Attribute Loot Condition

🪄 About the Modification

This mod introduces a new type of condition for loot tables (so-called predicates), allowing to configure dropped loot based on entity characteristics.

Works well with modifications that implement mob attribute scaling, such as RpgDifficulty and L2 Hostility.

⚙️ Parameter Configuration

The default configuration file looks as follows:

(config/attribute_loot_condition.json)

{
  "attributeWeights": [
    {
      "attribute": "minecraft:generic.max_health",
      "weight": 1.0
    },
    {
      "attribute": "minecraft:generic.armor",
      "weight": 1.0
    },
    {
      "attribute": "minecraft:generic.armor_toughness",
      "weight": 1.0
    },
    {
      "attribute": "minecraft:generic.attack_damage",
      "weight": 1.0
    }
  ]
}

The elements in this array determine weight coefficients for various characteristics.

You can configure additional attributes, not limited to only these four.

📜 Usage Example

In JSON format, comments are not allowed, but in this case they are added for clarification.

Datapack:

data/minecraft/loot_tables/entities/zombie.json

{
    "pools": [
        {
            "rolls": 1,
            "entries": [
                {
                    "type": "item",
                    "name": "minecraft:apple"
                }
            ],
            "conditions": [
                {
                    "condition": "attribute_loot_condition:attribute_weighted_sum",
                    "entity": "this",
                    "min": 20,
                    "max": 0  // Value not greater than 0 cancels this check
                }
            ]
        }
    ]
}

After loading this datapack, when a player kills a zombie, the game calculates the weighted sum of the zombie's maximum health, armor, armor toughness, and damage. If this sum is at least 20, then the condition is considered fulfilled.
