Context Variables

Each event type automatically injects relevant variables into the script context. Access them via context("variable_name").

event Object (1.13.0.0+)

Starting from version 1.13.0.0, all triggers now have an event object in their context that allows direct access to the Bukkit event object.

The event object is a reflective property resolver that can access event properties through method calls.

Usage Example

on_craft_diamond_sword:
  type: 'crafting'
  recipes:
    - 'minecraft:diamond_sword'
  conditions:
    mode: script
    body:
      - 'if event.get("view").get("player").invoke("getName") == "Yufiria_"'
      - '  tell("The plugin developer is crafting!")'
      - 'endif'
  actions:
    - 'tell("&aCrafting successful!")'
    - 'give_level(100)'

Access Methods

• event.get("propertyName") - Get event property
• .invoke("methodName") - Call method on object
• Chained calls supported: event.get("view").get("player").invoke("getName")

Example: Check Killed Entity Type

on_kill_zombie:
  type: 'kill_entity'
  conditions:
    - 'entity_type == "ZOMBIE"'
  actions:
    - 'tell("&aYou killed a zombie!")'

Example: Check Advancement

on_diamond_advancement:
  type: 'player_advancement'
  conditions:
    - 'advancement == "minecraft:story/mine_diamond"'
  actions:
    - 'tell("&bYou found diamonds!")'
    - 'give_money(1000)'

Example: Check Chat Message

on_keyword:
  type: 'async_player_chat'
  conditions:
    - 'perm("craftorithm.vip")'
  actions:
    - 'tell("&aVIP spoke!")'
