Support for nested folders

[NiklasEi]

I added a note in the readme about the recursive behaviour of loading a folder, thanks for pointing that out.

Keeping a path map for files in directories is also something I would see in the engine. This kind of behaviour also depends on your environment (e.g. usually non of this works in the browser) and should be baked into Bevy's AssetServer in my opinion. Maybe you want to file an issue on the engine repo for this? Once Bevy can do this, I would definitely add support here.

Under the hood, bevy_asset_loader is just using Bevy's load_folder here, which already is recursive. Your example should work without any new attribute needed. Does it not work for you?

Filtering for specific types is something I would see in the engine, not in this plugin. Possible APIs in Bevy have been discussed before (see e.g. bevyengine/bevy#2292).

Ah! I wasn't aware of the resistivity of folder loading! Perhaps it's me being blind or maybe this could be made clearer in the docs ?

Maybe it would be worth changing:

You can load all assets in a folder and keep them in an AssetCollection as a vector of untyped handles.

to:

You can recursively load all assets in a folder and keep them in an AssetCollection as a vector of untyped handles.

That's brilliant!

I guess this is also highly coupled to bevy's asset loader but would it be possible to support populating a mapping from relative paths to the handles instead of a simple Vec ?

This would likely involve searching the directory tree manually and then loading each asset individually (i.e. bypassing the load_folder, method), not sure if that's something you'd consider, but It would definitely be useful. One use case I can think of is storing prefabs under folders and linking their corresponding assets based on the path.

No worries,

Yeah that sounds very reasonable, I will go ahead and file an issue.

Thanks!

I see an issue for something like this already exists, I will link it here:
