Mobs

General

• Mobs have a 5% chance to spawn left-handed, through the new LeftHanded boolean tag.
  • Mobs able to hold items hold them according to their dominant hand.

File:Shulker.png Shulkers

• Short for "Shell Lurker".
• Hostile mobs with the appearance of a purple block.
  • Only spawn on the ground or at the walls of End cities when they first generate.
• When attacking, they open their shell with a spinning animation, revealing the creature inhabiting.
  • The creature looks like a little white cube with big eyes.
  • Its attack consists of shooting projectiles.
    • The projectiles chase the player until the projectile is out of range.
      • They can only move along one of the three grid axes at a time and on integer steps.
        • This means they can move only via taxicab geometry.
    • Projectiles can be knocked away by attacking them.
    • Getting hit by a projectile causes 2 hearts of damage and inflicts the Levitation status effect.
    • They take more damage while their shell is open.
      • Their shells are considered armor, and bounce arrows off.
  • It has an idle animation, where it opens its shells a little to peak through.
• Can be pushed by Minecraft:pistons, and can exist only on coordinates that are integers (except if they are on Minecraft:minecarts).
• Can teleport like an Minecraft:enderman.
  • Sometimes does this while being attacked or placed in unusual circumstances:
    • Removing its support block.
    • Pushing it into a non-air block (except piston heads).

File:Chorus plant.png Chorus trees

• Tree-like arrangements of the new chorus plant and chorus flower blocks.
• Generate on the outer End islands
• The whole structure is destroyed when the bottom-most block is destroyed, like cacti.
• Can be farmed by planting the chorus fruit flowers that come from the top of the plants.
  • Unlike cacti, chorus plants do not require the supporting block to be below it, but rather adjacent.
    • This allows the structure to grow around obstacles, like other plants.

File:End gateway JE1.png End gateways

• Small structures consisting of an End gateway block and two little bulbs of bedrock, at both the bottom and the top.
  • Are an alternative way of traveling to the outer End islands, without having to build or fly all the way over there.
  • Since the bulbs of bedrock only leave a one block slit on the horizontal plane, it is only accessible by throwing ender pearls at it, or by riding Minecraft:pigs, Minecraft:boats or Minecraft:minecarts.
    • The player is teleported to somewhere on the outer End islands.
    • The final location of the player depends on what angle they entered or at what angle the ender pearl was thrown at.
• One gateway is created for each dragon kill.
  • Up to 20 gateways are possible to create this way.
  • Gateways spawn in a radius around the End portal.
  • Another gateway is created every time the player teleports to a new location.
    • The created gateway is linked to the original, so the player has a way back.

Gameplay

Dominant hand option

• An option for players to change their dominant hand on their player model.
  • Under "Skin Customization".
• Changes the orientation of the offhand slot in the hotbar (left often suits right-hand players better and vice versa).

Dual wielding

• Players can now use both hands at the same time to do different actions, with the left and right mouse buttons.
  • For example, if a player has a pickaxe in their main hand and a torch in their other hand, right clicking places the torch.
    • This happens because a pickaxe lacks a right click use, and therefore the game tries to then treat the other item as if it's being right clicked.
    • The player cannot click both buttons at the same time.
  • This is achieved through an extra inventory slot called the "offhand" slot.
    • Pressing Template:Key (by default) switches whatever item is selected in the hotbar with the item in the offhand (including no item).
    • The offhand slot is displayed next to the hotbar when it's not empty (left for right-hand players and vice versa).
      • It's also available in the Minecraft:inventory screen.
• Only the main hand can be used for attacking.
  • Even bows can't be used in the offhand.
• Minecraft:Bows can be used when something else is in the offhand.
  • Arrows in the offhand take priority over arrows in the rest of the inventory slots.
• The offhand model is invisible in first person view, while it's empty.
• Some attributes and enchantments apply to the offhand item, while others do not.

Status effects

• Template:EffectLink
  • Received when the player is hit by shulker projectiles.
  • Makes player involuntarily float high into the air.
    • Can be used to get to higher places.
  • Listed as a negative effect, due to the potential to kill from fall damage.
  • Higher levels of Levitation result in faster floating, except for the last two:
    • Level 255 does nothing.
    • Level 254 results in slow fall (similar to lunar gravity).

• Template:EffectLink
  • Received when players or mobs are hit by spectral arrows.
  • Makes player's outline glow, seen even through non-transparent blocks.
    • The outline includes the models of the currently held items.
  • Listed as a negative effect, because it prevents players from hiding from other players.
  • It becomes colored differently if the player is part of a team, to match its team color.

• Unlike other blocks, Minecraft:chests, trapped chests and ender chests have their item model rotated, to have the front face in view of the player.

• The dragon AI and attacks has been changed:
  • Breathes fire/purple particles on players and mobs, while on top of the portal.
  • Drops fireballs on top of the player.

  • They are ordered by the time of infliction from right to left.
