multiplayer

[dark edge]

Your question doesn't make much sense. You can get the game mode, and cast it to your specific game mode subclass, if you're on the server. On client, Get Game Mode will fail because the game mode doesn't exist on clients.

[real ridge]

weird i had cast to game mode in client and it called function succesfully but now when I closed editor and started it it got stuck at 75% loading -_- and i figured out its because of playerpawn where was this cast

so it messed up something

[real ridge]

I can cast to game mode from player state?

i need somehow call game mode function from client

[dark edge]

Do you know what casting is?

read my name

[dark edge]

In PlayerController or Pawn or maybe Playerstate:
Entry -> Run on Server Event -> (now you're in the server's version of the object) Get Game Mode -> Cast to YourGameMode -> Do the thing

[real ridge]

via cast I can call function what is placed in game mode

right? 😄

[dark edge]

You need a run on server event between the clientside stuff and the serverside stuff

run on server event is the ONLY way to tell the server anything

[real ridge]

i know

i was doing it like this

idk why its crashing....

[dark edge]

just show your code

[real ridge]

cant load

[real ridge]

unfortunately i cant show u code as my game with current code cant run... I need revert changes and make it again

well 2 hours of work are in bin

[dark edge]

First of all GameMode shouldn't be storing PlayerWithBomb

[real ridge]

it isnt

[dark edge]

According to that code it is

[real ridge]

I have ?bomb bool in player state and game mode just go through all controllers and check if they have bool is true

if it is its found it

[dark edge]

Just have PlayerWithBomb be a reference in GameState (if other ppl are meant to know it)

[real ridge]

i remade it already

[dark edge]

no need to loop or whatever

[real ridge]

but still dont understand why if I have bad cast or code editor wont run .... fk why it just cant throw error when trying to play

but no it wont run editor at all..

ah

i need now remake it

[dark edge]

What are the general rules for your game? A player can have a bomb. What else are the mechanics?

[real ridge]

this is video what it did dont look at movement its broken now

and I stopped it at the end to see

i take bomb and then after countdown it will take damage to the base which is nearest

to the player who has bomb

but i cant anymore run that game as its at 75% vcs of bad cast

😦 i am going to do it from scratch

[worn steppe]

I have a RPC marked as Client that is only invoked from the server, and inside this client RPC I draw some debug text and set some HUD text. I only see the HUD text on the client that I expect to, but the debug text is drawn on all clients. it's a 2 line function, the first line draws the debug text, the second line sets the HUD text. this makes absolutely no sense to me? surely it should only be drawing the debug text on the client that its updating the HUD text on?? can anyone explain this magic

[dark edge]

I'd do it like this.

In bomb actor:

Event Overlap -> if has authority and other actor = Airplane or whatever -> Attach to OtherActor -> Disable Collision -> Timer/Delay -> Destroy closest base

No need for gamemode or gamestate or anything like that.

It's that simple

DestroyClosestBase can inform the gamestate or gamemode if you want for scorekeeping etc

[real ridge]

i dont want destroy just take like 200 damage

[thin stratus]

You mean actual debug screen stuff? Might be a Single Process editor stuff?

[dark edge]

well you get the picture. Let the bomb do the bomb stuff, no need to involve Gamemode or Gamestate etc.

[worn steppe]

GEngine->AddOnScreenDebugMessage - like this?

[real ridge]

my bomb now

[real ridge]

i am using also game mode to countdown

[thin stratus]

Yeah just check if the same happens with proper standalone setup

[dark edge]

That can work but I'd do all the bomb mechanics inside the bomb

[real ridge]

like this

[thin stratus]

Pretty sure onscreen debug is showing on everyone due to the single process

[real ridge]

going to try

[worn steppe]

Ahh, will try

[real ridge]

but i cant because after I pick bomb its get destroyed I call destroy actor and then I cant do any more code inside because its already destroyed

thats why I did stuff after countdown is 0 in game mode

[dark edge]

just don't destroy it

let the bomb do the countdown

[real ridge]

whyy

but when I pick it I cant see it anymore

[dark edge]

I mean it's a matter of taste but that's how I'd do it

[real ridge]

its picked

[worn steppe]

oh boy, lots of things break if it's not a single process. this is not good ^^

[real ridge]

what if i tried make logic in player

who took bomb?

hm

can work?

[dark edge]

Why? Would you put gun logic inside a character or in a gun actor?

Why not put all the logic for everything including the airplane flight inside the gamemode

lol

[real ridge]

because BOMB will be destroyed after picking

i dont want to see it on map anymore

its like collectible

[dark edge]

Just don't do that. Turn off collision, set it hidden, attach it to the plane that picked it up.

[real ridge]

hidden means i wont see it ?

sorry for dumb question how to attach XD

[dark edge]

I'd do the item logic inside the item, then it'd be trivial to make a new item like one that you can pick up that'll heal the closest base. You'd just change a few values and voila, it'd just work.

all up to you tho

[real ridge]

ok i will try but another question i do have this timer which is running when it is 0 i should call event from bomb but can I cast to it from widget?

[dark edge]

Widget should just SHOW the timer, not define it

timer lives on bomb as a replicated variable I'd say

[real ridge]

nope i am calling countdown function to game mode from bomb after picking and then in game mode calling it on all clients and then widget has timer itself

[real ridge]

also this was problem for me how should bomb make count down i can multicast widget of count down to others?

i thought its not good solution so i used game mode to it

[worn steppe]

argh, I've been using things like GetLocalRole() == ROLE_Authority and only running client side actions if that is not true. I've been testing as Play As Client. guess whos listenserver does not work at all

[real ridge]

okay i did it like you said but i dont know how to multicast widget from one player to all or if its right so I made similar timer in bomb and set same time and both are ending together

[versed ocean]

can I remove mesh instances from server or are they literally not even known about by the server?

[dark edge]

The widget shouldn't have anything to do with the networking

UI should be local only

[real ridge]

bro but count down need to see everyone on map

if i pick bomb

then all should have 10sec countdown

on monitor

i need multicast it

[dark edge]

Bomb is a replicated actor. Bomb state has an onrep which tells every local HUD or Playercontroller to show the UI

[real ridge]

I did it like this

from bomb

[dark edge]

That can work

[real ridge]

and its only multicast as its called from remote

so its authority server

its working but I tried on another pc my project and its again 75% loading

so something is wrong there...

some cast

[dark edge]

Your code is jumping all over the place. The bomb can just multicast within itself or use an onrep

Picked up -> multicast or onrep -> get local playercontroller -> cast to yourplayercontroller -> show countdown

[real ridge]

thats what i am doing

[dark edge]

This already executes on all. Just get local playercontroller. No need to loop or do any other network stuff

[real ridge]

last thing I need is when I kill player who "has" bomb and kill him bomb will drop on his position and prepared for picking

[real ridge]

i will try

are you sure ?

[dark edge]

Get what you have working first before trying to add more on to it

[dark edge]

I mean it's a multicast event so yeah it'll execute everywhere. That's assuming you've replicated the actor etc.

[dark edge]

Easy, just do the opposite of what you do when it's picked up

I'd make an OnDeath dispatcher on the pawn and the bomb binds to it on pickup so it knows when to release itself and go back to being a pickup

Or the pawn can have a variable MyBomb or MyPickup and tell it to detach when the pawn is killed. Either way.

[real ridge]

did what you said

and its not replicated

without loop

now its working I did this moved it to bomb

from controller

[worn steppe]

What is the correct way to check if execution is on a dedicated server vs a listenserver vs a client?

Checking against ROLE_Authority doesn't work because that is both dedicated and listen servers, but I don't want to allocate client-side resources on a dedicated server (e.g. a player HUD)

[dark edge]

You'd make the ShowCountdown event not an RPC

Basically on every machine, the Bomb tells the UI to show the countdown. That's it

Bomb on server:
Overlap -> Change state -> Multicast

Bomb Everywhere:
Multicast -> tell local UI to show countdown

OR

Bomb on server:
Overlap -> Change state (repnotify)

Bomb Everywhere:
RepNotify -> Tell UI to show countdown.

Either way, the ONLY networked thing is the repnotify or multicast in the bomb. that's it

[real ridge]

thank you I will continue in the morning last thing I am worried is how to pass time from bomb to widget i except i need make count down on bomb side

and just multicast value

10 9 8 7

[worn steppe]

maybe the issue is that I should be placing HUD and other client-specific stuff in the PlayerController instead of the players Character

but where is the PlayerController :x

[dark edge]

repnotify my dude

[real ridge]

i should go sleep and rest, thank you for all conversations u cant imagine how much u helping me even i look dumb every time

thank you I really appreciate your time

will continue tommorow

much love

[fathom aspen]

Well Widgets don't exist on dedicated-server, even if you try to do that you would be notified. And to answer your question, beside Roles there is NetMode

So you can check IsNetMode for example

[worn steppe]

thanks, I will keep that in mind. it would be simpler to just add some NetMode checks against dedicated server then, although I am now in the middle of moving all of the client-specific code to PlayerController. granted, I haven't fully figured out how that will fix the problem yet, so I might end up needing NetMode regardless?

[fathom aspen]

What do you mean by the client-specific code?

[worn steppe]

things like, displaying "Press [Action Key] to Interact" on screen

[fathom aspen]

PlayerController would have code that naturally belongs to it

PlayerController is like the interface between the human player and in game player

[worn steppe]

I'm just trying to leverage the fact that the client owns PlayerController

so maybe I'm doing a dumb thing

[fathom aspen]

You could look into the engine source to see what is there already to get a better feeling of what should exist there

[worn steppe]

that is a good idea

[fathom aspen]

For example I wouldn't have HUD stuff in PlayerController

HUD/Widgets exist inside HUD class

HUD is a good manager for Widgets and is also easily accessible from PC

[worn steppe]

for some reason I was discouraged from using the built in HUD functionality, so I've just put it into the character since that was easy

probably dumb in hindsight

[modest crater]

HUD is a fantastic place to put that stuff but in lyra UE is starting to move awway from the HUD class idk why

[fathom aspen]

Also to answer your past question, you don't really need to check against NetMode to make sure you're not on dedicated to be able to add widgets safely. You can for example mark your UFUNCTION with BlueprintCosmetic and it won't run on dedicated

[worn steppe]

oh

[fathom aspen]

Yeah Lyra is changing all the standards

But I wouldn't take Lyra as an example to build on when I'm solo deving

It's meant more towards AAA teams tbh

[modest crater]

ahhaha

I was wondering

[fathom aspen]

I miss Laura

[austere burrow]

Hey all, I'm having a strange problem. When I change input modes from UI to Game on client the E key (which is my UI confirm key) does not work on first press, but then works normally. For the host (listen server) there is no issue. I'm using Common UI and enhanced input. Any help is appreciated - I'm not even sure where to start

Key events are all local so idk what might be causing the discrepancy

[glass vector]

how do you check the android packaged version number in your game in BP?

i want players to not be able to join multiplayer rooms if their packaged version number does not match

[short arrow]

they left the server?

[worn steppe]

Okay, I think I figured it out finally. All I need to do is check if a character is controlled by the player controller, and if so then run the logic of adding the HUD elements

Question is, how do I compare instances of ACharacter against one another?

wait so the character isnt even possessed when BeginPlay is called. oi. at least PossessedBy() should work

[steady nimbus]

Hmm I'm having quite an issue with ServerTravel, I tried to read all the docs I could on it but...

1. I use GAS for all my stats/abilities and I believe everything is correctly replicated
2. I have this inventory component on my PlayerController - when you pick up a weapon it goes into the inventory and this is all replicated and other clients can see the equipped item on the player and whatnot

The problem is when I use seamless travel, it does not seem like my PlayerControllers are persisting and the pawns are completely reset (as is the inventory)

however, I've already double checked that I have a transition map and seamless enabled across all my gamemodes (but I'm using all the same game modes)

[fossil spoke]

PossessedBy does work. Its Server Only IIRC.

[steady nimbus]

Do I really need to move my inventory system to PlayerState and then do CopyProperties kinda stuff?

[fossil spoke]

You should be using the AHUD class to initialize HUD Widgets.

[fossil spoke]

The PlayerController also has a similar CopyProperties function like the PlayerState. However i cannot remember what its called.

[worn steppe]

would that include functionality for playing local interface sounds and things

rather, is that where you would put that kind of functionality

[fossil spoke]

If a UI element needs to produce a sound, that element or its parent should be triggering it.

UI is all Client side per Client.

[edgy patio]

isnt the ControllerSwap?

[fossil spoke]

Not sure i understand what you mean?

[worn steppe]

I'm wondering if there is any other times where I would have client side behavior that should be local to a single client that isn't interface-based

[fossil spoke]

Plenty.

Anything that is Predicted is Client side behavior for only that Client.

[worn steppe]

good point

[edgy patio]

Oh forget it, there is a SwapController or SwapPlayerController but it is in Game Mode, not on the Controller class

[steady nimbus]

I was researching into that! I see that is on the game mode -- though the docs state that you shouldn't need to copy if using the same game mode....

[fossil spoke]

Generally its advisable to always setup copies anyway.

[steady nimbus]

Interesingly enough -- EventOnSwapPlayerControllers does not get called which means the PC is not actually swapping out...hmm will have to do more research

[edgy patio]

It's because that was my mistaken. I though the similar CopyProperty function that @fossil spoke mentioned was "SwapPlayerController" but this SwapPlayerController function is executed on the GameMode.

You should probably use the SeamlessTravelFrom function. This one is inside the PlayerController

[fossil spoke]

SeamlessTravelFrom is what I was thinking of that i couldnt remember the name of.

[steady nimbus]

interestingly enough https://docs.unrealengine.com/5.0/en-US/API/Runtime/Engine/GameFramework/APlayerController/SeamlessTravelTo/ I can't seem to call/find that from BP in the PlayerController lol but it does mention
not called if PlayerController is the same for the from and to GameModes

btw thanks @fossil spoke and @edgy patio for helping out* -- extremely helpful in at least diving into some of these as I was going a little crazy why it wasn't working lol (still isn't but maybe getting closer)

[edgy patio]

No problem, I'm trying to figure out how to deal a kind of similar problem

Maybe this guide can help you figure out https://wizardcell.com/unreal/persistent-data/#persistent-runtime-data

I'm not sure in your game, but I probably would make my own CopyProperties to handle the inventory data.
You could override the GameMode's HandleSeamlessTravelPlayer function to call your custom CopyProperties.

But in this way I am implying that the inventory will always exist and should be persistent, otherwise you wouldn't Copy anything and you would lose your data

[near granite]

I want to replicate the movement of actor, In the blueprint of this actor, I add the "switch has authority" macro so that i can run this code only on the server in order to replicate..

Am i doing right??

[worn steppe]

you know, I guess this makes sense, but I just now realized that repnotify variables do not call the notify function on the listenserver, but that is kind of annoying

been going crazy trying to debug that

[kindred widget]

Generally you don't really want to call OnReps on server code. If you need to do the same thing in server and client code, you make a new function and call that from the setter and the OnRep.

It makes debugging replication stuff a lot cleaner because you can know easier if you're actually getting onreps on the client and can run through the callstack easier with a breakpoint in the server setting code or the OnRep to know if you're on client or server.

The Blueprint style of calling OnRep on the server automatically is generally frowned on.

[worn steppe]

Good to know, I don't know anything about blueprint logic really

[near granite]

Is the repnotify function unconditionally executed as multicast?

[worn steppe]

DECLARE_DELEGATE_OneParam(DelegateName, Param1Type) it is safe to pass one of these as an RPC parameter, right?

[winged badger]

No

There is also no point passing delegates

[worn steppe]

hm ok

[winged badger]

There is a difference between bp and c++ here

You should think of blueprint onrep as property changed, not replication callback

Because that is exactly what it is

[winged badger]

Only dynamic delegates can be serialized, but even they cant convert object pointer to netguid iirc

[worn steppe]

I think it will be OK to just use the delegate and then invoke an RPC afterwards

honestly, I have no idea though

[winged badger]

Delegate basically comes to invocation list of functions

[worn steppe]

yeah, I just wanted a callback function basically

[winged badger]

That doesnt translate well over the network

You have delegate as a member in dame class as rpc

You have each machine bind their handlerd locally to it

Then you rpc just broadasts delegate member

[worn steppe]

it's just tricky since sometimes a server is a client, sometimes it isn't, and I have no idea anymore when what is executing where

[near granite]

I did like this...

[winged badger]

Mobile, cant view screens really

[near granite]

If I move the project to another computer, do I have to redo the dedicated server build as well?

[latent heart]

Not if you also moved the dedicated server.

[near granite]

but i have this error " Client target not found"

[winged badger]

Server rpc called from listen server host is just a normal function

That gets executed normally

[near granite]

Thank you! I selected the unreal client botton instead of the botton of unreal game!

[near granite]

There is no tag but only component tag.
Can i use component tag as same concept when i use tag?

[real ridge]

is it possible to cast from repnotify to widget?

where I want change value?

[kindred widget]

You call delegates. Widget should be bound to them. Gameplay classes should have zero reasons to ever have a pointer to a widget.

[near granite]

When RightGrip is input, the repnotify variable R_Rock becomes true, and when R_Rock is called, the repnotify variable of BP_Pulse becomes true.
START changes to True, and then I made the code like the third picture run, but it doesn't work,,,Could you give me some advice?

[faint parcel]

Is it true that with DOREPLIFETIME(Class, Array) changes to the array elements (using a pointer or reference) doesn't trigger OnRep_ methods to be called? But if using DOREPLIFETIME_CONDITION_NOTIFY(Class, Array, COND_…, REPNOTIFY_Always) changes to the elements to trigger OnRep_ methods on clients (like the user writes here: https://forums.unrealengine.com/t/repnotify-for-arrays-not-triggered-when-modifying-a-contained-value-by-reference/117036/2?u=aperfectmisterman).
I have been foolishly making changes to elements in a TArray of USTRUCTs (mutable structs, buuuh!) and having problems with replication. Is this the reason?
I think I will move to just assigning new elements to the TArray to avoid using mutable structs, should fix the problem as well, right?

[real ridge]

guys I am trying to remove widget by multicast when I start new countdown but I still have both there I am just using remove from parent on multicast.. 😄

trying it like this but not working

[kindred widget]

Don't mix execution lines like this. Save the widget into a property, and use that to remove it.

[real ridge]

i saved it and also didnt help

when I tried use remove all widgets

it worked

but I deleted all

i need just that one 😄

[kindred widget]

Sounds like you have created too many and are only removing the last created one.

[real ridge]

I am creating on all clients

and also I need remove on all clients

here I am creating it

I am trying to add there remove from parent

before add to viewport

but no effect

weird

[kindred widget]

Where is this multicast broadcast from?

[real ridge]

from has authority line

so its server calling multicast

[kindred widget]

What on the server calls it?

[real ridge]

remove ?

[kindred widget]

The Multicast.

[real ridge]

that multicast is connected to this authority

[kindred widget]

What calls that though?

[real ridge]

i dont get your question sorry

wdym

my english is weak 😄

[kindred widget]

What is the event to the left of the HasAuthority?

[real ridge]

actor begin overlap

its bomb picking

so I am doing it on server

so noone can cheat

but remove from pparent should work

after multicast....

[kindred widget]

Quick dirty check. Put a DoOnce before your CreateWidget node. And try it again.

I'm assuming something is calling your ClientsCountDown multicast too much and you're not checking if the widget is already created and on screen. Possibly leading to multiple widgets that look like one. So RemoveFromParent is only removing the last one.

[real ridge]

weird result

second countdown didnt even start

bcs of do once

[kindred widget]

Try this then in your multicast. It'll only create your widget once. And will not try to add it if it's already in the viewport.

[real ridge]

ah I am retard I first need solve how to sync time because now I have timer inside bomb and also own timer inside widget both have time 30 sec but its not synced I should set timer from bomb and do not let widget to count

its foolish solution

[real ridge]

thx

[faint parcel]

I'm replicating some teams structs, but the PlayerStates that I use to refer to players are nullptr on the client. I assume this is because playerstates are not yet replicated at that point?

[fathom aspen]

Prolly. They take more time to replicate than other actors

hi

[gloomy tiger]

Hey guys - does anybody have an article or reference related to how UE serializes variables before dispatching them through the network?

I'm more curious about fstructs specifically, but anything helps

[twilit radish]

It's just a stream of bytes per certain 'action', those streams are referred to as "bunches" within the Unreal source. Then actual packets contain those bunches, whether that's one bunch, a part of a bunch, multiple bunches or a combination of all of that. Serialization depends per specific object on how it's done, a Vector does it different to for example an entire struct. You might be interested in reading this as an example if you have source access: https://github.com/EpicGames/UnrealEngine/blob/release/Engine/Source/Runtime/Engine/Classes/Engine/NetDriver.h#L187-L218

Structs in specific if you don't do anything else than marking things as a UPROPERTY and mark that struct as replicated somewhere within an actor will use 'Delta Serialization', which I suck at explaining lol. If you use a custom net serializer within C++ you can disable that behaviour. But that's something you need to explicitly do.

[gloomy tiger]

Hey @twilit radish - thank you for your inputs. All of that was helpful. 👍

[prisma snow]

I think it is also possible to 'customize' how a struct is serialized by implementing one function (forgot the name)

[crystal crag]

Is it possible to use duplicate player names when calling NewController->PlayerState->SetPlayerName(...)?

For example, I spawn three of the same monster AI class and I want them all to be called "Muffin Monster 1" - would I be able to call NewController->PlayerState->SetPlayerName(FString("Muffin Monster 1")); for all three or would that cause problems?

[latent heart]

Probably yes (it would work)

[plain gust]

When user join in Session and executes UpdateSession() in PostLogin(), Session is not found in FindSession()
what's the problem?

[quartz iris]

How can I make the other player see what costmetics you have? As the client only sees their cosmetics on the other player

The costume is selected by the player using enums

[prisma snow]

Just a sanity check - if I ask for HasAuthority() in the Player Controller, it will only return true for the clients or, in the case of a listen server, for the PC of the listen server player, right?

I'm doing some client-only setup that runs on info from GameMode so

[twilit radish]

HasAuthority() checks if the local network role is the authority. Which for a player controller is only on the server.

[prisma snow]

ok then I was doing it reverse xD

[graceful flame]

This is the updated version of that diagram with Game Instances

[prisma snow]

Then, for some code to run on the client version of the PC, I have to check that it does not have authority

But then it is possible that the listen server doesn't work properly

[twilit radish]

Correct, listen server will then break.

[prisma snow]

This are not RPCs

[twilit radish]

You don't have to run it as an RPC. IsLocalController can be used for the client.

[graceful flame]

oh for listen its different

[prisma snow]

Ahhhh will that work for ListenServer as well then?

[twilit radish]

Yes, it checks if it's locally 'controlled' aka will only run whenever it's the client or the listen server but only for their own controller.

[prisma snow]

Excelent that's what I need

thanks

fingers crossed I fix this bug finally 😄

[ember furnace]

Hi, i have problem with multiplayer event replication, i have 3 clients, client 1 and 2 are working as intended, but somehow when client 3 is posting message server side event wont fire(ServerSendMessage event), even if local event fire (SendMessage)
i'm using option to play as client, dunno why 1 and 2 client works but third one don't

[twilit radish]

How are you getting the PlayerState for 'SendMessage'?

[ember furnace]

From widget

This part in widget fires as expected, then in player state it fires local event and then server event but only for client 1 & 2, on client 3 it does nothing

also in 4 clients scenario: client 1 2 and 4 is working just fine

[twilit radish]

Can you instead of the Get Player State node try this?

[ember furnace]

it worked, but why?

[twilit radish]

My guess would be because Get Player State with the argument 0 grabs someone else's PlayerState. That method internally just picks the first item inside the Player Array that the Game State stores and grabs the player state. I don't think that one necessarily has the correct order because people can login at any time in any order. Which seemed likely to me if the network call failed because you can't call methods from an actor on the client which that client doesn't own.

[kindred widget]

GetPlayerState(0) will just return the first player who got put in the Gamestate's PlayerArray.

[ember furnace]

thanks for help, back to learning magic world of networking

[quasi tide]

Trying to get other clients to play the ADS animation.

Player replicates its current state (Aim, Walk, etc..), in animBP, I check that the state is Aim. If so, I blend in the aiming animation. Otherwise I don't. Works correctly locally and the server can also see it. However - other clients cannot. I have confirmed that the true branch fires off. Any ideas?

[twilit radish]

What's beyond the true though? If that does fire something else must be messing it up I guess.

[quasi tide]

Just the lerp to smoothly go between animations

It does fire off

[dark edge]

Show your code for selecting the costume

[prisma snow]

Is the standalone play mode "safe" for testing multiplayer, in the sense of being very close to two real players from different computers?

I'm testing something that doesn't work in PIE (due to shared render target that should be different for every process) and it's not working in standalone, and idk why

[quasi tide]

See - true branch plays. Top right is client 2, middle is client 1, and the ABP is showing the route of Client 2, from the perspective of client 1.

So they SHOULD be doing the animation

[quartz iris]

The event is called at the start of the game (when the map loads)

[dark edge]

Don't store the costume on the game instance

Or rather

you need to get the costume from game instance, pass it to server, and set a replicated variable

then the repnotify of that variable is where you'd actually apply the costome

[quartz iris]

Where to?

The gamestate?

[dark edge]

.

Client tells server which costume it has
Begin Play -> Is Locally Controlled? -> get enum from gameinstance -> run on server event

Server tells everyone which costume to use for this character
Run on server event -> set MyCostumeEnum(replicated, repnotify)

Everyone applies the costume
RepNotify -> actually set costume on mesh

.

Client passes costume enum to server which sets a replicated variable and everyone uses that to show the right costume for that character

[quartz iris]

Could I not just set the variable as replicated?

[dark edge]

You do, but that can only be set FROM THE SERVER

[quartz iris]

The ones in the gameinstance

[dark edge]

do you want each client to say which costume it has?

[quartz iris]

Yeah

[dark edge]

then it needs to tell the server which costume it has. Step 1 in what I posted

the server has its own gameinstance and knows nothing about the clients gameinstance unless told

[quartz iris]

Idk it seems a lot of work to have to save/load the variables in the client side variables then have another one for the server for each variable

[dark edge]

welcome to #multiplayer

[quartz iris]

Fr dude i'm losing my shit 😭

[dark edge]

You could have a savegame or gameinstance on the server keep track of what each player has, that'd be server-side inventory basically

[quartz iris]

But i'm almost there

[dark edge]

but do what I spelled out and it'll work

[quartz iris]

Alrighty

[quartz iris]

This is all in the gamestate? Just making sure

[dark edge]

all in the pawn

[quartz iris]

Got it

[quasi tide]

Fixed my bug. Was something else. I was returning early in my OnRep in C++ that would execute a delegate that provided important information. So, bug was a delegate wasn't being executed due to exiting too early.

[dim trail]

should i be binding delegates on the server or client?

[fathom aspen]

No definite answer. You bind them where you need them to be fired/called

[quasi tide]

Hmmm - what could cause a widget to not show after doing a seamless server travel? Can't track down why my pause menu does not show up anymore after traveling.

HUD begin play calls Remove All Widgets to be safe. For w/e reason - it's being really weird about the 2nd branch statement. Claiming that it is active, even though it isn't.

[abstract pike]

Just in case this is useful to anyone out there who is using replication graph and wondering why their non relevant actors are replicating when multicasts are called. There is a map where you can set the default behaviour for multicasts and whether they open channels or not. The actor is set to true by default meaning it will open a channel for a multicast. If you want to stop this behaviour you need to add this inside InitGlobalActorClassSettings.

[quasi tide]

This is what the IsPauseActive function does. It is reading it as a valid object after seamless travel. And this even happens if I never even create the widget. So weird.

Alright - this part of the HUD is all jacked up after doing a seamless travel.

Wait - so BeginPlay doesn't get called on seamless travel? (for PC)

[hollow eagle]

no, actors retained during seamless travel won't have beginplay called again

BeginPlay gets called when the actor is spawned. An actor that still exists from seamless travel isn't newly spawned.

[quasi tide]

Well - that explains my funkiness most likely. Must still be holding on to some garbage references.

Yup - that was it. Glorious

[quasi tide]

@dull lance Yeah - I know. It gives you the controller that is travelling though. So I'm doing a client RPC on that.

controller->clientRPC()

Well - I answered my own question. This is in the base implementation for the method. So it should be good as long as super is called first.

It's 578 for me 🤔

Well - it should be safe. Because HandleStartingNewPlayer is after PostLogin (I know PostLogin doesn't get called for seamless) and PostLogin is first place it is safe to do RPC

This is the bottom part of the function.

Won't be for a few days until I can properly test it working in a real-world online scenario though.

@dull lance My idea was to do this pretty much. Have a way to reset things on the PC itself. Instead of only having the methods in the GameMode. So far, this works in packaged singleplayer. Will let you know in a few days if it works multiplayer. That's when we're doing our network playtest.

[gray holly]

Hi, I'm trying to get the multiplayer example from this documentation: https://docs.unrealengine.com/5.0/en-US/multiplayer-programming-quick-start-for-unreal-engine/ to run

I just want to see step one work and see 2 players in the same game

Following the instructions just starts 2 copies of a single player thirdperson game example

[kindred widget]

You likely didn't set the PlayNetMode to ListenServer

[sonic python]

Hey Guys

In Mobile

Create Session Is not working

https://media.discordapp.net/attachments/221799385611239424/1068189528948486185/image.png

This is my Bp codes for this

I'm not using Any Online Subsystem Except Google

How To Fix It?

[thin stratus]

I'm pretty sure Google has non Session Subsystem

[uncut atlas]

does cross-platform automatically work for dedicated servers? like if an xbox and playstation tried to connect to the same server ip address will it work and they'll be able to play together?

[latent heart]

Should do, I think.

[uncut atlas]

interesting...

[latent heart]

I don't have access to the devkits, so it might be a case that they require specific platform-based session stuff which is incompatible somehow.

[uncut atlas]

oh ok. thnx!

[twilit radish]

I mean Fortnite, PUBG for example do it so considering that I would very much assume you can 'just' do it 😛

[latent heart]

Maybe they do it via EOS or something

Shrug

[twilit radish]

I don't see how that changes anything though. Something still has to handle different clients from different platforms if that was the case.

[latent heart]

I'm just saying that's the only potential issue... not that it definitely is one 🙂

[thin stratus]

@uncut atlas @twilit radish @latent heart UE blocks different UniqueNetIDs

If your Server uses NULL, Xbox uses Live and PS uses whatever they have, then you will not be able to join

If all of them use NULL then it would work, but with NULL you lose all other things that Subsystems offer you

That's why stuff like EOS exists and is required

it acts as a central UniqueNetID for different authentications via e.g. Steam, Xbox, PS

[twilit radish]

You don't have to use EOS for this. I totally get your point and didn't realise NULL doesn't accept the IDs, but there's absolutely nothing stopping you from authenticating people your self without EOS. Or.. Alternatively if you don't care about authenticating at all just not doing it.

But I can see how EOS is convenient to use yeah.

[thin stratus]

Yeah I didn't mean that EOS is the only solution

But EOS was mentioned

void AGameModeBase::PreLogin(const FString& Options, const FString& Address, const FUniqueNetIdRepl& UniqueId, FString& ErrorMessage)
{
    // Login unique id must match server expected unique id type OR No unique id could mean game doesn't use them
    const bool bUniqueIdCheckOk = (!UniqueId.IsValid() || UOnlineEngineInterface::Get()->IsCompatibleUniqueNetId(UniqueId));
    if (bUniqueIdCheckOk)
    {
        ErrorMessage = GameSession->ApproveLogin(Options);
    }
    else
    {
        ErrorMessage = TEXT("incompatible_unique_net_id");
    }

[twilit radish]

To be honest I should have realised this as I looked at this specific code like a whole 2 days ago 🤣

I was implementing my own matchmaker and was rejecting logins and ran into this specific Super I had to deal with 😛

[latent heart]

Ha. So I was right! 😄

[twilit radish]

Well actually, technically Unreal can do it just fine without stupid IDs 😛

😂

[thin stratus]

virtual bool IsCompatibleUniqueNetId(const FUniqueNetIdWrapper& InUniqueNetId) const { return (InUniqueNetId.IsV1() && InUniqueNetId.GetType() == GetDefaultOnlineSubsystemName()); }

For completion

[twilit radish]

Do the subsystems even authenticate with their platforms in the first place btw? Or do they just accept whatever you throw at it.

[thin stratus]

Depends on the Subsystem, but they should auth

Steam for example calls Steam_Init or so somewhere

[twilit radish]

So it's just dedicated servers that are special I suppose assuming we are using multiple platforms.

[thin stratus]

Usually yes, cause they are the middleman

But again, all clients must share the UniqueNetID type

[twilit radish]

Could override it though. But yeah.. By default that's a RIP.

[thin stratus]

It was allowed before 4.24 or so

It caught me offguard back when it was changed

But the ID is used in multiple places, so I wouldn't think it's a good idea to play with different IDs anyway

[twilit radish]

I mean there's a command to disable it if you really want to.

[thin stratus]

Yeah I just don't know the problems that could arise

And overall it's probably better to just plan ahead of crossplatform stuff

Especially with options like EOS being free

Even if you get them to connect, you still lack things like shared Friendlists etc.

There is more to it then just the server connection

[twilit radish]

But friend lists etc. are not going to work from a dedicated server either way.

[thin stratus]

Like you can't even query another profile

[thin stratus]

A game like fortnite allows meeting in a lobby before queueing

[twilit radish]

Oh you mean from like a player perspective where it's just easier to find your friends?

[thin stratus]

For example

You also can't really query player profiles. Imagine you have a post-match list of games that were played. Outside of a networked environment.

[twilit radish]

Ah alright, I thought you meant the server accessing that and was confused for a sec 🤣

[thin stratus]

Sony Players couldn't query a SteamID profile

Na I mean overall experience

Peeps nowadays can be happy EOS exists

[twilit radish]

I mean that's not necessarily a problem IMO. Don't see why a dedicated server can't pass on stuff like profile picture or a nickname etc.

But yes, I get the general problem 🙂

[thin stratus]

Outside of a networked environment.

E.g. in your mainmenu "Match History" or so

[twilit radish]

Fair enough.

[thin stratus]

You can work around it of course by saving those things into the cloud and just given a "hardcoded" list. But it would be easier to just point to the users ID

So the Client can even look at their profile, invite them to a match etc.

[twilit radish]

It's definitely more convenient yeah.

[thin stratus]

But yeah, we are on the same page :D

[twilit radish]

Could technically do it all your self if you want to, but it's just more convenient to have EOS or whatever do it yeah.

[thin stratus]

I think the big headache that a lot of people would have is "How do I even make my own UniqueNetId with my own backend?"

Which I can't answer without looking it up either

Probably needs a custom Subsystem implementation either way

[twilit radish]

Definitely needs a custom OSS yeah. The engine depends in too many places on that interface. And honestly probably a good idea anyway if you want to swap it out xD

[thin stratus]

Would be fun to have an open source subsystem but a lot of work

Also can't guarantee it's safe, cause I'm not good with the webdev part of this

So a self-hostable

Surprising this doesn't exist yet, but I guess people are too tied in with the existing ones or just use EOS at this point

[twilit radish]

Would be fun to try it though, but I would not make it open source my self honestly. Sounds like a good way to get a bunch of people not knowing what they are doing on your github page asking constantly for support 😛

Honestly you could easily monetize this as a company:
Create the software, host it for people that want to use it and let them pay for it, create API endpoints etc. so they can interact with and you just got your own platform system.

But then again, that's basically EOS at this point I suppose. Maybe it's better suited as an open source project yeah.. 🤣

[thin stratus]

You mean Gamesparks, PlayFab, and what they are all called? :D

[twilit radish]

maybe

[thin stratus]

I would rather just make it open source and not give support beyond accepting properly discussed PRs

I don't want to earn money with it

I even have a Plugin + MasterServer sitting on some Repo somewhere

That we never released

Way too much headache to market this

[twilit radish]

🙂

Make it, open source it, ask Jetbrains for a free Rider license. Profit.

[thin stratus]

lol

We are already paying for 4 Rider licenses

We are beyond the free part ;_;

[twilit radish]

Rip.

[prisma snow]

yeah. We are integrating Valve's open source sockets for p2p since we are not using Steam

but I bet most people use the pre-made solutions like Steam or EOS, it's just way easier

[dusky yoke]

I’m setting the player’s camera location on Event Tick, and the clients are jittering around with the code activated.

I tried running the code through a custom event from server to multicast, was a small improvement but still not great. It made me think that the tick on the server might be different than the client’s - is there a best method kinda deal when working with event tick?

[sonic python]

But that can't be used to Multiplayer right?

Does Eos Online Subsystem From the Marketplace provide Matchmaking, Matchmaking server?

[short arrow]

it supports matchmaking, but I'm fairly certain you'd need your own server.

[sonic python]

Own Server?

How Should I do that?

[latent heart]

Pay money to somebody like playfab

[sonic python]

Okay Now There's a Doubt

Join session. ,create Session code is done

For that to work

[versed ocean]

https://docs.unrealengine.com/5.1/en-US/using-the-network-profiler-in-unreal-engine/ is the engine compiled with "STATS" macro defined as nonzero by default?

[sonic python]

We have to implement online Subsystem Eos

[latent heart]

Making a MP game as your first game when you don't know what a server is or where you might host servers isn't ideal.

[sonic python]

For Eos To Work We Need Servers?

Right?

[worn steppe]

can you do P2P matchmaking instead?

[sonic python]

I understand

But this isn't my first game

This is my first Mp game

[worn steppe]

I think dedicated servers are probably overkill unless your game is going to sell a ton of copies

[sonic python]

But this is correct?

[sonic python]

Now Won't Epic Online Services Themselves Won't Provide Servers?

[latent heart]

Ah. Good!

You started sensibly! 😛

[worn steppe]

servers are $$$

[latent heart]

Session / Session hosts only provide ways for people to talk/connect, not to play.

[sonic python]

So Eos Won't Provide Any Servers so Multiplayer can't happen with it alone?

[latent heart]

Correct.

[worn steppe]

it can if you have a listenserver player right?

[sonic python]

Not to Play . hmm..

[latent heart]

Sure. That's the other option. Don't have private dedicated servers. Let people host their own or use listen servers.

[sonic python]

Is it?

[worn steppe]

there are downsides to p2p player hosting but it's a looot cheaper

[sonic python]

Okayy That's what I want

[latent heart]

You only need to pay for a server if you run it. Lots of games get by with a limited number of self-funded public servers and then let people host their own.

[sonic python]

Now There's no need for $$$ thing for Listen server ?

[latent heart]

Nope. That's run by your players.

[sonic python]

Hmm Niceee

So How To Implement It?

[latent heart]

However, they aren't ideal.

They rely on players have good internet connections.

It's implemented by default. UE supports listen servers out of the box.

In fact, it actually doesn't support dedicated servers unless you download the source and compile yourself.

[sonic python]

Is it??

Okay So For Multiplayer to work in mobile after doing the codes

I just have to implement Eos Online Subsystem?

[latent heart]

A phone probably won't be able to host a server.

[sonic python]

And It would work?

[latent heart]

They will have bad internet.

[sonic python]

Now why is that?

[thin stratus]

You can host with a Phone

Just that Google has no Session stuff

That's why they want EOS

[sonic python]

Ok That Depending Isn't it?

[thin stratus]

EOS will handle the Sessions just fine, but your Phone will need to host as already explained

[sonic python]

Ok So We Just Need to Implement Eos Online Subsystem.?

[latent heart]

Sure, it's possible. Maybe they're playing at home or in an area with good connectivity. But as soon as you go through a tunnel, boom, your server is offline.

[thin stratus]

More or less, yes. EOS is a central place for crossplatform stuff.
So you also have to deal with the authentication. I can't recall what they all offer, but I'm sure there is auth via Google

So you'd authenticate with your Google Account with EOS (linking it affectively)

[sonic python]

Yeah They have to Be Online To Play Online Games Ryt? So their problem right?

[thin stratus]

But after that it should just work. I haven't dealt with EOS yet though

[latent heart]

It's also a problem for everyone connected to their server who have no suddenly been disconnected.

[sonic python]

Oh I C

[sonic python]

Oh

Ok Like Let Me Check The Steps ,.

1. BUYING Online Eos Subystem

From the marketplace

2. To Add Client ID and things.. in the dev epic games website

[verbal tendon]

2. is where you will most likely encounter problems

[latent heart]

Phone connections are just unreliable by nature, imo. They're fine for web browsing because it's a lot of discrete connections, but they don't do consistency if the phone is actually be used outside of the home.

[sonic python]

3. To Tick Online Subsystem Eos

[verbal tendon]

the process it not documented and the error messages are unhelpful at best

So the first time you set this up will be painful until you get it right

[sonic python]

4. to implement IDs and things in Project settings.

[verbal tendon]

Also be aware that you cannot release your EOS-game as a demo to the public

before epic does brand verification ONLY people added manually to your epic org will be able to use the game

that is a big disclaimer that is not mentioned anywhere

[sonic python]

Demo?

[worn steppe]

you have to buy EOS?

[sonic python]

Like Releasing the Game is a problem?

[verbal tendon]

yes like if you were trying to pitch a MP game to a publisher

People wont just be able to use it

Epic needs to do brand verification on your game/company before anyone can play the game

[thin stratus]

You don't need to buy EOS

[verbal tendon]

before that only people in your epic org can use it

[thin stratus]

What you find on the marketplace is probably Redpoints Online Subsystem Integration

[worn steppe]

ah

[thin stratus]

Which exists for free too, but then you won't get any Support

[sonic python]

Yes , isn't it I couldn't find free version,

[thin stratus]

Idk if Epich as their own subsystem by now for it, but the Redpoint one is supposedly better anyway

[sonic python]

Support?

[thin stratus]

Yeah, if you have trouble with the Plugin itself

[verbal tendon]

I recommend buying one of the market plugins. it is not worth the time to deal with EOS raw

[thin stratus]

If you don't pay for their license then you are on your own

[sonic python]

Ohk

[thin stratus]

But the Plugin has a free license if you want to test it first

at least iirc

[sonic python]

Ok so the free version can be used however we want?

[verbal tendon]

So for example, we had EOS and I wasnt aware of these limitations, so instead of being able to give the publisher a live 2P demo, we recorded a video of us playing internally and showed that off

[thin stratus]

You'd need to read up on their license terms

[verbal tendon]

Yes.

[sonic python]

Oh

[verbal tendon]

Also what cedric said

Also ... nothing is ever truly free in life

[thin stratus]

Might be that the free version doesn't support other platforms

[verbal tendon]

You either pay for it with money or time

[thin stratus]

They say "console" but not sure what that means

[verbal tendon]

Depends on what is more valuable to you at the point when you have to make the purchase

[thin stratus]

If you're a developer earning less than $30k USD/yr, a Free edition is available. Check the website to see if the Free edition is right for you.

So you'd need to pay if you earn too much either way

[sonic python]

Now What If we suddenly become a developer earning more than that?

[sonic python]

Ohk

[thin stratus]

You have to get the paid version

[sonic python]

What??

Ok So It's safe to buy the free version?

[thin stratus]

You can also do this all without their plugin, but then you have to integrate EOS yourself. Not sure how far epics own subsystem is

[sonic python]

Eos Ourselves?

How is that?

[thin stratus]

EOS is a third party library from Epic Games. The Marketplace Plugin integrates this and adds BP nodes etc.
You can do what the Plugin does yourself, but that's a lot of work and needs a good chunk of C++ knowledge

[sonic python]

Oh Ok Not That Good In C++

[thin stratus]

Yeah then you don't really have a big choice here :D

[sonic python]

Yeah

[thin stratus]

If you are serious about your phone game then you might need to invest into the plugin

[sonic python]

Yeah I'm pretty serious

[thin stratus]

You can try if the free version works for now, but I don't know if they support Google in the free version

[sonic python]

I'll Buy The Paid Vee

So After Buying it

I don't need to change any codes in the Bp right?

[thin stratus]

Can't promise

Have never used EOS or the Plugin

Might need custom Session nodes that the Plugin provides

That's up to you to research first

[sonic python]

Is it?

Oh Ok

Thanks Man

And Thanks Guys

I'll check how to do it and Reporrrt it to you

[peak sentinel]

https://dev.epicgames.com/community/learning/tutorials/Xexv/unreal-engine-experimental-getting-started-with-iris

[versed ocean]

was trying to view the packets flying around in here I dont see any actors but I know I'm getting replication working perfectly fine?

prob has to do with this stats macro not specifically called out during my engine build? shrug

[twilit radish]

So overall minor / not too many changes for free performance. I'll take it lol. Except rip replication graph I suppose.

[peak sentinel]

too bad, many network engineers I knew suffered a lot because of rep graph 🤣

another day I thank god for not being interested in low level netcode

[twilit radish]

😂

[quasi tide]

And still no TMap 😅

improve the performance, scalability, and maintainability
Until benchmarks are actually shown - to me, this is a big nothing burger.

[eager jolt]

how can I tell if the current controller is the Listen Server?

[prisma snow]

GetNetMode()

[twilit radish]

You can use the NetMode for example.

Unless you're using BPs.

[eager jolt]

im using BPs

is there an equivalent?

[quasi tide]

Check if server. Then check if dedicated server.

Wrap it in a BPFL and there ya' go

[eager jolt]

?

[twilit radish]

That one yeah, but that also triggers for a dedicated server. Depends on if you care or not I suppose.

I think also for Standalone? Pretty sure it just checks if you're not a client.

[eager jolt]

thx

its just a small game for some mates so im not bothered about that

[twilit radish]

It does yes. So it returns true whenever the current process is either the listen server, a dedicated server or running in standalone mode.

[quasi tide]

Isn't the reason they do the networked stuff through the character for the CMC is because component replication is heavier than what they are advertising? 🤔

[twilit radish]

Yes, but that's because they call a whole lot of RPCs inside the CMC. At that point it does actually matter and for a few RPCs or whatever it really won't matter. So probably why they used "relatively low" 😛

But you can still use just the actor I suppose.

IIRC every frame until 60 when it starts to combine stuff(?). If I remember what Cedric said at some point 😅

[worn steppe]

The networking model in unreal still confuses me. I thought I understood it, e.g. this function runs on the server, this function runs on the client.. but then for listenservers 😖 ?? and so you remove all of the checking to see if you are on a server or a client to make things work but now everything just runs everywhere unless you mark it with a macro to be server or client specific and thats great except then things randomly just don't work on clients and i don't know

[quasi tide]

Far easier to do these guards in C++

But you can just do the checks that I mentioned above in BP and it'll be fine

[worn steppe]

i don't have any blueprint logic

¯_(ツ)_/¯

[quasi tide]

if (GetNetMode() == NM_ListenServer)

[dark edge]

If you set it up right it should Just Work™️ in standalone, listen, dedicated, or client

[worn steppe]

yeah, I just don't know how to set it up right

[quasi tide]

or if (GetNetMode() < NM_Client) - will run for all servers/standalone

[worn steppe]

I went thru the unreal networking docs, read a bunch of the stickied stuff, thought I had it, but I don't have it

[dark edge]

You might be better off thinking in terms of authority, locallycontrolled, and neither

standalone is authority and locally controlled

listen server's pawn is authority and locallycontrolled

clients pawn on clients machine is not authority but is locally controlled

etc etc

[worn steppe]

if (GetNetMode() < NM_Client) this is the only check I'm using now

[worn steppe]

I can check for authority pretty much anywhere, but it's hard to check for locallycontrolled unless I have a character reference which is cumbersome

[dark edge]

The only things that usually would be locally controlled are pawn and playercontroller

[quasi tide]

if (GetLocalRole() == ROLE_SimulateProxy) - you are a client, EXCEPT in the case of controller/pawn. They use ROLE_AutonomousProxy for the local player.

[worn steppe]

I am going to save this conversation and go reread some of my project code, perhaps this will be useful

thanks

[quasi tide]

I used to think that the ROLE_AutonomousProxy would be applied, even for say, the weapon used by the pawn. But it did not seem to be the case the other night.

[peak sentinel]

Maybe on the long run saving bytes also help for server costs

for 100 players

[twilit radish]

Bandwidth can get expensive I would imagine with 100 players xD

[sonic python]

Guys

I think I have Set it up

But The Create Session Fails , when opened in Standalone

[winged badger]

CPU tends to be worse

[winged badger]

Subobject replication is really expensive, yes

[quasi tide]

Does PostNetInit get called after a seamless travel? 🤔 I'm wagering no.

[clear island]

yea my server empty is at 10% cpu, 1 player joins, and it jumps to 50% 🙃

[winged badger]

For what actors?

[quasi tide]

Ones that would've been in the travel list

[winged badger]

Usually yes

[quasi tide]

Conceptually - they shouldn't

😱

[winged badger]

As pc and ps tend to get reinstsntiated

[quasi tide]

Yeah - I guess that's fair.

[winged badger]

Pc travrl list is usually empty

[thin stratus]

Unless PC doesn't

Then RIP

[winged badger]

And other actors are persisted only on server

[stiff oracle]

why i cant see my friends lobby when he hosts a game, and he cant see mine when i host, it works locally tho with the same network, but wont work when they are 2 different networks, how do i fix that?

[thin stratus]

PC not calling BeginPlay after SeamlessTravel still annoys me

[winged badger]

It is a weird choice

[thin stratus]

Are you using a Subsystem?

[stiff oracle]

yes

[thin stratus]

Which one

[stiff oracle]

the base one

[thin stratus]

The base one doesn't support Sessions outside of LAN

[stiff oracle]

ahaaaaaaaaaaaa

i am dumb

[thin stratus]

Sessions require a MasterServer aka SessionList

There is nothing you can add or request Sessions from with the NULL Subsystem

You'd need to use e.g. Steam

[quasi tide]

Yup - this tripped me up last night 😅

[thin stratus]

I'm sure i still have a bug in the Lobby kit cause of that

But it works cause I never travel from Gameplay to Gameplay

[stiff oracle]

alright thank u so much

[thin stratus]

I only travel Lobby -> Gameplay -> Lobby

Which recreates the PC

[winged badger]

PostNetInit is called as part of client spawning a replicated actor

[worn steppe]

I have a component that binds OnBeginOverlap/OnEndOverlap. It is attached to random BPs in the world. When a listenserver character enters the region, OnBeginOverlap is fired off with authority and everything works great. When a client character enters the region, OnBeginOverlap is fired off WITHOUT authority and since the component is not owned by the invoking client I can't even trigger a server RPC. Is there a proper way to fix this or do I need to only bind OnBeginOverlap/OnEndOverlap on the character itself and then have some kind of common interface that I call on the component itself or something?

[winged badger]

All collisions are local

[thin stratus]

The Collision should be triggered on everyone* no matter who walks over it

As in, OnBeginOverlap should trigger on Server no matter if Server or Client walk over it

[worn steppe]

That was my expectation but logging GetNetMode and GetOwnerRole seems to indicate otherwise

(unless I am misunderstanding something)

[thin stratus]

Idk what it prints for you, but with 1 Server and 1 Client, you should get two prints if a Client walks into the Collision

[quasi tide]

Yeah - which is why I would think that it wouldn't be called after a seamless travel.

[thin stratus]

One for the Server version of the Client's Characer and one for the Client's version

[worn steppe]

Is there a way to log to the dedicated server log?

that's in a console

[thin stratus]

UE_LOG

[worn steppe]

ty

[thin stratus]

UE_LOG(LogTemp, Warning, TEXT("[%s]"), *FString(__FUNCTION__));

Something like that

Or whatever else you want to write

[winged badger]

Not if the Actor persists on client, weirdest thing with seamless is that ServerNotifyLoadedWorld is called on departing controller

Makes for quite a mess if you have both lobby-game-lobby and game-game transitions

[sonic python]

Create Session Fails

A Question , Eos , How To Implementation Listen Server?

Will It Work On Standalone only when it is a Listen Server?

[winged badger]

You should not be starting sessions with standalone net mode

You can, but you shouldnt

[worn steppe]

so, characters are owned by the client, but, is it OK to keep extra state information on the 'server side instance' of the character?

[winged badger]

Elaborate

[worn steppe]

my character presses an keyboard key, this calls some function (bound using the enhanced input action system). my understanding is that this function is executed on the client. I need it to talk to a component that is attached to a BP that is owned by the server. to do that, the only thing I can do (to my knowledge), is run a server RPC on the character itself from the bound input action function. but, at some point at some earlier time, that component needed to register with my character that it was "subscribing" to my characters input events. I suppose I could invoke a client rpc and maintain the list on the client, but I figure I may as well just do it on the server instance of the character since the client doesn't actually need to know about this list, it just needs to exist somewhere so when the input action is fired off and I invoke the server rpc to notify the component I have a list of components to notify

this is a complete jumble to try to talk about

[dark edge]

be specific. Your character doesn't press a keyboard key, your player does.

Anyways, what gameplay are you trying to do here?

[worn steppe]

well, my my player presses the keyboard key, the function that is executed is bound on the character class. In terms of gameplay, I have lets say a water source that the player can drink from. when the player walks near the water, they should be able to press E or something to drink from it

I imagine this will be the model I use for a lot of things, like picking up items from the ground, interacting with doors, chests, etc

so I'm trying to get it as right as can be now

[quasi tide]

1. Client presses interaction
2. Do local checks as needed
3. ServerRPC the interaction

[winged badger]

But, you should really send a pointer to the actor youre interacting with via that RPC

And have an interaction interface

[worn steppe]

my goal was to have the component register an on interact delegate to be called

[winged badger]

If you have 2 interactables right next to each other, server and client might nit independentky evaluate the same actor as target

[dark edge]

In pawn:
E -> Choose what to interact with -> Run on server event -> Interact interface call or component event
OR
E -> Run on server event -> Choose what to interact with -> Interact interface call or component event

Depends on how you want to do it but that's the general gist of it

[winged badger]

1st, always

[rich furnace]

Using Advanced Sessions for Steam, if I wanted to create private and public lobby, would I be using a separate "Create Advanced Session" for the specified lobby types I want?

[quasi tide]

I always do local checks before doing a ServerRPC - can save on unnecessary RPC calls

[worn steppe]

ok, in that case, I will keep the list of subscribed components on the clients version of the character. thanks

well well well, everything is working now. thanks everyone

[serene terrace]

hey hey
I want to ask a question so I am having problems with my game for some reason
I’ve been developing a multiplayer game, everything was working properly up until I reopened the project recently, and I was generally able to both create and join a session on the same machine without issue.

Randomly this issue has occurred where everything works fine and loads properly for the player that is creating the session, and they are able to jump into the level with the new game mode without problem. When a second player joined that session before, it USED to work just fine and load the same game mode without problem, but now it is straight up deleting the game mode before it even loads the level. It is still JOINING the session successfully but it is ignoring the default game mode for that level, its not maintaining the game mode from the previous map, there’s no pawns or controllers from what i can see and even though it has the time of day sky its either spawning the character controller in a really weird place or not loading the rest of the level at all. This would make sense, i guess, since all of the defaults are tied to the game mode itself. Why is this happening???
I have already tried everything I can and I cant find a solution I can hop in discord share my screen and I hope someone can help me
I am Using Unreal Engine 5.0

[dark edge]

or 2nd with a sanity check so client doesn't say they wanna interact with 1 thing but interact with another on server

depends on how close together your interactables are

[serene terrace]

does anyone know what is the cause for the problem

I have been stuck on that for the past 3 days at this point

[winged badger]

Client doesnt have anything to do with gamemode

[serene terrace]

okay so when I join my game now it says the first player has a gamemode but the second one doesnt and it doesnt spawn

[winged badger]

First player should get all login events when 2nd one joins

Also, and i cant stress this enough, joining a session is not the same as connecting to unreal server

Those just usually happen around the same time

[serene terrace]

then is their a reason for the second player not getting the gamemode

?

because I have specified for this map you should get Gamemode_MP but for some reason only the second player isnt getting it

[quasi tide]

Clients do not get the GM. It does not exist on clients.

Only servers.

[serene terrace]

got it

then their must be a reason for the second player to not spawn and I cant seem to figure it out

[dark edge]

Show your spawning logic in gamemode, if you have any

otherwise show your default pawn setting in gamemode

[stiff oracle]

i still cant find my friends sessions even after using online subsystem steam

any help please

[serene terrace]

I can refer you do a useful video

one sec

[stiff oracle]

oh please

[serene terrace]

https://www.youtube.com/watch?v=VOCnu940CGw&t=223s

this video helped quite a lot when I did it

[stiff oracle]

btw

[serene terrace]

yes

?

[stiff oracle]

when i tried to use the latest steamworks sdk

i was doing it by the documentation, it gave me steam sdk not found error

something like that

i then changed the folder's name back to the original version, and the steamwork.build.cs back to the original version but i didnt change the sdk folder back to its original one

[serene terrace]

I am unsure of that I didnt dabble much in steams online subsystem

I would recommend watching the video fully then trying to see if it works again

[stiff oracle]

alright thanks anyways 😃

[serene terrace]

wlc wlc glad I can help

[twilit radish]

Quality CMC extension code, could definitely be shipped 😆

[prisma snow]

brrrrrr

[worn steppe]

can't wait to play PaintShaker Simulator 2023

[twin juniper]

Okay so I asked in c++ but didn't really figure it out. I have a c++ character that is not replicating it's movement to the clients. If I run the game in standalone or listen server then my character moves when I issue a move command to it's ai controller. But it doesn't replicate in client mode

[pastel escarp]

when is replication variables are considered too much ?

Is it like 10 replicated property per actor ? 50 ? 100 ?

[prisma snow]

I don't think there is a number, it depends on the number of actors, how often the variables change...

efficiently done, Unreal can handle hundreds and thousands of data per second, but that requires understanding the system and your game and context very well

[pastel escarp]

Many thanks ! I will continue researching this topic as well

[twin juniper]

For anyone wondering, I just solved this. I had to set the capsule component to replicate. The weird thing is that my old blueprint based characters don't have this set but still work?

[sonic python]

Like For Testing?

The Create Session Fails on Mobile and Standalone

Why is that?

Even if Lan Is True , It fails

[oak oracle]

Hey devs , i was watching some video on Crouch on youtube , and what he did is this (Screenshots) and evrything worked just fine both on Server and Client , i don’t get why its crouching fine on Server if the actual crouching code is inside of On_Rep functions . Isin’t repnotify functions should get called only on client?

[graceful flame]

Use the network profiler tool to find out which actors have lots of waste and should be optimized. You can also use unreal insights for a closer look at the impact of your network related updates on a frame by frame basis.

[pastel escarp]

Will use them, Thanks !

[sonic python]

Maybe this is related to Eos Online Subsystem

Online Subsystem Eos is enabled, other Subsystem like steam is not.

Except Google Play, for in app purchase

So Like Why Is Create Session Failing?

Just Want to Know Why.

[pale obsidian]

C++ OnReps get called only on clients, while Blueprint OnReps get called on server and clients. If I recall correctly.

[prisma snow]

I know this is not strictly UE, but I found a very interesting article about networking:

https://www.gamedeveloper.com/programming/dead-reckoning-latency-hiding-for-networked-games

[twilit radish]

I skimmed through it, but I don’t think this is useful for most games. They are making the assumption that you can predict what something does and that it does this in a mostly deterministic way. Unreal is not so great on deterministic stuff if you ask me. Along with that games are extremely unpredictable, players are completely unpredictable and AI behavior can change any second based on.. You guessed it. Those unpredictable players 😛
Although I think there would be scenarios where you can apply it to, but I doubt it will matter a whole lot.

[quasi tide]

Why does the fast array require the variable to be named Items? What happens if you have more than one in a class?

[fossil spoke]

It doesnt, it may have in the past, it doesnt anymore.

[quasi tide]

I've been deceived

Bamboozled even

[dim trail]

i dont understand why initgameplaystats is being called before setupgasdelegates

        if (HasAuthority())
        {
            //setup attribute change delegates
            SetupGASDelegates();

            //initialize gas on the server
            GetAbilitySystemComponent()->InitAbilityActorInfo(this, this);

            InitGameplayStats();
                }

[fossil spoke]

You might need to give us more context....

[dim trail]

when i debug, the initgameplaystats gets called BEFORE steupgasdelegates. these are being called in the possesedby method on the pawn

I dont understand why thats the case?

the whole method:

//Needs to init gas on possessed by
void APlayerCharacterBase::PossessedBy(AController* NewController)
{
    Super::PossessedBy(NewController);

    if (GetAbilitySystemComponent())
    {
        if (HasAuthority())
        {
            //setup attribute change delegates
            SetupGASDelegates();

            //initialize gas on the server
            GetAbilitySystemComponent()->InitAbilityActorInfo(this, this);

            InitGameplayStats();
            InitInitialGameplayEffects();
            InitGameplayAbilities();

            UCombatComponent* ThisCombatComponent = FindComponentByClass<UCombatComponent>();
            if (ThisCombatComponent)
            {
                //ThisCombatComponent->InitAvatarActor(this);
                ThisCombatComponent->OnDeathDelegate.AddDynamic(this, &APlayerCharacterBase::OnDeath);
                ThisCombatComponent->OnKillDelegate.AddDynamic(this, &APlayerCharacterBase::OnKill);
                //ThisCombatComponent->TargetActorReplicationDelegate.AddUObject(this, &APlayerCharacterBase::OnTargetChanged);
            }
            OnInitGAS.Broadcast();
        }
        //GetAbilitySystemComponent()->GetNumericAttributeBase(URagnaAttributeSet::GetJOBEXPAttribute());
    }
}

[fossil spoke]

How are you determining that its being called before? Seems like you are misinterpreting something. It cannot be called before since the function is literally after.

[dim trail]

the call stack

let me check something

[autumn prairie]

Are there any other networking settings like this? That you can apply to your either character or cmc. https://docs.unrealengine.com/5.1/en-US/API/Runtime/Engine/Engine/ENetworkSmoothingMode/

ahh found some 😄

seems good for now. i need to read more up on this tho. NetworkSmoothingMode = ENetworkSmoothingMode::Linear; NetworkMaxSmoothUpdateDistance = 50.f; NetworkLargeClientCorrectionDistance = 500.f; NetworkMinTimeBetweenClientAckGoodMoves = 0.1f; NetworkMinTimeBetweenClientAdjustments = 0.05f; NetworkMinTimeBetweenClientAdjustmentsLargeCorrection = 5.f; NetworkNoSmoothUpdateDistance = 25.f; NetworkSimulatedSmoothLocationTime = 0.1f; NetworkSimulatedSmoothRotationTime = 0.1f;

[copper grove]

probably a dumb not 1 size fits all solution but i dont really see any good places for discussion about these 3 values:
MaxClientRate=15000
MaxInternetClientRate=15000
NetServerMaxTickRate=60

like what is an acceptable rate for a multiplayer shooter... granted ok, you increase tickrate, should make the game more responsive in theory right, but then you can probably host less games (without massive optimizations)

so is its fine jsut setting it to 30?

or this like, a thing of the past and everything should be at least 60

[fossil spoke]

Entirely depends on your game, how well its optimized and your targets.

The higher the tick rate the more performance heavy it will become, the less instances you could theoretically handle.

[copper grove]

right, thats what i wonder in terms of costs vs gameplay feel

[fossil spoke]

Its very very dependent on your game. Thats why there isnt a lot of resources that talk about specifics.

Unfortunately.

The ClientRate is just the net speed.

In todays conditions its fine to push that up pretty significantly from the default.

[subtle patrol]

Not sure if this is multiplayer related question but I want to ask how many games that have online servers, do announcements in game from somewhere else

[autumn prairie]

these are default engine settings right?

just wondering.

[fossil spoke]

Its not uncommon for an ingame UI element to read an external API that developers can make "announcements" to display ingame.

[subtle patrol]

Hm that’s the way

Thanks

So let’s say I can trigger an event from a http request?

Something like this right?

[fossil spoke]

Likely what would be appropriate is a HTTP request to an API like GetMessageOfTheDay, which would return the latest entry in some Database somewhere that contains the "announcement".

[subtle patrol]

That’s seems perfect

[rose pollen]

I have a custom child class of primary data asset that is used as a payload for a gameplay event. the event happens server side and I to do some stuff and then send to payload to the clients via an RPC. however, not to surprisingly, the data asset doesn't go through the rpc and the client just has its event called with none as the input. If I take the same code but pass a string through every works so I guess the issue is in serializing the data asset. Is that just not possible or is there some interface that the data asset could implement that would allow it? In general is there a proper way to pass a primary data asset from the server to the client or should that not be done?

[snow thorn]

does anyone know how to replicate that code properly

im making a chat box

the print string replicate fine but the widget doesn't have the same text for both clients

can anyone help with this

[tight crow]

set the text variable to replicated?

"New Text"

[snow thorn]

na that doesnt do anything if its on or off

its the text that isnt being displayed

[tight crow]

you can also try running it through a server > Multicast? Thats the only two things i personally would try

I made one in an old project, and i remember going back and forth to get it to show on both. Ill try and find the BP and screen shot

[snow thorn]

oh thanks

[tight crow]

im opening it now, havent opened it in a year so its taking forever

[snow thorn]

all good man tysm for even helping. i thought it would be ez but ive gotten stuck on this last part

[tight crow]

multiplayer is crazy. Its the simple stuff that seems the hardest to do lol

[snow thorn]

ya thats why i was trying to learn through this

[tight crow]

im gonna DM you because its a few pics and I dont wanna blow up this chat lol

[snow thorn]

sounds good to me do i have dms open?

[dark edge]

Widgets don't replicate

Chat should live in GameState or something

UI is a VIEW of the data, it is not the data itself.

[snow thorn]

Ohhhh that explains a lot

[dark edge]

Your chat should go something like:

Text entry -> run in server event in playercontroller -> multicast in GameState or ChatManager

[snow thorn]

well got it to work guys

[native tapir]

I'm trying to call server rpc in client using UActorComponent that attached to PlayerController but seems like Server RPC doesn't working in UActorComponent even the owner is PlayerController Is there anything I misunderstood for server and client relationship?

[kindred widget]

Is it a default actor component, or an attached one?

[native tapir]

It's attached to playercontroller

[kindred widget]

But created at runtime or as a default component?

[native tapir]

It's default component.

[kindred widget]

That's odd then. You should be able to RPC even without the component as replicated.

[native tapir]

Well, It's not working I think Server RPC function always need to place in playercontroller..

What i was trying to do is separate some ability like interact ability and attack ability to using actor component and communicate with server but those are not working.

Because I really don't want to put all functionality about Server RPC in playercontroller.

I want to organize another way but I assume there's no way to do that..

Am I right?

[upbeat basin]

Well splitting the logic with components, even for multiplayer stuff, should be a valid way to organize things

Are you sure you're using your own controller and not trying to get the owner/controller of the object/actor you are interacting with?

[native tapir]

I'm attached component to playercontroller and I'm calling ServerRPC inside of component. Is this wrong?

The Code :

void UInteractibleAbility::Interact()
{
    if(IsValid(AvailiableInteractibleActor))
    {
        SR_Interact_Implementation(AvailiableInteractibleActor);
    }
}




void UInteractibleAbility::SR_Interact_Implementation(AInteractibleActor* InteractibleActor)
{
    if(IsValid(InteractibleActor))
    {
        InteractibleActor->Interact();
    }
}

It's simple just linetrace to interactibleactor and if player just press e then Interact function just calling SR_Interact function which is UFUNCTION(Server, Reliable)

And InteractibleActor :
Code :

void AInteractibleActor::Interact()
{
    SR_Interact();
}

void AInteractibleActor::SR_Interact_Implementation()
{
    IsInteract = !IsInteract;
    if (IsInteract)
    {
        InteractDelegate.Broadcast();
    }
}

void AInteractibleActor::OnRep_Interact_Implementation()
{
    if (IsInteract)
    {
        InteractDelegate.Broadcast();
    }
}

Interactible Actor is calling SR_Interact BUT! It's not triggering with warning : LogNet: Warning: UNetDriver::ProcessRemoteFunction: No owning connection for actor BP_InteractibleActor_3. Function SR_Interact will not be processed.

Is there any mistake...?

It's working in playercontroller but trying to seperate functionality to using actorcomponent is not working....
I think there's something I misunderstanding but I can't find out

[kindred widget]

You're calling a server function on the InteractableActor.

[native tapir]

I'm calling it because I assume interactibleAbility called it in server side inside of SR_Interact(UInteractibleAbility)
Is this not correct..?

[kindred widget]

If the Actor is never meant to be owned, ditch any networking related to Server/Client. It should only have OnReps, and Multicasts. It'll be easier to debug. Then put a breakpoint in the component's SR_Interact. See if that breaks in gameplay. If it does not, put a break in Interact and see what your component's state is. It's owner should be PlayerController, check the netmodes, etc.

[upbeat basin]

Hmm I want to say that your component should also be replicating in order to call RPC from it but Authaer said otherwise, so I'm not sure

Putting breakpoints should help us more on that, maybe your component is required to be replicated for the UInteractibleAbility::SR_Interact_Implementation to be called on the server. Maybe your argument you give to (aimed interactable actor) it isn't being replicating hence when the function executes in server it doesn't have a valid InteractibleActor to call the AInteractibleActor::Interact on it

[kindred widget]

Name stable ActorComponents don't need to be replicated to RPC, just to replicate. The RPC is sent through the actor channel and the connection can resolve the component on the other side by name even without replication if it's name stable. By default any default components in the class are name stable. Anything added at runtime needs special work to name it name stable

[native tapir]

I grab some information about this https://docs.unrealengine.com/4.27/en-US/InteractiveExperiences/Networking/Actors/RPCs/
And there's say
Requirements and Caveats
There are a few requirements that need to be met for RPCs to be completely functional:

They must be called from Actors.

The Acto...

Is that means RPC must be called from actor?

[upbeat basin]

What does being name stable mean?

[native tapir]

not working in actorcomponent?

[fierce grove]

I have a server owned actor that needs to explose ... to broadcast this explosion with particles.... is the only way Multicast?

[native tapir]

I've already replecated components

[kindred widget]

Meaning it has the same name for the same component on the server and the client.

[winged badger]

Object, actors can have those too

[kindred widget]

Yeah. 😄

But the TLDR is that you don't need a replicated component. It just has to be name stable on a replicated actor to RPC, as it goes through the actor's channel to do the networking.

[upbeat basin]

Is this when I use something that is replicates as the argument of an RPC, how it being resolved on the other device?

[winged badger]

And its name stable by default only if its a default subobject

[upbeat basin]

Using this name?

I'm considering it's an FName?

[winged badger]

Not quite

All actors from level have same nsme on all machines

All rheir defsult vomponents have a same name relstive to their actor owner

So an object csn be resolved by name over the network

But the name only gets sent once - after which its replaced by NetGUID

Ssme thing applies for asset pointers, their names are always the same in the package, same as level actors

None of those need to be replicated for you to be sble to replicate pointers to them

Replicated actors are assigned a netguid as they spawn , and are never resolved by name

Their default components have a stable name relative to owner

And as owner can be resolved, so then can the components

[upbeat basin]

So this should apply to default components of both default actors in the level as well as the spawned ones since their owner can either be resolved by their names or NetGUID?

[winged badger]

Yes

[upbeat basin]

Got it, thank you very much

[upbeat basin]

So coming back to this, just to be sure, the replication of a default component only matter if there are replicated variables in it?

[winged badger]

Kinda, you have to keep in mind that there are engine base component classes as well, that sometimes replicate stuff too

like attachement replication in USceneComponent

so its not just your replicated variables

[upbeat basin]

Got it, thanks again, to both of you

[sonic python]

Ok Stuck

Guys Does Anyone Know ,Why Create Session Fails on Standalone.
Online Subsystem Eos is Enabled.

And If Possible How to fix that?

[twilit radish]

I would suggest asking in #epic-online-services , also provide some logs or something similar in there. No one can magically guess what the issue is 🙂

[sonic python]

There are No Errors in the Log

Like Simply The Create Session Fails

Is it because of Eos?

[twilit radish]

EOS doesn't have to be the issue, it could be, but in general it works just fine for a lot of people. But like I said try asking in #epic-online-services as people there know a lot more about the issues that can happen with EOS then we do in here. There's also Epic staff in there usually.

[gilded hedge]

Remember also to pump those logs to Verbose or even VeryVerbose

[sonic python]

Verbose?

What's that?

[sonic python]

Ok I'll try there , But I'm using the paid version, So there should be no error with Eos right?

[gilded hedge]

It's the amount of logs you can get from a specific module.

https://unrealcommunity.wiki/logging-lgpidy6i

Check the different log levels here

But long story short, if you need details on why something is failing it's always a good start to figure out where that system is logging and increase the related verbosity in your settings. I think for Eos you'd start with LogOnlineSession

[sonic python]

Ok In Session Frontend

I get this warning

LogScript: Script Msg : Create Session - Cannot Map Local Player to unique net Id

[gilded hedge]

That's where you lose me, I'm not super familiar with the online subsystem. An initial guess would be that standalone doesn't support features like assigning local players a network id. Or maybe you should just trigger a login before attempting to start the session. Post this in the Eos channel and see if someone can help further!

[sonic python]

Oh Ok

Thanks Man

[prisma snow]

Is it possible to connect two packaged games using the command line? I want to test something in a packaged build (to rule out some possible editor interference) and it would be quicker if I don't have to do a connection menu widget

And One More Thing Like Is It Compulsory to Make The Player Log in

[sonic python]

Ok now the Create Session Fails Even In Play in editor

[kindred widget]

What do you mean by this?

[sonic python]

Like Should The User Should Be Logged In?

Like Should There Be User?

And One More Thing

Should I Authorise Epic Game Account

[oak oracle]

hey devs , can someone please explain why my multicast RPC only executing on Server ?

[gilded hedge]

you must login to use EOS. And you need to authorise your own project, yes

[sonic python]

When I Click Authorise Epic Games Account

It says Oops! It looks like the Authorisation didn't start up correctly as there is no log file present .Please Contact Support

[gilded hedge]

seems like something is misconfigured on the eos side of things

[verbal tendon]

Step 1: Make sure you setup the tokens with full permission so that it is not a permission error

Step2: Make sure you entered the correct values in your INI files

Step3: Make sure the workflow is correct
