object - X4 schema type

Meaning#

object: An expression whose interface expects an X4 object reference. Valid syntax does not establish that an object exists.

An XSD type constrains XML, rather than declaring a Lua return or the payload type of event.param. A valid schema value does not prove a successful game effect.

Schema structure#

libraries/common.xsd

restriction narrows a base type; union accepts one of its branches; list describes whitespace-separated items. Enumeration values in one restriction are alternatives. Pattern syntax is XML Schema regex, not Lua patterns or JavaScript RegExp. Constraints inherited from the base type still apply.

Example and result#

<event_object_collided object="$Ship" otherobject="$Other" />

What happens: $Other must refer to an appropriate existing object. The condition filters collisions with it; it does not create a collision.

Object and group variables must already exist in the correct MD / AI context. These are learning fragments, not a complete runnable mission.
