkManager.Singleton.StopClient().

When I want a player that is not the host to leave the game, how do I stop the client and destroy the network manager? How do y'all do it?

Oh, just found a juicy Shutdown() method. I'll use this along with Destroying the empty network manager once in a non-networked state for extra cleanup.

[sharp axle]

You'll get better help from the official Photon discord

[sour sparrow]

hey i am having "Unable to complete SSL connection" error when trying to get time from the website: https://worldtimeapi.org/api/ip

i found this class on the internet to validate every certificate:

public class ForceAcceptAll : CertificateHandler { protected override bool ValidateCertificate(byte[] certificateData) { Debug.LogWarning("Validating certificate"); return true; } }

and im using it like this:

`UnityWebRequest webRequest = UnityWebRequest.Get(API_URL);
var cert = new ForceAcceptAll();
webRequest.certificateHandler = cert;

    Debug.Log("getting real datetime...");

    yield return webRequest.SendWebRequest();`

but i am not getting "Validating certificate" message in the console so it looks like unity isnt even using the overrided function to validate it

how can i get the time from this website with no problems?

i am kind of a beginner when it comes to this stuff

[dapper raven]

Does anyone use mirror and steamworks? I have an error im having trouble fixing.

[lapis valley]

Hey, OOTL, is Mirror still the best networking solution? or has unity come out with their own

reposted from another channel

[ripe mesa]

Hello, does anyone knows how good UE netcode compared to unity multiplayer framework?

[daring sable]

Unity just game out with their own called netcode for game objects, but I've personally been using fishnet

[lapis valley]

I had a project i started a bit ago using mirror, is it ok to keep using it or do you think fishnet / netcode is better/more secure, etc

Im used to mirror and all of the netcode is written with it but ig im willing to switch if it’s significantly better

[daring sable]

Mirror is ok, fishnet is statistically better than both and workflow is similar to mirror, so I'd give it a shot as well. And idk much about NGO :p

[ripe mesa]

fusion is the best

[lusty glade]

fusion is meh, the manual is worse than pun, you need to download an example and build your game around that, or else, you wont even be able to create your own room

[austere yacht]

UE has an architecture that revolves around FPS multiplayer, unity is more generic. All the common libraries for unity can create highly performant multiplayer games, you just don’t get any of the prebuilt features and guidance toward a proper architecture you get from UE. Fusion is the closest thing to a ‘batteries included’ competitive multiplayer library for unity.

the netcode library you pick will not be the limiting factor of your multiplayer aspirations

[ripe mesa]

the manual may be worse, because It involves many setup n stuff, but It is the best in the market rn

[ripe mesa]

this could be true, but still depends if your game is for casual or competitive edge

[austere yacht]

You need to be careful with blanket statements like this. Fusion is a terrible solution if your game requires a different architecture

stuff like NGO is lower level than fusion and therefore more generic/less opinionated

with fishnet you also either buy into its way of doing the advanced features or you get zero benefits from picking it

Overall, ‘advanced’ usually means prebuilt tools optimized for doing one thing well in a narrow space.

[ripe mesa]

Great Opinion @austere yacht 👍

[ripe mesa]

have you used UE netcode before?

[lusty glade]

I agree, many 'advanced' tools are way too specific, ue for example, is geared for character based multiplayer, do a racing or physics based multiplayer and you'll have to do more workarounds or make your own multiplayer handlers

|| ☝️ speaking of my own experience with ue mp||

[austere yacht]

I’m sure UE multiplayer is good, it drives Fortnite, that’s an amazing benchmark. But that’s also what it’s made for and idk how it behaves in practice since I’ve personally never used UE at scale

[lusty glade]

ue multiplayer is really good indeed, the interpolation, prediction & reconciliation works out of the box (for character)

[austere yacht]

In any case these concerns are way way beyond the scope of any project discussed here. Most people here will never need what any of the libraries offer

[austere yacht]

How else would it work 🙃. It’s either built around it or not.

[ripe mesa]

is Lag Compensation exist in UE?

[lusty glade]

ah right, I forgot why I am here 😅
I'm using fusion
I'm still figuring out why my code doesnt work on client
it does work on host

    {
        gameObject.SetActive(false);
        Debug.Log("Spawning Player");//Called
        networkRunner.Spawn<NetworkCharacterControllerPrototype>(player);
        Debug.Log("Player Spawned");//Not called
    }

[austere yacht]

that’s what prediction and rollback is

[lusty glade]

I mean, there's no error, and it's not a coroutine to wait for

[ripe mesa]

bro... spawn only works on host
