Time for another content preview for Itematic. In this preview version the tool item behaviour was expanded slightly.

Changes

Item Behaviour Components

minecraft:tool

• Made changes to the tool rules:
  • Added an optional item field, which is an item predicate that checks the item stack that is used as a tool.
  • Made the blocks field optional.
  • Allowed 0 for the tool speed instead of it being strictly positive.
• These changes were made in favour of expanding the behaviour of the preserve_item field in minecraft:damageable as this can be controlled more precisely than a simple boolean and keeps the mining behaviour in this behaviour component.
  • Note that this behaviour can still be combined with the preserve_item field to prevent the item from breaking and from being used as a tool altogether, which is likely preferred as an item stack may not necessarily be damaged by exactly one point.

An example based on the minecraft:iron_pickaxe item that sets the mining speed to 0 when the durability is 1:

{
  "minecraft:tool": {
    "rules": [
      {
        "item": {
          "predicates": {
            "minecraft:damage": {
              "durability": 1
            }
          }
        },
        "speed": 0.0
      },
      {
        "blocks": "#minecraft:incorrect_for_iron_tool",
        "correct_for_drops": false
      },
      {
        "blocks": "#minecraft:mineable/pickaxe",
        "correct_for_drops": true,
        "speed": 6.0
      }
    ]
  }
}
