Packdev Toolkit
A collection of developer tools for building modpacks and datapacks. Pull textures/models out of resource packs,
dump lang entries, search datapacks, and copy item IDs: all without leaving the game!
Requirements
Features
Export hovered asset/recipe (O)
Press the export key (default: O) to pull whatever you're looking at into a checklist screen, where you pick which
files to copy into your export folder:
- Looking at a block: grabs every texture used by its current block model (including block entities like chests).
- Looking at an entity: grabs its texture.
- Holding an item: grabs the item's texture(s).
- Hovering an item in EMI: same as holding it.
- Hovering a recipe in EMI's recipe viewer: saves the recipe straight to a datapack JSON file (singleplayer
only).
Hold Shift while pressing the export key to instead grab the raw JSON definitions (blockstate + block model, or
item model) instead of the PNG textures.
Selected files are copied into your configured export directory (see Configuration) and the containing
folder is opened for you automatically.
Copy translation key (J)
Press the copy key (default: J) while looking at a block/entity, holding an item, or hovering an item in EMI to
copy its lang entry to your clipboard:
"item.minecraft.diamond": "Diamond"
Handy for quickly building en_us.json entries for modpack renames.
Dump item IDs (/export)
Grabs item IDs posts them to chat as a single copyable JSON array (click the message to copy it to your clipboard).
Useful for making tags or loot tables without manually typing IDs.
| Command |
Dumps |
/export hand |
The item in your main hand |
/export hotbar |
All 9 hotbar slots + offhand (duplicates ignored) |
/export inventory |
Your entire inventory (duplicates ignored) |
Search datapacks for item/block usage (/query)
Requires OP. Scans every loaded datapack for references to a given item or block and writes
the matching file IDs to a JSON file in your export folder (queries/ subfolder), then links the file in chat.
| Command |
Searches |
/query find_item_in_loot <item> |
loot_table and loot_modifiers JSON for the item ID |
/query find_block_in_features <block> |
worldgen/configured_feature JSON for the block ID |
/query find_block_in_structures <block> |
.nbt structure files whose block palette contains the block |
Useful for answering "which loot tables have this?" or "which structures use this block?" without manually searching
through datapack files.
Configuration
Accessible from the config screen in-game using YACL, or packdev_toolkit.json in your config folder
Export Directory
The root folder that assets, recipes, and /query results are written to. Can be relative to the game/server directory
(default packdev_toolkit_exports) or an absolute path (e.g. C:/Users/Name/Downloads).
Exports are namespaced as assets/ (textures, blockstates, models), data/ (recipes), and queries/ (/query
results).
Keybinds
Keybinds are rebindable through the Controls screen under the "Packdev Toolkit" category.
