Vide - ValheimItemDataExtract tool

Tool to extract Valheim inventory item data from asset files.

Note: asset files has to be extracted from the game before using Vide. I've successfully used AssetRipper. Short description on how to do that below. One way of doing it.

Credits

I didn't come up with the concept of this program at all. User Brandon-T did, in a discussion here. I just got inspired and wrote my own version in C# and used it as an excuse to explore things related to this. It's somewhat modified to actually work as a real program and not like the hack I started out with.

How to use AssetRipper

How use AssetRipper to extract resources from Valheim, steps below (here as a checklist for easy reference).

1. Get a release (or the source code) from: https://github.com/AssetRipper/AssetRipper
2. Unpack (or build) AssetRipper and run it.
3. Load Valheim game content into AssetRipper:
   1. Select File > Open Folder.
   2. Locate and select Valheim installation folder, i.e., c:\Program Files (x86)\Steam\steamapps\common\Valheim\.
   3. Wait for AssetRipper to load game content.
4. Export loaded game content from AssetRipper:
   1. Select Export > Export all Files.
   2. Select (create if needed) an export folder outside the Valheim installation folder, e.g., c:\temp\.
   3. Wait for AssetRipper to export game content.

Nested within the export folder there should be a folder named Assets (e.g., c:\temp\valheim\ExportedProject\Assets). The path to this folder is what ValheimItemDataExtract expects as "source directory".

Implementation notes

ValheimItemDataExtract is just a simple and very specialized text extractor:

• Get localization data from file localization.txt within the Resources\ subfolder.
• Get item data from prefab files (*.prefab) within the PrefabInstance\ subfolder.
• Export item data to a CSV (Comma Separated Values) file, on item per line.

Assumptions made (that seems to work good enough):

• The name of a prefab file (without .prefab extension) equals the name of the item it defines.
  • Not true beginning with Valheim 0.218.15 (Ashlands). Item data for some items moved to a new file with suffix '_0'.
  • For now, fix is just to remove the suffix. Probably should read name of item from within file instead.
• If a prefab file has a section m_itemData in it, the data within that section defines item data.
• If a prefab file has item data defined, it represents an inventory item only if the item name has a valid translation.
