About this project
What does ItemBlocker add?
The mod is a server utility for blocking unnecessary or breaking the game items on the server.
With it you can block an item completely, the mod listens to item creation events, drops, pickups, right and left clicks of the player and detection in containers. The mod also checks for the presence of a prohibited item in the merchant menu.
When an item is blocked, it is also instantly deleted from all online players on the server.
Since version 1.0.1 there is integration with Curios API.
You can find the list under [save_name]/serverconfig/itemblocker.json
You can also create a default blacklist under defaultconfigs with the name itemblocker.json. This will automatically be applied to every new world you create.
You can find the config of mod in config/itemblocker/itemblocker.toml
Commands:
- /itemblocker ban hand - ban item of the hand
- /itemblocker ban minecraft:stone - ban minecraft stone
- /itemblocker unban minecraft:stone - unban minecraft stone
- /itemblocker list - list all banned items
All commands require operator rights
The mod has been tested on servers with a large number of mods and players. The mod does not cause performance problems and the server-safe is specially made.
Feel free to write about all problems and suggestions on my github! Good luck!
