Monster Spawner

Mob Spawners are blocks with a transparent blue lattice structure found in dungeons. Inside it are flames, though it does not give off any light, and a miniature model of the mob it spawns, continuously spinning and getting faster until the mob spawns in the area around the cage. A spawner has a range of around five blocks, and it will continue to create mobs in any dark spaces within that area, even if there is a wall between the spawner and the destination, until these areas are lit up. This has lead to many contraptions designed to kill whatever drops from it, usually a drowning trap, allowing the player to collect spoils in great numbers with little risk. There is a bug that comes up rarely where a mob spawner "spawns" and there is no visible enemy, though sounds can be heard and when you move closer the mob sometimes appears.



When found inside dungeons naturally, they will either spawn Spiders, Skeletons, or Zombies. While they can be destroyed by a pickaxe or by hand, they can no longer be picked up by the player. When placed by the player, they would only spawn pigs. These player placed spawners will only create pigs when in or near direct light.

Mob spawners can be edited to spawn mob entities. However, mob spawners cannot be modified to spawn slimes. This is likely because slimes have a size variable.
