#

and very messy

#

and i never got it working

#

funnily enough, exact same use case... pooling projectiles

#

this was in like 4.12 tho

#

and the underlying code there has changed quite a bit

#

it's much more tolerant to errors now

#

but, i still don't think it will work very well

#

however, if you can figure it out, definitely let me know

#

you might be able to spin up a NetChannel to send "new proejctile GUID" information and do the remapping when packets come in

#

I'm interested in one day doing a dynamic reallocation of simulation authority type deal

#

where you have a number of "peers" (could be servers, could be other clients) and have them change hands on who is simulating what

#

seamlessly and in real time

#

Ah yeah I decided against it in the end, was just an idea that popped into my head this morning that might have warranted more investigation... but then there's other things I didn't think about, like existing references etc.

gleaming vector Feb 8, 2020, 8:15 PM

#

yeah

#

it's very messy

#

the GUID isn't intended to change during the lifetime of an actor

#

i ran into all kinds of issues once I actually figured out how to make the change

#

mainly crashing

chrome bay Feb 8, 2020, 8:15 PM

#

It's almost entirely just for making sure particle systems stay "relatively" sync'd so there isn't a horrible visual artefact, but I think I that's easier and I can do it case-by-case

#

Yeah that makes sense

#

Glad I didn't go in then 😄

gleaming vector Feb 8, 2020, 8:16 PM

#

but, like i said, this was back a few years ago now

#

and that code went under a rather significant revision by 4.19

chrome bay Feb 8, 2020, 8:16 PM

#

nps

#

I'm certain it wouldn't have been straightforward anyway

#

And even if I get it working any obscure errors will be so difficult to debug

gleaming vector Feb 8, 2020, 8:18 PM

#

yeah haha

nocturne osprey Feb 8, 2020, 9:08 PM

#

hello i have an issue with multiplayer replication, if someone could give me hand please!

#

so basically i have a client which doesn't move on the server side

gentle lion Feb 8, 2020, 9:11 PM

#

Your going to have to be a bit more descriptive than that. There could be hundreds of possibilities as to why this happens. Not to mention we don't know your setup

#

Are you using the character movement component?

nocturne osprey Feb 8, 2020, 9:12 PM

#

well i can give you some screenshots

#

no it's the floating movement component

#

im putting a few screenshots then

#

📎 Player_controller_input.PNG

#

📎 Player_controller_server_function.PNG

#

this is from my player controller bp

#

when i put my custom events to run on server, the client doesn't move at all, and when i put them on multicast or run on owning client, the client move but the server cant see him moving

gentle lion Feb 8, 2020, 9:15 PM

#

Is replicatesmovement set to true?

nocturne osprey Feb 8, 2020, 9:16 PM

#

it is since i can see the server moving on the client side

#

well when i say server it's the host

pallid mesa Feb 8, 2020, 11:23 PM

Guys there way to change server tick rate and client tick rate?

severe cedar Feb 9, 2020, 3:29 AM

#

My project has been dedicated server with connected clients so far, so it's been easy to differentiate between the server vs client instances of replicated Actors (like Characters) via net mode < NM_Client checks etc. This is useful for if we want to do certain logic only on server or only on client.

We want to also try supporting listen server, but I'm less familiar with this and was wondering if people could help answer a few questions?

1/ In listen server, is the hosting client considered a server or a client? My understanding is that if we were to use a net mode check, it would be server?
2/ If it would count as a server/if there is only one instance in listen server for the host, what is the recommended way to branch logic b/w "server" and client?

winged badger Feb 9, 2020, 5:54 AM

#

the server part works the same @severe cedar

#

the difference with listen server is that it also has a local player

#

nothing more

#

you might want to check specifically for dedicated server before you start running the UI and such, unless all of it is ran directly from the PC/Owned Actors

#

and you have to run the local client logic server side

#

IsLocalController/IsLocallyControlled starts to creep in into your net mode checks

#

so you can differentiate between the listen server host and the other players

stark hull Feb 9, 2020, 6:23 AM

I've run into an interesting widget problem, as when I restart the players after they die (detach pawn from controller and destroy it) with a brand new pawn, It seems that the on screen widgets stop reacting to the health updates (as the health is handled by a component attached to the destroyed pawn). All the rest of the data is fine as it's connected to either Player State or game state that don't get destroyed. My question is then, what would be the correct approach with rebinding component data to an onscreen widget?

#

I suppose that the problem is stemming from a dead reference that my widget has when the health component gets destroyed, but then why wouldn't it throw a nullptr exception...

#

Would it be a generally better idea to let the health component talk to the PlayerState, and then the widget would grab the data from the player state?

thin stratus Feb 9, 2020, 7:43 AM

#

@stark hull Correct

#

If you destroy the pawn, it will destroy the component. If you saved these in the widget, then you have to update them after you got a new pawn

#

What the component talks to is not really important. You should just use one of the events of the controller (here most likely OnRep_Pawn) to tell the owning client to update their pawn refs in the widget

weary zephyr Feb 9, 2020, 12:16 PM

#

Does anyone here have any experience using Smooth Sync for MP replication of player characters?

#

I'm using it, and it seems to be working fine, but I'm having an issue where it seems as though replicated variables have a mandatory .5-ish second delay on their replication when using Smooth Sync? It might be something else I'm seeing, but that's what it seems like. Im running both clients and the server on my local system though, so the delay really shouldn't be present

ember needle Feb 9, 2020, 4:08 PM

#

All, I am setting the variable RemoteViewYaw in my custom character code:

#

void AOSACharacter::PreReplication(IRepChangedPropertyTracker & ChangedPropertyTracker)
{
    Super::PreReplication(ChangedPropertyTracker);

    if (Role == ROLE_Authority && GetController())
    {
        SetRemoteViewYaw(GetController()->GetControlRotation().Yaw);
    }
}
void AOSACharacter::SetRemoteViewYaw(float NewRemoteViewYaw)
{
    // Compress yaw to 1 byte
    NewRemoteViewYaw = FRotator::ClampAxis(NewRemoteViewYaw);
    RemoteViewYaw = (uint8)(NewRemoteViewYaw * 255.f / 360.f);
}

and

UPROPERTY(replicated)
uint8 RemoteViewYaw;

void SetRemoteViewYaw(float NewRemoteViewYaw);

#

but when I set on character SetReplicateMovement to false the variable RemoteViewYaw doesn't get updated anymore.

#

Still, the character is replicated (only movement replication gets set to false), so why does the variable stop getting updated?

meager spade Feb 9, 2020, 4:16 PM

#

does it actually get called

ember needle Feb 9, 2020, 4:16 PM

#

you mean PreReplication?

meager spade Feb 9, 2020, 4:16 PM

#

yeah

#

thing is

ember needle Feb 9, 2020, 4:17 PM

#

let me triple check

meager spade Feb 9, 2020, 4:17 PM

#

if you have 0 replicated properties

#

it wont ever call

#

(ie PreReplication is only called when a property changes)

#

hence why you see the behaviour issue with replicate movement

#

as nothing is changing on the actor (regarding properties that need replicating) then pre-replication will never be called

#

with replicate movement set to true, its replicating all the time the player moves

#

meaning pre-replication is called.

ember needle Feb 9, 2020, 4:19 PM

#

so if I were to add a stupid replicated bool variable that changes all the time on server (as an example) then it would get called?

meager spade Feb 9, 2020, 4:19 PM

#

yes

ember needle Feb 9, 2020, 4:19 PM

#

hum.

#

what is my best to approach this then?

#

basically I need to replicate pitch & yaw but not position

#

this works nicely and is also compressed when movement is replicated.

tall pine Feb 9, 2020, 8:28 PM

#

Hi everyone,

If I have function in GameState that only run when i have authority, should I just move it to GameMode instead?

pulsar maple Feb 9, 2020, 9:06 PM

#

Does anybody know what changed with CharacterMovementComponent replication in 4.24? I was getting a ton of small network corrections with basic locomotion, but switching to 4.23 drastically decreases them.

final rover Feb 10, 2020, 2:29 AM

#

hey, so I'm having an issue where in multiplayer my player's inputs are all delayed by the ping to the server. Afaik what I want to be doing is to process the movement locally, and then also process it server-side and then do some interpolation magic to smooth stuff out. I guess what I'm trying to find out is, how do I let the player do local movement stuff while connected to the server?

hollow iris Feb 10, 2020, 3:09 AM

#

EILI5: What would be the proper process here (C++)? I have a character that has a pointer to a inventory component that is on PlayerState. I need to set the inventory's contents OnRepPlayerState with default items. What does that RPC chain look like?

#

Inventory component is set to replicate. The inventory array is on RepNotify.

#

@meager spade you are usually the guy with the answers. 😛

thin stratus Feb 10, 2020, 5:56 AM

#

@final rover By default only the Character class with the CharacterMovementComponent can do that.

final rover Feb 10, 2020, 5:57 AM

#

yeah I'm using that

thin stratus Feb 10, 2020, 6:04 AM

#

Then it should work out of the box using AddMovementInput nodes

final rover Feb 10, 2020, 6:06 AM

#

yeah probably because I'm using root motion

#

doesn't seem to work for jumping though, which doesn't use root motion in my project. I'm just using the built in Jump function

thin stratus Feb 10, 2020, 6:31 AM

#

Non-root motion should also work just fine.

#

The whole CMC is created for that.

echo geode Feb 10, 2020, 11:32 AM

Thanks god CMC replicates all of networking movement for Characters

@pulsar maple Having similar issues. Really big problem, but haven't see much reaction to it

sacred spire Feb 10, 2020, 2:53 PM

#

Report to Epic and tell them it is bug maybe?

chrome bay Feb 10, 2020, 3:02 PM

#

Most obvious first thing to do would be try it in a blank project. That's the first thing Epic will ask you to do anyway

#

If it's not occurring there, with the default movement system, then you can at least narrow it down to the project itself.

#

Personally I'm not seeing any issues, but I've not done much with characters in 4.24 so far tbh

rose egret Feb 10, 2020, 3:46 PM

#

is there any config to delay sending of packets for a client? I want to make at least 3 seconds delay for spectators

chrome bay Feb 10, 2020, 3:51 PM

#

There isn't

#

Just use a timer, send the RPC when it expires

rose egret Feb 10, 2020, 4:16 PM

#

I want the hole game to be delayed (replication, RPCs, ...) for spectators . could not be much hard since its just a delay. like a proxy

split gust Feb 10, 2020, 4:18 PM

#

is your game sending ALL the info to the spectators no matter what? aka no occlusion of stuff they cannot see?

#

because if not that might make the delay hard to do

I am trying to create a dedicated server with a login. I am not sure the best way to do it, therefore does anyone have any suggestions?

tall pine Feb 10, 2020, 7:27 PM

Hi everyone,

If I have function in GameState that only run when i have authority, should I just move it to GameMode instead?

I'm fuzzy on what should go into GameMode and what should go into GameState

thin stratus Feb 10, 2020, 7:27 PM

@scarlet cypress #work-in-progress

I usually keep server only code in the GM

tall pine Feb 10, 2020, 7:28 PM

Another question: I want when player connects to game, assign specific pawn to him, how to do this? I tried spawning all characters in advance (when no players connected) in gamemode BP, but the pawn looks kind of 2d, I understand that it is kind of DedServer optimization.

ivory flame Feb 10, 2020, 8:37 PM

@thin stratus My Dedicated Server fetches level that it should load on startup, then it opens it, I guess the reason why port is incremented is that I use Open Level to open new level in Dedicated Server

@thin stratus I am looking for suggestions. (My coding background is really not in gaming. I could code this the way I have for in the past for non gaming applications.

@half gust I'm using Nodejs + socketio for authorization, nodejs server acts as a master server which manages all Dedicated Servers, you can use the same, or(if you don't need sockets), then just use VaRest http client for connection to nodejs express server

#

Just google nodejs express server tutorials, there are tons of them, then use VaRest plugin to connect your client Unreal app to that server

Hey guys on Online session should i use Get Player Controller [0] or there are another method ?

little bloom Feb 10, 2020, 9:22 PM

#

I have an issue with the host or first player that joins a dedicated server losing control of their pawn when a second client joins

odd iron Feb 10, 2020, 9:23 PM

#

@little bloom i think we have same issue Because you are using get Player Controller [0] right ?

little bloom Feb 10, 2020, 9:23 PM

#

No, Get Controlled Pawn is returning null

odd iron Feb 10, 2020, 9:24 PM

#

hmm

little bloom Feb 10, 2020, 9:28 PM

#

Made a work around actually after I just typed that out. Sets a variable to the character and repossesses it if controlled pawn is null

thin stratus Feb 10, 2020, 9:29 PM

#

@odd iron No, unless you are 100% aware of what you are dealing with

#

It's better to use GetController etc relative to the pawn you are in

#

Or GetOwner if you are in the PlayerState

odd iron Feb 10, 2020, 9:30 PM

idk i faced problem with HUD Replication on my other project its just showing the correct hud on player 0

integer

thin stratus Feb 10, 2020, 9:31 PM

Are we talking HUD or Widget?

odd iron Feb 10, 2020, 9:31 PM

#

HUD

thin stratus Feb 10, 2020, 9:31 PM

#

And are you replicating that inside the "HUD" or outside?

ivory flame Feb 10, 2020, 9:32 PM

#

No, Get Controlled Pawn is returning null
@little bloom May be because your pawn haven't been possessed yet? Where are you calling it?

odd iron Feb 10, 2020, 9:32 PM

#

i was replicating the varibles on character bp

#

idk if im doing that right

thin stratus Feb 10, 2020, 9:33 PM

#

Hm no that sounds right. Either way GetPlayerController0 is not a good deal in multiplayer

little bloom Feb 10, 2020, 9:33 PM

#

It's the default spawned characters set in the game mode @ivory flame
It's possessed, but loses possession when a client joins, and it only affects the first client that joined

thin stratus Feb 10, 2020, 9:33 PM

#

It referes to the pc of the player you call it kn

odd iron Feb 10, 2020, 9:33 PM

#

Yes it was working normal on Host but Clients was value 0

#

all the time

thin stratus Feb 10, 2020, 9:33 PM

#

If you e.g. multicast in a players Character and then call GetPlayerController0, you'll get a lot of different controllers

#

Just as a random example

odd iron Feb 10, 2020, 9:34 PM

#

ok

#

i will check what can i do 😄

#

and for Advanced Session can i use GetPlayerController 0 Right ?

#

its will not effect

#

i mean if it was dedicated

thin stratus Feb 10, 2020, 9:35 PM

#

That us usually called locally from the UI or so, so that's technically fine

#

Also you should use widgets and not the HUD class

Just as a note

Hey quick question. I'm implementing a multiplayer game that uses seamless travel to travel from a multiplayer lobby to the game map. I have overridden Handle New Starting player in my game mode to find the appropriate player start and spawn/posses a character at the player start location after the seamless travel completes. However, in my packaged version of the game, sometimes I can't find the appropriate Player Start when I search for it in the level ( currently using a very basic GetAllActorsOfClass and do a name comparison). Is it possible that the level hasn't loaded the Player Start actors by the time Handle Starting New Player is fired? thanks for any help!

tall pine Feb 11, 2020, 12:09 AM

#

Where should I put a duration of the match that the game is taking place in? Is that in GameMode?
The reason I asked because if I put it in GameMode, then during the match, I'll have to continuously ping the GameMode (Server) to ask for what the current time is.
OR is there a better way of doing this?

#

Or should I tick the game time in GameMode, then write out the value into GameState, and then everyone can access it in GameState?

Hey guys I have a question for testing open ports. Currently when trying to host a listen via console command "open [levelname]?listen it seems outside player cannot connect to my computer when hosting. Port is open (7777), Ip is correct, the command is properly entered. However, when my brother hosts on the port I can connect to him via the same commands. For some reason on my computer only players cannot connect. Any ideas as to why this might be happening? I am also wired to the network, before i was wirelessly connected but changed that because i thought that was the issue originally. Thanks in advance!

little bloom Feb 11, 2020, 1:31 AM

#

You likely have a firewall blocking the connections on your own machine, I don't have time to look up specific guides, but that should give you enough to google @mint roost

timid moss Feb 11, 2020, 1:34 AM

#

Also i heard that your ISP could be preventing yyou from port forwarding for outside connections. I'm currently experienccing that and need to call them to try to see if theyl let me.

#

if you do your firewall setup right, and it still doesn't work, maybe check if your ISP doesn't allow it

mint roost Feb 11, 2020, 1:37 AM

#

@little bloom i even tried after disabling my firewall and was still not able to. So it could be ISP @timid moss

#

I know the port isn't the issue, that's for sure. Because im able to connect when my brother hosts on his machine. But when I host on my machine it doesnt allow him to connect

timid moss Feb 11, 2020, 1:40 AM

#

i wasted too much time trying to figure out this problem. But I found out that if you goto https://www.yougetsignal.com/tools/open-ports/ and test the common ports that most computers have open but the website says they are closed, that most likely means its a problem with your ISP. For me that website says like all my ports are closed, even when firewall is off, so pretty sure its my ISP. That could maybe be a way for you to find out as well

Open Port Check Tool - Test Port Forwarding on Your Router

The port forwarding tester is a utility used to identify your external IP address and detect open ports on your connection. This tool is useful for finding out if your port forwarding is setup correctly or if your server applications are being blocked by a firewall.

mint roost Feb 11, 2020, 1:41 AM

#

I'll have to give this a shot. Thanks man

#

I just dont get why his machine would be able to host and not mine. Both have the open ports. Proper rules setup.

timid moss Feb 11, 2020, 1:48 AM

you both on the same lan?

because for me i can do lan connections all i want. but when it comes to someone external from my lan joining. it fails

We're both on same lan. And connect lan. Bit if we try to connect to the public open port it only works if he hosts

mint roost Feb 11, 2020, 1:50 AM

#

So if he does the ?listen command and i do open ipaddress (not lan address) i can commect to him

#

But if i do ?listen and he does open ipaddress nothing happens. Super strange

timid moss Feb 11, 2020, 1:51 AM

#

are you doing dedicated server?

#

because if you are maybe u can see a message in the terminal of what went wrong

mint roost Feb 11, 2020, 1:52 AM

#

No we are not. Just listenserver hosting

timid moss Feb 11, 2020, 1:53 AM

#

also I would try swapping wifi recievers. make sure theres nothing wrong with the wifi reciever

mint roost Feb 11, 2020, 1:55 AM

#

I actually switched so im hardwired in, cause previously i thought wifi may have been causing the issue

timid moss Feb 11, 2020, 1:57 AM

#

if you happen to have a hotspot feature on your phone maybe try connecting to that and then try to open server connection

mint roost Feb 11, 2020, 2:10 AM

#

I could. I just shouldnt have to go through all that. Shouldnt be that difficult to do listen server.

timid moss Feb 11, 2020, 2:12 AM

#

idk. its just an option. for me i use my hottspot often so i was able to do a quick test just to narrow down the problem a little. did u guys try pinging eachothers' computers?

#

maybe try pinging the IP your trying to connect to and see if it works

#

like go to the terminal and type this cmdping [IP]

limber gyro Feb 11, 2020, 2:18 AM

#

is there any event that gets called when the player array changes?

#

@mint roost whats ur issue?

#

ok i was reading the chat

#

have you checked if you have anything else running on the 7777 port?

mint roost Feb 11, 2020, 2:23 AM

#

@timid moss enter that into the command prompt terminal or unreal terminal?
@limber gyro I'll have to check. And my main issue is me hosting on open port 7777 on my machine so outside players can connect. Not peer to peer. So when my brother hosts on his machine on the open port i can connect to him when he hosts. But not when i host.

limber gyro Feb 11, 2020, 2:23 AM

#

that might be blocking

#

the connection

mint roost Feb 11, 2020, 2:23 AM

#

I didnt see anything running on 7777. Is there another way to check whats running on it?

timid moss Feb 11, 2020, 2:24 AM

#

i mean in the terminal

#

not the ue4 one

limber gyro Feb 11, 2020, 2:24 AM

#

theres some CMD commands that i can not remember, if you have a svchost process running on 7777 its fine, anything else its gonna block connections

timid moss Feb 11, 2020, 2:24 AM

#

pretty sure its netstat -someoption

#

dont remember

limber gyro Feb 11, 2020, 2:24 AM

#

ye

mint roost Feb 11, 2020, 2:25 AM

#

I think svchost is running on something else. Last time i checked

#

Not port 7777

limber gyro Feb 11, 2020, 2:25 AM

#

svchost runs on a bunch of stuff its jsut how windows does things

timid moss Feb 11, 2020, 2:26 AM

#

only other thing i can think of is you didn't configure your frewall inbound rules corectly.

#

maybe try it again but this time completely turn off the firewall

limber gyro Feb 11, 2020, 2:26 AM

#

didnt he try disablign the firewal lalready?

mint roost Feb 11, 2020, 2:26 AM

#

Yep

limber gyro Feb 11, 2020, 2:26 AM

#

thats like the first thing people do usualy

timid moss Feb 11, 2020, 2:26 AM

#

man idk lol

mint roost Feb 11, 2020, 2:27 AM

#

I also do have rules setup for port 7777 one for tcp and udp

limber gyro Feb 11, 2020, 2:27 AM

#

y computers so uncooperative

limber gyro Feb 11, 2020, 2:27 AM

#

if you are connecting in lan you shouldnt eve nneed to portforward

mint roost Feb 11, 2020, 2:27 AM

#

Well people who arent on lan need to connect thats why

limber gyro Feb 11, 2020, 2:27 AM

#

does the server register any 1 tryign to connect at all?

mint roost Feb 11, 2020, 2:29 AM

#

When my brothers machine hosts im able to connect to his server on the 73.xx.xx.xxx ip (non local). But not when I host. He can't connect to me.

#

The 193.xxx.xx.xx ip works for both

#

Connecting to those work

limber gyro Feb 11, 2020, 2:29 AM

#

oh so the local works for both

mint roost Feb 11, 2020, 2:29 AM

#

Correct

limber gyro Feb 11, 2020, 2:29 AM

#

its because u gotta port forward for both then

#

u need to port forwarding rules

timid moss Feb 11, 2020, 2:29 AM

#

have u tried doing the same test but this time using a computer different from your brother's?

limber gyro Feb 11, 2020, 2:29 AM

#

1 for your brthers pc and another for urs

timid moss Feb 11, 2020, 2:30 AM

#

o and yeah that woulud be the problem. if its not yet port fowded

mint roost Feb 11, 2020, 2:31 AM

#

@timid moss not atm.
@limber gyro and it should be. I have same rules set on my pc that he does

limber gyro Feb 11, 2020, 2:31 AM

#

u dont set those rules on ur PC u set them on the router

#

login into your router and check your port forwarding rules

#

u gotta make 1 rule for each local IP

timid moss Feb 11, 2020, 2:35 AM

#

O. Another thing is that both computers can't fwd the same port. So one of them has to be 7777 and the other will have to be a different port. (me and my brother do 7777 and 7778). So if the computer who has the 7778 port is hosting, you got to make sure that it is listening on that specific port. So if your brother has his port fwd at 7778 then you would need to listen on 7778. But if your port is fwd at 7777 then make it listen at 7777

mint roost Feb 11, 2020, 2:35 AM

#

That might be it.

#

We're both connecting to same router

limber gyro Feb 11, 2020, 2:35 AM

#

oh i didnt know that

#

but it makes sense, the router wouldnt know to which PC to send the packets

mint roost Feb 11, 2020, 2:36 AM

#

Sorry 😅

dont b srry. every1 learns from somewhere

mint roost Feb 11, 2020, 2:37 AM

#

So then if that is the case, would we just need to set another rule within the router and set port to 7778?

limber gyro Feb 11, 2020, 2:38 AM

#

@plush mist its the car that jitters it seems, might be because the car is too fast and the server is trying to pull it back

#

you should try messing with the network settings specialy the distance that the server corrects

#

that would be my first gess

#

guess'

timid moss Feb 11, 2020, 2:39 AM

#

yeah pretty much

#

can u answer a quick question? who's computer has a port forwarded on 7777

mint roost Feb 11, 2020, 2:40 AM

#

Cause I think currently we're both forwarding to the same port. Therefore why im able to connect to him when he hosts and he cant when i host

plush mist Feb 11, 2020, 2:40 AM

#

@limber gyro ok. thanks. I am trying with low speed.

timid moss Feb 11, 2020, 2:40 AM

#

my router doesn't let me do 2 of the same ports

#

when forwarding

mint roost Feb 11, 2020, 2:42 AM

#

Gotcha. That has to be it for me then

#

Bc his i believe is port forwarding 7777

timid moss Feb 11, 2020, 2:42 AM

#

My guess is that only 1 of you have a port fwded at 7777. unless your router's options some reason lets you do 2 port fwding options on the same port. which in that case maybe it is just picking one of your computers to fwd to

#

ok that makes sense

mint roost Feb 11, 2020, 2:43 AM

#

If anyone's is port forwarded to 7777 its his

timid moss Feb 11, 2020, 2:43 AM

#

make yours 7778 TCP/UDP and find out whatever thing u need to do in UE4 to make sure your listening on 7778. So like figure out how to listen on a custum port number

Hey everyone - I'm trying to make a chatroom system where a player enters a chatroom, which then adds their player controller to a struct which is nested within a map with strings as the chatroom names. So when the player enters a chatroom it executes a server event that grabs the struct from the map based on the chatroom name, breaks the struct to reveal playercontroller array, and adds their player controller to the array. I've been trying different things for hours and I can't seem to get the controllers to be added to the playercontroller array. Any ideas?

#

Here's the blueprint from my PC:

#

And from the event within the game state:

@tribal solstice seems to me you need to "Add" your updated "S_ChatroomPlayerControllers" list to your Chatroomplayers map after 'finding' it

#

@tribal solstice because I think you're just modifying a copy of it.

#

Hello. Super network noob here, trying to understand the basics... Why would the player controller ID return '-1' for the second player here? If I tick 'RunDedicatedServer', they both show as '-1'. Ty

@coarse furnace That was the plan, but it seems like the PCs are not being added correctly. After the 'Add' node I do a read out of the contents and it does not show that there are any PCs inside.

rich ridge Feb 11, 2020, 8:23 AM

I have asked this question a way long back and I didn't get a good response, so I hope I do get a good answer now.

Let's assume I m connected to Dedicated server and playing the multiplayer game. Now if I want to show some ads on screen will that request be routed to Dedicated server and dedicated server will again talk to actual internet to serve the ads.

Why I m having this thought is I believe that once we connect to Dedicated server the whole Network driver is connected to that dedicated server.

So I have an issue where regular movement replication is interfering with a ladder system I made up. I tried disabling movement as soon as a ladder is mounted but for some reason this causes movement for that character to be just ridiculously fast

#

I know I will probably have to block input for the character movement component somewhere, but does someone know why it does this?

#

I'd expect it to just y'know not replicate

No other way

meager horizon Feb 11, 2020, 3:22 PM

#

if i connect a client to multiplayer dedicated server, can i then split screen that client, and have it introduce two players under one process?

#

is that a thing?

#

or in ue4 multiplayer is each client process purely one player, and splitscreen a local only thing

#

just curious, because if that did work, it would be a great way to let my kids all play on my dedicated server together, i only have two devices.

and three kids 😛

replication question

#

if i want to call a server function on the game state from the client do i need to go through the pc or can i just call it diretly

#

nvm dumb question the server owns the gamestate so i can't go to it directly

fleet raven Feb 11, 2020, 3:46 PM

#

you can connect a split screen client to a server and have two controllers for your one net connection yes

rocky totem Feb 11, 2020, 3:47 PM

#

zeb i'm not crazy right i do need to call the server function initally from the pc since the client doesn't own the gs correct?

fleet raven Feb 11, 2020, 3:48 PM

#

yes you can't call a server rpc on game state

#

send it on player controller or player state or something else your client owns

rocky totem Feb 11, 2020, 3:49 PM

#

ok good deal

#

just checking

fleet raven Feb 11, 2020, 3:49 PM

I hate this tbh

rocky totem Feb 11, 2020, 3:49 PM

#

hate what

fleet raven Feb 11, 2020, 3:50 PM

#

it would be so much nicer if you could have a ServerAny rpc type that lets everyone call it and you just get the controller that ran it as the first argument

rocky totem Feb 11, 2020, 3:51 PM

#

yeah i would agree it's annoying BUT i'm sure deep down there was a design reason i'm not experienced enough to see so imma just roll with it

I have MyActorComponent who is a member of MyPawn. MyActorComponent is set to replicate, and within it, I spawn MyActor which is also set to replicate, and is visible on all clients. The BeginPlay() Function in MyActor runs on all clients, however, when I call DoStuffFunctionA() on MyActor from MyActorComponent , it is only run on the server. If I call DoStuffFunctionB_Multicast() from the DoStuffFunctionA() it still only runs on the Server.

Where should I put a duration of the match that the game is taking place in? Is that in GameMode?
The reason I asked because if I put it in GameMode, then during the match, I'll have to continuously ping the GameMode (Server) to ask for what the current time is.
OR is there a better way of doing this?
Or should I tick the game time in GameMode, then write out the value into GameState, and then everyone can access it in GameState?

winged badger Feb 11, 2020, 6:31 PM

#

why would you need to ping the GameMode, does your GameState count down time at different speed?

tall pine Feb 11, 2020, 6:57 PM

#

no, not at all

#

I'm tasked with re-write GameMode and GameState, so I'm learning and removing code where they're not supposed to be

#

I'm trying to understand what should go into GameMode and what should go into GameState

#

So yesterday I ended up having the timer tick on GameMode, and just write the result to GameState so everyone can access it. Is that a good way to go about it?

rancid barn Feb 11, 2020, 7:39 PM

#

There isn't really a hard-and-fast rule. The various classes have different properties and virtual functions that make them better or worse at certain things

#

In the case your describing, I would imagine that the starting match time is set by the game mode and elapsed time tracked by GameState.

#

Or you could have your own UTimerTracker class of some sort that periodically updates the gamestate

#

depending on complexity

tall pine Feb 11, 2020, 7:45 PM

#

Yeah that's the trouble I'm facing, not knowing what to do in GameState vs GameMode

rancid barn Feb 11, 2020, 7:46 PM

#

You can ask this question: does X feature change depending on the game mode?

#

elapsed time is always going to be the same across every game mode you ever make. a second is a second

#

that will tend to suggest putting it on something else, in this case the time elapsed is very much part of the game state, intuitively

#

but the total time required for the match to end will vary depending on the game mode, so that suggests that's where it should be

tall pine Feb 11, 2020, 7:48 PM

#

so GameState is replicated to everyone, but its tick function only get called once?

rancid barn Feb 11, 2020, 7:49 PM

#

GameMode is server-only, GameState exists on all clients and is the most easily accessible global replicating class that clients can access

tall pine Feb 11, 2020, 7:49 PM

#

so there are N number of GameState, corresponding to N clients?

rancid barn Feb 11, 2020, 7:49 PM

#

There is one game state on each client

#

the same

#

gamestate

#

exists on all clients and server

#

There is one unique controller for each client, that only exists on that client and also the server

#

there is one gamemode, and that exists only on the server. Clients will never access it

tall pine Feb 11, 2020, 7:51 PM

#

So say since the client can have access to the GameState, if one client writes into a variable on his GameState, that will be replicated to other clients's gamestate?

rancid barn Feb 11, 2020, 7:51 PM

#

replication is a server-only concept

#

replication is defined as copying a server value to all clients

#

so if the server writes the score to gamestate, all clients can see it if it's replicated

tall pine Feb 11, 2020, 7:52 PM

#

so what happens when a client change a variable on the gamestate?

rancid barn Feb 11, 2020, 7:52 PM

#

then the client will see the variable only locally

#

if it's a replicated variable, it will sync with the server the next time the server modifies the value

#

so if a client changes it's score to 999, it will see 999 on a local-only basis (nobody else will see that.) The next time the server updates the score, the local 999 will be replaced by the replicated value

tall pine Feb 11, 2020, 7:54 PM

#

ok, that makes sense. I can now the match time can be in GameState instead of GameMode

#

what about logic decision making? Those should exist in GameMode?
Say for example, if I'm writing a racing game, and I want to know if a car can finish a race base on his current progress (number of laps), the number of laps should be stored in his player state? But the logic to determine that should be in GameMode?

winged badger Feb 11, 2020, 7:56 PM

#

it has to be in GameState to avoid timers jittering because of lag variance

#

its a matter of practicality, you don't constantly replicate the match time

#

which means GS needs to tick them down

#

because GM can't do that for clients

tall pine Feb 11, 2020, 7:58 PM

#

That makes sense.

rancid barn Feb 11, 2020, 7:59 PM

#

Win condition is generally a GameMode thing

winged badger Feb 11, 2020, 8:00 PM

#

i wouldn't put it in PS either

#

unless its there solely to be read by the UI

#

so when a player overtakes you he can have a widget overhead saying "3 laps ahead of you sucker!" or some such 😄

rancid barn Feb 11, 2020, 8:02 PM

#

basically playerstate is for private player information and gamestate is for public information, so if you put laps in playerstate, other players would be oblivious to how many laps everyone else has run

#

which may or may not matter

tall pine Feb 11, 2020, 8:04 PM

#

But we have a PlayerState array in GameState right? It seems logical to put the number of laps of each player in their corresponding PlayerState

rancid barn Feb 11, 2020, 8:05 PM

#

There is one unique PlayerState on each client (and also the server.) Clients cannot see other clients' PlayerStates

#

so if you wanted clients to be aware of how many laps each other client has run, you would not want to put it in PlayerState

tall pine Feb 11, 2020, 8:10 PM

#

but a client can ask the GameState for that info right?

rancid barn Feb 11, 2020, 8:10 PM

#

clients can access the GameState

tall pine Feb 11, 2020, 8:11 PM

#

so if I have a function say, MyGameState::GetNumLaps(AVehicle), and pass in a vehicle that I want to know about its current lap, inside GameState I can find that vehicle PlayerState, and return its lap

rancid barn Feb 11, 2020, 8:11 PM

#

negative

#

assuming it is a normal UFUNCTION(), if a client called that function, passing in someone else's vehicle, the GameState would try to GetLaps() from a gamestate that doesn't exist on that client, and you'd get nullptr and crash the game

#

if a client tries to access any PlayerState other than it's own, it will just get nullptr

#

the server can access any PlayerState it wants, of course

tall pine Feb 11, 2020, 8:14 PM

#

So only the server can call that function basically

rancid barn Feb 11, 2020, 8:14 PM

#

A client could call the function as long as it passes in its own vehicle, because the client has access to its own playerstate

#

the server would have full access, yes

tall pine Feb 11, 2020, 8:16 PM

#

I see, so back to the function that I asked about, to check if I can finish a race, that should be in GameMode then, since it's on the server

#

cause I can ask about any vehicle

rancid barn Feb 11, 2020, 8:17 PM

#

Yes, generally win conditions go in GameMode

#

because win conditions can vary depending on the game mode / settings

#

depending on the game, it could be setup in such a way that the player/pawn doing the winning could say "I win, right?" and poll the GameMode, which then confirms the win

tall pine Feb 11, 2020, 8:23 PM

ok, got it, thank you for your help Skyline and Zlo

rocky totem Feb 11, 2020, 9:45 PM

ok i got a doozy for you guys. I have two maps in the same project. in the first map. I can replicate perfectly between client and server. However, in the other if i change something on the server it only updates the server and if i change something on the client it also only updates the server. they both have the same world settings what the hell is going on?

Hi all, short question! I have a compiled dedicated server and want it to start a map so that my clients can join sessions. Unfortunately the node called "Create Session" requires a player controller, which the server does not have. How can i create a session on a dedicated server?

Hey all, quick question. Does anybody know if there is an inherent restriction in the Replay System that doesn't allow players to possess a Pawn while viewing the Replay? We're creating a VR training application where the play session is recorded, and then the player and trainer are transported to a "review" room within the same level where the scene plays back on a SceneCapture2D plane / screen, while the trainer and player inhabit new full-body avatars to view and discuss the player's performance. Currently, when we begin the Replay, the multiplayer session seems to be killed (including VOIP). Is there any way to use this system while maintaining control of a new "playback" Pawn, in full multiplayer mode, with VOIP enabled?

Hello Guys,
I set an actor to bOnlyRelevantToOwner = true; and only owner & the server can see that actor which is good, but when i try to use MeshComp->SetOnlyOwnerSee(true); i expect only client render the mesh but on both client & the host mesh is not rendering!

is there any documentation how to use QoS (https://docs.unrealengine.com/en-US/API/Plugins/Qos/index.html)

#

except this API

tall pine Feb 12, 2020, 9:39 AM

#

@rocky totem : so you run the same code, but on one map it works and on the other it doesn't?

meager horizon Feb 12, 2020, 10:32 AM

#

has anyone made a nice modern web ui for a linux ue4 dedicated server?

#

something that makes the log viewable at a glance, gives you a user count/user list perhaps, that you can run through apache or ngix?

#

i could probably make something simple that receives piped logs, and parses user join/part lines, but if someone else has already made something nice i wont waste my time later

coarse furnace Feb 12, 2020, 12:18 PM

Hi. Is there a way to have per-player collision in a local co-op game? Like a door is spawned once per player and only visible to them (that I can do with Only Owner See). Then one player could open his own door and go through it but the second player would still see his own door closed and collide with it(thus seeing the other player go through it but I'm fine with that) Ty.

thin stratus Feb 12, 2020, 12:19 PM

#

The door opening part you can route through the specific player via client rpc or rather just not multicast/replicate the change

#

The collision part is more tricky as the mesh on the server side would not block the second player anymore.

#

I would maybe just make 4 collision object types, player1 to player4 and then let the door block all 4 by default

#

And when the door opens you just set that specific type to be ignored on the door

#

Not sure if there is a less hacky solution

#

You could also ignore the door object on the specific player collision but then no door would block that player so not sure that's better

coarse furnace Feb 12, 2020, 12:23 PM

#

Yeah I would have preferred not making multiple collision channels but if I need to it's not that bad

#

The replication thing, I'm still new to this but wouldn't that just be relevant for server/client with lan/online sessions? I'm asking for local coop so there'd be only one single instance of UE running

thin stratus Feb 12, 2020, 12:24 PM

#

Ohhhh

#

Sorry

#

People ask so rarely about splitscreen/local stuff that i totally ignored that part

#

Ehhm

#

Yeah that's actually tricky

#

You might need to cheat that a bit

coarse furnace Feb 12, 2020, 12:25 PM

#

haha, yeah no worries. splitscreen's not that popular indeed 😄

thin stratus Feb 12, 2020, 12:25 PM

#

4 doors if you are unlucky

#

Set the owner to the player

#

And set owner only see on the mesh

coarse furnace Feb 12, 2020, 12:25 PM

#

yeah that's what I'm doing for the moment. One door per player with owner only see for visibility

thin stratus Feb 12, 2020, 12:25 PM

#

But not sure that works on other actors

#

Okay

coarse furnace Feb 12, 2020, 12:26 PM

#

but that doesn't solve the collision because both doors still lives in the game, right?

#

so there's two collision mesh (one for each door)

meager horizon Feb 12, 2020, 12:26 PM

#

how does unreal do map versioning? e.g. if i update the map on the server, do clients with an older map version get rejected, or does it just desync? do they/can they be shown a user friendly error message?

coarse furnace Feb 12, 2020, 12:27 PM

#

I was thinking of specifying a collision/object channel when I'm spawning a door for a particular player, like you mentionned above. It's not that bad I guess (if it works) but I was hoping not to flood my collisions channel with a bunch of 'PlayerX' channel

thin stratus Feb 12, 2020, 12:29 PM

#

Try to solve it first

#

And then check if you can improve it

coarse furnace Feb 12, 2020, 12:29 PM

#

Yup. Thanks for the help 👍

winged badger Feb 12, 2020, 12:46 PM

#

you could manipulate the player's collision responses on overlap if the player is also the owner @coarse furnace

coarse furnace Feb 12, 2020, 12:48 PM

#

@winged badger I'd still need one collision channel per player though right? Otherwise if player 1 owning the door would change door's collision, if would affect player 2 as well. So during the time player 1 go through the door, player 2 could go through as well. Or something like that I guess... not sure

winged badger Feb 12, 2020, 12:49 PM

#

no, you'd need one query channel that you can't turn off for all players and a box on the door to detect them

#

then on overlap if the otheractor == getowner you set its response to channel <whatever the doors physics collision is> to ignore

#

on end overlap you turn it back on

coarse furnace Feb 12, 2020, 12:50 PM

#

ohhh that way, I see

#

hmm interesting. I'm trying the multiple channel route for the moment and will try your approach if I'm not pleased with mine. Thanks for the suggestion

winged badger Feb 12, 2020, 12:52 PM

#

you could disable response to door as part of the action of opening the door, but can't count on the players to close it to reset players collisions

coarse furnace Feb 12, 2020, 1:35 PM

#

well, having two 'Player' object channels like Cedric suggested, works like a charm. I don't expect to support more than two players anyway so I'm fine with having just two object channels and it's actually quite trivial to implement. I have per-player visibility and collision working in splitscreen. Yay.

#

ty for the help 🤟

wary wyvern Feb 12, 2020, 2:32 PM

#

Does anybody knows, if it is possible to tear off not just single actor, but whole game? I need to shutdown a server process, but make clients stay on a same map with server's last state.

unique kelp Feb 12, 2020, 3:15 PM

#

Can a steam client successfully connect to a -nosteam server? Is it a matter of ignoring/providing my own unique net id? I assume it is possible somehow, but I would love a nudge in the right direction.

bitter oriole Feb 12, 2020, 3:24 PM

#

@wary wyvern No

wary wyvern Feb 12, 2020, 3:25 PM

#

@bitter oriole So there is no way to shutdown server and show some post-round results right after play?

bitter oriole Feb 12, 2020, 3:26 PM

#

That's possible, just not the way you think

#

You can copy the game state to another class every time it's updated, and show the post-round results in UI after disconnecting

wary wyvern Feb 12, 2020, 3:27 PM

#

But that way client will need to wait, until a map gets changed. That takes time

bitter oriole Feb 12, 2020, 3:29 PM

#

What do you mean by "map gets changed" ?

#

If the server was shut down, the client was disconnected at that point

#

Which you can handle with a travel to an empty map with a "post map results" game mode

wary wyvern Feb 12, 2020, 3:30 PM

#

Here is the reference I want to achieve.

https://youtu.be/p1OsjWOAV0M?t=617

When round ends, it shows u winner team and you can stay on that server until press next button

#

You can see the results right on the same map.

bitter oriole Feb 12, 2020, 3:32 PM

#

Then don't shutdown the server

#

Traveling to another map needs the server anyway

#

Server shutting down in UE4 will require a hard travel

wary wyvern Feb 12, 2020, 3:33 PM

#

So there is no way to stay on same map, but ignore server shutdown? Because it is possible when server crashes.

#

But I do not want to crash the server) I just want some kind of "tear off" functionality

bitter oriole Feb 12, 2020, 3:35 PM

#

Then no, there isn't that

wary wyvern Feb 12, 2020, 3:36 PM

#

Okay, thanks

bitter oriole Feb 12, 2020, 3:36 PM

#

Just keep your server running 10 seconds longer

#

Your players will be okay with not having the post-match state when the server crashes, anyway

wary wyvern Feb 12, 2020, 3:37 PM

#

@bitter oriole There is a catch with this one. Our game launcher tracks game end by process shutdown to read game results from a file.
If I make it stay, that way users, who leave a server faster won't see battle rewards.

bitter oriole Feb 12, 2020, 3:38 PM

#

I don't see the link here.

wary wyvern Feb 12, 2020, 3:38 PM

#

So I wanted to make clients stay as long as they want, but shutdown the process

bitter oriole Feb 12, 2020, 3:38 PM

#

Just write the file on shutdown

quaint tendon Feb 12, 2020, 3:38 PM

#

Brainstorm; How to add a physics based hover 'Add Force' that adds 'roughness'(irregularity) to the force but doesn't add so much that clients will be massively out of sync.

chrome bay Feb 12, 2020, 3:38 PM

#

perlin noise?

wary wyvern Feb 12, 2020, 3:39 PM

#

@bitter oriole As I said, players, who leave the server earlier, won't get their rewards. Rewards calculated using game result

chrome bay Feb 12, 2020, 3:39 PM

#

Anything that varies with time and affects movement is not easy to do @quaint tendon

wary wyvern Feb 12, 2020, 3:39 PM

#

One player can leave a second later, another player can stay for 30 seconds to see other players and game statistics

bitter oriole Feb 12, 2020, 3:40 PM

#

@wary wyvern I still don't see how that affects anything

#

That seems like a horrible way to get the results anyway

chrome bay Feb 12, 2020, 3:40 PM

#

If it's physics, doubt it'll matter though because in theory you're using client-auth anyway, or updates from the Server.

quaint tendon Feb 12, 2020, 3:41 PM

#

@chrome bay Agree, which is why I'm trying to think of an intelligent solution. Only needs to look like it's hovering but not so much the clients are out of sync.

chrome bay Feb 12, 2020, 3:41 PM

#

My suggestion would be a perlin noise LUT that you lookup with some kind of syncronised time variable

#

Use that to interpolate between a min and max force

wary wyvern Feb 12, 2020, 3:41 PM

#

@bitter oriole It is still a problem, that we have to hold a server until all the players leave it. We have like 1m DAU on other game, so that a lot of servers 4x4)

chrome bay Feb 12, 2020, 3:42 PM

#

Key part is making sure the time is in-sync, which is notoriously tough

#

Or, avoid it altogther and change the design 😄

wary wyvern Feb 12, 2020, 3:42 PM

#

It would be much better if we could cut our connection without making client to change a map

bitter oriole Feb 12, 2020, 3:42 PM

#

Well you can't

#

So work around it

wary wyvern Feb 12, 2020, 3:43 PM

#

Yeah, I'll try to find a way. Thanks anyway)

bitter oriole Feb 12, 2020, 3:43 PM

#

Or put a 10s limit and accept that 10 more seconds on a 10 minutes match is a 1.3% additional cost

#

Or show the results in a simple menu after the player has disconnected

quaint tendon Feb 12, 2020, 3:44 PM

#

@chrome bay The nature of the movement replication demands it's physics based. They only have to appear synced, the micro variations in force can be different as long as the location stays relatively the same.

bitter oriole Feb 12, 2020, 3:44 PM

#

Or use a separate map with 3D players

#

Lots of solutions

hoary lark Feb 12, 2020, 3:44 PM

#

"micro variations" smells like "use animations or other local visible fx" to me

chrome bay Feb 12, 2020, 3:44 PM

#

Using time to lookup a perlin noise value seems to be the way to me either way

#

But yeah, otherwise I'd suggest using an animation instead of actual physics.

split gust Feb 12, 2020, 3:45 PM

#

take a screenshot of the scene and use that as a background for the end result menu

wary wyvern Feb 12, 2020, 3:45 PM

#

@bitter oriole Yeah, I just thought there is an easy solution with "Tear off" functionality)

cerulean escarp Feb 12, 2020, 3:45 PM

#

@wary wyvern why not just have the player open the same map when disconnecting, and when the server shuts off have the results sent to the file then to the new map?

chrome bay Feb 12, 2020, 3:46 PM

#

If the only issue is the scoreboard/match result, why not just send all results to the client at the end of the match via RPC?

#

Then they can do whatever they want with it

cerulean escarp Feb 12, 2020, 3:46 PM

#

that too ^^

chrome bay Feb 12, 2020, 3:46 PM

#

Incidentally - that's what Gears 3 does. At the end of the match, if you leave the Server before the scoreboard is shown and return to the menu, the scoreboard shows there instead.

#

Game just keeps a "previous match" score hanging around

wary wyvern Feb 12, 2020, 3:47 PM

#

@cerulean escarp That way I loose all game statistics. I will have to manually save it to some other class.

cerulean escarp Feb 12, 2020, 3:48 PM

#

I would recommend doing Jamsh’s method

rocky totem Feb 12, 2020, 3:48 PM

#

and ideas why i can't join a session in a packaged game? void UNeoscapeHorizonsGameInstance::JoinIP(const FString& Address) { UE_LOG(LogNeoNetworking, Log, TEXT("Attempting To Join Session At:%s"), *Address); APlayerController* PC = GetFirstLocalPlayerController(); if (PC) { UE_LOG(LogTemp, Warning, TEXT("SUCCESSFULLY JOINED")); PC->ClientTravel(Address, ETravelType::TRAVEL_Absolute); } } there is the console command. it works just fine in PIE and if i use launch game but refuses to in a packaged game

wary wyvern Feb 12, 2020, 3:50 PM

#

I need to show statistics, all players, their equipment, names and stuff.
As I said, it could me much easier to leave clients with last server state and shutdown it. If it is not possible, than okay, just make another way to make it 🙂

solar stirrup Feb 12, 2020, 4:01 PM

#

Finally fixed my weird data using the serializer

#

turns out, if you don't give props a default value, you can get garbage in there

#

dunno why

chrome bay Feb 12, 2020, 4:03 PM

#

C++ das why

#

The engine usually warns you in the log if you haven't initialized properties

solar stirrup Feb 12, 2020, 4:05 PM

#

well at least I've got that in mind now ^^

chrome bay Feb 12, 2020, 4:05 PM

#

Another thing UE4 sort of hides from you a lot of the time

winged badger Feb 12, 2020, 5:17 PM

its not you can get garbage its you get garbage

solar stirrup Feb 12, 2020, 5:33 PM

:[

bitter oriole Feb 12, 2020, 5:43 PM

#

Yup

#

Part of why the language is used really

#

No stuff done behind your back

winged badger Feb 12, 2020, 5:45 PM

#

@solar stirrup as to why, you instantiate an object, it gets assigned a memory address in currently unused memory, your uninitialized vector is at N byte offset from the objects memory address

#

if you initialize it, that vector is written into that memory

#

if you don't, its value is whatever junk was there before

solar stirrup Feb 12, 2020, 5:46 PM

#

I see

#

thanks for explaining

meager spade Feb 12, 2020, 5:47 PM

#

you can see that behaviour if you use break points

#

sometimes you will see a pointer pointing to something different, till its assigned

#

its initalized, just not assigned

solar stirrup Feb 12, 2020, 5:47 PM

#

that's called a dangling pointer right?

meager spade Feb 12, 2020, 5:47 PM

#

instantiated*

#

no

winged badger Feb 12, 2020, 5:47 PM

#

you have a fair chance of uninitialized boolean having the value 0

#

its still junk memory

meager spade Feb 12, 2020, 5:48 PM

#

but yes

solar stirrup Feb 12, 2020, 5:48 PM

#

explains why I had bools with 17 or 250 as values

winged badger Feb 12, 2020, 5:48 PM

#

if it has the correct value, its purely by accident, ergo, you always get junk

meager spade Feb 12, 2020, 5:48 PM

#

dangling is normally if you had a pointer pointing somewhere, that object no longer exists, but the pointer never got updated.

#

pointers just hold a memory address, nothing more

tall pine Feb 12, 2020, 6:20 PM

Hi guys,

In GameState, we have the array of PlayerStates. Can a client see the PlayerState of other clients via this way?

#

Or does a client only be able to see his own PlayerState?

bitter oriole Feb 12, 2020, 6:36 PM

#

PlayerStates are replicated to all players

#

That's what they're for

tall pine Feb 12, 2020, 6:43 PM

#

so I can access other playerstates if I'm a client?

#

Wouldn't that cause cheating if I modify another player's playerstate?

#

Or will that only reflect locally and then get updated with server value next time we replicate

timid moss Feb 12, 2020, 7:39 PM

lol

rocky totem Feb 12, 2020, 7:39 PM

#

so the game mode has the following function

#


    //If this pawn is a player and is set to APC_NeoBase
    if (APC_NeoBase* PC = Cast<APC_NeoBase>(InController)) {
        return PC->GetPlayerPawnClass();
    }
    return DefaultPawnClass;
}```

#

and then the pc is the following fiasco

#

    TSubclassOf<APawn> CurrentPawnClass;

protected:
    UPROPERTY(EditDefaultsOnly, Category = "Classes")
    TSubclassOf<ANeoBase_Pawn> DefaultDesktopPawnClass;

    UPROPERTY(EditDefaultsOnly, Category = "Classes")
    TSubclassOf<ANeoBase_Pawn> DefaultVRPawnClass;

    UPROPERTY(EditDefaultsOnly, Category = "Classes")
    TSubclassOf<ANeoBase_Pawn> DefaultSteamVRPawnClass;
public:
        UFUNCTION()
    void SetPawnClass(TSubclassOf<APawn> InPawnClass);
    void DeterminePawnClass();
        UFUNCTION(BlueprintCallable)
    void Server_SetPawnClass(TSubclassOf<APawn> InPawnClass);
    UFUNCTION()
    void SetPawnClass_Internal(TSubclassOf<APawn> InPawnClass);
    UFUNCTION()
    void OnRep_PawnClass();

#

set pawn class is standard replication and determine pawn class i believe is where the magic happens

#

    //if the valid parameters for the HMD are not set then spawn desktop pawn
    if (IsLocalController()) {
        if (CanLoadVR()) {
            switch (GEngine->XRSystem->GetSystemName()) {
            case TEXT("SteamVR"):
                SetPawnClass(DefaultSteamVRPawnClass);
                break;
            default:
                SetPawnClass(DefaultVRPawnClass);
                break;
            }
            return;
        }

        SetPawnClass(DefaultDesktopPawnClass);
    }
}```

does this look half way logical

gleaming niche Feb 12, 2020, 8:35 PM

anyone here with experience with FFastArraySerializer? Either i've broken something, or those major changes in 4.23 have just.. screwed it up.
I recently upgraded to 4.24 from 4.22, and none of my serializers work properly anymore.
eg: in 4.22, it will never send a "Changed" event, without an "add" event first; even if you change relevency. it will always issue the add first.
in 4.24 (and i assume 4.23, since 4.23 is when the changes were made)
the add event will just.. not appear unless you're within netrelevency range when an item is added the first time?! has anyone else experienced this?

#

also, a huge difference between 4.22 and this, say for example you add something, change it, but then remove it shortly after (yes i know, it sounds like it's something that should be skipped if it happens, but I relied on this. in some cases, to ensure consistency between certain actions, based on what a human is actually doing. it's not something that would happen all the time, but is able to happen, and should be able)
in 4.23+ everything will just be dropped entirely

gleaming vector Feb 12, 2020, 8:46 PM

#

im in 4.24 and im noticing the events don't work

#

however i never had it working in the first place, so i was unsure if it was 4.24 or just me

#

but, hmm

#

it's working with the ability system

chrome bay Feb 12, 2020, 9:08 PM

#

@gleaming niche To be honest, even in 4.21 I found the event callbacks a bit suspect.

#

Just used it recently there and it's never quite accurate. I gave up in the end and used an OnRep Callback to do what I need instead.

#

Less than ideal.. but didn't investigate it much further than that

Anyone have any experience with Proteus? I'm having trouble building the .sln

cedar finch Feb 13, 2020, 12:49 AM

#

What is the correct way to replicate aiming your weapon? Right now I have a boolean called "bisAiming?" and a function called "SetMovementSpeed". The boolean when true plays the aiming animation inside my AnimBP and the function slows my movement speed. It works fine I just need to know how to replicate it so that there is not a lot of delay for clients when trying to aim. If I use the traditional switch on authority and then multicast in order to aim, clients sometimes have to wait a few milliseconds before aiming which isn't good.

#

I made this a long time ago and want to change it. https://i.gyazo.com/bffb00205a4b8cdc3ba1ca2e6d441101.png

meager spade Feb 13, 2020, 12:54 AM

#

@cedar finch aiming should be client side only

#

other players to see the aiming should just be a OnRep

#

set the bool to Rep Notify, condition Skip Owner

cedar finch Feb 13, 2020, 12:55 AM

#

exactly! Ok and put the update movement in there as well correct?

meager spade Feb 13, 2020, 12:55 AM

#

when you aim, tell the server to set bIsAiming to true, you as client set bIsAiming to true, you run the logic

cedar finch Feb 13, 2020, 12:55 AM

#

Ok Thanks. That makes sense

meager spade Feb 13, 2020, 12:55 AM

#

the OnRep will do anything the other clients need to see

#

no multicasts needed

cedar finch Feb 13, 2020, 12:55 AM

#

Ok cool. 🙂

#

Good lol I had way too many

meager spade Feb 13, 2020, 12:55 AM

#

multicasts == one off event

#

aiming is not one off

cedar finch Feb 13, 2020, 12:56 AM

#

True lol

meager spade Feb 13, 2020, 12:56 AM

#

like a explosion, is a one off event

any ideas why findsessions would be incapable of finding session on the local network with OSSNull

rich ridge Feb 13, 2020, 8:03 AM

#

@proper idol you can create a session on server even though it doesn't have player controller. There is another version of create session which takes userId, if your userId is NULL, the pass 0

#

Sessions->CreateSession(*UserId, SessionName, *SessionSettings);

#

In case it is your server pass 0 into your UserID

I don't know about Blueprint version, but this is how I have been doing from C++

Hello every one! I stuck with strange problem:
I do shooter, so I need to fire projectile from a weapon(on fire event from client, server spawns projectile in weapon's bullet_spawn socket position),
everything works fine in Editor with Dedicated server and multiple clients.
But when I compile Dedicated Server(NO HOST client) and connect to it, all projectiles spawn wrongly, 2-3 meters away from the point where they should, also their rotation is not as it is in Editor. I can't figure out what is wrong, and it is very difficult to debug. Any ideas?

#

any ideas why findsessions would be incapable of finding session on the local network with OSSNull
@rocky totem I think it highly depent on network where you host, maybe port which the host is using is blocked. You can check it by open level **ip_of_host**

winged badger Feb 13, 2020, 8:53 AM

#

@ivory flame i'd guess is that you didn't initialize a vector or a rotator somewhere

#

packaged builds won't go out of their way to do that for you like editor builds do

ivory flame Feb 13, 2020, 9:06 AM

#

Found that it is of T-pose and disabled animation on server(Strip Animation Data On Server is ON). But still, why the editor version DS works fine?

gleaming niche Feb 13, 2020, 9:07 AM

#

editor isn't exactly the same as a real dedicated server, i think you need to take of fhte option of running in the same memory space. that's actually bit me in the ass before when testing, thinking something was working when it only was because of that.

ivory flame Feb 13, 2020, 9:11 AM

#

@gleaming niche you mean always build server to test it?

hey, does anybody know where dedicated servers and clients check for different version numbers?

#

PossessedBy is only called on the server. you probably want to use an OnRep call from there to trigger the client, your best bet would likely be OnRep_Controller or OnRep_PlayerState

#

The Replicated tag only causes a property to replicate when changed, correct?

regal relic Feb 13, 2020, 8:51 PM

#

Yes. Silently.

#

If you need a changed replicated variable to trigger a function or event. You can use RepNotify.

pallid token Feb 13, 2020, 8:57 PM

#

Ok, so I have a TArray of actors that is replicated, the Actors are replicated within their own class, so the replication only needs to populate the TArray with the Actors that already exist. First replication, it populates with a few of the actors, and several nullptrs. It seems to replicate until all of the Actors are replicated and there are no more nullptrs. Is this observation correct?

cedar finch Feb 13, 2020, 11:12 PM

#

Ok I have a quick question. When I pickpup a weapon I run a Pickup Function that sets my weapon variables locally for that client, Then I run that same function again only "OnServer" and set an OnRep variable which is supposed to tell all other players what gun I just picked up. I put a print string inside the OnRep Function, But for some reason it's only printing for the client that is picking up the weapon, and the Server. Nobody else is recieving the info. What am I missing?

cedar finch Feb 14, 2020, 1:24 AM

#

Ok so I put that other issue on hold and now I have another question. I'm trying to hide my player name widget component from my self. It works for clients but the Server player is hiding everyones names. Here is my logic flow: BeginPlay-->>ServerSetVisibility Event-->>Sets OnRepBoolean-->>That boolean's replication condition is set to OwnerOnly. Then the OnRepFunction sets the visibility of the widget component. See below how the server on the left can't see anyones names, But clients can see everyones but his own. How do I fix the Server player to do the same? https://i.gyazo.com/d6a32547a62f93098f2cf3cad0fe53eb.jpg

stark hull Feb 14, 2020, 3:28 AM

#

Hi, I have an architectural question. Say for example I have 2 opposing teams and each player has specific traits for that team (they are visible via a 3D widget in the world). Thus, those traits should only be visible to members of one team. How would I go about implementing the 3D widgets so that the team members can see each other's traits, but not the other team?

#

The way I've thought about this - is 1) to spawn 3D widgets locally on the client and populate the fields of that widget with the available data to the client through the replicated player states of other players. I would make a look up of the other player's role and if it matches the controlled player's role, the widget would be spawned, otherwise check the next player

#

I'm also thinking of 2) using the server to call a ClientFunction to loop through all the other pawns and show/hide the widgets per player team

winged badger Feb 14, 2020, 6:09 AM

#

i find it easier to put the widget itself on a PlayerState Actor

#

and attach the PS to the Pawn

#

then each PS just needs to compare its TeamID with the local Player's TeamID and adjust visibility on (parts of the) widget on BeginPlay

#

@stark hull

stark hull Feb 14, 2020, 6:12 AM

#

@winged badger thank you for the reply. When you say "attach" the PS do you mean have a reference to it?

winged badger Feb 14, 2020, 6:13 AM

#

i mean physically, AttachToActor/Component

#

so that the PS Actor has the same position as the Pawn it belongs to

stark hull Feb 14, 2020, 6:13 AM

#

ow I see, makes sense ja

#

Thank you @winged badger

winged badger Feb 14, 2020, 6:17 AM

#

you would probably need to have TeamID in the controller as well as PS, just to be safe

#

as there is no guarantee your PlayerState replicates over first

#

but the controller will be there before the PlayerStates replicate

#

delayed start would also work to ensure order

#

its not a big deal, bandwidth wise, one byte per player in a match

stark hull Feb 14, 2020, 6:20 AM

#

In my case, the UI element I would want to show is far away from begin play. Just to give more context: the players have a "warm up" 10 second timer and only after that I show which team they got randomly assigned to

winged badger Feb 14, 2020, 6:20 AM

#

then you don't have a problem there

#

the potential for race is only if the PlayerStates can call BeginPlay immediately as they replicate over

#

and need to set the team inside of it

stark hull Feb 14, 2020, 6:22 AM

#

gotchu, I think I'm safe then hah, thanks again @winged badger

winged badger Feb 14, 2020, 6:23 AM

#

be wary of of this abomination

#

    /** Return true if FindPlayerStart should use the StartSpot stored on Player instead of calling ChoosePlayerStart */
    virtual bool ShouldSpawnAtStartSpot(AController* Player);

#

it has the tendency to force players to respawn at the first PlayerStart that got assigned to them upon connecting

#

(GameModeBase) @stark hull

stark hull Feb 14, 2020, 6:25 AM

#

Ow yeah I ran into it earlier once I figured out the "round" logic loop, it was annoying to debug

winged badger Feb 14, 2020, 6:26 AM

#

that function has been known to cause problems in setups where team is not known at the time you load the map

#

if you just override it to return false, you can run find/choose playerstart normally each time

cedar finch Feb 14, 2020, 6:28 AM

#

I'm having a similiar issue with players that load in or join into my game late and cannot see other players Names above their heads. I have a widget component in my ThirdPersonCharacter bp that displays the name. I've tried every way I can think of to replicate it using OnRep so that maybe people will see it if they join late. What is the best approach? I'll redo my approach to whatever works. I'm just wanting to learn the right way to do it. Ideas?

winged badger Feb 14, 2020, 6:30 AM

#

if its always visible to all players

#

it just comes to having the component on the TPC CDO

cedar finch Feb 14, 2020, 6:31 AM

#

My bad, I forgot to specify. So they can see the widget, the actual Name variable is not being set

winged badger Feb 14, 2020, 6:31 AM

#

and having it feed the name to the widget and set visibility on it on BeginPlay

#

which is in PlayerState, right?

cedar finch Feb 14, 2020, 6:32 AM

#

Correct I have a custom Name variable in Playerstate. I don't use the default one because I let players change their name in-game

winged badger Feb 14, 2020, 6:32 AM

#

the PlayerName

#

you can rename the vanilla name as well, its just very awkward from BP

#

need to do it via GameMode call

#

there is c++ involved in this?

cedar finch Feb 14, 2020, 6:33 AM

#

I couldn't get it working a long time ago that's why I did my own variable. I don't want to use any c++ for this.

winged badger Feb 14, 2020, 6:34 AM

#

OnRep_PlayerState is the ideal hook for this

#

and its not BP accessible

#

(one on the Pawn)

thin stratus Feb 14, 2020, 6:34 AM

#

@cedar finch The picking up of the weapon, where are you calling that rpc?

winged badger Feb 14, 2020, 6:35 AM

#

aside from that you can have the PlayerState grab the Pawn on its BeginPlay and tell it "here is your name, tell the widget about it"

#

PlayerStates by default take a little while longer to replicate then the Pawns/Controllers

#

so while the Controller and Pawn have a good NetGUID for the PS by the time they call BeginPlay, the PS Actor hasn't replicated yet, and the NetGUID cannot be resolved yet

thin stratus Feb 14, 2020, 6:38 AM

#

Iirc this name above head is just annoying cause of epic not exposing stuff to bps. A combination of PlayerState::BeginPlay and Pawn::OnRep_PlayerState solves this really quickly, but the OnRep doesn't exist in BP ,right?

winged badger Feb 14, 2020, 6:38 AM

#

ofc it doesn't

thin stratus Feb 14, 2020, 6:39 AM

#

😹

winged badger Feb 14, 2020, 6:39 AM

#

i personally prefer to put those widget components on the PS itself

#

and attach the PS to Pawn

thin stratus Feb 14, 2020, 6:39 AM

#

Fair solution

#

I can't stress enough how important it is to allow cpp in multiplayer games. Even if you code the whole game in BPs, you should always allow yourself to have an empty cpp parent class which allows you to expose stuff like the OnRep to BPs. Takes 5 min and the problem would be solved.

cedar finch Feb 14, 2020, 6:41 AM

#

@winged badger So I'm down to do that if there isn't another way. Right now my gamemode creates the new player then that event calls the player controller event that sets the playerstate Name variable. Man this seems more complicated than it has to be lol
@thin stratus lol let me get this name thing working then we can go back to the pickup weapon.

#

https://i.gyazo.com/da80018ab9f2cde1c89b128e35db6a5d.png

#

That's the event in gamemode

thin stratus Feb 14, 2020, 6:42 AM

#

Why do you set the playerState name by hand?

#

Oh do I misunderstand?

winged badger Feb 14, 2020, 6:42 AM

#

he lets players rename themselves

thin stratus Feb 14, 2020, 6:43 AM

#

But epic has a function for that 🧐

winged badger Feb 14, 2020, 6:43 AM

#

and BP solution for that is insanely awkward

#

you have to call it on the GameMode

thin stratus Feb 14, 2020, 6:43 AM

#

Yeah but that's like 3 nodes extra

cedar finch Feb 14, 2020, 6:43 AM

#

I let the player edit their profile then save it to file. Name is one of those

thin stratus Feb 14, 2020, 6:43 AM

Probably not even cause you save the playerstate nodes

this is more of a #cpp question, and without an error, no idea

thin stratus Feb 14, 2020, 6:46 AM

#

Cause that parameter is probably not a bp one :D

cedar finch Feb 14, 2020, 6:47 AM

#

So I have gamemode, playercontroller, playerstate, and playercharacter. lol You said I need to either RepNotify the Name variable inside playerstate. Or I could attach the playerstate to the playercharacter?

thin stratus Feb 14, 2020, 6:47 AM

#

You can't expose that steam variable to bps @gritty pelican

#

You need to make your own type and convert the steam one to it

#

Or wrap it into a struct at least

winged badger Feb 14, 2020, 6:48 AM

#

idea about attaching the PS to Pawn is basically

#

widget is using the PS as a Context, it has all the information widget is supposed to be displaying

gritty pelican Feb 14, 2020, 6:48 AM

#

struct FSteamInventoryFullUpdateResult
{
GENERATED_BODY()

SteamInventoryFullUpdate_t Value;

};``` right? @thin stratus

winged badger Feb 14, 2020, 6:49 AM

#

but being a widget on a WidgetComponent, where the widget is rendered depends on where that component is

cedar finch Feb 14, 2020, 6:49 AM

#

My ghetto way of setting the player names works until someone loads/joins late. Basically I have the playername in my playercontroller. It sets the variable inside playerstate. I just don't know what to do next

winged badger Feb 14, 2020, 6:49 AM

#

and thats why you attach the PS, so it keeps the same location as the Pawn at all times

#

with the WidgetComponent being on the PS, not the Pawn

gritty pelican Feb 14, 2020, 6:50 AM

#

and delegate DECLARE_DYNAMIC_MULTICAST_DELEGATE_OneParam(FOnSteamItemsLoadedDelegate, FSteamInventoryFullUpdateResult, Result);

cedar finch Feb 14, 2020, 6:50 AM

#

What happens when the player dies and gets destroyed?

winged badger Feb 14, 2020, 6:50 AM

#

it will compile, but be completely useless from BP as far as parameter goes

cedar finch Feb 14, 2020, 6:50 AM

#

Does his name just float there?

gritty pelican Feb 14, 2020, 6:50 AM

#

i dont need bp

#

only c++

winged badger Feb 14, 2020, 6:51 AM

#

then just lose the DYNAMIC from the delegate

#

it won't be even visible from BP, and it will run faster, and no need to wrap anything

gritty pelican Feb 14, 2020, 6:52 AM

#

I need dynamics, as I will convert the structure to int in the future in BP

winged badger Feb 14, 2020, 6:52 AM

#

you just said "i don't need BP"

#

but if you do

#

then that wrapper struct should take the steam type in the constructor

#

and do the conversion to int, stash that into a BlueprintReadOnly UPROPERTY

#

problem with that is steam params converted to int usually translate into uint64, which BP does not support

gritty pelican Feb 14, 2020, 6:55 AM

#

it int32 value

#

SteamInventoryFullUpdate_t

cedar finch Feb 14, 2020, 6:56 AM

#

@thin stratus So my pickup weapon is called in my player character. If your not the server then the server runs the pickup again. https://i.gyazo.com/d88d6c7664873bae37aeca5776a4961c.png
https://i.gyazo.com/2338fc33eb40402a817766c4345f3011.png
Clients can see the new weapon they picked up but everyone else still see's the same weapon.

winged badger Feb 14, 2020, 6:57 AM

#

then add the UPROPERTY(BlueprintReadOnly) int32 Value; Rename the steam type, add a

FSteamInventoryFullUpdateResult(SteamInventoryFullUpdate_t InValue)
{
  Value = ConvertToInt(InValue):
}

cedar finch Feb 14, 2020, 6:57 AM

#

I put the actual changing of the weapon mesh and the animation iside an RepNotify but it's only showing for that client and the Server. https://i.gyazo.com/f95d6bc56577c09c9bca1dc78902f258.png
https://i.gyazo.com/0c49c8a42737ddbcb48f9c17ea7431a6.png

#

IDK basically I'm asking "If I set a RepNotify" variable while "OnServer" why does it not replicate to everyone? Usually it does". I may just step back and think about it. Feel free to message me or ping me if you have ideas.

gritty pelican Feb 14, 2020, 6:59 AM

#

struct FSteamInventoryFullUpdateResult(SteamInventoryFullUpdate_t InValue)
{
    UPROPERTY(BlueprintReadOnly) 
    int32 Value;
    Value = ConvertToInt(InValue);
}``` right?

#

@winged badger

winged badger Feb 14, 2020, 7:01 AM

#

no idea is to do

#

OnSteamInventoryUpdate.Broadcast(FSteamInventoryUpdateResult(InSteamTypeValue));

#

for that struct needs to have a constructor that takes steam type, converts it to int and sets it

#

which is what i wrote above

#

it still needs the GENERATED_BODY and all that

#

and the actual ConvertToInt function

gritty pelican Feb 14, 2020, 7:03 AM

#

Okay, STEAM_CALLBACK(ACPP_DesertPlayerController, OnSteamInventoryFullUpdate, SteamInventoryFullUpdate_t, OnSteamInventoryFullUpdateCallback); I try to make this work as well, but I get a lot of errors.

#

and I don’t know how to properly bind the delegate in the constructor OnSteamInventoryFullUpdate.AddDynamic(this, &ACPP_DesertPlayerController::OnSteamInventoryFullUpdateCallback);

#

{
}```

#

    FOnSteamItemsLoadedDelegate OnSteamInventoryFullUpdate; ```
Should I indicate the name of the function or callback? OnSteamInventoryFullUpdate or OnSteamInventoryFullUpdateCallback?

#

I spent 6 hours, I didn’t understand anything

thin stratus Feb 14, 2020, 7:09 AM

#

I usually call them OnSteamInventoryFullyUpdated so basically some past tense.

#

The problem is basically that you are using a DELEGATE version that can be exposed to BPs.
And cause of that you are limited to types that BPs understand.
So if you wish to use SteamInventoryFulUpdate_t then you have to wrap it into a struct that BP can understand.
If you don't want to expose this to BPs, then you can just keep the SteamInventoryFullUpdate_t in the struct and that's it.
Cause you can just grab it in C++ and work with it.

If you however want to expose it to BPs, then you need to add functions that use the struct and access the inner Steam variable to return information that BPs can understand.
That's the overall "way" of exposing non-BP types.

    FSteamInventoryFullUpdate(SteamInventoryFullUpdate_t* InValue)

That shoud be enough to work with it.

STEAM_CALLBACK(ACPP_DesertPlayerController, OnSteamInventoryFullUpdate, SteamInventoryFullUpdate_t, OnSteamInventoryFullUpdateCallback);Am I calling this correctly?

#

and this DECLARE_DYNAMIC_MULTICAST_DELEGATE_OneParam(FOnSteamItemsLoadedDelegate, FSteamInventoryFullUpdate, Result);

thin stratus Feb 14, 2020, 7:16 AM

#

If you later need this in BP then you can do this:

UFUNCTION(BlueprintPure, Category = "Steam")
static bool GetSomeBoolFromSteamInventoryFullUpdate(const FSteamInventoryFullUpdate& InBPSteamStuff);

bool UYourLibrary::GetSomeBoolFromSteamInventoryFullUpdate(const FSteamInventoryFullUpdate& InBPSteamStuff)
{
    return InBPSteamStuff.SteamValue->GetSomeBool();
}

#

Not sure if that thing holds any boolean info, just an example

#

Am I calling this correctly?
Don't know. Does it compile?

#

The delegate looks fine

gritty pelican Feb 14, 2020, 7:17 AM

Not sure if it's needed if you don't expose anything. I hate these macros because half the time I forget when/what/where they do.
Add it, just to be sure.

gritty pelican Feb 14, 2020, 7:22 AM

{

thin stratus Feb 14, 2020, 7:23 AM

The STEAM_CALLBACK one? Honestly, no idea. I touch that every 12 months once or so.

gritty pelican Feb 14, 2020, 7:24 AM

Yes, I only need one STEAM_CALLBACK to get the entire list of items from the Steam inventory

Looks like a member function is used.

#

So if you define this outside of the header/class, you have to put the class name infront of it.

idk then, something weird is going on here

marble depot Feb 14, 2020, 11:49 AM

#

hey, I have a weird problem with my servers. they suddenly stopped connecting to Steam. they spam out [S_API FAIL] SteamAPI_Init() failed; SteamAPI_IsSteamRunning() failed. [S_API FAIL] SteamAPI_Init() failed; unable to locate a running instance of Steam, or a local steamclient.so.
they've been running for months with no problem whatsoever. nothing changed on my side, maybe a Valve API change? i haven't been able to get it working at all. any help? thanks

winged quail Feb 14, 2020, 12:03 PM

#

@marble depot i think you have 2 instances open on the same machine

marble depot Feb 14, 2020, 12:03 PM

#

nope

winged quail Feb 14, 2020, 12:04 PM

#

checked in task manager?

#

and is this on local machine or deployed server?

marble depot Feb 14, 2020, 12:04 PM

#

i have tested on multiple servers, there aren't multiple instances on the same port. there is a different message the server gives when this is the case

#

deployed dedicated server

winged quail Feb 14, 2020, 12:05 PM

#

is steam running and signed in?

marble depot Feb 14, 2020, 12:06 PM

#

do you mean on the client? yes

winged quail Feb 14, 2020, 12:06 PM

#

not client. Server

marble depot Feb 14, 2020, 12:06 PM

#

it's a server, it doesn't work like that

winged quail Feb 14, 2020, 12:06 PM

#

last time i checked u needed stream running

#

🤔

#

are u sure?

marble depot Feb 14, 2020, 12:07 PM

#

you need the steamclient.so (or dll if you're on windows) and then the server uses that to connect to steam

#

i mean unless something changed on valve's side in the last month, yes. i've been doing this process for almost two years without problems

winged quail Feb 14, 2020, 12:10 PM

#

@marble depot so what ur saying is if you don't put steamclient.dll you could use steam (client) to connect?

marble depot Feb 14, 2020, 12:11 PM

#

if you don't give the server the library, it won't be able to connect to steam

#

and the obvious question is: do i have a steamclient.so along the server binary? yes i do

winged quail Feb 14, 2020, 12:11 PM

#

[S_API FAIL] SteamAPI_Init() failed; unable to locate a running instance of Steam, or a local steamclient.so.```

#

ok so if steamclient.so fails why don't u try to download steam and sign in and test

marble depot Feb 14, 2020, 12:12 PM

#

what do you mean by that

winged quail Feb 14, 2020, 12:12 PM

#

do u connect via ssh?

marble depot Feb 14, 2020, 12:13 PM

#

it's a headless production server, yes

winged quail Feb 14, 2020, 12:13 PM

#

i mean if u can see the gui of server then you can download steam from website and sign in and try it

#

because i see only 2 reasons it wouldn't work

marble depot Feb 14, 2020, 12:14 PM

#

that won't work. the server uses a separate client. i remember doing that when first learning how dedicated servers work, and that doesn't work

winged quail Feb 14, 2020, 12:14 PM

#

unable to locate a running instance of Steam: which i did 2 years ago and it worked

split gust Feb 14, 2020, 12:14 PM

#

In most cases, you'll want your dedicated server to be able to run in anonymous mode so that you don't need the Steam Client or a specific Steam user to be signed in to run it. So, when you use the controls to release your tool, the dedicated server appID and associated depot(s) will automatically be added to the anonymous steamcmd package (pkg 17906) to be downloadable using SteamCMD in anonymous mode.

The appID will get marked as 'released' so that you can actually run the server via SteamCMD.

marble depot Feb 14, 2020, 12:15 PM

#

my game is released and i have an appid of my own

winged quail Feb 14, 2020, 12:15 PM

#

@split gust ah yes i remember that.

#

shootie i think you misunderstood

split gust Feb 14, 2020, 12:16 PM

#

did you add the steam_appid.txt file?

marble depot Feb 14, 2020, 12:16 PM

#

yep

winged quail Feb 14, 2020, 12:16 PM

#

run it in anonymous mode

marble depot Feb 14, 2020, 12:17 PM

#

how would i do that?

#

i just run the script unreal generates

winged quail Feb 14, 2020, 12:18 PM

#

i don't remember. try -anonymous as extra arguments

split gust Feb 14, 2020, 12:18 PM

#

maybe -login anonymous

crude sparrow Feb 14, 2020, 12:18 PM

Hi there, anyone know what is the best way to deploy a server that can be available for chinese people? We are currently hosting on Amazon Virginia but it seems to be blocked in China

#

or -log -AUTH_LOGIN=anonymous

marble depot Feb 14, 2020, 12:20 PM

#

just tried, not working

winged quail Feb 14, 2020, 12:20 PM

i think -AUTH_LOGIN=anonymous should work. Remember doing something similar

Steam Dedicated Server for Unreal Engine 4.19.2

In this tutorial, you will learn how to build a dedicated server for Steam using Unreal Engine 4.19.2.

I know that another guy made a video about it, but it didn't work for me, so I decided to do a tutorial when I fix all the problems I had.

My tutorial notes and screenshot...

i know that tutorial, what exactly should i be looking at?

#

that is exactly what ur trying to do

#

maybe you messed something up?

marble depot Feb 14, 2020, 12:28 PM

i haven't changed anything in the last 3 months

winged quail Feb 14, 2020, 12:28 PM

marble depot Feb 14, 2020, 12:28 PM

and then one day it just stopped working

winged quail Feb 14, 2020, 12:28 PM

#

u tried restarting vm instance?

marble depot Feb 14, 2020, 12:29 PM

#

at first i thought it was the server they were running on, so I changed to another server I had and surprise surprise it still wasn't working

winged quail Feb 14, 2020, 12:29 PM

#

can u post ur full server log?

marble depot Feb 14, 2020, 12:29 PM

sure, hang on a minute

winged quail Feb 14, 2020, 12:37 PM

@marble depot i don't see anything wrong with it

#

also there is no trace of unable to locate a running instance of Steam error

marble depot Feb 14, 2020, 12:38 PM

i see it suppresses some errors

#

in the actual console log it shows them

just copy paste console log

winged quail Feb 14, 2020, 12:41 PM

you should have a testing server. It just makes your life easier

anyways i see this online: https://github.com/FezVrasta/ark-server-tools/issues/677#issuecomment-265275928

GitHub

[S_API FAIL] SteamAPI_Init() failed; SteamAPI_IsSteamRunning() fail...

Hello, The server is running pretty fine, but i got this message in /var/log/arktools/arkserver.log : 2016-12-06 14:03:44: start 2016-12-06 14:03:44: Running /home/steam/ARK/ShooterGame/Binaries/Li...

marble depot Feb 14, 2020, 12:42 PM

#

yes, it can be ignored when the server actually works. it spits it out from time to time, but it still works. not on this occasion though

winged quail Feb 14, 2020, 12:42 PM

#

maybe something else is at fault

marble depot Feb 14, 2020, 12:43 PM

#

i have testing servers. linux testing servers. if it would work on windows, but not linux, what would i even be doing then

winged quail Feb 14, 2020, 12:43 PM

#

Issue #626 is open for the new build failing with the symlink issue, the solution is to update to the latest steam.deb http://repo.steampowered.com/steam/archive/precise/steam_latest.deb then TF2 and the client is ok.

#

saw this online too thats why i think error is related to linux

marble depot Feb 14, 2020, 12:43 PM

#

is it a recent issue?

winged quail Feb 14, 2020, 12:44 PM

#

have you tried updating to latest steamclient.so ? Idk mabye that will break everything

#

is it a recent issue?
@marble depot no its from 2013. But at this point I can't offer more solutions

marble depot Feb 14, 2020, 12:44 PM

#

yeah, I tried using both the old steamclient.so i've been using for months and the latest one. same result

coarse furnace Feb 14, 2020, 1:39 PM

Hello. To be sure, I don't think it's possible to do a local split-screen coop experience where players can be in different levels, right?

#

Unless I use level streaming maybe? (but I don't intend to)

meager spade Feb 14, 2020, 2:21 PM

#

ue4 server doesn't support different levels

#

nor split screen

marble depot Feb 14, 2020, 3:32 PM

#

update: I have compiled another linux server and tested it on a few machines (ubuntu + centos). same exact result... honestly i'm at a loss. i can't understand how with absolutely no change they stop working and i can't get them working again...

sonic comet Feb 14, 2020, 4:02 PM

#

@marble depot The steamapi_init call should give some error information on the 'output' channel, which I believe you can only see with a debugger like visual studios attached to the process. Trying to get that info might help

marble depot Feb 14, 2020, 4:24 PM

#

this is good to know, but I don't think i can link a debugger to VSCode on linux (because there's no visual studio on linux) and get the server to launch through the debugger. unless i can replicate the exact same problem with a windows server

raven trench Feb 14, 2020, 4:25 PM

I've been reading through the network compendium, and trying to understand this diagram, as I'm doing my best to understand and adopt best practices for multiplayer PvP.
I'm struggling a little to know what goes where between the player controller and player character. Say I was making a melee PvP game, why would I not just put all movement and attacks etc in the player controller? Sorry if this is basic shit.

📎 unknown.png

half jewel Feb 14, 2020, 4:26 PM

#

like input ?

#

logic for melee attacks should be on the character (pawn)

#

and input and control for the character should be on the player controller

#

playercontrollers dont exist on other players machines so you cant replicate stuff if all ur logic is on PC

raven trench Feb 14, 2020, 4:27 PM

#

appreciate the quick response mate, really appreciate it

#

the reason I struggle to fully understand that is because surely each client sees other clients movement, so why would having the attacks on the controller not behave the same?

half jewel Feb 14, 2020, 4:29 PM

#

because the controller does not exist on their machines

raven trench Feb 14, 2020, 4:29 PM

#

apologies, just doing my best to fully understand

half jewel Feb 14, 2020, 4:29 PM

#

the server has no way to tell those clients whats going on

#

the thing doing the melee attacks is the player character its what everyone would see so its better to do all logic there

#

from a programming standpoint and a ue4 networking standpoint too

raven trench Feb 14, 2020, 4:31 PM

#

ok I get that, but why I'm confused is because you said control for the character should be on player controller. So you mean controlling like movement and jumping? Or should all that be on character too?

half jewel Feb 14, 2020, 4:32 PM

#

depends on a bunch of things

#

usually better to leave input on the character side

#

in case you would have multiple types of characters with different possible inputs in the future

#

playercharacters can handle input by themselves

#

without needing the playercontroller to pass input threw

raven trench Feb 14, 2020, 4:35 PM

#

ok, think I'm getting it. Basically, I can't go too wrong by putting player movement and attacks on the character?

half jewel Feb 14, 2020, 4:38 PM

#

so to make things more clearly, the playercontroller is that players relationship to the server and only the server. its a server<->localClient relationship. so really heavy stuff like loading the players progress on the server can be done in PC. it will remain forever for aslong as the player remains connected.

the playercharacter on the other hand exists on everyones machine. so the server can run code on every1's machine... aka seeing the player character do a melee swing because the server willed it to be so based on the owning players input. These characters are not permanent. they die, they can be destroyed (if thats wat happens in ur game).

#

that being said you can do w/e you want in the playercharacter, if you can control its volatility when it "dies" in your melee game.

raven trench Feb 14, 2020, 4:40 PM

#

mate thank you so much for that! You're a lamb! Really appreciate you taking the time to explain it

#

for some reason I was under the impression putting things in the player character made it easier for people to cheat, so was trying to do everything in the controller

half jewel Feb 14, 2020, 4:42 PM

#

not at all, the server will remain authoritive. players cant use another playercharacter to send commands to the server on its behaf. because they are not the owner of that playercharacter.

#

if they try to send a playerinput rpc threw another playercharacter it wont work.

#

but picture this, you make an RPC with say, equip sword or something.. you need to make sure the server has logic to check to see if the sword exists.

#

because anyone can tell the server anything threw the copy of the playercharacter they own threw the server rpcs you make.

raven trench Feb 14, 2020, 4:51 PM

#

ok got it I think mate. Thanks again for explaining it all! Very grateful!

update on my situation: I compiled a Windows server and it's the exact same thing - but it doesn't say anything about the steam client. it just doesn't show up in the server list & i'm not able to connect to it...

your app id correct?

marble depot Feb 14, 2020, 5:46 PM

turn on verbose logging

#

?

marble depot Feb 14, 2020, 5:47 PM

#

i believe it's on - also it's a development build

#

i'm on 4.19 btw

meager spade Feb 14, 2020, 5:47 PM

#

wont be on by default

#

unless you explicitly turn on verbose

marble depot Feb 14, 2020, 5:47 PM

#

how do i turn it on?

#

is it one of those bools like "bVerboseLogging"?

meager spade Feb 14, 2020, 5:49 PM

#

no

#

LogKaosWeapon=Verbose
LogKaos=Verbose
LogKaosInventory=Verbose```

#

like that in the Engine.ini file

#

and choose like LogSteam or w/e the logs are

#

LogNet, etc

marble depot Feb 14, 2020, 6:03 PM

#

did that, compiled a server and looking through the log and to it, everything's working properly

#

the only bad thing that I see is:

[2020.02.14-18.00.30:007][ 42]LogNet: World NetDriver shutdown SteamNetDriver_0 [GameNetDriver]
[2020.02.14-18.00.30:007][ 42]LogNet: DestroyNamedNetDriver SteamNetDriver_0 [GameNetDriver]
[2020.02.14-18.00.30:007][ 42]LogExit: GameNetDriver SteamNetDriver_0 shut down

#

it's after it finishes loading everything and is listening

viral kite Feb 14, 2020, 6:32 PM

#

I have a very noobish question, I added multiplayer support to a test project, it works if I try it on my two pcs (lan is unchecked) I can create the session and join with the other pc... but if I give the game to a friend it is not working.

viscid escarp Feb 14, 2020, 6:36 PM

#

@viral kite so you are working with a dedicated server?

#

because if lan is unchecked is should be a dedicated server

viral kite Feb 14, 2020, 6:39 PM

#

ne i have no dedicated server -.-

viscid escarp Feb 14, 2020, 6:40 PM

#

so you have to check LAN and connect with something like hamashi

#

btw someone know if i should build my game in VS with "Development Server" everytime before package the dedicated server?

viral kite Feb 14, 2020, 6:42 PM

#

a dedicated server is not possible with blueprints?

marble depot Feb 14, 2020, 6:43 PM

#

no, you have to compile the engine from source

viscid escarp Feb 14, 2020, 6:44 PM

#

yeah, but you dont have to know c++
