Tag Extensions

LibCD adds the ability for tag JSONs to contain a libcd block which uses Conditions for partial tag loading. Tag JSONs without libcd blocks will not be affected.

Elements

• "replace": takes a single object for a Condition. If the Condition is true, the LibCD block will replace all tag entries before this tag JSON. Entries in this tag JSON's normal values block will still be added if the LibCD replace element is true. Optional.
• "entries": takes an array of objects. Each object contains the following keys:
  • "when": takes an array of Condition objects.
  • "values": exactly like the standard tag JSON values element. These values will only be appended if the when for this entry evaluates to true.

Example

For a tag at the data pack location data/c/tags/items/potatoes.json:

{
    "replace": false,
    "values": [
        "minecraft:potato",
        "minecraft:poisonous_potato"
    ],
    "libcd": {
        "replace": { "libcd:dev_mode": true },
        "entries": [
            {
                "when": [
                    { "libcd:mod_loaded": "lil-tater" }
                ],
                "values": [
                    "lil-tater:lil_tater",
                    "lil-tater:lil_tater_tot",
                    "lil-tater:compressed_tater_tot",
                    "lil-tater:irritated_tater",
                    "lil-tater:drowned_tater"
                ]
            }
        ]
    }
}
