Attribute (Power Type)

Modifies one or more attributes on the entity for as long as the power is held.

Type ID: apoli:attribute (type-alias: apoli:conditioned_attribute for back-compat with Apace’s packs)

In Apace’s Apoli, apoli:attribute did not accept a condition field; he later added apoli:conditioned_attribute as a parallel type that did. In this rewrite, condition is a property of every power (see Power JSON Format), so the same single type accepts conditions and the conditioned_attribute id is just an alias.

Fields#

Field	Type	Default	Description
modifier	Attribute Modifier	optional	A single modifier applied to its attribute.
modifiers	Array of Attribute Modifier	optional	Multiple modifiers applied to their respective attribute fields.
update_health	Boolean	true	When the modifier touches minecraft:generic.max_health, scale the player’s current health so their fill ratio is preserved.

At least one of modifier or modifiers must be present; the attribute field inside each modifier is required when the modifier is used by this power (otherwise the codec rejects it with a clear error).

Examples#

Single modifier:

{
    "type": "apoli:attribute",
    "modifier": {
        "name": "Max health increase",
        "attribute": "minecraft:generic.max_health",
        "value": 4,
        "operation": "addition"
    }
}

Multiple modifiers with a condition:

{
    "type": "apoli:attribute",
    "condition": {
        "type": "apoli:status_effect",
        "effect": "minecraft:strength"
    },
    "modifiers": [
        {
            "attribute": "minecraft:generic.attack_damage",
            "operation": "multiply_total",
            "value": 0.25
        },
        {
            "attribute": "minecraft:generic.movement_speed",
            "operation": "multiply_total",
            "value": 0.1
        }
    ]
}

Modifier driven by a resource value (links a vanilla attribute to a apoli:resource):

{
    "type": "apoli:attribute",
    "modifier": {
        "attribute": "minecraft:generic.attack_damage",
        "operation": "addition",
        "resource": "example:rage"
    }
}
