• All recipes now apply to wandering traders as well
• Added a new field merchant-type to check the entity type of the merchant (can be villager or wandering-trader)
• Certain villager fields now return null or 0 if the merchant is not a villager
  • Only recipe-count, world and inventory fields return sensible values, because wandering traders apparently have inventories

An example of using the new merchant-type field:

trader:
desc: Quintuple the amount you get from all wandering trader recipes
when:
merchant-type: wandering_trader
do:
set:
result.amount: "*= 5"
