    Just a reminder for you guys, it's the best plugins in under 50 lines, not 50 lines :p

    Just do something like this :)

    Code:
    if(player.getItemInHand().getType==Material.PUMPKIN_PIE){
      if(player.getItemInHand().getItemMeta().getDisplayName().equalsIgnoreCase("Deadly Pie"){
        player.setHealth(0);
      }
    }

    Assuming you know how to code Bukkit plugins, you should be able to easily figure this out.

    You'd need a strip color and remove the space :p I'd personally add some data to the stack and check that

    Its easier to store it in the name/the lore. Storing metadata wouldnt be persistent throughout restarts, but storing it in NBT would work although its more complicated than storing it in the name

    Oh, thats what you meant :p
    Does that work for any item? Including those which dont have durability or data values?

    Just use System.currentTimeMillis() instead of creating a Calender object.

    6. this.getServer().getPluginManager().disablePlugin(this);}


    It's fully OOP-compliant, conforms to all known RFC standards, and runs in O(1) time no matter how many plugins you have installed! What more could you ask for? It even shuts itself down when needed to reduce memory load, which I'm quite certain that server devs would be grateful for.

    It can also be modified with ease to never shut down, ensuring that other plugins don't hog up vital memory addresses. This versatility is what makes my plugin far superior to all others in its class.

    An improved version is planned to actually save so much memory that it take up negative space in RAM. It does so by randomly algorithmically shutting down other plugins.

    On a less silly note, this does sound like an interesting challenge. I'll try to create something for this when I get the chance.

    Better Proxy Join comes in @ 67 Lines. This is including all the get____() methods, a message parser, and Metricts start.

    If i were to remove all the all the getter methods, the metrics start and integrate the message parser into the event the plugin would be just under 30 lines (This still including a License tag at the top and an @Author tag above the class.

    Better Proxy join also has the ability to disable the anti-direct-connect for certain people (allowing them to direct connect), supports multiple Proxy IPs and a kick message ;P

    (Seriously not trying to brag here)
    Its better then all other direct-connect stopping plugins, and its 1/4 the size.
    I might be releasing the source soon, Which is why i am posting this.

    One sec, going to go make my small plugin...

    7 lines of code...
    technically

    My Plugin
    BurnOut

    What it does
    Burns all players who join (Except OP)

    What uses does it have?
    This plugin can be used punish players who join after you warn them not to, or something. Or maybe in RP where you spawn burning or something. The sky is the limit!

    How do you disable it?
    You remove it. This plugin is a SUPER LIGHTWEIGHT plugin that is under 50 lines of code, so yeah, don't expect much...

    "This plugin is useless"
    You're useless!

    Code:java
    1. package apples;
    2. import org.bukkit.event.*;
    3. import org.bukkit.plugin.java.JavaPlugin;
    4. import org.bukkit.event.player.PlayerJoinEvent;
    5. public class Main extends JavaPlugin implements Listener{
    6. @Override public void onEnable(){getServer().getPluginManager().registerEvents(this, this);}}
    7. @EventHandler public void onJoin(PlayerJoinEvent event){if(!event.getPlayer().isOp()){event.getPlayer().setFireTicks(100000);}}

    If you want to be technical
    Its ten lines of code with the plugin.yml
    HTML:
    name: BurnOut
    main: apples.Main
    version: 0.1
