SharedCure

SharedCure

English | 简体中文

SharedCure is a Paper plugin that implements server-wide villager discount sharing using a small tag (PDC) and Just-In-Time reputation injection approach. When a villager has been cured by any player, this plugin ensures other players who interact with that villager receive the highest trade discount (MAJOR_POSITIVE) without requiring bulk updates across all players.

Features

- Cure capture: Each villager receives a `discount_status` tag (PDC) indicating `UNKNOWN`, `NOT_CURED`, or `CURED` to minimize server-wide operations. - Cure capture: When a player interacts with a villager in the `CURED` state, the plugin will, if necessary, instantly inject `MAJOR_POSITIVE` reputation for the player's UUID, ensuring that the discount is immediately reflected in the trading interface. This only affects the cured reputation (`MAJOR_POSITIVE`) and does not impact other types of reputation. - Cure capture: On plugin load and chunk load, villagers that lack the plugin tag are deep-checked for existing reputations (gossip) and tagged accordingly to support older worlds. - Cure capture: The plugin listens for `EntityTransformEvent` and marks zombie villager conversions as `CURED` instantly.
