Building with netcode causes exception in build complaingin about TypeManager, works in editor

When running a build I get the following exception, I would be very grateful if someone could hint at what it means:

Code (logfile):

2. Expected: True

Through some binary search in my repo history I realized it was when I upgraded to latest entity package that I started getting exceptions in builds. (Not while building, but when running built binaries)

I reproduced this by downloading a clean version of the netcode github repo and tried upgrading the entities package of it.

Maybe something was upgraded in the entity versions that I haven't taken care of properly

@timjohansson is this a known issue? If not, would you like me to post a bug? If so, on github or in the editor bug reporting tool?

Used package versions:
"com.unity.entities": "0.9.1-preview.15",
"com.unity.netcode": "0.1.0-preview.6",
"com.unity.transport": "0.3.0-preview.6",

 

Hi

I'm getting the same problem. I tried with initializing the typeManager before any other script executes, but it doesn't work.

 

Downgrading to entitites 0.6 worked for me. I haven't tried any versions between 0.6 and 0.9 so there might be others that also work.

 

Thank You

I will try thad. I hope I can use the latest version of the Unity Physics package despite not using the latest Entities version.

 

I'm on physics 0.2.5, that works with entities 0.6. Looking at the latest physics (0.3.2) looks like it needs entities 0.9, so that will probably not work for you. You might get away with 0.3.1 though!

 

I was on Physics 0.3.1 before I upgraded. This works properly. I'm trying to just downgrade entities. With a bit of luck it could work although the version doesn't fit the requirements.

 

Physics 0.3.2 seems to work with Entities 0.8.0

 

I've hit this as well, sadly – thanks for the help above!
I wonder about the NetCode release and update frequency. Lots of releases at the end of 2019, then the last release in Feb 2020, and now nothing, even though adapting to the latest entities must have become easier and easier…? (And save us tons of trouble)

 

I see in the changelog that there was a null refernce issue fixed in Entities 0.9.1 related to systembase which I use in my code. Any of you guys tried that version?

 

With Entities Version 0.9.1-preview.15 I am still getting

Code (CSharp):

1. OSXPlayer(...) AssertionException: Assertion failure. Value was False
2. Expected: True
3. The TypeManager must be initialized before the TypeManager can be used.

resulting in

World.DefaultGameObjectInjectionWorld

being null.

Edit: Initializing the TypeManager in my ClientServerBootstrap causes the error to go away.

Code (CSharp):

1. public class WorldBootstrap : ClientServerBootstrap
2. {
3.     public override bool Initialize(string defaultWorldName)
4.     {
5.         Debug.Log("Executing multi player bootstrap");
6.  
7.         TypeManager.Initialize(); // <-- Added
8.         return base.Initialize(defaultWorldName);
9.     }
10. }

However, I get a probably unrelated error:

Could not open file MyGameName.app/Contents/Resources/Data/StreamingAssets/livelink-bootstrap for read

Edit 2:

Spoiler: manifest.json

Ok, thanks for sharing the info! That seems like it would be worth trying out and see if I get the same error as you.

 

What's weird though is that on Unity 2020.1.0b7, the player entity is created after connecting, and on Unity 2020.2.0a10 it is not. (In case hat applies to you, @Mikael-H)

 

@florianhanke Thank you very much!

 

@florianhanke You saved me yet again. Thanks!
