Gummi Ships Data

Gummi Ship data is in the gummi_ships folder. Each file is a premade Gummi Ship that is turned into a Gummi Ship Blueprint item (shown in the creative Gummi tab and usable in the Gummi Hangar). The file id is the ship id, eg. gummi_ships/highwind.nbt is kingdomkeys:highwind.

These are NBT files, not JSON, and aren't written by hand. Build the ship in a Gummi Hangar and save it: saved ships are written to <game folder>/kingdomkeys/gummi_ships/<name>.nbt. Copy that file to data/<namespace>/gummi_ships/ in your data pack. Files bigger than 8 MB (uncompressed) are rejected.

Gummi Blueprint loot modifier

To make a ship blueprint appear in chest loot, add a NeoForge global loot modifier (in loot_modifiers, and listed in data/neoforge/loot_modifiers/global_loot_modifiers.json) of type kingdomkeys:gummi_blueprint:

(string) type: must be "kingdomkeys:gummi_blueprint".
(object array) conditions: vanilla/NeoForge loot conditions deciding which loot tables and how often, eg. neoforge:loot_table_id and minecraft:random_chance.
(string) ship: the id of the ship in the gummi_ships folder. If no data pack provides it, nothing is added and a warning is logged.

Example: loot_modifiers/highwind_end_city.json

{
  "type": "kingdomkeys:gummi_blueprint",
  "conditions": [
    {
      "condition": "neoforge:loot_table_id",
      "loot_table_id": "minecraft:chests/end_city_treasure"
    },
    {
      "chance": 0.25,
      "condition": "minecraft:random_chance"
    }
  ],
  "ship": "kingdomkeys:highwind"
}
