New Photon Unity Networking Tutorial Series

PhotonNetwork.time for the projectiles doesn't update every Update() for me, it only updates every 5 or so calls to Update(), resulting in very jagged movement. What can I do about this?

 

PhotonNetwork.time uses a simpler but less accurate way to access the system's time (Environment.TickCount). This updates only every 15ms or so. Could this really cause the issues? It would still give you approximately enough precision for 60 frames/sec.
You could attempt to swap the networkingPeer.LocalMsTimestampDelegate for a method you provide. That could wrap a Stopwatch (e.g.), which is more accurate. You can't wrap Time.time, because that only works on the main thread.

Try this. Modify the end of the NetworkingPeer constructor to setup a stopwatch and add the method below:

Code (CSharp):

1.  
2.         sw.Reset();
3.         sw.Start();
4.         this.LocalMsTimestampDelegate = this.AccurateTime;
5.         this.State = global::PeerState.PeerCreated;
6.     }
7.  
8.     Stopwatch sw = new Stopwatch();
9.  
10.     private int AccurateTime()
11.     {
12.         return (int)sw.ElapsedMilliseconds;
13.     }

 

Hi all! Trying my best to implement this into my game but really having a hard time.. also a 7 month old problem that the game dosent sync time over clients... i think HugoPeters commented on that Nov 13, 2014 tried it and ofc it dident work and seams to work if i try "if not masterclient" instead.. and sorry to say this but i dont like to buy something that dosent work as it should when im trying to learn.
Also has this thread died?
Oh and the videos are greate but i think the scripts help alot more...
I'm so sorry to say all this.. but am i missing something

 

I agree with m4ng4. Some things have to be fixed.

 

We updated the package with PUN v1.60 and a fixed level loading (using PhotonNetwork.LoadLevel() on the Master Client). It is compatible with Unity 5.1 (ignoring non-breaking compiler warnings about obsolete syntax).

There are two known issues open still: Projectiles movement might be jagged on some devices and the round time does not sync for joining player.

We hope the tutorial is useful for you despite some rough edges.
Please watch the videos and based on those, decide if you want to get the project. You get some assets and all the scripts from the videos. All money made from purchases goes completely to Olli (who is super busy but says "hi").

 

Hi,

Thank for your tutorial, I on a problem with collision.

I have made a game where you can fire spell (one every 3 secondes for example).

I check on client side if the spell touch, the issue is:

There is 2 players, A and B

Imagine player_A lag, so the player_B become immobile, the player_A shoot him easily. Then the RPC from A is send to B, to said your are dead, but the player B wasn't at the good position.

I have no idea how to do that correctly.

Wrong decision for me
Solution 1 : Ask player B, are you near that position ? if not, I make no damage, but that make a bad user experience for player A

Solution 2 : Check last value receive from user B, if that is "too old" ... bad user experience too

The only good solution is to make my own server logic with server photon and validate position of each player on server etc... (Game logic). But my skill level for server is near 0. I hope I will found other solution for my game.

 

I Oliver TY so much for all of this that you have created! I was wondering is there any chance you might make a Tutorial showing PHOTON with PLAYMAKER ?

 

Thanks You so much bro. That's what tutorial I've find.

 

Did anybody have fixed the synch time problem?
What about to share some stuff here? Add a weapon, add sounds, Add new Maps

I can start with some:

in ShipMovement.cs:

Code (CSharp):

1. newPosition.y = Mathf.Clamp( newPosition.y, 0.5f, 500f ); //50f so you can fly higher ranges

there are 2 entries ca here: Line 276 and Line 473

In Prefabs/FX/FX_Explosion you can just add a AudioSource to have sound on explosion.

Sound to projectileHit in ShipShooting.cs

Code (CSharp):

1.     public void SendProjectileHit( int projectileId )
2.     {
3.         if( PhotonNetwork.offlineMode == true )
4.         {
5.             OnProjectileHit( projectileId );
6.             this.GetComponent<AudioSource> ().clip = HitLaser;
7.             this.GetComponent<AudioSource> ().Play ();
8.         }
9.         else
10.         {
11.             PhotonView.RPC( "OnProjectileHit", PhotonTargets.Others, new object[] { projectileId } );
12.             this.GetComponent<AudioSource> ().clip = HitLaser;
13.             this.GetComponent<AudioSource> ().Play ();
14.  
15.         }
16.     }

I think when anybody share a bit, then anybody can make some progress.

I think the following parts could be interesting:
Add new Weapon (Rocket Launcher for example)
Add new Pickups (Double damage for example)

I think also ExitGames can earn some money when provide some new Tutorials for this.

 

Hi. Got the package some months ago. Did have a quick look and all looked really good built and commented.

I had already a quite simple random match making in my game working super smoothly but need to build a proper lobby.

The only thing I miss is that with the sync player loading the players are not spawn in specific spawn spots so that they do not overlap. Think of a racing start grid. How could it be managed in the network so that each player spawns in an specific spawn spot?

 

Greetings,
Has anyone gotten Sky Arena to work with WebGL export?
I've gotten another Unity-Photon race game to work with WebGL by moving the 'chatapi folder from plugins to the assets root folder'.
The error was related to websocketstcp(if I recall) but that issue was resolved by moving the chatapi folder in the race game.
Due to the more complex chat system in Sky Arena I can understand why there may be an issue.
I tried both PUN Free and PUN +.
All replies are appreciated.
Thanx

 

have somone a solution to use ragdoll ?=?

 

has this asset been abandoned?

 

Hi Oliver, in SQL Matchmaking, the CreateSqlMatchmakingServer method in Matchmaking script calls the ServerOptions method CreateRoom.
Then, in CreateRoom method you have this lines:

Code (CSharp):

1. MapQueueEntry firstMap = MapQueue.GetSingleEntryInMapQueue( mapQueueString, 0 );

And:

Code (CSharp):

1. roomOptions.customRoomProperties.Add( RoomProperty.Map, firstMap.Name );

So, this means that if player can't find any room available with his search paramaters, always is going to create a Room with the first map? Because firstMap always is going to read the first value in MapQueue.

Thanks in advance for your answer.

 

This is not the focus of this tutorial, sorry. I am not aware of a solution either but you should be able to trigger "ragdoll mode" when the character is being hit/dies.

It looks like this, yes. If the property with key RoomProperty.Map gets updated by maps, then matchmaking will always attempt to find the first map.
This is meant as example usecase. It shows you the properties and methods to use, so you are aware of those and can adjust it to your needs!
Hope that's OK for you.

 

Is there a multiplayer race mode within this project? Also what is the current state of the support on this asset.

 

There is no race mode in the project.
The project is considered "finished" but of course what you learn with it still applies to PUN and you still can simply watch the videos. Based on those, you should be decide if you want the project or if you want to support Oliver for doing the videos.

 

Create ragdoll character and when you die, disable your "real" character renderer and instantiate the ragdoll at same position with rpc.

 

The package wasn't updated in a while but it should run in Unity 5.3.
To update this to PUN 1.74 and newer, you will have to adjust some of the code. There are no major changes in PUN but renaming an API is enough to cause a break.
So: Some assembly work needs to be done but the principle is the same as before.

You can check out PUN Free. For Unity 5, PUN+ "only" buys you a 100 CCU subscription. The two flavors of PUN (free and plus) are otherwise the same for Unity 5. You can buy PUN+ anytime to turn your subscription into a 100 CCU one (or add 100 CCU to any paid subscription).

 

I'm using it in Unity 5.4 and it works like butter : )

 

@Oliver Eberlei
In your Part one lesson 2 you have used Quaternion interpolation for syncing rotation.
But i have used(I making this in 2D i.e only rotation along z axis)
transform.eularAngles = Vector3.lerp(transform.eularAngles,rotationRecived , 180f*Time.deltaTime);
I tried changing 180 to 90 but still rotation looks snappy. How can I sync angles?

 

you are doing the lerp incorrectly, check how to lerp like a pro

 

Thanks for these great tutorials guys. I'm trying to swap out the Ship_Player_07 model (Assets/Models/Ships) with my own model, but I'm having trouble locating where the Ship_Player_07 mesh is assigned to the Ship resource on PhotonInstantiate.
Where and when does this happen and how can I use my own model instead?
How and where does this mesh get added to the empty VisualParent game object?

 

D'oh, brainfart. My bad. I was just looking at the prefab under /Resources in the Project view and of course Unity doesn't show the prefab's child GO's there so I obviously I did not see the mesh there (you have to drag the prefab into the Scene Hierarchy to see the GO with the mesh renderer and then you can modify the prefab and hit 'Apply' in the Inspector).
Please disregard my previous post - but I'll leave it up so others might benefit from it.

 

Hi,
I just bought this, however, I am greeted with an error immediately. From the MainMenu, on Connect....

I bought this, hoping it would smooth out some hiccups I am having in setting up my first multiplayer game, using PUN. Kinda bummed since I dont see many or any PunBehaviors, in the source code. ??

 

@renman3000: The error will be due to a client config problem. You need to setup AppIds for Chat and PUN (Realtime). Otherwise the server (rightfully) turns you away with that error.
You can look up our cryptic codes in the ErrorCode enum. This is "InvalidAuthentication" (I think there should be a better log message for this specific case but maybe it's missing) in Chat.

Have a look at the readme, the tutorial video series and the scenes. There should be pointers, where to setup the AppIds. Sorry, I don't know the project in and out, to my answer is vague...

 

Hello. Many thanks to your product, but unfortunately I have a few stupid questions. I have downloaded asset to make a test build with no changes, and in unity all works, but in the build (windows platform), there is no collision on terrain and flag, object, etc. but I can destroy enemy ship (multiplayer is working) Please tell me that it is ok) logs in attachment. thanks
____________
Oh Its not Ok, this problem doesn't exist in unity version 4.7. First I tested in 5.5
____________
So in 5.3 it works too. it suits me, thanks

 

@toivo3d: Thanks for the updates. Good (or bad) to know it's not working in 5.5.
Oliver is not updating the tutorial anymore (doesn't have the time), so we will have to make do.
We will add a warning in the asset description.

 

Hi does it have matchmaking based on rank system.
and also how does smooth lerp was working ?
i am using smooth lerp but i have some jerky movement.
does the asset have smooth lerp movement?

 

Is package working with new versions of unity?

 

Tested with 5.6.0f3 - PC build worked BUT had to delete Photon stuff and reimported newest PUN+.....Pun free should work.Never did get WebGL to work tho.
.

 

This works for webgl, but the synchronization of the situation leaves much to be desired - perhaps this is due to extrapolation (webgl does not support the udp)

http://3d-techno.com/SkyArena/BuildWebGL/index.html

 

Thanx for replying.Did this work 'outa the box' or did you have to make some changes?
Thanx again!
EDIT:
Got it working- I see what you mean with synch.

 

Hi,

I am learning PUN and bought your Sky Arena few days ago. I am studyiing your codes and have questions

Question #1 - I can't seems to figure out how MultiplayerConnector gets the callbacks from PUN when it does not inherit from PunBehaviour or implements IPunCallbacks ? It appears so "magical". After much thought I come to the assumption that on every callback event of PUN, internally there's sort of BroadcastMessage mechanism to call the same name method on all MonoBehaviour in a scene. Is my assumption correct ? If my assumption is correct, why MultiplayerConnector does not inherits from PunBehavior, what's the advantages ?

Question #2 - I get "Authentication request error : 32767. Disconnecting" and a another related error "SetOnline status called while not connected to front end server" which is caused by ChatHandler. I have created an appId for PUN and another appid for Photon Chat in my Photon account and input the respective appIds into PhotonServerSettings accordingly. Anything else I need to do ?

 

A1: Ultimately, I don't know why Oliver chose to implement the interface and not to inherit from PunBehaviour. Both is possible and more or less a matter of personal preference. And yes, PUN internally either directly calls the method, if the interface is implemented or calls a SendMessage by Unity (slower).

A2: The error code is for "Authentication failed. Possible cause: AppId is unknown to Photon (in cloud service)." You might want to make sure your AppId is copied correctly to the PhotonServerSettings and that you use ConnectUsingSettings(). There are other ways but this is the most convenient.

 

Hi,

Thanks for confirming the SendMessage mechanism in Photon. With your confirmation it is no longer that magical . On why Oliver used MonoBehaviour instead of implementing IPunCallbacks or inheriting from PunBehaviour, I think he is using the same code base to cater for offline mode as well.

On the chat authentication error, there's a small bug in Oliver code where the ChatAppId is unasssigned (empty) when the Connect method is called. Below are the modifications

Code (csharp):

1.  
2. // ChatHandler.cs line 188
3.  
4. public void Connect()
5.     {
6. // modification begin
7.         if (PhotonNetwork.PhotonServerSettings == null)
8.         {
9.             Debug.LogError("Loading settings failed. ServerSettings asset must be in any 'Resources' folder as: " + PhotonNetwork.serverSettingsAssetFile);
10.             return;
11.         }
12.  
13.         if (PhotonNetwork.PhotonServerSettings.ChatAppID.Trim() == string.Empty)
14.         {
15.             Debug.LogWarning("Chat App Id not set in Photon server settings");
16.             return;
17.         }
18.  
19.         ChatAppId = PhotonNetwork.PhotonServerSettings.ChatAppID;
20. // modfication end
21.  
22.         m_ChatClient.Connect(ChatAppId, "1.0", new ExitGames.Client.Photon.Chat.AuthenticationValues(ChatUsername));
23.     }
24.  
25.  

.
I am still learning and would like to know what's the best way to know which region and room a friend is in ? Something like store in player custom properties and make it available as a criteria when matchmaking, possible ?

 

Hi,

Has anyone tried this with Unity 2017?

thanks..

 

Thanks for the series

 

Hi, I imported to the new unity 2017.2 and I have multiple errors, but I can't solve only this one. Can anyone help me?

Assets/Photon Unity Networking/Editor/PhotonNetwork/PhotonConverter.cs(48,9): error CS0433: The imported type `UnityEditor.SceneManagement.EditorSceneManager' is defined multiple times

EditorSceneManager.SaveCurrentModifiedScenesIfUserWantsTo();
EditorSceneManager.OpenScene(sceneName);
EditorSceneManager.SaveOpenScenes();

 

The whole PhotonConverter is no longer needed, so you might focus on removing it, instead of fixing this.
I guess the clash is due to us re-implementing the EditorSceneManager API for older Unity versions. It's not available in Unity 4.x and so we added it (using the old methods in the newer EditorSceneManager API). Due to the compile defines, this probably "leaks" into 2017 (which we expected to be UNITY_6).

Find "EditorSceneManager" and remove it or update the define-checks.

 

It is compatible with mobile?

 

Hello everyone. I see this thread started 3 years ago. Im new to PUN and seek for the best tutorial to start. Are the videos here updated?

 

The principle is still the same, so if you don't mind some minor changes in the API, you can still learn a lot from the videos.
The project wasn't updated though.

 

Hi all,

Just before I end up leaving a bash review, can anyone tell me if this worked for them right out of the box and if so; tell me I'm doing something wrong.

1. It seems like this comes with an older version of PUN (hashtable issues everywhere on load).
2. Importing the new version of PUN fixes hashtable issues (great..),

However there are stop errors on the single player mode

Code (Boo):

1. NullReferenceException: Object reference not set to an instance of an object
2. GamemodeBase.SetRoundStartTime () (at Assets/Scripts/Gamemodes/GamemodeBase.cs:69)
3. GamemodeDeathmatch.OnSetup () (at Assets/Scripts/Gamemodes/GamemodeDeathmatch.cs:25)
4. GamemodeManager.InitiateSelectedGamemode () (at Assets/Scripts/Gamemodes/GamemodeManager.cs:99)
5. GamemodeManager.Awake () (at Assets/Scripts/Gamemodes/GamemodeManager.cs:56)

and via MainMenu.cs

Code (Boo):

1.  
2. Authentication request error: 32767. Disconnecting.
3. UnityEngine.Debug:LogError(Object)
4. ChatHandler:DebugReturn(DebugLevel, String) (at Assets/Scripts/Chat/ChatHandler.cs:567)
5.  

 

Hi astrofox,

we are currently in the process of updating the code base to make it run out of the box with the newest versions of Photon and Unity. Sorry for the current inconvenience.

I will check the errors you encountered as soon as I get home to the code base and report back to you how to fix them.
