Solved mcMMO skill level

Hey Bukkit,

I looked up the mcMMO and found in the ExpierenceAPI a way to get the level but I wont work. Can someone help me out?

Code:

int lvl = ExperienceAPI.getPlayerRankSkill(p.getUniqueId(), "mining");
p.sendMessage("Mining Level: " + lvl);

This is the error I get:

Code:

And yea I do have depend, plugin in the server etc

 

NullPointerException is usually pretty straightforward. Most likely p is null. Actually p can't be null because you're getting its UUID before passing it to the method, hmm. Take a look at ExperienceAPI.java (decompile it or see if it's open source) and see what's null on line 806.

 

Whatever you're passing on line 26 of dev.java (which is a bad name btw, class names should always be capitalized) is most likely null. Debug those objects and figure out why.

 

it is called dev.java cause the command is /dev either java conf is so far I know is first word lowercase and second word upper. Anyways ill take a look again ty

Ill check line 806 now but it is not my code

Code:

    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
        if(cmd.getName().equalsIgnoreCase("dev")) {
            if(sender instanceof Player) {
                Player p = (Player) sender;
                if(!p.hasPermission("dev.cmd") && p.isOp()) {
                  
                } else {
                    sender.sendMessage(ChatColor.RED + "I told you, you need some special access");
                    if(args.length == 0) {
                      
                    } else {
                        if(args[0].equalsIgnoreCase("s1")) {
                            int lvl = ExperienceAPI.getPlayerRankSkill(p.getUniqueId(), "mining");
                            p.sendMessage("Mining Level: " + lvl);
                        }
                    }
                }
            }
            return true;
        }
        return false;
    }

Problem Fixed! I'm using a other method now!

Just to clarify on this: camelCase only applies to methods and fields. Class names should always be fully capitalized.
