Adding Enchantments To ItemStacks In Inventories.

I made an ItemStack which contained a sword and added an Enchantment for it look nice. But the encahnted effect doesnt come up in the inventory.

Code:

package me.Azrex.InventoryGUI;

import org.bukkit.Bukkit;
import org.bukkit.ChatColor;
import org.bukkit.Material;
import org.bukkit.enchantments.Enchantment;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.block.Action;
import org.bukkit.event.inventory.InventoryClickEvent;
import org.bukkit.event.player.PlayerInteractEvent;
import org.bukkit.inventory.Inventory;
import org.bukkit.inventory.ItemStack;
import org.bukkit.inventory.meta.ItemMeta;
import org.bukkit.plugin.java.JavaPlugin;

public class Main extends JavaPlugin implements Listener{

    @Override
    public void onDisable() {
    }

    @Override
    public void onEnable() {
       
        getServer().getPluginManager().registerEvents(this, this);
       
    }
       
       
    private void openGUI(Player player) {
        Inventory inv = Bukkit.createInventory(null, 27, ChatColor.RED + ":-Crate Key-:");
           
        //Getting The Items       
        ItemStack sword = new ItemStack(Material.DIAMOND_SWORD);
        ItemMeta swordMeta = sword.getItemMeta();
       
        ItemStack axe = new ItemStack(Material.DIAMOND_AXE);
        ItemMeta axeMeta = axe.getItemMeta();
       
        //Item Names
        swordMeta.setDisplayName(ChatColor.RED + "The Sword Of Truth");
        sword.setItemMeta(swordMeta);
       
        axeMeta.setDisplayName(ChatColor.GREEN + "Thor's Axe");
        axe.setItemMeta(axeMeta);
       
        inv.setItem(12, sword);
        inv.setItem(14, axe);
       
        sword.addEnchantment(Enchantment.DAMAGE_ALL, 2);
       
       
        player.openInventory(inv);
       
        }
   

   
    @EventHandler
    public void OnPlayerInteract(PlayerInteractEvent event) {
        Action a= event.getAction();
        ItemStack is = event.getItem();
       
        if(a == Action.PHYSICAL || is == null || is.getType()==Material.AIR)
            return;
       
             if (is.getType() == Material.COMPASS)
              openGUI(event.getPlayer());
    }
   
        @EventHandler   
        public void OnInventoryClick(InventoryClickEvent event) {
           
            if(!ChatColor.stripColor(event.getInventory().getName()).equalsIgnoreCase(":-Crate Key-:"))
                return;
            Player player = (Player) event.getWhoClicked();
                    event.setCancelled(true);
               
                    if(event.getCurrentItem()== null || event.getCurrentItem().getType()==Material.AIR || !event.getCurrentItem().hasItemMeta()){
                        player.closeInventory();
                        return;
                       
                    }
                   
        }
       
    
}

 

If you create a new itemstack instance, you need to add the enchantment before you set the item in the inventory, but what u cán do is use inv.getItem(<slot>).addEnchantment

 

you should add the enchantment before the ItemStack, not before the add in the inventory

    private void openGUI(Player player) {
        Inventory inv = Bukkit.createInventory(null, 27, ChatColor.RED + ":-Crate Key-:");
        
        //Getting The Items   
        ItemStack sword = new ItemStack(Material.DIAMOND_SWORD);
        ItemMeta swordMeta = sword.getItemMeta();
        sword.addEnchantment(Enchantment.DAMAGE_ALL, 0);
    
        ItemStack axe = new ItemStack(Material.DIAMOND_AXE);
        ItemMeta axeMeta = axe.getItemMeta();
    
        //Item Names
        swordMeta.setDisplayName(ChatColor.RED + "The Sword Of Truth");
        sword.setItemMeta(swordMeta);
    
        axeMeta.setDisplayName(ChatColor.GREEN + "Thor's Axe");
        axe.setItemMeta(axeMeta);
    
        inv.setItem(12, sword);
        inv.setItem(14, axe);
    
    
    
        player.openInventory(inv);
    
        }


    @EventHandler
    public void OnPlayerInteract(PlayerInteractEvent event) {
        Action a= event.getAction();
        ItemStack is = event.getItem();
    
        if(a == Action.PHYSICAL || is == null || is.getType()==Material.AIR)
            return;
    
             if (is.getType() == Material.COMPASS)
              openGUI(event.getPlayer());
    }

        @EventHandler

                        player.closeInventory();
                        return;
                    
                    }
                
        }
    

}
