Problems with Events in BukkitPlugins

Hello,
I recently started writing Plugins for Bukkit-Servers.
I wanted to write a Plugins which does following:
When the Player has a Golden Carrot in his hand, he gets a NightVision-Effect.
To check, if the player holds the item I wanted to use this:

Code:java

public void onPlayerItemHeld(PlayerItemHeldEvent event)
    {
        Player player = event.getPlayer();
        getLogger().info("Test");
        player.sendMessage("Test");
        if(player.getItemInHand().equals(Material.GOLDEN_CARROT))
            {
 
                player.addPotionEffect(new PotionEffect(PotionEffectType.NIGHT_VISION,200,1));
            }
    }

I added getLogger and sendMessage for testing. But nothing happens, there also are no text messages.

What do I do wrong?

It works now, I had to make some changes.

11011100 You added @EvenHandler right? That's all you needed to do.

 

Yes, you have to add @EventHandler above your method that the PlayerItemHeld event is in, you also have to register it, which I usually do when the plugin enables:

Code:

public void onEnable()
{
    Bukkit.getServer().getPluginManager().registerEvents(Listener eventHandler, Plugin plugin);
}
