About this Mod
Where Is My Shulker?
This mod keeps track of every shulker box you place or break in a world so you never again have to wander around your world searching desparately for your valuables.
It adds a simple command to interact with the tracked data.
✨ Features
- Tracks all placed and broken shulker boxes
- Records:
- Location
- Custom name (if set)
- Shulker box color
- Lists all currently placed shulkers on demand
- Shulker box list supports pagination for messy evenings
- Simple command to clean the list
- Stores data in csv format
📜 Commands
/shulker
Displays a list of all currently placed shulker boxes, including:
- Custom name or box color
- Coordinates
- Color
The output is paginated, if necessary.
/shulker clear
Clears all unnamed and undyed shulker boxes from the list.
/shulker clearall
Clears all shulker boxes from the list.
💾 Data Storage
All data is saved as a CSV file. For Singleplayer worlds the path is <world folder>/data/shulker_boxes.csv.
On Multiplayer servers shulker boxes are stored in .minecraft/.whereismyshulker/<serverip>_<port>/shulker_boxes.csv
📝 Notes
- Only shulkers broken by the player get removed. Explosions or piston movement isn't tracked.
- I've searched extensively for an existing solution to this issue but without any success. I did find 9 year old reddit posts asking the same question, but since this appears to be an unsolved problem I wanted to take it into my own hands, since I regularly struggle with lost shulker boxes.
