StringBuilder (Make all args one string) (open) StringBuilder (Make all args one string) (close)

StringBuilder str = new StringBuilder(args[0]);
for(int i = 1; i < args.length; i++) {
str.append(' ').append(args);
}

Update Notifier (Notify whenever there's an update) (open) Update Notifier (Notify whenever there's an update) (close)

Replace the comments accordingly, and also in the URL it should be a .txt file and the only thing that should be in it is the version, such as 1.0.4 or 1.3.
try {
URL url = new URL("THE-URL");
BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream()));
String string;
while ((string = in.readLine()) != null) {
int current = Integer.parseInt(Bukkit.getServer().getPluginManager().getPlugin("YOUR-PLUGIN").getDescription().getVersion().replace(".", ""));
int new = Integer.parseInt(string.replace(".", ""));
if (current < new) {
// NEW VERSION!
} else {
// THERE ISNT A NEW VERSION!
}
}
in.close();
} catch (MalformedURLException e) {
// URL IS INVALID!
} catch (IOException e) {
// BAD READ/WRITE!
}

Nice! Do you mind if you or I put it in a BukkitDev paste?

 

Oh, I don't mind if you do ^^

 

Update notifier ^^
Do whatever you want with it, such as on player login send them a message, or anything else

 

For those out there who use custom files:

Code:JAVA

    public void initializeFile() throws IOException{
        File f = new File(yourjavapluginclass.getDataFolder().getAbsoluteFile(), "/somefilename.somefilextension");
        File folder = new File(yourjavapluginclass.getDataFolder().getAbsoluteFile().getAbsolutePath());
        if(!folder.exists()){
            folder.mkdir();
        }
        if(!f.exists()){
            f.createNewFile();
        }
    }

 

Funny how I have a thread just like this and you have the exact same ArgumentCollector (you called it StringBuilder), looks suspicous!

Oops. Well I got it from my plugin and not your thread I can even show you the source code I got it from, it's on Github.

 

Ok, I believe you haha

 

Want to only trigger move events when players move to a new block and not just twitch/look around?

Code:

public void onPlayerMove(PlayerMoveEvent event) {
        if(event.isCancelled()==false &&
                (event.getTo().getBlockX() != event.getFrom().getBlockX() ||
                event.getTo().getBlockY() != event.getFrom().getBlockY() ||
                event.getTo().getBlockZ() != event.getFrom().getBlockZ())){
       
        //CODE GOES HERE
        }
}

 

Method which will change skin of Skull:

Code:java

 
    public ItemStack setSkin(ItemStack item, String nick){
        CraftItemStack craftStack = null;
        net.minecraft.server.ItemStack itemStack = null;
        if (item instanceof CraftItemStack) {
            craftStack = (CraftItemStack) item;
            itemStack = craftStack.getHandle();
        }
        else if (item instanceof ItemStack) {
            craftStack = new CraftItemStack(item);
            itemStack = craftStack.getHandle();
        }
        NBTTagCompound tag = itemStack.tag;
        if (tag == null) {
            tag = new NBTTagCompound();
        }
        tag.setString("SkullOwner", nick);
        itemStack.tag.setCompound("display", tag);
        itemStack.tag = tag;
        return craftStack;
    }
