LokiBlocker: The Ultimate Minecraft Plugin for Granular Block and Entity Control
Running a Minecraft server often means walking a fine line between creative freedom and controlled chaos. Whether you’re managing a survival world, a minigame hub, or a roleplay server, the ability to restrict certain items, blocks, and interactions is essential. LokiBlocker is a powerful Bukkit/Spigot plugin that puts you in the driver’s seat, letting you ban specific blocks, items, crafting recipes, entity interactions, and even chat words with surgical precision.
Key Features of LokiBlocker
LokiBlocker goes far beyond simple block blacklisting. It gives you control over nearly every player action in the game. Here’s what you can manage:
- Block placement and destruction – prevent players from placing or breaking forbidden blocks.
- Inventory management – detect banned items in inventories and optionally delete them automatically.
- Crafting bans – stop specific recipes from being used in workbenches, furnaces, and other crafting stations.
- Pickup and drop prevention – block players from collecting or discarding prohibited items.
- Interaction control – restrict left-click and right-click actions on both items and blocks.
- Environmental hazards – toggle whether banned blocks can burn, explode, or be moved by pistons.
- Entity protection – shield mobs from damage types like attacks, projectiles, lava, drowning, magic, poison, and more, plus block player interactions with them.
- Chat filter – replace forbidden words with asterisks to keep chat clean.
- Biome-specific and world-specific rules – apply restrictions only in certain biomes or worlds.
- Per-player permission overrides – grant trusted players bypasses for specific actions or items.
Configuration Files Explained
LokiBlocker uses several YAML files to define its behavior, giving you layered control that can be as broad or as fine-tuned as you need.
config.yml – Global Settings
The main configuration file enables the plugin and sets default behaviors. You can toggle whether the plugin actively removes banned blocks from newly loaded chunks (force mode) to clean up existing violations. The id-data list defines which blocks or items are banned globally using the format 'id:data' (for example, '8' for water, '35:0' for white wool). From there, you independently enable or disable checks for placing, breaking, crafting, inventory presence, pickup, drop, and various interactions. The plugin also supports chat word filtering and global entity interaction rules.
list.yml – Group-Based Restrictions
Instead of a flat ban list, LokiBlocker lets you group items and blocks under custom names. Each group can have its own set of allowed actions—place, break, craft, pickup, drop, burn, explode, piston push/pull, and more. This makes it easy to create themed restrictions, like a “banned_wool” group that prevents all wool placement but still allows breaking. The list format uses item IDs with optional data and damage values, giving you control over exact variants such as colored wool or damaged tools.
entities.yml – Entity Protection
Entity rules are defined per mob type. You can block specific damage sources (attack, projectile, contact, drowning, lava, lightning, magic, poison, suffocation, explosion, fire) and even prevent players from interacting with the entity. Biome lists can limit these rules to certain biomes, so a creeper might be invincible in a desert but vulnerable elsewhere.
configurable.yml – Advanced Per-Block Customization
This file offers the deepest control. You can override the global settings for specific blocks or items, adding coordinate boundaries (min/max X, Y, Z), biome restrictions, and world-specific rules. For example, you could allow diamond ore to be mined only in a certain area of your spawn world while banning it everywhere else. Each entry can fine-tune place, break, craft, inventory, pickup, drop, interactions, explosion, burning, and piston behavior independently. This level of detail is perfect for adventure maps or complex server economies.
Setting up LokiBlocker on your server is straightforward—just drop the JAR into your plugins folder and edit the YAML files. For those who prefer a streamlined setup, the LokiBlocker plugin can be quickly added to your server using the foxygame.net launcher, a modern and flexible tool that lets you download and manage mods directly from its built-in menu.
Permissions for Granular Access
LokiBlocker’s permission system is incredibly detailed. Instead of a simple “bypass all” node, you can grant players the ability to place or break specific banned blocks, carry them in inventory, craft them, or interact with entities. Permissions follow patterns like lokiblocker.place.allow.<id[.data]> for standard bans and lokiblocker.custom.place.allow.<id[D<data>][U<damage>]> for custom configuration entries. There are also group-based permissions (lokiblocker.list.allow.<group_name>) that unlock all actions for items in a defined group. This means you can create a VIP rank that bypasses wool restrictions while keeping other players locked down.
Practical Use Cases
LokiBlocker shines in scenarios like preventing griefing by banning TNT and flint-and-steel; creating adventure maps where players cannot break certain blocks; disabling overpowered mod items; building a safe trading zone where dropped items are instantly deleted; or even filtering chat to keep the server family-friendly. The biome and world-specific rules let you design unique regional mechanics—imagine a nether fortress where fire damage is disabled for players but still affects mobs.
LokiBlocker is a must-have for any server administrator who needs precise control over the Minecraft environment. Its layered configuration, entity protection, and extensive permission system make it adaptable to almost any server type. Whether you’re running a small community server or a large network, this plugin provides the tools to enforce your rules without compromising performance.
