Documentation

Overview

Package chat implements Minecraft's chat message encoding system.

The type Message is the Minecraft chat message. Can be encoded as JSON or net/packet.Field .

It's very recommended that use SetLanguage before using Message.String or Message.ClearString, or the `github.com/SkyVillageMC/go-mc/data/en-us` will be used. Note: The package of data/lang/... will SetLanguage on theirs init() so you don't need to call by your self.

Some of these docs is copied from https://wiki.vg/Chat.
