- New selector parameter
predicateallows applying custom predicates, defined in thepredicatesdirectory of a data pack.
- Loot table predicates can now be defined in separate files and used for entity selectors and in execute if command.
- Added new parameters to the
location_checkcondition.- [Int] offsetX, [Int] offsetY, [Int] offsetZ – optional offsets to location.
- Added
reference.- Includes condition defined in predicates directory of data pack, selected with name parameter.
- Added
time_checkcondition.- Checks time of day.
- [Int] value – range of accepted values.

- For example,
recipes– map of recipe IDs. Boolean value tells if it should or should not be known to player.advancements– map of advancement IDs. If value is a boolean, checks if advancement is done. If value is an object, checks completion of criterions.
- Entity predicate now accepts
teamfield, which matches team name.
Location predicate
- Predicate now accepts
blockandfluidsub-predicate. - Predicate now accepts the
