The XRReferenceSpaceEvent() constructor is used to create a new XRReferenceSpaceEvent object, which represents an event regarding the state of a WebXR reference space object, XRReferenceSpace.

type

A string with the name of the event. It is case-sensitive and browsers always set it to reset.

options

An object that, in addition of the properties defined in Event(), can have the following properties:

referenceSpace

The XRReferenceSpace from which the event originates.

transform

An XRRigidTransform which maps the old coordinate system (from before the changes indicated by this event) to the new coordinate system.

A new XRReferenceSpaceEvent object, initialized as defined by the input parameters.

This simple snippet calls the constructor to create a new reference space event of type reset.

let refSpaceEvent = new XRReferenceSpaceEvent("reset", {
  referenceSpace: myRefSpace,
  transform: myTransform,
});
