Oh you want your players to remain in the party?

fresh saddle
chrome bay
yah
fresh saddle
Ah.. yeah as I said, it has no other proper functionality other than being able to all join one server and what else
thin stratus
You might need to handle that by saving who's in parties
And when the game is over you just recreate teh group my hand
or @rough iron Knows something
fresh saddle
Yeah there's definitely ways of doing it
chrome bay
Yeah the only other thing I can think of is tracking it all manually...
but would probably lose features in the process
thin stratus
You sure that steam doesn't have some kind of interface for that?
chrome bay
nah I checked 😦
IOnlineSubsystemSteam::GetPartyInterface() return nullptr;
#cry
in fact they all do, I think that party interface is for Xbox / PS4
thin stratus
bummer
chrome bay
I will hax this
chrome bay
yeah I wonder if beacons might be the other way to do it...
they're supposed to be a way to send super minimal data to a connection I believe
gonna have a look
ooo
in fact... why am I thinking about this when UT probably does it.. ugh
yep.. UT literally does everything I want
#RIP
rough iron
If you like we can chat about parties tomorrow (got a bbq in a moment)
rough iron
The idea is actually simple, and on e you know how to use beacons you can vreate aome awesoe matchmaking systems
fresh saddle
If you find something, fill me in. Been too busy to work on my hacky implementation and it'd be nice to see other solutions
chrome bay
yeah UT seems to handle parties via beacons... which is pretty sweet
rough iron
I did the matchmaking for 4 games so far (all using beacons)
chrome bay
and turns out UParty is an actual thing
thin stratus
@rough iron Srsly mate, how often do you have bbq?
It's -10° in germany ;-; let me live at your place
@chrome bay Think about something you want and put a random letter infront
UMakeGameButton
Wouldn't surprise me if that's in the engine
chrome bay
haha probably
chrome bay
ok so this party thing is definitely an engine supported thing - but jesus h christ is it a mindfuck
UParty is more accurately a Party Manager.. and you can join/host multiple parties of different types.. and each has a gamestate. Most communication seems to be done via beacons to keep net traffic / load times to a minimum
red ledge
would you mind sharing what you find here etc? I'm interested and it might help some other people
thin stratus
Yep, make us some documentation about it :D
chrome bay
will definitely do so when I work out what I'm doing :p
currently I can't run the editor when including the 'party' module, which sucks :/
red ledge
is that a bug or how it's supposed to work?
chrome bay
ok nvm got it, also had to enable to OnlineFramework plugin... ugh
red ledge
if you don't have time but son't mind leaving general comments here, I would appreciate that as well
chrome bay
yeh happy to do that
red ledge
there's so many things in this engine that you never know unless you stumble by them accidently in a chat or a forum post

Anyone know of a good tutorial for setting up a 3d scoreboard widget? I have one attached to my character but I cannot get it to update or do anything.
Anyone know of a good tutorial for setting up a 3d scoreboard widget? I have one attached to my character but I cannot get it to update or do anything.
chrome bay
really depends.. on lots of things
with a scoreboard you probably want to just update it using NativeTick
too much of a pain in the arse to have lots of objects trying to talk to it to update it
just make it pull data from the playerstates
slender cloud
I was trying to use interface bp to pull score values from targets. I tried to make it set to 0 on begin play though and it just doesnt do anything.
slender cloud
not sure if there is a special way I need to add it to my character. Right now I just dragged it in as a child componant
wary willow
Anyway @slender cloud look into event based driven umg
slender cloud
ok thanks
wary willow
I usually use Event Dispatchers
chrome bay
Not neccesarily. Score can potentially be updated in many different ways depending on what you're showing on it
wary willow
¯_(ツ)_/¯
chrome bay
Players also join and leave at anytime
Player States can replicate at different times
wary willow
And those are events...
chrome bay
And if you miss the events, your scoreboard goes out of sync
wary willow
Anyway, however you want to create your architecture is obviously personal preference
Not sure how'd you miss any of those events you just listed though
Unless I just haven't done anything super crazy complicated yet
slender cloud
current tut I followed was for a regular pc game, but I obviously cannot add to viewport in VR. all my other logic is set up. Widget componant still says experimental though if that could be the issue
chrome bay
Yeah, dunno why this is in MP tbf..
slender cloud
Shit my bad. I was trying to ask in VR. Wrong channel haha
wary willow
or vr
chrome bay
FUUUUUUUUUUUUUUUUUUU
FCoreUObjectDelegates::PostLoadMap.AddUObject(this, &ThisClass::OnPostLoadMap);
OnPostLoadMap isn't a UFUNCTION so engine just crashes
gr8
wary willow
Don't worry @chrome bay once you figure out all the bugfixes, you can try to submit a PR and wait a year or so until Epic decides to use it. Or never use it.
chrome bay
and I can't write a wrapper function cus it's private 😦
haha yeah true
oh wait nvm that's not it
`UWorld* UParty::GetWorld() const
{
UGameInstance* GameInstance = Cast<UGameInstance>(GetOuter());
if (GameInstance)
{
return GameInstance->GetWorld();
}
return nullptr;
}`
my outer is something else... dangit
red ledge
you can also wait for @rough iron to finish the BBQ
that's what I hate about UE4 tbh, I love the engine in general, but the lack or docs is frustrating
I'm sure there is some stuff only like 20 people know about
you will never know them unless you randomly stumble by someone who knows them
chrome bay
I wish it was like the Matrix... you just plug yourself in and learn the entire codebase in in seconds
20 years of code straight to the neurons
Ok I have succesfully created a Party object... that's a start
hallow shore
@chrome bay when you finish fighting against the party thing, i would like to hear how its actually work and what you managed to do with those, postmortem kind of thing 😛
chrome bay
well so far, I've got a party object working and am just hooking up UI delegates
BUT, got a funny feeling there isn't a default party interface and UT is using epics launcher online subsystem
which would suck massively
hallow shore
its UT thing?
chrome bay
well, UT is using the build in party system so I'm using that and the engine sauce for reference
fluid terrace
can someone tell me why this is not working
nocturne token
Pro-tip: Be more specific with your question
fluid terrace
oh, your right
the replication is not working
it only responds on the server not the client
sry about that
pallid mesa
ok, i'm on it, basically Epic's character movement components don't need to be replicated because they already are.
So it is not necesary for you to do the switch has authority neither create a C.E. for calling the jump on server @cerulean canyon
i already replied to you on #lounge i'm new in this discord im a bit lost yet.
fluid terrace
makes sense @pallid mesa but i kinda just want to know for using it on other instances of the project
i will just type here to not bother other people
pallid mesa
for using the jump you mean?
fluid terrace
the replication part of it is what i am intrested the jump is really just a test of making stuff replicate properly
chrome bay
yse LaunchCharacter on the server
*use
ReplicatedMovement will take care of the rest
oh wait nvm
alright if anyone can make sense of this class I'll pay them 1 million internet cookies
FOnlinePartyTypeId
oh wait
it's literally a uint32 wrapper
ffs
pallid mesa
you have to pay yourself 1 million internet cookies
chrome bay
lol
chrome bay
[2017.01.16-22.46.21:813][181]LogParty:Warning: No party interface during JoinParty()
shit
I guess that means there's no default party interface 😦
wary willow
@fluid terrace also, you might as well start learning proper naming conventions
pallid mesa
@wary willow Aside from files, i saw written in many different ways the rep nodes, what is the correct way? OnRep(NAME)? SV_(NAME)?
chrome bay
Ok so findings so far... UParty works with IOnlinePartySystem - which has zero implementation whatsoever.
The only implementation is through Epic's server system so far, which they haven't released publicly and all relies on having your own XMPP server
whatever that is...
So basically routing party functions via Steam as if it was an online session doesn't seem to be possible.
orchid cairn
pretty sure i know the answer to this one, but i'll throw it out there. is there currently a way in blueprint to access command line arguements passed in to the game? For example, if i was to run "UE4Server.exe -RunServer -Community=SixSeasonsAndAMovie" is there a way for me to access these without going into cpp?
alternativly, does anyone know that if i build as a dedicated server and do the same command as above, if the Options String in GameMode will have that info?
thin stratus
@orchid cairn "UE4Server.exe YourMap?Options1=Value1?Options2=Value2"
And the Option String should have that in them
orchid cairn
cheers @thin stratus - will test with my dedicated server build and see how we go
while i've got you, random quick question... in your ballbump demo, you implement your own collision/impulse for when the balls hit... any particular reason you didn't just let PhysX do that for you?
thin stratus
Eeehm, haven't looked into that for ages
I think I just wanted to have more control
My old examples aren't the best anymore. They work but i plan on recreating them properly
Learned a lot the past 2 years :P
wary willow
Haven't we all
heavy mantle
@twin juniper Sorry had some internet issue, yes the 24 video from Wes about multiplayer
Just wanted to know if we have something to buy on steam or if we can follow the tutoriel without buying anything :3
bold cedar
Over the past 2 years, I have never been able to reliably host or join a game session via IP. Typically, what I need to do, is attempt to host a session, and then attempt to join a session, and then re-host (At which point the other person is finally able to join my game). This also applies to the other person I am testing with, if I am to join their session. This has been the same over different computer builds, projects, and ISPs. Am I the only one?
This all being done without using a Subsystem. To join, I am using 'open IP', to host a map in listen mode, I am using 'open MapName?listen . This is also all being done using the ExecuteConsoleCommand function in Blueprints, though results are the same using the console command window. This all applies to all packaging builds. When joining does not work, the game simply does nothing, but will eventually restart the game to the main menu after a random amount of time (For both the person hosting, and the person trying to join)
rough iron
@thin stratus we got a bbq atlesat once a week (that's the one sponsored by the company xD), every Thursday at 11 AM, then ocasionally I make my own xD
@thin stratus we have about 15ºC atm
rough iron
@chrome bay just stared writing all done xD it will take a good while xD
red ledge
@rough iron you mean that you are writing on beacons and match-making?
orchid cairn
is there a particular reason why a dedicated server build has to be done from source?
rough iron
@red ledge yep, I try to make it a bit more general plus some insights in UT
@orchid cairn because there are a whole bunch of defines that are being set so strip editor condtent, editor code and client code
orchid cairn
ah 😃
rough iron
Small bianary size and stuff alike xD
red ledge
@rough iron can't thank you enough for this, if you remembered, please mention me when you are finished, this looks promising.
pallid mesa
Is there any way to make a GET http vÃa Blueprints?
rough iron
ok ^^
glad wharf
@pallid mesa : there is a plugin to use rest API in Blueprint if I'm not mistaken
pallid mesa
Well the objective was making It without plugins, i guess we will have to program It on C++ then
rough iron
@red ledge, @thin stratus, @chrome bay ok just wrote it down, still WIP and lot's of things that I have to add in the near future: https://wiki.unrealengine.com/PartyMatchmaking
pallid mesa
Great article. Ill be looking through It.
Is there any documentation out there about how to gamebridge properly between ue4 and discord?
twin juniper
@pallid mesa I recently heard about the api, assuming it's fairly new?
pallid mesa
Yes it is New
I have already chat communication Squad wise, So if you pertain to one Squad of the game you can chat with only your Squad or with everyone. The thing with discord will be creating a guild chat for that Squad.
And execute opt-in at the begining of the match for every member of the squad
But here It comes...
I know the theory
But im struggling with the practice
And also the oauth which is another factor to have in mind
I would appreciate any kind of guidance or documentation if someone struggled with It. :) It would save a lot of hours
glad wharf
Is it me or the network ticking rate is tied to the frame rate? I see that netcode ticking is inside UWorld::Tick...
fleet sluice
@bold cedar my first thought is to ask if you forwarded the ports 7777/7778 on each machine you're trying to use? (Server+clients)
bold cedar
@fleet sluice The answer is yes
glad wharf
@bold cedar : to Vlad or me?
bold cedar
To Vlad, my bad
Also, the network data could only be acted on each tick, so I don't see why it wouldn't/shouldn't be.
glad wharf
the problem is for voice data, I need minimal latency
I'm on LAN and ideally I would like to have like phone latency
dense citrus
how i can get player name of players over head ? any idea ? get PlayerName but than i see only my name over all players 😄
thin stratus
@rough iron awesome :O thanks a lot
fleet sluice
@bold cedar sorry, got busy for a while. Did you: 1) use cmd with "ping ip.adress" 2) use a port scanning website/program, to be 100% certain the connections outside Unreal work fine?
red ledge
@rough iron just read the wiki, thank you. I'll try to turn the lobby I have into a party session instead of just having a map in the game session for the lobby and another one for the game -if I understood correctly-
rough iron
nice it was helpful ^^ There is still a lot pending, for example ensure to cleanup your current state when you swap from serching to hosting
but the idea is actually simple, you just hold two set of sessions plus beacons
you can even hold more but it depends how and what you are able to advertise
even if you destroy a session and recreate it you shoudl always publish your uniqueid, so that others are able to research for your sessions
thin stratus
Can you make sure, when you go over the text again, to clear up some of the later stuff about having multiple Hosts together?
I got the part of searching and hosting with the PartyBeacon
And having the (non listen) party session
But when you went into having Hosts join non-complete party sessions, i lost it
rough iron
ah ok, think of it as you just create a party session, set it state to hosting
the state is just data in the sessions settings
so other start joining
once the party is full we do not have any listen server set yet
so what you do is to start another one
the game session
and you set it to hosting too
so others start joining
thin stratus
6 Players per Team
Host1 on Port 7777 HostBeacon | 2 Clients joined with their ClientBeacon to Host1
Host2 on Port 7777 HostBeacon | 2 Clients joined with their ClientBeacon to Host2
Na it's more about this stuff
Where you have more than 1 party
and combine them
rough iron
ensure to use different ports
thin stratus
And THEN join the final game session
The constellation above is not yet joined together
rough iron
7777 party, 7778 game
thin stratus
What I understood was
If you have 2 parties
with each 3 players
and you want to join then
rough iron
yep
thin stratus
Would you do that with another Host and Client Beacon
rough iron
that's the idea
thin stratus
Or is that handled by a MasterServer that just found both teams and gave them each their game session URL
Ah okay
rough iron
no, you create a new set of beacons and sessions
the game session
which all join together
on the previous party leaders (from the party beacon session) is set to host
so the other leader just send all it's clients the connection data to the new game host
and all travel together
but all have still their party beacons running pointing to their previous partyleaders
that way if you disconnect or finish you just go back where you where
thin stratus
Okay who manages this new set of game beacons
Like who puts two 3 Player teams together
thin stratus
Ah okay
thin stratus
Well take something like Overwatch. Where you team up with 1-5 Friends
rough iron
in a free for all game you mix them
thin stratus
And it matches you with other teams of variable length together
rough iron
exactly
thin stratus
so at max it could be 3 hosts with 1 client in their parties
rough iron
that's on to the game to decide how to handle it
exacly
if you see it like a venn diagram it's easier to imagin ^^
thin stratus
Na it's more like: Let's say we have these 3 parties. Each has a Host and a Client.
We are currently at the point of them only having the party session and a Host and ClientBeacon.
The 3 teams don't yet know about each other.
Now they start searching, all 3 at a time.
How do I merge them together for the game session?
Do I let them join the game session until it's full?
Do I fuse them into 1 game session with beacons (how? Which one of the 3 parties is the host etc?) and if they are full I let the "main host" search and pass the data to everyone?
rough iron
ok so we have 3 parties that already made the first part of creating those right?
thin stratus
Yes, each party has a Host and a Client, connected to each other in a party session
rough iron
so they are connected to 3 different PartyBeaconHosts
thin stratus
Yes
thin stratus
yes
rough iron
if there is nothing hosted all will fail and they will search again or start hosting
thin stratus
1 second
rough iron
there is the important part of the random, you have to make it a bit random to decide to search again or to start hosting
thin stratus
What kind of ServerModel do you have in mind here: Are they searching for DedicatedServers, that might have been hosted by me (similar to Blizz having their servers and Rocket League)
rough iron
but using a new set of beacons
thin stratus
Or will one of the 3 hosts end up as a listen host
rough iron
you will just have 1 listen server at the end, you do not need a listen server to advertise a game on your master server
for example you can call CreateOnlinegame without beging a listen server
it's just data that is in the backend
thin stratus
So the Search Part that the 3 indipendent hosts start, is not for the final server to play on, but for other teams to create a full group?
rough iron
yep
rough iron
once you have the teams ready all hosts will start searching
for a new type of session
the game session
thin stratus
Yes, so one of them starts hosting before the others do
thin stratus
so you don't end up with 3 hosting sessions and no one searches
thin stratus
Okay, let's say HostA ends up hosting and HostB and HostC find that now
What exactly happens then
thin stratus
(It's still all beacons, right?)
thin stratus
So now you are at the point where you have the venn diagram
thin stratus
Where PartyA, B and C have their part and they are connected to the game session
rough iron
we had A,B and C
let's say C starts hosting
and A and B finds C's session
A and B sends a new reservation request to C (all using the new set of game beacons)
let us say that the game mode is for 3 teams and 3 players per team
and all parties have 3 players
thin stratus
Okay, at this point, cause our example allows it, every reservation succeeds
rough iron
exaclty
all fine an full
now you may just add a timer to start the travel process, it's actually prittuy simple
we now that C has a game session
so all what we need to do is that C sends an RPC to it's client beacons and to A and B to start traveling to his session
in turn A and B when yhey receive that request from C they just forward the request to join C to their own clients.
once lil note
when C starts hosting it's own clients have to join the game session too
becasue they will be always with him
thin stratus
Okay, one sec again. so before that RPC goes off, we only have a Beacon Connection.
After the RPC and the joining, we have a correct connection like we normally have, where (if you forget about the beacons for a second) every player is connected to the host of PartyC
party session stays in tact, as we want to recreated (or keep) the parties for after the game
rough iron
After the RPCs (C->[A,B,Cs clients] B->[clients] A->[clients])
exaclty
so just after all those RPCs every player will be in the game session of C
there is where you actually start the travel to C
for the game session
so for a client of A
it's party session host is A while it's game session host is C
thin stratus
And the clients of C can actually be in the game session of C AND in the party session of C?
rough iron
yes
thin stratus
That's cool :O
thin stratus
Steam does support having these two sessions at a time?
Or do they have some special cases
rough iron
you can create more than 2
but only 1 lobby session (lobby is a steam type)
and only one can be advertised atm
so have to switch between them
recreate stuff and so
but yes you can
xD
thin stratus
So only advertising needs to be switched
rough iron
yep
thin stratus
A HostBeacon can, while having clients, switch the advertising state
Do I actually need to name them "game" and "party" or can I have my own names
rough iron
the host beacon is just a socket you use to maintain the mesh
you should name them using those
they are hardcoded
thin stratus
good to know
pallid mesa
Are we on a steam enviroment or just ue4 Enviro?
rough iron
that's so that UE creates different session types depending on the name
UE4 env for now
every platform needs it's small teaks after it
for example when you start the travel
A travels to C
thin stratus
Steam only the advertisement thing or is there something that is even more important?
rough iron
what do you mean?
thin stratus
Does Steam need some more changes to the Logic than swapping the Advertisement State of your session?
Or would everything else of the UE4 environment apply like we discussed in the example
rough iron
irrc you only update your settings
I had some engine changes to actually swap stuff but it's just for convinience
keep in mind that when you search you apply filters
so can search for lobby sessions with state needsplayers
or needsplayers is the number of players needed
that way you can even merge them better together
and make the cyclkes you like
that's on your own imagination xD
for example
I have my party with 2 players and I host
I still need 8 players to join me
so my needplayers is set to 8
there may be another party with 8 players which is searching
so that searching party might just sort their sort result to find parties with 2 players in need
it finds me and booom I got a 10 player game xD
the basic idea remains, you group all together in search/host cycles
the two session system is just there to be able to go back to your initial party
in Gears3 (no idea if it's the same in 4)
you create your party host in the main menu
so your mates can join you there
and then you just search to fill up the missing spots
thin stratus
What kind of information sharing does the beacon system allow?
pallid mesa
All this stuff related (steam, party system, HTTP requests), do ue4 have plans to make it easier to Blueprints scripters So they dont need to go through C++ or you think that would not be posible
thin stratus
Can I easily display information of everyone in the lobby to the others
rough iron
You can customize it with your own RPCs, that's what UT does
so you can share the data you like
thin stratus
RocketLeague, for example, shows the cars in the main menu of your friends if they are connected
So it's basically the typical 3 RPCs
And the Server probably has events that trigger when someone joins, or?
rough iron
@pallid mesa no idea, making it easy is hard xD because it's advanced
thin stratus
It#s still an authority based system inside of the party, right?
rough iron
@thin stratus exaclty, while the cars in rocket legue is someting different
in steam you can set data per player, and others can read that xD
in live/psn you set extra dara in your player state
so you just decode/encode what you want
thin stratus
So the party host shares the steam ID to the clients and they download the data from there?
rough iron
the party host has the steam id of the owning player
the cars list in rocket legeue is not done using beacons
it's just data of the player state steam sets or retrievs
thin stratus
No but the BeaconClients need to know about the other BeaconClients
So the BeaconHost needs to share the list of Players at least, or?
rough iron
you know your friends so you can requst it from the friendlist
yes you got that info
every time someone enters/leaves
you get it upadted
you know each other
thin stratus
Does a BeaconClient know other BeaconClients without me sharing anything by hand?
rough iron
you get their uniqueid, you could open their profile
send friend reuqests
yes, it's there by default
thin stratus
Oh cool
rough iron
all joining/leaving error ghandling is there
out of the box
the nice thing is that's faster and saver than using UConnections
thin stratus
Then just one last question, Steam related:
I know Steam has 2 clouds. A Global Game one and a Personal Game one.
Where would I store the Data of the selected car so other can use the uniqueID to fetch that?
rough iron
I think when you advertise your player state you could set it somewhere
or when you connect to a host beacon you just create a new RPC to senbd that info to the host
thin stratus
PlayerState != the one of UE4 ,or?
thin stratus
:D okay, freaking names
thin stratus
Okay cool! Thanks a ton for all that information. That's enough for me for now. Make sure to pin your Wiki once it's fully build
And I will check if I can add something to it when I have time (code examples or diagrams)
rough iron
^^ cool xD guess a lot of the conversation can be added xD
thin stratus
Yes, I think a lot of this can be packed into one venn diagram (as you said) and a flow diagram, that shows the steps from searching to later combining the sessions
rough iron
yeah ^^
rough iron
also keep in mind that I left a lot out, for example splitscreen
you may already have some players in your party
you may decide to make functionality to not go back to the original party
because your game is different in pace
it's a very game specific topic
pallid mesa
What i was thinking for the party system is having a counter for the party members and look only for matches with good to worst ping with N empty spaces in one team
But thats the easy part.
rough iron
there is a lot that you will need, and do not make too much at once
The random part is often left out
and it is a vital part to make working properly
there are a lot of simple things that are very good to take into account
pallid mesa
Im seriously thinking about building some state and sequential diagrams
rough iron
in our first iteration try to get the search/host cycle stable
using only simulations
an excle file should work xD
thin stratus
A really basic system that only matches parties and then joins a game is probably already a lot of code, but having an example that doesn't have game specific things would be usefull
rough iron
so you know how many players do your system need to be usable
thin stratus
That's why I have a private project on github with fundamental Session code
rough iron
I would love to be able to just pickup my previous code xD
thin stratus
ShooterGame is a cool thing, such as UT, but it's so much extra code that one doesn't need to start
pallid mesa
I always say thanks to UE4 for creating UT
thin stratus
Not yet looked into it, as I didn't need something from it, but yeah the open code is awesome i would think
@rough iron Always surprised how much freaking stuff you know about the multiplayer things
Epic should just put your brain online for theri documentation
@chrome bay Will love you for that information i would guess
pallid mesa
I was really impressed because is all about self researching i wish i had time to mess a little bit more with all those specific aspects of the engine, ill start building as soon as i have my ideas clear maybe i'll ask you/contact you in a while, thanks for the article It really helps out @rough iron
red ledge
that's a lot of informations. thanks @rough iron ! I'll look at it later as well, do you have a problem if I mentioned you later for some questions?
I have too many weird hidden things that I'm trying to understand how to use in the Engine right now but I'm very interested in multipler things as well.
wary willow
OPness has occured from 8am on here
rough iron
@thin stratus, @pallid mesa, @red ledge thanks ^^ atleast all those years served for something xD
@thin stratus or they just hire me xD just kidden xD I actually sarted all the matchmaking stuff when Phsyonix was working on Bulletstorm for the PS3 using GameSpy (RIP) and I had a lot of chats with Corey Davis which was in charge of their solution xD so we ended up sharing a ton of stuff on the old UE3 mailing list
thin stratus
@rough iron Awesome, should always make sure to pass knowledge on
Why reinventing the wheel :D
rough iron
yep ^^
chrome bay
Ah hey guise
Looks like I have some stuff to catch up on...
I was looking at party system yesterday - unfortuantely there's no default interface for IOnlinePartySystem - so I'd have to write my own, which unfortunately means direct UDP socket stuff
which I've a) never touched before and b) still results in disconnets when you transition to a new game. The latter could easily be solved I think but the problem is I'd have to write my own party system that supports voice etc.
Epic's system for UT4 actually uses an XMPP server hosted by Epic services - but that would cost and I'd be even more useless trying to set that up probably, especially given that UE4's XMPP system has no voice support built in.
Either way, going to be a hefty amount of work to use the Party system - which is a shame because it looks really solid.
native moth
Just a general question. Spawning of a pawn on session connect, which kind of blueprint would you guys handle that in? At the moment Im using GameModes but it seems like the "Begin Play" only fires on server start, and not when a session has been joined
brittle sinew
You'd want to use the GameMode, yes. But you should look at how the flow occurs when someone joins
You wouldn't want to use BeginPlay
thin stratus
@chrome bay Didn't really sound like you need that stuff based on what @rough iron said.
You are basically using the Sessions System for this as far as I understood
But instead of hosting a game session and starting a listen server directly, you are starting a party session
and work with the beacons
And Steam supports that out of the box
chrome bay
So basically my wierdness is that I want a persistent 'party' that can be set to 'Invite Only' or Private etc - that your friends etc. can join. You then join that and the party hosts chooses what the party does.
The difficulty is when is comes to 'hosting' a session - I want players to be able to host a session that other public players can then join - but this 'session' is a secondary lobby of sorts, and whoever is the host of that session chooses the gamemode, the game rules etc. Once enough public players have joined said session (all players can talk to each other here) - they then transition to the 'in game' session which is the match itself - but when the match finishes, ALL players in the match should return to that lobby.
brittle sinew
@native moth unfortunately, most of the functions that AGameModeBase use aren't exposed to BP. So completely overriding the default flow would be really tough only in BP
chrome bay
The idea being that once a game is over, then can choose to do another one if they wish
chrome bay
ok that may work then
native moth
@thin stratus @brittle sinew Thanks for the heads up. Im looking into OnPostLogin... No idea how that missed me 😃 Thanks guys
thin stratus
You start a party session, not with listen but only advertised. Others can find that by searching for other party sessions
This is done with the Beacons
So the connection for the party is made through beacons and persists
The host of that party session beacon then decides what to do
Searching for games for example
The rest is described above in our discussion
They bascially have thier party session and then the host of that searches for game sessions
If they can't find one after x tries (randomly) they will host a game session in addition the teh party session
And other can join etc. The join process then is the HOST joining the GAME session of another HOST
still with beacons but on another port
so the party runs on 7777 and the game session stuff on 8888
chrome bay
This may just work you know
thin stratus
It sounds really solid
chrome bay
I'm hoping a 'party' can do voice chat with each other etc.
thin stratus
That might depend on how Steam handles that stuff
rough iron
If you use steam you can use steam for it
chrome bay
YOu know what's annoying? Spending all of last night looking at the party modules and implementing stuff - only to find tghere's no default implementation lol
chrome bay
for VOIP?
rough iron
Yep using steam voip
thin stratus
Yeah the players in the party session know each others uniqueID
chrome bay
basiclaly I wanna mimic Gears 3 system - without having to have XMPP as a go-between
wanna have engine handle it all
thin stratus
which you can use to setup the voice stuff of steam
chrome bay
yeah, I should build my chat into it as well since both text chat and speech persist all the way through
rough iron
Gears3 is exactly what I described (in essence xD)
You just start your party in the main menu
chrome bay
yeh exactly
that's basically where I got to last night - until I got the log error IOnlinePartySystem: No interface found
thin stratus
Might be that the word Party is loosely used for different things
I would try the Beacon solution. Sounds pretty solid
chrome bay
I was following from UT, but as it turns out UT uses XMPP on epics backend so that's no good for me
yeah definitely
beacons it is
thin stratus
Yeah they don't use steam or any other subsystem, so they need to have some server in the backend
rough iron
They have their own
thin stratus
I mean
You can probably learn how to create your own from checking out UT
although you are missing everything outside of the UE4 code
which might make it pretty annoying :D
native moth
Another funny question. Does GameInstances merge when you join another session? I have some variables stored in a game session that decides which pawn to spawn. However when my client joins my host, it changes variables to fit the servers
I might have to move that my playercontroller instead I guess
chrome bay
Game Instance behaves differently in PIE - it's a singleton, so both instances share the same game instance.
Unless you run without bUseSingleProcess checked
thin stratus
THAT I don't know
native moth
I have the same problem when running 2 instances using "Launch Game" on the project file. But that might have the same problem?
rough iron
I'm currently writing our own OnlineSubsystem for the company, so I hope we can start with new stuff soon xD
thin stratus
@native moth Depends on what the problem is
native moth
That would also explain why one of my instances randomly freze
Well.. Atm the moment when my client joins, it gets the same pawn as my server, is should however be different
2 sec, let me get some screengrabs for you
thin stratus
So you select the Pawn in the MainMenu (non connected)
and want to give that to the Server?
After connection?
native moth
yes
thin stratus
If yes, then the Server needs to ask the Client for it
native moth
Arhh okay. So that needs to be done with an RPC?
chrome bay
actually scratch my last- im not sure if that's the case with the GI anymore
thin stratus
Yes, with RPCs
You Client has that Data saved somewhere persistent
either in a SaveGame or the GameInstance
chrome bay
but there was an issue with PIE vs standalone that screwed with our instances
thin stratus
When PostLogin gets called, you get the PlayerController of that person
So you can call a ClientRPC on it
in that get the GameIsntance or the SaveGame
then call a ServerRPC and pass that data back to the Server
Which then spawns your pawn
native moth
Okay. So I just need to figure out how to reference the PlayerControllers assigned GameInstance from my server?
thin stratus
The ClientRPC brings you to the Client version of that PlayerController
if you call "GetGameInstance" in that RPC, you will get the gameInstance of that very client
You will then get the Class or what ever you saved in that GameInstance (still on the client) and pass that to the Server via ServerRPC
You'll not reference the clients gameinstance on the server :P
native moth
And that is what buggles my mind, as you probably already can tell, I am new to this. So the ClientRPC would be an event that is set to run on client only?
or a function
Anyways, I will fiddle around with and read up on some documentation 😃
thin stratus
You have a custom PlayerController class
In there you create CustomEvent
And that is RunOnOwningClient
And a second one which is "RunOnServer"
The Second one should have an input as you want to pass the class or so back to the server
chrome bay
Something I do, if it's any help
thin stratus
@native moth Make sure to read my PDF (pinned to the thread) that should help :P
chrome bay
I store the pawn that the locla player wants to use in the playerstate. The client basically chooses their pawn, and sends the pawn 'class' to the server via an RPC.
native moth
Will do @thin stratus. Thanks for the pointers! It helps a lot 😃
chrome bay
The server then sets a var on the player state to that pawn, and replicates that back to the client. When it spawns a pawn for a player, it checks the playerstate to see which class of pawn it should spawn - instead of spawning 'DefaultPawn'
all the RPC's are handled by the player state then, which also means if you want to - clients can know what other clients are spawning as as soon as 'PawnToSpawn' is replicated
also 'PawnToSpawn' rhymes so it's kewl
thin stratus
I don't use the PlayerState for this as I can't be sure it's valid (despite using its own BeginPlay) when OnPostLogin is called
But I know that the PlayerController the he gets passed is valid
that's why I have the RPCs in the PlayerController
chrome bay
Ah yeah in my case players are spawned latently not straight away
and they choose their pawns in the game rather than the lobby in my case
the server just picks from a list of 'allowed' pawns for the game and clients can choose from that list
thin stratus
Yeah then you can fiddle with the PlayerState
As you probably also use that to display the selection to other players
native moth
it seems to be working. Will return shortly with results! 😃
chrome bay
@rough iron can you have party sessions that are 'invite only', 'friends only' and 'public' etc? i.e. advertised in different ways or is that something I'd just have to code in myself?
thin stratus
Guess you do that with parameters
red ledge
@chrome bay let us know if you could make the system you have in mind work with Beacons
thin stratus
I mean
chrome bay
Shall do, if I pull it off I'll upload sauce
thin stratus
Parties are kinda meant to work via inviting them
So I guess you only join them via invite anyway?
red ledge
btw guys, any idea how to make serverlist update in realtime without refreshing it on a timer or something?
chrome bay
I think you have to do it with a timer, I don't think you're able to poll steam servers every frame etc since it's an op that takes time
native moth
ohh well, didnt work.. I have will to run some additional tests when I get home. Thanks for the help so far 😃 I will remember to read your PDF cedric
red ledge
that host immgration sounds cool, gonna have a look at it later as well
saves you a lot of pain in the ass
chrome bay
I don't think it restores game state or anything, but then again Gears 3's never did either - just restarted the match
red ledge
yeah, I thought that you can kinda update at least the sessions you have results of on tick instead of asking for sessins again
fiery cedar
preserving score is what 99% of people will care about in any arena shooter
chrome bay
yeah. score / accumulated items would be enough probably. probably a way to reinitialize a game based on the last recieved gamestate condition
& playerstates etc
chrome bay
sweeet
man my code was so neat last night as well, hate tearing out neat code haha
@rough iron so the part I'm confused about... do I start a game 'session' or no? there's like five differnent beacon classes in the engine atm. Lobby, Qos, Party, Online, LAN, Test etc... not sure where to begin
rough iron
Qos is mainly for searches, in live there are differences
Lobby and party is very similar while lobby is a steam specific session type
fiery cedar
so for lobby migration, I've got a question
Is it for like, a peer to peer type of connection or from one game lobby to another?
chrome bay
host migration you mean?
fiery cedar
yeah, my apologies for not getting the terminology right
chrome bay
Ah ok
Basically it just means that if the player that's hosting the session drops - usually all players will return to the menu etc. In this case, a fallback client is chosen to be the new host, and all the clients are told 'who' it is - so in the event of a connection loss, they all try to connect to that new player (who hosts a new session).
the idea being you don't have to go through the matchmaking process all over again
chrome bay
haha :p
fiery cedar
Yeah, I understand that I just didn't know if it was for a p2p sort of connection. Sorry lol
chrome bay
Oh I see, nah no P2P in this case
fiery cedar
Ah
chrome bay
UE4 still uses server/client everywhere
but the clients then know what IP address to try and connect to for a session if their session suddenly drops out
rough iron
@thin stratus copy past the whole thing ^^
fiery cedar
Yeah, I'm aware of that. I just didn't know what you were referring to in this instance is all 😛
thin stratus
@ancient pebble Really need searchfunction and history xD
chrome bay
I actually did copy-pasta into a notepad doc :p
fiery cedar
so if you're doing host migration, I assume the new host would already have most of the data, would he have all positions or would the clients that are being directed to him have to send position, score, etc?
chrome bay
So long as you store everything in reploicated classes (player state / game state) - you could use that data to restore the session as close as possible
but clients don't know about other players, they just know about their pawns - so the client couldnt restore players to their pawns / pawn state etc easily
fiery cedar
so if clients don't know about other player locations (obviously a good thing to prevent cheating) would the clients upon connecting to the new host be able to send their previous data or would that just not be considered due to the fact it's probably not great to trust the info a client sends
sorry if I sound like I'm repeating myself, I'm honestly just really interested by this because I didn't realize that pawns out of sight weren't networked at all
native moth
@thin stratus YAS! Reading 10 pages of your PDF made everything clear and two simple small fixes made everything work! Thank you very much 😃
brittle sinew
I might be wrong here, but I believe that games like COD that do host migration only do it when the host gracefully leaves
So it has a chance to send info
thin stratus
@native moth Awesome (:
fiery cedar
That sounds like a good way to do it
native moth
now I got VR and a normal spectator pawn up and running
brittle sinew
Yeah, so the "exit to menu" or whatever button wouldn't do it immediately, it would handle all of the coordination for the other host
I was talking with someone about this a few weeks ago I think...I'm not sure there's a way to reliably handle host migration in the event of a crash or ALT+F4 or something like that
Without using an external master server...but then again the info would still be somewhat late
rough iron
Using beacons enables you to choose a new host (you could implement a two phace commit protocol) when the old one dies.
brittle sinew
Would that let you transfer all necessary info over though? I wouldn't trust whatever info a client has at the time of the transition
Especially like jooni said, if something isn't marked as relevent they wouldn't know about it
fiery cedar
Server/Host would know everything, clients would only likely know what's relevant as far as I know
rough iron
If you are worried about trolls a good thing regarding the beacon system is that you do not know who is the actual host. Of course you can know it by checking the amount of net traffic but thats another story.
chrome bay
when unreal crashes your PC so hard you can't restart :/ jezuz
rough iron
Networking ^^ windows does not handle lingering resources too well xD
Like not releasing a socket properly xD
thin stratus
Just rebind it until it works
dawn glen
does anyone know why when i package my dedicated server and run it if i run a standalone game client i cant move when i join it. If i play from editor and join it actually deletes and actor from my map in the editor permanently
if i join as the compiled game i cant move, if i run standalone from editor i can move
dawn glen
4.14.3
dawn glen
i have an actor that controls day/night
if i join from editor POOF
that actor is gone forever lol
wary willow
@dawn glen Please go here now: https://answers.unrealengine.com/questions/549320/4143-loss-of-player-control-in-packaged-game.html
This mofo thing is a bit hard to replicate, I thought it was a UMG issue
I'm not sure, but please post your problem there exactly
dawn glen
its wierd cause if i run a standalone from editor its fine.
wary willow
Yeah it's because of how the compilers are under the hood
they are completely different
So, I wasted over 6 hours looking over code
Because in editor it was fine, but packaged was not.
dawn glen
i made soem changes and rebuilding, will see what happens
no change
thinking its because i set uimode in the main menu level and that is persisting across to the play level.
that is exactly what it was
solved
this is interesting though... when a player logs in every player gets a copy of his UI lol http://prntscr.com/dx2gu9
wary willow
@dawn glen interesting
dawn glen
must be because i get player controller at index 0? everything i read said the local client is always 0
wary willow
Oh
Yeah, don't do that
While true, you should get it from PlayerState
So
PlayerController (0) -> PlayerState = actual player
dawn glen
im about to give up for the night i think. If i play in editor with dedicated server checked it deletes my day/night manager from the level completely forever then when i readd it it bugs the variables out so i cant assign the skysphere to it unless i restart. i never had these issues with 4.11
dawn glen
nope even restart and the variable is broken. thanks for the help. i might be done with unreal
at least until the sort this crap out
wary willow
@dawn glen going back to Unity?
wary willow
I didn't mind deving on Unity, except for its archaic UI
dawn glen
i have a UI bug where when i move a widget its broken forever
wary willow
But, I don't know, I love Unreal too much
I just wish they spent more time on the engine than their games
dawn glen
this deleting actor that makes no sense
i like UE way more than unity, i just never had these issues with unity.
then again i never had these issues in 4.11
wary willow
To be fair, 4.13/4.14 were crapshoots
4.13 was pretty decent though
4.14 was shit
4.15...well we'll see
Maybe people will be too distracted by material editor reroute nodes to notice
pallid mesa
I have that problem aswell since 4.14 release @wary willow
I checked out in 4.15 preview and It is not happening
The thing with It is if i spawn +2 players on MP the third (forth, fith...) client may not move.
It is happening aswell in editor
orchid cairn
can i ask a general question regarding multiplayer... what is considered best practice for moving data around during a ServerTravel, specifically player related data? store it in player controllers and use the OnSwapPlayerControllers event? or storing in the local gameinstance and accessing as needed (with server setters for replicated data)
rare cloud
@red ledge, No it doesn't call on the server side, but if you need to execute the function on server side you can call it manually after you change the variable
and it will be call on server side
orchid cairn
OnRep is great for UI stuff and things like that
red ledge
oh yes, I used to just set stuff manuallly, I think calling OnRep manually is much better
does it get called on the server if you do it on blueprints tho? saw some blueprints code that looked like it didn't call it on server but It's important for the logic to work?
thin stratus
There was a difference between BP and C++, yes
Can't recall if it was about Multicast or OnRep
One of the two is not called on Server in C++ but called on Server in BP
or something like that
red ledge
most likely OnRep
orchid cairn
multicast is called on server for BP fwiw
orchid cairn
is it safe to assume that the BP event OnSwapPlayerControllers will fire before OnPostLogin? and will both fire after a ServerTravel?
thin stratus
OnPostLogin fires after ServerTravel
Never used OnSwapPlayerControllers
You could check the source though
void AGameModeBase::HandleSeamlessTravelPlayer(AController*& C)
{
// Default behavior is to spawn new controllers and copy data
APlayerController* PC = Cast<APlayerController>(C);
if (PC && PC->Player)
{
// We need to spawn a new PlayerController to replace the old one
APlayerController* NewPC = SpawnPlayerController(PC->IsLocalPlayerController() ? ROLE_SimulatedProxy : ROLE_AutonomousProxy, PC->GetFocalLocation(), PC->GetControlRotation());
if (NewPC)
{
PC->SeamlessTravelTo(NewPC);
NewPC->SeamlessTravelFrom(PC);
SwapPlayerControllers(PC, NewPC); //////////////////////////////////////////////////////////////////////////////////////////////////////////
PC = NewPC;
C = NewPC;
}
else
{
UE_LOG(LogGameMode, Warning, TEXT("Failed to spawn new PlayerController for %s (old class %s)"), *PC->GetHumanReadableName(), *PC->GetClass()->GetName());
PC->Destroy();
return;
}
}
InitSeamlessTravelPlayer(C);
// Initialize hud and other player details, shared with PostLogin
GenericPlayerInitialization(C);
if (PC)
{
// This may spawn the player pawn if the game is in progress
HandleStartingNewPlayer(PC);
}
}
Put /// across the line where it gets called
And HandleSeamlessTravel gets called after PostSeamlessTravel
So I assume it gets called after ServerTravel
Let's see if it gets called before post login
Ah, of course it's a bit more brainwork to see where the calls go
-.-
Seems like PostLogin gets called by the LevelActor
HandleSeamlessTravel and PostLogin both call GenericPlayerInitialization
Can't say a lot more. Doesn't seem like it's directly visible what's getting called first
Might need you to simply test :x
orchid cairn
i'm doing that now 😃 one thing i did notice, for connecting to my dedicated server build i'm just using "open address:port" as a console command... it looks like OnSwapPlayerControllers doesn't get called there at all, as it's not seamless travel
thin stratus
Hm, isn't Seamless Travel a Server thing anyway?
I really need to setup test scenarios with it..
And with "Server thing" i mean isn't that more for travel while already being on the Server?
glad wharf
if I'm not mistaken seamless travel allows server to tell client to change map without disconnecting them
On my side I'm struggling with voice channel ticking rate, I don't know how to increase its rate to reduce latency
red ledge
@glad wharf VoiceNotificationDelta=0.2 in DefaultEngine.ini?
under [OnlineSubsystem]
I saw @nocturne token use it in his guide, might be it.
glad wharf
@red ledge : Mmmm, from what I saw in sourcecode it's used for the firing of delegates "Start/Stopped talking"
There is also NetServerMaxTickRate and PollingIntervalInMs but I'm not sure it does what I need, because it does not seem to impact on VoiceChannel packet sending rate (but maybe I misunderstood something in the code)
What puzzles me is that the TickFlush() method of the NetDriver is called by UWorld::Tick() so for me it means that it's tied to framerate, but it seems unlikely that it is the case. Would be very strange if net speed was tied to framerate !
So I will continue testing these variables but it would be better if I could understand the process behind, if someone knows it 😄
orchid cairn
@thin stratus yeah, it's after you're connected to the server
so say for example you load the dedicated server into a lobby map, you have all clients connect, choose settings/weapons etc, then seamless travel into the game map

Any tips to do with CharacterMovementComponent Ability before I try to copy the stuff from this page? https://wiki.unrealengine.com/Authoritative_Networked_Character_Movement
rough iron
If you need just biped movement use the base CharacterMovementComponent or just ensure your Pawns are base don ACharacter
ahhh ok for abilitties xD the tutorial is a goof starting point
native axle
I had huge issues on client-side when dashing at high speeds (~800 walk speed) with 200 ping. I think this is the correct way to fix it? As in having to use a custom movement component and movement abilities.
Might write a tutorial if this works well, since I've found nothing on this until today.
rough iron
Using a custom MovementComp and custom simulation is the way to go
but it requires also skill and good amount of work ^^
a vital part is prediction (for the client side simulation) and network optimizations
what do you really need to send over? How can you compress it? etc
native axle
Currently I am playing an anim montage with a custom curve. The character will move forwards based on the curve value. Not sure if this was the right way to do it, so I'll try doing the boost dodge in too.
Gonna have to think about compression a bit too, never had to deal with that.
native axle
Hmm seems a lot more complicated than I thought, better start with sprinting 😆
rough iron
ok, if you use a montage you got kind of a special move
and you have to sync the whole animation
and simulate it
what you do normaly in that part is to drive the main animation and the action in the server, while playing the animation in each box separatly but syncing the time in chunks
so you might get out of sync but not that much
if you need some precise ability movement such as in a fighting game it all get's more complicated
you have to predict a lot more, you have to know at which rate the server will play it, and compensate round trips
even then you still have to add sync steps that will just refresh all that
too many sycn steps will increase bandwicth while to less will produce hitches
xD
eternal anchor
how do I get blueprint graph (UBlueprint*), from UObject ?
dawn glen
open the object in the editor and click the open full blueprint editor
brittle sinew
@eternal anchor does something like ClassViewer::Helpers::GetBlueprint(MyObject->GetClass()) not work?
eternal anchor
@brittle sinew idk, I didn't know something like this even exist (;
thanks
hmm
that's only partially helpful
it's decalred in cpp file ;/
but I can copy code, thanks (;
brittle sinew
Yeah I didn't try to build, just saw it
eternal anchor
ok
it actually does not work
because ClassGeneretedBy is never setup during blueprint creating
it's not setup for the actually class like UMyClass
idk if that is intended behaviour or just bug
ok
it's not that simple it seams
you have to cast your UObject
UBlueprintGeneratedClass* Class = Cast<UBlueprintGeneratedClass>(OutVal);
brittle sinew
Yeah I saw that, but is there any way to get the actual UBlueprint* from that?
I was wondering why you needed it, because AFAIK it's mostly just used for editor stuff
eternal anchor
after you cast to it ClassGeneretedBy is actually populated with UBlueprint*
i need it because I'm wirting custom blueprint editor
which will be embedded within other editor, I it just to edit properties
brittle sinew
Ah, okay. Good to hear it works, didn't really pay attention to that 😮
eternal anchor
oh damn
now i have to resolve linker errors
because some headers are private..

Hey guys - quick question... anyone else having issues with 4.14 STEAM integration? I have a 4.13 project that steam works fine - i can see available sessions when i use FINDSESSION() node, but in 4.14 i'm having no such luck.
FWIW - all the DefaultEngine.ini is the same for both versions, and yes SteamOnlineSubsystem is enabled in project. When we launch the STANDALONE GAME playmode, we can both see eachother come online in steam API and playing SpaceWar - but the session is not viewable in our created game. Again - this is workign no problem in 4.13 LAUNCHER but not 4.14 SOURCE
I've tried both AdvancedSessions plugin as well the engines default CreateSession and FindSession nodes
native axle
@worthy wasp I had issues with the AdvancedSessions plugin in 4.14 but the default nodes worked fine. Perhaps try a blank project without the plugin?
worthy wasp
@native axle were looking at some AV on the other end (mine works fine for the 4.13 so i'm going to rule mine out - even though i've disabled it temproarily)
I'll give a test project a go here shortly if this doesnt work! Thanks for a quick reply
wary willow
@native axle what issues did you have with Advanced Sessions plugin in 4.14? I was going to use it for my school project, but if it's bugged, I can just use the regular nodes.
native axle
@wary willow For the create and join session nodes, it has the success / fail out exec. I would get failure when using the plugin but not when using the default nodes. I can't remember if it was join or create session but one of them was bugged.
worthy wasp
No dice on the AV - and we removed the plugin all together.... i'm making a new project (4.14.3 SOURCE) and testing very basic connectivity with Steam
create session (for me) worked fine - it was the FIND SESSION that wasnt returning results
gaunt kestrel
^ create session also works for me
but find session wasnt returning results either
worthy wasp
this was both for Standard BP Nodes + also the AdvancedSessions plugin nodes
again - works fine in 4.13
native axle
Hmm I'll give a go on 4.14, been working in 4.13 too just to be safe.
worthy wasp
@gaunt kestrel are you successfull with the engine standard CreateSession() and FindSession() nodes?
gaunt kestrel
Yes
worthy wasp
hmmm - wonder if AdvancedSessions left behind a trail in my project....
i currently DONT have any c++ in it
but the engine standard nodes wont work either
gaunt kestrel
I tried getting the length
wasnt working
the console command "open IP" works for me
native axle
Were you testing with steam?
worthy wasp
steam API works fine - i can see each of us login to SpaceWars
gaunt kestrel
all ethernets plugged into switch
worthy wasp
so your NOT on steam - and still getting the same thing
gaunt kestrel
yeah
worthy wasp
definitely an OSS bug internal to engine maybe?
gaunt kestrel
maybe? maybe were just doing it wrong
worthy wasp
no - cuz this same practice works fine in 4.13
gaunt kestrel
try a for loop with break, then print each result
worthy wasp
i literally JUST tested it a few hours ago - i'm in a 4.14 BLANK project now and creating up the project to test again WITHOUT the AdvSessions plugin
worthy wasp
that would be awseome FPWong
gaunt kestrel
Nah I have a multiplayer test project
just not working
open IP is working though
thats why I haven't been too stressed about it
worthy wasp
ty sir got it
native axle
@gaunt kestrel what do you mean by open IP though?
gaunt kestrel
the console command used to open levels
but instead as long as your map has the ?listen option
it can be used to join
native axle
ahh
gaunt kestrel
Hmm
well its working in editor right now
but not in package
Also how do we used Get Controller Player ID?

@gaunt kestrel what do you mean by how do we use GetControllerPlayerID() ?
in multiplayer - controllers arent replicated - only yourself & the server knows of your controller
server knows of EVERYONES controller
so you can safely use GetPlayerController(0) and it will ALWAYS return yourself
gaunt kestrel
When my player grabs an object (VR, so they literally grab it) it spawns and has them possess a pawn.
worthy wasp
unless you are in p2p (LISTEN) server mode - which will return the SERVER controller if you are the host
worthy wasp
which you would have to use GetPlayerController(1) as the server to get your PLAYERS controller - not the server
its a bit confusing - but nothign hard to grasp
gaunt kestrel
@worthy wasp I think it should be >1
fossil spoke
Public Connections is basically your MaxPlayers
worthy wasp
thats what i thought too
but changing it made little difference in my original project
i'm almost done with this implementation now on a blank TPS template

@worthy wasp mine is working in editor?
I'll share pics once done making food
doesnt work in packaged game tho :c
native axle
Mine is working in packaged, not using the IP thing though
I cant see what nodes ur using with that btw just says latentonlinecall
worthy wasp
create session - you have 0
gaunt kestrel
Hmm well
worthy wasp
instead of ExecuteCommand() - why not use OpenLevel?

gaunt kestrel
.-.
worthy wasp
from what i've read - ExecuteCommand doesnt work in packaged game
gaunt kestrel
it does, just a little hackishy
I did the test project a while ago before going to the open IP commands
so don't know why that is
bold cedar
When connecting via IP, the clients all need to port forward 7777 (Or the default port)? Or just the host?
worthy wasp
jus tthe host - but thats LAN only
bold cedar
What about public hosting? Say a game jam, where I wanted players to join my session
worthy wasp
as far as I know port forwarding 7777 is for dedicated servers only
i'm sorry - might be some misleading information from my first reply
bold cedar
I can confirm that it is required for a player host, not only (if) dedicated servers
I'm mainly just wondering about players on the other end, if I am hosting it as a player.
worthy wasp
i'm right now testing this - i'll confirm it in a minute
and let you know
@bold cedar
bold cedar
@worthy wasp Thanks
worthy wasp
@native axle you alive?
@bold cedar - i'm UNSUCCESSFULL with 4.14.3 project - showing sessions
LENGTH = 0 EVERY TIME
yes port forwarding is turned on 7777-7778
everytime - length = 0
bold cedar
But if you were to now port forward on the client too, it would be successful?
worthy wasp
i'm going to safely say it doesnt matter
port 7777 is for dedicated servers
has nothing to do with OSS - especially steam
i know for a fact because i've developed a few games & launched to my brother for testing - and he has 0 port forwardign turned on
and can both host & join games successfully
bold cedar
What do you mean for dedicated servers?
bold cedar
I'm not so sure
I was unable to connect for testing with someone peer to peer, until we both port forwarded, and then it worked flawlessly
bold cedar
:p
worthy wasp
@bold cedar tested both ways - from me hosting & also him hosting..... 0 sessions returned
port forwarding is turned on both sides
7777 & 7778
bold cedar
You're using null subsystem?
worthy wasp
hey VB
bold cedar
Null will only work with LAN :p

Check this out
worthy wasp
i'm checking

wary willow
So, i fixed this by...
Shit, let me just get on my laptop
actually, think it's on my desktop
lalalala
So yeah
If this is intentional. no idea.
But, whatever
worthy wasp
do you think its a delay issue then?
wary willow
No idea
worthy wasp
because youre delaying right off the bat on begin play
but not on the RETRY function
wary willow
And mine is a little funny looking because I know I am only needing two players
So, one is either hosting or joining
Doesn't matter to me who is who
The delay is because it takes some time for Steam Session to come
Well, Steam to start up
You ever notice that delay for that window?
It's not instantaneous
But tbh, I am pretty sure it had nothing to do with the delay, but can't remember right now, it's 3am
bold cedar
What exactly is the problem?
worthy wasp
putting in a delay before the FindSession() node does nothing
bold cedar
@worthy wasp So in your case, with it not working with port forwarding, how would you connect peer to peer?
wary willow
Well
I am doing it this way for my own project, because it works
As far as why you can't find a session
Wait..
Is that inside an UMG?
worthy wasp
again @bold cedar - i cannot in 4.14.... but USIN GHTE SAME EXACT SETUP in 4.13 I can
bold cedar
Oh
wary willow
Have you tried moving this to like Game Instance or something?
Not sure what your exact requirements are
worthy wasp
in my actual project (not a test blank 4.14) yes its setup properly using GameMode, GameInstance & PlayerControllers
wary willow
But I ran into an issue with HUD class
worthy wasp
replicating GenericShooter example for functionality
wary willow
in 4.14.3
worthy wasp
i dont use HUD class
wary willow
That did not allow players to get control in packaged builds
but it worked just fine in editor
Your tests are all in packaged?
worthy wasp
Standalone playmode
wary willow
Why?
worthy wasp
which is supported + tested to work fine
wary willow
Have you tried packaged?
worthy wasp
why not? it works
wary willow
Because it doesn't always work...
bold cedar
^
worthy wasp
dont really want to waste the time packaging to test iterations
