Additions

Mobs

File:Skeleton Trap Revision 1.png Minecraft:Skeleton horsemen

• Added "skeleton trap" horses. When a player approaches to within 10 blocks, the following happens:
  • The SkeletonTrap flag is cleared.
  • Minecraft:Lightning strikes the horse.
  • The horse becomes skeletal if it isn't already.
  • The horse becomes tamed.
  • The horse becomes fully grown (if a baby) and the breeding cooldown is reset.
  • A skeleton is spawned riding the horse.
    • If on Peaceful, the skeleton doesn't spawn, while the horse does.
    • The skeleton has damage immunity for 3 seconds.
    • The skeleton doesn't despawn, since it has the tag PersistenceRequired set to true.
    • The skeleton is wearing an iron helmet, unless it randomly spawned with some other headgear.
    • The skeleton's bow and helmet are Minecraft:enchanted as if on an enchantment table at level 5–22.
      • The level is higher depending on Minecraft:regional difficulty; on Easy it is always a level-5 enchantment.
  • Three additional skeletal horses with riders are spawned in the vicinity.

Command format

Minecraft:NBT format

• SkeletonTrap (byte): Indicates whether the horse is a skeleton trap (i.e. whether or not the horse will spawn 4 undead horsemen in its place when a player gets within 10 blocks of it).
  • /summon EntityHorse ~ ~1 ~10 {SkeletonTrap:1b}.
• SkeletonTrapTime (integer), incremented each tick when SkeletonTrap is set to 1. The mob automatically de-spawns when it reaches 18000 (15 minutes). This will prevent the hostile horses from overflowing the world, similar to chicken jockeys.
  • /summon EntityHorse ~ ~1 ~10 {SkeletonTrap:1b,SkeletonTrapTime:17980}.

Minecraft:Statistics

• Added "Times Slept in a Bed" (stat.sleepInBed) to track the amount of times a player has used a Minecraft:bed.

Changes

Blocks

All sloped Minecraft:rail types

• Hitbox heights are decreased from 10 pixels of block to about 2.5 pixels of a block.

Crops

• Improved drop chances for seeds (average Template:Frac per crop harvested instead of Template:Frac), Minecraft:potatoes and Minecraft:carrots (average Template:Frac per crop harvested instead of Template:Frac), and Minecraft:beetroot seeds (average 2 per crop harvested instead of Template:Frac).

Minecraft:End rod

• The player can no longer step up onto an end rod as if it was a Minecraft:slab or Minecraft:stairs.

Minecraft:Fire

• Goes out less often under the rain.
  • The chance of going out each fire tick is reduced from 100% to 0–45%, depending on the age property.

Mobs

General

• Improvements to mob AI.

Minecraft:Skeletons

• Have new idle sounds.
• Skeletons can now walk, strafe and shoot at the same time.
  • They walk away from players that are too close and toward players that are too far.
    • They also sprint toward the player when very far away.
• Now can spawn riding "skeletal horses" through the new "skeleton trap" horse.

Tamed Minecraft:ocelots & Minecraft:wolves

• Deaths (and killers) are now announced to their owners on Minecraft:chat, even if unnamed.

Minecraft:Villagers

• Now pick up and plant Minecraft:beetroot seeds.
• Now pick up Minecraft:beetroot and use it in the same way as they do Minecraft:carrots and Minecraft:potatoes.

Non-mob Minecraft:entities

Minecraft:Lightning

• Natural lightning strikes may spawn a "skeleton trap" style skeletal horses.
  • Chance is calculated from the Minecraft:regional difficulty score: 5% * raw regional difficulty score.
    • 3.75–7.5% chance on Easy, 7.5–20% chance on Normal, 11.25–33.75% chance on Hard.

Trivia

• 15w38a was previously removed from the Minecraft:launcher for some time, but was added back in September 2018.
