Script callback

saturn:js

Calls a callback registered by KubeJS and passes the params argument.

A trigger matches published server signals. It can be used in trigger rules or triggered abilities; registration itself does not perform any action. See the trigger lifecycle.

JSON fields

Field	Type	Required	Default	Description
type	Resource ID	yes	—	saturn:js
signal	Resource ID	yes	—	ID of the signal the script trigger subscribes to.
id	String	yes	—	Identifier of the callback, option or entry.
params	Object	no	{}	Parameter object passed to the script or formula.

Registered only when KubeJS is installed. The JSON only selects an existing callback; it never executes JavaScript strings from the JSON directly.

JSON example

{
  "type": "saturn:js",
  "signal": "saturn:tick",
  "id": "example_callback",
  "params": {}
}

This is a value to embed in the corresponding field, not a standalone loadable data pack file. The example: references in the examples must be replaced with defined entries.
