Minecraft Snapshot 20w18a
A Minecraft Java Snapshot
In this snapshot we've made some changes to redstone wire and fixed a bunch of bugs.
Changes in 20w18a
- Redstone wire changes
- The target block now conducts redstone signals
The blockstate, rendering and behavior of redstone wire are more in line with each other. Redstone will provide power to blocks on all sides it shows a visual connection to, and not do so on those sides without a visual connection.
- A single redstone wire is now represented as a cross.
- A wire on top of a block, which is redirected from below, will power the sides it is redirected to now. E.g. a fence gate above the redirecting wire will be powered.
- Wires that redirect upwards to wires on non-conductive blocks used to only be redirected visually. Now this redirection applies to their behavior as well.
- A wire that is redirected to go over a block will now always provide power to the block. This is most noticeable when the wire has signal strength 1.
Technical Changes in 20w18a
- Added a enable-status option to the server.properties file which if set to false will suppress replies to status requests from clients. This makes the server appear offline in the multiplayer screen
- Added control over how much entity data a server sends to clients
- Advancement system changes
It is now possible to control at what range the server sends data about entities to clients.
- Added an entity-broadcast-range-percentage server property controlling how close entities need to be before being sent to clients. Higher values means entities are visible further away from players but cause more network traffic. Specifies percentage of default value, so for example 50 specifies half of the default range.
- Added player check to every trigger (except impossible)
- Entity checks in triggers can now use loot table condition syntax
Extended entity checks
Entity checks in triggers can now use loot table condition syntax.
is now equivalent to:
Note 1: Like in loot tables, all conditions in top level array must be met for whole condition to trigger.
Note 2: To access new functionality, top level element must be JSON array. JSON object are interpreted as old notation.
Full list of extended triggers:
- New field player in every trigger
- bred_animals - parent, partner, child
- channeled_lightning - victims
- cured_zombie_villager - zombie, villager
- fishing_rod_hooked - entity
- killed_by_crossbow - victims
- player_killed_entity - entity
- entity_killed_player - entity
- player_hurt_entity - entity
- summoned_entity - entity
- tame_animal - entity
- target_hit - projectile
- villager_trade - villager
Miscellaneous trigger changes
- Due to addition of player, existing contents of location, slept_in_bed, hero_of_the_village, voluntary_exile can now be placed in location field instead of top-level object. Old syntax is still supported, but depreciated.
