Speed Dreams Community

Hi,

I am trying to find a way to record user data in Speed Dreams. With this I mean the user inputs (accelerator position, brake pedal position, steering angle,...) as well as the users car position (current track segment, exact track position, speed, de/acceleration, direction,...). Ideally I am trying to achieve something that outputs a text file for every completed lap but any other output would be great as well.

Is this possible in Speed Dreams or any other racing simulation for that matter? Is it possible to record similar data for AI drivers?

Any pointers would be greatly appreciated.

There was some discussion on the mailing list regarding 'telemetry', which looks to be what you're asking for:

Don't know the current state of things, perhaps another dev can confirm.

You don't say which platform you are on; it's been mentioned that the 'Telemetry module' only supports linux, although I might be wrong as I have never tried using it....

Hi All

Has there been any progress made on this issue? I would very much like to use the SD simulator for a project I am currently working on. We will need SD to output telemetry and gps data, has this feature been added to the simulator?

I don't believe that anyone did any work on that, but we're happy for any contributions of code.

BTW you may be interested in the 'replay' functionality which I've been working on. This saves the state/position/etc of each car out to a SQLite database, and allows it to be replayed later. It's not in the main tree, but we'll probably included it after the next release.


You might be able to use the resultant SQLite DB, or modify the code for your specific needs.
Cheers,
Simon.

I was hoping this was going to be a little easier. OK so now I have to ask, do you know of any other open source racing simulators out there which do offer this feature? I'm not sure why you guys don't offer it, maybe its a resources thing, but it would make the simulator a lot more useful to engineers, and embedded programmers in the robotics and automotive fields.

Yes you are probably right, I'll give this some thought, I would really like to use the Simulator. I'd even be interested in paying someone to write the patch for me, I have a ton of work on my hands now, adding this to the stack wouldn't be good.
