World Data Loader

This mod enables the loading of pre-prepared data files directly into Minecraft game worlds. It works equally well with both other modifications and datapacks.

To start using it, you need to place your data files in a special directory: data.<namespace>.world.<dimension>

It's important to note that the namespace parameter refers to the dimension's namespace, not your mod's or datapack's.

As a practical example, consider loading pre-generated maps into your world. To test the functionality with a datapack, use the command: /give @s minecraft:filled_map{map:30204}
