Messages & localisation

All player-facing text lives in messages.yml, so server owners can reword or translate it without touching the jar.

plugins/ProjectOne/messages.yml

prefix: '<gray>[<aqua>ProjectOne<gray>]<reset> '

no-permission: '<red>You do not have permission to do that.'
player-not-found: '<red>No player named <yellow><player><red> is online.'
reloaded: '<green>Configuration reloaded in <ms>ms.'

Formatting

Messages use MiniMessage tags such as <red> and <bold>, not the legacy &c codes.

Legacy codes still work for now but are deprecated — say clearly which your plugin accepts, because mixing the two is a common source of "why is my colour literal text" reports.

Placeholders in messages

Placeholder	Replaced with
<player>	The relevant player's name
<ms>	Elapsed time in milliseconds
<prefix>	The prefix value from this file

These are message placeholders, filled in by the plugin. PlaceholderAPI placeholders that other plugins can read from this one are documented under Placeholders — worth keeping the two clearly apart, since the names collide constantly.

Translating

Copy messages.yml, translate the values, keep the keys. Do not translate keys or placeholder names.
