How to make someone invincible or cancel death message

Hey for one of my plugins I need to be able to either make the player briefly invincible or cancel their death message can someone help please? Thanks in advance

 

PHP:

    @EventHandler
    public void onEntityDamage(EntityDamageEvent event) {
            if (event.getEntity() instanceof Player) {
                event.setCancelled(true);
            }
    }


 

I would try an event. ftbastler posted how to cancel a death event. Here's an example you could use in your listener class. I'm not sure, but I believe this could be used to cancel the default death message and replace it with your own.

PHP:

@EventHandler
    public void fdfd(PlayerDeathEvent event){
        event.setDeathMessage("It's a shame that " + event.getPlayer() + " died.");
    }

 

Ok thanks very much guys I will try these
