Holder Condition (Item Condition Type)

Tests an entity condition against whoever is holding the stack. It fails when nothing is holding it, since an item on the ground or in a chest has no holder.

It connects an item context back to an entity, which lets an item condition depend on the person instead of the item.

Type ID: apoli:holder_condition (aliases apoli:holder and shappoli:holder_condition)

Fields

Field	Type	Default	Description
`entity_condition`	Entity Condition Type	required	The condition to test against the holder. `condition` is accepted as a legacy spelling.

Example

A cursed sword that only bites for people who aren't sneaking. Any sword gets three extra levels of Sharpness through apoli:modify_enchantment_level, but only while its holder stands up straight:

{
  "type": "apoli:modify_enchantment_level",
  "enchantment": "minecraft:sharpness",
  "item_condition": {
    "type": "apoli:all_of",
    "conditions": [
      { "type": "apoli:ingredient", "ingredient": { "tag": "minecraft:swords" } },
      {
        "type": "apoli:holder_condition",
        "entity_condition": {
          "type": "apoli:sneaking",
          "inverted": true
        }
      }
    ]
  },
  "modifier": { "operation": "add_base_early", "value": 3 }
}

Or make an item's use depend on the holder's resource:

{
  "type": "apoli:prevent_item_use",
  "item_condition": {
    "type": "apoli:holder_condition",
    "entity_condition": {
      "type": "apoli:resource",
      "resource": "vampire:blood",
      "comparison": "<=",
      "compare_to": 0
    }
  }
}
