Why is this happening?

jade glacier Jul 12, 2020, 1:16 PM

#

Without seeing, I would suspect a bug in your code somewhere.

#

Does that happen for you with any of the tutorial scenes?

#

@austere kiln

#

Also would be good to turn up your logging settings for pun2, to see if you get any kind of messages as to why.

austere kiln Jul 12, 2020, 1:21 PM

#

I've posted the scripts, will they be enough for checking? Cause I'm really stuck and have no idea what's causing it

#

@jade glacier

jade glacier Jul 12, 2020, 1:26 PM

#

I can only see what I see here (busy working so I can't really dig into your project) - you are going to have to do the usual debugging involved in these things.

Do the demo scenes exhibit this behavior?

#

you are doing some not-beginner stuff there with scene changes and such, so I would add that code very slowly to a working one scene project and see what breaks it.

austere kiln Jul 12, 2020, 1:44 PM

#

I've updated the scripts abit and I'm about to post the same question in Photon Engine Server

#

Let's continue there

jade glacier Jul 12, 2020, 6:14 PM

#

Best to not cross post, I would pick a channel and stick to it there. Many of the networking channels are the same people and it generally is frowned on cross posting like that, and will likely get you ignored.

vapid leaf Jul 12, 2020, 10:15 PM

#

so i dont know if this is too advanced for multiplayer for me at this moment but basically im making a game where you can switch in between characters with different abilities (Kinda like the lego games) and i dont want more than one player to be the same character. I tried using mirror and it didnt really work the way i did it. Does anyone know any good programs and the gist or any tutorials that know how to do that?

vapid leaf Jul 13, 2020, 12:29 AM

#

One program i was thinking about using was photon bolt for peer to peer co op

spring crane Jul 13, 2020, 3:01 AM

#

I don't think switching the networking solution is going to help here

gleaming prawn Jul 13, 2020, 7:50 AM

#

Agree with the above

#

Either of these API/SDKs would work... You need to take your time, understand a bit better what you are doing, etc.

#

(As a photon engineer, I could be pushing for Bolt) There's nothing particularly wrong with Mirror for what you are trying to do.

hard badge Jul 13, 2020, 1:50 PM

#

hi guys

#

just wondering

#

what is the best networking solution for a physics based game?

#

that uses active ragdolls that will be interacting with one another alot

jade glacier Jul 13, 2020, 2:10 PM

#

Quantum really will be your only option. Since what you are describing really doesn't play well with state interpolation, which is what you will be starting with using Pun2, Mirror, or Bolt. @hard badge

#

If this is your first networking rodeo, I would NOT start with that type of game.

#

Unless you have funding and can get into Photon Quantum.

hard badge Jul 13, 2020, 2:17 PM

#

alright thank you

vapid leaf Jul 13, 2020, 2:34 PM

#

I was using mirror and the thing is that the buttons were not able to be pressed. I already have some of my game that was done offline and I have a script for my camera with the 2 lines about cursor.lockstate and cursor is visible which is why it probably doesnt work. All of my scripts written derive from monobehavior and im worried im gonna have to rewrite all my scripts to fit with the server

Any idea on how to achieve peer 2 peer multiplayer hosting? I’m familiar with UNET and Photon, but then I’d need to upgrade photon for more players.

whole granite Jul 13, 2020, 5:36 PM

#

Hi guys. Does the Unity's Transport API has some sort of reliable message queue/buffer?
Basically you cannot send more than 32 reliable messages through the pipeline, as it will end you with an error and the message to be not guaranteed to be delivered.

Tho, simple buffering of these messages for later sending (i.e. wait for the queue to get some free space), would probably make it a lot more reliable.

cedar cloak Jul 14, 2020, 9:56 AM

#

can somebody help me figure out how make a pickup script?

#

I'm trying to do an healthpack and I want that when the pickup enter in collision with a player, THAT player execute a "GainHealth" function

jade glacier Jul 14, 2020, 12:05 PM

#

Be sure to indicate the net library, since answers will vary based on the authority model @cedar cloak

cedar cloak Jul 14, 2020, 12:06 PM

#

i kinda did it right but photon "crashes"

jade glacier Jul 14, 2020, 12:06 PM

#

not sure what crashes in quotes means

cedar cloak Jul 14, 2020, 12:06 PM

#

Cannot send op: 253 Not connected. PeerState: Disconnected
UnityEngine.Debug:LogError(Object)

#

this happens few seconds after I interact with the pickup

jade glacier Jul 14, 2020, 12:08 PM

#

Sounds like maybe something in your code caused a flood of data that forced a kick maybe? Do yo have a loop that this creates where it calls the same RPC over and over?

#

I would turn up the pun logging settings to get as much info from the networking layer as possible

cedar cloak Jul 14, 2020, 12:10 PM

#

 private void OnTriggerEnter (Collider other)
    {
        if(other.attachedRigidbody == null)
        {
            return;
        }

        if (other.attachedRigidbody.gameObject.tag == "Player")
        {
            other.attachedRigidbody.GetComponent<InputController>().UnlockWeapon();

            photonView.RPC("Disable", RpcTarget.All);
        }
    }

#

this is the script, it's pretty basic

gleaming prawn Jul 14, 2020, 12:12 PM

#

I assume you are connected

cedar cloak Jul 14, 2020, 12:15 PM

#

I am

jade glacier Jul 14, 2020, 12:24 PM

#

And disable has no arguments?

#

Might want to paste your entire script into hatebin.com

true gate Jul 14, 2020, 3:12 PM

#

am in dire need for a networking expert to look at my game code and consider how much it gonna cost to add multiplayer function

gleaming prawn Jul 14, 2020, 3:18 PM

#

Basic answer:

multiplayer is not a function. You create your game from day 1 as multiplayer online
otherwise, very likely it will NOT work, or will be just BAD

#

You may find "experts" to fake something for you though...:)

#

Good developers will pretty much say the same I said (can be done, re-creating the game considering multiplayer this time)

true gate Jul 14, 2020, 3:21 PM

#

where can i find such developers to hire ?

gleaming prawn Jul 14, 2020, 3:33 PM

#

There a few here... Most already have stable jobs, I assume

#

It's like any other profession, if you have a good position available, that pays well, you'll get what you pay for.

#

Here we mostly discuss technical aspects between developers... If you have a clear job description (I already know it's indeed related to Networking/Multiplayer), post the link here... Should be fine.

i have 40mb mobile game btw

vapid leaf Jul 14, 2020, 4:19 PM

#

so i have this idea where you set the player prefab as an empty game object on a menu like screen where you select an actual character but if the movement scrpts are already active from another player you cant select them and then the camera transitions over to the character you selected. the only thing im worried about is idk how im gonna make it so that it doesnt interfere with cutscenes and stuff like that. does anyone else forsee any probs with this?

#

using mirror btw

gleaming prawn Jul 14, 2020, 4:30 PM

#

What do you mean by 40mb @true gate ?

#

40 Megabytes, Millions of Downloads?

true gate Jul 14, 2020, 4:31 PM

#

40 Megabytes

#

i need someone to look at my project scripts and figure how much it will take to add multiplayer to iOS and andriod

#

i will pay by the hour

gleaming prawn Jul 14, 2020, 4:44 PM

#

40MB have absolutely no meaning here... Have no idea why you said this...:)

#

It just says you have textures/models that bake as a 40MB build... Unrelated to whatever networking would be...

Hi all. This is for UnityWebRequest

How can i fetch content including what's in the scroll downs? Like facebook wall

gleaming prawn Jul 14, 2020, 6:36 PM

#

??? Are you experienced with web development?

#

A scroll is normally done with multiple dynamic requests as scrolling is done

#

You never fetch the whole at once...

#

It would not be different at all with unity... Do several paged requests resulting in JSON data (or anything else)...

vapid leaf Jul 14, 2020, 8:07 PM

Hello I have a problem with Photon Networking

#

This is my scritp that I attached to the player networking prefab

#

https://hastebin.com/unamihudez.cpp

#

look at line 21

#

It's supposed to display players nickname above the prefab

Anyone know about Socket.SendTo and memory allocation?
Every once in a while i see 22 allocations happen in my sending thread and the profiler claims it was done by Socket.SendTo. Is this normal?

weak plinth Jul 15, 2020, 11:46 AM

#

what would be the best way to create randomly spawning items? would it need its own photonview to sync its position?

jade glacier Jul 15, 2020, 11:58 AM

#

Not necessarily the best, but that would be the easiest.

jade glacier Jul 15, 2020, 2:29 PM

#

Which engine?

#

Unet is pretty much dead, so I would first consider switching to Mirror, and joining their forum.

#

They might have some kind of master server option, which you will need if you want a master list of active games.

#

Mirror Discord is the place to ask.

gleaming prawn Jul 15, 2020, 3:09 PM

#

You are talking about orchestrating server creation/spinning up (in case of dedicated servers)

#

This is normally sold as service by providers like amazon Gamelift or Unity's Multiplay...

#

If you are talking about creating a server with your local computer, then check if mirror offers a relay + punch service somehow (I think they do), so players can host servers in their own PCs

#

In either case it's not "a button", but rather part of your full solution (several services + code to coordinate this)

jaunty timber Jul 15, 2020, 10:23 PM

#

Does mirror work just like Unet?

vapid leaf Jul 15, 2020, 11:31 PM

#

So i was able to get the multiplayer to sync up and now your able to join servers for MIRROR but now i have the problem that the player can still switch to another character. The reason why this is is because i have an if statement that states if the movement script is enabled you cant switch to that character but for some reason on of the players games will say that the script is on and the other will says its off meaning that 2 players can play as one player and essentially possess the other player. Does anyone have a way so that if the script is off for one players game its off in all the other players and vice versa?

#

i want players to be able to switch between different playable classes like the lego games but for some reason you can have 2 players as one character which creates development console errors that say "null reference: object reference not set to an instance of an object" or something like that

Hey everyone, I'm using a unity implementation of SimpleJSON.
I'm trying to construct an array of two values called Parameters, but it loses the Key value inside the array, any idea what I'm doing wrong?

JSONObject jsonobj = new JSONObject();
        jsonobj.Add("name", inputCompanyNameField.text);
        jsonobj.Add("type", inputCompanyTypeField.text);
        jsonobj.Add("abreviation", inputCompanyAbreviationField.text);
        jsonobj.Add("location", inputCompanyAbreviationField.text);
        JSONArray parameters = new JSONArray();
        parameters.Add("product", "myvariable");
        jsonobj.Add("parameters", parameters);
        var payload = jsonobj.ToString();```

Returns: ```
{"name":"name","type":"Type","abreviation":"abreviation","location":"abreviation","parameters":["myvariable"]}```

**parameters:[] the key of the array is missing and only showing the value.**

Hello,

I'm trying to get GRPC to work on Unity on HoloLens2.

Current status:

Manually compiled a windows arm64 version of grpc_csharp_ext.dll (it came out in version 1.29.1). The reason for manually compiling: the grpc binaries do not include a windows arm64 version of grpc_csharp_ext.dll.
Used this version of unity grpc package: https://packages.grpc.io/archive/2019/10/8853754e8caa0b2ffb3ab0e25514f3f7612ebf7a-d6090f79-7b70-429d-a477-9df736e4941a/index.xml
- this is listed as 2.25.0, which I'm assuming refers to grpc 1.25.0
Build works in unity, and in the il2cpp project. The current exception on the HoloLens2 is attached.

Trying to resolve this, I have two possible directions:

Try to make the code find the dll (which is in the same dir as the .exe file),
Fix the version mismatch between grpc_csharp_ext.dll and the grpc package.
- note: tried using the a more advanced unity package (2.29.0), and it seems to be not working in unity (even before trying to add HoloLens2 into the mix). I did manage to get 1.25.0 working in unity (as well as in HoloLens1)

Any help would be much appreciated.

are PunRPC methods called globally or do I need to specify the script where it is?

fresh bone Jul 16, 2020, 6:25 PM

#

globally iirc

cedar cloak Jul 16, 2020, 6:25 PM

#

so i dont need static?

spring crane Jul 16, 2020, 7:01 PM

#

@cedar cloak It's done relative to the PhotonView you are targeting.

cedar cloak Jul 16, 2020, 7:01 PM

#

ok I have an issue so ill ask specifically

#

in a multiplayer match I need to clear objects that players drops by dying during the preparation match at the start of the "real" match

#

should I send a PunRPC method to all that basically destroy all these objects?

spring crane Jul 16, 2020, 7:04 PM

#

Drops should probably be scene objects, which can just be destroyed by the masterclient

cedar cloak Jul 16, 2020, 7:04 PM

#

[PunRPC]
    public void ClearDrops()
    {
        GameObject dropGroup = GameObject.Find("Circle/Map/Drops");

        foreach (Transform child in dropGroup.transform)
        {
            GameObject.Destroy(child.gameObject);  
        }

        Debug.Log("Drops Clear");
    }

#

this is my actual script

spring crane Jul 16, 2020, 7:05 PM

#

Ah they don't have photonviews?

cedar cloak Jul 16, 2020, 7:05 PM

#

they have

#

so should I just send that to the master or change aproach?

spring crane Jul 16, 2020, 7:05 PM

#

Then you should probably use the destroy method in Photon, which should be synced automatically

#

You would do something like that when the objects don't have photonviews

cedar cloak Jul 16, 2020, 7:06 PM

#

photonView.RPC("ClearDrops", RpcTarget.MasterClient);

#

so something like this?

spring crane Jul 16, 2020, 7:07 PM

#

Yea that should do

cedar cloak Jul 16, 2020, 7:09 PM

#

ok it solved it

#

nvm is got fixed only on master side

#

maybe it isnt owned by the scene

#

it is, heck

spring crane Jul 16, 2020, 9:48 PM

#

@cedar cloak Again, are you using the destroy method in PhotonNetwork?

cedar cloak Jul 16, 2020, 9:48 PM

#

yes

#

is it wrong?

spring crane Jul 16, 2020, 9:48 PM

#

No

#

How are you spawning them?

#

Spawn method in PhotonNetwork?

cedar cloak Jul 16, 2020, 9:50 PM

#

with a normal instantiate

spring crane Jul 16, 2020, 9:50 PM

#

Try the Photon equivalent

#

Don't remember exactly what it is called

cedar cloak Jul 16, 2020, 9:52 PM

#

oh its PhotonNetwork.Instantiate

#

i dont even knew that existed

#

does it instantiate that obj on all connected machines?

spring crane Jul 16, 2020, 10:00 PM

#

Yea. That should integrate a bit better with Photon than plain Instantiate.

jade glacier Jul 16, 2020, 10:02 PM

#

Yeah, that is the expected way to spawn things with Photon. You have been trying to manage that process yourself?

cedar cloak Jul 16, 2020, 10:10 PM

#

Acutally for now I just stopped developing for the day, its 00:10 here and I wasted all day trying to fix that

#

I know, that happens quite often, I'm just chilling out for now and waiting tomorrow for doing it

jade glacier Jul 16, 2020, 10:13 PM

#

Be sure to do the tutorials before trying to get too far. Guessing like you are doing is going to burn a LOT of time.

cedar cloak Jul 16, 2020, 10:24 PM

#

agree

#

i actually started with a long tutorial series but that got interrupted and I got the curiosity to try new things by myself

#

turns out multiplayer is 10 times more complicated than i expected

#

even because there's no much community around that and so there are few people that can help with these specific probles

jade glacier Jul 16, 2020, 10:26 PM

#

What’s the limit when it comes to photonviews? How many before it lags the game

vivid owl Jul 17, 2020, 4:01 AM

#

how would I handle matchmaking?

cedar cloak Jul 17, 2020, 6:50 AM

#

How can I setup a skin (material) systyem?

#

the problem is that iirc it's messy to change prefab color at runtime and I cannot unpack the player obj since it's needed for isntantiation (respawn)

gleaming prawn Jul 17, 2020, 8:06 AM

#

all clients must have the prefabs with the right colors (or possibility to change material sikn colot-tint) - this can also be done with asset bundles, etc

#

Then, when you instantiate, you include the information about the right skin to be loaded, etc.. (you definitely can switch materials, models, etc)

#

There are several different ways to setup such system... But it will be hard to find someone to just write one for you for free.

whole granite Jul 17, 2020, 11:47 AM

Hi guys.

Does the Unity's Transport API has some sort of reliable message queue/buffer?
Basically you cannot send more than 32 reliable messages through the pipeline, as it will end you with an error and the message to be not guaranteed to be delivered.

Tho, simple buffering of these messages for later sending (i.e. wait for the queue to get some free space), would probably make it a lot more reliable.

gleaming prawn Jul 17, 2020, 1:08 PM

#

They are probably using an Int32 bitmask for ACKing

#

that's whyt the 32 queued message limit

jade glacier Jul 17, 2020, 1:25 PM

#

What are these messages your are sending? At a glance it sounds like you are trying to make Unique packets out of each "message"? Rather than serializing a bunch of stuff into a byte[] and making that one message? @whole granite

#

I have no idea what the Unity transport does for batching and such.

whole granite Jul 17, 2020, 1:29 PM

#

Yeah, let say that I want to send more than 32 packets over reliable pipeline. It's totally edge case, tho.

jade glacier Jul 17, 2020, 1:30 PM

#

That is some 32000+ bytes worth of data if you are making efficient use of your packets

whole granite Jul 17, 2020, 1:30 PM

#

Well, technically you don't have to send that much data over single packet (i.e. <1400bytes).

jade glacier Jul 17, 2020, 1:31 PM

#

A single packet for UDP is more going to be in the byte[1200] range to keep it within MTU

#

I assume that 32 packet cap resets once you flush the transport?

#

I am not familiar with that restriction, so not sure what it relates to. Typically with transports you just send, and it keeps pushing them out the door. A mask implies that it is batching your writes into datagrams or something. I really have no idea. I avoid the transport layer. That just all sounds a bit odd.

gleaming prawn Jul 17, 2020, 1:34 PM

#

they probably also slide the window

#

so it keeps shifting the bits as soon as an ack happens, etc

jade glacier Jul 17, 2020, 1:49 PM

#

That would make sense.

graceful zephyr Jul 17, 2020, 4:41 PM

#

it can only have 32 reliavble packets 'in flight' at once

#

which is laughabily small

#

@jade glacier

jade glacier Jul 17, 2020, 4:41 PM

#

I assume that is atypical?

graceful zephyr Jul 17, 2020, 4:41 PM

#

depends on the game, but it makes the library basically useless for reliable sends

jade glacier Jul 17, 2020, 4:41 PM

#

If they were going to be lazy, why not back it with a uint64 at the very least?

graceful zephyr Jul 17, 2020, 4:42 PM

#

it's too little tbh, it needs to handle these cases well

#

just one simple thing

#

I want to send a map from server to all clients when they join, if the map is larger than 1200 * 32 bytes ... i can't.

jade glacier Jul 17, 2020, 4:42 PM

#

That seems pretty fragile yeah

#

If you want bigger you have to build in some kind of metering method that "feeds" the transport slowly and waits for acks?

graceful zephyr Jul 17, 2020, 4:43 PM

#

yes which is just...

#

that's what the transport should do

jade glacier Jul 17, 2020, 4:43 PM

#

defeats the abstraction yeah

#

I would expect my transport to be fire and forget

graceful zephyr Jul 17, 2020, 4:43 PM

#

yes

jade glacier Jul 17, 2020, 4:43 PM

#

weird.

slim ridge Jul 17, 2020, 4:44 PM

#

or stream the map with tcp

graceful zephyr Jul 17, 2020, 4:45 PM

#

yes but that's just

#

then you're adding another complexity

#

it should handle that easily no problem

#

but it doesn't

jade glacier Jul 17, 2020, 4:46 PM

#

This is the current transport layer of the netcode library?

graceful zephyr Jul 17, 2020, 4:47 PM

#

yes

jade glacier Jul 17, 2020, 4:48 PM

#

oh boy.

weak plinth Jul 18, 2020, 7:24 AM

#

what would be the easiest way to handle randomly spawning objects?

#

like events to happen in the map

gleaming prawn Jul 18, 2020, 7:40 AM

#

In which library?

#

Your question is way too broad

weak plinth Jul 18, 2020, 7:57 AM

#

sorry, i cant find the right words

#

what im trying to do is spawn an item at a random position on the server side, instead of the players

gleaming prawn Jul 18, 2020, 8:05 AM

#

What is the library?

weak plinth Jul 18, 2020, 8:13 AM

#

i just wanna start off with 1 object to spawn

#

as i have no idea what a library is

whole granite Jul 18, 2020, 8:31 AM

#

Yeah, that is why I asked about that queue/buffer thingie. @jade glacier @graceful zephyr
Dunno, but I'll probably make my own "feeding" mechanism. But it would be nice for Unity to support this, tho...

#

Probably I'll post something on the forums.

weak plinth Jul 18, 2020, 9:54 AM

#

what does this mean?

📎 unknown.png

#

this is the line of code it's talking about

📎 unknown.png

gleaming prawn Jul 18, 2020, 10:20 AM

#

So, library is photon

#

Best way would be, get a random position, network instantiate from the master client, I'd say

#

If you don't know what that means, than I'm not sure I know how to explainm

weak plinth Jul 18, 2020, 10:21 AM

#

i understand that, any help on my error though?

gleaming prawn Jul 18, 2020, 10:22 AM

#

Your code, line 29 of that script is trying to call functions in a null reference

Should be self explanatory

yea but idk what part of https://cdn.discordapp.com/attachments/497874116246896640/733985138530189393/unknown.png is causing the error

gleaming prawn Jul 18, 2020, 10:23 AM

#

We'll, it's your code

#

Probably photon view is null?

#

Debug the code

weak plinth Jul 18, 2020, 10:26 AM

#

that was it, thanks

weak plinth Jul 18, 2020, 7:02 PM

#

Guys

#

Help please?

#

how i can duplicate a object

#

properly with PhotonView

#

        private void CloneGameObject(GameObject GameObject)
        {
            DebugLog("Found A Test GameObject  :" + GameObject.name);
            var obj = PhotonView.Instantiate(GameObject, CenterOfPlayer() + DistanceVector, Player.field_Internal_Static_PlayerField_0.transform.rotation);
            if (obj != null)
            {
                obj.transform.SetParent(null);
                DebugLog("Spawned A Copy Successfully!, cloned " + obj.name);
            }
            else
            {
                DebugLog("Failed to clone object, is null!");
            }
            return;
        }

#

this is how im instantiating the object

#

but

#

there's this error

jade glacier Jul 18, 2020, 7:34 PM

#

Instantiate takes the name of the gameobject, and uses that name to find the Prefab in a Resources folder. What you are doing there looks like its trying to do something different. Can't comment on the error, since I can't see the trace of what line in cs is causing that.

weak plinth Jul 18, 2020, 7:34 PM

#

the error pops up

#

when you try to instantiate with UnityEngine.Instantiate

#

because the cloned object in photonview has the exact same key and it doesn't allow it

#

soo the object is not grabbable at all

#

but the original one is it.

jade glacier Jul 18, 2020, 7:35 PM

#

You are trying to do something that Instantiate isn't really meant to do is what it looks like at a glance.

weak plinth Jul 18, 2020, 7:35 PM

#

yeah

#

how im supposed to instantiate a gameobject then?

jade glacier Jul 18, 2020, 7:35 PM

#

By putting the prefab in the resources folder at design time

#

that way all clients have the exact same prefab to work with

weak plinth Jul 18, 2020, 7:36 PM

#

.... is a mod boi, the client has a API that im using

jade glacier Jul 18, 2020, 7:36 PM

#

Can't speak to that

weak plinth Jul 18, 2020, 7:36 PM

#

but when im grabbing the object

#

it doesn't let me interact with it

#

because of that error

jade glacier Jul 18, 2020, 7:36 PM

#

Not sure what grabbing the object means, but that is something outside of the Photon networking problem it sounds like.

#

I wouldn't be trying to "grab" anything while you have a critical error.

weak plinth Jul 18, 2020, 7:37 PM

#

is not a critical error if the object shows up

#

but photonview doesn't allow me to interact with it.

jade glacier Jul 18, 2020, 7:37 PM

#

If you have red text in log, you have a problem you are going to want to resolve first

weak plinth Jul 18, 2020, 7:38 PM

#

that is a white error, not a red error luckily

#

but is annoying that i can't interact with it and i want to fix that

#

if there's a way to convert that object into a prefab throught script i would do that

jade glacier Jul 18, 2020, 7:38 PM

#

I mean, yeah - you got some bugs to work out.

#

You can get into instantiation with your own RPCs

#

and not use the PhotonNetwork.Instantiate

#

But you will need to send all info that is required to other clients.

#

nothing just "replicates", you have to parse out what info is needed that other clients won't know about the object, and send that, and apply it on them manually.

weak plinth Jul 18, 2020, 7:40 PM

#

yeah, but RPC doesn't have much

jade glacier Jul 18, 2020, 7:40 PM

#

Typically you try to avoid that, and make your prefab that you spawn from standard. Then you only send messages about "variations" to that object.

weak plinth Jul 18, 2020, 7:40 PM

#

how im supposed to clone a object with RPC?

jade glacier Jul 18, 2020, 7:41 PM

#

by deserializing and serializing whatever needs to be to make that happen. It isn't basic and will require some understanding of object serialization and such.

#

You generally don't "clone" objects with networking. You typically have a starting prefab, and then you just network changes to that prefab... such as color, mounted weapons etc.

weak plinth Jul 18, 2020, 7:43 PM

#

is a test

#

is a ball

#

not much rn

jade glacier Jul 18, 2020, 7:44 PM

#

Is your ball a prefab in a resources folder?

weak plinth Jul 18, 2020, 7:44 PM

#

is made with script

#

not in the editor

jade glacier Jul 18, 2020, 7:46 PM

#

Then you are pretty much on your own yeah. That is outside of the MonoB tools that Photon gives you to work with. You will need to write your own serialization and deserializaton probably.

weak plinth Jul 18, 2020, 7:47 PM

#

C_C

jade glacier Jul 18, 2020, 7:47 PM

#

You can make your own instantiation methods and such, but its all going to be a bit more advanced than PhotonNetwork.CloneMyThing(mything)

weak plinth Jul 18, 2020, 7:48 PM

#

..........

#

WHY

jade glacier Jul 18, 2020, 7:48 PM

#

Why what?

weak plinth Jul 18, 2020, 7:48 PM

#

Why is soo hard

#

the error says the object already exists in a list

jade glacier Jul 18, 2020, 7:48 PM

#

Because serializing undefined GameObjects is not trivial

#

If you have produced an object on all clients that you are treating as the gameobject starting point, you can instantiate that and then make variations to it.

#

But none of this is trivial.

weak plinth Jul 18, 2020, 7:49 PM

#

is possible to destroy that object from photonview ?

#

since that is the only issue with instantiated gameobject, that photonview interferes

jade glacier Jul 18, 2020, 7:49 PM

#

I have no idea, I don't know what you have going on. Anything is possible with coding though.

weak plinth Jul 18, 2020, 7:50 PM

#

        private GameObject RemovePhotonFromObject(GameObject originalobj)
        {
            var PhotonLessObject = UnityEngine.Object.Instantiate(originalobj);
            if (PhotonLessObject != null)
            {
                PhotonView[] photonViews = PhotonLessObject.GetComponentsInChildren<PhotonView>(true);
                if (photonViews != null && photonViews.Length > 0)
                {
                    for (int i = 0; i < photonViews.Length; i++)
                    {
                        PhotonView pv;
                        if ((pv = photonViews[i]) != null)
                        {
                            UnityEngine.Object.DestroyImmediate(pv);
                        }
                    }
                }
                return PhotonLessObject;
            }
            return null;
        }

#

but it doesn't work perfectly

jade glacier Jul 18, 2020, 7:51 PM

#

can't say, too much code not in front of me to say if you are on a good path or a bad one.

#

You are just definitely not doing a standard PN.Instantiate() here.

#

PhotonView.Instantiate() is not a thing btw

#

You is just GameObject.Instantiate() ... it is derived from MonoBehavior so you are just seeing the MonoB Instantiate method there.

#

PhotonNetwork.Instantiate is what you use for network instantiation.

weak plinth Jul 18, 2020, 7:53 PM

#

Yeah, but it asks for a prefab

#

this game aint using prefabs

jade glacier Jul 18, 2020, 7:54 PM

#

I'm not sure what your question is really sorry.

weak plinth Jul 18, 2020, 8:43 PM

Hi I’m in unity 5.6.0 and I got problem I’m coding a multiplayer game in unity and it’s multiplayer both characters work and can move independently on the client but only the lan host registers on all screens btw it’s C#

cedar cloak Jul 20, 2020, 9:01 AM

#

how can I just create a "normal offline" room using Photon? I need to create a tutorial scene but since now is all tied up to Photon services it's really hard to do a stardand scene

weak plinth Jul 20, 2020, 9:17 AM

#

just remove all the photon stuff related to the room

cedar cloak Jul 20, 2020, 9:38 AM

#

problem is that the player is linked to photon references too

gleaming prawn Jul 20, 2020, 9:45 AM

#

Isn't there the offline mode?

#

I remember PUN classic has it

#

Not sure about PUN2

#

With Offline mode you can just use the code as it is, it will work the same as a local regular unity game

#

Maybe @jade glacier or @stiff ridge can chime in...:)

weak plinth Jul 20, 2020, 11:01 AM

#

hope so 🤞

jade glacier Jul 20, 2020, 11:58 AM

I would start by reading about offline mode yeah, see if it's what you are looking for.

cedar jacinth Jul 20, 2020, 2:34 PM

Unity 5.6.0 : my problem that I posted about was never solved so I’m going to post again in more detail.
My lan character is registering movement across all connected games I had 3 games open and the lan seemed to be moving on all but when I moved on a client it’s movement only registered on its own screen

gleaming prawn Jul 20, 2020, 2:39 PM

#

Unity 5.6: which library are you using for this?

#

Is it PUN/Photon, UNet, etc?

cedar jacinth Jul 20, 2020, 2:41 PM

#

Library?

#

Sorry @gleaming prawn is really new to code meaning player movement which I wrote 2 days ago was my first working piece of code

gleaming prawn Jul 20, 2020, 2:43 PM

#

What is the networking livrary you are using?

#

There are several different ones...

#

My lan character is registering movement across all connected games
You must be using some networking solution to have this.. Was it the old, abandoned UNet (the last official attempt from Unity to create a default networking package)?

#

If it's anything official from Unity, you'll probably not have any help here (UNet is not supported anymore, was never finished... There's an open source project which took the original UNet and moved on - called Mirror)

#

I suggest you study a bit more, and also: upgrade from 5.6 at least to one of the LTS versions, either 2017.4 or 2018.4

#

IMHO

frosty crystal Jul 20, 2020, 9:36 PM

#

Hello. I could not find the solution. Thanks in advance for your responses.
In pun2, In my scene, the game is being creating by script as random. How can I implement exctaly the same room to my remote player? Should I transfer gameobjects to remote client? If it is, how? If there is another solution how? just giving a header to google it is enough for me. Thanks.

jade glacier Jul 20, 2020, 9:43 PM

#

Have you done the tutorials for Pun2? (I assume you mean Pun2 when you say Photon).

#

They demonstrate network instantiation of objects and how you should be doing it.

frosty crystal Jul 20, 2020, 9:47 PM

#

Have you done the tutorials for Pun2? (I assume you mean Pun2 when you say Photon).
@jade glacier I did not watch tutorials associated with that I think. check it out now.

jade glacier Jul 20, 2020, 9:48 PM

#

I wouldn't watch them, that won't really drive home how things work well enough. You really want to complete a few tutorials before trying anything of your own. You won't guess correctly.

spring crane Jul 21, 2020, 6:00 AM

#

@frosty crystal If you mean world generation, you probably wanna use some sort of seed as the base for the randomness. You can then just send the seed and let each client do the generation

#

At least the static parts

spice steeple Jul 21, 2020, 3:15 PM

#

I have a question, I don't know if any of you ever used mirror (multiplayer package), but I'm trying it out right now and I was wondering how do you host a server on your PC using and ip instead of localhost so other people that are not on our network can also join

gleaming prawn Jul 21, 2020, 3:16 PM

#

you should join their own discord

spice steeple Jul 21, 2020, 3:16 PM

#

Smart I'll do that right now

gleaming prawn Jul 21, 2020, 3:16 PM

#

But what you are looking for is punch-through + relay fallback options. I think they have this through some third party software

drowsy owl Jul 21, 2020, 3:17 PM

#

You can also have them connect to your public ip, the host will need to port forward the port you are receiving connections on

gleaming prawn Jul 21, 2020, 3:18 PM

#

port forward, you mean with the router?

spice steeple Jul 21, 2020, 3:18 PM

#

Interesting, how would i go about port forwarding, is it hard?

gleaming prawn Jul 21, 2020, 3:18 PM

#

This is not recommended at all for several several reasons, but sure.. If it's just a playground thing

#

you need to configure in the Router

#

It's very "nerdy" to do this, as UpNP (a protocol for automating that) is unsafe and almost not supported anymore AFAIK.

#

Modern method for this is STUN punch through

#

relay fallback

#

It is what Steam networking and Photon Bolt both use...

#

Port forwarding should be fine for some basic testing.

spice steeple Jul 21, 2020, 3:20 PM

#

do you maybe have any video or article on this topic that i can read on so I understand it a bit more because its my first time trying something like this

#

would u say that port forwarding is easier but unsafe?

gleaming prawn Jul 21, 2020, 3:20 PM

#

if this is first time, I'd not start with it

#

It's NOT easier... It requires you to configure in your router

#

SO there's no "google it" that's generic... Each router has it's own user manual

drowsy owl Jul 21, 2020, 3:21 PM

#

Yeah, for an actual game you wouldnt want to force your users to port forward because it needs to be done on your router, I remmember having to learn how to port forward to make a minecraft server for my friends back in the day. For if you want to skip the fuss for some playground stuff like Erick mentions, then portforwarding will be easier than doing NAT punchthrough

gleaming prawn Jul 21, 2020, 3:21 PM

#

And it will only work IF your ISP gives your router a real IP (some use double nat now, which makes things more complicated)

#

Easy is relative...:)

#

For a first timer... Photon is easier... Honestly... Mirror is easy for the LAN case though

spice steeple Jul 21, 2020, 3:22 PM

#

ah ill try to use photon then see how that goes

#

Thanks for the tips

#

means alot

gleaming prawn Jul 21, 2020, 3:22 PM

But you should join Mirror's Disrcod

spice steeple Jul 21, 2020, 3:22 PM

Yea did that right now

gleaming prawn Jul 21, 2020, 3:22 PM

#

they might answer you with more details

drowsy owl Jul 21, 2020, 3:23 PM

#

Looks like for mirror it is not out of the box, you need to do the NAT punchthrough yourself. I bet somebody on the mirror discord already has code you could use though

spice steeple Jul 21, 2020, 3:24 PM

#

Thanks ill look around in there discord

frosty crystal Jul 21, 2020, 7:05 PM

@frosty crystal If you mean world generation, you probably wanna use some sort of seed as the base for the randomness. You can then just send the seed and let each client do the generation
@spring crane I see. But ı want to do it randomly. Let me explain. as you see in the picture below, I want to make all the boxes randomly. But I dont know how to do. If I do it randomness how do I do?

📎 games_like_bomber_blast_bomberman_game_for_nintendo_switch.jpg

#

📎 Capture.JPG

#

When I do it randomly how can I send all the game objects to remote clients. If there is no solution, how can I do with seed without using random.

#

In the documentation mentions about sending seed and changing custom room properties, so the clients can implement with in their own scene.

gleaming prawn Jul 21, 2020, 7:13 PM

#

You should definitely just send the seed, and generate the same random sequence, hence the map as well, in all clients

#

Also, Bomberman is a good example of a game that works well only with deterministic predict rollback (aka rollback netcode). Using interpolation in Bomberman is sacrilegious

#

:)

#

Trying to sync info about all these boxes is overkill, just use determinism....:) Specially because you should definitely not use physics engines and shit like that for such game, it's grid based, very.clean and straightforward implementation.

frosty crystal Jul 21, 2020, 7:21 PM

Ok. Erick, I have a question, I am kind of new in unity.

#

After every boxex's instantiation, I will determine the type of the box, and add to a dictionary, Right? After all, to the hashtable...

📎 Capture.JPG

gleaming prawn Jul 21, 2020, 7:33 PM

#

You need to guarantee your random is deterministic in the first place

#

If this is your first game, do not try to make it multiplayer

#

That's the only reasonable advice I can say...

#

What I said before is valid, but requires a lot of experience

You'll find better help in the Mirror discord, but I see a few errors. CharacterClasses isn't a mirror-serializable type, [Command] method names have to start with Cmd.

jade glacier Jul 22, 2020, 10:00 PM

#

That is what they are for yeah @cedar cloak

cedar cloak Jul 22, 2020, 10:14 PM

#

strange, I'm trying to make some sort of killfeed so if the player dies it sends to everyone (thorugh an RPC) a method that create a message on the HUD, but doesnt seems working...

jade glacier Jul 22, 2020, 10:15 PM

#

Dunno

#

Sounds like you got a bug.

cedar cloak Jul 22, 2020, 10:18 PM

#

are RPC called like this? photonView.RPC("Method", Target, *eventualy variables*);

cedar cloak Jul 22, 2020, 10:36 PM

#

can I call an RPC on another script right'

#

?

jade glacier Jul 22, 2020, 10:37 PM

#

I never use them, so I would just end up referring to the manual, but that is the concept yeah.

cedar cloak Jul 22, 2020, 10:58 PM

#

tought to explain but i fixed it 🙂

lunar sage Jul 23, 2020, 12:06 AM

#

is there a way to share information with every player in photon pun 2? ping me if you know

jade glacier Jul 23, 2020, 12:51 AM

#

Typically with an RPC @lunar sage

lunar sage Jul 23, 2020, 12:52 AM

#

yes i am gnna do that, didnt know what it was called

#

is threre a way to do that with variables @jade glacier

jade glacier Jul 23, 2020, 1:17 AM

#

Just through the RPC. I have added syncvars with the SNS extension library for Pun2, but that is still in beta.

lunar sage Jul 23, 2020, 1:27 AM

#

oh

#

would getter and seter functions work

jade glacier Jul 23, 2020, 1:30 AM

#

It works like the Unet/Mirror Syncvar, only using tick based timings.

#

i tried using pun but the physics were slow and unresponsive

lunar sage Jul 23, 2020, 2:55 AM

#

i dont think it affects the physics

gleaming prawn Jul 23, 2020, 8:41 AM

#

@jaunty burrow definitely photon Quantum

#

Truesync is a discontinued product (also deterministic predict rollback like quantum, but with a -wrong- MonoBehavior-based architecture, so didn't reach the desired performance),

#

For physics-based interactions where accuracy is required, there's nothing to really compete with quantum...That's what it is.

#

@lunar sage PUN2 would not be ideal for physics-based interactions.

#

Neither bolt.

cedar cloak Jul 23, 2020, 10:19 AM

#

I'm using a particle system on the guns to make a flash when I shoot, problem is that when I do it all nozzle flashes

#

@gleaming prawn bolt is a visual scripting language, not sure what it has to do witht his

gleaming prawn Jul 23, 2020, 11:39 AM

#

@lunar sage Photon Bolt is a networking library.. Was created LONG before bolt scripting language FYI...:)

lunar sage Jul 23, 2020, 11:39 AM

#

oh

#

im dumb

gleaming prawn Jul 23, 2020, 11:39 AM

#

I never understood why Unity let the scripting language use that name, as it was taken (Bolt networking was a package in there before)

lunar sage Jul 23, 2020, 11:39 AM

#

ye

#

a lot of ppl were talking abt the bolt viual script so i thought he was

gleaming prawn Jul 23, 2020, 11:40 AM

#

Bolt (the net library) is a client-server, fully fledged tool... Well praised by people who use it, etc. For the right games (FPS, TPS, Action Adventures, etc), it is possibly the best tool in Unity (subject to opinion, of course).

#

But for games where the main focus is physics interaction and accuracy is necessary, Quantum is (arguably) the best.

jade glacier Jul 23, 2020, 11:46 AM

#

The main thing people should get from all of this is that Bolt and Quantum are you ONLY complete networking stacks.

#

Pun2, Mirror, Forget, MLAPI and the various transports will require you to get your hands dirty quite a bit more in the business of working out the paradoxes that come with state transfer.

#

Any Transform/Animator syncs they provide are indicated as "Reference only" and are not particularly good. And none of them are tick/simulation based. So you are on your own to wire that up.

jaunty burrow Jul 23, 2020, 5:09 PM

#

@gleaming prawn is quantum free?

jade glacier Jul 23, 2020, 5:35 PM

#

Quantum isn't for hobbyists no. Last I was aware it costs $1000/mo just to be working with it. The target audience is funded studios/projects.

jade glacier Jul 23, 2020, 9:06 PM

#

Yeah, stop whatever you are working on. Spend half a day getting git installed and learning the basics.

#

Programming without a repo is suicide.

terse relic Jul 24, 2020, 1:25 AM

#

so i cant use photon free for an fps game then

#

cuz explosions use physics

weak plinth Jul 24, 2020, 1:45 AM

#

you can have physics in games without determinism. Just gets a bit complex

lunar sage Jul 24, 2020, 2:13 AM

#

cuz explosions use physics
@terse relic make ur own explosions

#

w8 @weak plinth what physics things dont work in photon pun 2

jade glacier Jul 24, 2020, 3:31 AM

#

It depends what you mean by physics really.

#

State Transfer involves the authority version running some form of physics or simulation, and then broadcasting that state to the players. Physics themselves aren't networked.

#

What you likely are asking for, the only library that will make physics appear in perfect agreement between clients is Quantum.

#

With state transfer libraries (Bolt, Pun2, Mirror, etc) Physics occur on one client or on the server, and the results are replicated to others not as physics, but as transform states.

Hi. In pun2, when I create room, in OnJoinedLobby, my game scene is being opened. But in the game scene, function the OnJoinedRoom is not working? What may cause it?

jade glacier Jul 24, 2020, 11:20 AM

#

"Not working" ?

#

What messages are you seeing in the log?

#

Do the example scenes in the photon folder work? Like the Asteroids demo? @frosty crystal

lunar sage Jul 24, 2020, 12:17 PM

#

@jade glacier this wont cause much issues in a game with character controller movement right

#

and do raycasts get affected

jade glacier Jul 24, 2020, 12:18 PM

#

Way too vague really for me to even guess at the right answer for you sorry.

lunar sage Jul 24, 2020, 12:19 PM

#

like would this affect character controller

gleaming prawn Jul 24, 2020, 12:19 PM

#

@floral turtle this "add on" is super old, and does not even mention that Bolt now has a free version... I doubt it still works, as it didn't get updated since 3 years ago.

jade glacier Jul 24, 2020, 12:19 PM

#

You have to clearly define what you mean by "networking physics" before you can answer questions about what can and can't happen

gleaming prawn Jul 24, 2020, 12:19 PM

#

ALso, you can join Bolt's official discord and check the community there, they are very welcoming to newcomers.

jade glacier Jul 24, 2020, 12:20 PM

#

I WOULD NOT even think about any of this unless you have a few basic networking games made.

lunar sage Jul 24, 2020, 12:20 PM

#

i didnt say "networking physics"

jade glacier Jul 24, 2020, 12:20 PM

#

Then I might be confusing conversations, I'm not sure what we re discussing sorry.

lunar sage Jul 24, 2020, 12:20 PM

#

i mean would the issues u talked abt earlier affect character controller or no

gleaming prawn Jul 24, 2020, 12:21 PM

#

Everything networking affects character controllers...:)

#

You can just do a very naive implementation (using PUN2, for example), so you control your local KCC and sync it's movement.

lunar sage Jul 24, 2020, 12:21 PM

#

i think im confusing myself

gleaming prawn Jul 24, 2020, 12:21 PM

#

And not do any lag compensation for raycasts

#

But the more you get into networking you'll see the devil in the details.

#

And understand why there's a lot more involved into making a good game (that feels good, fast and fair to play)

lunar sage Jul 24, 2020, 12:24 PM

#

yeah cuz the thing is like a quarter of a second delayed, even tho both clients were on the same device

#

or maybe i just have bad internet, i have no idea

gleaming prawn Jul 24, 2020, 12:30 PM

#

For mirror, I suggest you join their own Discord server

fading mason Jul 24, 2020, 12:31 PM

im stupid forgot i was in there ty

frosty crystal Jul 24, 2020, 3:03 PM

#

What messages are you seeing in the log?
@jade glacier I have noticed my issue. why I do not know but, I thought, even after changing scene, the OnJoinRoom is supposed to be run. But it is being called just once in the same scene. Not to the other scenes.

jade glacier Jul 24, 2020, 3:05 PM

#

It is a callback, so it will only fire when you join a room, and the callbacks that fire will only be the callbacks you registered.

#

If any scene objects aren't loaded, they wont have any instances, nor will they have registered any classes.

haughty blade Jul 24, 2020, 9:09 PM

Hey so... how incredibly hard would it be for me to write server authoritative netcode for VR that actually feeds in 3 rigidbody's vector info as input per client (head + 2 hands) as Vector3 position, Vector3 linearVelocity, Quaternion rotation, Vector3 rotationalVelocity? Is that a lot (too much?) of data to feed from client to server considering generally most games just need a Vector 2 for mouse cursor and like 4 bits for WSAD?
How much should I truncate the Vector 3's by before I will crash everything to the ground? What tick should I be going for?
Like how often should I send input considering the much higher input requirements? And any recommendations on server tick rate? I'm going for multiplayer melee (sword).
Also - has anyone successfully set up Unity with wireless ADB in a way that you can Build and Run wirelessly? I mean, on an Oculus Quest

Help needed. If I have networkid stored as string, how can I find gameobject with that netid? I tried NetworkServer.FindLocalObject() but how do I convert from string back to networkid?

jade glacier Jul 25, 2020, 3:32 PM

#

Should we first ask why its a string?

haughty blade Jul 25, 2020, 3:46 PM

#

@buoyant carbon I think what @jade glacier is saying is that the return type from FindLocalObject() should be GameObject

#

📎 unknown.png

#

From the GameObject itself you should be able to use its own member functions to find out whatever you need about the object you've pulled up, or interact with it

jade glacier Jul 25, 2020, 3:55 PM

#

The netId has no real reason to ever be a string, wondering what could have led to that.

vapid leaf Jul 25, 2020, 4:09 PM

#

so i have a singleton with a script variable which is supposed to only have 1 player play as one character so players can switch between characters so the variable should be global yet i cant get it to be global on all clients yet i can get 2 players on 1 character. Anyone have any fixes? This is in mirror but i am debating if i should just use syncEvents instead tho

jade glacier Jul 25, 2020, 4:17 PM

#

That sounds like a job for syncvars.

buoyant carbon Jul 25, 2020, 5:46 PM

#

The netId has no real reason to ever be a string, wondering what could have led to that.
@jade glacier @haughty blade thanks, I backtracked all the old methods to find why it was originally done so, and there really was no reason for it at first place. Just bad code. Thanks for the help.

For local I'm using mirror and I'm pretty sure you can also use mirror for online p2p connection but I'm not exactly sure how

No license either so u can use it commercially worry free

worldly cedar Jul 27, 2020, 2:47 AM

Im finding that I have 'left over' packets in my UDP socket between connections. So, if I connect once, then disconnect, then connect again, any packets I hadnt received in the meantime seem to queue up to be consumed.

Now, from what I've read, a NetworkStream doesnt have a buffer, so Flush on that wont actually do anything, but what I did is this:

if (flush)
    {
        while (client.Available > 0)
        {
            client.Receive(ref groupEP);
        }
        flush = false;
    }

Where flush is a bool, client is a UDPClient and groupEP is the IPEndpoint. Is there anything particularly wrong with doing it this way? I am using ReceiveAsync on my other calls, but thats more a structure thing, this is running on a separate thread so it wont block the game thread.

gleaming prawn Jul 27, 2020, 11:28 AM

#

Unity's own is slpha/broken state.

#

Not close to being usable... Also very tied to a very specific networking model so far (may evolve later, but who knows)

#

By photon you probably mean PUN, right? There are several options (from photon, like Quantum, Bolt and PUN2) or from others like Mirror (open source followup to unity's deprecated UNet), etc

tidal zealot Jul 27, 2020, 11:35 PM

#

okay, So i'm having a problem that I think this might be the right place to post it... I'm not too sure exactly how to phrase it nor do I know where the problem is in my code, but I'm doing an FPS and have an effect of the current prototyped pistol that allows it to recoil upwards when a shot is taken before then returning to it's initial position that it was held in... THIS works, just not over the 'server' I made with PUN, I've got all the movement and shotting synced apart from this one issue

#

so now it looks as though the player that has shot has the gun constantly rotation around him hahaha

#

So if anyone thinks that they might be able to help me, please PM me... I've been struggling for a lot of today on this one issue and don't really understand what to do :/ Thanks in advance! haha

@thorn kestrel

there's someone have a knowledge about multiplayer?
Yes, several
and games thats u should connect to the server not to the host?
But this question is difficult to even understand.

#

Please, ask a more specific technical question, then you might get a proper answer

#

@tidal zealot I'd just trigger an animation for that when I get the information about the shot (on the other clients)
If you want to consider the recoil for the aiming on the next shot, use the bone-animation position/orientation as part of the shot parameters...

#

It's a bit of a complex topic (to make that influence gameplay), but just showing it should be straightforward with animation

jade glacier Jul 28, 2020, 3:04 PM

#

It looks like your non-authority versions of player objects is a non-kinematic physics objects. They typically need to be kinematic on other clients, and they get moved with the NetworkTransform sending updates from the Authority version to all other clients.

#

If you are using physics, only the one with hasAuthority == true should be affected by physics (set to non-kinematic).

hi

#

do you have any tutorial about parsing apis for unity?

dusty salmon Jul 28, 2020, 6:24 PM

#

anyone used UNet, been getting the hang of it, ive built a custom server browser using it and ive also built added an auto search system, can someone help me with the logic atm the program list all the matches or trys to list 200 if there are no matches we create a match, if there are matches then pick a random match from the list and join, these feels to simple to work properly

gleaming prawn Jul 28, 2020, 6:27 PM

#

@thorn kestrel in that case my answer is also clear: yes...:)

thorn kestrel Jul 28, 2020, 6:31 PM

#

@gleaming prawn ok so how to make it u have some yt tutorial or somethin ?

jade glacier Jul 28, 2020, 6:38 PM

#

Erick is saying that you need to post specific questions here that are answerable. "Teach me networking" is a bit much, considering it is something that typically takes a few years to get a really good handle on. @thorn kestrel

#

Try out the public libraries that are an option. Mirror, Pun2 and Bolt are pretty typical starting points.

gleaming prawn Jul 28, 2020, 6:39 PM

#

A server can be for many things, so there are several YouTube videos, yes. But your question is still way too vague, as stated by emotitron.

How can I make photon work with ObjectPool? I know I can instantiate with it, but I want to have my objects preinstatiated to improve performance. (Also, it's a test and I want to impress them)

craggy bear Jul 28, 2020, 10:27 PM

#

Also, is there anything special to photonView.IsMine? I can freely move 2 players, but their position isn't updated on other clients.

#

And when I say this (if statement), it's updating the wrong client...

📎 unknown.png

#

if I reverse this if(!photonView.IsMine) it works fine

#

yes, they do have photon view components.

📎 unknown.png

#

I am also moving them by their transforms, not by physics.

you have the transform views on them yea?

Yep, it's in the screenshot.

@thorn kestrel mirror is open source and free... But if you plan to host servers, these will never be free, and also a matchmaking system to list active server, etc, these are services you normally have to pay for

@gleaming prawn oh, so there's no free matchmaking system ?

gleaming prawn Jul 31, 2020, 9:11 AM

#

@thorn kestrel Epic Online Services promises to be "free"

#

Although these things always come with strings attached...:)

#

If they offer options for matchmaking, I've not yet tried them.

#

The one from steam is also free, but it's only useful if you plan to sell the game there (PC only, etc) - which is give-me-30%-of-revenue "free"

#

Google released a free (very basic and raw) SDK for matchmaking... But you'd need to HOST it somewhere (which is not free, of course) https://github.com/googleforgames/open-match

im trying to sync a ball between instances

#

📎 unknown.png

#

is this the right way to do it

stiff ridge Jul 31, 2020, 1:48 PM

#

It's a simple way to do it. if multiple players interact with the physical objects, there will be problems like objects passing through one another.

jade glacier Jul 31, 2020, 2:06 PM

#

Balls are one of the bigger challenges in networking, because they expose the latency of the network, and the disagreements between clients timings.

#

Most ball type games tend to use extrapolation rather than interpolation.

#

Most of your networking libraries work on state transfer and interpolation, so they are not out of the box good for dealing with players interacting with shared objects or one another.

#

I would not recommend a game like that as your first networking attempt.

safe lynx Jul 31, 2020, 3:42 PM

#

XD im not going to do a ball type game

#

i just need a way to sync an obj

jade glacier Jul 31, 2020, 5:11 PM

#

may have just misinterpreted your "sync a ball" then

#

I see "Grab" in your components, which leads me to believe that players can and will be competing for control of that object though, which is the same general problem.

weak plinth Jul 31, 2020, 6:10 PM

#

Hey! What networking solution do you recommend for a game where the client is also the host? I saw photon and I dont really like that I have to use its servers. Also saw that UNet is being deprecated, and that Mirror exists, but what do you recommend?

gleaming prawn Jul 31, 2020, 6:13 PM

#

photon (PUN2)... or photon Bolt.

#

Mirror has p2p as well, it seems... But I'm not familiar with how to do that. For LAN games, then Mirror should be ok

#

I mean. I read what you said

weak plinth Jul 31, 2020, 6:14 PM

#

Yeah, I have been the last couple of days trying to use mirror, but I dont find really good tutorials (Almost everything is the basic, just connect)

gleaming prawn Jul 31, 2020, 6:15 PM

#

But I would not rule-out tools used by successful games because "you do not like" a certain aspect

jade glacier Jul 31, 2020, 6:15 PM

#

Pun2 is the easiest in the sense that you have no concerns about punch-through and such. But Mirror and similar give you a proper server option.

weak plinth Jul 31, 2020, 6:15 PM

#

Yeah sorry, I forgot to add that it will use LAN connection, so I cant rely in photon servers

gleaming prawn Jul 31, 2020, 6:15 PM

#

There's a few reasons why the photon products are used...:)

jade glacier Jul 31, 2020, 6:15 PM

#

Pun2 is relay, so its easier to deploy, but a little different to develop for.

gleaming prawn Jul 31, 2020, 6:15 PM

#

If it's LAN-ONly...

#

then go for mirror

jade glacier Jul 31, 2020, 6:16 PM

#

Yeah, Photon products are not going to be something you want to play with if you are making a lan hobby project. Go Mirror.

weak plinth Jul 31, 2020, 6:16 PM

#

Do you recommend any tutorials about Mirror?

jade glacier Jul 31, 2020, 6:16 PM

#

The mirror discord is the place to be for all of that.

weak plinth Jul 31, 2020, 6:17 PM

#

Okay, then I will try it, thanks guys

grizzled narwhal Jul 31, 2020, 6:17 PM

#

I use MLAPI but this seems really unpopular around here

weak plinth Jul 31, 2020, 6:19 PM

#

Do you recommend that before Mirror?

gleaming prawn Jul 31, 2020, 6:19 PM

#

I really have not studied the MLAPI much

#

I mean, I tend to see the most opposite tiers:
high level: fully fledged netcode APIs, like quantum, pun, mirror, bolt, etc
low level: transport layers like steam, photon realtime, etc

#

I see here it has high level concepts in it...

#

From a first view it seems to be based on the same concepts as Mirror/Unet...:) Hmm... That does not play on its favor...

#

@grizzled narwhal does it have scoping, scheduling, client-side-prediction and lag compensated raycasts like Bolt? These are thing it came with since 2015...

#

I find a bit of a bummer that all attempts to build a networking layer fall short of offering these basics...

grizzled narwhal Jul 31, 2020, 6:25 PM

#

No idea what scoping and scheduling is 😅 . Its a mid level api so doesnt really have client side prediction either -> you'd have to build it yourself

gleaming prawn Jul 31, 2020, 6:25 PM

#

hmmm

grizzled narwhal Jul 31, 2020, 6:26 PM

#

It has low level and boxed rpc's and synced vars

gleaming prawn Jul 31, 2020, 6:26 PM

#

I mean, I forgot to mention delta compression, etc

grizzled narwhal Jul 31, 2020, 6:26 PM

#

Yeah I would have to build that myself

gleaming prawn Jul 31, 2020, 6:26 PM

#

IMHO it's a bit counter productive, if you are trying to build a GAME

#

If you want to learn how to create a proper networking API, could be fun

grizzled narwhal Jul 31, 2020, 6:27 PM

#

Yeah . Atm I just compress pos, velocity, rotation in my custom script and rpc them over with udp

#

Not the best system ever build but it works ;)

gleaming prawn Jul 31, 2020, 6:29 PM

#

Why would MLAPI be better than Mirror, for example?

#

Gives more access to lower level stuff? Just that?

grizzled narwhal Jul 31, 2020, 6:31 PM

#

Yeah. He also claims that its more memory efficient (everything is pooled) and it doesnt launch 1 thread / user

jade glacier Jul 31, 2020, 6:31 PM

#

I would break those layers out a bit more even.

Full stack is Quantum and Bolt
NetEntity message wrappers would be Pun2, Mirror, MLAPI, etc
Transport - messages and connections only

#

MLAPI and Mirror will get you about the same results, with minor annoyances related to choices either make, but they do the same thing.

clever silo Jul 31, 2020, 6:33 PM

#

Personally I wouldn't touch anything which does 1 thread / user, or TCP as a default, and the last I checked, Mirror did both of those

jade glacier Jul 31, 2020, 6:33 PM

#

If you are chasing "efficiency" then any of these libraries should be off the table. Only Bolt and Quantum actually will get you there for that.

gleaming prawn Jul 31, 2020, 6:33 PM

#

That's a good break-down @jade glacier

jade glacier Jul 31, 2020, 6:33 PM

#

You typically want one thread @clever silo

#

Treads in deployment = money

clever silo Jul 31, 2020, 6:33 PM

#

Yes, I was saying you don't want 1 per user

gleaming prawn Jul 31, 2020, 6:33 PM

#

it depends @jade glacier

grizzled narwhal Jul 31, 2020, 6:33 PM

#

I just skimmed the docs of bolt and this entity crearing ui stuff looks a bit weird to me imho

gleaming prawn Jul 31, 2020, 6:34 PM

#

Kylotan is correct, 1 per user is really BAD

grizzled narwhal Jul 31, 2020, 6:34 PM

#

And mirror does that

gleaming prawn Jul 31, 2020, 6:34 PM

#

If it's a game for like 4 players, fine

jade glacier Jul 31, 2020, 6:34 PM

#

fholm was fighting with that for quite a while, dealing with making use of threads and not getting enough benefit for the potential cost to devs. Not sure how that played out with Quantum @gleaming prawn

#

But that was for his 100+ connect engine attempt

gleaming prawn Jul 31, 2020, 6:35 PM

#

Quantum is a different beast

clever silo Jul 31, 2020, 6:35 PM

#

In my experience, you can sometimes get some benefit from threads, but in many cases the operating system and the network adapter do a perfectly good job of batching stuff up while you deal with it. You're often better off using your cores elsewhere

jade glacier Jul 31, 2020, 6:35 PM

#

yeah, no server requirement @gleaming prawn

#

So it will take any CPU it can get I am sure

gleaming prawn Jul 31, 2020, 6:35 PM

#

For the game simulation we do run multiple threads (like Unity's job system - we actually hook up to Unity's job system on unity clients)

#

but it's just the right amount for the target hardware, othjerwise it's useless overhead

weak plinth Jul 31, 2020, 6:36 PM

#

is quantum based on ECS or different thing entirely?

jade glacier Jul 31, 2020, 6:36 PM

#

This was all about regular state transfer based servers, which is the world Mirror lives in.

gleaming prawn Jul 31, 2020, 6:36 PM

#

Quantum IS an ECS

#

A production-ready one

jade glacier Jul 31, 2020, 6:36 PM

#

its a fixed point engine @weak plinth

gleaming prawn Jul 31, 2020, 6:36 PM

#

Quantum's SDK 2.0 is a sparse-set ECS (like C++ enTT)

jade glacier Jul 31, 2020, 6:37 PM

#

The concept of Quantum is full determinism, which makes it not comparable in most ways to discussions about state transfer only engines like Mirror and Pun2

But photon servers @jade glacier , which run the input management and clock sync (optionally simulation) in quantum, uses IO-completion ports (not traditional socket-threads)

jade glacier Jul 31, 2020, 6:38 PM

#

That just flew right out of my pay grade 🙂

grizzled narwhal Jul 31, 2020, 6:39 PM

#

I think I preffer the flexibility of mlapi

jade glacier Jul 31, 2020, 6:39 PM

#

They will get you the same perks and headaches @grizzled narwhal

grizzled narwhal Jul 31, 2020, 6:39 PM

#

Mh?

jade glacier Jul 31, 2020, 6:40 PM

#

Mirror and MLAPI give you NetEntities with IDs, and ways to wrap messages up with RPCs and Syncvars - but they do not tie into your simulation or simulation timings. So you are pretty much on your own with the sync timing and such.

#

MLAPI is a bit cleaner, because twoten started from scratch, but its also missing some luxuries... like the weaver in Unet was one of its real perks.

gleaming prawn Jul 31, 2020, 6:41 PM

#

hmmm

jade glacier Jul 31, 2020, 6:41 PM

#

But its all time based, and will give you fits in the long run if you don't get some kind of tick manager of your own in place and tie your messaging to your simulation

grizzled narwhal Jul 31, 2020, 6:42 PM

#

You mean mlapi's networktime isnt all that great?

gleaming prawn Jul 31, 2020, 6:42 PM

#

ye, neither MLAPI nor UNET nor MIrror have a great timing mechanism build in

jade glacier Jul 31, 2020, 6:42 PM

#

Networking with time rather than ticks is usually accompanied by mixing messaging with simulation... which is a no no

grizzled narwhal Jul 31, 2020, 6:42 PM

#

For the moment I havent bothered with input prediction/resimulation but thats probably an important step

weak plinth Jul 31, 2020, 6:43 PM

#

I have recently been enjoying UE's networking. I hope whatever unity comes up with to replace UNET is as extensive

jade glacier Jul 31, 2020, 6:43 PM

#

Messaging <-> State and Input Buffers <-> Simulation is typically how you keep state transfer sane.

gleaming prawn Jul 31, 2020, 6:43 PM

#

I wouldn't wait for Unity's default solution

jade glacier Jul 31, 2020, 6:43 PM

#

MLAPI and Mirror both encourage new users to tie messaging directly to Simulation... or WORSE to interpolation.

gleaming prawn Jul 31, 2020, 6:43 PM

#

They are on their 4th attempt, and counting...

grizzled narwhal Jul 31, 2020, 6:44 PM

#

I have messaging tied into simulation probably lmao

gleaming prawn Jul 31, 2020, 6:44 PM

#

UE is ok for the typical action/FPS use cases...

weak plinth Jul 31, 2020, 6:44 PM

#

was their network code before unet bad? I've never heard anyone complain about it and it seems like the only reason they got rid of it was Raknet which I don't really get

jade glacier Jul 31, 2020, 6:44 PM

#

All new networking devs do... its the first big mistake we all make when we first try this stuff. @grizzled narwhal

gleaming prawn Jul 31, 2020, 6:44 PM

#

Although they had a super super bad method for scoping (which gave them a LOT of headaches on Fortnite, and for PUBG)

jade glacier Jul 31, 2020, 6:44 PM

#

Networking is about simulation, not about messaging.

gleaming prawn Jul 31, 2020, 6:44 PM

#

Then they cam with the network graph "hack"

grizzled narwhal Jul 31, 2020, 6:45 PM

#

Networking is about simulation, not about messaging.
@jade glacier Could you elaborate?

gleaming prawn Jul 31, 2020, 6:45 PM

#

@weak plinth

was their network code before unet bad?
It was so bad that it's the main reason why all the alternatives had a chance

jade glacier Jul 31, 2020, 6:45 PM

#

Not as much as you probably would like, its a 5 hour lecture on time in gaming

gleaming prawn Jul 31, 2020, 6:45 PM

#

Unity's original UN (similar in concepts to PUN) just would not work outside of LAN

weak plinth Jul 31, 2020, 6:45 PM

#

yea my (limited) experience with UE networking so far is a generic third person which I assume is the perfect fit given Epic

gleaming prawn Jul 31, 2020, 6:46 PM

#

it was a full broadcasts P2P solution, pretty bad

grizzled narwhal Jul 31, 2020, 6:46 PM

#

The basic is probably to have the game code to be as networking unaware as possible no?

gleaming prawn Jul 31, 2020, 6:46 PM

#

UE networking has a few very good things in it... proper timing, a lot of stuff like Bolt, etc...

#

The major issue I saw was the lack of an efficient scoping mechanism for network culling on the server (performance on server for high player count was pretty bad, really bad)

jade glacier Jul 31, 2020, 6:47 PM

#

The model to think of for networking is the model for PhysX in Unity. There are two timings.. FixedUpdate is the PreSimulate callback, this is where actual simulation logic goes. All things in a game should be done on a fixed timing like that. Networking should be tied to that timing, not to Update().

Update is just for interpolation and extrapolation based on timeDelta.

#

FixedUpdate is the slideshow of reality that you don't actually see.

#

Update is where that slideshow is made pretty for the player

weak plinth Jul 31, 2020, 6:48 PM

#

there's also the SpatialOS integration but I haven't gotten that far yet

gleaming prawn Jul 31, 2020, 6:48 PM

#

Then they (Epic) developed the network Graph thing to deal with that (culling performance on server)... It's basic implementation is a damm GRID, but works

jade glacier Jul 31, 2020, 6:48 PM

#

Networking likes the slideshow... it should not know about or touch the smoothing of Update

gleaming prawn Jul 31, 2020, 6:48 PM

#

there's also the SpatialOS integration but I haven't gotten that far yet
I have a friend working there... But my expectations are of: you pay 10x more to deal with the overhead... lol

weak plinth Jul 31, 2020, 6:49 PM

#

I don't know anything about them besides that Worlds Adrift used it

jade glacier Jul 31, 2020, 6:49 PM

#

I haven't seen any clear demos of their tech that felt compelling

gleaming prawn Jul 31, 2020, 6:49 PM

#

It's interesting from the technical perspective (lots of neat stuff done by smart guys)

#

Worlds Adrift used it
Doesn't count, as it's backed by them AFAIK.

weak plinth Jul 31, 2020, 6:50 PM

#

compiling their (fork?) of the engine instead of dropping a library in did catch me off guard

gleaming prawn Jul 31, 2020, 6:50 PM

#

But... Lets see... THat's just my impression...:)

jade glacier Jul 31, 2020, 6:50 PM

#

Complexity doesn't make something a great utility unfortunately. But it might be great - it just didn't resonate with me in any demos or explanations as something I cared about or though was the right answer for most people's networking problems.

#

I work for the company that makes Quantum, but Quantum actually will eventually invalidate all of my work - so I am not biased to promote it.... but Quantum is the kind of innovation networking needs imo.

gleaming prawn Jul 31, 2020, 6:51 PM

#

I liked when I got a full explanation from one of their engineers (from the technical perspective)

#

But I did not had the chance to ask: how much would it cost for 10000 CCU?

jade glacier Jul 31, 2020, 6:51 PM

#

People making wild stacks of stuff to reproduce existing models without as much coding doesn't excite me.

#

(though I literally make that kind of stuff myself for a living)

gleaming prawn Jul 31, 2020, 6:52 PM

#

As a quantum core developer: I "envy" the technical challenges the guys of SpacialOS face...

#

lol

#

different types of challenges...

jade glacier Jul 31, 2020, 6:53 PM

#

Does it all come around to being a complete stack of stuff? @gleaming prawn Like do they have a toolkit for Unity that contains all of the drop in components for syncing up player states, anims, transforms, etc?

gleaming prawn Jul 31, 2020, 6:53 PM

#

My doubts are about the business model, technically it's cool stuff IMHO.

clever silo Jul 31, 2020, 6:54 PM

#

I work for the SpatialOS people, by the way. I don't work on SpatialOS itself, however.

gleaming prawn Jul 31, 2020, 6:54 PM

#

I have not followed since a long time, but ye, it would do scoped/culling properly, sync thousands of entities across super big worlds over the clients, scale the world simulation with clustering, etc

jade glacier Jul 31, 2020, 6:54 PM

#

The issue I see with a lot of those models is they kind of focus on a certain game type that they draw from... but offer very little for some actual new game types like RocketLeague - but i could be TOTALLY wrong.

gleaming prawn Jul 31, 2020, 6:54 PM

#

I have a friend there @clever silo

clever silo Jul 31, 2020, 6:55 PM

#

Cool. We're a big company these days

gleaming prawn Jul 31, 2020, 6:55 PM

#

ye, you guys got a lot of funding

#

Not sure if that will translate into profit..:)

jade glacier Jul 31, 2020, 6:56 PM

#

funding and profit are definitely different worlds in tech 🙂

gleaming prawn Jul 31, 2020, 6:56 PM

#

Emotitron, the SpacialOS premise is not "wrong" in itself, there's a case for MMO

jade glacier Jul 31, 2020, 6:56 PM

#

MMO is also not going anywhere

gleaming prawn Jul 31, 2020, 6:56 PM

#

It will just not be good for the stuff we solve well, for example

#

MMO is also not going anywhere
I'm not sure

jade glacier Jul 31, 2020, 6:57 PM

#

It does seem like most games just opt to not doing a massive world like WoW, and just put everyone into smaller groups

clever silo Jul 31, 2020, 6:57 PM

#

Definitely true to say that SpatialOS isn't a one-size-fits-all solution. I think any game networking expert will tell you that. Same goes for the UE4 model, etc

gleaming prawn Jul 31, 2020, 6:57 PM

#

Now that's really TALKING something cool... I'll drop my opinion (I don' t care if you care, lol)

clever silo Jul 31, 2020, 6:57 PM

#

WoW is actually a pretty badly-networked game - they just cover it up well

gleaming prawn Jul 31, 2020, 6:57 PM

#

yep.-..

#

here's my take on the trends...

#

SO far, we've had these techs that try to solve different worlds (coming from different perspectives - I'll mention only 2, but you guys will get the idea):

quantum starts from small-mid sized games (2, up to 64 players per match), UE struggles to run 100, etc, Apex runs 60, etc
SPacialOS (and WoW poorly) come from the other end, MMO sizes...

#

ANd the gameplay PACING is totally different...

#

You cannot have 3k players interacting ACCURATELY at 60Hz, it's impractical...
So MMO tech is slow and scales
Accurate and fast tech can only deal with smaller numbers

#

What I THINK we'll see in a few tittles in the next few years, maybe (IF they became successful enough) is getting to the MIDDLE:

#

a fast/accurate game (like small scale netcode) with 200+ players...:)

#

This is certainly MY GOAL... lol

#

Lets see what will actually happen

clever silo Jul 31, 2020, 7:02 PM

#

It's very hard to do, because the fast/accurate stuff tends to require predict/rewind/replay semantics, which carries a very heavy physics cost, and one that grows for every physics object you control locally

gleaming prawn Jul 31, 2020, 7:02 PM

#

🙂

clever silo Jul 31, 2020, 7:03 PM

#

Whereas MMOs don't attempt to do any of that, so they rarely need any physics interaction

gleaming prawn Jul 31, 2020, 7:03 PM

#

Wait and see then...:)

clever silo Jul 31, 2020, 7:03 PM

#

Good luck 😄

gleaming prawn Jul 31, 2020, 7:03 PM

#

Ye, I mean... We know we can already do

#

And we know what we can technically do (not with pure determinism, BTW)... For me it's more a question of being a good approach business wise

#

YOu need to have a market for fast-paced games with 200+ players

#

Nobody even knows if such market exists...

#

You can't consider Unicorns the norm...

weak plinth Jul 31, 2020, 7:05 PM

#

which came first, the chicken or the egg

gleaming prawn Jul 31, 2020, 7:05 PM

#

ye

clever silo Jul 31, 2020, 7:06 PM

#

Oh, there's totally a market. It's just tricky to do technically, hence why it's not already been solved by people who already know the FPS-style model well, like iD and Epic

gleaming prawn Jul 31, 2020, 7:06 PM

#

It's just tricky to do technically
It's tricky to do efficiently enough to make it feasible in terms of business model...:)

#

Specially with the current state of affairs with F2P etc

jade glacier Jul 31, 2020, 7:07 PM

#

I suspect most companies will just avoid trying to make a 1000 person battle royale.

clever silo Jul 31, 2020, 7:07 PM

#

Well, sure - it's already solved if you're happy to only run 1 physics step per second 😄

gleaming prawn Jul 31, 2020, 7:07 PM

#

No Kylotan

jade glacier Jul 31, 2020, 7:07 PM

#

The lanes that work are pretty well defined now, and companies can choose the game type they are making and stick to the limitations of that type.

gleaming prawn Jul 31, 2020, 7:07 PM

#

Not sure what exactly you work with, but I've seen interesting tests...

#

I think fholm mentioned here

#

10k players full KCC movement in <2ms on a single 16-core machine...

jade glacier Jul 31, 2020, 7:09 PM

#

the big wall fholm slammed into was in the priority engine

clever silo Jul 31, 2020, 7:09 PM

#

What is 'KCC'?

gleaming prawn Jul 31, 2020, 7:09 PM

#

kinematic character controller

#

the big wall fholm slammed into was in the priority engine
we solved the culling... can't say much though

clever silo Jul 31, 2020, 7:11 PM

#

I don't think any physics engine is capable of rewind and replay of 10K objects in a single step. So, either he's solved physics (which would be great beyond networking) or there is some other corner being cut

jade glacier Jul 31, 2020, 7:11 PM

#

not for quantum, this was for his MMO BR experiments @gleaming prawn

gleaming prawn Jul 31, 2020, 7:11 PM

#

A 200 or 500 player game is absolutely feasible...

#

I don't think any physics engine is capable of rewind and replay of 10K objects in a single step.
You don't, not for 10k

#

And yes @clever silo we write our own physics engines.

clever silo Jul 31, 2020, 7:11 PM

#

I've worked on games where we had 800 concurrent players on one server, one world. That in itself is not so hard. The hard part is trying to do that and to have a simulation with FPS levels of consistency

gleaming prawn Jul 31, 2020, 7:12 PM

#

That's correct

#

And with enough efficiency to pay for the server bill

#

To that regard, a game with 100 players is a lot more efficient than with 6 (considering you run dedicated servers per match/game)

#

But that if you solve culling/Scoping/priority-scheduled-updates efficiently...

#

800 with full server authority @clever silo ? and what specs?

#

I heard Epic runs an avg of 250 ccu per 4-core machine...

clever silo Jul 31, 2020, 7:16 PM

#

Sure, if you do enough area-of-interest stuff you can reduce the physics simulation area down to that similar to an FPS, which is manageable. Then the problem becomes trying to do that at a fast enough network tick rate, because MMOs usually have to send 2 to 5 times less frequently than shooters do

gleaming prawn Jul 31, 2020, 7:16 PM

#

y

#

the tick rate for network is typically 10-15hz

clever silo Jul 31, 2020, 7:16 PM

#

We had 800 on our servers back in 2008. Full server authority. But it wasn't doing physics, or rollback, or any of that stuff. Just standard MMO tech

gleaming prawn Jul 31, 2020, 7:17 PM

#

got it

#

I can't say much about our numbers unfortunately (on server, but >> 800).

#

Maybe I'll ask the Albion online guys, who run an MMO on photon servers

#

full server authority as well

#

It's not anything magic, you just use what you can... 800 in 2008 with full authority was probably correct/efficient

weak plinth Jul 31, 2020, 7:25 PM

#

So, I am using Mirror and Im a little blocked. I dont know if anyone here knows about this, but how can I spawn different prefabs in the local and server? In the local it should be a first person prefab, and in the server it should see a full body prefab.

jade glacier Jul 31, 2020, 7:33 PM

#

you should for simplicity sake make it one, and hide/show children based on hasAuthority or isLocalPlayer

weak plinth Jul 31, 2020, 7:34 PM

#

So the GameObject should have both? The FirstPerson and what the others user see?

spring crane Jul 31, 2020, 7:40 PM

#

Yea I feel like it would be convenient to have separate server and client models

weak plinth Jul 31, 2020, 7:46 PM

#

I was trying [Command] private void CmdSpawnPlayerController() { Instantiate(pf_net_localPlayerController); NetworkServer.Spawn(pf_net_netPlayerController); }
But i get GameObject pf_net_netPlayerController is a prefab, it can't be spawned. This will cause errors in builds. Both of the prefabs are registered

floral turtle Jul 31, 2020, 8:06 PM

#

@jade glacier is there any public info on perf with quantum? We don't want to rewrite our logic code for our project, but the core idea fantastic and really want to see how it pans out. I'm curious how well the rollback holds up with lots of physics objects...stuff like GGPO is obvs designed for smaller scale games

#

I saw a couple games with physics on the showcases, but nothing with tons of stuff (unless I missed it)

gleaming prawn Jul 31, 2020, 8:21 PM

#

GGPO does not implement anything

#

But first:

thousands of stuff (like RTS) you would NOT use rollbacks... YOu would run quantum in lockstep mode

#

we do what we call prediction culling (only predict/rollback what is closer to camera), running most of the world in "lockstep" with confirmed inputs from the steady server input stream... But still

#

I can say the numbers for Battlelands Royale

#

512 raycasts, 400 kinematic bodies, 32 players, 4000 static colliders, etc

#

per frame

#

30Hz, mobile

floral turtle Jul 31, 2020, 8:47 PM

#

ahh okay, yea something like prediction culling is what I was thinking. That's really cool @gleaming prawn

#

and yea ggpo ofc doesn't implement physics, but rather the games I know of it being mostly used on are smaller scale (fighting etc)

gleaming prawn Jul 31, 2020, 9:05 PM

#

ye, GGPO also does not have ANY concept of clock sync + input batcjing for 2+ players

#

is really just for 1v1

#

Quantum has currently a hard cap at 64 players, and has been battle tested with 32 in several mobile games (battlelands royale being one of them)
