Communicate GDscript with Python

+2 votes

I know that this question was already asked on this forum, but I couldn't find any proper answer to it, they just link to the godot-python repository (https://github.com/touilleMan/godot-python) wich dosen't seen to have a documentation, i just wanna know how to do that in code, how to send and get information from one script to another, I am developing a game in godot and a friend of mine is creating an AI in python for the game.

Godot version 3.3.2

Also, when I went to the Godot python repository, it gave me a 404 error - the author probably removed it or something.

If you don't need to have it update very quickly, you can write to a file in gdscript (eg. input.csv), send it to python, use that data as inputs (using keras/tensorflow or something), then write the outputs to a file in python, and read them in gdscript. You do always need the python script to be running in the background, however.

Since you've got two agents and you want them to communicate.
Go with a TCP or UDP server and client respectively.

Simply send the instructions in packets (encrypted of course)
Then open up a communication between the python AI and Godot game through the localhost

Godot
Python

If you wanted a more direct approach then you could technically operate python through Godot's OS.execute() function or python's subprocess class

Actually, that's much smarter than what I suggessted!
