AssetBundles and PDFs are mistakenly downloaded/backed up as models

[bobpaul]

Mods consist of folders Workshop, AssetBundles, Images, Models, PDFs,

• PDFs should go in the PDF folder with a .PDF extension.
• AssetBundles should go in the AssetBundles folder with the .unity3d extension.

---

Along with that, currently assets are identified as Images or Not-Images based on the file extension. JSON is a structured document. The file type can be determined from parsing the JSON file itself. Additionally to the sections they're in, each type has a unique FooURL keyname:

AssetbundleSecondaryURL - AssetBundles
AssetbundleURL - AssetBundles
BackURL - Images
ColliderURL - Models
CurrentAudioURL - N/A, Don't Download
DiffuseURL - Images
FaceURL - Images
ImageSecondaryURL - Images
ImageURL - Images
LutURL - Models? it's a Lookup Table, not sure what the format is :-/
MeshURL - Models
NormalURL - Images
PageURL - (Inside the subkey of Tablet) - don't download, can be anything that displays in a browser.
PDFUrl - (inside CustomPDF) - PDFs
SkyURL - Images
TableURL - Images
URL - inside `CustomUIAssets[]` - Images

https://kb.tabletopsimulator.com/custom-content/save-file-format/ has most defined, but doesn't include Page or PDF

Here's jq queries for each of the URLs. This exposes the structure. Ex: Get cat FOO.json | jq '.TableURL' to grab the table URL.

AssetbundleURL, AssetbundleSecondaryURL
'.ObjectStates[] | select(.ContainedObjects != null) | .ContainedObjects[] | select(.CustomAssetbundle != null) | select(.CustomAssetbundle != null) | .CustomAssetbundle | .AssetbundleURL, .AssetbundleSecondaryURL'
'.ObjectStates[] | select(.CustomAssetbundle != null) | select(.CustomAssetbundle != null) | .CustomAssetbundle | .AssetbundleURL, .AssetbundleSecondaryURL'
'.ObjectStates[] | select(.States) |.States[] |select(.CustomAssetbundle != null) | select(.CustomAssetbundle != null) | .CustomAssetbundle | .AssetbundleURL, .AssetbundleSecondaryURL'

BackURL, FaceURL
'.ObjectStates[] | select(.ContainedObjects != null) | .ContainedObjects[] | select(.CustomDeck != null) | select(.CustomDeck != null) | .CustomDeck[] | .FaceURL, .BackURL'
'.ObjectStates[] | select(.CustomDeck != null) | .CustomDeck[] | .FaceURL, .BackURL'

Yeah, the format has moved on a lot since I last looked at this. This is useful information though, thanks.

So I have a ttsmod branch in my fork where I introduced a Mod class (currently in the save.py file). My idea is that the Mod class will represent the Mod/Save/Chest whether fed from a zip file or a files on disk. It does introduce an opportunity for a major refactor that I've only partially started... but I'm not 100% sure I'm sold on it.

Right now it's just sort of pigeon holed in. I think I see it replacing most/all of the Save class and simplifying Filesystem. The Mod class tracks the relative paths common between the filesystem and the zip.

My goal is to use that for #27, #33, and #28. As it stands, it does implement #28 and fixes #33 at least partially. For #33 I'd like to make it import PDFs and AssetBundles from the old .pak files that were storing them in the Models folder, but I haven't gotten that far and it might be a few weeks before I get back to this.

So, I ended up implementing this yesterday, as I realised it was pretty much required for #27, by basically adding a FileType enum and deferring the decisions on what something is and where it is going to go to to that.

I'm not entirely sure what the distinction between a Mod and the existing Save class would be - there is a decent argument to rename Save to Mod - the track of where the files map to is kinda mostly in the (also now badly named Url class) - There definitely needs to be a bit of a refactoring.

Importing from old ones is a good point, I'll add a new issue for it.
