PythonNet VS NuGetForUnity

I looked into using .NET as a "backend" and the pythonnet library to bridge the gap, but unfortunately that library does not support async. To properly support it would require some kind of integration with the asyncio event loop APIs or implement the AbstractEventLoop interface and some how make it thread-safe - not even sure that's possible with the API design of asyncio itself.

If you're running the python within C# using Python.NET, then you're somewhat within-process and there are ways of sending the data across. (Return objects, channel/queues, whatever fits your use case.)

I was going to make a joke about Python .NET core .. but .. apparently it's a real thing.

I am not set on .NET, but just curious, so thanks for the suggestions. Interesting that it's billed as cross-plaform, but doesn't do it that well. I just searched 'python wrapper for .net' and found PythonNET. Also, it seems yes IronPython is active.

I created a Django based python project that interfaces to TIA Openness to create some Remote IO. To do this I use the pythonnet library. so that I can load the Openness DLL.

For nuget packages: There is an open source package "nuget for unity" that you can use to install nuget packages into your unity project

You can use Json.Net /Newtonsoft's solution ofr Json serialization and deserialization, it's pretty much a standard for json in C# projects. Use this https://assetstore.unity.com/packages/tools/input-management/json-net-for-unity-11347 Or Download from Nuget using https://github.com/GlitchEnzo/NuGetForUnity

Hey, thanks for the comment. At this point I'm just trying to figure out how to add it to my Unity project. I'm new to adding pre-compiled DLLs to a Unity project. There are the files on the GitHub repo and the NuGet Package. I attempted to install via the NuGet Unity Package Manager but it gave me a ton of Namespace/Type Not Found errors. Same thing happened when I tried just moving the files from the GitHub repo into my Assets folder. I might just need to somehow learn more about how to install pre-compiled .NET packages into Unity. But if you have any thoughts or any directions to point me in, I would be in your debt. Thank you!

Download the packages from https://www.nuget.org/packages/pythonnet/3.0.0-preview2021-03-03 and https://www.nuget.org/packages/System.Security.Permissions/ . Alternatively you can also install a unity-nuget plugin : https://github.com/GlitchEnzo/NuGetForUnity and install from there, This will allow you to skip the next step as the dlls are already unpacked if you use this tool. Remember to use the 3.0.0 preview version as the older versions are not compatable with Unity (reloading/reruning the game crashes the entire program)

Steps: - Create a folder in Assets for storing the dlls that are needed. - Download the packages from https://www.nuget.org/packages/pythonnet/3.0.0-preview2021-03-03 and https://www.nuget.org/packages/System.Security.Permissions/ . Alternatively you can also install a unity-nuget plugin : https://github.com/GlitchEnzo/NuGetForUnity and install from there, This will allow you to skip the next step as the dlls are already unpacked if you use this tool. Remember to use the 3.0.0 preview version as the older versions are not compatable with Unity (reloading/reruning the game crashes the entire program) - The packages contain the dlls so you need to unzip them and copy over the Python.Runtime.dll from \lib\netstandard2.0 inside the unzipped folder and System.Security.Permissions.dll from lib\net461\ which pythonnet depends on. Copy these dlls into the folder in Assets. - Download an embedded python (I was able to get it working with python 3.7, not sure how well the other versions work) and install pip and any other modules you want. Move the folder into the StreamingAssets folder in Assets (create one if you don't have one). - Change the Api Compatability level to 4.x. This can be found in Edit -> Project Settings -> Player -> Other settings -> Api Compatability level. - Create a script to use python. You need to point to the python (Python3x.dll for windows, libpython3.x.so for Linux and libpython3.x.dylib for Mac where x is the version) in the streaming assets folder. - More info can be found here: https://github.com/pythonnet/pythonnet#embedding-python-in-net here is a sample script for running numpy.
