Caused by: java.lang.NullPointerException

Code:java

@EventHandler
public void OnEntityDamageByEntity(EntityDamageByEntityEvent event)
{
if(!(event.getDamager() instanceof Arrow) || !(event.getEntity() instanceof Player))
return;
 
Player player = (Player)event.getEntity();
Arrow arrow = (Arrow)event.getDamager();
if(arrow.getShooter() == null || !(arrow.getShooter() instanceof Player))
return;
 
KitPlayer iPlayer = IKits.getInstance().getPlayer(((Player)arrow.getShooter()).getName());
if(iPlayer.getKit().equals(Kit.BOWMAN))
{
player.setVelocity(arrow.getVelocity().multiply(3));
player.setFireTicks(80);
}
}

 

getDamager is a HumanEntity (Player) so it cannot be checked as an arrow.

Is there an option for getCause()?
