i have a question... Where can I find information about the grip level or how wet the track is or the equivalent of this stamp @Hoo:

The weather information is in the Session packet in the m_weather field and then m_trackTemperature and m_airTemperature. The m_weatherForecastSamples field would give you the forecast for the session.

This may help for F2 tyres: https://gitlab.com/gparent/f1-2020-telemetry/-/commit/6063dd6dc3b82743ab8597f58d09493117750590

Keep in mind the visual and actual tyres are different values.

Were the values for the F2 2020 teams documented somewhere or did you just take them from actual data? I couldn't find them in the previous post(s) https://gitlab.com/gparent/f1-2020-telemetry/-/commit/f7984f0ffe9667374e8fae9dd3a4957bdd998665

No worries. Once I have some free time I'll make a release with the F2 2020 changes. I'm missing driver IDs at the moment. I have the team ones.

Legend! I just wish this wouldn't be left up to us developers to figure out in the future 😞

Exucuse me.
If you use flashback, how do you delete the disabled packets?
Should I use the session timestamp(PacketHeader.m_sessionTime) in the header to make the decision?

[LonelyRacer 11]

Luckily my tool has  automated detection for ids/data not seen earlier.

Here are the F2 2020 new drivers + new teams detected. These are from the Enums, my tool uses. TLA is automatically created, but should be correct.

Drivers (I did edit the names, as the game only gives family name for these drivers). Format is (name, TLA, IDinGame)

DanTicktum("Dan Ticktum", "TIC", 91),
MarcusArmstrong("Marcus Armstrong", "ARM", 92),
ChristianLundgaard("Christian Lundgaard", "LUN", 93),
YukiTsunoda("Yuki Tsunoda", "TSU", 94),
JehanDaruvala("Jehan Daruvala", "DAR", 95),
GuilhermeSamaia("Guilhrme Samaia", "SAM", 96),
PedroPiquet("Pedro Piquet", "PIQ", 97),
FelipeDrugovich("Felipe Drugovich", "DRU", 98),
RobertShwartzman("Robert Shwartzman", "SHW", 99),
RoyNissany("Roy Nissany", "NIS", 100),
MarinoSato("Marino Sato", "SAT", 101),

F2 2020 Teams (took team names from the Race Director). Format is (IDinGame, Year, Long name, short name, Color Used e.g. in Map)

F2_2020_ART(70, 2020, "ART Grand Prix", "Art 2020", Color.GRAY), // ART
F2_2020_CAMPOS(71, 2020, "Campos Racing", "Campos 2020", Color.ORANGE), // Campos
F2_2020_CARLIN(72, 2020, "Carlin", "Carlin 2020", Color.BLUE), //Carlin
F2_2020_CHAROUZ(73, 2020, "Charouz Racing System", "Charouz 2020", Color.DARKBLUE), // Charouz
F2_2020_DAMS(74, 2020, "DAMS", "DAMS 2020", Color.CYAN), // DAMS // light blue?
F2_2020_UNI(75, 2020, "UNI-Virtuosi Racing", "UNI 2020", Color.YELLOW), // Uni virtu
F2_2020_MP(76, 2020, "MP Motorsport", "MP 2020", Color.DARKRED), // MP Motorsport
F2_2020_PREMA(77, 2020, "Prema Racing", "Prema 2020", Color.RED), // Prema
F2_2020_TRIDENT(78, 2020, "Trident", "Trident 2020", Color.BLUE), // Trident
F2_2020_BWT(79, 2020, "BWT HWA RACELAB", "BWT 2020", Color.PINK), // BWT
F2_2020_HITECH(80, 2020, "Hitech Grand Prix", "Hitech 2020", Color.LIGHTGRAY), // Hitech

If here are any errors, let me know.

Cheers

I would like to thank all the developers of the F1 2020 game for making it even more unplayable and bug-ridden to the point of no longer being able to race without seeing cars going wrong or disappearing and reappearing from one point of the track to another! All this after the F2 2020 update. Thank you so much because we all understood that we threw our MONEY to the wind!
We are a group that organizes, indeed, organized Formula 1 championships but now after yet another bad figure we have decided to totally change the type of game !! You only think about your profits and instead of improving things you make them worse and you don't care about the feedback from the end customer! I'm sure I won't be the only one complaining, as my group of 200 and I represent perhaps 1% of everyone who uses the game! But to complain even a professional Formula 1 driver means that there is some problem, but you are only interested in selling and earning !!
I hope that someone reads this post and that you solve all the problems that are there shortly because I, like other 1000 people, at least in Italy, will certainly not buy F1 2021.
Best regards

That appears to be off-topic here.

I know this has been widely debated here, but wouldn't it be possible to receive at least one unique id per gametag, encoded or as codemasters consider that it doesn't put the privacy of the players at risk.

If anyone can broadcast the list of gamertags to the entire world on twich, what is the problem with a person receiving it on a device at home?

Thanks

Hello. Is there any further definition of the telemetry attributes below?

In other words, the importance of the measurement(s) or the receipt of measurements combining?

 

struct CarMotionData

{

    float         m_worldPositionX;           // World space X position

    float         m_worldPositionY;           // World space Y position

};

    CarMotionData   m_carMotionData[22];    // Data for all cars on track

 

    // Extra player car ONLY data

Is anyone else seeing discrepancies with: 

float       m_fuelInTank; 

For me, the data received always seems higher than the actual value, eg 6.0 in the tank (and displayed in-game) comes through as 8.8 in the data. I'm on PS4. Thanks.

Did @Hoo left Codemasters? He doesnt reply to anything anymore

I have not seen the discrepancy. Are you sure you are getting data from the right car?

cheers.

Thanks, that's a fair question, but yes, I'm looking at the correct car (I did just re-check this when you asked!). Interestingly, none of the 22 sets of car data are showing the same amount of fuel as the in-game dash so I'm not sure what's going on at all.

Hmm, interesting. I would check, all other data received is correct in the CarStatus per car, fuelMix, e.g. m_drsAllowed & m_tyreCompound and other data?

Yeah everything else seems correct so I’m looking at the right player. I’m seeing this in the solo Grand Prix mode (not tested others). I’m on PS4, are you on PS4 as well?

I am on PC, latest Steam version 1.15. I see correct values. Tested with single race, set fuel to 29.0L and got the same value from the game.

I also noticed, if you do one-shot-quali, the game automatically adjusts your fuel load, i.e. you cannot set it yourself in the car settings.

Cheers.

I can't remember if the game lets you change the display units for fuel in game but are you aware that m_fuelInTank is in kilograms not litres?

I’ve only tested this (since the issue was raised) in game modes where the game sets the fuel level for you automatically, and that’s where I get the difference, perhaps this is where the bug is in the game.

I did look for units for fuel but couldn’t find anything in the game. Yeah, I’m aware it’s in KG so I’m just showing the number on the dash direct from the feed - there’s no conversion required as far as I can tell...

Thanks

The in game wheel displays how many laps of fuel not kg.
