Baby mobs

Rabbit

• Idle animation is now disabled while they are leashed.

Graphical

• Improved how scrollable screen content is displayed in Ore UI menu screens on devices with notches, rounded corners, or safe zones applied. Content now smoothly scrolls beneath the safe area instead of being cut off.

AI Goals

• Made the schema for minecraft:behavior.jump_around_target stricter when parsing, now will fail to load an entity json that has invalid data in versions 1.26.20 and newer. Float Range fields valid_distance_to_target and landing_distance_from_target now only accepts an object with min and max values. Other formats will fail to parse.
• Made the schema for minecraft:behavior.jump_to_block stricter when parsing, now will fail to load an entity json that has invalid data in versions 1.26.20 and newer. Float Range field cooldown_range now only accepts an object with min and max values. Other formats will fail to parse.

  • minecraft:behavior.flee_sun

General

Items
