So i have a configuration file where you can set item's lore like this: Code: lore-overrides: - id: 1 lore: "Hello world" - id: 2 lore: "this is test lore message" And a command that writes lore to item using ItemMeta and sets "custom_lore_id" nbt tag. Now, how do i globally update item's lore when configuration values change? Every item that has custom lore has "custom_lore_id": <number> NBT. There is a HashMap<Integer, String> of these ids mapped to lore messages. I've thought about modifying outgoing packets and setting item's lore there instead of using ItemMeta, but not sure on how do i modify packets. I have also thought about overriding CraftMetaItem#getLore method but CraftMetaItem is private class and i cannot override it. So i would like to know: is it really possible & worth it to modify packets? are package-private classes really not override'able? maybe other hints on how do i implement this?
