Leopoldo's Spawner Fix
- By
Bring back useful mob spawners! Spawner Fix removes the annoying 16-block proximity limit, extending the activation range to a full 128 blocks to match normal mob spawning.
Spawner Fix
A lightweight, performance-oriented Fabric utility that introduces server-wide game rules to control mob spawner activation ranges and spawn radiuses natively.
Features
- ⚙️ In-Game Configuration: Adjust spawner ranges dynamically using standard vanilla
/gamerulecommands.
