Minecraft Mobs

The term mob, which stands for the word “mobile,” describes the various different types of AI-controlled entities that spawn throughout the Minecraft world. While most mobs can’t pick up resources or remove blocks, enderman are the only ones that can take blocks, they are similar to player characters in that they have a finite amount of health and can react to their environment. Mobs can be either passive, like cows and pigs, or aggressive, like skeletons and zombies. Mobs drop useful resources and items that can be picked up by players.

Players can spawn mobs at will in creative mode by right-clicking while holding one of the mob eggs, which are located at the bottom of the creative mode inventory. They also occur naturally in the game’s environment in areas where certain conditions are met. Mobs also spawn rapidly from their corresponding mob type spawner block, which are found in the nether and in dungeons.

With the exception of ghasts and endermen, mobs only react to players if they are within 16 blocks of them. Enderman have a reaction radius of 64 blocks, while ghasts can notice players as far as 100 blocks away. There are 26 unique mob types as of Minecraft version 1.2.5.

Movement

Once a mob spawns, it stands still or wanders around aimlessly until it detects the presence of a player character. With the exception of ghasts and endermen, mobs only move around when a player is within 32 blocks of them. Mobs move around at random when a player is between 16 and 32 blocks away from them, but they do not know where the player is actually at. Mobs are capable of moving up ladders, although they are rarely able to reach the top before falling off.

Hostile Mobs

Hostile mobs will attack players as soon as they are close enough to notice their presence. Most hostile mobs can only spawn in areas with a light level below 8, although they can wander into illuminated areas in pursuit of a player. Hostile mobs can only spawn in open outdoor areas after the sun goes down, but some spawn on the surface during daylight if there are large enough shadows to create an area with the appropriate level of darkness.

Zombies, creepers and skeletons will slowly die once they are exposed to sunlight. These mobs do not take damage from illumination from other light sources, even if the brightness level is equivalent to sunlight. Spiders that spawned at night remain during the day without taking damage, but they do not exhibit aggressive behavior until it becomes dark again. Spiders will continue to attack you during the day if they began chasing you during the night, or if you engage them in combat at any time.

Passive Mobs

Animals and villagers are passive mobs—they don’t attack player-controlled characters under any circumstances, even if they are being attacked by one. Animal mobs, which include chickens, ocelots, cows and pigs, tend to spawn in illuminated grassy areas. Animals gravitate towards areas that have both light and grass, although they will path towards a dark grassy area before they go to an illuminated non-grassy area. When you strike a passive mob, it will attempt to flee in random directions away from you as you approach it.

Players can attract and befriend various passive mobs by holding certain resources as their active item. Ocelots respond to raw fish, while cows and pigs follow players holding wheat. Players can lead animals into an enclosed area and feed them by right clicking them with the appropriate food equipped. Giving fish to an ocelot or bones to a wolf will eventually tame it, although it may take several attempts.
Once tamed, the animal is friendly towards the player and can be controlled to some extent. Ocelots chase away nearby creepers, while tamed wolves will attack any player or mob that strikes their owner. Feeding also initiates breeding, allowing two or more of the same passive or friendly mob type to reproduce over time.

Interesting Facts

  • Various mobs generate unique noises that alert players to their presence. The sounds are only audible if the mob is within 16 blocks, which is the same range that mobs can detect a player’s location.
  • Mobs will engage one another in combat if one damages the other.
  • Mobs can climb into minecarts and be transported by them, just like a player character.
  • If a moving minecart collides with a mob while moving on a rail, the direction the minecart is traveling will be reversed.
