XRVisibilityMaskChangeEvent: session property

Value

An XRSession object indicating which WebXR session the event belongs to.

Examples

This example indicates how you might check a custom userRequestsSessionEnd value when the visibilitymaskchange event fires to see whether the user has manually selected an option to end the XR session. If so, you can access the XRSession via the session property and end the session using XRSession.end().

If the user has not selected this option, you could run some kind of function to render the new view based on the other values available in the XRVisibilityMaskChangeEvent object.

xrSession.addEventListener("visibilitymaskchange", (e) => {
  if (userRequestsSessionEnd) {
    e.session.end();
  } else {
    renderNewView(e.index, e.eye, e.indices, e.vertices);
  }
});
