Leopoldo's Spawner Fix

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

Fabric Java 25 License

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 /gamerule commands.

Compatibility & Requirements

Component Required Version
Minecraft 26.1, 26.1.1, 26.1.2, 26.2
Fabric Loader 0.19.3+
Fabric API Matching your Minecraft version

⚠️ Note: Verified by compiling against each release and checking identical BaseSpawner mixin targets (isNearPlayer, serverTick, spawnRange / requiredPlayerRange). Snapshots and version 26.3+ are not supported.


Game Rules

Control spawner mechanics globally across your world using simple /gamerule commands:

Game Rule Default Valid Range Effect
spawner_player_range 128 010000 Maximum distance (in blocks) at which players activate spawners.
spawner_spawn_radius 4 010000 Maximum horizontal block distance around a spawner where mobs can spawn.

Command Examples

# Set player activation distance to 128 blocks
/gamerule spawner_player_range 128

# Expand horizontal spawn area to 16 blocks
/gamerule spawner_spawn_radius 16
