Support for different languages.

[Mr-RainC0at]

I am currently adding a few custom items to a Fabric Server I run with my friends, who are Korean. I would like to know if it is possible to have items have translated names for certain languages like the base game of Minecraft.

Yes, however the displayName method on items/blocks will only generate for U.S. English (because of this line)
To generate for another language you need a client script in the kubejs/client_scripts folder of your friends modpacks that looks like this:

// this requires minecraft 1.19.2+
// older versions use a different event that only supports U.S. English
ClientEvents.lang('ko_kr', event => {
  event.renameItem('kubejs:some_custom_item', "Sorry, I don't know any Korean")
  event.renameItem('kubejs:other_item', "Still don't know")
})

Where ko_kr is the language identifier (there is a list on the minecraft.wiki) and the rest is pretty self explanatory.
