Unity team multiplayer using mirror and playfab - unity3d

I want to make a team vs team game using mirror in Unity.
This game goes by rounds, so once one team eliminates the members of the other team, the winner team gets one point and when a team get a certain number of points, the game ends.
To select teamm the player selects in a dropdown menu in a previous scene which team wants, and store it in the PlayerPrefs, and then when the player gameobject is instantiated, I get the PlayerPrefs and pass it to the Game Manager.
playerTeam = PlayerPrefs.GetInt("Team");
GameManager.sharedIstance.AddNewPlayer(playerId, playerTeam);`
Then in the GameManager method I update the numberOfPlayers in team
public void AddNewPlayer(int playerID, int team)
{
ActivePlayers.Add(playerID);
//Cuando se aƱaden los jugadores se incrementa el contador de jugadores en el equipo correspondiente
switch (team)
{
case 0:
numberOfPlayerTeam1++;
break;
case 1:
numberOfPlayerTeam2++;
break;
}
This works as intended and the players are separated in diferent teams so they can play.
At the end I restart the scene to play again but both players now belong to the same team
private NetworkManager Room
{
get
{
if (room != null) { return room; }
return room = NetworkManager.singleton;
}
}
private void RestartRound()
{
Room.ServerChangeScene("InGameScene");
}
This game also uses Playfab and also tried to store there the team info, and get the playerPrefs updated by the GetUserData and SetUserData methods
public void SetUserData()
{
PlayFabClientAPI.UpdateUserData(new UpdateUserDataRequest()
{
Data = new Dictionary<string, string>() {
{"Player", PlayerPrefs.GetInt("Team").ToString()}
}
},
result => Debug.Log("Successfully updated user data"),
error => {
Debug.Log("Got error setting user data Ancestor to Arthur");
Debug.Log(error.GenerateErrorReport());
});
}
public void GetUserData(string myPlayFabeId)
{
PlayFabClientAPI.GetUserData(new GetUserDataRequest()
{
PlayFabId = myPlayFabeId,
Keys = null
}, result => {
Debug.Log("Got user data:");
if (result.Data == null || !result.Data.ContainsKey("Team")) Debug.Log("Team");
else
{
PlayerPrefs.SetInt("Team", Int32.Parse(result.Data["Player"].Value));
}
}, (error) => {
Debug.Log("Got error retrieving user data:");
Debug.Log(error.GenerateErrorReport());
});
}
And then when the Player is instantiated
PlayfabController.sharedInstance.GetUserData(PlayerPrefs.GetString("PlayFabId"));
playerTeam = PlayerPrefs.GetInt("Team");
But the result it's the same. The first round works as intented, but in the next rounds, all player changes to the same team.
Could you tell me how can I persist the team selection data between rounds please?

The PlayerPrefs are variables that are stored in your user registry. So if you're testing on the same computer, these variables ends the same.
So, my question is. Do you test it on the same computer using Parallel Sync or are you using different devices ?

How to generate a random number and make sure it is the same for everyone using Photon in Unity?

Hi Guys I am converting a single player Sudoko game into a multiplayer game (right now 2 players) using Photon in Unity.
The basic logic of the Sudoku game is that there are 300 puzzle data already loaded in it. A random number between 1 to 300 is picked up and the corresponding puzzle is loaded.
But the problem I am facing is even though I have made sure that the same number is getting picked up for both the client and the master server, different puzzles are getting loaded.
So basically I script called MultiManager attached to the MultiManager GameObject in the Sudoku screen.The script looks something like this.
void Start()
{
PV = GetComponent<PhotonView>();
if (PhotonNetwork.IsMasterClient)
{
puzzleIndex = Random.Range(0, 300);
PV.RPC("RPC_PuzzleIndex", RpcTarget.Others, puzzleIndex);
}
gameManager = FindObjectOfType(typeof(GameManager)) as GameManager;
gameManager.PlayNewGame("easy");
}
[PunRPC]
void RPC_PuzzleIndex(int puzzleIndexNUmber)
{
puzzleIndex = puzzleIndexNUmber;
}
So in the GameManager script you have these functions:
public void PlayNewGame(string groupId)
{
// Get the PuzzleGroupData for the given groupId
for (int i = 0; i < puzzleGroups.Count; i++)
{
PuzzleGroupData puzzleGroupData = puzzleGroups[i];
if (groupId == puzzleGroupData.groupId)
{
PlayNewGame(puzzleGroupData);
return;
}
}
}
private void PlayNewGame(PuzzleGroupData puzzleGroupData)
{
// Get a puzzle that has not yet been played by the user
PuzzleData puzzleData = puzzleGroupData.GetPuzzle();
// Play the game using the new puzzle data
PlayGame(puzzleData);
}
And in the PuzzleGroupData class you have this function :
public PuzzleData GetPuzzle()
{
return new PuzzleData(puzzleFiles[MultiManager.puzzleIndex], shiftAmount, groupId);
}
I don't quite get as to whats wrong which is happening. I tried to use other variations like keeping that random number outside of the condition inside of PhotonNetwork.isMasterClient and all, but doesn't work.
If anyone can help it would be great. By the way this Sudoku game was purchased and I am trying to convert it to a mutliPlayer game
Since the master is usually the first one in a room so also the first one getting Start called I think what happens is that your other clients are simply not connected yet when the RPC is called.
Further it might also happen (actually pretty likely) that Start is called before the RPC has the chance to be received.
I would rather actually wait until you have the value and do
void Start()
{
PV = GetComponent<PhotonView>();
if (PhotonNetwork.IsMasterClient)
{
PV.RPC(name of(RPC_PuzzleIndex), RpcTarget.AllBuffered, Random.Range(0, 300));
}
}
[PunRPC]
void RPC_PuzzleIndex(int puzzleIndexNUmber)
{
puzzleIndex = puzzleIndexNUmber;
gameManager = FindObjectOfType(typeof(GameManager)) as GameManager;
gameManager.PlayNewGame("easy");
}
This way
the RpcTarget.AllBuffered makes sure that also clients joining later will receive the call
there is no way you start a game without receiving the random value first

Can't get RunTransaction with Firebase in Unity to work

I'm working on a game in Unity, using Firebase for user and game data.
Everything is fine saving the game to Unity, but in Multiplayer I have the challenge to pair an open game to a unique player 2.
The flow is:
1. You look for a game with a state of "open"
2. If no game is found within X seconds, a new one is created with the state of "open"
I have a query that returns open games (those with state "open")
This query is added a Firebase eventhandler
public void OnButtonLookForOpenMPGames()
{
this.OpenFirebaseGamesAsHost = this.LiveGamereference.OrderByChild("State").EqualTo(WYMSettings.MP_GAME_STATE_OPEN_TO_PLAYER2)
.LimitToFirst(3);
this.OpenFirebaseGamesAsHost.ChildAdded += this.OnOpenMPGameFound;
}
This fires fine in the handler:
private void OnOpenMPGameFound(object sender, ChildChangedEventArgs args)
{
Debug.Log("Looking for open games");
if (args.DatabaseError != null)
{
// handle errors
}
else
{
Debug.Log("Open game found (it may be my own)");
// remove event listener because we got a hit
// it will fire as many times as it's true!
this.OpenFirebaseGamesAsHost.ChildAdded -= this.OnOpenMPGameFound;
if (args.Snapshot.Child("HostId").Value.ToString() != FirebaseAuth.DefaultInstance.CurrentUser.UserId)
{
Debug.Log("Other game than mine found open");
// this.AddDelayedUpdateAction(() =>
// {
// this.MPGameLockInTransaction(args.Snapshot.Reference);
// });
this.MPGameLockInTransaction(args.Snapshot.Reference);
}
}
}
The problem: The handler passes this on to the transaction function, but it fails with an inner exception (Internal Task Faulted) - I've tried many different variations, but can't figure this one out from the official Firebase example.
Problem code:
What I want to achieve is to lock only that game to those two players, the host and the players 2 in this example querying for open games. The State is an int, but here a string for clarity.
private void MPGameLockInTransaction(DatabaseReference mpreference)
{
mpreference.RunTransaction(mutableData =>
{
MultiPlayerGame transactionMPG = mutableData.Value as MultiPlayerGame;
if (transactionMPG == null)
{
return TransactionResult.Abort();
}
if (transactionMPG.State != "open")
{
// game is taken, abort
Debug.Log("transaction aborted");
return TransactionResult.Abort();
}
transactionMPG.State = "game started";
mutableData.Value = transactionMPG;
return TransactionResult.Success(mutableData);
}).ContinueWith(task =>
{
if (task.Exception != null)
{
Debug.Log("Transactionlock to game failed" + task.Exception.ToString());
// Look over again
// not implemented yet
}
else
{
Debug.Log("starting game immediately");
this.AddDelayedUpdateAction(() => this.StartMPGameImmediatelyFromSearch());
}
});
}
This is just a guess but it might be related to threading.
In newer .Net version ContinueWith might end on a thread where most of the Unity API may not be called (including Debug.Log).
Instead you could try and use ContinueWithOnMainThread from the extensions instead which was created exactly for this reason.
With the .NET 4.x runtime, continuations may often execute in the background, whilst this extension method pushes them onto the main thread.
The .NET 3.x runtime didn't have this issue as continuations were contained within the Parse library, which did this implicitly.

How to transfer a VR button ownership using Photon2?

I am currently working on a project and I want to use several buttons in my multiplayer game.
Unfortunately the button can only be pushed locally and it's not synced over the network.
For some reasons the game doesn't trigger the script that should transfer the ownership to the player
I don't really know what's going on and why this isn't triggered ...
I already tried to ad photon tranform views on the moving part and the button itself but without results
private void OnTriggerEnter(Collider other)
{
if(other.name == "LHand" || other.name == "RHand")
{
ChangeOwnership(other);
}
print("trigger entered but not a hand");
}
public void ChangeOwnership(Collider col)
{
if (GetComponent<PhotonView>().Owner != col.GetComponent<PhotonView>().Owner)
{
GetComponent<PhotonView>().TransferOwnership(col.GetComponent<PhotonView>().Owner);
print("changed ownership to: " + col.GetComponent<PhotonView>().Owner);
}
}
If the trigger is actually entered this should show the player as the owner and not the scene...
So if someone has a clue about this I'll take it ...

Photon Unity Turn based Multiplayer game

I am trying to create a simple 2D Turn based multiplayer game using Photon Unity Networking.
It is just a simple turn based game where a player 1 (host) presses his button and it adds his score and changes its turn to player 2 (client) who presses his button to add score and change turn to player 1. It continues to infinite.
I was able to connect two players in the game using the basic Photon documentation. Now I need to add the networking logic of taking turns and changing them.
I searched the internet but I can't understand the RPC and SerializeView of Photon. I am really confused with that. Please Help me. Thank you in future. Here is my GameManager Script
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;
using UnityEngine.UI;
public class GameManager : Photon.PunBehaviour
{
public Text roomName;
public Text player1Name,player2Name;
public List<string> playersConnected = new List<string>();
int scoreP1 = 0, scoreP2 = 0;
public Text scoreTextP1, scoreTextP2;
public Button p1Btn, p2Btn;
int playerTurn = 1;
void Start()
{
roomName.text = SceneManager.GetActiveScene().name;
p2Btn.gameObject.SetActive(false);
p1Btn.gameObject.SetActive(true);
}
public void AddScoreP1()
{
scoreP1++;
scoreTextP1.text = scoreP1.ToString();
ChangePlayerTurn();
}
public void AddScoreP2()
{
scoreP2++;
scoreTextP2.text = scoreP2.ToString();
ChangePlayerTurn();
}
void ChangePlayerTurn()
{
if (playerTurn == 1)
{
playerTurn = 2;
p2Btn.gameObject.SetActive(true);
p1Btn.gameObject.SetActive(false);
}
else
{
playerTurn = 1;
p1Btn.gameObject.SetActive(true);
p2Btn.gameObject.SetActive(false);
}
print("Player Turn: P" + playerTurn);
}

PhotonNetwork.LoadLevel("Room for " + PhotonNetwork.room.PlayerCount);
}
public override void OnLeftRoom()
{
SceneManager.LoadScene(0);
}
public void LeaveRoom()
{
PhotonNetwork.LeaveRoom();
}
public override void OnPhotonPlayerConnected(PhotonPlayer other)
{
Debug.Log("OnPhotonPlayerConnected() " + other.NickName); // not seen if you're the player connecting
foreach (PhotonPlayer _player in PhotonNetwork.playerList)
{
playersConnected.Add(other.NickName);
}
if (PhotonNetwork.isMasterClient)
{
Debug.Log("OnPhotonPlayerConnected isMasterClient " + PhotonNetwork.isMasterClient); // called before OnPhotonPlayerDisconnected
LoadArena();
}
}
public override void OnPhotonPlayerDisconnected(PhotonPlayer other)
{
Debug.Log("OnPhotonPlayerDisconnected() " + other.NickName); // seen when other disconnects
foreach (PhotonPlayer _player in PhotonNetwork.playerList)
{
playersConnected.Remove(other.NickName);
}
if (PhotonNetwork.isMasterClient)
{
Debug.Log("OnPhotonPlayerDisonnected isMasterClient " + PhotonNetwork.isMasterClient); // called before OnPhotonPlayerDisconnected
LoadArena();
}
}
}
RPC is basically a way of invoking a function on a remote client.
Usually in a multiplayer setup you'd want your MasterClient to control the flow of the game. So, when two players join a room, what you need to do is from your MasterClient, decide which player goes first and then call a RPC function from MasterClient telling both client whose the first turn is. Then whichever player's turn it is, just activate its button and let them add score (Send RPC to MasterClient as well for that, so that everyone can stay in sync.) and the update turn and tell everyone via another RPC and so on.
though you can also use Events for such cases, they need less preparation to be used.
Both in a nutshell:
RPC, Remote Procedural calls, is used to call a certain method to all or certain clients/users in the same room/level. Example like this, you might want to use RCP to update the teams score if a team scored a goal.
SerializeView is used by PUN to synchronize and read data a few times per second, depending on the serialization rate. Example like this, you will use this to get and read to see each other's data like how much points another player have in realtime.
both of these functions are practically similar, but their use is entirely different.
There is more information about RCP and SerializeView on the Photon Website Link

Project Tango won't relocalize

I am trying out Area Recognition using Area Learning with predefined ADF files using Project Tango in Unity3d. I use the script from this tutorial as the basis, but for some reason it won't relocalize.
using UnityEngine;
using System.Collections;
using Tango;
public class TestADFFile : MonoBehaviour, ITangoLifecycle
{
private TangoApplication m_tangoApplication;
public UnityEngine.UI.Text statusText;
public string adfName;
public void Start()
{
m_tangoApplication = FindObjectOfType<TangoApplication>();
if (m_tangoApplication != null)
{
m_tangoApplication.Register(this);
m_tangoApplication.RequestPermissions();
}
}
public void OnTangoPermissions(bool permissionsGranted)
{
if (permissionsGranted)
{
if(AreaDescription.ImportFromFile(System.IO.Path.Combine(Application.streamingAssetsPath, "adfs/" + adfName))){
statusText.text = "success!";
}
else{
statusText.text = "fail!";
}
AreaDescription[] list = AreaDescription.GetList();
AreaDescription mostRecent = null;
AreaDescription.Metadata mostRecentMetadata = null;
if (list.Length > 0)
{
// Find and load the most recent Area Description
mostRecent = list[0];
mostRecentMetadata = mostRecent.GetMetadata();
foreach (AreaDescription areaDescription in list)
{
AreaDescription.Metadata metadata = areaDescription.GetMetadata();
if (metadata.m_dateTime > mostRecentMetadata.m_dateTime)
{
mostRecent = areaDescription;
mostRecentMetadata = metadata;
}
}
m_tangoApplication.Startup(mostRecent);
}
else
{
// No Area Descriptions available.
Debug.Log("No area descriptions available.");
}
}
}
public void OnTangoServiceConnected()
{
}
public void OnTangoServiceDisconnected()
{
}
}
The statusText is set to "success" so apparently the ADF is successfully loaded, right?
You're doing it right. Relocalization with area learning mode off works very quick. But relocalization with area learning mode on takes quite a while. You have to walk around up to 3-5 minutes until the relocalization works. Don't give up. I had the same problem. But in the end, it works!
Is not an answer I think, but just a checklist of things I would check.
Check that the ADF to relocalize is the right one, you may be loading an ADF from a different area.
On the TangoManager component check if Enable Area Descriptions is set to true.
Also check if the scene is set up correctly with all tango components required like: RelocalizingOverlay.cs, TangoApplication.cs
Also as a personal note I have noticed that ADF sometimes take quite a while to relocalized and sometimes they don't relocalize at all.
I think the reasons are that the room has change in someway or the lighting is very different, by different I mean maybe the day you recorded that ADF was a very sunny day and the day you are trying to relocalize is cloudy.(Again this are just theories of mine, I got from my testing)
