Lang File Instructions

The language file (lang for short) is a file from which all text is referenced in-game. This can be freely edited by the player.

Editing the lang is actually a simple process:

1. Locate your folder for Nuclear Throne. On Steam this is by default located at 'C:\Program Files (x86)\Steam\steamapps\common\Nuclear Throne'
2. There will be a file called 'lang-example', which is the template. Make a copy and rename it to just 'lang'.
• If the lang-example is missing, it's also included when installing NTT.
• If file extensions are showing, this will be saved as 'lang.ini'. If file extensions are off, then just having it saved as 'lang' is fine.
3. The lang file can be opened with any text editor program, such as Notepad, to be edited. The sections below will further detail specific editing.
4. Once saved, any changes will be seen in-game the next time it is launched. Be sure to create a backup of the game files to not lose your work.

Localization support: There are a few fan-made translations that can be used in NT by simply placing it within your games folder.

For NTT usage: Running the command '/loadloc lang' will load the lang file into that session. If you want the lang to load every time the game is launched create a file called 'startup.txt.' in the mods folder. Write in this folder the same command you would use in-game, being '/loadloc lang', and save.

Lang File Editing

The lang file is split up into categories, with each category name in brackets. While anything in the lang file can be edited, only edit things AFTER the = (equal sign) on any line, as this is all the text that actually appears in game - everything before the equal sign is classification which directs the game on when to display that text.

Additional lines for screen tips can only be added in the 2023 beta forwards, which should include v100. In older versions the game will simply not register extra lines. To add more tips simply make a line break, copy the line from above and paste it onto the new line, increasing the tip number on it by one.

The font used in-game is the 'Press Start' font, though likely a modified version. This is a font that only supports base ASCII characters, so any text edits using other unicode will not appear in-game. Only 'Press Start 2P' font supports other unicode which is used in fan projects, but not within NT itself.

Text can be highlighted with a few colors. Use @ then a letter from the list below to signify what color it should be. @s is used to end the highlight there - though what it's actually doing is resetting the color to the default, being Silver. Multiple colors can be used within the same line.

• @s for the color silver (default color)
• @d for the color dark gray
• @w for the color white
• @r for the color red
• @b for the color blue
• @g for the color green
• @y for the color yellow
• @p for the color purple

There are a few other non-color effects which can also be used. These may not function in every part of text editing, but definitely will for loading screen tips.

• @q will make text shaky, it is used for cursed weapon screen tips. Putting @q repeatedly will increase the shakiness.
• @0 for a weird fish symbol.
• @(sprite) inserts a sprite into the text. A full list of sprites can be found here.
• Advanced options for sprite usage can be found here.
• # can be used as a line break, but only if the entire line is surrounded in quotation marks e.g. "A BARE HEAD#IS A FAIR HEAD"
