Using ScriptHook V / ScriptHook V Dot Net and some C++ / C# / VB.NET knowledge, you can actually make a script that, on a button press, modifies the vehicle speed to a desired value.

Also, i think the MaxFlatVel is not the good value for the speed limit.

I looked around in the Vanillaworks Server, and i found the solution.
It's actually (trackid) + "S" for the song name, and (trackid) + "A" for the author.

Example : For track id 9520
9520A : AUTHOR OF SONG
9520S : Name of the song

@jamesays Thanks for your help anyways.

EDIT : The solution came from one of Wildbrick's messages, the creator of the Community HUD.

@jamesays said in Need help with track ids:

i dunno maybe the name of the audio file.

it could be but the author and the song title are two different hashes so

@jamesays I already have one (i use openiv) but what names are you supposed to enter in it ?

btw i know it's a language file like global.gxt2 but i'm stuck for the hashes. For each songs, there is an author localized string (ex : "BATTLE TAPES") and a song title one (ex : "Feel The Same"). How are you supposed to get these hashes ?

I'm kind of new to GTA V modding. I've made some radio stations and i know how to assign them track ids but i don't know anything about the trackid.gxt2 file.

Any clues ?
