The PlayerState one should have worked already though

#

Another is:

Array of PlayerControllers in GameMode.
OnPostLogin: Add NewPlayer to Array
OnLogout: Remove LeavingPlayer from Array
Also OnPostLogin: Loop over the array (before adding the NewPlayer) and call a CLIENT RPC on the PlayerController

rare cloud Sep 2, 2017, 6:43 PM

#

there is an array of playerstate on GameState

lilac egret Sep 2, 2017, 6:47 PM

#

yes, but one player is the server, so I have to multicast a function right?

#

to reach the second player

thin stratus Sep 2, 2017, 6:49 PM

#

I have the feeling you simply ignore suggestions

#

Have you tried what i wrote?

lilac egret Sep 2, 2017, 7:20 PM

#

by client rpc you mean a run on owning client function on the player controller?

wary willow Sep 2, 2017, 7:47 PM

#

@thin stratus you should create a new MP MP asset. What MPx2. Take all the common things people need/ask and make something very generic. Something like Content Examples. But just purely geared towards MP. I would say there's a market for it. $$$$$

#

A crapton of Multiplayer Content Examples. Charge $99. Win.

hey guys, I'm trying to replicate my bOrient RotationToMovement property for my character movement, but even though it's set in a server function, and even though the movement component is set to replicate, it doesn't seem to be happening. Any ideas what I might have missed?

ruby epoch Sep 2, 2017, 8:23 PM

#

best way to make hp and name over head?

undone crane Sep 2, 2017, 8:31 PM

#

@ruby epoch If I wanted it to appear like a thing in the world, I would attach a widget to the character's head and update the direction in points on each client.

ruby epoch Sep 2, 2017, 8:34 PM

#

that the simplest way

#

but maybe other ideas?

brittle sinew Sep 2, 2017, 8:35 PM

#

What's wrong with that approach?

ruby epoch Sep 2, 2017, 8:37 PM

#

for each update I must collect all actors of class and update rotation, I dont like this way

brittle sinew Sep 2, 2017, 8:38 PM

#

@undone crane that's not a replicated property (even though it's on a replicated component), so if you want to change it on all clients you'll need to multicast it

ruby epoch Sep 2, 2017, 8:38 PM

#

it should change on each client

#

not multicast

brittle sinew Sep 2, 2017, 8:38 PM

#

@ruby epoch what? Just have each player update their own widget, or just put the widget into screen space

ruby epoch Sep 2, 2017, 8:38 PM

#

I must update rotation on each player

#

for all other players

#

for correct rotation

brittle sinew Sep 2, 2017, 8:39 PM

#

I'm not really sure what you're thinking you're trying to do here

ruby epoch Sep 2, 2017, 8:39 PM

#

em...

#

widget have different rotation for 3 players

#

so I have rotate it locally

brittle sinew Sep 2, 2017, 8:40 PM

#

Yeah.

#

Is that a bad thing?

undone crane Sep 2, 2017, 8:40 PM

#

@brittle sinew Weird that I can't find that sort of information here: https://docs.unrealengine.com/latest/INT/API/Runtime/Engine/GameFramework/UCharacterMovementComponent/index.html

ruby epoch Sep 2, 2017, 8:40 PM

#

so each tick I have to collect all actors of player class and rotate their widgets locally

#

I dont like that way

brittle sinew Sep 2, 2017, 8:41 PM

#

Why would you need to get all of the player class?

#

Why not have each pawn do it internally?

ruby epoch Sep 2, 2017, 8:41 PM

#

seems you dont understand what I mean

#

also, I can use players from game state

brittle sinew Sep 2, 2017, 8:42 PM

#

No, I don't think you understand how encapsulation would work here 😃

#

You simply have each pawn update their widget on the client

#

Pawns tick on clients. The widget rotations don't have to be replicated

ruby epoch Sep 2, 2017, 8:42 PM

#

....

brittle sinew Sep 2, 2017, 8:44 PM

#

You could get all actors of class and set it each tick.

#

That would work.

#

But I agree, that's not a great way to do it.

#

If you have each pawn handle their widget within the class, that's much better

#

@undone crane yeah, replication status doesn't show on the doc pages :/

undone crane Sep 2, 2017, 8:47 PM

#

@brittle sinew That's annoying...turns it into trial and error.

brittle sinew Sep 2, 2017, 8:47 PM

#

Well, not really

#

I just look at the headers for that

undone crane Sep 2, 2017, 8:47 PM

#

ah

lilac egret Sep 2, 2017, 8:55 PM

#

you were wrong

#

I had to call a function on the player state to send to game state, to traverse through the player array then call a Run on owning client function on the player's player state to notify of the newly joined ones

#

to allert

#

cedric

rare cloud Sep 2, 2017, 8:58 PM

#

@lilac egret, why ?

#

I mean GameMode::PostLogin, and you get PlayerArray from AGameState

#

and call the RPC

#

on each PlayerController

lilac egret Sep 2, 2017, 8:59 PM

#

what do you mean by RPC

#

be more specific

rare cloud Sep 2, 2017, 9:02 PM

#

void NotifyNewPlayerOnClient();```

lilac egret Sep 2, 2017, 9:02 PM

#

you mean a Run on owning client, multicast?

#

i dont understand just by "RPC" sorry

#

is that function the blueprint equivalent of Run On Owning Client?

rare cloud Sep 2, 2017, 9:07 PM

#

@lilac egret, declare this on your AMyGameMode::PostLogin :

AGameState* GameState = GetWorld()->GetGameState();
    if (GameState != nullptr)
    {
        for (APlayerState* PlayerState : GameState->PlayerArray)
        {
            AMyPlayerController* MyController = Cast<AMyPlayerController>(PlayerState->GetOwner());
            if (MyController != nullptr)
            {
                MyController->NotifyNewPlayerOnClient();
            }
        }
    }

#

after go to your player controller

#

declare this UFUNCTION( Client ) void NotifyNewPlayerOnClient();

#

on your header

#

and this on your cpp

void AMyPlayerController::NotifyNewPlayerOnClient_Implementation()
{
    //Do what you want
}

lilac egret Sep 2, 2017, 9:11 PM

#

thanks man

#

this "UFUNCTION( Client )" is the same as Run on owning client on blueprints?

rare cloud Sep 2, 2017, 9:13 PM

#

yeah

lilac egret Sep 2, 2017, 9:15 PM

#

there is one game instance created for each player and there is only one game state?

rare cloud Sep 2, 2017, 9:16 PM

#

there is an object called UGameInstance, which exist for all client but it's not replicated

#

it's the instance of the game

#

there is only one game state

twin juniper Sep 2, 2017, 11:54 PM

#

how could i make a menu appear ( for character creation ) before you spawn into the map? And how would I save these things in a multiplayer scenario? As well as replicate changes of the character (hair color, size, etc)

#

Not sure how to do this

#

lol

stark dome Sep 3, 2017, 12:38 AM

#

Well first off do you know how to add a widget to the screen

#

Go step by step don't just jump into everything at once

sweet spire Sep 3, 2017, 12:48 AM

#

Yes u can, premake char offline after logged in

#

Then onfe char is done and u click accept

#

Json request to database

#

And if it is successful it send msg back saying yes oe no

#

Or

twin juniper Sep 3, 2017, 1:15 AM

#

@stark dome of couhrse xD

#

@sweet spire not using postgres, im using sqlite like conan exiles uses

lilac egret Sep 3, 2017, 1:15 AM

#

to replicate a Play anim montage

twin juniper Sep 3, 2017, 1:15 AM

#

noit ostgres or any type of db like that

lilac egret Sep 3, 2017, 1:16 AM

#

i make a run on server event that calls a multicast event that plays the anim montage?

stark dome Sep 3, 2017, 1:17 AM

#

So you can spawn a custom pawn responsible for showing the UI for character creation

#

Just make that the default pawn instead of your actual pawn

hasty adder Sep 3, 2017, 1:18 AM

#

/dance

lilac egret Sep 3, 2017, 1:19 AM

#

how

#

if im at a run on owning client event, how do I switch to a normal event

#

?

hasty adder Sep 3, 2017, 1:26 AM

#

Hm from what I read I think there is a miss of understanding clients have there own copy of the world and actors. Including the logic being run on them locally. Just not all the values the other persons version might have. Meaning if you have a widget running a tick it's tick is running its own version local to each client with what it knows. So when you have a widget on a player in world or on screen tm your clients version of the logic it knows is running. Hence if it was just getting playerstate -> name with no logic saying get the owners player state your name would appear over everyone's head or your health etc. updating values to the server to then multicast are to update other people version of the world to match yours

#

What's your montage show happening? @lilac egret

lilac egret Sep 3, 2017, 1:28 AM

#

What

#

Its a Play anim montage

#

I want to replicate it

hasty adder Sep 3, 2017, 1:29 AM

#

I'm trying to get context to give an example. Is it a reload. Draw weapon. Dance? 😃

#

One way if it's just run an animation is key press E for example. E-> run on server ---> multicast. --> play montage

#

But your character is subject to the latency before you see it since tm your waiting for the server to feed back to you to run your montage. Where you can instead E-> switch authority --> authority --> play montage // remote run on server->multicast-> if controlled pawn != self play montage

lilac egret Sep 3, 2017, 1:34 AM

#

Its an attack animation

#

Whats the difference of run on server -> multicast to switch has authority?

#

When do i use switch has authority

hasty adder Sep 3, 2017, 1:35 AM

#

Authority is about ownership which is confusing but again in context of each persons own version of the world

#

Since in an even by key press your doing something local you are authority but your saying remote versions would run this. Since you can't directly tell them what your going to have server run it in a multicast event to tell everyone else to run the logic. It's confusing which I could explain it better

#

Wish*

#

It's not a replication though it might as well be a bool sorta like if locally controlled but it has more to it then that because it could be server as the authority who isn't locally controlled

#

Like I would play with print statement to get what's happening.. Say p = print hello

#

Use a switch authority and have hello on authority and hi on remote

#

Just know it's not replicating the print if it's hard coded. It's just running the same routine in the context of who is auth and who is remote

#

I've said to much 😷

stark dome Sep 3, 2017, 2:07 AM

#

If it's an attack animation for an event triggered by the client you should most likely play it based on client input

#

If it's for an AI or another player you should either play it after an rpc or when the state is replicated

sick stag Sep 3, 2017, 5:29 AM

#

I am having an issue replicating an anim montage to all clients. It does not matter what combination i use for replication it just does not want to cooperate. I have successfully replicated every anim state pose blend etc. except this montage lol. (BP) AnimBP Event Graph Custom event for Run on server and run on client. Character BP Custom event (Multicast - is Server True - Client, False - Server and Client. Client and Server can see the animations owner, All clients can see server animation. Clients cannot see other client animation.(Single Montage)

thin stratus Sep 3, 2017, 10:10 AM

#

@sick stag You have rpcs in your animBP?

sweet spire Sep 3, 2017, 11:06 AM

#

Cedric question for you

#

do u actually need to replicate montages? or has everyone gone potato, i see people talking about animation replication all the time, and all i think is, why arent u driving it from important game states??

thin stratus Sep 3, 2017, 11:09 AM

#

So you have to split that into 2 areas. Replicating Montages and replicating the AnimBP

#

AnimBP usually works like this: You set it up with Variables you create inside of the AnimBP (so local to the AnimBP), and make sure the whole Animation State Machine works with them.
Then you get the Pawn in the EventGraph and get all the variables from it a to fill the Local ones that drive the Anims

sweet spire Sep 3, 2017, 11:10 AM

#

yeah thats what i do

thin stratus Sep 3, 2017, 11:10 AM

#

The Pawns variables, that you get, should (if not already) be replicated

#

So everyone has the correct values

sweet spire Sep 3, 2017, 11:10 AM

#

I drive my animation bp's by important game states

#

same with VFX and stuff

thin stratus Sep 3, 2017, 11:11 AM

#

And VFX, Montages etc, are usually driven by either an OnRep variable or a Multicast

sweet spire Sep 3, 2017, 11:11 AM

#

just been hearing alot of montage rep issues from people and was curious

#

i drive most of my stuff by using helper rep actors that recieve broadcast tags and stuff

thin stratus Sep 3, 2017, 11:11 AM

#

Only special case you ahve is if you have, for example, effects that can be driven by things the clinet already knows, you do it that way

#

That includes, step sounds, cause the anim is already playing on the character

#

Shooting FX (muzzle) etc

sweet spire Sep 3, 2017, 11:12 AM

#

yeah i drive everything from states of things actually happening

#

very rarely can i justify replicating just vfx

thin stratus Sep 3, 2017, 11:12 AM

#

People that have trouble with AnimBP replication are simply doing things wrong OR (not to blame them for everything) having an engine bug :P

sweet spire Sep 3, 2017, 11:13 AM

#

haha true

#

i find alot of people struggle to wrap there head around the idea of every replicated pawn has its own state on every client

#

like pawn 7's IsCrouching bool has nothing to do with pawn 5's

#

if u get me

thin stratus Sep 3, 2017, 11:14 AM

#

Yes, they see one Character is one

sweet spire Sep 3, 2017, 11:15 AM

#

Swear to god i need to write a guide about it, with breakdown on white board

thin stratus Sep 3, 2017, 11:15 AM

#

And not as a construct of one local driven, one server driven and rest client puppets

sweet spire Sep 3, 2017, 11:15 AM

#

iv explained it so many times to peope haha

#

but then when they see the light, feels good man

thin stratus Sep 3, 2017, 11:15 AM

#

I might just add it to my compendium

sweet spire Sep 3, 2017, 11:15 AM

#

that would be a 10/10 idea

#

buff it up with that & some more core examples on things would prob help alot of people

#

I think we see alot of questions about driving animation bp's & displaying things like health for the correct pawn

fossil spoke Sep 3, 2017, 11:35 AM

#

@thin stratus Making that exceptionally obvious would help alot of people. I find myself explaining it far to often.

#

Especially when its so fundamental to understand.

jolly siren Sep 3, 2017, 1:31 PM

#

Does anyone know if it is possible to write a secure radar? Characters exist on server and all clients. So I don't really see how you could stop someone from hacking the radar and plotting points for every character regardless of how far away they are, invisible state, etc.

brittle sinew Sep 3, 2017, 1:33 PM

#

If you're sending the information to the clients, you have to assume they can use it

#

I know CS:GO implemented something where they only get sent info about other characters if the server decides they're about to see them or something to that effect

#

So, when they're on opposite sides of the map, the client literally doesn't know about the other character

thin stratus Sep 3, 2017, 1:34 PM

#

You stop replicating the Characters if they are not in sight

brittle sinew Sep 3, 2017, 1:34 PM

#

I'm sure that's not super easy to implement well, though

thin stratus Sep 3, 2017, 1:34 PM

#

We had that a couple of days ago

jolly siren Sep 3, 2017, 1:34 PM

#

Ahh actually I remember someone pasting code from shootergame about that

thin stratus Sep 3, 2017, 1:34 PM

#

I think it's somewhere in the UT code

#

Or Shootergame

#

yeah

jolly siren Sep 3, 2017, 1:34 PM

#

may have been UT, let me check

#

that makes sense tho

inner iris Sep 3, 2017, 1:35 PM

#

It's in Shootergame for sure

#

But how does the server then predict when a player would see an enemy?

#

For example with 200ms lag both ways

brittle sinew Sep 3, 2017, 1:35 PM

#

Yeah...that's the hard part.

inner iris Sep 3, 2017, 1:35 PM

#

Could cause some dodgey situations where the enemy just appears on the client?

brittle sinew Sep 3, 2017, 1:35 PM

#

I remember when it first came out, it was a mess for anyone above 100ms

#

I think they had to end up loosening the calculations on it, else people were just popping into existence around corners

#

It's a balance for sure, you can't hide everything from the client and still have the game work super well in networked settings

jolly siren Sep 3, 2017, 1:39 PM

#

ahh right it's AShooterCharacter::IsReplicationPausedForConnection

inner iris Sep 3, 2017, 1:40 PM

#

Have an ultranoob question- since event begin play and event tick seems to run on both server and client, but a regular custom event just runs on a client, or an RPC has to be sent from client to server- is the server simply running the same code as the client, but replicating any changing values back down to the client, as opposed to the client sending RPC's on tick?

jolly siren Sep 3, 2017, 1:40 PM

#

Thanks guys, this was helpful; appreciate it.

#

a regular custom event just runs on client? That's not true, it just runs wherever you call it at

#

it's just a function

inner iris Sep 3, 2017, 1:48 PM

#

Well for example, on event begin play, the server and client both run whatever is connected to it

#

But I have a regular custom event hooked up to a keypress, it'll only run on the client unless I specify it should run on server

#

So do I assume that the tick and begin play events will run the logic both on client and server consistently?

jolly siren Sep 3, 2017, 1:49 PM

#

right, because only clients cause input

inner iris Sep 3, 2017, 1:49 PM

#

Ah right

#

So server just doesn't know about it

jolly siren Sep 3, 2017, 1:49 PM

#

right

inner iris Sep 3, 2017, 1:49 PM

#

But tick and begin play happen not because of input

#

Gotcha

#

Ok thanks a lot

#

Stupid question but was trying to figure out why and where things are called

not stupid, takes a while to get it all

Please, I am dying from this...
So, I setup my dedicated server
And I have couple of mods... The ones that have small map t play on work just fine
the problem comes when I try to run a mode with map 20x20km. My test server has only 1 gb of ram and it shows this... [2017.09.03-11.59.07:388][ 2]LogOnline:Warning: Async task 'FOnlineAsyncTaskSteamCreateServer bWasSuccessful: 0' failed in 17.200534 seconds
It works perfectly fine on my personal PC which has 16gb of ram
But the people that are testing my game to see how powerful server I need get this message as well
and they have 128gb of ram
so I googled a little and I found that AsyncTaskTimeout=180 line in the DefaultEngine.ini should help. With this added, I get on my test server:
Steam connection failure
and on the test servers which are in the london data center I get the same message as previously

#

why is a function on the game instance working if called from a widget, but doesnt work if called from anywhere else?

rare cloud Sep 3, 2017, 5:19 PM

#

@lilac egret, because you surely call it from server

#

widget is client side only

lilac egret Sep 3, 2017, 5:20 PM

#

so I call on owning client?/

rare cloud Sep 3, 2017, 5:21 PM

#

use a switch has authority

#

if you use BP

#

with cpp you can filter using the Role variable of the Actor

#

or with Actor->HasAuthority()

lilac egret Sep 3, 2017, 5:22 PM

#

and after the switch has authority?

#

if it's remote, i call a run on server event?

#

I tried all ways, but it only works when called from widget

inner iris Sep 3, 2017, 10:05 PM

#

Any ideas why this calls somewhat inconsistently on the client? 9 times out of 10 the first shot runs only on server, but clients don't see the FX. Then after the second or third shot, it runs on all clients as expected. Also when swapping through editor clients(different windows), the first shot usually doesn't work like before

#

📎 Screenshot_2017-09-03_23.02.51.jpg

#

So server will call the hello print string always but clients only after the first shot or two- even after running around for a few seconds after selecting a new client window, it happens

So spawning a replicated actor on the server and destroying it on the same frame means the actor will never spawn on the client

#

But if you fire a reliable RPC as it spawns then the client does in fact get it... the first time after the begin play, but any times the actor is spawned after that the RPC hits the client before begin play... seems pretty weird

#

I guess actor spawn messages aren't reliable?

twin juniper Sep 4, 2017, 3:55 PM

#

So I found out that the error shows on a machine with less than 3 ghz processor.. So the issue should be in timeout. How can I increase the timeout of asyncTask please?

tacit hazel Sep 4, 2017, 5:48 PM

#

ok so I have a replicated static mesh, but it only apears on the server

#

do static mesh's not replicate?

#

someone help pliz

modern dome Sep 4, 2017, 6:26 PM

#

@tacit hazel what do you mean with "Static Mesh" ? A StaticMesh Component or a StaticMesh Actor?

#

Or do you have a custom BP which uses a StaticMeshComponent?

tacit hazel Sep 4, 2017, 6:40 PM

#

static meson component

#

StaticMeshComponent

#

I have it set to Replciated

#

but it never apears on clients screens, only on the server

#

@modern dome

modern dome Sep 4, 2017, 7:28 PM

#

Make sure the actor itself is set to replicate

tacit hazel Sep 4, 2017, 7:32 PM

#

it is

maiden atlas Sep 4, 2017, 9:54 PM

#

I haven't tried any online subsystems besides Steam. Do they all essentially work the same in engine?

#

@tacit hazel Make sure that the static mesh doesn't exist at all on the client. It might exit but not have the position replicated correctly.

#

With the null system you can't find sessions, but you can still host a listen server and join via ip address command, right?

thin stratus Sep 4, 2017, 10:12 PM

#

You can find Sessions, but only LAN

#

And yes, for Internet you can join via IP

#

Make sure ports on the host are open

maiden atlas Sep 4, 2017, 10:24 PM

#

I don't know anyone who was ever able to make port forwarding work

brittle sinew Sep 4, 2017, 10:25 PM

#

🤔

#

It's pretty simple, I've never had any issues with it

#

Takes ~30 seconds in my router control panel

#

There are websites that show you exactly how to do it on certain popular routers/brands

#

ipconfig in cmd (ifconfig on Linux/Mac probably), get the local IP, then forward the port (I always just do TCP+UDP) to that IP

wide valley Sep 4, 2017, 10:33 PM

#

can anyone suggest tutorials that explain how to handle gamestate states ( Kills, Deaths, etc ) using blueprints in a multiplayer game?

thin stratus Sep 4, 2017, 10:34 PM

#

That's pretty easy

#

Create a Custom PlayerState and add these variables to it

#

Mark the as Replicated

#

That's it

#

You can access the PlayerState via:

PlayerCharacter if possessed
PlayerController (local and server, not other clients)
GameState PlayerArray

#

@maiden atlas Open Router, go to Forward Settings, enter Port Range, select UDP or TCP, select your local IP Address of your PC

#

That's it

#

Only thing that might still do bad stuff is the windows firewall

maiden atlas Sep 4, 2017, 10:36 PM

#

Yeah, I tried that before. Never worked.

brittle sinew Sep 4, 2017, 10:41 PM

#

Sites like http://canyouseeme.org can help debug that, finding out whether it's a problem with the router or not

#

I agree with Cedric, the Windows firewall might be the culprit there, as if you're forwarding the port in the router I find it unlikely it just wouldn't forward it

#

(if you get "connection refused" on that site, that's actually a good thing. That means you're actually getting through the router and the internal device is refusing it)

thin stratus Sep 4, 2017, 10:54 PM

#

I often get "not visible" although I'm visible

#

Check 7777, not visible but I can easily host

#

:P

brittle sinew Sep 4, 2017, 10:54 PM

#

Maybe that site checks TCP when UE4 uses UDP? Dunno

#

I always just forward both

#

Probably not the safest, but meh

#

Also, it only shows visible if there's a service currently running on that port, if you didn't know already

tacit hazel Sep 4, 2017, 11:41 PM

#

how would I make sure it doesnt exist on the client?

#

Im 90% sure ity doesnt because I cant find it at the spawn point, or underground or way high or anything

maiden atlas Sep 4, 2017, 11:43 PM

#

Client side debug messages checking if the reference is null?

tacit hazel Sep 4, 2017, 11:44 PM

#

ok one sec

tacit hazel Sep 5, 2017, 1:28 AM

#

ok I can confirm it does not exist for clients

#

@maiden atlas

maiden atlas Sep 5, 2017, 1:30 AM

#

Ok.. How is it being created exactly? Part of an actor that is placed, part of an actor that is spawned, created at runtime?

tacit hazel Sep 5, 2017, 1:30 AM

#

part of an actor that is spawned via a playerstart

#

it is set during runtime when the player equips a gun

maiden atlas Sep 5, 2017, 1:31 AM

#

spawned on server side?

tacit hazel Sep 5, 2017, 1:31 AM

#

correct

maiden atlas Sep 5, 2017, 1:31 AM

#

Actor exists, but its static mesh component does not?

tacit hazel Sep 5, 2017, 1:32 AM

#

correct

#

the players mesh exists, but not the guns

#

I don't knwo why

maiden atlas Sep 5, 2017, 1:34 AM

#

Well, Its really unusual for only parts of an actor to be replicated in its spawn

tacit hazel Sep 5, 2017, 1:34 AM

#

https://hastebin.com/ubolavavub.php

maiden atlas Sep 5, 2017, 1:35 AM

#

It wouldn't so weird if just the static mesh was null, but for the whole static mesh component to be null is really odd

tacit hazel Sep 5, 2017, 1:36 AM

#

oh I checked that static mesh let me make sure the whole component isnt null

#

the component exists

#

on clients

#

but no the static mesh itself

#

@maiden atlas

maiden atlas Sep 5, 2017, 1:38 AM

#

"initialize gun function" where is this exactly?

tacit hazel Sep 5, 2017, 1:39 AM

#

in the character

maiden atlas Sep 5, 2017, 1:41 AM

#

Where in the character? What function is it called from?

tacit hazel Sep 5, 2017, 1:41 AM

#

https://hastebin.com/tadisupezo.php

maiden atlas Sep 5, 2017, 1:41 AM

#

"UFUNCTION(Reliable, Server, WithValidation)
void InitializeGun();//spawns the gun "

#

Its null on the client because the function only runs on the server

tacit hazel Sep 5, 2017, 1:42 AM

#

doesn't Replicated relicate it though?

maiden atlas Sep 5, 2017, 1:43 AM

#

no?

#

What do you mean by that?

tacit hazel Sep 5, 2017, 1:43 AM

#

well since SM_Gun is set to be (Replicated) shouldn't it also apear on the cleints?

#

I am new to Unreal's Networking so I could be very wrong

maiden atlas Sep 5, 2017, 1:44 AM

#

SM_Gun is the component, not the mesh asset, and it should not need to be replicated

tacit hazel Sep 5, 2017, 1:44 AM

#

so what is Replicated then exactly?

maiden atlas Sep 5, 2017, 1:45 AM

#

For replicating variables from server to clients

tacit hazel Sep 5, 2017, 1:45 AM

#

soooooooo......... does that not include static mesh's? I assume

maiden atlas Sep 5, 2017, 1:45 AM

#

UStaticMeshComponent* SM_Gun

#

That is a pointer to a UStaticMeshComponent

#

The only thing you are replicating by doing that, is that specific pointer

tacit hazel Sep 5, 2017, 1:46 AM

#

ooooooooooooohhhhhhhhhhhhhhhhhhhhhh which means absolutly nothing for the client then because pointers arent shareable

#

right?

maiden atlas Sep 5, 2017, 1:47 AM

#

What do you mean by "not shareable"?

tacit hazel Sep 5, 2017, 1:47 AM

#

a pointer on one machine could point to something completly different on another

#

since its a memory address

maiden atlas Sep 5, 2017, 1:47 AM

#

Its pointless because you already set the pointer in the constructor and there is no reason for it to have changed

tacit hazel Sep 5, 2017, 1:47 AM

#

ok I see

maiden atlas Sep 5, 2017, 1:48 AM

#

A replicated pointer will be converted to point to the "equivalent" object, if it exists

tacit hazel Sep 5, 2017, 1:49 AM

#

thank you very much @maiden atlas

maiden atlas Sep 5, 2017, 1:50 AM

#

you're welcome

tacit hazel Sep 5, 2017, 2:26 AM

#

I set the function to NetMutlicast but its still only showing up for the server only unfortunatly

#

ok got it working

#

                TEXT("?listen"),
                TEXT("?bIsLanMatch=1"));```
the create string

#

should mention this is a Steam lobby thing

wide valley Sep 5, 2017, 3:53 AM

#

anyone have an example or know of a tutorial that shows the use of playerstats with playercontrollers in a multiplayer setting, keeping track of kills deather or whatever you want per player. I am still not getting my head around this whole flow. Something isn't replicating properly. I just want to make sure I am architecting this the right way from the get go here. ( sorry if its a noob question ive only been using unreal for a couple weeks ).

weak pasture Sep 5, 2017, 3:56 AM

#

are you using a PlayerState?

#

player controllers arent a good thing to hold stats because other clients don't ever receive other players controllers, only the server sees all

wide valley Sep 5, 2017, 3:56 AM

#

i am trying to use playerstate yes

#

just not sure the right way

weak pasture Sep 5, 2017, 3:57 AM

#

do you have a GetLifetimeReplicatedProps?

#

with UPROPERTY(Replicated) on the variables you want to replicate

#

https://wiki.unrealengine.com/Replication

Replication

#

if you haven't taken a look, thats what kickstarted me on replication

wide valley Sep 5, 2017, 4:05 AM

#

I was actually working in blueprints =/

#

I will read through this document though thank you for sharing it

#

If I was going to go the whole c++ route, Craig, what tutorial should I start with. To get where I am now I went through the whole blueprint multiplayer youtube series and it was really nice to see something happening at the end of it, however it didn't give me a good feeling of how everything worked.

weak pasture Sep 5, 2017, 4:14 AM

#

yeah im not too sure about blueprints we used c++ from the word go on Sky Noon. i know theres some pretty hefty limitations with blueprint networking, our starting point was to download ShooterGame and look at how that did its networking, youll want to familiarise yourself with replication (that wiki page above) and RPCs, https://docs.unrealengine.com/latest/INT/Gameplay/Networking/Actors/RPCs/

RPCs

Designating function replication across the network

#

if you aren't confident in c++ disregard what i said, its like jumping in the deep end with a concrete jacket on

#

theres probably some kind of decent blueprint multiplayer tutorials out there, just bear in mind the limitations youll hit (for example, at least in earlier versions of UE4, there was no seamless travel in BP)

wide valley Sep 5, 2017, 4:18 AM

#

yeah i don't like limitations but I don't know c++ ( i know plenty of other languages )

#

yeah it feels a bit scary

weak pasture Sep 5, 2017, 4:20 AM

#

sweet as, best work out the networking basics in BP if you can, eventually C++ will be a gold mine, and id highly recommend learning it eventually, but as always with unreal engine, baby steps is great

maiden atlas Sep 5, 2017, 4:20 AM

#

That tutorial series was full of misinformation

#

Aside from just being a bad tutorial in general

#

The steam multiplayer series was rife with putting replicated functions and variables in classes that only exist on the server

#

It was also bad for "I'm not going to explain what this does or why I put it here, just copy these nodes"

weak pasture Sep 5, 2017, 4:24 AM

#

which ones that, the replication one?

wide valley Sep 5, 2017, 4:26 AM

#

Where do you think I should start BlackFang, i certainly don't want to learn dirty methods 😃

weak pasture Sep 5, 2017, 4:28 AM

maiden atlas Sep 5, 2017, 5:04 AM

#

There was a thread about what that series got wrong that might be good to read through, if you can find it on the new forum

#

I tried to learn from it initially and honestly think it would have been better to completely start from scratch and just do trial and error on my own

talking about this tutorial? https://docs.unrealengine.com/latest/INT/Videos/PLZlv_N0_O1gYqSlbGQVKsRg6fpxWndZqZ/abmzWUWxy1U/

01 - Project Overview

In this video we take a look at the finished project and step through each of the features that will be covered in this series. We show our functional Main Menu and its options, a lobby where players can chat with one another and select their characters for the game, some server options such as changing the map or match time as well as the ability to kick players from the lobby, all of this working with Steam integration. So if you are wondering how to build a networked game through Blueprints with Steam, this is the series for you!

#

I sorta found the same thing with that.. the dude seemed to just replicate random things that didn't really make sense

#

as if the guy had just gone through setting replicate on stuff until it worked

#

Happen to have the link to that thread Blackfang?

rough iron Sep 5, 2017, 7:08 AM

#

@weak pasture you already said it, offline LAN and steam do not work together. You can not use SteamWorks and online sessions if you are offline xD. Right now I do not know what the OSS does internally but it should not call any online or sessions things. If that's not the case you (the caller) is responsible.

#

you might want to use OnlineSubsystemNull for the LAN case

weak pasture Sep 5, 2017, 7:18 AM

#

hey moss, cheers, should have posted in here that i fixed it, using bIsLANMatch and LAN is true falls back to Null OSS i believe, was using default sockets and stuff anyway, i took in the wrong bool in the session settings creation which was why it wasnt working, which was stopping it from falling back to Null OSS. Cheers!

why is onRep unreliable compared to multicast? i ran a test and about 10-15% of the time onRep does not trigger vs a reliable multicast always triggering 100% of the time... ???

rare cloud Sep 5, 2017, 3:03 PM

#

@twin juniper, OnRep use standard replication, which is slower than RPC but better in term of performance

inner iris Sep 5, 2017, 5:11 PM

#

@twin juniper having a similar inconsistencies with RepNotify- seems to only consistently run on the server and not on the client always and I can't find a clear reason why.

maiden atlas Sep 5, 2017, 5:21 PM

#

The whole point of those is that they get dropped when there isn't enough bandwidth

inner iris Sep 5, 2017, 5:29 PM

#

Just tested on a blank project- seems I had the server overriding the bool depending on a weapon's fire rate- @twin juniper do you have the bool being set back to false again at any point after it being called?

Did you define the net driver in the .ini?

wintry cove Sep 5, 2017, 8:54 PM

#

yeah

#

plugins are enabled

#

config is set to use steam, also fails on null though

fleet sluice Sep 5, 2017, 8:55 PM

#

NetDrivers are only created when you start a dedicated server, open a map with "?listen" or simply call GetWorld()->StartListen() (or something similar; not sure if it was GetWorld())

maiden atlas Sep 5, 2017, 8:55 PM

#

Only on dedicated servers?

#

So not on listen servers?

fleet sluice Sep 5, 2017, 8:56 PM

#

Well opening a map with "?listen" is a listen server

#

Same for StartListen()

maiden atlas Sep 5, 2017, 8:56 PM

#

"NetDrivers are only created when you start a dedicated server"

fleet sluice Sep 5, 2017, 8:56 PM

#

There's a comma in my sentence though

#

It's an enumeration

maiden atlas Sep 5, 2017, 8:56 PM

#

So no net drivers on listen servers then?

fleet sluice Sep 5, 2017, 8:57 PM

#

Let me rephrase: NetDrivers are created in 3 situations:

When you start a dedicated server.
When you open a map with "?listen".
When you call GetWorld()->StartListen() (or something similar; not sure if it was GetWorld())

#

So yes, listen servers too

You can't really control when variables replicate; if you need that variable inside of another function, send it as a parameter.

detect the event that triggers the sound on the client

twin juniper Sep 6, 2017, 2:54 AM

@minor wedge so if the sound is triggered by overlap on another actor

#

is the other actor remote?

#

or authority

minor wedge Sep 6, 2017, 2:55 AM

#

You can trigger overlaps on both

twin juniper Sep 6, 2017, 2:55 AM

#

but

#

i only want it

#

on the client

#

lol

#

so would it be remote

#

or authority

minor wedge Sep 6, 2017, 2:56 AM

#

So see if it's local

#

local player controller

#

A client can be remote and a client can be authority, you want to see if it's locally controlled to determine if there's a player on the end you're checkin.

twin juniper Sep 6, 2017, 3:00 AM

#

@minor wedge i want to see

#

ok

#

nvm i got this :p

twin juniper Sep 6, 2017, 10:34 AM

#

@twin juniper you can get just the owning client if you have access to pawn with if(Pawn && Pawn->IsLocallyControlled() { }

#

playercontroller access too the same way

inner iris Sep 6, 2017, 11:12 AM

#

IsLocallyControlled applies to each separate window right- for example if you had 3 PIE windows, only the active window that is being played and calls the code will return true for IsLocallyControlled, correct?

#

Since in my mind, the other two windows are locally controlled in a literal sense, but I guess it more means: is being controlled by this pawns controller, therefore its local controller?

twin juniper Sep 6, 2017, 11:36 AM

#

@eoinobroin#6833 that would make sense

inner iris Sep 6, 2017, 12:31 PM

#

#

Well after a bit more looking around (on mobile atm) it would seem like it should return true on all PIE windows based on this:

#

However maybe checking "run dedicated server" treats all other PIE windows as separate clients and therefore network connections and not local connections, making is locally controlled only return true for the active window (client).

wondeing if anyone can help? I am hosting a session via steam using advanced sessions and always get this warning about a player state on my dedicated server. I know its not valid as its a dedicated server, but is there any way around making it look for one?

Thanks

#

How come that works when there is no replication, but not when it is being replicated?

twin juniper Sep 6, 2017, 1:51 PM

#

@lament kettle check if the equipped actor is valid

#

its probably not set

#

to anything

lament kettle Sep 6, 2017, 1:52 PM

#

hmm

#

interesting

#

ill look into that

worthy wasp Sep 6, 2017, 2:08 PM

#

hey all - is there any docs out there (i've looked - cant find much but a bunch of unanswered stuff on answerhub) for NON-LOCKING loading screens ..... I think it has to do with joining a session - or server travel that is NON-seamless (Client drops & reconnects - or initial connect to server).

#

i'm looking to accomplish an animated loading screen - something that doesnt freeze up

severe stirrup Sep 6, 2017, 2:12 PM

#

i haven't done it, but i think the basic idea is to set a travel level in your project settings

worthy wasp Sep 6, 2017, 2:14 PM

#

thats done - thats actually a requirement

#

but it still locks up when server transferring/connecting

tall grove Sep 6, 2017, 2:38 PM

#

how can server tells a specific client to perform a hud function?

hasty adder Sep 6, 2017, 2:42 PM

#

Broadcast to all but identify it by does ps = ps?

#

Guess it depends what the hud is indicating as to a best way to implement

twin juniper Sep 6, 2017, 2:49 PM

#

@tall grove how do you know which client you are looking for? if you have access to their pawn or playercontroller you can just simply call a client rpc on them.

tall grove Sep 6, 2017, 2:57 PM

#

i have my player character reference replicated (pawn) , client interacts with something , so server performs the interaction and does this player character reference run hud function , but right now when client do this , hud function is running on server and when i do on server i dont know where is running

twin juniper Sep 6, 2017, 3:00 PM

#

the client tells the server to start interaction? or is simulated?

#

ether way you can store the pawn reference like preforminteraction(mypawn) then when the server is done with its work it will simply do like mypawn->notifyInteractionComplete(float somedata) and notifyInteractionComplete is a client rpc which will talk to the hud at the end

twin juniper Sep 6, 2017, 6:08 PM

It crashs on a Shared Pointer

#

Multiple questions:

Do you have any Plugins in your Server Build?
Do you have any code that calls instantly on bootup?

viral mason Sep 6, 2017, 8:40 PM

#

I have two plugins

#

One of which is enabled (LowEntryExtStdLib)

#

Most of the things should have a delay

rancid current Sep 6, 2017, 8:40 PM

#

ah hey i would like to know if it would be okii for me to ask for advice here? xD

viral mason Sep 6, 2017, 8:41 PM

#

There is a "Event OnPostLogin" in the game mode

#

Player Character blueprint runs stuff directly on "Event BeginPlay"

thin stratus Sep 6, 2017, 8:41 PM

#

Hm, does it also crash if you start the Game from that Build?

viral mason Sep 6, 2017, 8:41 PM

#

other than that, don't think so

thin stratus Sep 6, 2017, 8:42 PM

#

So not the Server but the game exe?

#

GameInstance Init neither?

viral mason Sep 6, 2017, 8:42 PM

#

My game instance has just custom events I call from other things

#

So no

#

To be clear, I have a "Build folder"
So the files are at
W:\Unreal Projects\CODZombies\Build\Latest build\WindowsNoEditor

thin stratus Sep 6, 2017, 8:43 PM

#

The only thing I can think of is that it might be cause there are dlls missing

#

From Plugins

#

That's when it does that for me

viral mason Sep 6, 2017, 8:43 PM

#

hmm

thin stratus Sep 6, 2017, 8:43 PM

#

But you did package or?

#

Via Editor?

viral mason Sep 6, 2017, 8:43 PM

#

I packaged the project in editor

#

then i took the VStudio development server exe file and put it in the binaries folder w/ the game exe

thin stratus Sep 6, 2017, 8:44 PM

#

Yeah, and the package folder is the Build folder?

viral mason Sep 6, 2017, 8:44 PM

#

to be clear, it's a normal packaged game (non server)

#

yes

thin stratus Sep 6, 2017, 8:44 PM

then execute it

#

Actor?

rancid current Sep 6, 2017, 8:54 PM

#

Yes

thin stratus Sep 6, 2017, 8:57 PM

#

Is it set to replicate?

#

If yes, do you make sure it's spawned on the Server?

#

Because for passing an actor, you need the actor to be replicated and available on the other side

rancid current Sep 6, 2017, 8:58 PM

#

ah I have only replicated itself https://gyazo.com/65c33fba7956d84c637ab7b158c318f7 so yes it is

ItemToSpawn is replicated

twin juniper Sep 6, 2017, 9:07 PM

#

Does anyone know about UnrealScript?

thin stratus Sep 6, 2017, 9:08 PM

#

@rancid current No the Variable. the Actor CLASS you are spawning

#

You showed me that the PickUp thing is set to rpelicate

#

Is that Item Blueprint also replicated?

#

You are spawning it on BeginPlay, that calls on every Client and Server

rancid current Sep 6, 2017, 9:09 PM

#

One thing that i dont understand tho is that when the server does something the CLIENTS can see it without problems at all anything the server does, but if the client does something, the server wont see it which brings up the error that that its not getting the item data

https://gyazo.com/4aaacdd3a8812a1eae36e1daf102e5f0 and yes it is

Gyazo

thin stratus Sep 6, 2017, 9:09 PM

#

You should set it to replicate and then only let the server spawn it

#

SpawnManager?

#

Okay, slowly. You have "ItemToSpawn", right?
That Blueprint that you spawn there, so the Blueprint that is "ItemToSpawn", is that thing set to replicate?

#

Not the Variable or any manager

#

Just that Item

#

Is the blueprint marked as replicate

#

You should be SpawnManager and Pickup. I still want to see the Item

which the pickup and spawnmanager spawn on the world

thin stratus Sep 6, 2017, 9:14 PM

So this is the BP that you spawn in the ItemPickUp

rancid current Sep 6, 2017, 9:14 PM

#

yep

thin stratus Sep 6, 2017, 9:14 PM

#

Okay it's replicated, then please limit your BeginPlay call

#

To Server

#

As the Server spawning it will already spawn it on the Clients

rancid current Sep 6, 2017, 9:16 PM

#

hm.. how do i do that? 😅

thin stratus Sep 6, 2017, 9:17 PM

#

Use SwitchHasAuthority node

#

And since you don't know how to do that, grab my Compendium

rancid current Sep 6, 2017, 9:19 PM

if i set switchhasauthority the items do not spawn for the clients anymore

I think so, yes. I can post the result of the webapi call "GetServersAtAddress", as well as the client-side response from FindSessions if needed

sweet horizon Sep 7, 2017, 7:52 AM

#

Mm, using Unreal C++, does anyone know how to change the Steam server region as seen here?
{

"servers": [
{
"addr": <redacted>,

"appid":<redacted>,
"gamedir": <redacted>,
"region": -1,
"secure": true,
"lan": false,
"gameport": 7777,
"specport": 0
}
]

#

this is the output from the GetServersAtAddress steam webapi call

#

Apparently, the defualt region = -1 means the server will not be listed in the master server. However I haven't seen anything on how to change it using Unreal C++

BeaconConnectionInitialTimeout=90.0
BeaconConnectionTimeout=90.0

#

some other useful ini settings. its good to match the beacontimeout with your steam p2p timeout

twin juniper Sep 7, 2017, 7:24 PM

#

@thin stratus so you could use a beacon to send data to your server about how you want the character to look, before you spawn in

Yeah, using them already.
I have more trouble getting everything properly in line.

Things like: Does my host need a client too?

what are soem potential use cases for a beacon

#

lol

#

im curious

#

i might learn these

thin stratus Sep 7, 2017, 7:25 PM

#

A lobby in the main menu for example

#

Party that stays together to queue up

#

for matchmaking

#

and such things

#

the LobbyBeacon class has a GameState and PlayerState

#

But only the Client, so i guess my Host needs a client too

clever peak Sep 7, 2017, 7:26 PM

#

yes, you'll need a dummy beaconclient for the host, besides the hostobject and listener

#

you'll get a few engine crashes once you do that, just a heads up

@thin stratus You'll have to pull out of the base class some of the internal checks and rewrite it and skip through the super::class to the super's parent.

#

there's a couple hardcoded checks that will block you... hope that helps.

#

I had a real hard time doing it as a plugin, in abatron I just modified the engine which could be easier in your case.

why do they do it

jolly siren Sep 7, 2017, 8:37 PM

so people will stop using it

#

normally because it has been rewritten/redesigned/etc

twin juniper Sep 7, 2017, 8:39 PM

but

#

is it rewritten for performance?

or because someone has nothing to do at their job

so they rewrite functions?

like epic deprecated a function

about file paths

#

why?

makes no sense

File Paths functions

are soo simple

#

its literally

#

locate this file, by this string

#

whya re u deprecating a function like that

heady merlin Sep 7, 2017, 8:44 PM

#

likely because they consolidated it into a path library and didn't want people to use the old node

#

over time this way they can remove it entirely to avoid code and function bloat

#

if it wasn't done we would have 12 different legacy trace functions by now

viral mason Sep 7, 2017, 11:23 PM

#

Does anyone know how I can "pick" what IP a dedicated server listens on?

fossil spoke Sep 7, 2017, 11:25 PM

#

An dedi server doesnt "listen" to an IP, an dedi server has an IP and listens on an Port. When it recieves an message it would reply to the owner (IP) of that message

viral mason Sep 7, 2017, 11:25 PM

#

Well a lot of games you can pick the address the dedi listens to

#

like for example, if a dedi has 5 IPs available to it

#

you can pick if it uses IP 1, or IP 4

#

Let's say I throw it on a VM from my friends with ports exposed to the internet

#

Can any IP available to the dedi (so localhost, external, etc) go to it?

brittle sinew Sep 7, 2017, 11:28 PM

#

Yeah, you can choose what IP the server listens on like they said, like listening to 127.0.0.1 for only accepting localhost connections or 0.0.0.0/* to listen on all interfaces, for example @fossil spoke

#

That said, I've got no idea how to implement that in UE4.

#

:p

viral mason Sep 7, 2017, 11:28 PM

brittle sinew Sep 7, 2017, 11:33 PM

Does passing an IP as the URL when starting a server accomplish that?

Genuinely asking, I'm really not sure if that would work or not, haha

@brittle sinew haha, I was searching how to add gamepad support for packaged games and a question from you came up from July of last year. https://answers.unrealengine.com/questions/451299/add-controller-input-not-working-in-packaged-game.html
I'm trying to setup so one open packaged game has gamepad support (I.E I can move around while my keyboard/mouse is set to the other game)

#

I'd probably need to do split screen tbh

spark igloo Sep 8, 2017, 6:28 AM

Hi guys, In my game the server is spawning all the players so it has authority over all clients but this causes me that the animation is not replicating to other clients but the animation works properly if I used any button/key press and use switch has authority node. I need the animation to work properly on all the clients with out any button press but based on the data given to the player walk from UI. Need quick help on this

thin stratus Sep 8, 2017, 9:40 AM

#

@kodesu#4002 Spawning the Player Characters on the Server, while they are set to replicate, is correct.
You would then make sure that you specify an OWNER on the Spawn Actor node. This should be the PlayerController of the Player you are spawning it for.
Since you need that anyway for possessing, I assume you already have access to that.

For your Animations it could be that you are not properly replicating the required variables.

To replicate Animations inside of an Animation Blueprint, you have to make sure that the Variables that you get from your Character, are replicated.
NOT inside of the AnimBP, but already in the Character. Every local character has an AnimBP and pulls the data from the character. If you replicate the Data, you replicate the state machines.
Easy as that.

#

And I can't tag

#

@Latouth#3631 Split Screen is inside ONE packaged game on the same PC.
You are talking about 2 packaged games. What exactly are you trying?

#

spark igloo Sep 8, 2017, 10:37 AM

@thin stratus it tried to get the animation to work properly on the server side but on the client side the animation of the server is not updating . I used the replicated variables properly by setting them on the server. Event the log show that the values are replicated but the animation is not working on the client side.

thin stratus Sep 8, 2017, 10:42 AM

#

What exactly is not working on the client side?

#

Like what kind of animation

#

One that is inside a StateMachine, or a Montage?

spark igloo Sep 8, 2017, 10:46 AM

#

I had various animations of the character and based on the character speed I am using layered blend poses by bool node to switch the animation of the character.

#

On the client side the server animation is not playing

Quick question: when using PIE, if you tell the server to set a replicated variable, is there sometimes a delay due to lag, even in PIE with dedicated server on?

pallid mesa Sep 8, 2017, 8:50 PM

#

yes but you may review your code since it's pretty rare to have delayed behaviours on editor without simulating lag

#

@twin juniper gamesparks is free until you actually start earning

#

first 100k users free

smoky ore Sep 8, 2017, 8:55 PM

#

Well our bug was pretty rare to begin with. Making a function not rely on a certain replicated variable to be true seemed to fixed the issue

thin stratus Sep 8, 2017, 8:57 PM

#

@twin juniper GameSparks is a Website Service to save data of Players and maybe even manage some Matchmaking.

#

The Plugin allows you to communicate with it

#

It has nothing to do with Dedicated Servers

#

You could "abuse" it for that though

#

It would need you to add collections that keep track of your servers with sessions etc

#

Basically writing your own MasterServer

#

With GameSparks as Database

#

@smoky ore @vorixo#7101 You always have lags. Even in PIE. It's sending it after all.
It's really small, but it's there. If you set a Variable and instantly call a function that requries the variable to be replicated, you'll fail in PIE too

#

That's the point where you should pass the variable either via RPC

#

or use OnRep and call the code in the onrep function

smoky ore Sep 8, 2017, 9:08 PM

#

Well. I was in the process of stream lining the code that requires it. To the point where it didn't need it anymore. But tis nice to know these things ahead of tine

This is fun... dedicated server's...
I have my ue4 dedi on port 7777 with portforwarding setup

but i can't connect to it (windows btw)

brittle sinew Sep 8, 2017, 9:23 PM

#

Windows firewall?

#

Try this site: http://canyouseeme.org

#

If 7777 gives "connection refused", that means your port forwarding is working.

#

That just means the request is getting denied by the device, but that the request did make it to the device

#

If the request times out, it's probably an issue with your port forwarding

twin juniper Sep 8, 2017, 9:25 PM

#

its hard checking udp ports open on sites like that

brittle sinew Sep 8, 2017, 9:26 PM

#

Yeah, that's fair, I usually just forward both protocols just so I can test it, even if I'm not using TCP

twin juniper Sep 8, 2017, 9:26 PM

#

you would spend hours figuring out if the port is open but it actually is open all ya need is a fwend to connect

#

ya thats a good idea forwarding both

viral mason Sep 8, 2017, 9:38 PM

#

@brittle sinew its a "Connection timed out"

brittle sinew Sep 8, 2017, 9:39 PM

#

Okay, so that can occur in a couple of situations

viral mason Sep 8, 2017, 9:39 PM

#

to be clear, it's a Windows VM hosted by my friend

#

and he says he port forwarded UDP/TCP.

#

the ue4 server binary is open aswell

brittle sinew Sep 8, 2017, 9:39 PM

#

First possibility: you're simply not forwarding the port at the router. You can try any random port and it'll time out

#

Second possibility: the IP the port is forwarded to isn't accepting any connections. Try forwarding a port to some random IP, it'll time out

viral mason Sep 8, 2017, 9:40 PM

#

Well, he said he did it the same way as he did another port forward (and that one actually works)

brittle sinew Sep 8, 2017, 9:40 PM

#

I have a feeling the issue is more on the VM side than the port forwarding side.

#

Port forwarding itself is pretty hard to mess up...there are a lot more things that can get in the way

viral mason Sep 8, 2017, 9:40 PM

#

& That's to another VM/port

brittle sinew Sep 8, 2017, 9:42 PM

#

And well, I don't think I can help much if it's a "friend" doing it. Assuming that something is done correctly just because they said so and they "did it the same as before and it worked before" is dangerous

viral mason Sep 8, 2017, 9:43 PM

#

I think general networking issues is a little outside the scope of this area, but general debugging principles still apply in general

#

Isolate a problem area—is it only external connections that can get through? Can other computers on the same network access it? etc.

#

I'm going to bet it's an issue with the VM networking, and I haven't done a ton with Windows VMs

#

Also, make sure the port forward is pointing towards the right IP; bridged networking gives the VM its own network presence with its own IP (if it's using that)

#

A "timed out" error would suggest they're not pointing the port to the right IP (or not forwarding it at all).

sweet spire Sep 8, 2017, 10:43 PM

Heres a question, weapons like Orises fusion drive from overwatch, spawns a ton of projectiles, how is that handled?

heady merlin Sep 9, 2017, 1:37 PM

@wary willow you using the client side setup I have for that networked box or are you actually running it server side?

#

I had thoughts about just making a correctly replicated movement base for all of the objects in the base project you are using

jagged knot Sep 9, 2017, 1:40 PM

#

I'm kinda frustrated. After watching a dozen tutorials on the advanced sessions plugin, I still don't see the other player's pawn moving. (Player 1 clicks host and switches to game-map; P2 clicks join and SHOULD be visible to P1. The game-map's gamemode should spawn one pawn for every new player, which it does, but movement is only visible locally. Also, P2 will always spawn tilted like it hit something.)

#

if anyone has an idea, I beg you to share it

heady merlin Sep 9, 2017, 1:42 PM

#

are your pawns characters? or just "pawns"

jagged knot Sep 9, 2017, 1:42 PM

#

spaceship-pawns controlled by the basic playercontroller

heady merlin Sep 9, 2017, 1:43 PM

#

sooooo...they don't have a replicating movement component? Are you passing player input back to the server to replicate? If not...then no, no-one else will see their movement

jagged knot Sep 9, 2017, 1:45 PM

#

I thought replicating the mesh itself would include world position, it seems to work in most tutorials

heady merlin Sep 9, 2017, 1:45 PM

#

down from the server yes

#

up from the client...no

#

also its not predicted or corrected, so there is that too

jagged knot Sep 9, 2017, 1:47 PM

#

so if I replicate the pawn itself, the mesh and replicate movement it should work?

heady merlin Sep 9, 2017, 1:49 PM

#

not exactly

jagged knot Sep 9, 2017, 1:49 PM

#

And I'm not using dedicated servers, just a session

heady merlin Sep 9, 2017, 1:49 PM

#

you would be a lot better off trying to work off of a character if possible

#

otherwise you will end up having to do a lot of this yourself

#

if you are serious about working off of a pawn

#

you'd want to look at Uwheeledvehicle and WheeledVehicleMovementComponent

#

to see how they run the player input both locally, and replicate it to the server as well

#

if you pass input to the server then players actions will be delayed by the ping, which will feel terrible

ping doesn't affect my game a lot, up to 5 seconds delay would not be noticeable

5 second delay from input to action?

#

unless its turn based, that sounds intolerable

if P1 presses a button, then P1 should directly see it. P2 doesn't need that information too quickly.
