#

no it doesnt

#

in 4.13 sure it does

wary willow Jan 19, 2017, 7:58 AM

#

Then wtf are you talking about

worthy wasp Jan 19, 2017, 7:58 AM

#

in 4.14 no it doesnt

wary willow Jan 19, 2017, 7:58 AM

#

So, you haven't once tried packaged?

worthy wasp Jan 19, 2017, 7:58 AM

#

dont even waste the time nope

#

specialyl for a 10gb+ project

bold cedar Jan 19, 2017, 7:58 AM

#

Might as well test it out...

wary willow Jan 19, 2017, 7:58 AM

#

I am telling you that there are differences, maybe 4.14 issue, between Editor and Packaging

worthy wasp Jan 19, 2017, 7:59 AM

#

i'll push heavily on the issue being with 4.14 - i'm moving this to UnrealAnswers tor tech support there

#

thought i'd ask here to see if people had the same problem

wary willow Jan 19, 2017, 7:59 AM

#

...

worthy wasp Jan 19, 2017, 7:59 AM

#

have a good night

Anyone here having run into issues replicating MotionController keypresses to client where VR isnt enabled? I have a 2 Pc setup - one running a spectator client(no vr) and a client running a vr pawn. When using events that are run using MotionController keypresses nothing gets send to the server.

native axle Jan 19, 2017, 11:21 AM

#

@worthy wasp Well, I'm back now :S Seems like it's still not fixed. It is not working only when connecting via ip correct?

native moth Jan 19, 2017, 11:40 AM

#

to add on my previous question... Im seeing some very wierd behavior here.
I have this simple setup in my PlayerController

📎 unknown.png

#

When I run this code with a normal pawn and no HMD, everything works.

#

But as as soon as I turn HMD on inside one my clients, all RPCs stop working

#

Anyone knows how to get around this?

thin stratus Jan 19, 2017, 11:51 AM

#

Input is still working?

native moth Jan 19, 2017, 11:55 AM

#

yes, "Client" is getting printed on my client

#

@thin stratus Im thinking this might be because I turn on the HMD after I have joined the session. Might be worth doing a transition map between the menu and the session that turns on the HMD

thin stratus Jan 19, 2017, 12:04 PM

#

Hm last time I connected to a Server as a VR client I made sure that my .exe has -vr

native moth Jan 19, 2017, 12:05 PM

#

Yeah. in this case the game has two modes, a spectator or VR - so when you open it up first time you're prompted using a standard window, if you select VR it allows you to connect to a session and then when the session is joined, it turns on HMD features

#

Tracking and everything works 100% as long as you are the server, as soon as you are the client with HMD on, the RPCs stop working

thin stratus Jan 19, 2017, 12:08 PM

#

But you are testing that in standalone or?

native moth Jan 19, 2017, 12:09 PM

#

right clicking on the uproject file and launching 2 instances on 2 different computers. One with HMD and one without

thin stratus Jan 19, 2017, 12:09 PM

#

Hm okay

#

Weird, RPCs only stop working if ownership is wrong, the actor isn't set to replicate or the net connection is dead

native moth Jan 19, 2017, 12:10 PM

#

so might be because ownership changes when the HMD turns on

thin stratus Jan 19, 2017, 12:10 PM

#

Na, you are on the playercontroller

#

That's yours, if that owner changes then you have other problems

#

You are sure the vr client correctly connects?

native moth Jan 19, 2017, 12:12 PM

#

yes. when I remove the turn on HMD, the print strings works as you would expect on my client instance and server instance

#

and the HMD is handled after the session has been succesfully joined

thin stratus Jan 19, 2017, 12:12 PM

#

I had problems using enable hmd

#

That always returned false for me

#

That's why i ended up opening the VR client with - VR directly

native moth Jan 19, 2017, 12:13 PM

#

Might have to try and create a seperate project where I open one with VR directly

#

and see if I get the same errors

thin stratus Jan 19, 2017, 12:14 PM

#

I don't know what that could be. Is printing the PlayerController name in tick firing correctly?

native moth Jan 19, 2017, 12:14 PM

#

will try, hang on a sec

thin stratus Jan 19, 2017, 12:14 PM

#

So like once for the server playercontroller and two times for the client?

#

You can open your projects with - VR directly. No need to create a new one

#

You only need your UnrealEditor.exe path and the uprojects path. Then you can create a bat file with commandarguments

native moth Jan 19, 2017, 12:16 PM

#

yeah I know, but my joining system interface is not enabled for VR yet :p

thin stratus Jan 19, 2017, 12:16 PM

#

Skip the joining

#

Just use the console

#

The VR preview allows that too

#

Open ipaddress

native moth Jan 19, 2017, 12:16 PM

#

arhh true.

#

Anyways, to answer your question, yes printing controller name in tick works as you would expect

#

2 times on server, once on client

thin stratus Jan 19, 2017, 12:18 PM

#

Okay other idea to test that

#

Open the editor and set the connection to be not made when you start the game

#

It's in the advanced settings

native moth Jan 19, 2017, 12:18 PM

#

Anyways, one way I could get around this is saying "Fuck syncing triggers on the server" - for the application I am doing I only need to sync the meshes transform I am moving with my controller. This is not a open multiplayer game but a closed conference project

thin stratus Jan 19, 2017, 12:19 PM

#

Then start the game in editor with 2 players

#

Let one host and one connect as a vr client

#

And then breakpoint the playercontroller

#

And see what really happens

native moth Jan 19, 2017, 12:19 PM

#

📎 unknown.png

#

this one youre refering to?

thin stratus Jan 19, 2017, 12:20 PM

#

Yeah, think it needs single processes active

#

Then you will see a new boolean

#

Which says something about connect to server instantly or so

native moth Jan 19, 2017, 12:20 PM

#

📎 unknown.png

#

this is the standard settings, I had actually turned off the use single process

thin stratus Jan 19, 2017, 12:21 PM

#

Set the player count to two

native moth Jan 19, 2017, 12:21 PM

#

arhh

thin stratus Jan 19, 2017, 12:21 PM

#

That should enable the bool to be set

native moth Jan 19, 2017, 12:21 PM

#

there I see it

#

hang on, will try

thin stratus Jan 19, 2017, 12:21 PM

#

Could be that this ends in weird things in the vive

#

As you have two windows on a single procrss and the vive doesn't like that

#

But debugging should still work

native moth Jan 19, 2017, 12:22 PM

#

Hmm, seems like they are still interconnected as the Print Strings shows on both instances, even with the bool off

thin stratus Jan 19, 2017, 12:22 PM

#

That's the single processes

#

Process

#

Not the net connection

native moth Jan 19, 2017, 12:23 PM

#

arhh. Anyways, when connecting it works as you would expect. 1 string on client, 2 strings on server

thin stratus Jan 19, 2017, 12:23 PM

#

Yes okay but since you are in the editor now

#

Open the playercontroller BP and set a breakpoint on the server rpc

#

You can also filter the playercontroller instances and see what lights up if you press the key

native moth Jan 19, 2017, 12:27 PM

#

yes, that works fine. Breakpoints activates fine on the server. Do note: Turn on HMD doesnt work when using PIE

thin stratus Jan 19, 2017, 12:29 PM

#

Turn on HMD aka enable hmd?

native moth Jan 19, 2017, 12:29 PM

#

Hmm. hold one... When I fire the RPC from my client, the breakpoint doesnt activate, but the server writes the string anyway. But when I fire the RPC from my server, breakpoint actiavtes

thin stratus Jan 19, 2017, 12:30 PM

#

Hm

#

What string

#

Client

#

Or Server?

#

Because remember the singleprocess

native moth Jan 19, 2017, 12:33 PM

#

okay so it seems like the client PC cant fire the RPC

thin stratus Jan 19, 2017, 12:34 PM

#

Makes not so much sense

#

What else are you doing when joining as VR

#

Something breaks if you do that

native moth Jan 19, 2017, 12:35 PM

#

GameInstance:

📎 unknown.png

#

GameMode

📎 unknown.png

#

PlayerController

📎 unknown.png

#

that is all

thin stratus Jan 19, 2017, 12:39 PM

#

Hm despite the GameInstance variable replicated which makes no sense and the pawn being saved to a variable after spawning while the controller has GetControlledPawn for that it seems all correct

native moth Jan 19, 2017, 12:39 PM

#

I will try and start up a new uncontaminated project and so some basic stuff and see if it works

#

Might have to rebuild some of this from scratch if this works

#

trying to go back to basics

bold cedar Jan 19, 2017, 12:43 PM

#

@thin stratus Hey Cedric, you know a good bit about multiplayer. Both the clients and the host must forward port 7777 (Or the default) to connect with the client-server model via IP? Or just the host?

thin stratus Jan 19, 2017, 12:46 PM

#

Just the host

#

The Host opens the port 7777 so other can try to connect to it

bold cedar Jan 19, 2017, 12:48 PM

#

Oh, I see. Cheers 😄

native moth Jan 19, 2017, 1:08 PM

#

@thin stratus okay so I did a complete basic test. When the app opens in VR and one in normal - everything works as you would expect

#

RPC etc. are firing and motioncontroller triggers work

thin stratus Jan 19, 2017, 1:09 PM

#

So it happens somewhere in your existing code?

#

Need to get ready for city, so won't be able to help the next few hours

native moth Jan 19, 2017, 1:09 PM

#

or its a problem with turning on the HMD during execution and not from the beginning

thin stratus Jan 19, 2017, 1:09 PM

#

Yeah that's what I thought

native moth Jan 19, 2017, 1:10 PM

#

so I will have to work around that by designing the interface to also work inside a couple of vr glasses

native moth Jan 19, 2017, 6:30 PM

#

@thin stratus just wanted to says thanks again. I got everything working when I start one instance as VR and one as normal! Had to do some stuff with the interface but it works alright 😃

thin stratus Jan 19, 2017, 6:31 PM

#

(: Sounds good

thin stratus Jan 19, 2017, 7:51 PM

#

Was anyone able to remove full games from the SearchResults of a FindSessionNode?

#

If you paste "MaxPlayers" to the Options list I get automated Kicking when the session is full (that's cool) but the session is still visible

#

I tried AGameSession::UpdateJoinability(FName InSessionName, bool bPublicSearchable, bool bAllowInvites, bool bJoinViaPresence, bool bJoinViaPresenceFriendsOnly);

#

And setting bPulbicSearchable to false once it's full ,but that didn't help

#

@chrome bay Did you encounter that yet

#

Or don't you have a ServerList?

chrome bay Jan 19, 2017, 7:54 PM

#

I do but it's basically the same as Alan Noons wild west shooter thingy, I hacked it together quickly a couple years ago... my latest venture with parties etc came from my starting to redo it properly haha

#

Can you not change the advertisement type of the server once it's registered then?

thin stratus Jan 19, 2017, 7:55 PM

#

So you filter it

#

I guess

chrome bay Jan 19, 2017, 7:55 PM

#

I do nothing atm haha

#

But am planning on filters etc, like BF4's ones

thin stratus Jan 19, 2017, 7:55 PM

#

Okay so just so you know, if you pass "MaxPlayers=16" it will kick player who join back to the main menu if it's full

#

By default

chrome bay Jan 19, 2017, 7:55 PM

#

Oo that's interesting

#

Does it give you a text warning, i.e. like "server full" or somethng?

thin stratus Jan 19, 2017, 7:56 PM

#

void AGameSession::InitOptions( const FString& Options )
{
    UWorld* const World = GetWorld();
    check(World);
    AGameModeBase* const GameMode = World ? World->GetAuthGameMode() : nullptr;

    MaxPlayers = UGameplayStatics::GetIntOption( Options, TEXT("MaxPlayers"), MaxPlayers );
[....]
}

#

FString AGameSession::ApproveLogin(const FString& Options)
{
    UWorld* const World = GetWorld();
    check(World);

    AGameModeBase* const GameMode = World->GetAuthGameMode();
    check(GameMode);

    int32 SpectatorOnly = 0;
    SpectatorOnly = UGameplayStatics::GetIntOption(Options, TEXT("SpectatorOnly"), SpectatorOnly);

    if (AtCapacity(SpectatorOnly == 1))
    {
        return TEXT( "Server full." );
    }

    int32 SplitscreenCount = 0;
    SplitscreenCount = UGameplayStatics::GetIntOption(Options, TEXT("SplitscreenCount"), SplitscreenCount);

    if (SplitscreenCount > MaxSplitscreensPerConnection)
    {
        UE_LOG(LogGameSession, Warning, TEXT("ApproveLogin: A maximum of %i splitscreen players are allowed"), MaxSplitscreensPerConnection);
        return TEXT("Maximum splitscreen players");
    }

    return TEXT("");
}

#

"AtCapacity" checks this:

chrome bay Jan 19, 2017, 7:57 PM

#

oh I see it there.. 'Server Full'

thin stratus Jan 19, 2017, 7:57 PM

#

bool AGameSession::AtCapacity(bool bSpectator)
{
    if ( GetNetMode() == NM_Standalone )
    {
        return false;
    }

    AGameModeBase* GameMode = GetWorld()->GetAuthGameMode();

    if ( bSpectator )
    {
        return ( (GameMode->GetNumSpectators() >= MaxSpectators)
        && ((GetNetMode() != NM_ListenServer) || (GameMode->GetNumPlayers() > 0)) );
    }
    else
    {
        const int32 MaxPlayersToUse = CVarMaxPlayersOverride.GetValueOnGameThread() > 0 ? CVarMaxPlayersOverride.GetValueOnGameThread() : MaxPlayers;

        return ( (MaxPlayersToUse>0) && (GameMode->GetNumPlayers() >= MaxPlayersToUse) );
    }
}

#

At the bottom in the else

#

It normally takes "MaxPlayers"

#

No idea what the CVar thing is

#

and how it works

chrome bay Jan 19, 2017, 7:57 PM

#

oh yeah that's wierd... wtf

thin stratus Jan 19, 2017, 7:57 PM

#

But it seems to be = 0 by default

#

Might by command vars that you pass when starting a Dedicated Server or so

chrome bay Jan 19, 2017, 7:58 PM

#

I think it's cus you can set 'MaxPlayers' in a config file somewhere

#

even so that does still look odd

thin stratus Jan 19, 2017, 7:58 PM

#

Yeah

#

We also have these in the GameSession

#

bool AGameSession::KickPlayer(APlayerController* KickedPlayer, const FText& KickReason)
{
    // Do not kick logged admins
    if (KickedPlayer != NULL && Cast<UNetConnection>(KickedPlayer->Player) != NULL)
    {
        if (KickedPlayer->GetPawn() != NULL)
        {
            KickedPlayer->GetPawn()->Destroy();
        }

        KickedPlayer->ClientWasKicked(KickReason);

        if (KickedPlayer != NULL)
        {
            KickedPlayer->Destroy();
        }

        return true;
    }
    return false;
}

bool AGameSession::BanPlayer(class APlayerController* BannedPlayer, const FText& BanReason)
{
    return KickPlayer(BannedPlayer, BanReason);
}

red ledge Jan 19, 2017, 7:59 PM

#

@thin stratus wait, game session had this kick player? I had to do it myself to be able to kick players in the UI lobby

thin stratus Jan 19, 2017, 7:59 PM

#

Well yeah, glory C++

red ledge Jan 19, 2017, 8:00 PM

#

no idea how to use AGameSession, thought that you had to modify the engine to use that

#

gonna look into it later

thin stratus Jan 19, 2017, 8:00 PM

#

No

#

You can just create a ChildClass of that

#

But you need to also have a Child of GameModeBase

#

as that one (why ever) is hardcoded to use GameSession

#

And the Variable that you can set in the GameMode BP window does nothing

#

gg

#

Even if you set this

#

https://puu.sh/ts32C/c5ee305b95.png

#

It stil ldoes this

#

{
    return AGameSession::StaticClass();
}```

#

Screams for a PR to actually use the GameSession variable that the GameModeBase has defined

#

:D

chrome bay Jan 19, 2017, 8:02 PM

#

that is true haha

thin stratus Jan 19, 2017, 8:02 PM

#

But I feel like Epic doesn't want to expose that to BPs

#

Too complex xD

#

But yeah if you override the function i just quoted

chrome bay Jan 19, 2017, 8:02 PM

#

I guess Game Session doesn't reallty have a lot you can do in BP's

thin stratus Jan 19, 2017, 8:03 PM

#

with the StaticClass of your own GameSession class

#

or with the variable and then set it in BPs

#

you can have your own gameSEssion

#

Just make sure to set the GameSession to "Blueprintable" in the UCLASS

#

otherwise it's C++ only

#

Well it doesn't but the funtions are really not that complex

#

You could easily expose all of them

#

making the GameSession base class Blueprintable

#

No idea why that's not a thing

#

I mean we also miss a "UpdateSession" node

#

I will try to update the current session

#

And stop advertising it

red ledge Jan 19, 2017, 8:09 PM

#

Thanks, I will check that tommorw when I wake up , might have to change my code to use the game Session

#

as for the not visiable thingy I just don't show it in UI but that's kinda hacky

#

but again the plyer can only see it when they search sessions

thin stratus Jan 19, 2017, 8:10 PM

#

They get kicked if it's full anyway

red ledge Jan 19, 2017, 8:10 PM

#

I really wish they can do something to at least make the session results update in real time

thin stratus Jan 19, 2017, 8:16 PM

#

That's nothing they can do

#

It's an async task

chrome bay Jan 19, 2017, 8:24 PM

#

until we have quantum computers and lightspeed internet connections we are slaves to async stuff 😄

polar bridge Jan 19, 2017, 8:26 PM

#

@thin stratus have you had any problems with game session with your project? i was having troubles overriding functions, but later found it was apparently a logging issue. the problem is i need the logging to help figure out how to code it lol 😄 specifically i was trying to run RegisterServer with no luck

#

i'm on UE 4.14

thin stratus Jan 19, 2017, 8:27 PM

#

RegisterServer, DedicatedServer, Steam, 4.14 Launcher Version?

polar bridge Jan 19, 2017, 8:27 PM

#

yes, yes, yes, no

#

built from source

thin stratus Jan 19, 2017, 8:27 PM

#

But untouched?

polar bridge Jan 19, 2017, 8:28 PM

#

correct

thin stratus Jan 19, 2017, 8:28 PM

#

Then you are "simply" missing a PR that fixes that

#

Steam + Dedicated Server is broken otherwise

polar bridge Jan 19, 2017, 8:28 PM

#

oh, good to know! i'll try to find that, thank you much!

thin stratus Jan 19, 2017, 8:30 PM

#

Does anyone remember in what file the SessionBP nodes are

#

welp nvm

polar bridge Jan 19, 2017, 8:33 PM

#

do you know if that PR is on the official github or is that the one that's out there made by some other guy on another repo?

thin stratus Jan 19, 2017, 8:35 PM

#

official github

polar bridge Jan 19, 2017, 8:36 PM

#

https://github.com/EpicGames/UnrealEngine/pull/2135 ?

thin stratus Jan 19, 2017, 8:36 PM

#

Yes

polar bridge Jan 19, 2017, 8:36 PM

#

awesome, thanks again

thin stratus Jan 19, 2017, 8:37 PM

#

So, for whatever reason, I can't get the NameSession from the Subsystem NULL

#

FNamedOnlineSession* NamedSession = OnlineSession->GetNamedSession(GameSessionName);

#

Hm cool

#

Seems like OnlineSubsystemNULL has no Sessions registered

#

coolio

#

-.-

chrome bay Jan 19, 2017, 8:41 PM

#

haha

#

ahh.... multiplayer

#

ShooterGame will only get us so far

#

and UT mods the engine

#

sigh

thin stratus Jan 19, 2017, 8:51 PM

#

whaaaaaaaaaaaaaaaaaaat

#

I have a BreakPoint on "GetNameSession"

#

And sometimes it calls and the Sessions Array is empty

#

and sometimes I have the Session in there

#

WHAT IS GOING ON

brittle sinew Jan 19, 2017, 8:53 PM

#

Are you calling it at a point where you know the session has been active for a little bit? Only think I could see there is a race condition 😮

thin stratus Jan 19, 2017, 8:53 PM

#

I created the Session on my first Instance

brittle sinew Jan 19, 2017, 8:53 PM

#

(barring pure magic)

thin stratus Jan 19, 2017, 8:54 PM

#

it gets added to the Array

#

then a new client connects and the SERVER tries to update the session

#

but the array is empty

#

¯_(ツ)_/¯

#

FLIP THE EDITOR

#

it's an editor thing

#

again

#

if I start it as standalone, it works

#

But even with the UpdateSessions thing I can't get the Session from Appearing in the list

chrome bay Jan 19, 2017, 9:07 PM

#

haha

#

good old PIE

thin stratus Jan 19, 2017, 9:08 PM

#

So

#

I would simply say

#

SubsystemNULL does not support hiding the Session

#

I just looked through the SessionSearch code

#

and it's searching for all open LanBeacons

#

Just a plain Broadcast

#

and then fills in the Results

#

it's not even checking if they advertise or not

#

void FOnlineSessionNull::OnValidQueryPacketReceived(uint8* PacketData, int32 PacketLength, uint64 ClientNonce)
{
    // Iterate through all registered sessions and respond for each one that can be joinable
    FScopeLock ScopeLock(&SessionLock);
    for (int32 SessionIndex = 0; SessionIndex < Sessions.Num(); SessionIndex++)
    {
        FNamedOnlineSession* Session = &Sessions[SessionIndex];

        if (Session)
        {
            bool bAdvertiseSession = ( ( Session->SessionSettings.bIsLANMatch || Session->SessionSettings.bAllowJoinInProgress ) && Session->NumOpenPublicConnections > 0 ) ||
                Session->SessionSettings.bAllowJoinViaPresence || 
                Session->SessionSettings.bAllowJoinViaPresenceFriendsOnly;

            if ( bAdvertiseSession )
            {
                FNboSerializeToBufferNull Packet(LAN_BEACON_MAX_PACKET_SIZE);
                // Create the basic header before appending additional information
                LANSessionManager.CreateHostResponsePacket(Packet, ClientNonce);

                // Add all the session details
                AppendSessionToPacket(Packet, Session);

                // Broadcast this response so the client can see us
                if (!Packet.HasOverflow())
                {
                    LANSessionManager.BroadcastPacket(Packet, Packet.GetByteCount());
                }
                else
                {
                    UE_LOG_ONLINE(Warning, TEXT("LAN broadcast packet overflow, cannot broadcast on LAN"));
                }
            }
        }
    }
}

#

Interesting to dive into the Packet data stuff

#

So basically, this happens if someone receives the broadcast

#

And this line defines if we responed:

                Session->SessionSettings.bAllowJoinViaPresence || 
                Session->SessionSettings.bAllowJoinViaPresenceFriendsOnly;```

#

Which, funny enough, doesn't even check if bSouldAdvertise is true

#

LOL

null subsystem is hax basically

#

USE IT EPIC

chrome bay Jan 19, 2017, 9:17 PM

lol

thin stratus Jan 19, 2017, 9:17 PM

#

So what do I need to do to stop it from sending packages back, let's see

#

Session->SessionSettings.bAllowJoinViaPresenceFriendsOnly needs to be false

#

Session->SessionSettings.bAllowJoinViaPresence needs to be false

#

( ( Session->SessionSettings.bIsLANMatch || Session->SessionSettings.bAllowJoinInProgress ) && Session->NumOpenPublicConnections > 0 )

#

NumOpenPublicConnections needs to be = 0, which I don't know how to do

#

bIsLANMatch is true anyway

#

Damn

#

Lemme check if the NumOpenPublicCOnnections is 0 anywa

#

Alright, NumOpenPublicConnections sorts itself

#

So lets try to set the other things to false

#

coolio, works

#

So I finally found out how to hide sessions that are full

#

For SubsystenNULL at least

Is there a better way of teasting VR Multiplayer?

#

It's hard because everytime we want to try something we have to package our game

modern fable Jan 20, 2017, 1:11 AM

#

why so? right click -> launch game

#

@gaunt kestrel

wary willow Jan 20, 2017, 1:12 AM

?

#

Nah, package

that's the best and only way to really do it

It's not that hard

It will save you more time in the end

well, it does work just fine like that

wary willow Jan 20, 2017, 1:13 AM

Launch game doesn't allow my friend on another pc/ another headset to connect

#

I got some general bugs in packaged.

I think most of it can be fixed by making sure the right check mark boxes are checked

#

There is this one where the client player can't apply damage to the server player.

All it's doing is a sphere trace for objects and applying the damage to the hit object

red ledge Jan 20, 2017, 7:19 AM

#

@thin stratus so how do you hide full sessions for NULL?

#

also, I wanted to ask, if I'm making a custom session, you said that I have to do it in the game mode, so does all game modes in my game have to have that override?

#

or just the main menu one

red ledge Jan 20, 2017, 8:31 AM

#

if I'm having a sort of item shop for a match, just something that you buy stuff from for the duration of that match

#

the items only give states, they don't exist in the world or have any use either than that

#

but I want if the player died and respawned to have their items still

#

and maybe other players can see those items online as well

#

should I put the item inventory on the pawn or the player state or the player controller?

#

or something like have them in the pawn but with a ref of only important info like a struct array on the player state for other players to see?

#

the items themselves are UObjects

rare cloud Jan 20, 2017, 9:32 AM

#

@red ledge, If inventory persist after death, use PlayerState

red ledge Jan 20, 2017, 9:32 AM

#

yeah it does, goonna use the probably but thought gameplay important stuff should be on pawn or player controller

rare cloud Jan 20, 2017, 9:33 AM

#

it really depend, and you can easily get playerstate from character

dense citrus Jan 20, 2017, 10:21 AM

#

hello who knows , how i get player name over head as a Widget , as text render ist works

subtle sonnet Jan 20, 2017, 10:56 AM

#

📎 unknown.png

#

Does that seem like a reasonable flow for master/instanced ( on demand ) server flow?

#

With a back-end handling players allowed to connect

#

Since the client would be the only one with valid information about itself when it's moved to a new server

#

Mass instances would be pre-match instances that players can roam around in while waiting for a match.

#

My goal for the project is to have a four tiered system ( Back-end API, Master Server, Large instances (max 500), and Small instances (max 20)) and then spin up large/small instances as needed using docker and dedicated servers.

thin stratus Jan 20, 2017, 11:57 AM

#

@red ledge Custom Session Class is like a Custom GameState, PlayerState, Character etc one. So yes, your GameMode defines the session class. The GameMode of your running game should have that. The MainMenu doesn't need to if you don't need any functionality there. I often don't even have a game mode for my main menu

#

And for the Inventory question: might be good to save it on the PlayerState. Mine is a component so I can stuck it onto everything i want

#

It's currently on the PlayerController

red ledge Jan 20, 2017, 12:55 PM

#

@thin stratus I mean, I do the hosting in the main menu (you basically click host game and write some stuff) and I have a diffrent game mode for the lobby and another diffrent one for the game, so should I put the GameSession class override in all of them?

thin stratus Jan 20, 2017, 12:55 PM

#

You put the GameSession override in the GameModes that have GameSessions active

#

Your MainMenu normally doesn't

#

I mean, if you have functions inside of the GameSession class that you need in your mainMenu

#

then yeah, then you need to override it there too

#

An easier way would be simply creating a new Base GameMode

#

overriding the variable there

#

and then just reparenting the other gamemodes

red ledge Jan 20, 2017, 4:12 PM

#

probably gonna do that, thanks

#

I think you need to modify the source to make your own online session settings tho, right?

torn gust Jan 20, 2017, 4:18 PM

#

Hey, i have read that binding functions to umg widgets is performancewise fast , but doing it with setting the value directly is faster. The thing is, i can´t get it to work and i can´t find any documentation on this for now. Casting to the UMG widget directly to change something with custom event does not work like it does with binding.

chrome bay Jan 20, 2017, 4:20 PM

#

Bindingss to functions / variables is slow. It's better to just modify the widget component in place, even if you do it from ticking.

torn gust Jan 20, 2017, 4:22 PM

#

Jeah. But how is this done in Multiplayer ?

#

📎 Health.JPG

chrome bay Jan 20, 2017, 4:28 PM

#

Widgets don't replicate if that's what you mean

#

Each client has their own local copy of a HUD which updates itself locally, not via the server

#

you'll quickly run into the bandwidth limit trying to update client huds from the server

torn gust Jan 20, 2017, 4:28 PM

#

So why does function binding work and direkt custom event node not ?

#

+does not

#

📎 Health2.JPG

#

This does replicate if its setup by binding. But not with custom event.

#

Huh maybe i lack the knowledge to explain this better. All i found was this statement : All that said, it really doesn't matter, all the binding options are much slower than setting the value directly. So if you need performance, avoid binding all together, set the values directly on the widget.

#

So i can´t figure out what to do if i want to just to that as Nick Darnell says.

#

Okay and maybe health isn´t the right thing to use here but i wanted to do the same thing what the binding does but manually. Page 33 http://cedric.bnslv.de/Downloads/UE4_Network_Compendium_by_Cedric_eXi_Neukirchen.pdf

thin stratus Jan 20, 2017, 4:58 PM

#

@red ledge No you can simply inherit from the existing ones

#

check ShooterGame for that

torn gust Jan 20, 2017, 5:03 PM

#

@thin stratus can you explain why we use binding function for health if this is performance whise not the direct way ? I really want to understand that part.

chrome bay Jan 20, 2017, 5:06 PM

#

@material the non-direct way is to set the actual value of the object

#

For example, if it's a progress bar, you do UProgressBar->SetPercent(HealthRatio);

#

It's faster to do that in the 'NativeTick' of a widget, than to use a binding

torn gust Jan 20, 2017, 5:07 PM

#

I am already doing that. But i cant understand how to set up that this is replicated.

chrome bay Jan 20, 2017, 5:08 PM

#

You just replicated the Health value, and the clients update their widget on tick

#

The server has no knowledge of client widgets, so it can't call server functions on them. Widgets have no ability to replicate

torn gust Jan 20, 2017, 5:08 PM

#

📎 Health3.JPG

chrome bay Jan 20, 2017, 5:09 PM

#

As I said, they don't replicate - so you can't do any networking functions with them

torn gust Jan 20, 2017, 5:10 PM

#

Hmm so this Set percent needs to be done outside the widget ?

chrome bay Jan 20, 2017, 5:10 PM

#

No it needs to be done in the widget - but you just replicate the health value

#

The widget updates itself on tick

#

By 'getting' the value from wherever it's replicated from

#

In your case, looks like the character

torn gust Jan 20, 2017, 5:14 PM

#

I don´t get it. This setup works with binding and tick. But not with Custom event inside the widget. So with binding health is replicated from my character. But with custom event not. Why and how to fix it then

#

Or isn´t it possible to prevent updates on tick for Widgets ?

chrome bay Jan 20, 2017, 5:15 PM

#

because the custom event isn't firing

#

You're trying to run a multicast event to set the percent - which will NEVER fire on the clients because widgets are not replicated

#

clients have their own local copy of widgets / UI etc - which is in no way linked to the server

torn gust Jan 20, 2017, 5:18 PM

#

Ok this now makes more sense to me now. That raises the question again what " all the binding options are much slower than setting the value directly" means. How this needs to be set up

chrome bay Jan 20, 2017, 5:19 PM

#

So a binding is kind of a separate 'object' in itself under the hood, which needs to be managed and taken care of - it therefore has overhead and has a cost of it's own.

#

They're convenient but slower than setting the value directly - BUT you probably won't notice a difference unless your game is very UI heavy

red ledge Jan 20, 2017, 5:22 PM

#

@thin stratus thanks, I will check the shooter example, AGAIN

torn gust Jan 20, 2017, 5:22 PM

#

Ahhhh you closed my Knowledge hole on this one perfectly now. Setting up values directly i therefore only possible if you set a variable inside a widget and let it read over event tick ? So you leave out this binding extra path ?

#

*is

#

Yeah it works !

#

Thanks man. This was quite hard to ask ( for me, iam bad at asking things)

chrome bay Jan 20, 2017, 5:24 PM

#

No worries :p

#

Check out @thin stratus's network compendium - it will help

torn gust Jan 20, 2017, 5:26 PM

#

I did. But i didn´t understand it out from there. This tiny little bit "So a binding is kind of a separate 'object' in itself under the hood, which needs to be managed and taken care of - it therefore has overhead and has a cost of it's own." was needed for me to understand this topic.

#

I often need this informations side by side alongside the tutorial or i can´t go further / can´t process information. Thats why it can be quite hard for me to to tutorials myself. Anyway. Cool to know this now and i can read deeper into it

chrome bay Jan 20, 2017, 5:38 PM

#

Can you set the tick rate in widgets? If you can change that instead of using the delay

#

tbh the delay there is probably just adding cost, setting pecent of a progress bar on tick wont really cost much 😃

torn gust Jan 20, 2017, 5:41 PM

#

Just to be clear, i am not afraid of performance costs haha 😃 I might sound like i am . But i wanted to understand the process. I never knew there is a tick rate setup for widgets.

wary willow Jan 20, 2017, 7:03 PM

#

#

@torn gust what are you doing?

#

What is that % value to? HP?

#

Yeah, so. HP/Damage is event based

You shouldn't run it on tick

wary willow Jan 20, 2017, 7:10 PM

#

Yeah no problem. Not that what you were doing was "wrong"

eternal swallow Jan 20, 2017, 7:10 PM

#

Btw, the delay after the tick just leads to your progress bar lagging behind the actualy value by 0.1 s. The function is still called every tick.

wary willow Jan 20, 2017, 7:10 PM

#

Obviously there are multiple ways to a solution in programming

#

Yeah, there's no reason for that delay at all, but I figured he took it off after Jamsh said something

torn gust Jan 20, 2017, 7:14 PM

#

Jeah was a stupid idea in general. It was more of a test thing. Delays per tick would make sense for line tracing or something that would be expensive to do extrem often. Event binding on a custom event is crazy powerfull, but i never understood how to set them up properly.

gaunt kestrel Jan 20, 2017, 7:15 PM

My client is unable to damage the server in a p2p network.

I'll give that a try when I get there

torn gust Jan 20, 2017, 7:49 PM

#

The tracing sphere is only visible on one window. Is this expected behavior ?

#

(dedicated)

#

Ah mistyped , non dedicated. Ok makes sense then. Haha

#

Wait, if this works from Server and from owning client which one is the right way ? From what i can guess , run the tracing on the Server favours all handling from the server which can mean that you saw you bullet hit another player but the server can decide you did not hit. On the other hand, shooting from the client side and hitting a target could lead to favour the least laggy player right ?

gaunt kestrel Jan 20, 2017, 8:03 PM

#

If it's set to multicast it's visible on both.

I want it to be able to damage no matter if you're host / client

#

Technically it's negative damage as it's a heal.

torn gust Jan 20, 2017, 8:05 PM

#

You mean multicast sphere tracing ?

gaunt kestrel Jan 20, 2017, 8:06 PM

#

Well if the event is set to multicast

I can see the debug sphere trace on both windows

torn gust Jan 20, 2017, 8:08 PM

#

Doesn´t that mean you trace two times if you have 2 players and one shoots ? It should trace for every player. Hm

It's okay! Thanks for your help. If what you did before allows client to damage host and host to damage client that will work just fine

torn gust Jan 20, 2017, 8:20 PM

#

Ah okay i overlooked that i did not drain the Healthbar on the other player and vice versa. So i assumed client side worked but it didn´t. Need to use second Screen 😛 Since my Vive steals one hdmi port iam stuck with one screen hehe. Guess i have to set up the viewports so that i can actually see whats happening. Now its all server side (tracing and damaging).

Check that your collision presets are correct and that you are correctly replicating the linetrace/projectiles

crimson pawn Jan 20, 2017, 11:41 PM

Figured out the problem, the projectiles were flying forward from the gun, and the aiming is done via animation blueprint, and looks like animation isn't performed in dedicated mode (which makes sense)

The "SpawnPawn" is NOT spawning a pawn

#

It's spawning a PlayerController

#

If you don't spawn an actual pawn and possess it it shouldn't work

wary willow Jan 21, 2017, 1:10 AM

#

All I know it worked when I played with it ¯_(ツ)_/¯

junior tree Jan 21, 2017, 1:10 AM

#

great! I'll be doing that

thin stratus Jan 21, 2017, 1:11 AM

#

ULocalPlayer* LocalPlayer = World ? World->GetGameInstance()->CreateLocalPlayer(ControllerId, Error, bSpawnPawn) : NULL;

#

This is what it calls

#

And "CreateLocalPlayer" does this

Unreal Engine

Implementing Local Multiplayer - Training Stream

▶ Play video

#

^---- there's a stream you can skim through

thin stratus Jan 21, 2017, 1:12 AM

#

ULocalPlayer* UGameInstance::CreateLocalPlayer(int32 ControllerId, FString& OutError, bool bSpawnActor)

#

There yo ucan see that boolean is suddenly "SpawnActor" instead of "SpawnPawn"

#

if (bSpawnActor && InsertIndex != INDEX_NONE && GetWorld() != NULL)
        {
            if (GetWorld()->GetNetMode() != NM_Client)
            {
                // server; spawn a new PlayerController immediately
                if (!NewPlayer->SpawnPlayActor("", OutError, GetWorld()))
                {
                    RemoveLocalPlayer(NewPlayer);
                    NewPlayer = NULL;
                }
            }
            else
            {
                // client; ask the server to let the new player join
                NewPlayer->SendSplitJoin();
            }
        }

#

WHich is used here

#

So if you set that to false you won't get a PlayerController

#

Yeah

#

That Stream shows the same

#

He is spawning the Pawns with pressing START on the Controller

#

The Node is not spawning a Pawn althoug the boolean says that

#

No idea why you are able to access the "ControllerPawn" in your image @wary willow

wary willow Jan 21, 2017, 1:17 AM

#

aliens ¯_(ツ)_/¯

#

That project was in 4.10

thin stratus Jan 21, 2017, 1:17 AM

#

Maybe it actually autoposseses the placed pawns that are in the level?

wary willow Jan 21, 2017, 1:17 AM

#

So who knows what I did there

junior tree Jan 21, 2017, 1:18 AM

#

so the create player function tells the game mode to check for player starts and spawn a player there

#

what if I want player starts to be single-use?

wary willow Jan 21, 2017, 1:18 AM

#

?

#

Like you have multiple spawn points?

#

Just add them all in an array at the start

junior tree Jan 21, 2017, 1:19 AM

#

4 spawn points, only use one

thin stratus Jan 21, 2017, 1:19 AM

#

Na the CreatePlayer function creates a new PlayerController

wary willow Jan 21, 2017, 1:19 AM

#

and then remove them accordingly

junior tree Jan 21, 2017, 1:19 AM

#

only use each once

#

allright

wary willow Jan 21, 2017, 1:19 AM

#

Right

thin stratus Jan 21, 2017, 1:19 AM

#

You can then use that PlayerController to possess a pawn

junior tree Jan 21, 2017, 1:19 AM

#

my createplayer creates a pawn with a player controller at a random player start

#

empirically

#

that's what it's doing right meow

wary willow Jan 21, 2017, 1:20 AM

#

But it works?

junior tree Jan 21, 2017, 1:20 AM

#

purr purr

#

it does that, I'd like to avoid using a player start twice is all

wary willow Jan 21, 2017, 1:20 AM

#

Right

junior tree Jan 21, 2017, 1:20 AM

#

maybe I can just re-position the pawns after they are spawned

thin stratus Jan 21, 2017, 1:20 AM

#

That node is so random then

wary willow Jan 21, 2017, 1:20 AM

#

lol

#

But it works

#

.shrug

thin stratus Jan 21, 2017, 1:20 AM

#

If you uncheck that boolean you don't get a PlayerController

#

xD

#

You get a ULocalPlayer, but that's not helpful in BPs

wary willow Jan 21, 2017, 1:21 AM

#

Obviously, if you wanted more control, you'd need to go into cpp

#

and build a function yourself

junior tree Jan 21, 2017, 1:21 AM

#

oooh I can uncheck that boolean

wary willow Jan 21, 2017, 1:21 AM

#

Or someone can do a PR for it

#

and maybe get it into 4.50

thin stratus Jan 21, 2017, 1:21 AM

#

Might be that the Node is hooked up with PlayerStarts

wary willow Jan 21, 2017, 1:22 AM

#

From PlayerState?

thin stratus Jan 21, 2017, 1:22 AM

#

That could be although I can't find anything calling something for a PlayerStart

wary willow Jan 21, 2017, 1:22 AM

#

PlayerState has that override function right?

gaunt kestrel Jan 21, 2017, 1:22 AM

#

Sphere Trace still not showing up for client .-.

thin stratus Jan 21, 2017, 1:22 AM

#

@wary willow Why suddenly PlayerState?

#

@gaunt kestrel Did you try to start it like I said?

gaunt kestrel Jan 21, 2017, 1:23 AM

#

I'm not using a VR Pawn, i'm using a third person pawn that inherits everything from my VR Pawn

wary willow Jan 21, 2017, 1:23 AM

#

I was wondering just thinking out loud

thin stratus Jan 21, 2017, 1:24 AM

#

@gaunt kestrel So you are not even using "VR Preview" or "Enable HMD" somewhere?

wary willow Jan 21, 2017, 1:24 AM

#

@junior tree https://gyazo.com/8254ec9a17d13f0b3149c2f5b6f93521 in my pawn

Just in case you were wondering

junior tree Jan 21, 2017, 1:25 AM

#

I think I'm gonna die

wary willow Jan 21, 2017, 1:25 AM

#

And I have that player setup in GameMode

gaunt kestrel Jan 21, 2017, 1:25 AM

#

just Simulate, can't really test VR Multiplayer without going through the whole packing process

#

thats why we have the FPS pawn that inherits

thin stratus Jan 21, 2017, 1:25 AM

#

Of course you can test that

gaunt kestrel Jan 21, 2017, 1:25 AM

#

0.o?

wary willow Jan 21, 2017, 1:26 AM

#

You can test MP VR via Steam in editor?

thin stratus Jan 21, 2017, 1:26 AM

#

Just start the game as StandAlone via command line with -vr and then use the console to start listen server and one to open the localhost address

#

You don't need steam for vr

wary willow Jan 21, 2017, 1:26 AM

#

So you mean LAN?

gaunt kestrel Jan 21, 2017, 1:26 AM

#

I'm not using steam when packaging

wary willow Jan 21, 2017, 1:27 AM

#

What are you using?

#

Ah direct ip?

gaunt kestrel Jan 21, 2017, 1:27 AM

#

A bunch of checks to see if they have a HMD or not, and @wary willow open level?listen on host, open IP on client

thin stratus Jan 21, 2017, 1:28 AM

#

In the Editor?

gaunt kestrel Jan 21, 2017, 1:28 AM

#

In editor, that was simulate loads in as a different pawn

#

Here I'll show you after I try Stand Alone

thin stratus Jan 21, 2017, 1:29 AM

#

Try this

#

nah

#

txt file

#

and replace .txt with .bat

gaunt kestrel Jan 21, 2017, 1:30 AM

#

oh this is .bat

#

ok

wary willow Jan 21, 2017, 1:32 AM

#

@twin juniper this is the correct channel to ask your question

#

Especially with Super MP ~~Nerd~~ Genius Exi here

gaunt kestrel Jan 21, 2017, 1:33 AM

#

apparently im unaware how to use this .bat file

#

and yeah Exi is a god

wary willow Jan 21, 2017, 1:33 AM

#

I've never seen it, so I can't help

#

Beg Exi

#

But

#

It seems pretty self explanatory

#

SET ProjectPath="FULL DIRECTORY PATH" to project

#

SET UProjectFileName= try Full Path to uproject or Just the uproject name

#

EnginePath=Full Directory Path to Engine Install

#

hmmm

#

same with the rest I guess

#

Actually no

#

You won't need to input anything after those 3

#

It's done in the echo for you

#

Anyway, those are just guesses, never seen this or tried it, just using common sense.

gaunt kestrel Jan 21, 2017, 1:36 AM

#

whoa cool

#

ok

wary willow Jan 21, 2017, 1:36 AM

#

did it work?

gaunt kestrel Jan 21, 2017, 1:37 AM

#

trying it

#

one sec

thin stratus Jan 21, 2017, 1:37 AM

#

Remember that you need a console key

gaunt kestrel Jan 21, 2017, 1:37 AM

#

it was "Oh cool" to how it works

thin stratus Jan 21, 2017, 1:38 AM

#

So you can do "open MapName?listen"

#

and "open 127.0.0.1"

gaunt kestrel Jan 21, 2017, 1:38 AM

#

wait am I launching this in stand alone?

#

it only opens one window

thin stratus Jan 21, 2017, 1:39 AM

#

One bat execution

#

is one instance

#

you start it twice

#

First instance will be open MapName etc

#

Second instance wil lbe open ip

#

Anyway, off for today

gaunt kestrel Jan 21, 2017, 1:44 AM

Can't find my engine path

hey exi so how do i remove a element in a TArray tha tis replicated in c++ but im looping through it in bps (I made an array to hold all my items and they are added by an overlap event). I then want to remove the item from the array when the player drags and drops the item off of the inventory interface (in umg)

#

what i need to know basically

#

is how do i access "Switch Has Authority" in bps

#

@thin stratus

@brittle sinew

The man is sleeping or having some fun

#

He gone

native axle Jan 21, 2017, 2:24 AM

@twin juniper I think its something like

Pawn->Role < ROLE_AUTHORITY

#

How do I format code in this?

#

Pawn->Role < ROLE_AUTHORITY

twin juniper Jan 21, 2017, 2:26 AM

#

lol

Role_authority

#

is an enum

#

lol

#

like theres an enum of all the different ones

#

i dont remeber them off the top of my head

#

I really wish discord had a spellchecker lol

native axle Jan 21, 2017, 2:28 AM

#

ohh u wanted it in BP?

twin juniper Jan 21, 2017, 2:28 AM

#

its w/e

#

for now

#

lol

native axle Jan 21, 2017, 2:28 AM

#

you can only call switch has authority from a pawn class

#

otherwise you have to store your player pawn and do a branch for "Has Authority"

#

or you can probably just do get player pawn 0 . has authority

subtle sonnet Jan 21, 2017, 4:21 AM

#

if it's umg that's pretty safe since a server will never have it, but if it's just a standard blueprint taking player 0 should be replaced with get owner

#

otherwise the server will simply take the first user off the user stack

gaunt kestrel Jan 21, 2017, 4:29 AM

#

how do we open a map and have all currently connected clients join

subtle sonnet Jan 21, 2017, 4:37 AM

#

https://docs.unrealengine.com/latest/INT/API/Runtime/Engine/Engine/UWorld/ServerTravel/index.html

Jumps the server to new level.

#

There's a bunch of those, but that seems like you best bet for your case ( There's ClientTravel, SeamlessTravel, and a few others if I'm not mistaken )

gaunt kestrel Jan 21, 2017, 5:07 AM

#

I'm in BP, run these as console cmds?

night jay Jan 21, 2017, 7:00 AM

#

Works

#

Buggy part about that thing is with Steam it kicks out half the players for some reason

#

So you have to look into seamless server travel

#

But in turn that won't work if you want to change gamemodes

civic light Jan 21, 2017, 7:49 AM

#

wait, what? I have seamless travel in my game and i can switch game modes

wary willow Jan 21, 2017, 8:34 AM

#

Well

#

Not sure how it would work in MP, but you could always Keep the same GameMode(actor) and just switch components in it

night jay Jan 21, 2017, 11:10 AM

#

@civic light can you show your code? I have a main menu gamemode and I want to switch to my gameplay gamemode

civic light Jan 21, 2017, 11:22 AM

#

are you using sessions?

thin stratus Jan 21, 2017, 11:43 AM

#

@twin juniper SwitchHasAuthority is just a single node. I don't get the question. In BPs you simply rightclick and search for it

#

@gaunt kestrel To open a map and move Players with you, as a server, you use ServerTravel

#

BP doesn't have a node for this so you need to use it as a console command

#

@night jay @civic light MainMenu to GamePlay is something else than GamePlay to GamePlay. ServerTravel is used for the later. I never actively used Seamless Travel but i was told a while ago that this will keep the GameMode class

civic light Jan 21, 2017, 12:00 PM

#

Its actually really easy to change the gamemode when using seamless travel. For example when a match is over, i call the following before ServerTravel. gamemode_class is just a TSubclassOf that i get from a function that randomly picks one of my gamemodes.

    FURL &test_url = Context->LastURL;
    if (gamemode_class.GetDefaultObject())
    {
        auto gamemodeobject = gamemode_class.GetDefaultObject();
        test_url.RemoveOption(TEXT("Game"));
        FString gamemodestring = "Game=" + gamemodeobject->MapPrefix;
        test_url.AddOption(*gamemodestring);
    }

night jay Jan 21, 2017, 12:16 PM

#

Thanks

thin stratus Jan 21, 2017, 12:49 PM

#

@civic light But this is ServerTravel

#

SeamlessTravel != ServerTravel

#

Changing the GameMode with ?game=GameModeShortName is something known so far

#

4.14 even features a functionality in "Maps and Nodes" to set Shortcut names directly in the Editor

#

Which was previously only possible with setting them in the ini file directly

civic light Jan 21, 2017, 12:50 PM

#

oh, nice

thin stratus Jan 21, 2017, 12:51 PM

#

But if you use SeamlessTravel, I'm still kinda sure (based on what I was told) that the GameMode class stays

#

Because the idea of SeamlessTravel is to keep Actors alive and, for example, move the previous saved data of your PlayerStates to the new map

#

Imagine something like Borderlands where you where traveling between zones

#

(always all together cause UE3 worked the same way)

#

That was probably a seamlesstravel

#

As you kept all the information ,the game mode, the PlayerState etc for the new level

#

But moving from Lobby to GamePlay where Lobby is probably a different gamemode, shouldn't work with SeamlessTravel

#

As that would mean the LobbyGameMode stays and the GameplayMap uses the wrong GameMode

#

that is what I learned. I never actually tested it as my first experience with SeamlessTravel was crashing in 4.6

civic light Jan 21, 2017, 12:53 PM

#

yeah, its different when it comes to using lobbies

#

personally im not using them for my game

thin stratus Jan 21, 2017, 12:53 PM

#

Well I have a lobby on the Marketplace

#

And I ServerTravel from Lobby to GamePlay level

#

I would love to keep selected stuff in the PlayerState and use "OnCopyProperties" and "OnOverrideWith" (can't remember which one is for the travel) to keep the data

#

But these functions need SeamlessTravel

#

so /shrug

#

I would like a semi-seamless Travel

#

Where you don't keep the classes, but you still have the ability to use the old PlayerState object to give the new one data

#

even if they are different classes

civic light Jan 21, 2017, 12:57 PM

#

what sort of properties are you looking to keep?

thin stratus Jan 21, 2017, 12:58 PM

#

Currently, the Players can select a Character and a Team in my Lobby

#

Since the Marketplace Project can't have Steam by default, I save the data in the GameInstance of each Player

#

And ask them in the GameplayMap for their choices

#

While this works, it's not really ideal

#

I could use Steams unique ID and save the selection together with the ID to the match them back up after they traveled to the Gameplay Map

#

But ideal would be, being able to Travel, getting all the new Class (gameMode and the classes that come with it) and having the PlayerState call "CopyProperties", giving me the instance of the old PlayerState (ALobbyPlayerState) so I can get variables from it to fill my "AGamePlayPlayerState"

#

But it seems like the whole CopyProperties thing is bound to SeamlessTravel and to the idea of keeping the GameMode and so also keeping the PlayerStateclass

hallow shore Jan 21, 2017, 1:28 PM

#

i save data to game instance and than restore it on server

#

@thin stratus is there are some tutorial you know how can i "repack" advanced session plugin (any plugin) with few more functions added?

thin stratus Jan 21, 2017, 1:33 PM

#

If they give you the source, you simply add the plugin to your plugin directory of your project and regenerate project files

#

then you can extend the stuff in their .h/.cpp files and hit build again

#

then you have the updated plugin

#

Nothing different than having a normal C++ project that you extend

hallow shore Jan 21, 2017, 1:35 PM

#

it has directory with source, which includes classes, private and build.cs
im not sure is that all source, probably all?

thin stratus Jan 21, 2017, 1:40 PM

#

Yes, this is Source

#

Mostly made out of a Build.cs, header and cpp files

#

:P

hallow shore Jan 21, 2017, 1:40 PM

#

😛

#

there are no bp function for is uniqueid valid, which give me nasty warnings all over the place 😐

thin stratus Jan 21, 2017, 1:41 PM

#

What keeps you from just adding that to your own project

#

instead of the plugin

hallow shore Jan 21, 2017, 1:42 PM

#

its not for myself.

night jay Jan 21, 2017, 3:38 PM

#

I have another question regarding seamless travel then

#

Can I change my default controller class

#

And does begin play happen in the gamemode after seamless travel?

gaunt kestrel Jan 21, 2017, 4:30 PM

#

ServerTravel "Levelname"?listen

or

ServerTravel "Levelname"

gaunt kestrel Jan 21, 2017, 5:09 PM

#

Also I'm having this weird bug where my client can't recieve inputs at all

#

didnt change anything, just opened the project this morning

thin stratus Jan 21, 2017, 5:46 PM

#

Without the listen

#

Listen is only for the initial call of creating the listen server

#

@night jay Seamless Travel keeps the GameMode and so also all the classes you setup in it

#

So no, you can't change the PlayerController class if you use Seamless Travel

#

It's only meant for scenarios where you want to keep everything but just switch the map

#

e.g. Borderlands zone change

night jay Jan 21, 2017, 5:48 PM

#

Issue is with Steam it's kinda necessary because normal server travel kicks out half the players

thin stratus Jan 21, 2017, 5:49 PM

#

That's weird

#

Would do the other clients get i nterms of log errors?

#

I mean, either you loose all clients or none

gaunt kestrel Jan 21, 2017, 5:51 PM

#

Well that works now. Thanks!

Problem is client can turn and look, but cant move or do other actions

night jay Jan 21, 2017, 5:53 PM

#

connection failed or whatever I can't remember exactly

#

But It's been bugging us since the beginning

thin stratus Jan 21, 2017, 5:57 PM

#

Well seems like Steam ServerTravel only works if you set Seamless Travel to true

#

Which will cause this:

#

Seamless Travel Flow

Here is the general flow when executing seamless travel:

1. Mark actors that will persist to the transition level (more below)
2. Travel to the transition level
3. Mark actors that will persist to the final level (more below)
4. Travel to the final level


Persisting Actors across Seamless Travel

When using seamless travel, it's possible to carry over (persist) actors from the current level to the new one. This is useful for certain actors, like inventory items, players, etc.

By default, these actors will persist automatically:

- The GameMode actor (server only)
-- Any actors further added via AGameModeBase::GetSeamlessTravelActorList
- All Controllers that have a valid PlayerState (server only)
- All PlayerControllers (server only)
- All local PlayerControllers (server and client)
-- Any actors further added via APlayerController::GetSeamlessTravelActorList called on local PlayerControllers

#

Hm

gaunt kestrel Jan 21, 2017, 6:04 PM

#

Hmm it seems that no matter the pawn I load in for client it doesnt want me to use wasd to move it. (spectator)

night jay Jan 21, 2017, 6:04 PM

#

Then steam is practically unousable if you want a lobby..?

#

Where you can actually connect to

thin stratus Jan 21, 2017, 6:09 PM

#

So, I just asked Moss and it seems like this:

The GameMode should NOT override the Gameplay level one if it'S different

#

Seamless Travel only keeps it completely if you have the same gamemodes setup

#

Of course you can't use the features of Seamless travel if the classes aren't the same :x

night jay Jan 21, 2017, 6:15 PM

#

what do you mean same gamemodes setup

#

I have a gamemode called MainMenu which is in my level's gamemode override

#

Then I server travel with a travel URL which includes a custom gamemode in the URL

#

Which does work if I have seamless off

thin stratus Jan 21, 2017, 6:17 PM

#

First thing is: Your MainMenu is not really important here

#

MainMenu -> StartServer is a "hard travel", which means non-seamless
MainMenu -> JoinServer is also a "hard travel"

#

Only if everyone is already on the Server you call ServerTravel

night jay Jan 21, 2017, 6:18 PM

#

I do that

thin stratus Jan 21, 2017, 6:18 PM

#

So the Lobby, which you probably opened as the first map, has the Seamless Travel on

#

Lobby has a LobbyGameMode

#

and as long as the GamePlay map doesn't have the LobbyGameMode too, it should seamless travel without keeping the GameMode

#

If not then we have a bigger problem :D

night jay Jan 21, 2017, 6:19 PM

#

Well I exactly have that already

#

And it doesn't

#

Although main menu gamemode and lobby gamemode are the same thing

#

My lobby is in my main menu

#

But that shouldn't matter

#

Server travel I try to load Deathmatch or whatever

#

Doesn't work

thin stratus Jan 21, 2017, 6:23 PM

#

So

#

Without clients in there

#

What exactly happens if you call Seamless Travel ServerTravel from Lobby to Gameplay

night jay Jan 21, 2017, 6:35 PM

#

It still keeps the mainmenu gamemode while I called it to use deathmatch

thin stratus Jan 21, 2017, 6:36 PM

#

@thin stratus would it be possible if you were to make a small example on how to set it up? I might be doing something wrong here..

thin stratus Jan 21, 2017, 8:01 PM

Currently no, sorry. Knee deep in work :(

Thanks anyway

#

Hello, all.

#

When I use the Create Session node and specify IsLAN = False, where is that session hosted?

thin stratus Jan 21, 2017, 8:41 PM

#

Without a Subsystem, nowhere

#

I mean, it's hosted on your PC

wary willow Jan 21, 2017, 8:42 PM

#

Oh

thin stratus Jan 21, 2017, 8:42 PM

#

But the Session can't be found online without a MasterServer

wary willow Jan 21, 2017, 8:42 PM

#

One question to make sure @thin stratus

#

If I have OSS Steam on, and have that also in the config

#

If I toggle LAN, I should be able to enjoy LAN out of the box, without additional setup?

ocean dust Jan 21, 2017, 8:42 PM

#

Ah, that's what I thought. How does one go about setting up a MasterServer?

wary willow Jan 21, 2017, 8:43 PM

#

Because I saw somewhere that I have to do SubSystem=null for LAN

#

But is that just for if the game is only LAN?

thin stratus Jan 21, 2017, 8:43 PM

#

LAN should work with Steam Subsystem

wary willow Jan 21, 2017, 8:43 PM

#

Right, just making sure.

thin stratus Jan 21, 2017, 8:43 PM

#

Well, I never tried it so I can't say for sure either

wary willow Jan 21, 2017, 8:43 PM

#

Hehe

#

I know it works in editor

#

But I've never actually tested it in Packaged

thin stratus Jan 21, 2017, 8:44 PM

#

@ocean dust Your own MasterServer? That's quite some work. There is a Plugin on the Forums that features a basic one.
But you might be better off using Steam (though remember they take 30% of your income from the game)

wary willow Jan 21, 2017, 8:44 PM

#

They take 30%

#

But, you get 10000000000000% more exposure

#

than you probably would alone

ocean dust Jan 21, 2017, 8:45 PM

#

Our plan is to launch on Steam anyway. But yeah... -30% + -5% + -10% ...

thin stratus Jan 21, 2017, 8:45 PM

#

True and a lot of additional stuff (like accounts etc)

wary willow Jan 21, 2017, 8:45 PM

#

Unless you had some crazy marketing and hype

thin stratus Jan 21, 2017, 8:45 PM

#

@ocean dust Well, without Steam, you would miss a lot of buyers

ocean dust Jan 21, 2017, 8:45 PM

#

Agreed

thin stratus Jan 21, 2017, 8:45 PM

#

And you would need to host your own MasterServer

ocean dust Jan 21, 2017, 8:45 PM

#

which is our plan

wary willow Jan 21, 2017, 8:45 PM

#

@ocean dust what's that 10%?

thin stratus Jan 21, 2017, 8:45 PM

#

And your own Database

#

etc for accounts

#

and Your own Cloud etc etc etc

ocean dust Jan 21, 2017, 8:45 PM

#

The way we see it:

#

-30% to Steam
-5% to Epic
-10% to taxes (probably way more)

wary willow Jan 21, 2017, 8:46 PM

#

TBH, I would say, if devs wanted to start off a little slow, but earn max profits, use Itch.io

#

then, go to Steam/Humble/whatever other new crap is out there

ocean dust Jan 21, 2017, 8:46 PM

#

Making games is HARD

thin stratus Jan 21, 2017, 8:46 PM

#

Taxes only 10%?

#

:D

wary willow Jan 21, 2017, 8:46 PM

#

I wonder what my taxes will be like.

thin stratus Jan 21, 2017, 8:47 PM

#

I mean, I don#t know about your Country etc, but I would be surprised if taxes really are that low

ocean dust Jan 21, 2017, 8:47 PM

#

It's just soul-crushing to know we'll see only 35% or less of our hard work

#

yeah

thin stratus Jan 21, 2017, 8:47 PM

#

Yeah you might only go home with ~35% of the actualy price

ocean dust Jan 21, 2017, 8:47 PM

#

It's probably closer to 25% for taxes

wary willow Jan 21, 2017, 8:47 PM

#

But tbh, If you are getting roughly 30% as profits, that's still pretty good

#

And that's what you should be accounting for when doing budgets

ocean dust Jan 21, 2017, 8:48 PM

#

Sadly, yes

#

Anyway

thin stratus Jan 21, 2017, 8:48 PM

#

I mean

#

Germany the taxes would be 35%+

#

So no idea where you live

ocean dust Jan 21, 2017, 8:48 PM

#

Is there a guide for getting Steam integration set up? I think I saw one a while ago and shifted gears away from MP

thin stratus Jan 21, 2017, 8:48 PM

#

but 25% is a bit dreaming

ocean dust Jan 21, 2017, 8:49 PM

#

Yeah...we're trying to be realistic

#

but still fight to get something out of all of this work

thin stratus Jan 21, 2017, 8:49 PM

#

Make it good

#

And it sells good :P

#

You can see how Steam Games sell iirc

#

How many copies

ocean dust Jan 21, 2017, 8:50 PM

#

yeah

#

but that's pretty optimistic

thin stratus Jan 21, 2017, 8:50 PM

#

Well doing all of that work while thinking yo uwon't earn anything

#

is kinda weird

ocean dust Jan 21, 2017, 8:51 PM

#

even if we net 2mil: 0.3 * 2,000,000 = 600,000

ocean dust Jan 21, 2017, 8:51 PM

#

That's the power of passion for making fun games and experiences

#

Meh

#

ANYWAY

#

Steam integration? I need that for a MasterServer to host my Sessions?

thin stratus Jan 21, 2017, 8:51 PM

#

That's why I don't create my own games xD

#

Yeah

#

They register there and your players can get a list of these back from the server

#

Of course Steam features a lot more

wary willow Jan 21, 2017, 8:53 PM

#

@thin stratus you don't create your own games?

#

what, I thought you had a VR project?

#

Like some exploration type game

thin stratus Jan 21, 2017, 8:54 PM

#

In my eyes, for me, a VR Project wouldn't cut it

ocean dust Jan 21, 2017, 8:54 PM

#

@thin stratus I'm making my own games

thin stratus Jan 21, 2017, 8:54 PM

#

More work than a normal Game
Less buyers cause of less people having a Vive

#

I would rather work on a non-vr Game

#

But as a single dev without any skill in art, I can't do that anyway

#

Maybe at some point in the future getting into one project with Celeste, but that's just a thought

wary willow Jan 21, 2017, 8:55 PM

@thin stratus You gave up on 3d modeling?

thin stratus Jan 21, 2017, 8:55 PM

It takes too much time atm

wary willow Jan 21, 2017, 8:55 PM

#

Wait, why aren't you two doing something now together?

thin stratus Jan 21, 2017, 8:55 PM

#

Freelancing for money needs time

Because both of us work on clients + she works on her Gamejam game with that leaf

No time to start another project

wary willow Jan 21, 2017, 8:56 PM

My relationship and my job are two different things

#

If I end up creating a game, with or without her, i want to sell the game, not my relationship :P

wary willow Jan 21, 2017, 8:57 PM

Right, but there's always a chance of wedding bells

#

And then you're definitely merging some stuff together, other than yourselves

thin stratus Jan 21, 2017, 8:57 PM

Oh sweet! I need an up-to-date guide on Steam integration

#

@stiff rapids Shouldn't the Weapon be in charge of determining what happens when it "hits" something?

#

@stiff rapids The Weapon should say "hey, Pawn, take some damage"

Instead of the Pawn determining "I was hit, therefor I need to take damage"

stiff rapids Jan 21, 2017, 10:32 PM

#

@ocean dust, yes, you are correct there, this is the end goal, but my problem is that the pawn is not reacting to the client correctly. even if the pawn right now decides what happens, the execution goes to remote instead of server, when the weapon calls the interface.

ocean dust Jan 21, 2017, 10:33 PM

#

@stiff rapids OK, so, you are doing a raycast check on the Client when you press the button

stiff rapids Jan 21, 2017, 10:33 PM

#

@thin stratus Yes, i know that. 😃 just trying my own thing.

ocean dust Jan 21, 2017, 10:34 PM

#

@stiff rapids You should send an RPC to Server to ask it to "use" your weapon

#

which will then to the raycast and messaging on the Server

stiff rapids Jan 21, 2017, 10:34 PM

#

@ocean dust Yes right now i am, i was doing it on the server before, same result, for some reason, the executon on the pawn goes to remote... i feel like i am doing somethig with interfaces that i am not suppose to do..

I guess I don't understand what "the executon on the pawn goes to remote" means

Somehow the Inteface call is executing on the Client?

stiff rapids Jan 21, 2017, 10:37 PM

#

@ocean dust for simplicity i am executing much on client right now. let me try explain

ocean dust Jan 21, 2017, 10:39 PM

#

Any other Steam integration guides out there that are correct for 4.14.3?

stiff rapids Jan 21, 2017, 10:45 PM

#

@ocean dust the fire weapon logic, it just finds any actor attached to my pawn, that implements a weapon interface, then it send the "use" message. The use message gets to my weapon actor, its fires the event use, which does a trace, if it hits a actor witch in its turn has a interface called on hit implemendet. the weapon sends onhit interface message to that actor. Now, the last actor witch recivies the onhit messages, fires onhit event, this event takes "health variable", says to authority to decrease it by some ammount. Healt variable is onrep notify. This onrep notify chages some text. If the OnHit interface call is made from the weapon as i want, is authority fails on the last actor, it goes to remote. If onHit is called from pawn directly with asimple trace, the last actor decreses its variable trough authority... sorry if i am unable to explain this clearly..

ocean dust Jan 21, 2017, 10:47 PM

#

That all makes sense

#

With one issue: You are running all of this logic on the Client

#

You need to add a new Custom Event, set it to Run on Server Reliable

#

And call that event from your InputAction

stiff rapids Jan 21, 2017, 10:50 PM

#

yeah i get what you mean, this is the path i went from the beginning, and still failed. But turth to be told, i might have overlooked something, so i am going to try and rewire it again so it server side. One question, if i fire the first interface call "Use" from my pawn but run on server, does the rest of the chain execute on the server too?`

ocean dust Jan 21, 2017, 11:05 PM

#

Yes. If the Custom Event that starts the logic has "Run on Server" then it will be running on the server

stiff rapids Jan 21, 2017, 11:09 PM

#

Amazing, just got it to work now, by doing as you said. Thank you. Much appriciated. THe interesting part is, the only difference now is that before all this, i was running the run on server logic on the weapon, it started there with the raytrace... now instead, i just run it even before that...

#

I am guessing that the sideeffect of having all running on server is that i cant see the raytrace debug info from the client view now, but that is expected i guess?

ocean dust Jan 21, 2017, 11:23 PM

#

Uh hmm. I guess? I set up similar logic for my game to run on both cient and server for some lag prediction (but I'll probably drop the client logic)

stiff rapids Jan 21, 2017, 11:31 PM

#

Sure looks like that right now, as everything is server side, when the client shoots, the trace debug is drawn only on server(listen). I am still confused as to why it didnt work before when it was client side trace... i know its no good client side, but confusing it worked from pawn but not from attached actor. anyways, thanks.

smoky ore Jan 21, 2017, 11:57 PM

So, My client cant see it's animation but the server can, and my server can see it's animation but the client can't. I am using am using an anim montage, are there certain things you have to do with anim montages when it comes to replication?

#

my code is currently setup like this

#

{
    if (Role < ROLE_Authority)
        ServerReloadWeapon();

    else
        ReloadWeapon();
}```

#

and all what reload weapon does is just play a animation

hallow shore Jan 22, 2017, 12:00 AM

#

you need to multicast animation

#

i dont know c++ term from it

smoky ore Jan 22, 2017, 12:03 AM

#

would the reload animation need to be replicated as well?

brittle sinew Jan 22, 2017, 12:06 AM

#

Yes, you need to play the reload animation on all clients

#

Make a NetMulticast RPC and call that from the server, which just calls the animation

#

Working in MP, you have to realize that most stuff needs to get called on all clients if you want everyone to see it. Things like AnimBPs exist on all clients so they work fine, but manually playing animations needs to be called multicast

thin stratus Jan 22, 2017, 12:09 AM

#

Things like shooting and reloading are normally handled like this:

#

Client Pressed Button to Reload -> That moves the call to the Server with a ServerRPC and also does the same on the Client that pressed the button

#

You want instant reaction for the Client that presses the button, so he takes care of playing the Animation himself

#

On the ServerSide, you simply perform all the math behind reloading and multicast the reloading animation to the other clients

#

Filtering the original client in the Multicast call as you don't wanna do that twice

#

ServerRPC -> Reload the Weapon (math) -> Multicast -> Play Reload Animation (but not on the weapon instance that is on the original client)
/ 
Client Press Reload 
\
Client Call -> Reload the Weapon (math) (Yes, you could technically cheat here, but the ammo is still replicated and shooting shoot be checked on the server!) -> Play Animation

nova wasp Jan 22, 2017, 12:20 AM

Is there a way to set the extra windows for the other clients to appear spread out when you start playing with multiple players?

Something simple like allowing a website user to select the music that plays for a player

wary willow Jan 22, 2017, 1:49 AM

probably something like VAREST, JSON, anything that will allow you to communicate externally with a server @vivid siren

Yeah, looks like you can get request objects from server

Hey guys, I have a question that I'm going to try to explain. I have a projectile spawning on the server and replicating and its amazing and thanks to the resources you guys sent me i got it working. The only problem is that for some reason, the projectile isn't firing anywhere near my crosshair. But if I fire the projectile on the client with the same exact values, it goes exactly where i want it

#

Does it have to do with the UGameplayStatics::BeginDeferredActorSpawnFromClass() function maybe?

#

LogTemp:Warning: CLIENT ROTATION:   X=0.916 Y=0.399 Z=0.047
LogTemp:Warning: CLIENT SPAWN:   X=1831.037 Y=798.989 Z=94.453
LogTemp:Warning: SERVER ROTATION:   X=0.916 Y=0.399 Z=0.047
LogTemp:Warning: SERVER SPAWN:   X=1352.710 Y=1462.012 Z=180.821

I'm multiplying the forward vector of the rotation by 2000 and setting that to be the Velocity of the projectile's movement component.

brittle sinew Jan 22, 2017, 3:48 AM

#

Are you doing the trace that decides where the spawn occurs on the server?

#

If so, you might be battling latency issues, but that far off seems unrealistic for that

obtuse zinc Jan 22, 2017, 3:50 AM

#

No, I'm calling GetSightRayHitLocation from the playercontroller on the client, but even when I'm standing still they are way off

brittle sinew Jan 22, 2017, 3:50 AM

#

Is that a function you wrote?

obtuse zinc Jan 22, 2017, 3:52 AM

#

Yeah it is, sorry lol. Forgot i did. It's just a function that shoots out a cast from the crosshair and checks what it hits

#

or where, rather

brittle sinew Jan 22, 2017, 3:53 AM

#

So you're calling the authoritative trace on the client, and the values aren't the same on the server? Based on the logs you posted up there

#

And why are you getting the trace hit location if you're just using the rotation's forward vector to spawn it? I'm not entirely following 😛

obtuse zinc Jan 22, 2017, 4:01 AM

#

Well I'm basically using it to see if I'm aiming at something, and if I am then I set the rotation to be the rotation between the spawnpoint and the hitlocation, otherwise I'm just shooting it in the direction that my character is facing

#

// Returns true if hit something, and HitLocation is pass by reference
if (PC->GetSightRayHitLocation(HitLocation))
        {
            // Setting up the rotation and location of the spawn point for the rocket
            Location = GetActorLocation() + (GetActorForwardVector() * 100);
            Rotation = (HitLocation - (Location)).Rotation();
        }
        else
        {
            // Setting up the rotation and location of the spawn point for the rocket
            Location = GetActorLocation() + (GetActorForwardVector() * 100);
            Rotation = GetControlRotation();
            Rotation.Pitch += 1.f;
        }

        FTransform ProjectileTransform = FTransform(Rotation, Location);

        ServerFireProjectile(ProjectileTransform);

#

And those logs are printed immediately after spawning the rocket on the server and on the client. The rotation of the rocket is the same in both circumstances, but when it sets the velocity of the rocket, they are different for some reason

#

MovementComp->Velocity = ShootDirection * MovementComp->InitialSpeed;

ShootDirection is the "CLIENT/SERVER ROTATION" log above

brittle sinew Jan 22, 2017, 4:07 AM

#

Where are you getting ShootDirection from? If it's calculated on the client, it should be the same on the server...?

obtuse zinc Jan 22, 2017, 4:11 AM

#

Yeah ShootDirection is calculated on the client, and it's the same on both the client and the server

FVector ShootDirection = ProjectileTransform.GetRotation().GetForwardVector();

brittle sinew Jan 22, 2017, 4:31 AM

#

Where is the location coming from then, the ProjectileTransform? If you're just taking the client's value, it would be odd if it was just different on the server

obtuse zinc Jan 22, 2017, 4:46 AM

#

// Returns true if hit something, and HitLocation is pass by reference
if (PC->GetSightRayHitLocation(HitLocation))
        {
            // Setting up the rotation and location of the spawn point for the rocket
            Location = GetActorLocation() + (GetActorForwardVector() * 100);
            Rotation = (HitLocation - (Location)).Rotation();
        }
        else
        {
            // Setting up the rotation and location of the spawn point for the rocket
            Location = GetActorLocation() + (GetActorForwardVector() * 100);
            Rotation = GetControlRotation();
            Rotation.Pitch += 1.f;
        }

        FTransform ProjectileTransform = FTransform(Rotation, Location);

It's all jsut coming from the client. And the rotation value is the same for both, but when I shoot the projectile they go in different directions lol. Maybe there's a weird collision thing happening?

brittle sinew Jan 22, 2017, 4:47 AM

#

Well, the logs you posted showed two clearly different locations, when are you logging that? From the client's info or from after it's spawned?

#

Because that wouldn't be a collision issue if you're just logging the info that came from the client 😛

ocean dust Jan 22, 2017, 4:54 AM
