Minecraft Beta & Preview - 1.21.70.23

Components​

  • Added validation for asset references in components
    • Content errors will log missing references for the following fields:
      • item references
      • block reference in item component in "minecraft:block_placer"
      • loot table reference in block component "minecraft:loot"
  • The "entity_sensor" component's "find_players_only" field now functions correctly, properly restricting searches to Players only and affecting all subsensors

Dedicated Server​

  • Exposed two new parameters for dedicated server when in server-auth-with-rewind. These will make the server more strict on player positions. Look in server.properties for more information on what these do
    • server-authoritative-movement-strict default to false and can be set to true. Will affect Player position acceptance
    • server-authoritative-dismount-strict default to false and can be set to true. Will affect Player position when dismounting

Editor​

  • Added IButtonPanePropertyItem API for customizing button layouts
    • IPropertyPane.addButtonPane and IModalControlPane.addButtonPane API methods to create button pane items
  • Updated the mouse indicator for various tools to no longer linger after the app is suspended and resumed
  • Updated the maximum allowed line segments in Line Tool to 40 to address a crash

Entity Event Responses​

  • Added the "stop_movement" entity event response, which stops the entity's movement
    • The "stop_vertical_movement" field specifies whether vertical movement should be stopped
    • The "stop_horizontal_movement" field specifies whether horizontal movement should be stopped
    • This response does not stop navigation or prevent future movement
      • If that's the desired outcome, also remove the components responsible for that
  • Added the "set_home_position" entity event response, which sets the entity's home position to its current position
    • For this to have any effect, the entity must already have a "minecraft:home" component

Entity Events​

  • Added "first_valid" event type, it will evaluate every filter in order and execute the first valid one

Entity Filters​

  • The "in_clouds" entity filter now succeeds when an entity's bounding box intersects the cloud layer, rather than only when its bottom is within it

Jigsaw​

  • Fixed gaps from appearing between data-driven jigsaw structure pieces.

Mobs​

  • Added aquatic family-type for all aquatic mobs
  • Normal Minecart is no longer considered a mob
