Looking at https://doc.photonengine.com/en-us/pun/v1/demos-and-tutorials/package-demos/rpg-movement, it seems to have clients determine speed using last position and current position. Perhaps that's the suggested way.
On my player movement, my speed is calculated based on input and how far I tell the controller to move, so it will be a bit different, but perhaps I can make it work

Hello

#

I have a question regarding how to get into the server side part of game dev and MMO server Programming

#

I want to know how to get started I know C# did some basic servers and clients but this is actually my passion is the networking part of things my question is do I have to be good at game Programming in order to program the server ? Because I think most game Programming stuff will be in the client !

#

how to get and study the networking part / backend in MMO Programming

Do you have to be good at programming to build an mmo server? Yes, its actually the most difficult.

You say you know c# and have set up basic servers- but I'm guessing not a game server?
Your game programming will actually need to be sent to the server if you want any of it to synced to other players.. Which is more than hitting a switch.
So it's a lot of work, if you're not familiar.
If you are familiar- its still an mmo..

Handling massive amounts of players is not an easy task, no discord response could answer this properly in a way you'd learn properly so I would say research it.. Plenty on google

Where to get started? Write ups, books, Youtube, google, learning some simple structures by looking at some template assets would be my suggestions.

+dont make your first game, let alone first multiplayer game, an mmo.

ok i have an interesting networking problem. so i have an enemy script that targets a specific player using a nav agent. now im not 100% sure how i should go about networking it. should i have the person that the enemy is targeting do all of the position calculations and have all other users just update the position given by the targeted user or should i have each separate client calculate the enemy's nav mesh and just network the target
or the third option is have the host do all of the calculations
the first option would be fine except if the first user has bad internet and all the enemy's tracking him would lag with the user. the second option would cause sync problems where the enemy's are on different spots per client if there was any problems. and the third option relys on the host having good internet and i think is a generally bad idea

#

were still in the early stages of networking and i want to get a good framework down that we can use across the board

#

this isn't going to be a competitive game its going to be coop and were not going to worry about hacking or anything like that for the time being

#

this is probably one of those big problems you have to solve early on. like should we use a host client system strictly or a p2p type system

white stone Dec 26, 2020, 6:23 PM

#

Personally i would choose P2P, so who ever is the host of the session is like the server. Really comes down to the type of game it is.

@safe lynx and @prime dawn photon always had the enterprise offerings to let you write server side code over dedicated servers (it’s a photon specific api, called photon server plug-ins)

#

This has nothing to do with hosting a unity instance as a server, for example.

This was not added, this has been there since a long long time.

Hi, i have a problem with mirror.
I have to players (with the authority set to the client) and they both have a health script. There health variable is synced across all clients and the server. I also have a weapon script on the player which calls a function on the other player which takes some of its health away. This works fine for the player that connects to the host, but if i want to damage the other player as the host it doesnt work and i get this error message.

I dont get why this is working for one client but not for the host because its the same code running for both players

hi, im trying to make a multiplayer demo with a dedicated server. ive set up two seperate unity projects, one for the server and one for the client. i can send messages between server and client, however, im not sure how to get the connectionId of the client. the client connects to the server through this function in the client.cs script that is attached to an empty gameobject in the scene:

void Connect()
    {
        NetworkClient _client = new NetworkClient();
        RegisterHandlers();
        _client.Connect("localhost", 7777);
        Debug.Log(_client.connection.connectionId);
    }

the last line causes an error saying NullReferenceException: Object reference not set to an instance of an object
does the first line not create _client as an instance? how can i get the connectionId of the client connected? im lost and any help/advice is greatly appreciated :d thank you!

grim violet Dec 28, 2020, 2:51 AM

#

is connectionId something assigned once connected?

neon willow Dec 28, 2020, 2:55 AM

#

yea i think its automatically assigned https://docs.unity3d.com/2018.1/Documentation/ScriptReference/Networking.NetworkConnection-connectionId.html

#

it has to be smt in the form of like Instance.NetworkConnection.connectionId but im not sure if im creating client instance correctly or at all or idk

grim violet Dec 28, 2020, 3:01 AM

#

so you have to wait its connected before trying to get that variable

#

when you do client.connect its not instant

#

it gotta go trought connection and allow it and return an id somehow, while your code continue to run meanwhile

#

just dont debug there

#

for that variable

Hey, I'm trying to figure out best way to make my new multiplayer game.
I want players to be able to host the game themselves as well as make dedicated servers.
Dedicated server will be made in Unity anyways because I need to do some server side simulation.
So I'm thinking if it's possible to put that scene I make for dedicated server in the client as well and when someone hosts the game would it be possible to run 2 scenes at the same time?
Like does unity allow me to run one scene in the background while player is playing on another one?
Working with one scene that I could use in both cases would be best solution for me as solo game developer.

When I disconnect from Photon and after that I want to join a room again I get this error: MissingReferenceException: The object of type 'RoomManager' has been destroyed but you are still trying to access it.if (CountdownTimer <= 0) { if(RoomManager.Instance.gameObject != null) { Destroy(RoomManager.Instance.gameObject); } StartCoroutine("DisconnectAndLoad"); } That's where the error is.

tawdry pike Dec 28, 2020, 2:26 PM

#

@worldly plinth if you would create a server process that will handle the game state, you could also start this process locally when you want to let the 'user' create a game right? It should not matter if a client runs the server or if you run this in a data center (as long as the other players get access to this server). The latency will just be better for the player hosting the server 🙂

#

@lyric herald is the RoomManager as singleton (I am not familiar with Proton)? Do you have access to the object in the Coroutine (new thread?)

Hi, new here. I'm working on my first game, 2 player, 2d board game. Chose Unity mostly for platform coverage. I've got single board mode petty much done, so netcode is the next thing. After a bit of research, favoring PUN due to simplicity and humble requirements. Mirror would be my second choice. Question about PUN: Will PUN satisfy needs around user management? E.g. user account persistence, rating system, etc.

Installed PUN. I created my NetworkManager class, derived from MonoBehaviourPunCallbacks, but vscode can't see that class, or anything in the Proton.Pun namespace. My app runs, so it's not a typo in my code, and vscode finds other unity content (such as MonoBehaviour from Photon.Pun).

@jade glacier now it's happening with Visual Studio too! But here's a clue: if I delete the sln file, the problem goes away (a new sln is generated when I open source code from Unity). So now it looks like Unity is corrupting the sln (or presumably the vscode project in the case of vscode).

#

I imagine the problem will come back, so I'll keep deleting the sln, and try to pay attention to possible triggers.

If it is just compressing the byte[] before it is sent, probably not the best way to go about dealing with network compression.

#

Typically you want to make use of delta compression and bitpacking if you are trying to manhandle data rates.

#

This does seem to delta between writes, so that depends on you doing NO custom serialization and just serializing all of your data uncompressed into your byte[], and then running this on it each send.

jade glacier Dec 31, 2020, 12:59 AM

#

With unreliable connections, it will also need to keep a history to delta against. Because if the last delta didn't get through it needs to know, or it will be producing garbage.

It is free, so you can certainly download it and play with the API. You might be able to make use of parts of it.

what type of network solution would one prefer if they didn't necessarily want a "multiplayer game," but an idle game where logic is controlled by the server to prevent cheating

#

would also need to store information in a database, such as gold, but that wouldn't need to be related to the server. The server would need to communicate with the database to update it though. ie if the player spends gold to roll a random item, the roll would be done on the server, which would update the database

You are more than likely wanting to simulate it on the server and stream it to the client. Granted it is an idle game, and most don't really care that much. Honestly, wouldn't try and make it so you couldn't cheat unless there are actual in game stacks to someone else cheating. If it ruins just that one persons experience, honestly it is fine. Just make sure that you do a few checks on the server and it should be all good.

PUN2 is one of the easiest high level networking solutions. Mirror(very similar to UNet) would be a second one with a strong community. The major difference between the two is that PUN2 is peer to peer over relay, while Mirror is the more classic client - server setup.
Worth mentioning that MLAPI is now part of Unity, but there are some revamps in the horizon and the userbase has been a lot smaller from what I've seen.

#

You should be very comfortable with the basics of C# and Unity game development before throwing networking into the mix.

you can put anti-cheat on the same node as the server who propagates it

Hello everyone I'm new to Unity and programming.
I have tried following a tutorial on youtube about making a multiplayer game. I have arrived at a certain problem though.
When creating a "Plane" on the server side at 0,0,0 coords it's invisible so I created another "Plane" on the Client side at 0,0,0 however they don't match. Somehow the Plane on the client side needs to be adjusted by 10 on the Z axis in order to match and something like -1 on the Y Axis.
Any help would be appreciated 🙂

#

Left side is the Client and Right side is the Server

You should probably mention which networking Library. And whichever library you are using, you should start with the tutorial that that library recommends. @vague solar

#

I have found the issue and fixed it. It was SO simple this is so frustrating.
Regardless thanks for the help 🙂

jade glacier Jan 3, 2021, 8:39 PM

#

So what was it?

#

If you posted that on the forum, can you kill that post too if it wasn't a Photon issue? @vague solar

vague solar Jan 3, 2021, 8:42 PM

#

jade glacier So what was it?

I did not make a post about it. The issue wasn't Photon but my own puny brain. I have maid an EmptyObject and called it World which I had all my GameObjects inside (Plane, Cubes, etc...) and I set that world for some reason (only god knows why) to be at Y axis -1 and Z axis 10 instead of just leaving it on 0 0 0

Hello I'm making a multiplayer game using unity now and in server section I use socket io and node js
the unity package that I use for socket io is https://github.com/fpanettieri/unity-socket.io-DEPRECATED
I had a problem getting for parsing json array
my json array structure is like 👇

and the code that I wrote for parsing ans showing that is like 👇

socket.On("lap", (E) =>
{

That was one of my concerns, how much the cost would be

#

I’m not sure yet what solution I’m looking for. So far the ones I’ve found (mirror, photon, etc) don’t look like they’re what I’m looking for.

#

I need online data storage in my game but not “matching” or “see all the players on the screen”

Ok gpg as in the encryption ?

Thanks mate, so main question is when im using mirror and running locally I have methods that are run by the client and methods run by the server.

Hey all, could use some general tips here. I'll keep it general.

I'm doing mostly client authoritative. I have an ability that a player can use. I have it implemented as a state machine, as the player goes through a windup, aiming, shooting, and completing. There's timings associated with these, like needing to wait for windup to finish, etc.

For networking this, I originally had each client (even remotes) going through all the states. They'd run all the behavior. The local player would have the input that drives things.

I'm thinking this is probably error prone though. Like if a player's input doesn't come in with the right time, then a remote could be trying to process their second action while the remote instance isn't ready, perhaps still in the windup state.

So I think what it comes down to is handling state machines with networking. I'm thinking perhaps the local player should have the state machine, and the remote players don't run any of the logic. They just transition to the next state when RPC'd, no questions asked, and trigger animations.

Am I on the right track there? Thanks for any help.

jade glacier Jan 4, 2021, 11:51 PM

#

Be sure to indicate which library you are using when asking questions in this channel - since it isn't specific to any one lib. @ember tulip

ember tulip Jan 5, 2021, 12:00 AM

#

Sure, this is for Photon PUN in my case, though I'm trying to think about it generically

#

To be specific about my current issue:

The player has a bow. Hold left click to aim, let go to shoot.
It goes through a short windup, and then is ready to shoot.
If the player lets go of left click during the windup, the 'shoot' action will be queued, so the shoot happens as soon as the windup is done.

Right now, the RPC's being sent are to start the windup, and to do the shoot. Then each remote does this same logic that the local does. So each remote won't allow the shoot until the windup is done.

It seems to work, but I just feel like it is maybe fragile. For example, queuing the shoot could be on just the local, and then once the shoot actually happens, it RPC's and all remotes just start the shooting, regardless of their own windup.

Perhaps I'm overthinking it. I don't know.

#

I kinda feel like writing all of the above helped me work through it and I have a path. I think I'll rework this a bit and have the local player contain the majority of the logic. Remotes will replicate that logic when it comes to animations and such, but won't enforce state transition requirements.

I went with PUN on a previous project because of its free 20 CCU tier, which was similar to UNET matchmaking tier. It worked great to test run it without having to fork up money. However Photon doesn’t have a built in LAN solution, so I’m forced to look at Mirror...which doesn’t come with a plan like PUN (understandable). Does anyone know of a good combination for Unity/Mirror and some compatible online matchmaking service that has a free tier to sandbox before committing?

I did some general research and found Azure’s PlayFab solution. Is that a good fit for what I’m looking, or are there better combinations?

somber drum Jan 5, 2021, 12:41 AM

#

GameSparks/Playfab were the goto a while back, one of them changed their indie tier and people grumbled, not sure though

#

Photon not having LAN is something I'd not heard of, I guess it makes sense out of the box being it goes through their cloud

I'm trying to make my Unity application able to send web requests to an external API of mine (which works with HttpWebRequests). This isn't a problem, but I'm also trying to send signals the other way (API->Unity), because I want people to be able to choose when to start a training from our online website.
An alternative would be to do requests ever x seconds to see if the API has had variables changed, but that's far from the most efficient solution.

if you want a two-way connection you can use a simple TCP protocol.
otherwise polling is a practical and efficient solution

Here is a client script, and for some reason, it can send messages properly, but cannot receive them

        u.Client.ConnectAsync("127.0.0.1", 9050);
        Byte[] sendBytes = Encoding.ASCII.GetBytes("Is anybody there?");
        u.SendAsync(sendBytes, sendBytes.Length);
        StartNetworking();

    }

    public async Task StartNetworking()
    {

        var receivedResults = await u.ReceiveAsync();
        Debug.Log(receivedResults.ToString());
        StartNetworking();

    }```

#

        StartNetworking();

    }

    public async Task StartNetworking()
    {

        var receivedResults = await u.ReceiveAsync();
        Byte[] sendBytes = Encoding.ASCII.GetBytes("Send 2 Client");
        u.SendAsync(sendBytes, sendBytes.Length, receivedResults.RemoteEndPoint);        
        StartNetworking();

    }

Here is the server script, it can receive messages just fine. Any clue as to why the client isn't working properly?

Hi all, does anyone here know if Mirror has an equivalent of Photon's "PhotonView.Owner" functionality? I'm trying to get usernames that players enter on the start screen to be visible above their heads to all players in the game. Having some trouble. Found a tutorial on YouTube that uses Photon to do it rather simply, but I'd rather not rebuild everything in Photon after all the work I've done with Mirror. This may be very simple, but I'm new to coding and having trouble sorting through Mirror's API so I'm pretty much stuck haha

spring crane Jan 8, 2021, 4:18 AM

#

@outer hinge networkIdentity.connectionToServer maybe?

#

On the client I'm not sure if you can get the connectionID of other identities. Things generally in Mirror operate with the assumption that the state comes from the server.

MLAPI was recently acquired to replace UNet, but my understanding is that there will be major changes to MLAPI. Thirdparty Exitgames, Mirror, Forge and the like are likely still the more stable high level networking options for now.

floral turtle Jan 8, 2021, 6:31 AM

#

spring crane You do have some potentially interesting stuff out of the box with deterministic...

note that while Unity Physics is advertised as deterministic, it's not currently deterministic cross platform (ios, android, etc), and you also need to ensure that your entire game loop is determ too

#

so it's not a ready to go system like Photon Quantum

spring crane Jan 8, 2021, 6:45 AM

#

Oh thanks for the info. Apparently Burst is breaking that determinism based on a few forum posts.

@outer hinge if you werent able to fix dm me and I gotcha bud

dense hedge Jan 8, 2021, 12:42 PM

#

Rather than breaking cross-platform determinism I would say more like Burst hasn't figured it out yet. Consistent floating-point math across different CPUs and compilers has never been a casually toggle-able option like Burst aims to have.

#

Photon Quantum uses fixed-point integer math to be globally deterministic.

versed yew Jan 8, 2021, 6:56 PM

so if im making a game that isnt cross platform i can just use the normal unity physics and itll still be deterministic, right?

floral turtle Jan 8, 2021, 6:56 PM

floral turtle Jan 8, 2021, 7:03 PM

#

DOTS is likely determ between them, since what breaks PhysX is probably SIMD. But you'd still need a deterministic game framework to manage object lifecycle/detect desyncs etc

you can google around a bit, but stuff like sphere-sphere and box-box collisions are pretty straightforward. There's also things like this: https://assetstore.unity.com/packages/templates/systems/ufe-2-pro-125472#description

#

That asset was not deterministic when I last had contact with them. Maybe they fully redeveloped it

#

For fighting game’s determinism is pretty much the standard

#

But using a physics engomemos not, you normally just need basic collision detection, that you can copy and paste from any open source engine

versed yew Jan 8, 2021, 7:46 PM

#

I've decided to just use the unity one but keep track of the collisions in my own time management thing and have stuff happen based on that

gleaming prawn Jan 8, 2021, 8:05 PM

#

Unity’s is not deterministic, you will get desyncs

#

I mean I assume you want to do it o line, with something like ggpo

#

If it’s for a local game, no problem

versed yew Jan 8, 2021, 8:11 PM

#

I think collision itself not being deterministic won't matter if all the movement is deterministic

floral turtle Jan 8, 2021, 8:13 PM

#

versed yew I think collision itself not being deterministic won't matter if all the movemen...

if you're doing it for online, where you send inputs only (not the state of objects), you'll get into an edge case where on one peer the collision is detected, and on another it is not (due to the very slightly divergence between the collision calculattions), resulting in the entire thing desyncing

Unity currently is working on two networking packages, the MLAPI that they acquired and NetCode, which is DOTS only

green reef Jan 8, 2021, 11:45 PM

#

A simple Network issue, I think:
I have these two functions, CmdForward and RpcForward, you can view them here(like 6 lines of code):
https://pastebin.com/qJCVmJ6A
(channel = 3) is set to Unreliable Sequenced

When I press W forward is set to 1 on the clients almost instantly, but when I release W which uses the exact same function to set forward to 0, there is a long delay before 0 is set. If I hold forward for around 2 or more seconds before releasing, then the release message is received instantly like the initial send.

Pastebin

code - Pastebin.com

Pastebin.com is the number one paste tool since 2002. Pastebin is a website where you can store text online for a set period of time.

green reef Jan 9, 2021, 12:05 AM

#

The delay is causing a big de-sync and is really hurting the game, I have correction in place that lerps, but the desync is so big that it causes a ton of sliding around anytime a direction is changed.

so what would be a good asset to use for multiplayer games where one person hosts the game and you enter a game code to join their server (max 4 players per server) but I want an easy to use asset.

white stone Jan 9, 2021, 12:34 AM

#

@marble viper Read the pinned docs for starters, read this entire thread, way to hard to pinpoint exactly one asset.

I often see people asking the same question and people are reluctant to come out and just say we use blah, it does this and this, costs this much, etc etc. People on here hold the networking close to themselves but will still provide guidance.

Guys can anybody help me improving my udp networking class and protocol for my 2D game?

#

i'm not completly satisfied with the results... i don't know if it is a protocol error or a game implementation error, but my character doesn't update smoothly ( like in 60 fps )

#

If anybody could have the time to help me, it would be amazing!

white stone Jan 9, 2021, 12:48 AM

#

Ive no idea, have you tried the unity forum as well

silent zinc Jan 9, 2021, 12:50 AM

#

I have this networking class...https://hatebin.com/wqcatjwmva

#

for the client

#

server is a python server

#

basically, in the game manager, i call the Client.RecvPacket() in a separate thread, the client should receive the status of the other clients ( containing the x, y position of the character ). The processing of the packet is done in another thread. Every client, send their status in another thread, if the previous status is different from the current one

#

But the opponent updates really slow, how should i treat every packet?

#

For now my packet as this structure: bytePacketID + BodyLength + Body

#

this is my Packet class : https://hatebin.com/feihrqdtrb

slow monolith Jan 9, 2021, 8:32 PM

#

@gleaming prawn Have you ever made your own clientside reconciliation for rigidbodies in unity?

#

I'm looking for someone to point me in the right direction

gleaming prawn Jan 9, 2021, 9:14 PM

#

Are you following fholms stream

#

?

#

He’s building something from scratch and will cover most of these topics

slow monolith Jan 9, 2021, 9:17 PM

#

No I am not

gleaming prawn Jan 9, 2021, 9:18 PM

#

Server reconciliation assumes you track time or ticks on both server and client

#

And on client you store an input buffer.

slow monolith Jan 9, 2021, 9:19 PM

#

Yep thats all do-able

gleaming prawn Jan 9, 2021, 9:19 PM

#

When client receives server data, snaps it and resimulate forward with the input buffer

slow monolith Jan 9, 2021, 9:19 PM

#

Re-simulate with physics.simulate?

gleaming prawn Jan 9, 2021, 9:19 PM

#

You do not interpolate simulation. You interpolate visuals

slow monolith Jan 9, 2021, 9:19 PM

#

What about all of the other rigidbodies moving in the scene?

gleaming prawn Jan 9, 2021, 9:19 PM

#

Unity physX is not good@for that

#

Other bodies you should normally make kinematic and do jot@predict

#

Just interpolate from server data

#

Your own object best is a character controller

#

Doing this with unity@rigidbody is not an issue with the reconciliation, but rather with the limitations of the physics engine

slow monolith Jan 9, 2021, 9:21 PM

#

so it would be way easier to use a character controller instead of rigidbody

#

for the character

gleaming prawn Jan 9, 2021, 9:21 PM

#

If you use a stateless@physics, it’s easier

#

Yes, that’s is one of the goals@of a kcc

slow monolith Jan 9, 2021, 9:22 PM

#

So with the character controller, I can re-simulate multiple movements per frame right

#

and catch up pretty easily?

#

the default character controller component, included in unity

#

I'm a huge unity noob

gleaming prawn Jan 9, 2021, 9:25 PM

#

Yes, you can. But the unity@one is quite heavy, be advised

slow monolith Jan 9, 2021, 9:25 PM

#

hmm alright

gleaming prawn Jan 9, 2021, 9:25 PM

#

There’s one called KcC that people say it’s better

slow monolith Jan 9, 2021, 9:25 PM

#

I was really set on making this with a dynamic rigidbody :/ that sucks

#

During reconciliation, couldn't I just call physics.simulate every "catch up" movement on the rigidbody

#

and do that a bunch per frame

#

and sleep the other rigidbodies

#

which dont need to be moved

gleaming prawn Jan 9, 2021, 9:26 PM

#

It’s too expensive to reset many tigidbodies in physx

#

Try it

slow monolith Jan 9, 2021, 9:27 PM

#

ok

gleaming prawn Jan 9, 2021, 9:27 PM

#

And remember, you need a tick system before any of that

#

Or at least proper timestamps

slow monolith Jan 9, 2021, 9:27 PM

#

alright

gleaming prawn Jan 9, 2021, 9:28 PM

#

You don’t add reconciliation, you build a system that has that built in

slow monolith Jan 9, 2021, 9:28 PM

#

What's the point of a kinematic rigidbody though? Isn't that just the same thing as transforming a regular object?

gleaming prawn Jan 9, 2021, 9:28 PM

#

No

#

A kcc works with a physics query normally

#

It is not inserted in the broadphase data as regular body

#

Depends on the engine. The kcc I wrote for quantum is just a query, so you can call as many times as you need, reset, etc

#

Although technically anything in quantum is reset all the time

slow monolith Jan 9, 2021, 9:29 PM

#

Still very confused. Could you give a quick example?

gleaming prawn Jan 9, 2021, 9:29 PM

#

But the kcc itself@would also be fine without determinism

#

Sorry, typing from phone

#

Putting kid to sleep

slow monolith Jan 9, 2021, 9:30 PM

#

alright

#

Also I'm going to have cars in my scene, for which I will need dynamic rigidbodies with reconciliation

#

right?

gleaming prawn Jan 9, 2021, 9:34 PM

#

Normally yes

#

Cars is a complicated topic

#

The easiest way to do car racing that I know of is the quantum approach

#

But what you can do is to extrapolate the other cars manually as kinematics

slow monolith Jan 9, 2021, 9:35 PM

#

So you're telling me I'm going to need something like photon in the end?

gleaming prawn Jan 9, 2021, 9:35 PM

#

You get the server data including player input and velocities

#

Compute a prediction based on that. Interpolate the visuals just slightly

#

No no... you can do like I just said without quantum

slow monolith Jan 9, 2021, 9:36 PM

#

alright

gleaming prawn Jan 9, 2021, 9:36 PM

#

But you are on your own to do it

#

With quantum it’s just a lot easier

slow monolith Jan 9, 2021, 9:36 PM

#

Can all of this prediction computing be on the same scene

#

as the actual game

#

And I'm guessing you're just talking about running physics.simulate a bunch of times in a single frame?

gleaming prawn Jan 9, 2021, 9:37 PM

#

Just for yours

#

I’m sorry, but you need to have the basics understood first

#

If you have a tick based system, input and data from server with all that, you can just extrapolate a kinematic

#

No need to step the physics engine for all cars

#

Only for yours

slow monolith Jan 9, 2021, 9:38 PM

#

alright

#

Yeah I think im just gonna use photon haha

#

sounds like the best solution imo

#

Do AAA games use photon?

#

Like rust and tarkov and such?

gleaming prawn Jan 9, 2021, 9:41 PM

#

Photon has several products

#

For what you are trying to do best is quantum which is not for free

#

Or the new fusion which will be released in a few months

slow monolith Jan 9, 2021, 9:43 PM

#

ok

#

By stepping the physics engine for the car, you mean the car that the client is currently sitting in and controlling

#

only step his car?

#

and just extrapolate the others that hes not driving

gleaming prawn Jan 9, 2021, 9:52 PM

#

Yes, exactly

slow monolith Jan 9, 2021, 9:53 PM

#

alright

#

But If I'm snapping the car back and then running physics.simulate multiple times per frame

#

won't the client see all of that happening?

#

or is it too fast?

#

My other solution would be to have a ghost rigidbody following it, and the ghost rigidbody does all of the physics simulations

#

and then hands the final position value to the actual rigidbody

gleaming prawn Jan 9, 2021, 9:57 PM

#

You step multiple times in one single update

#

Player only sees the final result

#

You also need to interpolate the visuals

slow monolith Jan 9, 2021, 9:57 PM

#

And then I would just sleep the other cars that were moving

gleaming prawn Jan 9, 2021, 9:57 PM

#

I really suggest you watch fholm streams

slow monolith Jan 9, 2021, 9:57 PM

#

until the simulation is done?

gleaming prawn Jan 9, 2021, 9:58 PM

#

There are several topics you are mixing which are required to work together

slow monolith Jan 9, 2021, 9:58 PM

#

alright ill have a look. thanks

slow monolith Jan 9, 2021, 11:17 PM

#

I watched a couple tutorials and I understand the ticks and stuff, the only thing im stuck on is actually re-simulating movements on the clientside

#

if I sleep all of the other rigidbodies and then loop a bunch of physics simulations inside a single frame, with the goal to only move a single rigidbody, the rigidbodies that I sleeped are going to appear to be stopped for a split second, if they were already in motion, right?

#

since fixedupdate runs differently?

#

Or should I loop the physics.simulate events inside fixedupdate instead?

#

The only thing that seems logical would to do the calculations in another scene, with only the player rigidbody in it

slow monolith Jan 9, 2021, 11:47 PM

#

You don't know how much I would give to be able to simulate individual physics objects at a time

#

that would literally solve this problem

slow monolith Jan 10, 2021, 12:04 AM

#

I'm a bit of a moron, so you'll have to explain this as if you were talking to a 10 year old

floral turtle Jan 10, 2021, 12:29 AM

#

@slow monolith haven't followed the entire thing, but are you only trying to resimulate the character? You can do this if you make a custom character controller, or use something like this: https://assetstore.unity.com/packages/tools/physics/kinematic-character-controller-99131

Kinematic Character Controller | Physics | Unity Asset Store

Get the Kinematic Character Controller package from Philippe St-Amand and speed up your game development process. Find this & other Physics options on the Unity Asset Store.

#

also—is server authority necessary? Can be easier to just give clients authority of their char if you aren't worried about cheating

slow monolith Jan 10, 2021, 12:30 AM

#

Server auth is necessary, and I'll need to use dynamic rigidbodies because of the cars

#

someone suggested full rollback

floral turtle Jan 10, 2021, 12:30 AM

#

ahh it's cars, sorry I missed that

#

yea, I don't know any way to resimulate a single physics object beyond pulling it into a separate scene, but that would preclude colliding with other cars. Full rollback would allow that, but PhysX does not always play nice with rollback (certain behaviours become different when a scene has its state manually set)

slow monolith Jan 10, 2021, 12:31 AM

#

seems like the only option lmao

#

I'd like to know what the AAA titles on unity use

#

like rust and tarkov

#

both great multiplayer experiences

floral turtle Jan 10, 2021, 12:32 AM

#

not super familiar with either, do they have vehicles or mostly 3rd person character?

slow monolith Jan 10, 2021, 12:32 AM

#

Rust does

#

I think tarkov is planned to

#

Rust cars use prediction too

floral turtle Jan 10, 2021, 12:33 AM

#

rocket league is unreal, but it uses full rollback and prediction (bullet physics)

slow monolith Jan 10, 2021, 12:33 AM

#

sounds like im going with full rollback then

floral turtle Jan 10, 2021, 12:33 AM

#

rust uses raknet for the actual networking, not sure about the simulation layer

slow monolith Jan 10, 2021, 12:33 AM

#

hmmm

jade glacier Jan 10, 2021, 2:06 AM

#

You need resimulation for sure?

#

Games like RocketLeague go that route because they have a very specific case that makes interpolated states not an option.

#

I wouldn't get down the long deep rabbithole of making a system that tries to predict everything unless you really need it.

slow monolith Jan 10, 2021, 4:39 AM

#

I mean the player needs to be resimulated

#

because its authoritative with prediction

#

Is there a way that I can ONLY re-simulate the player and not fuck up the physics completely in my game?

#

because if I pause the physics, and call physics.simulate a couple times in a loop on update(), won't the player be able to see the physics stopping for a second?

jade glacier Jan 10, 2021, 4:45 AM

#

Nothing is paused. You don't resim in realtime.

#

You don't need to be deterministic for client prediction of you're game doesn't require 100% determinism. You can allow some tolerance for desync. Deterministic results make things a lot easier, but it isn't required for snapshot interpolation.

slow monolith Jan 10, 2021, 4:48 AM

#

So how would I apply the re-sync

#

once it needs to occurr

jade glacier Jan 10, 2021, 4:49 AM

#

You reset the state to what the server just said it was for that previous tick. And then quickly reapply all inputs and simulate back to current, like you are saying.

slow monolith Jan 10, 2021, 4:51 AM

#

re-apply all inputs using physics.simulate?

#

all in a single frame?

jade glacier Jan 10, 2021, 4:52 AM

#

The topic is more about a complete rollback with deterministic, vs just running a second simulation to resync some objects with the server.

#

You resimulate x ticks

slow monolith Jan 10, 2021, 4:54 AM

#

The only real physics objects I'm going to have are players and cars

#

not much else

jade glacier Jan 10, 2021, 4:54 AM

#

If you are in tick 20, and the server msg for tick 10 arrives, you compare the state of your predicted objects as they were on tick 10....

slow monolith Jan 10, 2021, 4:54 AM

#

correct

jade glacier Jan 10, 2021, 4:54 AM

#

You apply tick 10... And resim 10x

#

Depending on your game, that resim might only need a few objects involved.

#

Rather than a complete rollback of everything.

slow monolith Jan 10, 2021, 4:55 AM

#

well physics.simulate forces all rigidbodies to update

#

so how would I avoid resimming some objects

jade glacier Jan 10, 2021, 4:56 AM

#

You can run multiple physics scenes as needed

slow monolith Jan 10, 2021, 4:56 AM

#

alright

#

is that not slow?

jade glacier Jan 10, 2021, 4:56 AM

#

Not as slow as resimming an entire world of objects 10x

#

But again, the correct answer depends on your simulation and game architecture.

slow monolith Jan 10, 2021, 4:57 AM

#

alright

#

so if the only rigidbodies I have are the players and the cars, It would just be better to resim on the main scene itself?

jade glacier Jan 10, 2021, 4:57 AM

#

No idea

#

Depends on your game and what needs to be part of your desync correction

slow monolith Jan 10, 2021, 4:58 AM

#

ok

i was asking if im in singleplayer mode should i just have an if statement separating the two different types of instantiations, or should i just make an entire new script one for multiplayer one for single player so i wont have to constantly check if its online or not

quick folio is it hard to make the traffic like the one in GTA online ? all cars can be sync

I'm planning on making the same thing. All car positions need to be handled on the server

#

I don't think that's how GTA does it regardless. Considering if you're in a car with a friend and you run over an NPC, it most likely won't show up on his screen (positions generated by the client, non authoritative server)

#

hence why it's so easy to hack on GTA

#

I'm very curious as to why they build their game like this. Perhaps the map itself is just too giant to be handled by a server? Or maybe there's too many players and it would be a waste of money to waste that much computing power making authoritative server lobbies

hey im working on a self hosted MySQL server + php.

#

its up and working but i just want to make sure im not opening up my computer to bad stuff xD

#

i mean apart from the obvious and unpreventable like DOS attacks

slim ridge Jan 11, 2021, 9:15 PM

#

keep an eye on your bandwidth usage

safe lynx Jan 11, 2021, 9:25 PM

#

Fair enough is that it lol

#

I think I have my permissions setup right

#

Only accesses to the database from localhost are allowed

#

And the php scripts are obviously local host. So the only (hopefully) thing that’s public is those php scripts

#

And the php scripts have very strict rules on what it allows for input. And generally your not allowed to make changes to the database unless you have a token that’s generated when you login

#

And even if you have said token you’ll only be able to change the database that relates to your user account

#

Theoretically the worst thing someone can do is destroy their own user account

slow monolith Jan 11, 2021, 10:25 PM

nobody is going to waste resources ddosing a random webserver for fun. One of my friends however made his SQL server public with no password and it got ransomware'd in like under 2 minutes

#

so keep that in mind @safe lynx

safe lynx Jan 11, 2021, 10:29 PM

#

yea wdym making the server public Reeee

#

like if you go to the IP:85/phpmyadmin

#

it asks you for a username and password

#

ive made 4 accounts

#

anyone accessing from localhost has full access

#

anyone with my username and Password has full access

#

anyone with the other devs info has full access

#

and one last public account that only has SELECT access. (read-only)

#

so the people part of the playtest can see how everything works if they wanted to

#

but i dont understand how you could send get ransomware from that xD

#

but im planning on hosting it on a VM later anyways to stop anything bad from happening lmao

#

or host it on a spare computer

slow monolith Jan 11, 2021, 10:34 PM

#

Making it public = port forwarding your router

#

so outside clients can access your private server

#

If you leave your username and password as root, it will get hacked in under 2 minutes by scanners

safe lynx Jan 11, 2021, 10:34 PM

oh ive already port forwarded everything

If a client can write his own input, and that input gets shoved in an SQL query

#

and you don't sanitize it for bad characters

#

then you will get hacked

#

thats the basis of SQL injection

safe lynx Jan 11, 2021, 10:40 PM

alright here are two scripts. login and register user

#

<?php

//varaables submitted by user
$input = json_decode(file_get_contents('php://input'), true);

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
  die("Connection failed: " . $conn->connect_error);
}
$sql = "SELECT * FROM users WHERE username = '".$Username."'";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
  // output data of each row
  while($row = $result->fetch_assoc()) {
    if($row["password"] == $PasswordHash){
        echo $row["userID"];
    }
    else {
        echo 0;
    }
  }
} else {
  echo 0;
}

/*
if ( $option == 1 ) {
  $data = [ 'a', 'b', 'c' ];
  // will encode to JSON array: ["a","b","c"]
  // accessed as example in JavaScript like: result[1] (returns "b")
} else {
  $data = [ 'name' => 'God', 'age' => -1 ];
  // will encode to JSON object: {"name":"God","age":-1}  
  // accessed as example in JavaScript like: result.name or result['name'] (returns "God")
}
*/
header('Content-type: application/json');
//echo json_encode( $data );

$conn->close();

?>```

#

login given a username and a password returns the user ID of said user in the database

slow monolith Jan 11, 2021, 10:41 PM

yeah you're not sanitizing your inputs

thats gonna get you hacked

does some anti hacker stuff

Reeee

slow monolith Jan 11, 2021, 10:43 PM

#

If you allow raw strings in your SQL queries

#

without sanitizing them

#

people can run their own queries

#

such as drop all tables

#

and delete all your shit whenever they want

safe lynx Jan 11, 2021, 10:43 PM

#

yea i see now how that could ruin everything

#

theres probably a bunch of other stuff i should try like disallow spaces

slow monolith Jan 11, 2021, 10:44 PM

#

real escape string should do the trick

#

unless someone else has a different opinion

#

as long as you're not running dynamic javascript code from your database then you're fine

#

that's a whole other lesson

#

XSS injections

safe lynx Jan 11, 2021, 10:45 PM

#

Reeee

#

im eventually gonna try my hand at server side code but for now all the scripts are just going to be middle man scripts

#

oh also heres my register user script

#

<?php
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "CeaseVR";

//varaables submitted by user
$input = json_decode(file_get_contents('php://input'), true);
$Username = $input["Username"];
$PasswordHash = $input["PasswordHash"];

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
  die("Connection failed: " . $conn->connect_error);
}

$sql = "SELECT username FROM users WHERE username = '" . $Username . "'";
$result = $conn->query($sql);
$randomUserID = "0";
$returnStatement = "";
if ($result->num_rows > 0) {
    //tell user that name is already taken
    $returnStatement = "Username Taken";
} else {
  //Insert user in database
    $randomUserID = rand(0,999999999);
    $sql2 = "INSERT INTO users (userID,username, password, level, coins) 
    VALUES ($randomUserID,'" . $Username . "','" . $PasswordHash . "',1,100)";
    $sql3 = "INSERT INTO playercustomization (userID, nameColorR, nameColorG, nameColorB) 
    VALUES ( $randomUserID ,255,255,255)";
    if($conn->query($sql2)===true && $conn->query($sql3)===true ){
      $returnStatement = "User Registered";
    } else {
      $returnStatement = "Registered Failed";
    }
}
$data = [ 'status' => $returnStatement, 'userID' => $randomUserID];
header('Content-type: application/json');
echo json_encode( $data );
$conn->close();

?>

#

given a username and a password hash it creates a new user with a bunch of default user info

#

also i know to never store plain text passwords ever

#

thats another reason i wanted to make the database public readonly so people can see what information im actually storing

slow monolith Jan 11, 2021, 10:47 PM

You're not checking for random user ID collisions

#

not a huge problem

safe lynx Jan 11, 2021, 10:48 PM

yea its a very basic script so far xD

#

i was just gonna do big random numbers and hope they never overlap untill i spend a few hours making something else work lol

slow monolith Jan 11, 2021, 10:49 PM

#

PHP also has built-in password hashing functions

#

never use MD5 or anything like that

#

you can bruteforce it extremely quick and I've seen it done on databases in realtime

safe lynx Jan 11, 2021, 10:49 PM

#

ahh im doing the hashing at the client level

slow monolith Jan 11, 2021, 10:49 PM

that should always be done on the server

client only sends raw password

However

Let me propose another problem to you

i dont want to just make a windows VM cause it seems wastefull but i dont know what else to use

slow monolith Jan 11, 2021, 10:56 PM

#

User registers with any name he wants, makes his name <script>alert("HELLO WORLD");</script>

#

what happens when the client browser sees his name

#

client runs the code

#

thats dangerous because you can use javascript code like that, to grab the cookies of the client that the code is running on, and send it to a remote server that an attacker controls

#

now all of your clients have been hacked

first of all this is running in a untiy standalone .exe

slow monolith Jan 11, 2021, 10:57 PM

#

I have no clue

safe lynx Jan 11, 2021, 10:57 PM

#

but second im not really sure

#

i could do a max name length and dissalowed characters?

slow monolith Jan 11, 2021, 10:58 PM

#

you'll need to disallow characters like that AND sanitize the input with regex on the backend

#

because if someone bypasses your front-end filter, it's not gonna do much

#

I actually think php has a built-in function for that hang on

safe lynx Jan 11, 2021, 10:59 PM

#

deffinatly. also if you wondering im gonna lock down the register user script to require a single use token given when you buy the game

slow monolith Jan 11, 2021, 10:59 PM

#

htmlspecialchars($string);

#

If I recall correctly

#

this will print that, without making the javascript run

#

so whenever you post comments or display usernames or shit, make sure they're run with that

safe lynx Jan 11, 2021, 11:00 PM

i suppose but this is never gonna use a website to run the game xD

yeah then you only need to worry about sql injection

safe lynx Jan 11, 2021, 11:03 PM

and to fix that you do said sanatize functions with some basic sanity cheaks

#

like dont allow anything longer than 30 char

cause regardless of how safe it might be its still shady af xD

That usually means that the function "FlipFalse" is not on the same object your calling - for example, if your trying to do something like this:

public class Player : Mono
{
[PunRPC]
void SomeNetworkedFunc() { ... }
}

public class GameManager : Mono
{
void SomeFunc() {photonView.RPC("SomeNetworkedFunc", ...);}
}

In this case, "GameManager" is calling its local photonview, and not the one on "Player", and "SomeNetworkedFunc" doesnt exist on GameManager, so it cant find it - producing your error

I'm having trouble with ClientWebSocket, and this is really stumping me. It can connect to the server, and I see the connection/disconnection, but after connecting I get the following exception at a 1sec interval:

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

But, when I connect to the same websocket server using a browser, it connects and sends messages just fine.

Also, additional note: The same ClientWebSocket code, when changing to wss://echo.websocket.org has the same error as my custom websocket server, and again works fine in browser on the same machine.

small saddle Jan 12, 2021, 7:24 PM

#

fast stone <@!168578802421727232> one more, problem, run animation , looks nice and work ni...

Not sure what you mean? That could probably be the actual animation itself, I dont see why that would be "laggy" on the network, if anything it might be delayed before it plays (unless thats what you are referring to)

Also as a side note, you actualy could combine those 2 RPC's into one, and pass in a param, for example:

[PunRPC]
void Flip(bool isFacingRight)
{
sr.flipX = isFacingRight;
}

void SomeFuncThatCallsYourRPC()
{
howeverYourAccessingYourPhotonView.RPC("Flip", ..., true);
}

The third param is technically supposed to be a new object[] { whatever you need to send over the network } but if its only 1 param, it will automatically treat it as that anyway, so instead of "true" you can specify the condition that determines your flipX value - just reduces the number of messages your generating and cleans up your net code a little

I dont think thats your animations, that looks like the position itself, possibly the "teleport at distances larger than" value is set too high, or your PhotonNetwork.sendRate is too low if you modified it (and I would be careful about modifying the sendRate, as itll add more messages per min/more network traffic to your room)

small saddle Jan 12, 2021, 8:43 PM

amber trench is there a photon way to join a lobby with a shared code?

AFAIK not natively, but what I did is store the room code/password as a string in the rooms CustomProperties, retrieved it and then compared the players entered code from a input field to that rooms custom properties "password", if it matches connect them to the room, if not display an error

PHOTON

Alright so I got a problem with the OwnerShip of a room, whenever the owner does the action it works fine but for the other players, the script doesn't work and it applies to the owner.
Ex : When a player goes to another room, the Owner cannot see himself in the room, he sees the player that just entered in a new room.
I'll leave the script here.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

New to multiplayer in Unity. I have a NetworkManager set up with my player prefab attached. I have a NetworkIdentity on the root object of my player prefab and my player movement script is attached to said root object and I'm trying to use "isLocalPlayer" but it's giving me an error in the console

UnityEngine.Networking.NetworkBehaviour:get_isLocalPlayer()
PlayerMovement:Update() (at Assets/Reid's FPS Controller/PlayerMovement.cs:21)```
Not sure what I need to do
Don't know which object it's referring to
Oh and I also get this error in the console
```NullReferenceException: Object reference not set to an instance of an object

Hi guys, i have a networking question, what are the best approaches when dealing with a multiplayer game based on udp? I'll be more specific...i have this client method for receiving... ```cs
public static void RecvPacketSync()
{
try
{
if (client != null)
{
if (client.Client != null)
{
if (client.Client.Connected)
{
byte[] buffer = client.Receive(ref selfEndpoint);
if (buffer != null)
{
if (buffer.Length > 0)
{
ProcessBuffer(buffer);
}
}
}
}
}
}
catch (Exception e)
{ Debug.Log(e.ToString()); }
}

subtle gale Jan 13, 2021, 2:51 PM

#

Are there many opinions on using mirror vs photon vs forge?

#

For context, I'm mostly looking for something that supports networked physics

#

or at least allows for a low enough level of sending packets alongside the framework that I could implement snapshots myself

OK, so after trying out three different WebSocket implementations, I can't create a client app because I can't connect to any servers. I get the exception:

SocketException: No connection could be made because the target machine actively refused it.
Rethrow as WebException: Error: ConnectFailure (No connection could be made because the target machine actively refused it.

I don't have a firewall on my PC. There's no firewall rules setup on the router. I can't connect to local, localhost, or ws://echo.websocket.org.

BUT, using a browser and JS I can connect to all, without error

I'm stuck, and could really use some advice. I need to get my wheels out of this rut ASAP, because it's blocking my development

subtle gale Jan 13, 2021, 3:38 PM

#

@rare cliff which websocket libraries are you using? or do you have your own retry loop for connection?

rare cliff Jan 13, 2021, 3:39 PM

#

I've tried wrappers for .NET's WebSocket, two flavors specific to Unity, and websocket-sharp which has no external dependencies and is a custom implementation

#

I've used these before, years ago. I'm not sure why it's not working now

#

It connects, and I can see the Connect/Disconnect on the server. It just throws that error every second after initiating the connection

#

I also can't send/receive data correctly

subtle gale Jan 13, 2021, 3:43 PM

#

are you using windows?

#

or linux/macos

rare cliff Jan 13, 2021, 3:49 PM

#

@subtle gale Windows 10, Unity 2020.1.5f1

#

If I use the same websocket-sharp DLL in a standard .NET 4 Console project, I can connect, send/receive messages without issue

#

(same code too, just a copy and paste)

subtle gale Jan 13, 2021, 4:56 PM

#

are you building for the webplayer by chance? https://docs.unity3d.com/530/Documentation/Manual/SecuritySandbox.html

rare cliff Jan 13, 2021, 5:54 PM

#

Hm, so if I make an empty 2020.1.17f1 project, it works 🤔

#

Derp, it was a component that was failing an HTTP call on an interval, but just coincided with the time I implemented Websockets. The stacktrace didn't give me the root calling component, so I had assumed it was Websockets 😛

#

So, that wasted a whole day of my time because I couldn't access the whole calling stacktrace to see what originated the call

Is it better to do the parsing of a status packet in the Update() or in a separate thread?

subtle gale Jan 13, 2021, 6:19 PM

#

@rare cliff well at the very least it is a learning experience

rare cliff Jan 13, 2021, 6:19 PM

#

@silent zinc I generally try to queue things, and then handle them on the main thread. You can parse it, but only if it's never reading data outside the packet

#

So, I'll make a thread safe queue of things, and then go through that queue when the main thread loops around

silent zinc Jan 13, 2021, 6:21 PM

#

yes ok, but like, is it better in terms of perfomance?

rare cliff Jan 13, 2021, 6:21 PM

#

Dunno, but it's better in terms of data layout and async calls

silent zinc Jan 13, 2021, 6:21 PM

#

Parsing every packet and updating the character in the Update i mean

#

in game

rare cliff Jan 13, 2021, 6:21 PM

#

Likely more efficient, but you'll have to test on your specific use case

subtle gale Jan 13, 2021, 6:22 PM

#

I would assume it would just be more efficient based off caching

#

but profiling trumps all usually imo

Is Photon Quantum ever going to become more accessible to hobbyists?

gleaming prawn Jan 13, 2021, 8:40 PM

#

Maybe, maybe not... the new photon fusion will for sure

#

Quantum requires a lot more commitment as it is a multiplayer game engine where unity is a view/ui engine “only” (also used for level design). It’s not only the pricing but the fact that you need to really have a clear goal to finish a game, etc.
It’s a steeper learning curve that pays off if you have a game that maps clearly to the approach (deterministic predict rollback).

#

We’ve opened to revenue share deals and are still willing to discuss these options with special cases whenever it makes sense.

#

But as a general free tier to hobbyists to download and try its a bit more involved due to all I explained.

#

Feel free to send us an email if you have something in mind where it clearly is the best option.

subtle gale Jan 13, 2021, 8:45 PM

#

I see, is there much new information about fusion? Haven't really seen much about it past an email + a forum thread

gleaming prawn Jan 13, 2021, 8:46 PM

#

And as I said, the new Photon fusion that will replace both bolt and pun will have several tiers and options

#

Not yet, but we’re very close to start the alpha with some selected teams

#

I can’t say the exact date, but it’s very close

#

It’s this month still...:) for a public release I can’t share anything yet

#

But fholm has been streaming about networking (he pasted links here every day he streams) and he talks about it a lot

#

He’s the lead developer again (also quantum and bolt)

subtle gale Jan 13, 2021, 8:49 PM

Can anybody help me? It's related to the previous question, now my parsing code is done in Update(), the result seems pretty much improved, but still it is not the same as the playing character...what could i possibly doing wrong?

            }
        }
    }
    catch
    { }
}
``` these are two threads that handle the player status, and send it to server.

#

am i doing something wrong in the protocol?

#

what are the main cause of character not updating in 60 fps like the playing character? Like, it seems that the protocol is stable, looking at the debug logs of server/client.

#

But clearly something is taking too much time to process...

grim violet Jan 13, 2021, 9:25 PM

#

those are not threads, they are just method

#

protocol should be udp

#

not sure what cause your character to not update 60 fps i dont understand your question

silent zinc Jan 13, 2021, 9:26 PM

#

yes sorry they are the methods attached to the thread run

silent zinc Hi guys, i have a networking question, what are the best approaches when dealing...

☝️

grim violet Jan 13, 2021, 9:27 PM

#

are you waiting for the packet to be received before moving the player

silent zinc Jan 13, 2021, 9:27 PM

#

which player?

grim violet Jan 13, 2021, 9:27 PM

#

i dont know what you are doing

#

what packet are you sending and receiving? just a number?

silent zinc Jan 13, 2021, 9:29 PM

#

i'm sending a status class that has attributes of the player, floats and bools, and the packet has this structure : headerByte + BodyLength + Body

grim violet Jan 13, 2021, 9:29 PM

#

why do you say its not updating 60 fps ?

#

what isnt updating?

silent zinc Jan 13, 2021, 9:29 PM

#

the opponent

#

like it's in almost 30 fps

grim violet Jan 13, 2021, 9:30 PM

#

its updating when it receive data, but dont expect data to be sent 60 time a second and received the same way, there can be error, data lost, lag

#

how do you know its updating at 30 fps instead of 60

#

if you arent moving anything

silent zinc Jan 13, 2021, 9:31 PM

#

ok i'm doing this in game, i'm sending the status packet only if the status has changed, the server just send that packet without worrying about being received

#

I have a receive protocol, like another packet for telling the other side that it has been received

#

which i'm still testing

grim violet Jan 13, 2021, 9:33 PM

#

should always expect a delay

#

60 fps is 16.7ms second, i dont believe the ping itself is under 30ms

silent zinc Jan 13, 2021, 9:34 PM

#

on localhost???

grim violet Jan 13, 2021, 9:34 PM

#

well not local host no

silent zinc Jan 13, 2021, 9:34 PM

#

lol

grim violet Jan 13, 2021, 9:34 PM

#

there still some execution time and all

#

i dont nknow what is all behind it

silent zinc Jan 13, 2021, 9:35 PM

#

what do you need to know?

#

Could you help me please?

grim violet Jan 13, 2021, 9:36 PM

#

still trying to figure out what you trying to do lol, but no i probably cant help you
been a while i didnt play with socket directly, im using third party which have thought of all problems already ;p

#

one thing is sure you cant send a packet every frame

#

and exspect it to be received at same pace

silent zinc Jan 13, 2021, 9:38 PM

#

that's why i'm ignoring the previous packet, and sending the next right away when the status change

grim violet Jan 13, 2021, 9:38 PM

#

packets are not received in order in udp too

#

unless u mark them

#

like if you receive packet 48 then 46 you ignore 46

silent zinc Jan 13, 2021, 9:39 PM

#

i'm assign to every packet a ulong

#

that gets increased when the status change / sending the packet

#

so like even the server, store the previous status N and if the next packet has not N greater than previous, it will reject it, same in client side

silent zinc Jan 13, 2021, 9:43 PM

#

ehm no, cause i just have the characters, everything plays fine for now, but the character moves not smooth like the playable one.

grim violet Jan 13, 2021, 9:43 PM

#

Kio if you are observing your own component you need to implement that method

#

are you lerping the movement? there must be some trick like telling character to move in a direction and not stop until you got that other packet telling you to stop, you have to predict in some way the direction its going to not have hitching like this

#

i dont know the exact process thought

fast stone Jan 13, 2021, 9:45 PM

#

@grim violet uh ok,

silent zinc Jan 13, 2021, 9:45 PM

#

in the PlayerComponent attached to the character, if it is the Opponent, then do this in Update() ```cs
gameObject.transform.localPosition = new Vector3(status.positionX, status.positionY, 0);

fast stone Jan 13, 2021, 9:46 PM

#

@grim violet i just follow tutorial ,and im scary if i look this man dont have that, i have same code and something not working

grim violet Jan 13, 2021, 9:46 PM

#

yeah there no lerping in that steve

#

its just drastically setting the position

silent zinc Jan 13, 2021, 9:47 PM

#

isn't that the best approach for a 2D game? :/

grim violet Jan 13, 2021, 9:47 PM

#

Kio you have to extend your class with IPunObservable, then create a method like this

sorry for my english can be rly bad

if you physic you use AddForce to move character

#

sorry, the Input 's force axis

#

not sure what that is

#

seem to be for joystick to move slow of fast depending of pressure

#

you have to calculate that somehow with your movement

#

yeah it's basically the value of Input manager X and Y axis

grim violet Jan 13, 2021, 10:01 PM

#

yeah, you gotta calculate that with the lerp and all

#

i suck at math i cant give you the code on that

#

lol

#

probably all around the web thought

#

what happens if i use the same AddForce with the input values?

#

i mean, for now it seems to work

grim violet Jan 13, 2021, 10:03 PM

#

addforce will use physic to move your character

#

you probably just want that locally

silent zinc Jan 13, 2021, 10:03 PM

#

why?

grim violet Jan 13, 2021, 10:03 PM

#

if you start moving other player with addforce it might get weird result

#

you move with add force and send your own packet that way
