gamePyd

Playing video games is fun isn't it? So why should making Python play games be any different ? It should at least be easy! surely ? That's what this library here is for. gamePyd provides readymade methods for common use cases. It also gives you the bricks it used as well, making reading and emulating xbox controllers trivial on Windows.

Under the hood, nefarius's ScpVBus is wrapped to interact with XInput, which is in turn wrapped in methods to let you work with your preffered data structure and seamlessly use the transformed information to control gamepads. Currently we support dataframes, lists and dictionaries.

Prerequisites

This library should work with anything after Python 3.6, albeit testing has only been done on 3.8.4 and later. Currently the only supported OS is Windows 10.

To use the Virtual Controller object, you need ScpVBus. For ease one of it's versions is included in this project. More information about the original can be found at nefarius's archived repo. You'll probably also require x360ce for easing the connection to games as well as debugging it. I've included it's older version as that's the one that worked for me.

Installing ScpVbus

We need ScpVBus to talk to Windows about gamepad related details: Open an elevated cmd command prompt in the ScpVBus-x64 directory and run devcon.exe install ScpVBus.inf Root\ScpVBus. Successful run is indicated by the following message:

Device node created. Install is complete when drivers are installed...
Updating drivers for Root\ScpVBus from {Location}\PYXInput\ScpVBus-x64\ScpVBus.inf.
Drivers installed successfully.

Installing

Now that the basics are done, we ought to go throught the usual motions:

Install via pip

pip install gamePyd

Are you in a rush?

Two main modules:

  • writePad contains object [wPad] which you use to control (upto 4) virtual game pads
    • use the playMoment method to assign a state passed in as a dictionary
    • or pass in a dataframe with rows as states to playback.
  • To read gamepads(virtual or physical), you use the rPad object in readPad
    • record will read the controller at a given rate for a fixed duration, and return a dataframe.
    • capture will do the same, but instead terminate only on detecting a specified button press on the controller.

If you're not in a rush, please head to the wiki pages. If you'd like to request any features please raise an issue.

Test the reading of controllers

Running test_read() should give (the output below was when no controller was plugged-in):

Testing controller in position 1:
This will just take a second. We'll look at the controller values in 200 milli-second intervals:

Better yet, you can use prettyRead() to sample as many times as desired for any required duration.
And then return it as a dataframe, can even write it to a file by supplying the filename.

Do note that the final three columns are metadata.

Roadmap

Salient upcoming features are listed below (more details in the accompanying project):

  • Calibration for machine-to-machine speed differences, so as to automatically minimize deviation from reading rate.
  • Check for lag while writing to gamepads
  • Add unit tests
  • Expand the wiki
  • Perfomance testing
