How to save special mod data about a player

[Elena_the_Puppy]

I believe the proper way to do this is through capabilities, but i'm not certain, and would love any advice.

It depends on the data you want to save, but generally speaking you should use some custom Player Capabilities, attach to the Player and use them to store/retrieve any kind of data you want.

You can find how to make them work for 1.20.x in the documentation here: https://docs.minecraftforge.net/en/latest/datastorage/capabilities/
