Merry Fragmas 3.0 Q&A

Hi All,

I've watched all three Merry Fragmas videos and would HIGHLY recommend it.
Mike Geig has done an AWESOME job.
Watch on YouTube, Unity's website or Twitch:
YouTube: Live Training - Merry Fragmas 3.0 - Playlist | Direct: Part1, Part2, Part3
Unity Website: Live Session: Merry Fragmas 3.0 | Direct: Part1, Part2, Part3
Twitch: All Videos Direct: Part1, Part2, Part3

Mike's also done the particle effects as a separate video on his own channel: Merry Fragmas 3.0 Particle Settings which I haven't watched yet.

I'm in the process of working through them all the videos at the moment and noticed that there doesn't seem to be a thread specific for Merry Fragmas 3.0.

So here is a thread, to provided support for people working through the videos. As more people finish the videos, they could provide support for others working thru them.

While Mike mentioned to contact him and the others via Twitter, searching thru tweets first to see if someone has asked the question is not my cup of tea.

But incase this ever happens to you....
Don't be like Mike, Apply your Changes!

FAQ
Instead of having to search thru this thread as it becomes larger, this post will hold any FAQs pointing to answer post, I'll group them under headings as it gets larger

1. ERROR: Spawn scene object not found for 1
   UnityEngine.Networking.NetworkIdentity:UNetStaticUpdate()
2. Players health does not reset after dying

 

If your player health does not go back to player health max after dying, check to make sure that you put Player Health script in "On Toggle Shared" under your Player Prefab.

 

Hi @richardboegli, thanks for creating this thread. Sorry for posting in the other thread, when I did a search for

Code (CSharp):

1. IndexOutOfRangeException: NetworkReader:ReadByte out of range:NetBuf sz:34 pos:34
2. UnityEngine.Networking.NetBuffer.ReadByte () (at C:/buildslave/unity/build/Extensions/Networking/Runtime/NetworkBuffer.cs:36)

and for

Code (CSharp):

1. host id out of bound id {0} max id should be greater 0 and less than {0}

, the other thread showed up, and not this one.

"Remove and re-add the network identity component on the player prefab. Make sure to hit apply" << tried this, it didn't work for me. T-T

The other thing: when I asked people in the Unity Discord chat group, everyone was saying that Unity Networking doesn't play well with

Code (CSharp):

1. Awake()

?? All the advice that they've given me is to either not use Unet or not use

Code (CSharp):

1. Awake()

. Is that true???

Anyway, I'm gonna repost my question from <https://forum.unity3d.com/threads/merry-fragmas-3-0-stopped-working.448278/#post-2902042> here so everything's all in one place. (Also, I spent a long time gathering all this data, that's why I didn't refresh that other page lol!)

I have the same error message, but my progress was towards the end of the 2nd video. So it was only until after I did the IK for the hands in the 2nd video (https://unity3d.com/learn/tutorials...-30-ui-graphics-and-animations?playlist=29690), then I started getting these errors. But prior to that step, everything worked properly the same way as the tutorial.

I get them when I click on the Network Manager in the Hierarchy. The errors keep on repeating forever even if I don't hit the play button in the editor.

Other symptoms:

If I use the standalone instance as the host and the editor as the LAN client:
- In the Hierarchy, neither of the players network objects appear.
- In the Scene view, none of the networked players appear (only the one inside the Construct scene appears).
- In the Game view of the editor (which is the LAN client), none of the players appear (only the one inside the Construct scene appears).


If I use the editor as the host and the standalone instance as the LAN client:
- In the Hierarchy, ALL the players appear.
- In the Scene view, ALL the players appear.
- In the Game view of the editor (which is the LAN host), ALL of the players appear.
- (please see the screenshot in the attachment) The FirstPersonController script and the FirstPersonCharacter of the remote/not local player are not active, even if the PlayerBehaviorInNetworking script (in the turorial, this script is called "Player") has them toggled to be active.

For both versions:
- The local player can move, can shoot things, and the kill count increases if the raycasts hit the "remote" player.
- There is this harsh sound like a TV with static. This sound stops when the local player's "feet" leave the ground (like when the player is jumping).
- The remote player is floating in the air, but the idle animation plays. When the "remote" player is shot, it does not play the "death" animation, and just disappears (previously, the death animation was able to play).
- The editor's console has this error message (occurred once):

Code (CSharp):

1. IndexOutOfRangeException: NetworkReader:ReadByte out of range:NetBuf sz:34 pos:34
2. UnityEngine.Networking.NetBuffer.ReadByte () (at C:/buildslave/unity/build/Extensions/Networking/Runtime/NetworkBuffer.cs:36)[/INDENT]

This error message comes out sometimes, but not all the time:

Code (CSharp):

1. <RI.Hid> Failed to create device file: 2 The system cannot find the file specified.

Despite the timing and circumstances of when I started getting the error messages, the error messages seem to lean more towards a networking issue, but I'm not sure. I tried looking online but those solutions seem either unrelated to my issue, or they are just questions in the Unity forums with no answers.

It appears that NetworkReader.ReadByte is an array, and something is trying to access the outside of that array. Is there a way to go into the code to see what's trying to do that? Is this even a good idea??

On Unity 5.5.0f3, running Windows10, if that helps.

Before that, everything worked the same as the videos. So it was only until after I did the IK for the hands in the 2nd video, then I started getting these errors.

Things that I've tried to troubleshoot:
- I went through all the code again and through all the videos again to make sure that everything is the same and that I didn't miss anything, including the placement of scripts & GameObjects in PlayerBehaviorInNetworking script (in the turorial, this script is called "Player").

- https://forum.unity3d.com/threads/understanding-networkreader-readbyte-out-of-range-errors.361115/
The person said that they just rebuilt everything, which I did. I tried refreshing everything in the editor, applied the changes to the prefabs, and saved everything. Then rebuilt the standalone.

- http://answers.unity3d.com/questions/1170290/unet-indexoutofrangeexception-networkreaderreadbyt.html
I didn't see anything on the script that was serialized or deserialized.

- http://answers.unity3d.com/questions/1104570/unet-transport-layer-host-id-is-out-of-bound-0.html
This looks different than what we are going through.

- https://forum.unity3d.com/threads/i...kreader-readbyte-out-of-range-problem.368631/
This one says that it's caused by:

I tried refreshing everything in the editor, applied the changes to the prefabs, and saved everything. Then rebuilt the standalone. Is there a cache or something that's keeping the older version of the scripts? If that's the case, how do we refresh that so it has the latest version?

Any help is totally welcome. Thanks in advance!! ^__^

(By the way, hi @Mike-Geig!! This is Tsai_Ming_Li from Twitch! ^__^)

(Edited formatting for clarity.)

 

Hey guys.
Thanks for Merry Fragmas. It's been a great tutorial.
Like BerniceChua, I started getting IndexOutOfRangeException: NetworkReader: ReadByte out of range: NetBuf sz:30 pos:30.

One thing I noticed was that if I stop and try to rejoin the client multiple times, eventually I get the error about Spawn Position not found... Don't know that it has anything to do with it.

I've started the tutorial over a couple times because in video one I encountered this a couple times but this time I was at the point of binding IK for the hands to the hand points...(In fact I built RIGHT before that it worked great)

 

Hi @richardboegli, out of desperation, I retried this technique of removing and putting back the Network Identity component. This time it worked. I guess the first time I did it, it was still bugged?

Hi @Mighteemouse, based on what people in this thread and this other thread were observing, the timing of when the bug happens is random. Please try what @richardboegli recommended, which is to remove and put back the Network Identity component. (Please note that if you do this, you'll also need to first remove the Player script component, the Network Transform component, the Player Shooting script, the Player Health script, the Network Animator script, and the Gun Position Sync script; then put them all back after. You'll need to do this, because all of the scripts mentioned depend on the Network Identity script, so you can't remove the Network identity script without removing those.)

Anyway, for this error message:

Code (CSharp):

1. IndexOutOfRangeException: NetworkReader:ReadByte out of range:NetBuf sz:34 pos:34
2. UnityEngine.Networking.NetBuffer.ReadByte () (at C:/buildslave/unity/build/Extensions/Networking/Runtime/NetworkBuffer.cs:36)

One of the other things I've seen when I researched for a troubleshooting solution (which I wrote in my original post):
- https://forum.unity3d.com/threads/i...yte-out-of-range-problem.368631/#post-2404110
This one says that it's caused by:

1. you are attempting to connect a client built from older or newer versions of the scripts to a server
2. you have a mismatch in the number of bytes written and read in an OnSerialze and/or OnDeserialize method

I think this might be the underlying reason why there's a bug in Network Identity.

Is there a cache or something that's keeping the older version of the scripts? If that's the case, how do we refresh that so it has the latest version?

 

Putting my questions in individual posts, so it's easier to digest:

For this error message:

Code (CSharp):

1. IndexOutOfRangeException: NetworkReader:ReadByte out of range:NetBuf sz:34 pos:34
2. UnityEngine.Networking.NetBuffer.ReadByte () (at C:/buildslave/unity/build/Extensions/Networking/Runtime/NetworkBuffer.cs:36)

@BerniceChua I ended up doing what @richardboegli had suggested and it got rid of the error but I didn't take good enough screenshots or something and my character models ended up running in place but it connected....
Instead I used Collab (thank you Unity Team.. it allows me to fulfill my saying of "Check in early and check in often") and rolling back to just before I started working on the gun pivot.
You do raise a good question of whether there is some form cache that keeps older versions because the oddity i found when i removed everything (and applied the prefab Mike) as soon as I added the Player script back in, it brought in the Network Identity component right along with it which I found a little.... off..

Anyway.. I'm back to it.. Thank you again Unity Team for Collab.. Source Code control is your friend.

 

Hi everyone. My game system seems to work fine. However the visuals only work correctly if you are the host.
The Issue with the health appearing as 0 is only fixed on the client. I'll show what it looks like on the host and then the client.

Host: Client:
The lobby name and color aren't applied in the client view. Again I will show a comparison between host and client.
Host:
Client:

After I took these pictures, I managed to solve why the text won't face the player. I forgot to disable the PlayerNameCanvas but I don't understand why everything works fine on the host but doesn't work on the clients.

 

Hi @Mike-Geig, thanks for all your help!! ^__^

Sorry, I don't have the errors anymore, because I removed and put back the Network Identity like @richardboegli suggested. But if it comes up again, I'll post the link to my GitHub here.

OR another person who has the error(s) can send his or her work.

I have another question though. What's the best way to test and troubleshoot sounds? In my post above, I mentioned that

The sound seems to come from the player when it touches the "ground", and I turned off Foot IK. Aside from that, where else can people look to troubleshoot that? Thanks in advance.

 

Well crud @Mike-Geig I rolled back. If I get it again, I'll get it to you.

 

Well @Mike-Geig that didn't take long, forgive my newbie-ness of the forums, what is the best way to get you a copy of the project with the error?
I could add you as a user in my Collab and you could get it there (how dare i check in broken code!!! )
It's about 1GB zipped?

By the way, I'm using Personal Edition if you think that may make a difference.

I think that's the last edit...

 

@Mike-Geig - Unintended side effect of disabling capsule (Video 2 - 3m27s) and putting it into remote. Player do not cast a shadow for themselves anymore....

 

I've tested around in order to see which scripts are working properly. The lobby hook script is passing the information to the player.

Thanks, @Mike-Geig!! So that's what they meant in https://forum.unity3d.com/threads/forcing-unity-to-rebuild-the-project.63996/ and https://forum.unity3d.com/threads/understanding-networkreader-readbyte-out-of-range-errors.361115/ when they said "creating a new build":

They didn't mean a build for a new standalone app, they meant rebuilding by recreating the Library folder. Too bad there's no way to do it within the framework, and we have to delete it manually.

I guess recreating the Library folder solves the

Rebuilding the Library folder also seems to have gotten rid of the sound stuttering.

Yes, my motherboard is an Asus X99-A. In the beginning of this tutorial, when I used the FirstPersonController script, as well as the Merry Fragmas 2.0 version, I didn't have this problem though. And when the sound problem appeared, it's only when the player character is on the ground. During the "jump" mode, the stuttering disappears. After rebuilding /Libraries, the sound problem went away too.

 

@BerniceChua
As for the IndexOutOfRangeException with NetworkReader
I deleted the library folder and rebuilt, the build errored. Rebuilt.. Still got the error and @Mike-Geig was able to reproduce it with my project so I logged a bug. I'll let you know what comes of it as soon as I get word.
Thanks again @Mike-Geig for taking the time especially over a holiday to confirm that I'm not an idiot (well, that I can copy and paste code correctly)

 

Thanks! ^_^

I guess when he said this, this was before he got the error again:

 

Yeah, he PMed me and told me he couldn't get it reproduced (I didnt specify hosting on the built client and joining from the editor.. don't know if that was the directions that allowed him to reproduce it or if the stars just mis-aligned.)

I think (based on his inability to reproduce it at first, then on what i saw on some of the other forums posts) that it's some sort of cache somewhere and it's really not consistent at all. (The BEST kind of bugs are the ones that can't be reproduced consistently..)

As an aside, I deleted the library and the temp as suggested in a couple other posts to no avail, I have not however tried what others have said which was "if you restart enough times it will work" just because I feel like it's in the right hands now.

 

Nevermind, the stuttering is still there. When I tested it inside the editor as a single player, it was gone, but I didn't test with the standalone games. When I did local LAN multi-player (both the editor & standalone, AND standalone & standalone), that's when the stuttering appears again. It only seems to appear when there are 2 players or more.

I ended up just commenting out anything related to the sounds inside the FirstPersonController.cs script, and the stuttering went away.

There's also no stuttering when I disable the Audio Source component of the Player, or when I turn off the sound effects audio mixer, but leave the background music turned on.

Hm, after reading what I typed, I suddenly thought of something. The Audio Source component of the Player gets its sounds from FirstPersonController.cs for the footsteps and the jumping and landing sounds. But since FirstPersonController.cs is disabled for not-local players, @Mike-Geig, do you think that messes up the sound?

I'm gonna try that out, and report back on the results.

 

OK, so here are the results of what I tested when I uncommented the audio parts of FirstPersonController:

When I played the game as a single player in the editor, the sounds are all right. Under the "Audio Source" component, in the AudioClip field, the audio clips change to whatever the appropriate sound effects are (i.e. the footsteps while walking, the jump sound while jumping, and the landing sounds while landing).

When I played the game as a single player in the standalone, the stuttering appears. When I turn off the background music, but leave the sound effects turned on, the stuttering continues. When I turn off the sound effects, but leave the background music turned on, the stuttering stops.

When I played the game as 2 players in 2 instances of the standalones, the stuttering appears. When I turn off the background music, but leave the sound effects turned on, the stuttering continues. When I turn off the sound effects, but leave the background music turned on, the stuttering stops.

When I played the game as 2 player, with either the editor as the host and the standalone as the client; or the client as the host and the standalone as the client, the stuttering appears. When I turn off the background music, but leave the sound effects turned on for either the editor or the standalone, the stuttering continues. When I turn off the sound effects, but leave the background music turned on in the editor, the stuttering continues. When I turn off the sound effects, but leave the background music turned on in the standalone, the stuttering stops.

It seems that the sound problems are in the standalone only. I tried totally rebuilding by deleting the .exe file and its accompanying DATA folder to see if something there was affecting it, but same results.

 

Also, there's something funny going on with the character when the editor is in Play mode.

Hey @Mike-Geig, I have a question about dragging and dropping the files into the components. Does it point to the space in memory where those components are stored, or are they pointing to instances of those things? I mean, if I click "Apply" to save my prefabs, do I need to re-drag and drop all prefabs each time?

My test character inside the "Construct" scene seems ok. Its Y-axis is 0, so the feet are touching the floor. Also, the "Gun Pivot" game object is where it's expected to be under "FirstPersonCaracterController" game object.


I double checked that the prefab is saved correctly: In the prefab, the Y-axis is zero, and the GunPivot is the child object of FirstPersonCharacterController (in your tutorial, it's called "Player").


But then... when it is running in Play mode, the Y-axis is above zero, so the character is floating even though gravity is turned on. Also, the GunPivot game object moves to be a child object of FirstPersonCharacter, instead of the player itself.


(If I didn't know any better, the reason why the sound is stuttering is because the character is trying to land on the ground, so that sound just keeps repeating itself.)

Just to be safe, I re-dragged & dropped the FirstPersonCharacterController prefab into the Lobby Manager, but still the same result.

 

@BerniceChua this might seem completely unrelated, but what OS are you running?
There are some strange oddities with Windows10 and certain audio drivers which cause some noise to appear.
I mention this, because I had it happen to me, but only in some applications and under certain conditions.

 

Hi @richardboegli, yes, you're right about my operating system being Windows 10!! I did mention it here (https://forum.unity3d.com/threads/merry-fragmas-3-0-q-a.448473/#post-2902049), but that was a very long post because I was asking about multiple error messages, so probably a lot of people missed it.

Yeah, those were really specific conditions The audio stuttering only happens if the footsteps/jumping/landing sounds are turned on in the FirstPersonController script.

@Mike-Geig also mentioned that there might be an issue with the motherboard, since a stuttering like that happens when he uses Unity in his computer that has an Asus motherboard.

I think I will start over from scratch, see if the footstep/jumping/landing audio clips still give me problems, and see if that gets rid of the strange problem about the prefab not saving properly that I mentioned in https://forum.unity3d.com/threads/merry-fragmas-3-0-q-a.448473/#post-2906852

 

You did indeed. and I did miss it
I was in a rush, so I didn't actually check....

Well I would suggest the following for both @BerniceChua and @Mike-Geig, have a look at this forum:
https://www.tenforums.com/drivers-hardware/12589-windows-10-popping-sound-speakers-2.html
and try a few of the suggestions if the below suggestion doesn't work.
Note: For some reason site doesn't load correctly in Pale Moon (Firefox 27 based), but loads in Chromium.

The solution that worked for me:
1) Press Windows Key and type in "sound" (without quotes) to get sound control panel
2) Right click your playback device and select properties
3) Advanced tab
4) Change the default quality from whatever it is to 16bit 44100Hz CD quality

I believe there is a problem with some Realtek audio drivers and Windows 10.

FYI, I don't get any crackling.

Good luck! Let me know if either of you are successful.

 

Just a follow up @BerniceChua and @Mike-Geig
I got an email today that my case about the IndexOutofRange has been duplicated and forwarded to developers.
Stay tuned!!
thanks again @Mike-Geig

 

I think I have managed to solve the issue with the player name and color not being applied to client players. I simply changed when the OnColorChanged and OnNameChanged functions were being called.

Code (CSharp):

1. using UnityEngine;
2. using UnityEngine.Networking;    //Allows Networking features
3. using UnityEngine.Events;        //Allows use of events
4. using UnityEngine.UI;            //Allows UI features
5. using System.Collections.Generic;    //Allows use of Lists
6.  
7. [System.Serializable]
8. public class ToggleEvent  : UnityEvent<bool>{}
9.  
10.     public class Player : NetworkBehaviour {
11.         [SyncVar] public string playerName;    //Player name
12.         [SyncVar] public Color playerColor;    //Player color
13.  
14.         [SerializeField] ToggleEvent onToggleShared;    //Toggle for shared events, viewable in editor.
15.         [SerializeField] ToggleEvent onToggleLocal;        //Toggle for local events, viewable in editor.
16.         [SerializeField] ToggleEvent onToggleRemote;    //Toggle for remote events, viewable in editor.
17.         [SerializeField] float respawnTime = 5f;        //How long it takes for the player to revive
18.         [SerializeField] CandyCaneMaterialSwitcher candyCaneSwitcher;    //Switches candy cane material
19.  
20.         static List<Player> players = new List<Player> ();    //List of players
21.  
22.         GameObject mainCamera;        //Main Camera for the local player to enable and disable
23.         //NetworkAnimator anim;        //Network animator
24.  
25.         //Occurs on startup
26.         void Start(){
27.             //Gets a reference to the NetworkAnimator
28.             //anim = GetComponent<NetworkAnimator> ();
29.            
30.             //Changes the player color and player name
31.             OnColorChanged (playerColor);
32.             OnNameChanged (playerName);
33.            
34.             //Sets the mainCamera to be the main camera in the scene
35.             mainCamera = Camera.main.gameObject;
36.  
37.             //Calls the EnablePlayer function
38.             EnablePlayer();
39.         }

I'm still unsure about the health being 0 on the client so I just changed the score value text to 3 as a temporary fix.

 

I'm also getting some weird behavior with setting the player name and color.

The OnNameChanged hook isn't getting called on the client for the server character, however it is for the clients own character (checked by adding debug messages). OnColorChanged is getting called for both.

On the server, OnNameChanged and OnColorChanged successfully run for both characters.

Like @Rustygear3 I'm able to get the desired behavior by manually calling OnNameChanged and OnColorChanged from the Start method.

 

Just wanted to say that I appreciate this tutorial a lot. Really cool to see that you can get a multiplayer game up and running in such a short amount of time. This was the tutorial I wanted for the Tanks networking project, but never got.

I'm still confused as to how all of this can work, but I guess it's the high level API that makes it so confusing. All the weird tags and magic functionality everywhere. I'm not even sure if the tags are a Unity feature or a C# feature. I guess I need to do a whole lot of reading to make sense of it.

I also think that I would like to keep a separate prefab for remote players and local players or something like that because all the toggling of functionality and isLocal everywhere in the code seems like it could lead to a lot of confusion down the line, but I have no experience with multiplayer games apart from this tutorial so I guess I need to try and make an actual game first to see what makes sense to me.

I also wanted to note for anyone else wanting to follow this tutorial that I followed it using the character from the Angrybots tutorial. He's similar to the character used in this tutorial and he has the same type of rig and the same animations as the character used in this tutorial. He also comes with a weapon. He's a much better fit than the Stealth character in my opinion. That character is available here:
https://www.assetstore.unity3d.com/en/#!/content/12175

Addendum: For anyone interested in avoiding floaty animations or slipping, here's a long drawn out explanation on how to approach fixing it without using root motion:

I noticed during the tutorial that there was some talk about floaty animations or slipping. Slipping is caused by your character moving at a different velocity than the one that's "implied" by the animation currently playing. So all you need to do to eliminate slipping is to make sure your character always moves at the correct speed for the animation currently playing. Using root motion will do this for you, but in my opinion using root motion makes it feel like you're in the driver seat of a tank or a mech rather than actually in control of your character. I've always hated it and therefore never used it, but I also hate slipping, it's the clearest sign of an unpolished game in my opinion.

So if you're not using root motion, but you still want to avoid slipping you need to make sure you're always passing in values to Mecanim that makes the animation play back at the correct speed in relation to the velocity your character is moving. In this tutorial we pass in our input values directly as the values for speed and strafe. This will not work. For example this will give us 100% slipping if we're moving against a wall or an obstacle because our animation will be playing at full speed while we're not even moving. And we're not even sure if we avoid slipping if we're moving at full speed because we've never checked our values against our animations.

Fixing this requires you to find some magic numbers for your own setup. First of all you need to find the character velocity that fits your game, this would for example be your character's walk and run speed, you completely ignore animations at this point, gameplay first! When you have these values then you try to find the correct values to pass into Mecanim to make the animation play back at the correct speed to match your character's velocity. If you don't have any blend trees then you only need to worry about the animation playback speed, but if you have blend trees then you also need to make sure you're blending by the correct amount based on how your character is moving. Ultimately it's just a lot of trial and error and tweaking, i.e. polish. In my opinion there's no reason why you should have slipping in your game. However, I've never made a multiplayer game so I don't know how this would look when you introduce lag etc.. So for all I know you may need to take special considerations when making a multiplayer game.

Back to this tutorial in particular. For me the slipping was caused by the first person character controller script (which I think is only suitable for very basic prototyping to begin with), passing the input values into Mecanim rather than the character's velocity, and because the animations for my character was not configured the way I wanted them inside Unity. Rotation, position, center of mass etc. were setup to use Mecanim or root motion or something like that in the animations tab for the character. When I changed them so that Unity didn't mess with them (You set them to "Original" or something I think) it immediately looked a whole lot better. I also don't think that enabling "Foot IK" for your animations does anything for you if you do this, I think that's only used if you let Unity mess with your animations, but I'm not sure about this, I at least can't see any difference between having this on or off with my setup. I don't know if the same is the case for the character used in the tutorial, but anyone following this will undoubtably have a lot of the same issues. To fix the slipping you need to make your own character controller or severely alter the existing one, but like I said if you intend to make a shippable game you should get rid of the first person character controller script right away anyway because it's just a very rough example of how to move your character.

Basically, even though it's not related to this tutorial at all, I just wanted to note for anyone wondering that it's possible to fix this problem entirely by just spending some time on it. You'd probably spend more time on this that the entire tutorial which is why it's something you don't spend time on unless you're actually intending to make a polished game.

 

Just checking if you every got a copy of this, if not I have a copy of the project with the same issue I could share.

 

I just tested this project with a friend just to see how and if it worked and to get an idea of how lag would affect it and I'm happy to say it worked perfectly, but there's a noticeable difference in lag between connecting directly to an IP and using the Matchmaker.

I thought the Matchmaker would just help establish the initial connection, but after that it behaved like normal peer to peer, but it seems all communication goes through the Matchmaker and thus it introduces extra lag?

Is there a place I can read about this? Is there something one can do to remedy this? Or is it like this for all online games?

 

I am having a problem where my GunPivot moves to a very strange position in front of my character when i connect another player to the server.As soon as i connect another player to the server my GunPivot moves like 2 units forward and my player model stretches his hand trying to hold the gun. Any ideas what would cause this?

Edit: Actually it seems that it does not matter if i connect or do not connect another player,as soon as a player is created my gunpivot in non local players decides to move a few units in some directions and rotate in some directions till it is floating in front of the character looking to the right >.>

Edit 2: Still not solved the first problem,but now my lobby manager is doing the same as some people above and not summoning the player prefab for any connecting player.Only the host gets a player prefab but any other player spawn one when connected.

Edit 3: 12 hours later... I redone the whole tutorial from the beginning didnt have problems this time.

 

Hey peoples! I love that tutorial series and i like to learn more about the new multiplayer from Unity. I have two questions:

What do i need to think about, if i can see a player shoot a projectile (rocket/grenade) and the other players cant see what is going on there?

Each player can shoot for themself, but over the network the others cant see.
(They also cant see the direction the other player is aiming, so the rocket is flying in a line in front of the player, ignoring where they pointed to shoot.
But each player see for himself its working (so if host or client shoot and just watch own screen, they both feel it works, but if you look at network, it seems he dont want to sync it).

So what is the main explaination i always need to think about if i want to make it visible for both?

There is a new object created in the scene, the rocket.
The rocket have its own script. (explosionpower, blastradius)

 

The Tutorial has been great so far, working on the second one now. You said in the video that you would make the PlayerCanvas prefab available. Was just wondering if that was the case and where I could find it? Or if i should go about recreating that on my own?

Thanks

 

YES i would also like the PlayerCanvas prefab, just so i can see how its setup. please can u link us?

 

For that matter — chiming in late here — is the whole finished project available for download somewhere? I'd love to test the project and see how well it works in its finished state before I invest several hours building it myself. (I'm still not 100% sure which networking layer I'm going to settle on.)

 

Greetings, I have a weird interaction happening when I play online with friends. The non-host players are, after moving from spawn, able to shoot and, in some cases, kill themselves. Did this happen to anyone else? I figured it could be something with the colliders over a network but I'm new to multiplayer networking so I am unsure. Is there a simple solution to not allowing the player shooting to not hit their own collider?

 

Hi everyone.
I just recently joined the Unity community to start learning.
and I'm confused if I should start from merry fragmas I and then 2 & 3? or its okay to just learn the 3? as I played the first video of the merry fragmas 3 and it starts with a complete scene.
The other learning series, 2D Roguelike and Tanks! and Space Shooter, started from scratch.
