    That is all you need.

    Also a couple of notes:
    Naming conventions!

    Dont cast without checking!

    Use Command#getName(), not label for alias support.


    Dont use the color character directly! use ChatColor instead for future compatibility.

    Is all this code required? You could set the prefix based on the presmission and send the message at the end of the if's, this way you wrap it up a bit and you dont have to change them all one by one in case you want to change it.

    Uhm that stack-trace thing didn't really help I already knew where to find the line of it but I don't know what is wrong with it.
    Edit: If you look at e.g line 36 I don't see how there is an error same with line 27
    I think I'm using the spigot that is 1.8 and 1.7 compatible
    Edit: Now getting this error when running it
    Code:

    @GoogleMaps You really can't tell what is null on this line?
    Code:
             ItemMeta meta = c.getItemMeta();
    I'll give you a hint, doing this
    Code:
    public ItemStack trash,mad,og,drop,ezr,can,des,
    ezs,rekt,babe,getd,wannabe
   = new ItemStack(Material.NAME_TAG);
    Does not set all ItemStacks to a NameTag, it only sets wannabe (The only one that actually has an equals sign)

    He just explained it. Please learn the basics of Java before making Bukkit plugins, it clears this Bukkit forums from 'Java help' instead of actual 'Bukkit help', thanks.

    Right now, all your variables for ItemStacks are null, except 'wannabe'. Set all of them to new ItemStacks, not just wannabe.

    Tagging yourself eh?
    Main 38:
    Now, the error says there is something null on this line:
    • Tagmenu can be null
    • .setLore cannot be null.
    • Chatcolor cannot be null.
    • That string cannot be null
    • tagmenu.trash can be null
    Now here's the fun part. You get to test what is null! Once you find out what's null, then all you need to do is figure out why it's null.

    @GoogleMaps
    If(Something == null)
    //The object is null!

    So would I do like if (tagmenu == null) then I disable the plugin or something and If it's disabled then it is tagmenu but if I do it for the itemstack then we know that it's the itemstack?

    Just test it. The main point of that is to figure out what is null.

    @Zombie_Striker Ok I figured it out but for some reason in the main jar file I have it so it sets the lore if they have a certain permission but it's not setting the lore
