Multible Questions - Help with Doctor who style regeneration.

All of these questions have to do with the same plugin.
Well here is question #1:
Is there a way to cancel death event? more like set their health to maximum right before they die.
Well here is question #2:
I am going to use tagApi to make the player change appearance and name (on command determining the player) But how do I make there name appear different when they chat?

As for special effects and stuff I don't really need much help,
Thanks for reading this

 

1: You can't cancel PlayerDeathEvent, but you could use EntityDamageByEntityEvent and check if they will die with the damage taken, or send a respawn packet.

2: player.setDisplayName().

 

I might be of some assistance.

Code:java

    @EventHandler
    public void onEntityDamage(EntityDamageEvent event)
    {
        if (event.getEntity() instanceof Player)
        {
            Player player = (Player) event.getEntity();
            if (player.getHealth() <= event.getDamage())
            {
                event.setCancelled(true);
                player.setHealth(player.getMaxHealth());
                // Other special effects like explosions and junk if you'd like
            }
        }
    }

 

Thank you!
