[inland sand]

But I won't give up

[jovial pike]

why doesn't it sync?

[inland sand]

Did you add photon transform view component?

[jovial pike]

ouh...

for both players?

[inland sand]

for the ball

[jovial pike]

ok

[inland sand]

And yes both player @jovial pike

[jovial pike]

do i have to change something in the script?

[inland sand]

no ig

[jovial pike]

thx

[inland sand]

You can follow along this tutorial

[jovial pike]

😄

thank you

[jovial pike]

if (!this.photonView.IsMine)
            {
                if (m_UseLocal)

                {
                    tr.localPosition = Vector3.MoveTowards(tr.localPosition, this.m_NetworkPosition, this.m_Distance * (1.0f / PhotonNetwork.SerializationRate));
                    tr.localRotation = Quaternion.RotateTowards(tr.localRotation, this.m_NetworkRotation, this.m_Angle * (1.0f / PhotonNetwork.SerializationRate));
                }
                else
                {
                    tr.position = Vector3.MoveTowards(tr.position, this.m_NetworkPosition, this.m_Distance * (1.0f / PhotonNetwork.SerializationRate));
                    tr.rotation = Quaternion.RotateTowards(tr.rotation, this.m_NetworkRotation, this.m_Angle * (1.0f / PhotonNetwork.SerializationRate));
                }
            }

i never opened this script

why is there an error?

[jovial pike]

maybe i have to use photonView.IsMine in my move script?

I will try it

if (pv.IsMine && ptv.photonView.IsMine)

can i use this?

        ptv = GetComponent<PhotonTransformView>();

ptv is my photontransformview

no it doesnt work

[inland sand]

Use if(!view.IsMine)
return;

[jovial pike]

ok

[inland sand]

You gotta add a photon view component

[jovial pike]

i have

[inland sand]

A photon transform view component

And animator view if you have any animator

Animation*

[jovial pike]

 void FixedUpdate()
    {
        if (pv.IsMine)
        {
            float horizontal = Input.GetAxis("Horizontal2");
            if (Input.GetKey(KeyCode.I))
            {
                RaycastHit2D hit = Physics2D.Raycast(gameObject.transform.position, Vector2.down, rayCheckDistance);
                if (hit.collider != null)
                {
                    rb.AddForce(Vector2.up * jump, ForceMode2D.Impulse);
                }
            }
            rb.velocity = new Vector3(horizontal * speed, rb.velocity.y, 0);

            Flip(horizontal);

            if (Input.GetKey(KeyCode.K))
            {
                gravityScale = 5;
            }
            else
            {
                gravityScale = 1;

            }
            rb.gravityScale = gravityScale;
        }
    }

 Rigidbody2D rb;
    PhotonView pv;
    PhotonTransformView ptv;

    void Start()
    {
        rb = GetComponent<Rigidbody2D>();
        pv = GetComponent<PhotonView>();
        ptv = GetComponent<PhotonTransformView>();
    }

[inland sand]

If using rigidbody, use photon rigidbody view

[jovial pike]

i have on in my prefab

but do i have to call it in the script?

[inland sand]

No

[jovial pike]

ok

[inland sand]

You only need photon view

[jovial pike]

ouh ok

then i have all

i think

[inland sand]

Then what's the error?

[jovial pike]

i really dont know

i can show my components

[inland sand]

then it should be working right?

[jovial pike]

i have the script and the components

[inland sand]

Build and test it out

[jovial pike]

ok

[inland sand]

Or wait

Nvm

[jovial pike]

now it doesnt even start

[inland sand]

Eh

Why?

[jovial pike]

...

because of this

[inland sand]

Are you following along with the tutorial? @jovial pike

[jovial pike]

yes

it worked but i dont know what i changed

[jovial pike]

that was the problem

[inland sand]

ya why are you using photonviewtransform.ismine

You just need photonview.ismine

[jovial pike]

i tried it

ok

[jovial pike]

what do i have to do to fix it?

[inland sand]

it's still having that error?

[jovial pike]

yes

again

[inland sand]

Umm, remove photon transform view

And andd transform view classic

[jovial pike]

ok

[inland sand]

https://docs.unity3d.com/Manual/NullReferenceException.html

[jovial pike]

ouhh

i know why

i also put one on the ball

[inland sand]

ig you should re do everything and follow along with the tutorial because there are many things i.e wrong In your code

[jovial pike]

but can i use isMine on the ball?

[inland sand]

you want the ball to be controlled by player?

[jovial pike]

nope

just a rigidbody

[inland sand]

ismine is used when you don't want your player to move others' player

[jovial pike]

ok

then i remove the transform on the ball

[inland sand]

its stated in the tutorial

[inland sand]

No dont

[jovial pike]

but you cant controll the ball

[inland sand]

Transform view syncs the transform to all the clients on server

[jovial pike]

ouhhh

ok

[inland sand]

bruh, watch the tutorial I sent you abovr

[jovial pike]

do the camera need a photon transform?

ok

[inland sand]

Ya if its a moving camera

[jovial pike]

ok

thx

it still doesnt work 😦

[jovial pike]

I did everything that he did in the video

if (pv.IsMine)
        {
            float horizontal = Input.GetAxis("Horizontal");

            if (Input.GetKey(KeyCode.W))
            {
                RaycastHit2D hit = Physics2D.Raycast(gameObject.transform.position, Vector2.down, rayCheckDistance);
                if (hit.collider != null)
                {
                    rb.AddForce(Vector2.up * jump, ForceMode2D.Impulse);
                }
            }

Is anything missing?

[inland sand]

you doing everything in playmode?

[jovial pike]

yes

[cedar cloak]

Photon PUN: I need to sync the player that is just entered in the room, so inside the OnPlayerEnteredRoom how can I call an RPC specifically aimed to that new player?

[jovial pike]

i think my problem is that i have two player objects and not one.

[inland sand]

Bro, ig you need to instantiate player when joining

Not with scene

[jovial pike]

ouh

in the ConnectToServer Script?

OrCreateRoom Script?

public override void OnJoinedRoom()
    {
        PhotonNetwork.LoadLevel("SampleScene");
        PhotonNetwork.Instantiate("Player", spawnLocationLeft.transform.position, Quaternion.identity, 0);
    }

like this?

[spring cargo]

Hello Everyone,
I was thinking if it's possible to control a standalone application using my mobile phone (offline - no internet)

Like I create a scene in Unity with a cube, make it a standalone app and then maybe change the color of that cube using my phone. My phone can have the same application. Just that everything should be offline. I want a way to communicate with the standalone application using my phone.

[icy thorn]

Are you ok with going via LAN? Bluetooth?

Are the cube app and phone on the same LAN?

Are they in different places geographically?

LAN networking doesnt require internet

But going to different houses or to a different coubtry does

It will require going over the internet, and there isnt much yiu can do about that

[spring cargo]

@icy thorn yes bluetooth/lan works. It would be in the same space. Just like how we have a controller for a PS4 system.

Could you help me with this?

[jovial pike]

can you help me with my photon problem?

I do not know what I'm doing wrong

[river meteor]

whats the problem

[jovial pike]

it doesnt sync

[river meteor]

show me your code for room creating/joining you can herte on dm

[jovial pike]

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using Photon.Pun;

public class CreateAndJoinRooms : MonoBehaviourPunCallbacks
{
    public InputField createInput;
    public InputField joinInput;

    public void CreateRoom()
    {
        PhotonNetwork.CreateRoom(createInput.text);
    }

    public void JoinRoom()
    {
        PhotonNetwork.CreateRoom(joinInput.text);
    }

    public override void OnJoinedRoom()
    {
        PhotonNetwork.LoadLevel("SampleScene");
    }
}

[jovial pike]

omg

i switched the join and create button

now it loads longer

but the second screen isnt loading at all

[jovial pike]

when pressing join

[river meteor]

why are you ccreating room in join room?

You should use PhotonNetwork.JoinRoom(joinInput.text)

[jovial pike]

I thought I changed it

sorry

[river meteor]

you also should have before it all ConnectToMaster function

sorryu

connectusingsettings

[jovial pike]

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Photon.Pun;
using UnityEngine.SceneManagement;

public class ConnectToServer : MonoBehaviourPunCallbacks
{
    void Start()
    {
        PhotonNetwork.ConnectUsingSettings();
    }

    public override void OnConnectedToMaster()
    {
        PhotonNetwork.JoinLobby();
    }

    public override void OnJoinedLobby()
    {
        SceneManager.LoadScene("Lobby");
    }
}

This Script is in my Loading Scene

[river meteor]

ah you are using lobby system, so I dont know how it is going

[jovial pike]

i really dont need a lobby

I thought it wouldnt work without a lobby

omg it works

its laggy but it works

[jovial pike]

THX

[river meteor]

so what was issue?

[jovial pike]

the Create in the joining method

but i really thought i have changed it

[jovial pike]

I have one short and last question :S

[river meteor]

yeah sure

[jovial pike]

it always spawns both player

i know why but i dont know how to fix it

[river meteor]

I think because you have already player placed in scene

[jovial pike]

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Photon.Pun;

public class LeftSpawnPoint : MonoBehaviour
{
    public GameObject spawnLocationLeft;

    void Awake()
    {
        spawnLocationLeft = GameObject.FindGameObjectWithTag("SpawnPointLeft");
    }

    void Start()
    {

        SpawnPlayer();
    } 

    private void SpawnPlayer()
    {
        PhotonNetwork.Instantiate("Player", spawnLocationLeft.transform.position, Quaternion.identity, 0);
    }
}

[jovial pike]

no i instantiate them

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Photon.Pun;

public class RightSpawnPoint : MonoBehaviour
{
    public GameObject spawnLocationRight;

    void Awake()
    {
        spawnLocationRight = GameObject.FindGameObjectWithTag("SpawnPointRight");
    }

    void Start()
    {

        SpawnPlayer();
    } 

    private void SpawnPlayer()
    {
        PhotonNetwork.Instantiate("Player2", spawnLocationRight.transform.position, Quaternion.identity, 0);
    }
}

[river meteor]

move you instantiate function to OnJoinRoom callback and it shouldbe ok

[jovial pike]

this i for the right spawner

[jovial pike]

thx

[river meteor]

and why you have two different prefabs for players?

[jovial pike]

because they have different movement scripts

i controll one with "w a s d" and the other with "i j k l"

[river meteor]

aaah okey okey

but I can give you some advice about that

[jovial pike]

really?

[river meteor]

you can also have only one prefab but two different movement scripts and apply for the same player but at start disable one.. then you can enable them determining if one of them is master client

depending on in if one of them is master client

I consider your game will always have max two players, right?

[jovial pike]

yes

[jovial pike]

thats a good idea

[river meteor]

I will do this in way I described but I dont say your solution is bad or something

treat it just like a tip 😄

[jovial pike]

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using Photon.Pun;

public class CreateAndJoinRooms : MonoBehaviourPunCallbacks
{
    public InputField createInput;
    public InputField joinInput;

    public GameObject spawnLocationLeft;
    public GameObject spawnLocationRight;

    public void Awake()
    {
        spawnLocationLeft = GameObject.FindGameObjectWithTag("SpawnPointLeft");
        spawnLocationRight = GameObject.FindGameObjectWithTag("SpawnPointRight");
    }
    public void CreateRoom()
    {
        PhotonNetwork.CreateRoom(createInput.text);
    }

    public void JoinRoom()
    {
        PhotonNetwork.JoinRoom(joinInput.text);
    }

    public override void OnJoinedRoom()
    {
        PhotonNetwork.LoadLevel("SampleScene");
        PhotonNetwork.Instantiate("Player", spawnLocationLeft.transform.position, Quaternion.identity, 0);
        PhotonNetwork.Instantiate("Player2", spawnLocationRight.transform.position, Quaternion.identity, 0);

    }
}

ouh wait

[river meteor]

yep but with this code it always will instantiate two players

no matter if second one has joined

[jovial pike]

and the other problem is that he cant find the spawnLocations

because its not the right scene

[river meteor]

and when second player will join the another two players will spawn

[jovial pike]

ouh

then i have to use your ideo

*idea

so i give my prefab player both scripts an when he spawns i will disable one of the scripts

[river meteor]

slove first of all problem with player spawning - give them temporary fixed locations in code

then workaround the spawnpoint system

[jovial pike]

ok thx 😄

[river meteor]

solution for you problem is just to move your code

        spawnLocationLeft = GameObject.FindGameObjectWithTag("SpawnPointLeft");
        spawnLocationRight = GameObject.FindGameObjectWithTag("SpawnPointRight");```

this into another place 😉

[jovial pike]

i removed that

i will use Vector3 (0,0,0)

[river meteor]

no, you can leave it

but think about where you can put it

[jovial pike]

ok

[river meteor]

you already say what is the solution for it

[river meteor]

.

[jovial pike]

ouh so i can use the spawnpoints

nice

ok i know what to do

thx

[river meteor]

remember, code is executed from top to the bottom

so

1. Load a scene
2. Load spawnpoints
3. Spawn the players

viola

[jovial pike]

i will set a bool variable on my spawn script. and i will set it in my CreateAndJoinRoom script to true.

can i do that

[river meteor]

you dosent have to

[jovial pike]

ouh ok

[river meteor]

look into your OnJoinRoom callback

OnJoinedRoom *

[jovial pike]

but the CreateAndJoinRoom is on another scene

is that a problem?

[river meteor]

nope

[jovial pike]

ouh nice

now i get it

[river meteor]

if you have DontDestroyOnLoad

it is not

[jovial pike]

after LoadLevel i can instantiate the spawnpoint and player

[river meteor]

in playable scene you can place fixed spawnpoints

after loading scene in OnJoinedRoom

You can get these spawnpoints with your code from Awake function

then

Instantiate players

you still didnt get it? 😄

[jovial pike]

i got it

a bit

[river meteor]

I know the easiest solutions are the hardest one to find

xD

[jovial pike]

xD

yes

[river meteor]

and I think it is the moment when you should stop coding, get a walk, comeback and work it around

😄

I do it everytime when my mind is blowing, but instead of getting a walk I am going to my proper job

[jovial pike]

when i'm sitting on something i work on it until it works

I've been trying to get my photon working all day

but i will make it

and thanks for you help

[jovial pike]

do you mean i can put spawn points in my lobby scene and use dontdestroyonload to keep it there when loading my game scene?

[river meteor]

no!

keep them in the correct playable scene

[jovial pike]

i have

i will try something

but my problem is i dont know how i can find the GameObject in my CreateRoom Script

i cant use this

[river meteor]

okey I will tell you what is the solution

yes you can

[jovial pike]

how

spawnLocationLeft = GameObject.FindGameObjectWithTag("SpawnPointLeft");
        spawnLocationRight = GameObject.FindGameObjectWithTag("SpawnPointRight");

[jovial pike]

thx

[river meteor]

    public override void OnJoinedRoom()
    {
        PhotonNetwork.LoadLevel("SampleScene"); // FIRST SWITCH SCENE
        spawnLocationLeft = GameObject.FindGameObjectWithTag("SpawnPointLeft"); // NOW WHEN WE ARE ON CORRECT SCENE WE CAN GET THE SPAWN POINTS
        spawnLocationRight = GameObject.FindGameObjectWithTag("SpawnPointRight");
        PhotonNetwork.Instantiate("Player", spawnLocationLeft.transform.position, Quaternion.identity, 0); // SPAWNPOINTS ARE NO MORE NULL REFERENCE SO WE CAN USE THEM
        PhotonNetwork.Instantiate("Player2", spawnLocationRight.transform.position, Quaternion.identity, 0);

    }```

[jovial pike]

you can do that???

wow

[river meteor]

I think so

but your script CreatAndJoinRooms must be DontDestroyOnLoad

[jovial pike]

ok

        DontDestroyOnLoad(gameObject);

in awake

[river meteor]

but this gameobject must be with createandjoinrooms

script

[jovial pike]

yes

he cant find the player

        PhotonNetwork.Instantiate("Player", spawnLocationLeft.transform.position, Quaternion.identity, 0);

this is the line 38

[jovial pike]

or maybe he isnt finding the Spawnpoint. i cant really tell

[river meteor]

hmm

okey so maybe this solution is not a right one xD

[jovial pike]

xD bruh

[river meteor]

okey just put positions in code

[jovial pike]

oki

[river meteor]

I will take a look later how I have it solved with spawnpoints

[jovial pike]

kk

thx

[ornate zinc]

you can just Debug.Log both and see if it finds it or not? If you debug log the spawnLocationLeft and it returns null, that might be your issue, otherwise its the Player object

[jovial pike]

thx but i found a solution

[ornate zinc]

Just dont hesitate to let others know 😄

[jovial pike]

can you help me with another problem?

[jovial pike]

i just used Vector3(x, y, z) instead of setting a spawnpoint with references

[jovial pike]

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using Photon.Pun;

public class CreateAndJoinRooms : MonoBehaviourPunCallbacks
{
    public InputField createInput;
    public InputField joinInput;

    private GameObject Player;

    public void Awake()
    {
        DontDestroyOnLoad(gameObject);
    }
    public void CreateRoom()
    {
        PhotonNetwork.CreateRoom(createInput.text);
    }

    public void JoinRoom()
    {
        PhotonNetwork.JoinRoom(joinInput.text);
    }

    public override void OnJoinedRoom()
    {
        PhotonNetwork.LoadLevel("SampleScene");

        Player = GameObject.Find("Player");

        DontDestroyOnLoad(PhotonNetwork.Instantiate("Player", new Vector3(-3, -5, 0), Quaternion.identity, 0));

        if (Player.activeInHierarchy)
        {
            DontDestroyOnLoad(PhotonNetwork.Instantiate("Player2", new Vector3(3, -5, 0), Quaternion.identity, 0));
        }
    }
}

is there another way to check if the first Player was instantiated.

[river meteor]

yes it its

GameObject spawnedPlayer = PhotonNetwork.Instantiate(...);
if(spawnedPlayer==null)
Debug.LogError("Player IS NOT SPAWNED!");

for ex

[placid oak]

what is the basic idea of having an authoritive server with photon... how woould i implement that ... like just the basic idea

[ornate zinc]

What you mean, an explanation of what a server is doing?

[placid oak]

the basic idea of a NON authoritive server would be
-> user presses W -> user moves char -> server synchronizes

the basic idea of an authoritive server would be
-> user presses W -> sends request to server -> server checks if possible -> server synchronises the result

so how does it work to implement the authortive server in photon

is there a tutorial or anything

like "hackers" just tell the server 10 times per frame that they jumped => fly "hack"... its just the server didnt check if they are allowed to jump yet

hope it got more clear what i mean

[ornate zinc]

Hm, I mean as long as your game is written correctly, how should a "hacker" be able to tell the server that they jumped 10 times if your code prevents you from jumping? just wondering

[placid oak]

as soon as the code is on client side you cant tell anymore if its a reworked code or not ...

if you have authoritive server it doesnt matter anymore if its reworked or not

you allow on the server the normal gameplay and "everything" (there is always something not perfect)

else gets blocked

[ornate zinc]

If someone really takes the effort of doing this, well, credits to them 😄 but yeah, if you want to have it 100% proof, photon themselves say that a full autority server isnt their thing, but you can always just check the values the players position is sending and check for weird offsets and stuff

[placid oak]

photon themselves say that a full autority server isnt their thing,

How do you mean that

[ornate zinc]

https://doc.photonengine.com/en-us/pun/current/gameplay/hackingprotection

last section

[jovial pike]

public override void OnJoinedRoom()
    {
        PhotonNetwork.LoadLevel("SampleScene");

        if (once == true)
        {
            GameObject Player = PhotonNetwork.Instantiate("Player", new Vector3(-3, -5, 0), Quaternion.identity, 0);
            DontDestroyOnLoad(Player);
            once = false;
        }
        else if (Player != null)
        {
            DontDestroyOnLoad(PhotonNetwork.Instantiate("Player2", new Vector3(3, -5, 0), Quaternion.identity, 0));
            DontDestroyOnLoad(Player);
        }
    }

[placid oak]

ok where is now the difference between photon bolt and normal photon?

[jovial pike]

i want to give up 😦

its too hard

[jovial pike]

he only instantiate the first player

for both players

[ornate zinc]

you are setting your once stuff only on one client

[placid oak]

even if you are false you are only a bit off to be true

like 1 bit... ... was a joke... yeaah

[jovial pike]

and why is it so laggy?

can i fix that?

[ornate zinc]

Welcome to network gaming, if your ocnnection sucks or your friends' connection or both, it will lag. Also depends on your whole game how much data you are sending over the network

[jovial pike]

my game is very small

and i dont think that my internet is bad

[ornate zinc]

I dont know about your network, but laggy is either network connection, too much data or photon is giving free service which will limit bandwidth

[placid oak]

there is written photon bolt requires unity 5 and not unity 4 -.. do you know how to check what i got?

i got the free standalone

version of unity

[ornate zinc]

Which unity version?

[placid oak]

i got pc mac linux standalont 2020.3.9f1 Personal

[ornate zinc]

What do you mean with "do you know how to check what i got"?

[placid oak]

like idk if my unity version works with photon bolt

https://doc.photonengine.com/en-us/pun/current/reference/pun-vs-bolt

[ornate zinc]

Well i guess its a minimum requirement.

[placid oak]

look here at the section unity API

i dont get whats writen there ...

[ornate zinc]

It might be just old

https://assetstore.unity.com/packages/tools/network/photon-bolt-free-127156

[placid oak]

so ye another question came up...

why do so many use the low level api PUN when bolt is available...

like selfmade room management is always a source for errors and problems and a high level api gives you much more stuff by default

[ornate zinc]

tbh, I dont know. I guess most tutorials just start with photon out of the box and not bolt, just a guess

[burnt axle]

Is it better to use frameworks/services like Photon server f.ex. for MMO games or just build your own backend? I guess services takes care of a lot of the infrastructures like load balancing f.ex. which makes it convenient

[ornate zinc]

If you are not a network expert, dont even think about doing your own hacky network thing 😉

[jovial pike]

should I remove Photon from my project if I no longer use it?

[ornate zinc]

Should I remove my garbage from my car if I dont need it? you dont have to, but it will make things messy 😄

[jovial pike]

ok thx

[placid oak]

i have a garbage folder outside of my unity project where i keep stuff and ideas that i may need in future

[jovial pike]

but i mean the Package Photon

for some reason i thought my unity would run slower if i kept it in my project

[placid oak]

unused classes will be thrown away from the compiler anyway so : no

[spring crane]

While it's easier to get higher quality networking through the higher end Photon products, they require you to learn more stuff to make sure you are using the facilities provided by the framework. Recommending a more complex product to someone who doesn't know what problems they are trying to solve is probably not ideal.
From Photon Bolt's description:

Bolt is the perfect product for professional developers and experienced teams. It provides all these teams need to build the next PUBG or Fortnite.
Bolt is rather not suited for beginners. Developing a multiplayer game requires profound coding knowledge especially in case of an authoritative game server architecture.

IIRC Photon Quantum is gated from the public partially for similar reasons, as there are even more things going on and it's expected that you work with ExitGames to some extent.

Users looking into Photon Bolt should probably look into Photon Fusion too btw.

is there a good way to set up a chat system using mlapi

[echo garnet]

When i use photon pun my active ragdolls break like this anyone know why?

[echo garnet]

update the ragdolls parts aren't synced
its a bit weird
anyone know why this is happening with photon?

[inland sand]

are you using photon transform view?

[echo garnet]

yeah

photon transform view classic

[inland sand]

on the parent gameobject or every part of the body?

[echo garnet]

every part

[echo garnet]

I tried only the parent as well and its still broken

should I use photon transform view?

or photon transform view classic ?

[inland sand]

both works the same way ig

[echo garnet]

It doesn't work tho

[proper sphinx]

could anyone help me with an issue i've been having? when another player connects to the game, player 1 controls player 2's character and vice versa. i'm using photon

[lavish forge]

Hey, I am making a game with photon pun and the player is able to join rooms and while waiting in the room before a game starts, the player gets to an other scene. But if the player leaves the room and joins a new room, I need a function that will be called because the Start function is only run at the first scene start. How can I do this?

[prime dawn]

I've started my FPS project a while ago and it's pretty developed at this point but the problem is I was using PUN whole this time. Now that I've realised bolt is a thing, do you think switching PUN to bolt will be hard?

[stiff ridge]

To sync an active ragdoll, I think I would come up with a replacement of the PhotonTransformView. Or at least I would suggest to write one component which aggregates the complete ragdoll into one update / byte[] and then send it along with the rest of the values (via OnPhotonSerializeView). The benefit would be that you have one component which produces a fixed result. A snapshot, which is what you want to sync.
Also, you have to disable the active ragdoll system on the clients just showing the remote character. Otherwise the local machine will apply a ragdoll solution and it "fights" the incoming updates.
And this leads to the other solution: You could possibly skip syncing the ragdoll and just have every client calculate the movement, according to local and incoming movement.

Putting a PhotonView on each node is adding a lot of useless overhead and you only sync positions and nothing more. When you write your own component, you can send velocities and other useful data (as you see fit).

[stiff ridge]

Your scripts need to check whether the character/unit is something you control locally or not. To decide if key/controller input must be applied or not...
The PUN Basics Tutorial covers this, by the way.

[stiff ridge]

If you re-load the scene, Start will be called again. In doubt, you may want to load another scene in-between (something empty)?!
PUN is not syncing re-loading the same scene. That's a known limitation...

[proper sphinx]

i have an (if view.IsMine) statement for the character's script, but that only stopped both players controlling both.

thank you for your help :)

[stiff ridge]

I would recommend switching to Fusion, if you want to switch to a more capable solution. It's our upcoming package and aims to make things easier than Bolt and PUN do.

[proper sphinx]

i love the hobbes profile picture btw

[stiff ridge]

Hehe, thanks. I hope Bill Watterson does not sue me 🙂

that only stopped both players controlling both.
That's odd.
You should test what happens if only one player joins the room. Does it control the instance you instantiated for this player?

[proper sphinx]

if only one player joins the room, the player character works completely fine

as soon as another joins, when you try to look around/move, your character doesn't but you can see from the other screen that those inputs are being applied to the other player's character

if that makes sense

[stiff ridge]

well, i get that something is odd but .. it does not make sense 🙂
it's not just that you forgot to click the window to make it the one to get input from the machine? (sorry, stupid question...)

[proper sphinx]

yeah it's really weird - and, no, i'm certain it's not because i forgot to click! but it would have been funny if that was the issue haha

i think i'll start a new project and chalk that first one down to experience. if it doesn't work on the next project, i'll come back and see if anyone has any ideas

[stiff ridge]

Do both players use PhotonNetwork.Instantiate() to get an instance of a prefab?

[echo garnet]

I am very confused

I dunno how to rly do that

[cunning sluice]

In PUN2 I have two cubes stacked. When I have one cube on top owned by one person, and the bottom one owned by another person. The cube on top begins slightly moving on its own even though the bottom object isn't moving. This doesn't happen when both objects are owned by the same person. Anyone have a solution? I've been on this for 5 hours trying all sorts of things.

Any help would be extremely appreciated

[robust cypress]

Hey, I am using Photon Pun to make a fast paced pvp 2D platformer.
I was wondering what approach to the networking do you recommend when syncing movement.

[cunning sluice]

For assigning the controls, check if the photon view is theirs by using photonView.IsMine

You're probably just getting a photo view in general, not their photon view specifically

[normal marsh]

Hello, im using Photon 2 (PUN) to make a multiplayer game. Im trying to get all the rooms in a lobby then put them in a grid. I got it working, but i want it to refresh when you open the main menu scene. So I want to call the "OnRoomListUpdate" using the "PhotonNetwork.GetCustomRoomList" function, but i dont know what to put in the "sqlLobbyFilter" parameter. I just want to display ALL the rooms in the current lobby, what should i put in the "sqlLobbyFilter" parameter?

[cunning sluice]

tbh for refreshing the list, I just have it call PhotonNetwork.LeaveLobby() and then immediately call PhotonNetwork.JoinLobby() but I'm sure there is a better way to do it lol

also you probably wouldn't need to put anything important in the lobby filter

Just calling GetCustomRoomList will call the onroomlistupdate

so as long as all your room listings are handled in OnRoomListUpdate, I believe it'll just automatically refresh all the rooms like it does the first time

otherwise the leavelobby and join lobby is always an option I've never had trouble with'

Well I guess the lobby thing wouldn't be the best if you're having players in specific lobbies for specific reasons

in my case I just have a main area where I list the servers and you don't invite people to your lobby etc

[normal marsh]

ah, i see. The GetCustomRoomList needs this parameter or else it givs me an error. Ima try the leave and join lobby thing. 1 sec

[cunning sluice]

but I guess the lobby really is just a place beforehand so you can always have them be in a room together etc

[normal marsh]

@cunning sluice Thanks a ton! I just moved the join lobby function from my loading scene to my main menu scene. Now the rooms refreshes when i load in. Thanks for the help!

[valid totem]

Hi, does anyone have any experience with matchmaking and MLAPI, im trying to use the MLAPI Relay but after building and running and setting the network manager to use the relay, im not sure where to go from here. The details on the wiki are sparce, so any pointers would be grealy appreciated 😄

[stable igloo]

Only info I can give you is that Dapper Dino has a video on it. Search Dapper Dino Unity Multiplayer 2021 (he has an older series on Mirror)

[valid totem]

Mirror is similar to MLAPI, right?

[prime dawn]

I'm getting this error, which is weird because it doesn't show anywhere how my scripts caused that error.

it only takes me to photon's script

my scripts are nowhere to be seen here

let's see if rebuilding the solution helps

or whatever this button does

[spring crane]

Are you changing ownership in script?

[prime dawn]

not at all

but maybe it's because I was using an old build

[spring crane]

Does this happen when masterclient changes or something?

Oh it doesn't happen anymore?

[prime dawn]

I don't know yet

I'm making a new build

just to be sure

but it was occuring when I was automatically joining an existing lobby

or room

ah....

still the same

It started happening when I changed my joining script

let me make a ss

[spring crane]

What was the change?

[prime dawn]

well, before it showed a list of available rooms

now I just made it a single click

[spring crane]

Hmm, maybe there is a timing bug there. Are you on the latest version of PUN?

[prime dawn]

yeah

updated it recently

[spring crane]

How are you spawning objects? Do you have scene objects with photonviews?

[prime dawn]

it works for the host

but I can't join that lobby

[spring crane]

How are you joining that room?

[prime dawn]

JoinRandomRoom();```

but the host creates it of course

[spring crane]

How are the player objects created?

Or is it not getting that far?

[prime dawn]

https://pastebin.com/60y18Qn8

[spring crane]

Issue with loading/syncing the scene perhaps, which could cause missing photonviews?

Does it error before OnClick_StartGame()?

[prime dawn]

yes

and the error shows for the person that is trying to join

and before startgame() no scenes are switched

[spring crane]

I would probably look into what viewids are being processed in that photon code

[prime dawn]

but if you are single, just create a room, start the game

no errors appear

[spring crane]

Would also start the process of eliminating everything that isn't necessary to see where the issue might be

You might get better troubleshooting steps in the Photon discord

[prime dawn]

I tried finding one, but those are usually small

[spring crane]

Yes, but full of Photon employees 😛

[prime dawn]

I couldn't find the official one

[spring crane]

You are in it

[prime dawn]

AM I

OH

btw this is my version

that's the newest one...

[spring crane]

Yea mention it in the post

[prime dawn]

well.. it's my time to sleep anyways

will see if I can fix it tommorow

thank you for your help

the staff is AFK love it xD

[spring crane]

It's not always about quantity and speed, but quality 😉

[echo garnet]

uhhhhh

Do you have a link? Im just a bit confused lol

[spring crane]

IIRC they actually don't have a code example in the doc. Odds are it's clearer to just open the transform sync component to see how it's done

[cunning sluice]

In PUN2 I have two cubes stacked. When I have one cube on top owned by one person, and the bottom one owned by another person. The cube on top begins slightly moving on its own even though the bottom object isn't moving. This doesn't happen when both objects are owned by the same person. Anyone have a solution? I've been on this for 5 hours trying all sorts of things.

Any help would be extremely appreciated

[onyx spire]

I'm using SceneManager.LoadScene(0) to reload my scene, but just before doing that, I first close my TcpClient connection using .Close(), however, after the scene reloads, if I create a new TcpClient it works fine but a NetworkStream does not work, it doesn't give me any errors but it also doesn't send or receive any data for some reason. Does anyone know how to fix this issue, or reload a scene in a way which completely resets any socket state? (The socket is closed before reloading and a new one is made later so there should be no problem)

I'm also 100% sure it isn't a problem with the server.

[spring crane]

Worth noting that the only things Unity can affect are its engine objects. Any C# change is merely a side effect of it through garbage collector. If you are holding references to stuff somewhere, you might not be fully releasing stuff

[onyx spire]

Hmm I see, thanks
I'll test some things out in the morning and make sure the socket connection is actually being terminated properly

[echo garnet]

Wait my probelm s cause my rigidbodys aren't being synced right?

[river meteor]

I think so

[proper sphinx]

I already have an (if view.IsMine) statement at the beginning of my player script. unfortunately, all that did is stop one player from controlling both characters

[lofty cedar]

hey what if i use only hubs on layer 2 what will happens on my network

[stiff ridge]

This is likely the physics engine and the network updates getting in a fight over where things should be precisely.
It's enough if the network updates of a remote-owned cube put it minimally into the local cube to freak out the physics. Stacking is problematic in networked physics.
It may be enough to turn on isKinematic on the remote cubes but it might be better to have both cubes controlled by one player (and one physics engine).

[novel topaz]

Hello, i have a very very strange problem. I upgraded my mirror project from 2019.3 to 2020.3.4 and there is one very very strange issue.
When i click "host & client" in the mirror default HUD, my game scene is launched and my player is supposed to spawn in my spawnpoint , this is the case BUT he is strangely bounced forward, exactly as if another player was at the exact same position so the new player is bounced forward to avoid them to intersect. But the problem is that there isn't another player ! When i try to go back on the spawnpoint by moving my player, there is exactly an "invisible" collider (same size as my player collider) which avoid my player to go on this position. But once again, there isn't any other player.
Thats realy strange, since the only cause is that I've upgraded to 2020.3
In the hierarchy there isn't ANY object here, nor in the wireframe scene view. It's totaly wtf. Even if i unactive all the object except my player i can't go in this position...
Anybody have an idea for this very strange problem ?

[cunning sluice]

So if I for example wanted to use the host as the go-to for the physics simulation, how would I prevent the other clients from creating their own physics on the object? When another client moves the cube, do I send that information to the host and then back to my client?

Would it be best to get an authoritative server?

[weak plinth]

Hi, im new to networking, and i wanna make a game like Operation Tango. Does anyone know how to make the two player only lobby with password kinda system? Or can recommend a good Tutorial? I looked into it and it confuses me what to use (MLAPI, Photon, Mirror, etc)

[hasty wyvern]

Hey! I just started making games as well. I am making a multiplayer 3D puzzle game and i have been using Photon. It’s pretty easy to use and there are a lot of tutorials. I’d recommend looking up “unity photon” on YouTube and just kinda looking around. Depending on what game you make can vary the tutorial. Hope this helps lmk if you need any more ideas or have questions

[stiff ridge]

Yes, you'd essentially have to send all actions / input to a server, then get updates. Admittedly, PUN 2 is not well suited to achieve that. Our upcoming network solution is better at that and for a commercial product, I would recommend Photon Quantum...

[weak plinth]

Thanks!#

[cunning sluice]

Alright thanks!

Hi

Could anyone please help me with UDP connection?

I am trying to create a remote for my standalone application. Created a UDP client to send values, it works fine on editor but not working on build.

logcat shows no error. But I am not receiving any data send by the sender (mobile application)

Thanks in advance,

[upper root]

is it a reasonable task to Play two instances of the game while still in the Editor, for the sake of multiplayer testing?

[haughty heart]

It's not possible, if that's what you're asking.

You need to build it and run the build and editor together.

[gleaming prawn]

It is possible, just depends on the sdk you use

Photon quantum and photon fusion both have this as a built in option

[upper root]

thank ya,' that's good of a solution for me

[upper root]

I definitely plan on looking into Photon soon, but at the moment I'm just tinkering with someone who's curious about linking in a simple API with .NET

[verbal lodge]

You can also checkout ParrelSync which allows you to run two editors of the same project at the same time.

[upper root]

oh wow, this looks useful! thank you

Guys how come yesterday i used networkBehaviour and it said it was obsolete but still ran fine but now today i keep the same stuff and it isnt running at all?

[olive vessel]

Are you using UNET?

[silver rune]

yesterday i did

and it worked

[olive vessel]

Jesus fuck why

UNET was deprecated over 2 years ago

[silver rune]

idk how to use other things and no one really answers my questions they just say look at the api

[olive vessel]

There are tonnes of tutorials for Mirror and Photon

Few good ones for Unity's new solution. MLAPI

[silver rune]

using UnityEngine;
using UnityEngine.Networking;

public class PlayerSetup : NetworkBehaviour {

    [SerializeField]
    Behaviour[] componentsToDisable;

    Camera sceneCamera;

    void Start()
    {
        if (!isLocalPlayer)
        {
            for (int i = 0; i < componentsToDisable.Length; i++)
            {
                componentsToDisable[i].enabled = false;
            }
        }
        else
        {
            sceneCamera = Camera.main;
            if (sceneCamera != null)
            {
                sceneCamera.gameObject.SetActive(false);
            }
        }
    }

    void OnDisable()
    {
        if (sceneCamera != null)
        {
            sceneCamera.gameObject.SetActive(true);
        }
    }
}

like for example how would i make that now days?

[olive vessel]

Firstly, get a new solution

[silver rune]

ill use mlapi

[olive vessel]

Ok, it's pretty new but I liked it when I tried it

There's a couple of good tutorials for it too

[silver rune]

ok thankyou ill look at it it wouldnt be hard to re do that script in mlapi right?

[olive vessel]

You need a different using directive, and I think in MLAPI IsLocalPlayer is capitalised

Aside from that, that script should work

[silver rune]

really?

whats the directive?

like

[olive vessel]

MLAPI

[silver rune]

networkBehaviour?

[olive vessel]

No

Using directives are those using tags

[silver rune]

so i change networkBehaviour to mlapi

[olive vessel]

No

[silver rune]

oh ok

is networkBehaviour fine?

[olive vessel]

It's NetworkBehaviour, but yes

[silver rune]

ok do you know what the tag is?

[olive vessel]

?

[silver rune]

using unity.MLAPI?

[olive vessel]

You do need to install it though, it's not built in

https://docs-multiplayer.unity3d.com/docs/migration/install

[silver rune]

oh ok thankyou!

[jaunty veldt]

@echo garnet it says that there is an invalid cast on line 37 of that script.

Could you send the script again by any chance and outline what is line 37?

[echo garnet]

this is line 37

[echo garnet]

this is the script

Should it be a vector2?

For a 2D RB, most likely

Hover over the field you are sending to see its type

@echo garnet if it's a Rigidbody2D then yes, that's probably the issue :)

this is the code does it look good?

[jolly wadi]

it looks good

[jolly wadi]

but i got a question did this error show up for lines 38, 36 ?

[jaunty veldt]

I believe angular velocity for RigidBody2Ds is just a singular number, I'll open unity and check

[jaunty veldt]

Confirmed,

AngularVelocity for Rigidbody2Ds is a float

and rotation should also be a float

[echo garnet]

I dunno what u rly mean by that

But i assume that switcing to vector2 will work

[jaunty veldt]

@echo garnet
latestRot should be a float not a quaternion
also instead of sending transform.position and transform.rotation you should send r.position and r.rotation

Because transform.position is a vector3 not a vector2, and transform.rotation is a quaternion while r.angularVelocity is a float

Wait hold up I'll fix the script in Visual Studio for you

@echo garnet

[limber holly]

I was wondering if UI (healthBar, minimap etc) is A GameObject I have to add to the game scene, or if I have to place it in the Player GO ?

[oak yacht]

Is it possible to schedule network requests on background threads rather than main thread? I'm currently using coroutines but am experience bursts of lag when many requests are being sent

I know Unity has a Job system to do true multithreading but I don't understand it enough yet to determine if it could be used for networking

[spring crane]

Not really networking specific, but I would separate these sort of things into their own gameobjects. UI objects are not really part of the entity they represent.

[limber holly]

@spring craneok then, I Instantiate this UI in the same Fonction of my player ?

[spring crane]

Yea that is fine. I generally manage them separately

[haughty inlet]

is making fast and reliable networking for a 2D pvp shooter game as an indie dev that impossible?

[wind hinge]

can anybody help me with why i cant leave a room in photon

this is my code:

//this VOID is called when the UI leave button is pressed btw
public void Leave()
{
PhotonNetwork.LeaveRoom();
Debug.Log("left room");
}
public override void OnLeftRoom()
{
PhotonNetwork.LoadLevel("mainMenu");
Debug.Log("switched scene");
base.OnLeftRoom();
}

it doesnt switch scene

the game just freezes

[modern drift]

hey, I'm new to networking and I've been watching some mirror tutorials. But some things seem weird to me. I sort of understand how client sends messages to server and vice versa. But in all tutorials they seem to be going for a messy approach where the client and server code are on the same script. i understand this is because there can be a client and server together, but why can't this be split apart to different scripts? does anybody have a different way of doing this?

[junior willow]

Client and server code are on the same script because both the client and server have their own instance of that GameObject, so if you'd like to think of it this way, the player is technically communicating with itself, but just on different instances of itself. So if I have movement code controlled by the client, you ask the server to move that same client, but instead it's the server's instance. You could create a GameManager script that has a singleton that allows your client to pass in your current client's id, then the GameManager does the server request. But just make sure that the client code is always on the client itself, and ANY networking code is on a NetworkBehaviour object

[cinder sluice]

Hey does anyone know off the bat how I should go about making it so that in my multiplayer game that everyone downloads an asset bundle? like for custom player clothing and whatnot
I'm using socketweaver for the actual multiplayer

[echo garnet]

doesn't work

it gives me errors

saying it can't convert float to quaertion

on this one transform.rotation = Quaternion.Lerp(transform.rotation, latestRot, Time.deltaTime * 5);

and how float doesn't cotain a defintion for magitude on this line r.angularVelocity = angularVelocity.magnitude;

[olive vessel]

A float does not have a magnitude, nor can a singular float on it's own be a Quaternion

Vector 3 didn't work before either

i recommend photon realtime

instead

once you get your head around that and write your own wrapper it is a lot better

Post an actual question, you will get a better response, nobody wants to ask you about your issue because that is committing before knowing.

Might I also point out, that you are not in the best place for help regarding MLAPI, they have a Discord server

[weak plinth]

so i'm using fizzysteamworks and mirror attempting to make multiplayer

i have made it so that i can make a host, and join the host through steam on another device

and i have a basic movement script that moves both player prefabs randomly around a cerrtain area

problem is that the players' transform is not synced between the host and client, even after adding a networktransform component to the player prefab

[olive vessel]

@pale coral Cont from #💻┃code-beginner: https://mirror-networking.gitbook.io/docs/components/network-manager#game-state-management

[green tide]

How would a non player object spawn a bullet?

[olive vessel]

Which networking solution?

[green tide]

Mirror

[olive vessel]

https://mirror-networking.gitbook.io/docs/guides/gameobjects/spawning-gameobjects

[green tide]

Ive already through that. So I need to spawn the bullet from a method from the network manager?

So the enemy then calls this method, in order to spawn a bullet?

[olive vessel]

You'd call a method to spawn the bullet on the server

[green tide]

And this method has to be in the NetworkManager script?

[olive vessel]

No, I think it just has to be a Command, sent from any script derived from NetworkBehaviour

I'm sure there are plenty of tutorials online for this though

[green tide]

Well there a plenty of tutorials for spawning objects from the player object, but now for spawning objects from non player objects

The problem is with authority. Non player objects cant for some reason spawn new objetcs

[olive vessel]

But commands can be set to ignore authority

[green tide]

Except for when u use ignore authority

Yes. Ive read some things about avoiding to use this

[muted yarrow]

Hi there ! Is there anyone that knows UNet well ? I have a problem.

[olive vessel]

UNet is deprecated

You should really use a different solution, like Mirror, MLAPI or Photon PUN

[muted yarrow]

I know that. Its a simple project that I want to learn something new.

[olive vessel]

Don't learn UNet, it is deprecated

What's the point of learning something, that is no longer supported or used?

[muted yarrow]

You right. But it's a project that is about to finish. And i faced with a problem.

[olive vessel]

So we've gone from simple learning, to finished product

What's the issue then?

[muted yarrow]

Thanks for answering and help here. I tried a few communities but no one answered.

Let me show the code.

The problem is this. I copied that :

How can i implement my item customization for a LAN game.
I made a local one that player can choose some items like weapons in main menu and when enters to local scene, my warrior reads item index from PlayerPrefs class and Instantiates it and sets parent. For example sets sword for a hand. It works right in local scenes but in UNet story is different.

You know getting item index is something that should execute in client. Client should tell the server hey it's index of my item and server lnstantiate and assign that in all other clients.

How can i implement these process ? I used Command and ClientRpc but didn't work.

https://www.codepile.net/pile/xM4J7B0G

https://www.codepile.net/pile/z4Qwg7O0

https://www.codepile.net/pile/8O5vPGbA

[olive vessel]

You've not even started adding in multiplayer functionality to those classes?

[muted yarrow]

These are what I did for local one and It's work well. But in UNet story is complex

Let me show UNetItemAssign class.

[olive vessel]

Honestly, I am gonna give you one piece of advice, stop using UNet immediately and switch to a newer networking solution, you don't look that far into this certainly not to the point where it's painful to switch

You are shooting yourself in both feet, by using old deprecated systems, that nobody wants to support

Mirror, MLAPI and Photon PUN are all great systems, with great communities of people willing to help

[muted yarrow]

You right. But its just a university project and I should submit it in a few days. That's my fault that I choose a deprecated system. But anyway I have to finish that.

https://www.codepile.net/pile/rowXDkzA

https://www.codepile.net/pile/5QOpMMlw

Every time a player joins to server it should tell index of items and other players send him their itmeIndexes.

[merry nymph]

Hi
So, I'm using MLAPI now cuz UNet has been deprecated...
Everything is fine except that there is no NetworkDiscovery component for mlapi, and according to the docs: "MLAPI does not provide Network Discovery. The UNet Network Discovery is a standalone component that can be used with any networking solution. You can use the UNet Network Discovery to discover a broadcasting MLAPI host and then connect to it with MLAPI."
But so ye I'm confused now how will I use UNet's NetworkDiscovery with mlapi if UNet is deprecated?

Ping me when you answer ^

[wet skiff]

I wish there was a MLAPI playfab party transport protocol in here: https://github.com/Unity-Technologies/mlapi-community-contributions
Someone should totally make it 😏 would totally love that person. (i'm not good enough)

[covert plank]

https://mirror-networking.gitbook.io/docs/guides/server-hosting/aws so i followed this tutorial but i dont think my ports on the aws server are actually open any ideas?

re

Like : 2/8 players in game

[weak plinth]

question with pun RPCs serious issue... I have buffered RPCs they work on any player if they leave room then rejoin... but if the master client leaves then joins again they don't work... anyone who faced such a problem ?

[regal delta]

I believe that's how mirror and MLAPI work. If the host is no longer hosting your RPC's are gonna have a bad time

You'd have to renegotiate who is the "server" and who are the clients...which sounds tricky to do at runtime

[covert plank]

how would i check the ping of a player? ( using mirror )

[olive vessel]

There's NetworkTime.rtt which is the round trip time

[covert plank]

I'll look into it, thank you

[dawn patrol]

does any here use phton that could help me?

photon

.pun

[old nova]

what should l change or add in this script so all client see when a player shoot a bullet photon pun

[dawn patrol]

it MUST be PhotonNetwork.Instantiate

not instaniate

@old nova

[old nova]

l will try it

[dawn patrol]

o.o

that took long

[old nova]

lol

[dawn patrol]

can anybody please help me i have an object im setting a inactive and it is working on one screen but not the other

using photon pun2

[spring crane]

I would avoid rely on the buffer and just send the current state to players when they join

Unless you have some specific use case, it seems like a hack to replay bunch of stuff just to replicate dumb state

I believe there are conditions in which some buffered RPCs are cleared, so I would look into that. Documentation likely has something about this.

Which based on your issue, likely are related to the owner or target of the RPC not being around anymore

[spring crane]

Are you syncing that state?

I don't think PUN tracks active state by default

[weak plinth]

Sorry I fell asleep... But I managed to solve the problem using an event

[frozen hull]

hi

how can i make a player counter using photon?

[short island]

pun or realtime @frozen hull

anyone notice the unity web requests are kind of slow

my azure api is a bit slow from unity

:/

if you want to know how many players there are in a session that is builtin to photon

[frozen hull]

What '' function'' i need to use?

Or wich, idk i'm bad in English

[short island]

for PUN?

to see how many players are in a room

[frozen hull]

Yep

[short island]

PhotonNetwork.CurrentRoom.Players

more specifically PhotonNetwork.CurrentRoom.Players.Count

for the player count

[frozen hull]

So i can use something like countValue.text = PhotonNetwork.CurrentRoom.Players.Count

;

[short island]

yeah but

PhotonNetwork.CurrentRoom.Players.Count.ToString();

[frozen hull]

Thx

[modern drift]

im using mirror and for some reason when i try getting a script on the player prefab it says its null(when it is there). could it be that i ask it too early? or any other reason?

[old nova]

how can l show the panel and destroy gameobject too

[olive vessel]

Doesn't appear to be a networking question, but that should do it, unless the Destroy needs to go after the SetActive

[modern drift]

put the panel.SetActive(true); before Destroy(gameobject)

when u destroy the gameobject u also destroy the script that is on it

so the next line doesnt go off

[weak plinth]

does anyone know what Can not Instantiate before the client joined/created a room. State: PeerCreated means?

and for some reason when i start the game, my player doesnt spawn

not sure if ^ is the reason for that or not.

[old nova]

how get l change this scrip so the deathpanel show before my player with the script on this destroy it

[vital hawk]

oh.. Unity is renaming mlapi now to netcode for gameobjects https://github.com/Unity-Technologies/com.unity.netcode.gameobjects

[spring crane]

Can't create network objects before you have joined or created a room.

[spring crane]

I guess that clarifies the situation in the long run

[verbal lodge]

Yes, see this for the announcement with more information: https://forum.unity.com/threads/announcements-mlapi-becomes-netcode-for-gameobjects.1147601/

[weak plinth]

How exactly do I fix that, cause I'm still not sure what that means tbh

[spring crane]

The client has several states. You can't create networked objects in certain states. To fix it, you just don't spawn objects until the state is a valid one

PUN provides several callbacks you can listen to for state changes and there are properties you can check to make sure you don't spawn objects in a bad state

[weak plinth]

where can i check the states?

[spring crane]

@weak plinth Just spend some time exploring the API https://doc-api.photonengine.com/en/pun/v2/class_photon_1_1_pun_1_1_photon_network.html

There are properties like InRoom and NetworkClientState

[ornate zinc]

What is not working, do you get any debug.log? Give us some information "might not work" is not the best thing to go from

[latent gull]

I'm stupid, sorry 😄 i had Debug.LogError(uwr.error), but i thought that i have Debug.Log(uwr.error), so error "HTTP/1.1 403 Forbidden" maybe problems with permissions, right?

[ornate zinc]

yep, its access permission error

[weak plinth]

i still dont see the errors?

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Photon.Pun;

namespace Com.LuxStudios.FieldsOfBlood
{
    public class Manager : MonoBehaviour
    {
        public string player_prefab;
        public Transform spawn_point;

        private void Start()
        {
            Spawn();
        }

        public void Spawn ()
        {
            PhotonNetwork.Instantiate(player_prefab, spawn_point.position, spawn_point.rotation);
        }
    }
}```

[spring crane]

Well it looks like you are spawning without any regard to the network state, so if that script is present in a scene where the network state can be offline, you would get that error

[weak plinth]

i dont think its offline.

[spring crane]

Or not in a room. PUN will tell you, as you have discovered 😄

Again, use the properties and callbacks to explicitly wait for the state to become valid

[weak plinth]

wdym "not in a room"

[spring crane]

In a PUN room

Can not Instantiate before the client joined/created a room.

[weak plinth]

hold on

it works now

and i dont think i did anything

but now i cant sprint, and move my camera up and down

[cobalt python]

hi guys! i am using photon. How can i make player rb to act more sharper for others? When players jumps and descends it slows down before reaching the ground. It looks too smooth. transform view is disabled.

[ornate zinc]

how do you control the velocity/gravity of this player?

[cobalt python]

void Movement()
        {        
            movementX = Input.GetAxis("Horizontal");
            movementZ = Input.GetAxis("Vertical");
            moveVec = Vector3.ClampMagnitude(orientation.right * movementX + orientation.forward * movementZ, 1.0f) * speed;
            moveVec += Vector3.up * rb.velocity.y;                                         
            rb.velocity = moveVec;
        }

        void Jump()
        {
            if (inventoryMode)
                return;

            isOnGround = Physics.CheckSphere(groundCheck.position, groundDistance, groundMask);

            if (isOnGround && velocity.y < 0)
            {
                velocity.y = -2f;
            }

            if (Input.GetKeyDown(KeyCode.Space) && isOnGround)
            {
                rb.AddForce(Vector3.up * jumpForce, ForceMode.Impulse);
                isOnGround = false;
            }
        }

[ornate zinc]

so you always set the movevector to be rb.velovity.y. Do you change it anywhere or is it just physics based?

[cobalt python]

just physics based!

[ornate zinc]

And where do you set the movement for the network player? long time ago I was using photon, but what is actually handling the transform for others

[cobalt python]

there is photon view (main) component attached and also rigidbodysync script that was in tutorial

i changed now rigodbodysync script to default photon rigidbody view component and it looks better. Strange

i dont know the difference

[ornate zinc]

Maybe its just some settings you can set there

[cobalt python]

yep, i guess i need to tweak this script if i want to use it

thanks

[ornate zinc]

never looked into it, but yeah, maybe there is a smoothing included or something weird

[weak plinth]

So I’m trying to make multiplayer right now using mirror and fizzysteamworks. I’ve successfully made a host button, and the ability to join from a separate pc and separate steam account, when I join it shows both players, but the movement is not transferring between client and host

[olive vessel]

Does the player prefab have a NetworkIdentity and NetworkTransform?

[novel topaz]

Hello, i am using mirror and i have a lobby/room system to allow my player to join a room and ready-up then the game launch, but i can't manage to allow player to join the game once it's "launched".
I try to see through the differents mirror scripts the differents method called when the player successfully join the room and when he can't join the game.
The main difference between both case is that OnServerConnect isn't called on player trying to join the game once it's launched (maybe this is the reason why they can't join the game), whereas OnClientConnect is successfuly called.
Can somebody help me ?

[split zenith]

Anyway to make it into a single method without using mutliples RPCs? (pretty new to photon)

[old nova]

how can l change this script so it update when player leave game

[delicate gyro]

inherit from MonoBehaviourPunCallbacks

then override the OnPlayerLeftRoom method

example:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Photon.Pun;
using Photon.Realtime;

public class Name : MonoBehaviourPunCallbacks
{
    // ...
    public override void OnPlayerLeftRoom(Player player)
    {
        // put code here
        UpdatePlayersList();
    }
    // ...
}

[old nova]

wait what

l'm try to update text when player die

[delicate gyro]

// put your code here and get rid of the line below

[old nova]

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using TMPro;
using Photon.Pun;

[RequireComponent(typeof(TextMeshProUGUI))]
public class PlayersConnectedUI : MonoBehaviour
{
TextMeshProUGUI connectedText;

private void Start()
{
    connectedText = GetComponent<TextMeshProUGUI>();
}

private void Update()
{
    connectedText.text = $"{PhotonNetwork.CurrentRoom.PlayerCount}/{PhotonNetwork.CurrentRoom.MaxPlayers} Players Connected";
}

}

[old nova]

like this

[delicate gyro]

i guess that can work (but youll be updating the text every update )

here's a way but it only updates when a player joins or leaves

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using TMPro;
using Photon.Pun;
using Photon.Realtime; // for 'Player'

// inherit from M-B-PunCallbacks
[RequireComponent(typeof(TextMeshProUGUI))]
public class PlayersConnectedUI : MonoBehaviourPunCallbacks
{
    TextMeshProUGUI connectedText;

    private void Start()
    {
        connectedText = GetComponent<TextMeshProUGUI>();
    }

    private void UpdateText()
    {
        connectedText.text = $"{PhotonNetwork.CurrentRoom.PlayerCount}/{PhotonNetwork.CurrentRoom.MaxPlayers} Players Connected";
    }

    // these are some callbacks that M-B-PunCallbacks give
    // see docs on photon website
    public override void OnPlayerLeftRoom(Player player)
    {
        UpdateText();
    }

    public override void OnPlayerEnteredRoom(Player player)
    {
        UpdateText();
    }

    public override void OnJoinedRoom()
    {
        // prob good idea to update when join room
        UpdateText();
    }
}

[old nova]

thank

[old nova]

one thing Player is not reference in my project

[delicate gyro]

you need the

using Photon.Realtime;

on top

[weak plinth]

yes

[old nova]

l have it on top and it say no suitable method found to override

[delicate gyro]

instead of MonoBehavior in the class line after :, put MonoBehaviorPunCallbacks to inherit from it

[old nova]

look the Player player is not working and update text not working

l only want it to update text when player leave

[delicate gyro]

rename the Update method to “UpdateText”

it’s errorinf because the method doesn’t exist

Update is a unity-reserved method (from M-B-) that is called every update frame so you shouldn’t really use it…

[old nova]

like this “UpdateText”();

[delicate gyro]

private void UpdateText()
{
// keep the code inside of it
}

[old nova]

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using TMPro;
using Photon.Pun;
using Photon.Realtime;

public class PlayersConnectedUI : MonoBehaviourPunCallbacks
{
TextMeshProUGUI connectedText;

private void Start()
{
    connectedText = GetComponent<TextMeshProUGUI>();
}

private void Update()
{
    connectedText.text = $"{PhotonNetwork.CurrentRoom.PlayerCount}/{PhotonNetwork.CurrentRoom.MaxPlayers} Players Connected";
}

public override void OnPlayerLeftRoom(Player player)
{
    “UpdateText”();
}

private void UpdateText()
{
    // keep the code inside of it
}

}

[delicate gyro]

i meant to change the name of the method

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using TMPro;
using Photon.Pun;
using Photon.Realtime;


public class PlayersConnectedUI : MonoBehaviourPunCallbacks
{
    TextMeshProUGUI connectedText;

    private void Start()
    {
        connectedText = GetComponent<TextMeshProUGUI>();
    }

    // v here v 'Update' is a Unity-reserved method name
    private void UpdateText()
    {
        connectedText.text = $"{PhotonNetwork.CurrentRoom.PlayerCount}/{PhotonNetwork.CurrentRoom.MaxPlayers} Players Connected";
    }

    public override void OnPlayerLeftRoom(Player player)
    {
        UpdateText();
    }
}

[old nova]

stop change that emoji

what a script that l can add in my game which leave room and join the same/create a room

[olive vessel]

Plenty of Photon PUN tutorials online, nobody will give you script

[patent oasis]

I was wondering how ready MLAPI (https://docs-multiplayer.unity3d.com/) is opposed to Mirror.

Not for anything complicated, just a small game I want to make for my friends and myself.

[old nova]

why l'm l get this problem

[prime geyser]

anyone know why when i join a server with clients they just clip into the floor and bounce?

using UnityEngine;
using MLAPI;
public class PlayerMovement : NetworkBehaviour
{
    public CharacterController ChrCtrl;

    //Run lines every frame
    void Update()
    {
        if(IsLocalPlayer)
        {
            MoveCharacter();
        }
    }
    //Move the player
    void MoveCharacter()
    {
        Vector3 move = new Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical"));
        move = Vector3.ClampMagnitude(move, 1f);
        ChrCtrl.SimpleMove(move * 5f);
    }
}```

heres the code im using

oh wait im dumb

just realized im clamping it at zero

wait a minute

its clamped to the correct positio

but on the server its still bouncing

on the client its just fine

now im really confused

nvm its working

[sick plank]

I have a StateController that gets attached to each one of my NPC's that controls everything from moving to the actions they're taking.

There is no hot join.

Is there an easy way to convert that to be supported via Mirror? I was hoping I could just put a [Server] tag on the update where UpdateState gets called. But Im not really sure currently. Any help would be great.

[scenic fulcrum]

this might be a pretty noobish question but ... im trying to build an authorian server by hand right now and i am struggeling. Should i build it timer based or tick based and how do i properly send the movement inputs of the clients towards the server when they are not running on the same tick speed?

or if anyone has a good tutorial on that topic i would love to read or watch it

[high night]

@scenic fulcrum
State(t) + Inputs(t) -> State(t+1)

Tick based

Hmm, clients running different tickrates?

Hmm, that'd make the movement prediction weird no?

[scenic fulcrum]

but how do i catch them? I mean, lets say my game runs at 120 fps, so 120 updates per second and my server has a tickrate of 10. I cant just snapshot my inputs 10 times a second and send them over and sending a list of all inputs and their length seems complicated and way to big for a package that gets send often

[high night]

If you wanna do snapshot interpolation, client should constantly keep two ticks

last two

And interpolate

Client will be viewing the past though

[scenic fulcrum]

can you explain this to me ?

[high night]

you have a client time right?

and you have the tick times

you interpolate between last two ticks using client time as interval

[scenic fulcrum]

on the client? yeah. I dont have them on the server as of now because it simply ticks 10 times a second without any timing stuff (as of now) im still new to network development

[high night]

or something based on client time, if you client time is in the future

[scenic fulcrum]

hrm im having a hard tme to understand what you mean, can you write me a simple theoretical example ? :/

also thanks for taking the time to help me!

[high night]

you should have the server time as a float as serverTick * constantDeltaTime

[scenic fulcrum]

oh yeah i have a constant TIME_PER_TICK

whic his currently 100ms

in a simple world, what if my client has pressed 50ms of "move right" and 50ms of no input ... how would i transfer it over to the server?

[high night]

I am kinda busy now, we can voice chat later

[scenic fulcrum]

sure, would love that!

[ivory coral]

Hi, I have a little problem. I'm using Playfab's leaderboard system to hold my data. When I load up the game and click on a button, it Debug.Logs all the scores in the console. The first time is fine, but when I select the button again, it Debug.Logs twice. And then a third time if I press the button again and so on. How can I make it so that it only Debug.Logs once? When I hit the button I run the Login function that let's me login into the sever then run GetLeaderBoard(); right afterwards. It gets the information just fine, but it duplicates it and I have no idea why

[hearty dock]

Photon Fusion question - for anyone who happens to know:
According to the docs:

Fusion automatically calls OnInput() on all SimulationBehaviours implementing the INetworkRunnerCallbacks interface and over which the client has Input Authority - hence the name.
And yet I have a script:cs public class PlayerMover : SimulationBehaviour, INetworkRunnerCallbacks
That has input authority. I know it does because this prints true in both Spawned() and in FixedUpdateNetwork():

print($"We have input authority? " + Object.HasInputAuthority);```
And yet OnInput is not running on the script.
What else should I be checking?

So maybe the docs are just a lie right now, but I got it working with:

if (Object.HasInputAuthority)
{
    Runner.AddCallbacks(this);          
}``` in `Spawned()`

[vague mantle]

should i use dots Unity for rts game online 2d guys ?

[tardy coral]

Hi, I have this issue with networking,
I run my game at Unity and at builded game, I have a ball and 2 players, the ball acts differently on the Unity(Host) and the builded game(Client), it doesn't act same. What can that be about? Network Transform or I dont really know help me 🙂

[jovial cave]

Hey guys, I'm using a springjoint on my client to move my player. For an unknown reason, i'm only able to shoot a player attached 1 of 5 times. It feels like if the collision wasn't fixed at the same spot than my playermodel.

I'm using Mirror btw.

Any idea ?

[stray scroll]

Sounds like you're subscribing on an event each time you click the button.

[ivory coral]

Subscribing?

[stray scroll]

Aha, usually Added through .AddListener(Method) or += Method

[ivory coral]

I see

[red bough]

Is this outdated for unity 2019.1.10f?

[verbal lodge]

Which part do you mean is outdated?

[red bough]

Im asking if it works on unity 2019.1.10f. Sorry for the confusion

[verbal lodge]

Which one? MLAPI? HLAPI?

[red bough]

Any of it

Im stepping into networking and I wanted to check which things I should read first

[verbal lodge]

https://blog.unity.com/technology/choosing-the-right-netcode-for-your-game
This one is still mostly up to date. All of the listed solutions work for 2019.1 as far as I know. MLAPI got acquired by us and is currently an experimental package and is our in-house networking solution for GameObjects/MonoBehaviours.

[limber holly]

I have to create a target window ( UI element with the target name + health ) for multiplayer rpg game. Someone can advise me a way to do this, because I stuck for this morning.

[pine lynx]

Anybody have experience with MLAPI and this NetworkRigidbody script? https://github.com/Unity-Technologies/mlapi-community-contributions/tree/main/com.mlapi.contrib.extensions/Runtime/NetworkRigidbody

[verbal lodge]

Yes

[pine lynx]

I would think so. Thanks for the script Luke! 😄
I was having errors replicating a simple rigidbody player, but I solved it. Somehow I left the "Interpolation time" on the NetworkRigidbody at zero, which in turn caused it to not work properly at all.
Simple error, but hard to spot when I'm completely new to networking in games.

Just one of those times where asking for help cause you to find the error yourself

[verbal lodge]

Oh I see, it's 0 by default if you add it to a GameObject right?

[pine lynx]

Yes!

Maybe there should be a tooltip or warning about a value of zero, but that may be just be me being a bit of a noob

[verbal lodge]

Yeah and I think we can give that a better default value, I'll take a look tomorrow.

[pine lynx]

Thanks! Now that it's working I'm really impressed with how simple it is to set up 🙂
Good work

[wind hinge]

i have a question about OnPlayerLeftRoom and OnPlayerEnteredRoom in Photon

this is my text for "OnPlayerEnteredRoom" :

public override void OnPlayerEnteredRoom(Player newPlayer)
{
base.OnPlayerEnteredRoom(newPlayer);
Instantiate(logText, logImage.transform);
logText.text = newPlayer.NickName + " has joined the room.";
logText.color = Color.green;
}

and this is the text for "OnPlayerLeftRoom" :

public override void OnPlayerLeftRoom(Player otherPlayer)
{
base.OnPlayerLeftRoom(otherPlayer);
Instantiate(logText, logImage.transform);
logText.text = otherPlayer.NickName + " has left the room.";
logText.color = Color.red;

}

but for some reason "LogText" .text = "Nickname has left the room" when the person joined and vice versa. idk why and if you do pls tell me! 🙂

[languid yarrow]

Hello. I use Mirror networking in my game. The game is first person, but I don't know what to do to hide the player model for the owner. If anyone knows the solution, please help. Regards.

[olive vessel]

Have a script, derived from NetworkBehaviour, that lets you check if this isLocalPlayer, if it is the local player, disable the mesh renderer

[languid yarrow]

Thank you for your answer. I have small doubts whether it will work, because it seems to me that only the host mesh will be invisible not only to him, but also to the other players. Anyway, thank you for the answer.

[olive vessel]

With isLocalPlayer? The local bit gives it away

[languid yarrow]

I will use this method. If it doesn't work, I'll keep looking for the answer.

[chilly grail]

Hey something out of topic but im just curious, can you see what functions the driver for your network card exports and use said functions from within a driver of yours?

[minor escarp]

I have a question my photon view transform doesnt work can someone send a working code

Does the script where its movin the chracter have to be in update to use the photon view

[hollow mountain]

Which service would be better for backend? I have to have a simple google sign in and a leaderboard.. firebase or playfab?

[patent fog]

I guess playfab will go a little further for you out of the box. I'd expect a little more setup and coding on the firebase side.

Hi all. what is the best way to make p2p game?
so player1 will create room(and host it on his device), others can see that room in lobby, and join him
thanks

[minor escarp]

Photon

And tutorial from blackthornprod

[minor escarp]

Pls help me

I cant make progress

[olive vessel]

Post problems and questions, nobody will give you code

[jolly wadi]

Welsh cow are you part of unity team?

[olive vessel]

No

[jolly wadi]

Ok

[jolly wadi]

Cause why you so rude

[olive vessel]

Rudeness is in the eye of the beholder, Techy12 provided unhelpful details and asked for code, which is not how this Discord works

If they want help, they should provide errors and full scripts in paste sites so that people can assist them

[jolly wadi]

Oh well

Just ignore him

If you got a problem

[minor escarp]

i am not very good at it sorry

[jolly wadi]

Report him

[olive vessel]

Feel free to report me, but the moderators would say the exact same things as me, you're now going wildly off topic

[jolly wadi]

No report techy 12 I mean

[minor escarp]

pls stop the wels cow

[minor escarp]

sorry

why

i am new

[olive vessel]

There's no need to report him, Techy just needs to provide details about the problems they're having, that's all

[minor escarp]

do you have expierince with photon

can you help me

[jolly wadi]

No I mean if he got a problem don’t have to blatantly take it out on him it is very disrespectful he has barely been in this chat

[olive vessel]

Just go, you're not helpful

[jolly wadi]

And so aren’t you

[olive vessel]

I don't have experience with Photon, but if you provide details about the issues you're facing, others can help you faster

[jolly wadi]

I don’t see you helping him

[minor escarp]

pls thanks for the tips that it doesnt work pls stop

[minor escarp]

ok

[jolly wadi]

You say this when I point out that you are being rude

[olive vessel]

<@&502884371011731486> Can this Shadow guy be dealt with, just incoherent rambling at this point

All I said, was that to get help you must ask questions and provide details of the issue, that's all

[jolly wadi]

Whatever a community moderator does I don’t care if you can’t help don’t talk,simple!

[olive vessel]

How can I help, when the guy literally said "help me" and gave no details of errors? You can't help someone with a problem that they haven't asked about.

[minor escarp]

he is helping me with providing the right way how this server works

[jolly wadi]

He did provide detail

He said his photon transform views don’t work

[olive vessel]

Really? He said 4 fucking lines, not one single error was in those lines

Not one single line of code was provided

[minor escarp]

ok we get it now

[jolly wadi]

He doesn’t need to provide codes for transform views

[olive vessel]

So maybe you both need to check #854851968446365696 to understand how to ask questions

[jolly wadi]

What code is there to provide

[olive vessel]

God knows, but they could have said more than "it doesn't work help me"

[jolly wadi]

Ok idc imma drop it

[minor escarp]

we get it i can give better information p[ls both of u stop

or go do it in a dm or something

i am going to try by giving better info

[spring crane]

Asking for more details is the appropriate response. Bad questions don't need to be reported to anyone. Not engaging with bad questions at all seems worse to alternatives.

Yes

Where is all this aggression coming from? I'm just trying to tell you these things and leaving it at that.

[minor escarp]

ok so my photon view component isnt working i dont know what the problem is it isnt showing on another device if i move my character with photon view component on it its in a resources folder the prefab so that isnt the problem its also shows when join the player can you see but you cant see it moving.

this is my movement code:

[spring crane]

@minor escarp Check #854851968446365696 for how to send long code snippets. Photon View component doesn't sync position in itself, other components like the transform view component do additional syncing.

[jolly wadi]

Don’t use photon view for 2d games

I make your own script and use synchronisation states

You can check out photon documentations on that

[minor escarp]

yeah i forgot in my message transform

[inland sand]

Hi, I'm using mirror with eos and I dunno why but when using online and offline scene slot, it spams null reference error how do I fix?

[minor escarp]

do you have more info

[inland sand]

When using epic online service with unity and using mirror's example scene "tanks", on default settings it works fine but when I add offline scene to offline scene slot and game scene on online scene slot in network manager it spams me null reference error as soon as the game scene loads

And then my unity freezes

[minor escarp]

do you have any other errors

otherwise check if everything is fine with the component

so no blank spaces

i dont know much about mirror

photon how to make your own script and use synchronisation states

[gleaming prawn]

Perhaps you should watch a few youtube tutorials

Because nobody will answer questions that are as generic as these.

But in short, you can implement OnSerializeView (I believe this is the name of the callback) so you can either write (from the client that owns the object) or read data.

[wind hinge]

does anybody know how to sync text in photon unity across all players

i tried syncing it with photonMessageInfo and sync the names in the text but it didnt work(it didnt sync(It showed different names on different clients))

[split zenith]

look into RPCs maybe?

Hey everyone, basically i can't figure out how interest groups work in photon and can't seem to make this work

The "OtherTeamLights" RPC is supposed to disable the lights of this player only on players that are part of the other interest group (ie on the other team)

[burnt frigate]

hi , i need help with unity photon pun , its a bit of a special case so it will be easier if you can dm me, this problem is about having a UI showing a int into a text for each player but idk why only 1 player reiceive the data and the int so for him it show (1 / 5) for other it show (0 / 5) :/

[torpid flax]

has anyone used OVLcloud before for VPS?

[covert plank]

What networking solution should i use if im looking to make a rouge like mmo type game (I need something thats well documented)

also does anyone know if unity's own multiplayer solution is ready to be used?

[modern drift]

there are probably 3 main ones -
photon, mirror and the new MLAPI that is the official unity solution
it is still quite new(so not many tutorials/info yet)
any one of them would be fine for whatever you will need.
unitys solution is ok to be used i think but its not 100% ready and tested yet so you decide.

[covert plank]

do you think unity's solution will be better for long term support?

[modern drift]

yeah probably. if you are just starting out make a simple multiplayer game in it for now but don't go all in. if you are a beginner and not familiar with learning through documentation i might wait till theres more info out there so you wont get discouraged. multiplayer especially is hard. i started learning mirror 2 weeks ago and am having some trouble lol.

take what im saying with a grain of salt tho im not the most experienced

[covert plank]

yeah i was kinda getting discouraged from mirrors api I've been using them for a couple weeks

[covert plank]

unity has amazing api for scripting so far though so if its similar to that I think ill give it a try

I'll definitely make a new project to test it out though

its hard learning all these new things at once but im enjoying it

[modern drift]

but yeah mirrors documentation is kinda meh sometimes like sometimes in the code summarys it says somehing else then what it says on the website lol

[modern drift]

yup, same boat as you

[covert plank]

im about 4 months on unity now

although only recently started putting every hour i have into it

[modern drift]

im on and off for like 2 years i think?

[covert plank]

[modern drift]

but i feel more confident the more i do things

[covert plank]

yeah I'm definitely feeling that
