In this preview version a crash and visual bug regarding item holders was fixed and the block behaviour was expanded slightly.

Changes

Item Behaviour Components

minecraft:block

• Added a new optional field called passes:
  • Its value is a list of strings that allows its user to place a block given a certain context.
  • It replaces the need to use the minecraft:useable_on_block behaviour component.
  • The default value is ["block"].
  • Possible values:
    • block: Allows the user to place the block on another block.
    • fluid: Allows the user to place the block on a fluid.
  • Example from minecraft:lily_pad:

    {
      "block": "minecraft:lily_pad",
      "passes": [
        "fluid"
      ]
    }
    

Fixes

• Fixed a crash when dropping all items from an item holder.
• Fixed the item bar display for item holders with capacities that don't have a value of 1.
