Hey again,

I am testing out some alternate methods for some generation in my mod, and find myself needing a way to write nested arrays/hashmaps to NBTTags for use in the WorldSavedData extension I have created. In my case I am storing an integer array for specific world positions, so the array accessor would be data[X][Y][Z][], where the final array contains a list of the ordinals of my custom ores.

What is your problem? Are you having hard time implementing it?

You just need to nest NBTTagList, just like nested NBTTagCompound. Just use index instead of String key.

I was super tired when I posted that, nested NBTTagCompounds work just fine
