Carpet has the same visual thickness as a pressure plate. It has a hitbox of 1 ⁄ 16 of a block and covers the entire surface of the block it is placed on. This thickness prevents mob spawning. Carpet can be placed on any block, including non-solid blocks, except paintings and item frames.
Does carpet keep mobs from spawning?
Yes, yes they can. The only block enderman cannot teleport on is double thick carpet. Yes, it must be double thin I. Some others that don’t work include water, slabs, fences, glow stone lamps, red stone and many more. Remember just because they cannot spawn on it does not mean they cannot teleport.
Do mobs cause monster spawners to spawn mobs?
When you move closer to a spawner, you will see flames burning and a miniature version of the mob will appear inside and spin faster and faster. If the light conditions are right, eventually, the mob will spawn outside of the monster spawner. A monster spawner is an item that you can use and place anywhere in the game yourself.
Most mobs never spawn on transparent blocks, in water (except fish, dolphins, turtles, and other aquatic creatures), in lava (except for striders), on bedrock, or on blocks less than a full block tall (such as slabs placed on the bottom half).
Hostile mobs spawn, but they deal less damage than on Normal difficulty. The hunger bar can deplete, damaging the player until they are left with 10 if it drains completely. Cave spiders and bees cannot poison players on Easy difficulty, and the wither does not cause the Wither effect, although wither skeletons do.
