--- Component to wrap over GUI Text nodes with localization helpers
|
|
--
|
|
-- <b># Overview #</b>
|
|
--
|
|
-- • The initialization of druid.set_text_function is required to enable localization
|
|
-- using the localization ID.
|
|
--
|
|
-- • The LangText component supports up to 7 string format parameters.
|
|
-- This limitation exists due to certain issues with using ... arguments.
