Minecraft Preview 1.20.0.20

A Minecraft Preview Changelog

Do you tend to play Minecraft by spawning in and thwacking the first hostile mob you see? Then I have good news for you! You can now protect yourself in style with a new feature: the customizable shield. This parity feature not only brings shield banner customization to Minecraft: Bedrock Edition, but gives you a very fashionable (if somewhat flammable) defence tool. Just combine your shield with your favorite banner, and away you go. There are also new potions colors (ooo, distinguishable!), new sniffer breeding mechanics (ooo eggs!) and even a brand-new seed for your newly de-experimentified sniffer friends to seek out: the pitcher pod! As always, don’t forget to send us all your feedback and ideas at aka.ms/MC120Feedback and report any bugs to bugs.mojang.com.

Experimental Technical Updates

Add-Ons and Script Engine

    • Can parse PlacementDirection ("minecraft:placement_direction") BlockTrait (adds the "minecraft:cardinal_direction" BlockState and onPlayerPlace setter function)

Scripting

  • System Events
    • Further separation of events into distinct before* and after* handling, with some restrictions on the execution of state updates in a before event:
    • All before events moved from events into world.beforeEvents property. The "before" prefix has been removed. Functions that alter world state are prohibited in before event callbacks. Read-only methods and properties are allowed. Set methods are limited to the event object itself. Any use of restricted methods and properties will throw an exception.
    • For example, events.beforeWatchdogTerminate is now considered a "before" event. Functions that alter world state are prohibited in before event callbacks. Read-only methods and properties are allowed. Set methods are limited to the event object itself. Any use of restricted methods and properties will throw an exception
    • For example, events.scriptEventReceived is now considered an "after" event. After event callbacks are executed in a deferred manner. Using /scriptEvent something will queue script to execute at a later point
  • Renamed Scripting Events
    • Before Events renamed to *BeforeEvent and event signals renamed to *BeforeEventSignal
      • Example: BeforeItemUseEvent renamed to ItemUseBeforeEvent and BeforeItemUseEventSignal renamed to ItemUseBeforeEventSignal
