This project served as a way to connect Python with Unity 3D. However, in my current project (https://github.com/NumesSanguis/FACSvatar) I switched to ZeroMQ for this, which is more stable and more robust than the code found here. So I would recommend looking at that code.
A Python 3.6 client with asyncio for asynchronous execution, that can send to and receive JSON messages from a Unity3D server (Unity 2017.2.0f3).
-
Start Unity 3D from
BasicUnityPython& press play (you should see in Unity: Server is listening) -
Open terminal in this folder and run:
python client_asyncio.py, you should see in Unity:"Hello World x"/ Python terminal:Send: {'welcome': 'Hello World x!'} Received: {'unity': 'Unity sends its regards x'} Close the socket
- Open terminal in this folder and run:
python server_asyncio.py - Open another terminal here and run:
python client_asyncio.py
- Start Unity 3D from
BasicUnityPython_aiohttp& press play - Open terminal in this folder and run:
python client_asyncio_aiohttp.py(you should see in Unity:"data_stuff": x/ Python terminal:message: {'receive': 'received x'})
- Get JSON object addon in your Unity project: https://assetstore.unity.com/packages/tools/input-management/json-object-710
- Add TCPTestServer.cs to your project from this Github if you want JSON support, or: https://gist.github.com/danielbierwirth/0636650b005834204cb19ef5ae6ccedb
Communication over SocketIO is inspired by tawnkramer/sdsandbox (https://github.com/tawnkramer/sdsandbox/tree/master). However SocketIO (both the original with FLASK and modified with aiohttp) was found to be way slower.
Measured with a phone stopwatch for 10 seconds:
- Just asyncio: 7738 messages received from Unity
- asyncio with SocketIO and aiohttp: 97 messages received from Unity (seems to be faster than no asyncio with FLASK)
Therefore simple asyncio about 80 times as fast with this unprofessional measurement.
