We're back in action with another Snapshot! In this week's release we're making it possible to access game rules from the in-game pause screen, through the new world options button. On the data pack side of things, we're introducing a new concept of world clocks, which is an expansion of the work we did on timelines last year. For more information about world clocks and more, browse the full changelog below.
Happy mining!
day_count debug entry has been split from local_difficultyThe difficulty button in the pause menu has been replaced with a button leading to a new screen - World Options.
time command to work with World Clocks and Timelinestime_check condition to specify a World ClockWorld Clocks contain an internal time that increases every tick. They can be defined in data packs under the world_clock registry (i.e. found under data/<namespace>/world_clock/<id>.json)
time commandclock field: a World Clock ID, specifies which World Clock the timeline is tied tominecraft:overworld clock can be usedtime_markers field, an optional map between namespaced Time Marker IDs and either an int or a Time Marker object,ticks: int between 0 and period_ticks, the tick that the time marker marksshow_in_commands: optional boolean, specifies whether the Time Marker will show up in command suggestionsfalseTime 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.
Some Time Markers are used to drive Vanilla game behavior. Usually, they are configured to not show up in /time commands.
