solved

Used this resource: https://bukkit.org/threads/tutorial-create-a-inventory-menu.173571/

So I have this:

Code (Java):

@EventHandler
    public void openShops(InventoryClickEvent event) {
        final Player p = (Player) event.getWhoClicked();
        final ItemStack i = event.getCurrentItem();
        if(i.getItemMeta() != null)
            if(i.getItemMeta().getDisplayName().equals(ChatColor.AQUA + "Weapon Shop")) {
            p.sendMessage("y");
            p.openInventory(WeaponShop.weaponshop);
        } else {
            p.sendMessage("n");
        }
    }

I do get sent the "y" message, so im clicking the right thing, but when i click it, it just exits out and doesn't do anything.

WeaponShop:

Code (Java):

import org.bukkit.Bukkit;
import org.bukkit.ChatColor;
import org.bukkit.Material;
import org.bukkit.enchantments.Enchantment;
import org.bukkit.inventory.Inventory;
import org.bukkit.inventory.ItemStack;

public class WeaponShop {

    public static Inventory weaponshop = Bukkit.createInventory(null, 9, "Weapon Shop");
 
    public static ItemStack stonesword = new ItemStack(Material.STONE_SWORD, 1);
    public static ItemStack ironsword = new ItemStack(Material.IRON_SWORD, 1);
    public static ItemStack escrima = new ItemStack(Material.BLAZE_ROD, 1);

    static {
        stonesword.getItemMeta().setDisplayName(ChatColor.AQUA + "Stone Sword");
        ironsword.getItemMeta().setDisplayName(ChatColor.AQUA + "Iron Sword");
        escrima.getItemMeta().setDisplayName(ChatColor.YELLOW + "Escrima Stick");
        escrima.addUnsafeEnchantment(Enchantment.KNOCKBACK, 3);
        escrima.addUnsafeEnchantment(Enchantment.DAMAGE_ALL, 4);
     
        weaponshop.setItem(0, stonesword);
        weaponshop.setItem(1, ironsword);
        weaponshop.setItem(2, escrima);
    }
 
}
 

 

It is failing at

Code (Text):

p.openInventory(WeaponShop.weaponshop);

No errors

 

I just said no lmao

No

 

Nevermind it works
