Mob Stacker Lite is a lightweight, high-performance optimization addon designed to eliminate entity lag on your Minecraft Bedrock server or single-player world. By intelligently merging nearby identical mobs into single entities with dynamic property counters, it vastly reduces server CPU overhead while retaining full vanilla mechanics.
🛠️ Key Features
No Experimental Gameplay Required: Built entirely on fully stable releases of the Bedrock Script API (@minecraft/server and @minecraft/server-ui). Safe to deploy on long-term survival worlds and realms without risking world stability or corruption.
Intelligent Auto-Merging: Automatically detects and condenses identical mob types within a 3-block radius into a single entity, dynamically tracking the stack size directly on the host creature.
Dynamic Nametags: Seamlessly displays the exact cluster size in real-time above the mob using clean formatting (e.g., ZOMBIE [x12]).
True Loot Scaling: When a stacked mob is slain, the addon automatically triggers underlying drop engines to replicate the exact loot yields of every single mob compressed inside the stack.
Cumulative Experience Injection: Bypasses engine bottlenecks by mathematically calculating the total missing experience points from a defeated stack and instantly piping that XP directly into your player bar.
Named Mob Protection: Built-in intelligence automatically detects if a mob has been given a custom name (e.g., via a standard Nametag item) and safely exempts them from being sucked into any nearby stacks.
📜 How to Use
To manage your world's entities or isolate specific creatures from the global stacking algorithm, utilize the integrated Stack Blocker Utility:
Craft the Tool: Place any standard item (such as a Stick or a Feather) into an Anvil and rename it exactly: Stack Blocker
Open the Control Menu: Hold your newly created tool and Right-Click / Use the item. This instantly prompts a native graphical interface to open on your screen.
Toggle Stacking Status: The interface dynamically scans a 10-block radius around you and renders a button for every nearby mob. Each button lists the mob type alongside a status indicator: [STACKING ENABLED] or [STACKING DISABLED].
Isolate or Release: Click a mob's button to toggle its status. Disabling a mob instantly separates it from the cluster logic (indicated by green validation particles), allowing you to keep specialized farm configurations, pets, or decorative mobs completely safe.
