What Even Is This, Bukkit Thing?

@최건 is keep making Moto-Online.
(Not dead yet?!)

He asked me to make quesion about this.

Code:

        for (int nvm = 0; ChatColor.stripColor(weapon_attacker.getLore().get(nvm)) == null && ChatColor.stripColor(weapon_attacker.getLore().get(nvm + 1)) == null; nvm++) {
            
            String weapon_attacker_id = ChatColor.stripColor(weapon_attacker.getLore().get(nvm));
            String weapon_victim_id = ChatColor.stripColor(weapon_victim.getLore().get(nvm));
            
            if (weapon_attacker_id.contains("Neutral Damage")) {
                 String raw = weapon_attacker_id.replaceAll("[✤|Neutral|Damage|+| ]", "");
                 String[] split = raw.split("-");
                 Neutral_Damage = range.nextInt(Integer.parseInt(split[2]))+Integer.parseInt(split[1]);
                 attacker.sendMessage(ChatColor.GREEN + Integer.toString(Neutral_Damage));
            }
}

He said it doesn't show anything


Any ideas?
I don't study things on that..

 

It would be easier to help you if you'd post all of the code here
