Modify (Item Action Type)

Applies an item modifier to the item stack.

Type ID: apoli:modify

Fields

Examples

"item_action": {
    "type": "apoli:modify",
    "modifier": "example:stuff"
}

This applies the example:stuff item modifier to the stack. The item modifier itself looks like this:

{
    "function": "minecraft:set_lore",
    "entity": "this",
    "lore": [
        {
            "text": "Hello, I'm a custom lore line for your item :]",
            "color": "light_purple",
            "italic": false
        }
    ]
}

The loot context the modifier runs in supplies origin (the holder's position), tool (the stack being modified) and this_entity (the holder). Every other loot parameter is missing, so a function that reads one (minecraft:copy_state, or anything that needs block_entity) fails. Functions that swap the item outright, like minecraft:furnace_smelt, only work where Apoli can replace the whole stack, which is inside apoli:item_on_item. Everywhere else, the new item's components and count are copied onto the existing stack, so the item itself stays the same.
