Iron Golem

Iron golems are large, strong utility mobs that defend villagers.

Villages
Golems will spawn in a 16×6×16 area, centered between the 21 or more valid doors in a village if it has at least 10 villagers. The chance of spawning is 1 in 7000 per game tick, which averages around one every six minutes. Iron golems can spawn provided the blocks it spawns in are transparent and the block it spawns on top of has a solid surface.

Creation
The golem can also be constructed by placing blocks in a similar fashion to snow golems and withers. It is created by placing four blocks of iron in a T shape (as shown in the image), and then placing a pumpkin or jack o'lantern on top of the center upper block. The pumpkin may be placed by the player, by a dispenser or by a pumpkin stem, but it must be placed last.

The block arrangement can be placed vertically or horizontally. The four empty spaces in the diagram (above and below each of the arms) must be air blocks. Any non-air block (including blocks such as snow, tall grass, and water) present in any of the empty spaces will prevent the golem from spawning.

Like other constructed mobs, iron golems always spawn facing south. Their large size may cause them to take suffocation damage from nearby solid blocks at the level of their head.

Drops
Iron golems drop 3–5 iron ingots and 0–2 poppies upon death.

The Looting enchantment is ineffective against iron golems as it does not give any extra iron ingots or poppies when killed.

Behavior
Iron golems are 2.7 blocks tall and 1.4 blocks wide.

Iron golems will wander around a village in a patrol-like fashion, staying close to the edges of buildings and other structures. Like villagers, iron golems will not wander away from a village, regardless of how they were spawned. Iron golems will sometimes face a villager, as if they are speaking to each other. Iron golems are able to spawn poppies in their hands and offer them to villagers, symbolizing the friendly relationship between the villagers and golems. However, they won't spawn and offer poppies to other iron golems.

If not within a village, iron golems will slowly wander aimlessly.

Iron golems can walk up a full block height without jumping and walk over a 1 block wide hole without falling in. They will avoid water, lava, fire and cacti. Iron golems are immune to both drowning and fall damage. When in water, they will sink, immobilize, and become passive, but will still be pushed by flowing water.

Like all utility mobs, iron golems can be leashed.

Attacking
When provoked, an iron golem will move quickly toward its target and once in range will swing its arms up violently to attack, dealing to  damage and flinging the target into the air. This attack is potentially the 3rd strongest Overworld attack in the game, beaten only by the explosion of a creeper or charged creeper. Iron golems have a comparatively large attack range, allowing them to attack through a solid 1 block thick wall, even without a line of sight to the target.

Iron golems will attack any hostile or neutral mob within 16 blocks of them, except wolves, polar bears, creepers and llamas.

Naturally spawned iron golems will attack the player if the player attacks them first, but will give up if the player moves out of their search radius. The iron golem will also attack the player if they attack a nearby villager, and does not have to directly see the player to become hostile. They will automatically attack any players with a popularity of -15 or lower. Any iron golems built by the player will never attack players under any circumstances, but will still protect villagers from zombies.

Iron golems have a chance of accidentally hitting another mob while attacking a hostile mob. Additionally, it is possible for multiple golems to simultaneously hit the same target. The height to which the victim is sent flying is relative to the number of golems that attack it.

Iron golems may also target snow golems if first hit by one of their snowballs, usually killing the snowman in one hit.

Being attacked
Zombies, skeletons, spiders, cave spiders, slimes, and magma cubes will naturally attack iron golems on sight, and may cause major damage, especially if the mobs attack in groups. If an iron golem is attacked by multiple mobs, it will retaliate in the order it was attacked.

Iron golems have 100% knockback resistance.

Data values
Iron golems have entity data associated with them that contain various properties of the mob. Their entity ID is.

Trivia



 * The iron golem's holding out flowers to villagers, and their being covered in vines, are references to the ancient robots in Hayao Miyazaki's animated film Laputa: Castle in the Sky.
 * When villager children notice the poppy in its hand, they will slowly approach, and take the flower eventually. Iron golems do not actually pick up poppies; they spawn them in their hands.
 * Tamed wolves will continue to attack iron golems even after the iron golems have turned passive towards the player.
 * If a player throws an ender pearl at an iron golem, it will become hostile.
 * Two iron golems may fight each other. The golems will stand face to face and slowly back up, until one or both charge in quickly.
 * Even with a poppy in its hands, an iron golem can still hit a hostile mob.

 * The iron golem is a purchasable avatar item on the Xbox 360 Marketplace.
