[ThibaudPHP 8]

Hi, is there any update as to when the UDP data for ghost lap times is going to be patched?

There is no session UID in final classification header anymore. This way all our applications are useless.

 

{
m_packetFormat: 2020,
m_gameMajorVersion: 1,
m_gameMinorVersion: 7,
m_packetVersion: 1,
m_packetId: 8,
m_sessionUID: 0n,
m_sessionTime: 0,
m_frameIdentifier: 0,
m_playerCarIndex: 0,
m_secondaryPlayerCarIndex: 0
}

I just race the weekly event and noticed that when you use the multiplayer car, then your car number is the one you choose when you create your profile.
 

Still waiting to know if this behavior (F1 cars: real car numbers, even in online games when you race with your character / Multiplayer Cars: your chosen number) is the right one or is an error and is going to change back to previous versions behavior

With 1.07 we will have the avatar number, not the official one. I test on PC ;)

Still no FTLP and SPTP Events in Multiplayer.
Still wrong weather data in session package. Values like 10 and 8 instead of 0 to 5.

😫😥

I receive the SPTP when i am spectator. Never use the FTLP so i can't answer

Thanks for information. I will try some constellations, but slowly there is no hope anymore Codemasters will fix it.

Hi,

Does anyone know the meaning of the data in these fields ?

    int16         m_worldForwardDirX;         // World space forward X direction (normalised)
    int16         m_worldForwardDirY;         // World space forward Y direction (normalised)
    int16         m_worldForwardDirZ;         // World space forward Z direction (normalised)
    int16         m_worldRightDirX;           // World space right X direction (normalised)
    int16         m_worldRightDirY;           // World space right Y direction (normalised)
    int16         m_worldRightDirZ;           // World space right Z direction (normalised)

Thx ... Andy

 Could anyone give me some advise on how to calculate the gap between cars?

There are several ways depending on how often you want to update it, but you can use the session time in the header as a reference time and then compare something between the drivers (lap distance, sector etc)

hi! 

can anyone help me how I can get the data using python?

i'm trying to get it via socket, but i don't know where to absorb the data

tks

Hi!

After the new patch, the game shows some useful informations related to pit stops in the "Pit Stop" tab of the menu during the races.

Is there any way to get this info out (like we already do for other similar events) now that it has been added?

That would be really useful.

 

Thanks!

This might sound like a basic question but what is the expected range and unit of values for wheelSlip and wheelSpeed? I currently get values like 0.004381676 for wheelSlip and sometimes as low as -29 all the way to 97 for wheelSpeed and those values don't seem to make sense to me. I don't want to rule out that my code is just not decoding the data properly but without it being documented anywhere it is quite hard to tell what realistic values are.

On a side note: it would be super helpful if we could get the ranges and units for each field as well as an example "package" as part of the docs for reference.

Hey there i have a problem! I want to write a python tool for multiplayer sessions. i want to use the names of the players in the game. the problem is, that only the names of the real F1 drivers are appear. The other called everytime "Player" can i get the name on otherwise?

 

 

thanks for help!!

Sorry - we have not managed to get to this yet. Unfortunately, there are a couple of other issues that the team has had to look at. We will try and get to this as soon as we can.

@Hoo Are there plans to work on this UPD-issues? For me it is still important to have the correct penalties in seconds. 

 

And here are a lot of other problems written that could be fixed.

 

Kind regards,

Mark

Someone wrote a python tool here, maybe you can use this as an example.

This has been discussed multiple times already. Codemasters claim they can't send the username because of data protection rules (which is ridiculous). As a workaround I use "Player" and the Driver ID in the ParticipantsData packet.

I thought after two months there would be some updates here, but it looks like telemetry isn't important enough compared to all the other bugs that need fixing. Maybe there'll be some updates in F1 2021.

I have encountered a few issues with the telemetry data over the past few months which causes erroneous data to be displayed in my app (https://apps.apple.com/gb/app/race-engineer-2020/id1522782768):

Currently running v1.12 on PS4
1. During a session, if a driver pits, their `m_driverStatus` is stick at 2 (in lap) for the rest of the session

2. The visual and actual tire compounds for F2 and classic events seem to be wrong (or swapped around). For example, I am reading values of 22 and 14 for visual and actual respectively which currently out of bounds according to the telemetry spec. Also, in the spec, it is not clear what "Same as above" means. Are you referring to the same as the actual tyre compound? Or the same as the F1 tyre compound?

3. When a driver invalidates "this and the next lap", the `m_currentLapInvalid` value for the next lap is 0, but it should be 1

4. All event packets are sent twice

5.  The final classification data packets are sent twice
