There are other situations like a button (like you said) could benefit from fast as possibvle arrival, even if the order is different

graceful zephyr Jun 16, 2020, 12:39 PM

#

@solar garden reliable un-ordered is useful for everything which doesn't need an order lol

#

also you don't use reliable ordered for commands (if you mean like player input commands in an auth simulation)

solar garden Jun 16, 2020, 12:42 PM

#

I was thinking more of server commands, player inputs are sent unreliably ?

empty quiver Jun 16, 2020, 1:12 PM

Can someone explain to me how UI works with the photon plugin please

gleaming prawn Jun 16, 2020, 1:19 PM

You should ask more specific questions.

Thank you for the advice it turns out it was nothing to do with Photon

Creating custom networking with TCP/UDP sockets for learning purposes. Do y'all think it'd be a good idea to create a new thread for server-client communication in the client wherein all its Connect/Receive/Send stuff are blocking? As opposed to using stuff like socket.BeginConnect and I think socket.BeginReceive which accept callbacks.

slim ridge Jun 16, 2020, 4:15 PM

#

depends on the rest of your client. if it's using async features your sockets should too. otherwise i recommend threads

open trench Jun 16, 2020, 9:21 PM

#

alright, thank you!

#

I decided to go with a thread, doing UDP stuff

#

Assuming a game server is underloaded & ends up having plenty of CPU cycles to spare etc, are there any strong reasons for why you'd still want to limit receiving player state/event datagrams from every client (and using it to update server/authoritative state) to some fixed rate?

#

Like any strong reasons to design game servers to ignore (some) datagrams if they reach some absurd rate from some clients despite the server easily being able to handle the rates collectively?

slim ridge Jun 16, 2020, 9:32 PM

#

plenty i'm sure. Best one I can think of is to eliminate spam from compromised clients or bots

#

but im pretty sure the DNS providerand network firewalls can take care of most of that

open trench Jun 16, 2020, 9:34 PM

#

so there's not much reason to design such a limit into your game server?

#

i.e. the DNS and networks will fix that for you?

slim ridge Jun 16, 2020, 10:10 PM

#

wow my tick based state sync just worked for the first time.

I was wandering If anyone could assist me with C# firebase for a unity project (I just need to know how to return a token to my backend)
right now the return type is firebase.auth.firebaseuser and I don't know how to best convert this into JSON because everytime I do it is returned empty (I assume it is a promise return issue but I'm no familiar enough with C#)
please ping me if you can assist, I can also pay for your time if that's allowed.

Hi, can anyone explain my why using structs with Sequential Layoutkind and Pack 1 and using marshalling to create a byte arry of it ends up with different results on Windows and Android ?

#

Thats part of my test code ```cs
[StructLayout(LayoutKind.Sequential, Pack = 1)]
struct ExampleStruct
{
public byte byte1; //76
public float float1; //123456.12345f
public int integer1; //8763
}

var size = Marshal.SizeOf(example);
var arr = new byte[size];
var ptr = Marshal.AllocHGlobal(size);
Marshal.StructureToPtr(example, ptr, true);
Marshal.Copy(ptr, arr, 0, size);
Marshal.FreeHGlobal(ptr);```

#

and the resulting byte arrys

#

Windows : [76,16,32,241,71,59,34,0,0] vs Android :[16,32,241,71,0,59,34,0,0]

gleaming prawn Jun 17, 2020, 7:50 AM

#

Sequential is not guaranteed to have the exact same padding

#

In different platforms

#

Explicit layout would do it AFAIK

graceful zephyr Jun 17, 2020, 10:12 AM

#

@weak lava padding is not the same between platforms/compilers/etc.

#

Pack=1 just means "please attempt to this on 1 byte boundries"

#

but if the platform doesn't support it

#

or the compiler thinks different

#

no dice

#

additionally Marshal specifically deals with interacting with the native ABI for the platform, which is not the same between different archs/etc.

#

basically sequential + pack is useless for ensuring same memory layout everywhere

#

it's 100% legitimately absolute no use what so ever

#

sizeof(Foo) and Marshal.SizeOf(typeof(ExampleStruct)) isn't even guaranteed to return the same value

weak lava Jun 17, 2020, 10:25 AM

#

@gleaming prawn @graceful zephyr Thanks for the informations.

graceful zephyr Jun 17, 2020, 10:26 AM

[StructLayout(LayoutKind.Sequential, Pack = 1)]
struct ExampleStruct
{
  public byte byte1; //76
  public float float1; //123456.12345f
  public int integer1; //8763
}

ExampleStruct example = new ExampleStruct();

unsafe {
  byte* exampleBytes = (byte*)&example;
  for (int i = 0; i < sizeof(ExampleStruct); ++i) {
    Debug.Log($"{i}: {exampleBytes[i]}");
  }
}

@weak lava

#

this is how to print/access the bytes w/o Marshal

#

but even if this turns out same in your case on windows/android, it doesn't matter

#

because it wont work for every case, and is basically useless

#

you need control layout by hand

#

INCLUDING manual padding bytes

gleaming prawn Jun 17, 2020, 10:29 AM

#

lol... I like it (explicit)... Some padding gaps are super nice to fit in extra data when things start to get data-hungry....:)

weak lava Jun 17, 2020, 10:39 AM

#

ah ok that means with the use of Explicit and a defined layout, the results should be equly on differen systems ? like so cs [StructLayout(LayoutKind.Explicit)] struct ExampleStruct { [FieldOffset(0)] public byte byte1; //76 [FieldOffset(1)] public float float1; //123456.12345f [FieldOffset(5)] public int integer1; //8763 } Tha feels like a lot of noise for my scenario and im already using a different approach, but it is good to know how all that stuff works^^

graceful zephyr Jun 17, 2020, 10:42 AM

#

@weak lava that layout looks pretty bad, as u will have unaligned read on both float and int

gleaming prawn Jun 17, 2020, 10:45 AM

#

[StructLayout(LayoutKind.Explicit)]
struct ExampleStruct
{
    [FieldOffset(0)]
    public byte byte1; //76
    // afaik floats are 4-byte aligned
    [FieldOffset(4)]
    public float float1; //123456.12345f
    // same for Int32
    [FieldOffset(8)]
    public int integer1; //8763
}

#

you have 3 extra bytes (of padding) if you need some 3 new bytes

weak lava Jun 17, 2020, 11:06 AM

#

ah ok ^^makes more sense

viscid tree Jun 17, 2020, 1:15 PM

#

is photon safe enough to publish in webgl?

#

on the web*

gleaming prawn Jun 17, 2020, 1:15 PM

#

Does it work with WebGL (I asume PUN, as photon has several different products)? Yes

viscid tree Jun 17, 2020, 1:16 PM

#

??

gleaming prawn Jun 17, 2020, 1:16 PM

#

What is your exact question?

#

What do you mean by safe enough?

viscid tree Jun 17, 2020, 1:16 PM

#

like is it safe from hackers?

#

or does it depend on something

graceful zephyr Jun 17, 2020, 1:16 PM

#

that's not how any of that works, ever.

#

like.. ever

viscid tree Jun 17, 2020, 1:16 PM

#

ok

#

im fairly new with photon

#

well, is it safe to publish?

#

thx

gleaming prawn Jun 17, 2020, 1:18 PM

#

safe to publish? I do not know what this question means

#

Sorry

#

Does PUN (as I said, photon is a company, not a product alone, there are several different photon products) protect against hacking out of the box?

#

Not much/not really

#

It's based in full client authority

#

It's very convenient for you to develop with though

weak plinth Jun 17, 2020, 1:20 PM

#

anyone have s solution for my game that requires a friend(online) list/ pre-game lobby feature like csgo and fortnite where you wait and queue with friends?

viscid tree Jun 17, 2020, 1:33 PM

#

@gleaming prawn thanks 1 more question, is pun2 more secure than pun1

gleaming prawn Jun 17, 2020, 1:34 PM

#

no

#

It's the same approach

#

Photon Bolt is traditional client server (server authority), quantum is deterministic

#

These are safer against "hacking" (depdends what you consider here as well)

vagrant marten Jun 17, 2020, 1:55 PM

#

anyone have s solution for my game that requires a friend(online) list/ pre-game lobby feature like csgo and fortnite where you wait and queue with friends?
@weak plinth Hey buddy. You'll need to have a always active server : this has to be a server that responds at any time a client tries to connect to it. When the game is launched, you'll need to connect to this server and it'll give you the infos about your friend's list/ server's list. You can buy a server like that (not much a month), and you'll have to configure it all by yourself.

frozen fog Jun 17, 2020, 2:35 PM

#

if it is serverless way it can help too

#

if it is active then it dont go cool so not waking up so much but if need always be up then you might need to think of keep alive or being warm up path

viscid tree Jun 17, 2020, 2:37 PM

#

true

weak plinth Jun 17, 2020, 3:10 PM

#

@vagrant marten i have a server and a database is on there i was just hoping someone already has a solution for this exact case as i dont wanna dive into sockets and such

vagrant marten Jun 17, 2020, 3:12 PM

#

@weak plinth oh sorry I didn't get you were at that point ^^ (btw this is fairly simple, when connected by tcp use server commands to just return infos, if you did networking already, don't worry you'll get it)

weak plinth Jun 17, 2020, 3:13 PM

#

I do networking with mirror for the actual gameplay because doing tcp/udp socket stuff is just annoying

#

and time consuming

#

thats why i asked.

slim ridge Jun 17, 2020, 3:19 PM

#

photon pun/bolt/quantum one of those should suit your needs

viscid tree Jun 17, 2020, 5:05 PM

#

how do i call a function from a gameobjects script that does something to that player in their view

#

example:

Script 1:
//stuff
void MethodThatDoes() {
    Debug.Log("did stuff");
}
Script 2:
//stuff
MethodThatDoes()

#

it shouldn't print "did stuff" in my console, but in their console

#

since it's their script, how is this done?

glass osprey Jun 17, 2020, 5:51 PM

#

I guess this would be the channel to discuss mmo capabilities of Unity?

#

Since networking would be the bottleneck?

gleaming prawn Jun 17, 2020, 6:30 PM

#

Have you ever shipped a multiplayer game? If yes, then yes

#

If no, then no

glass osprey Jun 17, 2020, 6:42 PM

#

This is my first time working with unity however I am developer for like 10 years and been doing "servers" that suppose to comunnicate with players

#

it's not impossible to make an MMO in unity but it's ill-advised- you don't get the level of control you need. but this conversation is better suited for another channel
@atomic ingot

#

The level of control I need is something that I'm wondering about

gleaming prawn Jun 17, 2020, 6:47 PM

#

Have you ever developed and released a multiplayer game yourself? As part of the team developing the network side of things?

#

Unity is as suited as basically any client engine is...

glass osprey Jun 17, 2020, 6:48 PM

#

No, everyone got to start somewhere

gleaming prawn Jun 17, 2020, 6:48 PM

#

Do not start with an mmo...:)

#

That's your answer.

glass osprey Jun 17, 2020, 6:49 PM

#

No I have never compromised and this time will not be any different

viscid tree Jun 17, 2020, 6:49 PM

#

hi, where can i send stuff from multiple players to a singular array which can be viewed from any player?

#

do normal arrays work? like if i made a static array variable would it work?

glass osprey Jun 17, 2020, 6:50 PM

#

I was just wondering why someone said unity is not suited for mmo, I thought netcode will be a problem

viscid tree Jun 17, 2020, 6:51 PM

#

?

slim ridge Jun 17, 2020, 6:51 PM

#

the more in depth your mmo gets, the less useful unity is.

glass osprey Jun 17, 2020, 6:52 PM

#

but are there any barriers that cannot be overcome?

gleaming prawn Jun 17, 2020, 6:53 PM

#

The more.in depth your mmo gets, the less important any engine (as a single piece of software)

#

Unity (or unreal, or your-favorite-engine) is probably 1% of what you need for an mmo

viscid tree Jun 17, 2020, 6:53 PM

#

whats an mmo

gleaming prawn Jun 17, 2020, 6:53 PM

#

So basically, wrong questions

slim ridge Jun 17, 2020, 6:53 PM

#

you wont know until you try

glass osprey Jun 17, 2020, 6:54 PM

#

when it comes to raw code, I can handle that as long as engine will let me

gleaming prawn Jun 17, 2020, 6:55 PM

#

I wonder if in 10 years it will still be the same question...:)

slim ridge Jun 17, 2020, 6:55 PM

#

first barrier i encountered was the update loop. Since you can only modify the scene from the main thread you have to use async features or pass the data between threads

#

and when it comes to networking, fixedUpdate is completely useless

glass osprey Jun 17, 2020, 6:56 PM

#

and there is no way around it?

#

And i mean proper solution not hot-glue-fix

slim ridge Jun 17, 2020, 6:57 PM

#

you have to do all of your timing in Update

gleaming prawn Jun 17, 2020, 6:57 PM

#

If you start from the assumption you will use for an mmo server, go back 10 slots, start over

#

Whatever you say about update loop is just mambo jambo, this is not even were you start...

#

There's nothing wrong with using unity as an mmo CLIENT, nothing

glass osprey Jun 17, 2020, 6:59 PM

#

well, unity is not a server side suite

gleaming prawn Jun 17, 2020, 6:59 PM

#

No engine is

glass osprey Jun 17, 2020, 6:59 PM

#

I wasn't going to use it a server, is that even possible?

slim ridge Jun 17, 2020, 7:00 PM

#

lol yes but not advised

gleaming prawn Jun 17, 2020, 7:00 PM

#

Well, for FPS games, that's normally how you do it

glass osprey Jun 17, 2020, 7:00 PM

#

no

#

ok i think i get it

gleaming prawn Jun 17, 2020, 7:00 PM

#

No, you did not getnit

glass osprey Jun 17, 2020, 7:00 PM

#

you guys thought I was going to use it as both client and server?

gleaming prawn Jun 17, 2020, 7:00 PM

#

Get it* :)

#

If you got it, you would not ask this question...:)

slim ridge Jun 17, 2020, 7:01 PM

#

i was talking about as a client

gleaming prawn Jun 17, 2020, 7:01 PM

#

Sorry, that's all I can contribute. Just a humble opinion.

#

Nothing wrong with unity in itself. Just do not start with an MMO

#

It's the same question over and the ver, I've seen it for the past 15 years

slim ridge Jun 17, 2020, 7:02 PM

#

im guessing he has already shipped some kind of online service before if he worked on servers

gleaming prawn Jun 17, 2020, 7:03 PM

#

Just do yourself a nice favour, start with a cool game, simpler one

#

One you can finish alone

#

If he would be in a position to even start discussing about what it takes.to code an mmo, he would ask different questions...:)

#

Sorry, but there's people here who can do one...

glass osprey Jun 17, 2020, 7:04 PM

#

No you are wrong, I have over 15 years of experience in development BUT i do not know much about unity

gleaming prawn Jun 17, 2020, 7:04 PM

#

Just start with something smaller you like

glass osprey Jun 17, 2020, 7:04 PM

#

no no no, sorry i have never started with small stuff, this is just boring

gleaming prawn Jun 17, 2020, 7:04 PM

#

Lil

slim ridge Jun 17, 2020, 7:04 PM

#

it's ok to have ambitions for an MMO, just be realistic about the milestones between here and there. it will be a lot of them

graceful zephyr Jun 17, 2020, 7:07 PM

#

@glass osprey start with something simple like multiplayer pong 🙂

#

If you start with an MMO, you will get like <5% of the way and then give up

glass osprey Jun 17, 2020, 7:10 PM

#

I am totally opposite of that

#

if I start with some minor stuff i get bored and quit

graceful zephyr Jun 17, 2020, 7:10 PM

#

You have no idea what you're trying to build.

glass osprey Jun 17, 2020, 7:10 PM

#

I do

graceful zephyr Jun 17, 2020, 7:10 PM

#

Then you've built it before?

#

If so, then go ahead

glass osprey Jun 17, 2020, 7:10 PM

#

not but I more or less know how this works in WoW

graceful zephyr Jun 17, 2020, 7:11 PM

#

You can't both have not built it before and know what you need to build

gleaming prawn Jun 17, 2020, 7:11 PM

#

Do you, really? :) Then why you ask here

graceful zephyr Jun 17, 2020, 7:11 PM

#

Those two are mutually exclusive

glass osprey Jun 17, 2020, 7:11 PM

#

good lord, I was asking if using unity will be a problem

graceful zephyr Jun 17, 2020, 7:11 PM

#

Yes and No

#

Probably

slim ridge Jun 17, 2020, 7:12 PM

#

lol dont come in here for encouragement

graceful zephyr Jun 17, 2020, 7:12 PM

#

Considering you've never done this before

#

Unity will be an issue for you

gleaming prawn Jun 17, 2020, 7:12 PM

#

Encouragment you can get.on the self help section of the local library...:)

#

Here's the reality of the facts

graceful zephyr Jun 17, 2020, 7:13 PM

#

You can't build an MMO as your first multiplayer project with no previous experience by yourself.

#

Simple fact.

#

If you think you can, you are delusional

#

Or it will take you so long that you will give up

#

And bare in mind I mean actual viable code that could support a launched game

glass osprey Jun 17, 2020, 7:13 PM

#

thats exactly what I am aimingfor

#

long and hard project

graceful zephyr Jun 17, 2020, 7:13 PM

#

anyone can download UMMORPG from asset store and "make" their "mmo" lol

#

so expect ~15 years or so

#

see you in 2035 or so, best of luck

gleaming prawn Jun 17, 2020, 7:14 PM

#

That's a nice name for one btw

#

Cyberwagon 2035

graceful zephyr Jun 17, 2020, 7:14 PM

#

@glass osprey But sure, unity will give you problems.

#

If you try to make an MMO fully inside of Unity

#

not adviced at all

gleaming prawn Jun 17, 2020, 7:15 PM

#

Same would be if you replace unity with ue

#

But you already said that would not be your idea

#

If you would be really serious, depending on the scale of what a single player sees and does, I do not see a big issue with unity.as the mmo game client

#

You should be worried about what you will actually use for your servers

glass osprey Jun 17, 2020, 7:17 PM

#

Honestly, I didn't ask for people opinions of what should I do or what I shouldnt. I am perfectly aware of my capabilities. Why people feel so compeled about forcing their views onto others?

gleaming prawn Jun 17, 2020, 7:17 PM

#

What would be the architecture for supporting shards, how to cope with stuff like 200.000 moving NPC's, 20k players.

glass osprey Jun 17, 2020, 7:17 PM

#

I asked if just unity is capable to work as mmo client

graceful zephyr Jun 17, 2020, 7:17 PM

#

@glass osprey Then go bother some other channel

gleaming prawn Jun 17, 2020, 7:17 PM

#

About your last question: it's called experience

graceful zephyr Jun 17, 2020, 7:17 PM

#

@glass osprey unity is that... sure, mabe, no, yes?

#

depends on what you do with it

#

just the fact that you need to ask that shows how out of your depth you are

glass osprey Jun 17, 2020, 7:18 PM

#

thats what I am talking about

#

I can do the code, both server and client

graceful zephyr Jun 17, 2020, 7:18 PM

#

You probably can't, but sure

glass osprey Jun 17, 2020, 7:19 PM

#

but thats not your problem isn't it?

graceful zephyr Jun 17, 2020, 7:19 PM

#

Nope

#

So like i said

#

Will unity work as an MMO client? yes/no/maybe

#

Depends on what you do with it

gleaming prawn Jun 17, 2020, 7:20 PM

#

If you ask a more specific technical question, maybe you can get answered as well

#

For the question you asked, the answer.is, really, honestly, don't do an MMO

glass osprey Jun 17, 2020, 7:20 PM

#

I already got one example of good answer from @slim ridge

gleaming prawn Jun 17, 2020, 7:20 PM

#

Yeah, sure

graceful zephyr Jun 17, 2020, 7:23 PM

#

@glass osprey if you want to use something to get u started look into mirror

#

https://github.com/vis2k/Mirror

#

they have a very big discord server also where u can get tons of help

viscid tree Jun 17, 2020, 7:24 PM

#

which is more protected from hackers in android ? mirror or photon

#

i really need a clear answer for this question before i start making my game

glass osprey Jun 17, 2020, 7:25 PM

#

I will be basing my networking code on WoW networking

gleaming prawn Jun 17, 2020, 7:25 PM

#

Mirror for Android means you need.to deploy dedicated servers for your game

viscid tree Jun 17, 2020, 7:25 PM

#

what does that mean

gleaming prawn Jun 17, 2020, 7:25 PM

#

We'll, here we.go

#

Have you ever developed a game before, I mean, released.one?

viscid tree Jun 17, 2020, 7:25 PM

#

yeah 3

graceful zephyr Jun 17, 2020, 7:25 PM

#

@glass osprey What does that even mean?

gleaming prawn Jun 17, 2020, 7:26 PM

#

Oh, perfect then rayan

#

Let's.go

#

With dedicated servers you need to pay.for physical machines to host every single one of your online matches

#

And that will get very very expensive

#

I do not have the mirror statistics, as I'm not one of their Devs, but I've not seen a single large multiplayer game on MOBILE done with it

#

Reason is not that it would not work,.it would...

viscid tree Jun 17, 2020, 7:27 PM

#

ahh, so the majority is done with PUN, right?

gleaming prawn Jun 17, 2020, 7:27 PM

#

It would technically work well for many games, arfuably

#

But it gets very very expensive to host servers to run an instance of unity

#

This is one of the reasons why people.go for:

pun (servers are just relay)
photon realtime + photon server plugin
quantum
forge (I assume)

graceful zephyr Jun 17, 2020, 7:29 PM

#

forge same issue as mirror

fair cosmos Jun 17, 2020, 7:29 PM

#

@viscid tree there are 2 hidden relay server transport in mirror discord check them out to

graceful zephyr Jun 17, 2020, 7:29 PM

#

¯_(ツ)_/¯

gleaming prawn Jun 17, 2020, 7:29 PM

#

Ok

#

That's nice then @fair cosmos

#

I'll make sure.to mention that next time

fair cosmos Jun 17, 2020, 7:30 PM

#

yeaH! obviously! the one relay is based on DR2 with direct connection module too!

gleaming prawn Jun 17, 2020, 7:30 PM

#

What are the relay.options? Steam for pc is one,.right?

viscid tree Jun 17, 2020, 7:30 PM

#

okay so let's say i published a decent android game with PUN2 Free and advertised it and started gaining a playerbase, will my game be vulnerable to hackers?

fair cosmos Jun 17, 2020, 7:30 PM

#

and other i didnt use

#

@gleaming prawn no a simple relay server!

viscid tree Jun 17, 2020, 7:31 PM

#

and if so, is there any way to prevent that or secure my game?

gleaming prawn Jun 17, 2020, 7:31 PM

#

Rayan, with mirror, assuming.one.of the android clients is the server, in both cases it's a bit out of your control

fair cosmos Jun 17, 2020, 7:31 PM

#

using DarkRift

#

2!

viscid tree Jun 17, 2020, 7:31 PM

#

okay one last question, can a hacker hack me by hacking my game?

gleaming prawn Jun 17, 2020, 7:31 PM

#

????

viscid tree Jun 17, 2020, 7:31 PM

#

like they can trace back the connection or sum

gleaming prawn Jun 17, 2020, 7:32 PM

#

Sorry I really did not understand your question

#

With relays, no

viscid tree Jun 17, 2020, 7:32 PM

#

you sure?

fair cosmos Jun 17, 2020, 7:32 PM

#

@viscid tree ips are hidden!

gleaming prawn Jun 17, 2020, 7:32 PM

#

With a.decent relay, no

fair cosmos Jun 17, 2020, 7:32 PM

#

client > relay > client

gleaming prawn Jun 17, 2020, 7:32 PM

#

Not possible

viscid tree Jun 17, 2020, 7:32 PM

#

whats a relay

graceful zephyr Jun 17, 2020, 7:33 PM

#

dude just give up

gleaming prawn Jun 17, 2020, 7:33 PM

#

If you want to go the route of relay based but client server, both mirror and photon bolt work

graceful zephyr Jun 17, 2020, 7:33 PM

#

for real

fair cosmos Jun 17, 2020, 7:33 PM

#

simply relay is a server which allows your player to make rooms without port forwarding(but still u have to port forward on the relay host)

gleaming prawn Jun 17, 2020, 7:33 PM

#

Port forward, really? :)

graceful zephyr Jun 17, 2020, 7:34 PM

#

@fair cosmos port forward on android? lol

viscid tree Jun 17, 2020, 7:34 PM

#

whats port forwarding

fair cosmos Jun 17, 2020, 7:34 PM

#

i say without port forwarding dude!

viscid tree Jun 17, 2020, 7:34 PM

#

yeah i know, just asking

fair cosmos Jun 17, 2020, 7:34 PM

relay host means(hosting On VPS) dud

#

e

gleaming prawn Jun 17, 2020, 7:34 PM

Hmmm

viscid tree Jun 17, 2020, 7:34 PM

#

whats VPS

gleaming prawn Jun 17, 2020, 7:35 PM

#

@viscid tree is this a real game, I mean something that you expect to be played?

#

Released commercially

#

I assume your 3 past games are real released games, with a decent track record.

viscid tree Jun 17, 2020, 7:36 PM

#

nothing in mind, i'm just looking to see if it's possible, but yeah if i think of something i'm capable of developing, publishing and advertising

sharp star Jun 18, 2020, 3:02 AM

#

with mirror, how would I use the virtual void OnServerAddPlayer? I tried making my own network manager class by doing

using UnityEngine;
using Mirror;

public class CustomNetworkManager : NetworkManager {
  public override void OnServerAddPlayer() { Debug.Log("TEST"); }
}```
but it just says `'NetworkManager.OnServerAddPlayer():' no suitable method found to override`

#

nevermind im dumb

#

i forgot the NetworkConnection conn argument

fair cosmos Jun 18, 2020, 7:27 AM

#

@sharp star go to Mirror Discord for further help!

stiff ridge Jun 18, 2020, 8:53 AM

#

You were connected first?
I assume you call Disconnect() right before setting OfflineMode = true?
Wait for the callback OnDisconnected() and try there.

stiff ridge Jun 18, 2020, 9:23 AM

#

Are you using PUN 2.18.1 (latest from asset store)?

#

Can't reproduce this in that version.

weak plinth Jun 18, 2020, 9:35 AM

#

why doesnt this rpc function work? If i put things locally above it it works fine

📎 unknown.png

#

here's the function

📎 unknown.png

#

[punRPC] is above it

stiff ridge Jun 18, 2020, 9:37 AM

#

Because you call the RPC with one parameter (the ...ViewID in the call) and you don't have a parameter in the implemented method.

#

The error log for that should indicate this (but is not worded well, I admit)

viscid tree Jun 18, 2020, 9:58 AM

#

hi, so i'm trying to change the isTrigger of a BoxCollider2D but it only changes for the player viewing, other players still see it as isTrigger, how do i overcome this?

#

do i add the BoxCollider2D component as an observable component to the photon view?

#

or do i add a photon view component to the gameobject containing the boxcollider2d

weak plinth Jun 18, 2020, 10:01 AM

#

once the if becomes true, if the conditions are correct it still doesnt happen

📎 unknown.png

#

so if it happens once, its true and when it happens again it's always false

stiff ridge Jun 18, 2020, 10:49 AM

#

RPCs are executed on a specific ViewID. You call photonView.RPC(...). That's enough to keep the context and you don't need to pass the viewID as parameter.

#

@viscid tree, Triggers are tricky. Code in Update() can not always reliably detect them, so you have to take special care to actually send them.

#

Most networking solutions have some way to specifically record triggers to send them.

viscid tree Jun 18, 2020, 10:51 AM

#

ahh okay, so what do i do then?

#

also i fixed the problem but i want to see if there's a different solution

sick cape Jun 18, 2020, 11:16 AM

#

I've been working on my multiplayer game for 7 months now 😅

#

I miss coding singleplayer ngl, so Im looking forward to finishing it

stiff ridge Jun 18, 2020, 11:22 AM

#

@viscid tree, create a cache for triggers. serialize them along with other updates, send and repeat.

viscid tree Jun 18, 2020, 12:55 PM

hey, so this isn't much of an issue but more like looking for a better method.
so everytime i test my game and stuff i build to standalone which takes about 2 minutes and i run the game in unity & standalone to simulate multiple players, it works but i literally get like 4 fps and it's so slow, is there a better way of doing this?

weak plinth Jun 18, 2020, 1:35 PM

ok

#

can anyone help please?

#

is there a more efficient way of testing multiple players
like preferably in the editor itself ?

oak flower Jun 18, 2020, 1:58 PM

#

@viscid tree What do you mean by testing multiple players?

viscid tree Jun 18, 2020, 1:58 PM

scroll up i explained the question more clearly

If you want your question answered don't make people hunt down for it. Formulate it in one place.

coral wadi Jun 18, 2020, 1:59 PM

Downgrade your graphics or optimize your code

#

Profile to see what's taking long

#

But if your world is relatively simple and your code is as well then your PC is just too shit

viscid tree Jun 18, 2020, 2:00 PM

#

my question is how do i run unity for different players in the editor itself without building to standalone

#

like i simulate player1 in a tab and player2 in a tab

oak flower Jun 18, 2020, 2:01 PM

#

Test network code on the build that uses placeholders then, to have minimum build time.

viscid tree Jun 18, 2020, 2:01 PM

#

for photon

#

the buuild time isn't the problem but is there a way for unity to do that

coral wadi Jun 18, 2020, 2:02 PM

#

Idk what photon provides, lots of people do builds to multiplayer specific things

gleaming prawn Jun 18, 2020, 2:02 PM

#

The EDITOR is heavir than a build

#

By a LOT

#

To test two "players" (you probably mean game clients) you need two instancews of the game

spring crane Jun 18, 2020, 2:02 PM

#

I guess he wants to run 2 player instances on the same client. Sort of coop.

viscid tree Jun 18, 2020, 2:02 PM

#

like 2 player instances in the unity editor itself

gleaming prawn Jun 18, 2020, 2:02 PM

#

You can either do like you are doing:

build vs editor
or use symlinks to run two editors of the same project

#

But that would be HEAVIER than what you have now

oak flower Jun 18, 2020, 2:03 PM

#

This is how Overwatch looked. https://www.youtube.com/watch?v=6sWKEkdcf48

gleaming prawn Jun 18, 2020, 2:03 PM

#

like 2 player instances in the unity editor itself
Unity editor does not let you run two instances of the game

#

In PUN, or Mirror, or many of these libs, what you test are two game clients (game instances). Player is just mapped (most of the time) 1-1 with game client

#

The lighter you can do is:

test with two game builds, run them in shitty quality settings, IL2CPP builds

viscid tree Jun 18, 2020, 2:05 PM

#

IL2CPP is for webGL only right?

gleaming prawn Jun 18, 2020, 2:05 PM

#

But I suspect it's your code that is currently too heavy

#

No... IL2CPP does not exist in Webgl

#

IL2CPP is the only honestly usable runtime for Unity for production

#

But anyway

#

Just for testing, mono builds should be fine

viscid tree Jun 18, 2020, 2:05 PM

#

i mean i literally have no graphics at all just a bunch of squares and like 2 ui text elements

gleaming prawn Jun 18, 2020, 2:06 PM

#

You either have a very very heavy code (yours) or a very very very bad computer

#

i mean i literally have no graphics at all just a bunch of squares and like 2 ui text elements
It's not the graphics, it's the CPU probably

#

Use the Unity profiler

#

identify what is running so slow in the first place

viscid tree Jun 18, 2020, 2:06 PM

#

i did, it had a lot of green and a tiny bit of blue

#

does that mean the cpu is slow?

gleaming prawn Jun 18, 2020, 2:07 PM

#

i did, it had a lot of green and a tiny bit of blue
???

#

Do you know how to read/use a profiler?

viscid tree Jun 18, 2020, 2:07 PM

#

nevermind, sorry

#

Do you know how to read/use a profiler?
nope

gleaming prawn Jun 18, 2020, 2:08 PM

#

It will show you how long each piece of your code takes to execute in the editor

#

Try to read the Manual about it

#

Profiling is a basic programming concept

#

You need it

viscid tree Jun 18, 2020, 2:08 PM

i'll look into it, thank you!

Valve's networking in Source might be interesting https://developer.valvesoftware.com/wiki/Source_Multiplayer_Networking

jade glacier Jun 18, 2020, 5:00 PM

#

The tick stuff itself is mainly just about numbering state/inputs and using that as the backbone for syncing

#

messaging <> state & input buffers <> simulation is the concept.

#

The change on thinking is focusing on reducing you game to a tick based simulation... The rest follows that.

oh, .NET doesn't distinguish between client and server sockets the same way.
You create a Socket with various options.

I'm using Photon 2 to network. I notice that there is some lag between the time when I enter a command on the build window and when I see the corresponding action take place in the editor (and vice versa). Is there a way to cut down on this lag, or do I just have to deal with it? My game needs low lag for pvp (think about how much rage people feel when they are hit with online lag). Actions like movement and jumping also see a few frames of lag, but lag is very obvious when comparing this arrow, which has a PhotonTransformView that should sync it across computers.

Hello guys im trying to figure how can i connect to my server build from a client

I followed the manual of NetCode, but i ca get it working using my game as client and server,
What i want to do is to have a server build so connect from different clients,
but i am not able to figure how to do that

Also the networkEndPoint let you et the port but not a custom IPV4 Address, so i will not be able to set my server in a custom ip

the manual doesnt explain anything about server builds
just that can be done!

what i just want to do is to be able to move a cube throug a client that connects to the server, and be able to connect other clients to it and each of them move a cube

@marsh bison Things that need to be approved by the masterclient are problematic, since you need to hop through the relay to another client and back instead of just connecting to the server.

#

If you are just telling other clients something and not waiting for a response, then it's just normal internet latency stuff

That android app needs to connect with another hardware on my local network. So I want to know what’s the IP address of that hardware . I’ll use that IP address of hardware to send rest calls

jade glacier Jun 21, 2020, 3:48 PM

#

What is the "hardware" in question?

#

You said running from Unity, so I assumed you meant the editor.

#

If you want android devices to find one another, you will have to implement some kind of network discovery. But if the "server" is a fixed machine... just get that local IP address from its settings.

shell talon Jun 21, 2020, 3:54 PM

#

This is the device https://github.com/aromajoin/controller-http-api/blob/master/README.md

GitHub

aromajoin/controller-http-api

The documentation for HTTP API interacting with Aroma Shooter (second generation) - aromajoin/controller-http-api

#

I want to get the IP address automatically

jade glacier Jun 21, 2020, 3:55 PM

#

automatically can mean anything really

shell talon Jun 21, 2020, 3:56 PM

#

I don’t want user to search ip. Or if I can get all the ip addresses on my local network

#

I can show in the drop down box

jade glacier Jun 21, 2020, 3:56 PM

#

It sounds like you want network discovery of some kind

shell talon Jun 21, 2020, 3:56 PM

#

Yes

#

Network discovery via unity for android

jade glacier Jun 21, 2020, 3:57 PM

#

yup, Network Discovery is the answer

shell talon Jun 21, 2020, 3:57 PM

#

Do you know any weblink to do that?

jade glacier Jun 21, 2020, 3:57 PM

#

Won't work on wans/lans that block it

#

I could google it for you

shell talon Jun 21, 2020, 3:57 PM

#

Ok

jade glacier Jun 21, 2020, 3:57 PM

#

but that would be embarrassing for both of us 😛

shell talon Jun 21, 2020, 3:57 PM

#

😬

#

I m also trying to find out

#

Using C# only .

jade glacier Jun 21, 2020, 3:58 PM

#

Look at the old Unet NetworkDiscovery for some ideas

#

Or what mirror has

#

it isn;t sure to work, but it is one way to "find" other games on a lan/wan

shell talon Jun 21, 2020, 3:59 PM

#

Ok

#

On the other end , it’s not mine code.

Have you opened routers configuration page? It shows all the ip addresses that are connected

jade glacier Jun 21, 2020, 4:00 PM

#

Yeah, you tend to do that often with networking. Usually to open a port to your server.

shell talon Jun 21, 2020, 4:02 PM

#

Yes . But how to do that with unity. I’ll search more. I’ll update you if I’ll get some success 😎

#

Have you worked on iOS app ?

jade glacier Jun 21, 2020, 4:07 PM

#

yeah, my one learning game was android/ios

#

https://play.google.com/store/apps/details?id=com.emotitron.TeapotAvenger&hl=en_US It wasn't networked though. I did start a MP Descent 2 style shooter that I did test to run on iOS using the old Unet HLAPI though, which was working pretty well.

@spring crane Is there a faster/better way that would cut down on the lag? A setting I should change?

spring crane Jun 21, 2020, 4:47 PM

#

There are calls you can do to tell PUN to send everything asap, but it doesn't affect everything IIRC.

marsh bison Jun 21, 2020, 4:48 PM

#

Does it affect position, rotation, and object instantiation/destruction?

spring crane Jun 21, 2020, 4:51 PM

#

I don't remember. Could also try adjusting how much PUN buffers before sending

marsh bison Jun 21, 2020, 4:58 PM

#

@spring crane How could I change the amount the PUN buffers? I tried increasing and decreasing PhotonNetwork.SendRate and PhotonNetwork.SerializationRate but I wasn’t sure it did anything.

jade glacier Jun 21, 2020, 5:02 PM

#

You can call service on the transport at any time, but it isn't likely the source of latency.

#

PUN2 is a relay based system, meaning all traffic goes to the relay server, and that sends the messages to each player.

#

PhotonNetwork.NetworkingClient.Service(); will tell your client to push anything in the hopper out the door. But that in most cases is gaining you a small number of milliseconds if anything.

marsh bison Jun 21, 2020, 5:21 PM

#

Should I call that at the end of my update functions? How do other multiplayer games, like FPS games, get everything to sync so closely? (for the most part).

jade glacier Jun 21, 2020, 5:21 PM

#

As your netcode gets better, you will find you keep ADDING latency. Buffers are how you make the jitter of the internet not show up for users.

#

It is a bigger question than that. Update should have nothing to do with Networking - networking should all be based on Fixed timings, but generally speaking that is as quick as you can get anything out the door regardless.

marsh bison Jun 21, 2020, 5:22 PM

#

Everything should be in FixedUpdate ?

jade glacier Jun 21, 2020, 5:22 PM

#

I would be less concerned about flushing every update, and more concerned about getting your entire game state compressed down into one byte[]/packet in whatever way you can.

#

Bigger question than I can answer here in a few lines. It is the core of networking simulations.

#

You are just learning, so right now you are just using messaging to transmit and apply states.

#

Which ultimately is wrong and you will throw it all out, but you have to go through that step first.

marsh bison Jun 21, 2020, 5:26 PM

#

If I want the player to move right when they press ‘d’, how should I get them to move on all computers? Currently, I have an if(PV.IsMine), a key checker, and a force on the player, which has a photo viewer, photon transform viewer, and photon rigidbody2d viewer. It works, but it has noticeable difference between screens.

jade glacier Jun 21, 2020, 5:31 PM

#

only use one one those, not both.

#

Both are just meant to show you how to code a sync though, and aren't actually considered production tools.

#

The latency is the internet. The internet IS latency. That is the heart of game networking and why it is difficult.

#

It isn't just copying values over the network, it is about hiding that latency of the internet from users, and it is a massive complicated topic.

marsh bison Jun 21, 2020, 6:10 PM

#

@jade glacier Should I remove the photon transform? I thought that since unity’s physics is not deterministic the positions would get out of sync.

jade glacier Jun 21, 2020, 6:55 PM

#

Use whichever sync gets you the best results.

boreal cedar Jun 21, 2020, 8:53 PM

is there no networking support right now for Unity?

how do i store data inside an array from a player that can be later acquired from any other or the same player?

high night Jun 22, 2020, 11:59 AM

#

@viscid tree you can either control all entries and deletions via rpcs or see if your networking solution has synced arrays/lists

viscid tree Jun 22, 2020, 12:02 PM

#

RPCs are so confusing, i did it and literally can not figure out how to access it back again from a different script

weak plinth Jun 22, 2020, 12:06 PM

#

this line of code doesnt affect the local player tied to that variable. How do i make it so it does?

📎 unknown.png

#

its confusing to explain only decreases that variable relative to the client the game is being played on

empty quiver Jun 22, 2020, 12:49 PM

#

Id put it inside an rpc function that is called to all players therefore every client will know the health value of that player as well as the player

weak plinth Jun 22, 2020, 12:58 PM

same prefab

have u trued "colplayerscript.currentHealth -= 1"?

i'll try that

no now the variable doesnt even change on either side

@empty quiver

empty quiver Jun 22, 2020, 1:23 PM

#

either side?

weak plinth Jun 22, 2020, 1:23 PM

the variable doesnt change

#

my issue isnt that the function isnt happening, its that the variable is only decreased for the local player

empty quiver Jun 22, 2020, 1:24 PM

#

can u explain how its suppose to work in relation to the game?

weak plinth Jun 22, 2020, 1:25 PM

#

so if a player hits another player, one health is taken away. If the health = 0 the player dies

#

lets say each player has 3 health, but now if player 1 hits player 2 twice, player 3 will still need to hit player 2 3 times before they die

#

i want it so if player 1 hits player 2 twice and player 3 hits player 2 once, player 2 will die

viscid tree Jun 22, 2020, 1:27 PM

why am i getting this error?

@empty quiver

so if a player attacks another player that value of the player who they just hit isn't synced to everyone else?

#

is everyone in the scene at the time the first player is hit?

@weak plinth

yes

it shouldnt matter if everyone is in the scene @empty quiver

yea but the variable should be synced with everyone else at all times right?

but for the other ppl who joined it wont be synced for them even if its synced to the main player

thats my understanding

all players are present btw

but how do i make the variable constantly synchronised?

only for that one line of code

I'm pretty busy working on Pun2 at the moment (ironically) so can't promise I can help. Keep the question as simple as possible if you would.

weak plinth Jun 22, 2020, 1:42 PM

#

thats as simple as i can get it

jade glacier Jun 22, 2020, 1:43 PM

#

There are two colliding players though, so already a bit lost. Might be better to define them as local player, remote player, and owner.

weak plinth Jun 22, 2020, 1:43 PM

#

oh okay

jade glacier Jun 22, 2020, 1:44 PM

#

First step regardless is determine your authority structure

#

who has authority over what state values?

#

Who determines damage? And who broadcasts that damage, vs who broadcasts the damage results.

weak plinth Jun 22, 2020, 1:44 PM

#

local player collides with remote player, variable only changes for local player

jade glacier Jun 22, 2020, 1:44 PM

#

What is the variable?

weak plinth Jun 22, 2020, 1:44 PM

#

the player that collides with the other is the player that determines damage

#

health

jade glacier Jun 22, 2020, 1:44 PM

#

And who has authority over this variable?

#

So the local player has authority over its own health

#

Who has authority over damage inflicted?

#

The other player?

weak plinth Jun 22, 2020, 1:45 PM

#

local player changes the variable for the remote player

jade glacier Jun 22, 2020, 1:45 PM

#

Back that up

#

you have to define your authority, or I can't help

#

Who defines the damage?

#

Each player determines damage for themselves? Or do other players send "I damaged player X"

weak plinth Jun 22, 2020, 1:47 PM

#

local player inflicts the damage to the remote player

jade glacier Jun 22, 2020, 1:47 PM

#

So the attacker defines damage

weak plinth Jun 22, 2020, 1:47 PM

#

yes

#

📎 unknown.png

jade glacier Jun 22, 2020, 1:47 PM

#

How is the attacker defined?

#

Is there an actual attack?

weak plinth Jun 22, 2020, 1:47 PM

#

yep, its a midair boost

jade glacier Jun 22, 2020, 1:48 PM

#

Ok, so the conversation starts with the attacker RPCing out "I hit player X for X damage" or whatever

weak plinth Jun 22, 2020, 1:48 PM

#

yes

jade glacier Jun 22, 2020, 1:48 PM

#

You can target that player, or broadcast to all.

weak plinth Jun 22, 2020, 1:48 PM

#

i broadcast to all

#

it gets the script from the player it collides with and spawns a particle

jade glacier Jun 22, 2020, 1:49 PM

#

Attackee gets that RPC and locally triggers a damage method of some kind. That in turn causes a health change. The Attackee then broadcasts "My health is now X"

weak plinth Jun 22, 2020, 1:49 PM

#

and tries to decrease the health

#

i think?

#

can i just show you my code?

jade glacier Jun 22, 2020, 1:49 PM

#

You are welcome to look at the SNS beta, it does all of this

#

But its not an easy read

#

If your code is easy to read I can look

#

But I literally am at work right now, so I am already WAY longer into this than I can afford to be

#

The conversation you are after is
Attacker RPCs out "I hit player X"
Attackee gets RPC... applies damage to health... RPCs out "My health is now X"

weak plinth Jun 22, 2020, 1:51 PM

#

📎 unknown.png

jade glacier Jun 22, 2020, 1:51 PM

#

Way too little context there to know if that conversation is happening or not in your code

weak plinth Jun 22, 2020, 1:51 PM

#

it does happen

jade glacier Jun 22, 2020, 1:51 PM

#

Then it should work, unless you have a bug in your code

weak plinth Jun 22, 2020, 1:52 PM

#

but the damage and audio only happens for the local player

jade glacier Jun 22, 2020, 1:54 PM

#

Are the RPCs firing correctly at least?

weak plinth Jun 22, 2020, 1:54 PM

#

how can i check that?

#

as far as i know, yes

jade glacier Jun 22, 2020, 1:54 PM

#

Debug.LogError("I Did a thing");

weak plinth Jun 22, 2020, 1:54 PM

#

the particle is spawned for both local player and remote player

jade glacier Jun 22, 2020, 1:55 PM

#

If the RPCs are firing as expected, then its other non-networking code that is the problem

#

if the RPCs aren't firing, then there is an issue with your targets or logic.

weak plinth Jun 22, 2020, 1:55 PM

#

okay so its the non networking code?????

jade glacier Jun 22, 2020, 2:00 PM

#

Depends if the RPCs are firing correctly or not

weak plinth Jun 22, 2020, 2:03 PM

#

this is what happens

📎 unknown.png

#

colplayerscript.currentHealth = colplayerscript.currentHealth - 1;
is the thing thats mucking up

#

@jade glacier Debug.LogError("I Did a thing"); is called but the problem still persists

jade glacier Jun 22, 2020, 2:14 PM

#

If the RPC is firing as expected, then the networking is right.

weak plinth Jun 22, 2020, 2:14 PM

#

so why is it only happening on the local side only?

#

it shouldnt

jade glacier Jun 22, 2020, 2:18 PM

#

Might want to post your code in the regular help channels, more people there to look at it.

weak plinth Jun 22, 2020, 2:18 PM

#

the health variable stays at 3 for the remote player

jade glacier Jun 22, 2020, 2:29 PM

if the RPC arrives, and you set the value in response to it... then something else is fighting with your sync.

@viscid tree , the game version (and PUN version) value(s) will separate players into so called "virtual apps". In other words: We don't match players of different Game Versions to avoid incompatibilities.

In PUN 1.9 the PhotonNetwork values for countOfPlayersInRooms and countOfPlayers are incorrect.
If you are relying on these values, you can fix them...

my problem from yesterday still stands, this line of code changes the currenthealth variable of another player. But the code doesn't change the variable for the remote player, only for the local. The rpc is working properly so what am i missing?

Colliding player isn't being sent as part of that rpc. Too many unknowns there to say.

Hello, I'm new to unity and currently am making an online trivia game and I need help in the networking side.
I tried many things I found on the internet and some worked but I couldn't add a timeout to the connection - would terminate and 2 seconds and freeze the screen.
And some do have a timeout without freezing but I cant exit the callback or setActive GameObjects if it fails connecting(The code terminates without any errors).
Anyone got a client that can has a custom timeout without freezing and I can call setActive with it terminating or can help me?

In the image you can see my scene and I want to show the Connecting To Server text and the loading animation until a connection error occurs and then hide the connecting and show the error with both of the buttons, how can i achieve this?

rugged parrot Jun 23, 2020, 10:06 PM

I'm having this issue with a project I've got. I have my game working fine with different people joining. But sometimes, there aren't enough people. So I wanted to get a few AI Agents in the mix.
I've got that part done. Where I'm having a problem is, my system is setup so that the scoreboard and the UI reflects kills and scores to the player. However, none of my bots are being registered as players since they're being instantiated in different levels.
My question here is that is it possible for me to add the bots as players in PhotonNetwork.playerlist?
So the system could work seamlessly.

marsh bison Jun 24, 2020, 2:55 AM

#

@rugged parrot Could you make another list, maybe "AgentList" or "RanksList" that combines the PhotonNetwork.playerlist and the botList? That seems much easier than trying to fool Photon into thinking that the bots are players.

rugged parrot Jun 24, 2020, 2:56 AM

#

I already have an agent list.

#

The problem is that when I do some tasks, say updating the scoreboard, it utilizes the custom properties laid out by photon for it's players.

#

A lot of those logics for different systems are linked that way to photon. So for that reason, for me at least, fooling photon seems easier 😓

#

If I could apply the custom properties of the players to the bots, that'll help as well

#

If not converting them into PhotonPlayers

marsh bison Jun 24, 2020, 2:59 AM

#

If you can read properties from bots and players, it seems like it would be easier to "get" information from PhotonNetwork.playerList than it would be to "set" information. If Photon does not expect people to do stuff like this, I would expect it to be extremely hard. What properties do you need?

rugged parrot Jun 24, 2020, 3:03 AM

#

I'm using player kills, death, score, teams and weapon. That's for the most part.

#

Also, I'm assuming C#'s HashTable class and Photon's HashTable classes are different, right?

#

Cuz I've used Photon's Hashtable and created the systems. So it'd be a pain to create another one for bots since it's deeply intertwined. So I was wondering if photon allowed us to create photonplayers and add it to the list.

marsh bison Jun 24, 2020, 4:31 AM

#

@rugged parrot I'm sorry. I cannot be of any more help to you.

rugged parrot Jun 24, 2020, 4:41 AM

Oh no. You've by far suggested and helped me the most out of all. Thanks for that @marsh bison.

marsh bison Jun 24, 2020, 4:41 AM

#

I'm glad I could help. I try to help the previous person before asking my own question.

#

Why might Photon destroy a gameObject without a destroy? Some [PunRPC] functions of mine that are called in the script governing player movement destroy the player. Calls to the below function often lead to the player being destroyed, but it is annoyingly fickle. I am trying to add a dash ability to my game, which temporarily freezes the player in the air until they choose a direction and release the mouse. I figured constraints would be the way to achieve this.

[PunRPC]
    private void SetRigidbodyConstraints(bool x, bool y, bool r)
    {
        if (x && y && r)
        {
            rigidbody2d.constraints = RigidbodyConstraints2D.FreezeAll;
        }
        else if (!x && !y && !r)
        {
            rigidbody2d.constraints = RigidbodyConstraints2D.None;
        }
        else if (x && y && !r)
        {
            rigidbody2d.constraints = RigidbodyConstraints2D.FreezePosition;
        }
        else if (x)
        {
            rigidbody2d.constraints = RigidbodyConstraints2D.FreezePositionX;
        }else if (y)
        {
            rigidbody2d.constraints = RigidbodyConstraints2D.FreezePositionY;
        }
        else if (r && !x && !y)
        {
            rigidbody2d.constraints = RigidbodyConstraints2D.FreezeRotation;
        }
    }```

#

I don't know exactly where the source of the bug is, but this function is part of the problem; deleting the calls to this function allows my program to otherwise work (just without the constraints being set).

drifting ridge Jun 24, 2020, 8:03 AM

#

Anyone knows the equivalent of OnPhotonPlayerActivityChanged in Photon Pun 2? I can't seem to find it in the docs. That seem to be in Pun v1

stiff ridge Jun 24, 2020, 8:21 AM

#

@drifting ridge, there is a callback when a player leaves or joins rooms. Those are used in PUN 2.

#

The player in question is passed to that method and you can check player.IsInactive.

#

We are about to release an update which adds Player.HasRejoined, which makes it more clear what is going on.

#

@marsh bison, you did not get any errors logged on the console / player log? That should usually point out the line of code that fails.

drifting ridge Jun 24, 2020, 8:32 AM

#

@stiff ridge ok thanks. Any estimate on when it will be released?

When a player disconnects, is there a way to see the ttl countdown of that player so that I know the time remaining for the player to join back into the game?

Am I right to say when the ttl timer is over, the player can no longer rejoin the game?

Does rejoining actually take into account of the room Is Open and Is Visible properties?

stiff ridge Jun 24, 2020, 8:36 AM

#

No, there is no way to see the individual ttl countdown per player. There is just another callback, when it's over, so you can only estimate the timing.
When the ttl is over, yes, the player can not rejoin the game. If the game is open and visible, the spot is free and this user or another could get matched into the room.
Rejoining works even if the room is closed and invisible. Technically, the player is keeping the spot in the room but is just inactive (not getting any current messages).

drifting ridge Jun 24, 2020, 8:41 AM

#

There is just another callback, when it's over, so you can only estimate the timing.
@stiff ridge
What is the this callback?
And thanks I understand how rejoining works better now.

#

Also CleanupCacheOnLeave happens after the ttl timer is over, correct?

stiff ridge Jun 24, 2020, 9:03 AM

#

Any estimate on when it will be released?
I hope today. Not entirely sure, as there's always one more feature we want in 🙂

#

The callback is actually a set of two: OnPlayerLeftRoom and OnPlayerEnteredRoom (part of InRoomCallbacks)

#

Yes, the CleanupCacheOnLeave refers to the server's Event Cache. It's the mechanism which we use to keep instantiate (and other events) in the server for late joiners and re-joiners.
This is cleaned up when a player is gone for good.

drifting ridge Jun 24, 2020, 9:20 AM

#

I see. New feature are always nice 🤩
Ok I understand. Thank you for explaining as this clears up a lot of confusion for me.
One last question, when I use LeaveRoom(), this makes the player be gone for good, correct? Meaning the ttl is no longer valid for the player and cannot rejoin?
@stiff ridge

stiff ridge Jun 24, 2020, 10:20 AM

#

@drifting ridge, LeaveRoom has an optional bool parameter "becomeInactive". It defaults to true but you can set it to false to leave a room skipping the ttl.

#

We meant this to be for turnbased games and async games, so if you'd enable a playerTTL, we assume you want to use it.

drifting ridge Jun 24, 2020, 12:25 PM

@stiff ridge Ok thank you!

@spring crane this is the debug message that appears https://cdn.discordapp.com/attachments/497874116246896640/725084054541828177/unknown.png

marsh bison Jun 24, 2020, 2:01 PM

#

@stiff ridge Sadly, I do not get an error message. The player is simply destroyed, and a bit later is destroyed on other windows of the game. The only time that I use a destroy in my code is with bullets getting destroyed when they hit something (or get replaced by a newer bullet), and that does not seem to have anything to do with the dash ability or the SetRigidbodyConstraints function. Is there anything that can lead to Photon deleting a gameobject? Is there a better way to temporarily freeze a rigidbody2D in place?

jade glacier Jun 24, 2020, 2:19 PM

#

Nothing in the code posted should lead to a destroy, so I would stick a debug in front of every Destroy() call in your code and check the trace on where the destroy action is coming from.

#

Are you sure it is being deleted? And that your code isn't teleporting it way off screen?

marsh bison Jun 24, 2020, 4:24 PM

#

@jade glacier It is being deleted. The camera is a child of the player, and the camera stops showing the scene (no cameras in scene), and in the Hierarchy the player disappears.

jade glacier Jun 24, 2020, 4:25 PM

#

Yeah, then track down every .Destroy() call and see what is causing it in the trace

marsh bison Jun 24, 2020, 4:28 PM

#

@jade glacier The only time I use destroy is when destroying bullets, which does not seem to have anything to do with this, and it checks that the tag is "Bullet", which for the player it is not.

jade glacier Jun 24, 2020, 4:29 PM

#

Something has to be destroying it somewhere, if it is getting destroyed. I would put a log before every call to Destroy in the entire solution, rather than spending too much time trying to guess.

#

Nothing in the code you posted is doing that, so it is outside of anyone's visibility here.

marsh bison Jun 24, 2020, 6:10 PM

#

@jade glacier Are there any event handlers or other places where PunRPC functions cannot be called?

jade glacier Jun 24, 2020, 6:11 PM

#

not sure what you mean by "places"

#

I actually don't know the limitations of RPC, I never use them. But I would expect they need to exist on the root with the PV.

#

It should be in the docs about RPCs where they need to go.

marsh bison Jun 24, 2020, 6:18 PM

#

@jade glacier I think that this sort of thing would happen if the player disconnected. What might cause the player to disconnect?

jade glacier Jun 24, 2020, 6:18 PM

#

You should be able to get log messages about disconnects, are you seeing those?

#

Assuming you have turned up the message level in photon settings to show all information in the log

marsh bison Jun 24, 2020, 6:22 PM

#

PUN logging FULL ? Or Network Logging ?

jade glacier Jun 24, 2020, 6:27 PM

#

Both sure, whatever

#

you just want lots of info

marsh bison Jun 24, 2020, 6:38 PM

#

@jade glacier Does SocketUdp.Disconnect() mean that the connection failed? If so, then the network is failing when I try to call the [PunRPC] functions related to the dash. Why would they cause it to disconnect?

jade glacier Jun 24, 2020, 6:39 PM

#

Not sure, but yeah - I would think a disconnect message means you are sending something it isn't happy about. What are you sending in that RPC?

icy otter Jun 24, 2020, 6:40 PM

I know this is broad, but what is the best way to do p2p? I want a vr thief simulator, where one person is a thief and the other person has to catch them before they steal everything. Im thinking using photon bolt, but I'm not sure on how it works or setup. Does anyone know?

Ah ok, thank you! I'll give this a watch later

marsh bison Jun 24, 2020, 6:48 PM

#

@jade glacier In the hopes that fewer RPC functions would make it work better, I combined the dash stuff into one function, and it actually seemed to make the program disconnect less often. The code that moves the player due to the dash is in Update. Should I try to cut down on the number of [PunRPC] calls I use? It still occasionally disconnects, but less often.

[PunRPC]
    private void FreezeDash(bool b)
    {
        if (b)
        {
            rigidbody2d.constraints = RigidbodyConstraints2D.FreezeAll;
            weaponObjects.transform.GetChild(useWChoices.IndexOf(usingWeapon)).gameObject.SetActive(false);
            if (Handy.GetChildWithName(this.gameObject, "DashArrow") != null)
            {
                Handy.GetChildWithName(this.gameObject, "DashArrow").SetActive(true);
            }
        }
        else
        {
            rigidbody2d.constraints = RigidbodyConstraints2D.FreezeRotation;
            weaponObjects.transform.GetChild(useWChoices.IndexOf(usingWeapon)).gameObject.SetActive(true);
            if (Handy.GetChildWithName(this.gameObject, "DashArrow") != null)
            {
                Handy.GetChildWithName(this.gameObject, "DashArrow").SetActive(false);
            }
        }
    }```

jade glacier Jun 24, 2020, 6:48 PM

#

too much for me to read in this chat window. But if you are only sending a bool that shouldn't be causing any problems. Unless you are somehow sending that 3000 times per tick.

marsh bison Jun 24, 2020, 6:54 PM

#

@jade glacier I do not think that it is being called that often... This is the event handler:csharp void OnGUI() { if(PV.IsMine){ startDash(Event.current); } }
This is the function where the [PunRPC] is called:

private void startDash(Event currentEvent){
        Vector2 mousePos = new Vector2();
        Vector2 point = new Vector2();

        // compute where the mouse is in world space
        mousePos.x = currentEvent.mousePosition.x;
        mousePos.y = cam.pixelHeight - currentEvent.mousePosition.y;
        Vector3 v3 = new Vector3(mousePos.x, mousePos.y, 0.0f);
        point = cam.ScreenToWorldPoint(v3);
        if (Input.GetMouseButton(1) && dashable && initiatePauseOnce)
        {
            PV.RPC("FreezeDash", RpcTarget.All, true);
            initiatePauseOnce = false;
        }
        else if(Input.GetMouseButtonUp(1) && dashable){
            initiatePauseOnce = true;
            PV.RPC("FreezeDash", RpcTarget.All, false);
            HandyPun.allLog("Up Mouse Dash");
            dashMousePos = point;
            Vector2 tpv2 = transform.position;
            Vector2 diffv2 = dashMousePos-tpv2;
            diffv2 *= dashLength/diffv2.magnitude;
            dashMousePos = diffv2 + tpv2;
            inDash = true;
            dashable = false;    
        }
    }```
How often would it be called? I would think only once when right click down, once when right click up.

icy otter Jun 24, 2020, 6:59 PM

#

@marsh bison by the way, do u think my game sounds fun to play?

marsh bison Jun 24, 2020, 7:00 PM

#

@icy otter Yeah, it really does. It would be a great party game. Add some funny physics interactions and ragdolls, and you have a viral game.

icy otter Jun 24, 2020, 7:00 PM

#

Haha thanks!

marsh bison Jun 24, 2020, 7:39 PM

#

@jade glacier I think that I got it. I think I was calling too many PunRPC functions. Unfortunately, as I expand the game, I will only be adding more. It will be tricky to avoid calling so many that it disconnects.

spring crane Jun 24, 2020, 7:44 PM

#

@marsh bison What are you trying to do with that OnGUI thing? That seems bad

marsh bison Jun 24, 2020, 7:45 PM

#

I wanted a right click down to start a dash. I thought OnGUI was how to do that.

spring crane Jun 24, 2020, 7:46 PM

#

I would really look into how often that is firing, and it most likely isn't the way to do this

#

Use Update with an Input condition or input events of the new input system

#

Afaik OnGUI is called whenever pretty much any potential interaction with the old immediate mode UI system can happen, which could potentially include just the act of holding some button down

marsh bison Jun 24, 2020, 7:50 PM

#

Ok, I can switch to update. You will notice that I have a bool initiatePauseOnce that is sort of a lazy way to stop it from calling too often.

#

How can I get Event in Update?

spring crane Jun 24, 2020, 7:51 PM

#

Oh I misread as startDash being the RPC

#

In that case it's fine, though a bit unconventional to use OnGUI for that

#

I really don't think you should be hitting RPC send limits that easily if you are using common sense

#

Maybe mobile devices might struggle a bit

marsh bison Jun 24, 2020, 8:01 PM

#

I had a few other unnecessary RPC ‘s that we’re called every frame that I didn’t really need that I got rid of.

jade glacier Jun 24, 2020, 10:35 PM

#

How many where you calling? It would take quite a few to force a kick.

marsh bison Jun 25, 2020, 2:46 AM

#

@jade glacier I made a singleton with a PhotonView that allows me to get debug.Logs from all players. There were two calls to that, three [PunRPC] calls that set an int, and I had a PhotonNetwork.Destroy(bullet) inside of a [PunRPC] function.

#

Might it have been that last thing?

jade glacier Jun 25, 2020, 3:53 AM

#

I hope you arent making bullets networked objects. No idea of that is part of the problem, but it's a terrible idea.

drifting ridge Jun 25, 2020, 3:59 AM

In pun2, when I'm the only player left in the room (hence the host/master client) and I leave the room, why doesn't the OnPlayerLeftRoom callback is run?

#

@drifting ridge, this is what the docs say for OnPlayerLeftRoom:

/// Called when a remote player left the room or became inactive. Check otherPlayer.IsInactive.

Locally, there is the call of IMatchmakingCallbacks.OnLeftRoom

gleaming prawn Jun 25, 2020, 9:25 AM

#

If you are trying to create an online multiplayer game, first thing to do is START with multiplayer from the first moment.

#

Second thing: do Not start with "a large online multiplayer" game

#

you will not finish it.

#

Start with something simpler...

THEN, answers:

check PUN2 (photon), Mirror, and other options for multiplayer SDKs

Should I not use UNET?

gleaming prawn Jun 25, 2020, 9:27 AM

#

make sure to start with something very simple (if you have no experience with online multiplayer development, take this as professional advice)

#

Should I not use UNET?
UNet has been (abandoned) deprecated for a while already

#

Unity has absolutely no proper multiplayer built-in.

#

They are starting over for the 3rd time, and it's not nearly complete.

merry gazelle Jun 25, 2020, 9:28 AM

#

Ok thanks for the help!

gleaming prawn Jun 25, 2020, 9:28 AM

#

Mirror is the open source branch of old UNet (with improvements)

#

So UNet tutorials more or less still work (should) for it

#

For beginners, the usual choices are PUN2 (photon), Mirror, Photon Bolt.

I dont know how to create a team

#

also for some reason my health is updating in the code like it prints that that the health slider is going down in value but visually it doesn't go down

jade glacier Jun 25, 2020, 1:09 PM

#

You either aren't telling the UI to change, or you have other code fighting with the networking code locally.

empty quiver Jun 25, 2020, 1:09 PM

#

would u use this to define a team?

📎 unknown.png

#

Im 100% its not something to do with the networking

#

its works on a another scene that I have made that doesnt use the same player

#

I have this in the update function

📎 unknown.png

jade glacier Jun 25, 2020, 1:11 PM

#

and health is being changed ONLY by the incoming RPCs for objects that you don't own?

#

My guess is you aren't IsMine testing your local player code, and it is running on un-owned players as well.

empty quiver Jun 25, 2020, 1:13 PM

#

for the most part yes but I made a coroutine to test if the health slider decreased when the health value decreased

#

but even with 1 person in the scene the health bar never changes visually

jade glacier Jun 25, 2020, 1:14 PM

#

Not sure glancing at the docs how you join a team @empty quiver

empty quiver Jun 25, 2020, 1:15 PM

#

it changes in the code but not for the ui

📎 unknown.png

#

📎 unknown.png

#

this is what im using to test the health

📎 unknown.png

jade glacier Jun 25, 2020, 1:18 PM

#

Nothing else is trying to adjust that slider anywhere?

empty quiver Jun 25, 2020, 1:18 PM

#

only here but this is only called in the start function

📎 unknown.png

jade glacier Jun 25, 2020, 1:19 PM

#

Dunno, something we aren't seeing is acting on that.

#

https://doc-api.photonengine.com/en/pun/v2/class_photon_1_1_pun_1_1_utility_scripts_1_1_photon_team_extensions.html

Docs that seem to touch on the JoinTeam() part of teams.

#

Side note, I would rethink that coroutine. Better to have your Canvas have its own tick that generates callbacks if you are going that route.

empty quiver Jun 25, 2020, 1:24 PM

#

Its just for testing

#

so the teams are predefined and you get players to join teams by changing a value of a team to true or false

jade glacier Jun 25, 2020, 1:26 PM

#

For testing, just stick it in an Update then, no point adding complexity to your basic tests

#

Not sure how teams work with the built in thing, you know more than me at this point on that topic.

#

I don't see your coroutine calling SetHealth btw

#

Should this not be calling the SetHealth() method?

📎 unknown.png

empty quiver Jun 25, 2020, 1:34 PM

#

its in the update method also yes that works a lot better

#

it doesnt update as fast now which is good because it doesnt need to cheers

#

this is what my update method looks like

📎 unknown.png

jade glacier Jun 25, 2020, 1:45 PM

#

You are starting a coroutine in Update? That isn't doing what I think you think it is doing though.

empty quiver Jun 25, 2020, 1:46 PM

#

I think I figured out what the issue is I think its changing the value of the prefab and not the game object in the scene

jade glacier Jun 25, 2020, 1:46 PM

#

That would do it.

empty quiver Jun 25, 2020, 1:50 PM

#

I cant seem to reference the game object in the scene it keeps using the prefab

#

that did it just found the object with the tag health and got the slider component from it, thanks for the help

jade glacier Jun 25, 2020, 1:56 PM

#

You will have to set it at runtime most likely

#

There is no reference until you run and spawn the player.

#

So in your players Start() you will likely want an IsMine test, and assign it from there.

#

That coroutine still needs to go, you will be spawning like 60 of those things a second.

Hey guys, can someone teach me networking in unity because i want to make a multiplayer game and i don't know how to do it without using UNet(I know just a liitle bit of UNet, i heard they're gonna remove it and i want something stable for my game) Game Topic: Top Down Shooter.

jade glacier Jun 25, 2020, 2:21 PM

#

No one will likely do that that for you, anyone who knows this stuff is way too busy working. You will need to do tutorials for libraries like Mirror, Photon Pun2, and Photon Bolt - then ask questions.

i used the oculus integratiion kit, how can i make it so my movmement is syncronised with photon bolt? do i just need to derive it from the photon thing instead of monobehavior?

drifting ridge Jun 25, 2020, 2:48 PM

#

@stiff ridge weird I didn't receive any notification and waited the whole day... But that works! Sorry I missed the docs I remember looking through it a couple of times. There were times I happened to be scrolling through the docs of Pun V1 🤦‍♂️

jade glacier Jun 25, 2020, 4:08 PM

#

Will check into that, but pretty sure we didn't touch that. Might be some other race condition in play.

#

Can you paste the actual log error?

#

And where are you calling that from in your code?

#

That was changed a while back if I think it is what it looks like. If it was working before, you may have been calling it at a time before the object had completed initialization.

#

We removed some code that did a brute force scene lookup that was expensive, if the basic find failed.

#

But it should only fail if users are trying to access the ID before the object has been registered.

#

@weak plinth

#

You can uncomment that code in PhotonNetworkPart.cs to see if it restores that to working. If so, I would be interested to know where in your callbacks you are making that call from.

📎 unknown.png

jade glacier Jun 25, 2020, 5:40 PM

#

We may just enable that block of code again - but it is a bit expensive. I think you are making use of the find before the object actually has initialized.

tight kestrel Jun 25, 2020, 7:24 PM

If anyone has any ideas what can cause this strange error, It would be much appreciated.
Here is my code which sends a put request with data:

string json = JsonUtility.ToJson(report);
UnityWebRequest req = UnityWebRequest.Put(StaticVars.BaseURL + "/user/scores/score", json);
req.SetRequestHeader("Content-Type", "application/json");
yield return req.SendWebRequest();

Here is what the webserver receives in the correct case (almost every user):
REST Request - [HTTP METHOD:PUT] [PATH INFO:/user/scores/score] [REQUEST PARAMETERS:{}] [REQUEST BODY:{"userId":xxxxxxxx,"packId":38,"userName":"xxxxxxxx","totalTime":43}] [REMOTE ADDRESS:xxx.xxx.xxx.xxx]
And here is what the webserver receives from one specific user (OS Catalina version 10.15.4):
REST Request - [HTTP METHOD:PUT] [PATH INFO:/user/scores/score] [REQUEST PARAMETERS:{}] [REQUEST BODY:PUT /user/scores/score HTTP/1.1Host: xxx.xxx.xxx.xxxUser-Agent: UnityPlayer/2019.4.0fl (UnityWebRequest/1.0, lubcurl1/7.] [REMOTE ADDRESS:xxx.xxx.xxx.xxx]

#

One user's request body is somehow the request URL and the request headers concatenated, which is so weird and I have no clue why

slim ridge Jun 25, 2020, 7:48 PM

#

try using UnityWebRequest.Put with a byte array instead of string and see how it behaves

tight kestrel Jun 25, 2020, 7:50 PM

#

I originally had it with a byte array and changed it to string the first time I got this error. It's the same problem 😦

slim ridge Jun 25, 2020, 7:52 PM

#

do you get the same result with POST?

#

catalina is terrible for games anyways and it broke quite a few

tight kestrel Jun 25, 2020, 7:54 PM

#

I will try post but it's difficult because I don't own the catalina machine so I am using a legit player of the game for testing lmao

#

also the game is in production already xD

slim ridge Jun 25, 2020, 7:57 PM

#

oof

tight kestrel Jun 25, 2020, 7:58 PM

#

@slim ridge When I use post, it looks like the string gets urlencoded for some reason

slim ridge Jun 25, 2020, 7:59 PM

#

well since it's in production the first thing i'd do is look for this specific case in your server code and manually parse the body :S

#

then work on getting a catalina machine

tight kestrel Jun 25, 2020, 8:01 PM

#

I guess I really just need a catalina machine

#

I don't even know if post would work on one, and I'm using spring which automatically parses json into the object, so it will be very annoying to do any sort of manual parsing

#

UPDATE: It might be some firewall setting on the person's router, because the error message shows the data that got sent in the packet was correct, but it isn't received properly on the webserver. The only way that can happen is something in the middle changing the data

slim ridge Jun 25, 2020, 8:04 PM

#

it's probably some system call that's not acting the way unity expects

#

or that

#

saved by user error 😄

Ight, I need some help with Mirror, so when i use my host button i start the host and my player spawns and everything is good, but if i exit and host again i spawn 2 players, how should i fix this? I use the basic code from dappers tutorial but i then tried to change it up a bit, (just spawning a player instead of an empty object), but when i end the host and host again it spawns double characters,
EndHost function:
public void EndHost()
{
networkManager.StopHost();
landingPagePanel.SetActive(true);
OtherUI.SetActive(false);
}

wispy thorn Jun 26, 2020, 11:26 AM

Need some professional advice. Am I goin about this all wrong? So I want to design a real time Multiplayer game and would like it to scale pretty well. What I'm doing now is making a game in Unity that doesn't rely on Monobehaviours. Monobehaviours will pretty much be only used for visuals but not core game mechanics. The big hurdle in this case was to utilize System.Numeris.Vector2 and not Unity Engine.Vector2 (and ofcourse writing custom physics to achieve the behaviour we want). The dream is that when making the server we can use the exact same code the client is using on the server to recreate the game on it's end to ensure the players are in sync and not cheating.

Am I going about this all wrong? I know there are systems out there that will run a version of the game on a unity server, but unless im wrong they seem to be on very efficient.

gleaming prawn Jun 26, 2020, 11:52 AM

#

@wispy thorn that's not the wrong direction, no. That's exactly what we do with photon quantum.

#

It's just a ton of work (own physics, own navigation, so forth)

#

So doing this for a single game is overkill

cursive flame Jun 26, 2020, 12:08 PM

#

I am using photon for a small multiplayer game and want to have a timer in the game, that is synchronized for all players. How can I do something like that? Should I choose one player that runs an extra script for that or is there any way the server can manage that?

empty quiver Jun 26, 2020, 12:12 PM

#

Id have it inside ur player script and use an RPC function to broadcast it to everyone depends how the timer is gonna act tho

cursive flame Jun 26, 2020, 12:13 PM

#

I want to have a day and night cycle, and therefore I have a clock. And obviously that needs to be synchronized

empty quiver Jun 26, 2020, 12:18 PM

#

I think u could do that with an RPC function

#

Id use a coroutine to keep track of the time and have that method in a RPC function that broadcasts to every player in the lobby and anyone who joins

#

PV.RPC("RPC Method", RpcTarget.AllBufferedViaServer); I think this is what u would do to get it to work with every player in the scene and who ever joins

jade glacier Jun 26, 2020, 12:23 PM

#

Time is a very lazy thing, so you could just send an RPC when new players join to get them up to speed (use OnPlayerEnteredRoom() on the Master), and send out vary infrequenct RPCs of the time.

empty quiver Jun 26, 2020, 12:24 PM

#

That would be a better method wouldn't take as much resources

jade glacier Jun 26, 2020, 12:25 PM

#

I would strongly advise against using coroutines like that - they are a debugging nightmare and just don't gain you much. They still fire on the main thread. They just get deferred to an Update timing that is after the normal Update().

#

If you have a main game loop in an update, have that check Time or deltaTime and send based on progress of one of those values.

cursive flame Jun 26, 2020, 12:28 PM

#

well I only need to update the time when a player joins. Each player has the clock methode themself

jade glacier Jun 26, 2020, 12:29 PM

#

They won't fall out of sync very quickly, so you probably could just sync once. But if you are concerned you could just send and update every second or something.

cursive flame Jun 26, 2020, 12:29 PM

#

they wont get out of sync

jade glacier Jun 26, 2020, 12:29 PM

#

Unless the time of day affects the game simulation, then you might want to embed it into your sent messages.

#

But it sounded cosmetic.

empty quiver Jun 26, 2020, 12:32 PM

#

as long as the rpc function is sent at the same time to everyone I think it will be fine

jade glacier Jun 26, 2020, 12:34 PM

#

It will not be tick perfect, for that you would need your sim to be tick based and serialize/deserialize/apply the time on tick. If it is not part of your simulation or anything determnistic in nature.... just an RPC to the target joining player when they enter will do fine.

#

clients will all be within a few hundred ms of agreement

cursive flame Jun 26, 2020, 12:38 PM

#

well I am using Time.deltaTime

empty quiver Jun 26, 2020, 1:13 PM

#

I think that would work fine 😄

#

got it: re-assign it to Socket.LocalEndPoint after calling Socket.Bind 👍

high girder Jun 26, 2020, 3:35 PM

#

Anyone know why Socket.ConnectAsync has odd behaviour. Does it always call the completed event, even if it completed synchronously?

slim ridge Jun 26, 2020, 3:40 PM

#

yes

#

are you looking for Task.IsCompletedSuccessfully ?

high girder Jun 26, 2020, 3:47 PM

#

had a funny line

#

its okay

#

but it still weird

#

the server is sat waiting to accept connections

#

the server is a .net core app

#

then in unity I have a Connect button

#

it says it completed successfully, but the server doesnt show a connection attempt

#

only when you stop playing the unity, does the server then say a connection was attempted

slim ridge Jun 26, 2020, 3:50 PM

#

sounds one side is stuck at a blocking operation

high girder Jun 26, 2020, 3:51 PM

#

the thing is. i know the server works, as i had a net core client connect and send / receive data

#

the only difference really is that unity is running mono

slim ridge Jun 26, 2020, 3:52 PM

#

i bet if you look really closely you'll find more difference

#

could be as simple as your IP changed since then

high girder Jun 26, 2020, 3:52 PM

#

loopback

#

like i said. the server shows the connection attempt, but only when you press the play icon in unity to stop playing.

#

ive probable messed up somewhere

#

will keep digging

what would be the best way of going about running a dedicated server thats always active whether players are in it or not

#

from what im seeing photon and other programs only have lobbies that end after the player leaves

icy otter Jun 27, 2020, 9:26 AM

#

You would need to have a bunch of servers set up and running all the time i beleive

#

Photon bolt does p2p where on person acts as the server and a client

#

But i cant get my head around it

for some reason when a player attacks another player the value of the slider on the player they hit doesnt decrease in value even though there health goes down but when the client decreases there own health the health bars value does decrease

or should it be with ip?

#

someone pls?

jade glacier Jun 27, 2020, 2:47 PM

No one is a "server" with Pun, the relay is the server. All players are clients to that Relay Server.

@tropic creek Just follow a tutorial, it will show you how to connect via matchmaking
The photon cloud and matchmaking will connect you will your friend
All your data passes through the cloud and you can have 20 connections at a time for free
