I would start though if you are looking into learning how to sync transforms well with a 2-4 player thing
Haha, this is what I'm still doing 9 years later. Every beginner including me wanted an MMO, but experienced game designer/programmer realize that MMOs are simply not fun to play, neither to develop.
Massive amount of players in close proximity does not guarantee that the game will be fun to play, it's quite the opposite - it brings serious game design challenges.

I imagine it's primarily about production issues than design issues.

I avoid static unless its like player configs for the local player. Say every player has an inventory, is it ok to use static variable for the current selected item for the local player's inventory (the one belonging to the client) or should i just avoid that and use events? Im currently doing events but need a second opinion.

#

probably a dumb question, ill just stick to events..

Guys can anyone help me regarding an infinite loop problem? Basically i have a do while loop that keeps checking for a static variable in another class, and when the variable is set to false, the loop should exit, and the scene shoul load...but it doesn't...i mean, at some point the loop stop checking for the variable, and even the Debug.Log() doesn't show, so i think there is an infinite loop somewhere...This is the class that has the do while loop https://hatebin.com/mqseduqejt and this is the class that has the static variables that the loops keep checking https://hatebin.com/tvqeaozthz Can anyone tell me what i'm doing wrong? ...even if i do return in the second class, the program keeps checking for messages. Only if i disconnect one client, and the other one receive DISCONNECTED, the loop exit...is so strange....

Guys, can somebody say what exactly is this error
SpawnObject for RedPlayer Variant(Clone) (UnityEngine.GameObject), NetworkServer is not active. Cannot spawn objects without an active server.This error pop up whil I conect to server from unity as a client
This is the code

public class TeamSetup : NetworkBehaviour
{
    [SerializeField]
    private GameObject RedPlayer;
    GameObject PlayerPanel;


    public Transform[] PlayerPositions;
    //public Transform[] GreenPlayerPositions;
    //public Transform[] BluePlayerPositions;
    //public Transform[] YellowPlayerPositions;

    void Awake()
    {
        PlayerPanel = GameObject.Find("PlayablePanel");
    }

    private void CmdPlayerAddition()
    {
        SpawnPlayers();
        RpcPlayerAddition();
    }

    private void RpcPlayerAddition()
    {
        Debug.Log("Client RPC Executing");

    {
        for (int i = 0; i < PlayerPositions.Length; i++)
        {
            GameObject player = Instantiate(RedPlayer);
            player.transform.SetParent(PlayerPanel.transform);
            player.transform.position = PlayerPositions[i].position;
            player.transform.localScale = (player.transform.localScale) * 0.2f;

    }

}

Guys, can somebody help me please?

gleaming prawn May 18, 2020, 7:58 AM

#

You really should ask on mirror discord

#

Here you have people who doesnt even know what mirror is

versed rock May 18, 2020, 8:26 AM

#

another question, any have if Websockets for a MMO is a viable option?

#

i think is a bad idea for bandwitch

gleaming prawn May 18, 2020, 8:32 AM

#

Bad idea: mmo

#

Several developers already told you that, believe then

#

Them

#

Start with something very small, that's all there's to it

#

Anything you ask about mmo people will just laugh inside, that's the truth

versed rock May 18, 2020, 8:43 AM

#

thanks for the advice but all people do the same. I know others devs have try to create a MMO, but maybe other people who ask about this questios meaby have experience with developing videogames creating offlines games and now they try to create / investigate about MMO or backend structure.
And all answers are ... bad idea but don't answer to the question.
Why i'm going to ask another question if the answer is going to be the same?

#

maybe the first question is , have you experiencie? because i know if u don't have experience if a bad idea create a MMO but damn people who have experience in offline videogames, why try to ask to another devs if the anser is going to be the same?

gleaming prawn May 18, 2020, 9:16 AM

#

I do

#

I do have experience with online (and I know how to create MMOs)

#

And the answer is: don't do it

#

Let me try to rephrase it...

#

If you are into home-improvement... You like to paint, to do some rebuilds, maybe some furniture... Very DIY guy, right?

#

Then you come to an engineer and ask this question:

Hey, how do I build a skyscraper by myself?

weak plinth May 18, 2020, 9:18 AM

#

@orchid cairn for some reason that isnt working for me

gleaming prawn May 18, 2020, 9:18 AM

#

That's what you are asking

#

Does it even make sense to ask this question (how to build a skyscraper)? No, it does not...

#

That's what everyone is trying to tell you...

#

@versed rock

#

It's not that simple, not nearly that simple

versed rock May 18, 2020, 9:19 AM

#

yeah but the question is different, the question is not how to build a skyscraper, is "can i use paper to create a skyscraper?"

#

i simple, create MMO with WEbsocket? right or bad idea?
Bad idea for bandwitch, maybe depends of the type of project

#

but if the first anser is

gleaming prawn May 18, 2020, 9:20 AM

#

Yes, but that is still misleading, because paper is 1 out of 473 thousand other things

versed rock May 18, 2020, 9:20 AM

#

No, bad idea create a MMO

gleaming prawn May 18, 2020, 9:20 AM

#

You have no idea what you are taking about

versed rock May 18, 2020, 9:21 AM

#

is like, ok, so if everytime i have question i have no, why question?

gleaming prawn May 18, 2020, 9:21 AM

#

An MMO has SEVERAL connections, to several servers (multiple backends, for different features, multiple gameplay servers)

#

May you use http for some rest operations, yes...

#

may you use TCP, yes

#

may you use UDP, yes

#

You'll probably need all of them in some fashion

#

Will you build an MMO using ONLY websockets? Probably NO

#

Notice I'm taking my time to answer, although you'll probably not understand

versed rock May 18, 2020, 9:23 AM

#

yeah, but this is a better answer than no, bad idea.
Now i thinks Websocket are bad idea for bandwitch and maybe another things

gleaming prawn May 18, 2020, 9:23 AM

#

The CORRECT answer is REALLY: do not try to do an MMO, try something else...

#

You'll have more fun and more success and learn more

#

10 years later you think again about mmo

#

Now i thinks Websocket are bad idea for bandwitch and maybe another things
It's not because of that

versed rock May 18, 2020, 9:23 AM

#

and other things

gleaming prawn May 18, 2020, 9:23 AM

#

It's just, don't...:)

#

You are asking if using paper is good for building a skyscraper, and concluding NO, it is not because paper does not resist traction

#

The correct answer is:

paper IS used to build skyscrapers
in the blueprints
in the drywalls

#

Among several other materials

versed rock May 18, 2020, 9:26 AM

#

You are asking if using paper is good for building a skyscraper, and concluding NO, it is not because paper does not resist traction
@gleaming prawn this is the type of answer i think, and yeah ofc you can add the idea of .... maybe is no the best idea for start if you don't have experience

I think it helps more than a no, bad idea

#

bad idea create a MMO

gleaming prawn May 18, 2020, 9:26 AM

#

That's still the correct answer: do not do it

versed rock May 18, 2020, 9:26 AM

#

👍

gleaming prawn May 18, 2020, 9:26 AM

#

Most people don't even answer, just laugh (that's the truth)

versed rock May 18, 2020, 9:27 AM

#

yeah i know

#

but all kinds of help appreciated

#

thanks @gleaming prawn

west galleon May 18, 2020, 1:06 PM

#

I'm one such person who would have laughed. But I'm not sure if that violates the rules of this discord.

#

but nevermind whether or not you have the technical know-how to make it. Can you afford to host one?

#

Should we assume you want to make an MMO and sell or is it a learning exercise?

Hi, im currently working a on a net lib that will only be used within a local wifi. Im currenlty using TCP but i have concerns that this would slow down sending/receiving. I would change to udp but scared of adding a reliable layer on top of udp(since i dont know how and also im limited with time). What would you guys do or do you have any suggestions ?

slim ridge May 18, 2020, 1:40 PM

#

validate your concerns with experimentation 🙂

#

on local wi-fi you probably wont have much lag or packet loss

Hello, I'm new in photon,

I have a problem, but before I’ll explain a little bit what my game looks like : it's a 2d game where there is a single player mode where you can farm rarer weapons than others have armor, improve hit points, have passive or active artifacts ... A kind of solo "rpg"

So this is my problem now, I have instigated a "pvp" system in 1v1, for the moment the room system works but the problem is that I would like our characters with all their characteristics to be instantiated with the opposing player, (he doesn’t there will be no movement, it's just a question of look) the problem is when we do a prefab in the resources folder we can not have all the mesh of the solo mode, the 2 players are identical with the basic skin and equivalent characteristics. So I would like to find a way to instantiate your own character without passing the prefabs in the resources folder!

I inquired and saw things like" viewID" or "RPC" but it did not work for me, or simply I did it wrong maybe?

Any help would be welcome !!!

Thank you for your help,

Cordially.

stiff ridge May 18, 2020, 2:48 PM

#

You need to come up with a way to summarize the look of the character. Photon allows you to send Hashtables, object[] and more but preferrably, the look is a lean byte[]. Then you can send it.
If this doesn't change a lot (or at all) you can set it as Player Custom Property.

Hello there, i wanted to ask if someone could give me a hand on a ai asset i got, the ai works great and it attacks the player, but now i want to make it run through multiplayer, but the issue is that i need to drag and drop only 1 player to ai script so that it can work, the ai ignores the other player

#

Im not really familiar with ai in multiplayer

#

I thought maybe ifi could make it with tags, soo the ai only attack the game objects that have the tap (player)

guys i am working on a lobby for my game server, and i was messing around about getting current server status and some HandShaking info from the server, but without actually connecting to it, i was thinking on adding rest API and retrieve the info using http, you guys think its a good idea?

#

i think opening a tcp for real time communication is over kill for this 😕

#

also i don't want my actual tcp connections to be affected by some one not actually playing on the server

Do you know if Photon automatically switch the master if it leaves the room?

sacred patrol May 18, 2020, 5:44 PM

#

I think so

drowsy vortex May 18, 2020, 5:45 PM

#

so i decided to give a go with HttpListener in async mode, let's see how this goes.

graceful zephyr May 18, 2020, 6:47 PM

#

so dots netcode pushed another year ?

drowsy vortex May 18, 2020, 6:49 PM

#

i am using my own netcode

#

these frameworks they make have too much overhead, i like to be able to optimize and fine tune my code 🙂

#

crush those milliseconds 😄

#

so the rest API worked perfectly

#

i think i made the right call

#

it runs in a separate thread, beautifully

#

my server don't even notice it happened 😄

jade glacier May 18, 2020, 9:13 PM

#

@cedar cloak yes, a new client becomes the master.

sacred patrol May 18, 2020, 11:02 PM

#

Honestly I'd use something else than Unity to crush milliseconds. This engine is more likely fitting the "just get things done" role.

#

Rapid prototyping, exploring new mechanics, preparing demo for a publisher, learning how to code, getting a contract job done - that's a bliss. But that's all there is to it.

In addition I would like that as long as the weapon (or other) is not bought, they remain on the market for an indefinite period.
Thank you for your help.

Im trying to make a combat system in unity but when ever the player kills another player it kills every player with the kill player script on, how would I fix this?

#

here is the main part of my code

📎 unknown.png

stray scroll May 19, 2020, 1:39 PM

#

You're telling all players to kill their playerObject? 🤔 Then you'll have to expect all playerObjects to die?

empty quiver May 19, 2020, 2:13 PM

#

Yeah that's the issue I'm not sure how I would make it just kill the player the player is attacking

slim ridge May 19, 2020, 2:22 PM

#

every frame too lol
the problem is that the health value is static so every time you reduce it, it's reduced for every player. So everyone with KillPlayer script has the same hp value and dies at the same time

empty quiver May 19, 2020, 2:33 PM

#

but how would I fix this?

random ibex May 19, 2020, 3:48 PM

#

You can store a key => value pair in an array

#

where key is playerid and value health

weak plinth May 19, 2020, 4:00 PM

#

uhhh .. remove static ?!?

jade glacier May 19, 2020, 4:16 PM

#

LOL

#

how to turn a static into an instance as a question indicates you REALLY should not be trying networking yet. Networking is probably the hardest part of game dev, you want a firm grasp of C# and Unity before even thinking about it.

empty quiver May 19, 2020, 4:18 PM

#

Cheers Varant

jade glacier May 19, 2020, 4:30 PM

#

Typically people just make a health component, that is tied to the Player component.

#

Assuming things other than players can have health.

#

Otherwise people often just write the health right into the player component. Though not really a great practice.

@sonic marsh Im making a 2d rpg game and is it ok if it had a generator for maps

#

its an open worldd

thats all on you, you will need to make it and make sure it syncs

#

hello

#

i have a question if i set up my mirror and its working and i release it on steam would it work?

#

@sonic marsh

#

or does steam

#

have its own network

sonic marsh May 20, 2020, 4:44 AM

#

dude thats like 1000 questions underneath

#

yes

#

but theres TONS for you to do

#

dont even worry

weak plinth May 20, 2020, 4:45 AM

#

like what?

#

xD

sonic marsh May 20, 2020, 4:45 AM

#

like get it working

#

then get your friends to try it on lan

#

then get it to work over internet

#

ect

weak plinth May 20, 2020, 4:45 AM

#

ill try lan first

sonic marsh May 20, 2020, 4:45 AM

#

steam is like the last step

weak plinth May 20, 2020, 4:45 AM

#

😄

#

@sonic marsh last question does mirror have register/login system or do i have to make my own and connect it to mirror or is it different?

sonic marsh May 20, 2020, 4:58 AM

#

not sure on that

#

probably make your own

#

again i would say that should be very low on the priority list

weak plinth May 20, 2020, 4:59 AM

#

or on steam you just have to get a username?

#

prolly the best way is upload it on steam and just give it register username thingy

#

and steam is the account

sonic marsh May 20, 2020, 5:02 AM

#

i guess

#

best way is to not have it

weak plinth May 20, 2020, 5:02 AM

#

xD

#

oh yea your right

#

but

#

they will have the same name

#

because its steam

#

@sonic marsh

#

and people dont want that

#

they want their own cool names i guessw

#

xD

So, im using an esp8266 arduino to multicast UDP packets on an ip on port 80 where its hosting a wifi server, and i was wondering how I could make unity recieve the string of data being sent over the network. Ive tried different sources, like https://answers.unity.com/questions/1406338/send-string-from-one-client-to-another-using-udp.html seems to be deprecated, and https://forum.unity.com/threads/simple-udp-implementation-send-read-via-mono-c.15900/ returns me nothing. Although the problem may be with my arduino script, which I can attatch if requested. Any information is helpfull, thanks! 🙂 (@ me if u can respond)

@weak plinth No real ideas, but maybe dont use Port 80?

its probably nothing, but just in case something else is claiming it or theres some special network rules floating around

weak plinth May 20, 2020, 7:26 AM

#

guys I have a question is it possible for the server or network to auto generate the map so that the players wouldn't generate the maps? and also delete the used map and regenerate an another map again?

#

@sonic marsh

weak plinth May 20, 2020, 7:52 AM

#

@weak plinth yes but no, you would most likely have to use procedural generation, and if you’re hosting the network on say, a chip, then it might be a bit much for the processor to handle, if not, it’s most likely probable but it will take some time for the map to generate depending on what noise you use. There’s perlin noise, simplex noise, coherent noise, etc.

#

@weak plinth yes but no xD

sonic marsh May 20, 2020, 7:52 AM

#

😛

weak plinth May 20, 2020, 7:52 AM

#

@weak plinth well im hosting the server on mirror

#

would it work?

#

xD

sonic marsh May 20, 2020, 7:53 AM

#

@weak plinth Mirror is a networking library not a host

weak plinth May 20, 2020, 7:53 AM

#

im new to networking sorry

#

@weak plinth what is procedural generation?

sonic marsh May 20, 2020, 7:54 AM

#

i highly recommend not worrying about hosting or servers or any of that, instead focus on using mirror in p2p mode, No dedicated servers (a player is your "host") and lan play only

#

that will be a MASSIVE effort

weak plinth May 20, 2020, 7:55 AM

#

Procedural generation is like what Minecraft used to make its map. It’s essentially random noise that can be used to create highs and lows on a map naturally

#

so like a seed in mc?

#

Exactly

sonic marsh May 20, 2020, 7:55 AM

#

@weak plinth Network game programming is probably one of the HARDEST forms of coding

weak plinth May 20, 2020, 7:55 AM

#

I reccomend using the accidental noise library port for unity

#

hmm thanks for teaching me cuz im dumb

#

what language

#

?

#

Here’s the library

#

https://github.com/miketucker/Unity-Accidental-Noise/blob/master/README.md

GitHub

miketucker/Unity-Accidental-Noise

C# / Unity port of Joshua Tippetts Accidental Noise Library - miketucker/Unity-Accidental-Noise

sonic marsh May 20, 2020, 7:56 AM

#

@weak plinth I've only used lib noise

#

is it better?

weak plinth May 20, 2020, 7:57 AM

#

Either one would work, but this one I think will generate the best results. There’s a few example pics I can show you.

#

is this 2d?

#

show me pls

#

📎 image0.jpg

#

That was created with the accidental noise library

#

can i create tiles with it?

#

or no

#

Absolutely, it’s just take a bit of work. I made a 2D example game with it using a tile map. I can give you the project later if you’d like.

#

yea id like to

#

very much appreciated

#

And if you’re doing a 3D game you can do that too. I spent a lot of time on the subject bc I wanted to create a terraria clone lol

#

xD

#

isnt terraria 2d

#

Yeah, but you can still make 3D games with the library.

#

Here’s a tutorial sort of explaining noise. It’s written in lua, but is still informational

#

#

well thanks but my pc cant handle 3d xd

#

(Honestly neither can mine lol)

sonic marsh May 20, 2020, 8:01 AM

#

@weak plinth Very nice, will bookmark that and read later

#

I figured i would just use lib noise for my procedural gen, nice to see what else is around

weak plinth May 20, 2020, 8:03 AM

#

Yeah, a lot of cool but under appreciated libraries out there. Lib noise is fun too though

#

@sonic marsh what language does netwoking game programming use?

sonic marsh May 20, 2020, 8:03 AM

#

@weak plinth What you should start with is either the main gameplay in a blank/simple map and get that working or networked OR start on the procedural gen and have it work off a seed (like minecraft)

#

@weak plinth ??? your using Unity right?

weak plinth May 20, 2020, 8:03 AM

#

yea

sonic marsh May 20, 2020, 8:04 AM

and i dont even know how to make music for my games

#

@sonic marsh I already know the basics i worked on some demos

hmmm its ok ill work it out

#

i have plenty of time

sonic marsh May 20, 2020, 8:09 AM

#

yup

weak plinth May 20, 2020, 8:09 AM

wow jealous 😛 i have to work so i only get like 3

weak plinth May 20, 2020, 8:09 AM

#

Thankfully there’s a lot of good networking tutorials though

sonic marsh May 20, 2020, 8:09 AM

#

yea its everywhere 🙂

weak plinth May 20, 2020, 8:09 AM

#

Pretty big subject

#

can you suggest me some

#

good

#

tutorials from it

sonic marsh May 20, 2020, 8:10 AM

#

any of the UNet ones will work

weak plinth May 20, 2020, 8:10 AM

#

oh ok

sonic marsh May 20, 2020, 8:10 AM

#

Mirror is just UNet but wayyy better

weak plinth May 20, 2020, 8:10 AM

#

Yeah Isn’t unet deprecated?

sonic marsh May 20, 2020, 8:10 AM

#

plus they probs have tons of their own now

#

yea but Mirror is basicly a open source version of it

weak plinth May 20, 2020, 8:10 AM

#

yea it is

sonic marsh May 20, 2020, 8:10 AM

#

they decided to stick to all the same ideas

weak plinth May 20, 2020, 8:11 AM

#

oh

sonic marsh May 20, 2020, 8:11 AM

#

but fixed all the issues

weak plinth May 20, 2020, 8:11 AM

#

so basically the same as unet

sonic marsh May 20, 2020, 8:11 AM

#

yea

#

but better

weak plinth May 20, 2020, 8:11 AM

#

All you need to know is:

#

Unet<mirror

sonic marsh May 20, 2020, 8:12 AM

#

😛

weak plinth May 20, 2020, 8:13 AM

#

what?

#

so do i need to learn unet

#

yea its basically the same as mirror

#

but why not mirror?

sonic marsh May 20, 2020, 8:14 AM

#

use a mirror tutorial if you find one

#

i just dont know any

#

they probably have some on their site

#

but unitys offical UNet ones will apply to mirror

weak plinth May 20, 2020, 8:15 AM

#

hmm ok thx

#

Ahh @weak plinth I finally found the one tutorial that helped me it’s here https://youtu.be/UK57qdq_lak

#

How do I set photon pun2 autocleanup to be false?

#

Anybody knows?

stiff ridge May 20, 2020, 10:48 AM

#

You can do that in the RoomOptions parameter when you create a room.

#

It's RoomOptions.CleanupCacheOnLeave = false in that case.

#

Alternatively, if only a few objects should persist, you can also use InstantiateSceneObject() on the master client (not everyone can do this, due to concurrency problems).

drifting ridge May 20, 2020, 11:24 AM

#

@stiff ridge 'RoomOptions.CleanupCacheOnLeave' was creating some bug for me a month ago so I had to set it to true. Can't remember what bug was it.
Will using InstantiateSceneObject(), keep all player game objects in room if any one of the client leaves for the remaining clients?

#

still desperately searching for a solution to 2 step oauth in unity

stiff ridge May 20, 2020, 11:32 AM

#

was creating some bug for me a month ago so I had to set it to true. Can't remember what bug was it.
you can try it again.
overall, PUN is not extremely good at passing networked objects back to the owner, should this player come back. in the mean time, the object may have moved and this is not synced yet.
we happen to work on this these days but it's complicated to get right and generic.
what's your use case @drifting ridge ? PM me, please.

drifting ridge May 20, 2020, 11:38 AM

#

@stiff ridge , ok found the bug: https://forum.unity.com/threads/weird-errors.874366/
Setting it to false solves that bug.

But I found a workaround. When the match ends, I remove all photon view components from the game objects. This prevents it from vanishing when the other client leaves.

The pic is the results ui display which is in the same scene as the gameplay. I simply move their position to a showcase position. Are there any negative implications on doing this workaround?

Hey all, new here.
Just wondering if writing a custom udp server /client is the right approach for multiplayer; do I have to use Mirror (or other services) if I know networking already?

slim ridge May 20, 2020, 6:07 PM

#

"for multiplayer" is too broad. It really depends on how clients/server interact and who has authority

cedar cloak May 20, 2020, 6:26 PM

#

public override void OnPlayerEnteredRoom(Player newPlayer)
    {
        base.OnPlayerEnteredRoom(newPlayer);

        Debug.Log("SOMEBODY JOINED");

        Debug.Log(newPlayer.NickName + "JOINED");
    }

#

I made this simple script to notify the players when and who another player enter in it

#

problem is that "newPlayer.NickName" its empty

slim ridge May 20, 2020, 6:34 PM

#

did you set it on the other client?

cedar cloak May 20, 2020, 6:37 PM

#

wym?

#

this script is in every client

#

should I first assign that newPlayer.NickName its string nickname contained in another string?

slim ridge May 20, 2020, 6:41 PM

#

Documentation states that Player.NickName is only updated when it is set. Did newPlayer's client set NickName before entering the room?

cedar cloak May 20, 2020, 6:48 PM

#

wait how can I update it before even entering the room? to you mean that I have to communicate it to Photon servers?

slim ridge May 20, 2020, 6:50 PM

#

if you dont know how to do that why are you expecting it to have a value?

#

perhaps what you're looking for is userId

nocturne osprey May 20, 2020, 7:42 PM

#

is there a better way to do 2 step 0auth with unity than embedding a browser ?

cedar cloak May 20, 2020, 7:46 PM

#

if you dont know how to do that why are you expecting it to have a value?
@slim ridge should I do something like PhotonNetwork.NickName = Launcher.myProfile.username; (aka my username string) right?

empty quiver May 20, 2020, 10:49 PM

#

@stray scroll I'm unsure what I should be looking at on this thread

amber trench May 21, 2020, 7:46 AM

#

@nocturne osprey what are you trying to use, there's no such thing as 2 step 0auth

cedar cloak May 21, 2020, 8:33 AM

#

question about Photon

#

Free version can only support 20CCU

#

doest it mean 20ccu globally per server or in rooms?

#

for ex. can I have 1 room of 20 players and other X ones waiting in the Menu?

nocturne osprey May 21, 2020, 9:42 AM

#

@amber trench there is 2 steps for a user to auth so that you can get their access token. i can't find a way to get the token from the redirect after the second screen as this action is taken in their browser

#

📎 proxy.png

#

webrequests cant complete the process

empty quiver May 21, 2020, 12:19 PM

#

figured it out cheers Jaws

wise oracle May 21, 2020, 4:07 PM

#

@nocturne osprey If configured correctly, it will redirect to the redirect URL you specified with the OAuth token

#

From that screenshot, it looks like you're redirecting to google.com instead of your own app domain or loopback url

nocturne osprey May 21, 2020, 4:08 PM

#

sorry, the redirect on that image is taken from another game that has it working. it only redirects to a URL but my problem is that I want it to redirect to UNITY

wise oracle May 21, 2020, 4:08 PM

#

How are you performing the request?

nocturne osprey May 21, 2020, 4:09 PM

#

i dont have a solution at the moment. i want to allow users to login using their twitch login

#

i cant use webrequests because of the redirect issue

#

only solution i can think of is embedding a browser which i dont really want to do

wise oracle May 21, 2020, 4:10 PM

#

Web requests can be configured to follow redirects

#

But I guess it's not an immediate redirect, it only happens after the authorization

#

Let me check on something

nocturne osprey May 21, 2020, 4:11 PM

#

yup thats exactly the problem. all the stuff on twich api documentation using curl etc is done when the access token is already known

wise oracle May 21, 2020, 4:18 PM

#

Have you considered, as a temporary solution at least, to run a web server that holds the endpoint that gets redirected to?

nocturne osprey May 21, 2020, 4:20 PM

#

yeah but that doesnt solve the problem unless i have another login system in the game too (making twitch login redundant) otherwise there would be no way to safely link the game to the webserver

wise oracle May 21, 2020, 4:20 PM

#

So you are looking to use Twitch for authentication in your game

nocturne osprey May 21, 2020, 4:21 PM

#

yeah

wise oracle May 21, 2020, 4:21 PM

#

I don't understand how that would be an issue though.

User goes to 'login'
Web server spins up with the endpoint that will get redirected to
They authenticate
Page redirects to your local endpoint
Unity can see that they authenticated and hold the token somewhere safe

nocturne osprey May 21, 2020, 4:26 PM

#

what do you mean by "Page redirects to your local endpoint"

#

cos unless its something within unity itself then there wont be a link between the game client and the web server

slim ridge May 21, 2020, 4:31 PM

#

for oauth, you need a web server to receive the request from twitch

nocturne osprey May 21, 2020, 4:37 PM

#

right but if on the server its at example.com/endpoint if i want to read that page with webrequests i can only query that url but theres no way to determine if its retrieving the collect access token (assuming multiple users)

slim ridge May 21, 2020, 4:37 PM

#

so how are you presenting the twitch login?

#

if not using browser or web requests

nocturne osprey May 21, 2020, 4:42 PM

#

ideally i would be using web requests but thats not possible because there is 2 parts of the auth process. second option would be redirect from twitch to my game which also seems not possible. that leaves requiring more input (bascially another login system) to compliment the twitch input or embedding a browser

#

i was hoping that i was missing something with oauth that would make things easier

slim ridge May 21, 2020, 4:43 PM

#

the oauth process works something like this:
user enters credentials
twitch confirms credentials
twitch redirects to the url you specified with the token in the post body or url
your application examines the redirect to obtain the token

#

it's usually possible to examine the redirect

nocturne osprey May 21, 2020, 4:46 PM

#

(non-embedded) browsers wont have access to the redirect

slim ridge May 21, 2020, 4:47 PM

#

is your app a mobile app or desktop?

nocturne osprey May 21, 2020, 4:47 PM

#

desktop

slim ridge May 21, 2020, 4:48 PM

#

I'd try to embed a browser then, and if that's not possible then create an application protocol and a small webserver to redirect to it

#

but i'd think twitch would have some library for unity that makes it easy

nocturne osprey May 21, 2020, 4:52 PM

#

hmm ill look into it some more. thanks for responding!

Hello, I would be glad if someone can help me https://forum.unity.com/threads/multiplayer-movement-lerp.895388/

slim ridge May 21, 2020, 6:53 PM

#

the problem is your BufferSize but you didnt post any code about how you calculate that value.

warm lark May 21, 2020, 7:01 PM

#

Which value ?

#

The bufferSize is just a int and I set it to 2

#

@slim ridge

slim ridge May 21, 2020, 7:04 PM

#

ok.

#

perhaps it's growing indefinitely because you're falling behind indefinitely. There's nothing here to help you catch up to the server if it got ahead.

warm lark May 21, 2020, 7:08 PM

#

Yes but I shouldn't need to catch up because I do exactly one lerp per update received

slim ridge May 21, 2020, 7:08 PM

#

could also be the fact that PositionLerpProgress is only updated when the buffer is full (BufferSize)

warm lark May 21, 2020, 7:08 PM

#

hooo

#

Let me check

slim ridge May 21, 2020, 7:10 PM

#

that makes sense actually. Every time PositionsBuffer.Count is < BufferSize a frame is basically delayed

warm lark May 21, 2020, 7:12 PM

#

yes but normaly the buffer is empty only at the beginning when im waiting at least 2 updates

#

But I need to wait for my mate to test it because I can't test it locally

slim ridge May 21, 2020, 7:18 PM

#

I'm working on something similar right now. I'm using a sequence value to keep client and server in sync. Each Update() I process enough frames to stay in sync or interpolate if i'm between frames.

warm lark May 21, 2020, 7:20 PM

#

What is a sequence value ?

slim ridge May 21, 2020, 7:21 PM

#

just a counter that goes up each frame. The server and client agree on what time to start counting and how often to count

#

If you are doing any testing in the editor, your fps might go below your PlayerPositionUpdateRate and, assuming you queue as fast as you UpdatePositionWithLerp, you wouldnt catch up.

warm lark May 21, 2020, 7:39 PM

#

It doesn't change anything because the send rate and the lerp rate are bound to Time.deltaTime

slim ridge May 21, 2020, 7:46 PM

#

assuming things stay in time.
I'd Debug.Log PositionLerpProgress and see if it ever gets above 2

warm lark May 21, 2020, 9:35 PM

#

@slim ridge I did some testing and it doesn't change anything, here is the new code ```CSharp
private void UpdatePositionWithLerp()
{
//Each frame we move toward the target position, we calculate the PositionLerpProgress based
//on the update rate, we use a buffer so the player don't stop if the packet is delayed on the network
Debug.Log(PositionsBuffer.Count);
//We wait until the buffer is full
if (PositionsBuffer.Count >= BufferSize)
canLerp = true;

if (canLerp)
{
    //If we reached our target position go to the next
    if (PositionLerpProgress >= 1)
    {
        PositionLerpProgress = 0f;
        StartPosition = transform.position;
        TargetPosition = PositionsBuffer.Dequeue().Position;
    }

    PositionLerpProgress += Time.deltaTime / (1f / PlayerPositionUpdateRate.Value);
    transform.position = Vector3.Lerp(StartPosition, TargetPosition, PositionLerpProgress);
}

}

The stranger thing is the behaviour is different if we use OpenGL or DX11 xD

slim ridge May 21, 2020, 9:36 PM

#

at least that confirms my suspicions about framerate

warm lark May 21, 2020, 9:37 PM

#

My friend has his queue empty and mine is growing

#

How would you implement this ?

slim ridge May 21, 2020, 9:39 PM

#

I'd stop tracking lerp progress.
every time you find an item in PositionBuffer regardless i'd teleport to the previous target and begin lerping to the next

#

i think you also need some code to handle when you arrive at the position before another input comes in.

warm lark May 21, 2020, 9:43 PM

#

By "tracking" you mean checking if PositionLerpProgress >= 1 ?

slim ridge May 21, 2020, 9:43 PM

#

yeah

warm lark May 21, 2020, 9:45 PM

#

How can I handle that ? because if I just stop the player it will look odd

#

that's why I try to use a buffer

#

I think you mean using extrapolation ?

slim ridge May 21, 2020, 9:46 PM

#

so your players never stop moving?

warm lark May 21, 2020, 9:46 PM

#

Yes but never stop updating even if they don't move

#

On my computer, after building and running, web requests to a VPS i own work perfectly. On other computers, certain endpoints on the VPS work while others don't. On these problematic computers, all endpoints work from an http request making program, so I figure the problem is with the code itself. I have gotten the code to produce the error: cannot connect to destination on my laptop but not on my main computer.

Hey guys, does anyone know of any game engine built on top of ECS (or ECS-like design), using fixed-point math, that supports rollback and client-side prediction ?
Pretty much Photon Quantum, but something a team of 2 developers can afford ?

#

I really don't want to roll my own, but looks like I'm out of options.

graceful zephyr May 23, 2020, 10:30 AM

#

@sacred patrol no there isn't any free/cheap option available

#

because it requires a metric fkton of work to build

#

there are a few lockstep only options for unity available on github

#

but they are all pretty subpar and i wouldn't use them for anything 'real', but maybe as something to look at and get started

@graceful zephyr Btw what's your fixed-point math library of choice ?

graceful zephyr May 23, 2020, 10:44 AM

I should have known lol

:p

sacred patrol May 23, 2020, 10:44 AM

Much to do, much to do...

graceful zephyr May 23, 2020, 10:45 AM

#

if you want predict rollback

#

none of the ones above

#

can do that (easily)

#

just building your own physics engine that's good enough for a game

#

is like a years worth of work

sacred patrol May 23, 2020, 10:48 AM

Yeah I figured. Luckily I need just the raycast alone. Something simple like casting a ray onto a straight 2d line.

@sacred patrol if you want im part of a private discord where there's a lot of talk about networking, determinism, etc.

Sure. Thanks.

If I were making a proper game that is going to market and have a budget behind it, I would seriously consider Quantum before rolling your own. The $1000 is less than you would be paying a net dev to build and maintain your own library, and it shortens the game dev time massively. The main issue would just be that your networking will get ahead of your game content. But if you want to build your own as more of a hobby or learning thing, go for it off course.

sacred patrol May 23, 2020, 11:29 AM

#

@jade glacier I know right, I would have definitely used Quantum if I had a publisher. But I decided to try and make things on my own without financial support.
So now all I have is $7000 to buy myself potatoes and pay the bills until the budget runs out. (With some passive income helping along the way)

tired raptor May 23, 2020, 11:30 AM

So currently there is no way to create a multiplayer game in unity? if I don't want to use SpatialOS or Photons - https://blogs.unity3d.com/2018/08/02/evolving-multiplayer-games-beyond-unet/ this is so confusing. What is the official unity networking framework ?

Unity Technologies Blog

Evolving multiplayer games beyond UNetUNet を乗り越え、マルチプレイヤーゲームはさらなる進化...

Through our connected games initiatives, we’re revamping how we can make networked games easier, more performant, and multiplayer-ready by default. To make...

jade glacier May 23, 2020, 11:37 AM

#

That page is kind of a running joke.

tired raptor May 23, 2020, 11:38 AM

#

Ok but its still on the official unity blog and its misleading

jade glacier May 23, 2020, 11:42 AM

#

Photon, Mirror and MLAPI are pretty commonly used. There are people using NetCode, but that requires you to go balls deep into DOTS, which is preview... So unless you are wanting to get into that, best avoid unity's networking for a while.

tired raptor May 23, 2020, 11:44 AM

#

hmm

#

And I shouldn't be using UNet, right?

#

btw Tnx @jade glacier

sacred patrol May 23, 2020, 11:49 AM

#

UNet - no. Mirror - maybe.

jade glacier May 23, 2020, 11:50 AM

#

The most correct answer is to abstract your simulation entirely from your net library. And it won't matter. But first attempts at making multiplayer are going to be an entangled mess.

#

So just do demos and quick and dirty experiments before trying anything real.

jade glacier May 23, 2020, 12:07 PM

#

When you get good at networking, you will find you have reduced your entire game to a tick based simulation that uses buffers of states and inputs, and your networking just becomes the serializing and sending one or both of those buffers to others in the form of a byte[]

#

Pun, Mirror and MLAPI automate most of that, but also as a result make it hard to avoid entangling your messaging layer with your simulation layer.

#

So you kind of just have to go make a few messes, so that any of what I said will even have meaning.

graceful zephyr May 23, 2020, 12:21 PM

#

@tired raptor that blogpost is a like...

#

yeah, a running joke in the networking community

#

they basically made a flow chart to show how much they've fucked up 😄

jade glacier May 23, 2020, 12:46 PM

#

Fucked up is generous... "up" being a positive direction. 🙂

#

"Up" might sue them for defamation of character.

#

Netcode is doing a lot right, but its at the end of a long chain of dependences on other parts of the whole DOTS strategy, so you have to dive in completely to use it.

tired raptor May 23, 2020, 1:45 PM

#

lol yeah I guess I should have figured that, the bar that indicates their progress surpasses 2022

#

Thanks guys for the clarification ^_^

Q: I am switching from photon host to photon self host, anyone know the amount of ram a dedicated server needs per player? or per 100

graceful zephyr May 23, 2020, 2:19 PM

#

@sage saffron Completely depends on your game, and what you're doing on the server

#

It's simply not possible to say "you need X mb memory per player"

sage saffron May 23, 2020, 9:21 PM

#

@graceful zephyr or someone. It is 3D fps. 40 player lobbies.

#

Just trying to get an average. I don’t want to setup a 8gb vps and it gets overloaded and the game shuts down. So if I can calculate how much ram 40-100 take by the amount of active players daily then I’d know what to host on.

#

For 3D fps, would want to know if each group of 40 took up 1gb of the vps, or 64gb of the vps.

gleaming prawn May 23, 2020, 9:29 PM

#

Do you have any idea how to make a 40 players FPS?

#

First make sure you can make your game,

sage saffron May 23, 2020, 9:30 PM

#

Each of my lobbies have 40 players

gleaming prawn May 23, 2020, 9:30 PM

#

Have you ever made and released a multiplayer game before?

#

A 40 player FPS is not so easy to make (a good one at least)

sage saffron May 23, 2020, 9:31 PM

#

I am using photons host and its plan of pay per player. Would be nice to switch to my own host. Uhh Erick that’s not helpful

gleaming prawn May 23, 2020, 9:31 PM

#

Your question sound like you have no experience with this

#

Nobody will be able to help you, sorry

#

I'm just honest

slim ridge May 23, 2020, 9:32 PM

#

you need to design, build, and test your networking solution before any benchmarking can be done.

sage saffron May 23, 2020, 9:32 PM

#

Clearly no one knows. My game works fine and is already hosted, but would like to use photon self hosting sdk

slim ridge May 23, 2020, 9:32 PM

#

1 user could take anywhere from 0 ram to 8 gigs for all we know

#

does photon have a dashboard for that?

gleaming prawn May 23, 2020, 9:33 PM

#

A 40 player FPS in photon cannot work well out of the box unless you wrote a lot of things yourself (I work for photon btw)

#

If you have, you would not need to ask this question

sage saffron May 23, 2020, 9:33 PM

#

Yes photon has its own control panel to setup on your own vps

gleaming prawn May 23, 2020, 9:34 PM

#

Photon does not expose memory usage of our own hosted clustwrs

#

If you self host, yes, you can check anything

sage saffron May 23, 2020, 9:34 PM

#

That’s why I can’t check and am asking

gleaming prawn May 23, 2020, 9:34 PM

#

Just test

#

The free self hosted license lets you host up to 100 players

#

In one machine...

sage saffron May 23, 2020, 9:35 PM

#

Before I buy a vps just wanting to know. I can test it myself yes, but maybe someone on here happen to have tested it before and would be easy to tell

#

Photon is costing me $1600/m

gleaming prawn May 23, 2020, 9:35 PM

#

Just don't ask players to host these photon servers, this would be against the EULA

#

It's is costing that much because of?

#

CCU or because you are overusing bandwidth?

sage saffron May 23, 2020, 9:36 PM

#

It’s costing that because I am paying per player

gleaming prawn May 23, 2020, 9:36 PM

#

You will still pay per player with self hosted

#

Just cheaper... But wil have to pay for the server and bandwidth yourself

sage saffron May 23, 2020, 9:36 PM

#

But it’s cheaper

gleaming prawn May 23, 2020, 9:36 PM

#

Will probably cost you more than that in total

sage saffron May 23, 2020, 9:37 PM

#

Photon has an unlimited player plan

gleaming prawn May 23, 2020, 9:37 PM

#

Unless you put the server in some crap VM, which will make the game run really bad

#

Yes, but that is just for our part

#

You need to pay for the machine and for the bandwidth in that VM

#

You should know that data, that we expose.to you (bandwidth)

#

That will cost you a lot, I guess

#

Because a 40 player game in the same room (assuming you run stock pun) uses a considerable bandwidth

sage saffron May 23, 2020, 9:38 PM

#

Photon self host for unlimited CCU is $175/m. If I know what specs I need for a vps I can add it together and see if it’s cheaper than $1600/m

gleaming prawn May 23, 2020, 9:38 PM

#

Just try it in a very cheap VM first

#

Bandwidth is expensive

#

1600 / per month is a lot of players

#

You probably have a lot of players...

#

How many CCU is that?

sage saffron May 23, 2020, 9:39 PM

#

I’ll just keep paying for photon host it’s nothing. Figured I could get it cheaper

gleaming prawn May 23, 2020, 9:39 PM

#

Well

#

There's a reason why even big companies still use.our clouds instead.of self hosting

#

Just go ahead...

#

I'll come back...:)

#

You will*

sage saffron May 23, 2020, 9:41 PM

#

Alright I’ll use it. No big deal, figured it would be valuable info to know tho. 5500 players

gleaming prawn May 23, 2020, 9:41 PM

#

The most important reasons why some companies self host are:

some security legal things, like the military
a special deal to run outside the internet, etc

#

5.5k

sage saffron May 23, 2020, 9:41 PM

#

Photon host is easier anyways lol.

gleaming prawn May 23, 2020, 9:41 PM

#

You won't be able to host that in a single server

sage saffron May 23, 2020, 9:42 PM

#

Was just curious if I could switch and how pricing would change

gleaming prawn May 23, 2020, 9:42 PM

#

You'll need at least two, setup with master server plus load balancing, etc

sage saffron May 23, 2020, 9:42 PM

#

Thanks for saying no lol. I’ll stay on photon

gleaming prawn May 23, 2020, 9:42 PM

#

You can switch, no problem

#

You don't need to change your game code, etc

sage saffron May 23, 2020, 9:43 PM

#

I tried the test on photon control panel but the stats were up and down, I couldn’t get an average

gleaming prawn May 23, 2020, 9:43 PM

#

I'm just trying to give you the reason why other companies keep hosting in our clusters instead of going self hosting

#

Btw

#

Assuming you are using pun

sage saffron May 23, 2020, 9:43 PM

#

If anyone here knew then it would be nice. It’s no problem, I can use photon website

#

PUN2

gleaming prawn May 23, 2020, 9:43 PM

#

Memory will NOT be your issue

#

The photon server process is very streamlined

#

It will not leak memory or use too much, etc... I'd say it will topically consume some 1GB or 2 at full capacity (again, assuming pun, no shitty data stored on server)

#

But at 5.5k CCU, you'll need more than one server, I assure you

sage saffron May 23, 2020, 9:46 PM

#

I planned on getting around 4

#

Depending on how much is actually needed

gleaming prawn May 23, 2020, 9:47 PM

#

You should not need 4

#

You need to read well the docs to setup the servers as a cluster

#

With the lobby/master running load balancing to distribute rooms between the game servers, etc

#

Make sure you monitor these, and so on

#

This is part.of the service we run, if course

#

Memory will not the a problem, bandwidth will, I think

sage saffron May 23, 2020, 9:49 PM

#

I can rewrite it to work as a cluster no problem, but I still would need to know what specs. I am fine using photons servers, no issues. Was just a big curiosity on if I could switch

gleaming prawn May 23, 2020, 9:49 PM

#

And VMs are much worse than the baremetal machines we use (in terms of network hardware performance)

#

As I said, machines with 8gb will Probably work, but I do not know what your game does, so this is just an educated guess, absolutely no official answer, etc

#

You should be the person capable of answering... The bare photon server uses very little ram

sage saffron May 23, 2020, 9:51 PM

#

It’s ok, you did your best. Photon pricing does not say how much ram is included.

gleaming prawn May 23, 2020, 9:52 PM

#

Because this is not something we can answrt

#

It depends on your game...:)

#

As I said, just the server would use somethi fluke, don't know, around ridiculous 40MB or so?

sage saffron May 23, 2020, 9:52 PM

#

I understand. I like the setup photon has

gleaming prawn May 23, 2020, 9:52 PM

#

But your game will push data into the server, this we cannot know

#

Room properties, player properties caches ops, etc

oblique elm May 23, 2020, 9:53 PM

Hi, I'm having a huge issue with mirror networking, I've been trying to fix it for two days now, I hope u can help me. The problem is that when I spawn the player prefab on a client, for some reason it doesn't have islocalplayer as true.
This has caused two main issues, the first one is very weird, I have an if islocalplayer, print something, and else print something else, but both prints appear in the console, and the second one, is that it won't let me run commands, so I can't to much really, plz help Ive been trying everything the hole day today and yesterday's afternoon and still can't find what is wrong.

gleaming prawn May 23, 2020, 9:54 PM

#

The running queues when handling 3k+ connections in one machine (the data for these connection queues are sent by your game)

#

For mirror, I suggest the mirror discord

sage saffron May 23, 2020, 9:54 PM

#

Erick, its alright 🙂 I understand its hard, just wanted an average for 3d fps. I have no issue with using photons hosting.

gleaming prawn May 23, 2020, 9:56 PM

#

We honestly cannot know...:)

#

A 3d FPS is not enough of a descriptuon

#

How much data do you push per.client per second?

#

How much data do you keep as player and room properties in avg

#

A regular machine, how are these srrvers you get for cheap? 8/16GB?

oblique elm May 23, 2020, 9:58 PM

#

Anyone?

gleaming prawn May 23, 2020, 9:58 PM

#

And CPU wise? You'll need to test... We are not allowed to share what is the specs we use internally... I can just say we run fully on baremetal, except for burst capacity

#

Iggy, you should ask on mirror's discord

#

They have a dedicated discord and they are cool

oblique elm May 23, 2020, 9:59 PM

#

Do u have the link?

gleaming prawn May 23, 2020, 9:59 PM

#

No, but it's on their website

oblique elm May 23, 2020, 9:59 PM

#

Ok thanks

gleaming prawn May 23, 2020, 9:59 PM

#

I guess, it's whatever is their official disxord

#

I know another company who runs self hosted photon @sage saffron

#

Albion online (mmo). But in that case it's because they do not use the basic load balancing setup + pun

#

They wrote their own server logic on top of photon server sdk

sage saffron May 23, 2020, 10:06 PM

#

Basically on my ScriptableObjects have been changed differently on the Server/Host/Client. Then when my new Client Connects, all of the ScriptableObjects are the same (the unchanged Objects, all just one object). I want the Client SO's to be the same as the Servers, how do I fix this?

slim ridge May 23, 2020, 10:54 PM

patch your clients

#

or use something other than ScriptableObjects. JSON or protocol buffers can help you there.

@dusky salmon nope, not even close

slim ridge May 24, 2020, 1:05 PM

@humble socket as far as i know, ScriptableObjects are assets and you can't really change those at runtime. If you changed them you'd have to release a new client build or build in some way for the server to provide this data to clients

dusky salmon May 24, 2020, 1:27 PM

#

@graceful zephyr Alright. Well, I'm feeling both brave and foolhardy today, so despite your warning I'm gonna give it a shot for a side project. May God have mercy on my soul.

jade glacier May 24, 2020, 1:49 PM

#

I would do tutorials for a few net libs and a junk project or two for MP before even trying to think about making a real MP game.

fair cosmos May 24, 2020, 2:02 PM

#

@jade glacier

#

i only found difficulty in networking is how to understand the topic and convert it into code

#

something like Lag Compensation or client side prediction

jade glacier May 24, 2020, 2:05 PM

#

I can't comment on whether you fully get the it or not without seeing your code or talking about it with you. But typically most first time networking attempts result in message based sync, rather than simulation based syncs. And that typically leads to a painful mess of race conditions.

fair cosmos May 24, 2020, 2:16 PM

#

ok

jade glacier May 24, 2020, 2:22 PM

#

just remember that the ultimate proper model is:
Messages <-> Tick Based Input and State buffers <-> Simulation

Messaging and simulation should never directly touch one another.

#

Proper game networking is mostly about making your simulation into something that can be networked. Messaging is just how the states/inputs that get buffered are transferred.

#

What you want to avoid is things like writing and reading messages directly to your states, or to directly trigger events. That is the path to hell.

How would u go about implementing team selecting because in my game I choose a team and when I choose a team the player is also instantiated so I cant check what team each player is on Im not sure how I could solve this issue besides assigning the teams when the player is already instantiated

spring crane May 25, 2020, 1:22 AM

#

@empty quiver Or change the spawning logic to wait until the team is known

jade glacier May 25, 2020, 1:35 AM

#

Or just modify the player object as needed (color change etc) based on the team value.

#

If the player object exists while despawned, then just use the same code that hides/limbos the player for pre match.

empty quiver May 25, 2020, 12:37 PM

#

But how do assign a certain player to a team with out assigning all the players to that team?

jade glacier May 25, 2020, 12:45 PM

#

Can't really answer that without knowing your player code, but it would just be a state (field) that gets synced for your player class.

#

Every player has an object (the actual player prefab perhaps) - and those each should have an entity ID (named differently depending on what library you are using)

#

If your player class has a field
byte team;

That would indicate the team. You would sync that value.

cedar cloak May 25, 2020, 1:22 PM

#

I was starting to learn the Photon code but I noticed that for a published game the prices for host even a little portion of players are a bit too high for an indie. What are the best alterantives that I could considerate?

jade glacier May 25, 2020, 3:13 PM

#

Depends on the game, but someone is going to want some money if they are running your server code and providing bandwidth. So you mostly have to sort out cloud vs hosting with a metal box vs whatever else based on your game first.

#

If it needs a Unity instance to serve its going to get spendy.

#

I wouldn't really recommend trying to do MP as an indie without some funding. All avenues cost money, and you don't want to be making game design choices around short term cheap thinking. Successful MP games are going to need budget, since MP is only good if you have a player base, and player bases cost money to get.

weak lava May 25, 2020, 4:13 PM

#

Hi, do you usually use a heartbeat also to determine ping ? Or rather having a heartbeat to determin that the connection is still alive and a ping/pong just for rtt ?

jade glacier May 25, 2020, 5:06 PM

#

I personally use consumption/apply time for my RTT calculations, assuming you have a full round about path to clock like that.

#

You need to know where RTT is measured, so you can factor in the various buffers yourself - if you are going for as accurate as possible.

#

Interpolation adds latency, transport buffers add latency, and frame buffers can add latency.

#

If you are tick based, you can just piggyback your ping calcs on your ticks. Otherwise... whatever works.

#

Though if you are tick based, the use of RTT kind of vanishes, since everything is already tick based rather than time based.

#

So the short answer is - totally depends on what your system is currently.

Best to post your question, doubt anyone will PM you without some idea of what they are getting into.

fading radish May 26, 2020, 1:00 PM

Okay so I'll try to keep this short. Basically I'm working on a First Person Shooter and the multiplayer works via PhotonNetworking. Everything works fine, everything's synched and I was able to playtest with some friends of mine. The next day I made some progess and added a few features but didn't touch the networking at all. Not a single line of RPCs was changed, nothing connected to the Multiplayer System was added. Then I built the whole thing and tried to play with my friends again but it didn't work. I wasn't able to join them, they weren't able to join me. But here comes the fun part I don't understand. They can join eachother and I can also join them but only if I use the Unity Editor or a development build to play. It doesn't work as long as I use the same .exe file they use

jade glacier May 26, 2020, 1:09 PM

#

Check your regions

#

Using the latest Pun2?

#

Dev Region was added so you can force a region for all development builds, that ensures everyone connects to the same continent server.

#

@fading radish

#

Dev Region might be in your current version, which would be why development builds were working for you.

#

Once you build a release, you might all end up in different regions

fading radish May 26, 2020, 1:12 PM

#

yep, current Pun2 and I already checked that, we're all playing on eu servers, even if I don't force the game to

jade glacier May 26, 2020, 1:12 PM

#

You put eu into the FixedRegion field?

#

Not sure then, sounds like a version issue yeah - if you are all on the same region

#

Might be more of a @stiff ridge question if its not region related.

fading radish May 26, 2020, 1:13 PM

#

i tried both, with and without the fixedRegion setting. We're always connecting to EU

#

Super weird. Thank you anyway

#

I mean as long as it's working for everyone else that's fine - I can always use a development build - it's just bothering me that I can't figure out what's causing it 😅

jade glacier May 26, 2020, 1:15 PM

#

You may have found a bug, so would be good to isolate it.

fading radish May 26, 2020, 1:17 PM

#

I will test it again today, once my mates are awake. Maybe it was just some issue on my PC that got fixed by restarting. Yesterday I tested it with multiple different groups and it always worked perfectly for them, so it probably is something local

jade glacier May 26, 2020, 1:18 PM

#

Might be worth a rebuild of the project or something before getting too far down a rabbithole yeah

stiff ridge May 26, 2020, 2:28 PM

#

So, you need to use the same GameVersion string, pun version and the same region.

#

After the Editor connected to the Cloud for the first time, the "Dev Region" gets set and is used in all Development builds. You can either build release or master or you can just clear the "dev region" in the PhotonServerSettings (make sure there is only one file of that name).

#

You could use a fixed region as well. It will override the Dev Region (as it's more specific).
If they got a release build but you are in the Editor, your Editor will still use the Dev Region (again: if set and if you don't use a Fixed Region).

#

Alternatively, clear the dev region and fixed region values and use the Photon Dashboard (webpage) to set which regions are allowed for "best region" selection. This is the most flexible definition, as you can change it anytime (not in the build).

fading radish May 26, 2020, 6:56 PM

#

@stiff ridge thanks alot for taking the time and answering that detailed. Turns out there really was something wrong on my end... I just got to test it again and now everything seems to work..

#

But I have a ragdoll problem. I activate it whenever a player dies and on his own screen everything is fine (as in he just falls to the ground - like he's supposed to). On everyone elses screen, he starts sliding in a random direction. I tried giving the main collider a high friction value but that's pretty much all I can think of right now. Anyone who has a better idea?

what's the easiest way to have multiplayer where players can start servers from the game and others can join (I'm extremely new to networking)

fading pawn May 26, 2020, 9:12 PM

#

There are a lot of PUN resources and videos for new devs

stiff ridge May 26, 2020, 9:20 PM

#

@fading radish, I can imagine that your character is still sending updates, even when you turned it into a ragdoll. On remote clients, the position updates will not perfectly align with the ragdoll solution locally and could cause unwanted movement. Incoming updates and local values will collide and "fight". I would not send position/animation updates for a ragdoll. You can send a flag telling everyone remote to set the character to ragdoll and use the local pose.

fading radish May 26, 2020, 9:24 PM

#

@stiff ridge that's exactly, what i'm doing. The Player has a ragdoll object attached that gets activated whenever someone dies and the "normal" player object gets deactivated. That (de-)activation is the only thing I send over the network

stiff ridge May 27, 2020, 8:06 AM

#

@fading radish , hmm, then I don't know what's up. If you don't sync anything else (neither transform, nor animation), it may be something sneaky. I guess you set the remote player's character to IsKinematic? Maybe this? Or maybe some settings on the colliders? Some component being disabled instead of enabled?

fading radish May 27, 2020, 8:10 AM

#

They are two seperate objects. The character as the ragdoll in a T-Pose, and the actual chatacter. The character model + collider gets completely disabled, the ragdoll + colliders get activated. I don't activate any other components manually. Also, If it was a wrong setting concerning the colliders (or anything along those lines) wouldn't the sliding also happen on your own screen? It happens 100% of the time when you kill someone else, but 0% of the time when you see yourself die. It has to be connected to networking :(

stiff ridge May 27, 2020, 8:21 AM

#

Hm. You make it sound as if it could not be related to the networking but then again .. it only happens for remote characters.

#

Does the ragdoll even have any networking objects on it? Is it parented to some object (that's networked)?

fading radish May 27, 2020, 8:50 AM

#

yes, so I have a Player Prefab, that gets instantiated everytime a player joins. That prefab has a few childs - the cameras, the Character standing up, the Character crouching (temporarily until i get to do animations), the ragdoll, a ground detection object and a text field (to display the username). The whole Player object itself is being synched

I'm using PUN2 Photon, and I'm trying to use a Photon Transform View to network position and rotation easily.

I've used Photon Transform view before on my player and enemies in another project, so I'm familiar with it's workings. This time however, for some reason, Rotation is being correctly transmitted, but NOT position: I want position networked, but it is not affecting the position of the enemy for some reason...? There are no errors either.

Any ideas why this may be? Why would rotation work fine, but position silently not work?

decrease physics timestep, use raycast

marsh bison May 29, 2020, 8:01 PM

#

@slim ridge I'm sorry, how do I "decrease physics timestep", and how would raycasts help? Should I lower the "Fixed Timestep" in Project Settings -> Time from .02 to .01?

slim ridge May 29, 2020, 8:06 PM

#

yeah, lower the fixed timestep is what i meant, it will cost more cpu but trigger will be detected better. the faster objects move the less effective colliders become and more effective raycasts become

#

with a raycast you can basically "look ahead" of the bullet for incoming collision

#

so instead of moving most of the way through a collider before triggering you can calculate the exact time it would hit

marsh bison May 29, 2020, 8:58 PM

#

@slim ridge I changed the Fixed Timestep from .02 to .001 and noticed no difference. Could you please recommend some resources about raycasting to improve collision detection in a way that works with Photon 2?

slim ridge May 29, 2020, 8:58 PM

#

im not sure how it would work with photon 😦 maybe the photon guys in here can help 👀

marsh bison May 29, 2020, 9:03 PM

#

@slim ridge The OnTriggerEnter2D should work to detect collisions, but there is some sort of problem that arises from the networking aspect. Thanks for your help. Perhaps I should use raycasts anyways even though it would not fix this problem.

#

Does anyone else have an idea why OnTriggerEnter2D would not work with Photon 2?

hollow nymph May 29, 2020, 9:22 PM

#

Trigger is not guaranteed to be triggered if your object is moving too fast

#

You should never rely on it for this kind thing

#

Had better use raycast or manual math calculation

marsh bison May 29, 2020, 9:53 PM

#

@hollow nymph It always gets triggered, but it triggers later than it should. Would raycasts still help?

@spring crane Is there a better way to handle when the bullets hit the players?

spring crane May 29, 2020, 10:21 PM

#

Yea I generally use Raycast/RaycastAll from previous position to current position

marsh bison May 29, 2020, 10:24 PM

#

@spring crane Would that fix the problem of the bullets going past the players before registering a hit? I would think that raycasts would only help if my problem was that the bullets were going through the player, never registering a hit.

spring crane May 29, 2020, 10:28 PM

#

Depends how severe penetration is and what problem you are exactly trying to solve

#

Cast won't hit anything if the position isn't inside of the collider already

#

@spring crane I posted a video of my problem above.

spring crane May 29, 2020, 10:35 PM

#

Are you destroying it over the network?

marsh bison May 29, 2020, 10:55 PM

@spring crane Yes, but it is not destroying bullets that is the problem. The health decrease happens at the same time as the bullet disappears, long after the bullet first touches the player.

Whatever you are doing for networking, its terribly wrong @fading radish

worn wolf May 30, 2020, 3:48 AM

#

Guys I heard it's better to have your game server running multiple processes so that if one crashes the rest remain functional, and have a main process which monitors them all and reboots them if they crash.
Thing is, how would the processes communicate and share data between eachother to keep all players in sync? And how would they all run on the same port?
I'm just speaking out of curiosity btw, not working on any project involving this at the moment.
Please ping me if you have an answer.

spring crane May 30, 2020, 4:48 AM

#

Depends on the game, but often you can logically separate processes by matches

#

Communication can be done through networking layer, especially since the watching process could be on a separate machine, and the server processes grouped on separate machines

hollow nymph May 30, 2020, 5:26 AM

#

@fading radish you must have 2 things modify the transform, your networking logic is incorrect

#

Like you have the server sending the player update position, then locally, the client run the physics simulation, then they are both modifying the position

#

If you are using Photon or Mirror(the preferred one), you can just use the built in sync transform, both are good

@hollow nymph I just got myself into unity like 5 days ago, so I would need some more help 😅 I can't seem to figure out what could cause the problem you described. Currently I have a player prefab, that gets instantiated whenever you join the game. On there I have two Photon Views - one for the Photon Transform View (is that what you meant?) and one for the player script to sync stuff like the current weapon. Even if I remove the Player Script from the Views, the "stuttering" still happens, so I'm a bit out of ideas. It also happens in the air, so it's probably no collider issue, considering there's only one collider active at any given time, besides the rigidbody there's no physics involved.. I am confusion

spring crane May 30, 2020, 12:43 PM

#

I don't think you should have multiple views on the same object 🤔

hollow nymph May 30, 2020, 12:44 PM

#

@fading radish did that happen on both the server and the clients? the stutter

fading radish May 30, 2020, 12:44 PM

#

yes. Sometimes it's worse and sometimes it's not as bad but it always happens for everyone

hollow nymph May 30, 2020, 12:45 PM

#

it's strange if it happens on host (Master Client), because host does not need to use network to sync himself under the hood

#

so if you host (server) is stuttering, I think it can't be networked problem.

fading radish May 30, 2020, 12:47 PM

#

But if that was the case, wouldn't it also happen with your own player on your own screen? If I turn the first person camera into a third person one, it's only the other player that's stuttering

hollow nymph May 30, 2020, 12:48 PM

#

so you are fine locally?

#

your own local player is good, but you see other stuttering

fading radish May 30, 2020, 12:49 PM

#

That's what was happening two minutes ago, yes... Now I reset the Photon View and just added the Scripts again. Suddenly I can't reproduce the stuttering anymore.

#

nevermind, it's back, but now it's like you said, the host doesn't have stuttering, the client does

hollow nymph May 30, 2020, 12:51 PM

#

if the client is not moving, the host shouldn't see him stuttering, right?

fading radish May 30, 2020, 12:54 PM

#

The stuttering also occurs when the other player isn't moving at all. I just realized, that the transform is constantly changing, even without any input. If I freeze the position in the rigidbody and then unfreeze it, the stuttering stops until the player dies/respawns

hollow nymph May 30, 2020, 12:56 PM

#

good, then it's not network problem

#

it's unity problem

#

something in your code is wrong

#

you have to find out who is modifying your transform.position, do you set your rigidbody as kinematic?

fading radish May 30, 2020, 12:57 PM

#

no, it's not kinematic

hollow nymph May 30, 2020, 12:57 PM

#

you have to set it as kinematic

#

if you want to control the position by yourself

#

or set transform.position

#

otherwise, it will be simulate by the physics engine and the transform.position will be updated by the physics engine inside Unity

fading radish May 30, 2020, 1:00 PM

#

But I control the player by creating a vector depending on the inputs, multiplying it by the speed and applying it as velocity to the rigidbody. That won't work if I set it as kinematic, right?

hollow nymph May 30, 2020, 1:03 PM

#

but does your floor also has collider/ rigidbody which will collide with your player?

#

I think the problem is , you should not use isKinematic = false, to design your controller. because under Unity's physics simulation, a lot of things will happen (coliision) + gravity , and your character can't be controlled properly by the input

#

there's gravity problem too

#

there's built in character controller just called "Character Controller" component

#

it might be better to use that

#

or you have to design yours by modifying transform.pos by yourself based on input

fading radish May 30, 2020, 1:09 PM

#

Yes the floor is a simple plane with a box collider (rather than a mesh collider since players used to fall through the ground if they fell too fast)

#

alright, I was afraid that this could take some time to fix 😁 I will take a look at the character controller and if I'm able to implement it without destroying all the other code I have. Thanks for the help 🙂

@bitter forge Mirror

#

Because in Mirror you have full independent, and in photon u are dependent

bitter forge May 30, 2020, 4:23 PM

#

Alright thanks

Say I wanted to have some logs for diagnosing whether someone using hacks (speed hack for example), should I log their position in database whenever they move? Or would this be inefficient, I could see the database filling up pretty quick if I did that.

slim ridge May 30, 2020, 7:21 PM

#

If you are concerned about hacking you should give your server authority over positions. It can examine each one and enforce the rules without the need of a database.

jade glacier May 30, 2020, 8:00 PM

#

A database is definitely not the way. I wouldn't concern myself with defending against hackers until you have completed some basic proof of concepts and tutorials. Networking is hard enough without trying to tackle hacking right out of the gate.

How are people handling NAT traversal/punch through/port forwarding for when players self host?

gleaming prawn May 31, 2020, 8:57 AM

#

Photon bolt does the custom signaling via the room, uses standard stun messages/protocol for reflexive address lookup and handshakes...

#

So, STUN (which specifies you need a signaling mechanism). You can also use steam transport layer, something like that...

sonic marsh May 31, 2020, 10:20 AM

#

@gleaming prawn Sweet, ive seen that STUN thing while researching, not to sure I understand it but ill keep reading

fair cosmos May 31, 2020, 3:04 PM

#

I always ss some good things as u explain above @jade glacier

#

what does this means writing read message directly to your states?

jade glacier May 31, 2020, 3:21 PM

#

You have to first have buffers in place and reduce your simulation to states and ticks... otherwise that has no meaning. @fair cosmos

fair cosmos May 31, 2020, 3:21 PM

#

for example? send data only in time like 20 packets per second?

slim ridge May 31, 2020, 3:22 PM

#

i think he means make sure your simulation has authority over time. (when to change state, when to trigger event)

fair cosmos May 31, 2020, 3:22 PM

#

i nvr have used buffers

slim ridge May 31, 2020, 3:22 PM

#

without that it's like a car with two drivers :S

jade glacier May 31, 2020, 3:22 PM

#

It is too large a question sorry. If you aren't familiar with the concepts of simulation and state ticks, the rest is going to have no meaning.

fair cosmos May 31, 2020, 3:22 PM

#

@slim ridge it makes sense

jade glacier May 31, 2020, 3:22 PM

#

You should research a bit on how most games deal with simulation

#

Counter-Strike GO is a pretty common reference, but most game networking discussions talk about simulation and tick.

#

Once you reduce your game to tick based states/inputs.... those go into your buffers (history)

#

It is that numbered history that you are syncing, not the state themselves.

fair cosmos May 31, 2020, 3:24 PM

#

right!

jade glacier May 31, 2020, 3:26 PM

#

Ticks are no the same as time btw

#

The specific example of doing it wrong is

if (hasAuthority)
    RPC(myPosition);
}

RPC(Vector3 pos){
   transform.position = pos;
}

That directly connecting the messaging to the state.

fair cosmos May 31, 2020, 3:33 PM

#

@jade glacier so i am totally wrong doing my game networking

#

and what can be the right?

jade glacier May 31, 2020, 3:34 PM

#

All beginners are, that is why first attempts at networking should be considered learning tests.

fair cosmos May 31, 2020, 3:34 PM

#

yeah, atleast i came to know that i am doing wrong

jade glacier May 31, 2020, 3:34 PM

#

Right is to capture your inputs and states on a tick, and sync buffers, and consume from those buffers.

fair cosmos May 31, 2020, 3:34 PM

#

if(_timeSpend > syncInt){
if (hasAuthority)
timespend = 0;
    RPC(myPosition);
}
}

RPC(Vector3 pos){
   transform.position = pos;
} ```

jade glacier May 31, 2020, 3:35 PM

#

If you need more details you have to go internet for that. I don't have the 3 hours required to give a proper course on good networking here every time someone asks about this unfortunately.

fair cosmos May 31, 2020, 3:35 PM

#

any course?

jade glacier May 31, 2020, 3:36 PM

#

nope

#

networking is not for anyone wanting easy.

#

You have to become an expert, or accept that you will be making mediocre networking and just do it wrong, or use a full stack like Bolt.

fair cosmos May 31, 2020, 3:36 PM

#

i am using Mirror!

jade glacier May 31, 2020, 3:36 PM

#

Networking is one of the harder parts of game dev, and Unity gives nothing for tools at the moment outside of the preview netcode.

fair cosmos May 31, 2020, 3:37 PM

#

and i do not want to use that netcode

jade glacier May 31, 2020, 3:37 PM

#

Mirror has no concept of simulation, you are on your own there. Mirror is a messaging layer and an entity lifecycle layer.

fair cosmos May 31, 2020, 3:38 PM

#

well i love mirror because as u said you are on you own there we are not dependent on it, we can do whatever we want

jade glacier May 31, 2020, 3:39 PM

#

Just be aware that it will encourage the bad behavior of tying messaging directly to your states.

#

You have to make your own tick engine if you want to make a proper tick-based state sync.

#

Or don't, you can ignore that and just write directly to the current state. You will just have a mess of race conditions to deal with, and internet jitter/noise headaches.

#

But it will "work"

fair cosmos May 31, 2020, 3:40 PM

#

well i will look into that

#

What about communicating directly with .net sockets instead of using hlapi?

#

u may have seen TOm Weiland videos, he is making tut on this!

jade glacier May 31, 2020, 3:41 PM

#

Unless you create a tick engine and ring buffer... there is no "easy" way to do it right.

fair cosmos May 31, 2020, 3:42 PM

#

ok

jade glacier May 31, 2020, 3:42 PM

#

Photon Bolt does it correctly. You can do a tutorial for that to kind of see it in action to get the concepts involved.

#

Or just don't bother, and just do it all with messaging and call it good enough.

#

But you can't just fix that once you go that route. Proper networking starts with the simulation and buffers... messaging comes last. Mirror/Pun/Unet/MLAPI all put messaging first - so you are going to likely need to start over once you decide to do it right with any of those.

fair cosmos May 31, 2020, 3:48 PM

#

ok thnx!

I'm trying to implement the team mechanic still I've managed to make it so the first player who spawns are assigned to the correct team so they respawn but when people joined the variable isn't changed, I'm using "PV.isMine" to make sure I'm changing for the right player but for some reason the function is always false when a new player joins

@stray scroll their netcode thing

#

is such a fucking mess lol

#

2 years of 'talk' and 'pr management' about how bad the situation is

#

and still nothing usable

#

my dots networking lib i made works better than the built in one, without any code gen or any other crap they have

#

it doesnt suffer from cpu issues with delta computation

#

has individual priorities for entities

#

and is very bandwidth efficient, etc.

#

and i built that in what 3-4 months? they've put out something "somewhat broken and not done" in 2 years

#

what a joke

#

Oh and they made a new survey

#

What happened with the results from the old survey?

I need some help from anyone willing to think along with me.
I have a project that used to run fine, but the communication with the server stopped working.
The weird thing is, it DOES work when I open Fiddler to debug network traffic, but when I close Fiddler it stops working
I'm stumped.

brazen ridge Jun 2, 2020, 4:04 PM

#

Anyone? I have no idea what's going on

slim ridge Jun 2, 2020, 4:07 PM

#

what have you done to debug the issue?

brazen ridge Jun 2, 2020, 4:11 PM

#

Looked at server IIS logs, send debug messages via Postman, tried debugging with Fiddler but you can see how that went.

#

It works in the Unity Editor

#

But all the latest version of our app that are publicly available stopped working

slim ridge Jun 2, 2020, 4:13 PM

#

[] is the server sending data
[] is the client receiving data
[] is the client sending data
[] is the server receiving data

where does it break down?

brazen ridge Jun 2, 2020, 4:14 PM

#

it works when Fiddler is open, so I'd say sending?

#

wait no... I have no way of confirming what is going on since I can't recreate it with Fiddler open

slim ridge Jun 2, 2020, 4:15 PM

#

do it with logs

brazen ridge Jun 2, 2020, 4:15 PM

#

The logs on the server aren't showing my activity

#

It doesn't show my attempts to log in with our app at all

slim ridge Jun 2, 2020, 4:16 PM

#

is the client attempting to send the packets?

brazen ridge Jun 2, 2020, 4:16 PM

#

it should, but I can't confirm it because turning on Fiddler "fixes" the issue

slim ridge Jun 2, 2020, 4:16 PM

#

use a log

#

i'm hoping you'll find that it's not attempting to send them and you can fix it easily. otherwise there's some issue in the transport layer (i think that's the right layer, could be wrong)

brazen ridge Jun 2, 2020, 4:18 PM

#

yeah, but the fact that opening fiddler "fixes" it seems to point that it's somewhere outside of Unity...

#

I talked with someone else who pointed out that Fiddler uses it's own root certificates for communication

#

Also, the Android version of the same build doesn't have the issue

#

But I'll see what I can bring up with logs.

#

But if anyone has any tips based on the above, please leave a ping

slim ridge Jun 2, 2020, 4:35 PM

#

check your server at OS level it's probably rejecting due to certificate

trying to do a simple networked test on Oculus Quest and when i do a build, its failing to find and connect to the server. this works fine in the editor and the Quest is connected to the internet through the same wifi as my Unity computer. are there any special permissions I need to add to android player settings? This is the first time I've tried any kind of networking in a Quest build. I already tried setting "Internet Access" to "required" in the player settings...

Hi folks, I have been away from Unity for a bit and I looking through options for networking in Unity. Last I heard Unity was in the middle of rewriting their entire networking structure? I am looking at a few different options for networking frameworks like Mirror, Photon, etc. Any other big ones now?

gleaming prawn Jun 3, 2020, 1:04 PM

#

Photon Quantum (I'm one of the developers) has been released 2 years ago.

jade glacier Jun 3, 2020, 1:04 PM

#

Photon is 3 (4) libraries, but those are the places most people start these days.

gleaming prawn Jun 3, 2020, 1:04 PM

#

Unity itself still in promiseland

jade glacier Jun 3, 2020, 1:05 PM

#

Mirror is there same architecture as unet

#

I think when most people say photon here, they mean PUN. But there is Bolt and Quantum that are also photon libraries. @lone jackal

lone jackal Jun 3, 2020, 1:08 PM

#

this is great info, ty folks 🙂

jade glacier Jun 3, 2020, 1:09 PM

#

Mirror, bolt, pun, and quantum are all wildly different. So it's not just 'pick one'

#

You need to pick based on your game type, and whether you want a complete stack, or just a messaging/entity layer.

#

Quantum is the major outlier, and is the flagship product for photon. It's a deterministic engine.

lone jackal Jun 3, 2020, 1:13 PM

#

Yeah, I plan to dig deep in each to see how I can mesh with them. Right now I am researching scalability. I am working with a few options for integration into Kubernetes and I love DevOps and things of that nature :). Atm I have some work done with websockets and scaling in k8s.

#

I am working on a bit of research for marrying DevOps and Game Development, normal apps are boring 🙂

gleaming prawn Jun 3, 2020, 1:18 PM

#

I am working with a few options for integration into Kubernetes and I love DevOps and things of that nature
With Photon you do not deal with this, unless you work with us...:)

#

If your goal is to release the game, that's actually one less thing to deal with

#

Except if you plan to host dedicated Bolt servers, then you may do that

#

If your plan is to develop/release a game, that's normally the last of your worries.

#

Although the COST of it should be considered

lone jackal Jun 3, 2020, 1:24 PM

#

yep, that is where a lot of my focus is

#

containerization of unity and friendliness of the networking framework to scaling

#

so it can scale and not cost a ton

#

ideally though unity is not running at all in a container, and it's a dedicated server, but that would obviously start requiring things like physics engines on the server side

gleaming prawn Jun 3, 2020, 1:28 PM

#

When you want traditional dedicated server you are normally talking about a Unity (or game engine in general) instance...

#

Which is NOT what you want when cutting costs is one of the goals..

#

No matter how well you spin up servers, they will cost A LOT

#

The point is, this is not really the only way to do accurate and reliable multiplayer...:)

lone jackal Jun 3, 2020, 1:29 PM

#

I wonder what is Unity's base resource usage is in a headless state though?

gleaming prawn Jun 3, 2020, 1:30 PM

#

Well, just running full game sim with physics is already a lot...

#

Whatever engine you get, if you run full sim on server you can never compete with a server that only handles input batching and control (where you can defer game validation based on automated replays)

#

We're always talking about 10x/100x more scalability... But... Whatever...:)

lone jackal Jun 3, 2020, 1:31 PM

#

yep yep exactly

gleaming prawn Jun 3, 2020, 1:34 PM

#

Mirror/Bolt are both bases on a Unity instance being the host (either listen server or dedicated headless)

#

Bolt comes with punch through + relay connection (through photon room). Mirror AFAIK works out of the box on LAN only... Or dedicated server... Unless they've added default support for punch, etc

#

Quantum is a deterministic game engine, so totally different approach.

#

PUN is relay based only

jade glacier Jun 3, 2020, 1:38 PM

#

The correct answer for most people is Quantum, but it isn't really accessible to hobbyists.

gleaming prawn Jun 3, 2020, 1:38 PM

#

Easier to start with (PUN2)

jade glacier Jun 3, 2020, 1:39 PM

#

Disclaimer - I work on the Pun2 team, though not sure a disclaimer is needed when I'm not actually pushing it. 🙂

#

Of all of the engines discussed, I believe Pun has the largest current number of games using it. But it does have caveats. Relay based state-sync and interpolation means lots of client authority, and no inherent lag compensation of any kind.

burnt sparrow Jun 3, 2020, 1:53 PM

#

you can add Epic Online Services to the above
people aren't used to it yet so nobody's sure how well it works (probably very well)

gleaming prawn Jun 3, 2020, 1:54 PM

#

Epic Online Services is to compete with Playfab and Steam (services) AFAIK

#

It is not at all for (online multiplayer) Gameplay implementation...

#

UE Networking is (lets say similar/equivalent in some aspects to Bolt and to some extent Mirror, but of course for people using UE)

burnt sparrow Jun 3, 2020, 1:56 PM

#

mm yea it's more backend , transport is prob not part of it

gleaming prawn Jun 3, 2020, 1:56 PM

#

not at all

#

Although they wanted to add a relay service to it at some point (similar to what steam offers)

#

Not sure if they ever added

#

But a general transport layer is not really a deal-breaker since at least 10-years... this is pretty much settled
