Action System

The action system is used across items, entities, and blocks to code custom effects. Actions can run on specific events using the observe component (ex. a player clicking a custom item), or repeat passively using the passive component.

Observe events

Any Geary prefab can observe events using the observe component. It takes a map of event names found in Events to an Action Group.

Examples

observe:
  itemLeftClick:
    - become: parent
    - sendActionBar: "Right clicked item!"

Passive actions

Passive actions run continuously on a Geary prefab, optionally matching against certain components. The passive component takes a list of entries as described below

Parameters

Name	Type	Description
match	List	A list of component names an instance of this prefab must have for the passive system to run
every	Duration	How often to run this action group
run	ActionGroup	The actions to run when an instance is matched

Examples

passive:
  - match: [ inInventory ]
    every: 1s
    run:
      - become: parent
      - ensure:
