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 /time set, for example day or night.
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 /time commands.
    - minecraft:wake_up_from_sleep - the time to advance the dimension's default clock to when players in that dimension wake up after sleeping.
    - minecraft:roll_village_siege - the time of the dimension's default clock at which the random chance for a zombie village siege to occur should be evaluated.

Trade sets

What trades are unlocked by villager professions are now determined using deterministic random sequences, like loot drops and barter loot.
Present in the trade_set folder, they are groupings of trades offered by villagers and wandering traders.
Currently only hardcoded ones are available in <profession>/level_<level> for villagers, as well as wandering_trader/buying, wandering_trader/special, wandering_trader/common for wandering traders.
Entry Format:
- trades, a villager trade id, list of namespaced villager trade IDs, or hash-prefixed villager trade tag representing the trades that are part of this trade set.
- amount, a number provider representing the amount of trades to be generated from this set when used.
  - If the generated number is greater than the number of available trades then it will only generate until all trades have been used once, unless allow_duplicates is set to true
- allow_duplicates, a boolean representing if the trade set can use the same villager trade multiple times to generate trades.
  - Defaults to false
- random_sequence, an optional named random sequence that determines which trades are generated.
  - Defaults to a non-deterministic random sequence.
- An example trade set offering 2 trades from the #minecraft:armorer/level_1 tag, allowing duplicates.

{
 "amount": 2.0,
 "trades": "#minecraft:armorer/level_1",
 "random_sequence": "minecraft:trade_set/armorer/level_1",
 "allow_duplicates": true
}

Villager Trade tags

Added several tags representing groups of villager trades from which villagers and wandering traders derive their trading pools.
- Villagers have the following tags representing each profession and level of trade in the format: #<profession>/level_<level>, up to level 5.

- Wandering Traders have the following tags: #wandering_trader/buying, #wandering_trader/special, #wandering_trader/common.

World clocks

Each world clock contains an internal time that increases every tick. A world clock can be defined in data packs under the world_clock 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 /time command.
- This allows different dimensions to have different clocks.
Format: object with no fields
Added minecraft:the_end world clock to the End dimension.
- It now controls End flashes.

Changes

Blocks

Dispenser

Spawn egg without a entity_data component are dropped as an item. Previously, the dispenser failed to activate.

Item stack

Now, in many cases, it is treated as empty if it has conflicting data, such as having a count greater than max_stack_size, or having max_stack_size greater than one along with max_damage.
- When mining a shulker box containing an item stack with a conflicting date, it will treat the item as Air x0 in the tooltip, and placing it in a block the item stack will be removed.
- Shooting an arrow with a conflicting date using a crossbow will not be a project.
- Using a bundle to remove an item stack with a conflicting date, no items will be dropped.

Command format

/time

The /time command is now based on world clocks.
- A clock can be optionally specified as an input for the time command with /time of <clock> ....
- If the clock is not specified (/time ... as before), the default clock for the dimension is used.
The return value (e.g. from /execute store) from the set and add subcommands is now the total elapsed ticks of the clock instead of the current time of day.
Syntax:
- /time [of <clock>] set <time> - sets the total elapsed ticks of the clock.
- /time [of <clock>] set <timemarker> - advances the clock forward to the next occurrence of the time marker..
  - For the minecraft:overworld clock, the available time markers are: day, noon, night, and midnight
- /time [of <clock>] add <time> - adds ticks to the clock, can be a negative or a positive number.
- /time [of <clock>] pause - pauses the clock.
- /time [of <clock>] resume - resumes the clock.
- /time [of <clock>] query <timeline> - displays and returns the current number of ticks within the timeline's period.
- /time [of <clock>] query <timeline> repetitions - displays and returns the number of times the timeline's period has repeated.
- /time [of <clock>] query time - displays and returns the total elapsed ticks of the clock.
- /time query gametime - as before, the total elapsed ticks within the world (unaffected by changes made to clocks using /time).

Data pack

The pack format version is now 98.0.
Villager inventory slots can now be accessed using mob.inventory.*; villager.* has been removed.

Debug screen

The looking_at_block and looking_at_fluid debug entries no longer show tags.

- looking_at_fluid_tags
- looking_at_entity_tags
Renamed debug entries:
- looking_at_block -> looking_at_block_state
- looking_at_fluid -> looking_at_fluid_state

Dimension types

Added the field default_clock: optional world clock ID.
- Specifies the default clock that will be used for the /time command.
  - If a default clock is specified, the time command requires an explicit clock argument.
- Also specifies the clock to which minecraft:wake_up_from_sleep and minecraft:roll_village_siege time markers apply.
  - If not specified, those time markers will never apply in that dimension.

Enchantment definition

The post_piercing_attack component no longer only works for a player if that player has a certain food level.

Entity data

The current_explosion_impact_pos and current_impulse_context_reset_grace_time fields from players have been added to all mobs and the armor stand.
The ignore_fall_damage_from_current_explosion field on players has been removed.

Environment attribute

Updated the gameplay/turtle_egg_hatch_chance environment attribute to have a default value of 0.002.

Game rules

The game rules screen is now accessible in-game through a new World Options screen in the pause menu.
A search bar has been added to the top of the game rules screen, both in-game and in the world creation menu.

Game Tests

Replaced time_of_day with clock_time.
- Added a new required field clock: world clock ID, the clock within which to set time (from the existing time field).

Lightmap algorithm

The algorithm that maps block and sky light levels to how bright things appear on screen has been fully rewritten.
A new algorithm that is supposed to mostly provide the same overall results as previous one, but:
- It is simpler and more straightforward, and fixes multiple issues of the previous one.
- The darkness effect and world darkening effect of the Wither fight now works the same way in all dimensions.
- The night vision effect now simply adds ambient light instead of scaling the resulting colors.
  - It means that fully dark areas no longer look brighter than areas lit by block or sky light.
- Other aspects of the algorithm such as block light tint, ambient light color and night vision color are now data-driven through environment attributes.

Lightmap shader

The lightmap.fsh shader was significantly modified.
- The LightmapInfo uniform now has two new fields:
  - BlockLightTint
  - NightVisionColor
- The AmbientLightFactor field was removed, its value is now premultiplied into AmbientColor
- The DarkenWorldFactor was renamed to BossOverlayWorldDarkeningFactor
Text and items rendered in UI now use a separate 1x1 white lightmap texture, so the lightmap shader does not always have to keep the 15, 15 pixel purely white.

Loot functions

minecraft:enchant_with_levels

minecraft:enchant_randomly
- Now also takes the following field:
  - include_additional_cost_component - optional boolean representing if a minecraft:additional_trade_cost component should be added to the item based on the cost of the enchantment.
    - Defaults to false
    - The value is determined by the value selected by levels or its default value using the following formula: $2 + r a n d o m (0, 5 + l e v e l * 10) + 3 * l e v e l$

minecraft:set_random_dyes
- No longer works only for items in #dyeable tag.

Mob variant definitions
