  • The Copper, Iron, and Gold blocks were moved to match the Raw versions ordering
  • The Copper Doors were moved to all the other Doors
  • The Copper Trapdoors were moved to the group with all the other Trapdoors, this is not a trap
  • Copper Blocks and Copper Grates are now sorted by Block type then by Oxidation level, instead of Oxidation level then Block type

Technical Updates

Block

• Added content warning when “carried_textures” or “blockshape” are incorrectly written in blocks.json

Components

• Renamed the “minecraft:lookat” component to “minecraft:looked_at” to better reflect its functionality
  • Its “look_event” field was also renamed to “looked_at_event”
  • Its “look_cooldown” field was also renamed to “looked_at_cooldown”
• Expanded the “minecraft:looked_at” component functionality with the addition of six new [Beta] fields:
  • “find_players_only” restricts the search for entities looking at the owner entity to Players only, ensuring that the closest Player satisfying the specified “filters” is selected
  • “look_at_locations” defines the parts of the owner entity that are targeted for being looked at
    • For these parts, a line-of-sight check is performed to ensure no blocks obstruct the view
    • Supported values are “head”, “body”, and “feet”
  • “not_looked_at_event” specifies the event to trigger when no suitable entity is looking at the owner entity
  • “field_of_view” defines the width of the field of view, in degrees, for entities looking at the owner entity:
    • If “scale_fov_by_distance” is set to true, this value corresponds to the field of view at a distance of one block between the entities
  • “scale_fov_by_distance” determines if the field of view narrows as the distance between the owner entity and the entity looking at it increases
    • This ensures that the width of the view cone at the owner entity position remains relatively constant, regardless of distance
  • “line_of_sight_obstruction_type” defines which block shape is considered when checking for line-of-sight obstructions
    • Supported values are “outline,” “collision,” and “collision_for_camera”
  • Moreover, “set_target” now supports three different values:
    • “never”, looking entities are never set as targets, but events are emitted
    • “once_and_stop_scanning”, the first detected looking entity is set as target, but scanning and event emission is suspended if and until the owner entity has a target
    • [Beta] “once_and_keep_scanning”, the first detected looking entity is set as target, but scanning and event emission continues
  • All these fields are planned to be taken out of [Beta] and fully released at a later date

Editor

• Added an initial Editor Settings panel with options for ‘Show Invisible Blocks’ and ‘Show Chunk Boundaries’

Entity Event Responses

Feature

  • Floating point numbers are no longer accepted where an integer is expected
