f1_23_obs_overlay

This python app shows car data that are fetch from the F1® 23 game in a nice UI.

Installation

To install all the necessary libraries, you will need to use:

pip install -r requirements.txt

Library modification

For this script to work, you will need to modify the f1-23-telemetry python library. I know not idea but it is necessary ☹. After installing the library you will need to modify the listener.py file. To find the file run this command :

> pip show f1-23-telemetry
Name: f1-23-telemetry
Version: 0.1.4
Summary:

Author: Chris Hannam

Location: <PATH_To_LIB_FOLDER>\venv\lib\site-packages

Required-by:

You will find the path to the library in the Location field. the listener.py file will be inside the f1-23-telemetry folder and copy/paste this code.

"""
Basic listener to read the UDP packet and convert it to a known packet format.
"""

import socket
from typing import Optional

from f1_23_telemetry.packets import PacketHeader, HEADER_FIELD_TO_PACKET_TYPE


class TelemetryListener:
    def __init__(self, host: Optional[str] = None, port: Optional[int] = None, timeout: Optional[int] = None):
        # Set to default port used by the game in telemetry setup.
        if not port:
            port = 20777

        if not host:
            host = '0.0.0.0'

        self.socket = socket.socket(family=socket.AF_INET, type=socket.SOCK_DGRAM)
        self.socket.bind((host, port))

        # Set the listening timeout.
        if timeout is not None: 
            self.socket.settimeout(timeout)

    def get(self):
        try:
            packet = self.socket.recv(2048)
        
        except TimeoutError:
            return None
        
        header = PacketHeader.from_buffer_copy(packet)
        key = (header.packet_format, header.packet_version, header.packet_id)

        return HEADER_FIELD_TO_PACKET_TYPE[key].unpack(packet)

Execution

To start the program execute the main.py file.

Windows

python main.py

Tweaks

If you want to use this script without OBS, you can modify the config.py file to have a black background.

# OBS SETTINGS
IS_OBS_OVERLAY = 0
CHROMA_KEY_COLOR = (180, 0, 255)

Setting the IS_OBS_OVERLAY to 0 will set the background to black whereas setting it to 1 will set it the the color from the CHROMA_KEY_COLOR variable.
