Quick Question, Why am i not able to add the On Client Side Network Transform from the Netcode for Gameobjects using Git URL

[sharp axle]

If you are using NGO2 then you no longer need that one. There is a drop-down variable for authority type on the Network Transform.

The webinars should all be listed in #📢┃announcements

[ocean wadi]

I had a question regarding Netcode's .Spawn method. I was wondering if .Spawn recreates a copy of the object it is used on or the object's prefab? An example of why I need to know would be a dash special effect that leaves afterimages of the player. The prefab's sprite renderer starts off null, but is dynamically set to the player's current sprite. If I were to spawn the object, dynamically set the afterimage sprite, then call .Spawn, would the client side afterimage's sprite renderer be null or would it be the same sprite saved in the object?

[tame slate]

It would be null. It replicates on clients based on the prefab.

[sharp axle]

You would need to set the sprite in that new objects OnNetworkSpawn()

[ocean wadi]

If I was using an object pooling system and the method SpawnFromPool. Would I want to call .Spawn in SpawnFromPool or whatever code is calling SpawnFromPool? A problem I thought of was that if we call .Spawn in SpawnFromPool, but we need to change certain values of the spawned object after spawning, we wouldn't be able to use OnNetworkSpawn right?

[sharp axle]

If you are using Network Object Pooling then you can use NetworkObject.Spawn() as normal. OnNetworkSpawn() still gets spawned

[vivid zodiac]

Oh alright, thank you so much!

[vivid zodiac]

I assume it would be the anticipated network transform?

[sharp axle]

No, just the regular Network Transform.

[vivid zodiac]

I dont seem to have any drop-down variable for the Network Transform for Client only

Only got :

In Local Space
Interpolate
Slerp Position
Use Quaternion Synchroni
Use Half Float Precision

[sharp axle]

What version are you on?

[vivid zodiac]

2022.3.46f1

[sharp axle]

oh this is only in NGO 2.0+ for Unity 6

[vivid zodiac]

Oh shoot

that explains it

but then i wouldn't have problems with installing the Client Side Network Transform tho?

[sharp axle]

I don't know if NGO 1.11 or 1.12 has it though

[tame slate]

@vivid zodiac it's a really simple script, you can just create it yourself.

using Unity.Netcode.Components;
using UnityEngine;

namespace Unity.Multiplayer.Samples.Utilities.ClientAuthority
{
    /// <summary>
    /// Used for syncing a transform with client side changes. This includes host. Pure server as owner isn't supported by this. Please use NetworkTransform
    /// for transforms that'll always be owned by the server.
    /// </summary>
    [DisallowMultipleComponent]
    public class ClientNetworkTransform : NetworkTransform
    {
        /// <summary>
        /// Used to determine who can write to this transform. Owner client only.
        /// This imposes state to the server. This is putting trust on your clients. Make sure no security-sensitive features use this transform.
        /// </summary>
        protected override bool OnIsServerAuthoritative()
        {
            return false;
        }
    }
}

[vivid zodiac]

I'll take a look, thank you :))

[sharp axle]

its also here in the docs. super simple to just copy

[vivid zodiac]

That's literally just the whole script?

[tame slate]

Yeah.

[vivid zodiac]

I expected it to be atleast 100 lines

But thanks very much guys!

[covert gull]

Anyone here familiar with steamworks and can explain to me the difference between a CallResult and Callback? I understand how delegates and events work in regular C#. I don't understand the difference between these two types

[normal cypress]

is there any other samples for the ReadDelta and WriteDelta of the custom NetworkVariable? I hope they can just include it in the docs instead of just saying // Do nothing for this example.

[fluid walrus]

you can send an RPC with a NetworkObjectReference

[tame rampart]

how should I send an rpc to a specific client? I looked at the docs and there are examples using ClientRpc but apparently its deprecated

[tame rampart]

ah okay it looks like RpcTarget.Single((ulong)clientId, RpcTargetUse.Temp) something like this

I don't know what RpcTargetUse really is though

the docs aren't very helpful

[fluid walrus]

it is documented, but not in the most obvious place

https://docs.unity3d.com/Packages/com.unity.netcode.gameobjects@1.8/api/Unity.Netcode.RpcTarget.html

[sharp axle]

Its used to help with garbage collection. You would use persistent if you have a group you are always sending to like Teammates

[tame rampart]

when you say "always" do you mean like constantly?

[sharp axle]

Not necessarily. Its just for like caching the group so you don't recreate it every time you call the RPC

[tame rampart]

your example uses clientRpcParams, which I was under the impression is only able to be passed into a ClientRpc, which is deprecated now

like this

[plucky bramble]

Which lib is this?

oh nvm

[tame slate]

Legacy - not deprecated.

[tame rampart]

sorry yes, legacy

[tame rampart]

it's just netcode for gameobjects

I figured out how to do what I want (i think) so dont need to worry about me

[tame rampart]

https://docs.unity3d.com/2020.1/Documentation/Manual/UNetAuthority.html

I tried googling how to make a gameobject be client authoritative, and this old out-of-date documentation page is what showed up

does anybody know the current way I should do this?

[sharp axle]

Here are the docs for ClientNetworkTransform. But if you are using the latest version of NGO2 then you can set the authority directly in the Network Transform

[tame rampart]

isn't this just for position?

well, the transform

[sharp axle]

yes. For Network Variables, you can set the write permissions to owner

[tame rampart]

so instead of a gameobject being client authority in general, I would need to make network variables in my networkbehavior script and work off of those?

[sharp axle]

yes. you can mix permissions on the same object if you want

[tame rampart]

is there a way to get the owning client id from a player gameobject?

or should I cache the client id at the start of runtime

[tame slate]

You can get it from any NetworkObject

Caching is never a bad idea however

[copper pumice]

Hey,
I'm getting an issue with multiplayer playmode, but not sure if it's auth related or multiplayer play mode related.
I'm using Unity6 (6000.0.26f1) and multiplayer services 1.0.2
Running platform profile (Default Windows)
And when I activate Player2 I have a logic that initializes unity services then signs in anonymously
(I initialize unity services using default ctor without init options)
When I try it out in the main editor it's fine, but on the 2nd editor (Player002) it throws an error exactly when I try to sign in anonymously
Saying
Unity.Services.Authentication.AuthenticationException: invalid environment name provided ---> Unity.Services.Authentication.WebRequestException: {"detail":"invalid environment name provided","details":[],"status":400,"title":"INVALID_PARAMETERS"}

Am I asking this in the right place?

NOTE:
I also get the same error in default editor when I switch to "built profiles" but when choosing the default profiles everything is fine.

[sharp axle]

I believe you need to switch authentication profiles when signing in anonymously on the same machine. Not why it's giving an environment name error though. Make sure services settings have the correct environment name.

[tame rampart]

if I call Despawn on a gameobject (server authority), does that mean Update() will stop being called for it?

[copper pumice]

In the editor I'm choosing the Environment from the Project Settings to be "dev"
It works on my main editor, but it throws the env error on the Player002 clone-editor

[copper pumice]

I would think so, as it would destroy this gameobject's instance in the network.

Oh wait, you said Despawn not destroy

[tame rampart]

I mean like does it happen immediately - is there a guarantee that the next tick Update() won't be called for a networkobject that I called despawn on last tick

[copper pumice]

Hmm good question,
Maybe worth doing a test in your client and server Update method
Keep firing logs and also fire a log when it's destroyed/despawned
You'd be able to see if a log in Update gets fired after despawn

[sharp axle]

Despawn(false) will keep the object around on the server. The default is Despawn(true) which will destroy the network object.

There is also a DeferDespawn() that will delay it by a certain number of ticks

[tame rampart]

thanks, makes sense

[tame rampart]

One more thing - on a network behaviour script, who is allowed to modify variables? I mean ones that aren’t explicitly declared NetworkVariables

And is the prefab for a player that is specified in the network manager a special case or the same as any other network behaviour script

far as I can tell it's server authority for these

in which case, is this only working because I have a NetworkTransform component with client auth mode?

[sharp axle]

Default write permissions is Server

[sharp axle]

That is correct

[tame rampart]

I have a NetworkObject that starts in the scene and I want to cache a reference to one of it's components in my player's NetworkBehaviour script.

I think this works? tested and no crashes or unexpected behavior

at a high level I want items (like dropped stuff in minecraft) be able to interact with the correct inventory of a player thats nearby

[sharp axle]

Change Start() to OnNetworkSpawn() and it will be good

[tame rampart]

What could go wrong with using start

[sharp axle]

Start() gets called before the object spawns. So clients will get an error when the RPC gets called

also IsOwner is not properly set there either

[tame rampart]

thanks

one last thing - I feel like I don't super understand how it works when there's a host

it's a client that is also the server

meaning - if I write in my player script code that modifies variables (without a server rpc), it'll actually make the changes, but only in the host instance? other client instances will also try to run the code locally but it won't actually change variables?

[fluid walrus]

from a NGO perspective that's basically it, it's a player that counts as both for the purposes of ownership and RPCs, the rest of the logic is kind of up to you to implement

a lot of the time you want to be checking IsOwner in Update etc so clients only update their own objects and the host doens't try to update other clients' objects

[sharp axle]

Normally, you would check if IsHost/IsServer/IsOwner before making any changes to Network Variables

[tame rampart]

yeah - I mean for like regular variables (in a networkbehaviour)

I feel like i didnt explain what i meant very well

[sharp axle]

regular variables are always local and will never get replicated to other clients/the server

[tame rampart]

lets say i have a networkbehaviour script on a networkobject and it has a variable public int x = 0, and then inside Update() I do something like x = 5;

dang im confusing myself

but essentially for clients the modification will be ignored by the server right?

because it's server write perms only

i'd have to do rpc server call from client to request the server modify x, or make x a NetworkVariable<int>

[sharp axle]

x is not a network variable there. all clients and the server would be able to change their local x variable independently

[tame rampart]

makes sense - and for the host, it only has one copy of x between its client and server?

[sharp axle]

Yea. the host is a single entity. It just runs as a server and client at the same time.

[tame rampart]

I see now.. in this code I'm just changing the host's local variables. Other clients don't actually have updated local versions, which I imagine will lead to unexpected behaviors (if im not careful)

[sharp axle]

Just keep in mind that there are only 3 ways to send data in NGO. Network Variables, RPCs, and Custom Messages

[tame rampart]

would it be better to have a NetworkVariable that holds a reference somehow?

I know it's not possible to do NetworkVariable<MyCustomComponent>

is it allowed to do NetworkVariable<NetworkObjectReference>

[sharp axle]

sure there is also NetworkBehaviourReference

[tame rampart]

oh thats awesome, that's probably the way i want to do it

[tame rampart]

I tried to refactor but I'm running into this problem

I can't any examples in the documents where they use a NetworkObjectReference or NetworkBehaviourReference as the type for a NetworkVariable

[sharp axle]

Is your InventoryManager a Network Behavior on a Network Object?

[tame rampart]

i think so 💀

[sharp axle]

Could still be a timing issue. try using OnNetworkPostSpawn() to make sure all objects have spawned

[tame rampart]

it's still complaining

it has to do with FindFirstObjectByType<InventoryManager>()? that's the line that is causing the exception

[fringe imp]

if i have interpolate turned on on networktransform should rigidbody component interpolate be off?

[sharp axle]

That shouldn't matter as long as the InventoryManager object has been spawned. You could that it's .IsSpawned is true before sending it in the RPC.

[sharp axle]

I don't think it matters either way.

[tame rampart]

ah you're right, it's not spawned yet

I guess it makes sense that networkobjects in the scene are also waiting to be spawned when I start host

how do I delay trying to set it until the object is spawned?

I am using the OnNetworkPostSpawn() function too

[tame rampart]

okay, I figured out a solution. not sure if its best practices but whatever

I basically check if the inventory is spawned yet. if it's not, then subscribe to an action delegate from inventory script that gets invoked when its networkobject is spawned

if it is already spawned, then just add it

for some reason, the host seems to always spawn the player first, and a client spawns the inventory manager first

not sure how unity works!

[white meadow]

there is any tutorial how to use unity3d 6 multiplayer center? Some examples how start with that (not just sample gameobject and scenes cuz only that i found), I focus on server hosted method :#

[sharp axle]

The Quickstart Sample scenes are why you use the Multiplayer Center. You can use the widgets separately if you want them in your own scene

[vivid zodiac]

Is there any method like "OnSceneChange" for the NGO so when the scene changes i can get my custom network manager to check the name of that scene and if it matches just do what has to be done, i could very well put it in Update but it's not worth checking the scene name every frame

[sharp axle]

https://docs-multiplayer.unity3d.com/netcode/current/basics/scenemanagement/scene-events/

[vivid zodiac]

Thank you

[silent trellis]

does netcode for entities support adding component at runtime? I read the documents are it seems like it, but I am not sure if I understand it correctly since adding component at runtime sounds like a feature that too important to be ignored

[blissful jay]

none of the networking solutions for unity support that

[sharp axle]

Technically you can make it work. You probably shouldn't though. Structural changes in dots will tank performance. Components added at runtime won't be synced so you'll have to manually update them with RPCs

The folks on #1062393052863414313 would have more insight on this

[normal bluff]

    public void SpawnUnitServerRpc(ServerRpcParams rpcParams = default)
    {
        // Instantiate and spawn the unit at random position
        Vector3 spawnPosition = new Vector3(Random.Range(-5f, 5f), 0, Random.Range(-5f, 5f)); 
        GameObject unit = Instantiate(unitPrefab, spawnPosition, Quaternion.identity);
        var instantiatedUnit = unit.GetComponent<NetworkObject>();
        instantiatedUnit.SpawnWithOwnership(OwnerClientId);

        // Add unit ID to GameManager's NetworkList
        GameManager.instance.AddUnitServerRpc(instantiatedUnit.NetworkObjectId);
    }

Hello. I am having a little difficulty working on the logic for something I want to do. Above is the code I have but I don't think it does what I want.

I want to look at the unitPrefab on the PLAYER and instantiate that prefab. The instantiated unit should have all of the customization, abilities and choices that the player chose before the match started. I understand i will need to instantiate (or call an index#) for each of those customizations. What I dont get is, if the SERVER is calling this RPC, isnt the thing being spawned just the default prefab without the player's choices on it?

[sharp axle]

That is correct. You would need to send those customizations to the server in the RPC parameters. Or you could have those as Network Variables on the default prefab and let the client update them after they spawn

[normal bluff]

If i go the NetworkVariable route, how would I, for instance, instantiate a hat on the unit?

[sharp axle]

Depends on how many you have. They can all be on the prefab and just disabled. Or you could instantiate them locally on each when the network variable is updated. If they are network objects for some reason, they will have to be spawned separately then reparented to the player

[normal bluff]

So the eaier way is to make the gear/clothes just be there to begin with it looks like. This is incredibly helpful thank you.

[magic yarrow]

Can someone help me to figure it out what am i doing wrong, when i`m Loading scene my host have an error that he has 2 audiolisteners, also client is controlling my host

[tame slate]

The audio listeners is probably from having two cameras active and the client controlling the host means you're not making the correct checks on player input

[empty night]

Can someone tell me why my host moves just fine but my client has slow jittery movement?

[tame slate]

You’re just sending raw positional data back and forth across the network, which is subject to latency and jitter. I would recommend using the NetworkTransform component

[empty night]

I fixed it , forgot to remove my question

I changed authority mode on the player prefabs network transform from server to owner.

Now host and client move properly

[sharp axle]

If you are using Network Transform then be sure to remove those RPCs.

[empty night]

Remove the server RPC's?

[sharp axle]

The network transform itself is already syncing position and rotation. Your RPCs there are redundant and a waste of bandwidth

[empty night]

oh yeah I forgot about that

I took a year off c# and jumped into python , trying to re-review and get back into networking altogether

[mossy wing]

How do I fix "Internal build system error. read the full binlog without getting a BuildFinishedMessage, while the backend process is still running"?

[fluid walrus]

in my experience it's usually it's just a unity hiccup or antivirus or something interfering with the build, and reimporting a script or making a code change will make it go away

[mossy bluff]

hi guys im having trouble setting permissions on a NetworkVariable, does anyone have an example, im trying to sync a vector3

reverted to my old code that works but im trying to sync 2 mouse pointers only one of them works

[winter peak]

its any way to access network prefabs in ngo?

not spawned but registered ones

[winter peak]

or itself someone has some any good solution for spawning for example Tree thru static methods like some system soo I dont need to access like list of all networked prefabs but just do Like SpawnableObject.Spawn(ObjectType.Tree) which will return NetworkObject

I think anyway I need to create own scriptable object for this

[mossy bluff]

does a networktransform really od all the work without needing rpc?

been trying to sync to mouse pointers but spent along time with no success lol

one works the other just randomly jumps around

[sharp axle]

You can access the network prefab list. NetworkManager.NetworkConfig.Prefabs.Prefabs[]

[sharp axle]

Yes, make it owner authority and have it follow the mouse position of the local client. You spawn one mouse object for each player

[mossy bluff]

thanks!, would be awesome but i cant get it to work

does it work with a child being the network transform, and its a rect transform

[silent trellis]

Has anyone tried Photon Quantum before? I heard that it is also ECS, and can write code just like a local game.Without cost consideration, would you guys recommend using DOTS+Netcode for entities, or using Photon Quantum?

For an autochess-like game

[mossy bluff]

seems like dots would be overkill

[sharp axle]

The child would need to have a network transform. The parent needs to be a spawned network object

[mossy bluff]

yeh i think my problem was i was tryin to make a cross hair which needs a canvas

[sharp axle]

If you game will already be using Dots, then I would recommend NFE. Otherwise I would stick with a gameobject based solution

[mossy bluff]

i assumed netcode would be quite easy

which it seems so, just missing something

[sharp axle]

Networking is never easy

[mossy bluff]

yeh

im a network programmer lol

barely even connects have to keep restarting unity

[sharp axle]

But that said a 2d network object on a canvas will work

[mossy bluff]

yeh almost had it earlier but one was jumping around

may be unity bug

unity6*

oh seems to work after restarting!

so unreliable tho, nearly always wont connect

[silent trellis]

thanks man.

How many CCU does it support for each CPU core (assuming using the Unity Multiplay Hosting)? Supposed I am using netcode for entities, and a autochess-like game, where all entities in the match will be ghost, including bullets,etc.

[mossy bluff]

yeh i have to restart unity every single time to get one connect lol

works perfectly if i do that though 😄

[sharp axle]

I'm not too familiar with auto chess, but there is no hard limit. Most realtime games cap out at around 100 or so players. Turn based games can have much higher player counts.

[sharp axle]

What errors are you getting?

[mossy bluff]

i dont see any

[sharp axle]

Increase the log level in the Network Manager

[mossy bluff]

suddenly seems more reliable

ah good thinking

hmm just says [Netcode] [Host-Side] Transport connection established with pending Client-1.

but i never see this when it fails-> [Netcode] [Server-Side] Pending Client-1 connection approved!

[sharp axle]

Are you using Connection Approval? Are there any messages on the client side?

[amber spire]

What does this error mean?

I have a pizza level (picrel 2) with the following hierarchy (picrel 3) with a network object on a pizza prefab. Am I doing something wrong?

[blissful jay]

Photon Quantum is production-ready

Netcode For Entities is not

Photon Quantum is infinitely better than anything Unity has ever made

[amber spire]

I figured out what the problem is. The thing is I simply want to enable gravity when a player stand on an object, however I don't know how to solve it simply.

Seems, like I would need to spawn all these prefabs to make it work

[mossy bluff]

anyone know a quick and easy way to implement a lobby

[winter peak]

its possible to access ip address while doing approval check? also its any main reason why "Reason" in response is as string? unity ngo

[mossy bluff]

anyoneseen this error KeyNotFoundException: Specified number of players (2) not found in Remote Config player options.

trying the unity serverless lobby demo

[sharp axle]

https://docs.unity.com/ugs/manual/lobby/manual/unity-lobby-service

[sharp axle]

You can not. unless you send it through Connection Data for some reason. "Reason" is a string because you can enter whatever reason you want

[mossy bluff]

damn why does nothing ever work without a fight with unity

looks like a very cool sample though, does A LOT of the hardwork

[sharp axle]

that sample is a bit over engineered for my tastes.
If you are using Unity 6, look into the new Multiplayer Services and Widgets packages. Using Sessions does a lot of the integrations for you

[mossy bluff]

cheers, will check it out!

ah id not deployed the remote config, theres tons of new stuff in unity6 i have never seen

[winter peak]

huh

[mossy wing]

Even though I already asked a similar question, how do I use unity as a webhost?

[sharp axle]

You don't? You would probably run a webserver along side the unity executable on whatever server machine you have access to

[vivid zodiac]

Hi! I have a question, im wondering for why this scene event isn't working? I just wanna say that i am pretty new to networking but gotta start somewhere, so if there is some very easy and obvious answer to why it isn't working then sorry for bothering lol, but been trying to debug it for the whole day, even asked chat gpt and still no answers.

void Start() 
{
    if (NetworkManager.Singleton != null && NetworkManager.Singleton.SceneManager != null)
    {
        NetworkManager.Singleton.SceneManager.OnSceneEvent += OnSceneChange;
    }
}

private void OnDisable()
{
    if (NetworkManager.Singleton != null)
    {
        NetworkManager.Singleton.SceneManager.OnSceneEvent -= OnSceneChange;
    }
}

private void OnSceneChange(SceneEvent sceneEvent)
{

    Debug.Log("Working1");

    if (NetworkManager.Singleton != null && NetworkManager.Singleton.SceneManager != null) 
    {
        if (sceneEvent.Scene.name == RoundSceneName)
        {
            Debug.Log("Working2");
        }
    }
}

[sharp axle]

Is this script in the Round Scene or in the scene before it? SceneManager might be Null is Start() since the network as not started then

[ocean wadi]

Hi so I am currently changing my single player game to multiplayer. I am testing the features by running a playtest and build on the same machine. This means that I should pretty much have 0 latency between the host and the client, but I was wondering is it normal to have very slight latency when doing this? When performing a high speed action such as dashing, I noticed there is a very slight delay between the client and the host. Additionally, there is also a very slight delay when spawning objects and stuff. Is a very slight delay normal when testing on the same machine or is there something wrong?

[sharp axle]

If you are testing on Relay there will still be the usual ping delay. But even connecting directly on the same machine there will be a delay of at least a frame or two for RPCs and 1 Tick for network variable updates.

Hi, is anyone aware if it's possible to create custom inherited RpcAttributes?
I'd like to have defined attributes for common usage patterns, eg [FXRpc] instead of [Rpc(SendTo.Everyone, Delivery = RpcDelivery.Unreliable)] - but doing eg public class FXRpcAttribute : RpcAttribute, doesn't seem to trigger the codegen to transform the method into an rpc call
Am I overlooking something while defining my attributes here, or is this not achievable with the way NfGO is structured?
edit: dug into the codegen source and yeah, looks like i'd have to modify com.unity.netcode.gameobjects//networkbehaviourilpp.cs, which isn't really ideal :\

[amber spire]

Is it possible to change ConnectionApprovalCallback while NetworkManager is already running a server/host?

[normal bluff]

I used to have something in my unity that let me fake four different instances of my game so i can test multiplayer. Once i pressed play the game would run in Unity and it would bring up 3 other windows with the game running different players and i could make on the host. I am desperately trying to find out what that was again. Anyone know?

For anyone wondering, I found it. Its not a github download like it was before when i first used it in experimental mode. In Unity 6 its caleld Multiplayer Play Mode

https://docs.unity3d.com/Packages/com.unity.multiplayer.playmode@1.3/manual/index.html

[vivid zodiac]

Its in the network manager, like just a custom network manager if you get what i mean

[mossy bluff]

still cant get 2 players showing up on each others screen using netcode

think i had nit then i moved to try make a lobby with their example and i dont know how again..

also the one that does work is so delayed even on localhost, id hate ot see it across a real network

theyve made the whole thing into a nightmare, might go back to pun

[winter peak]

Attempted to write without first calling TryBeginWrite()

soo I need to calculate size by using if(!writer.TryBeginWrite(sizeof(float) + sizeof(bool) + sizeof(i))) { throw new OverflowException("Not enough space in the buffer"); } yes?

[fluid walrus]

yeah, or the use Write[x]Safe methods

[winter peak]

Safe method checks size every write yes?

and writevalue is more performant while doing just trybeginwrite on start?

also what about reading?

if someone can tell if its correct way of reading/writing stuff

or I should just use serializevalue thing while its not that complex

[fluid walrus]

yeah, it's the same in both directions, you either need to tell the reader how many bytes you expect to read or use the safe methods

it's only a small bounds check per read/write to use the safe methods, so checking the bounds ahead of time is more valuable the more frequently you're doing those operations

[winter peak]

while using BufferSerializer.SerializeValue(ref something) I need to also check size?

[fluid walrus]

iirc those call the safe methods

[winter peak]

hmm accessing NetworkList in awake method and list is null hmm

like networkmanager in lists is null idk why

[winter peak]

its any proper way to make networklists? I mean I do have public NetworkList<byte> _syncEffectsIntensity = new NetworkList<byte>(); but while doing _syncEffectsIntensity.Add in Awake its throwing nullrefs
if (!CanClientWrite(m_NetworkManager.LocalClientId))

[tame slate]

They have to be initialized in Awake, IIRC.

and you should ideally be adding to them after the network starts, not before.

[winter peak]

soo if its player object then it should be fine in awake?

[tame slate]

I believe Awake always fires before network init on an object, so no

[winter peak]

public override void OnNetworkSpawn() ?

[tame slate]

Yeah, that's where it would be best to do it

[winter peak]

NetworkObject.Spawn()

[tame slate]

Initialize in Awake

Add to in or after OnNetworkSpawn

[winter peak]

finally no error spam in console aa thanks

now one action after spawning player object results of unity editor just closing

just attached debugger into unity uh oh

[fringe imp]

How common is it if instead of spawning bullets, bullets are local, and if you hit someone you just inform client you hit them?

[tame slate]

This will make the person shooting the bullet very happy as it will always look like they hit the person they shot, but this will almost always result in the person who got shot being pissed because it didn't look like they got shot

[fringe imp]

aha ok cool, i would imagine this is the way to go for me as its more of arcade style game and is client auth.

Im running into some issues in my current setup where i hit them but doesnt show any damage on their end. ( only sometimes )

i spawn projectile, assign force, and projectile detects hits. youre throwing cards at eachother. Not sure if i should take different approach

anyways thx for the help

[spring marsh]

hi, im trying to make a lobby broser with facepunch.steamworks, i have this function that creates a lobby with Gameid unique to the game name set with SetData:

    {
        Debug.Log("host");
        NetworkManager.Singleton.OnClientConnectedCallback += OnClientConnectedCallback;
        NetworkManager.Singleton.OnClientDisconnectCallback += OnClientDisconnectCallback;
        NetworkManager.Singleton.OnServerStarted += OnServerStarted;

        NetworkManager.Singleton.StartHost();

        CurrentLobby = await SteamMatchmaking.CreateLobbyAsync((int)maxMembers);
        CurrentLobby.Value.SetData("game_id", "TOFLOATBOAT");
        CurrentLobby.Value.SetJoinable(true);
        CurrentLobby.Value.SetPublic();    
    } ```
then i have this next function that searches for that lobby using the same gameid:
```     public async Task<bool> RefreshLobbies(int maxResults = 5)
    {
        try
        {
            Lobbies.Clear();
        var findLobbiesQuery = new LobbyQuery();
        findLobbiesQuery.WithMaxResults(maxResults);
        findLobbiesQuery.WithKeyValue("game_id", "TOFLOATBOAT");
        var lobbies = await Task.Run(() => findLobbiesQuery.RequestAsync());
    

        
        if (lobbies != null)
        {
            for (int i = 0; i < lobbies.Length; i++)
                Lobbies.Add(lobbies[i]);
        }

        return true;
        }
        catch (System.Exception ex)
        {
            Debug.Log("Error fetching lobbies", this);
            Debug.LogException(ex, this);
            return false;
        }
    } ```

My steam app ID is set to 480, so when I remove the specific game ID filter in the refresh lobbies function I can see other developers lobbies, but when I do it with the game ID filter I can’t find anything even when hosting the same game on another computer, is this because I need to get my own steam app ID first?

Any help is appreciated!

[sharp axle]

You would do this for slower moving projectiles like rockets or grenades. For bullets it's normal to raycast from the player on the server to determine a hit.

[sharp axle]

I don't use Steam lobbies, but my understanding is that it needs a valid Steam game ID.

[normal bluff]

I am getting an error trying to check lobby or player data. I know it takes a few seconds before the data exists but even with a null check, when i poll the lobby the data updates throw null. And it happens every poll no matter how long i wait. Any idea why?

Its happening in multiple palces but the most common is (currentLobby.Data.TryGetValue("MaxSize", out var maxSizeData))

[tame slate]

Hard to say just from looking at the code, but I always discourage the practice of manually polling lobbies for updates to their data. Lobby Events are the way to go.

[normal bluff]

Do you have a good place to start with Lobby events? This lobbydata is really causing my headaches

Oh i think i see it. They're like normal events you can subscribe to. Thanks

[tame slate]

https://docs.unity.com/ugs/en-us/manual/mps-sdk/manual

There's also this which helps to combine Lobby/Relay/NGO in to one easy to use package if that works with your setup.

[normal bluff]

Ive currently set it up like this. Something seems off though.

I dont see event documentation in that site but i may ahve missed it.

[tame slate]

All of your UI changes and whatever else uses the data has to be updated within those event listeners

[normal bluff]

await LobbyService.Instance.SubscribeToLobbyEventsAsync(currentLobby.Id, callbacks);

I cant tell if this is correct. I had to wing it. do you know?

[tame slate]

Yeah, that's correct

https://docs.unity3d.com/Packages/com.unity.services.lobby@1.2/api/index.html

documentation can be found here

[normal bluff]

Wonderful thank you!

[sharp axle]

You can find more code examples here

[covert gull]

For an indie game that has co-op multiplayer, is it better to provide a lobby list for players to choose from when looking for public games to join, or should I implement automatic matchmaking where you set some filters and automatically get put into the closest matching lobby?

I'm using steamworks. Currently I have a lobby list, but I'm starting to think automatic matchmaking might be better?

[tame slate]

Usually automatic for public lobbies and then the option to make a private lobby that's joinable via code/invite

[covert gull]

Thanks, that's what I was thinking. Need to work on implementing that

[normal bluff]

Oh yes! Thank you! Examples awlays help

[sharp axle]

If you aren't too far along, give the Multiplayer SDK a shot. It really does make things a whole lot easier. There is a migration guide if you decide to switch.

[normal bluff]

Im currently using it... I think. I had an issue where there were two relay instances and i had to uninstall one. I guess relay is built into the multiplayer now?

[tame slate]

it's built in to that package

along with Lobby

that migration guide tells you what you need to remove

[normal bluff]

Yea i didnt realize that at first. So i had rhem all installed LOL. all my references were bugging out

[sharp axle]

Oh, if you are then you don't need to mess with lobbies directly at all. Sessions handles all that for you

[normal bluff]

omg....

What are sessions?

This lobby thing is driving me NUTS

[sharp axle]

https://docs.unity.com/ugs/en-us/manual/mps-sdk/manual/create-session

[tame slate]

an encapsulation of a Lobby/Relay/NGO instance/group

[normal bluff]

oh man. I'll gladly start my front end of my game over and do this instead. Lobbies is driving me insane

you guys rock

[tame slate]

it just streamlines the linking of those packages together, doing a lot of the common things you have to do across those packages automatically or within a single call

[tame slate]

Lobby can be a pain to work with and now that the above package is out, there's really no need to use Lobby directly unless you need lower level access for a highly customized solution - even then with all the constant updates that Sessions is getting nowadays, that's becoming less and less true as well

[sharp axle]

Check out the Widgets Package as well. It has a Session Viewer UI prefab you can use as a Lobby Browser

[normal bluff]

Im.... so effing glad i asked questions here first. This is a life saver.... thank you

is the widgets package i nthe package manager. I dont see it

[tame slate]

Sessions came out after I made an entire Lobby system from start to finish lol

[tame slate]

https://docs.unity3d.com/Packages/com.unity.multiplayer.widgets@1.0/manual/install-widgets.html

there's steps there to add it by name

com.unity.multiplayer.widgets

[normal bluff]

OOF

[sharp axle]

You can get it from the Multiplayer Center as well or install it by name

[normal bluff]

ah okay. I got it now. Im excited. I'll actually be able to get passed the lobby thing and go back to the fun stuff

[sharp axle]

They are excellent for getting up and started quickly, but they are not very customizable at the moment.

[normal bluff]

well this still will help a lot. i jsut need a lobby system so i can start testing with real people. and this was holding me abck big time

[sharp axle]

For quick and dirty testing just slap a Quick Join Session widget and go

[sharp axle]

There is a Unity Netcode Discord Server in the pinned message here.

[normal bluff]

Just messed with the widgets... I'm gonna go ahead and delete the lobby stuff. THis is so much better

[normal bluff]

I think ive got it. i jsut cant figure out how to access the data from playerpropertieschanged. Any idea?

[sharp axle]

You would need to loop through currentSession.Players.Properties[]
You might need to call currentSession.Refresh() first.

[winged ember]

I am using Multiplayer Play Mode. Any time I do some code changes it says that the Network Configuration doesn't match, then I have to restart Unity and it starts working. Is there anything specific I have to do so I don't have to restart the editor?

[normal bluff]

Do i call currentSession.Refresh() inside PlayerPropertiesCHanged method?

[normal bluff]

I find with Multipler Play mode if i make a lot of changes to the code i have to uncheck the other player so the instance closes and recheck it. It rebuilds the instance including any changes

[sharp axle]

That should work

[sharp axle]

Make sure you have domain reload turned on so everything recompiles on changes

[fluid walrus]

i've had a lot of problems with MPPM not triggering a domain reload on code changes on the secondary players 😦

[winged ember]

Looked at my settings and it is set to reload by default, so it doesn't help. Unchecking and rechecking the other player did work

[sharp axle]

Yea. I think this is the main issue. Not sure what causes it though.

[fluid walrus]

i guess it's something to do with the asset database on the others not being told about changes, hopefully something they'll iron out over time

[normal bluff]

I finished writing the session/lobby code. Works great but im having one issue. When the host joins the player properties are added jsut fine. But when another player joins the player property PlayerReady doesnt seem to be getting added for that player. I can see it happening in the OnEnterSession method though

[mint anvil]

quick question if i pick up a gun, the weaponholder has to have a network object as well as the player itself (so two?)

[normal bluff]

the gun, the player (and unit if the player is jsut a camera controlling the unit i.e. a tactics game) has to have a networkobject component

[mint anvil]

yeah but i dont set the gun as a child of the player itself but to the weaponholder (hands) which are a child of the player

and this requires a network object ig

[sharp axle]

I would use physics joints to attach the object to the player hand instead of reparenting

[mint anvil]

uh but my system, where the animations of the gun (including the hands) are stored on the gun, and at spawn, the players animation controller is set to the gun's one, means the gun HAS to be in the hands to be animated

[sharp axle]

Its a bit trickier but still doable without the gun being a child of the player. If you spawn the gun with ownership the gun itself can find its owner's player object and set its animation controller accordingly

[sharp axle]

I believe this should work. Which callback isn't getting triggered?

[tame slate]

is the actual property itself not being set or is your UI just not reflecting the property's changes for the joining player

[mint anvil]

uuurgh can't i just give the weaponholder a network object?

[sharp axle]

nope. Network object parenting is a bit complicated

[mint anvil]

RAAAAH

yeah idk how to solve this lol

[mint anvil]

yeah but the animations wont work if the hirarchy is wrong right? if the gun and its parts is not in the hands, the gun animations won't work

[sharp axle]

If you are replacing the player's runtime animator controller, it won't care about the hierarchy. You just have to make sure the gun is in the right spot.

[mint anvil]

that's not true? if the gun is not in the hands anymore, the animation can't find the gun

(visible with yellow text in the animation)

[tame slate]

it would be quite easy to seperate those animations tbh

if they're seperate objects the animation shouldn't really me jammed together in to one file anyway

[sharp axle]

I don't know how your system is setup, but the gun's OnNetworkSpawn() should be able to link things together if need be

[mint anvil]

not really

[tame slate]

You can copy and paste keyframes between anim files

[mint anvil]

what the f- no that is way too much work, the point of the game is 100s of unique weapons

i animate everything related to a weapon in the same animation controller, then at start slap it onto the player. this works perfectly, but with netcode apparently not because of parenting when spawning the weapon

[mint anvil]

i don't really understand either, if i move the gun out of the hands, the gun is not a child of the animator anymore and won't work or am i missing something here

[tame slate]

Setting up 100s of different weapons to be reliant on another model within their animations is not something I'd recommend - for offline development or multiplayer development

[mint anvil]

it's really simple, the hirarchy of the hands just has to be the same

then it will work

and i am not planning to change them

so this system will work

i hate the approach of first person models/animations not being the same as third person ones, that's too much work and just dumb

[sharp axle]

I was referring to using an AnimatorOverrideController

[mint anvil]

dies

[mint anvil]

yeah i dont see how that would help

[mint anvil]

what if i spawn an emtpy object with the script of the gun on the player, then spawn the gun model itself in the weaponholder with an rpc sendto.everyone?
btw, if i swap a weapon, can i just disable a network object in netcode or is that not possible (respawning would be dumb) or i disable the model and set a bool usable to false

[sharp axle]

The network object need to be remain enabled if it has RPCs or network variables on the object. If it doesn't have either then it might not need to be a network object at all. Just use an RPCs to Instantiate the gun object on each client for that player.

[mint anvil]

well a weapon with rpcs to shoots / attack or use abilities of it, need a network object tho i guess
or i use an interface to run the shoot function with a gun controller on the each gun, but idk if i am thinking far enough rn or if it will create problems later

[sharp axle]

Those Rpcs could be on the player instead. Leaving the weapon as a regular game object

[mint anvil]

indeed i did not think far enough. players who join later won't see the other player's weapons

[winged ember]

how do you organize code when you want to make local multiplayer and P2P multiplayer?
for example: player object that holds some properties and can spawn animals in the world.
edit: give me a an hour to actually figure out what my problem is 😅

[tame slate]

I usually tend to make the "Player Object" represent a connection/machine in an abstract way. This object will search/listen for different sources of input and create actual playable character objects in the game for each input (ex. player character object for each controller plugged in).

[winged ember]

so what makes my brain melt is that I can just use the direct object reference in local multiplayer, but in a networked version I don't know how I get the actual objects using the ClientID
also, how do you make both work? My current version was built for local multiplayer only
I think I have to create 2 player objects/prefabs one without a networkObjectComponent and one with it. For the networked version I then have to move the logic to a networkBehaviour and make it use the ClientID instead of the direct object reference. Then, depending on the play mode, I choose the prefab to use, right?

[tame slate]

The reason I recommended the solution above is because it avoids any need for separation of code or prefabs. If you're going to create and maintain what is essentially two separate versions of the game, that's a lot of work.

The other benefit to what I suggested is that it allows you to connect a client to an online game with 2 players. So you're able to do fully local offline multiplayer with two players on one machine, as well as connect those two players to an online game.

[winged ember]

Is there an example of that somewhere? starting out with things and the light bulb is just starting to flicker (just yesterday I learned how to actually use the newtwork prefabs list and how to instantiate+spawn things)

[tame slate]

I'm not too sure. Probably would be hard to find. Especially one that exactly matches your setup. But honestly I would say it's not too hard.

The main things to focus on are:

• One object that represents the connection/machine. This object can be pretty barebones as it only has a couple responsibilities. Connecting/disconnecting, listening for input sources, requesting playable character objects to be spawned by the server when an input is found and storing these character objects.
• Your actual playable character objects don't actually need too much special consideration. As long as you spawn them with ownership and correctly map an input source to them, they can handle pretty much all of their own networking logic themselves.

[winged ember]

Ok, now it really sounds easy. I guess I can google how to get object references with clientId
Thanks so far 🙇‍♂️

[tame slate]

Are you using NGO?

If you spawn the connection/input manager object as a Player Object, you can get it via:
NetworkManager.Singleton.ConnectedClients[clientId].PlayerObject;

and then if you store reference to the playable character objects in a script on the connection/input manager, you'd also be able to access them with only clientId

[normal bluff]

My UI changes aren’t reflecting

[normal bluff]

The property is definitely getting changed but my UI isn’t reflecting it. Could be a race condition but I don’t know how to test it

[normal bluff]

Nvm. my logic was just bad. If this helps anyone, this is the working code:

[normal bluff]

How do i set the property of the session itself? I see ISession.Properties but i dont see any overloads

[sharp axle]

The session owner can do that. session.AsHost().SetProperty()

[normal bluff]

Brilliant! How did you figure that out so easily? Im looking at the page and i dont actually see that you have to use AsHost() first

[sharp axle]

lol, I'm a mod over on the Unity Netcode Server We've been digging through the docs for some time now.

[normal bluff]

Ah! okay that makes sense.lol

if (AuthenticationService.Instance.PlayerId == currentSession.Host)
{
    //host sets the session "SceneToLoad" property
    currentSession.AsHost().SetProperty("SceneToLoad", new("Battle"));
    await currentSession.RefreshAsync();
}```

This doesn't call UpdateSessionProperties for me. Im sure I did something wrong but i cant see what

I just debug.logged it and the property isnt getting set for some reason:

[normal bluff]

It should porbably be "SavePropertiesAsync()". I'll try that

Yea it was that. Thanks @sharp axle

[split hedge]

Why is this giving me an error?

[sharp axle]

Are you calling this in Awake()?

[split hedge]

Nope, a button.

[split hedge]

Just an 'Authenticate' button

oh wait no, this gives me the error when I try to create a new lobby

[sharp axle]

That error means your CreateLobby() is getting called before the Unity Services are Initialized

[split hedge]

How may I fix that?

[sharp axle]

You can call your Authenticat() in your CreateLobby() before you CreateLobbyAsync

[split hedge]

Currently that function is called when a button is pressed, i dont think it'd be a good idea to change that

[tardy mist]

does anyone know of a good networking solution that has steam integration and would work well with visual scripting? i've messed around with fishnet, but a lot of the actual networking from what i can tell can only be done in actual c#

[sharp axle]

https://assetstore.unity.com/packages/tools/visual-scripting/multiplayer-with-visual-scripting-226003

[mint anvil]

ok i did that now and it works. the only problem there now, is that i don't know how to handle weapons like bows -> where i have to hold the mouse (play and hold an animation) and then release and shoot, if i use an rpc to run the shoot function of the weapon interface

[sharp axle]

I would use a network variable for that. It can be a bool called WeaponCharging/Drawn/Loaded whatever. If it goes from True to False then you call Shoot()

[mossy bluff]

i have a networkvalue that i think its properly implemented, but it is always 2 out on the client.. its like the first 2 decrements dont work.

[sharp axle]

Network Variables are sent reliably and are guaranteed to be in sync

[mossy bluff]

thanks, yes i think it was just when i was printing them

thatsamazing, theyve made it easy, otherday i was confused by that lobby that as u said was over engineered, writing a simple one now.

[mossy bluff]

im trying to add something to a NetworkList but i get a null when i do, error copmes from inside NetworkList inside add, if (!CanClientWrite(m_NetworkManager.LocalClientId))

but the list is initialised already, any idea why its null there?

[sharp axle]

Depends on when you are calling the Add(). You will need to make sure it's after OnNetworkSpawn() has been called.

[mossy bluff]

Thanks a lot!

[mint anvil]

I can see myself getting client side prediction working somehow (I am using ngo not entities) but there is no host migration right? Idk if I heard it being in development ... or was I just dreaming

Anyway seems a bit complicated to me, but this feature feels like it makes paying for servers obsolete if the game is not in a huge scale

[mossy bluff]

i have a list of games like this, but for some reason the callback never gets updated when i update the list.. availableGames = new NetworkList<GameInfo>();
availableGames.OnListChanged += OnAvailableGamesChanged;

instead i have to call refresh every few secs, seems wasteful

[mossy bluff]

is there some bug doing something like this? think i saw on forum earlier public struct GameInfo : INetworkSerializable, IEquatable<GameInfo>

[tame slate]

How often do you add to this list?

[mossy bluff]

just once

[tame slate]

You might as well use NetworkVariable instead of NetworkList then

You can just assign the whole list to the NetworkVariable and then you have to call CheckDirtyState on it. I’ve seen people have more luck with this being reliable than NetworkList

[mossy bluff]

oh i mean ultimately id like many games in the list 🙂

[tame slate]

Yeah. You can still have that.

[mossy bluff]

ah nice,

i think im fundamentally confused how this works to be honest, kind of limped through it using copilot

[tame slate]

public NetworkVariable<List<GameInfo>> availableGames = new(new List<GameInfo>());

Should work for you

[mossy bluff]

will try it thanks!

[tame slate]

And then you just have to call availableGames.CheckDirtyState() and OnValueChanged should trigger for it

[mossy bluff]

so why doesnt networklist work do u think?

see all the stuff i did with the list then has errors like add etc

and dont want to change it all unless i know it would work

I`ll maybe come back to this, i should prob rewrite what i have

difficult to test without another ip lol

[tame slate]

I don’t know. I very rarely use it. But I’ve seen many people have issues setting them up. I would check if a NetworkList of a basic type like int works. It might be something to do with serializing GameInfo

[mossy bluff]

Yeh think i did read that somewhere

i think it started when i added name and desc to it

but that was hrs ago so not sure

[split hedge]

Hey, I get no error for this code, I just don't see the client's prefab on the host (and also it doesn't get moved)

[mossy bluff]

does anyone elses unity jerk a lot when testing 2 players? i know its a fast enough computer because sometimes it runs fine

is it listed in network prefabs?

and have a network obj script

im new to this so cant help much lol

[severe abyss]

Hi guys,
I am currently working on a multiplayer game and since yesterday or the day before I am getting this error message when a second player (client) joins my game session via the Lobby Service -> Relay Service...

Does someone know an answer for this issue?

[split hedge]

yeah

[sharp axle]

Make sure that only the host/host is instantiating and spawning the network object

[sharp axle]

This sounds like an issue with he Relay service

[sharp axle]

Report this in the Cloud Dashboard next time you see it. And keep an eye on https://status.unity.com/

[cloud vapor]

guys Im kinda confused, do you use fishnet with heathen or fishysteamworks with heathen because I saw fishnet's website saying fishysteamworks is a wrapper thats compatible with heathen but arent they both wrappers? why would I use both

[viral ether]

sup gang, plz ping me for the reply c: ❤️

I have 50 cards for each of my players
when the deck initializes it takes from those cards and assign them as needed, the card image and such~

now, sometimes I will need to spawn new cards, how should I do this?

I could make the pool bigger, make it 100 card each card pool, but I think I rather have it spawn new card prefabs

something like this

[split hedge]

That means do I do a check for (if IsHost)?

IsOwner prefisely

[sharp axle]

has to be isHost or IsServer. the client can be the owner but can not Spawn objects

[sharp axle]

If you are using Network Object Pool, then it will expand the object pool when you spawn the objects

[split hedge]

Sure

[viral ether]

oi, I will check that out

later tho, today is the presentation XD :'v I'm so nervous, after today I will polish a lot of things and make the game better overall

so that's in the list now

[sand talon]

Hello!
I'm trying to get a little proof of concept for a game working, and i'm having some trouble with synchronization.
I'm using Photon Fusion 2 and the issue i am having is that if i quickly tap any directional key, the Direction value quickly switches back and forth between the previous, and target direction as if it can't decide which direction to apply. This only happens on Non-Host clients.
mu_playerDrawer class is only responsible for displaying the changes, and doesn't modify the networked values or calls any RPCs, so i hope it's not important in this issue.

[winter peak]

soo when I have network object which has network objects parented into that how I can spawn them also when spawning root

its any easy way via some setting?

these doors

[winter peak]

I cant have network objects already in prefab as parents?

seems like all these objects have same global id hash

Server spawns room

Room ( Prefab and NetworkObject )
- SomeObject
-- Door1 ( Prefab + Network Object )

[winter peak]

In this case I can just remove network objects on parent ones when root has one?

[sharp axle]

You have to spawn them both separately then you can reprarent them afterwards if you really need to. Or you can remove the network object from the child object

[winter peak]

hmm trying to connect to server but theres no reaction on other end

[sharp axle]

You are running the server on the same local machine?

[ocean wadi]

Hi, so I am currently getting delayed spawning of objects between my host and client when they are running on the same local machine. The difference is spawning is noticable and longer than a frame. All my settings appears to be correct and should not be introducing any lag, I was wondering what some reasons for this latency could be? Could it have to do with differing framerate? I'm pretty new to networking so I feel like it is a very simple fix, but I don't really know what to be looking for.

[tame slate]

You're still going through your local network which is subject to latency, it's never going to be instant.

[ocean wadi]

Shouldn't the latency be at least not noticeable and within a frame of each other? Currently the delay is noticeable especially if you place both windows side by side and look at the spawning of the objects on both.

[sly lily]

Hi, ive only used unity netcode to build my multiplayer games but i looked at photon and saw this. Does photon do all of this stuff by itself or is it like really easy to implement? Because in netcode you would have to do this all by yourself which would be very very hard. Like Client side prediction or lag compensation.

if it really that easy i might actually switch

[tame slate]

I mean it shouldn't be anything crazy, but if it's between 10-20ms I would say that's not really of any concern.

[tame slate]

"by itself" is a bit of a misnomer. They provide these features for you to work with out of box. Meaning you don't have to implement them from scratch. You still have to work with the features to integrate them in to your gameplay code.

There are also other considerations like when using Quantum, you are required to use their physics system and are unable to use Unity's physics.

[sly lily]

yes, but how much time does that save you? I would say a lot. I dont even know how i would build Client side prediction or lag compensation from scratch in netcode and i didnt seem to find any useful tutorials on it either. And these things are practically necessary, i mean a game without client side prediction is basically unplayable and an FPS game without lag compensation is also unplayable.

if there was like an asset or something that would do this in netcode i wouldnt even think about switching

[tame slate]

In theory, lots. Most of those features aren't simple topics. Was mainly answering your question of:

Does photon do all of this stuff by itself

Which is no, as I explained above. I would look at reviews and tutorials to gauge how easy people find those features to use. That will give you a better idea of if it's worth switching or not.

Depending how how important pinpoint accuracy and anti-cheat is, you could make a respectable small-scale casual FPS experience in NGO using Client Anticipation and by implementing a basic Lag Compensation system which I would say is not too hard to do with NGO.

[sly lily]

i just looked at the photon docs and it seems pretty clear and simple. Unlike unity they actually give good examples that are easy to understand. But i also dont really want to switch and re-learn all the stuff i already know. The client anticipation you send me looks kinda hard and i have no idea how to make lag compensation

Also my game could be client authoritative, which would delete the need for client prediction, but i would still have to make lag compensation

[tame slate]

There's a sample from Unity about Client Anticipation and there's plenty of resources online regarding lag compensation. Even ones that implement it within Unity

[sly lily]

okay, i will look into that and also photon brags a lot about their extremely good performance, would NGO have some issues with performance if you had like 5-10 people on a server with lag compensation etc...?

[tame slate]

I wouldn't think so.

[dry maple]

Where did you hear it's really easy to implement?

Not sure what you mean actually

[sly lily]

well they have a dedicated implementation for it

and detailed documentation on how to implement it to your game

[dry maple]

No, you wouldn't implement it, you would use it. Your wording is confusing

[sly lily]

yeah thats what i meant

[dry maple]

And yea, they make it pretty easy to do CSP, and the rest.

[dry maple]

a game without client side prediction is basically unplayable and an FPS game without lag compensation is also unplayable.

This is not true

There are tons of games that do not do any of these

and they are playable

COD and BF don't even do lag compensation. They do a broad phase sanity check.

[sly lily]

if you had a server authoritative game you NEED to have client side prediction otherwise you would have huge delay on your own movement etc... and without lag compensation you wouldnt hit any target if it was moving and some speed.

[sly lily]

i dont know what broad phase sanity check is

[dry maple]

I know, I meant in general, but yes, you would need CSP if you are running full server-auth.

[dry maple]

They let the client do a client-side check, and they make sure it's within reasonable bounds in the server (not shooting through walls, etc)

But yea, pure lag comp is a lot better. Because with this method, the devs usually do random things like artificially worsening the hit-reg of players with bad connections which is awful.

[sly lily]

so thats why there are so many cheaters in COD

[dry maple]

No, two of the most important cheats are almost fully unpreventable: aimbots and wallhacks (seeing through walls).

There are ways to try to detect aimbots using Machine Learning, but it still flags good players as cheaters, it's not reliable. And people have already found ways to completely go around the kernel anti cheats, etc.

Going full server-auth will not eliminate these two types of hacks.

[sly lily]

world of tanks actually has a solution for wallhacks - it doesnt spawn the players when they are not visible

and they also dont have client side prediction so the delay on your own input is just awful

[dry maple]

Yea that's one way to deal with wallhacks, Valorant does this too. But this solution does not fully solve the problem, because, due to latency, you still have to send objects within a big range, to avoid the issue where you move around a corner and suddenly see someone pops in front of you, etc.

[normal bluff]

I've been away for a long time. In easing back into multiplayer im learning that you need to NetworkObject.spawn anything with a networkobject or your RPCs wont work. Is there a way to just have those objects in the scene already and assign ownership to the host? Spawning them destroys the object refereences

[tame slate]

NetworkObjects placed in scene before runtime get spawned automatically.

I believe you have to have something checked on NetworkManager, maybe Scene Management, but I believe whatever it is is on by default.

[normal bluff]

Ohhhh!! Which one is it?

[tame slate]

NetworkManager, not NetworkObject.

[normal bluff]

Oh ! Sorry let me check

[sharp axle]

You'll also need to make sure that if you are loading the scene, you are using the Network Manager Scene Manager

[normal bluff]

THATS the problem!!!! Dear god I was going crazy. When I would run the scene as is the game worked. But if I came from another scene? Fail

Thanks guys

Hey, how do I sync playerNames displayed with a TMPUGUI on the player's head? Also how do I sync material colors?

[tame slate]

What library/solution?

[split hedge]

NGO

[tame slate]

NetworkVariable

[split hedge]

So I create a string networkvariable for every playername then?

[tame slate]

Well I would make one NetworkVariable that's in a script that is attached to the player prefab

and you have to use FixedString, not string

[split hedge]

Why's that?

[split hedge]

And so make the script a networkbehaviour

[viral ether]

sup gang c:

I have this script where I call SetPlayer

I have (2) PlayerHandlers btw

and this function, "SetPlayer does get called

I can confirm that cause I debugged and, you can see the "IsPlayerOwned" is been toggled on the correct player

HOWEVER! <=

it's only doing the other part, the serverrpc and such for the host

🤔 I guess it's cause I'm calling it too soon....

when it hasn't determined which player is which yet...

no clue.... 😦

[ocean wadi]

Hi! So I had a question regarding scene management. When I am transition from the starting scene to scene B, I just walk through a portal. After walking through the portal my game freezes for a bit, which will be fixed later and probably covered with a loading screen, but that is not the problem. The problem is that when the client or the host interact with the portal the host's game freezes and start transitioning to the next scene, but the client's game does not. AFTER the host's game has fully transitioned to the next scene, the client's game freezes and begins transitioning to the next scene. I was wondering if this is normal or if there is an easy way that I am missing to make it so that the host and client begin transition at somewhat similar times.

[deep wasp]

Hello guys, i need ur help !
I'm trying to make the player able to hold an item in hand.
As i'm using netcode, i can't parent the network pickable object.
So, how can I do ?
I was thinking about making two prefabs of the pickable object : one that is networked and one not. Is this the right way ? Any alternatives ?

[split hedge]

What you do is make a transform that the object should follow in an update usually

[tame slate]

If there's not a lot of different types of objects, fake it without a NetworkObject - if there is, use joints.

[deep wasp]

I have a lot of different types of objects.
I already tried to use joints, but there are jerks

[deep wasp]

really ? it might overload the network, no ?

[split hedge]

It wouldn't actually

[tame slate]

Even with a lot of objects, faking it is still an option.

and usually makes any animations/transitions of picking up/dropping/interacting seem a lot smoother

[deep wasp]

thanks for answering guys, appreciate it!

[deep wasp]

so create two prefabs for each of my pickable objects, right ? 🥲

[split hedge]

No, don't do that imo

[tame slate]

That would be the most cumbersome way of faking it, but yeah.

Other ways would be having a gameobject pre attached to the hand that has all of your grabbable objects disabled so they’re ready to be enable when something is picked up

You could also make a dynamic system that detects what mesh is being picked up at runtime

And then instantiates it locally on every client instead of doing it via NetworkObject.Spawn()

[deep wasp]

Oh, could be the best idea

[tame slate]

The only real reason to do reparenting or joints is usually VR where you have to be able to swing the object around dynamically with your hands - “faking” it allows things to seem more responsive and lets you be more in control of the interactions

[deep wasp]

Thanks for answering man, i'll try!

[ocean wadi]

So I am working with syncing up dashing effects right now between the host and client in a peer to peer game. I am running two instances on the same machine so I'm pretty sure this much of a difference between the host and the client should not be happening. The two images below are of the client's player.

The image on the left is the client player on the host's screen, and the one on the right is the client player on the client's screen.

Pretty much how the effect is created is through my object pooling system, where if the client dashes, it requests for the object to be spawned and then synced using .Spawn on the server/host side.

[tame slate]

That's not a crazy amount of delay - even when testing on the same machine you're always going to see some delay.

I think you're going about syncing this effect in a way that's overly complicated. There's not much reason why this effect would requires the server to .Spawn NetworkObjects for this. I would look at simply using a NetworkVariable or an RPC to indicate to all clients that this player object is dashing. Once clients receive this update, they can locally instantiate the phantom clones of the player sprite to create the dashing effect. This will always result in the effect appearing right behind the dashing player.

[ocean wadi]

Ahh gotcha tyty ^^

If you want to roll back during an animation then you would need to write your own animator using the Playables API.

Hello everyone, i have created a multiplayer chess game in unity, and for that i need timers, but the problem is each player in chess needs to have their own timer, and every time it's their turn their timer should start and the other players timer should stop, these times needs to be synched on both sides, how can i implement this using internet time or an NTP server or any other way ???

is anyone here created a turn based multiplayer game that needed timer? if so how did you manage to do that ???

[tame slate]

How is your game networked?

[split sonnet]

i'm using nakama relayed multiplayer

[sharp axle]

Your server/host will be the source of Time for the match. I don't use Nakama but there should be a way to send Timer start and stop messages to and from the server. If you really need to prevent cheating then you can use a cloud service to store match times.

[tame slate]

Do they own the NetworkObject that has the NetworkBehaviour with playerName in it?

[split hedge]

No they don't, how do I make them own it?

Those are scene objects

[tame slate]

Probably by sending an RPC to the server when they join to get the server to assign Ownership to them

[split hedge]

Yeah sure but whats the code behind the ownership?

[tame slate]

https://docs-multiplayer.unity3d.com/netcode/1.11.0/about/ Documentation is your best friend for that 😛

[sharp axle]

Scene Objects are owned by the server/host. You can change ownership with GetComponent<NetworkObject>().ChangeOwnership(clientId);

[ocean wadi]

Hi! So I am currently converting my single player combat system into multiplayer. I am working on just syncing character stats such as max health right now. My stat system right now pretty much has a main character stat manager called CharacterStats which houses a bunch of Stat variables, which is a custom class that has a bunch of important methods such as GetBaseValue and AddModifiers. I would want to maintain this custom Stat class and modifier system, but how would I even start with converting this system to multiplayer? I was thinking of creating a custom NetworkStat script where the main value is a NetworkVariable, however, wouldn't this require it to inherit from NetworkBehavior and require an actual component rather than just data values like in my Stat class?

[sharp axle]

You will likely have to rewrite a lot of your systems. You could make your stats a Struct that implements INetworkSerializable. You could then use Custom Messages if you don't want to deal with Network Objects

[hasty sky]

Could anyone please explain me where I am doing mistake?

^ welp no clue, but I do have another question

I usually do ServerRpc > ClientRpc > Local function

I assume I don't need that third local function, I could put everything inside the ClientRpc. Is that correct?

You can use the Relay and Lobby system for that. Check out Multiplayer Services sessions and the widgets to get started quickly

[sharp axle]

You could do it all in one function with [Rpc(SendTo.Everyone)]

Might be slightly unrelated but does anyone know the name of relay servers that hold the ip, port and name of servers for players to request a server list?

Yea. lots of things use Master Servers but that is indeed what they are called in Game Dev too

[sharp axle]

Hello i am trying to make a grappling hook tag game

[azure solstice]

I am using Relay/Lobby to create/connect to game for a two player game. I had someone reach out saying they couldn't connect to their spouse. Is this just an issue because they are on the same IP address? Or how does this work exactly?

[sharp axle]

It would only be an issue if they are on the same machine. Or I guess logged into the same Unity Authentication account

[azure solstice]

Hm, anything else to point to causing that issue then? As soon as I had one of them disconnect from the wifi, they said it worked/helped.

[sharp axle]

I guess it would depend on the error. Being on the same LAN doesn't normally cause any issues

[azure solstice]

I just have it set to play vs AI if they are waiting for a random time between 8-12 seconds or so, and they both just end up in AI games on LAN.

[sharp axle]

Their wifi could just be garbage if its working on ethernet/cellular

[azure solstice]

private async Task<Lobby> QuickJoinOrCreateLobby()
{
    Lobby lobby = null;
    int attempts = 4; // Number of join attempts before creating a lobby
    
    for (int i = 0; i < attempts; i++)
    {
        lobby = await QuickJoinLobby();
        if (lobby != null) return lobby; // If found, return the joined lobby
        
        await Task.Delay(500); // Short delay before retrying
    }
    
    return await CreateLobby(); // If no lobby is found, create a new one
}

It may have just been luck. a 2 second window seems pretty tight here. Any suggestions on how this is normally handled? It tries 4 times, once every .5 seconds to join an existing lobby otherwise it creates one.

@sharp axle

[sharp axle]

You'll probably want a Lobby browser for when people want to pick a match themselves. But I've been using the Multiplayer Services SDK sessions CreateOrJoinSessionAsync(). It also supports matchmaking.

[azure solstice]

It's for matchmaking, so it wouldn't be a browser for this. I was mostly just asking how long I should "look" for a lobby before creating one.

[sharp axle]

Honestly just looking once for open lobbies should be enough. If it comes up empty, its not likely to find one .5 sec later

Is changing network variable write permissions after initialization supported? I changed a network variable's writing permission from server to owner, but I'm finding that the variable is no longer being synchronized over the network. Is there a way to restore synchronization or is this unintended behavior from changing permissions?

[tame slate]

Why do you want to change it after initialization?

[ivory oasis]

Essentially, I have a parent class whose network variables are set to server perms, but I want its child classes to let owners have permission.

Unity has a problem when I try to hide the members in the child classes, so I resorted to setting the perms manually in the start method

[tame slate]

I’m still not really understanding why this has to be done at runtime. Why not just set the write permissions to Owner on initialization?

[ivory oasis]

This is thrown when I try to set the permission to owner on initialization

Left is the parent class, right is the child class

[tame slate]

I was suggesting setting it in the parent class only

as Owner write perms

I don’t think Owner write perms precludes the server from writing to it. As long as the server owns the object.

[ivory oasis]

Thing is though, the permissions are working as expected; I tested that only owners can modify the values in the child class where the server can't, and vice versa. The only issue I see with this is that the values are not being synchronized between the server and client.

[tame slate]

Which I would say is a pretty good indication that it’s probably not supported unfortunately.

[ivory oasis]

aiyah probably :(

Any workarounds you can suggest maybe?

Worst case scenario is that I just make two separate health systems for NPCs and players, but I'd like to have a unified system if I can

[tame slate]

I would just choose one set of write perms, declare it on the parents initialization only and set it accordingly.

[sharp axle]

You don't have to initialize health in the base class

just do it in the OnNetworkSpawn() and set it to whatever you need there

[ivory oasis]

I'll fiddle with these ideas, thanks for the help 😊

[ivory oasis]

Alright, so turns out the proper way to set network permissions of inherited network variables is through the Awake method, which I actually did do, but I made a logic error so I thought it was incorrect. 🤦‍♂️

Synchronization works and everything!

[rare lava]

Hey guys, wondering if anyone would have any idea of how to debug something like that.
I have a linux Unity running and webgl instance.
I'm using NGO with Unity Transport configured for wss.
It works well where there are not too many people. But after like 10/15 people, I get messages like:

"CompleteSend failed with the following error code: -5"
and
"Error sending message: Unable to queue packet in the transport. Likely caused by send queue size ('Max Send Queue Size') being too small."

They are flooding the logs. Doesn't seem to be any other error.
Soon, the players cannot connect anymore. And after a while, the server seems to shut down, for everyone.

I did update Unity Transport to the latest and tried to change some of the values but it doesn't seem to help 😦

Any ideas?

[sharp axle]

You can increase the message queue size but you are likely just sending too much data per frame. The server/lhost is timing out because the network is clogged

[rare lava]

Thanks!
Could this be because I have too many users or could this be a very bad RPC that sends too much stuff ?
I just send basic data, like the player's position, and some RPC when they are interacting
But maybe 15/20 users is already too much for the server.
Is there a way to detect when this happens and to prevent it?
I did try to increase the message send queue size but yeah, doesn't fix the issue

[sharp axle]

Probably just too many users. If you have a lot of moving network transforms then every player has to get all those positions every frame. You can use NetworkHide/Show() to have the clients only receive what is important to them.
https://docs-multiplayer.unity3d.com/netcode/current/basics/object-visibility/

[rare lava]

Thank you very much, I'll look that up

[peak pulsar]

Hey. I am trying to set the spawnpoint for my co op game (two players), but for some reason it only works about half of the time
I have the default positions in ApprovalCheck and no other place to change the default position
I always get the expected values from the spawnpoint and it seems to be setting it because the player spawns in the correct place, but then teleports to 0 0 0

[sharp axle]

That can happen when using Client Network Transform. the server does not have permissions to change the player's position. I would use OnNetworkSpawn() on the player to set the spawnpoint

[peak pulsar]

Sorry for late reply, I am using Network Transform
This did not fix my issue, still spawning at 0 0 0

[sharp axle]

What version of NGO are you using?

[peak pulsar]

2.11

Unity 6

This is my quick and dirty fix
It runs on the player prefab

(seems to be a bug where it runs host as well as client, but the hostSpawnpoint and clientSpawnpoint are working)

[tame slate]

That's not a bug. You're just not checking to see if it's the local player before assigning position/rotation.

[peak pulsar]

I meant there is a bug in my code, not anything to do with NGO

[sharp axle]

This is the way I would do it(while checking for IsLocalPlayer). But is your Network Transform set to Server Authority or Owner?

[peak pulsar]

It is set to server

nvm, its set to owner

was testing it a bit so I had it set to the wrong value

Checking like this fixed the bug with it running multiple times for the client, thanks

will test it a bit to see if it fixed the spawnpoints

nope, did not fix it, but at least now its only running once

[tame slate]

You're on NGO 2.1.1 so trying that in OnNetworkPostSpawn instead might work?

[peak pulsar]

I'll give it a go

[sharp axle]

This will work only if the Transform is set to Owner Authority. If its set to server then you need to move with an RPC

[peak pulsar]

doesnt seem like I have access to it

[tame slate]

I believe it's a protected method, not a public one.

[peak pulsar]

Yeah, I am using owner and everything is set up to work with it currently

[peak pulsar]

Yes, you are correct

OnNetworkPostSpawn did not fix it unfortunatly

[tame slate]

That leads me to believe you got something else going on on your end, either in the set up of your components or in your code. Position being set in Post Spawn should not be being overwritten by anything on NGOs end.

Does your movement code for the players work properly?

[sharp axle]

Definitely something else going on there. That code will work

[peak pulsar]

my movement code is very simple

I can try disabling scripts on my player prefab

got it to work 5 times in row when I disabled my scripts, seems like something I doing wrong

[tame slate]

I believe you should also be using .Teleport on the NetworkTransform instead of setting the position on the transform directly. Setting it directly will be subject to interpolation. But that's probably unrelated to your current issue.

[sharp axle]

make sure to disable the character controller on the remote players. it will override the network transform

[peak pulsar]

ok, will try both

[peak pulsar]

Getting an error, how can I get authority?

[tame slate]

You call teleport on the authority

which is determined by what you have it set to on the Component

I belive you said it's Owner

[peak pulsar]

yes, it is owner

So kind of like this?

or am I misunderstanding something?

Still getting the error even thought the player is the owner :/

I got it to work by only enabling charactercontroller and movement script for the playing player
Thanks for the help 😊

[viral ether]

hello gang

the rpc send to everyone

requires ownership?

like I did in the function below

[tame slate]

I'm pretty sure it's false by default when you use the new attributes

[viral ether]

oh cool

and is it the same as it was 🤔

one second let me get those professional graphics to explain myself

with Server > Client > Local function rpcs

no matter who called the function, it would be... casted by the server/host player

is it still the same with the new attributes?

or now, if I put "GetCurrentPlayerData" inside of it, it would get each player's data

if I misexplained myself, excuses. I'm tired and braindead at this point

[tame slate]

No underlying functionality really changes with the new system. It's simply a convenience update to make sending to specific targets or target groups easier.

Client to client RPCs are possible with the new system, but as mentioned above this isn't an underlying change as the RPC still has to go to the server in the middle of this process.

[viral ether]

oh cool! ❤️

thanks for answering :3

"meow" and "uwu" type thing

[wispy isle]

So, I’ve run into an odd issue. I wrote a little networking prototype, it was working flawlessly, but suddenly clients can no longer connect. The console says the connection is going through but the screen stays black and no player spawns. Hosts client works fine, but no other clients will spawn.

I’ve tried starting my computer, double checked network manager. Again no changes were made literally just stopped. Any suggestions or thoughts on what I can try?

[sharp axle]

Are you using NGO? Are the clients on separate PCs?are any error messages showing on the client?

[wispy isle]

Yes using NGO. Clients are running on my machine, using the Unity multiplayer play mode. No errors from the client, even says that they have been connected but it never gets to the player spawn. It’s very odd

[edgy tiger]

Hi, I've got a strange issue with my game, where when the players spawn in, the host spawns in the correct position, whereas the client moves to 0,0,0. The player objects work by using a sphere to calculate physics, and the player model is teleported there. The sphere is deparented on start, and has a network rigidbody and client network transform. This happens inconsistently, and doesn't happen when i disable the rigidbody on the sphere. Does anyone have any ideas of what this could be?

[sharp axle]

Are you automatically spawning the player object with the network manager? Or are you doing it manually?

[sharp axle]

Are you using Connection Approval or OnNetworkSpawn to set the spawn position? I've seen where rigidbody interpolation can cause issues like this but I thought that was fixed a while ago.

[edgy tiger]

OnNetworkSpawn i spawn it on the host then set the owner to the correct clientId

The thing is, i know it spawns in the correct position because at first, i stop the player from moving until the countdown ends

As soon as it can move, it does it

Is there any way i can fix the interpolation? It seems to work when i turn it off but its really jittery

[tame slate]

How are you teleporting the player?

[edgy tiger]

I apply forces to the sphere and the player model sets it's position to the spheres position

The sphere's the only one with a rigidbody

[tame slate]

If you want an instant change in position, you should use NetworkTransform.Teleport as opposed to setting the position of the transform directly.

Teleport isn't subject to interpolation, even when interpolation is on.

[edgy tiger]

Ah okay ill change that

[white meadow]

hi, where I can find any tutorial on new unity3d multiplayer center (so also networking in that, how works, create lobby etc. not just using scenes that unity have for multiplayer - wanna understand how it works)

[sharp axle]

Its still pretty new so there is not a whole lot out there. There are the Unite talks. I made a video on it that was linked here a few days back. You can check out the Widgets from the Quickstart tab in the MPC

[white meadow]

can you give me link on priv? cant find

[sharp axle]

This is the latest one #archived-networking message

[mossy wing]

I know this isn't related to unity but how do I use a DNS as a website URL?

[sharp axle]

What exactly are you trying to do?

[mossy wing]

Never mind, I figured it out.

[magic yarrow]

Can someone explain me, why only my host can grab and change position of object, when im trying to grab something on client its not working

[hearty dock]

Anyone know where I can find release notes for NGO 2.1? I don't see them here. https://docs-multiplayer.unity3d.com/netcode/current/release-notes/ngo-changelog/

Nevermind - found it from a link in the package manager https://docs.unity3d.com/Packages/com.unity.netcode.gameobjects@2.1/changelog/CHANGELOG.html

[wild turtle]

do you guys know where I can get started with Unity 6 networking, especially for using Steam?

[sharp axle]

For Unity Netcode for Game objects. Follow the quick start guide and read through the docs
https://docs-multiplayer.unity3d.com/netcode/current/tutorials/get-started-ngo/

[left kelp]

My network rigidbody doesn't appear to be affected by gravity, and I can't figure out how to actually move it. If I try moving the real rigidbody it doesn't work, and even though gravity is checked it doesn't appear to have gravity.

[sharp axle]

Network Rigidbody is kinematic on clients that are not the owner

[left kelp]

so I need to send movement to the server and have the server move things

[sharp axle]

That or you can request Ownership change from the server

[faint plume]

hello! has anyone tried using CreateOrJoinLobbyAsync ?

when i run it twice with the same parameters i get http error 409 on one of the instances, while i expected it to just join the lobby that the first call created

[sharp axle]

409 is a conflict error. You might still be joined to that lobby. If you drill down into the details of that exception, you should find a more exact message

[faint plume]

Ah that's interesting

[weak plinth]

im trying to make multipalyer with photon and i need to put "if (view.IsMine)" some where so that the players dont meve each other does anyone know where to place this

[haughty heart]

Beginners shouldn't be taking on multiplayer, and people are not going to be super willing to help just knowing the amount of explanation they're going to have to do.

But an obvious place to put that code you think you need, would be in your Update function before you read the input for that character.

[weak plinth]

can u update it?

[haughty heart]

No

[weak plinth]

why

[haughty heart]

Because of what I said here 🫴 #archived-networking message

[weak plinth]

its just a game for my friends and i

please

[tame slate]

He already gave you the answer. Just take a second to read the answer over and try to implement it yourself.

[weak plinth]

but i realy dont get it

[weak plinth]

can u make it?

[tame slate]

No

[weak plinth]

whyyyyyyyyyyyy

[tame slate]

Go download a sample project if you just want it done for you. I have no interest in writing code for someone - especially someone who shows zero interest in attempting to experiment or learn about the topic.

[weak plinth]

i have been trying for over 2 hours

[tame slate]

Such is programming and game development.

You were already given the answer in a pretty clear explanation. If reading that answer really registers nothing for you, you need to take a step back and read/watch some more content about networking and/or Photon.

[faint plume]

how would one as you say "drill down", all i get is: HttpException`1: (409) HTTP/1.1 409 Conflict

[sharp axle]

CreateOrJoinLobbyAsync will throw a LobbyServiceException in a try catch block.
https://docs.unity3d.com/Packages/com.unity.services.lobby@1.2/api/Unity.Services.Lobbies.LobbyServiceException.html

[faint plume]

it looks like WrappedLobbyService already catches it, dunno if i can do that again

guess i can try

ok it did work, it says im already in a lobby

thats peculiar

[sharp axle]

I'm fairly certain it will still bubble up. You can the full detail of lobby errors here
https://docs.unity.com/ugs/en-us/manual/lobby/manual/lobby-error-messages

[faint plume]

Unity.Services.Lobbies.LobbyServiceException: player is already a member of the lobby ---> Unity.Services.Lobbies.Http.HttpException`1[Unity.Services.Lobbies.Models.ErrorStatus]: (409) HTTP/1.1 409 Conflict

i gotta check if i set up unique player ids correctly i guess

i have other code which uses Create and Join separately which already works, so i figured that must be correct, i just figured the combined CreateOrJoin version looked neat

thanks for the help, now i have a lead at least

ok yeah both unity instances for some reason get the same player id, i dont think ive had this happen before

but that must be it then

so the Create & Join separate case that works is using Relay, otherwise its hard to see any difference

maybe the Relay allows me to use two players with the same PlayerId

its interesting that it allows the same playerid. i just found a case in the documentation saying i need to detect this when using ParrelSync and create different profile

anyway, progress!

[sharp axle]

Yea, if you are signing in anonymously on the same PC; you should switch authentication profiles between the instances

[faint plume]

yep, all working now!

thanks a bunch

still a mystery why the old code worked despite being the same playerid

[junior sapphire]

I’m using a linux server and a webgl client with NGO. Just started getting issues where the web client can’t connect to the game (websocket failure) but a unity editor client connects fine. Is it possible that too much network comms, RPCs, NetworkVariables etc could be preventing my browser build from connecting? Or perhaps memory usage is too high for the browser?

[sharp axle]

Network messages aren't send until after connection so it's not problem of flooding the network. Unless it's timing out after connection

[crisp gull]

Can somebody clarify ownership when using network managers PlayerPrefab?

Say I have a player, they spawn and each is assigned a client ID. In the prefab there's child objects such as a light source, ect. Does each client own it's own child's?

Unity 6's visual tool shows that yes, they do but I feel like the server actually owns them..

Any clarification would be nice! What im after is having client authority on some child objects such as the light source

[sharp axle]

The root network object is the owner of any child objects.

[crisp gull]

Got it. I think I figured out the issue. I'm not referencing the network behavior on the parent when I attach a script to the light source..

Also I want it droppable so I gotta dynamically spawn it regardless. If I'm completely wrong please let me know. Thanks

[sharp axle]

Spawned network objects are owned by the server/host by default. Unless you called .SpawnWithOwnership(). Reparenting network objects should change the ownership of them as well. There are easier ways of attaching objects to players with reparenting though

[ocean wadi]

If my understanding of networking is wrong please correct me during my explanation (new to networking). So I am running into an issue in another script called WeaponController, where I need to invoke server rpc (in order to handle attack collision detection purely on the server). In order to invoke a server rpc, I need to first call .Spawn on the object that wants to invoke the rpc, in this case it would be my sword object. The code above is located in my WeaponSwitching script and is in charge of handling the instantiation of the weapon. I am trying to reparent the weapon as a child of the player, however, for some reason the weapon is not being reparented. I pretty much had 2 questions. Is it true that when dealing with nested network objects, you should initially spawn in the child network object as it's own parent and then reparent it manually, as you can run into issues if you directly instantiate a network object as a child of another network object? Additionally, is there a better way than what I am doing right now (I feel like there is a very easy solution that I am missing here)?

[sharp axle]

Yea. You can not spawn a Network Object as a child object. There are other way of attaching an object to a player besides parenting though. You could also have the RPC on the player and not the weapon itself.

[ocean wadi]

I see I see. Is there a reason why the code I sent isn’t working for the reparenting though? Even if I decide not to use reparenting I still am wondering why the object is not being reparented.

[sharp axle]

probably an issue with spawning and reparenting in the same call.

[ocean wadi]

I think I found the issue. Would it be because I am trying to parent the weapon under a child of the player object? Pretty much I have the player object, which is a network object, but I have a child called WeaponHolder under the player, which is not a network object.

[sharp axle]

Yea that would be a problem as well. Network Objects can only be a child of another network object
https://docs-multiplayer.unity3d.com/netcode/current/advanced-topics/networkobject-parenting/

If you are using NGO2.0 then you can use physics joints to attach network objects
https://docs.unity3d.com/Packages/com.unity.netcode.gameobjects@2.0/changelog/CHANGELOG.html#added-5

[ocean wadi]

Ahhh I see I see. You mentioned earlier that there are other ways of attaching objects to the player. I was wondering what common industry practices are for this? Would one way just be to manually update the position of the weapon to follow an anchor point? Would it be easier to just change up my player hiearchy so that the weapon is a direct child of the player (the only point of the WeaponHolder child of the player is really for organization but if I wanted I could pretty easily have the weapon as a direct child)?

[fringe imp]

if im not mistaken you said weapponholder is NOT a network object right? you should be able to parent it to a network object i think, am i wrong @sharp axle ?

just not other way around

[ocean wadi]

ya so the player character is a network object, the player has a child called weaponholder which is not a network object. i am trying to parent a network object weapon onto weapon holder

[fringe imp]

ahh i see. Try making weaponholder a network object, that has a variable for the weapon, does the weapon need to be networked? If so do u mind filling me in why?

[ocean wadi]

I have a script on the weapon that requires RPC calls, specifically for making sure when a collision is detected on the weapon the logic following such as calling damage functions occurs on the server rather than the client. If I'm not mistaken, an object has to be a network object and spawned in order to invoke RPC calls. Also I don't think I can make the weapon holder a network object as the player is spawned into the scene not already part of the scene.

[fringe imp]

ah gotcha. So i usually do this. and this is just advice, im not an expert - Change your way of thinking from weapon holder, make it a weapon controller (networked). Have all of your weapon code on it, have your weapon visual as a child. When you spawn in, in awake or wherever you want just hide the weapon visual.

Separate the visuals. All of your code will still work even if you weapon was a blank space, or a unity cube. Need to change the visual for everyone? Send an rpc that you changed the visual.

[ocean wadi]

Ah I see, so would this mean I would be created a WeaponController object that is separate from the player character (and just have it follow the players hand or something like that)? And when I need to make changes to the weapon, whether it be a buff or equipping another weapon, I would simply use RPC's to change the visuals and other components?

[fringe imp]

kinda yeah. Controller should be child of player though.

just with visual hidden

[ocean wadi]

Wouldn't we run into the same problem of nested network objects though if controller is a child of player and both of which are network objects (since my player is spawned in and not a scene object)?

[sharp axle]

Weapon controller wouldn't need to be a network object, just a network behavior. If the weapon is already attached to the player prefab, it doesn't need to be a network object either. Any child behaviours take the parent network object as their own.

If this is an object that is picked up and dropped, then if would suggest using rigidbody physics joints to attach them to players.

[tame slate]

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

I believe it's also built in that you can use a struct of primitive types to group things

[sweet siren]

I've seen people talking about host migration for NGO but I cant seem to find it on the docs or anywhere (I'm only seeing peoples' custom made host migration solutions). Can I get a link please?

Also any talk about experience with host migration would be awesome with stuff like how seamless the transition is or if there's any difficulties

[sharp axle]

The only built in Host Migration is through Distributed authority

[sweet siren]

Oh right...

Thanks for the link though lol. I guess it's just not quite what I need

[fleet ice]

hey guys in debug code ends in yield return www.SendWebRequest(); and i am not getting any debug log after this the payload i am getting is working on postman though.

this is where i am calling coroutine

[knotty harness]

has anyone managed to run the NGO+Multiplayer Widgets sample on a WebGL build with Relay? It's basically the most minimal test of NGO with Sessions (Lobby) running.

I'm trying in Unity 6, and a weird aspect is that it technically works as long as I create the session in the Editor and join it with the build (even if the "Joining Session..." log is never followed by the "Joined Session: <id>" log). I can move one player in each instance.

Buuut, I would need for the Create Session button to work in the build as well. There is no error to speak of, it just never ends Joining appropriately, so it never gives a Join Code to copy.

Otherwise, affirmation from anyone that has managed to run the Sessions with WebGL Relay in any of their projects would be nice to see, as I have not found any sample online that gives me any reassurance :/ .

[sharp axle]

I've run it with Distributed Authority and Webgl.

[knotty harness]

nice! that needs a dedicated server however, I'm aiming to have some "serverless" games running with Relay.

My suspicion right now is that the async await that the template uses on the EnterSession function just never finishes on browsers. are you yourself using the SessionManager.cs that comes with the template or you tweaked it?

alright, I confirmed that suspicion with a minimalistic test that I saw on this thread:

https://discussions.unity.com/t/async-await-and-webgl-builds/665972/70

Task and await just does not work on browser :/. the issue is a Unity bug and does not have to do with Networking so I'll stop asking in this channel. Thank you for the quick reply @sharp axle !

[sharp axle]

Distributed Authority has no servers actually. Just the DA servers similar to Relay

[knotty harness]

oh really? then I completely misunderstood Distributed Authority, I must look into it more, thank you!

@sharp axle do you per chance have any Task with await on your code and it's working on the build?

The Distributed Authority Quick Start guide also has one of those (in CreateOrJoinSessionAsync).

https://docs-multiplayer.unity3d.com/netcode/current/learn/distributed-authority-quick-start/

[sharp axle]

I didn't change any code. I set the connection type in the Widget Configuration asset. Check WebGL in the Unity Transport

oh for DA, I did have to manually change the transport to Distributed Authority Transport

[knotty harness]

ok thank you I will test doing that and see

[knotty harness]

cool! its nice to see I can choose DA and it gets to the same point of functionality but I'm seeing the same exact issue.

However if it works for you without changing any code then maybe it has to do with my browsers in particular or some setting, and I don't need to change the Tasks code.

[white meadow]

any example for project structure and networking? I mean I have offline game, wanna change it to multiplayer + add gamemode mechanism (timers, points). it's kinda fps, I wanna make it hosted by player

[sharp axle]

For NGO, you can check out the Bitesize samples Or Boss Room if you want to see a larger architecture

[tawdry night]

hey people just a small question how do i make it a object is invisable for all players when something happens?

[tame slate]

Lots of options. NetworkVariable to keep track of whether it is visible or not, RPC to toggle off any visual elements of the object, or Object Visibility

[tawdry night]

i want it like if i turned it on or off in hieracy

[tame slate]

The first two options I explained would be able to achieve that.

[tawdry night]

thx it workedd

[sweet siren]

Is there a way to put NGO in some sort of stasis? When the host disconnects I don't want NGO to do anything about it unless I tell it to

The idea is I want the person behind the host to host a server but since absolutely nothing is gonna change I wanted them to host with an identical scene and then others can join but I guess it wont be as simple as that

If I cant find a way I guess I'll just make my own stuff with LiteNetLib or something. Having to pause the flow because one person left is annoying and really ruins immersion. With LiteNetLib I can probably just treat the next host as the host and that's it

[tame slate]

You’re basically describing the need for a dedicated server. Host migration isn’t as simple as “treating the next host as the host and that’s it” in any networking solution.

[sweet siren]

I mean it seems like it would be so long as your codebase is versatile enough but what I'm describing would probably require a direct connection between all players

I was thinking the host was the only one clients would listen to and so the clients could switch who the host was relatively easily so long as the new host actually acts like a host

GTA pulls off something similar afaik but it's also why they had huge issues with security

[sharp axle]

When the host disconnects, the network ends. Same as if a dedicated server crashed. You could have all network objects be invisible ghosts that puppet around local game objects, that way a network object despawning will not effect the local objects

[tame slate]

Unless you were to freeze the network and every client's game world, have the host send all critical info to the next host and then allow the host to disconnect when that's done - it is not as a simple as a "switch". And that is not a realistic solution to rely on since a host disconnect will often be someone closing the application or crashing.

When a host disconnect occurs you are asking all of the remaining clients to cobble together and agree upon what the state of the network and game should be. This is not simple as at any given moment in time, clients x, y and z will all have slightly different network and game states.

I would explore using Distributed Authority if this is that critical to your game.

[sweet siren]

What if there isn't any critical info? It's meant to be p2p so my plan was all clients had a list of all players in the session ordered from first to join to last and whenever the host was unresponsive or something went wrong they switched to the next person in line

[tame slate]

That's entirely possible if you don't care about the other clients who are not the host rejoining in a slightly different game state than they were before the disconnect.

That being said, that's still going to require a good amount of work to implement.

[tame slate]

so IMO you'd be better of exploring something like DA or just accepting the fact that if it's casual p2p, that host disconnects just happen sometimes.

[sweet siren]

Distributed authority isn't quite what I want from what I understand but I guess yeah I might have to accept host disconnects sometimes. Unfortunately I'm not old enough to have a job yet so I cant really support dedicated servers or distributed authority money-wise so p2p with lobby has been my go-to for a bit

As annoying as it is to have abrupt host disconnects friend groups are the target so my options are probably let people host their own dedicated servers outside of the game or the friend group will probably collectively agree on a time to get off the game so it's probably less disruptive than I'm thinking

[tame slate]

Distributed Authority's free tier just like Relay's is extremely generous. You'd have to be looking at 100s of daily players before paying a cent.

and unless I'm missing something about your game and setup, it achieves pretty much exactly what you're wanting.

[sweet siren]

Yeah sorry I skimmed over distributed authority last time but I just gave it a thorough read and it does do pretty much what I want

I'll look into it I suppose. As counter-intuitive as it is I've always opted in for safety when it came to subscription based services like DA or Unity's other services despite the fact I really doubt I'll be reaching 100s of players. Maybe it's time to just use common sense and go for it

[fringe imp]

morning! I currently use relay with join code to join two players, im looking to be able to start game, click 1v1 quick join, and anyone else who clicks that gets matched.

Do i need to look into lobby stuff for this or can it be simpler?

[sharp axle]

It doesn't get much easier than with Multiplayer SDK Quick Join

[fringe imp]

Sorry for the premature question, havent had my coffe yet. Found this link right after i sent lol. Thanks man!

[severe spear]

hi, im using a docker container to host a linux server build of my game using nfgo and unity transport

for some reason, i can only connect with web sockets enabled

if web sockets arent enabled on unity transport then it just doesnt connect

however, if i use the windows server build outside of docker, it does work

ive tried every combination of ip and docker network i can think of

tcp connections pass through when i test with powershell

so ive sorta ruled out docker as the source of the problem

[white meadow]

which lib is most low cost(where 1 player is host and others just join lobby and play) + quick game option to just join random to lobby and start when there is X players?

[fringe imp]

GetNetworkObject(OwnerClientId);

is this right? Or is netowrkid different from client id

[sharp axle]

Its a not Library you are looking for but a Service. Epic Online Services are free to use and Steam P2P just requires the $100 developer fee. The Unity Relay and Lobby services have a very generous free tier that indie devs are unlikely to go beyond.

[sharp axle]

Sounds like you want to use NetworkObjectReference

[fringe imp]

woah this is different but cool, so i can passthrough players on here. Thanks

More so i was just wondering if the (netowrkid) in the function " GetNetworkObject(networkid) " == client id?

like if i said

Playerhealth health = Getnetworkobject(ownerclientid).getcomponent<PlayerHealth>();```
Is that correctly getting the client id or is networkid i seperate thing?

[sharp axle]

those are different. a client can own multiple network objects. If you are trying to get the Player Object then this section is what you want

[fringe imp]

ahh ok thx!

[knotty harness]

for anyone that finds themselves in my situation in the future, where Creating a Session does not return a code, or Threading tasks in general don't return a callback in a WebGL build, the way I got it solved for myself was just by installing this package from git, changing no code otherwise:

https://github.com/RageAgainstThePixel/com.utilities.async

If that's not enough for your issue, you might want to instead try this other one (altho for me in Unity 6, I could never make the WebGL build work with it):
https://github.com/VolodymyrBS/WebGLThreadingPatcher

[maiden saffron]

I just discovered this myself and came here looking for confirmation. Have Unity acknowledged that addressable do not work with NetCode and have a timeline when they will support? I cannot express how frustrated I am with Unity as literally any other multiplayer tool works with Addressables. Please tell me I am wrong and all I have to do is x or y.

[sharp axle]

Addressables work just not loading scenes through addressables. There is a PR on the Netcode GitHub that seems to address this but I've not tested it

[maiden saffron]

Would you be able to link me to that PR?

https://github.com/Unity-Technologies/com.unity.netcode.gameobjects/pull/3040

Found it

I am not overly familier with this side of Unity. Does this mean it is being worked on or is something I can try now?

[sharp axle]

NGO is open source so anyone can make contributions like this user did.

[maiden saffron]

Does this mean we are waiting for a review before we can try?

[sharp axle]

You can pull it yourself and merge it. Those reviews are to merge it with the main branch for official release

[maiden saffron]

Thank you

[sharp axle]

Obviously make a backup before making any major changes

[ocean wadi]

I had a question regarding ownership. Would I want each respective player to own the weapons they pick up? I was just wondering what the common industry standard is when it comes to handling object ownership. (Planning on making my game a casual game so I don't really care too much about cheating)

[sharp axle]

Really depends on what code you have running on the weapons.

[ocean wadi]

The code I have on the weapons control most of the weapons functions like cooldown/combo management, detecting overlapping colliders, applying damage.

[sharp axle]

There are lots of ways to handle that. If you are applying damage on collision, then it doesn't have to be a network object at all. The collision logic can be on the player and it can grab the damage information from the weapon.

[scenic trellis]

Hey guys Im kind of new to unity and Im trying to figure out some netcode stuff. Do any of you know how IsServer could come back as false after running NetworkManager.Singleton.StartHost()

[sharp axle]

Depends on when you are checking it. That value doesn't get set until after OnNetworkSpawn() is called

[scenic trellis]

Seriously? shoo did not know that

What I'm trying to do currently involves, calling startHost() and switching to a different scene containing network objects. But these objects OnNetworkSpawn() events are not being called. Am I missing something here?

[sharp axle]

Make sure you are using Network Manager Scene Manager

idea is firstly selecting a unit, then clicking on a tile to create a temporary unit image, then if player clicks on that image, unit goes there
but the thing is, when clients click to units, nothing happens
it only works on the host
i am using unity netcode and unity transport

[wide girder]

Do you actually execute this code on the client?

[oblique birch]

well, i figured out now

i started client from unity editor, not host like i usually do

and i got

Heya! I’m making my “copy” of CS:GO in Unity(2022 LTS), but can’t decide what Networking solution should I use. Can someone tell me what’ll be better to use? The game will have Matchmaking, Ranks, Lobbys and etc.
Currently I’m thinking of using FishNet with Steam.

Any of them can handle Team Shooters. It just depends on how much work you want to put into making a client prediction system for competitive multiplayer.
Most services like Matchmaking, Leaderboards, and Lobbies are also library agnostic and mainly come down to price.

I have this code, it is meant to make the movements and notify it to all clients. but it only works on client, other clients cannot see the changes

i got stucked really bad

need a hand

[oblique birch]

solved it nvm

Hello! I'm using Photon Fusion 2 and i'm having trouble getting VR Synchronisation to work.
I have a head object, and 2 hand objects, being driven by Tracked Pose Drivers, and XRControllers, then synchronized by NetworkTransforms, but for some reason only the Host is able to move their objects, while the clients can't move them at all.
Could it be that the NetworkTransform does not respect the input authority, and only the StateAuthority?? If so, how would i go about changing that behavior?

Hi, was wondering a good tutorial vid to start for making a multiplayer game in unity 6?

i plan on making a turn-based tactics online game with a handful of friends of mine so I imagine netcode requirements will be minimal

[jade glacier]

VR stuff is very specific, you might want to join the Photon discord

[sand talon]

They gate the photon discord behind a paywall

:(

[jade glacier]

State vs Input authority is going to be very specific to Host vs Shared mode

[jade glacier]

Not the public one

I am one of the original devs of Fusion btw, and I started the discord servers for Photon

So I am not making that up LOL

[sand talon]

Oh!? Cool! :D

[jade glacier]

Photon has two discord servers, public and circle

[sand talon]

Honor to talk!

[sand talon]

Is there a source i could find the circle one?

[jade glacier]

Circle is paid, the public is open to anyone though

[sand talon]

Ah! I see!

[jade glacier]

It might require a photon login to exist to validate you as a user is all

[sand talon]

So the one linked in the webpage is the circle one?

[jade glacier]

But that is free, just may need to have an account on the website

[sand talon]

Gotcha!

[jade glacier]

Not sure, I don't work for Photon now, but I would expect the link to the discord to be for the public

[sand talon]

Loading into it. Great

[jade glacier]

https://forum.photonengine.com/discussion/9898/is-there-an-official-unofficial-photon-discord-server-around you ended up with that following this link?

@vagrant garden not sure who to ping, but are there any obstacles currently involved in people joining the public discord?

[vagrant garden]

that looks like a discord problem and not a photon one

I'd just retry

Link to join the Photon discord is in the pinned messages here btw.

👍

You can use Netcode for Gameobjects or if it's asynchronous multiplayer then you can use Cloud Code or other serverless architecturs.

[white meadow]

anyone got any tutorial/examples of how to use [EOS] EpicOnlineServices in unity? I mean to create lobby and transport way?

[weak ember]

gotcha, thanks

[weak ember]

question and sorry if this sounds pretentious, is there a way of a free server for unity games with a small player count (like at most 5)?

[tame slate]

Relay is not a dedicated server but is a popular choice due to it's simplicity to set up and its generous free tier.

Hi, so I was actually planning on switching to fishnet from NGO. I was just wondering what some peoples opinions were on it who have worked with it. Also I was wondering before making the swap, if anyone knew the licensing around it. Is it okay to use for a game that I am planning on publishing on steam, I know that the licensing around open source code programs can be tricky at times.

[abstract copper]

it has similar features to many other networking solutions, but the main difference is that it has support out of the box for client prediction if you have a server authoritative game, and, in my opinion, more quality of life features. Also, it wouldn't be too useful if you couldn't publish your game with it! It is fine to use both the free or pro versions for commercial projects. Everything third party library it uses has the MIT license, and it itself is free to use / modify / redistribute (as long as you don't have the paid version, obviously you can't distribute that) https://github.com/FirstGearGames/FishNet/blob/main/THIRD PARTY NOTICE.md

I think it is one of the better options for real-time games if you don't plan on writing your networking with something like LiteNetLib

although if you are switching from NGO just because the networking gets convoluted, that is not something you can escape from with most of the Unity-specific networking frameworks (at least all the ones I have tried in the past). They will all have the same issues (one-size-fits-all style) since they can't cater to your specific game

[blissful jay]

client prediction of fishnet does not even work, it's buggy and jittery af

fishnet is not MIT licensed too, you can't redistribute it, it's not even legally clear if you can modify it at all

[blissful jay]

NGO supports host migration

which is very useful for coop or indie games

fishnet does not, neither mirror

[blissful jay]

We have a very negative opinion about fishnet. It claims to be stable when it's very buggy. The creator is banned in here for promotion fraud .

fishnet is not open source too
