Item Blacklist: Ban Items and Blocks by Dimension
In the complex ecosystem of modded Minecraft, maintaining server balance requires precise control over item usage across different dimensions. The Item Blacklist: Ban Items and Blocks by Dimension add-on provides exactly that level of granular administration. This utility allows administrators to strictly limit specific items and blocks within chosen worlds without breaking the crafting mechanics elsewhere. It is an essential component for any stable modpack seeking rigorous rule enforcement.
Tailored Restrictions Across Dimensions
The primary function of this modification is dimension-specific prohibition. In many multiplayer environments, a rare item might be permissible in The Overworld but strictly forbidden in the Nether or custom dimensions generated by mods. This tool resolves that conflict instantly. By defining specific identifiers and target worlds, the game engine ceases to allow application of banned items within those contexts.
Server-Side and Client Installation
A critical aspect of deploying Item Blacklist: Ban Items and Blocks by Dimension is ensuring installation on both the client side and the server. If installed only on one, the locking mechanics will fail for other participants in a multiplayer session. For those utilizing launchers like FoxyGame to manage their installations effortlessly, this mod can be pulled directly from the menu without manual file management.
To proceed with the download Item Blacklist: Ban Items and Blocks by Dimension, ensure your launcher supports version 1.2 or higher. This specific version introduced dual-list functionality that separates world-specific rules from pack-wide configurations, simplifying updates significantly.
Dual List Architecture for Stability
Starting with the internal build of version 1.2, the mod operates using two distinct lists simultaneously:
- World Blacklist: Configured via commands and stored locally in
/worlds/<name>/data/itemblacklist.json. This allows server admins to apply temporary or event-specific bans without touching the core pack files. - Pack Blacklist: Located strictly within
config/ItemBlacklist.json. This file is immutable from in-game commands and should be managed by modpack authors. It sets baseline rules for all servers running that specific collection of mods.
This architecture prevents conflicts during updates. When a pack author releases version 1.2, the global Pack Blacklist is updated to reflect new compatibility standards. Simultaneously, server administrators can override these defaults using their local World files if they need stricter security measures.
The Locked Item Mechanic
Beyond simple blocking, this add-on introduces the concept of "Locked Items". When an item is banned in a specific dimension, it does not vanish; instead, it enters a "shell" that neutralizes its usage. A player holding a prohibited block cannot place or use it within the restricted zone. This mechanic serves as immediate visual feedback to players regarding server rules.
Maintenance and Command Usage
The mod relies heavily on console commands for dynamic management, eliminating the need to reload world data files frequently.
/blockitem list:Displays all currently banned items grouped by dimension. Use this to audit your server's security posture quickly./unpack <id>:Extracts an item from the lock shell, allowing for legitimate use after manual review or debugging events./pack list: Shows items banned globally across all dimensions via the config file. This is useful when verifying that a modded block was correctly added to the pack blacklist by its developer.
If you are managing a large network, consider utilizing plugins like LuckPerms with verbose modes to debug permission interactions alongside these item bans. Always remember that removing a ban on a packed list requires manual editing of config/ItemBlacklist.json, as commands cannot override the static pack files.
In conclusion, how to install this modification is straightforward but requires attention to dual-file management for long-term stability. By separating world-level overrides from global configuration rules, you create a flexible environment where server admins can enforce economy balance without constantly fighting against modpack updates. This ensures that items breaking game progression are neutralized regardless of the biome or version content active in your specific build.
