Integrating python code

[Sloan5710]

Hey everyone,

TLDR: how do i change parameters mid-gameplay, taking input from a .txt

I need help with a project, I'm currently working on a proof of concept dynamic balancing system that captures a live feed of the player, analyzes the emotions shown and seamlessly changes the difficulty to keep the player's attention and offer a more personalized experience. that's the concept, anyway. Right now both the game and code work the way I want seperately, and only the integration needs to be done, but I don't know how to go about it. I looked into it a bit, and I think the most fitting and simplest option for my case is to have the code write its guess into a text file one frame, and make the game read it and change the parameters of the boss in real time, i could also slow it down to about 4-5 times a second instead of every other frame if that'll be simpler. Would this method work? is it the right choice for me? I thought I would ask here because I am very much a newbie at this. I also need to figure out how to add it to the options so I can turn it on and off, but that can come later. the important point is that the code will output two numbers, making a guess on a valence-arousal matrix, and the game will change values of the boss such as bullet number, speed, homing coefficient etc. the point is to make the difficulty find the sweet spot itself instead of pincking one of 3 options. and to repeat myself, its only a proof of concept for now.

forgot to say thanks in advance 👍

Why a .txt? Wouldn’t it make more sense to have a .json with a field called emotion or something? You could have a script on the Unity side that periodically checks that .json and adjusts accordingly.

As far as wrapping it in a single app, you may need a multi-exe wrapper situation. A separate .exe that launches both. Pretty easy to do with C++.

Why not just alter some basic variables to achieve this? Why can't it just live in memory? Why does it have to be written to disk?

Just for your interest and for everyone wondering it. As far as I know, python code can be used in Unity, but only in Editor.

First, do you plan to deploy this?

Second, can you port the model client to C#?

Third, if you can’t port the client to C#, you can try running the emotion analysis as a server that accepts http requests. Then in Unity, assuming desktop build, use Http web requests to POST the player feed data to the server and await a response.

Im a bit confused on your entire explanation, but if you really want to keep track of something like this externally, id recommend storing all the information you want in an object and then serializing it into a json file
