So if an avatar shoots another avatar, you need to get their owners from their PhotonView.

#

Have you done the Getting Started tutorial?

lunar plinth Oct 11, 2020, 5:22 PM

#

not yet

jade glacier Oct 11, 2020, 5:22 PM

#

How are you trying to learn then?

lunar plinth Oct 11, 2020, 5:23 PM

#

i'm not done with it. I'm still on it

#

i mean i read a lot about it

jade glacier Oct 11, 2020, 5:27 PM

#

Can't really help you much until you get through it and understand the basics. Otherwise you are just asking people here to walk you through it.

weak plinth Oct 11, 2020, 6:42 PM

#

ok so i have this problem i want it so it will show an arrow above the local players gameobject and this is my script and i dont get why it doesnt work: ```public class Instantiate : MonoBehaviour
{
public GameObject arrow;
private void Awake()
{
if (PhotonNetwork.LocalPlayer.IsLocal)
{
arrow.SetActive(true);
}

    if (PhotonNetwork.LocalPlayer.IsLocal)
    {
        arrow.SetActive(false);
    }

    PhotonNetwork.Instantiate("PLayer1", new Vector2(Random.Range(-12.84f, 13.2f), 4.9f), Quaternion.identity);
}

}```

jade glacier Oct 11, 2020, 6:47 PM

#

LocalPlayer.IsLocal will always be true by definition no?

weak plinth Oct 11, 2020, 7:05 PM

#

ow

#

any idea how i would do this otherwise?

jade glacier Oct 11, 2020, 7:07 PM

#

Just hide an arrow graphic based on IsMine

weak plinth Oct 11, 2020, 7:07 PM

#

o

#

w

#

so

#

something like this? using System.Collections;

using UnityEngine;
using Photon.Pun;
using Photon.Realtime;

public class Instantiate : MonoBehaviourPunCallbacks
{
    public GameObject arrow;
    private void Awake()
    {

        if (photonView.IsMine)
        {
            arrow.SetActive(true);
        }

        else
        {
            arrow.SetActive(false);
        }

        PhotonNetwork.Instantiate("PLayer1", new Vector2(Random.Range(-12.84f, 13.2f), 4.9f), Quaternion.identity);
    }
}```

#

cuz that gives me this error NullReferenceException: Object reference not set to an instance of an object Instantiate.Awake () (at Assets/Photon/PhotonUnityNetworking/Resources/Instantiate.cs:13)

prime beacon Oct 11, 2020, 7:42 PM

#

Umm try moving your code to Start()

#

@weak plinth

weak plinth Oct 11, 2020, 7:43 PM

#

k

#

nope doesnt fix it

#

o

#

i might have fixed it

#

nvm

#

now it doesnt work anymore

#

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

public class Instantiate : MonoBehaviourPunCallbacks
{
    public GameObject arrow;
    private PhotonView photonView;
    public GameObject Player;

    private void Start()
    {
        
    }
    private void Awake()
    {
        photonView = Player.GetComponent<PhotonView>();
        if (photonView.IsMine)
        {
            arrow.SetActive(true);
        }

        else
        {
            arrow.SetActive(false);
        }

        PhotonNetwork.Instantiate("PLayer1", new Vector2(Random.Range(-12.84f, 13.2f), 4.9f), Quaternion.identity);
    }
}```

is photon a suitable environment for persistent player shops? Thinking of using playfab to hold players inventories and currency, then transfer between the two but the only google search relevant comes up with an old post from 2014 saying photon being peer-to-peer is not suitable for this, I'm assuming they didn't take playfab into account and were referring to a photon-only solution.

tldr photon + playfab = persistent player-to-player shops ie auctions so on?

#

I'm sure it's possible just making sure photon being peer to peer won't be an issue in this quest

jade glacier Oct 11, 2020, 9:42 PM

#

Photon products are for the realtime aspects of gaming. Persistent stuff you would use something like Playfab.

abstract flax Oct 12, 2020, 2:02 AM

We are trying to help our friend with this small indie game. He has a single camera 4 person game. Currently local co-op. He wants to add networked multiplayer. He suggested we look into Photon. I have successfully converted his code so we can render and move around networked players. We are struggling to figure out how we can have local co-op players mixed in with networked players. eg: 2 local players + invite a steam friend who has their own 2 local players. Is this even possible? Seems like we'd need to keep track of locally joined players and manage the logic of if the room is "full" on our own? Does anyone know of a server solution that would handle this use case better?

gleaming prawn Oct 12, 2020, 8:25 AM

#

Is this even possible?
Yes, but you need to code it yourself, assuming that by "photon" you mean PUN (photon unity networking, one of the products in the photon family).

#

Does anyone know of a server solution that would handle this use case better?
Yes, photon quantum has this as a basic feature (multiple local players)

Hello! Is there a good resource to make a server inside unity that is fast? I tried TCPSockets but it's very slow for player movement. The player movement jitters

shut yarrow Oct 12, 2020, 2:25 PM

#

Use UDP

silver steeple Oct 12, 2020, 2:27 PM

#

Also if it's jittering, you should interpolate between positions

ocean abyss Oct 12, 2020, 2:27 PM

#

Should TCPSockets be jittering in a local network?

silver steeple Oct 12, 2020, 2:27 PM

#

no

ocean abyss Oct 12, 2020, 2:29 PM

#

I'm doing something bad then 😅

silver steeple Oct 12, 2020, 2:29 PM

#

are you interpolating between positions?

ocean abyss Oct 12, 2020, 2:29 PM

#

No interpolation at the moment

silver steeple Oct 12, 2020, 2:29 PM

#

that's ya problem. All games ever do that. Doesn't matter UDP vs TCP

shut yarrow Oct 12, 2020, 2:30 PM

#

True but TCP is a bad choice for realtime movement

silver steeple Oct 12, 2020, 2:31 PM

#

If it's always going to be local then no harm no foul. But yeah agreed.

fair cosmos Oct 12, 2020, 2:47 PM

#

hey guys i want to sync skins between players

#

any approach

#

for syncing of weapons and teams i use enums

silver steeple Oct 12, 2020, 2:48 PM

#

like, UV maps?

fair cosmos Oct 12, 2020, 2:48 PM

#

but skins are a lot

#

@silver steeple no

#

sprite

silver steeple Oct 12, 2020, 2:49 PM

#

Are you modifying it like, every frarme or something?

fair cosmos Oct 12, 2020, 2:49 PM

#

nope,

#

i am just asking how to sync stuff like that which is in large amount not in limited like teams, squads or weapons

silver steeple Oct 12, 2020, 2:50 PM

#

Just trying to understand your situation, and why you can't just do what you've been doing with something like weapons and enum solution

fair cosmos Oct 12, 2020, 2:50 PM

#

nope

#

i have to do that

#

public enum Skin{ green, blue, sooo.. on }

silver steeple Oct 12, 2020, 2:51 PM

#

oh. So you're already using an enum for skins?

fair cosmos Oct 12, 2020, 2:52 PM

#

noPe i am not goin to

#

i just wanted to know is there any other approach to sync stuff like skins which is in large amount

silver steeple Oct 12, 2020, 2:53 PM

#

Enums.. IDs... etc

fair cosmos Oct 12, 2020, 2:54 PM

#

@silver steeple so how to do it with ids

#

ids can conflict!!!

silver steeple Oct 12, 2020, 2:55 PM

#

if you let them conflict sure. There's plenty of ways to prevent that. Or the internet as we know it would not exist.

fair cosmos Oct 12, 2020, 2:56 PM

#

@silver steeple so whats the process of it

gleaming prawn Oct 12, 2020, 2:57 PM

#

IDs should not conflixt

#

if it's your game and you decided for the game assets database I mean

silver steeple Oct 12, 2020, 2:59 PM

#

@fair cosmos depends on your situation. It's hard to understand the context and why you're having trouble with anything. Would recomend looking into how to prevent IDs from conflicting in whatever situation you're in.

gleaming prawn Oct 12, 2020, 2:59 PM

#

In all game clients the same skins would have the same IDs/Indexes respectively, etc

#

It's your game data, etc

#

Say you store your skins as an Array in a scriptable object or any other mean... Then just pass the index of the chosen skin, etc

silver steeple Oct 12, 2020, 3:00 PM

#

There's no excuse for why they would conflict tho. Things like youtube, a massively distributed asyncrounous realtime system dealing with billions of requests still maintain unique video IDs

gleaming prawn Oct 12, 2020, 3:00 PM

#

That's it

#

If you are using a player profile database like Playfab, the unique IDs for each individual item/skin would be generated there, etc

#

So there's no conflict

fair cosmos Oct 12, 2020, 3:01 PM

#

@gleaming prawn thnx

dusk cargo Oct 12, 2020, 10:19 PM

On Photon when I pass a variable via RPC, does it use the local avatars version of that variable or does it pass the one from the networked player

#

If that makes any sense

copper wadi Oct 12, 2020, 11:02 PM

#

GameObject go = GameObject.FindGameObjectsWithTag("Player").ToList().Find(g => g.GetPhotonView().owner.ID == switcher.ID);
            PlayerGameplay pg = go.GetComponent<PlayerGameplay>();

else if (Weapons[weapon].IsSecondary)
            {
                if (pg.m_Camera.enabled)
                {
                    pg.Weapons[SelectedWeaponIndex].gameObject.SetActive(false);
                    pg.Weapons[weapon].gameObject.SetActive(true);
                    pg.Weapons[weapon].gameObject.GetComponent<OnAnimationWeapon>().PlayerGameplay = this;
                    pg.FPSAnimator = Weapons[weapon].gameObject.GetComponent<Animator>();
                }

                pg.isReloading = false;

                pg.SoldierAnimator.runtimeAnimatorController = SoldierAnimatorSelection[1];

                pg.WeaponHolder[SelectedWeaponIndex].SetActive(false);
                pg.WeaponHolder[weapon].SetActive(true);
            }```

this is a part of code i use for letting the players switch weapons through the network, it's sent with a photon rpc, but i cant get it to work and i have no idea why

i basically copied my script from the not networked weapon switch and i call the networked weapon switch from the not networked weapon switch

jade glacier Oct 13, 2020, 12:37 AM

#

The values you pass to Invoke arrives on other clients as the argument values for that RPC.

Being straight:

if you come up with a few directly technical questions, people may answer
if you want someone to go step by step and teach+write the code for you, this means hiring/paying someone for their time spent (possible, but not sure this is what you meant).
you can always go for youtube and blog tutorials: http://letmegooglethat.com/?q=pun2+tutorial

dusk cargo Oct 13, 2020, 10:13 AM

#

📎 unknown.png

#

Hey can anyone let me know if this is wrong

#

Is it possible for the local player to send variables like this via RPC's?

gleaming prawn Oct 13, 2020, 10:21 AM

#

what is ScriptablePose?

#

Is it a Scriptable Object?

#

If yes, NO, not possible like that

#

You should send something like:

the string name of the scriptable object, so it can be loaded from the receiving RPC (slower)
an int pointing to the array index of that scriptable object in an array you define in a ListOfPoses main scriptable object that ALL game clients have (cleaner and faster)

#

It's NEVER possible (or sometimes not advisable) to send these as part of RPC params:

game object (not possible, send a way to find the same object)
scriptable object (same as above)
textures, audio, assets in general (too much data, does not make sense - do as above and send an index/name)

jade glacier Oct 13, 2020, 10:39 AM

#

Whatever scriptablepose is, you will need to define your own serialization and deserialization handling for it. You can't pass arbitrary objects to photon for serialization. Only supported types automatically serialize.

dusk cargo Oct 13, 2020, 10:44 AM

#

That you for detailed responses guys. I ended up taking the string and send that in the RPC then using Resources.Load on the networked avatar

#

@gleaming prawn I don't want to have to store all different poses at runtime, on an in-scene object but I agree that way if they were in the scene would be much better

#

@jade glacier Thanks for breaking that down for me. I've only been using Photon for week so still getting the jist of how everything works. Doing it for VR as well poses quite a few extra challenges

#

Would either of you have any advice on how to handle the disconnect between held objects and hands on networked players. Both have different PhotonViews so I can set the streams in a way to pass all the data in synce.

Edit: I've just realised that while you can't modify observed comps, you can disable and enable them which opens up a lot of possibilties

lunar plinth Oct 13, 2020, 12:32 PM

#

i can't understand why is this saying that object reference is not set to an instance of an object

#

Debug.Log(photonView.Owner.ActorNumber);

lunar plinth Oct 13, 2020, 12:55 PM

#

got it

lunar plinth Oct 13, 2020, 1:12 PM

#

i have this simple script to show deaths of a player PlayerScoreboards[i].transform.GetChild(1).GetComponent<Text>().text = "Deaths: " + playerScoreDeaths[PhotonNetwork.PlayerList[i].ActorNumber - 1];

#

but if second player joins

#

i get this IndexOutOfRangeException: Index was outside the bounds of the array.

#

public int[] playerScoreDeaths = new int[6];

#

it seems that it gives an error when array is more then 0

#

localPlayer.transform.GetChild(1).GetComponent<PhotonView>().Owner.ActorNumber this gives the same error

#

playerScore[localPlayer.transform.GetChild(1).GetComponent<PhotonView>().Owner.ActorNumber] = 0;

#

even this

lunar plinth Oct 13, 2020, 1:51 PM

#

anyone?

gleaming prawn Oct 13, 2020, 1:52 PM

#

maybe you should join Photon's DIscord

lunar plinth Oct 13, 2020, 1:54 PM

#

this doesn't seem to be a thing

#

is there a way to not use .ActorNumber but still get player id.

#

because that thing seems to be breaking everything

#

ok i did a little bit more tweaking and...

#

        playerScore[playerId] = 0;```

#

only second line gets an error

#

this one playerScore[playerId] = 0;

jade glacier Oct 13, 2020, 3:31 PM

#

Is PlayerScore a dictionary or an array?

#

This looks like a C# understanding problem at a glance, not actually a networking issue.

sterile ore Oct 13, 2020, 4:35 PM

mirror only updates movment unitl other player joins the server then it leaves the player standnig even if i move on the other client ill be still

does anyone know of a good networking library for unity 2020.1? mirror networking doesn't work for me and has errors upon building, photon is expensive to use, and UNET is decprecated and i cant even find it anymore in the actual code

#

telepathy is not resolved in mirror networking so i cant use that :/

📎 unknown.png

jade glacier Oct 13, 2020, 8:25 PM

#

Mirror should work.
And Pun2 only costs money if your game is successful.
Unet and Mirror both will require hosting or nat punch, but do have a Unity exe for a server. Unet is deprecated, but it would give you about the same set of difficulties as Mirror/MLAPI.

Your requirements for networking seem a bit steep?

#

Just hit the Mirror discord for help resolving that transport issue.

white wedge Oct 13, 2020, 8:26 PM

#

i just want a working library that doesnt cost because i want to host it myself

#

does mirror work in 2020.1?

#

it says it requires 2018 on their docs so maybe thats the problem?

#

alright well i might have to join yet another discord server just for this :/

jade glacier Oct 13, 2020, 8:27 PM

#

No idea, hit up their discord and see

#

If you are losing patience with networking just picking a library, I have to warn you that the actual development experience is likely not going to be your bag.

#

Networking games is the most difficult part of game dev.

#

Expect lots of frustration and failure along the way.

There is no silver bullet solution however so you need to pick something and get some experience along the way

@white wedge mlapi works in 2020.1

somber drum Oct 13, 2020, 11:52 PM

#

hm so,

DefaultPool failed to load "APrefabInResources". Make sure it's in a "Resources" folder. Or use a custom IPunPrefabPool.

#

this is using a well known kit, which works all until I close out of unity for the night and restart, then it throws the above.

#

"ask the dev for help" he's pretty inactive, and I'd like to solve this myself if possible

#

(photon)

#

oddly enough it was to do with my scene, which makes sense if it's running at a certain- I don't even know. Whatever it works now lol.

jade glacier Oct 14, 2020, 12:09 AM

#

"APrefabInResources" looks an awful lot like a placeholder

#

like "InsertNameOfYourPrefabHere"

nocturne current Oct 14, 2020, 5:11 AM

#

Does anyone know if services like Multiplay or AWS Gamelift provide their own networking library, or are they purely hosting platforms, and a library like MLAPI or Mirror is still needed?

somber drum Oct 14, 2020, 6:30 AM

#

@jade glacier lol yes, but unless me renaming it for the sake of clarify effects it

#

to be clear it is assigned and it is an actual prefab,

#

original name was "AISoldier" if that helps

#

which it doesn't, so anyway.. that's my life

#

@nocturne current From what I understand no they will not providing a network library for your game they are just hosting what you've already made

#

I'm not sure if that's the case for lumberyard with what I can only assume would be a tight integration but for unity it's not the case

#

MLAPI is a great choice, though mirror has a far larger community / examples so on

nocturne current Oct 14, 2020, 6:34 AM

#

Alright thanks! That is was I was assuming and hoping for so that there is more flexibility when it comes time to actually work on hosting.

#

I've been stuck between MLAPI and Mirror, so I haven't made a decision yet. Are you aware of any "success stories" for games using MLAPI?

somber drum Oct 14, 2020, 6:41 AM

#

good comparison here;
https://mlapi.network/features/
also found this, which uses mlapi as well as the steam transport
https://www.youtube.com/watch?v=2Mz-j7CLhac
@nocturne current

#

"success" is relative but I would say mirror definitely has the lead in that

sacred grail Oct 14, 2020, 6:41 AM

#

from looking at Mirror and MLAPI the advantage for the latter seems to be its code seems very concise, clean and performant. It also has some advanced features, in the client prediction department.

#

MLAPI looks like it will be a bit more work to get started, but for more advanced projects will likely save time I suspect.

somber drum Oct 14, 2020, 6:42 AM

#

If you know what you're doing definitely go with MLAPI, just starting out I'd stick with mirror

#

https://mirror-networking.com/showcase/

#

some pretty decent names in mirrors book, using it myself currently so I'm a bit biased lol. Though MLAPI was my first choice, community support stood out

sacred grail Oct 14, 2020, 6:46 AM

for my project I am trying to decide if I should just go with the new netcode, since I am starting with 2020.2 or if I should use MLAPI.

Awesome! I'll take a look at comparisons and go from there. I'm starting to lean more towards MLAPI.

If you have the time and are willing to go through many code changes as DOTS comes out of preview, I would say go for it.

sacred grail Oct 14, 2020, 6:52 AM

#

Danmw3 ya same. But since my project time horizon is a couple years and I don't need dots for the majority of the game play, just the more complex work and I want to use havok physics it makes sense for me.

nocturne current Oct 14, 2020, 6:52 AM

#

My final straw was when something panicked, threw a invalid memory address exception, and managed to crash several other programs including my GPU drivers.

#

At that point I just didn't even want to know what other issues there might be.

sacred grail Oct 14, 2020, 6:54 AM

#

understood, I suspect dots will be pretty stable in 6-9 months. the recent changes have made the code quite a bit easier to use and I suspect that will continue.

I sure hope so with Unity's change of pace and focusing more on ironing out all of the "half-baked" features.

how would i select a random player in the server?

sterile ore Oct 14, 2020, 11:30 AM

#

@weak plinth give each player their own number or put them in array then choose one

#

how to make so that rach client has an invididual camera

weak plinth Oct 14, 2020, 11:40 AM

#

give each player their own number or put them in array then choose one
How? When I use an array currently it’s different for all clients

#

And how would I match the correct number with the corresponding gamepbject

sterile ore Oct 14, 2020, 11:52 AM

#

wait do you use mirror*

#

@weak plinth

weak plinth Oct 14, 2020, 11:52 AM

Nah pun

sterile ore Oct 14, 2020, 11:53 AM

oof

#

then i cant help you

jade glacier Oct 14, 2020, 12:07 PM

#

@weak plinth unless you get into making server plugins, you would probably want to have the Master Client do what you are describing. It can "act" like the server as needed.

#

Have the master select a random actorID and RPC that to all others.

weak plinth Oct 14, 2020, 12:08 PM

#

ActorID?

Does Photon send RPC to only 1 room or all rooms?

jade glacier Oct 14, 2020, 1:46 PM

#

Players can only be in one room

grand skiff Oct 14, 2020, 1:47 PM

#

What do you mean

fallen frigate Oct 14, 2020, 1:47 PM

thats the thing i wanna learn ,exactly same

grand skiff Oct 14, 2020, 1:48 PM

i'm making a server matchlist and i want to get all rooms' data.

📎 unknown.png

#

any suggestion?

jade glacier Oct 14, 2020, 1:49 PM

#

I don't believe you can RPC outside of a room. If you are connected to the master server, that isn't something you can do.

fallen frigate Oct 14, 2020, 1:49 PM

#

i wanna learn it too , how can i learn this ? pls help me guys

grand skiff Oct 14, 2020, 1:49 PM

#

so is it impossible?

jade glacier Oct 14, 2020, 1:49 PM

#

You aren't in a room, so there are no other players

#

Matchmaking and being in a Game Room are very different.

fallen frigate Oct 14, 2020, 1:50 PM

please somebody help me with photon ,please i am really struggling from a week

grand skiff Oct 14, 2020, 1:51 PM

i got what do you mean, but so what should i do? Do you know anything that can help me?

jade glacier Oct 14, 2020, 1:51 PM

#

Have you completed the Getting Started tutorial? @fallen frigate

fallen frigate Oct 14, 2020, 1:52 PM

yeah i installed photon into my project ,already made an account in photon .com and know how to connect with master server

i have read that whole article

and kinda have idea how multiplayer works

#

rooms or lobby etc

#

but i don't understand how to use it in my unity project

grand skiff Oct 14, 2020, 1:54 PM

#

Is there a way to RPC to another room?

jade glacier Oct 14, 2020, 1:55 PM

#

I am not sure what to tell you. The point of the tutorial is to walk you through how to get a working networked project happening. @fallen frigate Be sure to DO the tutorial, not just skim it.

#

@grand skiff no

grand skiff Oct 14, 2020, 1:55 PM

#

😦

fallen frigate Oct 14, 2020, 1:56 PM

#

ok but i don't want to make my player randomly join room

grand skiff Oct 14, 2020, 1:56 PM

#

how can i get list of rooms in PHOTON?

jade glacier Oct 14, 2020, 1:56 PM

#

If you have a specific question, you can of course ask it @fallen frigate

fallen frigate Oct 14, 2020, 1:59 PM

#

3 days ago i followed some tutorial from youtube and i made my player radomy join or create a room from that ,in which i attached my launcher script with ui scene and after entering name of player it instantiate it in room after clicking join button

but i want something like among us ,in which we can create a room give a code to friends and they can join it so we can play together

shut yarrow Oct 14, 2020, 2:00 PM

#

You're trying to go too fast I think

#

First you have to know how to make a room

fallen frigate Oct 14, 2020, 2:01 PM

#

by creating a scene ?

shut yarrow Oct 14, 2020, 2:01 PM

#

I mean you need to know a little bit about how PUN works

fallen frigate Oct 14, 2020, 2:01 PM

#

yeah

#

thats why i wanna learn

#

not just wanna download some projects from github and use them

shut yarrow Oct 14, 2020, 2:02 PM

#

I haven't played among us so no idea how their code works, but I did something similar where you'd go to a URL and it would connect you to a photon room

fallen frigate Oct 14, 2020, 2:02 PM

#

yeah yeah something like that

shut yarrow Oct 14, 2020, 2:03 PM

#

Basically the one who created the room can create a URL and someone else can paste that URL in the game, the name of the room is then obtained through a http request and then you can join

fallen frigate Oct 14, 2020, 2:04 PM

#

yes

#

host can create and client can only join

shut yarrow Oct 14, 2020, 2:05 PM

#

That's not a photon question however, you'd have to know a little bit about web requests too and how to create a simple webserver to help with matters like this

fallen frigate Oct 14, 2020, 2:06 PM

#

yes i know it is pretty complex process without photon thats why i am using photon

shut yarrow Oct 14, 2020, 2:07 PM

#

Creating the room is as simple as calling PhotonNetwork.CreateRoom, then you (or rather the client who created the room) has to do a http post request, passing the roomname to a webserver which stores the room name and returns a web addres or some code that another client can then use to connect

fallen frigate Oct 14, 2020, 2:07 PM

#

like there is a demo asteroid scene in photon and i just wanna make something similar to it ,neat and simple

shut yarrow Oct 14, 2020, 2:08 PM

#

I think that's wiser to just try and do something simple like that first so you have an idea of how PUN works

fallen frigate Oct 14, 2020, 2:10 PM

#

yes i am aiming for very simple ,just to learn not even a actual project ,how it works ,how i can use but i passed 7 days without much progress bcz ,i only understand

how to install and integrate photon in your scene
how to connect with master server
and thats all with some theoretical stuff

#

i have even read all the documentation page of photon website

prime beacon Oct 14, 2020, 2:11 PM

#

so you want to create a room and pass room name to other clients right?

fallen frigate Oct 14, 2020, 2:11 PM

#

yes

prime beacon Oct 14, 2020, 2:12 PM

#

📎 unknown.png

#

then call PhotonNetwork.JoinRoom("roomname") on client

fallen frigate Oct 14, 2020, 2:13 PM

#

with room name right ?

prime beacon Oct 14, 2020, 2:14 PM

#

yeah

fallen frigate Oct 14, 2020, 2:15 PM

#

so first i have to make a empty gameobject with photonmanager script attached to it ,in which i will do that stuff and i can trigger any funtion in that script with button on click method right ?

prime beacon Oct 14, 2020, 2:21 PM

#

photonmanager?

fallen frigate Oct 14, 2020, 2:30 PM

#

script name @prime beacon and sorry here was a powercut thats why i took so long to respond

prime beacon Oct 14, 2020, 3:23 PM

#

yes

#

make sure you are connected to master before creating room

#

@fallen frigate

fallen frigate Oct 14, 2020, 3:26 PM

#

ok ,can i ask you if i face any problem @prime beacon ?

prime beacon Oct 14, 2020, 3:29 PM

#

well I don't use PUN actively just have general idea about it

#

but sure you can ask

jade glacier Oct 14, 2020, 3:40 PM

#

Always better to just post simple clear questions to the channel. Whoever knows the answer and is free will try to help.

sterile ore Oct 14, 2020, 4:31 PM

#

how to have each client have their own camera(camera is a child of a player) in mirror?

jade glacier Oct 14, 2020, 6:32 PM

#

Disable the camera on your player prefab based on NetworkIdentity.hasAuthority is the most simplistic way.

public struct Item

    public int amount;
    public Color32 color;
}

public class Player : NetworkBehaviour
{
    readonly SyncList<Item> inventory = new SyncList<Item>();

    public int coins = 100;

    [Command]
    public void CmdPurchase(string itemName)
    {
        if (coins > 10)
        {
            coins -= 10;
            Item item = new Item

                name = "Sword",
                amount = 3,
                color = new Color32(125, 125, 125, 255)
            };

            // during next synchronization,  all clients will see the item
            inventory.Add(item);
        }
    }
}

#

does anyone know why this would result in:
"Cannot create an instance of the abstract class or interface"?
at line:
🛑 readonly SyncList<Item> inventory = new SyncList<Item>();🛑

weak plinth Oct 15, 2020, 12:03 AM

#

Assuming mirror; SyncList<T> is an abstract class. You have to derive from it and implement yourself (unless using one of the prebuilt types:

   public class SyncListString : SyncList<string>
   {
       protected override void SerializeItem(NetworkWriter writer, string item) => writer.WriteString(item);
       protected override string DeserializeItem(NetworkReader reader) => reader.ReadString();
   }

#

here is how you'd use it for your struct - https://hatebin.com/lirpnzecsm

somber drum Oct 15, 2020, 1:23 AM

#

so my network behavior class is fine, I need this in addition to it

#

https://mirror-networking.com/docs/Articles/Guides/Sync/SyncLists.html

jade glacier Oct 15, 2020, 1:26 AM

#

What is your Item class?

somber drum Oct 15, 2020, 1:28 AM

#

probably not what it's supposed to be I would assume, given the example provided

jade glacier Oct 15, 2020, 1:28 AM

#

I mean, can you paste that class?

somber drum Oct 15, 2020, 1:30 AM

#

in my case item would be player, all I'm trying to do is sync a list of players
public class Player : NetworkBehaviourNonAlloc {

#

it's not something I can paste here no

#

the entire class

jade glacier Oct 15, 2020, 1:31 AM

#

You are trying to make a List of that and sync it?

somber drum Oct 15, 2020, 1:32 AM

#

a list of gameobjects that hold the player class, sync that as a list yep

jade glacier Oct 15, 2020, 1:32 AM

#

yeah, that is going to not end well.

somber drum Oct 15, 2020, 1:32 AM

#

I know how to offline, why not online with synclist?

jade glacier Oct 15, 2020, 1:32 AM

#

your class or struct I would expect needs to be restricted to primitives

somber drum Oct 15, 2020, 1:32 AM

#

whenever a client joins, if not added already add them to the list and sync- that seems simple

jade glacier Oct 15, 2020, 1:32 AM

#

a MonoB is a whole different animal.

#

The issue is you are asking Mirror to serialize a very complex object

somber drum Oct 15, 2020, 1:33 AM

#

would you recommend a more simple sync choice then?

#

maybe their id

#

but like eh.. I would like to access them more easily

jade glacier Oct 15, 2020, 1:33 AM

#

A value or a simple struct/class that only contains items you want synced

somber drum Oct 15, 2020, 1:34 AM

#

really I would just like their object

jade glacier Oct 15, 2020, 1:34 AM

#

If you try to sync a MonoB it will 1) Probably puke on that and just say no and 2) End up serializaing a bunch of garbage fields that have no business being serialized.

somber drum Oct 15, 2020, 1:34 AM

#

understood

#

synclist I take it is for very specific cases then, that makes sense

jade glacier Oct 15, 2020, 1:35 AM

#

If serialization were that easy, you could just RPC(MyScene) and be done with it... but obviously that can't be done.

somber drum Oct 15, 2020, 1:35 AM

#

haha right

#

my bad

lunar plinth Oct 15, 2020, 11:03 AM

#

i get this when trying to do this

📎 unity_error_transform.png

#

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

public class FragmentsCollision : MonoBehaviourPun
{
    public float damage;
    public int GrenadeOwner;
    void OnCollisionEnter2D(Collision2D collision)
    {
        photonView.RPC("DamagePlayer", RpcTarget.All, collision.transform);
    }

    [PunRPC]
    void DamagePlayer(Transform playerTransf)
    {
        Health hpScript = playerTransf.GetComponent<Health>();
        if (hpScript != null)
        {
            hpScript.damage(damage, GrenadeOwner);
        }
        Destroy(gameObject);
    }
}```

#

why can't i pass transform

#

i did it before

#

but this specific one doesn't want to work

high night Oct 15, 2020, 11:17 AM

#

@lunar plinth You probably can pass the pun network identity component

#

i think

#

i dont know the exact name of the component

#

i am talking about that one component you have on all networked objects, that enables you to do pun stuff

lunar plinth Oct 15, 2020, 11:19 AM

#

ah PhotonView

high night Oct 15, 2020, 11:19 AM

#

yeah i think

#

i think you will have to pass that in param

#

or maybe gameobject @lunar plinth, it could work as well
its been a while and i dont do networking this way

lunar plinth Oct 15, 2020, 11:23 AM

#

neither of those worked

#

i still don't understand RPC. I changed it to just a function and it works

#

can someone please explain what is an actual RPC use

#

i tried searching tutorials

#

but they don't explain why do i need it over funtion

#

documentation doesn't seem that clear also

jade glacier Oct 15, 2020, 11:38 AM

#

You can't pass transform to pun2 serialization.

lunar plinth Oct 15, 2020, 11:39 AM

#

what can i pass through it tho?

jade glacier Oct 15, 2020, 11:40 AM

#

Vector2, vector3, quaternions

lunar plinth Oct 15, 2020, 11:40 AM

#

so just numbers?

#

Received RPC "Explode" for viewID 0 but this PhotonView does not exist! Was remote PV. Remote called. By: #02 '643' Maybe GO was destroyed but RPC not cleaned up. what does that even mean

#

grenade has a photonView

#

and it's id is actually 0

jade glacier Oct 15, 2020, 11:56 AM

#

Pretty sure zero isn't a valid view Id, so not sure how you have one with that number.

lunar plinth Oct 15, 2020, 11:57 AM

#

ah i was instantiating it not by photonNetwork.instantiate

#

but there is a problem

#

if i instantiate inside RPC. There is 2 grenades appearing. One is the correct one that completely works. And another one just kinda sits there

#

i feel like it's not 2 but 1 per player

weak plinth Oct 15, 2020, 12:27 PM

#

for some reason PhotonNetwork.AutomaticallySyncScene isn't working, the only person that doesn't go into the new scene is the master client

#

Anyone know what’s going on?

jade glacier Oct 15, 2020, 12:34 PM

#

The master client should be where scene changes originate from no?

weak plinth Oct 15, 2020, 12:37 PM

#

i thought that would work but i still had issues

#

just tested it, the masterclient stays in the previous scebe

#

should i change levels in an rpc or a normal void using photon.loadlevel

#

update: even when its not in an rpc the master client doesnt go in the new level

jade glacier Oct 15, 2020, 12:56 PM

#

I don't really touch that part of Pun2 so I don't know what the correct or best practices are. But I would read the documentation on it and look at some of the sample scenes for guidance. @weak plinth

weak plinth Oct 15, 2020, 12:56 PM

#

okay

lunar plinth Oct 15, 2020, 12:57 PM

#

are RPCs like a static function?

prime beacon Oct 15, 2020, 12:57 PM

#

@weak plinth master client should load scene

#

if (PhotonNetwork.IsMasterClient)
{
   LoadGameScene();
}```

weak plinth Oct 15, 2020, 12:57 PM

#

oki

#

as well as the photon load?

jade glacier Oct 15, 2020, 12:58 PM

#

@lunar plinth You really need to complete the Pun2 basics tutorials and read the docs for some of this stuff.

lunar plinth Oct 15, 2020, 12:59 PM

#

i kinda rode through the documentation

#

and watched some basic tutorial series

prime beacon Oct 15, 2020, 12:59 PM

#

 if (PhotonNetwork.IsMasterClient)
        {
            PhotonNetwork.LoadLevel("Arena");
        }

#

also this -> PhotonNetwork.AutomaticallySyncScene = true;

jade glacier Oct 15, 2020, 1:00 PM

#

I can tell @lunar plinth

lunar plinth Oct 15, 2020, 1:00 PM

#

i skipped something. Little things.

#

~~i probably shouldn't have skipped~~

jade glacier Oct 15, 2020, 1:02 PM

#

Networking is VERY difficult. Don't kneecap yourself by trying to skip to the end.

#

You will end up stuck on simple things for weeks.

lunar plinth Oct 15, 2020, 1:05 PM

#

now when i think about it the only thing i skipped was raise event

#

but here is a question. Again i want to transfer a game object to the RPS. But how can i convert the game object into the number and then back? Is that even possible?

jade glacier Oct 15, 2020, 1:07 PM

#

The question is more vague than you think, but what you are describing cannot be done. You don't serialize "objects" and have them instantiate on the other end.

#

You instantiate objects using PhotonNetwork.Instantiate, and then you sync up values within those objects.

lunar plinth Oct 15, 2020, 1:08 PM

#

The reason why i need this is because i instantiate an object in the normal function via PhotonNetwork.Instantiate and then i want to parent it to the player

#

but i parent it via an rpc so it parents to the player on every pc

jade glacier Oct 15, 2020, 1:09 PM

#

you can serialize reparenting, though you will need to come up with a way of indexing the parent object so that all clients agree on its index.

lunar plinth Oct 15, 2020, 1:10 PM

#

o o f

#

well time to get stuck on this part for another 5 hours

#

wait if i make an RPC that will fire a normal function will it work?

jade glacier Oct 15, 2020, 1:18 PM

#

Or just read up on the docs and finish the tutorials so you aren't struggling so much 🙂

slate sable Oct 15, 2020, 1:39 PM

#

What is according to you guys the best and the most simple way to make a server which is can be joined from other ip's for a beginner?

shut yarrow Oct 15, 2020, 1:45 PM

#

There is no best nor there is any simple way

#

And although I understand why you are asking this question and this channel is supposed to be about networking, what have you done so far to find out what options there are that you could choose from?

#

Because if you want to make any type of multiplayer game, it's important to have a good idea of what requirements you have and what options in libraries you have, just telling you what is good in your case is impossible

jade glacier Oct 15, 2020, 1:48 PM

#

Do tutorials for Mirror and Pun2 at the very least first. Then decide on your game goals... THEN you might be able to start thinking about the right library choice.

#

Any answers you get to your question will look like a meaningless wall of jargon right now.

terse relic Oct 15, 2020, 1:58 PM

#

What type of game u making

#

Photon is simplest to learn but if u plan to launch a game then think of the best way to monetize it cuz photon will cost a bit. If u have cash on hand then I suggest buying a small dedicated server and using mirror. Again monetize as u will need to expand the server's player capacity. For a beginner photon pun2 is best

shut yarrow Oct 15, 2020, 2:02 PM

#

Agree emitotron and I also think the meaning of simple can be misleading. I'm using a very simple library, but only in terms of setting it up so it's ready to take connections and receive data. On the flipside there is no handholding with anything. A big portion of the work is in making the actual communication between server/client possible through packet structures that are easy to convert from/to binary, but also keeping their footprint small because you can't be wasting bandwidth while sending data. Another thing I stumbled into just by going through the experience without any formal education in networking is the fact that data can get corrupted while making its way to its destination, so that's another thing not being done by this 'simple' library. And another thing to consider is protecting data so it can't be easily snooped/mangled with by using something like wireshark, so encryption is another important thing. These are just a few of the downsides of using a library that is theoretically very simple (and I personally don't mind this) but I wouldn't recommend this to anyone who is starting or hasn't been programming for a decent amount of years.

terse relic Oct 15, 2020, 2:07 PM

#

As the person above stated, going full AAA server is not something you will be able to manage without years of exp but a simple server is prone to corruption, lag and hacks. Photon pretty much eliminates corruption and lag is based on whether your code is complex/simple and how heavy your stage is. However, you will face hackers if ur game is online multiplayer and incentives competition. For a starter I recommend making ppl create rooms and play with their friends rather than pvp

#

Btw guys. When using photon for a card game. All I have to do is make logic for one player and photon will handle the enemy side. A simple if(!photon view.mine) should handle the enemy player side right?

shut yarrow Oct 15, 2020, 2:10 PM

#

In theory yes, that's how you can differentiate between the local player and a remote player

#

Well let me try to rephrase. You need to do logic for both one way or another, but checking whether you own the photonview or not is an important aspect of it

#

I've done this in a very similar manner on my server. The server creates objects and assigns it a unique object ID. This object will also be assigned to a player which has his own unique ID. I then update all clients with which objects exist by passing them some information about what type of object it is, the object ID, and which player owns it. Then on the client side the player has a game object with a NetworkObject component on it, and he can know if he owns it by checking isLocalPlayer on the NetworkObject component

#

So in practice these objects can have any script on them which can handle both local/remote player, depending on whether the local player owns the object or not it either can control it, or just set the object state that the server sends

@jade glacier i found solution of the question that i asked yesterday

#

thanks

grizzled narwhal Oct 15, 2020, 2:36 PM

#

@jade glacier I've tried your HalfUtilities to compress my rotation vectors to float16 but I noticed precision is pretty bad on float16. Even for euler angles the loss is still .22 degrees. Just multiplying my euler angles * 1000 and casting to short gives more accurate results. Is this the wrong use case?

jade glacier Oct 15, 2020, 2:36 PM

#

half float is pretty terrible for anything not close to origin

#

what kind of values are you putting into it?

#

make sure you normalize rotation into a -180 to 180 range for best resolution

grizzled narwhal Oct 15, 2020, 2:37 PM

#

I use +pi -pi

jade glacier Oct 15, 2020, 2:38 PM

#

What are the actual values being given to the compressor?

#

-3.14 to 3.14 ?

#

that should yield pretty reasonable results. Though not sure why you are using that range.

#

To apply it to a transform you need it in degrees.

#

or a quat

#

HalfUtilities aren't mine btw, its a public library that everyone uses. But it does have significantly less resolution that normal floats.

And halffloats are not ideal for rotation, since rotation is range based.

#

@grizzled narwhal

grizzled narwhal Oct 15, 2020, 2:41 PM

#

Its rotation so -3.14 to 3.14 is the best format

#

it has 2^-9 precision

#

thats fine

#

but for anything else its pretty bad

jade glacier Oct 15, 2020, 2:45 PM

#

I would have to see your code. Not following what you are doing at all.

#

But regardless, half float isn't ideal for rotation.

#

Typically rotation is done with smallest three quat, or compressing euler floats to ranges.

I just started using PUN like 2 weeks ago

weak plinth Oct 15, 2020, 5:07 PM

#

yeah i added lag compensation using the docs

#

it reduced it by alot

#

but its still bad

jade glacier Oct 15, 2020, 5:12 PM

#

Lag Compensation similar to what is being described in the Pun2 doc on the topic is mostly only useful for shifting the timeframe of deterministic things, like projectiles.

#

Trying to lag compensate something non-deterministic like a player will produce insane rubberbanding at best.

weak plinth Oct 15, 2020, 5:17 PM

see im kinda retarded

i didnt understand a single line from that sentence

If I not mistaken, disconnect only allow when u in master server. When u in the room, you're in game server not master server, so you probably need to wait until you reconnected back to master server after you leave room then only call the disconnect

You have right.

I understood what happend.

When i connect with game server i don't open room yet. I have leave from room (#1). About (#2) you explain it 😉

But how can i disconnect from game server ?

what options do we have to make multiplayer in unity thats not p2p?

lusty crow Oct 16, 2020, 10:05 AM

#

there are headless unity server instances,
you could just write your own backend in any language,
and there are services that allow you to have some authoritative server code, I think (?) photon bolt is one of them?

grizzled narwhal Oct 16, 2020, 11:05 AM

You can use unity headless build or write your own backend (but that can't make of unity physics so you might have problems there)

#

looking for opinions from those who have looked into the most recent dotnets code, if someone was just starting a large scale multiplayer game today would you use the new official netcode or mlapi? If using the new dots networking, does that mean one has to use 100% dots entities for anything that needs to be synced?

hybrid arrow Oct 18, 2020, 8:01 AM

#

How on earth do you invoke the Instantiate(); function on the main thread..
I need to run the function that continuously listens for incoming connections in a infinite while loop in a separate thread to not deadlock the game.. Why do I feel like the solution to this will require some overly engineered and complex solution with 100 layers of abstraction added to it

lusty crow Oct 18, 2020, 10:41 AM

#

such things are often handled by a command queue,
you could have a queue or another collection type with locking, in other threads you enqueue tasks that have to be executed on the main thread,
and each frame, the main thread can poll for tasks to execute from that queue, if any are available, and execute them

stray moth Oct 18, 2020, 10:51 AM

Hey guys how does one update UI over the network for like what i am trying to do is set a lobby name so the other player can join it when it sees it on the room listing

lusty crow Oct 18, 2020, 10:58 AM

#

something common would be to have a central server, for example for match making (if you don't have that, you probably have a client as host, but then connection can be more tricky),

so if a client chooses to open up a lobby, the server receives a request, opens a lobby with a specific name or code, and it would send that code back to the client, then with the received package, you could update an UI element to display the text of the code or name, so that the player can share it with others

stray moth Oct 18, 2020, 10:59 AM

#

Using Pun btw

#

so I think thats taken care off

lusty crow Oct 18, 2020, 10:59 AM

#

then there should also be a kind of request to join a lobby, with the data payload being the name or code of the lobby

(oh sorry, not sure about framework specifics, but I think photon should have something for it yeah)

stray moth Oct 18, 2020, 11:00 AM

#

The create lobby works fine is just seeing the other lobby from the other player is not working

azure crown Oct 18, 2020, 4:25 PM

#

Would 200 players be possible in a single room with a low poly game?

#

Games like Battlefield 4 have up to 64 players per room, and it's not even low-poly.

jade glacier Oct 18, 2020, 4:35 PM

#

Poly doesn't matter. Number of objects sending data, and what kind of data matters

#

You aren't sending polygons with networking

proven crypt Oct 18, 2020, 5:21 PM

#

@azure crown yes as long as your backend infra is capable of handling that and what scale you are looking at, for example, GTA SAMP have server hosting 1000 players in a single world

From what im seeing, using a library like websocket-sharp or using a JavaScript plugin to implement seem to be the two options?

slow monolith Oct 19, 2020, 1:38 AM

#

        rotationX = Mathf.Clamp(rotationX, -lookXLimit, lookXLimit);
        Camera.transform.localRotation = Quaternion.Euler(rotationX, 0, 0);
        transform.rotation *= Quaternion.Euler(0, Input.GetAxis("Mouse X") * lookSpeed * Time.deltaTime, 0);```

#

so this seems to fix my camera shakiness

#

by adding time.deltatime

#

however this locks it to one axis

#

if I remove deltatime it allows me to look up and down, but the shakiness comes back

#

how did I get in the networking channel wtf

From what I can see, the only way to do this completly safely is force servers to use a sandboxed scripting language, but thats sorta a nuclear option I think. Are there other methods that people have used?

Is there a specific "best way" to save a json downloaded from an API in Unity?
I've heard everything from just storing it in Resources, storing it in Assets to encrypting it and hiding it among some random asset folder.
I don't need it to be super secure since it's just gonna store a rule set for my biomes that are generated.

In the editor or during runtime?

I do everything in code, so runtime.

grizzled narwhal Oct 19, 2020, 5:52 AM

@winter kraken Yes cause your question is impossible to answer. But I can say the following : dots atm is in beta so its buggy, there are little resources out there, and it will probably change until the release so code you write now will be broken in a few versions

i just want to know why this error is coming

📎 unknown.png

#

@jade glacier

#

like i have experience with unity

#

and made 2d games with it

#

i am trying my best to figure out

#

but

jade glacier Oct 20, 2020, 11:28 AM

#

That error says exactly what is wrong though

fallen frigate Oct 20, 2020, 11:28 AM

#

this error i so confusing

#

like i have put a debug statement when i connectedtomaster ()

#

which said i am already connected to master

#

and i can't able to join room after creating it

#

using joinrandomroom()

#

thats the whole situation

#

and i don't know what that error even mean ?

#

and for which callback i should wait?

#

@jade glacier

#

😒

You have to do the tutorials to understand the process of matchmaking and then joining a room.

#

No one is going to be able to help you if you can't get through the basics tutorials @fallen frigate

fallen frigate Oct 20, 2020, 11:35 AM

#

ok

#

thanks

jade glacier Oct 20, 2020, 11:56 AM

#

your particular error is saying you are connected to a game room already, and you aren't on the master server (matchmaking server)

fallen frigate Oct 20, 2020, 3:25 PM

#

yes but i already figured that out

#

how can i i know how many joined the room ?

#

like how to monitor those who joined the room

#

is there any method in photon ?

#

to do that ?

how can i i know how many joined the room ?
@fallen frigate you could manually count them by just in/decreasing an int whenever someone joins or leaves a room

#

is this the right place for netcode/ghost system questions?

#

I'm upgrading a project from earlier this year. I'm trying to get the index to my ghost in the ghost collection

#

there used to be a GhostSerializerCollection.FindGhostType<EnvironmentCubeSnapshotData>(); method but it appears to be gone

#

the samples show doing some loop and finding the ghost based on a component that is on it

#

the thing is my ghosts are not uniquely identified by any one component (currently, although obviously I could change that)

#

so I guess I"m looking for the ghost generated type? but there's no generate button anymore so I don't get a type for my ghost anymore?

#

how does this work? do I have to create a component unique to each ghost type?

#

📎 unknown.png

#

what does this generate?

#

where is Name used?

#

FindGhostType does not appear to be in the changelog

#

basically I want to get a prefab from EntityManager.GetBuffer<GhostPrefabBuffer>(ghostCollection) using some hard-coded value

#

do I just hard-code the index itself based on the order I added it in the ghost collection?

#

and just be super careful to never insert any, and leave empty placeholders for ones I delete?

#

there's gotta be a better way...

jade glacier Oct 21, 2020, 12:08 AM

#

I would definitely try Netcode questions in the DOTS channel, not many people in networking have even played with it.

Heya, does someone here have experience using Mirror?

I started using it some days ago and I've been having a problem syncing objects that are saved with the scene (as in, I can't spawn them)

grizzled narwhal Oct 21, 2020, 5:04 AM

#

@floral turtle Floating point math just inst deterministic across cpu arc (and os?)

#

There are deterministic physics engines but most are behind a pay wall

floral turtle Oct 21, 2020, 5:09 AM

#

@grizzled narwhal most modern intel and AMD processors both use the x86-64 architecture, so this would not require cross arch determinism

grizzled narwhal Oct 21, 2020, 5:09 AM

#

Try it out. It isnt

floral turtle Oct 21, 2020, 5:10 AM

Hmm, are you sure? I made a small C# app that does hundreds of computations that is determ across intel and AMD: https://gamedev.net/forums/topic/708301-floating-point-determinism-in-unity-physx-and-net-intel-vs-amd/

floral turtle Oct 21, 2020, 5:11 AM

#

I've read that article, but he only states that determ cannot be expected across different compilers, builds or architectures

grizzled narwhal Oct 21, 2020, 5:12 AM

#

And even on the same pc across different runs

#

PhysX isnt build for determinism too

floral turtle Oct 21, 2020, 5:12 AM

#

we actually have a functioning replay system that works on different runs/different machines, provided the CPU vendors are the same: https://twitter.com/roystanhonks/status/1318677036177784835

Then im guessing floating point math isnt deterministic across cpu brand?

floral turtle Oct 21, 2020, 5:14 AM

#

well, the test I did above shows a case where the arithmetic is deterministic with simple .NET apps

grizzled narwhal Oct 21, 2020, 5:14 AM

#

'Simple'!

floral turtle Oct 21, 2020, 5:14 AM

#

?

grizzled narwhal Oct 21, 2020, 5:14 AM

#

PhysX isnt simple

#

And it isnt build for determinism

#

The expert on determisim here is @graceful zephyr

#

But he will tell you roughly the same stuff

floral turtle Oct 21, 2020, 5:16 AM

#

I'm a bit confused

#

physx and Unity are clearly determ on same build, different machine, same arch same vendor. I am asking if it is possible for it to work across vendors. Are you saying it is not possible?

grizzled narwhal Oct 21, 2020, 5:17 AM

#

Probably not

floral turtle Oct 21, 2020, 5:18 AM

#

do you have a source for that? I'm finding it hard to find anything concrete

grizzled narwhal Oct 21, 2020, 5:20 AM

#

"The PhysX SDK can be described as offering limited determinism. Results can vary between platforms due to differences in hardware maths precision and differences in how the compiler reoders instructions during optimization."

#

https://docs.nvidia.com/gameworks/content/gameworkslibrary/physx/guide/Manual/BestPractices.html

floral turtle Oct 21, 2020, 5:21 AM

#

yes, I have read that. I am looking for a clear answer on whether it should be deterministic across vendors on the same arch

grizzled narwhal Oct 21, 2020, 5:29 AM

#

Dont have that

floral turtle Oct 21, 2020, 5:34 AM

#

okay, thanks anyways @grizzled narwhal

graceful zephyr Oct 21, 2020, 6:44 AM

#

@floral turtle So as you know it's possible to get physx determinism on the same arch/compiler/etc. thing... if this is usable or not depends on what ur trying to do .

#

If you want this to be deterministic you always have to step the simulation forward, you can never reset any objects, etc.

#

You can't do "predict-rollback" thing with that type of determinism

#

Because the second you reset objects, the determinism promise is gone

#

You also can't have anything from the 'outside' influencing the physics simulation like animation systems, etc.

floral turtle Oct 21, 2020, 6:49 AM

#

@graceful zephyr yeah, definitely not prediction with rollback...I'm under no illusions at how difficult that is to build :S

Not primarily planning to use it for networking (brought it up in this channel since I figured it would be where the knowledge was). Mainly seeing if it is something that can be solved with compiler flags/configuration to allow users to share replays cross CPU vendor. Using it for deterministic lockstep networking w/ input lag would be an interesting stopgap to moving to a more powerful system (like quantum), but the cost to users is significantly higher when a multiplayer session desyncs versus a replay, so probably not worth the investment

graceful zephyr Oct 21, 2020, 6:49 AM

#

So using it for like... client side prediction

#

And getting "close enough" to determinism

#

It all works for

#

But like hanging your entire game on physx being 100% deterministic

#

I wouldn't dare

#

At least not without being able to compile physx myself

#

and make changes

#

If you get a year or two down the line in dev, and then realize oh wait there's this specific scenario which breaks the determinism on this arch/setup/etc. whatever

#

I'd never ever dare to hang my game on something

#

I don't have control over

#

When its such a core part

floral turtle Oct 21, 2020, 6:53 AM

#

👍 that is mostly the kind of opinion I was looking for. It's easy for us to just flag replays if they are captured with intel or amd, and warn users that sharing may lead to desyncs...it's a nice feature, but not critical

wide bolt Oct 21, 2020, 7:20 AM

#

Hi guys, so I’ve been making some prototypes for some game ideas I’ve had using Unreal. I’ve found the engine really uninspiring (I know that sounds weird) and there’s something about Unity that I really love

The one game I want to make is multiplayer however. Not overly complicated but still multiplayer.

Do you guys find Unity is a big pain for networking using Photo or other plugins? Or is it more so just time consuming but enjoyable?

fallen frigate Oct 21, 2020, 10:02 AM

#

how to make my photon manager script act like an singleton in unity ,like it should not get affected by changing scenes ?

#

also i am trying to make other player join the room so we can move together in a scene but only host can start the level

#

and i want my lobby to show players name who joined and arrange them in a column

#

please any experienced in pun 2 help me

slow monolith Oct 21, 2020, 10:50 AM

#

Hey so I'm trying to understand prediction for a multiplayer game. Can I do all of the prediction clientside based off the user's current velocity?

#

How its going to work is just a simple websocket server. Client sends his rotation and position to the server, and the server sends back the same information of all players in the lobby

#

Third day in unity so idk if this will work. Also will it be a problem with users that have low framerates?

#

also how many ms should every request be

jade glacier Oct 21, 2020, 11:36 AM

#

I would post that in the DOTS channel. Very few to no Netcode users in this chan usually @patent magnet

somber drum Oct 21, 2020, 1:10 PM

#

@wide bolt photon is said to be the easiest way to get connected and playing.. Though it has limitations in terms of scaling, the easy is weighed vs the cost of leaving the "educational" tier of players allowed online at once. Unitys networking itself is a mess to be honest, its not happening as far as I'm aware so you would be relying on a third party like photon or community extensions reviving collapsed systems like unitys old networking "unet". "mirror". Which to be fair is easy enough, has a great community behind it. (With no ccu paywall)

#

If its a small uncomplicated game with a small lobby definitely go with photon

jade glacier Oct 21, 2020, 1:13 PM

#

depends on how scaling is defined

#

Phasmophobia is doing like 100K+ CCUs

somber drum Oct 21, 2020, 1:15 PM

#

Sure, everything is possible and of course we're only biased to our experience and opinion

jade glacier Oct 21, 2020, 1:15 PM

#

Rooms in photon products are limited by the same factors as any other platform. How much data each user is pushing the main factor.

somber drum Oct 21, 2020, 1:15 PM

#

Right but its known with photon or any cloud service data is expensive

jade glacier Oct 21, 2020, 1:15 PM

#

Mirror and Pun2's limits to users per "game" are largely tied to how efficiently the dev is serializing and sending.

#

They charge based on usage of course. The alternative is either hosting instances, or doing a Nat Punch system and having clients host.

somber drum Oct 21, 2020, 1:16 PM

#

We're talking best case really though here

gleaming prawn Oct 21, 2020, 1:16 PM

#

Servers are expensive with the "free" products as well

#

Except for the "free" steam thingy...

#

after you gave them 30% of your rev

somber drum Oct 21, 2020, 1:17 PM

#

True, and I think with all the heavy lifting photon does for you its worth the cost

gleaming prawn Oct 21, 2020, 1:17 PM

#

So classifying a product as expensive is relative...

jade glacier Oct 21, 2020, 1:18 PM

#

You can do player hosted, and skip the relay backup, and rely on just natpumch for the cheapest route. But that will leave a lot of players in the cold. But it is an option.

#

Not really a winning business plan, but an option

gleaming prawn Oct 21, 2020, 1:18 PM

#

And that's why nobody does that

#

That's what Unity originally shipped with, the old defunct UN (Unity Networking), with a master server to run punch (raknet underneath)

jade glacier Oct 21, 2020, 1:19 PM

#

Mirror and Pun2 and most other products get increasingly difficult to develop once you pass 16 players per game session

#

around the 64 player count point, you need to be an experienced dev. Regardless of netlib.

somber drum Oct 21, 2020, 1:21 PM

#

I can't even blame it entirely on my own ignorance, nearly everyone if not everyone I've spoken to about photon says its great for smaller gigs but be warned you'd get more bang for your buck going with mirror, maybe they dont know what they're talking about or maybe its just a matter of optimising

gleaming prawn Oct 21, 2020, 1:21 PM

#

If they have finsihed their game and have the numbers to show, then sure

jade glacier Oct 21, 2020, 1:22 PM

#

I haven't seen any Mirror releases, or their revenue numbers so can't comment.

gleaming prawn Oct 21, 2020, 1:22 PM

#

Among Us runs their own thing (funny enough, very similar in approach to photon), so he could run down the costs well

#

Fully relayed, client authoritative, etc

jade glacier Oct 21, 2020, 1:23 PM

#

Phasmophobia is on Pun2, and the consume insane quantities of data

gleaming prawn Oct 21, 2020, 1:23 PM

#

Phasmaphobia is photon (and I'm sure their bank account would not even get scratched by what they pay us...:)

jade glacier Oct 21, 2020, 1:24 PM

#

I have been talking to one of their net devs about helping them implement bitpacking and other compression.

gleaming prawn Oct 21, 2020, 1:24 PM

#

can't disclose anything, of course... except it is PUN2, as lots of people know.

somber drum Oct 21, 2020, 1:24 PM

#

Fair enough, average dev probably wont need to worry about hitting any ceilings either

jade glacier Oct 21, 2020, 1:25 PM

#

I don't know their numbers, and couldn't share if I did yeah.

#

All cloud models are designed to scale endlessly, that is the appeal of hosting that way.

#

When people say Pun2 or Mirror can't scale, they typically mean the number of users in a game... which is all libraries.

gleaming prawn Oct 21, 2020, 1:26 PM

#

And it also gets cheaper as you move up the ladder

#

So...

somber drum Oct 21, 2020, 1:26 PM

#

If you've got a good consistent revenue model ofc, I guess that goes without saying

gleaming prawn Oct 21, 2020, 1:26 PM

#

Ye, SCALE normally means:

you can host 1 million or more CCU without effort?

jade glacier Oct 21, 2020, 1:27 PM

#

it scales down as well. If your users drop off, your costs drop of.

#

The appeal is it is a fixed operating cost, that is directly tied to usage.

gleaming prawn Oct 21, 2020, 1:27 PM

#

Honestly David, its a fair model for the customer more than us... Other industry sectors have more "hungry" models... But that may be subjective, of course...:)

jade glacier Oct 21, 2020, 1:27 PM

#

Unlike buying 20 servers and hosting them yourself.

#

CCUs just scare hobbyists. But to anyone running a business, the predictability of the costs involved are a positive.

somber drum Oct 21, 2020, 1:28 PM

#

I must be talking to the wrong folks I guess, clears photon up for me at least

gleaming prawn Oct 21, 2020, 1:29 PM

#

photon is also a lot more than PUN

somber drum Oct 21, 2020, 1:29 PM

#

I know as a game dev id rather worry about that, than managing my own server fleet or whatever lol

jade glacier Oct 21, 2020, 1:29 PM

#

Hobbyists tend to gravitate toward Mirror because of the allure of "unlimited free", but obviously it never is. Someone wants to get paid for using their bandwidth.

gleaming prawn Oct 21, 2020, 1:29 PM

#

Ask the Among Us developer his opinion on Photon...:)

#

He's not our customer (anymore), but he normally recommends photon

somber drum Oct 21, 2020, 1:30 PM

#

Cheers guys, ill do more research, currently invested in mirror but may change I think it may fit my needs more

jade glacier Oct 21, 2020, 1:30 PM

#

The reason to use Mirror should be because you want a Unity based server... not for money reasons.

gleaming prawn Oct 21, 2020, 1:31 PM

#

Mirror is also popular...

#

Not saying bad things about it

jade glacier Oct 21, 2020, 1:31 PM

#

Pun2 vs Mirror should be a choice based on architecture.. not trying to get away with "Free"... because neither are.

Might want to paste your code, not sure from what I seeing so far.

#

In a bin preferably, since its likely your entire conntection cs file.

#

https://doc.photonengine.com/en-us/pun/v2/lobby-and-matchmaking/matchmaking-and-lobby#lobbies

Are you working for the docs on dealing with lobbies and matchmaking?

#

Not seeing anything in your order of events there that suggests the need for lobbies?

#

So it should be pretty boilerplate code to get a room started.

With a plugin (Phaton Networking) I always get this error!
Why is that?

jade glacier Oct 21, 2020, 7:36 PM

#

Just the usual Unity noise as far as I know.

shut yarrow Oct 21, 2020, 11:26 PM

#

I'm trying to find a way to get rid of jitter in my movement. The client sends 10 packet/sec to the server and the server sends 10 packets/sec to clients and attaches a timestamp (similar to Time.time which is just an incrementing counter) to the packet. Upon receiving of the packet on the clientside I'm using the timestamp to interpolate the position and rotation but I still experience serious jitter. How can I resolve this? Here is a general breakdown of how it works on the client

float timestampprev = 0;
float timestamp = 0;

void OnNetworkUpdate(Packet packet)
{
    BinaryStream stream = new BinaryStream(packet.data);

    timestampprev = timestamp;
    timestamp = packet.timestamp;

    for(int i = 0; i < m_networkObjects.Lenght; i++
    {
        Vector3 position = m_networkObjects[i].gameObject.transform.position;
        Quaternion rotation = m_networkObjects[i].gameObject.transform.rotation;

        NetworkObjectState nos = new NetworkObjectState();
        nos.position = stream.ReadVector3();
        nos.rotation = stream.ReadQuaternion();
        
        m_networkObjects[i].gameObject.transform.position = Vector3.Lerp(position, nos.position, (float)timestampprev * 10);
        m_networkObjects[i].gameObject.transform.rotation = Quaternion.Lerp(rotation, nos.rotation, (float)timestampprev * 10);
    }
}

#

The jitter is both on translation and rotation

#

I feel like maybe I should interpolate between previous position that server sent, and the new position I just received, instead of interpolating between whatever the position the object is at and the received position

#

Or maybe it has something to do with my timestamp which isn't between 0 and 1?

jade glacier Oct 21, 2020, 11:30 PM

#

OnNetworkUpdate is the same timing segment as Update?

shut yarrow Oct 21, 2020, 11:30 PM

#

I'll have to check actually give me a sec

jade glacier Oct 21, 2020, 11:31 PM

#

Typically you would see interpolation inside of Update()

#

OnNetworkUpdate looks like either a fixed timing, or some kind of arbitrary timing based on your networking.

shut yarrow Oct 21, 2020, 11:32 PM

#

No actually it only runs whenever a new NetworkObjectState is received

jade glacier Oct 21, 2020, 11:32 PM

#

Then you are baking in jitter

shut yarrow Oct 21, 2020, 11:32 PM

#

So yeah possibly kind of arbitrary although in theory it runs 10 times a second

jade glacier Oct 21, 2020, 11:32 PM

#

In theory, it happens whenever your packet arrives.

#

which is internet noise.

#

Interpolation is the act of translating frames into the screen refresh updates.

shut yarrow Oct 21, 2020, 11:33 PM

#

Yes I see your point, so I should have it run on a fixed rate and what if there's no data to update with?

jade glacier Oct 21, 2020, 11:33 PM

#

So you always lerp in Update

#

No data = time to extrapolate

#

or let things hang

shut yarrow Oct 21, 2020, 11:34 PM

#

With extrapolate you mean like prediction?

jade glacier Oct 21, 2020, 11:34 PM

#

This is why networking uses buffers

#

Not really the term I would use, since prediction has other meanings in networking

#

just extrapolation

shut yarrow Oct 21, 2020, 11:35 PM

#

Never have done that before, I know interpolation between 2 points, but extrapolation is the opposite right?

#

So you keep moving an object at same speed/direction it did with last data point?

jade glacier Oct 21, 2020, 11:36 PM

#

Just use an Unclamped lerp

#

value > 1 = extrapolation

shut yarrow Oct 21, 2020, 11:37 PM

#

Do I still have to change the function so it runs on fixed rate or is that just something you recommend doing?

jade glacier Oct 21, 2020, 11:37 PM

#

How you implement it is up to you. But if your buffer is dry, you have to either hold the last value, or extrapolate something

#

you get the concept, I can't really give you much more without actually writing your protocol with you.

shut yarrow Oct 21, 2020, 11:38 PM

#

I understand, just trying to do this without having to rewrite much although I feel like that would be the better way

slim ridge Oct 21, 2020, 11:39 PM

#

i found that to be the case when i was working through this... still am

shut yarrow Oct 21, 2020, 11:39 PM

#

Wouldn't even be that much work probably, just have to rethink the strategy on it because I did it a little too straightforward without thinking about the implications

#

I did it similar as I did with PUN in the OnPhotonSerializeView, but I don't know anything about the implementation of that function, just that it runs whenever there's data

slim ridge Oct 21, 2020, 11:40 PM

#

dont trust timestamps btw

shut yarrow Oct 21, 2020, 11:41 PM

#

Yeah kind of naive I know

jade glacier Oct 21, 2020, 11:41 PM

#

You can't lerp unless you have a tick defined and some kind of buffer

#

If you want to avoid making that system, try using MoveTo and RotateTo rather than lerping

#

Those let you set the rate of change as a way of damping changes. Won't be perfect. But you can't get perfect without proper lerping in Update.

#

And you can't lerp without a proper buffer.

shut yarrow Oct 21, 2020, 11:43 PM

#

Thanks I'll give it some more thought instead of trying to rush it, you've given me multiple possible solutions so I have to see what works best given circumstances

jade glacier Oct 21, 2020, 11:45 PM

#

Proper transform syncs are hard. There is a reason all of the networking libraries have terrible implementations. They require a proper tick engine to do right.

shut yarrow Oct 21, 2020, 11:46 PM

#

I feel you and I'm guilty too haha

jade glacier Oct 21, 2020, 11:46 PM

#

Which library are you using?

shut yarrow Oct 21, 2020, 11:46 PM

#

I've seen you talk about tickbased simulations before but haven't tried yet to implement that

#

For networking you mean?

#

ENet

jade glacier Oct 21, 2020, 11:47 PM

#

Everyone makes a bad transform sync to start. You have to try the shortcuts to find out why the shortcuts don't work.

shut yarrow Oct 21, 2020, 11:47 PM

#

Yeah this is more like a practice project for me to see what problems I have to deal with if I want to make something serious

slim ridge Oct 21, 2020, 11:50 PM

#

here's how i did it for input + prediction strategy

- server sends current tick to client upon succesful connection
- client caches this value as offset
- client begins counting ticks at same rate as server.
- client subtracts offset from received input.
- client adds offset to outgoing input.

shut yarrow Oct 21, 2020, 11:50 PM

#

I either find no useful information at all, or it's some long boring essay and I lose focus quick to absorb all the information

#

Thanks @slim ridge that doesn't seem too complicated to keep some kind of timesync that's not floatingpoint based

jade glacier Oct 21, 2020, 11:52 PM

#

Most of us just use FixedUpdate as the tick, since its the same tick engine that runs physX and most of Unity internals.

slim ridge Oct 21, 2020, 11:53 PM

#

ya, count ticks as int or long or even short

shut yarrow Oct 21, 2020, 11:53 PM

#

But that would mean I definitely need to have a buffer right

jade glacier Oct 21, 2020, 11:53 PM

#

byte is plenty

shut yarrow Oct 21, 2020, 11:53 PM

#

There's no buffer currently

jade glacier Oct 21, 2020, 11:53 PM

#

unless your tick rate is super high

slim ridge Oct 21, 2020, 11:54 PM

#

i'm too scared to try byte lol

#

i'm using ushort right now

jade glacier Oct 21, 2020, 11:54 PM

#

its 4 seconds of buffer at 60 ticks per sec

#

Any packets that late, aren't worth trying to resimulate.

shut yarrow Oct 21, 2020, 11:54 PM

#

I'm doing 10 per second so not very extreme

#

Not doing any prediction either and if packets get lost so be it

#

I don't want to overcomplicate a project like this, if it looks good (and no obvious jitter is visible) I think it's good enough

jade glacier Oct 21, 2020, 11:56 PM

#

Try MoveTo and RotateTo rather than lerping then

#

That is what the Pun2 vanilla sync does and most people are fine with it.

shut yarrow Oct 21, 2020, 11:57 PM

#

That works without buffering values?

jade glacier Oct 21, 2020, 11:57 PM

#

It is always rotating or moving toward the latest value at a fixed velocity/ang vel

#

About the best you will pull off without a proper buffer.

#

Just moving your stuff to Update for interpolation is a start no matter what.

#

you can't interpolate outside of Update()... by definition.

shut yarrow Oct 21, 2020, 11:59 PM

#

I might give that a try. Got another question related to this jitter however. My server is in Germany and I live in Suriname (South America). When I connect with 2 clients to it (both on my computer) I don't see jitter, but when a friend from America joins I see him jitter around and he sees the same, so kind of curious how that works

slim ridge Oct 21, 2020, 11:59 PM

#

prolly the timestamp

jade glacier Oct 22, 2020, 12:00 AM

#

You can do crafty things having a timestamp

#

they are expensive and clumsy, but as long as you have it you can use it.

shut yarrow Oct 22, 2020, 12:00 AM

#

That makes it more difficult to test it because it seems to look fine untill someone from another location joins

#

So not sure why it doesn't jitter because both my clients need to send data to a server that doesn't run on my local machine

#

In a way I expect to see the same problem

#

Eitherway I guess this method I'm using isn't really bulletproof

jade glacier Oct 22, 2020, 12:02 AM

#

You aren't buffering properly, so you are going to see the internet jitter and framerate jitter in your rendering.

shut yarrow Oct 22, 2020, 12:02 AM

#

Yeah gonna try the MoveTo/RotateTo method and see how that plays out

So I’m working on a game, and I plan on implementing some sort of multiplayer further down the road (like 8-12 months down the road), but I know little to nothing about networking. Does anyone know any good tutorials out there that covers this topic pretty good in depth?

somber drum Oct 22, 2020, 5:42 AM

#

it's a good idea to start building with multiplayer in mind, it's not going to be something you'll want to start with 8-12 months of offline code made, pretty much from the ground up

#

Dapper Dino has some good stuff

#

depending on your needs, different channels tend to teach in depth for what they use, I watched this guy for mirror he does a great job explaining the general idea

Does steam host servers? Planning on releasing a game in steam so I would like to know for my games multiplayer.

If not, I will just use Photon PUN

gleaming prawn Oct 22, 2020, 8:15 AM

#

@slim ridge

#

Not sure I'm saying something you already know, but this:

- client begins counting ticks at same rate as server.

Caught my attention

#

You know that hardware clocks DRIFT, and that stopwatches will not keep aligned... Besides the network "jitter" may make your original alignment bad in the first place...

#

You need to keep CONSTANTLY fixing/correcting the local clock using the server clock as reference (needs to be send down frequently)

#

If you do not do this, you will get very bad "rifting" in any slightly longer game/match

to sync skins, what i have to do

#

You need to ask a SPECIFIC question to get help.

fair cosmos Oct 22, 2020, 4:11 PM

#

i mean by ids

#

i have to make an array of skins with ints(ids) on server and then compare stuff with that?

#

i got some anwsers before forget to take ss

jade glacier Oct 22, 2020, 5:09 PM

#

Which library? @fair cosmos

#

Every library has different means of sending messages.

fair cosmos Oct 22, 2020, 6:08 PM

#

Need a general answer

#

What is needed on server and what to client and what to do when changes happen

#

Photon or Mirror both works

grizzled narwhal Oct 22, 2020, 7:08 PM

#

Yes but this is for specific questions

#

Its pretty easy to do with rpcs and you should be able to do that if you want to do multiplayer!

Well sorry for fucking noob English, i want to know is i make an array of skins and assign them a id this wiill do the server, on the client it will pass command N get data back

#

Somethingg like the actual process what games do to sync large amount of stuff

#

By iDs

floral turtle Oct 22, 2020, 10:16 PM

#

@fair cosmos there's a lot of ways to do this, but as a simple way it's fine to just send an ID then have the client load the correct skin

slim ridge Oct 22, 2020, 10:21 PM

#

yes, the basic strategy is to keep this information in a database. only the server accesses this database and serve the data to clients

#

then in your client build, you include the map of skin id -> skin asset
server tells client which skin id he can use

left knoll Oct 22, 2020, 11:16 PM

#

I wonder when you want to test multiple clients, is there a way to launch multiple clients through the Unity Editor or you have to build an .exe and run that multiple times?

jade glacier Oct 22, 2020, 11:26 PM

#

It is a pretty common practice to do a project mirror and have two editors open. I don't recall the software used for that though.

#

I typically keep all networking development separate from the complete game though. leaving out all graphics and textures makes a huge difference.

I'm having a particularly weird problem and hoping someone can help me out.
I am doing a Webrequest on some of my android devices. They both run Android 10.
Same apk is build on 2 of my devices.

On 1 the webrequest completes just fine and everything is dandy (OnePlus 5T)
On the other however, the webrequest just keeps going. Never returns an error or finishes the webrequest (Samsung Galaxy Tab S7+)

The webrequest itself is called in a coroutine "yield return wr.SendWebRequest"

What could be causing this?
Please @me if you reply to this, thank you!

@gleaming prawn Yes, but there is no other solution with server authoritative + lag compensation and client prediction as easy to implement out there like Unity's solution

#

And I can't really pull off in-house networking solution on my own

#

Realistically

gleaming prawn Oct 23, 2020, 9:52 AM

#

There is

#

Bolt does exactly that since launched in 2015

#

if THAT is really what you need, you should give it a try

#

The other solutions are still in pre-2015 era, in that all they care about is Data-Transfering (which is a topic some people here discuss a lot: the key to a netcode solution is not how to transfer data, is how to control the simulation)

#

AFAIK, the netcode solutions that work on that (simulation, not only transfering data) are:

SpatialOS
Photon Quantum
Photon Bolt
Unreal Networking, Source Engine networking, etc (not Unity)
Unity's NEW netcode (not ready)

#

AFAIK all others are lower-level (in that they offer you a few was to sync data, but nothing in terms how that helps you build a tight networked gameplay.

#

I might be wrong, of course.

silver steeple Oct 23, 2020, 3:13 PM

If it makes yall feel anybetter, they hiring a buncha networking people. It's atleaast a priority

they seem to have the right idea for some stuff, but does anyone know if they have actually achieved cross platform determinism with Unity Physics? It's advertised as deterministic, but I'm curious if that includes between platforms and builds: https://docs.unity3d.com/Packages/com.unity.physics@0.0/manual/index.html#:~:text=Unity Physics is a deterministic,Havok Physics team at Microsoft.

Good morning folks! Intermediate-level programmer looking to make my first networked game. I have a "digital tcg" idea in mind and I think that is probably some simpler networked code since it is turn based. I actually found a series from the develoeprs of "Socket Weaver" of doing a GoFish style card game over network. Do any pros out there think that is overkill or have even eard of SW? Or is it better to just do my own API calls to a C# library running on cloud or something to control the state of game?

I liked the fact that this SW SDK helps manage lobby and matchmaking logic.
