Assigning Powers to Items

Via Data Component

Powers can be granted to a player based on what items they are wearing or holding, using the palladium:powers data component on an item.

The component maps equipment slots to one or more power IDs. The power is active as long as the item is in the matching slot.

addon/mypack/item/power_ring.json

{
  "type": "minecraft:item",
  "properties": {
    "components": {
      "palladium:powers": {
        "mainhand": "mypack:super_strength",
        "offhand": "mypack:super_strength"
      }
    }
  }
}

addon/mypack/item/spider_suit.json

{
  "type": "minecraft:armor",
  "armor_material": "mypack:spider_silk",
  "armor_type": "chestplate",
  "properties": {
    "components": {
      "palladium:powers": {
        "chest": ["mypack:wall_crawling", "mypack:spider_sense"]
      }
    }
  }
}

For a full description of the component format, valid slot keys, and how to target multiple slots at once, see the Data Components page.

Suit Sets

Powers can also be granted when a player is wearing a complete suit set. Unlike the component approach above, this checks that all pieces of the set are worn at the same time.

These files are datapack content, placed in the data directory:

data/<namespace>/palladium/suit_set_power/<id>.json

Field	Type	Description
suit_set	Identifier	The registry ID of the suit set.
power	HolderSet	The powers to grant. Can be a tag (e.g. #mypack:spider_powers) or a list of IDs.

The power field is a homogeneous HolderSet, so a plain array can only contain direct IDs or a single tag, not both mixed. To combine them, use "type": "neoforge:or" as described on the Data Components page.

Examples

Single power ID:

data/mypack/palladium/suit_set_power/iron_spider_powers.json

{
  "suit_set": "mypack:iron_spider",
  "power": "mypack:wall_crawling"
}

Power tag:

data/mypack/palladium/suit_set_power/iron_spider_powers.json

{
  "suit_set": "mypack:iron_spider",
  "power": "#mypack:iron_spider_powers"
}

Multiple power IDs:

data/mypack/palladium/suit_set_power/iron_spider_powers.json

{
  "suit_set": "mypack:iron_spider",
  "power": ["mypack:wall_crawling", "mypack:web_shooting"]
}
