There is lots of those locations that have AI traffic. But I hear your quest/intent Garry to try to be consistent and have your folders/files orderly and tidy! (I'm the same way!) Like something out of order well it is just wrong. Arg! and everything needs a proper place.
Right now am kicking this all around with this discussion as well as changing stuff for the testing work (eswitcher (in beta). There is lots of non-consistent stuff. Some AI traffic files in the scenery folders, others in the designated for scenery-world-scenery - files from other devs too that have NO desginated scenery folder to which they belong. Scenery folders themselves with weird names and not following correct order just weird in my mind as all has to be in order.
Really, the traffic.bgls files as well as the ADEX/ALT files (IE: ORBX, Aerosoft, etc and RTMM so far) placed all of these types of traffic or ade elevation files (bgls), in scenery-world-scenery - which is equivalent to layer 3 of the sims' scenery library.
Then in P3Dv4x concerning add-on scenery - the new methodology was to set up all the add-ons to be external to the sim in alternate folders - totally external to the root sim folders (set via scenery.cfg or other cfg files or via addon.xml files). IE: A separate Folder for AI Traffic files, or ALT-ADEX folders) or a parallel scenery-world-scenery folder and placed at layer 3 of the sim library- and those folders set up for the sim to see and execute.
Not sure whats best yet as to the placement of ai traffic files but in my pea brain, the scenery is the scenery location but the AI traffic files, although it may be close to that scenery, can run totally separate or independent to the scenery location so they shouldn't actually be in the scenery folder.
In my noggin' the AI traffic is tied to simobjects not the scenery loation: either airplanes or boats for the most part and the traffic files dictate to the sim when/location to show the airplanes or boats and what path.
Just like the AI ORBX or Aerosoft, AI Global Ship traffic - or ai traffic created by any other 3rd party designers - none of these ai traffic files are placed in the scenery folders but are located in an equivalent world type of folder - and placed at layer 3: again a parallel to the sim's scenery-world-scenery folder.
Now the AI Global ships package- has no scenery folder at all and is simply simobjects (Boats) and almost 1400 ai traffic files (bgl) to make it all the ships/boats run in the sim (when called). These ai traffic files are placed in scenery-world-scenery or an equivalent folder - at layer 3. (which is the layer for scenery-world-scenery). Do they need to be there? Or why should they be? Or where is the best place they should be ?
I honestly don't know but we must be consistent.
Currently in my system I run all AI (and ALT) files in separate scenery folders- external to the sim and external to the scenery pieces - and these are placed at the layer 3 level in the scenery library - Easy to setup - all AI traffic files for various 3rd party are in their own folders - turn off ALL or some or any separately and keep the rest still running- and no hunting for files in various scenery folders.
Also with the traffic bgls NOT in the scenery folder of a location, you can run ai traffic without the need of the scenery piece/location even being enabled and turn on those "Other folders" either using the scenery lib/cfg or add-on xml.
ALT/adex files in their own folder again are easily isolated -easily turned ON-OFF when required to isolate if there's an elevation issue or for testing etc.
Anyways playing with all this stuff too- (I have changed my entire setup in the last week- and am testing the locations of ai traffic files for functionality, user-ability as well as flexibility). And sure do want to be able to set up the folders/files from the zip files-fast and efficiently - and in the same folder zip/folder structure for fast copy/paste folders and with no guess work where stuff should go.
All to say, we definitely need this discussion for sure to hammer out consistency of scenery folders, it's contents, the proper/correct files placement in which folders for functionality and being able to maintain correct layering for the sim scenery and for the running of the add-on components and AI Traffic. The sims and recommended placements for addon folders/files seem to be changing and consistency is key for the user community.
All devs should be consistent if possible - which ever way might be the correct way to do this stuff these days? so us end users aren't totally confused and end up having files all over the place!! and the easier the setup the better!!
