NOTE: This guide is for Patch 1.1 which is currently in Beta

Download this file: english_text_sheet[docs.google.com]
(this file will be updated with every release that adds new text, I'll add new things to the bottom so it's easier to keep track of)

At the top of column C put the locale of the language you want to add.
A list of all supported locale codes can be found here: https://docs.godotengine.org/en/stable/tutorials/i18n/locales.html

Then in every row beneath write a translation of the entry to the left.

Anytime you see '%s' in the text, you must include that in your translation or the game will crash when it tries to display it. The %s is replaced in code with numbers typically (e.g. "+%s revolver bullets" becomes "+3 revolver bullets")

Subtitles are kept as json strings, you can edit these to make the text display better for your language. The number is the time in the audio file that text will display. You can add more entries to the array as well.

When done with your translation, export as a csv

Open Endoparasitic
At the bottom right click the 'Change Language' Button

You will see this screen:

Click 'Add Custom Translation' > 'Choose Translation File' and then locate your csv file and open it.

Translations may require a custom font as well to work properly, the default Endoparasitic font does not support non-English alphabets. To load a custom font click 'Add Custom Font' > 'Choose Font File' and then locate your ttf font file and open it.
