Solved Targetting a Player

Hello, I was trying to make commands to give people effects. This is part of my onCommand:

Code:java

if(cmd.getName().equalsIgnoreCase("effects")){
        if (Sender.hasPermission("ecore.effects")){
            if(args.length == 0){
            Sender.sendMessage("Done!");
        player.addPotionEffect(new PotionEffect(PotionEffectType.SPEED, 1000000, 90));
        player.addPotionEffect(new PotionEffect(PotionEffectType.JUMP, 1000000, 90));
        player.addPotionEffect(new PotionEffect(PotionEffectType.WATER_BREATHING, 1000000, 90));
        player.addPotionEffect(new PotionEffect(PotionEffectType.ABSORPTION, 1000000, 10));
        player.addPotionEffect(new PotionEffect(PotionEffectType.DAMAGE_RESISTANCE, 1000000, 90));
        player.addPotionEffect(new PotionEffect(PotionEffectType.FAST_DIGGING, 1000000, 90));
        player.addPotionEffect(new PotionEffect(PotionEffectType.FIRE_RESISTANCE, 1000000, 90));
        player.addPotionEffect(new PotionEffect(PotionEffectType.HEAL, 1000000, 90));
        player.addPotionEffect(new PotionEffect(PotionEffectType.HEALTH_BOOST, 1000000, 10));
        player.addPotionEffect(new PotionEffect(PotionEffectType.INCREASE_DAMAGE, 1000000, 90));
        player.addPotionEffect(new PotionEffect(PotionEffectType.INVISIBILITY, 1000000, 90));
        player.addPotionEffect(new PotionEffect(PotionEffectType.NIGHT_VISION, 1000000, 90));
        player.addPotionEffect(new PotionEffect(PotionEffectType.REGENERATION, 1000000, 90));
 
        }if(args.length == 1){
            Player target = Bukkit.getPlayer(args[0]);
            if(target == null){
                Sender.sendMessage(getConfig().getString("prefix").replace("&", "§") + ChatColor.RED + "Player not found.");
            }else{
                target.addPotionEffect(new PotionEffect(PotionEffectType.SPEED, 1000000, 90));
                target.addPotionEffect(new PotionEffect(PotionEffectType.JUMP, 1000000, 90));
                target.addPotionEffect(new PotionEffect(PotionEffectType.WATER_BREATHING, 1000000, 90));
                target.addPotionEffect(new PotionEffect(PotionEffectType.ABSORPTION, 1000000, 10));
                target.addPotionEffect(new PotionEffect(PotionEffectType.DAMAGE_RESISTANCE, 1000000, 90));
                target.addPotionEffect(new PotionEffect(PotionEffectType.FAST_DIGGING, 1000000, 90));
                target.addPotionEffect(new PotionEffect(PotionEffectType.FIRE_RESISTANCE, 1000000, 90));
                target.addPotionEffect(new PotionEffect(PotionEffectType.HEAL, 1000000, 90));
                target.addPotionEffect(new PotionEffect(PotionEffectType.HEALTH_BOOST, 1000000, 10));
                target.addPotionEffect(new PotionEffect(PotionEffectType.INCREASE_DAMAGE, 1000000, 90));
                target.addPotionEffect(new PotionEffect(PotionEffectType.INVISIBILITY, 1000000, 90));
                target.addPotionEffect(new PotionEffect(PotionEffectType.NIGHT_VISION, 1000000, 90));
                target.addPotionEffect(new PotionEffect(PotionEffectType.REGENERATION, 1000000, 90));
                Sender.sendMessage(getConfig().getString("Prefix").replace("&", "§") + "done!");
            }
        }
        }else{
            player.sendMessage(getConfig().getString("Prefix").replace("&", "§") + getConfig().getString("noperm").replace("&", "§"));
        }
    }
        else if(cmd.getName().equalsIgnoreCase("noeffects")){
        if (Sender.hasPermission("ecore.noeffects")){
            if(args.length == 0){
            Sender.sendMessage("Done!");
        for (PotionEffect effect : player.getActivePotionEffects())
              player.removePotionEffect(effect.getType());
            }if(args.length == 1){
                Player target = Bukkit.getPlayer(args[0]);
                if(target == null){
                    Sender.sendMessage(getConfig().getString("prefix").replace("&", "§") + ChatColor.RED + "Player not found.");
                }else{
                    for (PotionEffect effect : target.getActivePotionEffects())
                          target.removePotionEffect(effect.getType());
                    Sender.sendMessage(getConfig().getString("Prefix").replace("&", "§") + ChatColor.BLUE + "effects taken from " + args[0]);
                }
            }
        }
        else{
            player.sendMessage(getConfig().getString("Prefix").replace("&", "§") + getConfig().getString("noperm").replace("&", "§"));
    }
 
}

Everything is working fine when I target an online player, but if the target is an offline player, I get an error :

Code:

Caused by: java.lang.NullPointerException
        at me.Kait18.effects.effects.onCommand(EnstopiaCore.java:263)
        at org.bukkit.command.PluginCommand.execute(PluginCommand.java:44)
        ... 15 more

any idea on how to solve it? Thanks for the help

 

random_username what is on line 263 in the class EnstopiaCore also have return false;

 

line 263 is:

Code:java

                Sender.sendMessage(getConfig().getString("prefix").replace("&", "§") + ChatColor.RED + "Player not found.");

Line 22 on my post return false is at the end, this part is at the middle of my OnCommand

 

random_username
Any IDE errors?

 

What are you replacing here?
replace("&", "§") + ChatColor.RED + "Player not found.");

 

random_username Does the string prefix exist in the config?

 

In string prefix I am using color codes with &, I'm replacing & for §.

Yes, it does

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

random_username post the config.yml here please

 

Code:

#This is the Default Configuration.
 
#Prefix for all messages:
Prefix: '&b[Enstopia] '
 
#Message if player does not have permission:
noperm: '&3You do not have permission to do this.'

 

random_username Probably because you're getting the string "prefix" in your code but in the config it's called "Prefix". Try making it all lower case in the config.

 

This worked, thanks!
