as defined in the inline script above -->
<a-marker preset='hiro' id='marker-hiro' registerevents>
<a-box position='0 0.5 0' material='opacity: 0.5; side: double;color:blue;'>
<a-torus-knot radius='0.26' radius-tubular='0.05'
animation="property: rotation; to:360 0 0; dur: 5000; easing: linear; loop: true">
</a-torus-knot>
</a-box>
</a-marker>
but, since there are no registered listeners for these events, you will not see any effect.
You can register event listeners in your own custom component, defined similarly to
the 'registerevents' in the inline script above -->
<a-marker type='barcode' value='5' id='marker-barcode-5'>
<a-box position='0 0.5 0' material='opacity: 0.5; side: double;color:red;'>
<a-torus-knot radius='0.26' radius-tubular='0.05'
animation="property: rotation; to:360 0 0; dur: 5000; easing: linear; loop: true">
</a-torus-knot>
</a-box>
</a-marker>
<a-entity camera></a-entity>
</a-scene>
