Trader trades

Sponge trader offers use vanilla's data-driven trade system. There are three layers:

1. Trades (villager_trade): one offer each, such as "5 emeralds for a sponge".
2. Trade tags (tags/villager_trade/sponge_trader/): the pool of trades for one trader and one tier.
3. Trade sets (trade_set/sponge_trader/): how many offers the trader picks from a pool.

Each trader uses three trade sets: <element>_buying, <element>_common and <element>_uncommon, where <element> is water, lava, snow or fire.

WARNING

Trades and trade sets are loaded when the world starts, so restart the world after changing them. A trader keeps the offers it rolled when you first talked to it, so the changes only show on newly spawned traders.

Trade files

data/moresponge/villager_trade/sponge_trader/emerald_sponge.json:

{
  "wants": {
    "id": "minecraft:emerald",
    "count": 5
  },
  "gives": {
    "id": "minecraft:sponge"
  },
  "max_uses": 2,
  "reputation_discount": 0.05
}

Field	Description
wants	The item the player pays: id and count.
additional_wants	Optional second item the player pays.
gives	The item the player gets.
max_uses	How many times the offer can be used. Defaults to 4.
reputation_discount	Price multiplier from reputation. The mod uses 0.05.
xp	Villager experience for the trade. Defaults to 1.

Other vanilla fields, such as merchant_predicate and given_item_modifiers, also work. The mod's files are named emerald_<item> for things the trader sells and <item>_emerald for things it buys.

Trade tags

data/moresponge/tags/villager_trade/sponge_trader/water_common.json:

{
  "values": [
    "moresponge:sponge_trader/emerald_sponge",
    "moresponge:sponge_trader/emerald_wet_sponge",
    "moresponge:sponge_trader/emerald_compressed_sponge",
    "moresponge:sponge_trader/emerald_wet_compressed_sponge"
  ]
}

A tag in your datapack adds to the mod's list. Set "replace": true to use only your own list.

Trade sets

data/moresponge/trade_set/sponge_trader/water_uncommon.json:

{
  "amount": 1,
  "trades": "#moresponge:sponge_trader/water_uncommon",
  "random_sequence": "moresponge:trade_set/sponge_trader/water_uncommon"
}

Field	Description
amount	How many offers to pick from the pool.
trades	The trade tag to pick from (or a list of trade ids).
allow_duplicates	Whether the same trade can be picked twice. Defaults to false.
random_sequence	Optional id for the random sequence.

Example: sell a 5x sponge more often

Change water_uncommon.json to pick two offers:

{
  "amount": 2,
  "trades": "#moresponge:sponge_trader/water_uncommon"
}
