Extract AI pit/fast lanes

[andrea_serafini]

Hi all, I was wondering if it's possible to get the fast lane's coordinates, throttle and brake data. I think it would be possible by unpacking the fast_lane.ai file, but i don't know how. Any suggests?

Thanks

this app reads in fast_lane.ai, in "def Initialize()"
4*4bytes header, second value is count of ai line points, then data

Thanks, exactly what I was searching for. Is there any place where i can find info about the data details structure created in the Initialize() method of that plugin?

i added some comments, maybe it makes more sense now
(note: he does not read all data available)

Ok, I got that, I was asking if someone can tell me what those 18 floats are.
Example -> I know that in data ideal the 4 floats ale x,y,z,point of track and sequential number of data segment. I was searching for information on data detail segment.

Thanks for the reply

in cm sources is some ai line stuff, this folder has some info https://github.com/gro-ove/actools/tree/master/AcTools/AiFile

Thanks, as i found implementing my script, not all the tracks seem to have the same packet structure. I found that custom maps or maps where i modified the AI with the app AI_line_helper have a packet structure, other maps have another structure. Does anyone know something about this difference?

not sure, i think in 'later' or newer ac versions - the format if those files changed to include more info, and they just appended that extra data to the old 'formatted' data to be compatible (con-cat'ed - so kunos'd )

So file/data size also depends on ac-verson that saved it. If you don't find enough data in the file with according to new format, then its an ai-line saved with old ac.
