@yagejs-addons/i18n

Localization for YAGE: msg(key, fallback, values?) message descriptors, an i18next-backed Localization service, a plugin that re-resolves every localized text when the language changes, and one localized class per engine text surface — renderer text, imperative UI, React UI, dialogue, and the inventory panel. Switch language mid-line and the text swaps in place; nothing replays.

npm install @yagejs-addons/i18n

Subpaths keep the root free of pixi and React: ., ./renderer, ./ui, ./ui-react, ./inventory.

import { Transform } from "@yagejs/core";
import {
  createLocalization,
  LocalizationPlugin,
  msg,
} from "@yagejs-addons/i18n";
import { LocalizedTextComponent } from "@yagejs-addons/i18n/renderer";

const localization = await createLocalization({
  locale: "en",
  fallbackLocale: "en",
  catalogs: { en: { "hud.hp": "HP {hp}" }, it: { "hud.hp": "PV {hp}" } },
});
engine.use(new LocalizationPlugin(localization));

const hud = scene.spawn("hud");
hud.add(new Transform());
hud.add(
  new LocalizedTextComponent({ message: msg("hud.hp", "HP {hp}", { hp: 55 }) }),
);
localization.setLocale("it");
