Pocket Edition Mobs
Mobs are living, moving game entities. Generally, mobs are affected by the environment in the same ways as the player—they are subject to physics, they can be hurt by catching on fire (except there is no fire animation yet), falling, drowning, or suffocating, and they can even ride minecarts. When mobs are killed, they drop items which may be useful resources. Mobs come to exist by spawning in various ways. Mobs are aware of players within 16 blocks of them,
The term mob is short for mobile and has been used as a general term referring to any moving entities in games since the first MUDs surfaced.
There are 8 mobs, excluding the player
Passive mobs will never attack the player.
Hostile mobs will attack the player when in range, each with their own abilities. Zombies, Creepers, Skeletons, and Spiders require a light level of 7 or less to naturally spawn. All mobs' hostility levels are based on how they are spawned by default. Spiders may become neutral, but they do not spawn neutral.
