Hi, I'm creating a custom mod for my server, because the use of KCauldron for plugin functionality seems to break a lot of things. Anyways, I'm currently working on a module for creating and managing sky islands for my skyfactory server. I have a command for people to create islands, but once the island is created, I want to somehow save the name of the island and it's coordinates so I can access it later. I considered storing it in player NBT data, but then the islands would have to be assigned to players and they would need to be online. I suppose I could also save it to the world's NBT data, but then if a player is in a different world and tries to access it, there may be problems. How can I save the data so that I can access it later?

Simply save it to file using standard IO operations.

 

If you want to utilize NBT use CompressedStreamTools.

 

Coords can be saved server-wise (not per-world) in some static class/map/list.
