Hello. This plugin doesn't translate languages automatically, you need to translate it manually. What the plugin does is to add more languages for your game players to choose from. The plugin makes the whole localization progress significantly easier and more time-saving thanks to its realtime ability and its ability to extract everything to a spread sheet file (including skills, items, equipments, maps, character names, etc.)
The plugin also supports translating as you play the game. The plugin will highlight what line is being spoken - this helps your translator can visualize the context of your game with super ease.
