Record Class SimpleTrade

java.lang.Object
java.lang.Record
dev.architectury.registry.level.entity.trade.SimpleTrade
All Implemented Interfaces:
net.minecraft.world.entity.npc.VillagerTrades.ItemListing
public record SimpleTrade(net.minecraft.world.item.ItemStack primaryPrice, net.minecraft.world.item.ItemStack secondaryPrice, net.minecraft.world.item.ItemStack sale, int maxTrades, int experiencePoints, float priceMultiplier) extends Record implements net.minecraft.world.entity.npc.VillagerTrades.ItemListing
This class is the easiest implementation of a trade object. All trades added by vanilla do have custom classes like VillagerTrades.EmeraldForItems, but they aren't accessible.

Instead of widening the access of those classes or recreating them, this class was added to serve a basic trading implementation. To register a trade, just call TradeRegistry.registerVillagerTrade(net.minecraft.world.entity.npc.VillagerProfession, int, VillagerTrades.ItemListing...) or TradeRegistry.registerTradeForWanderingTrader(boolean, VillagerTrades.ItemListing...).

      Parameters:
      primaryPrice - The first price a player has to pay to get the 'sale' stack.

      sale - The ItemStack which a player can purchase in exchange for the two prices.
      maxTrades - The amount of trades one villager or wanderer can do. When the amount is surpassed, the trade can't be purchased anymore.
      experiencePoints - How much experience points does the player get, when trading. Vanilla uses between 2 and 30 for this.
      priceMultiplier - How much should the price rise, after the trade is used. It is added to the stack size of the primary price. Vanilla uses between 0.05 and 0.2.
