Disable Spawner Mob Spawns
This datapack flips the new gamerule spawnerBlocksEnabled to false, so mob spawners stop spawning mobs. Natural spawning is untouched.
⚠️ Requires Java Edition snapshot 25w37a or newer (the snapshot that introduces spawnerBlocksEnabled). Works in single-player and servers.
What it does
- On world load, sets:
``` /gamerule spawnerBlocksEnabled false ```
- Result: all mob spawners won’t spawn anything.
- Does not change natural spawning, eggs, commands, or mob farms that don’t rely on spawners.
Install
Drop the ZIP into your world/server datapacks/ folder.
Run /reload (or restart the server).
Uninstall
Remove the datapack.
Re-enable spawners with:
``` /gamerule spawnerBlocksEnabled true ```
