Trackmania 2020 — DataSender Plugin Docs

A tiny guide for grabbing race + vehicle-state data over sockets.

OBS: Make sure that you enable the plugin in the openplanet settings as this plugin does not come with automatic sending turned on.

What this plugin does

Configuring

Open the General tab in the Openplanet overlay (F3):

Buttons: connect / reconnect / restart server + connect / disconnect / Reset to defaults – self-explanatory.

Quick-start receiver (Python)

# 1 Install deps (once)
pip install websockets

# 2 Run the dual-channel logger
python feed_server.py          # or  python feed_server.py --mode feed|vstate|both

When the plugin connects you'll see pretty-printed JSON dumps like:

{
  "map": "Stadium C-05",
  "gameTime": 123450,
  "cpCount": 12,
  "players": [
    {
      "name": "Zoop",
      "login": "zoop123",
      "raceRank": 1,
      "bestMs": 56234,
      "respawns": 0
    }
  ]
}

Vehicle snapshots contain fields such as spd, pos, rpm, slipFL, gear, etc. (see vstate.as for all fields).

Integrating into your project

• Replace the logging.info(...) lines in feed_server.py with whatever pipeline you need—DB insert, OSC forwarder, HTTP POST, etc etc etc
• Writing your own client? Any WebSocket library will do—just subscribe to /feed and/or /vstate and parse JSON.
• Remember to handle reconnects: the client in client.as will automatically try again every 3 s if the socket dies.
