Subject: [PATCH] Added PlayerTradeEvent
|
|
|
|
[Amendment: Alexander <protonull@protonmail.com>]
|
|
PlayerTradeEvent is used for player purchases from villagers and wandering
|
|
traders, but not custom merchants created via Bukkit.createMerchant(). During
|
|
discussions in Discord it was decided that it'd be better to add a new event
|
|
that PlayerTradeEvent inherits from than change getVillager()'s annotation to
|
|
@Nullable, especially since that'd also infringe on the implication of the
|
|
event being about villager trades.
