Minecraft:Java Edition 23w43a

23w43a is the fourth Minecraft:snapshot for Minecraft:Java Edition 1.20.3, released on October 25, 2023,<ref>Template:Snap</ref> which adds copper and tuff family blocks under experimental features, introduces a new look for bats, adds Template:Cmd command, and fixes bugs.

Additions

Command format

Template:Cmd

• A new administrative and debugging command which allows the player to control the ticking flow and measure the performance of the game.
  • Requires elevated permissions (admins and above), and so it is not by default available in Minecraft:command blocks and Minecraft:data packs.
  • Syntaxes:
    • Template:Cmd
      • Outputs the current target ticking rate, with information about the tick times performance.
    • Template:Cmd
      • Sets a custom target ticking rate to the specified value. The value rate must be greater than 1.0 and lower than 10000.0.
    • Template:Cmd
      • Freezes all gameplay elements, except for Minecraft:players and any Minecraft:entity a player is Minecraft:riding.
    • Template:Cmd
      • Only works when the game is frozen. It runs the game for the specified number of ticks and then freezes the game again.This allows to step through the game a set amount of ticks at a time.
    • Template:Cmd
      • Stops the current stepping process, and re-freezes the game.
    • Template:Cmd
      • Unfreezes the game and resumes all gameplay elements.
    • Template:Cmd
      • Runs the game while ignoring the set ticking target rate for the specified number of ticks. At the end of the sprint, the game resumes the previous ticking target and display performance information about the tick times while sprinting.
    • Template:Cmd
      • Stops the current Template:Cmd, and resumes the previous ticking target.

Changes

Blocks

Minecraft:Jigsaw block

• Added two new input fields in the edit screen.
  • Selection priority
    • When the parent piece is being processed for connections, this controls the order in which this jigsaw block attempts to connect to its target piece.
    • Jigsaws are processed in descending priority order and randomly within the same priority.
  • Placement priority
    • When this jigsaw block connects to a piece, this is the order in which that piece is processed for connections in the wider structure.
    • Pieces are processed in descending priority order with the default insertion order breaking ties within the same priority.
  • This functionality has been added to support the ability for jigsaw structures to generate branches in a depth-first order, as well as give finer control over ordering of connections.
  • All existing jigsaw blocks default their selection and placement priority to 0, resulting in the same behavior as before these two configurable values were introduced.

Items

Minecraft:Arrows

• Special arrows, such as Minecraft:spectral arrows, no longer revert to regular arrows when shot and picked up.

Minecraft:Ender pearl

• Thrown ender pearls produce a teleportation sound on impact.

Minecraft:Bat

• Their model, animations, and texture have been updated.

Additions

Blocks

Template:Animate Minecraft:Chiseled copper

• Have 8 variants in 4 oxidation levels, waxed or not waxed.
• Can be crafted both in Minecraft:crafting table and Minecraft:stonecutter:
  • When in crafting table, consume 2 Minecraft:cut copper slabs from the same type, resulting in 1 chiseled copper with the same type.
  • When in stonecutter, consume 1 Minecraft:block of copper, resulting in 4 chiseled copper from the same type.

Template:Animate Minecraft:Copper bulb

• A light-emitting block that can toggle its light emission through redstone pulses.
• Have 8 variants in 4 oxidation levels, waxed or not waxed.
• Can be crafted in crafting table with a cross pattern, by 3 blocks of copper from the same type, 1 Minecraft:blaze rod in the center slot, and 1 Minecraft:redstone dust in the bottom slot, resulting in 1 copper bulb with the same type.
• They emit less light the more oxidized they are. From less oxidized to most oxidized, they emit block light levels of 15, 12, 8, and 4, respectively.
• While powered by a redstone signal, a redstone crystal in the center of them glows.
• They have following properties:
  • Only toggle their light on or off when receiving a redstone pulse. Their state isn't changed if the source of the redstone pulse is removed.
  • When the light is on, redstone comparators read a signal strength of 15.
  • Don't conduct redstone power.

• Have 8 variants in 4 oxidation levels, waxed or not waxed.
• Works like wooden doors in that they can be opened and closed by the player as well as redstone.

Template:Animate Minecraft:Copper grate

• A new type of decorative block unique to the copper family.
• Have 8 variants in 4 oxidation levels, waxed or not waxed.
• Can be crafted both in crafting table and stonecutter:
  • When in crafting table, consume 4 blocks of copper from the same type in rhombic pattern, resulting in 1 copper grate with the same type.
  • When in stonecutter, consume 1 block of copper, resulting in 4 copper grate from the same type.
