Monster Spawner
minecraft:spawnerA Monster Spawner is a special block found in structures like dungeons, mineshafts, nether fortresses, strongholds, bastion remnants, and woodland mansions that continuously attempts to spawn a specific mob near players. It displays a rotating miniature of its mob and requires proper light and space conditions to spawn successfully.
FAQ
Can I obtain a Monster Spawner in Survival mode?
No, spawners cannot be broken and collected in Survival even with Silk Touch; they are only obtainable in Creative mode or via commands.
How do I stop a spawner from producing mobs?
Fill the surrounding spawning volume with solid blocks or raise the light level enough to prevent the target mob type from spawning.
How close does a player need to be to activate a spawner?
A spawner activates and attempts to spawn mobs whenever a player comes within 16 blocks of it.
Can I change which mob a spawner produces?
In Creative mode, using a spawn egg on the spawner reconfigures it to spawn that egg's mob type instead.
