IronMan

I'm making a iron man plugin and I'm having some trouble with potion effects. Its only giving me the chestplate potion effect and also its not removing any of the effects.

Code:

@EventHandler
    public void onPlayerMoveEvent(PlayerMoveEvent e){
       
        String uuid = e.getPlayer().getUniqueId().toString();
        Player p = e.getPlayer();
        PlayerInventory pi = (PlayerInventory) p.getInventory();
       
       
        //If the have helmet
        if (helmet.contains(uuid)){
           
            if (pi.getHelmet().getType() == Material.LEATHER_HELMET){
                p.addPotionEffect(new PotionEffect(PotionEffectType.NIGHT_VISION, 100 * 20, 0));
            }else{
                // If they take the helmet off
               
                p.removePotionEffect(PotionEffectType.NIGHT_VISION);
               
            }
           
        }
       
        //If the have chest
        if (chest.add(uuid)){
           
            if (pi.getChestplate().getType() == Material.LEATHER_CHESTPLATE){
                p.addPotionEffect(new PotionEffect(PotionEffectType.DAMAGE_RESISTANCE, 100 * 20, 0));
                p.addPotionEffect(new PotionEffect(PotionEffectType.INCREASE_DAMAGE, 100 * 20, 0));
            }else{
                // If they take the helmet off
               
                p.removePotionEffect(PotionEffectType.DAMAGE_RESISTANCE);
                p.removePotionEffect(PotionEffectType.INCREASE_DAMAGE);
               
            }
           
        }
       
        //If they have leggs
        if (legs.contains(uuid)){
            if (pi.getLeggings().getType() == Material.LEATHER_LEGGINGS){
                p.addPotionEffect(new PotionEffect(PotionEffectType.SPEED, 100 * 20, 1));
            }else{
                // If they take the helmet off
               
                p.removePotionEffect(PotionEffectType.SPEED);
               
            }
        }
       
       
        //If they have boots
        if (boots.contains(uuid)){
            if (pi.getBoots().getType() == Material.LEATHER_BOOTS){
                p.addPotionEffect(new PotionEffect(PotionEffectType.JUMP, 100 * 20, 2));
            }else{
                // If they take the helmet off
               
                p.removePotionEffect(PotionEffectType.JUMP);
               
            }
        }
       
       
       
    }

 

Hi there,
If the Armor is empty, it trows 'NullPointerExceptions'. IT WOULD BE HELPFULL IF YOU'D PUT THAT IN THE TOPIC!

I changed the code a bit, so now it works. Just remodel it like this:

Code:java

if (pi.getHelmet() != null) {
            if (pi.getHelmet().getType() == Material.LEATHER_HELMET){
                p.addPotionEffect(new PotionEffect(PotionEffectType.NIGHT_VISION, 100 * 20, 0));
            }
        } else {
          // If they take the helmet off
          p.removePotionEffect(PotionEffectType.NIGHT_VISION);
        }
