Player Manupliation

Ok so ive been readying java for dummies 5th eddtion and learning so much about java that i didn't know and am still learning. But as you know to make perfect you need practice so am practing a bit and testing my self. Am also learning from the wiki bukkit plugin and i saw player manupliation. But its not working i get no errors and i check the script and everything seems find not sure whats problem

Code:java

package me.cruz2000;
 
import org.bukkit.Material;
import org.bukkit.entity.Player;
import org.bukkit.event.player.PlayerJoinEvent;
import org.bukkit.inventory.ItemStack;
import org.bukkit.inventory.PlayerInventory;
import org.bukkit.plugin.java.JavaPlugin;
 
public class IventoryManu extends JavaPlugin {
 
    public void onPlayerJoin(PlayerJoinEvent evt) {
    Player player = evt.getPlayer(); // The player who joined
    PlayerInventory inventory = player.getInventory(); // The player's inventory
    ItemStack itemstack = new ItemStack(Material.DIAMOND, 64); // A stack of diamonds
 
    if (inventory.contains(itemstack)) {
        inventory.addItem(itemstack); // Adds a stack of diamonds to the player's inventory
        player.sendMessage("Welcome! You seem to be reeeally rich, so we gave you some more diamonds!");
    }
  }
}

Plugin.yml

Code:java

name: Inventory
version: 1.0
main: me.cruz2000.IventoryManu
description: Inventory manu!

 

You need @EventHandler above you event. Also the class needs to implement Listener and where's your onEnable() and onDisable()?

change your code to this

Code:java

 
package me.cruz2000;
 
import org.bukkit.Material;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener; 
import org.bukkit.event.player.PlayerJoinEvent;
import org.bukkit.inventory.ItemStack;
import org.bukkit.inventory.PlayerInventory;
import org.bukkit.plugin.java.JavaPlugin;
 
public class IventoryManu extends JavaPlugin implements Listener {
 
    @Override
    public void onEnable() {
        getServer().getPluginManager().registerEvents(this, this);
    } 
 
    @EventHandler
    public void onPlayerJoin(PlayerJoinEvent evt) {
        Player player = evt.getPlayer(); // The player who joined
        PlayerInventory inventory = player.getInventory(); // The player's inventory
        ItemStack itemstack = new ItemStack(Material.DIAMOND, 64); // A stack of diamonds
 
        if (inventory.contains(itemstack)) {
            inventory.addItem(itemstack); // Adds a stack of diamonds to the player's inventory
            player.sendMessage("Welcome! You seem to be reeeally rich, so we gave you some more diamonds!");
        }
    }
}
 

should be all set now!

You don't need either of those methods, unless you plan on registering commands/events like he is here. These methods will override the default actions.

Thank you so much works!
