Need help, part of unity inspector missing.

[firepizzaninja]

I am making a multiplayer game in unity using fusion.
My issue is the following.
This is what I am getting:

But this is what I should be getting:

I am also receiving the following error:

I’m hitting the same issue. If you’re following the Fusion 100 guide Fusion 2 1 - Getting Started | Photon Engine it mentions installing com.unity.mono.cecil, have you done that? And if so, does it fix the issue?

yea i did that, it didnt work

[gsylvain]

The issue occur on unity 2022.3.23. It is NOT occuring on 2022.3.21.
Similar issue: Cannot open PhotonAppSettings on 2022.3.23f1 · Issue #21 · oculus-samples/Unity-Discover · GitHub

Photon discord: Discord

tl;dr: photon has a fix in progress

[davidborbis]

Have they released an update yet or posted a temporary workaround? I don’t have access to that channel

@davidborbis

The recommendation is to downgrade to Unity 2022.3.21 until they release a fix. No ETA at the moment.

[gsylvain]

@michielproce @davidborbis The fix is available - check the new quantum version 2.1.8.1

[Product]

The fix is only available for Quantum but not for Fusion…

[harshvardhanv98]

This issue sucks. Please fix

[Saeed-Barari]

found a solution:
Add bool isPropertyTypeAManagedReference = false to the script at “Assets/Photon/Fusion/Scripts/Editor/Fusion.Editor.cs”

although a more delecate solution would be

#if UNITY_2022_3_25
      public delegate Type GetDrawerTypeForTypeDelegate(Type type, bool isPropertyTypeAManagedReference = false);
#else
      public delegate Type GetDrawerTypeForTypeDelegate(Type type);
#endif

(replace the unity version with your current one)

[GamerRealities]

Yes!! The above post worked, but it was different for me using Fusion 2.0.0 and Unity 2023.2.19f. I noticed the error was about a legacy version of GetDrawerTypeForTypeDelegate, so I went to line 6586 of Fusion.Unity.Editor.cs (Found in the Engine folder not the Script folder for me) and changed the line from this:
private delegate Type LegacyGetDrawerTypeForTypeDelegate(Type type);

to this:

private delegate Type LegacyGetDrawerTypeForTypeDelegate(Type type, bool isPropertyTypeAManagedReference = false);

Now my networked components work and I can use the project with multiplayer again!

[sharatachary]

Thanks @Pk125 your solution worked for me.

[BharatMakwana13]

Thanks @Pk125 it’s work for me.

[theFinder]

Thanks @Pk125 it’s work for me too.

[milan_unity711]

It’s fixed in the latest Quantum version 2.1.8.1

[DirtyFred]

yeah that worked for me too!

Thank you.

How did you find this though? the file has 10K plus lines of code…

[yotingo]

Thanks for this!

@GamerRealities Had the fix I needed for Fusion 2.0
