[1.12] Uniquely identify a world

[Socratic_Phoenix]

When storing information during, how can I uniquely identify a world? 

 

Some context:

I am rewriting my mod which previously used the world seed (I know, terrible), but obviously more than one world with the same seed can exist. I was also previously storing information in a Map<Seed, MyObjects> which is also pretty terrible. So:

1. What can I use to uniquely identify a world?
2. Is there a better way than using a Map?
3. Is there any easy way to sync data between world & client?
4. Is there any easy way to allow the data to be fully configurable?

By "world", do you mean a World object (i.e. a dimension), the map/saved game as a whole, or something else?

A single save (overworld, nether, & end)

Is this data only used by the save it's attached to, or do you need to access the data of other saves?

I shouldn't have to, no...

 

I've been doing some research, is WorldSavedData what I'm looking for? I need to be able to access the data client side, and the data needs to be synced... will I have to do that manually?

 

Edit:

Hmm... WorldSaveData doesn't appear to be what I want... Is there some unique id I can use? Such as a UUID or maybe the save dir name?

World Saved Data should be what you need. It can be attached per-dimension or per-save. Each side has its own copy of the data, syncing needs to be done manually.
