JavaException

Nvm fixed it @SubscribeEvent public void playerDeath(LivingExperienceDropEvent event) { if (event.getEntity() instanceof Player) { System.out.println(event.getOriginalExperience()); event.setDroppedExperience(((Player) event.getEntity()).totalExperience); } }

How can I make the player drop all xp that he originally had, or like exactly 50%. I tried to do it with an LivingDeathEvent but i'm not sure how to get the xp level of the player and drop that amount of xp. Im on 19.3
