NPCs

jade glacier Jun 26, 2019, 4:32 PM

#

Or are you actually trying to have every player connect to one another?

empty elk Jun 26, 2019, 4:33 PM

#

Im looking into solutions right now, but am leaning towards forge

jade glacier Jun 26, 2019, 4:34 PM

#

NPCs ideally are handled deterministicly as possible, to avoid having to send piles of transform/animator and such, but depends on the quantites involved, tickrates, need for accuracy, etc

@hard bronze This may help you. This video shows how to use custom types and send misc data as a byte array for photon https://www.youtube.com/watch?v=MP0aGhj6mEs&list=PLkx8oFug638oMagBH2qj1fXOkvBr6nhzt&index=26 and this one shows how to use RPCs https://youtu.be/51W7tnnvzbs?t=306&list=PLkx8oFug638oMagBH2qj1fXOkvBr6nhzt

hard bronze Jun 26, 2019, 6:06 PM

#

Okay, it already work on that path.
But now having problem is, it can't send it to the MasterClient.
It will auto disconnect the Player from the MasterClient due the the file bytes size are too large to send over.

Hello guys,

I found this library. Since I'm new to networking, I'd really appreciate, if somebody with a experience, could take a look at it for me
and tell me if this is good for making an online game in Unity

gray pond Jun 26, 2019, 11:42 PM

#

@copper quartz You could also look at using Mirror, which uses ENet in one of our transports, so you get that protocol with a HLAPI on top
https://assetstore.unity.com/packages/tools/network/mirror-129321

lusty crow Jun 27, 2019, 12:28 AM

#

for large amounts of enemies, what I could see is.

delta compression - only send the data that has changed and be smart about stripping bytes whereever possible
decrease your package send rate, maybe it is enough to send state 5 times per second to keep the players in sync?
if all else fails and there are simply too many units to handle for a standard network bandwith: rts games often still use deterministic lockstep as networking model, which only needs you to send your inputs and an occasional checksum, but it has the restriction that 1. players can't join an active game, and 2. if you run out of sync, you are usually kicked out from the game instance

#

enet is fine from what I have seen, but it depends on how much abstraction you want, if you look something more high level, mirror is pretty good yeah

copper quartz Jun 27, 2019, 10:41 AM

#

how did you guys learn networking?

lusty crow Jun 27, 2019, 11:31 AM

#

reading articles, checking out libraries/frameworks, and experimentation, trial/error.

and some fundamental stuff during education, it is a pretty vast topic

zinc ravine Jun 27, 2019, 2:40 PM

#

how would i go about finding a certain game object with a certain component by its Photon View ID?

📎 unknown.png

fallen apex Jun 27, 2019, 3:16 PM

#

@zinc ravine avoid using FindObjectOfType, its very slow. You can just use PhotonNetwork.GetPhotonView(id)

jade glacier Jun 27, 2019, 3:21 PM

#

If they are all in a resource folder or bundle, that can speed it up

zinc ravine Jun 27, 2019, 4:07 PM

#

@fallen apex

Not exactly sure what you mean though. How would I grab the gameobject OF THAT photon ID?

I want to assign a public game object (weld_parent) TO the object with the ID.

📎 unknown.png

#

i want the null gameobject to Equal the game object found in the scene with that very ID.

📎 unknown.png

fallen apex Jun 27, 2019, 4:18 PM

#

var o = PhotonNetwork.GetPhotonView(id).gameObject;

#

PhotonView is a monobehaviour, so you treat it like any other UnityEngine.Component type and access .gameObject

jade glacier Jun 27, 2019, 4:25 PM

#

You are trying to find all PhotonViews in a runtime scene?

fresh coral Jun 28, 2019, 6:31 PM

Anyone good with names of "game genres" ?
So WoW would be called "open world", the most complete out of all. It tracks each player's quest progression, and can also make instances for dungeons or runs that needs to be entered/finished only once
DragonNest are instance based
Diablo multiplayer is... world-based? Each player's quest prog is tracked but other players can join in and "help" another player's quest
For the diablo one, i wonder if there's some writing about it and how the matchmaking(if any) is tracked, how the quest (in online) is tracked and updated within a multiplayer session, etc

inner acorn Jun 28, 2019, 7:23 PM

#

I wouldn't even call WoW open world to be honest. ^^

#

diablo is more session based

#

It's basically a session with all the data of the person who started the session.

#

and then it plays just like single player only that more characters are on it.

trail parrot Jun 28, 2019, 7:26 PM

#

Diablo's characters are not story-bound at all, right.
Is there a game that has this sorta multiplayer story progression, with say, players playing as Tifa, Aerith, etc during this session?

inner acorn Jun 28, 2019, 7:26 PM

#

you mean taking specific roles?

trail parrot Jun 28, 2019, 7:27 PM

#

So like, exposing the story from other character's point of view, multiplayer RPG

inner acorn Jun 28, 2019, 7:28 PM

#

I think there are some, can't think of a good example right now though.

faint fern Jun 29, 2019, 3:27 AM

#

Looking for some good examples projects for basics on the new unity3D Networking stuff?

#

Does anyone know where I should be looking?

#

@lusty crow Perhaps you might know?

inner acorn Jun 29, 2019, 4:13 AM

#

The new DOTS networking stuff? There is the first person shooter project and the multiplayer example git, but no real good documentation or anything

lusty crow Jun 29, 2019, 5:36 AM

#

there are many projects, you can check out unitylist.com, it is like a register to look for open source projects around unity.

other than that, unity3d networking is a vague description, because you can use a lot of frameworks to do networking in unity,
like necromantic said, there is the fpssample project for the new transport layer in unity, and an approx. 1 hour long video/talk about the project.

but there are other alternatives,
high level and similar to the old UNET hlapi -> Mirror
https://vis2k.github.io/Mirror/
Photon offers some services, but read through the restrictions first, I think most of their products you cannot self host and you are restricted to max 20 concurrent players for the free tier

jade glacier Jun 29, 2019, 5:36 AM

#

The MP lib is a transport last I looked. And the FPS example is a hard coded game - with good practices, but its by no means a generic engine.

lusty crow Jun 29, 2019, 5:37 AM

#

a bit lower level,
there is telepathy - a tcp framework mirror is built upon (but you can change the underlaying communication layer in mirror)
Enet,
and what I personally am gonna use: LiteNetLib

#

@inner acorn

jade glacier Jun 29, 2019, 5:37 AM

#

LiteNetLibManager can bridge the gap if one is inclined to make their own HLAPI

lusty crow Jun 29, 2019, 5:39 AM

#

good input, yeah that project does offer that.

and about the new unity networking layer, I haven't really looked into it, but i know someone who has, it looks like it mostly handles just plain udp transportation, so if you want to have delivery channels among other stuff, you have to build it on top of it, so there is a lot of stuff you would have to do manually.

I hope he will release his library when it is ready though, sounds like it was pretty good

jade glacier Jun 29, 2019, 5:42 AM

#

The main thing everyone gets wrong with networking is thinking its about messaging... but its not. Good networking is about creating the simulation that is conducive to being networked. The main reason I don't actively endorse Unet, Mirror or even PUN (even though I am working with the Exit guys) is that they encourage adhoc messaging instead of driving devs to build simulation systems.

#

https://assetstore.unity.com/packages/tools/network/simple-network-sync-134256 On that note, I actually make assets that try to make better tick-based use of those libraries

#

Not pushing them here, just saying I have some experience in trying to undo the bad practices RPCs and Syncvars encourage.

empty elk Jun 29, 2019, 6:18 AM

#

Ok whats the catch with SpatialOS, I'm taking a look at a bunch of different stuff, and it seems too good to be true

empty elk Jun 29, 2019, 7:03 AM

#

From what i saw from the GDC demo, i could see a bit of desync/lag, im guessing its that combined with high operating cost?

lusty crow Jun 29, 2019, 8:26 AM

#

I assume the price might be a downside, but not sure

#

it seems pretty great for a network simulation with a lot of players

copper quartz Jun 29, 2019, 9:35 AM

#

do you guys know parsec?

#

it opens so many new options

#

for small party games

lusty crow Jun 29, 2019, 9:41 AM

#

parsec is pretty cool, but for games where low latency and good reaction is required, it is not a viable solution imo. Iirc it basically takes your inputs remotely and streams the game of the host back to your system?

vital hawk Jun 29, 2019, 10:58 AM

#

@jovial quail see the pinned message on this channel

#

of course that blog post only covers what Unity is offering

#

there are many 3rd party options too

faint fern Jun 29, 2019, 1:48 PM

#

Thank you @lusty crow @jade glacier and @inner acorn

#

for your replies

#

I have reviewed the code for the fps. It was written pretty much exactly for that situation. To really understand it I'd have to take what feels like the whole project apart and look at it. I've watched the video, I've read the blog posts etc.

faint fern Jun 29, 2019, 2:13 PM

#

The links to third party options are interesting

#

but honestly, I was hoping that there would be more support for things that are part of the unity3d solution itself, because they are going to be around for a while still. All of these other solutions are small teams, sometimes one man teams, that may or may not be here in a couple of weeks.

#

Unless you have a recommendation of something more then that.

inner acorn Jun 29, 2019, 8:47 PM

#

@faint fern As I said, documentation for the new dots networking it is currently pretty bad. Even for someone with networking experience etc. I mean there are tutorials etc. for pretty much all third party solutions and also the unity native ones even if some of those will at some point become obsolete.

Hi guys!
I implemented Photon chat yesterday, but my Boss want I have to send message to server with format JSON.
How can I send text to server with format JSON and get message from JSON with normal string.
Like send {"message":"Hello world"} and get Hello world in chat box.
Please help me. Thanks a lot!

jade glacier Jul 3, 2019, 1:14 PM

#

Because he heard JSON was the hip thing... And decided he wanted it for no real reason?

inner acorn Jul 3, 2019, 5:47 PM

#

Before you go using JSON, read up on how to serialize/deserialize it.

jade glacier Jul 3, 2019, 7:13 PM

#

JSON will be a bit pointless if all you are sending is messages

#

So I would hope he has reason, like intending to send other value or data types on that same message id channel

Number of hops is pretty hard to predict or calculate, so there is no easy answer for typical

a wifi user in an overloaded coffee shop, vs a kid hardwired to a college lan, vs a mobile data user will be wildly different. but I would plan on your game playing reasonably well in the 300ms RTT range as starter

lament bough Jul 13, 2019, 9:12 AM

#

How does Photon differ from Mirror/UNet? From what I've seen Photon provides a third party through which you can set up a multiplayer match, but architecturally speaking does it change anything in the development workflow?

#

I mean, apps developed with the UNet/Mirror framework have all that stuff about being server-authoritative, RPC calls, and the fact that client and server are basically the same project

#

Does Photon change all this?

jade glacier Jul 13, 2019, 2:03 PM

#

Pun users a relay for all traffic, so all clients are aware of other clients and talk to one another through the relay. @lament bough

#

One client is flagged as the master, and can be used as the authority for some things you want it to, but the relay environment adds a hop, so generally you want to treat PUN more like p2p than server/client

lament bough Jul 13, 2019, 2:07 PM

#

@jade glacier thanks for the reply

#

Unity networking still gives me some headaches, I'm used to classic server/client patterns where the server is completely separated from the client but with Unity there's this thing where both are mixed together by design

jade glacier Jul 13, 2019, 3:16 PM

#

Only if you want to make use of Host (server that also has a local client)

#

You can make a standalone server with unet/mirror/forge/bolt

@little turret Not been using photon for a while, but maybe the Rpc method and script has to be on the same gameObject as the one you're sending it to?

little turret Jul 16, 2019, 2:24 PM

#

Im sending the RPC to the other client right? Not to the gameObject

#

Or am i dumb now?

stray scroll Jul 16, 2019, 2:25 PM

#

I can't see where and what script you're sending it from? It's connected to a view no?

little turret Jul 16, 2019, 2:25 PM

#

This script is the Playercontroller on the PlayerObject

#

The playerobject got a Photon View and Transform View

#

the Body object got a Photon view

#

and the body object got the BodyScript with a public variable "head"

stray scroll Jul 16, 2019, 2:26 PM

#

And the gameObject you're sending it to doesn't have this playerController script?

little turret Jul 16, 2019, 2:26 PM

#

No

#

oof

#

First time trying photon/networking

#

If i add the exact same RPC to the BodyScript it doesnt give me that error anymore!

stray scroll Jul 16, 2019, 2:28 PM

#

Neat! : ) And it calls it?

little turret Jul 16, 2019, 2:28 PM

#

BodyScript.sendHeadObject (System.Int32 newbodyID) (at Assets/Scripts/BodyScript.cs:46)

#

and

#

You probably need to assign the head variable of the BodyScript script in the inspector.
UnityEngine.GameObject.GetComponent[T] () (at C:/buildslave/unity/build/Runtime/Export/Scripting/GameObject.bindings.cs:28)
BodyScript.Start () (at Assets/Scripts/BodyScript.cs:15)

#

So the "head" variables is still not assigned

stray scroll Jul 16, 2019, 2:31 PM

#

Uhm, maybe send the bodyScript in some pastebin : )

little turret Jul 16, 2019, 2:31 PM

oh wait

#

stray scroll Jul 16, 2019, 2:32 PM

#

It might be some race thing, that spawn is sent ahead of the rpc

little turret Jul 16, 2019, 2:32 PM

#

I need to pass the "gameObject"'s viewID

#

in the RPC

#

because PhotonView.Find(photonView.ViewID).gameObject; is getting its own gameobject

#

lol

#

    public void sendHeadObject(int newbodyID, int headViewId)
    {
        Debug.Log("Test");
        PhotonView.Find(newbodyID).gameObject.GetComponent<BodyScript>().head = PhotonView.Find(photonView.ViewID).gameObject;
    }```

#

So i guess soemthing like this

#

and then i need to change the reference accordingly

#

oh my god

#

It all works now 😃

#

Thanks!

#

I think i fixed it myself but you made me look at it again 😛

stiff ridge Jul 16, 2019, 3:31 PM

#

A RPC is targetted to a specific GameObject. The one that has the particular PhotonView on it, on which the view.RPC gets called.
So in theory, you don't have to pass a viewID just to "target" the RPC.
It's a different matter, if you want to pass the ID of some related networked object, of course.

Unity multiplayer packages and samples. Contribute to Unity-Technologies/multiplayer development by creating an account on GitHub.

#

# 2019-07-17
## New features
* Added a prefab based workflow for specifying ghosts. A prefab can contain a `GhostAuthoringComponent` which is used to generate code for a ghost. A `GhostPrefabAuthoringComponent` can be used to instantiate the prefab when spawning ghosts on the client. This replaces the .ghost files, all projects need to be updated to the new ghost definitions.
* Added `ConvertToClientServerEntity` which can be used instead of `ConvertToEntity` to target the client / server worlds in the conversion workflow.
* Added a `ClientServerSubScene` component which can be used together with `SubScene` to trigger sub-scene streaming in the client/ server worlds.
* Added a new *Ping-Multiplay* sample based on the *Ping* sample
    * Created to be the main sample for demonstrating Multiplay compatibility and best practices (SQP usage, IP binding, etc.)
    * Contains both client and server code.  Additional details in readme in `/Assets/Samples/Ping-Multiplay/`.
* **DedicatedServerConfig**: added arguments for `-fps` and `-timeout`
* **NetworkEndPoint**: Added a `TryParse()` method which returns false if parsing fails
    * Note: The `Parse()` method returns a default IP / Endpoint if parsing fails, but a method that could report failure was needed for the Multiplay sample
* **CommandLine**:
    * Added a `HasArgument()` method which returns true if an argument is present
    * Added a `PrintArgsToLog()` method which is a simple way to print launch args to logs
    * Added a `TryUpdateVariableWithArgValue()` method which updates a ref var only if an arg was found and successfully parsed```

#

## Changes
* Changed the default behavior for systems in the default groups to be included in the client and server worlds unless they are marked with `[NotClientServerSystem]`. This makes built-in systems work in multiplayer projects.
* Deleted existing SQP code and added reference to SQP Package (now in staging)
* Removed SQP server usage from basic *Ping* sample
    * Note: The SQP server was only needed for Multiplay compatibility, so the addition of *Ping-Multiplay* allowed us to remove SQP from *Ping*
* Made standalone player use the same network simulator settings as the editor when running a development player
* Made the Server Build option (UNITY_SERVER define) properly set up the right worlds for a dedicated server setup. Setting UNITY_CLIENT in the player settings define results in a client only build being made.
* Debugger now shows all running servers and clients.```

#


## Fixes
* Change `World.Active` to the executing world when updating systems.
* Improve time calculations between client and server.
* **DedicatedServerConfig**: Vsync is now disabled programmatically if requesting an FPS different from the current screen refresh rate
## Upgrade guide
All ghost definitions specified in .ghost files needs to be converted to prefabs. Create a prefab containing a `GhostAuthoringComponent` and authoring components for all required components. Use the `GhostAuthoringComponent` to update the component list and generate code.```

Heyo. I need help with syncing variables for Photon Unity Networking.

I am trying to sync a variable that is constantly changing, as in per frame. The variable starts to change when a player is near a certain object. The variable increases, and will increase quicker if more players were to be near it. How do I sync this accurately with every player without any sync issues?

still atlas Jul 19, 2019, 11:46 AM

#

if u want to sync values multiple times every frame in photon you need to serialize values.You do this in function OnPhotonSerializeView. Here is a working example: https://stackoverflow.com/questions/30874161/how-could-i-use-onphotonserializeview

winged musk Jul 19, 2019, 5:16 PM

I'm looking for thoughts on how to manage simple statistics on a per level basis for a project that I'm currently brainstorming for.

What I need to track are the XY coordinates of players per level (only once per level) on a low-res level (like maybe 10x10 grid), like a 2D histogram more or less. Players will need to be able to read and write these values. As an example, think of how Mario Maker shows the positions of each player death per level.

I was looking into whether I could leverage something like Playfab or Firebase. However, from a high level overview of those services, I'm not sure if they are suitable. Maybe Firebase since it now has an increment method which help eliminate race conditions of players writing to the same XY space. But Firebase seems to really be for mobile whereas I'm looking to do this on desktop.

Any suggestions?

I'm cross posting this with #💻┃code-beginner

you want a live feed of all players in a level?

winged musk Jul 19, 2019, 5:26 PM

Doesn't necessarily need to be live. Kind of a database

fading pawn Jul 19, 2019, 5:27 PM

well they move so do you want their most recent position or just death locations for example

winged musk Jul 19, 2019, 5:27 PM

#

Just the death location. So after a player dies, the previous deaths can populate on screen

#

Don't need to see any players actively playing through levels

You probably need some combination of CloudScript and Entities, I would ask on the PlayFab forum

Firebase might be more straightforward

@opaque dew Because I used PUN v1 about a year before v2 was officially released, so I'm too used to v1 than I am with v2.

opaque dew Jul 19, 2019, 6:19 PM

#

oh. there's hardly any difference between the two. the main difference is that v1 simulates unity api while v2 c#.

#

eg: v2 uses overrides and interfaces while v1 uses reflection

#

it may not actually be reflection, I havent looked into it deeply, but behaves similarly. v2 is also better in the sense you cannot screw up methods via typos like you can in v1.

Please suggest any other networking system which can help me.

lusty crow Jul 20, 2019, 6:29 PM

if it is only an offline game, you don't really need a network library, just make sure that you can have multiple inputs for multiple players

weak plinth Jul 20, 2019, 6:54 PM

#

I can definitely vouch for TNet - ever sense I tried it I fell in love with it. But it isn't a cloud solution rather it allows people to host their own dedicated servers. How you deal with connecting the players is up to you I suppose. But there's no fees involved with it and can host as many players as your machine can handle depending how you optimize bandwidth, etc.. But TNet can certainly do LAN gaming. Comes with full source code too.

@drifting meadow Unet and their services are deprecated. You can use Mirror or other networking solutions though to run a dedicated server for hosting your own games and back-end services. Which solution depends on what fits your game and needs.

What is the better approach in networking UI Windows, such as inventory, crafting window, character window etc. Place the UI window in the scene and create logic in scripts that only local player can use the window, or Instantiate clones of UI Windows prefabs for each client? Also im using Photon PUN.

jade glacier Jul 28, 2019, 6:03 PM

#

you never network UI

#

the best approach to any networking is to reduce your game to tick based states

#

PrevState + UserInputs = NextState over and over

#

you serialize when possible only user inputs and or state values

#

UI should be getting notified of state changes with callbacks locally

#

or the UI checks the values it is monitoring on regular intervals, that is more up to you

#

But the actual UI <-> data connection should have nothing to do with networking

Hey guys, I've been learning PUN2 and am looking to make a test demo game similar to the old Crossfire game: https://www.youtube.com/watch?v=rCwn1NTK-50
I'm trying to figure out the best way to handle the physics sim/sync between the balls hitting each other. Photon Quantum costs too much, so I'm looking at setting it up as best as I can with PUN2.
One thing that I imagine would make networking the physics a bit easier with this game is that the players can't effect the balls after they are fired, which I'm hoping will help concerning the non-master client predicting the collisions. I was thinking that maybe all of the balls would be 'owned' by the Master Client, instead of having Player 2 'own' the balls that they shoot.
Anyone have any tips or suggestions? 😄

idle vine Jul 29, 2019, 5:19 PM

#

@oak flower Do you have an example of adding data rather than just a form but raw POST?

#

when we do a test via lua, browser, or even post simulator it works fine, but unity just gives us an OK and the server says it got the post but part of the data is nothing fed correctly or even returned

#

but we are passing variables not forms within unity

#

or could one take this:

        WWWForm form = new WWWForm();
        form.AddField("myField", "myData");

and then have

string apikey = "foo";
string  gold = "moo";
WWWForm form = new WWWForm();
form.AddField(apikey, gold );

oak flower Jul 29, 2019, 5:30 PM

#

It doesn't change the nature of the string. Check that you expect the right fields

idle vine Jul 29, 2019, 5:34 PM

if we did it that way... it should in theory do a communication without srambling the post into json or something like that?

UI should not be networked. You can do anything you want, but that is about the most entangled you could possibly make your simulation, data and UI

#

three things that you want COMPLETELY abstracted from one another for any sane networked project @weak plinth

weak plinth Jul 30, 2019, 9:53 PM

#

@jade glacier That is why i'm looking for a way to separate UI. If i just set any UI object in the scene without any networking scripts my clients still share that UI object. Every time a new client opens the scene all UI resets to start point across all clients

jade glacier Jul 30, 2019, 9:53 PM

#

You generally want your UI totally separated from the data anyway

#

a typical patter is data is just data, but it has properties, so you change values through those... and those fire callbacks to anything monitoring that data value

#

So you would have UI subscribe to UI events for that data

#

Networking -> Passes State value to buffer
Tick pulls state from buffer and Sets Data Property

#

Property Generates OnChanged event

#

UI responds to OnChanged event

I'm currently working on an AR app that downloads an assetbundle containing a few mp4 files. Using UnityWebRequest.Get(url) since it still allows me to access the request.downloadHandler.data as bytes[] to save as a file in the phone.

But I ran into a bug regarding a way to show the download progress.
The DownloadHandler.downloadProgress value smoothly goes from 0 to 0.99 in my editor when I am downloading something, but once I am on the built version on my phone. The downloadProgress value starts at 0.5 instead of 0 and constantly loop back to 0.5 after reaching 0.99. Is there any reason why is that happening?
Edit: To be clear, the download is going through, but the progress feedback is not working properly in Android.


public IEnumerator GetBundle()
{
    UnityWebRequest request = UnityWebRequest.Get(uri);
    request.SendWebRequest();

        while (!request.isDone)
            {

i have a simple question, I'm using Photon. Well I detect collision with an object, when that happens I take it out some lifepoints. I know that this function is played since the log "entering hitvehicle" is shown in console, but "taking out 1 hp" is never shown, as well as the debug in die function, even after enough shots to theoreticaly destroy the object. Any idea ? (the object has 2 hp and the damage given is 1)

I suppose you could run a client in headless mode to act as the server, but out of the box it's client auth.

@halcyon vessel The photonView must not be yours then.

If the object is placed in the scene its owned by the master (unless you change it manually). If its spawned, by default its owned by whoever spawns it.

Quick question - using PUN2: Players have a gun that shoots balls. The game starts with the balls on the ground and the player has to pick up the balls to add them to their guns "clip" and then can fire them. Instead of destroying the BallObject when the player picks it up, and instantiating a new one when the player shoots it, I'd like to just keep the ballObjects in the scene at all times.

My question is how to handle what happens to the ball (visually + physics) when the player picks it up off the ground. I'd like for it to just disappear, but I don't think I can setActive(false) to the ball, since it needs to be ready network-wise to be fired from the gun. (AKA if it was set to inactive and Player 2 received an RPC that it was fired from Player 1's gun, the BallObject would be inactive so it wouldn't process anything)

Is there a way to just temporarily disable the visuals of the ball, and remove it from the physics simulation? Like... a crude solution would be to just hide the ball underneath the ground until it is fired, but I'd prefer not to do that if theres a better way 😉

#

Honestly this may not even be a networking question now that I think about it 😝

#

Whelp, I guess I should have tried the rubber ducky approach before typing all of this out - I think I can just set the Physics Layer to one that doesn't collide with anything, and then set the MeshRender.enabled = false

jade glacier Aug 2, 2019, 8:59 PM

#

You will still have to sort out where authority lies/remains/changes, and how to deal with the desync due to latency. The classic problem being what happens if two players grab a ball at the same time.

#

@nimble grove

nimble grove Aug 2, 2019, 9:22 PM

#

Thanks @jade glacier, I'm making a game similar to the old board game Crossfire, so the players can only pick up the balls in their own area

I don't know what happened with my project, but 2 hours ago it suddenly just started lagging. The balls in the game have their PhotonTransformView and a PhotonRigidbodyView attached to their normal Photon View. I've been working on this project for a couple days, and it was running amazingly smoothly with 20+ balls and the physics simulation was working great (basically the master client was running the show). It looked great on both master client and the non-master client.

The balls are now jumpy (on the non-master client only), even when they are just rolling slowly in a singular direction with nothing else effecting them. Almost as if the transform was being updated but not the velocity. I created a new empty Scene and created a new Ball prefab that is literally just a sphere with the Photon View components attached. Its STILL laggy, with absolutely nothing else even in the equation.

Are there any project settings that could be effecting this? I played around with the Quality/Graphics settings, but havent touched anything PUN related as far as I know. I also tested an online game so I know its not just my network being laggy. I've restarted my computer/etc

jade glacier Aug 2, 2019, 9:29 PM

#

Laggy might need better definition, it has like 5 different meanings in game making

nimble grove Aug 2, 2019, 9:30 PM

#

(and fwiw I've read the entire Pun documentation and done multiple test/practice projects so I'm not 100% noob)

#

ball is rolling in a straight line at medium speed -> on non-master client it teleports forward 4 or 5 times every second, and its speed appears to be slower

jade glacier Aug 2, 2019, 9:31 PM

#

that would be hitchy, not so much laggy

nimble grove Aug 2, 2019, 9:31 PM

#

ah, haven't heard that term

#

yeah, its almost like the velocity is wrong

#

if the velocity was correct it wouldn't be jumping forward (since it'd be in the correct place)

jade glacier Aug 2, 2019, 9:32 PM

#

laggy is used for everything from input lag, to network latency, to hitching, to jerkiness, to anything else not smooth or immediate... so you mostly need to isolate WHAT exactly is not right

#

because that will tell you were to look

#

I have no idea how you are syncing things either, so it may be a problem with your controller fighting with the networked transform. Might be that your particular transform sync is trying to move an RB but that RB isn't kinematic and needs to be....

right now its literally a scene where two players join a room (nothing else happens there), and then switch to another scene with game board (just static 3d objects) and the master client PhotonNetwork.instantiates a couple of these balls

jade glacier Aug 2, 2019, 9:36 PM

#

I just suspect that its something to do with the transform sync and rb fighting one another or your settings

nimble grove Aug 2, 2019, 9:36 PM

#

are there any photon network "project settings" somewhere?

#

the transform view syncs the transform, the rigidbody syncs the velocity

#

they're meant to work together

jade glacier Aug 2, 2019, 9:37 PM

#

That's going to be more how your RB is set up, and what the correct usage of those two components together is.

#

https://assetstore.unity.com/packages/tools/network/simple-network-sync-134256 I personally use my own, so I never really touch their defaults

#

But the concepts are probably similar

#

I generally don't ever encourage trying to sync physics

#

without a tick based or deterministic system, that's going to usually just result in a mess and a lot of data. Have you tried just making the objects rb.isKinematic = true on all instances that are not the authority version?

#

and moving with transform sync?

nimble grove Aug 2, 2019, 9:39 PM

#

i understand, but the fact of the matter is that it was working amazingly well up until a couple hours ago

jade glacier Aug 2, 2019, 9:39 PM

#

A setting changed somewhere, do you have an old git you can pull up and see what changed?

nimble grove Aug 2, 2019, 9:39 PM

#

and as far as i know i did nothing to change it besides mess with some stuff in the Project Settings (mainly graphics)

jade glacier Aug 2, 2019, 9:40 PM

#

graphics shouldn't affect that

nimble grove Aug 2, 2019, 9:40 PM

#

project is so new I might as well just start from scratch

#

just frustrating that it was working so well, and now even with all other factors removed, its acting screwy

#

like... its gotta be some project setting or something

jade glacier Aug 2, 2019, 9:43 PM

#

could just be a race condition exposing itself, for some odd reason like component order or god knows what

nimble grove Aug 2, 2019, 9:43 PM

#

yeah, i remember reading about component order mattering for a certain thing with Pun, but couldn't find it

jade glacier Aug 2, 2019, 9:43 PM

#

It very likely will with those two components

nimble grove Aug 2, 2019, 9:44 PM

#

yeah i guess i'll mess with them some

jade glacier Aug 2, 2019, 9:44 PM

#

the default components have no deferment, they are very simplistic

nimble grove Aug 2, 2019, 9:44 PM

#

thing is, i 100% did not do anything with the two Observed Components

jade glacier Aug 2, 2019, 9:45 PM

#

That's the nature of race conditions... if its not hard defined anything can tip the balance wherever its not hard coded as deterministic

nimble grove Aug 2, 2019, 9:46 PM

#

hmm yeah, but aren't the components updated in-order? I didnt change their order

#

ill mess around with the 3 main photon view related components and see if anything happens

jade glacier Aug 2, 2019, 9:46 PM

#

The order is deterministic, but what happens inside of those in relation to the rb simulation... no idea

#

Not sure how they are coded specifically, I just know the defaults have no real deferment or simulation... so without going in and debugging, no clue.

#

it may not even be them, it may be your controller is fighting them.

nimble grove Aug 2, 2019, 9:47 PM

#

thats the thing, this new scene i made has no controllers

#

it literally has nothing

#

except a couple balls that fall down and roll

#

and the balls have photon view components

#

i mean, the balls are instantiated from a script, but nothing besides that

jade glacier Aug 2, 2019, 9:48 PM

#

you are on PUN2 the latest and all I assume

nimble grove Aug 2, 2019, 9:48 PM

#

the script does nothing else

#

yeah

#

well, not the unity update that came out a couple days ago

jade glacier Aug 2, 2019, 9:48 PM

#

also, are you sure you are supposed to use both?

nimble grove Aug 2, 2019, 9:48 PM

#

yeah

jade glacier Aug 2, 2019, 9:49 PM

#

and your interpolation settings are set so the two aren't fighting to interpolate?

#

sync RB is automatically suspect for me, because that means moving the object with physics on all clients, and hard setting the transform as well.... There is no way that is going to be pristine how PUN fires its updates in LateUpdate()

nimble grove Aug 2, 2019, 9:50 PM

#

the Transform View and Rigidbody View for pun 2 don't have any interpolation/advanced settings

jade glacier Aug 2, 2019, 9:51 PM

#

a good smooth sync would require some luck on the timing of your updates lining up well

nimble grove Aug 2, 2019, 9:51 PM

#

the RB sync is velocity only

jade glacier Aug 2, 2019, 9:51 PM

#

yeah, but velocity means non-kinematic

#

on all dumb clients

#

you are moving with forces there... and you are at the same time trying to move an RB with transform.position as well

#

There is no sane way to make the parts in play add up to a good smoothed out sync

nimble grove Aug 2, 2019, 9:52 PM

#

i see what youre saying - im not applying any forces except that the balls drop from above

jade glacier Aug 2, 2019, 9:52 PM

#

Doesn't matter, the syncRB is velocity based

nimble grove Aug 2, 2019, 9:52 PM

#

(for this stripped down test to figure out whats going on)

jade glacier Aug 2, 2019, 9:53 PM

#

unless that thing is doing interpolation internally, I suspect its trying to set velocity

#

on the RB

#

easier for me to just open the file and look here

nimble grove Aug 2, 2019, 9:54 PM

#

well, im not a mega expert on it, but until a couple hours ago everything looked pretty much perfect on the client's side

#

including multiple balls colliding/getting clustered up

jade glacier Aug 2, 2019, 9:54 PM

#

its applying the networked values in fixedupdate, and is moving its position

#

I don't see this as being compatible with TransformView

nimble grove Aug 2, 2019, 9:54 PM

#

moving its position too?

jade glacier Aug 2, 2019, 9:55 PM

#

{
    if (!this.m_PhotonView.IsMine)
    {
        this.m_Body.position = Vector3.MoveTowards(this.m_Body.position, this.m_NetworkPosition, this.m_Distance * (1.0f / PhotonNetwork.SerializationRate));
        this.m_Body.rotation = Quaternion.RotateTowards(this.m_Body.rotation, this.m_NetworkRotation, this.m_Angle * (1.0f / PhotonNetwork.SerializationRate));
    }
}```

#

That is what it is doing

#

rb.position =

#

Its not doing anything with velocity, other than coming up with positions

#

I don't even see interpolation code

nimble grove Aug 2, 2019, 9:56 PM

#

lol, im opening it

#

to look as well

jade glacier Aug 2, 2019, 9:56 PM

#

I would advise against using that component, its is bare bones sample code

#

its applying velocity as it receives it

#

its not buffered

nimble grove Aug 2, 2019, 9:57 PM

#

isn't it setting the velocity in OnPhotonSerializedView?

jade glacier Aug 2, 2019, 9:57 PM

#

didnt even notice that, because I didn't expect to see it doing that

#

yeah, it is

#

so that is also very not compatible with anything

#

but regardless.. it is hard setting a position in Fixed

#

so its going to be fighting with TransformView

nimble grove Aug 2, 2019, 9:58 PM

#

ok lemme try without transform view

jade glacier Aug 2, 2019, 9:58 PM

#

I don't see how these two can be meant to work together at the same time.

nimble grove Aug 2, 2019, 9:58 PM

#

I agree - but i read in at least 2 places that you're supposed to use both (they might have been wrong)

#

i mean, based on what you just said... they were wrong it seems

jade glacier Aug 2, 2019, 9:59 PM

#

Unless that came from the PUN team, I would ignore most internet advice on this stuff. 1% of the people using PUN understand PUN

nimble grove Aug 2, 2019, 9:59 PM

#

Im starting to think that it did not, lol

jade glacier Aug 2, 2019, 9:59 PM

#

I am working with Exit right now on building components... I don't know what theirs do - but I know tranform syncing pretty well

#

Tobi is the first to admit that their Transform and RB syncs are just starter code and has never been a focus, same as UNet, Mirror and Forge.

#

for all of the HLAPIs you really have to build your own and buy a third party asset

#

I literally work on this stuff, and I couldn't even tell you the right answer until I looked.

nimble grove Aug 2, 2019, 10:01 PM

#

youre a God!

jade glacier Aug 2, 2019, 10:02 PM

#

working better now?

nimble grove Aug 2, 2019, 10:02 PM

#

yes

jade glacier Aug 2, 2019, 10:02 PM

#

cool

nimble grove Aug 2, 2019, 10:02 PM

#

fk

#

lemme re-enable my main stuff

#

if this fixed it i owe you a pizza or something

#

just send your address to me, a stranger on the internet

jade glacier Aug 2, 2019, 10:02 PM

#

If you find it coming up short, you may want to check out the asset above - but only if its failing you

#

My asset is slated to become part of PUN2 down the road, but that timeline is very unclear atm

nimble grove Aug 2, 2019, 10:03 PM

#

ooo ill check it out

jade glacier Aug 2, 2019, 10:03 PM

#

Or don't - its a paid asset so I don't mean to sound like I am pushing it

#

just letting you know it exists

nimble grove Aug 2, 2019, 10:04 PM

#

oh nice, animator syncing too

#

I've been wondering about that - I'm coming to Unity from 5 years of working with Libgdx, and I used the 2D animation program Spine a lot

#

If I made a 2D game, I've been wondering how to handle syncing the animations

jade glacier Aug 2, 2019, 10:05 PM

#

The animator is a pain to sync, but the Unet and PUN syncs do a pretty decent job

#

my animator sync is like 4000 lines of code, there are a lot of permutations once you start building in compression schemes

nimble grove Aug 2, 2019, 10:06 PM

#

yeah, I wonder if Spine's unity setup has some integration with unity's animation stuff

jade glacier Aug 2, 2019, 10:06 PM

#

I would expect not 😃 Being Unity and all

nimble grove Aug 2, 2019, 10:06 PM

#

i think i read about it having some mechanim implementation or something (im still new)

#

lol yeah probably not, i just remember reading about some integration aspect that worked with one of Unity's animation controllers or something

jade glacier Aug 2, 2019, 10:07 PM

#

I actually know very little about the Animator landscape - my only focus was on syncing all of the things that could be synced in it

#

The Animation Controllers are really what is being synced

#

heading off, hopefully you are all good now

nimble grove Aug 2, 2019, 10:09 PM

#

thanks again dude!!

nimble grove Aug 2, 2019, 10:33 PM

#

For anyone reading, after playing around a bit further this is my final setup:

Photon Transform View: Use this only for Rotation (uncheck Position)
Photon RigidBody View: Use this for Position (automatic) and Velocity (checkbox). Can also use for Angular Velocity

Using PUN2: Is there any way to get the ping between clients (namely between the masterClient and others)? I see that there is a built in way to get ping to the Photon Servers themselves, but can't find anything about ping between players. Do I need to implement it myself with an RPC?

nimble grove Aug 4, 2019, 11:50 PM

#

Alright, I was able to calculate ping using an Event and PhotonNetwork.Time

weak plinth Aug 6, 2019, 1:00 PM

Hey

I am using public override void OnPlayerEnteredRoom(Player newPlayer) to know if a player has joined a room, but this callback doesn't occur when the room is first created and the master is joining it. Is there another way to determine who are the players in a room ?

hello, anyone familiar with WebSockets? those from System.Net namespace. I couldn't find any topic that is related to my issue: opened socket throws the "The remote party closed the WebSocket connection without completing the close handshake." on ReceiveAsync call in unity frequently, while the very same code launched through regular C# console application executes without a single error per same amount of test calls. (All test calls are consecutive, and all are awaited before next one will be executed)

#

Before moving to the other socket libraries I would prefer to confirm if any bugs exists with system ones, because I like async\await approach more than event model which somehow other libs prefer.

cyan mango Aug 11, 2019, 12:42 PM

hi guys, my team is working for the first time on an online project, and we are using photon networking, I had a question about how it works because one of the programmers was asking how can we handle lost packets due to a bad connection, when players hit a monster, that monster will target the player and start attacking him, but we were thinking if there was 2 players that attacked the monster at the same time, 1 had a bad connection so he missed the packet saying that the monster was attacking player 1 , so on one player's screen it might look like the monster is attacking player 1 and on the other player's screen it might look like the monster is attacking player 2, but since it's online, the monster should be doing the same action for both players, how can we handle if a packet was lost in this way?

past wren Aug 11, 2019, 12:46 PM

#

^ FYI to answer your question about photon. There is 2 i believe
Photon PUN and Photon BOLT.

Bolt is a higher level API (Used for like MMO servers etc)
Pun is a bit like Unet

graceful zephyr Aug 11, 2019, 12:49 PM

#

@past wren Bolt is not for MMO servers.

cyan mango Aug 11, 2019, 12:50 PM

#

my lead programmer suggested that monsters need permission from the master client (run on the server) before they can take any action, so if the master client already gave permission to a monster to attack a certain player then if another request comes from a lagging player to make the monster attack a different player then it will reject it

past wren Aug 11, 2019, 1:18 PM

#

Why would you not use bolt for MMO? "BOLT offers truly unique support for authoritative games" Isn't an MMO an authoritative game (IE the clients are dumb and server rules with an iron fist)

cyan mango Aug 11, 2019, 1:32 PM

#

our programmers have only used photon realtime before but I will definitely look into bolt to see if it's more useful

weak plinth Aug 11, 2019, 1:43 PM

#

That seems a bit expensive though

graceful zephyr Aug 11, 2019, 3:58 PM

#

@past wren considering I made bolt, I'm pretty sure it should not be used for mmos lol

past wren Aug 11, 2019, 3:59 PM

#

I wasn't disputing what you said, just asking why it wouldn't be suitable when it states it offers authoritie game support.

weak plinth Aug 11, 2019, 4:06 PM

#

because its max plan is 2000 ccu ?

#

xD

#

and probably laid out for smaller "lobbies"

vernal remnant Aug 11, 2019, 4:22 PM

#

Bolt seemed to be a session based authoritative result of master host (COD/BF type games i think)

If you were making a game with a long lifetime you would want to program up your own server alongside the client; at least for an MMO, if you were interested in the development process yourself it would also be feasible to do so.

weak plinth Aug 11, 2019, 4:24 PM

#

yeah because u dont have to pay monthly for bolt then 🤑

vernal remnant Aug 11, 2019, 4:25 PM

#

Another solution for MMO's would be spatial

#

Their costs are questionable though for a small team or small game

weak plinth Aug 11, 2019, 4:26 PM

#

thats why i make my game small in networking code and not mmo for now 😂

#

you have to think about so many things in an mmo

vernal remnant Aug 11, 2019, 4:27 PM

#

ye but a lot of fun to make

weak plinth Aug 11, 2019, 4:27 PM

#

tru i tried some "mmo" stuff before with "areas" and stuff

#

its fun to experiment with and test performance

#

but i never got to more than that . just some position and rotation stuff

#

this small one will have more stuff sent but in a small lobby scale 2-4 players

solar garden Aug 12, 2019, 10:50 AM

#

What networking solution would be the best choice for a fast paced fps with a dedicated server setup, authoritative movments, client prediction etc...

jade glacier Aug 12, 2019, 5:45 PM

#

Photon Bolt @solar garden

#

Its literally for just that

#

Hosting it with a dedicated I am not sure the process, since its tied to PUN now, but self-hosting is still an option as far as I know. Best to ping their channel though for details.

solar garden Aug 12, 2019, 5:48 PM

#

i was thinking more of the middle level frameworks like litenetlib, enet, mirror...

jade glacier Aug 12, 2019, 5:48 PM

#

Then all that you just described doesn't apply

#

those are all messaging layers

#

Server setup will be in your hands, but nothing relating to server auth/ prediction are part of them. You have to write all of that yourself.

solar garden Aug 12, 2019, 5:50 PM

#

Yes i am aware but one must be easier to work on for this kind of setup right ?

jade glacier Aug 12, 2019, 5:51 PM

#

The question itself implies a bunch of things that I think indicate a wrong approach

#

its really two questions

#

Any discussion about server authority with client prediction has little to nothing to do with the messaging layer

#

that is all about creating a tick based simulation and reducing your game to inputs and states on that tick

#

That solution doesn't care about your messaging layer

#

None of them do anything for you in relation to making that, the only exception being Bolt, which is the only full stack solution.

#

The transport layer is more about how your want your stuff hosted, and the protocol you want to use for messaging.

#

But the messaging is nothing more than sending your inputs and states between machines. It has no concept of or interaction with your simulation.

solar garden Aug 12, 2019, 5:57 PM

#

i know all of this but i have been stuck for ages because of all the things you have to account for like tick system, input redundancy, client prediction etc...
i though i just didn't used the right framework thats why i was asking if there was a framework better suited for this setup with maybe a doc

jade glacier Aug 12, 2019, 5:58 PM

#

None of them are conducive to tick based sims other than Bolt and Quantum sorry. In the case of Mirror/Unet/PUN2 they actively encourage the opposite

#

as their tools are all inherently ad hoc time based

solar garden Aug 12, 2019, 5:58 PM

#

i kind of get the system but i can't get miself around this notion

jade glacier Aug 12, 2019, 5:58 PM

#

Its the hardest part of networking, few touch it because its not something you just dabble in

#

you have to do it 100% right or you are just making garbage that is going to tie you in knots

#

Bolt is the only one that does it because fholm took two years to make it

#

And it requires you to make the entire stack

solar garden Aug 12, 2019, 6:00 PM

#

but bolt isn't free and requier to rent photon servers right ?

#

you can't host on your pc

jade glacier Aug 12, 2019, 6:00 PM

#

I built a deterministicy PhysX server auth setup with client prediction, but never shared it are released it because it requires SO much manhandling of everything, from input sampling to the Character Controllers to the Physics ticks.

#

I don't know the details of the financial model of Bolt, you will have to ask them for that

#

I'm just saying it is the only box solution for that. Other than that you are going to need to get your hands dirty and learn all of this stuff for real.

solar garden Aug 12, 2019, 6:01 PM

#

i understand

#

what did you meant when you said that the transport layers are ad hoc ?

jade glacier Aug 12, 2019, 6:02 PM

#

sendrate =

#

There is no inherent simulation based tick core to them

solar garden Aug 12, 2019, 6:03 PM

#

you mean they dont have a tick system ?

jade glacier Aug 12, 2019, 6:05 PM

#

Nope, nor any hooks that make making your own play nice with their HLAPI code

#

for example Mirror's SyncVars and OnSerialize methods are all based on the sendrate for that component

#

So there isn't any inherent sense of deterministic serialization order that you can have those state syncs fire post simulation, nor have a way to identify when those syncs happen what tick they happened on.

#

So you can't tie them into a ring buffer system in any way

#

making them useless for tick based rewind and resim

solar garden Aug 12, 2019, 6:07 PM

#

ohh that sux

jade glacier Aug 12, 2019, 6:07 PM

#

It just is what they are

#

they aren't meant for advanced tick based deterministicy sims

#

they are meant for the most basic form of state sync, which is all most new networking people care about.

#

but they break quickly if you try to start applying advanced concepts to them

solar garden Aug 12, 2019, 6:09 PM

#

Ok good to know

#

what about exotic frameworks like Racknet or even Sockets

#

well no not sockets

jade glacier Aug 12, 2019, 6:10 PM

#

Again... those are messaging layers

#

Not tick based simulation systems

#

You can network your game with email if you want

solar garden Aug 12, 2019, 6:12 PM

#

Yes but the problem with unet, mirror, telepathy... is that they are all based on the same core preventing the use of a tick system, but they aren't so isn't it a solution

#

haha funny concept

jade glacier Aug 12, 2019, 6:12 PM

#

They don't prevent it

#

they just make no efforts to support it

#

Simple Network Sync - Asset Store

A more robust component system for syncing Transforms and Animators with UNET and Photon PUN2. (Mirror is not officially supported, but currently is compatible)

Documentation

Aggressive Compression Options

Range-based float compression, bitpacking, and key/delta ...

#

But I don't use ANY of their HLAPI outside of the NetIDs

#

All of the libs let you send byte[] messages, and that is all you are really going to be doing

#

I made that to run on Unet and PUN2 both, which is possible because it ignores all of their adhoc stuff and just does it all on its own update manager timings

solar garden Aug 12, 2019, 6:13 PM

#

oh then its ok then just incredibly hard

jade glacier Aug 12, 2019, 6:14 PM

#

More time consuming than anything

#

The concepts aren't that hard

solar garden Aug 12, 2019, 6:14 PM

#

they aren't yeah but somehow they are

jade glacier Aug 12, 2019, 6:14 PM

#

separate your game from the networking. Your game needs to be reduced to tick based states. Similar to PhysX

#

State[x] + Inputs[x] = State[x+1]

#

unless you have that working, any networking is going to just be spinning your wheels

#

For advanced stuff, like client prediction, rewind, resim etc

#

Use networking just to share inputs and state results

solar garden Aug 12, 2019, 6:16 PM

#

like just for the sending ?

#

the rest is all me

jade glacier Aug 12, 2019, 6:17 PM

#

yup, networking is nothing more than sending and receiving byte[]

#

All of the libs are JUST that

#

They try to hide it from you, but that is all they are doing

solar garden Aug 12, 2019, 6:18 PM

#

i guess at this state even Sockets would be enough heh

weak plinth Aug 12, 2019, 6:18 PM

#

i use sockets for my 2d coop game

jade glacier Aug 12, 2019, 6:18 PM

#

The transport layer has more to do with the hosting environment, platforms you will be on, and the protocol you want (udp vs tcp)

#

you REALLY have to separate the two in your head

weak plinth Aug 12, 2019, 6:19 PM

#

used litenetlib once before but i didnt like it

jade glacier Aug 12, 2019, 6:19 PM

#

the transports should be abstracted entirely

weak plinth Aug 12, 2019, 6:19 PM

#

i like making it myself tho so thats personal

solar garden Aug 12, 2019, 6:20 PM

#

you dont have some tick system or server side simulation and all that jazz ?

jade glacier Aug 12, 2019, 6:20 PM

#

I do in my personal lib

solar garden Aug 12, 2019, 6:21 PM

#

what is it based on ?

jade glacier Aug 12, 2019, 6:21 PM

#

2 years of me writing code

solar garden Aug 12, 2019, 6:21 PM

#

yeah but don't it use some base like sockets ?

One of the tests of my giant mess in action

📎 2019-04-18_00-29-08.mp4

#

It is abstracted. I was using UNet or PUN2 for the test, but it doesn't matter

#

Asking me which protocol is like asking which email server we use to run our company... its incidental and unimportant

solar garden Aug 12, 2019, 6:22 PM

#

i dont even know how to do the network traffic gui lmaoo

#

ohhh

weak plinth Aug 12, 2019, 6:23 PM

#

what is your goal ?

solar garden Aug 12, 2019, 6:23 PM

#

me ?

weak plinth Aug 12, 2019, 6:23 PM

#

Yes!

solar garden Aug 12, 2019, 6:24 PM

#

I would like to have a dedicated sever setup

#

basically a 1:1 recreation of what you could have in csgo

jade glacier Aug 12, 2019, 6:24 PM

#

The question being do you want to become an ace level networking guy, or just get your game done?

#

Because if you just want to get your game out - just go look into Bolt... it LITERALLY is for that use case.

weak plinth Aug 12, 2019, 6:25 PM

#

cs:go servers are not flawless btw

jade glacier Aug 12, 2019, 6:25 PM

#

If you want to start a career as a game net dev - then set aside two years

weak plinth Aug 12, 2019, 6:25 PM

#

saw someone do a defuse hack where he defused the bomb instantly

solar garden Aug 12, 2019, 6:25 PM

#

being an ace level networking guy would be a blast tho

jade glacier Aug 12, 2019, 6:26 PM

#

Then set aside two years, and half a dozen attempts to make your own system

#

And forget your game

solar garden Aug 12, 2019, 6:26 PM

#

thats faulty entity code its nothing

#

valve is lazy

jade glacier Aug 12, 2019, 6:26 PM

#

CS was also made quite a while ago, net code best practices have evolved quite a bit since then

solar garden Aug 12, 2019, 6:27 PM

#

really ?

jade glacier Aug 12, 2019, 6:27 PM

#

But even the best like Overwatch still have ghosts, because the internet is a noisy lossy mess.

solar garden Aug 12, 2019, 6:27 PM

#

i think cs is pretty tight

jade glacier Aug 12, 2019, 6:27 PM

#

The main voodoo of networking is learning how and where to hide the latency artifacts

#

everything is in desync, and you have to bend reality to make it seem like they are all in sync to the user

weak plinth Aug 12, 2019, 6:28 PM

#

but then stuff gets bad at places which you don't notice as easily

solar garden Aug 12, 2019, 6:29 PM

#

physics is the main problem

#

dont you have some sources to read ?

#

i feel like i have seen everything on the internet i think i didn't search right

weak plinth Aug 12, 2019, 6:30 PM

#

just do it yourself trust me

#

start with some sockets

#

maybe try out a lib

solar garden Aug 12, 2019, 6:31 PM

#

trying is the way to go as always right ?

weak plinth Aug 12, 2019, 6:33 PM

#

well do what you want basically

solar garden Aug 12, 2019, 6:33 PM

#

oh boy lmao

#

well thx

weak plinth Aug 12, 2019, 6:34 PM

you are free

#

#

decide and move on 😎

@jade glacier That graph is cool, home made?

jade glacier Aug 12, 2019, 7:46 PM

#

yeah, its a monitor of how long things have been on the buffer for each frame in the ring buffer @wild badge

#

The purple bars indicate loss/late - I was hitting it pretty hard with Clumsy induced packetloss to see how well determinism of physx could be restored

#

The whole thing has an Overwatch like buffer management thing going on, so clients change their sim rates based on the server telling each client how over/undersized its buffer is for that client

wild badge Aug 12, 2019, 9:13 PM

What do you use the render this?

#

I've been wanting to display some similar data, but wasn't sure what would be the best approach

Hi guys! Having a problem with my game server, hoping you can help.

My latest server build for some reason doesn't allow me to connect.

I get this error message:

No connection could be made because the target machine actively refused it.

Full error message below

||Client Recv: failed to connect to ip=108.61.199.110 port=7777 reason=System.Net.Sockets.SocketException (0x80004005): No connection could be made because the target machine actively refused it.

weak plinth Aug 14, 2019, 7:21 AM

#

compare the changes

formal marsh Aug 14, 2019, 7:58 AM

#

Well, that was actually not a bad idea. I've been backtracking what I've done and found the change at fault

That leads me to another question, because what caused the crash was a change in the network manager.
I made a script that inherits from : NetworkManager, and replaced the old network manager script in the inspector with this one.

#

here:

#

#

And I guess I must have done something that is not allowed when you make that change, although I don't know what that could be

stray scroll Aug 14, 2019, 8:37 AM

#

Hmm, if it's a built version you are running try close down unity. Or if you have multiple unity up that uses same port.

formal marsh Aug 14, 2019, 9:16 AM

#

I found the fix

In a custom network manager that derives from NetworkManager, if I do something in Awake(), I need to do

public override void Awake()
{
base.Awake();
//Whatever I want to do
}

What I had was just

void Awake()
{
//What I wanted to do
}

stray scroll Aug 14, 2019, 12:01 PM

Anyone been using the new Network System combined with Input System? Or in general, if you would lack a simulation frame behind on client, would you use the same input as last frame (e.g. delta on mouse), or reset it ? Or consider the client to have authority on the rotation and send the current rotation instead of delta mouse? (e.g. fps)

Anyone would have any idea why this isn't working correctly? At high frame rates it simply hacks at bits, but at lower (below 60) it won't rotate at all.

                for (uint tick = snapshotData.Tick + 1; tick != predictedTick + 1; ++tick)
                {
                    var playerCommandDataBuffer = chunkPlayerCommandDataBuffer[i];
                    PlayerCommandData commandData;
                    playerCommandDataBuffer.GetDataAtTick(tick, out commandData);
 
                    if (tick == predictedTick)
                    {
                        CharacterMovementUtilities.Rotate(ref rot, commandData.frameInput.playerRotationAxis.x);
                    }
                    else
                    {
                        rot.Value = commandData.frameInput.playerRotation;
                    }
                 
                    //.....
 
                }
 
 
                PlayerCommandData cmData;
                chunkPlayerCommandDataBuffer[i].GetDataAtTick(predictedTick, out cmData);
                cmData.frameInput.playerRotation = rot.Value;
                Debug.Log("Predict tick:" + predictedTick + " " + rot.Value);
                chunkPlayerCommandDataBuffer[i].AddCommandData(cmData);

#

I send rotation with my commands to the server. The idea above is to only calculate the rotation on the predicted tick.

stray scroll Aug 15, 2019, 10:49 AM

#

Think I solved half of my problem, where GetDataAtTick default sets the rotation to 0, 0, 0, 0 at the first ticks where there are no commands.

gray ether Aug 15, 2019, 4:40 PM

#

hi all, using UNet here. when i use NetworkIdentity.Instantiate it worked on the host (because this was done on start) but not on the client connecting afterwards, any idea how i can get this working? e.g. when i instantiate an object, it is shown on clients connecting afterwards

stray scroll Aug 15, 2019, 4:50 PM

#

Isn't that server only thing?

gray ether Aug 15, 2019, 4:50 PM

#

Maybe... not sure where to go from here

stray scroll Aug 15, 2019, 4:51 PM

#

usually I think you instanciate it and then use NetworkServer.Spawn(object)

gray ether Aug 15, 2019, 4:52 PM

#

hmm... thanks! i will try that now!

stray scroll Aug 15, 2019, 4:53 PM

#

But you need to do this on the master client I think. So you'd have to either check that a new client has connected, or send a command to it.

glacial totem Aug 15, 2019, 5:10 PM

#

Hey guys, in a physics based networked game, the client needs to be ahead of the server so that the by the time the input command packet reaches the server, the tick has not already passed.

However, I’m having trouble finding something that actually explains how to get the client ahead.

#

During the initial connect, the server sends the client its tick number so the client can start at the same tick, but latency obviously means that the client will be behind, so if the client is able to know it needs to speed up, how is that speed up achieved?

#

My client knows how far behind it is because i coded the sever to notify it when it is, just not sure what to actually do with that information. If the client is 5 ticks behind, do I just simulate physics for 5 ticks all at once with the last player input to catch it up?

jade glacier Aug 15, 2019, 5:50 PM

#

At a glance it seems like you might be thinking about things a bit backwards

#

You want client prediction I assume

#

what that usually means is you apply your inputs locally immediately, and you send those inputs to the server along with a tick number, and the server applies those input tick values to its simulation ticks

#

So basically you have the owner and the server both applying the same simulation to the player object

#

The server broadcasts the state results (transform values) along with the tick number... and the player compares its old results for that tick with what the server got.

glacial totem Aug 15, 2019, 5:52 PM

#

Correct

#

I have all of that already

jade glacier Aug 15, 2019, 5:52 PM

#

If they disagree, the server is considered right... and the client needs to resim

#

So if you have that... your player is already in the future

#

it sees the world around it as history (because of buffers and net latency)

glacial totem Aug 15, 2019, 5:53 PM

#

It's not tho, because by the time tick 100 reaches the server, the server is already on tick 105, for example

jade glacier Aug 15, 2019, 5:53 PM

#

you have to reconcile your tick numbers of course, since you have multiple timeframes

#

The server is reality though

#

What the player sees is a lie

#

The only exception is that you can make server checks favor the player... for like hitscan weapons

glacial totem Aug 15, 2019, 5:54 PM

#

So the client connects to the server when it's on tick 100, so the server says start at tick 100. But by the time the client receives that info, the server is already in the future from latency right?

jade glacier Aug 15, 2019, 5:54 PM

#

And the server will rewind the scene to its best recreation of what the player likely was seeing

#

I personally don't do that

#

Personally, I just let every client have its own tick

glacial totem Aug 15, 2019, 5:55 PM

#

Yeah this is a physics based sports game like RL

#

that will never work

jade glacier Aug 15, 2019, 5:55 PM

#

and I establish offset values

#

What will never work?

glacial totem Aug 15, 2019, 5:55 PM

#

server can't rewind

jade glacier Aug 15, 2019, 5:55 PM

#

Then the client has to deal with desyncs

glacial totem Aug 15, 2019, 5:56 PM

#

Right, so I'm dealing with that via prediction and rewinds on the client

jade glacier Aug 15, 2019, 5:56 PM

#

no server rewind just means that what the client sees when it fires may not be reality, unless you just allow client authority for hit claims

glacial totem Aug 15, 2019, 5:56 PM

#

But i guess the problem I have is that the server doesn't know when to process the buffered input because the ticks are already behind

#

all it can do is process the latest command at that point

jade glacier Aug 15, 2019, 5:57 PM

#

its just sequential being pulled from the buffer

#

I personally just have a dict<netid, offset>

#

So all incoming and outgoing frames can be converted to and from the local tick values

#

Trying to get them all on the same tick is pointless

#

because the player lives in the future on clients

#

so you have two timeframes going at all times

#

Most of the work is in sorting out how to convert things between the timeframes

glacial totem Aug 15, 2019, 5:58 PM

#

So the client needs to be ahead right? The client needs to be on tick 105, for example while the server is on tick 100, so that by the time the command for tick 105 reaches the server, the server hasn't already processed tick 105.

jade glacier Aug 15, 2019, 5:59 PM

#

Not so much needs to be ahead... it just SEES itself as ahead. You are moving instantly, knowing that the world you see around you is NOT the world the server will see around you when you make that move in its sim

glacial totem Aug 15, 2019, 5:59 PM

#

A physics simulation has to stay perfectly in sync, so maybe it's a different way of thinking than you're used to?

jade glacier Aug 15, 2019, 5:59 PM

#

Perfectly in sync is not possible without determinism

#

If you want full determinism, you have to extrapolate

#

so that the player is not in the future

#

But rather is always in the best guess of the present

#

extrapolation is notoriously WRONG though, so you have to resim constantly

glacial totem Aug 15, 2019, 6:00 PM

#

That is correct. but i mean the timing needs to stay in sync. What the client is applying to the physics simulation has to be what the server is applying at the same physics state.

#

So the physics state and simulation entirely needs to be ahead on the client

jade glacier Aug 15, 2019, 6:01 PM

#

That will just happen, as long as your server is consuming your input frames at the same rate as your client is producing them

#

The needs to be ahead part I am not getting, I think you are trying to control something you have no control over

#

The server keeps a small buffer of inputs, and pulls from it on the tick

#

How many frames of buffer and frames are moving on the network will vary, and you have some control over that

glacial totem Aug 15, 2019, 6:02 PM

#

the client also buffers inputs too

jade glacier Aug 15, 2019, 6:02 PM

#

client shouldn't buffer inputs, other than the hold time between Update and the next Fixed

#

that would just be producing input lag

#

Every fixed you should capture the input values, and you use those values for your local sim and to send to the server for its sim

#

Clients will buffer states however

#

the server sends out its resulting scene state to all

#

and you want to buffer that, so things are smooth

glacial totem Aug 15, 2019, 6:03 PM

#

The client isn't gonna be sending a packet per input tho....

jade glacier Aug 15, 2019, 6:03 PM

#

But those states are numbered as well

#

That isn't really buffering though

#

that is just batching

#

If you send every 3 ticks...

#

you are locally applying inputs for all 3 of those ticks

glacial totem Aug 15, 2019, 6:04 PM

#

ahhh terminology misunderstanding there sorry

jade glacier Aug 15, 2019, 6:04 PM

#

you just aren't sending them right away

#

Keep in mind though of course, that is going to increase your latency quite a bit

#

Because now you have a MIN buffer of that SendEveryX value

#

The server has to be at least that many ticks behind

#

What is your physics tick rate?

glacial totem Aug 15, 2019, 6:06 PM

#

But let's look at this situation:
Server sends the first state update to the client and says Object 1 is at this position at tick 10
A bunch of input happens and on tick 20 the client input effects the object
When the server gets that input command, it needs to know that it was for 10 frames in the future at tick 20

#

So the scenario you're describing leaves that matching purely up to timing

#

instead of selectively applying the input for the tick at the correct time?

jade glacier Aug 15, 2019, 6:07 PM

#

Actually more the other way around

#

the server doesn't care - it will maintain the smallest buffer you can get away with

#

and it will pull inputs from that buffer at a fixed rate

#

The results of its sim it sends out as a state

#

you will want to have a way to reconcile WHICH player tick that result corresponds to

#

I personally send out two tick values

#

the second one being the origins tick id

#

So that the player easily can just know which of its own ticks in the past this lines up with

#

So basically at the start of every outgoing server packet I have a [ServerTickID][OwnerTickId]

#

That way if the server had to do any buffer corrections, the client doesn't have to get crafty about detecting that

#

It just says "you sent me Tick X - I am giving you back Tick X results"

#

You can get away without the two values, and have it only send back the translated owner tickID, depending on your needs. I need the server tick ID because I use that for modulus stuff that tells me if I have forced keyframes and such

glacial totem Aug 15, 2019, 6:12 PM

#

So where does latency detection come into play on your end?

#

Like using the reported latency to move the client further or less into the future?

jade glacier Aug 15, 2019, 6:12 PM

#

That whole packet on the client side just goes on to a buffer... HOWEVER it does something different with the part of the packet that is for its owned objects... since its not going to actually apply those values - for those it goes back to its history and checks for a desync

#

No need for latency info, this is all tick based, not time based

glacial totem Aug 15, 2019, 6:13 PM

#

maybe that's the problem then?

jade glacier Aug 15, 2019, 6:13 PM

#

You are tick based I assume? You want to be.

glacial totem Aug 15, 2019, 6:13 PM

#

Overwatch and RL both do active predictions based on latency on the client's end

jade glacier Aug 15, 2019, 6:13 PM

#

There is no solution to the problem - the server and the owner will ALWAYS be in disagreement - but that doesn't mean desync

#

If you extrapolate a bit you can start to apply that stuff

#

Basically cheat the visuals

#

You are talking about the client extrapolating other objects I assume

#

rather than interpolating

glacial totem Aug 15, 2019, 6:15 PM

#

Yeah they don't cheat the visuals either. The client's entire simulation is like legit ahead of where it should be. Which is why with 300 ping in RL, as long as it's just you and the ball without any other players, there is 0 desync ever

#

Because client's entire simulation is identical, just in the future and no outside forces are changing that simulation

#

Maybe I just misunderstand the entire concepts tho...

#

This is all new to me.

jade glacier Aug 15, 2019, 6:16 PM

#

You are describing the impossible, the simulations can only be identical

#

Determinism tries to fake that

#

it extrapolates the world to get the time frames in sync, but that means its is constantly in a state of guessing

glacial totem Aug 15, 2019, 6:16 PM

#

what's impossible?

jade glacier Aug 15, 2019, 6:17 PM

#

it is impossible to have immediate client inputs locally and have identical simulations, unless you are extrapolating

#

but then it is cheating

#

Quantum does it by CONSTANTLY resimulating

glacial totem Aug 15, 2019, 6:17 PM

#

I don't understand why that would be impossible?

#

If nothing else is acting on the simulation

jade glacier Aug 15, 2019, 6:18 PM

#

Because there is no way to know what other players are doing 300ms in the future

glacial totem Aug 15, 2019, 6:18 PM

#

I said just you and the ball

#

without any other players

jade glacier Aug 15, 2019, 6:18 PM

#

yeah, but for that model to work - you have to sort out what happens when you are desynced

#

You and the ball isn't the game - you will see other players

glacial totem Aug 15, 2019, 6:18 PM

#

once you have any other players it's terrible because your client is so far in the future, that any state corrections are drastic

#

but that's expected

jade glacier Aug 15, 2019, 6:19 PM

#

yeah, because you are extrapolating

#

Typically if you are using player inputs, extrapolation works reasonably well

glacial totem Aug 15, 2019, 6:19 PM

#

Okay extrapolation is what I need then

jade glacier Aug 15, 2019, 6:19 PM

#

because players tend to hold buttons down and generally do predictable inputs

glacial totem Aug 15, 2019, 6:19 PM

#

it has to be what they do

#

And whatever they do is the best in the world. It's the most successful networked physics game there is.

jade glacier Aug 15, 2019, 6:20 PM

#

Just be aware that with extrapolation, you have to constantly resim - because it means what you are showing the player is a guess

glacial totem Aug 15, 2019, 6:20 PM

#

Correct

#

So maybe we need to restart, because i understand all of that

jade glacier Aug 15, 2019, 6:20 PM

#

Then I don't see the question, because you understand the problem

glacial totem Aug 15, 2019, 6:20 PM

#

My state corrections reset the state and then re-extrapolate forward back to the frame the client was on with the same inputs from the past

#

The problem is that the original state isn't extrapolated yet

#

only the corrections

#

So I'm wondering how to go about extrapolation when the client is behind

#

is it as simple as just taking the current state and simulating physics for as many ticks as I want to get ahead?

jade glacier Aug 15, 2019, 6:22 PM

#

You should know by the tick delta if you have the server giving you back results in your local tick value

#

Player send Tick 10 ... Server buffers Tick 10... Server applies players tick 10... server adds "10" to the header of the state it sends back to the player

glacial totem Aug 15, 2019, 6:23 PM

#

yeah so maybe my original question didn't make that clear. I have everything ready, I already know how far behind the client is where it should be, for example 5 ticks behind, I'm just not sure how to extrapolate those 5 ticks ahead to correct it

jade glacier Aug 15, 2019, 6:23 PM

#

Player is now on tick 16 when it gets the servers results for state 10

glacial totem Aug 15, 2019, 6:23 PM

#

I think it's as simple as I was assuming, but i just wanted confirmation from someone more experienced

jade glacier Aug 15, 2019, 6:23 PM

#

You seem to get the problem, the answer will vary a bit depending on your other mechanisms

#

like how you are number, offsetting, and predicting

glacial totem Aug 15, 2019, 6:24 PM

#

Player says what results did my siluation produce back in the history for state 10
Player says it looks good so continue, or it says wrong prediction and performs a rewind correction

jade glacier Aug 15, 2019, 6:24 PM

#

they just all have to be on the same page

#

The issue you will have is your player is PREDICTING all of the other clients

glacial totem Aug 15, 2019, 6:24 PM

#

right exactly

#

I guess the probkem right nowe is that it's not actually predicting others

#

because the simulation isn't ahead

jade glacier Aug 15, 2019, 6:25 PM

#

So to do that well you want it to be simulating all of them probably, not just be extrapolating states

#

states extrapolate poorly, inputs extrapolate well

glacial totem Aug 15, 2019, 6:25 PM

#

It's behind the server's simulation because of latency

#

Right, so it sounds like i need to include each player's current input in the state updates

#

So that i can use those inputs to keep extrapolating with them ass if they don't change

jade glacier Aug 15, 2019, 6:25 PM

#

As long as you are still calling the server god, yeah - you basically have to be extrapolating out to what frame your player currently is creating

glacial totem Aug 15, 2019, 6:26 PM

#

or what RL does i think is that it decays the inputs?

jade glacier Aug 15, 2019, 6:26 PM

#

Depends on the input, but that is very game specific

glacial totem Aug 15, 2019, 6:26 PM

#

okay

jade glacier Aug 15, 2019, 6:26 PM

#

You just have to play with how to extrapolate specific to your game and see what breaks the least

#

or breaks in the least offensive way

glacial totem Aug 15, 2019, 6:26 PM

#

So basically i need to advanced the physics simulation ahead to get the client ahead, but i can't do that without also being aware of each player's last inputs

#

Otherwise the player's velocity will slow down from gravity or other physics instead of continuing on

#

as if they were keeping the same input

jade glacier Aug 15, 2019, 6:27 PM

#

I wouldn't so much say advance the physics... so much as extrapolate a guess for the inputs

#

you are nearly full deterministic here

#

If you want to extrapolate with inputs, you would pass all player input structs to everyone

#

and your local sim would apply all players guessed inputs

#

And whenever it guesses wrong, it has to go back for a resim

glacial totem Aug 15, 2019, 6:28 PM

#

When i exyrapolate, i want it to be the entire simulation extrapolated, so that if there's no corrections, all the visuals were untouched and the server "visuals" were the same

#

okay extrapolate with inputs sounds like what I want

#

And I'm pretty sure RL does that too

jade glacier Aug 15, 2019, 6:29 PM

#

Keep in mind that you already have two worlds

#

FixedTime = simulation inputs and states

#

Update = cosmetics

glacial totem Aug 15, 2019, 6:29 PM

#

They just decay the inputs over time if a new state doesn't come in to give updated input values

jade glacier Aug 15, 2019, 6:29 PM

#

Resim goes back and reworks the history of Fixed/States

glacial totem Aug 15, 2019, 6:29 PM

#

like if the player was steering left, over time they will center out

jade glacier Aug 15, 2019, 6:30 PM

#

Your Update loop can be a lot more mushy

glacial totem Aug 15, 2019, 6:30 PM

#

Yeah all of this is happening in Fixed Time

jade glacier Aug 15, 2019, 6:30 PM

#

since its basically lerping things from where they are to where they should be

#

The main thing most people have trouble with there is they have one sim going - the visible one

glacial totem Aug 15, 2019, 6:31 PM

#

So going back to the original convo, instead of keeping different tick counters, I'm forcing the client to adjust the tick number to match the servers instead as if the server was ahead where the client is

jade glacier Aug 15, 2019, 6:31 PM

#

rather than the sim being a totally virtual world - separate from the rendered world

#

and I would add some extra tick info if need to be to make it easy to sort out which tick lines up with which on the client vs the server

#

For my stuff I ended up with two tick values

#

you may need something different

glacial totem Aug 15, 2019, 6:32 PM

#

i haven't lerped anything yet but for state corrections am I correct that I should take the original position and the updated position after the simulation has been rewound and replayed and lerp that?

#

Like i don't need to lerp anything in between that right? Just the original value and the corrected value once the rewinding is done?

jade glacier Aug 15, 2019, 6:33 PM

#

That is actually totally up to you - how you cheat the corrections is subjective as hell

#

the main thing is to keep the cosmetic world separate

glacial totem Aug 15, 2019, 6:33 PM

#

okay makes sense. Some games might not lerp at all

jade glacier Aug 15, 2019, 6:33 PM

#

don't let it affect your simulation world

glacial totem Aug 15, 2019, 6:33 PM

#

yeah I'm not. I'm talking about this entire discussion as if it's all numbers without any graphics tbh

#

i think I'm getting it now and I think my code changes this morning accounted for what I needed to fix. Just wanted a second opinion

jade glacier Aug 15, 2019, 6:34 PM

#

then sounds like you mainly just need to sort out how to get the various tick timeframes to reconcile and agree

#

Its a good idea to avoid the cosmetic stuff like you are

glacial totem Aug 15, 2019, 6:34 PM

#

I'll keep playing with it, but it's a lot different from the server just applying whatever input it can when it gets it lol

jade glacier Aug 15, 2019, 6:35 PM

#

making it pretty bloats and complicates things too early

#

its good to see it raw in this step... ugly corrections and all

#

makes it easy to tell how your code is working

glacial totem Aug 15, 2019, 6:35 PM

#

It probably helped that I watched like 8 hours of GDC physics networking conferences from Rocket League and Overwatch before getting into this....

jade glacier Aug 15, 2019, 6:35 PM

#

yup, very important

#

but also hard to get your head around until you make a couple failed attempts

glacial totem Aug 15, 2019, 6:36 PM

#

Basically my game is another physics based networked sports game, so I want to do whatever RL did since they were the most successful

#

It can be argued that no game had it figured out before they did probably lol

#

with some of their techniques

jade glacier Aug 15, 2019, 6:36 PM

#

I don't fully know RLs code choices - but I have to assume they extrapolate all kinds of stuff

#

Overwatch is mostly traditional, but they take advantage of determinism where they can find it to extrapolate

glacial totem Aug 15, 2019, 6:37 PM

#

They apparently buffer the inputs on the server so they can apply them at the correct time,., but they actively do stuff to let the buffer shrink or grow dynamically to keep it at a sweet spot

jade glacier Aug 15, 2019, 6:37 PM

#

you have to buffer the inputs for sure

glacial totem Aug 15, 2019, 6:37 PM

#

If the buffer is low, they repeat inputs and process them again, if the buffer is full, they skip inputs

#

I still don't fully get it

jade glacier Aug 15, 2019, 6:38 PM

#

its a tick based sim, you can't consume inputs any other way

#

That should be rare

#

for OW it doesn't toss inputs as far as I know

glacial totem Aug 15, 2019, 6:38 PM

#

They handle it on the server, and Overwatch does the opposite.

jade glacier Aug 15, 2019, 6:38 PM

#

ooooh

#

you mean RL

glacial totem Aug 15, 2019, 6:39 PM

#

correct

#

Overwatch does the same shit, but makes the client do it

jade glacier Aug 15, 2019, 6:39 PM

#

OW doesn't toss them,it just asks the clients to change their sim speed to try and get its buffers back to a better size

glacial totem Aug 15, 2019, 6:39 PM

#

Instead of the server skipping or duplicating inputs, the sevrer tells the client to actually run slightly slower or faster to keep the buffer adjusted

jade glacier Aug 15, 2019, 6:39 PM

#

tossing and repeating an input = instant desync

glacial totem Aug 15, 2019, 6:39 PM

#

a 120hz simulation will dynamically change to 119hz or 121hz, etc.

#

which is just wild

jade glacier Aug 15, 2019, 6:40 PM

#

its actually not too hard

#

My test lib does that

#

I have the server send a byte that indicates how happy it is with its buffer size

#

So the client adjust its sim rate. Only works with Unity 2018.3 or newer though

glacial totem Aug 15, 2019, 6:41 PM

#

📎 unknown.png

jade glacier Aug 15, 2019, 6:41 PM

#

yeah, I would not have done that - but their game

glacial totem Aug 15, 2019, 6:41 PM

#

Overwatch uses an Upstream throttle, which RL already implemented and is changing to

#

you can actually switch via client settings

#

which is interesting

jade glacier Aug 15, 2019, 6:42 PM

#

none of it is super hard, because the desync is handled elsewhere

glacial totem Aug 15, 2019, 6:42 PM

#

Yeah even if they made the wrong choice, it's still probably the most enjoyable and least error prone physics based game out there

jade glacier Aug 15, 2019, 6:42 PM

#

I just would rather avoid creating desyncs

glacial totem Aug 15, 2019, 6:42 PM

#

It's no doubt a large reason for their success

jade glacier Aug 15, 2019, 6:42 PM

#

of course, there is no one right answer

#

They are also using cars, so they aren't as twitchy

glacial totem Aug 15, 2019, 6:43 PM

#

yeah exactly

#

much slower reactions

jade glacier Aug 15, 2019, 6:43 PM

#

so a lost input and correction probably aren't that noticable

glacial totem Aug 15, 2019, 6:43 PM

#

120hz physics simulation with 60 tick servers too

jade glacier Aug 15, 2019, 6:43 PM

#

Forcing a resim is a bit of work, but it does let them stick to a fixed tick rate

glacial totem Aug 15, 2019, 6:43 PM

#

So that also helps it be less noticable

#

add in interpolation on the corrections and it's pretty damn good i guess

jade glacier Aug 15, 2019, 6:44 PM

#

its all going to get glossed over with the cosmetic layer yeah

glacial totem Aug 15, 2019, 6:44 PM

#

Really appreciate the time you took to explain some stuff tho. I think it helped me understand a lot.

jade glacier Aug 15, 2019, 6:44 PM

#

np, keep everyone posted on your progress

glacial totem Aug 15, 2019, 6:44 PM

#

i thought i was way further off than i was i guess

jade glacier Aug 15, 2019, 6:45 PM

#

I'm still always learning this stuff as I go

glacial totem Aug 15, 2019, 6:45 PM

#

yeah it's interesting stuff and always love a new challenge.

#

this game is gonna be a hockey-based physics game

#

it's early but i've been focusing on the physics networking because it can certainly make or break the game

#

Wanted to know I was capable of figuring it out and making it an enjoyable experience before I went any further

jade glacier Aug 15, 2019, 6:47 PM

#

definitely the right approach

halcyon vessel Aug 16, 2019, 2:43 PM

#

i'm struggling to play sounds for every player in my game using photon. Once the projectile meets a player collider, i want to play a "hit" sound, but calling

    private void playerHitSound(Vector3 pos)
    {
        AudioSource.PlayClipAtPoint(playerSound, pos);
    }```
it does only play the sound for the player who shot the projectile
(i precise that this function is in my player script, and is called from the projectile script)

stray scroll Aug 16, 2019, 6:11 PM

#

@halcyon vessel And you do something like photonView.RPC("playerHitSound", RpcTarget.All, pos) ?

halcyon vessel Aug 16, 2019, 6:58 PM

#

yes exactly, in the projectile script

#

@stray scroll

stray scroll Aug 16, 2019, 7:06 PM

#

If you target all I can't say what is wrong. Haven't used Photon in a while. I would write a debug line as well, check if it's both ways. Is the player removed as well from the collider, making an invalid target for RPC? Is there any error/warning messages?

halcyon vessel Aug 16, 2019, 7:08 PM

#

I used a debug to verify if the function is called, and it is, no errors or warning. It looks to be the normal behavior of the function

carmine dragon Aug 18, 2019, 3:04 PM

Hey guys, sorry for being probably the 100th guy asking this this week but.. is the FPS sample really the way to go for making a multiplayer game with Unity 2019.2? I've yet to find some solid documentation about the networking part and it's weird to use a library from copypasting a couple of scripts from another project. Normally in software development you give at least one solid choice.. you deprecate libraries when others are ready to replace the need. It's not like MonoBehaviours are deprecated because DOTS has arrived in preview right?

halcyon vessel Aug 18, 2019, 3:30 PM

#

what are you using, photon or unity network ?

stray scroll Aug 18, 2019, 3:45 PM

#

@carmine dragon https://blogs.unity3d.com/2019/06/13/navigating-unitys-multiplayer-netcode-transition/

#

If you're not into ECS stuff, you can also go with Photon, mirror (like old UNET) https://assetstore.unity.com/packages/tools/network/mirror-129321, or some other third party like DarkRift2 (which you might need to write a bit more code for)

Yep, DOTS Multiplayer is not easy atm. A few samples and almost no documentation. Though i got it up and running with my project and it works so far. But i hope there is a preview version available soon. Was promised for Q3.

carmine dragon Aug 18, 2019, 6:51 PM

Is it based on the same codebase as the FPS Sample? Would be nice to see them using it as a package as well.

Hey guys, new here, bit of a discord nut so i don't know why i wasn't here already lol. I have an issue though deploying a linux server build to a unbuntu server using putty and ssh. When i run my server with the -nographics parameter it starts loading up then aborts due to 4 unknown errors that report that the Internal-ErrorShader.shader could not be loaded. Anyone got any clue on this and can I copy a snippet of the errors in question here?

When you host a game on a service like idk Amazon, what does this means ? do you have a virtual machine on a distant server where you run a instance of your game in server mode or is it something more like using the server as a relay for better connection ?

weak plinth Aug 19, 2019, 1:29 PM

#

i have a vps where i host the server

#

which right now is not a unity made server

#

but it is c# (.net core)

solar garden Aug 19, 2019, 1:32 PM

#

but it is a instance of you game righ t?

weak plinth Aug 19, 2019, 1:32 PM

#

what?

solar garden Aug 19, 2019, 1:33 PM

#

you were answering me ?

weak plinth Aug 19, 2019, 1:33 PM

#

i run the server on my linux vps

#

what do you mesn

#

mean

solar garden Aug 19, 2019, 1:33 PM

#

what is a server ?

weak plinth Aug 19, 2019, 1:33 PM

#

google it

solar garden Aug 19, 2019, 1:34 PM

#

is it a instance of the game ?

weak plinth Aug 19, 2019, 1:35 PM

#

depends how u define it 1) a remote machine which u can run stuff on 2) a program which runs on a network to which clients connect

solar garden Aug 19, 2019, 1:35 PM

#

i mean for unity 😫

weak plinth Aug 19, 2019, 1:35 PM

#

i told you my server is written in .net core

#

a crossplatform version of c#

#

and no its not made with unity

solar garden Aug 19, 2019, 1:36 PM

#

for csgo you have a application that is using the same game files as the original game to run a server but it still acts as a game instance

weak plinth Aug 19, 2019, 1:37 PM

#

well ofc it uses same game files for calculating stuff

solar garden Aug 19, 2019, 1:38 PM

#

but its a application on a remote machine right ?

weak plinth Aug 19, 2019, 1:39 PM

#

not always as you can run a server and client on the same machine

solar garden Aug 19, 2019, 1:39 PM

#

yeah but the remote server is made for better networking perfomance

#

but its no different

weak plinth Aug 19, 2019, 1:40 PM

#

i really dont get what u want

solar garden Aug 19, 2019, 1:40 PM

#

when using a service to host games

#

the service is a server (a computer) where you launch a instance of your game set in hosting mode right ?

#

you know like with a desktop and all

#

that you can access remotely like with teamviewer

stray scroll Aug 19, 2019, 1:42 PM

#

depends on what your service is?...

#

I mean a basic thing is that you go to something like digitalocean, buy a virtual machine, upload and run your application(server).

solar garden Aug 19, 2019, 1:45 PM

#

thats what i am wondering when peoples make games in unity on the internet they talk about Photon hosting or distant servers, now distant servers are just virtual machines where i gues you would launch a instance of your game in hosting mode simple enought, but for things like photon hosting they dont have your game so how do they host things for you ??

weak plinth Aug 19, 2019, 1:46 PM

#

go to photon support ?

solar garden Aug 19, 2019, 1:47 PM

#

its not unique to photon unity was also doing something similar

#

you could choose players number in a game and you were all set

weak plinth Aug 19, 2019, 1:48 PM

#

🤷

#

again it depends on what u wanna do

#

if u just want info about some asset go ask their devs

I haven't used photon too much, but I think their default thing is that they have relay servers and room listing. But make a google search on it 😛

solar garden Aug 19, 2019, 1:50 PM

#

ohh so they are relay servers

#

they are not hosting your game only forwarding your connection

#

but you host your game yourself on your machine

stray scroll Aug 19, 2019, 1:55 PM

https://doc.photonengine.com/en-us/realtime/current/getting-started/onpremises-or-saas

Well, the basic idea is that you have one master client, if he/she leaves another one will be assigned.

stray scroll Aug 19, 2019, 1:58 PM

#

Check the link I sent, there is a server option as well.

solar garden Aug 19, 2019, 2:00 PM

#

But the actuall hosting is from any of the clients thats what i didn't understood in either case on a dedicated server or local hosting like UNET or Photon, one instance of the game is launched to actually host the game

#

Photon just redirect the connection but it is peer to peer

stray scroll Aug 19, 2019, 2:24 PM

#

I don't know how their server solution works, you have to check that out yourself.

Hello, iam using photon 2. I can get the editor and a standalone to connect to the same room. But when i try with a friend we connect to different. I tried with 2 friends and they get into the same room while i get into another. Geograpically this shouldnt be a issue. Any tips or thoughts?

stray scroll Aug 19, 2019, 2:39 PM

#

You're using the same room name?

maiden sundial Aug 19, 2019, 2:40 PM

Well i have "JoinRandomRoom" but as i understand it, it should fill the room before going to another room?

#

My standalone and editor always join the same room

@maiden sundial in the start function of your code, if you use photon, you only activate the camera if photonView.isMine is true

actually you will need photonview.ismine a lot, for example if you shoot, you want only your own player to shoot and not others. In fact i put almost all my code into that if(photonview.ismine)
