Commands
clone
The clone command now supports specifying the source and target dimensions. New syntax:
clone [from <sourceDimension>] <begin> <end> [to <targetDimension>] <destination> ...
Parameters:
- sourceDimension: id of dimension to clone from
- targetDimension: id of dimension to clone to
data
New source available:
- string <entity|block|storage> [path] [start] [end] - reads a value as text, resulting in a string value
New arguments:
- start: Index of first character to include at the start of the string
- end: Index of the first character to exclude at the end of the string
execute
execute if|unless
New conditions available for the execute if|unless sub-command:
- execute if|unless loaded <pos> - checks if the position given is fully loaded (in regard to both blocks and entities)
- execute if|unless dimension <dimension> - checks if the execution is in a matching dimension
Parameters:
- pos: Block position to check
- dimension: A dimension id
execute on
New execute sub-command for selecting entities based on relation to the current executing entity:
- execute on <relation>
Relations:
- vehicle - entity that the executing entity is riding
- passengers - all entities directly riding the executing entity (no sub-passengers)
- controller - entity that is controlling the executing entity (for example: first passenger in a boat)
- owner - owner of the executing entity, if it is a tameable animal (like cats, wolves or parrots)
- leasher - entity leading the executing entity with a leash (might be a leash knot in case of being attached to a fence)
- target - attack target for the executing entity
- attacker - last entity that damaged the executing entity in the previous 5 seconds
If the relation is not applicable to the executing entity or there are no entities matching it, selector returns zero elements.
title
- All time arguments to title times are now time durations and work with t, s and d suffixes
weather
- The duration of the weather change now matches the game's regular weather cycle if not specified
- The duration parameter is now a time duration in ticks and works with t, s and d suffixes
- To retain existing functionality, you need to add an s suffix to pre-existing commands
ride
New command to allow entities to start or stop riding other entities
Syntax:
- ride <target> mount <vehicle>
- Makes a single target mount a single vehicle
- The command will fail if:
- vehicle is a player
- target is already riding a vehicle
- target and vehicle are the same entity
- vehicle is already a passenger (direct or indirect) of target
- ride <target> dismount
- Dismounts target from any vehicle it is riding
- Fails if target is not riding anything
Game Rules
- Added commandModificationBlockLimit, controlling the maximum number of blocks changed in one execution of clone, fill and fillbiome
Chat components
Translation fallback
Added an optional fallback field to translate text components.
- The new field is a string that will be used in place of translation if it is missing
- If fallback is missing, the old behavior (i.e. using the key itself as the translation) is preserved
Experimental Features
Note block interaction
- Mob heads can now be placed on top of note blocks without sneaking
