Features

Spoiler Protection Designed for first-time players. Toggle Unlock Mode to hide all text behind "?". Reveal hints progressively or verify your in-game findings manually without spoiling the rest of the collection.	Search and Filter Full-text search across the entire database. Filter results by Region, Speaker, Type or Tag. Hover over speaker names (e.g. LttM, NSH) to reveal their full canonical names and text color.
Interactive Map Links Most entries are linked directly to the Rain World Interactive Map and related maps. Click the pin icon to see exactly where a Pearl or Broadcast is located in the game world.	Sharing and Exporting Share specific lore entries easily. The URL updates as you browse, storing the selected item and the specific transcriber. Export specific transcriptions as high-resolution PNG files to share quotes.
Source Data View Toggle "Source View" to see the original game file identifiers, internal IDs, raw text strings and source code on selected entries alongside the formatted transcription.	All Transcriptions Switch between different Iterator readings and interpretations for the same pearl (e.g. Moon Pre-Collapse vs. Post-Collapse).

Game Text extraction

If you feel like replicating the dataset yourself, well, here you go. To populate the application with the latest text, you need to extract the strings from the game files.

The scripts are found in site/build-scripts.

Method 1: Mod Extraction

1. Install and run the Text Extractor Mod from the Steam Workshop. The mod will write the extracted files into the following directory: Rain World/RainWorld_Data/StreamingAssets/decrypt
2. In the decrypt directory, rename the language folders from [lang] to text_[lang] (e.g. Eng becomes text_eng).
3. Certain hard-coded strings have been extracted from Rain World/RainWorld_Data/Managed/Assembly-CSharp.dll using dnSpy. Selected files are already included in this repository at dialogue/source/dll. Copy desired dll-File extractions into your decrypt folder alongside the text_... folders.
4. Run the main decryption script inside your .../StreamingAssets/decrypt folder: python path/to/repo/site/build-scripts/decrypt-rw-text.py.
   This will process all text files and the dll sources into a single JSON file.
5. Move the resulting decrypted.json file to the dialogue/source directory in this repository.

Method 2: Old Python Script (Deprecated)

⚠️ This method does not work on broadcasts and is therefore deprecated.

We need to extract the strings from Rain World to use them in the application. Copy the following python program decrypt-rw-text.py into your SteamLibrary\steamapps\common\Rain World folder and run it. This will create a folder decrypted with all the source files in them and a decrypted.json file with all the english variants of the strings.

Copy the decrypted.json file into the source folder.

There is also a custom script available for decoding entire directories of files, with special case handling in case the file was renamed and the salt for the hash differs from the expected one: decrypt-entry.py. It sometimes fails, however; its success rate is roughly 98%, so for the rest we have to fallback on the decryption mod.
