F1Sharp 1.0.1

F1Sharp

Receive and parse the telemetry packets from the F1® 23 game, and hopefully future ones too.

Current UDP specification can be found here.

Since the specification changed from last year's game, this library is only compatible with F1® 23 for the moment.

Usage

Enabling telemetry

UDP telemetry must be turned on in your game for this library to work. You can find the telemetry settings in Options > Settings > Telemetry Settings (F1® 23).

By default the UDP Telemetry option it's off, so you have to turn it on. While you're here you can also change the UDP Port setting if needed. The default is 20777.

Instancing client

For receiving the events you have to create an instance of TelemetryClient.

// Instance the client listening on port 20777 (the default)
TelemetryClient client = new TelemetryClient(20777);

This instance has events that you can hook into for managing the data updates coming from the game.

// Hook a method to the OnCarTelemetryDataReceive event
// This event represents whenever a packet is received that involves car telemetry (current speed, throttle or brake applied, engine RPM, etc.)
client.OnCarTelemetryDataReceive += Client_OnCarTelemetryDataReceive;

private void Client_OnCarTelemetryDataReceive(CarTelemetryPacket packet)
{
	// Get the player index from the list of cars in the session
	int playerIndex = packet.header.playerCarIndex;

	// Select the player's car from the list of car telemetries
	CarTelemetryData carTelemetryData = packet.carTelemetryData[playerIndex];

	// Write to console the engine RPM
	Console.WriteLine($"Engine RPM: {carTelemetryData.engineRPM}");
}

Data binding

I included ViewModels for a few of the data types for making it easier to use in GUI projects (I'm doing one of my own 😉). I'll add a few more if my project gets more interesting and requires more ViewModels.

The ones included for now are:

• Car Damage
• Car Setup
• Car Status
• Car Telemetry

Aknowledgements

Thanks a lot to @thomz for coding the library that inspired this one.
