I'm doing that right now. And right now I got my answer. I can only use a couple of predefined varaibles apparently. So no, my idea won't work.

teal crest Jun 21, 2018, 12:11 AM

#

We'd need more information to help you. Who triggers the weapon change initially, the client? The authority? How is your weapon state stored?

glacial lotus Jun 21, 2018, 12:13 AM

#

Yes it woould be the client the one that triggers the change. Authority I don't know... playre are clients so I guess they don't have auth. And the weapon stuff is stored in a struct that's part of a component into the characters.

teal crest Jun 21, 2018, 12:14 AM

#

Again I'm not an expert, but I'd read the part about Player state and how it's replicated in the compendium. That seems like a good place to store player specific replication state. Otherwise you could just replicate pieces of the pawn.

glacial lotus Jun 21, 2018, 12:15 AM

ok, thanks

Have you guys saw the Unreal's main page displaying the MMO for mobile?

#

i always wondered whether these MMO's character are all basically tiny sized in the first place?

#

Like basically smaller than typical PC's character size

#

I mean I don't get how they make it work on mobile lol

anyone know why UGameInstance::GetPrimaryPlayerController checks PlayerState->UniqueId.IsValid()? It makes it return null during demo replays because demo controllers won't have a valid uniqueid
I'm trying to work around it, but I don't know what the rationale of it is

I don't want to break some other feature by using a version without the check

@thin stratus how would i solve it?

so any suggestions as to how to solve it?

thin stratus Jun 21, 2018, 6:07 AM

#

Yeah well, for a Lerp youd need a Timeline, so you have to interp I guess

#

Put the interp into your tick

#

And toggle it with a boolean

umbral adder Jun 21, 2018, 6:07 AM

#

ok

thin stratus Jun 21, 2018, 6:07 AM

#

Which you can set in the hit event

umbral adder Jun 21, 2018, 6:08 AM

#

that seems a bit bad practise 😮

thin stratus Jun 21, 2018, 6:08 AM

#

You could also try to set up the timeline in your Character

umbral adder Jun 21, 2018, 6:09 AM

#

np ill make a bool

thin stratus Jun 21, 2018, 6:09 AM

#

Not bad practice if epic doesnt allow the timelines

umbral adder Jun 21, 2018, 6:09 AM

#

should i use finterp to?

#

😄

thin stratus Jun 21, 2018, 6:09 AM

If you want to interp a float, yes

Hey guys,
how would i go about making a secure store/player data with dedicated servers (can be anything even php)

-Decode

tender gale Jun 21, 2018, 9:02 AM

#

Anyone have any information on how to add client side prediction to custom values on objects? I.e. say I have an in world object which represents a weapon and it has an ammo count and I want to predict that ammo count going down when firing the weapon. Is this something that the default networking system will be able to do for me or does it require a custom solution?

#

I know for example the CharacterMoveController can do client side prediction by default on the players movement, and that's great. But usually you end up wanting to predict more data for your player than just that.

#

And even predicting other objects in the world, like picking up a weapon and predicting it's ammo when firing it.

keen halo Jun 21, 2018, 9:13 AM

#

Maybe I missunderstand you, but you are not confusing prediction with replication are you?
Why would need to "predict" ammo going down when you can just reduce the ammo count server-side , and replicate the new ammo count down to clients?

tender gale Jun 21, 2018, 9:13 AM

#

@keen halo Well, sure. But that creates a significant (ping-dependant) delay on the ammo going down

#

I am not confusing prediction and replication 😃

#

You could say, okey but that's just a UI thing for one player, you could 'predict' that locally in the UI and then patch it up when you get the updates, etc.

#

I'm using the 'weapon with ammo' as an example of course, there's more complex prediction scenarios you might want to do.

keen halo Jun 21, 2018, 9:18 AM

#

@tender gale Have you considered using delegates for letting the client know about changed variables instead of replication?

tender gale Jun 21, 2018, 9:20 AM

#

Sure, but that adds significant overhead in terms of bandwidth for something as small as updating an ammo counter

fleet sluice Jun 21, 2018, 9:20 AM

#

@tender gale There was a rather lengthy conversation in this channel yesterday, where 2 guys and I wrote our approaches. Scroll up a bit or search for "prediction".

tender gale Jun 21, 2018, 9:22 AM

#

@fleet sluice thanks, but the idea of using RPCs/etc. to do this seems like a huge work around which complicates the code base massively

fleet sluice Jun 21, 2018, 9:26 AM

#

A workaround to what? You don't have a built-in solution for anything apart from the CMC class, which is, more or less, based on a similar approach.

tender gale Jun 21, 2018, 9:26 AM

#

A work around to being able to have the clients automatically predict local values of actors

#

And then have it automatically reconcile with the server

#

For something like movement yeah you usually need a custom solution due to it needing to be aboslutely 100% smooth for the playing client

fleet sluice Jun 21, 2018, 9:27 AM

#

Replication isn't a solution for anything, anywhere at any times. Treat it as such and you end up with PUBG/ARK/CE-type of networking. You can't have your cake and it too.

#

You should Google prediction and read the PDFs you find and you'll end up with the same approach.

tender gale Jun 21, 2018, 9:28 AM

#

I'm a very well experienced networking engineer, I've implemented networking for a lot of games, and built whole networking libraries from scratch. I've just never done it in Unreal, which is why I asked.

fleet sluice Jun 21, 2018, 9:29 AM

#

(I read tens, if not hundreds of pages on the subject, most not even UE4-related)

tender gale Jun 21, 2018, 9:30 AM

#

And being able to locally predict 'replicate' values is something I've used to great effect before, since it simplifies so much code around stuff like this and lets the networking subsytem handle it for you automatically

fleet sluice Jun 21, 2018, 9:30 AM

#

Then I guess it won't take you long to realize the ups and downs of replication.

tender gale Jun 21, 2018, 9:31 AM

#

So I simply asked if it's possible to do this in Unreal, since I've built and used system like that before. So it's not, I'll have to come up with a custom solution.

bitter oriole Jun 21, 2018, 9:43 AM

#

@tender gale The UE replication treats replicated variable as a server-to-clients mechanism, and RPC as a client-to-server mechanism, basically

tender gale Jun 21, 2018, 9:44 AM

#

@bitter oriole Yeah that's pretty standard I would say, whoever 'owns' the actor is allowed to replicate it

bitter oriole Jun 21, 2018, 9:44 AM

#

For client-triggered actions it's common to process stuff locally, fire the RPC and reconcile server replication later

#

But you'll need to implement prediction yourself

thin stratus Jun 21, 2018, 9:45 AM

#

@tender gale Just call your fire code locally first

bitter oriole Jun 21, 2018, 9:45 AM

#

There is no built-in mechanism except for character movement

tender gale Jun 21, 2018, 9:45 AM

#

Okey, cool... that's all I wanted to know 😃

bitter oriole Jun 21, 2018, 9:47 AM

#

The typical approach for that like cedric said is, just call stuff locally immediately, and fire it up on the server too

#

Like you'd update the ammo count immediately when firing, server does too, and when the server replicates down, you'd reconcile the different values with a history

#

Like you do for movement

twin juniper Jun 21, 2018, 11:10 AM

About the Use Single Process option when using multiplayer, when or why should one test it with that option disabled?

#

Does anyone know how to fix the multiplayer spawning issue where sometimes your character doesnt spawn

#

ive been stuck on this for a while now 😦

calm hound Jun 21, 2018, 12:22 PM

#

You're going to have to be a lot more specific than that.

strong breach Jun 21, 2018, 12:37 PM

#

@calm hound im getting the Character cant spawn because of collision error sometimes because two characters are spawning at the same place

calm hound Jun 21, 2018, 12:40 PM

#

Why are you trying to spawn two characters in the same place?

#

The game automatically tries to move the actor a bit to avoid collision during spawning, if it's a tight spot it'll fail and not find an alternative place to put the other player. So you need to have a separate player start for the other player

keen halo Jun 21, 2018, 12:45 PM

#

@strong breach You can check your SpawnCollisionHandlingMethod in your actor properties - but as @calm hound said, it is probably better to spawn them on different places.

calm hound Jun 21, 2018, 12:46 PM

#

I believe in SpawnActor() you can also set bForceSpawn or something, but I imagine overlapping collision will cause a lot of issues

strong breach Jun 21, 2018, 12:47 PM

#

i tried moving the spawns before but ill do it again just to be sure

#

and I changed the spawncolhandlingmethod to adjust location but always spawn and it still doesnt work 😦

ripe raptor Jun 21, 2018, 12:51 PM

Would someone be so kind as to help me diagnose why Steam is not working in my game?

#

What's the problem

ripe raptor Jun 21, 2018, 12:56 PM

#

well, it compiles properly, the plugin is enabled, the appid is set up, the sdk binaries are in their proper position, but the damn overlay is not showing up

strong breach Jun 21, 2018, 12:56 PM

#

what overlay?

ripe raptor Jun 21, 2018, 12:57 PM

#

The Steam overlay

strong breach Jun 21, 2018, 12:57 PM

#

and is steam open when you start the game

ripe raptor Jun 21, 2018, 12:57 PM

#

And I am running it as stand alone

#

and yes

strong breach Jun 21, 2018, 12:57 PM

#

ok thats bad lol

#

try adding the appid and subsystem again

#

recompile maybe?

#

usually you should test that first before continuing

bitter oriole Jun 21, 2018, 12:58 PM

#

@ripe raptor Is it a shipping build ?

ripe raptor Jun 21, 2018, 12:58 PM

#

It's just "run as standalone" from the editor

bitter oriole Jun 21, 2018, 12:59 PM

#

Tried running it outside the editor ?

#

Launch from the .uproject

strong breach Jun 21, 2018, 12:59 PM

#

the overlay doesnt show up for me as a standalone

#

but its there when i build it

ripe raptor Jun 21, 2018, 1:00 PM

#

hm, that doesn't sound right, always appeared for me in standalone

#

but let me test

bitter oriole Jun 21, 2018, 1:00 PM

#

My take is that on shipping you need to start it from Steam

#

Still no idea on which build type is used when you launch

#

From editor, I guess it's the "package type" setting

#

From the .uproject, dunno

ripe raptor Jun 21, 2018, 1:06 PM

#

let's see if it works from a build

strong breach Jun 21, 2018, 1:14 PM

#

i knowit wont work from the editor

#

so im guessing standalone counts as the editor ?

bitter oriole Jun 21, 2018, 1:17 PM

#

No, shouldn't

#

It's an entirely new process

ripe raptor Jun 21, 2018, 1:22 PM

#

It always worked in standalone

#

but I am compiling a release build just because

#

will check it through that as well

SpawnActor failed because of collision at the spawn location [X=-950.000 Y=-333.000 Z=4712.001] this is the network player start error im getting if anyone is familiar with it

calm hound Jun 21, 2018, 1:35 PM

#

It's just telling you where in the world the collision check failed to find a proper place to spawn

#

what's your spawn area look like? Is it crowded?

strong breach Jun 21, 2018, 1:36 PM

#

nope

#

i put it high up (the z value is 4700) and its still not working

#

and i set it to always spawn

calm hound Jun 21, 2018, 1:37 PM

#

are you spawning both players at the same time in the same function?

#

What's your spawning code/blueprint look like

strong breach Jun 21, 2018, 1:39 PM

#

its the default code

#

is there a way i can override it

#

i only added the player start

calm hound Jun 21, 2018, 1:48 PM

#

You can, but if you're using the default it should work unless the character you're trying to spawn is way bigger than a default character is?

#

do you have a 2nd player start? If you add 2, it'll try to move to the next one if the first doesn't work

strong breach Jun 21, 2018, 1:53 PM

#

its twice as big as a regular player

#

and i put like 8 player starts

#

im using network player start if that changes anything

calm hound Jun 21, 2018, 1:57 PM

#

It's probably the size difference that's failing

#

the code only extends so far X and Y when trying to find a collision spot, by default that X and Y extension is based on their default scaling. Scaling things up twice as much, means your collision expands twice as much as they're expecting. So they're running into the other player's bounds because they don't extend that far out

strong breach Jun 21, 2018, 2:00 PM

#

oh ok ill try that then

#

@calm hound yup same issue

Is there any way to register if the client stops sending movement replication updates to the server? The pawn that the client controls sometimes stops replicating its movement to the server, while the client can move without any issues, the server doesn't update his position, and it is pretty game-breaking for me

How would you go about setting up a multiplayer main menu (I already know how to do game replication etc) but What I'm a bit lost on is how I can have everyone in say a region (NA or whatever) is connected to when they launch the game, then from the main menu they can see their in game currency, profile data & stats (kills deaths etc).

#

In simpler terms I'm trying to create a 'launcher/menu' similar to that of league of legends so your connected to a server and then when you join a match you connect to a different server

Newbie here. So how of a bad idea is this? https://blueprintue.com/blueprint/ec5ei17p/

BlueprintUE.com

anonymous

change weapon replicated

#

It's the event to physically change the weapon and update the HUD (after the logic is done, temporarily, in the client. I'll move the logic to the server soon)

#

oh, in blueprintue.com the "run on server" info and similar don't appear 😦 Not cool

Well, the Server event is "run on server" and the "multicast" is .... multicasting 😃

In terms of default functionality, as long as you call your supers and don't mess with internal stuff (if you're in BP that'd probably be hard to pull off even if you tried), it will stay the same.

Unfortunately it doesn't say much more

thin stratus Jun 22, 2018, 8:38 AM

#

Do you use the default version

#

Or an updated steamworks

ripe raptor Jun 22, 2018, 8:38 AM

#

I've updated steamworks to 141 and I've edited the Steamworks plugin to use that

thin stratus Jun 22, 2018, 8:39 AM

#

Alright and the other project worked?

ripe raptor Jun 22, 2018, 8:39 AM

#

yup

thin stratus Jun 22, 2018, 8:39 AM

#

Any files you added to the other project?

#

That you might have forgotten

ripe raptor Jun 22, 2018, 8:41 AM

#

I've placed the steam sdk into the thirdparty binaries... but that's about it.

thin stratus Jun 22, 2018, 8:41 AM

#

Hmm

#

So:

Plugin Enabled
Plugin Updated
Steamworks files added
DefaultEngine.ini updated fully

ripe raptor Jun 22, 2018, 8:43 AM

#

hm, just to check - the plugin I am looking for is OnlineSubsystemSteam, correct?

#

If yes then yes on first one

#

it's up-to-date with my engine installation

#

That's the config stuff

thin stratus Jun 22, 2018, 8:50 AM

#

!NetDriverDefinitions=ClearArray

#

Can you put that before your +NetDriverDefinitions

#

Also +NetDriverDefinitions=(DefName="GameNetDriver",DriverClassName="OnlineSubsystemSteam.SteamNetDriver",DriverClassNameFallback="OnlineSubsystemUtils.IpNetDriver")

#

That's what I have in a 4.19 project

#

So without the /Script

#

Cause you define the netConnectionClassName without /Script too

ripe raptor Jun 22, 2018, 8:51 AM

#

That's what I had previously, but I was missing the cleararray line. Let me try with that

#

Unfortunately no difference

#

This is an engine source build if it makes any difference

#

I'm looking at the Steamworks.build.cs tryin to find any irregularities

fleet sluice Jun 22, 2018, 9:04 AM

#

That error comes from a failed initialization which is done in the OSSteam module interface. The NetDriver has nothing to do with it. I vaguely remember the path to the SDk was hard-coded in 2 places and I think the 2nd was in the OnlineSubsystemSteam.build.cs file or in the module interface's .cpp.

ripe raptor Jun 22, 2018, 9:05 AM

#

It's in OnlineSubsystemSteam.Build.cs and I've already changed it to Steamv141

fleet sluice Jun 22, 2018, 9:06 AM

#

What about Steamworks.build.cs? Doesn't that also link to the SDK? I'm not at my PC at the moment.

ripe raptor Jun 22, 2018, 9:07 AM

#

string SteamVersion = "v141";

#

=/

fleet sluice Jun 22, 2018, 9:08 AM

#

You could do a full project search for "139” just to make sure you're not missing it anywhere.

ripe raptor Jun 22, 2018, 9:08 AM

#

Just added a console write to OSSSteam.build.cs and yes, it finds the directory

fleet sluice Jun 22, 2018, 9:09 AM

#

Is the log you posted above complete? Nothing extra before that?

#

Also, did you create the `steam_appid.txt' file in your packaged projects?

ripe raptor Jun 22, 2018, 9:11 AM

#

yup

#

as for the log

#

I can see that the OSSSteam is being mounted by the plugin manager

#

I see that the module manager loads it

#

There are these, but they don't seem to be steam related:

#

@fleet sluice Is that in response to my question?

stable kindle Jun 22, 2018, 10:02 AM

#

Hey guys so have a weird problem that i believe could be something simple

#

I have a Replicated component that i have on my Pawn. I use said component on other actors that follow the pawn. This component sets the location and does a few movement calculations. The problem is On the client i can see the other actors that are dependent on the said component move correctly but no the pawn itself. The Pawn moves as expected on the server.

#

I feel like i've mucked up something very basic....

#

The other actors also use the same component to move as the pawn

fleet sluice Jun 22, 2018, 10:10 AM

#

@twin juniper Yea. I'm not sure if it does anything, but probably better for someome else to confirm/deny it.

twin juniper Jun 22, 2018, 10:35 AM

#

@fleet sluice Well, it does do things. Not sure if it is relevant though to testing lag compensation techniques or not...

Use the net stats commands to test those. One sec.

Hey I have been strugling to replicate the movement of a ball that players hit smoothly any advice, the ball is a physics object and the players hit it with collision detection in an animation I heard that you can make a Child class of the character movement component but am struggling to find any information how :?

thin stratus Jun 22, 2018, 1:49 PM

#

Well, with Child Class of CMC it means that you just inherit from it

#

In C++

twin juniper Jun 22, 2018, 1:59 PM

#

I have an issue. I have it to where whenever a player sprints/Aims down sights it speeds them up and slows them down. When I test multiplayer, only the host's movement speed is changed while off host is not. What's strange is, I also have the same script adjusting camera boom & the animation that the player is using and that one seems to work just fine on or off host.

#

Here is my sprint blueprint

📎 unknown.png

#

and here is the "start sprint" blueprint

📎 unknown.png

#

My aim down sights blueprint is the exact same

twin juniper Jun 22, 2018, 2:29 PM

#

if there is any other information you need let me know.

sly basin Jun 22, 2018, 2:43 PM

#

because without server setting max speed it doesn't register. if you were to set it on server it would work in multiplayer. One way around this is to set the max speed to the highest possible and then use a multiplier to change speeds instead of tryign to change the max. there could be a more elegant solution but it will work

twin juniper Jun 22, 2018, 2:51 PM

#

Alright

#

I'll give it a shot. Thanks.

sly basin Jun 22, 2018, 2:54 PM

#

ran into the same thing a while back. I didn't want to wait for the server rpc for him to start sprinting locally so I just set it at the max and multiplied the scale on add movement input by a variable. x 1 for max and .5 for half. etc, gets the job done for now.

calm hound Jun 22, 2018, 3:03 PM

#

Yeah, that's a hard-coded replicated variable. Try to adjust it locally results in rubberbanding quickly.

#

movement speed is controlled by Server

twin juniper Jun 22, 2018, 3:27 PM

#

Okay, so wait, could you post a picture of what the blueprint would look like? Sorry, I'm really new to this.

#

@sly basin

#

I mainly just need to know the nodes involved in multiplying movement speed

#

From there I can get it set up on my own

twin juniper Jun 22, 2018, 4:11 PM

#

I spawn two players through custom game mode and I am using DrawDebugString to print visually their role. It is only showing their own role, and on the other pawns it doesn't show SimulatedProxy. Any idea why?

#

Yeah, no pawn has the role of simulated proxy... How can this be? If it is spawned on the server and replicated, it should have simulated versions of it, right?

winged badger Jun 22, 2018, 4:48 PM

#

and you print from inside the GameMode?

twin juniper Jun 22, 2018, 4:56 PM

#

@winged badger No, I print on the Pawn tick

#

On the server side I get Authority for both pawns, on the client side only get Autonomous Proxy for the local one, the other pawn doesn't even show role

winged badger Jun 22, 2018, 4:59 PM

#

those are Player controlled Pawns?

twin juniper Jun 22, 2018, 5:00 PM

#

Yes

winged badger Jun 22, 2018, 5:00 PM

#

and if you just drop one of those in the level instead of spawning them, it shows the correct role?

#

not possessed by a PC

twin juniper Jun 22, 2018, 5:01 PM

#

I run a server function on GameMode and on that function, after spawning the pawn I use the Posess function

winged badger Jun 22, 2018, 5:02 PM

#

i wasn't ever really interesting to know if something is a Role == Simulated_Proxy so i never tried what you're doing now

#

i am assuming the problem is with your client not having the host's PC around

twin juniper Jun 22, 2018, 5:03 PM

#

Yeah, probably is that, but I always did this this way, and it's the way shown in tutorials and it doesn't work now...

winged badger Jun 22, 2018, 5:03 PM

#

well, it has an int8 value

#

the enumerator

#

so you could do if Role < ROLE_Authority checks

#

i do think if you took your PlayerPawn and just dragged it into the level, unpossessed from the content browser

#

it would show the role correctly, that its just limited to displaying role on actors owned by other players

twin juniper Jun 22, 2018, 5:10 PM

#

This is way too weird...

#

I mean, this code worked previously...

I mean, this code worked previously...

icy nacelle Jun 22, 2018, 5:38 PM

If I set a timer by running on server, will it do all the functionality on the timer on the server, or should I put in RPC into the timer instead?

(Hope that makes sense lol)

Hey guys I'm overwhelemd with options for starting a VR multiplayer shooter game. Should I start with the Shooter Game example, should I start with Proteus VR, should I just start from scratch? Any advice?

twin juniper Jun 22, 2018, 6:06 PM

#

How is it possible that I get owner role as Authority and the owner remote role as AutonomousProxy...?

bitter oriole Jun 22, 2018, 6:07 PM

#

That's expected for a pawn

#

autonomous = basically a player-copntrolled pawn

#

on the client

calm hound Jun 22, 2018, 6:08 PM

#

@icy nacelle Same logic applies to any other code. If you start a timer on the server, only the server will run the timer, but if your timer calls a NetMulticast or Client function for example, the server will still call it to clients

twin juniper Jun 22, 2018, 6:08 PM

#

@bitter oriole No, the owner remote role should be Simulated Proxy...

bitter oriole Jun 22, 2018, 6:08 PM

#

Depends on the actor

#

For a pawn it should be AutonomousProxy remote, Authority on server

twin juniper Jun 22, 2018, 6:09 PM

#

If I am testing on the server own pawn, its remote role should be SimulatedProxy

icy nacelle Jun 22, 2018, 6:09 PM

#

@calm hound Thanks mate

bitter oriole Jun 22, 2018, 6:10 PM

#

@twin juniper If you have a listen server, then yeah.

twin juniper Jun 22, 2018, 6:10 PM

#

Yeah, I have a listen server

#

That's why it doesn't make any sense

calm hound Jun 22, 2018, 6:11 PM

#

But you're playing as the server when you run a listen server

#

so your Role would be Authority because you're technically the server

#

where all other clients, their Role (from their perspective) would be Autonomous, because they're actual clients

bitter oriole Jun 22, 2018, 6:13 PM

#

@twin juniper I know there's something fishy on that if you use GameModeBase

icy nacelle Jun 22, 2018, 6:13 PM

#

So that seemed to work, although when the timer is finished, it starts a new timer. That seems to not be working. Surely this is already running on a multicast?

bitter oriole Jun 22, 2018, 6:13 PM

#

I actually have this in my pawn class to fix something related : if (GetNetMode() != NM_Standalone && Cast<APlayerController>(Controller)) { if (Cast<APlayerController>(Controller)->GetRemoteRole() == ROLE_AutonomousProxy) { SetAutonomousProxy(true); } else { SetAutonomousProxy(false); } }

#

Basically copy the proxy setting from the PC

#

That's in PossessedBy

calm hound Jun 22, 2018, 6:16 PM

you mean it doesn't loop?

icy nacelle Jun 22, 2018, 6:16 PM

#

The second timer doesn't start

#

The loop works fine, but you see the second timer gets started in the second screenshot?

calm hound Jun 22, 2018, 6:16 PM

you're clearing it and setting it at the same time thoguh

#

oh wait

#

sorry

icy nacelle Jun 22, 2018, 6:16 PM

#

np

#

😉

#

So for some reason, it just doesnt like that, but surely its still being multicasted?

calm hound Jun 22, 2018, 6:18 PM

#

does that 2nd timer get called at all?

#

on any version?

icy nacelle Jun 22, 2018, 6:18 PM

#

Yeah, singleplayer this stuff works perfectly

calm hound Jun 22, 2018, 6:20 PM

#

I don't see anything wrong wtih the call

#

might be something inside the RetractTimer

#

but

#

one thing to keep in mind with Multicast

#

is that it's based on Relevancy. If the actor isn't relevant it won't replicate

#

bReplicates need to be turned on, relevancy distance needs to be good, etc

#

also

#

your BeginPlay may be the issue

#

BeginPlay() is usually a bad place to call any sort of replicated call to be honest, things are still syncing

Completely fresh 4.19 project

icy nacelle Jun 22, 2018, 6:24 PM

#

hmm, not sure where else to do it, as its a projectile class

#

Timer is relatively the same as the first one

#

All my replication boxes are ticked

calm hound Jun 22, 2018, 6:25 PM

#

you're spawning a projectile class?

icy nacelle Jun 22, 2018, 6:25 PM

#

Yeah

calm hound Jun 22, 2018, 6:25 PM

#

is the server spawning it?

icy nacelle Jun 22, 2018, 6:25 PM

#

Yeah

calm hound Jun 22, 2018, 6:26 PM

#

are you setting the client as the owner?

icy nacelle Jun 22, 2018, 6:26 PM

#

Ah, no I'm not..

calm hound Jun 22, 2018, 6:26 PM

#

The client can't call Server functions unless some where in it's Owner chain is a Player Controller

icy nacelle Jun 22, 2018, 6:27 PM

#

hmmm

#

But the projectile is spawned on the controller

#

The weapon runs an event on the controller which spawns the projectile

calm hound Jun 22, 2018, 6:29 PM

#

I believe you have to specify the owner still

#

Either

#

A. You're calling the SpawnProjectile from the client, and it's all local and the server never spawns an object

#

or

#

B. You're calling a RPC to spawn it on the Server, and the Server owns it

#

be my guess

icy nacelle Jun 22, 2018, 6:31 PM

#

Maybe I should better explain what I'm doing and the problems that I'm having. When I spawn the projectile on a client, the projectile's first timer works perfectly, but the second timer does not work, it kinda flings the player about (it should be moving just the projectile not the player)

calm hound Jun 22, 2018, 6:33 PM

#

Log it

#

add a Print Screen node to various parts in your code, especially the functions that get called by the Timers, and see who's calling what

#

it should tell you if the function is being called by the Server, or the Client, or both

icy nacelle Jun 22, 2018, 6:34 PM

#

Okay, and I assume I want it to be printing on both server and client(s)?

calm hound Jun 22, 2018, 6:35 PM

#

mmm

#

I don't think so

#

well

#

with what you're currently trying to do

#

yes

#

it should be called on both

icy nacelle Jun 22, 2018, 6:35 PM

#

Okay, both timers get called on the client and server

calm hound Jun 22, 2018, 6:36 PM

#

so then your problem sits with your RetractTimer function probably

icy nacelle Jun 22, 2018, 6:38 PM

#

Strange, because the whole thing works perfectly on singleplayer - and RetractTimer is almost the same as the first timer

calm hound Jun 22, 2018, 6:41 PM

#

well typically server controls location of things

#

so you're probably having the client and the server trying to move the same thing, and the server is replicating the movement back and it's causing the client to have issues

#

I dunno

icy nacelle Jun 22, 2018, 6:43 PM

#

Alright, thanks for the help. I think I'll just have an intense look deep down into every node and have a good pick at it. Cheers.

calm hound Jun 22, 2018, 6:43 PM

#

👌

fringe dove Jun 22, 2018, 6:53 PM

#

when you first join a server, you get only a local player controller until the main one is replicated from the server right? and then it does some kind of weird object swap?

#

so if you call a server RPC on that local controller before it has been swapped with the replicated one, it just gets dropped? or not?

worn nymph Jun 22, 2018, 6:53 PM

#

@hollow patrol your starting it in the wrong place it has to be in the binaries folder

Doubtful

#

Looks more like something drastic like 32 v 64b

hollow patrol Jun 22, 2018, 6:57 PM

#

Im on win64, build was done for win64

#

not sure what else it could be, other devs on the project getting the same thing when running.

bitter oriole Jun 22, 2018, 6:58 PM

#

So how did you package it ?

calm hound Jun 22, 2018, 6:59 PM

#

@fringe dove if you call an RPC on a local controller, that the server doesn't know about. It just gets ignored

#

PostLogin() I believe is the first safe place to call replicated functions for a joining player

fringe dove Jun 22, 2018, 7:03 PM

#

@calm hound how about on the client though? postlogin is only on the server right?

calm hound Jun 22, 2018, 7:04 PM

#

depends entirely on what you're trying to do.

#

If the player hasn't joined yet, don't call RPCs

#

typically control isn't available to the player until they're actually connected?

fringe dove Jun 22, 2018, 7:07 PM

#

@calm hound I'm not sure if control is available in that temporary player controller or not

#

but in my case, I get an event (VR enabled), and try to tell the server about it when it happens

#

I'll have to look into it more, but I guess I'll have to defer sending that event until the player controller has been swapped with the replicated one

#

I'm not quite sure that's what's going on, I just remember seeing that swap in the code somewhere

calm hound Jun 22, 2018, 7:09 PM

#

so what are you trying to do?

#

PostLogin() only gets called on the server, BeginPlay() gets called on both, but BeginPlay() doesn't mean it's replicated fully yet. Typically if you're trying to do logic during connection like that

#

you call a Client function via PostLogin() that activates whatever you need for the client when they first join

fringe dove Jun 22, 2018, 7:16 PM

#

Any time I put on or take off a VR headset, I send a vrenabled rpc

#

and also when the game first starts up I think I send one pretty early

#

maybe before the PC has replicated

#

I'll try that client rpc thing with postlogin

#

and move some of my startup logic that sends server RPCs into there

calm hound Jun 22, 2018, 7:17 PM

#

so then you probably would want to check their VR status after PostLogin VIA a Client RPC

hollow patrol Jun 22, 2018, 7:17 PM

#

@bitter oriole Just through Project launcher in editor

fringe dove Jun 22, 2018, 7:23 PM

#

yeah looks like I always had an initial vr state changed event with the current status inside PostInitializeComponents; I'm pretty sure it was happening with the dummy PC, RPC dropped, then that PC got swapped out with the real one, and that swap operation probably doesn't call PostInitializeComponents again

#

I'm not sure though, looks like swap player controller may only be used on seamless travel and not initial conneection

calm hound Jun 22, 2018, 7:23 PM

#

That's a bit beyond me. Player Controllers are one of those magical things 😛

#

but I believe 2 things always need to be present, a Map and a Controller

#

so how they handle the swapping of a controller during connection is beyond me

#

I believe you can mark certain variables Transient, which means it stays the same while you're changing/loading/switching maps, dunno about connection though

but Server_ it's called on server side no ?

all networking functions will be right above or below it

I see only ClientAdjustPosition_Implementation and ClientVeryShortAdjustPosition_Implementation nothing else

and still something else is called to adjust client postion to server position

Has anyone here implemented seamless travel between different servers? Imagine World of Warcraft questing zones, not dungeons!

Not to be confused with seamless travel between different levels on the same server!

tawny parcel Jun 23, 2018, 8:55 AM

#

@fleet sluice World composition, you can youtube some battleroyale tutorials and it should come up

fleet sluice Jun 23, 2018, 9:05 AM

#

@tawny parcel Thanks, but that'a not relevant for multiplayer.

tawny parcel Jun 23, 2018, 9:06 AM

#

@fleet sluice Its is actually, atleast its working for me

#

@fleet sluice I would find it odd that several battle royale tutorials would utilize if it didnt work too

fleet sluice Jun 23, 2018, 9:07 AM

#

Yea, but it's based on the premise that you want a single server to manage the entire world. It's not what I want. I want totally different levels, on totally different servers, with a synchronized "border".

tawny parcel Jun 23, 2018, 9:08 AM

#

I see, hmm, thats clearly a bit different

fleet sluice Jun 23, 2018, 9:09 AM

#

I've seen most multiplayer/networking tutorials and my opinion is that they are shit and based on a "minimum viable product" mentality, which I don't adhere to (yes, I am aware the whole phrase sounded arrogant).

#

And I did search again before replying, just to make sure I wasn't missing anything.

tawny parcel Jun 23, 2018, 9:09 AM

#

I feel ya man, its been tough getting in to the networking side but I went the same path

fleet sluice Jun 23, 2018, 9:10 AM

#

With a single map on a single server, you can't distribute loads, no matter how much something like world composition helps.

tawny parcel Jun 23, 2018, 9:10 AM

#

Pays off tho, made a fun multiplayer game for the last game jam

#

Yea I totally get all that I'm tossing the idea in my head on how it might be doable

fleet sluice Jun 23, 2018, 9:11 AM

#

Ideally, your huge ass map (WoW style) would be hosted by several servers, at least 2 per zone/server, on different VMs, in case on crashes.

bitter oriole Jun 23, 2018, 9:13 AM

#

@fleet sluice Seamlessly migrating players from servers without a loading menu inbetween is going to be a tough job

fleet sluice Jun 23, 2018, 9:13 AM

#

Yea, I get that feeling as well.

#

I've been thinking about various ways to implement my own solution, but I thought it would be wiser to ask first, in case someone else had done it before.

bitter oriole Jun 23, 2018, 9:14 AM

#

The usual question here is, does your editor has a marketing budget large enough that you'll need load balancing on multiple servers ?

fleet sluice Jun 23, 2018, 9:15 AM

#

I'm a loner ✅ I'm thinking of Marketplace opportunities.

#

I've seen various MMO "solutions", which don't really quality as solution, in my vision. I think there's room for someone to jump to the next level.

thin stratus Jun 23, 2018, 9:16 AM

#

Hm

#

I dont think this qualifies as seamless though

tawny parcel Jun 23, 2018, 9:17 AM

#

It might be tough for a system complex like that, isnt there a rule for the UE4 marketplace that your code has to work with a flat install? Just curious tbh

thin stratus Jun 23, 2018, 9:17 AM

#

It is a hardtravel to new servers

fleet sluice Jun 23, 2018, 9:17 AM

#

After all, I think UX should be the end-goal, not minizing costs. And by forcing people to hard travel between zones, you're sacrifing UX for "ease" of work.

#

Theoretically, it could work with a flat install.

bitter oriole Jun 23, 2018, 9:18 AM

#

Well if the plan is to sell a MMO kit to beginners who think they're going to have more than two players some day, sure, that might work

fleet sluice Jun 23, 2018, 9:18 AM

#

It's the synchronization part ("border") that needs to be designed in a generic and easy to use way.

thin stratus Jun 23, 2018, 9:18 AM

#

As long as you have a backend that provides you with a server instance of your level you want to play, it shouldnt matter much what ue4 does

fleet sluice Jun 23, 2018, 9:18 AM

#

I'm not thinking about beginners.

bitter oriole Jun 23, 2018, 9:18 AM

#

If you're doing an MMO, you're either not using UE4, or a beginner

thin stratus Jun 23, 2018, 9:19 AM

#

Or ue4 without the server part

bitter oriole Jun 23, 2018, 9:19 AM

#

It's okay to do assets for them too

#

Really

#

Just being honest here

tawny parcel Jun 23, 2018, 9:19 AM

#

Not sure if its possible to edit the source code to have multiple connections open at once?

fleet sluice Jun 23, 2018, 9:19 AM

#

I'm currently only doing MP products, that I may one day use myself.

thin stratus Jun 23, 2018, 9:19 AM

#

The thing is, MMO with instances on ue4 servers is more pain than anything else

#

It is a lot easier to forget about the ue4 servers and grap something like smartfox and tie that into ue4

fleet sluice Jun 23, 2018, 9:20 AM

#

But if I'm going to work on something, I'd either strive for a breakthrough or not work on it at all. I don't need to work on average since I can find and buy average.

#

I read about SpatialOS, but some things weren't good about it.

#

I'm definitely trying that soon either way.

thin stratus Jun 23, 2018, 9:21 AM

#

Big mmos run their own solutions

#

So you are usually targeting small Studios that cant afford that

#

Or dont want to

fleet sluice Jun 23, 2018, 9:21 AM

#

Yea, that's the "hard-to-guess" aspect of the Marketplace.

thin stratus Jun 23, 2018, 9:21 AM

#

And then you get to smartfox, raknet, spatialos etx

tawny parcel Jun 23, 2018, 9:21 AM

#

Even a simple MMO product that is high quality and utilizes zoning would still be a good product people would go for

fleet sluice Jun 23, 2018, 9:21 AM

#

I have to brb.

thin stratus Jun 23, 2018, 9:22 AM

#

Also, lets say you manage to get the travel working

bitter oriole Jun 23, 2018, 9:22 AM

#

IMHO the main issue is that real MMOs (those who actually have players) have their own engine. Anyone who's looking at marketplace items doesn't have the financial means to get players on the game.

thin stratus Jun 23, 2018, 9:22 AM

#

Through a plugin

#

You need something to boot up the servers

#

There is no way to sell an mmo all in one solution

tawny parcel Jun 23, 2018, 9:23 AM

#

The other elephant in the room is... would it be worthwhile doing an MMO system in the current state of game genres? They are more small niche competitive maps popping up all over.

thin stratus Jun 23, 2018, 9:23 AM

#

You can make plugins to expose smartfox, etc. To blueprints and cpp

#

So you dont have to fight with their api

#

But anything more might be a waste of time, like @tawny parcel says

bitter oriole Jun 23, 2018, 9:24 AM

#

Yeah, "MMO lite" like Destiny does is definitely something that players are fine with

#

Basically regular MP with matchmaking

#

Except the "matches" can be simple exploration on levels

thin stratus Jun 23, 2018, 9:25 AM

#

It is all very specific

#

To make a marketplace asset for

bitter oriole Jun 23, 2018, 9:25 AM

#

UE4 gives you that out of the box and you don't need anything else - and it scales very much better

#

Easy to setup for 4 online players (what most people here, including me, will ever see)

#

Still working for 4000 (if you've got the servers behind that)

umbral adder Jun 23, 2018, 9:28 AM

#

how would i go about making a online store like in fortnite

#

and do u connect to the forntie server when u launch battle royale?

bitter oriole Jun 23, 2018, 9:29 AM

#

You need to have a player account system where your players log in to the game, have a database on your servers with their character data

#

You put a shop in the game and do transactions on the database server, through the game server to avoid hacking

#

When loading a game the server connects to the database server to get your stuff

umbral adder Jun 23, 2018, 9:33 AM

#

ok

#

now what is the best way to load the players unlocked items

#

meaning i have a shop widget which shows items the are locked

#

like should i make the item's unlocked an array?

#

i have a working login system with my database

bitter oriole Jun 23, 2018, 9:35 AM

#

Well, your game would have a local list of stuff that is available in the game. The database server doesn't really need to know about the items, just which items you've bought

#

On login you get the list of stuff you've bought and you're good

umbral adder Jun 23, 2018, 9:36 AM

#

yes @bitter oriole how would i store that an int? or what?

bitter oriole Jun 23, 2018, 9:37 AM

#

FGuid works well for identifiers

umbral adder Jun 23, 2018, 9:38 AM

#

but thats only for the player right?

#

i dont think u understand what i am saying

#

in the database how would i store each players unlocked/bought items

bitter oriole Jun 23, 2018, 9:38 AM

#

List of FGuid that the player bought

umbral adder Jun 23, 2018, 9:39 AM

#

u mean array

#

guid is only in ue4 right? not php

bitter oriole Jun 23, 2018, 9:40 AM

#

YOu'd store the FGuid as a string

tawny parcel Jun 23, 2018, 9:40 AM

thin stratus Jun 23, 2018, 11:18 AM

#

Yes

#

@tawny parcel Depends, do late joiners need to know about the beam?

#

If it is a fire and forget sfx, simply multicast

twin juniper Jun 23, 2018, 1:36 PM

@bitter oriole Sorry for the late reply. That seems an interesting solution. That would probably set the other one to SimulatedProxy, right?
Also, if I change the base class to GameMode, it could fix it too?

bitter oriole Jun 23, 2018, 1:37 PM

#

Dunno, I don't use game mode

hollow patrol Jun 23, 2018, 1:37 PM

@umbral adder Yea, tried checking with some other tools, says the ports are closed - been looking into that

i took almost half a year figuring it out of course i have improved since then

proper olive Jun 23, 2018, 3:19 PM

#

Still having difficulty disabling a blocking volume on server only... since the blocking volume is placed in the map, it seems to exist on both server and client and they're interfering with each other

#

does this mean I have to spawn it at runtime like around beginplay on a client RPC?

#

client-only isn't even working in this case as the server's volume is blocking it... when the server disables it, client can still walk through it tho choppily and it's triggering overlaps

thin stratus Jun 23, 2018, 3:22 PM

#

What is your goal?`

#

If you want to replicate the disabling act, you have to mark the actor replicated and do it via a Multicast

#

@proper olive

proper olive Jun 23, 2018, 3:27 PM

#

I want to not replicate it, same problem as before basically but this time it's an actor placed in the map in the editor, not something spawned at runtime

#

so only run on server, or only run on client, depending on who runs it.... problem is, there's no "replicate" checkbox on them to even enable or disable :/

#

I'm using a dispatcher to fire a Run on Client RPC on the map, with a reference to the player's controller passed through

#

when the server disables the box, everything is peachy for him, but clients who haven't disabled it can walk through choppy and triggering overlaps on the blocking volume

#

when the client disables the box, it's like nothing happened for them, and nothing happens on the server either which is correct

#

here's muh code:

#

📎 unknown.png

#

now from my experience the other day, I think I could get away with spawning these blocking volumes at run-time on client-only, but I'd like to be able to know I can do this with volumes in the level itself without having to program every single blocking volume to spawn at runtime :/

#

of course, if that's the only way to have an object on client-only, then I guess that's what I gotta do, but this seems like it should be a common enough thing, right? is that how it goes?

thin stratus Jun 23, 2018, 3:47 PM

#

OwningClient doesn't exist on preplaced actors

#

Cause no one is owning them

#

Well the Server is

proper olive Jun 23, 2018, 3:47 PM

#

right

#

so it's gonna be a server-side actor no matter what if placed in the level?

thin stratus Jun 23, 2018, 3:47 PM

#

You can set the Owner on overlap

#

But only one at a time

proper olive Jun 23, 2018, 3:47 PM

#

oooooh

#

hmm

thin stratus Jun 23, 2018, 3:47 PM

#

And needs to happen on the Server

proper olive Jun 23, 2018, 3:47 PM

#

but it would only be one instance of it right

#

so if the client disabled it, it would still disable for all?

thin stratus Jun 23, 2018, 3:48 PM

#

No, it counts for the replicated actor

proper olive Jun 23, 2018, 3:48 PM

#

only one what at a time?

thin stratus Jun 23, 2018, 3:49 PM

#

Owner

#

A repl actor can have one owner at a time

proper olive Jun 23, 2018, 3:50 PM

#

if there are 3 players, 1 exit, with a blocking volume placed in level and a trigger back at the beginning of the hallway..... when a player runs into the blocking volume, it tells them to go back to the trigger (basically a way to prevent players from passing without checking out this cool thing)

#

so if a client walks into the blocking volume, and I tell it to set owner, then the client walks around a while without hitting the trigger, and another client comes over and bumps into the blocking volume, will that still hold up for both of them?

#

the trigger disables the blocking volume

#

sorry there's also a trigger on top of the blocking volume that I'm enabling/disabling as well, to send a message to the player, same behavior

thin stratus Jun 23, 2018, 3:55 PM

#

As said, owner can be one person at a time

#

Not two

#

Not three

#

One

#

If you need to filter them, set the response to the blocking volume to IGNORE on the player itself

proper olive Jun 23, 2018, 3:57 PM

#

you can ignore specific players?

#

and that's what I thought you meant above, hence the clarification

#

there's only one instance of the blocking volume when placed in the map is the probloem

#

but I want one client-side only for each player

thin stratus Jun 23, 2018, 3:58 PM

#

No, you just give the blocking volume a specific collision object

proper olive Jun 23, 2018, 3:58 PM

#

but the ignore specific players sounds like it'd work

thin stratus Jun 23, 2018, 3:59 PM

#

And set the character that should pass it to ignore that one

#

you don't touch the blocking volume itself

proper olive Jun 23, 2018, 3:59 PM

#

would have to do a custom collision object for each type of blocking volume then yea?

thin stratus Jun 23, 2018, 3:59 PM

#

Setting the char to ignore needs to happen with a multicast

#

Well yeah

proper olive Jun 23, 2018, 3:59 PM

#

hmm

#

sounding like spawning at runtime is the best way to go :[

#

you're the man tho, any other ideas?

thin stratus Jun 23, 2018, 4:00 PM

#

What does spawning at runtime do here though

#

You need to block the player on Server, Owning Client and other clients

#

Otherwise he will run through it on at least one instance

proper olive Jun 23, 2018, 4:00 PM

#

I would do it on beginplay, client only, is owning player, so a separate copy exists on each client's computer

#

then that way it's exclusive to each player

thin stratus Jun 23, 2018, 4:00 PM

#

That doesn't work

proper olive Jun 23, 2018, 4:00 PM

#

oh

thin stratus Jun 23, 2018, 4:00 PM

#

The Blocking volume would exist x times on the Server

#

He still wouldn't let playerA through playerB's volume

proper olive Jun 23, 2018, 4:02 PM

#

if I spawned something on client only, it wouldn't exist on the server

thin stratus Jun 23, 2018, 4:03 PM

#

Yeah and then?

#

The server would just let him run through the thing

proper olive Jun 23, 2018, 4:03 PM

#

right

#

that's the problem

thin stratus Jun 23, 2018, 4:03 PM

#

So

#

ObjectCollision Type

#

Best solution

proper olive Jun 23, 2018, 4:03 PM

#

isn't there a limit or nah?

thin stratus Jun 23, 2018, 4:04 PM

#

There is

#

But you don't have so many volumes needed at a time or?

proper olive Jun 23, 2018, 4:04 PM

#

nah just thinking if I used it as a system

#

generally speaking tho, blocking volumes are bad design yaknow, so I'm thinking I'll just figure a way to keep the door itself locked for each client

#

I'll figure it out but basically gonna ditch the whole thing 😂

#

that really helped explain it tho, one more process of the whole thing understood ☑

#

easy enough to set a variable on player state and not allow door opening until it's done

Where is character movement replication done when the server updates positions of players that the client isn't controlling?

#

CharacterMovementComponent only seems to deal with the controlling client

Unless I'm just missing it.

Because I'm having an issue where I'm seeing other players meshes decouple from their capsule components.

thin stratus Jun 23, 2018, 5:10 PM

cyan bane Jun 23, 2018, 5:14 PM

@thin stratus I know regular actors replicate in the Actor class, but Characters must do something interesting with replication elsewhere, so that it can deal with animations and I assume cause my issue as well.

uncut pivot Jun 23, 2018, 8:56 PM

#

yikes

#

so i have this actor that destroys itself and goes back to its origin when it gets too far away

distant wave Jun 23, 2018, 8:58 PM

#

explain

#

can u show me a screenshot

#

of the code

uncut pivot Jun 23, 2018, 8:59 PM

#

lol

#

its a lot of code

#

i have an item spawn class

#

to handle spawning 1000's of items

#

we spawn them locally and give them this id

#

when someone picks them up we destroy the local client item then spawn in a "real" item on the server

#

we let others know that item has been picked up by a fast array in the gamestate

#

when that gets replicated we just destroy the client items on all other clients

#

that works perfectly

#

kinda janky

#

but until 4.20

#

not much we can do

#

the real issue is

#

when i take that real item

#

and drop it somewhere

#

it destroys itself

#

and spawns back at the item spawn

#

but heres the thing its a real replicated actor

distant wave Jun 23, 2018, 9:02 PM

#

there must be a problem with the spawn code

#

the spawn transform probally

#

Also

#

on short, you destroy the local actor and u expect that the real actor will spawn at the local actor’s transform?

uncut pivot Jun 23, 2018, 9:03 PM

#

the actor is being destroyed on UActorChannel::CleanUp

#

well no

#

we destroy it

#

and it gets picked up and put in someones inventory

distant wave Jun 23, 2018, 9:04 PM

#

ah...

#

shouldn’t you kinda pick it up and then destroy it?

#

that’s what I would do

#

with a little delay

uncut pivot Jun 23, 2018, 9:05 PM

#

welp

#

the inventory is replicated

#

so i need the replicated one

#

so we just destroy it and add it

#

that works perfectly fine

distant wave Jun 23, 2018, 9:06 PM

#

okay, I can’t think of anything right now, probally if someone else will wanna help u they will ask for the project which I doubt you will give them 😂

uncut pivot Jun 23, 2018, 9:06 PM

#

lol yeah

#

its a professional project

#

not a personal project

distant wave Jun 23, 2018, 9:07 PM

distant wave Jun 23, 2018, 9:07 PM

#

will u use dedicated server or listen?

uncut pivot Jun 23, 2018, 9:07 PM

#

dedicated server

distant wave Jun 23, 2018, 9:08 PM

#

and can u tell me what ports you will port forward

#

cuz I kinda forgot the ports

uncut pivot Jun 23, 2018, 9:08 PM

#

fuck man idk

#

the standard ue4 ports

#

we have a company that does all our server hosting

distant wave Jun 23, 2018, 9:09 PM

#

ah ok

winged badger Jun 23, 2018, 9:09 PM

#

so in all that text

#

i didn't get what is troubling you exactly

uncut pivot Jun 23, 2018, 9:10 PM

#

when we drop an item

winged badger Jun 23, 2018, 9:10 PM

#

also, client authoritative looting?

uncut pivot Jun 23, 2018, 9:11 PM

#

its owner is nullptr yada yada

#

it goes back to its origin location

#

if its so far away

winged badger Jun 23, 2018, 9:11 PM

#

so far away wouldn't be around 15000 unreal units, would it?

#

i suggest you tick AlwaysRelevant on the items (just to make sure if NetRelevancy is the culprit)

uncut pivot Jun 23, 2018, 9:13 PM

#

maybe like 500 unreal units

winged badger Jun 23, 2018, 9:13 PM

#

and test it like that

uncut pivot Jun 23, 2018, 9:13 PM

#

i mean

#

why would net relevancy look at its original location?

#

welp

#

actually i can see that

#

oof yeah i think i got it

winged badger Jun 23, 2018, 9:14 PM

#

it wouldn't replicate the new Transform

#

if not NetRelevant

uncut pivot Jun 23, 2018, 9:14 PM

#

yeah because we're just attaching on client

#

so when the item moves far away

#

the server is gonna be like youre dumb

winged badger Jun 23, 2018, 9:15 PM

#

then it uses Owner's Transform instead, until you detach

uncut pivot Jun 23, 2018, 9:15 PM

#

well it only goes back when detached

winged badger Jun 23, 2018, 9:16 PM

#

just curious if client tells the server what it needs to spawn because it was looted on the client

#

what's stopping someone to hack your game and trick the server into spawning whatever he/she wants?

uncut pivot Jun 23, 2018, 9:16 PM

#

you dont tell the server what you want to spawn

#

its kinda weird

winged badger Jun 23, 2018, 9:17 PM

#

no, but you tell it the ID of an item you picked up

#

and that can be hacked

uncut pivot Jun 23, 2018, 9:17 PM

#

that still isnt how it works

#

the item spawner can only spawn what its supposed to

#

which essentially means you cant be like AItemSpawn->Spawn(ABestGun::StaticClass());

#

you just tell the item spawn to spawn its item

#

now there is definitely some things that are very non hacker proof

Hello guys I have a problem and need help. I'm trying to make a dedicated server for my game on steam and I've watched and followed this tutorial https://www.youtube.com/watch?v=iMNjp5L7_oA . Everything worked well until at final phase, when he checked if the server he opened was on Steam, my server wasn't on LAN or internet , while his was. The ports are 100% opened as I've checked it and so I suspect that the server doesn't listen for incoming clients. Can someone help me find a solution for this problem ?

gusty spire Jun 23, 2018, 10:03 PM

Ok so I've compared my logs to the ones of the guy in the video and it seems like my server doesn't execute some final lines that are being executed in the guy's video: https://i.imgur.com/54hVbDd.png (this is my cmd) ; https://i.imgur.com/TJEEX0m.png (his cmd). Apparently my server doesn't listen as I had suspected + his server does some things with SteamNetDriver_1 and his SteamNetDriver_0 shuts down, while my SteamNetDriver_0 doesn't.

What can I do about it?

meager spade Jun 23, 2018, 10:13 PM

@cyan bane what you mean non-owner client replication?

#

all replication must have an owning controller

cyan bane Jun 23, 2018, 10:14 PM

#

Sorry, by non-owning i mean controlling

meager spade Jun 23, 2018, 10:14 PM

as far as i know anyway

cyan bane Jun 23, 2018, 10:15 PM

I'm trying to find where characters you don't control replicate

as in other players

meager spade Jun 23, 2018, 10:15 PM

#

NPC are owned by the server, other players you don't control the server sends the details of them clients to you

cyan bane Jun 23, 2018, 10:16 PM

#

Yeah, but where?

#

As far as i can tell your characters movement replicates in CharacterMovementComponent, but not other players you see

When I set an event as multicast, will it be ran in all the player including the "fake" ones in the server? or only on real players?

magic helm Jun 23, 2018, 11:21 PM

#

It runs on all instances including the no player controlled versions, if you wanna filter for only player controlled versions then use the function Is locally controlled, as a check

glacial lotus Jun 23, 2018, 11:26 PM

Is possible to reach the player character from the player state?

@crimson notch probably need to turn off adaptive update rate on property replication if it is on

crimson notch Jun 23, 2018, 11:35 PM

#

i think i should store variables that are needed to be seen by all players in the player controller, instead of the player state?

distant talon Jun 23, 2018, 11:36 PM

#

the player state is fully replicated and should replicate to all clients (unlike the game mode)

#

er wait

#

Yeah, the player state is in the game state

crimson notch Jun 23, 2018, 11:37 PM

#

im telling the server to update every player state, but it only updates the server one for some reason 😦

winged badger Jun 23, 2018, 11:58 PM

#

there is plenty wrong with that

#

you don't need custom logic to get controllers from GameMode (GetGameMode->GetNumPlayers->For(0 to NumPlayers-1)->GetPlayerController(index)

#

you don't need to send a ServerRPC from a ServerRPC, execution is already on Server

#

as for why it doesn't work, you haven't shown the relevant part @crimson notch

#

for variables in PlayerState to propagate, each of them has to be set to replicate, for example

#

i strongly suggest reading thru Cedric's Compendium (its pinned on this channel)

crimson notch Jun 24, 2018, 12:01 AM

#

i thought that too zlo, but i have two other variables that work without replicate, i got it to work anyway, i replicated the variable i needed 😃

#

i think the reason my variables worked before without replicating, is that i had them incrementing each time the event was called, but thanks for the information, il use it next time!

How to get the player controller having the Player ID(from the Player State->Get Player ID)?

umbral adder Jun 24, 2018, 2:36 AM

#

@gusty spire if the cmd doesnt ask u for firewall access the first time u open it, it means you havent setup the steam part properly

#

also do a log verbose

#

u SHOULD NOT have any warnings or errors

#

even if it doesnt seem steam related

#

i have a lot of trouble doing this the first 3-4 times

#

but then i got it

#

anyways here are the ports i am using

#

#

also check if u have allowed the firewall access or even temporarily disable it.

also test if ur port are open with this small testing tool I made

it is for port 25565

i am looking at GCP vs Azure vs AWS

twin juniper Jun 24, 2018, 4:02 AM

@umbral adder mine is free currently, t2.micro instances under 750h and 30 gb-mo use. just gotta make sure to use the project launcher to create your ded server isntances so the ram use isn't too high. my ram was really high at 4 gb but when i built the ded server from the project launcher it greatly reduced ram util

umbral adder Jun 24, 2018, 4:02 AM

#

ohh aws?

#

so is it good?

twin juniper Jun 24, 2018, 4:03 AM

#

the bandwidth is good yep.

umbral adder Jun 24, 2018, 4:03 AM

can it handle 10players? and after usage is it gonna be cheap

twin juniper Jun 24, 2018, 4:03 AM

only tested with 3 max so far

#

in a same game

#

they connected properly

umbral adder Jun 24, 2018, 4:03 AM

#

would u recommend Google cloud or aws?

twin juniper Jun 24, 2018, 4:04 AM

#

i can only speak from experience, i say t2 is good. but you gotta make sure to select free teir in settings when you start the instance.

umbral adder Jun 24, 2018, 4:04 AM

#

ok

#

what is the difference between ec2 and t2?

twin juniper Jun 24, 2018, 4:05 AM

#

📎 unknown.png

#

that one

#

is best

#

t2 is a subset of EC2

umbral adder Jun 24, 2018, 4:05 AM

#

ok

twin juniper Jun 24, 2018, 4:07 AM

#

📎 unknown.png

#

@umbral adder that is a guide i made with my friend jtxp. should help you. you wanna make sure to open the ports in the instance once you create it.

#

and keep in mind it's free.. so you really have nothing to lose. you can just start it up.

#

create an account and launch the instance thru the ec2 dashboard

#

you also gotta use remote dekstop to connect to it, and create a key pair to login (first) before you makea password as admin which you login with later.

#

once you got it setup you just disable the firewall and windows defender and stuff like that on the instance so the ram use is lowerered, to make way for the ram your game will take up. keep in mind 1 gb is max ram so you really need to optimize everything.

#

and do not forget to install the ue prereqs .. i forgot that for a bit.

umbral adder Jun 24, 2018, 5:18 AM

glacial lotus Jun 24, 2018, 7:29 AM

Is a bad idea to send a Player State to a "Run on SERVER" event? What does it really send? An int? a pointer? a blob with the whole thing?

sharp pagoda Jun 24, 2018, 7:31 AM

#

Sending object references over the network is quite a bit more complex than a simple pointer. If you think about it, how would another computer receive a pointer to a location in memory on machine A? It would be garbage. So instead, sending a reference over the network is resolved in the low level net handler to refer to something like an object UUID which can then be resolved on the receiving machine, mapped to a pointer in the new client's memory, then manipulated there. @glacial lotus

@sharp pagoda ok, I understand. So this uuid is small enough to still be a good idea? Or should I try something else?

sharp pagoda Jun 24, 2018, 7:34 AM

Yes it's a fairly lightweight procedure to refer to actors over the network

glacial lotus Jun 24, 2018, 7:35 AM

great 😃

sharp pagoda Jun 24, 2018, 7:35 AM

I would guess it's 64 bits per reference, don't quote me on that though

@umbral adder take a look at OVH for cheap and reliable servers.

thanks but already got into AWS

marble depot Jun 24, 2018, 9:17 AM

that's a great option too, only thing would be you have to manually set up your anti ddos bullshit protection because aws doesn't have great protection by default

the ones in the server

winged badger Jun 24, 2018, 9:47 AM

all player controllers on the server belong to players

except instead of dropping you attach it to character somewhere

Hello, I wondered if there are some people willing to share a server project. I mean a special server project. Some thing like a cloud/master server. If 50 players are waiting for example for joining a server, that the master server starts up a gaming server

#

Sry for bad explanation

thin stratus Jun 24, 2018, 2:34 PM

You mean a Service that launches Servers on demand and closes them again, like GameLift.

i have an instance running on ec2 but how do i know what is my ip so that i can connect to itue4

umbral adder Jun 24, 2018, 4:14 PM

i cant connect to my public ip in aws

#

i have no server errors

#

or warnings

#

i have added outbound all traffic rules and inbound to all tcp and udp

umbral adder Jun 24, 2018, 4:58 PM

#

ANY IDEAS?

thin stratus Jun 24, 2018, 6:02 PM

#

Each instance shows their ip in the list of instances

#

@unreal adder Well, that is really not something we can answer :P

#

You will simply notice when it is too big

#

And then you have to optimize it

#

For meshes, i would maybe already optimize with some LODs

#

Later you can also devide the world with streaming levels

#

Really depends on the level of Detail you are going for

unreal adder Jun 24, 2018, 6:06 PM

#

Hm
Do you start to get packet loss or bad latency when it becomes too expansive?
Yeah, LOD is a given

Hi, I have a Idea of Multiplayer that is based on "Listen-Server" but when on a Listen Server the host leaves normaly the game for example would end wich can be realy punishing for everybody else if the Person has to go or even Rage Quiets. So this is an Idea maybe im on a completly wrong direction and there is already something to fix that and so im asking here if this could be a solution.

#

📎 konzeptidea.png

#

ok we can all agree im crazy im fine with that

glacial lotus Jun 24, 2018, 9:01 PM

#

I'm interested @hot robin Can you explain the graph? And are you trying to do "host migration"?

hot robin Jun 24, 2018, 9:02 PM

#

kind of

glacial lotus Jun 24, 2018, 9:03 PM

#

so your idea is everybody is a listen server, disabled by default except the real host. If this guy leaves then the next one in the list will be the host. Right?

hot robin Jun 24, 2018, 9:05 PM

#

because i want to make a Multi Player game but i cant start without choosing between listen vs dedicated there are pros and cons like dedicated being able to operate ob more people better with maybe even a better connection but also server cost and the risk of ddos and all these things listen server however would be depending on the people and all players but with a "Standard" Ue4 Listen Server like with Steam it would be 1 will be the host the rest have to join via Steam or a server list buuut if the host leaves the game has to stop for everyone wich kind of sucks

#

then there is the problem wich may some people expierenced with host migration in games like CoD that it was kind of "anoying" if the game started to search for a new host "mid game"

fleet sluice Jun 24, 2018, 9:11 PM

#

You can't achieve that with a standard UE4 build. There is a concept of "ownership" which dictates the replication flow from server to all clients. What you need is to transfer that ownership to a new client, which will become the next server. You need heavy C++ for that and there isn't a single example of a successful implementation on the web.

#

A much better bet would be to not use any sort of "real" UE4 servers and instead use a networking library (low-level sockets stuff; i.e. Steam's networking interface https://partner.steamgames.com/doc/features/multiplayer/networking ) to sync the properties you need to sync between the actors that need to be synced.

#

At least that way you won't have to worry about running into hard-coded engine stuff. In this context, a lot of the networking code will seem "hard-coded" because it was never designed for host migration. It was based exclusively on a client-server architecture.

hot robin Jun 24, 2018, 10:18 PM

#

This API works best when used with Steam Matchmaking & Lobbies, depending on the types of packets you could route everything through one player that is acting as the host (typically the lobby owner) or game server, or send everything out directly to each player.

twin juniper Jun 24, 2018, 10:19 PM

#

@hot robin dedicated is the way to go. it's basically easier for players to join in on a massive server, and players that lag that create listen servers always bog down the connection for everyone. if you're serious about your game, and have some capital saved, you can easily afford dedicated. plus there are some free annual options for dedicated hosting out there. just look at any good example out there. swbf2 has dedicated and the game is pretty cool.

#

and yeah for listen servers , the host leaves, everyone gets disced, as you said.

hot robin Jun 24, 2018, 10:21 PM

#

if i go with dedicated i have to use the c++ from the github and can i go with the normal way of blue print replication with dedicated?

twin juniper Jun 24, 2018, 10:21 PM

#

you have to sourcebuild, yes.

#

and in visual studio, you have to run a development editor and development server build, although you can use the unreal engine project launcher to build the server binary which is much better since it lowers RAM.

#

want a guide i wrote on the subject? i can DM it to you.

#

its like 3 pages long. details every step.

hot robin Jun 24, 2018, 10:22 PM

#

sure sounds good its always better to follow a written tutorial instead of a video like youtube wich often is either to fast to slow or has noise or music in it

twin juniper Jun 24, 2018, 10:23 PM

#

and by the way you are really better off using CPP in your game anyway.. i added cPP to late in mine. my game has very minor netlag in my dedicated server builds. simpoly because i added cpp too late 😦 95% blueprint code right now.

#

migrating as much as i can to CPP as we speak. all right ill DM it.

hot robin Jun 24, 2018, 10:24 PM

#

i have a bit of a problem with cpp tho

twin juniper Jun 24, 2018, 10:24 PM

#

as in knowledge of it?

#

udemy cpp tutorials then. best there is

#

the unreal syntax is a bit confusing. those tuts help a lot.

#

look for "udemy cpp unreal" on google and look for ben's stuff.

#

im actually in the process of going thru the tut now - and i can assure you it's really well done. really informative and thorough.

hot robin Jun 24, 2018, 10:26 PM

#

i can read the code and can kind of see what it is doing but i can write it i know what a bool is i know integer , floats , loops , string and stuff like that but its pretty basic

#

oh i have the udemy course of the 2 british guys right

twin juniper Jun 24, 2018, 10:26 PM

#

yep. one with ben and the other assistant guy.

hot robin Jun 24, 2018, 10:26 PM

#

yeah i got it for 10€ or something on a super discount

twin juniper Jun 24, 2018, 10:27 PM

#

they always have that discount lol

#

its still on right now

#

😛

#

its sort of a ploy really.

#

but tahts okay, the content is good lol

hot robin Jun 24, 2018, 10:27 PM

#

but for all the "HOURS" of material its totaly worth it

#

they start pretty simple on the bull and cow game then go on and waaaaaay later its about UE4

#

but im aware of the BP vs C++ thing

dull stream Jun 24, 2018, 10:29 PM

#

I want to make sure I understand something.. on the client's machine, if i see another player character, that character has the role simulated_proxy right? and I would have autonomous proxy?

#

on the server, the role would be Authority for all player characters, and remote role would be autonomous proxy?

#

is this correct?

#

I must have some misunderstanding, I thought that was the case but perhaps not

If I get that right you set the role and remote role on the server, if the role is Authority and the remote role simulated proxy then all clients will be simulated proxy. Unless you specify on a client that it's role is autonomous proxy it will have the simulated by default because the server said so?

#

from what i understand, you dont set the role at all, its just a matter of does your controller own this and you control it... if so, then its autonomous. If its some other players character, and the server is dictating how it moves, then its simulated

vocal dagger Jun 24, 2018, 10:52 PM

#

that actually makes sense

#

but I think you can set that on the server

dull stream Jun 24, 2018, 10:52 PM

#

that might be true, Im not sure. still learning.

vocal dagger Jun 24, 2018, 10:53 PM

#

yeah, I haven't gotten to test that part yet

dull stream Jun 24, 2018, 10:56 PM

#

what i dont get is that in my tick, im printing things out depending on if its simulated or autonomous... and only autonomous prints out. and not only that, but its also printing out the info from the other client it seems? I have no idea, its weird. what makes it stranger is that it seems to be behaving correctly aside from that

#

I damage the player and when they get damaged enough, they cant shoot. this behavior seems to be working correctly. but when i print the health of the players, its like they are both getting damaged rofl

#

I'll look more into it

#

how are you getting the info from the other clients?

#

you should be doing that using the player states right?

#

and the game state should have those in an array

dull stream Jun 24, 2018, 10:59 PM

#

the way im getting the info from the other clients is that im expecting the simulated proxy character to tick, and during tick it prints out a statement. but maybe its incorrect to assume its ticking

#

the info should be updated because the server does a multicast

vocal dagger Jun 24, 2018, 10:59 PM

#

but you cannot get info from other clients like that unless you are the server (I guess)

dull stream Jun 24, 2018, 10:59 PM

#

hmm

#

that makes it difficult if you want to display another players health

#

i guess i would have to request it from the server

#

that makes sense though because it would be a security risk to allow you to just look at anyones data

vocal dagger Jun 24, 2018, 11:04 PM

#

oh but wait, you could get the replicated info on the pawn from the server

#

I was checking it out from Cedric's guide http://cedric-neukirchen.net/Downloads/Compendium/UE4_Network_Compendium_by_Cedric_eXi_Neukirchen_BW.pdf

dull stream Jun 24, 2018, 11:06 PM

#

Im super confused rofl. Its behaving in such a weird way.

#

its definitely printing the health values from both characters on my screen, despite having an AutonomousProxy check

#

could this be an editor bug?

#

like its printing debug statements on screen from both clients

#

because that would explain it I suppose, and also explain why functionally it seems to be behaving correctly

#

yup, thats the case. so strange. I would have expected this to behave differently

#

like each window gets its own on screen debug messages

#

but its shared

For a third person game with aiming, since the server doesn't know your camera rotation, when a player fires, what convention is normal for the server understanding the proper fire location/rotation?

#

do clients normally send aim info to the server?
