Then here is my code in PlayerDeathEvent

Code:java

@EventHandler
    public void onDeath(PlayerDeathEvent e) {
        e.getDrops().clear();
        Player p = e.getEntity();
        if(plugin.kitused.contains(p.getName())) {
            plugin.kitused.remove(p.getName());
            plugin.kangaroo.remove(p.getName());
            plugin.berserker.remove(p.getName());
            plugin.cookiemonster.remove(p.getName());
 
        }
        Player killer = p.getKiller();
        if(plugin.berserker.contains(killer.getName())){
            if(p instanceof Player){
        killer.addPotionEffect(new PotionEffect(PotionEffectType.CONFUSION, 20 * 10, 2));
        killer.addPotionEffect(new PotionEffect(PotionEffectType.INCREASE_DAMAGE, 20 * 7, 1));
            }
        }
            e.getDrops().clear();
    }

Help?

 

trikxgaming killer is null when the player dies of natural causes

 

so should i say if (killer == null) { return; } ?

 

trikxgaming Or just add that in another if statement, no return; needed. Except check to see if the player isn't null instead.

 

Code:java

if(plugin.berserker.contains(killer.getName())){
 
                if(!(killer == null)) {
        killer.addPotionEffect(new PotionEffect(PotionEffectType.CONFUSION, 20 * 10, 2));
        killer.addPotionEffect(new PotionEffect(PotionEffectType.INCREASE_DAMAGE, 20 * 7, 1));
            }
        }

Doesnt work.

 

trikxgaming Add it in below the code where you initialize killer, not where you put it. Have that if statement surround the code you just posted. Checking to see if killer is null is only effective before you use anything from the player.

 

I got it I have to use entitydeathevent

 

trikxgaming That'll work too.

 

Instead of doing that, just do

Code:java

if(killer != null){
 
}
