What can slimes not spawn on?

Answered by Stephen Mosley

Slimes in Minecraft have specific spawning requirements, and there are certain blocks on which they cannot spawn. One effective way to prevent slime spawning is by using half-blocks, also known as slabs. Slabs are blocks that occupy only half of the vertical space of a normal block, and they can be made from various materials such as wood, stone, or even nether bricks.

The reason slimes cannot spawn on slabs is because mobs require a full block of space to spawn. Since slabs only occupy half of the space, there is no room for mobs, including slimes, to spawn on them. This makes slabs an excellent choice for creating floors in your base or any other area where you want to prevent slime spawning.

Another option you can consider is using glass blocks for your floors. Mobs, including slimes, cannot spawn on transparent blocks like glass. So, if you want to be extra sure that no slimes will spawn in your base, using glass blocks for the floor can be a great solution. Plus, glass floors can give your base a unique and modern aesthetic.

It’s worth noting that slimes have specific spawning requirements in terms of location and light levels. Slimes only spawn in specific chunks below level 40, and they require a light level of 7 or lower. By building your base above level 40, you can ensure that slimes won’t spawn naturally in your immediate vicinity.

To summarize, slimes cannot spawn on half-blocks or slabs because they require a full block of space to spawn. You can also use glass blocks for your floors, as mobs cannot spawn on transparent blocks. Additionally, by building your base above level 40, you can further avoid slime spawning as they only spawn below this level. Remember to consider the specific requirements and limitations of slime spawning when planning and designing your Minecraft base.
