Merry Fragmas 3.0 Q&A

[richardboegli]

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

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

[Mike-Geig]

@richardboegli

If you have this error:
Spawn scene object not found for 1
UnityEngine.Networking.NetworkIdentity:UNetStaticUpdate()

You need to remove your Network Identity script from your prefab

I think it is a bug in Unity.
https://forum.unity3d.com/threads/merry-fragmas-3-0-stopped-working.448278/#post-2900716
https://forum.unity3d.com/threads/spawn-scene-object-not-found-for-1.333122/#post-2900218

That shouldn’t happen. Are you sure you dragged the player prefab and NOT the player object in the scene onto the player prefab of the game manager?

[richardboegli]

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

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

and for 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 Awake()?? All the advice that they’ve given me is to either not use Unet or not use 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/topics/multiplayer-networking/merry-fragmas-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):

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

.
- The editor's console has these warnings (multiple of them):

- Whichever is the LAN client, the first person camera is not turned on & the player who is the LAN client cannot move, and floats in the air in the screen of whoever is the host.

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

```csharp
<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/indexoutofrangeexception-networkreader-readbyte-out-of-range-problem.368631/
This one says that it's caused by:

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

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?

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)

[BerniceChua]

@""

Remove and re-add the network identity component on the player prefab. Make sure to hit apply

Don’t be like Mike, Apply your Changes!

I found the solution in another thread and applied it to this tutorial.

I spent 1 hour trying to figure this out but I solved it in the most dumb way.

I removed and readded the network identity component to my prefab

I did this because I’ve noticed the Scene ID = 1 field, while all the others where = 0

Don’t know why unity did this change at some point, but fucked up my project.
Yep, had this same problem and used your solution.

Not sure why, as it was a brand new project.

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?

@""

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 @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:

IndexOutOfRangeException: NetworkReader:ReadByte out of range:NetBuf sz:34 pos:34
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):

• IndexOutOfRangeException: NetworkReader:ReadByte out of range Problem - Unity Engine - Unity Discussions
  This one says that it’s caused by:

• you are attempting to connect a client built from older or newer versions of the scripts to a server

• 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?

[BerniceChua]

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

For this error message:

@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.

[Rustygear3]

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.

[Mike-Geig]

Can someone send me a copy of the project getting these index and serialize errors? I’ve never seen that and would like to play with it.

[BerniceChua]

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

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 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.

[Mighteemouse]

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

[Mighteemouse]

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…

You can add me in Collab. Otherwise, dropbox, drive, etc will work too. Be sure to zip it without the library or build folders

@BerniceChua

The other thing: when I asked people in the Unity Discord chat group, everyone was saying that Unity Networking doesn’t play well with ?? All the advice that they’ve given me is to either not use Unet or not use . Is that true???

The thing about this is that in Awake(), the object doesn’t know anything about its networked state. It doesn’t know if it a server, client, local, etc. Otherwise, it is fine to use them together, just not for networking things.

@BerniceChua

and for

I have yet to see those errors ever. I even opened someone else’s project who had those errors and I didn’t get them. Therefore, I suspect something with the library folder. Try closing Unity, deleting the library folder, and then letting it rebuild. See if the problem persists. If so, send me a copy of it because I am curious

@Mighteemouse

Instead I used Collab

Hmmm, perhaps this is a bug with uNet interactions with Collab? I’ve never gotten these errors, but I have also never used Collab with uNet. I know Collab keeps a cache and perhaps that is where our mismatch is coming from. Does anyone else use Collab and also get these issues?

@Rustygear3

The Issue with the health appearing as 0 is only fixed on the client.

Did you spell the SyncVar hooks correctly? It must be an error somewhere in your code. Feel free to post relevant bits for use to check out

@BerniceChua

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.

I have also noticed that before and not just in Unity. Do you happen to have an Asus motherboard in your computer? I do and it has terrible audio noise that has something to do with screen brightness and also proximity to objects in Unity. I know that sounds super weird, but that has been my experience with my motherboard. Eitherway, I know exactly the sound you are talking about, but I’ve never figured out how to fix it. It only happens on this computer for me.

Happy New Years!

@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…

[Mike-Geig]

True, you could set renderers to “Shadows Only” if having first person shadows is important to you.

[Rustygear3]

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

However the values are not being applied to any client players.

Here is the player script I’m pretty sure that the syncvar functions are typed in correctly.

The thing about this is that in Awake(), the object doesn’t know anything about its networked state. It doesn’t know if it a server, client, local, etc. Otherwise, it is fine to use them together, just not for networking things.

I have yet to see those errors ever. I even opened someone else’s project who had those errors and I didn’t get them. Therefore, I suspect something with the library folder. Try closing Unity, deleting the library folder, and then letting it rebuild. See if the problem persists. If so, send me a copy of it because I am curious

Hmmm, perhaps this is a bug with uNet interactions with Collab? I’ve never gotten these errors, but I have also never used Collab with uNet. I know Collab keeps a cache and perhaps that is where our mismatch is coming from. Does anyone else use Collab and also get these issues?

Did you spell the SyncVar hooks correctly? It must be an error somewhere in your code. Feel free to post relevant bits for use to check out

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”:

@any_user

I regularly have errors like this:

IndexOutOfRangeException: NetworkReader:ReadByte out of range:NetBuf sz:8 pos:8

Creating a new build normally solves the problem.

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 [quote=“chrismarch_1, post:4, topic: 605757, username:chrismarch_1”]
mismatch in the number of bytes written and read in an OnSerialze and/or OnDeserialize method
[/quote]

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

@Mike-Geig

I have also noticed that before and not just in Unity. Do you happen to have an Asus motherboard in your computer? I do and it has terrible audio noise that has something to do with screen brightness and also proximity to objects in Unity. I know that sounds super weird, but that has been my experience with my motherboard. Eitherway, I know exactly the sound you are talking about, but I’ve never figured out how to fix it. It only happens on this computer for me.

Happy New Years!

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.
