Minecraft 1.21.9 Snapshot 25w36a (b) – NPC Dummies and Performance

1 day ago

Mojang Studios

Minecraft 1.21.9 Snapshot 25w36a (b) is the next test version of “The Copper Age.” The most notable highlights of this snapshot are the addition of a new technical entity that can only be summoned via the summon command. The Mannequin functions as an NPC, capable of wearing armor, holding items, taking damage, receiving effects, and displaying “NPC” below its name instead of a score. Now, each dimension (Overworld, Nether, End, etc.) can have its own distinct border size and position. It is also possible to assign the same key to multiple actions, and they will all function simultaneously.

Features:

Non-mob entities

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 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 has a player skin and has no movement AI.

Changes

Blocks
- Copper lanterns and copper torches
  - Adjusted the colors to make them more discernible to color blind players.
- Shelves
  - Powered shelves can now only connect to other powered shelves facing the exact same direction.
General
- Data pack
  - The pack format version is now 86.0.
- 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.
- 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 d key to Jump and Strafe Left, to jump and strafe left at the same time.
    - The red warning for assigning the same key to multiple key binds is changed to yellow.
  - Added a Spectator category in the key binds screen, alongside the pre-existing Highlight Players key bind.
  - The spectator hotbar menu key can now be rebound.
- Particles
  - dragon_breath now optionally takes a power parameter (float, default 1.0), which is multiplied onto its initial velocity, after all randomness.
  - instant_effect and effect now optionally take power (float, default 1.0) and color (rgb, default 0xFFFFFF) parameters.
  - flash now requires a color parameter (argb).
- Rendering
  - Particles outside of players view are not rendered anymore, which provides a performance improvement in some cases.

  - The version is now 68.0.
- Server Code of Conduct
  - Formatting codes are now stripped from code of conduct files.

  - The following unused shaders have been removed:

    - core/position_color_lightmap.fsh
    - core/position_color_tex_lightmap.vsh
    - core/position_color_tex_lightmap.fsh
  - Minor change to uv calculations in the minecraft_sample_lightmap function in the core/terrain.vsh program.
- UI
  - Double-clicking a word in edit box now selects it.
- World border
  - The world border is now dimension-specific.
    - This means that each dimension can have its own world border size, position, etc.
