• Added Template:Cd
  • Contains fluids satisfy adjacency support requirements for Minecraft:sugar cane.
• Added Template:Cd fluid tag to define which fluids a Minecraft:bubble column can occupy with water as default.

Minecraft:Time markers

• Time markers assign a particular name to a specific (optionally repeating) point in time for a specific world clock. Time markers replace the previously predetermined names that could be used by Template:Cmd, for example Template:Cd or Template:Cd.
• Time markers will exist within the context of a specific world clock. This means that even though the different time markers are defined by different Timelines, only one Time Marker can exist with a particular id for a particular world clock. It also means that two world clocks can have a time marker with the same name.
  • Built-in uses of time markers
    • Some time markers are used to drive Vanilla game behavior. Usually, they are configured to not show up in Template:Cmd commands.
      • Template:Cd - the time to advance the dimension's default clock to when players in that dimension wake up after sleeping.
      • Template:Cd - the time of the dimension's default clock at which the random chance for a zombie village siege to occur should be evaluated.

Minecraft:World clocks

• Each world clock contains an internal time that increases every tick. A world clock can be defined in data packs under the Template:Cd registry (i.e. found under data/<namespace>/world_clock/<id>.json)
• A world clock can be paused or resumed, and the time of the clock can be changed or queried, using the Template:Cmd command.
  • This allows different dimensions to have different clocks.
• Format: object with no fields

Changes

Blocks

Minecraft:Dispenser

• Minecraft:Spawn egg without a [[Minecraft:data component#entity_data|Template:Cd]] component are dropped as an item. Previously, the dispenser failed to activate.

Minecraft:Tripwire

• The tripwire texture is now rendered as alpha cutout instead of transparent.
  • In other words, the texture is now opaque.

Command format

Template:Cmd

• Both arguments can now be omitted.
  • The entity selector will be Template:Cd if omitted
  • Which hand to swing will be Template:Cd if omitted

Template:Cmd

• The Template:Cmd command is now based on world clocks.
  • A clock can be optionally specified as an input for the time command with Template:Cmd.
  • If the clock is not specified (Template:Cmd as before), the default clock for the dimension is used.
• The return value (e.g. from Template:Cmd) from the Template:Cd and Template:Cd subcommands is now the total elapsed ticks of the clock instead of the current time of day.
• Syntax:
  • Template:Cmd - sets the total elapsed ticks of the clock.
  • Template:Cmd - advances the clock forward to the next occurrence of the time marker..
    • For the Template:Cd clock, the available time markers are: Template:Cd, Template:Cd, Template:Cd, and Template:Cd
  • Template:Cmd - adds ticks to the clock, can be a negative or a positive number.
  • Template:Cmd - pauses the clock.
  • Template:Cmd - resumes the clock.
  • Template:Cmd - displays and returns the current number of ticks within the timeline's period.
  • Template:Cmd - displays and returns the number of times the timeline's period has repeated.
  • Template:Cmd - displays and returns the total elapsed ticks of the clock.
  • Template:Cmd - as before, the total elapsed ticks within the world (unaffected by changes made to clocks using Template:Cmd).

Items

Minecraft:Bundles

• Now supports a [[Minecraft:data component#bundle_container|Template:Cd]] component with a weight greater than 2³¹-1, equivalent to 2³¹-1 stacks.
  • Previously, the component was removed when the limit was exceeded.
  • A bundle exceeding this limit is shown as full, however, when attempting to empty it, add a new item, or view the tooltip, it still appears empty.

Minecraft:Item stack

• Now, in many cases, it is treated as empty if it has conflicting data, such as having a count greater than [[Minecraft:Data_component#max_stack_size|Template:Cd]], or having Template:Cd greater than one along with [[Minecraft:Data_component#max_damage|Template:Cd]].
  • When mining a Minecraft:shulker box containing an item stack with a conflicting data, it will treat the item as Template:Cd in the tooltip, and placing it in a block the item stack will be removed.
  • Shooting an Minecraft:arrow with a conflicting data using a Minecraft:crossbow will not be a project.
  • Template:Control a Minecraft:bundle to remove an item stack with a conflicting data, no items will be dropped. Viewing the tooltip of the bundle, the game try render an empty stack, causing the game to crash.<ref>Template:Bug</ref>
  • Item stacks with conflicting data can still be placed in Minecraft:chests and in the Minecraft:inventory.
