None that I know of. There are plenty of framework to choose from (both free and paid) but there is no silver bullet and games are so different that it's almost impossible to make a general purpose framework that won't put limits on you

spring valley Sep 28, 2020, 7:47 AM

#

any suggestion on playfab or gamesparks and why people are instead approaching pun / miror more

shut yarrow Sep 28, 2020, 7:48 AM

#

PUN isn't authoritive at all and perhaps one of the easiest networking solutions for beginners

#

I never tried mirror so can't say anything about that

spring valley Sep 28, 2020, 7:48 AM

#

what would you suggest if i wanna get into sever based games like dedicated server handling all game logic

#

any DIY for that

#

becase i dont really feel pun and mirror will help in a long run

shut yarrow Sep 28, 2020, 7:49 AM

#

There are but I'm not sure that you're ready for that task yet and it's going to be frustrating

#

It requires you've done quite some research already before you can try to make something useful

#

I'm using an 'easy' option but it also means I have to do almost everything myself

#

If you're interested to find out, look into ENet

spring valley Sep 28, 2020, 7:51 AM

#

i am willing to do the dirty work if it helps in long run

shut yarrow Sep 28, 2020, 7:51 AM

#

How much experience do you have with networking and programming in general

spring valley Sep 28, 2020, 7:51 AM

#

networking not much that is why i am willing to learn it but with programming lets say 5 years

shut yarrow Sep 28, 2020, 7:52 AM

#

You at least need to have good programming knowledge

spring valley Sep 28, 2020, 7:52 AM

#

i know c, c++, c# , python pretty well

#

weak networking guy u can say

#

xd

#

thought i have made games with firebase and unity

shut yarrow Sep 28, 2020, 7:53 AM

#

That'll help though, but networking is something really specific so it's not something you can just do on intuition

spring valley Sep 28, 2020, 7:54 AM

#

tbh i have my game down so if i can get my hands on a part where i can have dedicated server and i can use them for my game , it would be really good

#

i am willing to learn

#

i think networking may be the only part putting me down as a programmer hence i wanna get that up

shut yarrow Sep 28, 2020, 7:55 AM

#

You can, if you think you can learn a new framework that doesn't have so much documentation but you know how to use the few simple mechanisms

#

I haven't found any simpler option than ENet yet, that's why I like it so much

gleaming prawn Sep 28, 2020, 7:55 AM

#

Tip #1 to design networked games:

it's about how you control the simulation, not about how you send data

spring valley Sep 28, 2020, 7:56 AM

#

i have always wondered how these games like fall guys, among us store data in networking scenarios

#

knowldege on that would be damn returning\

gleaming prawn Sep 28, 2020, 7:56 AM

#

Start thinking how you would design a synced mechanism so all machines are "aware" of a "tick", and everyone simulates around that tick.... and everything you send/reconciliate is tied to that tick rate

shut yarrow Sep 28, 2020, 7:57 AM

#

With ENet you don't worry about how to send data, that;s what the framework does for you. You worry about your packet structures and your networkingloop

gleaming prawn Sep 28, 2020, 7:57 AM

#

Among Us is RELAY, it's a DIY version of something like PUN

#

networkingloop
That's the ticker... But it's more than just networking

#

It should drive how the simulation runs

#

I can't say about the other tools that I'm not familiar with, but these from us use this principle:

Photon Bolt
Photon Quantum
SNS (PUN2 add on by @jade glacier )

shut yarrow Sep 28, 2020, 8:00 AM

#

If you want to try ENet, you can use either C# or C/C++ with it so that is nice, and it's very lightweight as well

spring valley Sep 28, 2020, 8:00 AM

#

is it scalable?

shut yarrow Sep 28, 2020, 8:01 AM

#

Yes

spring valley Sep 28, 2020, 8:01 AM

#

also, is among us server based or client based?

shut yarrow Sep 28, 2020, 8:01 AM

#

Because of its simplicity and being very lightweight on memory there's a lot of room to scale

#

A guy made a video using DOTs and ENet with a simulation running 5000 clients or so

#

That's pretty decent for a single server instance

spring valley Sep 28, 2020, 8:02 AM

#

DOTS

#

IS

#

DAUNTING

#

in the state it is right now

shut yarrow Sep 28, 2020, 8:03 AM

#

Yeah but just to give an idea of what's possible

#

It's in general not the networkinglibrary that is the problem, more like how you handle your business with it

spring valley Sep 28, 2020, 8:03 AM

#

just for the sake of networking i have even thought of switching to unreal engine

#

unity feels like beta

gleaming prawn Sep 28, 2020, 8:03 AM

#

DOTS is in preview, not complete, not in a usable state right now... Cool to learn though

spring valley Sep 28, 2020, 8:03 AM

#

in this sector

shut yarrow Sep 28, 2020, 8:04 AM

#

Don't rely on built in networkingsolutions

gleaming prawn Sep 28, 2020, 8:04 AM

#

Depends on what you plan...

#

Don't rely on built in networkingsolutions
You mean Unity's?

shut yarrow Sep 28, 2020, 8:04 AM

#

For example, great example as well 😛

spring valley Sep 28, 2020, 8:04 AM

#

unitys not good

#

fall guys uses this thing called multiplay

gleaming prawn Sep 28, 2020, 8:04 AM

#

The new one has good foundations, but like everything dots... Not interesting at all yet

spring valley Sep 28, 2020, 8:05 AM

#

though multiplay is not transparent

#

kappa

gleaming prawn Sep 28, 2020, 8:05 AM

#

Multiplay is just server hosting

shut yarrow Sep 28, 2020, 8:05 AM

#

My point is, the engine makers are focused on offering features, not really specializing in some specific field like networking so I'd rather get a solution made by people who put all their time in the product they work on

gleaming prawn Sep 28, 2020, 8:05 AM

#

Nothing to do with networking SDK

#

Swanson. the UE networking is decent (not perfect, but decent)

shut yarrow Sep 28, 2020, 8:06 AM

#

Maybe you're right and I wouldn't doubt your word on that

spring valley Sep 28, 2020, 8:07 AM

#

also, why dont people here suggest playfab or gamesparks?

shut yarrow Sep 28, 2020, 8:07 AM

#

I never tried UE it doesn't even run on my hardware

#

But to choose an engine just because of the networkingsolution is also bit strange to me

gleaming prawn Sep 28, 2020, 8:07 AM

#

playfrab or gamesparks?
We do suggest that, but that is NOT networking SDK

#

These are player-profile DB services

#

Playfab is decent, and has been a favorite choice by most of our customrs.

#

You can also run your own solutions, etc

#

But they are NOT a networking SDK... They have some very RUDIMENTARY tools in that direction.

shut yarrow Sep 28, 2020, 8:08 AM

#

You mean it's for stuff like scoreboards etc?

gleaming prawn Sep 28, 2020, 8:08 AM

#

But nothing beyond the very very basics, so not really useful for that purpose (runtime networked gameplay)

spring valley Sep 28, 2020, 8:08 AM

#

they provde live environemtns right?

gleaming prawn Sep 28, 2020, 8:08 AM

#

Yes

#

they provde live environemtns right?
Ye, good for running matchmaking, etc

#

It's NOT designed/targeted to realtime gameplay

#

I'll list all providers I know of that actually give you something related to realtime networking (no judment on quality, featureset, etc). And I might forget a few, but here we go:

#

photon (several products: quantum, bolt, pun, realtime, server), mirror, mlapi, darkrift, forge, normcore, spatial-os/improbable, coherence, Steam (they have a p2p punch+relay fallback service), XBox (teredo p2p punch+relay fallback), Nintendo (also p2p punch+relay fallback), and afaik sony also offers something (forgot)

#

These are the usual SDKs/services people discuss here + dots

#

official dots + coherence are very very preview/alpha, and afaik have nothing released with their stuff

#

all the others have games released with

shut yarrow Sep 28, 2020, 8:13 AM

#

Isn't darkrift only TCP or is that something from the past?

#

I think I once ticked that one off the list because of that reason

spring valley Sep 28, 2020, 8:13 AM

#

is steam worth looking into? i think they have a lot of add on and customisation

gleaming prawn Sep 28, 2020, 8:13 AM

#

multiplay or gamlift are HOSTING services (you write the game with something like bolt, mirror, and run dedicated servers in these services)

spring valley Sep 28, 2020, 8:14 AM

#

since most indie would be releasing on steam

gleaming prawn Sep 28, 2020, 8:14 AM

#

Isn't darkrift only TCP or is that something from the past?
As I said, I did not judge anything... Just listing the SDKs which are related to realtime (that I remember of)

#

is steam worth looking into? i think they have a lot of add on and customisation
It's VERY barebones... Very, really vera

shut yarrow Sep 28, 2020, 8:14 AM

#

Wasn't asking for judgement just a yes/no 😛

gleaming prawn Sep 28, 2020, 8:14 AM

#

it just gives you a trabsport layer + invite system

#

Wasn't asking for judgement just a yes/no 😛
Yes or no depends on WHAT you want to do

shut yarrow Sep 28, 2020, 8:15 AM

#

For example a shooter or racing game, not just a point and click

spring valley Sep 28, 2020, 8:15 AM

#

any database you would suggest along with these sdk u just mentioned , it may even influnce the choice of sdk

gleaming prawn Sep 28, 2020, 8:15 AM

#

For example a shooter or racing game, not just a point and click
Then, NO

spring valley Sep 28, 2020, 8:16 AM

#

having a streamline process would be far better than hooking up a lot of stuff here and there

gleaming prawn Sep 28, 2020, 8:16 AM

#

any database you would suggest along with these sdk u just mentioned , it may even influnce the choice of sdk
It should NOT influence the choice of realtime SDK, these are completely separate problems

gleaming fossil Sep 28, 2020, 8:16 AM

#

DarkRift is using UDP and TCP for unreliable / reliable transfers

shut yarrow Sep 28, 2020, 8:16 AM

#

I'm using SQLite for database

#

Ah so no reliable UDP

gleaming prawn Sep 28, 2020, 8:17 AM

#

I'm using SQLite for database
That does not say anything... It might be just a premature choice

#

I mean, do you have a clear separation of what you need a DB for?

shut yarrow Sep 28, 2020, 8:17 AM

#

Yeah you're right maybe it is

gleaming prawn Sep 28, 2020, 8:17 AM

#

It's not even related to realtime gameplay

#

We're talking two different things...

shut yarrow Sep 28, 2020, 8:17 AM

#

Made the choice purely for sake of convenience, easy to set up and just run SQL commands I'm already familiar with

gleaming prawn Sep 28, 2020, 8:18 AM

#

DBs are used for storing:

player data (profile, achievements, owned item IDs)
match history (your runtime SDK/service might STORE data here, but they are not directly related)

spring valley Sep 28, 2020, 8:18 AM

#

do u have a sign up process if yes how do u link them w player profiles @shut yarrow

shut yarrow Sep 28, 2020, 8:18 AM

#

Yes I do

gleaming prawn Sep 28, 2020, 8:18 AM

#

Made the choice purely for sake of convenience, easy to set up and just run SQL commands I'm already familiar with
Storing gameplay/player/match data is a lot more than this...

shut yarrow Sep 28, 2020, 8:19 AM

#

Player registers and gets saved in a database, then he can login and I'll retrieve his/her information

spring valley Sep 28, 2020, 8:19 AM

#

do u have an identifier for that player like a unique id

shut yarrow Sep 28, 2020, 8:19 AM

#

Yes

gleaming prawn Sep 28, 2020, 8:19 AM

#

Just take player signup/athentication for example:

most services (like ours) let you plugin any custom authentication to allow plyers connect to the realtime network... you just provide a REST URL with some conventions

#

but again, this is just <5% of what you need for a multiplayer game

spring valley Sep 28, 2020, 8:20 AM

#

😭

gleaming prawn Sep 28, 2020, 8:21 AM

#

if you want to create an online multiplayer game, forget a bit about storage, player profiles, etc, these are "orthogonal" requirements...

shut yarrow Sep 28, 2020, 8:21 AM

#

Changing to other SQL based database isn't an issue for me though, for now this is sufficient for me

#

Exactly my point 😛

gleaming prawn Sep 28, 2020, 8:21 AM

#

The choice of database is just not related/relevant to the runtime multiplayer part... that's my only argument...:)

#

But again it depends on your ambitions

spring valley Sep 28, 2020, 8:22 AM

#

oh okay thanks for the pointers , could u suggest some source materials to get into these newokring process @gleaming prawn i am not that great w networking

gleaming prawn Sep 28, 2020, 8:23 AM

#

[about DB storage] If you plan to release a game for real, and make money out of it... you either:

use existing services like playfabs
(after a lot of experience) write your own that will be cheaper (but really really after you learn A LOT by releasing other games using services like above).
This is the road taken by developers I know

spring valley Sep 28, 2020, 8:24 AM

#

by source materials i mean somehting that can really explain the process that goes in between gameflow, signup-> gets registered-> calls to db with indentifier-> created profile something on this line

gleaming prawn Sep 28, 2020, 8:24 AM

#

could u suggest some source materials
I suggest you start with a game that is easier to network than a shooter or a racing games (these are both challenging).

spring valley Sep 28, 2020, 8:24 AM

#

i would prefer doing an asynchronous game than live game

gleaming prawn Sep 28, 2020, 8:24 AM

#

Then go to youtube and watch tutorials about Pun/Mirror, whatever you fancy

shut yarrow Sep 28, 2020, 8:24 AM

#

I think that's what Erick was talking about before, those are secundary subjects

#

Will be difficult to find an all encompassing guide

gleaming prawn Sep 28, 2020, 8:24 AM

#

i would prefer doing an asynchronous game than live game
Then you do not need per se any of the above

shut yarrow Sep 28, 2020, 8:24 AM

#

And not practical either

gleaming prawn Sep 28, 2020, 8:25 AM

#

BUT, still

#

it's all about the SIMULATION, not how you send data

#

for an async game you need:

a way to store the full game state
the game state must be compact (so it's cheap to send/receive)
the clients must be able to recreate the whole View/UI from a snapshot of the game state
simulating the turn/command on a server (or using determinism) will be important in this case)

spring valley Sep 28, 2020, 8:26 AM

#

simulating the turn/command on a server (or using determinism) will be important in this case)
@gleaming prawn

#

so this is my concern, it has t be server authoritative right?

#

maybe a dedicated server that handles these game states and assigns lobbies

shut yarrow Sep 28, 2020, 8:27 AM

#

That's a world of pain I'm not willing to undertake yet

#

I'm trying to make it semi authoritive cause I just want to make something that is fun to play, then see how popular it will be and if it;s even worth doing all that effort

#

So no server side physics, or server giving permission you can move/shoot whatever

gleaming prawn Sep 28, 2020, 8:29 AM

#

it has t be server authoritative right?
If you use determinism, NO

#

I'm trying to make it semi authoritive cause I just want to make something that is fun to play, then see how popular it will be and if it;s even worth doing all that effort
THIS

spring valley Sep 28, 2020, 8:29 AM

#

idk what determinism is and in what context

gleaming prawn Sep 28, 2020, 8:29 AM

#

I can't say better than this...

shut yarrow Sep 28, 2020, 8:30 AM

#

I know gameservers with 1000 players and they don't even have full authoritive model

gleaming prawn Sep 28, 2020, 8:30 AM

#

That's the spirit IMHO Swanson

shut yarrow Sep 28, 2020, 8:30 AM

#

It's important for them to have actual admins to keep it fun and fair

gleaming prawn Sep 28, 2020, 8:30 AM

#

I know gameservers with 1000 players and they don't even have full authoritive model
Among Us is an example...:)

shut yarrow Sep 28, 2020, 8:30 AM

gleaming prawn Sep 28, 2020, 8:30 AM

#

make a fun game...

shut yarrow Sep 28, 2020, 8:30 AM

#

Yeah indeed that is the top priority

#

It might sound weird but I'd love to see people cheat, then I know I'm on to something good

#

Nobody's going to care to cheat in a game that has 3 players

#

But yeah main point is, it is difficult to do it right (what is right anyway?) and if you can get away with cutting corners then do so

#

Anyway I need to sleep thanks for the nice talk and hope you both have a good day. Good luck with your decision @spring valley

Realtime: just the base transport layer SDK

For the app ID, it won't make a diffference, as both use the same relay servers and protocol...

If it was a Quantum App ID, then this would be important (because there's server logic going on)

Again. You are in way over your head here. Too soon to be trying game networking.

Make a few complete single player games before subjecting yourself to networking. Installing is the easy part. This only is going to get much much harder if you are new to unity.

grizzled narwhal Sep 29, 2020, 12:20 PM

jade glacier Sep 29, 2020, 4:42 PM

#

my god.

jade glacier Sep 29, 2020, 6:27 PM

#

Everything is on a numbered tick, and that is basically simulation ticks.

#

A simulation consists of Prev State + Applied Inputs = New State

#

So standard FPS handling is players collect inputs for the next tick locally, and apply them to their character for that tick, but also send them to the server. The server applies them and broadcasts it's State result for all objects.

The predicting client compares its history of results for that tick with the server's results when they arrive, and if they mismatched there is a desync.

#

When there is a desync, the client must rewind the simulation to the point of disagreement, apply the server state, and resimulate forward again, using the history of inputs.

#

The server aligns all players incoming ticks to its simulation numbering

#

Simulates them all at once, and extrapolates any that didn't arrive in time

#

Then sends out its results with the tick number

#

They may have done something like that, but that is also very old tech now

#

Not sure how that kind of system would be sane to rewind, lerp, etc

#

can you paste the line of text that seems to suggest that?

#

That is not a standard server authority practice, but time based can be done - at the cost of complexity and more CPU usage for the server.

#

I guess first question is who is this author, and what game have the produced with the system they are proposing?

#

You can do just about anything you can think of in networking. If you are willing to deal with the complexity and overhead involved in what is suggested here, it is doable.

#

It isn't typical, but it is doable.

#

Determinism goes right out the window, so you will be leaning heavily on brute force for most everything.

#

I see all of the points I am making are right there in that same doc

#

More cpu drain, more complexity, more hacks

#

Source may well have, Counterstrike and such are fully non-deterministic and have super basic simulations

#

The article seems to touch all of the pitfalls and perks... so I may have missed what your original question was.

#

Another alternative route since its a simplistic simulation is to run the simulation at an insanely high rate. You can then drop sent inputs as needed to let the server extrapolate them and such.

#

To be clear, this type of thing is very specifically tuned for fast FPS shooters. If that is what you are making, by all means give it a whirl.

jade glacier Sep 29, 2020, 7:06 PM

#

In that case though, you still wouldn't be sending "time", you would still be quantizing actions to a tick on the client... just the ticks happen so quick and often that they won't feel like they contribute to input lag.

#

Input lag with a fixed tick system would come from a low sim rate... since to keep things sane you would not apply weapon fire, jumps, etc immediately, you would apply them on the next simulation tick, so that they are in perfect agreement with any movement code.

#

You can fire shots between ticks, but to keep that sane with your sync, you have to start really getting meticulous with your lerping code and such.

#

If you have a lot of world entities and AI.. I would forget what you just read on that blog immediately 🙂

#

If your server has to run a giant simulation, you want your players to be part of that. Making them move outside of that is just more work for your physics/sim engine, and is going to create all kinds of uncertainty about where things are/were.

#

No harm in experimenting with any/all of this - but I would NOT try to implement that into a project that has to go live without a lot of proof of concept tests preceding it.

#

We might be discussing different things

#

That snippet looks like fixed tick

#

That will make for some interesting rewind and resync code

jade glacier Sep 29, 2020, 11:33 PM

#

It well may be a bit more squishy with it's ticks like that. It is a relatively old net engine, and the requirements may have allowed for that.

#

It may be that they didn't count on rock solid timing from PCs. Or they did that too allow for offtick events. I'm not sure.

#

Give it a shot. Just be aware of the complexities that come with it.

#

Rewind and resim will be significantly more complex to implement.

anyone else getting an SSL Connection Failed rn? My traffic monitor is telling me the remote certificate is invalid, not sure if its a problem on my side or theirs

urban shadow Sep 30, 2020, 9:57 AM

#

I'm having a tough time doing something I perceived as simple: syncing player metadata with Photon PUN. All I want to do is add an ID to the player, just as it has a Nickname. I tried using photonView.Owner.SetCustomProperties but either I'm doing it wrong or it's not how it should be used... Does anyone know how to do this? Or have a link that shows how to do this..? I found a serialize solution but that runs very often, and I only want to set it once. I could ofc do a check to see if the value changed and if so add it but it just feels like a lot of work for 1 id, so it's probably dumb.

gleaming prawn Sep 30, 2020, 9:59 AM

#

player properties are normally a good way to do that

#

can you post a specific technical question on why you think it's not working?

#

If you follow the manual and set custom player properties, the other game clients will receive the on properties-changed callback, etc

urban shadow Sep 30, 2020, 10:00 AM

#

After joining a channel I do: photonView.Owner.SetCustomProperties(new Hashtable {{ "videoUid", uid }});

#

Which seems to work. But then doing photonView.Owner.CustomProperties["uid"] doesn't because photonView is null.

gleaming prawn Sep 30, 2020, 10:00 AM

#

After joining a channel
You mean a room? Channels are a concept of photon chat, so I'm double checking you are not confusing things

#

in which machine?

#

you can only do that from scripts that are place in game objects that have a photonView

urban shadow Sep 30, 2020, 10:01 AM

I meant a channel, but it's specific to some other part of my app

#

lol

#

Yeah, no that part I know

gleaming prawn Sep 30, 2020, 10:01 AM

#

Well... if you have a null pointer, clearly there's some mistake in the game object setup, or something like that.

urban shadow Sep 30, 2020, 10:02 AM

It's a convenience method to help me get it, which is why I don't get it. It's on my Character which is on the prefab that has the photonview

@wheat zodiac not sure what you mean

are you saying you want host.example.com to resolve to 127.0.0.1 instead of 54.x.x.x for a process running in an ec2 instance?

#

Hello guys. I'm working on a WebGL archiviz application on Unity right now and I'm using the addressables system to help me optimize the loading size of the app, since it will have a lot of assets for the furnitures. So I'd like to ask if creating the group bundles with remote build path and remote load path will automatically separate the assets from the build and thus fasten the load time, or do I still have to manually indicate to unity that those assets shouldn't be included within the build? Thanks in advance

stiff ridge Oct 1, 2020, 9:14 AM

#

Look into addressables, I'd say. That said: Wrong channel?!

Sorry I didn't know in which channel to ask😅 This seemed the most appropriate for me haha

how do i persist network state between differnt scenes whilst using photon?

#

eg ; if i created a room in scene A but right after that my game is in scene 2 that i want the host to go to , how would that happen, as right now i get a null refernce excep pointing towards photonclient when i try to access name of room in scene 2

jade glacier Oct 1, 2020, 12:18 PM

#

Probably Custom Properties are what you are looking for? @spring valley

#

are you changing from the master server to the game server though when you change scenes? Or just changing scenes mid game?

#

Be careful to use specific networking terms... phrases like "the host to go to" can mean a lot of things.

spring valley Oct 1, 2020, 12:56 PM

#

Loadlevel(scene index)

#

It persists the network state

#

@jade glacier

jade glacier Oct 1, 2020, 12:57 PM

#

People usually use Custom Properties for that. They aren't the most efficient (they transmit and store as strings), but if it isn't a high traffic value that should do the trick.

spring valley Oct 1, 2020, 12:57 PM

#

What do you mean by high traffic value

jade glacier Oct 1, 2020, 12:57 PM

#

Gets changed often

spring valley Oct 1, 2020, 12:57 PM

#

It's usually just the network object right ?

jade glacier Oct 1, 2020, 12:58 PM

#

like if its a player position, that would be a terrible use case.

spring valley Oct 1, 2020, 12:58 PM

#

Could u gimme an example on why would we carry on same coordinates between 2 scenes?

jade glacier Oct 1, 2020, 12:59 PM

#

Not sure what that use case consists of. But I would look into Custom Properties and see if they fit what you are trying to do.

spring valley Oct 1, 2020, 12:59 PM

#

How do we achieve the custom properties?

jade glacier Oct 1, 2020, 1:12 PM

but idk

#

if i place a fake player in the scene and shoot it dies

jade glacier Oct 1, 2020, 5:04 PM

idk i just found out how to do multiplayer yesterday

do u know a fix

#

I would start by completing to Getting Started tutorial

sleek laurel Oct 1, 2020, 5:06 PM

#

i got player movement and stuff to work

#

and shooting

#

just this does not work

jade glacier Oct 1, 2020, 5:06 PM

#

I don't know what this script is trying to do that would be networked.

#

"KilledMultiplayer" doesn't really give much of a hint of what the object is

sleek laurel Oct 1, 2020, 5:07 PM

#

it should move the player to a position when hit by a bullet

#

or grenade

jade glacier Oct 1, 2020, 5:08 PM

#

You don't really even have a starting point here, I would have to walk through the entire process of working out what your projectile is, how it is identified on the network, who has authority over it, and how it interacts with objects (though that part looks like with tags)

#

Someone else will have to help you, that is WAY more topic than I can give a quick answer on

sleek laurel Oct 1, 2020, 5:09 PM

#

uh ok

elfin inlet Oct 1, 2020, 5:09 PM

#

spawnPositions.Length - 0 you sure this shouldn't be spawnPositions.Length - 1 ?

sleek laurel Oct 1, 2020, 5:09 PM

it works

¯_(ツ)_/¯

#

well

#

the spawnpos thing anyways

elfin inlet Oct 1, 2020, 5:10 PM

oh wait

yeah ure right

sleek laurel Oct 1, 2020, 5:10 PM

#

I'm looking for some help on photon webooks. I'm a complete unity noob, but I do have a working chat application that hits my BaseURL when someone signs in, although I'm completely lost on how to pass it anything other than hard coded parameters.

lucid sable Oct 1, 2020, 5:35 PM

#

anyone use mirror and know how to make a gameobject only visible to the client it was generated on?

shut yarrow Oct 1, 2020, 6:48 PM

#

I never used Mirror but I suspect you shouldn't use functions in that framework to instantiate objects, instead use the regular Instantiate function

lucid sable Oct 1, 2020, 8:21 PM

#

someone on the Mirror discord helped me sort it out. had to do with checking if (isLocalPlayer)

jade glacier Oct 1, 2020, 8:22 PM

#

That is typically the incorrect answer, it just works in simple games. hasAuthority and IsLocalPlayer get confused regularly. @lucid sable

#

Be sure to know the difference when using Unet or Mirror

lucid sable Oct 1, 2020, 8:24 PM

#

has authority has to do with whether or not whatever is doing something has authority, whereas islocalplayer is whether it is the local player

#

I only wanted it drawn for the local player, so I told it if (!isLocalPlayer) return in LateUpdate()

jade glacier Oct 1, 2020, 8:26 PM

#

If it only applies to the Local Player object then should be fine.

lucid sable Oct 1, 2020, 8:26 PM

#

yeah. it's a field of view/fog of war type deal

#

server doesn't need to know what the visible area of the player is I wouldn't think

#

at least I can't think of a situation off the top of my head

jade glacier Oct 1, 2020, 8:27 PM

#

I'm not fully following your questions, but sounds like you have it sorted.

lucid sable Oct 1, 2020, 8:27 PM

#

https://ncase.me/sight-and-light/ scroll down a bit and mouse over

#

like that

#

but yeah I've got it sorted

shut yarrow Oct 1, 2020, 10:49 PM

#

Can I just share I've rewritten my server with C++ and now memory use is stable and about 9 times less as with C#? 😛

#

I love C# but managing memory is such a pain in the back, for some reason I can't keep a stable memory use and it just keeps growing overtime, regardless of manually calling garbage collector

#

For example in C# the server used about 10 MB after starting, and after 2 days sitting idle it was 40 MB. With C++ after 2 days it's still around 1MB

#

Still need to figure out for my clients if they have this issue when being connected for longer periods, I suspect it's less of an issue because they deal with a lot less data than the server but having that sorted would be nice

jade glacier Oct 1, 2020, 11:19 PM

#

You can make a memory allocator of your own in C# without having to go through that mess.

shut yarrow Oct 2, 2020, 12:02 AM

#

Please enlighten me. I've done something fairly simple with a wrapper around the MemoryStream class which returns stream.ToArray() each time and I feel like that could be a problem because it just creates new arrays all the time that the garbage collector (in theory) has to pick up on

jade glacier Oct 2, 2020, 12:03 AM

#

yeah, that is what ToArray does

shut yarrow Oct 2, 2020, 12:04 AM

#

Ideally I'd have a single buffer and write my stuff to it and just reuse it but I find that a terrible workflow in C#

jade glacier Oct 2, 2020, 12:04 AM

#

Which networking library?

shut yarrow Oct 2, 2020, 12:04 AM

#

ENet

#

It has a C# wrapper which I use for the client and I use the native library for the server

jade glacier Oct 2, 2020, 12:04 AM

#

No clue on that front, because you need to send it an arraysegment<byte> or a byte[] and a length

#

Depends on what the library can take, hopefully they have a buffer and length type available to you.

shut yarrow Oct 2, 2020, 12:05 AM

#

I think the library itself isn't causing the problem, it's me messing it up

jade glacier Oct 2, 2020, 12:05 AM

#

You have to look into the enet API for ways to pass data

shut yarrow Oct 2, 2020, 12:06 AM

#

It returns you a byte array from the native library, I copy that to another buffer, then call a method which disposes of the data in the native library

jade glacier Oct 2, 2020, 12:06 AM

#

No, you need a way to get a byte[] to it that is the wrong size, and a way to tell it how much of that to use.

#

If it only accepts a perfectly sized byte[], you will have to allocate.

#

But I suspect that is accepts different types of objects and wrappers.

shut yarrow Oct 2, 2020, 12:06 AM

#

Well it tells me how many bytes are in the buffer though

jade glacier Oct 2, 2020, 12:07 AM

#

Does it let you tell it what byte to start reading from and how many bytes to read?

#

Send(byte[] buffer, int offset, int bytes)

#

something along those lines

shut yarrow Oct 2, 2020, 12:07 AM

#

I suspect it just uses a single internal buffer and it fills it, then returns you a pointer to it with the length of the data

#

But the wrapper takes care of the intrinsics, I'm just consuming some simple interface calls

jade glacier Oct 2, 2020, 12:08 AM

#

I have nothing to tell you, other than you have to look at the enet API and see if there is a way to send a buffer with size info.

shut yarrow Oct 2, 2020, 12:08 AM

#

It gives me info on size

jade glacier Oct 2, 2020, 12:08 AM

#

Hopefully it has an overload or a method that accepts a buffer and some size info

#

you are misunderstanding I think then

#

you don't want a buffer size from it... you want to GIVE it a buffer size.

#

On the read side, it gets more complicated

#

unless it gives you a nonalloc method, its likely going to allocate a byte[] that is the exact size as the data that was in the packet.

shut yarrow Oct 2, 2020, 12:10 AM

#

I think I can actually set the internal buffer size but I think that's not the issue

jade glacier Oct 2, 2020, 12:10 AM

#

Either way, you have to see what the API gives you for send and rcv... if it lacks nonalloc options, you will have to modify enet to have them.

shut yarrow Oct 2, 2020, 12:10 AM

#

I think all the serialization/deserialization what I'm doing is doing a number on the garbage

jade glacier Oct 2, 2020, 12:10 AM

#

I have no idea.. without the API in front of me. All I can say is check the API for nonalloc options.

shut yarrow Oct 2, 2020, 12:10 AM

#

It does have a way to assign a custom allocator, haven't looked into that though

jade glacier Oct 2, 2020, 12:11 AM

#

If you can give it a non-alloc, you would want to send your backing byte[] from your MemoryStream

#

and a bytecount

shut yarrow Oct 2, 2020, 12:11 AM

#

But it seems to dispose fine of the data it receives, the problem is on how I do things with my data after it is received

jade glacier Oct 2, 2020, 12:11 AM

#

Not sure if MemoryStream will give you a ref to its backing data though

shut yarrow Oct 2, 2020, 12:11 AM

#

Not sure either, I only know of the ToArray() function

jade glacier Oct 2, 2020, 12:12 AM

#

GetBuffer()

#

it does

#

That will have all of the empty padding though

shut yarrow Oct 2, 2020, 12:12 AM

#

Thanks I need to look into that then, hopefully that saves me from having to allocate new arrays each time and just use whatever already exists

jade glacier Oct 2, 2020, 12:12 AM

#

So if you just send that, you will be sending a bunch of garbage.

shut yarrow Oct 2, 2020, 12:12 AM

#

Ah that's not good

#

I feel like constantly fighting with C# to get it to behave nicely and not waste my memory -_-

jade glacier Oct 2, 2020, 12:13 AM

#

Yup, that is the tradeoff with managed languages

shut yarrow Oct 2, 2020, 12:14 AM

#

I can get away with doing server in C++ but for the client it's not an option

#

I will look into the custom allocator options and that GetBuffer function

azure nimbus Oct 2, 2020, 12:15 AM

#

well. it is actually... the guys from uMMORPG have a transporter that add a guy in the middle, probably in c++ which actually does the server communication

#

so the c# client communicate with the c++ client, and the c++ communicates with the server

jade glacier Oct 2, 2020, 12:16 AM

#

I doubt Vis2k is doing anything like that in C++

shut yarrow Oct 2, 2020, 12:16 AM

#

So you mean the client does interop with a C++ plugin?

#

I totally want to prevent having to write all that myself 😄

jade glacier Oct 2, 2020, 12:17 AM

#

What kind of game are you doing that is driving this much complexity?

shut yarrow Oct 2, 2020, 12:17 AM

#

I'm using this wrapper because the guy who made it put a lot of time in it already and he knows better than me how to do these type of things

jade glacier Oct 2, 2020, 12:17 AM

#

That sounds like a death spiral to me

#

Who's enet library?

shut yarrow Oct 2, 2020, 12:18 AM

#

I'm pretty happy with it actually, it is not the cause of my memory problems

#

There's more sources to get it from, but I got mine from NXRightHere on github

azure nimbus Oct 2, 2020, 12:18 AM

#

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

jade glacier Oct 2, 2020, 12:18 AM

#

if its NX's, it for sure has proper methods

shut yarrow Oct 2, 2020, 12:18 AM

#

He made changes to the original C library so it's easier to wrap in a C# assembly

jade glacier Oct 2, 2020, 12:18 AM

#

just use the GetBuffer, and pass it that and the used byte count

azure nimbus Oct 2, 2020, 12:18 AM

#

sorry, maybe i misunderstood what booster was about

jade glacier Oct 2, 2020, 12:19 AM

#

Not sure what he offers on the read side, I haven't looked at his enet implementation, or if it has a nonalloc method to use.

#

Are you on his discord server? @shut yarrow

shut yarrow Oct 2, 2020, 12:19 AM

#

No I didn't even know he had one

#

But again, I'm quite sure my problems have to do with my lack of understanding how to manage memory in C#, it's not the wrapper that I'm using

#

I find that heaps easier with C++ because it's kind of how the entire language was intended to used, to do it yourself and then get a crash on the simplest of things if you mess up 😛

#

And surprisingly enough no crashes yet, no memory leaks yet

jade glacier Oct 2, 2020, 12:21 AM

#

mixing your C++ and C# like that wouldn't be the path I would take.

shut yarrow Oct 2, 2020, 12:21 AM

#

Just no idea what to do for the client, other than take your advice and look into th GetBuffer method

jade glacier Oct 2, 2020, 12:22 AM

#

The reason he made a C# version is so that you could keep everything right inside of Unity without passing between libraries like that.

shut yarrow Oct 2, 2020, 12:22 AM

#

It's not really mixed though, it's only on the server

jade glacier Oct 2, 2020, 12:22 AM

#

If you can manage the complexity, go for it.

shut yarrow Oct 2, 2020, 12:22 AM

#

Server uses the same library, but not the wrapper, just the native

jade glacier Oct 2, 2020, 12:22 AM

#

The server has NO game logic?

#

Is it just a relay or something?

shut yarrow Oct 2, 2020, 12:23 AM

#

Very little right now

#

No not just a relay but does very little as of yet than passing through messages

#

Just focusing now on making it as stable as I possibly can and also very simple to extend my future plans

#

Server receives packets, reads them, then calls a callback in a GameMode class which I use to do all game logic

#

I don't find this too complex, it's actually fairly simple

#

I'd dare say simpler than in C# 😄

#

Some things are little bit different, but the big advantage is I'm not fighting to keep memory use low and stable

#

Other than that it's exactly the same structure as the server I did in C#

#

Using the same library, but instead of the wrapper that interops with the native libary, I use the native library directly

#

If you look at the github you'll see how little documentation ENet has, because there's isn't much to it from a consumer's point of view

#

The wrapper uses a little less code to set up a server or a client because a lot is abstracted away, but using it is not that much different in practice

It likely matches the C+ api

Is unity network free?

gleaming prawn Oct 2, 2020, 8:20 AM

#

what do you mean by Unity Networking? Unity has NO working library to offer for multiplayer... You need to use tools like Photon, Mirror, etc

#

And what do you mean by free?
That downloading and using the lib is free of charge, sure a few are... But that you will pay nothing to have a multiplayer game running, no so... You need to pay for servers (or at least relaying servers), unless you are doing just a LAN game.

kindred wave Oct 2, 2020, 8:52 AM

PUN is free until a certain amount of users

gleaming prawn Oct 2, 2020, 8:52 AM

Yes, but that's only enough for development or if you are doing something like a school project

#

Same goes for normcore, and other production-ready services

That's not really how you set room properties. And you can't see them before joining the room, or get them after leaving the room like that.

#

Where are you getting that code sample from that is showing you to do it this way?

#

Whatever tutorial that is from, needs burning. :)

#

it looks like you are trying to set the rooms properties from outside of a room?

#

ah, it was set inside the room

#

I think you have to enable something to make properties visible outside

Tobi makes reference to it in this forum topic

Get Custom room properties in Lobby (PUN2)

I want to get the properties of a room when I'm in lobby. I'm sure that the properties are setted to show on lobby with adding a string to it. But, at...

that is really old though, so likely is talking about pun1

so probably is relevant.

and i dont get why

any help?

You should debug that foreach loop to see if it actually runs

Also this is a clusterfuck with 3 scripts having to do something with a room, it'll be more to the point to make it a single script

@jade glacier I know how to do client input resimulation with fixed step movement (e.g using transform.Tranlate to apply movement). But this movement has many problems. I tested a non-resimulation velocity movement and thats much better but I can't seem to think of a way to do velocity movement resimulation?

grizzled narwhal Oct 3, 2020, 10:39 AM

@feral valley multiplayer games are totally different from ssingle player you will have to rewrite most of it

Even stuff like gravity modifiers on objects

and movement from axis

and OnMouseDown()...?

Could you point me in the right direction as a total beginner?

#

I was looking at firebase, forge, photon...

jade glacier Oct 3, 2020, 11:36 AM

#

@grizzled narwhal not really following the question sorry

grizzled narwhal Oct 3, 2020, 11:37 AM

#

There are 2 types of movement: Fixed step e.g adding a vector to position every movement step. And velocity -> adding force to the rigidbody and moving that way. I know howw to make resimulation with fixed step (thats easy) but I don't know how to do it with velocity?

jade glacier Oct 3, 2020, 11:45 AM

#

Physx isn't deterministic in a way friendly to that. But if you go that route you need a history of velocity states as part of your history and state from the server.

grizzled narwhal Oct 3, 2020, 11:45 AM

#

yeah mhh

weak plinth Oct 3, 2020, 12:13 PM

resim with velocity, like rewinding and stepping the physics simulation forward? could never get it working good in physx. there are lots of guides and examples out there though

jade glacier Oct 3, 2020, 12:19 PM

#

It will never be 100% back in agreement,. Since you can't store the physx state.

I'm investigating network layer options for my current project. Has anyone used MLAPI? Can you tell me if it supports clients connecting to multiple servers? Based on this documentation, I would assume not:
https://mlapi.network/wiki/networking-manager/

MLAPI

NetworkingManager

The NetworkingManager is a script component handling all your Networking related settings, your Networked Prefabs and your registered scene names. A Transport component is needed on the same GameObject. It is responsible for handling IP adresses and additional settings.

jade glacier Oct 3, 2020, 3:00 PM

#

Typically people needing that kind of extreme use case will be very advanced and experienced network devs, and they typically will be rolling their own networking library for that. MLAPI is very similar to Unet HLAPI and Mirror. It is meant as a messaging layer and net entity management system for general use.

Trying to get some of these HLAPI libraries to do anything exotic often results in doing more work to make them conform than it would to just make your own.

jade glacier Oct 3, 2020, 5:43 PM

#

This is why simulation is king, and you don't blur messaging with your state syncs

#

messaging <-> Tick Based State/Input Buffers <-> Simulation

#

applying messages directly to states will create all kinds of interesting race conditions and anti-deterministic outcomes.

jade glacier Oct 3, 2020, 6:16 PM

#

Once all on a tick, apply events at the end of interpolation, rather than the start.

brittle river Oct 3, 2020, 7:12 PM

#

@jade glacier Appreciate the response. Trying to avoid high-level and low-level. I just want something in-between to give me performance & not have to deal with some of the lower-level headaches of packet stacking & splitting, while also having UDP support with reliable & sequenced messages. I've been toying with the idea of using LiteNetLib, but want to know if you had any specific recommendations?

#

I want to completely avoid anything that uses reflection for their RPC handling 😆

#

I might just have to roll my own.

jade glacier Oct 3, 2020, 7:29 PM

#

That is why tick based is better than time based.

grizzled narwhal Oct 3, 2020, 7:31 PM

Is there a way, to have LAN in a Unity game, without renting any extra servers or anything?

shut yarrow Oct 4, 2020, 12:29 AM

do you know a good tutorial @shut yarrow

shut yarrow Oct 4, 2020, 12:38 AM

#

It's quite a general question to be honest. If we're not just talking about the actual coding aspect of it, you should have a machine which can function as a local server the others in the same network can connect to. This can be as simple as doing port forwarding in the router and the clients connecting to that machine

woah

ok

shut yarrow Oct 4, 2020, 12:39 AM

If you want to know more about the actual coding part, there is a lot of information to take in, and I suggest you either look into existing frameworks to do this, or search for TCP/UDP server and it'll lead you in the right direction

GGPO is just a very small

wrapper

#

around predict/rollback logic

for you to hook into

if the game wasnt made to be deterministic and predict/rollback

it's.. well, a lot of work

I know that will be a lot of refactoring

@sterile void you might need to clarify that question.
@jade glacier
Ok so I have a player with a camera attached as a child.
The problem is: I want to make a FPS multiplayer game, but I use physical bullets, so I want to spawn those bullets. The problem is I use the bullet script on my camera and for spawning I need to use [command] function and so to add a network identity to the camera, but te player already has a network identity so there is a bug...

graceful zephyr Oct 4, 2020, 11:35 AM

#

if the game was just built in unity, like normal unity SP game?

#

it's a complete re-write

#

for make it fully deterministc predict/rollback

#

usually

#

havent seen the game ofc, but that's just speaking from experience

azure nimbus Oct 4, 2020, 11:37 AM

#

I normally use an ECS approach. which make everything easier. however, I do believe that he code everything in plain unity

sterile void Oct 4, 2020, 11:38 AM

#

@jade glacier nevermind, i will replace the script in the player and use the position and rotation of the camera for spawning

graceful zephyr Oct 4, 2020, 11:38 AM

#

@azure nimbus yeah... idk what to say 😄

#

so do u have a question?

#

around GGPO

azure nimbus Oct 4, 2020, 11:38 AM

#

it is indeed windows only?

graceful zephyr Oct 4, 2020, 11:39 AM

#

its native C/C++ i think?

#

u should be able to port it

#

just yeah u might need to modify it

#

ofc

lusty crow Oct 4, 2020, 11:39 AM

#

there are some docs in the official github repo, afaik ggpo is only for windows,

but james is working on backroll which is basically a rollback implementation for c#/unity

#

not sure how far he is with that though

azure nimbus Oct 4, 2020, 11:40 AM

#

GGPO has so hard dependence with vcruntime...

jade glacier Oct 4, 2020, 11:40 AM

#

Yeah, don't try nesting network identities. Command in Mirror sucks, so you will have to get messy with your setup @sterile void

graceful zephyr Oct 4, 2020, 11:40 AM

#

@azure nimbus it can probably be separated

lusty crow Oct 4, 2020, 11:40 AM

#

also, to make your game compatible to ggpo, the simulation should be deterministic, be able to simulate multiple logical frames in a single visual frame,
be able to save complete game state and restore game state from a save state,
and.. I think those are the main requirements

#

there are certain methods for ggpo you need to hook up to and those are some of the things you have to fulfil for it

#

I haven't really been here recently, have you seen james recently fholm?
I'm sure he knows things about ggpo

graceful zephyr Oct 4, 2020, 11:43 AM

#

no i haven't actually

#

but i've been away for a month or so also

lusty crow Oct 4, 2020, 11:43 AM

#

ah I see

graceful zephyr Oct 4, 2020, 11:43 AM

#

from this corner of the internet 😄

#

but even then the hard part isnt GGPO, the hard part ismaking a game that can do what GGPO needs u to do

lusty crow Oct 4, 2020, 11:44 AM

#

have been leaving ecs kinda, but actually before I finished to implement what I wanted 😅
as I understood it, ggpo is handling transport of packages, connections, detecting when states are out of sync and some primitive input prediction I think - not sure about the later.
but all else to set up for it has done in the game code custom to your game

graceful zephyr Oct 4, 2020, 11:45 AM

#

ggpo just has the basic plumbing for predict-rollback, input prediction, etc.

#

that's about it

#

and it has stubs for socket plumbing afaik

azure nimbus Oct 4, 2020, 11:45 AM

#

@graceful zephyr , so, your suggestion is to open the GGPO source up and remove the vcruntime dependence?

@lusty crow, I did read about it. like was telling fholm, I use a ECS approach there how the data is apart from render. so I can execute the systems many times and then run the render. so at first sight it could fit GGPO requeriments...

lusty crow Oct 4, 2020, 11:45 AM

#

when I first had the idea to implement rollback netcode, it was basically a completely rewrite of my game ^^

graceful zephyr Oct 4, 2020, 11:46 AM

#

@azure nimbus i mean if you want to implement GGPO... the first place to look would be GGPO source code and see what needs to be done to make it work for you

#

that seems like a logical first step 😄

azure nimbus Oct 4, 2020, 11:47 AM

#

I just unsure if GGPO is the right rollback for my friend, since it has some dependence with windows only stuff

graceful zephyr Oct 4, 2020, 11:47 AM

#

there's not many other options

azure nimbus Oct 4, 2020, 11:48 AM

#

would you guys suggest some other rollback lib to make things easier?

graceful zephyr Oct 4, 2020, 11:48 AM

you can make it from scratch ofc

there is none afaik

apparently it is conveniently possible to just make a snapshot from all relevant entities in an ecs world?

what you want to do sounds exactly like what james was working on for his rewrite of the smash-like game fantasy crescendo where he was testing out his library https://github.com/HouraiTeahouse/Backroll

not sure if he is still on this server though, I checked the names, but there is nobody that stands out to me as him

azure nimbus Oct 4, 2020, 11:48 AM

#

I hear about crescendo before...

#

Maybe I can contact him...

graceful zephyr Oct 4, 2020, 11:49 AM

#

FWIW i am the lead/inventor of photon quantum, its the only commerically available predict-rollback i know of

#

but its not free/open source ofc

lusty crow Oct 4, 2020, 11:50 AM

#

oh nevermind, he is still a member of this server, james7132
not sure why I didn't find him before

#

but his last message was on the ... 8th of september?

#

here

azure nimbus Oct 4, 2020, 11:51 AM

#

yeah, by a quick peek in the backroll repo, definitely he is ahead of me and already faced that I'm facing right now!

#

@graceful zephyr I image that you are photon related due your role and suggestion.
Well, I'm open to use a commercial asset. I will check about photon quantum.

my friend have a hard deadline for the February. If he will need to rewrite everything, the soon the better

#

@lusty crow, I may leave him a message.

graceful zephyr Oct 4, 2020, 11:56 AM

#

correct

#

like i said lead dev on photon quantum

azure nimbus Oct 4, 2020, 11:57 AM

#

the plain unity approach is such a pain for online games

#

@lusty crow, why you are leaving ECS?

lusty crow Oct 4, 2020, 11:58 AM

#

I'd be interested too how his rollback ecs adventures went and what he's working on now.

it depends, but.. what's certainly true is that for a network game compatible architecture, it is much better to think at it from the very first minute of development and align architecture decisions towards it, but that also requires prior knowledge of it.

I think it is often unavoidable to have rewrites or iterations while being in the process or learning how something works

#

I mainly wanted to revisit something I have done in 2018,, a bullet hell game, and thought ecs was perfect for that use case.
With implementing ecs physics to a bullet hell game but.. I kinda lost motivation.

all I had left was to to make job compatible animation curves which I already had in the old bullethell game, (but it works differently know, as you can use blob assets for things like these now), and make some levels.

Hello there,
I have a quick question.

I am planning on making a fps game with 32 - 64ish player multiplayer support.

I want to get started learning networking and would like to know where to get started.
What would be the best recommended netcode solution for my application ?

jade glacier Oct 4, 2020, 12:16 PM

#

If you haven't completed several smaller networked games, I would consider doing that first. 32 to 64 players creates all kinds of difficulties you don't want while learning networking.

obsidian summit Oct 4, 2020, 3:01 PM

#

I've got a small problem (using photon 2 btw). I got 2 players, both can enter a room and start up a game. When they are in the game, and one of them disconnects, it's not their own character that gets destroyed, but the other player's. So player 1 leaves, and player 2's character gets destroyed, so then player 2 gets ownership of player 1's character. I really don't know why this happens

#

~~also, every client only has ownership of their own character~~

#

nevermind, fixed

Hello, could someone tell me how I can start making a server for unity?

Mirror is usually people's first step in that direction @grand elm

I'm really very new and I don't know what that mirror is

In our course they tell us that we have to learn on our own

jade glacier Oct 4, 2020, 4:25 PM

Look for Mirror on the asset store, they include links to their discord and such there.

Where should I start looking for hot to make a UDP server that doesn't block on receiving packets?

jade glacier Oct 4, 2020, 5:48 PM

#

That will just be based on your transport choice and settings.

hollow pike Oct 4, 2020, 5:58 PM

I meant client, but it seems to be easy to use for that purpose as well?

jade glacier Oct 4, 2020, 6:01 PM

You won't get anywhere near 255 players connected to a room though, even with a simple game that would add up to a brutal amount of data per second.

Hi dudes, i'm want to create a similar game like heartstone, what is the best choise for online part? i mean, what is the best framework for create games to fight 1vs1 with players?

lusty crow Oct 6, 2020, 10:15 AM

#

if you want to have it competitive, you probably want to have an authoritative server that keeps tracks of games/game states to prevent cheating or at least to make it harder,

requirements seem to be 1vs1, and latency is usually not a big issue with card games, so it is okay when messages are a bit delays - meaning you don't usually need prediction logic, you just apply the effects or data the server sents to you when you get it.

I'm not sure about the best choice, but Mirror would certainly be capable of that.

you should also ask yourself if it should be possible to completely run the simulation on the server side, using only inputs from the clients, and if so, how to do it.

Hey I'm new to networking in Unity.

I've setup a NodeJS back-end which has endpoints
/auth/me <= returns te player

Now I am at a points where I do so many requests at different layers and points (hopefully not more than 10 requests, but I need to take action ASAP!)
What is the best way to manage routes and requests? I use IEnumerator in my requests, dunno if that is how it should be?

#

is there any tutorial or anything I can read? Because I can't find anything useful

silver steeple Oct 6, 2020, 5:49 PM

this is how I personally do it. Create a class to wrap the request.

Anyone using steamworks for matchmaking? I have it working if I apply no room filters but if I apply AddRequestLobbyListNearValueFilter I get zero results.

Wondering if anyone has any examples of use for it I think I’m doing it right. I apply lobby data on the host. Then in client I’m applying the request before attempting to search. Only thing that stands out to me is when you assign lobby data the data is required to be a string by steamworks.net but the filter uses an int (I am assuming it is converted by steam?)

#

SetLobbyData
bool SetLobbyData( CSteamID steamIDLobby, const char *pchKey, const char *pchValue ); (C++ version from steam) also shows it using a string

jade glacier Oct 7, 2020, 6:44 PM

Quantum is aimed at funded studios, so it costs a bit to get into and isn't really for hobbyists at the moment. But for funded projects should be the first platform investigated. It isn't a fit for everything, but if it is a fit, it is the hands down winner in most areas.

Past that, largely you should try tutorials for Pun2, Mirror/MLAPI, and Bolt to get a sense of what the architecture and hosting implications are for each.

Hi! So I’m currently trying to make a physical bullet with Unet but my problem is that the bullet move too fast and go mostly trough the enemy player...
Setting the rigidbody to continuous works, but not with networked player, so is there a good way to make the player detect when he is hitted everytime, and to stop the bullet going through the player?

high night Oct 8, 2020, 10:09 PM

#

@sterile void How do you actually handle the bullet?

slim ridge Oct 9, 2020, 12:00 AM

#

with Unet problem 1
your client needs to predict the hit using continuous collision detection or the server needs to tell the players when they got hit

#

or whichever client has "authority" tells the other client they got hit

Hey all, with Unity Web Request, if i had something like ```cs

using (UnityWebRequest www = UnityWebRequest.Get(url) {
yield return www.SendWebRequest();
}
}

#

Are you able to resend that request?

#

(within the same scope i mean sorry)

#

so,

IEnumerator Request () {
  using (UnityWebRequest www = UnityWebRequest.Get(url) {
    yield return www.SendWebRequest();
    yield return www.SendWebRequest();
  }
}```

@sterile void How do you actually handle the bullet?
@B.A.R.G.O.S#0973 So I’m currently spawning my bullet (with has identity and transform sync) the bullet move were I’m currently aiming, but because I want to simulate bullet drop, I can’t use raycast for applying damage...
So I decided to use collision between the bullet and the enemy player(the player has identity and transform sync) my problem is 90% of the time, the bullet go trough the enemy player even if the bullet has rigidbody set to continuous.
So what can I do if I want to apply damage with physical bullet? Or how can I make the bullet detect correctly the enemy player?

sterile void Oct 9, 2020, 5:33 AM

#

@high night So I handle the bullet by using raycast and raycasthit. In my LateUpdate method, raycast verify I’m hitting something, if yes, I set the target to the hit point, else I detect the ray.point(1000) and set the target at this point.All the information about the target are in a vector variable.
Then, I use command to Instantiate then spawn the bullet. Then I make the bullet go towards the target (with physics).
My bullet has a sphere collider, a rigidbody set to continuous, a network identity and a network Transform set to sync rigidbody3d.

high night Oct 9, 2020, 5:55 AM

#

@sterile void You should just sync the health and bullet hit visual effects from server

#

dont let client modify health and visual effects

sterile void Oct 9, 2020, 6:00 AM

#

@sterile void You should just sync the health and bullet hit visual effects from server
@B.A.R.G.O.S#0973 I know, I’m doing that, nothing changes...

inland lion Oct 9, 2020, 10:58 AM

#

What is your guys' opinion on spatialOS

high night Oct 9, 2020, 11:57 AM

#

@sterile void You wont expect or accept OnCollisionEnter or aything to trigger in client
Client wont care about collisions and physics, disable physcis if you want or set kinematic

#

Client will only spawn hit effect when server tells it to

jade glacier Oct 9, 2020, 12:22 PM

#

Typically for state transfer, as BARGOS is saying - you will set all objects that are not the authority version to be kinematic. Trying to replicate physics will devolve into an unmanageable mess.

You only simulate physics on the authority server or client - then you broadcast the transform state to others.

jade glacier Oct 9, 2020, 12:44 PM

#

The exception being any place you do client prediction. For example each player likely will simulate their player locally immediately, and the server will apply the same inputs and simulate it as well, and the server sends out the resulting state. But for most objects all clients are just lerping between previous state snapshots - rather than trying to replicate physics.

I wouldn't rely on "official" as being a good thing when it comes to networking. Unity has a horrific track record with its networking solutions.

azure mango Oct 9, 2020, 2:39 PM

#

So it would be better using something like Mirror, Photon etc?

jade glacier Oct 9, 2020, 2:40 PM

#

I don't recommend anything, since I work on one of said libraries. I do recommend scrolling up and reviewing the chat history on the topic though. It comes up often.

azure mango Oct 9, 2020, 2:41 PM

#

Okey, thanks anyways

orchid ore Oct 9, 2020, 4:15 PM

#

Can someone suggest a good mirror tutorial?

#

One which explains how to synce movement , shooting , etc properly among all clients?

jade glacier Oct 9, 2020, 4:43 PM

#

I would start in the Mirror discord channel

#

Far more Mirror specific discussion there

left knoll Oct 9, 2020, 5:14 PM

#

So I am confused, what's the correct way to do networking in Unity in 2020? Do I need a Unity Package? Should I just use .NET?
I want to try out a simple exercise for now, simply join in a Scene along with another player and move around together

jade glacier Oct 9, 2020, 5:47 PM

#

Scroll up @left knoll that question comes up every few hours.

left knoll Oct 9, 2020, 5:48 PM

#

So HLAPI is the new way

#

unet is the deprecated one

#

and I don't really wanna touch DOTS lol

prime beacon Oct 9, 2020, 5:54 PM

#

Photon/mlapi/mirror

#

Depends on what you want

left knoll Oct 9, 2020, 5:55 PM

#

Just to start networking with a simple example

#

All the examples I've found so far is "make X-complicated game using some specific third party library"

#

I don't want a MMO, I guess maybe the best I could describe it is "Among Us/FallGuys" networking capabilities

#

join a room with 5-10 players, have them broadcast around their coordinates and actions with a server, that's it

prime beacon Oct 9, 2020, 6:00 PM

#

Check out photon pun

#

Should be easiest one

shut yarrow Oct 9, 2020, 6:00 PM

#

You haven't really look well then because you would've found photon pun as most likely answer

left knoll Oct 9, 2020, 6:01 PM

#

There's a million answers and videos from all the years out there. Like the Brackeys one is using the UNet

#

I was so confused because I thought Unity would have a built-in system, but most people I've asked told me to not use the Unity networking as it's not ready or something

prime beacon Oct 9, 2020, 6:02 PM

#

Its deprecated

#

Photon pun come with an example scene

#

You can move around and fire

shut yarrow Oct 9, 2020, 6:03 PM

#

Yeah it sucks but pun has been filling that gap for many years, it's probably most easy solution for beginners who just want to try things out with not too many features

left knoll Oct 9, 2020, 6:04 PM

#

And like, say I use Photon, how crossplatform would that be? Would at least do Windows and Android? I am assuming consoles are an entire new beast with networking

inland stag Oct 9, 2020, 6:05 PM

#

Unity does not have a working networking solution right now.
For researching, I suggest looking at all of the available solutions and seeing what each of them offer.
Photon PUN is a good choice though.

shut yarrow Oct 9, 2020, 6:05 PM

#

Not sure but I think they also have android support but you might have to pay for that

prime beacon Oct 9, 2020, 6:05 PM

#

Pun support all platforms afaik

shut yarrow Oct 9, 2020, 6:06 PM

#

But since pun is basically free while you're developing there's not much to lose

left knoll Oct 9, 2020, 6:06 PM

#

I'll try it out, this is the correct one, right? https://assetstore.unity.com/packages/tools/network/pun-2-free-119922

shut yarrow Oct 9, 2020, 6:06 PM

Yes

inland stag Oct 9, 2020, 6:07 PM

#

Also, if you read the description of the asset, it mentions cross-platform support.

#

Same with their official website.

left knoll Oct 9, 2020, 6:08 PM

#

Ahhh nice

#

I am also looking at the 2021 Unity roadmap and seems a new stable Networking is planned for then

shut yarrow Oct 9, 2020, 6:08 PM

#

Don't hold your breath on it

left knoll Oct 9, 2020, 6:09 PM

#

Yeah, roadmaps can change

inland stag Oct 9, 2020, 6:09 PM

#

⬆️ Also, networking requirements are specific to each game and there will never be one library that works for everything.

left knoll Oct 9, 2020, 6:09 PM

#

Oh yeah, and not to mention platforms

prime beacon Oct 9, 2020, 6:09 PM

#

Its 2020 and Unity still dont have decent networking

#

I hope next one will be good

shut yarrow Oct 9, 2020, 6:10 PM

#

Yeah and like mentioned before, Unity has a terrible track record of networking features and they start something new just to drop it like a rock and then promise to do better somewhere in the future

#

Wouldn't be the first time for Unity to half ass a feature

prime beacon Oct 9, 2020, 6:11 PM

#

Yes lol

left knoll Oct 9, 2020, 6:12 PM

#

Well one huge issue I had with Unity was Input and they did a pretty decent job with the Input System

shut yarrow Oct 9, 2020, 6:13 PM

#

In their defense that's quite a fundamental piece of a game engine but networking always has been weak from their side and it looks more like a marketing move to get more people to jump on board when they offer it

left knoll Oct 9, 2020, 6:14 PM

#

As evidenced by the success of games like Mediatonic’s Fall Guys: Ultimate Knockout, great multiplayer games are possible in Unity today, and we will keep making it easier.
Hehe

#

Oh uh, Photon requires an account.. for what?

shut yarrow Oct 9, 2020, 6:26 PM

#

To obtain an Application ID

prime beacon Oct 9, 2020, 6:26 PM

#

Its a paid service

#

20 CCU is free tho

left knoll Oct 9, 2020, 6:26 PM

#

Oh.

#

Are there any other libraries that don't require Signup? Maybe Mirror?

jade glacier Oct 9, 2020, 6:35 PM

#

Mirror and mlapi work like Unet HLAPI. No account needed since there is no relay or matchmaking. You will eventually have to sort out how to host though.

left knoll Oct 9, 2020, 6:35 PM

im trying to add multiplayer to my connect 4 game using PUN2, and i have rooms of maximum 2 players, whenever a player joins a room, he has the option to ready up, but the ready up method is on an instantiated prefab, and it gives me this error:

i also have visuals for when a player readies up

the outer circle should light up when pressing Ready Up but it doesnt because of the error

so in my game when i kill the other player, they get teleported (they die) to me (temporarily) but nothing happens for the other player

any help?

i am using a raycast shooting system and health

weak plinth Oct 10, 2020, 4:19 PM

Guys,does MLAPI have player restrictions?

jade glacier Oct 10, 2020, 4:21 PM

#

Probably not in the sense of how many connections can be made with the various transports. But you likely will hit some CPU and bandwidth issues sooner than you are hoping.

weak plinth Oct 10, 2020, 4:22 PM

About the CPU,how can this be improved?

jade glacier Oct 10, 2020, 4:57 PM

#

@weak plinth No answer for that. You have to see where the bottleneck forms.

#

but once you get past 16 connections to a server you have to start being more and more careful. Doubling the player count exponentially increases the workload for most systems.

woeful badge Oct 10, 2020, 5:27 PM

Networking newbie here.
What tools would you guys recommend I use for a small multiplayer games?
I'm looking to include basic Leaderboard and Text Chat System.

I've had a look at Mirror on in the Asset Store, and I've heard about Vivox, which allows up to 5000 players.

weak plinth Oct 10, 2020, 5:37 PM

#

but once you get past 16 connections to a server you have to start being more and more careful. Doubling the player count exponentially increases the workload for most systems.
It is written that MLAPI can safely hold 64 players

shut yarrow Oct 10, 2020, 5:54 PM

#

@woeful badge what do you consider a small multiplayer game? Never heard of Vivox, but it's not very likely you're going to have 5000 players on a single server anyway so that is kind of meaningless tbh

#

To me sounds like your best bet is to start with photon unity networking (look it up in the asset store)

woeful badge Oct 10, 2020, 5:59 PM

#

@shut yarrow Thank you for the response.
Sorry, I meant that Vivox allows up to 5000 players for free on the server at a time, over multiple active games.

I only want something like 10 players per "room" really.
I will have a look at Photon, if it's free.

Only looking for something to use in small test projects like game jams or doing proof of concepts.

shut yarrow Oct 10, 2020, 6:00 PM

#

Photon is free for up to 20 concurrent users spread over different rooms. So you could have for example 10 rooms with 2 players each and then you've reached the limit of the free plan

#

For testing it is quite good

woeful badge Oct 10, 2020, 6:02 PM

Awesome, thanks 🙂
I will check it out later tonight

How do you guys go about testing multiplayer games on a single computer? Not being able to open 2 editors for the same project is pretty limiting, and having to build and run every time takes time and doesn't give you easy access to things like the console.

still hare Oct 11, 2020, 4:09 AM

#

I just build it, which is annoying. I wish that Unity had that one Unreal feature that duplicates the editor game window for testing multiplayer. There was some old editor extension for it, but I don't think it works anymore on newer versions of Unity

@frank quiver Thanks, I had actually been using that, but randomly it started throwing errors. I get an error:
APIUpdater encountered some issues and was not able to finish.

Some stuff about not being able to find temp files... and then a dozen errors such as this:
Library/PackageCache/com.unity.inputsystem@1.0.0/InputSystem/Editor/AssetImporter/InputActionImporter.cs(24,42): error CS0246: The type or namespace name 'ScriptedImporter' could not be found (are you missing a using directive or an assembly reference?)

Mlapi - Recommended for - ~64 players

jade glacier Oct 11, 2020, 10:39 AM

#

Pun2 has titles with 64 players and that lists 2-8. That chart and the page it is from are considered a joke among net devs. All of the net options can handle 64 connections. The article is heavily biased toward MLAPI, likely because Unity hired its dev.

#

Having 64 players connect isn't the problem for any transport. The problems come with how much network data 64 players can produce without careful planning, and the CPU costs of schemes required to cull and compress serialization. 64+ requires more skill and knowledge on the devs part.

i'm trying to use photon. But i'm stuckon RPC part. I even copied the code but it still says this.

📎 RPC_shootgun.png

#

here is my code ``` void Update()
{
if (photonView.IsMine)
{
if (Input.GetMouseButtonDown(0))
{
photonView.RPC("RPC_ShootGUN", RpcTarget.All);
}
}
}

[PunRPC]
void RPC_ShootGUN()
{
    RaycastHit2D hitInfo = Physics2D.Raycast(shootpoint.position, shootpoint.right);

    if (hitInfo)
    {
        Debug.DrawLine(shootpoint.position, hitInfo.point, Color.white, 2.5f);
        Debug.Log(hitInfo.transform.gameObject.tag);
        if (hitInfo.transform.gameObject.tag == "Player")

What class are you putting this in? and is this class on the root of an object that has a PhotonView?

#

@lunar plinth

lunar plinth Oct 11, 2020, 4:17 PM

oh wait

#

i forgot photonview

#

b r u h

#

well that worked

#

thanks

#

but now another question how can i know which player is which count

#

like how do i know how player one is player one

#

i need it for score system

jade glacier Oct 11, 2020, 4:55 PM

#

Every connection gets an Player objects, which have an ActorId

#

PhotonNetwork.PlayerList gets you active players

lunar plinth Oct 11, 2020, 5:13 PM

#

but how can i know which player controls which player

#

i mean how do i know who controls actual model

jade glacier Oct 11, 2020, 5:16 PM

#

You are confusing your terms I think

#

Player = connection

#

Your Player as you are describing likely means some PhotonView Prefab you instantiate that is the player avatar

lunar plinth Oct 11, 2020, 5:17 PM

#

i mean i want to check who killed who. I'm really new to all of this tho

jade glacier Oct 11, 2020, 5:17 PM

#

There is no intrinsic connection between the Player (actor/connection) and any particular object.

#

Every PhotonView has a creator, an owner, and a controller.

#

If a PV gameobject kills another gameobject.. then you would look at their PhotonView.Owner

#

Players can own 0-X number of PhotonViews

#

So there is no "Player game object" unless you define one yourself.

lunar plinth Oct 11, 2020, 5:19 PM

#

i just can't wrap my head around it

jade glacier Oct 11, 2020, 5:19 PM

#

Keep at it

#

just realize that player and player objects are not the same

#

Player represents the connection, not a game object.

#

Every gameobject with a PhotonView can have an owner though.
