Game items state

Hi Alex!

Yup, that'd probably be the way to go. The elements of Drag and Drop (draggables and droppables) communicate with each other and with the main component via events, and the draggables and droppables are exposed. So, if you get hold of the instance of Drag and Drop, you can listen to the events - I fear "dragend" is the best you get. You can try a dry run in the dev console in the iframe's context, e.g. with something like

H5P.instances[0].draggables.forEach(draggable => {
  draggable.on('dragend', () => {
    // Access draggable or H5P.instances[0] here as you please
  });
});

Please note, however, that when that event is triggered and you start looking for the data you need (e.g. H5P.instances[0].getCurrentState() for a test run), not all the processing may have been done, so not all information may have been updated already.

Best,
Oliver
