MOTION CAPTURE function
« on: September 22, 2023, 08:15:19 AM »

HELLO TO THE WHOLE COMMUNITY OF SAS

I WOULD LIKE TO SHARE WITH YOU AN IDEA CONCEIVED SOME TIME AGO, WHICH IN MY OPINION COULD GIVE NEW POTENTIAL TO IL2  .

AND AS THE ABOVE OBJECT SAYS CONCERNS TO CAPTURE THE MOVEMENT DATA  (and there's one for weapon firing data ext.ext..) OF AN  AIRCRAFT ,  AND THEN PLAY IT AS NORMAL MISSION ACTOR .


THIS IDEA COMES FROM OTHER SOURCES SUCH AS "FSX TOOLS",

https://flyawaysimulation.com/downloads/files/18881/fsx-recorder-module-v13

 WHERE YOU CAN RECORD ENTIRE FLIGHTS OF ONE OR MORE AIRCRAFT AND REPLICATE THEM IN MISSION (to simulate air traffic) , AND I FOUND THAT THERE IS A SAME FUNCTION ALSO IN ARMA2 (applied to vehicles and aircrafts).


https://forums.bohemia.net/forums/topic/97795-oa-unitcapture-unitplay-functions

FURTHERMORE , I NOTICED THAT IN IL2 THE RECORDING FILES . NTK OR NTRK,  IF OPENED ARE THE SAME AS (.mis) MISSION FILES and SO I TRIED AN EXPERIMENT.

OPENING A TRK FILE I NOTICED UNDER THE HEADING [$$$records] WHERE THE MOVEMENTS OF THE OBJECT ARE RECORDED. I TRIED TO RECORD AND TRYING TO REPLICATE   A MISSION (as example  emergency belly landing of a typhoon),  AND CHANGING FILE FROM TRK TO .mis .

I MADE A FEW ATTEMPTS..........

WILL I BE ON THE RIGHT TRACK?

 NOT BEING A PROGRAMMER,
 ALTHOUGH I STILL HAVE SOME ELEMENTARY KNOWLEDGE
 OF SQF or SQS routines.  THAT HOWEVER HONESTLY IN THIS
 CASE I WOULD NOT KNOW HOW TO APPLY.

THAT YOU CAN GIVE ME A LITTLE HAND ,   :-|
OR , OTHERWISE  More realistically
IF THERE IS A PROGRAMMER THAT READING THIS POST
WITH ALREADY THE SOLUTION IN HIS POCKET(HEAD), SHOULD BE EVEN BETTER ......   :P

THANKS !

No they're not.
By the way, capslock day is 22 October, you're a month ahead.


That, my dear, is the most relevant part.
In .trk files (which by the way are outdated, incomplete, don't resemble the full track, missing all sorts of things) all content is unencrypted, whereas .ntrk files act as encrypted archives.
A .trk file starts with the content of the .mis file belonging to the sortie that has been recorded, followed by movement data of the actors.
In an .ntrk file, the .mis file is one of the encoded parts, together with initial actor states, skins, and all the movement data, cut into 1MB chunks and encrypted internally once more.
Essentially, .ntrk files contain the same data as what would have been transferred between server and client in an online mission.

In order to bring life to your request/idea, you'd first need to forget about .trk files as they're crap, then fully decrypt an .ntrk file (NTRK Wizard is a good starting point, use the forums search function to get the tool), then find the relevant chunks, glue them together, decrypt them, and finally decipher the state and movement data for all actors.

Once that has been achieved, we can talk about altering data and re-encrypting / repacking it.
