I am currently writing my first mod, and having a blast doing so, but I have a question I am hoping one of you kind folk might be able to help me out with.

 

I am quite familiar with NBT and saving data against items, but I am reaching a point where I need to start saving data about the world itself, not relating to any given item or entity.

 

Now I could obviously just use standard I/O libraries to serialize the data to disk (and read on load), but I am assuming there are cleaner more standard ways to handle data within the Minecraft/Forge framework.

 

As an example of the type of data I would like to store:

 

• I generate dungeons, and would like to maintain a list of known dungeon coordinates so that I can tightly control the distribution and progression of the dungeons.
  
• I also plan to introduce boss monsters, and would like to store a "last killed" time to prevent over farming.
  
• I would also like to introduce various world "achievements" where if anyone on a server completes a certain task, it unlocks new adventures for everyone on the server. So I need to store which tasks have been completed.
  

 

Hope this makes sense. I don't need specifics on how to pull of each of the listed items, just a general guideline on how best to store world-level data.

Thank you very much for the response and the example

So when is writeToNBT getting called? I would expect it to be when the game gets safed to disk, but I got a sysout that is never shown sadly

loading and saving is manual - look at static method at end of file in example (Questology).

nvm forgot to call setDirty.
