Is it intentional that you lose the saved EntityData when a player dies? Its kind of annoying, especially because I found that out after coding 2 mods that use it as a permanent player-tied data storage.

To bypass that I assume I need to write my own data storage system? (It will probably use a username.dat, just in a different folder  :'()

If this is the case

If this is the case, you could make it store in the mods folder, again within its own folder. Like... /Example Server Folder/mods/SimpleServerData. I know that doesn't help much in terms of what you're expecting, so I'll shush. 

I'm going to integrate the player tied system in SimperPermissions so all the mods that use permissions can set player-tied data, that way I only need to code it once, and not for every mod ;-).

 

I found out after wanting to /home after I tried swimming in lava 

 

I'm gonna store it in the folder SP uses for it's config and ranks and permissions. I might even 'Upgrade' the permission/rank files to .dat files (I finally found out how MC stores them)

Entity data is tied to an entity, the player controls an entity, but is not an entity itself, and its entity does indeed die.  You can use global save NBT's to store, or a custom file, however. 

I just made .dat files, they use the same save/load system as Minecraft.

I like the NBT system a lot. There is just one thing, Is it me or is it impossible to remove tags?

Never tried.  Can always reflectively do it in the worst case.

I found out you can best store a collection (with .getTags()) and then run that through a while(Iterator.hasnext()) loop and kill out the ones you don't want.
