you could try moving it in tick

yeah you're right

#

it's too early -_-

#

yeah i put in a delay 1s and it worked

#

thanks for the help

#

@scenic raven appreciate it

scenic raven Apr 11, 2019, 5:07 PM

#

no worries, happy to help

#

@timid pendant how are you trying to replicate it

#

from a quick look

#

I think you are trying to change playername

#

also from the other clients

#

PlayerState is replicated

#

so that code is being run everywhere

#

(that's just a quick look I'm afraid)

timid pendant Apr 11, 2019, 5:13 PM

#

Im having it run from the playercontroller

scenic raven Apr 11, 2019, 5:14 PM

#

ABasePlayerState is a player controller?

timid pendant Apr 11, 2019, 5:14 PM

#

But sometimes it does work and other times it doesnt

#

I call the playerstate function from playercontroller

scenic raven Apr 11, 2019, 5:16 PM

#

I am sorry I need to go now can't help you further. I would try and see if the error is random or it happens under specific conditions

Please can you explain what is the boolean variable "Absolute" on the OpenLevel node ?
documentation : "if true options are reset, if false options are carried over from current level"
Don't understand

thin stratus Apr 11, 2019, 5:41 PM

#

@scenic raven Your issue in the video is not a bug.

#

It's the time it takes for the client to spawn the Pawn after joining.

#

The Camera sits at 0,0,0 where the PlayerController sits

#

Until the Pawn is spawned and possessed

scenic raven Apr 11, 2019, 5:42 PM

#

thx but it's not completely correct. You can see the back of the player character there

#

that character is a secondary pawn that is spawned by the playercontroller after the main pawn is ready

#

and in the scene there is an extra cameraactor that I am not creating

#

that remains there after switching cameras

#

it's puzzling for me but I hope it's obvious for someone else 😃

thin stratus Apr 11, 2019, 5:43 PM

#

Well, are you sure the location you are at teh start

#

when seeing teh character

#

is not 0,0,0?

#

Jesus, I hit the e key faster than the h key

scenic raven Apr 11, 2019, 5:44 PM

#

I can tell you cause the camera is still there just a sec

thin stratus Apr 11, 2019, 5:44 PM

#

I don't get what that has to do with it?

#

It can totally be that the Possession part of the Pawn also takes a bit

scenic raven Apr 11, 2019, 5:45 PM

#

you are correct

#

but what you see is not a pawn

#

I mean it's not DefaultPawn

#

DefaultPawn is a movable camera

#

that pawn you see there is spawned by player controller, after the movable camera has been possessed

#

I don't know if I'm making sense 😃

#

this is my scene before I hit play

📎 unknown.png

#

this is after

📎 unknown.png

#

BP_MovableCamera is my camera

#

CameraActor1 is spawned by someone

#

and I don't know who 😃

#

CameraActor1 is the one looking there

#

at the beginning of the game

#

(CameraActor and CameraActor1 are there because of Client/Server)

thin stratus Apr 11, 2019, 7:49 PM

#

My goodness, PlayFabs stuff is even worse than GameSparks

#

Why on earth would you return Statistics as a simple JsonObject array

#

How the f*ck should I know which element has my XP, my Level etc. without looping over the array and checking the StatisticName of each JsonObject

#

Who designs stuff like that

#

It would be so easy to put each statistic object behind its name

#

;-; i hate these third party sdks

bitter oriole Apr 11, 2019, 7:51 PM

#

Do your own !

thin stratus Apr 11, 2019, 7:51 PM

#

I would, but not time.

#

Also not the resources for the backend.

#

But damn, you would think Microsoft would do this properly.

#

Also, all their Client API pages are 404.

#

And the documentation on stuff like "GetPlayerProfile" and "GetUserAccountInfo" says the exact same thing, so you have no idea what either does.

#

(╯°□°）╯︵ ┻━┻

#

Turns out, I need to get PlayerStatistics and PlayerInventory. What does PlayerProfile even do, return the username alone?

#

Uff, I swear one day I get a heartattack cause of stuff like that

#

I will just get the values in the same order I requested them

#

¯_(ツ)_/¯

#

Ah yeah and in the request needs you to enter the names of the statistics in a comma list

#

stat1,stat2

#

And directly below that they use an array

#

Why not just make an FString Array

chrome bay Apr 11, 2019, 8:00 PM

#

All I can say is, hurry tf up EOS

thin stratus Apr 11, 2019, 8:00 PM

#

Stop putting people on plugins for ue4 that have no idea aobut ue4

#

GameSparks had a fucking sceneComponent for their connection class

#

Until I told them to make it at least an object ffs

#

And yes, EOS should really hurry up

#

As soon as that fully releases

#

I will see how I can move all users over to EOS

#

And didge all the rest

chrome bay Apr 11, 2019, 8:02 PM

#

Yeah. I mean they've got the backend up it looks like, just not much else. Waiting for Epic to inevitably release a plugin that interfaces with it all

#

Kind of weird that they haven't yet but i guess it's too early still

thin stratus Apr 11, 2019, 8:04 PM

#

Well you can see the API already

#

Just not with everything

#

I wanted to try out the Ticket System they offer

#

Cause that is already available

#

@chrome bay Did you ever release you code or a blog post or so for your radar?

#

I wonder if you can pull of something like this with that:

pallid mesa Apr 11, 2019, 9:04 PM

#

It's based on SMeshWidget

#

and apparently it's complicated to use =/

#

But maybe if you dig enough that class you can pull something out without waiting too much for James

Yeah, I'm fine with waiting for now

#

Thanks for the thread. Will bookmark it!

glacial pollen Apr 12, 2019, 2:47 AM

#

I have my collision capsule "OnLanded" with my attached static meshes when falling....

#

This only happens when falling for more than say, 10 seconds

#

its like one part lags over time, until it "thinks" it landed on its OWN ATTACHED mesh....

#

Any ideas?

#

(if I manually, reduce speed every 5 seconds or so, this doesn't happen)

#

I should point out this is for a "sky diving" mechanic, and only happens when the player is facing head down

#

I assume the lag is still there, but going the opposite way, hence no lag

chrome bay Apr 12, 2019, 7:56 AM

#

@thin stratus never released the code as it's pretty unique for my project. but yeah in theory that radar could be done with it

flint plaza Apr 12, 2019, 7:56 AM

#

Hi all. Is it a bad idea to put RPC functions on tick?

chrome bay Apr 12, 2019, 7:56 AM

#

generally yes

thin stratus Apr 12, 2019, 7:57 AM

#

@chrome bay And what about any hints and insight on how the SMeshWidget thingy works?

#

Like what it expects in terms of data, how to format that data etc.

chrome bay Apr 12, 2019, 7:57 AM

#

Hmm the best example project is the one Nick Darnell released in that mesh widget thread

#

lemme see if I can find it

Alright, didn't know there is a test project

chrome bay Apr 12, 2019, 7:58 AM

#

I posted some info in that thread but not too much 😄

#

@flint plaza generally yes. At the very least make them unreliable and throttle them so they aren't being sent at whatever framerate someone has

thin stratus Apr 12, 2019, 7:59 AM

#

Any idea how complex the data for these widgets can be?

#

Yours is pretty "simple" in the sense of the stuff it produces

#

Like, what if I through in data to draw a sphere

chrome bay Apr 12, 2019, 8:00 AM

#

The data side of it isn't too difficult the hard part was largely working out how to give it that data

thin stratus Apr 12, 2019, 8:00 AM

#

Instant slate kill? :D

chrome bay Apr 12, 2019, 8:00 AM

#

But think of them as sprites really

#

That you can send very limited amounts of unique data too each one

#

(via UV's)

thin stratus Apr 12, 2019, 8:00 AM

#

Well they are 2D, but your radar suggests it's 3D data?

flint plaza Apr 12, 2019, 8:00 AM

#

Well I have a racing game. How else can I inform the server of the whereabouts of the client's car

#

because the car has to be moved on the server

chrome bay Apr 12, 2019, 8:00 AM

#

So the sprites are 2D but you can create them from meshes, so they are like.. projected 3d I guess

flint plaza Apr 12, 2019, 8:01 AM

#

and the input is on tick

thin stratus Apr 12, 2019, 8:01 AM

#

That's what I thought

#

You do send Input on Tick, that is correct

#

The CMC does that too

#

That and some other highly optimized data

chrome bay Apr 12, 2019, 8:01 AM

#

Yeah in that case it is sent on tick, but the data is heavily packed and multiple packets are combined together

#

outgoing RPC's are also throttled by CMC

#

in both directions

thin stratus Apr 12, 2019, 8:02 AM

#

Yus, to save bandwidth. If you need something like predictive car movement and stuff, you are deff into creating your own c++ movement comp

#

Cause just with BPs I highly doubt that's possible to even remotely maintain

flint plaza Apr 12, 2019, 8:23 AM

#

dumb question, what's CMC 😅

thin stratus Apr 12, 2019, 8:26 AM

#

Character Movement Component

#

There are a few concepts you need to apply to Movement Replication

#

Cause otherwise, with a slightly higher ping, you'll get corrections and it will be a pretty shitty experience for the client

#

That is if you are interested in Server Authoritive movement

flint plaza Apr 12, 2019, 9:03 AM

#

Is that the correct approach?

#

Also, for movement, I dont do a addActorWorldOffset

#

or similar thing for rotation

#

Instead, I apply calculated forces to a point

deep beacon Apr 12, 2019, 9:17 AM

Greetings! Is there something like a guide/documentation/wiki/forum post where I can read about connecting as client to a dedicated server with the same IP and Port, but different GameSessions, like it is the case at AWS, where several instances of your dedicated server are spawned, but only identified via AWS-related GameSessionIds. It feels like a dug through the entire internet without finding something about that besides multiple Ports, which doesn't correlate with GameLift (or I just don't get it). I read through most of the posts here about AWS and came to the point where it seems to be too expensive without proper funding, but nevertheless I got everything working so far, besides that. And I would like to at least finish that pipeline.

chrome bay Apr 12, 2019, 9:38 AM

#

Multiple ports is the only way to host multiple dedicated servers at once on the same box. You can't have two different servers communicating via the same port.

#

old thread: https://forums.unrealengine.com/development-discussion/c-gameplay-programming/22980-multiple-dedicated-servers-on-one-system

thin stratus Apr 12, 2019, 9:57 AM

#

GameLift also has multiple ports

#

You are even specifying the port range when setting up your build.

deep beacon Apr 12, 2019, 10:11 AM

#

True, and I did that, but on the Console I see the same port (7777) on each Instance. @chrome bay but thanks already for ruling that out. Still pretty new to the dedicated server business.

#

And this old forum post brought me to the question on how every server instance is supposed to know which port it would have as they aren't aware of other instances. I guess some kind of master server is needed here which creates those server instances via commands at AWS?

chrome bay Apr 12, 2019, 10:30 AM

#

You just tell UE4 which port to use for each instance IIRC

thin stratus Apr 12, 2019, 11:22 AM

#

@deep beacon That should only be the case if you only launch one DediServer per instance.

#

UE4 autoincrements the port afaik

upbeat basin Apr 12, 2019, 11:28 AM

#

Hey eXi, I would like to thank you for your responses on my previous question, I didn't had time to say it

#

And I continue with new questions :D

My current problem is with testing. When I set number of players to 2 and try to Host a game (calling World->ServerTravel(map)) the game I clicked opens the desired map and other one goes to black screen. I don't know if the explanation is enough but basically it feels like my button click from one PIE player also triggers other PIE player

deep beacon Apr 12, 2019, 11:48 AM

#

@chrome bay My question is how, when every instance doesn't know of eachother (that's why I'm assuming a master server is needed?)
@thin stratus Is it possible that the autoincrement is stopped somehow if a port is set somewhere? (.ini, or code). The default in AWS is pretty much to start your fleet, which then creates as many server instances with as many concurrent processes as you like, but so far they always had the same port. But I will have another look into it. Thank you for the answers.

thin stratus Apr 12, 2019, 11:48 AM

#

Each Instance can be seen as a PC.

#

And each of these launches X DediServers (depending on how you set it up)

#

With incrementing ports

#

At least it should

deep beacon Apr 12, 2019, 11:50 AM

#

so there should be nothing, stopping the DediServers from having various ports beside the 'default' 7777?

worthy perch Apr 12, 2019, 11:50 AM

#

So the IP and the port are always the same?

deep beacon Apr 12, 2019, 11:51 AM

#

seems like it yes. I have no screenshot at hand, but once I get back to it on the weekend I could deliver them

#

That's why I am at my wits end, because I have no clue how to join a server without having the unique IP:Port combination (assuming this ONE connection would not be a server specialized in distributing clients somewhere else.. but this is above my paygrade)

worthy perch Apr 12, 2019, 11:53 AM

#

I'm not familiar with your problem, but the worst case is you can manually specify what port a new instance should be on.

deep beacon Apr 12, 2019, 11:57 AM

#

I considered that, but somehow I get the impression that GameLift/AWS gives you these tools already (like exi mentioned), but so far it seems, that I don't work with them appropriately

scenic raven Apr 12, 2019, 12:23 PM

#

When I have a replicated class, are all its properties replicated?

bitter oriole Apr 12, 2019, 12:23 PM

#

Nope

#

Just its existence is replicated

#

You can then set individual properties to replicated

scenic raven Apr 12, 2019, 12:23 PM

#

thx

vague veldt Apr 12, 2019, 12:34 PM

#

@chrome bay Ty for response.
I have read this documentation but it's a bit confuse for me.
I use only blueprint in my project.
I just want to be able to join server (build project01) with the client (build project02--> witch is just a duplicate of project01) or better in PIE.
what i need to change ?

scenic raven Apr 12, 2019, 12:35 PM

#

Is there some widely used pattern to wait for classes to be propagate before actually start playing?

bitter oriole Apr 12, 2019, 12:35 PM

#

Not sure what you're asking here. Client should be pretty autonomous regarding server

scenic raven Apr 12, 2019, 12:46 PM

#

I'll give you a small example, but it's wider than that at happens in different ways, hopefully I can make it clear :)

My setup is the following:

PlayerController possesses a Pawn that is a movable camera
During initialization PlayerController spawns a Character actor, possessed by an AIController. This is what the player perceives to be the "Player Character"
PlayerCharacter has a Widget component used to show player name
PlayerState holds AbilitySystem and relative AttributeSet
There are a few widgets here and there that show AttributeSet values

The first big problem is that given the importance of PlayerState I have to make sure that is replicated before doing a lot of the Player Character initialization. I solved that with something that makes me feel dirty ```cpp
void AVVPlayerController::WaitForPState()
{
AVVPlayerState *PState = GetPlayerState<AVVPlayerState>();

if (!PState)
{
    FTimerHandle UnusedHandle;
    UE_LOG(LogTemp, Warning, TEXT("Waiting for PlayerState, 1s"));
    GetWorldTimerManager().SetTimer(UnusedHandle, this, &AVVPlayerController::WaitForPState, 1.0f, false);
}
else
{
    OnPlayerStateAvailable.Broadcast(PState);
    OnNamePlateAvailable.AddDynamic(PState, &AVVPlayerState::OnNamePlateAvailable);
    AsyncBeginPlayingState();
}

}

void AVVPlayerController::BeginPlayingState()
{
Super::BeginPlayingState();
WaitForPState();
}

void AVVPlayerController::AsyncBeginPlayingState()
{
// Do stuff here
}

[continues]

#

Now I'm hitting other problems. For example, when trying to replicate the player name across all clients in order to show it in the widget component of the PlayerCharacter I have three potential errors: PlayerCharacter has not replicated yet, PlayerCharacter->WidgetComponent hasn't replicated yet, PlayerCharacter->WidgetComponent->UserWidgetObject hasn't initialized yet

#

unfortunately the timing for all of this is unpredictable

#

My thinking is I must not be the only one with problems like this, and I wonder if other people have solved it and how

bitter oriole Apr 12, 2019, 12:49 PM

#

No, there isn't some easy way. Netplay is hard.

#

The way to solve it is to be super careful, test a lot, and make your game as simple as possible

#

For complex objects you're bound to end with state machines that check what you're doing

vague veldt Apr 12, 2019, 12:54 PM

#

😕
I have exactly 2 same project : project01 and project02

i create a session in project01
i want to join this session from project02
i have an error : NetworkFailure: OutdatedClient, Error: 'The match you are trying to join is running an incompatible version of the game. Please try upgrading your game version.'

@vague veldt Source control ?

#

Also PIE does not have sessions

vague veldt Apr 12, 2019, 1:01 PM

#

no source control
all my students in my classroom have project02 (a duplicate version of mine project01)
I launch project01 in my teach pc witch create server
My students launch project02 on their pc and try to join my server
Project01 and project02 are not exactly the same due to buildID probably, so that dont work
I try that in PIE and in build project

#

is it possible to just disable the verif buildID ?

bitter oriole Apr 12, 2019, 1:02 PM

#

You need to use source control to replicate copies of the project

#

And PIE doesn't have sessions, again, so make sure you don't use them and connect by IP

vague veldt Apr 12, 2019, 1:03 PM

#

yes i connect by ip with an execute console node open IP

#

don't want to use source control, because my students make project02 themselve (it's a training), they reproduce what i do in my project01 (videoprojector)

bitter oriole Apr 12, 2019, 1:05 PM

#

Dunno then, UE4 isn't meant to work with different projects

vague veldt Apr 12, 2019, 1:09 PM

ok 😦 what value ue4 check to reject ?
that seem to be possible by overriting the networkVersion in the past : https://answers.unrealengine.com/questions/216374/android-multiplayer-outdated-version-of-the-client.html

you can override the network version by binding something to the delegate from somewhere, like this

but why are you trying to connect between projects with different names ...?

just use a "project02" yourself too

if the two projects you are trying to connect do not have exactly identical content you will experience unpredictable behavior

this is what is causing you to get NetworkFailure: OutdatedClient

#

but it's questionable what you are trying to achieve

#

if you or a student make any modification that wasn't made on the other side, you'll experience anything from missing objects to crash

#

unreal doesn't sync the content from the server when you join

fleet raven Apr 12, 2019, 1:20 PM

is there a specific reason why you want to use a different project name though?

#

with the same name, attempting to connect should work

gusty lily Apr 12, 2019, 1:42 PM

#

I am trying to get a lightning gun (quake) type lazer beam to work (cosmetic for clients other than owning character). i thought the concept was to have a simple replicated variable for the character, like beam on or off, then do some stuff. and because the character is set to 'net load on client' then other clients will detect the on/off change and do the stuff the character says to without needing set the start and end points via RPCs, because each client will do it for the character. Is that how it should work? but it doesnt seem to be. do i need to chagne the on/off state via a RPC call or would setting it to replicate be enough?

If you’re moving from a lobby with players to a new level, do you use the open level node or is there another way?

gusty lily Apr 12, 2019, 1:45 PM

#

server travel

#

instead of 'open'

#

i believe it has to be an execute console command node?

My character capsule is colliding with attached static meshes when the character is upside down falling from the sky

#

This technically shouldn't be possible no matter what I am doing....

#

but I assume we have some sort of de-sync going on....

#

but even then.... the attached part is assigned to be relative to the character....

#

If I force the fall speed to be reduced, it doesn't happen

#

visually, it appears like the character hits an invisible platform mid air, comes to a complete stop, and then continues, until the next "hit"

#

sometimes the character will "recoil" back up in the air like a bouncy ball

hello guys - i have a VR Project i'm working on where i've replicated the BP_MotionController (VR Hands) so i can pickup actors and release them and its replicated (Location/Movement).

I'm having a problem on release.... when i pickup an actor its fine - snaps to my hand in the area i want it to just fine. When I release - its sporadic as to where it is in relation to the hand.... sometimes its a inch away - sometimes a few feet!

I've gone through and debugged things - setup a trackinjg DebugSphere on tick that is on multicast.... its spot on in the center of my hand (MotionController::GetWorldLocation FYI the motioncontroller is set to bReplicates.True - wouldnt replicate without it... yes the actor is set to replicated)...... OnRelease - i'm drawing another debug sphere (IN THE SAME CLASS) of its location - same as the tick event debug sphere getter (MotionController::GetWorldLocation) This event is almost never near my hand's location - or that of the tick event...... How can this tick event produce a location that differs SO GREATLY from this OnRelease event? What am I doing wrong to have such a drastic discrepency on its location in a replicated fashion?

Trying to get Steam OSS working on my project, and I'm getting an API disabled warning. Trying to follow this doc [https://wiki.unrealengine.com/Steam,_Using_the_Steam_SDK_During_Development], but I'm using retail (binary) Unreal 4.21 and can't modify build.cs or target.cs.

@visual creek - do you have Steam plugin enabled in project
Do you have DefaultEngine.ini configured right?

Lastly - Binary build you call it - you need to have Source build to do anything with servers - PIE testing in editor only goes so far - and it does NOT support steam integration

what is the proper way to SetActorLocation on a dedicated server? The server registers everything fine, but X and Y come up as 0 on the client so the character glitches before it gets to the destination.

exotic salmon Apr 13, 2019, 7:12 PM

#

I honestly am not sure but to reduce player perception vs real result, maybe you can hit scan on client, send to server, hitscan on server, check if close enough to what the client got and return allow or don'tAllowButUseThisResultInstead

#

If the client hits a fast moving pawn and on the server it does not but the hit isn't un-believable then you could just allow the client to use its hit.

@limber mortar you should try spawning a particle at that location serverside or something, see if it pops up

#

or spawn an actor

#

will probably help you narrow down if it's an issue of the event firing, or the location being wrong

"You can now set certain required Steam values, such as dedicated server names, or the application ID, in your project's Target.cs file. Making changes to these values will no longer require recompiling the engine."

Are there any fixes to choppy / low frame rate ANIMATIONS not just position when viewing a client as a listen server host?

#

Can repro in a default third person template, run around as the server and everything is smooth as butter from the clients point of view, but if you run around as the client, he is extremely choppy from the servers point of view and this is NOT just a movement replication issue as his actual animation seems to tick at a really low rate

#

You can debug this by increasing the Listen Server Network Simulated Smooth Location / Rotation Time up to large amounts

#

The replicated position / rotation is now smooth as butter but the animations themselves are running at what looks like about 10 fps or less

#

I guess an optimization but it's working great now

worthy perch Apr 14, 2019, 5:21 PM

#

It works? I haven't tried it out for myself. Let me know if you have any problems with it.

grizzled stirrup Apr 14, 2019, 5:22 PM

#

I just set that bool bOnlyAllowAutonomouseTickPose to false (in the reddit post they actually changed the Character.cpp file, but I think overriding PossessedBy and setting the bool again even though it was just set achieves the same thing without needing a source build)

#

That seems to tell UE4 to allow ticking the anims as usual and not only on a net update

#

Also another problem I had with pawns not possessing properly was due to my FPS being too high in PIE, another thing I have to remember- capping to 60 for debugging seems to eliminate the problem

#

Ok actually interestingly I DON'T think bOnlyAllowAutonomousTickPose was the culprit- it was having high FPS

#

Testing with t.MaxFPS set to 30, both the server and client look smooth regardless of whether that bool is true or false

#

When I set t.MaxFPS to 240, the client is a slideshow on the server

#

Only in terms of animation and not his actual position as that is super smooth for debugging

grizzled stirrup Apr 14, 2019, 5:55 PM

#

Ok so after some testing, it seems that if the client has a high frame rate (greater than 144 fps), there are MANY issues that can occur-

The client may not possess the pawn spawned for him
The server and other clients will see the client with an extremely choppy / low frame rate animation, even if the movement itself is smooth
The movement itself on the server can become choppy even with high interpolation values and a high update rate and unlocked bandwidth

#

So I guess as it stands, for a listen server game it's best to manually cap the fps to say 60 or 90?

grizzled stirrup Apr 14, 2019, 6:26 PM

#

Testing and it seems the sweet spot is T.MaxFPS 144

#

Anything above that (especially over 200) and the movement AND animation frames of a client (From the viewpoint of the server) becomes about 1 update a second

#

This in ONLY for the client FPS, the server can have 240 fps and run smooth on both

Hey(just a heads up I’m not to well know with Unreal yet). I’ve been working on a little project for a days now. I’ve got up a basic Multiplayer system. And I mean very basic.

But only that player sees the matinee happen. Any thoughts on my problem?

i have a pretty simple question that i couldn't find an answer for in the vast spider web we have
so i have an actor that is a template for guns and i made a couple child actors , but when i spawn both guns i can't control them at the same time because they both take the same input from the player so what happen is the last spawned gun takes over and the first spawned gun gets ignored , and i want to be able to activate any one of them when ever i want

limber mortar Apr 15, 2019, 2:05 AM

#

you'll probably have to show some blueprint or code

#

can you create a bool variable to see if a gun is active

#

and only apply the control set after a branch with the gun being active?

#

so a bool in the template

#

and each gun would have an IsActive bool or similar

#

or wait, you want them both at the same time

#

well, that could work still with a little more logic

old hamlet Apr 15, 2019, 2:09 AM

#

📎 yessss.jpg

#

i have to spawn them all first then disable the ones i don't yet need

#

then when i want to switch i enable one and disable the other

limber mortar Apr 15, 2019, 2:23 AM

#

So just to ensure I understand your question properly. Are you saying you want to be able to use any of those 3 activated weapons whenever you want, but the last one is the only one responding to controls

old hamlet Apr 15, 2019, 2:25 AM

#

Yes

#

@limber mortar because these actors you see me spawning are all child actors , and i scripted the parent to take input via custom events after i referenced my player t the parent

limber mortar Apr 15, 2019, 2:29 AM

#

ok, I think I understand what you're trying to accomplish. The code you showed just handles the creation though. Does that work how you want? Can you late on unhide and hide those actors as the weapons are pulled out / activated

#

I'm just talking visibility wise at the moment

#

If all the weapons take the same controls from the template's input

#

I'd think you'd need a variable in the template so you could track which are active and which are not

#

and then do a loop for all active weapons

#

that's without seeing additional code

old hamlet Apr 15, 2019, 2:32 AM

#

yes visibility works okay when i switch between them

#

because they are all created and they don't cancel each other

#

but how though they are all made up of the same template and that variable would check for all of them

limber mortar Apr 15, 2019, 2:33 AM

#

when you put the variable in the template

#

each child actor should have their own copy

#

right?

#

so each weapon would have an 'IsActive' bool

#

derived from the template

old hamlet Apr 15, 2019, 2:34 AM

yes but after i set them to actor variables they don't really allow me to access the variables within them

@modest hedge my PlayerState is set correctly in my GameMode, and I switched my Get Player Controller to Get Player Owner in my HUD class (which is also set correctly in my GameMode). Everything works fine for the host but clients still returning Null when trying to access their own player state -_-

#

do clients not have access to their own player state?

modest hedge Apr 15, 2019, 2:45 AM

#

when are you doing this, it could potentially be that the player state hasn't replicated yet

#

maybe try adding a delay of 1 second then setting the player state

old hamlet Apr 15, 2019, 2:47 AM

#

@limber mortar do you give up ?! xD

limber mortar Apr 15, 2019, 2:49 AM

#

um not necessarily, I have my own problem I am working on

#

but I've seen how you hide and show the weapons, not how you fire

#

how is your master class taking the input for firing and using the gun

It sounds like the only place we should need to adjust things

since the weapon changing works

yeah, I'm on my first project and while I have found many answers on the web. I've have had 3-4 problems that took weeks to fix

old hamlet Apr 15, 2019, 3:13 AM

#

i assume you are more advanced than me so i'm no good to help but i'll try anyways

#

hit me

winged badger Apr 15, 2019, 6:43 AM

#

@old hamlet if all your guns inherit from the same base class, you make a variable of base class type, say ActiveWeapon in whatever class you use to spawn and/or control weapons, you add functions like Fire, Reload etc... in your WeaponBase, and in your WeaponComponent/Character you handle weapon inputs like so FirePressed->GetActiveWeapon->Fire

Hey guys, I'm trying to destroy an actor that is referenced in the game state. It works if the execution is called from a listen server, but the client can't do it, even if I call an RPC

#

if (ProgressBar == 100.f)
    {
        
        if (HasAuthority())
        {
            Server_ScoreFlag();
        }
        else
        {
            RPC_ScoreFlag();
        }
    }

winged badger Apr 15, 2019, 6:48 AM

#

clients do not own the GameState

#

you'd have to send an RPC in an object owned by the client's PC

#

then call the Destroy in the GameState from inside that RPC

stark hull Apr 15, 2019, 6:51 AM

#

I see, but I have the progress bar runnning on the game state, is there a way to notify the client that the progress bar has reached 100 and then from the client I would make the RPC

winged badger Apr 15, 2019, 6:51 AM

#

if you have a progress bar server side

#

then server can just get rid of the Actor itself, no need for a RPC

#

if you need to get the progress bar ticking for client, from player input, then you start doing that with the method described above

#

and you can just run the timer on server and have the client simulate it

#

as in, start ticking its own version of the timer locally

stark hull Apr 15, 2019, 6:56 AM

#

yup, I see, I thought I had the timer ticking server side, but it seems that because I'm using a delegate, it might be doing something funky. Here is the call to "set timer" via delegate:

if (ACaptureTheFlagGameState* const GameState = GetWorld() != nullptr ? GetWorld()->GetGameState<ACaptureTheFlagGameState>() : nullptr)
    {
        if (ACaptureTheFlagPlayerState* CurrentPlayerState = GetPlayerState<ACaptureTheFlagPlayerState>())
        {
            GameState->OnFlagCapture.Broadcast(CurrentPlayerState->GetPlayerId(), StoredFlag);
        }
    }

#

I make this call inside a Server function

#

and this is the function that is bound to that delegate

void ACaptureTheFlagGameState::BeginCaptureTimer(FString PlayerName, AFlag* Flag)
{
    StoredFlag = Flag;
    SecondsTillFlagScore = GetDefaultGameMode<ACaptureTheFlagGameMode>()->SecondsTillFlagScore;
    if (FlagCaptureTimer.IsValid())
        return;
    CurrentOwningPlayer.Name = PlayerName;
    if (!PlayerScores.Contains(PlayerName))
    {
        PlayerScores.Add(PlayerName, 0);
    }
    CurrentOwningPlayer.Score = PlayerScores[PlayerName];
    GetWorld()->GetTimerManager().SetTimer(FlagCaptureTimer, this, &ACaptureTheFlagGameState::AddPlayerPoints, 0.1f, true);
}

#

Once the timer finished, I tried calling the destruction function, but got it to work only on listen server, not on client

winged badger Apr 15, 2019, 7:00 AM

#

server should have the sole authority over that

#

also, for adding player points, really

#

those just get replicated as a variable

#

as in, if your capture starts when the player is near the flat

#

server detects the proximity, starts the progress bar if visible, and starts adding PlayerPoints

#

when the flag is captured it destroys it

#

only thing you really need to do is replicate some stuff back to the client, so players know whats going on

#

if instead, player needs to click the flag, press E key or whatnot

#

you send a RPC through the PlayerController/PlayerCharactger/PlayerState

#

that starts the interaction server side

#

and same as above, you just replicate the stuff you need for visualizing interaction/progress to the client(s)

stark hull Apr 15, 2019, 7:07 AM

#

yup, it seems that I do relatively what you're saying in terms interaction (I send the request to the server to start the timer on interaction), but the callback inside game state never seems to replicate the destruction to the other clients, if a client interacted with the flag

winged badger Apr 15, 2019, 7:08 AM

#

if DestroyActor is called on the server, and the Actor is replicated

#

it will go away, on every machine

#

callback that destroys an Actor doesn't need to run client side at all

stark hull Apr 15, 2019, 7:09 AM

#

you speak of the AActor::Destroy() function right

#

?

winged badger Apr 15, 2019, 7:09 AM

#

you don't?

#

if the Actor persists after interaction

#

then PlayerState is best used to send the RPCs through

#

when the interaction is completed server side, you set the ControllingPlayer variable on the flag Actor, and in the OnRep function you handle the client side visualization

#

of type PlayerState or a class derived from it

#

so first thing you need to figure out is if you actually started the interaction server-side at all when the client wants to itneract

#

or you just started a client side simulation of it

stark hull Apr 15, 2019, 7:15 AM

#

The interaction is definitely working, since I do an RPC call from a client that attaches the flag to the client mesh. It persists across other machines

#

The problem could lie within the fact that I pass around a pointer to the Flag, and that property is not marked as replicated (But I do set the AActor defaults to make sure the actor replicated)

winged badger Apr 15, 2019, 7:19 AM

#

any Actor loaded from Package, replicated or not, and every replicated Actor can be referenced over the network

stark hull Apr 15, 2019, 7:19 AM

#

I see

#

Then I can only assume that the timer is not being launched server side

winged badger Apr 15, 2019, 7:20 AM

#

you may notice that PlayerArray in GameState, for example, isn't marked as replicated either

stark hull Apr 15, 2019, 7:20 AM

#

I see what you mean

#

It's really weird for me because the GameState function that is supposed to destroy the flag, also sets a couple of variables across different machines and are in sync (mostly stuff for UMG)

winged badger Apr 15, 2019, 7:24 AM

#

you can reproduce the problem in PIE?

stark hull Apr 15, 2019, 7:25 AM

#

yeah

winged badger Apr 15, 2019, 7:25 AM

#

then build DebugGameEditor binaries, start the editor from VS with F5 and set a couple of breakpoints

#

that should clear up whats really happening there

#

Flag variable not being replicated could cause a problem, or missing DOREPLIFETIME

#

if the variable is set only server-side

#

then the Actor can be referenced just fine, only client has no idea what that Actor is

#

you can open locals when your Breakpoint hits inside PlayerState

#

and GameState

#

and add its Role to watch window, that should make it easy to track if your breakpoint hit server or client side in Visual Studio

stark hull Apr 15, 2019, 7:29 AM

#

So the function that is supposed to be called from the game state is being called twice

#

one time the flag is null, the other it is valid

#

and it does call Destroy() on it, but remains in game

#

I suppose the timer is being set for both client and listen server, that could be the cause

#

Ok, found the issue, when the client requests a pickup, the listen server's replicated game state doesn't get a variable to the flag, causing the deletion to only happen on pickup instigator

#

If the listen server instigated the pickup, both the client and the listen server replicated game states get the variables

#

interesting

thin stratus Apr 15, 2019, 8:18 AM

#

server's replicated game instance

#

What is a replicated GameInstance?

bitter oriole Apr 15, 2019, 8:19 AM

#

I'm guessing he meant GameState

real yacht Apr 15, 2019, 8:24 AM

#

is epic online subsystem going to support as steam subsystem nat punch? is there going to be option to play 1vs1 with friend request?

#

i didn't find that information

stark hull Apr 15, 2019, 8:26 AM

#

yeah game state

#

my b guys xD, it's 2:30am lol

bitter oriole Apr 15, 2019, 8:27 AM

#

@real yacht No one knows since the Epic OSS isn't out yet

real yacht Apr 15, 2019, 8:31 AM

#

one more question, do you think that is overkill to spawn one dedicated server instance for 1vs1

#

than despawn instance when is finished

thin stratus Apr 15, 2019, 8:32 AM

#

It's basically the only thing you can do if you use ue4s servers

#

Despite ListenServers

#

But if your game shouldn't allow cheating, that#s not an option

real yacht Apr 15, 2019, 8:33 AM

#

yea, make a sense

#

one thing, in BP we can't have _validate as in c++

#

so without validate function RPC is valid to use for some calculation on server

#

my question is, if i'm not using _validate in c++, and only BP implementation, is that correct

#

?

winged badger Apr 15, 2019, 8:36 AM

#

_Validate isn't there to correct client side "mistakes"

#

its there to boot cheaters out of the game

real yacht Apr 15, 2019, 8:36 AM

#

i know

#

in validate i can check is healt> maxhealth and prevent cheating

#

understand

winged badger Apr 15, 2019, 8:36 AM

#

in 1 vs. 1, you would hardly get anythign useful out of it

real yacht Apr 15, 2019, 8:37 AM

#

so with RPC (FireProjectile on Server) in BP

#

is valid without c++ implementation?

thin stratus Apr 15, 2019, 8:38 AM

#

Sorry?

winged badger Apr 15, 2019, 8:38 AM

#

yes, that question didn't make sense

real yacht Apr 15, 2019, 8:39 AM

#

okay, my bad... this is question: Doing multiplayer in BP without c++ is correct?

thin stratus Apr 15, 2019, 8:39 AM

#

It can be. There is also a lot of stuff not properly exposed to BPs.

real yacht Apr 15, 2019, 8:39 AM

#

except that, is correct

thin stratus Apr 15, 2019, 8:39 AM

#

But I can't tell you if this will keep your from creating your game.

real yacht Apr 15, 2019, 8:40 AM

#

i'm not running from c++, just asking am i doing someething wrong

#

because for our demo, concept, we have done everything in BP

#

so i'm starting to ask myself is that correct way

winged badger Apr 15, 2019, 8:40 AM

#

personally i dislike doing any networking in Blueprints

thin stratus Apr 15, 2019, 8:40 AM

#

As said, you can do Multiplayer in BPs

#

It's just that there is lots of stuff not exposed to BPs

#

Which makes Multiplayer trickier in BPs

#

Variables, Functions, Types. All sorts of stuff not available.
You might never reach it, or maybe you reach the limit tomorrow when asking yourself how to do XY and the answer is: You can only do that in C++ (or via a Plugin).

#

Really depends on what you are doing ¯_(ツ)_/¯

winged badger Apr 15, 2019, 8:42 AM

#

its verbose, hard to read, RepNotify behaves differently then c++, you have limited control over the construction, and you can't use any customo networking solution

real yacht Apr 15, 2019, 8:42 AM

#

yea, so mix little of everyhitng

#

is okay

thin stratus Apr 15, 2019, 8:42 AM

#

Yus

real yacht Apr 15, 2019, 8:42 AM

#

everything*

thin stratus Apr 15, 2019, 8:42 AM

#

If you can, post prototype/demo, use C++

#

At least for the networking part

winged badger Apr 15, 2019, 8:43 AM

#

one piece of advice: when you spawn an Actor that needs custom initialization, use ExposeOnSpawn variables

#

its the only way in BP to have same variables ready on client and server by the time BeginPlay is called

#

(they will be set on server before BeginPlay, and those that are replicated will replicate before client side BeginPlay is called)

real yacht Apr 15, 2019, 8:46 AM

#

thnx for advice guys

can anyone tell me what a good inrate our outright might be ? my game is around 3500- 5000 bytes (per second, per packet?) but when at 7-11k things seem to break. is there a limit i need to raise?

worthy perch Apr 15, 2019, 11:48 AM

#

The default outrate (or inrate?) limit is 10k, you would want to raise that.

twin juniper Apr 15, 2019, 12:04 PM

#

Hey, can anybody help me please?

median elbow Apr 15, 2019, 12:07 PM

#

you should just ask your question rather than asking if you can ask a question

#

I'm having an issue with network relevancy. I understand the idea, and how replication works, but i'm having trouble figuring out how i would pass events only to a group of people

#

basically, think of a small multiplayer town. everyone can roam around the town and play with each other. Say there are guilds, and there's one building for guilds to go to. every guild goes to this main building, but when you go inside, its YOUR guilds setup in there. you don't see other guilds inside the same building, you only see members of your own guild. The inside of hte building is the same for all guilds, but they can set it up however they want, and other guilds will not see what they've done with the place

#

i can't seem to understand how this would be done in replication. If you tell someone to stream that map, thats fine, because everyone gets that same map, but how would you only have actors replicate in that map only for a subset of players?

#

another example is like a minigame in a large map. maybe a group of people jump in to play the minigame. multiple instances of this minigame might be running. how do we make sure that events and actor replications from one instance does not get to players in another instance?

modest hedge Apr 15, 2019, 12:13 PM

#

I haven't used it myself, but I think the replication graph will help you achieve want you want

#

https://docs.unrealengine.com/en-US/Engine/Networking/ReplicationGraph

median elbow Apr 15, 2019, 12:13 PM

#

i think replication graph would work for this

#

yeah

#

but my problem is i can't seem to find information on how to write a custom replication driver

fossil spoke Apr 15, 2019, 12:13 PM

#

Its called Instancing. UE4 doesnt support this out of the box as its not geared towards MMO style games which make heavy use of that technology.

median elbow Apr 15, 2019, 12:14 PM

#

THANK YOU devils

#

thats basically what i wanted to know

#

i wasn't able to find a solid answer on that

#

so replication graph is probably what i need then

#

from my understanding

fossil spoke Apr 15, 2019, 12:14 PM

#

Probably not

median elbow Apr 15, 2019, 12:14 PM

#

no?

#

shoot

#

in fact, this is not really a large mmo game

fossil spoke Apr 15, 2019, 12:15 PM

#

I mean you could try sure. But from what ive heard its not production ready at all and also not really what you would use it for.

median elbow Apr 15, 2019, 12:15 PM

#

hmm, ok

#

i guess the one solution i didn't want to do, but might be ok, is to just launch an instance of that map way off in the world somewhere

#

just make sure instances of it are far enough so replication doesn't happen for players in another "instance"

#

i didn't want to do it like this, it feels kind of hacky, but i won't have a large number of actors in the game, so even if everything got replicated its not a big deal

#

i just don't want one game to affect another

fossil spoke Apr 15, 2019, 12:17 PM

#

Look at third party solutions like SpatialOS. That would be geared to help you achieve that.

median elbow Apr 15, 2019, 12:17 PM

#

ok thanks devlisd

#

so just to be sure, how do you send chat to players only in your team for example?

#

oh wait

#

no, thats not actor replication, nevermind

fossil spoke Apr 15, 2019, 12:18 PM

#

UE4 was designed for single dedicated server instances that have 1 map loaded. IE: FPS games.

median elbow Apr 15, 2019, 12:18 PM

#

yeah, was just hoping there was some way still

fossil spoke Apr 15, 2019, 12:19 PM

#

Its not tooled for this type of Instancing you want. You would have to setup that yourself.

median elbow Apr 15, 2019, 12:19 PM

#

i've always written my own engines, just figured i'd give eu4 a shot so the designers could help build the game

fossil spoke Apr 15, 2019, 12:19 PM

#

Pick the right tool for the right job.

median elbow Apr 15, 2019, 12:20 PM

#

i might still look into replication graph though. i think even if i were forced to user their spacial partitioning graph, i could still make it work

fossil spoke Apr 15, 2019, 12:21 PM

#

Go for it. Ive heard that its a nightmare to work with though at this stage

median elbow Apr 15, 2019, 12:21 PM

#

yeah, i haven't heard anybody say that, but from my bit of research into it, it does seem like it

#

i can't find much on it at all unfortunately

#

i might just have to go into the source and dig around

fossil spoke Apr 15, 2019, 12:22 PM

#

You will have to. No doubt there.

median elbow Apr 15, 2019, 12:22 PM

#

haha

#

ok, well thanks devilsD, i guess i wasn't sure if there was already some solution in ue4 for this or not

#

looks like not, so thats helpful to know at least

fossil spoke Apr 15, 2019, 12:23 PM

#

Not out of the box at least. Third party solutions yes.

median elbow Apr 15, 2019, 12:23 PM

#

i'll check out spatialos, thanks for the tip

winged badger Apr 15, 2019, 12:23 PM

#

thats a dedicated server setup @median elbow ?

median elbow Apr 15, 2019, 12:23 PM

#

yes alo

winged badger Apr 15, 2019, 12:24 PM

#

you could try putting several streaming levels in the same place

#

then make only the relevant one visible

median elbow Apr 15, 2019, 12:24 PM

#

thats literally what i want to do actually

#

i just don't know how you would only have the relevant level stream to the correct players

winged badger Apr 15, 2019, 12:25 PM

#

guessing here, but it could be as simple as setting the streaming level visible for a client when it enters a trigger

#

it is done per controller, so you have access to player state as well

median elbow Apr 15, 2019, 12:26 PM

#

that is what i was truly hoping for, i wasn't sure if the level counts as a top level parent or something though

#

wait, each level has a list of all actors right?

#

so an actor can see what level hes in?

#

zlo, i think your right actualy

winged badger Apr 15, 2019, 12:27 PM

#

you shouldn't have actors that are not loaded

#

and those that are not visible shouldn't affect anything iirc

median elbow Apr 15, 2019, 12:27 PM

#

although ,i'm confused, i read that if you steam a level, then ALL players have ot stream that level?

#

maybe thats not a problem?

#

i don't care if the yall have the instance

winged badger Apr 15, 2019, 12:28 PM

#

i am reasonably sure its done per controller

median elbow Apr 15, 2019, 12:28 PM

#

i just need to make sure that they do not affect each other

winged badger Apr 15, 2019, 12:28 PM

#

and that its just default implementation that will iterate over all of them

#

you would have to look into source for it

median elbow Apr 15, 2019, 12:28 PM

#

thats awesome, i think thats at least a start, i didn't think about how the level might just not have to be visible

#

but what about other players then?

winged badger Apr 15, 2019, 12:29 PM

#

its possible it has to be unloaded as well

median elbow Apr 15, 2019, 12:29 PM

#

can you make it so players in one streamed level are not visible to players in another one?

winged badger Apr 15, 2019, 12:29 PM

#

net relevancy might do it

#

RealViewer there is the PC

#

so you return false if its Pawn is inside the guild and not a member of the same guild

median elbow Apr 15, 2019, 12:30 PM

#

whats realviewer?

winged badger Apr 15, 2019, 12:30 PM

#

first argument in AActor::IsNetRelevantFor

median elbow Apr 15, 2019, 12:31 PM

#

thats perfect i think!

#

ok, thanks zlo, i'm going to try to do it this way and see where i get

winged badger Apr 15, 2019, 12:31 PM

#

there might be several issues to iron out there, even if it works

median elbow Apr 15, 2019, 12:31 PM

#

yeah for sure

#

but could be a good start

#

i mean, worst case scenario really i'll probably just have to offset the levels so they are not overlapping each other i think

#

the game itself is not big, and not a ton of players on each server

winged badger Apr 15, 2019, 12:32 PM

#

you can have the guild hall entrance teleport them as well

median elbow Apr 15, 2019, 12:32 PM

#

yeah exaclty

winged badger Apr 15, 2019, 12:32 PM

#

to their guilds guild hall

median elbow Apr 15, 2019, 12:32 PM

#

there will be a "transition" zone

#

the whole guild thing was actually just kind of an example

winged badger Apr 15, 2019, 12:32 PM

#

it is a much simpler solution to implement

median elbow Apr 15, 2019, 12:32 PM

#

the game itself is a bunch of minigames

#

which are part of a larger "match"

#

there are transition zones between each minigame to give hte next level a chance to load and whatnot

#

so yeah, probably the fallback is to just offset the actual levels

#

i'm ok with that, was just wondering if there's a better way. i wil ldefinitely try to work with the isrelevant stuff and the map visibility

#

i hope that works

winged badger Apr 15, 2019, 12:34 PM

#

ideally, you wouldn't load other guild hall levels at all

median elbow Apr 15, 2019, 12:34 PM

#

yeah, that would definitely be preferred

#

i mean, in the end if network is slow because everyone is loading everything else or something, i'll just spend some extra time to do some coding. was just wondering if there was something in hte engine itself i could use

#

thanks Zlo!

hi guys, anyone know if attaching actor to component automatically replicates if attachment was called and only from server? or do I need to use RPC to trigger across all clients? Thanks in advance

winged badger Apr 15, 2019, 1:16 PM

#

it does, as long as whatever you are attaching replicates as well

fluid flower Apr 15, 2019, 1:19 PM

#

@celest geyser What I meant was that I don't think controllers exist on every client. So unless that function you're calling is on the server, I don't think it will work.

#

and as for how to get player states from gamestate, try this: https://api.unrealengine.com/INT/API/Runtime/Engine/GameFramework/AGameStateBase/PlayerArray/index.html

PlayerArray

Array of all PlayerStates, maintained on both server and clients (PlayerStates are always relevant)

celest geyser Apr 15, 2019, 1:24 PM

@fluid flower Aaah, of course, that makes sense! Aaaah and PlayerArray is already an array for the PlayerStates, I thought it was aan array of PlayerControllers, my mistake. Thanks for clearing that up, I'll try and use that. But I still have to match the PlayerState to the correct PlayerController, right?

fluid flower Apr 15, 2019, 1:25 PM

#

np 😃 and about matching playerstate to playercontroller, depends on what you want to do

celest geyser Apr 15, 2019, 1:26 PM

#

To get the value of a variable of the PlayerState of the owning client

fluid flower Apr 15, 2019, 1:28 PM

#

if you want the one from the owning client, you can do that directly from the widget. Call GetOwningClient first, then get playerstate from that value

#

so againg, it really depends on what this widget does. If the widget displays your own score, then just call GetOwningClient -> PlayerState

#

if widget is showing score of ALL players, then use GetGameState() -> PlayerArray -> foreach -> PlayerState->getpawn

celest geyser Apr 15, 2019, 1:30 PM

#

ah, nvm, it's a bit more complicated than that, it displays the value of the variable of all the connected clients, not only the local one. That's why the Controllers not existing on all clients becomes a problem

#

yeah, the last one is what I'm building right now, that seems to be the correct path, thanks for you help!

fluid flower Apr 15, 2019, 1:31 PM

in BP its called something like PawnPrivate

keen thorn Apr 15, 2019, 2:01 PM

#

@winged badger thanks for ur answer, do u know if the actor only or both the component and actor need to be replicated?

thin stratus Apr 15, 2019, 2:02 PM

#

@fluid flower Is that a new thing?

#

In 4.20, my PlayerState has no PawnReference

chrome bay Apr 15, 2019, 2:05 PM

#

yeah it's new

winged badger Apr 15, 2019, 2:05 PM

#

component doesn't but you need to be able to reference it over the network

#

so either a replicated component, or a default subobject on replicated Actor/Actor loaded from package @keen thorn

celest geyser Apr 15, 2019, 2:17 PM

#

Ok, another weird thing (again, a text binding in a widget):
this code correctly returns all connected player controllers when I open the widget on the server, but not on the client - there it only returns the server's controller
ConnectedControllers is a replicated variable on the GameState which all clients should be able to have access to (as I understand?)

📎 unknown.png

#

(I'm also clearing the OutputString variable before this runs, forgot to include it in the screenshot)

thin stratus Apr 15, 2019, 2:29 PM

#

PlayerControllers only exist for their Local Player

#

ClientA doesn't have ClientB's PlayerController

#

Sharing data between Players is done via the PlayerState.

#

@celest geyser

celest geyser Apr 15, 2019, 2:33 PM

#

ah, so I can't even store all PlayerControllers in an array on the GameState?

bitter oriole Apr 15, 2019, 2:34 PM

#

Nope

thin stratus Apr 15, 2019, 2:34 PM

#

Well you can, but only the Server will have a full array :P

celest geyser Apr 15, 2019, 2:34 PM

#

aaaaah

#

So if I have something that needs to execute on the local client (the Widget, because it only exists on the owning client, if I understand correctly) but that needs to run for each player in the session, what's the smartest way to get that list of players?

#

Would it be via the PlayerArray from GameState?

thin stratus Apr 15, 2019, 2:38 PM

#

Depends from where you call it

#

Does the Server have to notify everyone?

#

Is it something that originates already from the client?

celest geyser Apr 15, 2019, 2:39 PM

#

It's a text binding in a widget, just a debug window that shows all the relevant info for all connected players on each client and the server.

#

using it as a bit of a prototype to understand how info gets passed around/replicated

thin stratus Apr 15, 2019, 2:40 PM

#

Then the PlayerArray, yes

#

PlayerState -> Info per Player for everyone
GameState -> Info per Game for everyone
GameMode -> Rules and Server only code
PlayerController -> Server and owning Client code

#

Also please re-read the compendium

#

Cause that's all kinda explained there

celest geyser Apr 15, 2019, 2:41 PM

#

okay cool, let me give that a try, thanks for the help! 😃

Hello

#

Can anyone help me with a little question on PlayerControllers in CPP multiplayer?

#

So basically I have been trying to get the right PlayerController for the right player

#

I'm trying to make a gravity gun kind of thing work in multiplayer but my problem is that the object being picked up always returns to the first client connecting

#

My question is what is the best way to make a function that is being executed on the server know which player is picking up the object?

#

I can send a bit of code..

past rain Apr 15, 2019, 4:52 PM

#

Would anyone know why this would be happening? https://streamable.com/ibrmy Since the player is a pawn simulating physics, and not a character, there is no movement smoothing right? I don't know how I would go about fixing this

@dusky light run the RPC through the PlayerController, and have it send itself as function argument to the gravity gun thingy

fluid flower Apr 15, 2019, 5:20 PM

#

@past rain yeah if you don't use the char mov comp you have to do some work yourself. There's a some good information on it on valves wiki https://developer.valvesoftware.com/wiki/Source_Multiplayer_Networking

Source Multiplayer Networking

past rain Apr 15, 2019, 5:21 PM

#

First time doing multiplayer and networking, am I better off just using a character component

#

and learning this at a later stage?

fluid flower Apr 15, 2019, 5:21 PM

#

as a basic first step you can store every snapshot you receive from server, then interpolate between them ( for best result interpolate back in time a bit, not with last received )

#

yes, if your movement is close to something like a character, using the char mov comp will be a huuugeeeeee help

past rain Apr 15, 2019, 5:23 PM

#

It is... however

#

you play as a cube

#

so now I cant play as a cube anymore

#

because capsule component cant fit around it

#

not properly

fluid flower Apr 15, 2019, 5:24 PM

#

it doesn't have to be perfectly a cube

#

just get it close as possible

#

even if it was a cube, I'd go with a capsule because then sliding along corners will be much smoother

past rain Apr 15, 2019, 5:24 PM

#

the issue is, the corners of the cube

#

will clip

#

I could potentially remodel the cubes, so the corners are cut

#

if that makes sense

fluid flower Apr 15, 2019, 5:24 PM

#

yep, but in the grand scheme of things thats totally fine I think

#

I wouldn't worry about it at all yet

past rain Apr 15, 2019, 5:25 PM

#

Basically

#

At a very late stage, like

#

before the game is gonna get released

#

I can worry about changing the model slightly

right?

fluid flower Apr 15, 2019, 5:25 PM

dusky light Apr 15, 2019, 5:31 PM

@winged badger im not sure what you mean with run the RPC through the player controller, right now I have a function in the class of the weapon itself. Do you mean to move my code to a custom player controller class?

#

void ABallCannon::PrimaryFire_Implementation()
{}

#

.cpp ^

#

UFUNCTION (Server, Reliable, WithValidation)
virtual void PrimaryFire() override;

#

.h ^

winged badger Apr 15, 2019, 5:32 PM

#

PC handles the input, sends a server RPC, which calls a function to the gun that has the PC as an argument

#

if that function actually gets to server, and doesn't result in "No owning connection for..." warning in the output log

#

then you can pull the PC from ABallCannon, since it is its top owner

dusky light Apr 15, 2019, 5:36 PM

#

Uhm still not sure what you mean, do you mind if I add you as a friend?

winged badger Apr 15, 2019, 5:37 PM

#

i don't like helping over DM

dusky light Apr 15, 2019, 5:37 PM

no problem

frank copper Apr 15, 2019, 5:37 PM

it's better here, others can learn as well

dusky light Apr 15, 2019, 5:37 PM

#

Good point

winged badger Apr 15, 2019, 5:38 PM

#

so, in order to send a server RPC

#

the object has to be owned by a PlayerController

dusky light Apr 15, 2019, 5:38 PM

#

Oke let me explain my code first

#

That might make things more clear

winged badger Apr 15, 2019, 5:38 PM

#

if its owned by it, you can dig up a reference to it

dusky light Apr 15, 2019, 5:42 PM

#

How would I go about fetching the playercontroller from this weapon class?

#

I have tried to do it through the character which I have declared ownership of the weapon too

winged badger Apr 15, 2019, 5:42 PM

#

if Character is the weapons owner

dusky light Apr 15, 2019, 5:42 PM

#

Yeah

#

it is

#

And it can distinguish between the different characters on the server just fine

winged badger Apr 15, 2019, 5:43 PM

#

then Cast<APawn>(GetOwner())->GetController()

dusky light Apr 15, 2019, 5:43 PM

#

but the PlayerController is always the first one

#

Oke but from GetController I am not able to get the CameraManager

winged badger Apr 15, 2019, 5:43 PM

#

for that it has to be cast into PlayerController

#

AController doesn't have a PlayerCameraManager

dusky light Apr 15, 2019, 5:44 PM

#

Oke tried that and it ends up with a nullptr

#

Oke nevermind hold up

#

it might work

Oke yes it worked!

Anyone have any thoughts why 'spawn decal attached' would work in a multicast function but not 'spawn decal at location'? I verified via print string the location is correct and the created item was valid. I still can't see it though

exotic salmon Apr 16, 2019, 2:08 AM

#

My guess would be the rotation. Attached would take on some rotation of its parent while location could not be rotated to overlap its target

limber mortar Apr 16, 2019, 3:32 AM

#

thanks, I am going to look at that

#

I don't think it can be the rotation actually, the spawn decal at location gets it rotation from the attached module that works

#

📎 unknown.png

#

still going to look, but I use a rotator from a decal, same class, that works and shows up

#

unless the rotator is relative to the actor itself

#

wait, I think I also remember test cases where I adjusted each rotator value a bunch

stark hull Apr 16, 2019, 4:17 AM

#

@winged badger I figured out the problem that we discussed yesterday. Turns out the problem was really simple to fix. (I sorta memed myself)

#

void ACaptureTheFlagCharacter::Server_PickUpFlag_Implementation(AFlag* Target)
{
    Target->FlagState = EFlagState::Retained;
    UBoxComponent* BoxCollision = Target->FindComponentByClass<UBoxComponent>();
    BoxCollision->SetCollisionEnabled(ECollisionEnabled::NoCollision);
    Target->AttachToComponent
    (
        GetMesh(), 
        FAttachmentTransformRules::FAttachmentTransformRules
        (
            EAttachmentRule::SnapToTarget,
            EAttachmentRule::SnapToTarget,
            EAttachmentRule::KeepRelative,
            false
        ), 
        TEXT("FlagAttachPoint")
    );
    // start increment timer
    if (ACaptureTheFlagGameState* const GameState = GetWorld() != nullptr ? GetWorld()->GetGameState<ACaptureTheFlagGameState>() : nullptr)
    {
        if (ACaptureTheFlagPlayerState* CurrentPlayerState = GetPlayerState<ACaptureTheFlagPlayerState>())
        {
            //GameState->BeginCaptureTimer(CurrentPlayerState->GetPlayerId(), Target);
            GameState->OnFlagCapture.Broadcast(CurrentPlayerState->GetPlayerId(), Target);
        }
    }
}

#

See the last line where I call the delegate OnFlagCapture

#

I basically passed down a nullptr

#

and that's why it was deleting client side, and not server side

heyas. if you're watching this channel you'll know I've been working on this problem for a while... a LG style lighting beam weapon for a FPS. It's based on a line trace and beam particle. I've got it working OK, the only thing I want to fix up is having to send vectors for the line trace from server to clients for the multicasted cosmetic. This is beacuse I dont know how to reference the imitating players's camera manager data. Ideally, each client will be able to do it's own trace referencing the initating players camera location and rotation, without needing that data sent through . What's I've got is: the "arrow" is where the cosmetic initates from, while it should end at a location in front of camera rotation. My temporary solution is to do this every tenth tick to minimise network data. Ideas welcome, especially if you know how I might reference player camera location and rotation from other clients (I've tried sending through references to controller player controller, camera manager... all with same result which is client's dont know where other client's end poitns are).

With SpatialOS you build any game, with any engine on any platform. Ship it faster and innovate more easily.

I am evaluating the cost of a headless dedicated server with UE4 and comparing the result to that of Unity. So far it seems like unity is more efficient and that too by a very large scale. However, I would like to have more detailed dataset before I conclude. Game is something like Unreal Tournament.

PS: When I say cost, I am not referring to the cost of getting a server on AWS, Google, etc but rather how many server rooms I run on a single system.

Ignore the game complications, I am only considering the engine overhead cost.

Thanks.

Hi guys. I have a custom vehicle which is moving using ray trace and hover components I made

bitter oriole Apr 16, 2019, 9:28 AM

@spring swift Sounds like you need a RPC to trigger it on other clients

flint plaza Apr 16, 2019, 9:28 AM

#

I am able to replicate the movement successfully

#

but when I try to make all components of the actor replicated, the game starts to flicker

#

any ideas why?

#

@bitter oriole May i ask what a RPC trigger is?? im still a bit noodish on Unreal

bitter oriole Apr 16, 2019, 9:30 AM

#

You should read the docs on the UE4 multiplayer framework

#

Multiplayer is hard enough without knowing which tools are at your disposal 😃

#

RPC being the only feature to have a client communicate with others

#

https://docs.unrealengine.com/en-us/Gameplay/Networking/Actors

#

Read all that chapter

spring swift Apr 16, 2019, 9:32 AM

#

alright

thin stratus Apr 16, 2019, 9:43 AM

#

So I wonder, can I assume that the PlayerState exists on Server and Client when a Pawn gets possessed?

#

Cause I'm retrieving backend data (skins and stuff) and saving it in the PlayerState for a one-time replication.

#

Which the Pawn will access when being spawned/respawned

#

Don't want to run in yet another replication race :D

bitter oriole Apr 16, 2019, 9:44 AM

#

That does sound like a safe assumption

thin stratus Apr 16, 2019, 9:45 AM

#

Only thing that could happen I guess is that the replicated data is not yet there

bitter oriole Apr 16, 2019, 9:45 AM

#

Even that is dubious, because PC needs some playerstate data to actually do stuff

thin stratus Apr 16, 2019, 9:46 AM

#

Gotta keep in mind the delay of the backend fetch

#

Happens on Login

#

But you never know

#

But, let's implement and fix later I guess

real yacht Apr 16, 2019, 9:47 AM

#

@thin stratus you think that fetching data on login create some problems in future

#

in gameplay, etc?

thin stratus Apr 16, 2019, 9:48 AM

#

It's more like:

Player Login -> Creates PlayerController
PC retrieves (ServerSide) backend data. (takes time)
PC passes data to PlayerState.
PS replicates the data.
Pawn spawns and gets possessed
Pawn receives "OnRepPlayerState"
Pawn access replicated data from PlayerState.

#

If that goes wrong somewhere in timing, I need to readd my boolean/delegate system, where it checks if the boolean is true and if not binds to the delegate and waits.

real yacht Apr 16, 2019, 9:49 AM

#

why dont you do 1 and 2 in same line and after that create player controller?

#

login->fetch data..wait->create player controller

spring swift Apr 16, 2019, 9:53 AM

#

@bitter oriole Ive messed around and i noticed the custom event needs to be run by the server for the RPC to work. the Event is runned by the Client though so would you know how to make a button that can be used by the player that the server runs?.

bitter oriole Apr 16, 2019, 9:54 AM

#

RPCs can be called from clients or servers

#

Of course, whether the RPC actually works depends on other factors

#

Like ownership of the actor

spring swift Apr 16, 2019, 9:55 AM

#

ok let me see if i can find a way around this

bitter oriole Apr 16, 2019, 9:55 AM

#

Read the doc first

#

Most multiplayer problems are solved on paper

#

You'll want a graph of your classes, who owns them, where they exist ad how they can replicate

#

dont worry im still reading haha

flint plaza Apr 16, 2019, 10:19 AM

#

Anyone who can help with my situation written a bit above?

real yacht Apr 16, 2019, 11:23 AM

#

@flint plaza i think that is really specific for your game

#

and i think that question is really have abstract answer because it depends on lot of things..

winged badger Apr 16, 2019, 11:25 AM

#

@flint plaza why would you make all the components replicated?

#

only reason to make a component replicated is if its a custom component class that contains either replicated variables or RPCs

#

or it is dynamically spawned

#

as in, not a default subobject

flint plaza Apr 16, 2019, 11:50 AM

#

@winged badger yes I does. I have 4 hover components (1 for each wheel)

#

movement replication is not a problem. Just finished with it today

#

but when I was playing with it, I collided with the other players vehicle

#

and noticed that the same version of the game now had different variations of it running

#

as it the location and rotation of the vehicle different from the client and server version

#

So I wanted to make the components replicated

winged badger Apr 16, 2019, 11:53 AM

#

they are attached, right?

flint plaza Apr 16, 2019, 11:59 AM

#

yes

#

They are part of the pawn in the actor components

median elbow Apr 16, 2019, 12:42 PM

celest geyser Apr 16, 2019, 3:21 PM

OK, it seems like I still don't understand the PlayerState correctly... From the compendium I got that each PlayerController has its own PlayerState. I tried to mimic the example from the compendium to see if it would work correctly, but the result that I'm getting doesn't match my expectations based on my current understanding of the PlayerState class...

📎 unknown.png

#

I'd expect this code to increase the value of MyVariable by 1 when pressed, on the respective PlayerState of the PlayerController that is associated with the active window (Client or ListenServer)

#

but that's not what's happening, where's the mistake in my logic here?

cinder quartz Apr 16, 2019, 3:27 PM

#

is the variable replicated and server changes the variable? hard to see from that pic

#

nvm opened it bigger via browser

celest geyser Apr 16, 2019, 3:28 PM

#

Yes. If you press the 'Open Original' button under the pic, you dont get the terribly compressed discord one

#

😃

cinder quartz Apr 16, 2019, 3:39 PM

#

have you tried Get Controller instead of Get player control index 0 ? that BP is on your character/pawn right?

celest geyser Apr 16, 2019, 3:41 PM

#

Which BP? The one that calls the ServerIncreaseMyVariable? That's the PlayerController.

cinder quartz Apr 16, 2019, 3:42 PM

#

then you should not need to Get controller ? could just try Get player state node which doesnt need input if its in controller

#

Like this

📎 playerstate.JPG

celest geyser Apr 16, 2019, 3:46 PM

#

Ah, progress! Here I pressed "I" 3x on the server an once on the Client, which means that it seems to be replicating correctly now! 😄

📎 unknown.png

#

(server left, client right)

#

but the Names of the respective PlayerStates are still inconsistent O.o

cinder quartz Apr 16, 2019, 3:48 PM

#

hmm, keep in mind that Get player controller index 0 might be different on server and client so it might refuse to do something, if you call the functions on local player controller it should work

#

client doesnt know about other players controllers, only server has them all

#

but player state yes, every player should have player state on every machine

Right, and the PlayerStates should be consistently named across every machine, right? As in, if I have 2 connected Controllers, my PlayerArray in the GameState should be for example: [PlayerState], [PlayerState1]

#

across ALL connected clients, correct?

winged badger Apr 16, 2019, 3:54 PM

#

no guarantee of order

celest geyser Apr 16, 2019, 3:54 PM

#

Ah!

#

in the latest screenshot above, they have also switched names apparently O.o

#

is that not guaranteed either?

#

Thanks for you help thus far guys! It's really clearing things up for me 😃

winged badger Apr 16, 2019, 3:57 PM

#

each machine will call the first object of its class by Name, and append a number for each subsequent one

cinder quartz Apr 16, 2019, 3:57 PM

#

maybe you should multicast some values from gamestate ? so server says whats in what order to print ?

winged badger Apr 16, 2019, 3:57 PM

#

so order in which your client gets its PlayerStates replicated will determine the name, and the position in the PlayerArray

#

and that order is not quaranteed

celest geyser Apr 16, 2019, 3:58 PM

#

so each machine assigns a different name to each PlayerState based on the order in which they are replicated, did I understand that correctly?

winged badger Apr 16, 2019, 3:59 PM

#

pretty much

celest geyser Apr 16, 2019, 3:59 PM

#

I see, that's been a major source of confusion for me.... I've been trying to identify each PlayerState by name across machines T.T

winged badger Apr 16, 2019, 3:59 PM

#

technically, its the order they are constructed in, but their spawn process starts by receiving a Bunch in NetConnection

#

note that all Actors that are part of the package have same, stable names on all machines

#

and therefore do not need to be replicated in order to be referenced over the network

celest geyser Apr 16, 2019, 4:06 PM

#

What package are you referring to?

celest geyser Apr 16, 2019, 4:49 PM

#

By the way, I was using OnPostLogin to initialize the PlayerController and run a bunch of setup code, but it was giving me problems with not getting for example the correct PlayerState - this was not the case when I put a 1s delay after the OnPostLogin (I guess it needs some time to create the PlayerState for each PlayerController?). How is that usually handled?

What would happen if I 'paused' a game for a local client while on a server and then unpaused it some time later?

#

I'm not able to test this out right now so hopefully someone can shed some light.

#

If ue4 only allows 1 session per instance, then why bother with creating sessions? Just drop the session nonsense, and give me a list of instances

#

Or am I not getting it?

Is it possible to start multiple clients from the "Play" button without having any "listener" nor "dedicated server"?

twin vault Apr 16, 2019, 6:36 PM

#

yes, project settings

#

Automatically connect to server or smth

#

#

its on the editor settings, not project

modern token Apr 16, 2019, 6:54 PM

#

Ah yeah I see.

#

Oh ok it seems to be doing it, I don't need the dedicated server but it works haha, great thank you!

modern token Apr 16, 2019, 7:29 PM

#

Somehow I now have errors in my MainMenu blueprint when I select the dedicated server box

#

I set "Default server map" to None but it doesn't change anything. I have an error that my Construct Object from class node returns None :/ But I can still see my main menu in my client.

#

Oh waoh I feel so stupid, for some reason I thought that option was only available when Run Dedicated Server was checked... (Probably Linux UI issue hahaha)

#

Works fine, thanks again @twin vault 😃

slender yarrow Apr 16, 2019, 9:13 PM

#

anyone know of an up to date guide to make a dedicated server? That big one on the wiki only has information from 4.18, im using 4.21. Or does it work with 4.21?

bitter oriole Apr 16, 2019, 9:46 PM

#

Try that and follow

slender yarrow Apr 16, 2019, 9:56 PM

#

yeah after I follow it and build everything around step 5 I dont get the .exe file in binaries. I feel like its cause in step 3 the code for the Target file only goes up to 4.18 😟

slender yarrow Apr 16, 2019, 10:14 PM

#

actually nvm it worked. The building system in VS is a little buggy.

glacial pollen Apr 16, 2019, 10:45 PM

#

is servertravel in editor completely broken now? 4.22

#

NOT using seamless

#

NOT using AutoConnect

#

Dedi and player both load a blank map,
dedi is told to create a session
player is told to find and join
dedi then servertravels
player is refused connection 4 times (before dedi can even load the level)
LogNet: NotifyAcceptingConnection: Server DedicatedStartMap refused

#

player quits attempting to connect

#

And this is spammed forever:
LogWorld: Warning: SetActiveLevelCollection attempted to use an out of date NetDriver: GameNetDriver

#

player stays stuck in the DedicatedStartMap

#

And google search does not help, as everyone is either asking about steam, or the answer was to turn off seamless, or autoconnect, or no answer at all.

#

OR, the answer is to use StandAlone, but there is no way to debug (dedicated server) blueprints that way

@bitter oriole Ive set up a Custom event that is replicated from the server to the and the clients but once i get the player involved at all it only uses the Matinee to the 1 client and i cant figure out the way around...

clear copper Apr 17, 2019, 12:34 AM

#

Every player controller should be able to see the PlayerArray in the GameState right?

clear copper Apr 17, 2019, 1:02 AM

#

But if I want them to see variables in the playerstates in the player array I need to replicate them?

stark hull Apr 17, 2019, 2:47 AM

Hey guys, does anyone know why is it that I'm getting an exception when attempting to spawn an actor of type AFlag? (this function is called inside the gamemode)

void SpawnFlag(FVector Location)
{
    const AFlag* Flag = GetWorld()->SpawnActor<AFlag>
    (
        AFlag::StaticClass(),
        Location,
        FRotator::ZeroRotator
    );
}

#

The error is thrown here:

template< class T >
    T* SpawnActor( UClass* Class, FVector const& Location, FRotator const& Rotation, const FActorSpawnParameters& SpawnParameters = FActorSpawnParameters() )
    {
        return CastChecked<T>(SpawnActor(Class, &Location, &Rotation, SpawnParameters),ECastCheckedType::NullAllowed);
    }

#

I assume that the Class is null, but it's unclear why

stark hull Apr 17, 2019, 3:23 AM

#

hmm, so the call is a ok in begin play, but asking the game mode to spawn an actor from the game state causes an error

#

FIXED IT. Here is what I switched to make the spawning work

#

GetDefaultGameMode<ACaptureTheFlagGameMode>()

#

just don't

#

(ACaptureTheFlagGameMode*)GetWorld()->GetAuthGameMode();

Hi guys I am sending my position from client to server via RPC every 2 seconds to make it in sync in case the positions are not matching. But it is not working. Can someone check out what is being done wrong and guide me in the right direction as to how to do this. thanks

ivory portal Apr 17, 2019, 8:50 AM

#

Stupid question maybe but documentation isn't superclear about it

#

does playerstate persist through levels with seamless travel?

#

https://docs.unrealengine.com/en-us/Gameplay/Networking/Travelling#persistingactorsacrossseamlesstravel

#

Doesn't really tell yes

bitter oriole Apr 17, 2019, 8:51 AM

#

"Any actors further added via APlayerController::GetSeamlessTravelActorList called on local PlayerControllers"

#

Check that code
