NetworkBehaviour in External DLL

Hello together,

I develop my Game with Visual Studio and compile it to an DLL, to place it in my Unity Plugin Folder and use it in Unity. My game is a multiplayer game so I have to use, since Unity 5.2, UnityEngine.Networking.NetworkBehaviour from "...\Unity\Editor\Data\UnityExtensions\Unity\Networking\UnityEngine.Networking.dll". But after switching my Classes inheritance form MonoBehaviour to NetworkBehaviour, these class are no longer avaible in UnityEditor.
And I am getting follwing error:

Code (csharp):

1.

Had someone the same problems? Or has an idea to solve this problem?

Greetings,

Ok, thank you.
Will this ever be possible or not?

I've investigated this myself and it seems there is no reason the UNetWeaver could not be made to run on an external DLL as a post-build step, except that it currently filters for assemblies starting with "Assembly-". Could Unity release a tool to post-process DLLs manually so they can be shipped in the asset store with NetworkBehaviours?

Using DLLs with UNet is further complicated by this bug: https://issuetracker.unity3d.com/is...t-recognized-if-they-inherit-networkbehaviour

 

@deemen

I created a small program which can post-process the DLL, using Unity's unet weaver DLL. You just give him the path to unity installation, and he will automatically load unet weaver DLL, and invoke a method inside it, which processes DLL.

You can find it here => https://github.com/in0finite/UnityLibraryPostProcessor.

I use it in uGameCore asset and in a couple of games, and it works perfectly.

 

Thanks for this! Unfortunately it doesn't work for me

Code (CSharp):

1. "C:\Program Files\Unity\Editor\Data\Mono\bin\mono.exe" UnityLibraryPostProcessor.exe "C:\Program Files\Unity\" Assembly-<assemblyname>.dll
2. WARNING: The runtime version supported by this application is unavailable.
3. Using default runtime: v1.1.4322
4. The assembly mscorlib.dll was not found or could not be loaded.
5. It should have been installed in the `C:\Program Files\Unity\Editor\Data\Mono\lib\mono\1.0\mscorlib.dll' directory.

If I copy over from mono\2.0 to 1.0 it says

Code (CSharp):

1.  
2. WARNING: The runtime version supported by this application is unavailable.
3. Using default runtime: v1.1.4322
4. Missing method System.Reflection.Assembly::op_Equality(Assembly,Assembly) in assembly C:\Program Files\Unity\Editor\Data\Mono\lib\mono\1.0\mscorlib.dll, referenced in assembly <dir>/UnityLibraryPostProcessor.exe
5.  
6. Unhandled Exception: System.MissingMethodException: Method not found: 'System.Reflection.Assembly.op_Equality'.
7.  

I call the program like this

Code (CSharp):

1. "C:\Program Files\Unity\Editor\Data\Mono\bin\mono.exe" UnityLibraryPostProcessor.exe "C:\Program Files\Unity\" Assembly-<assemblyname>.dll

Do I need a specific mscorlib.dll or do I call something incorrectly?
