Changing language does not update text from script

There is no built-in approach to relocalize any text you are managing by code. At then end, to make it work, that code has to run again.

The easiest way I see, it's by adding your methods to the global LocalizationManager.OnLocalizeEvent. That way they get called whenever a language is changed.

However, the best solution its to add Localize components to each of those texts. Then instead of modifying the text directly from your code, call localize.SetTerm instead.

That way, you will still have control in your scripts over the translations, but given that the Localize component knows the term you are localizing, then anytime the language changes, it will automatically change the text to the correct language.

If you need to have control of the translations in code because you are adding numbers and other parameters, then you could change the code to use Translation Callbacks for modifying the translation. That will still keep everything managed by the Localize component.

Hope that helps,
