Sword and Fairy 7 Translator is a tool that automatically extracts english, chinese (simplified) and chinese (traditional) texts from the game files and allows you to change it as you like.
It also comes with two translation APIs (Microsoft Azure and DeepL), so you don't have to look anywhere or do translations yourself by hand.
Simply run the program, fill the configuration form and let it do all the translation for you.
In order to benefit from the automatic translations you need either a Microsoft Azure Subscription with a Translator service enabled, or a DeepL api key.
Both of these can be obtained for free.
For any translation purpose, I suggest you first run the app with a microsoft azure subscription, because there are about 1.9 million characters to translate to whole game, and microsoft azure has a monthly limit of 2 million characters (if you exceed this monthly quota, you have to pay).
The free DeepL api key has a 500k characters monthly limit.
Once you obtained that first translation, I suggest you to switch to DeepL to do your reviews, as DeepL translations are better than those of Azure (in my opinion).
How to install and use :
Simply extract the zip in a directory of your choice (*) and run SwordAndFairy7Translator.exe.
(*): the full path to SwordAndFairy7.exe must not be too long, otherwise UnrealPakTool will have issues repacking your mod.
So put it somewhere like : X:\Modding\SwordAndFairy7Translator...
Avoid things like : X:\verylooooooooooooooooooooonnngpath\longerthanthenileandamazonrivercombined\addalsothedistancetothemoonjustobesure...
How to change the in-game font :
The app will create a directory Pal7\Content\UI\font\ in its installation directory.
So, if you extracted the zip in X:\Modding\SwordAndFairy7Translator, you'll get a X:\Modding\SwordAndFairy7Translator\Pal7 directory.
In that directory there is a file : X:\Modding\SwordAndFairy7Translator\Pal7\Content\UI\font\FZBWKSJW.ufont
This is actually a true type font (TTF file) whose extension has been renamed to ufont (for unreal font).
Simply choose another true type font of your liking and replace this file before hitting the button Pak.
