triggers if bAcceptingConnection is false

thin stratus Jun 6, 2018, 9:12 AM

#

Just looked at it

#

It triggers if "bPassedChallenge" is false and yes if it accepts connections

#

Hmm

#

Seems to be running on tick though

#

So if it fails it just tries again

#

Welp, the Client seems to connect despite that warning

winged badger Jun 6, 2018, 9:16 AM

#

it might be a matter of timing

#

and it might be common occurence, considering most people don't log LogNet VeryVerbose

#

yeah, was tracing the wrong warning above 😦

#

with bAcceptingConnection

full bane Jun 6, 2018, 10:16 AM

#

is there a built-in way to monitor tick rate of a dedicated server?

lean hornet Jun 6, 2018, 10:28 AM

#

do you still need to follow this in current versions ? https://docs.unrealengine.com/en-us/Programming/Online/Steam

#

for using steam ?

full bane Jun 6, 2018, 10:30 AM

#

at least the config part, yes

#

the .dll's should be supplied though, at least v139

lean hornet Jun 6, 2018, 10:31 AM

#

so i dont need to manually update to v142

full bane Jun 6, 2018, 10:31 AM

#

only if you want to

#

not sure if there is anything new though

lean hornet Jun 6, 2018, 10:33 AM

#

I just followed these steps because i had alot of issues with connectivity and testing in the past few days

#

for example i cant even host sessions anymore in PIE

winged badger Jun 6, 2018, 10:35 AM

#

steam won't run in PIE

lean hornet Jun 6, 2018, 10:35 AM

#

but i was able to do it before no issue and i know that steam wont run

#

what can i do for testing in pie ?

full bane Jun 6, 2018, 10:35 AM

#

it falls back to a backup if steam doesn't run

#

so maybe you were able to find lan games

lean hornet Jun 6, 2018, 10:36 AM

#

im going to test hosting a lan game really quickly

#

also if i package a project do i need to pack steam into it ?

full bane Jun 6, 2018, 10:36 AM

#

or just try standalone

#

that should run with steam

lean hornet Jun 6, 2018, 10:37 AM

#

Okay Anything else than manuallly adding the steam_appid.txt

full bane Jun 6, 2018, 10:37 AM

#

you don't even have to do that

lean hornet Jun 6, 2018, 10:37 AM

#

oh ?

full bane Jun 6, 2018, 10:37 AM

#

unreal creates one if oyu added your appid in the config

lean hornet Jun 6, 2018, 10:38 AM

#

i did but it doesnt always do that for me for whatever reason

full bane Jun 6, 2018, 10:38 AM

#

do you see the overlay when starting standalone?

lean hornet Jun 6, 2018, 10:39 AM

#

now it works

full bane Jun 6, 2018, 10:39 AM

#

Shift + Tab

#

well, then it thats it

#

everything else should be a different issue

#

like not using sessions correctly

#

or wrong settings

#

ports

#

etc

lean hornet Jun 6, 2018, 10:40 AM

#

can i ask you one more thing ?

full bane Jun 6, 2018, 10:48 AM

#

bRelaunchInSteam, it's probably a good idea to set that to true

#

also is that your real appid?

lean hornet Jun 6, 2018, 10:49 AM

#

so like this ?

📎 unknown.png

full bane Jun 6, 2018, 10:49 AM

#

if that is the case, I think you have to write the steam support to whitelist your game for p2p usage

#

ya, I would try with 480 first

#

if that doesn't work, then dunno

lean hornet Jun 6, 2018, 10:50 AM

#

so i can remove the p2p usage ? i was just following the steamworks tutorial from steam thats why

full bane Jun 6, 2018, 10:50 AM

#

not even sure, tbh

#

how ue4 handles this internally

lean hornet Jun 6, 2018, 10:51 AM

#

So also if steam doesnt allow loading in pie whats the best way to test networking locally ?

#

because even after all those changes i still cant host locally

twin juniper Jun 6, 2018, 10:52 AM

#

you can use standalone, or a test build with your defaultengine.ini configged like that.

#

i always package out to test steam builds.

full bane Jun 6, 2018, 10:52 AM

#

or an editor shortcute with your project and -game as start parameter

twin juniper Jun 6, 2018, 10:53 AM

#

^

lean hornet Jun 6, 2018, 10:53 AM

#

What would i need to change to locally test it in pie for now ? i dont really need to use steam right now i just need to test networking in general

#

and haveing to package it out every time is a additional step wich i rather not take at this moment if possible

full bane Jun 6, 2018, 10:53 AM

#

for that you can just crank up the number of clients in the play drop-down

twin juniper Jun 6, 2018, 10:53 AM

#

if you want to test networking, just set it to 2 players and run it in UE..

lean hornet Jun 6, 2018, 10:54 AM

#

oh nvm i just realized i dont even have to host a session i can just open the map and PIE

#

Thank you both^^

twin juniper Jun 6, 2018, 10:55 AM

#

📎 unknown.png

lean hornet Jun 6, 2018, 10:55 AM

#

i got that part

#

everything works now.

twin juniper Jun 6, 2018, 10:55 AM

#

no problem, just wait until you have to do a dedicated server

#

😛

#

those are the best

lean hornet Jun 6, 2018, 10:56 AM

#

dont worry that wont be any of my issues anytime soon its a playerhosted simple game project xp

twin juniper Jun 6, 2018, 10:58 AM

#

@lean hornet "path to unreal binary\UE4Editor.exe" "path to game project\gameuproject" -game will get it to test locally, or you can use -server -game -log at the end for local server testing. taht';s what Denny was reffering to earlier

lean hornet Jun 6, 2018, 10:58 AM

#

Ohhhhhhhh

twin juniper Jun 6, 2018, 10:58 AM

#

yep

meager spade Jun 6, 2018, 1:46 PM

#

this is annoying me, trying to get an anim to replicate reliable but for some reason it just doesn't

#

works fine the first time, second time, it just doesn't animate

worthy wasp Jun 6, 2018, 5:33 PM

#

is there a way to make an HPBar (UWidget) face the character at all times - but be local? In a multiplayer setting - each local player would have enemies HP bars face towards the player character - but not be replicated in rotation.

I typically have pulled this off with a tick event, setting the rotation of the widget to the player if(!HasAuthority()) but this could get pretty expensive with 50+ enemies on the scene (which will be easily done in this game mode)

#

my thoughts were to use a MaterialBillboard - with a child widget parented to it - but this doesnt drive the rotation of the children unfortunately 😦

#

even though i'm doing this via C++ so it'll be fast - i still want to optimize this if i can.

full bane Jun 6, 2018, 5:37 PM

#

you can attach the widget component and set it to screen space

#

that should take care of everything automatically

worthy wasp Jun 6, 2018, 5:38 PM

#

ah lemme try that - thanks @full bane - let you know how this goes in a sec!

versed socket Jun 6, 2018, 5:48 PM

#

@worthy wasp You can make a widget component as part of the actors

worthy wasp Jun 6, 2018, 5:48 PM

#

is that it?

#

-💯

thin stratus Jun 6, 2018, 5:51 PM

Idk if I'm late to the party

#

But 4.20 has:

Networking Updates:
-Replication Driver / Replication Graph (Experimental)
--UReplicationDriver is a base class that can be used for implementing custom server replication logic.
--UReplicationGraph is an implementation of UReplicationDriver that provides a replication system optimized for games with large actor and player counts.
-Steam Authentication has been added.

worthy wasp Jun 6, 2018, 5:51 PM

:D hehe

full bane Jun 6, 2018, 5:54 PM

not too long ago I've spent a frustrating week of doing this

also the ReplicationDriver sounds amazing

thin stratus Jun 6, 2018, 5:58 PM

Anyone used GameLift before? How was your experience?

wary willow Jun 6, 2018, 7:30 PM

So, who knows how to use Replication Driver/Graph ? 😉

fleet sluice Jun 6, 2018, 7:39 PM

@wary willow Can't wait for 4.20-release?

sharp hornet Jun 6, 2018, 7:40 PM

wary willow Jun 6, 2018, 7:52 PM

@fleet sluice as long as they test

hasty adder Jun 6, 2018, 9:01 PM

#

Think that replication driver is foundation for instant replay maybe?

marsh gate Jun 6, 2018, 9:38 PM

#

How do we implement something like Fortnite's crossplay features?

#

Is this a difficult undertaking

fleet sluice Jun 6, 2018, 9:39 PM

#

@hasty adder Wasn't the UDemoNetDriver class supposed to handle everything about replays?

hasty adder Jun 6, 2018, 9:40 PM

#

Not sure. All I know is instant replay is on the todo list and I’m hoping the work will make it easier to implement stuff for live network games 😃

sharp pagoda Jun 6, 2018, 9:49 PM

#

@marsh gate I believe you have to design your own online subsystem that can cooperate with Steam, Xbox, PSN, etc. To answer your question yes it would be a difficult undertaking

hasty adder Jun 6, 2018, 10:10 PM

#

Doesn’t it all just come down to connection to the dedicated servers?

#

For instance you canoad game in steam and connect to a null dedicated server

sharp hornet Jun 6, 2018, 10:25 PM

#

Replication driver doesn't have anything to do with instant replay, it's a thing for optimizing network bandwidth and server cpu usage for large player counts

hasty adder Jun 6, 2018, 11:58 PM

#

Ah

wary willow Jun 7, 2018, 12:01 AM

#

@marsh gate crossplay, moderately difficult. Depending on platforms. But generally..

#

Need your own custom oss (or at the very least customize current ones)

#

Or a backend

#

Like GameSparks

#

I should have tried out PlayFab this go around

#

Maybe next time

#

But heard they are pretty good for cross platform as well since not only is it BaaS, they provide server solutions as well

marsh gate Jun 7, 2018, 12:35 AM

#

Or a backend... hmm

#

I'm planning on using AWS GameLift

#

@wary willow @sharp pagoda I'm not sure if they have that sort of functionality already built in, but if they do, that'll come in really handy. I have no idea what an Online Subsystem even is right now LOL.

@mellow cipher also what is steam auth i though ue4 already has steam

mellow cipher Jun 7, 2018, 5:29 AM

Steam auth checks if you own the game

When u join a server/game

Else pirated versions can play online too

I have a question about general session creation and session join, I've been using the NULL subsystem for this, when I create a session with a player (without server travel) and I dump the session details it shows 0 Registered Players, if I then join that session with another player (no client travel) and dump the session, it still shows 0 Registered Players also no players seem to be in that session from the NumOpenPrivateConnections. Do I require to travel to a Lobby Map in order for these players to register and start updating the NumOpenPrivateConnections?

How do I correctly get the ping of a server in my server browser? I am currently using in BPs: Session->GetPingInMs, but that one doesnt seem to be accurate or update unless I refresh the server browser multiple times, whats the best way to get the ping of a session, and update it every second?

bitter oriole Jun 7, 2018, 3:22 PM

#

You want every client to ping every server every second ?

#

Sounds like a really bad idea 😃

ruby meteor Jun 7, 2018, 3:28 PM

#

Maybe ping it a few times on server browser refresh, and then get the median value of all pings? the way I do it right now displays too high pings

thin stratus Jun 7, 2018, 3:49 PM

#

Pings aren't meant to update after you received the list. :D

full bane Jun 7, 2018, 4:30 PM

#

those pings aren't accurate anyway

#

depending on your oss

ruby meteor Jun 7, 2018, 4:45 PM

#

But the pings from the logs ('found server xxx with ping xx') seem to be much more accurate than my server browser pings

wary willow Jun 7, 2018, 6:20 PM

#

tbh

#

There are some external solutions

#

Just need to make something to ping current city to target city

#

or region

#

Depending on how much data you can get from each player, can be super accurate, or semi-

#

I was thinking about using GameSparks to do that eventually

#

But I think there are some other (maybe even better) solutions

prisma ore Jun 7, 2018, 8:34 PM

#

Hi guys, got a weird behavior with my MP Game ....

hasty adder Jun 7, 2018, 8:34 PM

#

Yeah pinging region is how rocket league works

#

It pings it’s server farm not the instance of server itself

prisma ore Jun 7, 2018, 8:35 PM

#

FPS game, when a client connects, if the host character is running around, then the client see the host player in the wrong spot !

hasty adder Jun 7, 2018, 8:35 PM

#

Then when connected it can run a routine with a time stamp message to get time sent time returned for live ping and split the time

prisma ore Jun 7, 2018, 8:39 PM

#

anyone has a hint for my issue ?

hasty adder Jun 7, 2018, 8:40 PM

#

Movement in the pawn set to replicate?

prisma ore Jun 7, 2018, 8:41 PM

#

yes, it replicates perfect if server host is not running around

#

the effect on the client is like the the local position of the character is being offset .. when i just look around on server, the client then see my skin move around my location on a big circle ... not sure how to explain properly

dull stream Jun 7, 2018, 8:48 PM

#

so I have the server spawn a bunch of cubes at begin play, but theres horrible "pop in" effect as the actors become relevant (?)

#

I want to be able to see them on the client from a distance

#

so okay I thought I should spawn them on the client, however that doesnt seem to work

#

I dont know what to do to fix this issue, theres gotta be some conceptual thing I am missing here

#

its just static objects

#

i should be able to see them from anywhere without communicating with server

twin juniper Jun 7, 2018, 8:55 PM

#

anyone know why my dedicated server game i hosted on ec2 might be 4.5 GB in ram use? if the answer is textures, i already set compression to 512, many of them are 4096. does unreal use the imported texture size in dedicated servers, or the compressed one?

📎 unknown.png

dull stream Jun 7, 2018, 8:56 PM

#

nvm i figured out my issue i had to replicate movement and make it always relevant i think

twin juniper Jun 7, 2018, 8:59 PM

#

B-ry if you spawn the actor using multicast it should work without replicates/replicates movement

#

otherwise yes you will need those.

dull stream Jun 7, 2018, 9:05 PM

#

I tried that

#

hm

#

it might be because i am spawning randomly sized cubes

#

server decides the random size

#

would it still work in that situation? because i tried a lot of things and it didnt seem to work for me

prisma ore Jun 7, 2018, 9:06 PM

#

check the network culling setting ?

dull stream Jun 7, 2018, 9:07 PM

#

@prisma ore you would still need to replicate to use that yes?

#

so i could replicate, but have the pop in only for really distant objects?

prisma ore Jun 7, 2018, 9:10 PM

#

the parameter is a distance (or distance squared, not sure)

#

so anything farther is culled

dull stream Jun 7, 2018, 9:11 PM

#

that did fix it, no longer need to always be relevant

#

im still a bit confused why i even need to replicate though, I guess its because i change the scale after its spawned

prisma ore Jun 7, 2018, 9:15 PM

#

nah, you replicate so every other client see the same thing as you

#

you being the server

dull stream Jun 7, 2018, 9:16 PM

#

right. hm. but it seems to me like if its a static object that doesnt move during game the client could just be responsible for what it sees, and server just handles collision. but maybe im thinking too deeply about this

prisma ore Jun 7, 2018, 9:17 PM

#

you are generating those objects at runtime, right ?

dull stream Jun 7, 2018, 9:17 PM

#

yeah I am. spawn random cube type at begin play, call a function on that cube type to get a random scale value

#

then use that random scale value to set its size

#

initially i was trying to use that random scale and spawn identical versions for each client

prisma ore Jun 7, 2018, 9:19 PM

#

Once the cube has been replicated, if it does not move or scale etc then no network data will update it so you're not losing bandwidth

dull stream Jun 7, 2018, 9:19 PM

#

ohhh okay thats good to know

#

so its not constantly checking for changes

#

the clients arent

prisma ore Jun 7, 2018, 9:20 PM

#

the server calculates a delta .. and if that gives a zero transform .. no need to replicate again

dull stream Jun 7, 2018, 9:20 PM

#

okay i see, thanks

prisma ore Jun 7, 2018, 9:21 PM

#

yw

dull stream Jun 7, 2018, 9:21 PM

#

so why do you think it culls then? if you've seen the object once, and you move away... is that just so you dont have inaccurate/out of date information about the object?

#

it just hides it rather than giving you a visual on a potentiall out of date actor?

prisma ore Jun 7, 2018, 9:22 PM

#

the culling is usually done to keep performance

dull stream Jun 7, 2018, 9:22 PM

#

performance for the client?

prisma ore Jun 7, 2018, 9:23 PM

#

in this case, for net culling, performance with the network and a bit for visuals

dull stream Jun 7, 2018, 9:24 PM

#

i guess what i mean is, instead of just letting the actor exist as what you have most recently seen without communicating with the server, it hides it.

#

which makes sense especially for non-static things like players or enemies

#

sorry kinda just thinking out loud

prisma ore Jun 7, 2018, 9:25 PM

#

yes, things that could also be heavy to replicate even if they are fare

#

*far

@marsh gate hey. was looking into this. as long as the code overhead is not too bad i can try it. saw they have some kind of automated downtime and dynamic instancing for diffrent times of day. i am totally fine with a ded server staying up for 24/7, just need to focus on optimization and trying to get the graphics util down to below 4GB for my dedicated server build. i am fairly certain the problem is coming from my graphics. so since i add in like tons of 4096 maps, it might be causing it. problem is i got some of my assets on the marketplace, and they were imported from other users hard disks do i dont have access to the original texture files. would be happy to manually convert everything in a batch image resizer, just need to figure how to get at all the files. if anyone else has any idea why a dedicated server build might be taking up 4.5 GB for the exe please let me know, would love to hear ideas on that. trying to get it down to under 4 GB so my ec2 pricing is halved ($40 a month instead of $99 a month).

I know there's a lot of performance analysis tools that UE4 comes with @twin juniper

#

I have never used them before, but I know it is extensive

#

Hey guys I'm trying to run my dedicated server but I'm running into this error

📎 unknown.png

#

that's such a random error, missing sky sphere? Idt I ever even touched a sky sphere

twin juniper Jun 8, 2018, 2:35 AM

#

are u talking about this stuff here https://docs.unrealengine.com/en-us/Engine/Performance . currently reviewing.

#

for that error did you fix up redirectors on the appropriate folder, and try repackaging?

#

make sure there is no dangling references anywhere to anything you might have imported from marketplace?

dull stream Jun 8, 2018, 5:41 AM

#

this is kind of a silly question, but I guess functions that arent marked specifically as client or server can be called by anyone?

#

and follow up question, if this is the case; why mark something as Client or Server instead of having if statement and checking the actors role? cleaner code?

#

nvm i did some reading and i understand it better. its more along the lines of when a client wants to call a function on server and vice versa

#

rather than determining if the code should be executed (although it does sorta do that but thats not the main intent)

marsh gate Jun 8, 2018, 6:13 AM

#

@twin juniper yup, you found it 😃 Looks like many of the performance tools are there. Regarding your case, perhaps this may be of use: https://docs.unrealengine.com/en-US/Engine/Performance/GPU

#

I have no imports from marketplace, but I'll check redirectors

the event doesnt get called

only on session recieved

this is my gameinstance

#

@thin stratus ?

marsh gate Jun 8, 2018, 6:45 AM

#

@umbral adder when is the event being called? Does it ever get called?

#

if it is the case that it's never being called, the issue is in another part of your code where the Event on Session Invite is being called

#

Not in the implementation of the event

umbral adder Jun 8, 2018, 6:50 AM

#

@marsh gate it never dets called

#

hm..

marsh gate Jun 8, 2018, 6:50 AM

@twin vault yes

Send Session Invite to Friend's implementation is what calls Event on Session Invite Received?

umbral adder Jun 8, 2018, 6:54 AM

yes

marsh gate Jun 8, 2018, 6:54 AM

Then debug that

#

Use the BP debugger

see if it's being executed properly

umbral adder Jun 8, 2018, 6:55 AM

#

bp debugger?

#

print strings?

marsh gate Jun 8, 2018, 6:55 AM

#

Play game
Go to the BP you want to debug
On the top right click "debug filter"
Select your BP
Observe red lines demonstrating nodes being executed

#

more efficient than print strings

umbral adder Jun 8, 2018, 6:55 AM

ohh ok

twin vault Jun 8, 2018, 6:56 AM

you created a party right?

i think you need one to invite at all

umbral adder Jun 8, 2018, 6:56 AM

@twin vault party?

no

just sent 1 invite

#

@marsh gate does bp debugging work with blueprints?

and in standalone build?

marsh gate Jun 8, 2018, 6:59 AM

and only works for blueprint

umbral adder Jun 8, 2018, 6:59 AM

@narrow trench HUD is probably going to be deprecated or renamed to "PlayerScreen" (according to an already-old livestream) soon. It's best to avoid it and use 100% UMG, especially since HUD doesn't add anything new. You distinguish between host and clients by using SwitchHasAuthority.

doesnt this mean that the simulated pawns will call the serverSetMove ?

#

and isnt that bad?

#

or do I misunderstand something

umbral adder Jun 8, 2018, 8:54 AM

#

@twin juniper get player controller id returns 0 right?

#

and u dint answer my question

#

waht is the meaning of it

twin juniper Jun 8, 2018, 8:56 AM

#

yes for self, i think its some kind of strange conversion or something to convert it to be used by the networked voice.

#

all i know is, that code works :>

#

i always call it from self in playercontroller

umbral adder Jun 8, 2018, 8:56 AM

#

ohh so it doenst return 0?

#

ok

#

i dont get 1 thing get player controller id retruns the net player id or local?

twin juniper Jun 8, 2018, 8:57 AM

#

just looked i think it does

#

you have to convert it to "byte" i blieve

#

believe*

#

to be used in that networked voice call

umbral adder Jun 8, 2018, 8:58 AM

#

i am unable to understand

twin juniper Jun 8, 2018, 8:58 AM

#

well

#

so if you have a player controller

umbral adder Jun 8, 2018, 8:58 AM

#

nvm

twin juniper Jun 8, 2018, 8:58 AM

#

and it can be any player

#

like player 1-8

#

ok

#

it works for me

#

when i press the button and any player tries

#

not just player 1

umbral adder Jun 8, 2018, 8:58 AM

#

with steam?

twin juniper Jun 8, 2018, 8:58 AM

#

yeah

#

i use steam online subsys and advanced sessions

#

somteimes packets drop

#

and mic dropouts

#

but it works

#

make sure to add the aadvanced session voicelines like mordentral states on his advanced sessions forum page into defaultengine.ini

#

should work.

umbral adder Jun 8, 2018, 8:59 AM

#

when u hold it activates for u only right?

twin juniper Jun 8, 2018, 8:59 AM

Anyone here have experience with dedicated server instance performance costs?

Like in personal experience, how much processing power and ram does a single instance of a typical ue4 project take up?

Trying to figure out costings of running all our dedicated servers on amazon EC2s, and how many game instances we can run on a single server instance

twin juniper Jun 8, 2018, 10:16 AM

#

@hollow patrol i've done this.

#

the process is fairly lengthy (took me about 3 days to get everything working at full blast), but once it's up, it's really fun to see working 😃 fire and forget. i use t2.large for mine, the cost is roughly .13 per hour and 99$ per month. if you use t2.medium, your ram must be below 4 GB, and you are looking at roughly half that cost per month. you should run your game server.exe with -log enabled in a shortcut to see the console, and test your ram util / cpu util on your local machine first. that way you can gauge what you'll need instance wise by looking at the process details in the task manager of your machine.

#

hope that helps. let me know if you need some general paradigm advice on setting up the dedicated server. i have a friend on here who walked me through the whole thing.

@hollow patrol i am running one server. if you try to run more than one, you will need to do some kind of port setting for it. if you run more than one you can go up to the mem cap - but just make sure to keep all TCP / UDP / ICMP open with ec2s

I actually call a server RPC to switch weapon

but that variable is replicated

I've also got a client RPC call inside the server switch weapon rpc just to make sure it's updated on both server and client

that was just for testing

Does player state have issue with running multiple instances in editor? Because my switching weapon works for one of the clients

#

and the second client seems like it uses the same state as the first client

gleaming bobcat Jun 8, 2018, 1:11 PM

Use data breakpoint then

I'm also interested in understanding how to use online beacons for the party system, but I've seen some stuff in the engine like the OnlinePartyInterface that makes me wonder if beacons are really needed for this purpose

but I guess explaining that beats the purpose of selling the party plugin on the Marketplace

ahh partyclient & partyhost

vocal dagger Jun 8, 2018, 1:34 PM

I'm right now trying to understand why beacons would be necessary for a party, I think you cannot join a session unless both client and server call their respective travels into a new map

umbral adder Jun 8, 2018, 1:34 PM

mabye

#

but what i do understand is for example,

vocal dagger Jun 8, 2018, 1:34 PM

#

so there is a lot of examples in the OnlineSubsystemUtils module

twin vault Jun 8, 2018, 1:34 PM

#

if you dont use beacons youre bound to platforms wich implement the interface, steam, xbox, psn...

umbral adder Jun 8, 2018, 1:35 PM

#

u want to dm someone but to do that ull need a connection

#

usally ull have to join the session to connect up

#

but with beacons its just simple tcp/ip stuff

#

its the base for ue4 networking

vocal dagger Jun 8, 2018, 1:36 PM

but if I do care about the platforms that implement it, is it worth it?

#

hi!

It seems to me that Net Update Frequency is different for the client and for the server

#

is that correct?

#

in my game, my pawn has a NetUpdateFrequency of 10.

#

The server sees the client move quite smoothly while the client sees the server move in a jittery manner.

#

What gives?

umbral adder Jun 8, 2018, 2:17 PM

#

steam? @daring arch

daring arch Jun 8, 2018, 2:17 PM

#

not using steam.

daring arch Jun 8, 2018, 2:57 PM

#

this is confusing: it seems to me that the server has a different Net Update Frequency

#

everything is smoother on the server than it is on the client

#

either that or the server has some sort of built in interpolation

#

any ideas?

icy nacelle Jun 8, 2018, 3:06 PM

#

Whats the best way for a player to pick up another player? Should I be doing this by mounting the player onto another and then restricting their movement input?

marsh gate Jun 8, 2018, 3:11 PM

#

Not restricting their movement input, just restricting their movement. You'd have a property like bIsPickedUp and you'd check this on every movement operation

#

You don't want to prevent players from even sending inputs to the game

#

Imo

#

@icy nacelle

icy nacelle Jun 8, 2018, 3:13 PM

#

Yeah movement is what I meant, infact I've already sorted out that stuff using a bool variable

#

I'm thinking about more on how I should deal with picking up the player

marsh gate Jun 8, 2018, 3:18 PM

#

You can attach the two pawns together

icy nacelle Jun 8, 2018, 3:18 PM

#

Yes, I'm trying to figure out how to do this.

slim holly Jun 8, 2018, 6:17 PM

#

if you're using regular character class, probably not possible

#

🤔

#

like outright attach them

dull stream Jun 8, 2018, 7:39 PM

#

picking up a player sounds difficult

#

definitely need some customized character movement

marsh gate Jun 8, 2018, 7:55 PM

#

Guys how do I make a multiplayer match for players to join

#

That's what a session is right

#

Can I make it via BP?

#

I added in some code into GameSession::RegisterServer()

#

Idk how to connect to it though

#

Or how to even see if the session was successfully created

#

How can I see if a session has been successfully created?

Thanks Victor :)

dull stream Jun 8, 2018, 8:59 PM

#

Can someone explain to me when I should and shouldnt use the custom flags in the character movement component? For example, they use it for crouch and the wiki has an example with dodge where they use it...

#

but im not understanding the benefits here. like i know it compresses the boolean with other stuff

#

but then it has to do some wacky stuff with the simulated proxy characters

#

idk its just freakin strange, and it works for me but it doesnt show the animation for other clients when i do my dodge/dash right now.

#

I know its a loaded question, but maybe someone has experience adding a dash or dodge mechanic, and maybe they know how to get the animations to play for players other than yourself

meager spade Jun 8, 2018, 10:14 PM

#

are you playing the animation through the blueprint?

dull stream Jun 8, 2018, 11:50 PM

#

yes I am @meager spade

meager spade Jun 8, 2018, 11:50 PM

#

the AnimBlueprint sorry

dull stream Jun 8, 2018, 11:50 PM

#

I am calling a getter function which gets the bool which is part of the compressed flags

#

yes anim blueprint

#

i am getting the bool in the anim bp

#

the flag gets set via client input, so it makes sense the simulated proxy wouldnt have it set. but im not sure how to set it, or if i should be using a separate boolean thats replicated

#

theres a bCrouched in the Character class that is separate from the bWantsToCrouch (which is the compressed flag)

#

so i was trying to do that but idk

#

not sure where I should set it to true/false in the whole process

meager spade Jun 9, 2018, 12:03 AM

#

the bool would need to probably be rep notified

#

and set on the server

dull stream Jun 9, 2018, 12:04 AM

#

yeah thats what i was trying to do... Im probably not setting it to true int he right place

#

but im not sure where that should happen

meager spade Jun 9, 2018, 12:04 AM

#

blueprint or c++?

dull stream Jun 9, 2018, 12:04 AM

#

C++

#

im referring to the bool on my character that is separate from the flags

meager spade Jun 9, 2018, 12:05 AM

#

how are you querying it in the Animblueprint for the dash?

#

based on the Movement Mode?

#

i did mine via a bool which gets removed then the dash is finished

dull stream Jun 9, 2018, 12:06 AM

#

no no, not movement mode. Im just getting bDashed by callling IsDashing, which is a C++ function

#

isdashed exists in movement component

#

isdashing*

meager spade Jun 9, 2018, 12:06 AM

#

so you would need to replicate bDashed to all clients via a repnotify

#

the only issue is

#

the other players dont have the animation playing

#

they move correctly and everything

#

its just the damn animation

#

i keep hearing about gameplay abilities i should probably be using that

meager spade Jun 9, 2018, 12:30 AM

#

@dull stream only thing i can think of is you need to replicate the bool

#

so all clients get it

lament kettle Jun 9, 2018, 12:30 AM

#

When I apply damage to a character, and then set the player state health..... and then do a (on-rep func) with the health being set, to show on the widget, there's a small delay?

meager spade Jun 9, 2018, 12:30 AM

#

how small is the delay?

lament kettle Jun 9, 2018, 12:30 AM

#

I would say 0.3 to 0.8 seconds

so 300 milliseconds to 800 milliseconds

@agile lotus The PlayerCameraManager class provides Server Side information on Camera Location/Rotation information.

For Clients

But typically you would not replicate a camera no, i cant think why you would outside of the default state of the PCM.

using a shared camera and was wondering if it was a good idea to replicate it or let clients do it

if its already handled by the PCM then thats good

For your game i think you should let Clients manage their camera themselves.

Is it OK to store widgets in player state? e.g. I'm trying to implement a kill feed and even when the player dies, I still want the player to be notified of deaths

umbral adder Jun 9, 2018, 4:18 AM

#

why store in widgets in player state?

#

store the kills in the player state

scenic tangle Jun 9, 2018, 4:18 AM

#

yeah I'm wondering if that's a good idea or not - perhaps there's a better way

umbral adder Jun 9, 2018, 4:18 AM

#

and bind the property

#

in the widget simple 😃

#

i have already done mine

scenic tangle Jun 9, 2018, 4:18 AM

#

but when the player is dead does he still receive updates?

#

because destroying the actor will destroy the widget wouldn't it?

umbral adder Jun 9, 2018, 4:19 AM

#

no

#

who says?

scenic tangle Jun 9, 2018, 4:19 AM

#

my assumptions 😛

umbral adder Jun 9, 2018, 4:20 AM

#

just make a isvaild in the widget

#

unless remove from parent is called

scenic tangle Jun 9, 2018, 4:20 AM

#

wait but don't you have a reference to that widget when you first create the character?

#

where are you creating this widget by the way? we might be talking about different things

umbral adder Jun 9, 2018, 4:21 AM

#

i told u to create it in hud class

scenic tangle Jun 9, 2018, 4:21 AM

#

HUD class is outdated now isn't it?

umbral adder Jun 9, 2018, 4:21 AM

#

no

#

its just not used that much

#

reason being you can use a is locally controlled bool

#

but yes its not used much

scenic tangle Jun 9, 2018, 4:22 AM

#

hmm ok thanks 😃

umbral adder Jun 9, 2018, 4:26 AM

😄

fleet sluice Jun 9, 2018, 4:27 AM

#

@scenic tangle Yes, yes it is. @umbral adder Should stop promoting it. Epic themselves said, in an older live-stream, that HUD will either be deprecated or renamed and repurposed. They use UMG in Robo Recall and Paragon. Period.

scenic tangle Jun 9, 2018, 4:28 AM

#

OK thanks for the info vlad

umbral adder Jun 9, 2018, 4:28 AM

#

hud class in the gamemode is just used to create widget's whats the harm in that?

#

instead of using a bool node and checking if its locally controlled?

fleet sluice Jun 9, 2018, 4:28 AM

#

It's the equivalent of coding in Notepad and that's it.

umbral adder Jun 9, 2018, 4:29 AM

If you want to be stuck in the past, go for it. But don't teach others to do so as well.

umbral adder Jun 9, 2018, 4:29 AM

#

so where is preffered to create widgets?

brittle sinew Jun 9, 2018, 4:30 AM

#

Using the HUD and UMG aren't mutually exclusive; like Decode said, you can use it to spawn UMG widgets. If you're using it to manually draw things shape by shape however, that's a different story. 😄

umbral adder Jun 9, 2018, 4:30 AM

#

😄

#

not going to draw shapes xD.

fleet sluice Jun 9, 2018, 4:32 AM

#

@scenic tangle Think of UIs this way: the engine was built for multiple local players. Each of these has an APlayerController actor associated. Each of them also has a screen associated, which isn't easily "visible" in BPs. Ideally, you'd create/destroy UMGs in an APlayerController subclass, because you're going to use that anyway, but HUD is just as optional as an APlayerState (sure, the engine creates all that stuff by default, but routing every single bullshit through some of those classes will just end up with a ARK/PUBG/ConanExiles-like performance).

umbral adder Jun 9, 2018, 4:32 AM

#

btw Vlad, do you know about online beacons if so could you tell me how to connect them?

fleet sluice Jun 9, 2018, 4:33 AM

#

The usual "single local player" type of game is just a particular case of what I said above and works the exact same way.

#

I know a bit. I'm not going to tell you. I read every single line that's being written in this channel and you're the kind of person who takes my whole arm if I lend you a hand. Read this: https://answers.unrealengine.com/questions/467973/what-are-online-beacons-and-how-do-they-work.html

If that doesn't work, just mention Cedrix (eXi) again. I'm sure he's enjoying it.

scenic tangle Jun 9, 2018, 4:35 AM

hahaha OK Vlad, cheers for the helpful advice

Oh I see

it's when it's a dedicated server

#

summer iron Jun 9, 2018, 1:35 PM

#

Is there any good documentation anywhere that explains how to use the networking especially the stuff that should prevent hackers/cheaters to teleport around or exploit network variables etc.?

winged badger Jun 9, 2018, 1:54 PM

#

clients can only affect the server via server RPC

#

and can only push a variable to the server as an argument to the server RPC

#

all of them come with bool MyServerFunction_Validate(params); function that you have to implement by default

#

which is, aside from some special use cases, like Server instructing clients to disable user input for a bit, enough to prevent clients from cheating

#

listen server host is entirely different subject

summer iron Jun 9, 2018, 1:59 PM

#

so I should avoid using client RPC functions when doing things that only the server should be able to do e.g. teleport players around

winged badger Jun 9, 2018, 2:00 PM

#

server is absolute authority

#

when it client RPCs it notifies the client that something in its PlayerController hierarchy changed

#

has no affect on cheating

#

client can for example hack his location, teleporting, locally

summer iron Jun 9, 2018, 2:01 PM

#

maybe ill understand it better with an example, how would this scenario secure against hackers: we have the player who needs to speak to some npc to fast travel somewhere, what kind of network functionality would you be using here

winged badger Jun 9, 2018, 2:02 PM

#

on the server, and as far as any other clients are concerned the location of the would-be cheating client will not change

#

if he does that

#

next update for the client's character, server will replicate the location again and correct him to where it should be

#

in your example

#

say player presses E key to interact with the NPC

#

that is mapped to InputActionInteract in your ProjectSettings/Input

summer iron Jun 9, 2018, 2:04 PM

#

yes, so on the server there would be a check if he is within the range of this npc

#

else it could be faked and he would be able to fast travel from anywhere theoretically

winged badger Jun 9, 2018, 2:04 PM

#

and your, say, PlayerCharacter blueprint has a node to handle that input action

#

from there you just do a ServerEventInteract, replicated to server, reliable

#

and let the server handle all the logic required

#

is the NPC in range, did the player complete a required quest...

summer iron Jun 9, 2018, 2:06 PM

#

and I would be using a UFUNCTION( Server, Reliable) void ServerRPCFunction(); for this

winged badger Jun 9, 2018, 2:06 PM

#

the name is unfortunate

#

and also, WithValidation

#

but yes

summer iron Jun 9, 2018, 2:06 PM

#

alright so in the XX_Validate function I would be doing all the checks or?

winged badger Jun 9, 2018, 2:07 PM

#

that function will just drop the client

#

if it returns false

#

so no, you should be catching cheaters explicitly there

#

and nothing else

summer iron Jun 9, 2018, 2:07 PM

#

yea that is what I meant, check if player is within range of npc and quests etc.

winged badger Jun 9, 2018, 2:07 PM

#

you don't want to boot a player if he pressed E while being a meter too far from the NPC

summer iron Jun 9, 2018, 2:08 PM

#

no but the client shouldnt send that interaction if he is too far away anyway

winged badger Jun 9, 2018, 2:08 PM

#

basically ServerRPCFunction_Implementation() should handle the interaction

#

as it if were a single player game

#

and just ClientRPC the results

#

back to the player

#

like NPC is in range, and available for a chat, you should open a dialogue window now

summer iron Jun 9, 2018, 2:10 PM

#

Alright I think I understand it now thanks

#

I got another question with this server/client thing, so basically if I want to hide some server logic for example a database connection from the game.exe how would I do that

#

the end goal is to have a dedicated server that connects to a database, and there would probably be a few things that I would prefer wasnt available in any of the exe/dll files the client needs to play

winged badger Jun 9, 2018, 2:12 PM

#

dedicated server has a separate build

#

you wouldn't need to hide it because only dedi build would have it

#

my advice: get the thing to work now, catch the cheaters later

summer iron Jun 9, 2018, 2:15 PM

#

yea sure I just like to understand things before I work with it, but how does the dedi thing make sense, I guess my question is more like how can I split the c++ code for client and dedicated server

winged badger Jun 9, 2018, 2:15 PM

#

i have not worked with dedicated servers

#

but you would have some classes that exist only on server

#

easiest example: Component of a GameMode

#

and you would not package that class, or the database with your client builds

#

(educated guess now)

summer iron Jun 9, 2018, 2:18 PM

#

yea ofc not, just wondering if I need to make a seperate module that is only available for the server incase all the c++ code is packed to 1 thing that the client needs

winged badger Jun 9, 2018, 2:19 PM

#

that i can't help you with, probably not

summer iron Jun 9, 2018, 2:19 PM

#

np ill figure it out eventually

icy nacelle Jun 9, 2018, 5:01 PM

Hey guys! I've been trying to think of the best ways to handle this, and I thought it'd probably be best if I ask here before going ahead:
I've got a jailing system in my dedicated multiplayer game. Players are sent to jail for a certain length of time, and then released. If a player disconnects, their remaining time is resumed when they return. What kind of system should I create to handle this? I was thinking of having a timer on the player controller using 'Timer By Function Name', and then pausing it when they disconnect, and releasing them when the timer is complete. Are there any heavy downsides to using a system like this that I should be aware of? What would you recommend is the best way of doing this?

dull stream Jun 9, 2018, 5:27 PM

#

my biggest concern would be about the number of players, and if players can be replaced. Lots of memory use if theres a lot of players leaving

#

I dont know if theres an alternative though other than having a database?

icy nacelle Jun 9, 2018, 5:30 PM

#

Thanks for the response @dull stream, what kind of database would I be looking at creating? I'm already using a datatable to store all the items in the game, would it be using the same datatable system?

dull stream Jun 9, 2018, 5:30 PM

#

oh i meant like, legit database thats separate from the dedicated server that has information about your players

severe widget Jun 9, 2018, 5:31 PM

#

also you can't really write to a DT

#

I'd suggest a database as well

#

There's probably an alternative if you're ok with sketchy workaround for just-this-one-thing and just-that-one-server, but that isn't a good idea unless you can't avoid it.

dull stream Jun 9, 2018, 5:34 PM

#

yeah it might be "ok" to do it that way but its definitely not a good practice to be storing persistent information about your players, even if they are logged off

#

just think about if you had like, a million players and your server executable is storing all that memory during runtime

#

regardless of whether or not you had like, 10k people currently playing

#

it would still be storing memory about all 1 million players

#

im exaggerating the situation to convey the potential issue

severe widget Jun 9, 2018, 5:37 PM

#

sure.

#

and not only that

#

but you'd be storing the data all of players who ever logged in and not finished their sentence. (assuming you store beyond server shutdown)

yeah it could be dangerous

icy nacelle Jun 9, 2018, 5:39 PM

Great, this is really helpful. I don't know anything about creating this type of database though, what's some keywords I can search this up to get a good understanding of how it works?

I have no idea. Never done it and know nothing about it. 😆

#

I see a lot of MySQL when I try and research the database, is this what I'm looking for?

dull stream Jun 9, 2018, 5:40 PM

#

so Im interested in the answer as well

#

probably would need some sort of sql backend. but idk how ue4 would communicate with the database. i know theres json stuff in ue4, and theres nodejs plugins

#

plugins to help make the process easier. but either way you'd have to have a separate server with a sql database of some sort, probably

severe widget Jun 9, 2018, 5:42 PM

#

if this is like an MMO with instancing and stuff

#

you'd have to have a database server

#

otherwise if its more like, say, Rust, you could get away with SQL on the same server

#

there's a few plugins to UE4 which assist with SQL and also doing JSON stuff

icy nacelle Jun 9, 2018, 5:45 PM

#

hmmm alright, looks like I'll have to do some research and learning 😃 Thanks for your help!

#

Would it be good to store things like inventory and skill levels on the server also?

dull stream Jun 9, 2018, 5:47 PM

#

yes, unless they are temporary and disappear when you log off.

#

anything that is persistent for a long period of time. wouldnt want the players to lose their stuff if the server crashed or there was maintenance

#

everytime you created a new server build, like when you add new content to game, youd shut down server and lose all the stuff

#

if its on a database it wouldnt be lost

@severe widget I've had a look around and decided since I'm a novice at databases, it'll probably be a good idea for me to download a plugin,

With connecting via ip do I have to write a port too?

#

Or only ip

twin juniper Jun 10, 2018, 8:25 AM

#

@twin juniper i use execute console command node -> open x.x.x.x without a port number for a dedicated connection, works.

#

@agile lotus any luck with your issue yet? the general process i use for testing listen servers with create and find session is by using two separate machines, and a steam test app id 480 in the defaultengine.ini file

unique thunder Jun 10, 2018, 8:54 AM

#

What's easier / better for replication:
a) Play sound at location
b) Play sound component in BP

fleet sluice Jun 10, 2018, 10:07 AM

#

@twin juniper If you don't specify a port, it defaults to 7777. If your server is on another port, it will fail (if you run multiple servers, they will bind to multiple ports).

I’m trying to store a var across sessions using advanced sessions and I see that player controller is passed in. I created a var called left handed in my steam VR player controller and I’m setting a local var in my character bp on possessed with it ... it seems it’s resetting?

thin stratus Jun 10, 2018, 10:39 AM

#

Your PC and the Session stuff don't really have to do much with each other

#

The PC that you pass in is used to retrieve a specific user ID in the code that the Session Nodes use

#

If you want something to persists, you either use SeamlessTravel and use "OnSwapPlayerControllers" in the GameMode to pass the data over (Server). You'd need to replicate the variable after wards of course.

#

Or if you don't/can't use SeamlessTravel, save it somewhere local (GameInstance/SaveGame)

thin stratus Jun 10, 2018, 12:50 PM

#

Hm, just to refresh my memory: Why can't I override an OnRep function in a Child of a BP?

I am getting Removed Incompatible build whenever I am trying to search for sessions using the steam online subsystem

I am running the same build on two different computers with two different steam accounts, how come I can't find my session?

What AppID?

#

@cerulean hamlet

cerulean hamlet Jun 10, 2018, 6:23 PM

480

#

I know everyone uses this

#

But I set the search results to 200000

thin stratus Jun 10, 2018, 6:23 PM

#

Soo, what do you think is "Remove Incompatible Build" then

cerulean hamlet Jun 10, 2018, 6:23 PM

#

and I still only see the same 4 sessions pop up

#

I know what it means, it's finding sessions of different binaries. But I am hosting a session from one computer with the same binary as what I am using to try and find it

#

how come I'm only getting 4 sessions when my search results number is so high?

thin stratus Jun 10, 2018, 6:24 PM

#

@umbral adder One Base Weapon class, two child classes.
Each having their own Fire Weapon Implementation, Animations, Meshes, Sounds, etc.

#

@cerulean hamlet Well, Steam uses a Presence system, means it checks for your region, friendlist, friends etc.

#

That sadly has the problem that it often fails to find session if you aren't in the same download region as your friends

cerulean hamlet Jun 10, 2018, 6:25 PM

I see

thin stratus Jun 10, 2018, 6:25 PM

And I wouldn't trust the log there too much

for a custom AppID I need to have my own app id right?

Ultimately you want your own

cerulean hamlet Jun 10, 2018, 6:26 PM

iirc, I have to apply for one correct?

thin stratus Jun 10, 2018, 6:26 PM

#

I wouldn't worry too much atm. It's only for connecting and serverlist.
You can still code all the rest of your game.
And if really needed, connect via IP (or lan session + hamachi or what ever you can come up with)

#

You have to setup a dev account iirc and pay the 100€ or $

cerulean hamlet Jun 10, 2018, 6:27 PM

#

right

thin stratus Jun 10, 2018, 6:27 PM

Then you should get your ID

cerulean hamlet Jun 10, 2018, 6:27 PM

But it seems like other people have had success with 480, I'm thinking I should also see it

is download server the only thing that matters for region?

As far as I'm aware, yes

#

or crosshair

#

i have done it but its a bit intensive i think and i want to know an optimised way

severe nymph Jun 11, 2018, 2:29 AM

#

Line trace

#

Then spawn the crosshair or effect as decal

#

On hit

#

Use hit normal to give the decal transform

#

No different than blood or any other particles you would do on hit

umbral adder Jun 11, 2018, 2:31 AM

#

what's a decal transform and hit normal?

severe nymph Jun 11, 2018, 3:06 AM

#

On hit and on overlap events

#

They return results and can break the results out

#

They have information like hit location, hit normal etc

#

Use that to execute a spawn decal node

#

Then from hit normal you tell the decal how to spawn and which direction to face

@strong breach it seems when I use a standard static mesh pawn using applied force to move the pawn the client sees all movement but the server cannot see the client move and when the server comes in contact with the client the client snaps back to its original loc and then loses all movement control =/

twin vault Jun 11, 2018, 10:33 AM

Anyone know a technique to avoid jitter on listen server? on clients i can just interpolate between the client position and the server position, obviously if i do that on the server it will have the wrong location, i though about just interpolating the mesh, while keeping the actor on the correct place, but that would cause to the physics asset to be on the wrong place

strong breach Jun 11, 2018, 10:43 AM

#

oh im using c++

#

our games are the exact same thing lol

#

but its not stuck i dont believe i think the server is just updating its position (which is just sitting there) thats why its kind of jittery

#

just guessing here but i think you need to update the simulated proxy on the server's position (which is the ball the user is not controlling on the server)

tired jasper Jun 11, 2018, 10:52 AM

#

as soon as I create a session I do ServerTravel into this URL /Game/Maps/TestMap?game=/Game/Gameplay/GameMode/FNTestMapGameMode.FNTestMapGameMode_C?listen?bIsLanMatch=1

that changes my session state, then if I don't have bAllowJoinInProgress I cannot find the session anymore

vocal dagger Jun 11, 2018, 4:04 PM

#

ok in case someone comes in here later, it looks like if you open a map after you create a session it will set the session state to InProgress, I think I can either 1. Update the session to Pending on the "LobbyMap" so that other players can find it and join or 2. Maybe I can open the map with the listen parameter and there create the session. I'm not even sure I need to open a map with the "listen" parameter, I think it's unnecessary
