Additions

Non-mob entities

File:Steve (slim) JE2.png Minecraft:Mannequin

• Added a new type of technical entity called minecraft:mannequin which can only be spawned with summon commands.
  • A mannequin is a player avatar without a connected player.
  • Mannequins always show an "NPC" text where a Player's below_score score would show.
  • Mannequins function as living entities, like Minecraft:armor stands.
    • They can hold and wear equipment, have attributes & effects, take damage, etc.
  • Data Fields:
    • profile - Which profile to show on the entity. This is either a Player profile (same format as a minecraft:profile component) or a Mannequin profile with the following fields:
      • texture - Namespaced ID of the skin texture to use.
        • The skin is specified relative to the textures folder and with a .png suffix.
        • e.g. entity/player/wide/steve will use the default wide Steve skin.
      • cape - Optional namespaced ID of the cape texture to use.
        • When specified, uses the same format as the texture field.
        • Omitting this field means the mannequin has no cape.
      • elytra - Optional namespaced ID of the elytra texture to use.
        • When specified, uses the same format as the texture field.
        • Omitting this field means the mannequin uses the cape texture, or if that is also omitted, the default elytra texture when wearing elytra.
      • model - Optional model type, one of wide and slim.
        • If omitted, wide is used.
    • hidden_layers - List of outer skin layers to hide.
      • Valid entries: cape, jacket, left_sleeve, right_sleeve, left_pants_leg, right_pants_leg, hat.
    • main_hand - Which hand is the main hand of the mannequin.
      • One of left and right.
  • This entity highly resembles the Mob entity removed long ago in Beta 1.2, as it is has a player skin and has no movement AI.

Changes

Blocks

• Adjusted the colors to make them more discernible to color blind players.

Minecraft:Shelf

• Powered shelves can now only connect to other powered shelves facing the exact same direction.

General

Minecraft:End flash

• While the ender dragon fog effect is active, the flash source in the sky is not visible and the brightness of the light affecting the world is reduced.

Minecraft:Key binds

• Multiple key binds that have the same key assigned to them can now work together, while before only one would work.
  • For example, it's now possible to bind the Template:Key key to Jump and Strafe Left, to jump and strafe left at the same time.

• Added a Spectator category in the key binds screen, alongside the pre-existing Highlight Players key bind.
