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 ```
