翻訳ファイルサンプル
AndroidでStreamingAssetsが取得できなかったので、Resourcesに入れた。
Assets/Resources/Localization/localizedText_ja.json
{
"items":[
{"key":"title","value":"タイトル1"},
{"key":"edit","value":"編集1"}
]
}
Assets/Resources/Localization//localizedText_en.json
{
"items":[
{"key":"title","value":"title1"},
{"key":"edit","value":"edit1"}
]
}
上記DLしたファイル設定とカスタマイズ

設置方法
- 起動sceneに適当に空のGameObjectを作る
- そこにLocalizationManagerとStartupManagerを貼り付ける
- 翻訳したいTextオブジェクトにAddComponentsでLocalizedTextを選択しKeyにjsonのkeyに指定したtitle1などと入れる。
無事翻訳できた。
手動で切り替え
手動でやりたい場合は以下のようにすると良い。
LocalizationManager.instance.LoadLanguage("ja");
Androidのアプリタイトルの多言語化
Assets/Plugins/Android/res/values-ja/strings.xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="app_name">タイトル1</string>
</resources>
Androidの場合は読み込めない
StreamingAssetsではAndroidの場合は読み込めないのでResourcesに移動してある
