Not sure if this is the best place to ask about this, but I am a bit confused about the project structure of a multiplayer unreal game. If designing a game that is intended to run dedicated servers, is the dedicated server the same "project" as the game client? if so, how do you differentiate the behaviour that the server should do, vs the client? (regarding what authority to give actors etc.)

https://wiki.unrealengine.com/Replication

Replication

#

I think that is a pretty good wiki to answer your question.

worn turret Feb 2, 2019, 6:28 AM

#

Good call. Ill take a full read through this soon and see if that clears up my questions

thin stratus Feb 2, 2019, 9:19 AM

#

@worn turret could also read my compedium

#

Pinned to the channel

#

And yes, the dedicated server is the same project. In cpp you can mark code as server only, so clients won't compile that, but for bp projects I'm pretty sure it packages all code anyway

hello, i need to show widget only for players who overlap with trigger , now it shows to everyone ,, can someone help ,, ?

thin stratus Feb 2, 2019, 11:36 AM

#

OnOverlap->SwitchHasAuthority->Remote->OtherActor->CastToPlayerCharacter->IsLocallyControlled->TRUE->ShowWidget.

#

@foggy hedge

foggy hedge Feb 2, 2019, 11:37 AM

#

@thin stratus thank you so much i ll try it now

thin stratus Feb 2, 2019, 11:37 AM

#

Actually, you can skip the "SwitchHasAuthority->Remote" if you have a ListenServer setup

foggy hedge Feb 2, 2019, 11:42 AM

#

@thin stratus it works, but not for server ...((

thin stratus Feb 2, 2019, 11:58 AM

#

Did you use or not use the SwitchGasAuthority part?

#

what happens with dynamically spawned UObjects with rpc-s? can I pass one as a parameter for an rpc call? What happens in the other side, will it be GC-d randomly, or can I assume that it will be alive during the function call? 🤔

#

seems like I can't do that

winged badger Feb 2, 2019, 2:26 PM

#

UObjects arent replicated by defaut @lethal depot

#

If they are, something most likely an Outer Actor will manage its lifetime, and all you will be passing is a NetGUID

#

In short - you can as long as its replicated, otherwise you will just get a nullptr

lethal depot Feb 2, 2019, 2:37 PM

#

I see, my new idea is to pass the UClass and an FArchive as parameter to the rpc call with the necessary data so the object can reconstruct itself
I want to create a command queue

winged badger Feb 2, 2019, 2:37 PM

#

It doesn't even matter if its dynamically spawned, with UObject::IsNameStableForNetworking { return false ; }

#

Implementation you can't reference ones liaded from package directly either

#

Loaded*

#

Mightbe easier to just replicate the thing

lethal depot Feb 2, 2019, 2:40 PM

#

replicate what exactly? 🤔

winged badger Feb 2, 2019, 2:40 PM

#

The UObject

#

You need to override its IsSuportedForNetworking

lethal depot Feb 2, 2019, 2:41 PM

#

I have found a guide for that, yep

winged badger Feb 2, 2019, 2:41 PM

#

And Outers ReplicateSubobjects

#

One bit of trivia, you can instantiate and replicate UObjects with ActorComponent as Outer

#

But the Replicated UObject will change itd Outer to Owning Actor

#

Silently and without warning, ofc

#

Replicating it is easier and saner then hacking in a replication roundabout

lethal depot Feb 2, 2019, 2:46 PM

#

yeah but using replication instead of RPCs sounds like a nightmare from my systems point of view

winged badger Feb 2, 2019, 2:47 PM

#

You cant RPC something that doesnt exist on both sides

lethal depot Feb 2, 2019, 2:47 PM

#

I can RPC primitives and structs and that is enough for me 😄

winged badger Feb 2, 2019, 2:48 PM

#

If they are in Array or Queue or some such

#

You can use FFastArraySerializer to get client side notifications

#

NetworkSerialization.h has all the info in comments

manic pine Feb 2, 2019, 2:50 PM

#

ye the fastarrayserializer is nice

#

cept the unordered part

winged badger Feb 2, 2019, 2:52 PM

#

Annoying thing about replicating primitives and reconstructing is that even after you reconstruct it, you still can't reference it over network directly

#

As far as Unreal cares, its not the same object

#

@manic pine unordered can be worked around, you have wrak pointer to object and index in your FFastArraySerialiterItem derived struct

#

And you manage their lifetimes with a TArray

manic pine Feb 2, 2019, 2:58 PM

#

yeah, just a bit of a hassle

jade gazelle Feb 2, 2019, 3:08 PM

#

What would be the best way of implementing a loot system that was somewhat protected from reverse engineering? That is, preventing clients from looking into game files to see what enemies drop what items.

#

The only thing I can think of is storing everything on an external database and then querying that every time an enemy dies

#

That seems kind of excessive though

manic pine Feb 2, 2019, 3:13 PM

#

WITH_SERVER_CODE perhaps

#

or just keeping it in a file not distributed with the client

#

unless you meant just listenserver?

past totem Feb 2, 2019, 3:23 PM

#

Best way to check if the client is the same version as the server before letting him join?
@ me please

#

Also, cheat wise, if I have a custom event that runs on the server with input values, can a cheat client run it with it's own custom values and use it to cheat?
@ me please

winged badger Feb 2, 2019, 3:35 PM

#

@jade gazelle that seems a bit redundant, after a short while just statistics will let them know everything they want to know

jade gazelle Feb 2, 2019, 4:19 PM

#

@winged badger probably unnecessary in the grand scheme of things and how quickly information propagates now. Still just trying to maintain some semblance of mystery

#

I might just handle all of that stuff on the database so changes can easily be made w/o having to modify the game source code

heavy marlin Feb 2, 2019, 5:40 PM

#

Might be auto possess settings?

twin juniper Feb 3, 2019, 1:40 AM

#

Whats the best way to test steamworks integration? I've set up a lobby system etc, should I use a VM to test it on a shipping build?

#

or is there a better way

thin stratus Feb 3, 2019, 10:41 AM

#

2 PCs.

#

You can also try the VM, but VMs are usually pretty limited in resources.

#

@twin juniper

twin juniper Feb 3, 2019, 1:39 PM

#

Fuuun.. Thanks

#

Also is there a way to see which player controller is the "host" so to speak?

#

Also I just realized, you're the absolute MVP who wrote the compendium, thanks for that. 👌

thin stratus Feb 3, 2019, 1:49 PM

#

No biggie (:

#

Well, depends on why you want to know that (PC being host)

#

There are multiple ways to check who is the server

#

@twin juniper

twin juniper Feb 3, 2019, 2:38 PM

#

@thin stratus well I'm trying to figure out some general things about sessions, I'm using steam in this case.

By default, are sessions just listen servers on whatever client created them?
Do these servers require additional setup if you want to test with machines on different networks (port forwarding)

@thin stratus

#

For context, I have a pre round lobby that only the session creator can start, I'm assuming in this case the listen server is the session creator when using steamworks?

thin stratus Feb 3, 2019, 2:51 PM

#

@twin juniper A session is just a set of data/info

#

Usually the server opens up that session

#

That can be a Listen Server or also a dedicated server

#

Other people find the session and use its data to join the server

#

Steam uses NAT punchthrough so you don't have to port forward, at least as a listenserver

#

The whole thing about only having the server start a round is pretty much not connected to sessions at all

twin juniper Feb 3, 2019, 2:55 PM

#

Right that makes complete sense

#

I'm going to try out some stuff then, I'm trying to remake a local coop game I made for steam and I'm a bit new to networking still haha

thin stratus Feb 3, 2019, 2:57 PM

#

You can use the simple "IsServer" function to hide and show ui elements

#

A client pressing the button wont do much anyway as the code to travel to a new map is limited to servers only

#

@twin juniper

twin juniper Feb 3, 2019, 3:12 PM

#

That's a fair point

#

Alright thanks for the tips, I'll post here again if I manage to horrendously mess up

#

Oh a small inquiry, do I need to pass every widget button event through the PC?

#

It seems like it'd get messy if you have a lot of UI you need replicated

meager spade Feb 3, 2019, 3:19 PM

#

you can get the pawn from the widget, etc but yeah you have to send replicated stuff out, but not just via the PC, you could do it via anything, playerstate, or whatever

thin stratus Feb 3, 2019, 3:21 PM

#

It helps wrapping specific logic into Components that are replicated and sit on the PC

#

at least organization wise

twin juniper Feb 3, 2019, 3:24 PM

#

That makes sense, I'll use components then

twin juniper Feb 3, 2019, 5:15 PM

#

Is a player created by using the CreatePlayer node the same as a player that would join through online play?

#

As in, does it get added to the player array in the gamestate

twin juniper Feb 3, 2019, 6:10 PM

#

I seem to be having issues with my player controllers when setting up, it appears that only the first player gets a player controller while the rest doesnt, this happens when testing by selecting to play with 2 players for example

#

nevermind, I just fucked up my replication, fixed it now 😃

crystal crag Feb 3, 2019, 7:01 PM

#

Hey everyone. I am taking my first stab at the AbilitySystem and I have it pretty close to working (I think). I have a basic ability mapped to the LMB (player swings a sword). When I click LMB with no dedicated server, everything works (even a listen server is working fine). When using a dedicated server I see in the logs the ability being activated but the target's health never gets modified. Does anyone have any general tips are to what to look for?

#

I'm following a mixture of the ActionRPG template and using this guide: https://wiki.unrealengine.com/GameplayAbilities_and_You#Data-driven_Initialization_of_Attributes

GameplayAbilities and You

#

As far as I can tell, UAttributeSet/Attributes are always replicated by default

#

That might not be enough information, I just don't know how to put in my entire series of classes to where people would care enough to read / analyze them, so I was going for a more generalized approach

winged badger Feb 3, 2019, 7:11 PM

#

using an animation to drive the hit logic and dedicated server is not running animations?

crystal crag Feb 3, 2019, 7:12 PM

#

Let me double-check. I thought I had the dedicated server running animations but who knows. I've deleted and started over so many times it all is beginning to blur together

#

@winged badger thank you. In this restart attempt I had forgotten to re-apply that setting

#

That fixed it 😃

twin juniper Feb 3, 2019, 8:12 PM

#

Hi, I can't seem to find sessions I create on my second machine

#

Using steamworks as subsystem

grand kestrel Feb 4, 2019, 6:21 AM

#

Christ it gets buggy as when you uncheck 'Use Single Process'

#

Its now ruined the project

#

Can no longer build server targets

#

🤷

winged badger Feb 4, 2019, 6:22 AM

#

what does?

grand kestrel Feb 4, 2019, 6:25 AM

#

Running PIE with 'Use Single Process' unchecked corrupts the project preventing compiling server targets

#

On 4.20 at least

#

Oh, sorry, it corrupts the source engine build

#

Gonna have to delete intermediate, takes hours to rebuild all this crap

#

Coz I use Debug Editor, DebugGame Editor, DebugGame Server, DevelopmentEditor, DevelopmentServer, so thats 5 engine builds

#

Guess its time for a break and never using that setting again :/

worthy perch Feb 4, 2019, 6:34 AM

#

May I ask what symptoms your corrupted source engine build exihibit? (I could not phrase this question properly.)

#

It seems strange that a setting that doesn't affect code, as far as I know, would corrupt source code.

grand kestrel Feb 4, 2019, 6:40 AM

#

Sorry I didn't keep the logs, it was all nonsensical stuff related to PIE from the Engine's Intermediate folder, tons of error spam from there

worthy perch Feb 4, 2019, 6:41 AM

#

Hmm, alright. Were there any attempts to fix it?

grand kestrel Feb 4, 2019, 6:41 AM

#

In what way?

#

The intermediate folder isn't something you fix, you delete it and rebuild

worthy perch Feb 4, 2019, 6:41 AM

#

Just general debugging.

#

Well, you can regenerate the visual studio files.

grand kestrel Feb 4, 2019, 6:41 AM

#

For the engine not project..

worthy perch Feb 4, 2019, 6:42 AM

#

Oooh.

grand kestrel Feb 4, 2019, 6:42 AM

#

Thats why its so painful

#

5 engine targets

worthy perch Feb 4, 2019, 6:42 AM

#

Damn, that's rough...

grand kestrel Feb 4, 2019, 6:42 AM

#

I'll just do the essential ones first and set the others going when I take a break/go to sleep, etc

twin juniper Feb 4, 2019, 8:05 AM

#

hello i need help with LAN game
i got this error when create session:

📎 Screenshot_1.png

potent prairie Feb 4, 2019, 8:28 AM

#

Hey, does anyone know if there's a way to keep a clients game window "active" even if minimized?

#

Reason I ask is because when I test multiplayer, if the client minimizes the window, his ping jumps to 1000+ and then the server/client stop registering hits as well

#

I'm afraid a player could just minimize his game as an exploit, to avoid getting hit, or whatever if that makes sense

#

Maybe this doesn't happen in shipping builds, but I havent tested that build yet.

grand kestrel Feb 4, 2019, 9:01 AM

#

It's weird that you have that issue in the first place

#

Clients shouldn't be handling that stuff either

potent prairie Feb 4, 2019, 9:44 AM

#

well the ping jumps up because when the game loses focus, like minimizing, its like windows stops giving it resources or something so I can see why the ping would jump. Just wondering if there's a way around that

pallid mesa Feb 4, 2019, 10:45 AM

#

Did someone have this issue on UE 4.21.2 where a net multicast marked as unreliable will only fire once in a component? (single proc)

#

I think I've figured out but I don't understand why it just works once

#

oka I basically missed a call to AActor::UpdateReplicatedComponent(UActorComponent* Component)

#

which is handled by SetIsReplicated

grand kestrel Feb 4, 2019, 10:54 AM

#

Somehow seem to have permanently corrupted my project. I was doing frequent DebugGame Server builds which worked no problem, and then I changed the option 'use single process' to false in Editor Preferences->Play->Multiplayer Options, so it loads the server externally and connects to that, needed it to test a certain system. I renamed a struct (before ever doing this but within the same editor instance, i.e before closing/reopening) and it results in an error (on the server's side):

[2019.02.04-10.44.33:801][  0]LogClass: Warning: Property GameRules of GameRules has a struct type mismatch (tag STRUCT_REINST_GameRules_0 != prop FallbackStruct) in package:  ../../../../../../Projects/Reliquary/Plugins/VProjectilesProj/Content/Extra/GameInstanceBP.uasset. If that struct got renamed, add an entry to ActiveStructRedirects.
[2019.02.04-10.44.33:803][  0]LogClass: Warning: Property GameRules of GameRules has a struct type mismatch (tag FallbackStruct != prop GameRules) in package:  FObjectReader. If that struct got renamed, add an entry to ActiveStructRedirects.```
And now when I compile ``DebugGame Server`` or ``Development Server`` targets it results in mass irrelevant error spam:
https://pastebin.com/KxCu7Aav

Pastebin

1>------ Skipped Build: Project: DotNETUtilities, Configuration: D...

#

Theres no reason it should need an ActiveStructRedirects entry either

#

This is on 4.20

#

And I never hot reload, ever, I'm always running in debugging

#

Seems like some astronomical engine bug caused this and I'm never going to find what it is or why because its too rare 🤷

#

But I'm also not going to recreate the project lol

#

Ah got rid of the server log errors by resaving all the BPs

fleet raven Feb 4, 2019, 11:04 AM

#

that server build is probably fixed by just doing a clean

grand kestrel Feb 4, 2019, 11:04 AM

#

I reinstalled the source engine from scratch

#

Well, deleted it, cloned it, built it, etc

fleet raven Feb 4, 2019, 11:05 AM

#

err

#

what is it even doing

#

did you add an invalid module dependency

grand kestrel Feb 4, 2019, 11:05 AM

#

I haven't touched the dependencies in ages

fleet raven Feb 4, 2019, 11:05 AM

#

it seems to be trying to build editor/developer modules for the server

#

Module.BlueprintGraph.gen.3_of_3.cpp this does not belong on a server

grand kestrel Feb 4, 2019, 11:06 AM

#

Oh I see where it might be

#

I added a plugin that hadn't been tested with a server build and realized it's build.cs didn't have if (Target.Type == TargetRules.TargetType.Editor) for "UnrealEd" include, so maybe its that

#

Old plugin lol

fleet raven Feb 4, 2019, 11:08 AM

#

a lot of plugins are structured incorrectly (doing weird stuff instead of clean runtime/editor module split)

#

so that could certainly cause it

grand kestrel Feb 4, 2019, 11:09 AM

#

Yep that seems to be it

#

Forever re-learning the lesson of not jumping to conclusions huh

elfin cliff Feb 4, 2019, 11:31 AM

Guys, looking for some advice/opinions. In a multiplayer app we've built, we have a server running in India. I am able to connect fine. Another user, who is in germany, is able to connect fine via his mobile hotspot, but not via the company guest network. Another user in UK is not able to connect at all.
What do you think is wrong?

twin juniper Feb 4, 2019, 2:34 PM

#

For some reason, when I try to loop through a bunch of values and set their value, the repnotify function is not always being called

#

But it is setting the value 100% of the time

#

its only the rep-notify where we have an issue

#

Anyone have any ideas about this issue?

guys quick Q - DedicatedServer - PIE testing .... how do i get the dedicated server to open up in a new window (like if you put -log at the end of a .exe's shortcut)?

#

the server runs fine when i launch it on its own.... i've been in teams where when press PLAY in editor - it launches the Dedi seperately before it launches the client... .but for some reaosn this new projec ti'm on it isnt doing it.

winged badger Feb 4, 2019, 4:05 PM

@twin juniper that blueprint or c++?

Hi Guys! I´m making a Android game. In my editor CREATE SESSION and JOIN SESSION works fine, but not in the device. The problems come with DefaultPlatformService=GooglePlay. I use google play and I need can access LAN too.
If I change DefaultPlatformService=LAN, Join Sessioo and Create session works, but I can connect to Google Play.
I need both services. How I can do that?

twin juniper Feb 4, 2019, 4:35 PM

#

I faced this problem when i was making multiplayer game using (OnlineSubsystemSteam)
So, if i logged in to my account on steam LAN has no effect
When i logged out from steam and close it
LAN work fine.

#

@vale steeple
So u should force engine to use LAN..
use this consoloe command on success when u create session:
open LevelName?listen?IsLan=1

vale steeple Feb 4, 2019, 4:40 PM

#

ok, then I don´t will use Create and Join Session, and back to the old method with console commands?

#

📎 unknown.png

#

Where I have "listen" I put ?listen?IsLan=1?

twin juniper Feb 4, 2019, 4:43 PM

#

Use the console command it is better

#

No sorry not this one

#

Wait a moment

vale steeple Feb 4, 2019, 4:45 PM

#

And for join a game, I need to do something special? I use command "open IP"

twin juniper Feb 4, 2019, 4:46 PM

#

For join game just use Join Session

#

The problem is i dont have computre right now....
Tomorrow i will just show u the right way when i have the computer

vale steeple Feb 4, 2019, 4:48 PM

#

ok, but I can start trying all this! thanks so much!!

twin juniper Feb 4, 2019, 4:48 PM

#

@vale steeple dont use the function at the my picture it is wrong
U need to use the normal Excute Consoloe Command and the target is Player Controller

past totem Feb 4, 2019, 4:50 PM

Anyone able to help. I created a session for my server using the DefaultPlatformService=Steam and it says it's successful. I can also connect via open IP command. But when I search for sessions it doesn't find it (no error, just finds 0 results)
If I change the config to DefaultPlatformService=Null then it finds it on my PC but not for other players (0 results).

how can I create an actor and place it on the map inside bp from a client's perspective (only one client can see,interact with it while the others can't)?

faint parcel Feb 4, 2019, 8:24 PM

#

Hello everyone, I just recently started playing around with Networking in Unreal and I am trying to understand the different use-cases for RPCs and Replicated Properties.
For instance, do I set a replicated property "isShooting" on a player, or do I send an RPC (marked reliable I suppose) to tell the server and later every client to start shooting? (for effects sake).
My gut is telling me to go with a local shooting effect, called immediately as the local player starts shooting, and then send a Server RPC to tell the server that the local client is shooting, the server then tells every client to show shooting effects for the given client.

manic pine Feb 4, 2019, 8:26 PM

#

either works, though a property has the advantage of reaching new clients as well

#

ie player1 starts shooting, player2 joins

#

with rpc, player2 then doesnt see player1 shooting, with property he does

@faint parcel im pretty sure thats the right way

@limpid notch spawn it from a client instead of the server

limpid notch Feb 4, 2019, 8:42 PM

#

@twin juniper thanks im trying to have each client have their own 3d widget actor but it seems that after each client creates his own actor only the first client can interact with it , while the second can't. Do you know why is that happening?

twin juniper Feb 4, 2019, 8:45 PM

#

@limpid notch Yes, because UI is client only

#

You need to pass it through the player controller

#

Does anyone know if theres an easy way to test bad connection playability? Can I fake ping somehow?

limpid notch Feb 4, 2019, 8:48 PM

@twin juniper and how can i pass it through the PC?

limpid notch Feb 4, 2019, 8:55 PM

@twin juniper So what you are basically telling me is that the first client that enters the server has authority over all such 3d umgs and that for another client to use the 3d UMG , it has to somehow get permission from the first client thats the "god of umgs"?

twin juniper Feb 4, 2019, 8:55 PM

#

I assumed you were playing with a listen server

#

what are your multiplayer settings right now

limpid notch Feb 4, 2019, 8:56 PM

#

the client just enters a session using the online subsystem there are no settings that i assign to the session

twin juniper Feb 4, 2019, 8:59 PM

#

who made the session

limpid notch Feb 4, 2019, 9:00 PM

#

a dedicated server

potent prairie Feb 4, 2019, 9:08 PM

#

have UMG widgets run on Local Controller

limpid notch Feb 4, 2019, 9:10 PM

#

how should that work? Currently each client creates its own 3d Widget actor but only the first client(who btw , isn't the server since everything is run on a dedicated server) can interact with its widget , while the other clients can't

faint parcel Feb 4, 2019, 9:13 PM

#

Thanks for the answers, btw - I just went afk for a while, appreciated the response!

potent prairie Feb 4, 2019, 9:14 PM

#

No, widgets are client only. I have an actual dedicated server and I make sure I load up all widgets locally

#

The server can send a command to load the widget, but not load the actual widget on server

limpid notch Feb 4, 2019, 9:14 PM

#

and doesn't client only mean that every single umg can be assigned to only one client?

potent prairie Feb 4, 2019, 9:14 PM

#

you'll get accessed none errors when the server is trying to load the widget itself

#

Well what I do is when the player joins the server, the PC loads up the class selection widget locally. Whatever the player chooses gets sent to the gamemode, which is server only, and then the gamemode handles the player spawning. The player spawns, and then I run an initialization script on the playercontroller and I locally load the UI there

#

There's probably a ton of ways to do it, but that;s how I do it and it works

limpid notch Feb 4, 2019, 9:17 PM

#

yeah but in my case im trying to assign a 3d Widget actor to each client for itself but it only works for the first client

potent prairie Feb 4, 2019, 9:18 PM

#

might mean the server is only assigning it to index 0

#

which means player 1

#

so I would check that you're not using Get Player Controller or whatever that is with the index of 0 on it

limpid notch Feb 4, 2019, 9:20 PM

#

it shouldn't, since im spawning the actor inside a function thats executed by the client x and this client x can see only its actor and the other clients cannot see his (im spawning them in different locations) so typically it should be assigned to client x

potent prairie Feb 4, 2019, 9:20 PM

#

hard to know without going through your scripts haha

sharp pagoda Feb 4, 2019, 9:21 PM

Wait what are you doing? Just spawn the widget actor if IsLocallyControlled() after being possessed

worthy perch Feb 4, 2019, 9:30 PM

#

Did you already check the possible reasons for failure in Steamworks' documentation?

#

false indicates one of the following conditions:

    The Steam client isn't running. A running Steam client is required to provide implementations of the various Steamworks interfaces.
    The Steam client couldn't determine the App ID of game. If you're running your application from the executable or debugger directly then you must have a steam_appid.txt in your game directory next to the executable, with your app ID in it and nothing else. Steam will look for this file in the current working directory. If you are running your executable from a different directory you may need to relocate the steam_appid.txt file.
    Your application is not running under the same OS user context as the Steam client, such as a different user or administration access level.
    Ensure that you own a license for the App ID on the currently active Steam account. Your game must show up in your Steam library.
    Your App ID is not completely set up, i.e. in Release State: Unavailable, or it's missing default packages.

@worthy perch Actually, one of those listed was the problem. I think I see why I was able to have it work on my PC, but not the other

Since I am the on the Steam Account associated (dev) with the steam_ appid, since it's not release state, public can't use it. But I then tried out 480 on it, and it's working. which is good, that means I can now go back to my other project and figure out the issue. So thanks for CPing that.

Just to be clear regarding the UWorks discussion above: I don't know if ARK uses it or not. What can be seen in that screenshot posted above is that, with the help of UWorks, it's possible to have a UMG which interacts with Steam's server browser, the one found in the Steam application, under "View|Servers". I could've shown servers from ARK, CoD and CS:GO in one list if I wanted to.

Failing to grasp this shows beginner-level knowledge of UE4 networking and Steam and would likely translate to a headache for me and a lack of satisfaction for you. Therefore, if you find yourself confused by the above-mentioned, it's best for you to stay away from UWorks until you learn the basics of UE4 networking and Steam.

fleet sluice Feb 4, 2019, 10:55 PM

@past totem A database could be somewhat sufficient, though costs and stress have the potential of skyrocketing and require more thorough maintenance. For cross-platform games, you need to add the IP:port combinations of each server to that database, but also remove them when the server ends. This is just a bare minimum. If I tell you my IP:port, where you would find a server, you wouldn't be able to connect to it unless I personally change the settings in my router/NAT (it's called "port forwarding" or "NAT traversal"). If you plan to use dedicated servers, you don't worry about this part because server admins will know how to configure their routers/NATs. But if you aim for listen servers, the database would be almost useless by itself.

past totem Feb 4, 2019, 10:56 PM

Yep I'm just doing dedicated servers

#

For cross-platform games, you need to add the IP:port combinations of each server to that database, but also remove them when the server ends. Yep that's what I'll probably do

Is there no way to use the Null network thing with ports?

I did too, once. But every discussion that starts with "I have a problem with OnlineSubsystemSteam" tends to result in tons of pages of "solutions".

Everything uses ports underneath. "JoinSession" is the same as "ExecuteConsoleCommand("IP:port")". I have no idea what you're trying to achieve with OSNull with this little information

There's a UWorks (Multiplayer) version for $80 by the way. But it's not going to be with "JoinSession" and "CreateSession". It's a much more flexible wrapper so it's naturally a different workflow. The host/join examples are there, but don't expect it to be some 2 min "plug-n-play" stuff.

Yes, there were a few. I had a gentleman ask me the same thing recently. 4.19 and 4.20 had some fundamentally broken stuff which prevented connections with OnlineSubsystemUWorks enabled so I stopped supporting those. What's the particular problem?

This is the amount of functions you get with UWorks.

You should get the 4.21 version from the launcher. That's the only version I consider good since 4.18

So I'm currently trying to implement networking in my shooter project that previously was singleplayer only.

I need some advice regarding bullet spawn location & rotation, previously I've just spawned the bullet at a socket located on the weapon which is a child of the player mesh which is driven by animation which is not run on the dedicated server. I would prefer not do run animations on the server I think(?)

I'm guessing that letting the client pass along the transform is a terrible solution...

potent prairie Feb 5, 2019, 2:37 AM

#

If its a bullet, why not just use a line trace? It's moving so fast that you might not need it to be a projectile right?

#

and you're correct in that you do not want the server running the animations and all that

icy nacelle Feb 5, 2019, 2:47 AM

#

How to I increase the session size?

sharp pagoda Feb 5, 2019, 2:49 AM

#

@chilly pendant Run animation on the server until you can prove it has a significant performance cost through profiling, don't let the client decide where to shoot from. If you can prove it has high cost I can show you how to setup instantaneous anim evaluation on the server so it doesn't have to tick every frame.

#

Quick Tip:
To force engine to use LAN just use this command after you create session(On Success):
open LevelName?listen?bIsLanMatch=1

fleet raven Feb 5, 2019, 7:46 AM

#

so if a client loses connection to the server while moving forwards,

the listen server will show the client make 5 large laggy steps and freeze after half a second
another connected client will show the player walk off to infinity and beyond

#

why is this?

potent prairie Feb 5, 2019, 7:49 AM

#

that happens in every game, who knows

fleet raven Feb 5, 2019, 7:51 AM

#

well it's terrible, you'd expect the client to show what the server shows

potent prairie Feb 5, 2019, 7:53 AM

#

sorry I'm not sure haha I just can recall all these multiplayer games where a player would d/c and be walking to infinity or sliding or whatever

#

I've noticed differences between test builds and shipping builds when playing on my ded server, so make sure you run a shipping build from time to time to make sure everything is working

fleet raven Feb 5, 2019, 7:56 AM

#

interesting

#

do you remember any specific differences?

potent prairie Feb 5, 2019, 7:57 AM

#

yea the most significant is that if i minimize a test build, it freezes and ping jumps to 1000000

#

shipping doesnt do that

fleet raven Feb 5, 2019, 7:57 AM

#

hm

potent prairie Feb 5, 2019, 7:57 AM

#

so testing out 2 clients on one PC with a test build becomes significantly harder

fleet raven Feb 5, 2019, 7:57 AM

#

that's not happening for me in development and debug builds

fleet sluice Feb 5, 2019, 9:32 AM

@fleet raven Over the network, movement relies on a technique called "prediction" or "extrapolation". To make sure players don't see laggy/jittery movement, their clients use the last information they received from the server to try to predict what the player will do next. So if a player is moving in a straight line before they disconnect, the server will have accurate data and see it's character lagging, but until it "declares" the disconnect, the clients won't have any new data so they just assume the player is still moving along that straight line until they receive the server's "yo, this guy disconnected" notification.

#

This technique and others are industry standards nowadays, unfortunately.

fleet raven Feb 5, 2019, 9:33 AM

#

shouldn't the server be sending regular updates to the clients regardless of whether the player has disconnected?

#

so it would stop on the client much like it does on the server

fleet sluice Feb 5, 2019, 9:34 AM

#

Not sure what happens in UE4 when the "lag out" appears

#

Maybe they decided it's not worth sending updates at that point

fleet raven Feb 5, 2019, 9:35 AM

#

maybe the client should also stop movement then instead of playing the last known move forever

#

it's very strange how it becomes completely de-sync like that

#

this also has the effect that if someone lags out and you can see their player walking around somewhere, you can walk through it since it's not there on the server side

fleet sluice Feb 5, 2019, 9:38 AM

#

Perhaps it's an attempt to compensate packet loss. The server doesn't expect a disconnect to occur, so it just keeps on hoping it's just rubber banding so it tries to filter out those updates to avoid making the clients simulate a laggy player themselves. In BF1, for example, if someone has 400 ping, all clients see the player lagging.

storm veldt Feb 5, 2019, 10:35 AM

it's a custom variable in the blueprint player state, that's set from the player state at begin play

There is no Object on the other players

ok I wonder why it's even replicated now ^^

#

ok so how to best check if the player state is the local one?

btw thanks for your network compendium ^^ helped me quite a lot, as this is the first multiplayer project I'm working on

#

and I still wonder why it's not working for the server/local player when he's talking? it's always returning false.

the lower part... well I'll see how that works if I got the first check right

ember needle Feb 5, 2019, 10:40 AM

All, I'm trying to get a player travel on a moving platform in MP. I attach the player to the platform (attachto), and the platform moves onTick. The issue I have is a little weird. To avoid "jiggling", I SetReplicateMovement to false, however when I do that on the SERVER (and only there) TryGetPawnOwner in the animation BP returns None, hence all animations do not work ON SERVER ONLY. I've tried SetReplicateMovement on server only, on client only, on locally controlled only. Same thing.

#

Asking gurus here... because I'm not getting it.

#

This is easily reproducible BTW...

bitter oriole Feb 5, 2019, 10:48 AM

#

@ember needle It's weird if you just toggled movement replication, but to be clear, "owner" is a concept tied to replication

ember needle Feb 5, 2019, 10:48 AM

#

Yes, but I'm not removing actor replication

#

just movement

bitter oriole Feb 5, 2019, 10:48 AM

What do you call TryGetPawnOwner on ?

ember needle Feb 5, 2019, 10:49 AM

#

AnimBP

bitter oriole Feb 5, 2019, 10:49 AM

#

The anim instance ?

ember needle Feb 5, 2019, 10:49 AM

#

I call it in the animation blueprint of the actor

#

Maybe there's another way to stop movement replication somehow? or make it more loose

#

I also tried making the character movement component replicated as well but obviously that doesn't change anything

#

This happens only on the SERVER if a CLIENT gets on a platform

#

if the server gets on the platform on the server, all ok

#

clients are always ok

#

for some reason TryGetPawnOwner returns none on SERVER if replicate movement is dynamically set to off for a client

#

all other cases are good

#

CORRECTION

The issue is that when I SetReplicateMovement to false then the animation UPDATE is not called ON SERVER ONLY

@ember needle That might be by design

Character animation is driven by movement

ember needle Feb 5, 2019, 11:36 AM

...happens only on server

#

why is it called on clients then...

bitter oriole Feb 5, 2019, 11:37 AM

No idea, but generally, I'm not sure character movement comp has support for not replicating anymore

ember needle Feb 5, 2019, 11:37 AM

#

and again i'm not taking away movement

#

ok then why is there such a node 😄

#

but indeed there's an issue there

bitter oriole Feb 5, 2019, 11:38 AM

#

There's such a node because SetReplicateMovement is an AActor method

#

And most Actor methods are exposed to BP

#

Doesn't mean every actor can work with or without replication

ember needle Feb 5, 2019, 11:38 AM

#

I don't understand what "replicate movement" has to do 1. with character movement component (that I'm not touching) and 2. with the animbp

bitter oriole Feb 5, 2019, 11:38 AM

#

SetReplicateMovement (false) disables the CMC

#

Probably

ember needle Feb 5, 2019, 11:39 AM

#

no

#

sorry, i still don't understand

#

who cares about the CMC!

#

i'm not setting it

#

animbp has nothing to do with CMC

#

replicated movements has nothing to do with CM

bitter oriole Feb 5, 2019, 11:40 AM

#

ANimBP is very much driven by CMC

#

And CMC is handling all movement replication

ember needle Feb 5, 2019, 11:40 AM

#

why is so, animbp totally works even without CMC

bitter oriole Feb 5, 2019, 11:41 AM

#

I'm not saying anim BPs as a concept require CMC, I'm saying CMC specifically affects the animation BP

#

For example it's responsible for ticking it

ember needle Feb 5, 2019, 11:41 AM

#

I have actors with animations without a CMC

#

and ticks still run

#

so I am confused

It will have no direct effect on clients

It can have indirect effects

ember needle Feb 5, 2019, 11:47 AM

#

ok

bitter oriole Feb 5, 2019, 11:47 AM

#

Since you're stopping the CMC, of course, that's going to affect clients

ember needle Feb 5, 2019, 11:47 AM

i'm not stopping the CMC....

stranger, thank you for trying to help

i don't want to lose any more of your time

will try to find an alternative

bitter oriole Feb 5, 2019, 11:53 AM

@ember needle Setting SetReplicateMovement() to false will disable most of the CMC

🤷

ember needle Feb 5, 2019, 11:53 AM

So with the CMC disabled, the animbp also does not get updated?

Has anyone worked with 3d widgets before? I'm trying to make each client spawn his own 3d widget actor and interact with it but the problem is that only the first client can interact with his 3d widget actor , while the actors cannot (maybe all the umgs are assigned to that first client and only he can interact with them). I tried creating the widget on client in the PC bp and assigning the widget to the actor componet of the actor newly created , but the same problem happens. Here is the code

📎 unknown.png

#

also this is how the actor im spawning looks like

#

Im also using recieve hardware input for the widget component , since its just a normal umg but in 3d

@bitter oriole as a feedback, maybe this could be related to my issue:

void ACharacter::PossessedBy(AController* NewController)
{
    Super::PossessedBy(NewController);

    // If we are controlled remotely, set animation timing to be driven by client's network updates. So timing and events remain in sync.
    if (Mesh && bReplicateMovement && (GetRemoteRole() == ROLE_AutonomousProxy && GetNetConnection() != nullptr))
    {
        Mesh->bOnlyAllowAutonomousTickPose = true;
    }
}

chrome bay Feb 5, 2019, 1:01 PM

#

Why are you attaching the player to the platform?

#

Character Movement already supports walking on a moving platform via the 'Base' system

ember needle Feb 5, 2019, 1:02 PM

#

the character is seated

chrome bay Feb 5, 2019, 1:02 PM

#

Then you need to disable movement entirely

ember needle Feb 5, 2019, 1:04 PM

#

disabling movement still does not solve the issue, since animation bp's update still does not get called on server for the attached actor

chrome bay Feb 5, 2019, 1:04 PM

#

Is this a dedicated server?

ember needle Feb 5, 2019, 1:04 PM

#

no

#

listening

chrome bay Feb 5, 2019, 1:05 PM

#

Oh hang on

#

Yeah so you need to disable movement, then set bOnlyAllowAutonomousTickPose to false

#

Because usually, the character mesh animation is ticked by the movement component

Doubt you can do it from Blueprint, unless bOnlyAllowAutonomousTickPose is exposed

ember needle Feb 5, 2019, 1:06 PM

#

it's not but I can expose it

#

ouch not really

#

well I can add a function

#

and inherit

chrome bay Feb 5, 2019, 1:07 PM

#

You can just use a static BP function to set the flag on an arbitrary mesh

#

But you'll want to check to see if character movement overrides it anywhere else

#

Characters are very heavily tied to the movement component, as most of the time animation is driven by movement. Usually animations for characters are ticked by the movement component to keep things in sync

ember needle Feb 5, 2019, 1:08 PM

#

is there anyway I can call the animbp directly?

#

You can just use a static BP function to set the flag on an arbitrary mesh
lost you here

unique kelp Feb 5, 2019, 1:09 PM

In the context of using NetSerialize in a struct, is FArchive::Saving preparing the data to be sent, or reading the received data?

@ember needle - You can't tick the Anim BP directly no, at least definitely not in blueprint

ember needle Feb 5, 2019, 1:10 PM

#

ok thanks

#

so I just need to add a MyCharacter that inherits from Character, and add a function to set bOnlyAllowAutonomousTickPose is that correct?

Yeah you could do that

jade gazelle Feb 5, 2019, 1:37 PM

Been having a weird issue now for a while that I can’t seem to find the cause of. Thought I’d see it anyone here had any thoughts.

#

I have a widget component (nameplate) above player characters and NPCs in my game and they work fine, however the longer I am in game, they seem to drift and lose their position

#

There is no code whatsoever modifying their movement. They are just parented to the character mesh and then within that parented to the head bone

#

Is this maybe like a server/client desync that is getting exacerbated over time?

#

That doesn’t seem to make sense to me though because the character locations are obviously replicated so any server corrections should also correct the nameplates

unique kelp Feb 5, 2019, 2:01 PM

#

does the FArchive << operator do the inverse operation on saving and on loading? Seems confusing

chrome bay Feb 5, 2019, 2:06 PM

#

@unique kelp yeah it does

#

If you just do Ar << SomeInt

#

it will be correctly loaded / saved depending on what state the archive is in

ember needle Feb 5, 2019, 2:07 PM

#

@chrome bay and @bitter oriole I want to thank you both (great patience with me Stranger... thank you). All is needed to make this work is to expose a function in BP that sets the bOnlyAllowAutonomousTickPose and now everything works.
https://gyazo.com/6650eb1f1ad5a4482b900a31fd013abd

Gyazo

#

this allows the animation BP to still have a tick called even though the actor does not have movement replicated anymore.

its peer to peer. you dont want peer to peer, thats totally different from how unreal's multiplayer features work

you could create it but it will take some time, especially if youre new

why do you need peer to peer?

I try to make a 4 player Game and I doesent wont to make Server for it so if they want to play together they can if they make ther own Server in the game

dusky flower Feb 5, 2019, 4:54 PM

#

if they want to make their own server, then you need to make a server

rich vessel Feb 5, 2019, 4:58 PM

#

for steam or something

dusky flower Feb 5, 2019, 4:58 PM

#

its possible, peer to peer, its actually what a lot of older games did and rts games still do

#

but if youve ever played an old RTS game then you know that it lasts about 30 minutes before things start desyncing

#

thats cuz every client has to run their own code, because no one has authority over what is real

#

and with non-deterministic physics, things will get completely out of hand cuz physics is random to an extent

rich vessel Feb 5, 2019, 5:00 PM

#

is it possibly to host a Server from G-portal or something ?

dusky flower Feb 5, 2019, 5:01 PM

Hey guys this is a question about multiplayer widget interacting : can I have each client spawn its own 3d widget actor of the same class and interact with it individually using the widgetinteraction component? (by that i mean that client won't share the same 3d widget actor and that this actor won't be replicated)

thin stratus Feb 5, 2019, 6:42 PM

#

Widgets are generally not Replicated anyway

#

So spawning a replicated Actor that has a WidgetComponent in it, will not automatically make the Widget replicate.

#

So each Player should be able to interact with that on its own.

#

@limpid notch

limpid notch Feb 5, 2019, 6:44 PM

#

ok so should i just place tge actor on the map or spawn it using a server function?

#

also how can I make each player interact with the widget? It works for 1 client but when i go with more than one it doesn't work for either

#

@thin stratus

thin stratus Feb 5, 2019, 6:48 PM

#

No idea of you issues with the more than 1 player

#

But technically you can just place it int othe scene

#

It doesn't evne need to be marked replicated for that

limpid notch Feb 5, 2019, 6:50 PM

#

ok , thanks

twin juniper Feb 5, 2019, 7:13 PM

#

@limpid notch
Select widget component
Check Component Replicated
U should replicated own actor to make it work.

limpid notch Feb 5, 2019, 7:15 PM

#

what do you mean by "U should replicated own actor to make it work."?

twin juniper Feb 5, 2019, 7:17 PM

@limpid notch
Own actor is
The actor who hold the widget component.

guys i have a problem that im guessing it has to do with multiplayer. When a new client enters , onpostlogin thats fired in gamemode spawns a character at a constant transform thats being possesed by the new player. The clients have good rotation , as specified in the constant variable , except the first one , who spawns with a different rotation even though when i print its rotation , it is the same with the variable. Why is this happening?

sharp pagoda Feb 5, 2019, 9:09 PM

#

@limpid notch Any reason you're avoiding player starts?

limpid notch Feb 5, 2019, 9:17 PM

#

i want people to spawn at different locations

#

and i couldnt do that with player starts since they can spawn people at the same position

sharp pagoda Feb 5, 2019, 9:18 PM

#

No, player starts are helpers that mark potential places to spawn. It's up to the gamemode to determine where to actually spawn the player

meager spade Feb 5, 2019, 9:18 PM

#

thats not true

sharp pagoda Feb 5, 2019, 9:19 PM

#

You provide your own code to determine which player start should be chosen. (Or any actor really)

limpid notch Feb 5, 2019, 9:19 PM

#

ok idk why i haven't thought of that let me try it

meager spade Feb 5, 2019, 9:20 PM

#

we have a ring of PlayerStarters, and we assign a player to one of them in the gamemode, and we assign to the first one, then the second etc. If your doing it randomly, best to mark if a playerstart is occupied

limpid notch Feb 5, 2019, 9:20 PM

#

for some reason i gave up on player starts pretty easily thinking doing the other method was more ok

sharp pagoda Feb 5, 2019, 9:20 PM

#

Yea no player starts are usually the way to go

What is the proper way of showing a loading screen that works for both open level and seamless travel?

seamless travel is a pain but openlevel is doable

vital steeple Feb 6, 2019, 2:31 AM

@halcyon abyss maybe this is jenky but after open level, if its successful i just have it clear the HUD and load a widget that has an animation and loading text. works fine for the short term to let folks know they successfully connected and are loading

that only works from server join though

how do you guys handle friendly fire filtering? do you filter before you fire the interface or do you catch on the receiving actor?

i have a working system that catches on the sender, before calling the interface, but setting up the casting on everything gets kind of clunky

Quick Tip
To make downloadable content for yoyr project just follow this steps:
1-enable Allow ChunkID Assignment in Editor Prefernces->Experimental
2-enable Generate chunks and build Http chunk install Data in Project settings-> Packaging.
3-right click on content you want it to be downloadable
4-select Asset Actions-> Assign to chunk
5-give it an Index(example: if you assign a cube to index 1 and assign a red material to index 1 too, the cube and material will be on the same chunk)
6-package yoyr peoject from File->Package project.
Note: if you want to download and use the downloaded content just use Request Content Node and Mount (it is work for mobile and pc)node on yoyr project before you package the project

#

Btw yoyr == your. Sorry

Quick tip:
There is three reasons for Lag on online games:
1-your internet speed.
2-(servers speed)the speed of data transfer on servers.
3-the speed of data transfer on your router (on lan games only).

#

@humble comet
Hello
Which online subsystem you use ?

humble comet Feb 6, 2019, 12:18 PM

#

@twin juniper i am not using any(should I? 😅 ), I have added online subsystem null in default engine ini though

twin juniper Feb 6, 2019, 12:22 PM

#

@humble comet
If you want your game to be avaliable on the internet you should use steam, or any other online subsystem services.
For lan games you should use Null in .ini
So if you use null on your .ini
First when you open the level
Force engine to use lan by this command after creating the session
open LevelName?listen?bIsLanMatch=1
When you want to join session
Just use the normal join session node
NOT open [ip]

humble comet Feb 6, 2019, 12:26 PM

#

so in order to test current setup (Dedicated server on internet ) what options do I have except steam subsystem

winged badger Feb 6, 2019, 12:30 PM

#

if you run your dedicated server in a VM on same PC

#

its unlikely that its exposed directly to the internet

#

as long as its behind a router, you have to handle that by either using a service that does NAT punchthrough for you, or by setting up port forwarding

humble comet Feb 6, 2019, 12:34 PM

#

well I have setup windows azure virtual machine for dedicated server, so its not running on my local pc

@twin juniper your setup is for listen server, with lan or steam. Issue is I have already running headless dedicated server on the internet hosting, so I want clients to connect to that server

twin juniper Feb 6, 2019, 1:00 PM

It is work for me for all

#

Also this work for all not for steam only..

jade gazelle Feb 6, 2019, 1:25 PM

#

You shouldn’t need sessions or online subsystem for what you are attempting to do @humble comet

#

It sounds like the issue is what Zlo said, something with port forwarding or NAT punchthrough

humble comet Feb 6, 2019, 1:26 PM

#

yeah, maybe azure is blocking some incoming traffic through port

jade gazelle Feb 6, 2019, 1:27 PM

#

I haven’t used azure before but it should be basically the same as any other service to set up port forwarding

#

Online Subsystem is used for just what it says, subsystems. It sounds like you are just trying to directly connect to a master server right?

#

That’s different than find/join sessions

Does anyone know how Epic Games tested Fortnite Battle Royale for performance stuff etc.? Did they actually need 100 people to test at once for it or is it possible to somehow simulate that large amount of players ingame?

You do need 100 players at some point

Indeed, but for my game we want to see how performance is before we do anything

bitter oriole Feb 6, 2019, 2:16 PM

#

Performance is going to depend on the game

thin stratus Feb 6, 2019, 4:13 PM

#

@humble comet @twin juniper Sessions make 0 sense in what they want to do.

#

Sessions require either LAN or a MasterServer(Steam or similar Subsystem).

#

Since they said "no steam subsystem", Sessions over the Internet won't work.

#

You are only left with direct IP Connection.

#

Which requires the PC (or whatever you host the DedicatedServer on) to have the 7777 port open etc.

night jay Feb 6, 2019, 5:13 PM

Open menu map then destroy session

icy nacelle Feb 6, 2019, 7:32 PM

#

This is where I was confused, will destroy session just run on client then?

Hi! Network replication of a custom made raycast vehicle (BP based). Ideally the physics should run on each client and the respective position / rotation / velocities (linear and angular) replicated to the other clients. Any pointer to where I should start looking? Everything I find talks about server to client. Tnx!

#

This is the baby I wish to replicate

i dont think you can send things from client to client w/o the server being the middle man first

#

unless of course you extend the engine one sec i got a link for something though

urban palm Feb 6, 2019, 9:23 PM

#

Yes. I am OK with the server being the middle man but I don't think that running the physics on the server is an option.

#

i believe that this is still relevant, someone can correct me if im wrong

#

but autonomous proxy would be what you want

#

which is automatic with pawns

urban palm Feb 6, 2019, 9:25 PM

#

Udk as UE3? 🤔

dusky flower Feb 6, 2019, 9:26 PM

#

yeah its a generation back but im pretty sure most of it still applies

#

you just set your role on the client to simulated proxy, or it should be that automatically, and it will do client side physics

urban palm Feb 6, 2019, 9:26 PM

#

So how is that supposed to work? Each pawn (car) sends its position / rotation / velocity / angular velocity to the server and the server replicates that to the other clients?

dusky flower Feb 6, 2019, 9:27 PM

#

"Pawns are one of the most complex actors in terms of replication, because of their need for client side prediction, yet inherent unpredictability in their movement. There is no way to duplicate this behavior except by subclassing Pawn, so don't expect to achieve it in your Projectile subclass. It gets velocity updates for the client side prediction, while at the same time getting location updates from the server to 'readjust' the player's locations."

#

that's simulated proxy

#

"This is used for you. When you play online, you yourself should be treated differently from all other PlayerControllers. You don't want your own self being predicted based upon the server's expectations. Rather, you want to control yourself and tell the server where you are moving. That is the purpose of this role. This is used for things that the client directly control."

#

thats autonomous

#

autonomous is for your player controlling the object, so the client isnt extrapolating stuff

urban palm Feb 6, 2019, 9:29 PM

#

Ok makes sense. How about collisions?

#

Between the local client pawn and the replicated ones?

dusky flower Feb 6, 2019, 9:30 PM

#

that should be predicted with server correcting the collisions afaik, but if you have faster netplay you might want to update bUpdateNetFrequency

#

each actor has that bool btw

#

same with Role and RemoteRole (bitmasks)

#

like simulated proxies are default for the role of things, and physics and stuff is predicted on the client

urban palm Feb 6, 2019, 9:33 PM

#

I think I need to look more into this proxy replication. So the server will keep a proxy of each pawn, run some prediction and then redistribute it to each client.

wary willow Feb 6, 2019, 9:33 PM

#

@urban palm TBH, you'll probably need client-side prediction for that

dusky flower Feb 6, 2019, 9:33 PM

#

its just the name of each ENetRole

urban palm Feb 6, 2019, 9:34 PM

#

So I would need to predict in each client how the other clients are moving?

#

Based on what I get from the server?

#

So the collisions would be handled locally in each client.

unique thunder Feb 6, 2019, 9:35 PM

#

Any Gamelift users here?

#

@urban palm Haven't read through to find the full problem with your case but look into 'Smooth Sync', a plugin on the marketplace. I was having problems with replicating physics and it helps keep clients in sync better than I expected.

#

I actually got it because my vehicle's rotations were being corrected constantly by the server and they ended up very jittery.

urban palm Feb 6, 2019, 9:38 PM

#

Thanks, I will look into it even though I would prefer to solve it without plugins if possible

unique thunder Feb 6, 2019, 9:38 PM

#

Stock vehicles in UE aren't very good in networked scenarios -- at least not without modifying it in the backend

#

Learned the hard way

dusky flower Feb 6, 2019, 9:39 PM

#

yeah apparently ue4 only has client side prediction for UCharacterMovementComponent through the INetworkPredictionInterface implementation

#

and UWheeledVehicleMovementComponent if you are using that

urban palm Feb 6, 2019, 9:39 PM

#

@unique thunder I have an own vehicle implementation, it's not the stock one.

#

Posted a sneak peek above.

unique thunder Feb 6, 2019, 9:40 PM

#

Sec

#

Oh damn that looks like fun. I might loosen the camera up a bit to let the car get away a bit more but that might be cool as an option (personal preference). I don't know anything about physics replication in C++ but it might be worth taking a look at the C++ code in the smooth sync plugin to see how they interpolate the car's transform and keep it in sync across all clients.

urban palm Feb 6, 2019, 9:43 PM

#

Tnx! The vehicle is all BP at this point. I was wondering if I could manage the replication without going to C++. Mostly for didactic purpose. But I will if I have too.

unique thunder Feb 6, 2019, 9:45 PM

#

The frontend replication settings don't help much with keeping vehicles in sync, that level of precision isn't something I was ever able to achieve at least. Aside from client's vehicles stuttering (though mine was in VR, players were attached to cars and not in control of them as playable vehicles), I also noticed a lot of desync where cars would be seen driving in different directions on different clients, or one client would see it flipped upside down and another client would see it flipped sideways etc.

These might've been problems in my workflow but whenever I tried to find solutions, I was always told that the frontend doesn't offer much for networked vehicles in general.

urban palm Feb 6, 2019, 9:49 PM

#

@dusky flower Thanks! Will read through it. My idea is to have each client run the physics of its own pawn (car), then send its location / rotation / linear velocity / angular velocity to the server. The server redistribute it to all the other clients and each client creates a local copy of all the other cars which are just rigid bodies with collisions + visual wheels

#

Not sure that is possible though.

#

Let alone all the anti-cheating stuff which I don't need anyway at this point.

dusky flower Feb 6, 2019, 9:51 PM

#

yeah, ue4 has a way to check for cheating built in, so you have that for later. but client-side physics to server seems possible from this post

#

would be nice to have staff chime in on this

urban palm Feb 6, 2019, 9:55 PM

#

Yes, I would be cool to get some more guidance on this.

#

Quickly reading through Rama's post above it seems that the proxies are actually on the server.

#

The server does the prediction and reconciliates it with the actuals from each client, then passes the results back to all the clients.

dusky flower Feb 6, 2019, 9:59 PM

#

it would be an "autonomous proxy"

#

which is like player-controlled

#

you can run functions on the client

urban palm Feb 6, 2019, 10:01 PM

#

So to recap:

Each client runs its own physics (own car)
Sends the location / rotation / linear velocity / angular velocity to the server
The server uses that information to update the prediction on the proxies it is keeping (one for each client)
The server passes back the information from the proxies to all the clients
The clients use that information to update the position of each other client's car
If there is a collision, each client handles it locally and that reflects back to the server when the new location / rotation etc. is passed to it

#

I need to find a way to test whether this will work before attempting a full implementation...

@dusky flower Thanks! Trying few things out at the moment, but the client doesn't show up.

#

#

I guess there is a collision on spawn which cannot be resolved

dusky flower Feb 6, 2019, 10:10 PM

#

im guessing its the camera?

#

looks like the camera might be inside of something, try putting the player spawn point up in the air

urban palm Feb 6, 2019, 10:13 PM

#

Solved by placing 2 Player Start in two different locations

#

The server car replicates properly to the client, but not viceversa, as expected

#

The server has an own copy of the client's car which follows its own logic

dusky flower Feb 6, 2019, 10:16 PM

#

your movement code might need to be setup for multiplayer

#

you could probably just do UFUNCTION(Server) over the functions that do movement

#

but the function definitions are different, youll end up needing funname_Validate and funname_Implementation as definitions

urban palm Feb 6, 2019, 10:19 PM

#

Got it.

#

Now it doesn't spawn the client anymore. Something is off...

worthy perch Feb 6, 2019, 10:19 PM

Why not just copy CMC?

dusky flower Feb 6, 2019, 10:20 PM

do your actors have isreplicates = true

urban palm Feb 6, 2019, 10:20 PM

@worthy perch I am looking into a simple implementation from scratch
