This method gets called when an event you are subscribed to occurs.

Returns
Must return a bitmask of EventListener priorities. When a bit is set, this event won't be delivered to listeners with that priority. It's only allowed/possible to block an event for listeners with a strictly lower priority than this listener. Returning 0 means don't block the event for any listeners.
