Solved Removing some enchantments

Hi guys, I'm trying to remove some enchantments for a PvP Server, I tried many ways but I have not found the right way yet :/ I hope someone will help me

Code:

Code:java

private List<Enchantment> allowed = Arrays.asList(PROTECTION_ENVIRONMENTAL, FIRE_ASPECT, LOOT_BONUS_MOBS, DIG_SPEED, DAMAGE_ALL, PROTECTION_FALL,
                                                      ARROW_DAMAGE, ARROW_INFINITE, ARROW_FIRE, DURABILITY, LOOT_BONUS_BLOCKS, SILK_TOUCH);
 
    @EventHandler
    public void onEnchantItem(EnchantItemEvent e) {
        Map<Enchantment, Integer> enchants = e.getEnchantsToAdd();
        Iterator<Enchantment> iterator = enchants.keySet().iterator();
        while(iterator.hasNext()) {
            Enchantment en = iterator.next();
            if(!(allowed.contains(en))) enchants.remove(en);
        }
    }

You can't modify a list while you're iterating over it, hence the CocurrentModificationException, simply replace enchants.remove(en) with iterator.remove()

Use iterator.remove() instead. Also I don't think removing the enchantment from the map will do anything.

 

Thanks, It's working Yes, it do something, it's written in the doc
