Tutorial:Spawn-proofing
This tutorial page is a work in progress.
Please help expand and improve it. The talk page may contain suggestions.
Hostile mobs spawn in and around your builds at zero block light level and at most 7 internal sky light level. Mobs such as creepers have the potential to destroy your creations, while others may attack you. There are many ways of preventing hostile creatures from spawning.
Basic spawn-proofing
- Light blocks
- One of the most basic ways to prevent mob spawning is by placing torches or other light sources. These increase the light level around them, stopping hostile mobs from spawning. Other blocks such as glowstone or shroomlight emit higher light levels, but are harder to come by. This method does not work with mobs whose spawning does not rely on low light level, such as slimes, magma cubes and hoglins. The most efficient distance for torches is about 14 blocks to the next torch.
- Slabs and partial blocks
- Mobs cannot spawn on blocks that are less than a full block in height. Areas covered in bottom slabs are unable to spawn mobs, no matter the light level, although double slabs, top slabs and upside-down stairs are still spawnable. Also, dirt path and farmland are partial blocks (15/16th of a block in height) and cannot be spawned upon.
- Transparent blocks
- Mobs also cannot spawn on top of transparent blocks, such as glass, or partially transparent blocks, such as leaves.
- Carpet
- Mobs cannot spawn on carpets because they are not a full block.
- Snow layer
- Snow layers of thicknesses 2 to 7 prevent hostile mobs from spawning. (only one layer of snow doesn't work, as it is not possible to step on it, you can tell that your height doesn't change when you walk over it.)
- Redstone components
- Mobs cannot spawn on buttons, levers, pressure plates, and all types of rails. This does not include string.
- Fluids
- Mobs other than water mobs are unable to spawn in water. Mobs other than striders are unable to spawn on lava.
(Side note: You can download mods to show where you have to spawn-proof for your mob farm or entity removing needs.)
