Solved When right click item do /buy help.

Greetings me again, I've tried to find a tutorial on how to make a item do /buy when you press it, but I cant find any tutorials or forums post on how to do it. I've tried to do find this out for ages but now I've given up. Please anyone help me. And if people are wondering why I posted to threads within a hour its only because I got tired of trying to find out those problems. But please help me with this one.
Code so far:

Code:java

package me.BeastCraft3.inventorygui;
 
import java.util.ArrayList;
 
import org.bukkit.ChatColor;
import org.bukkit.Material;
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.player.PlayerDropItemEvent;
import org.bukkit.event.player.PlayerInteractEvent;
import org.bukkit.event.player.PlayerJoinEvent;
import org.bukkit.inventory.ItemStack;
import org.bukkit.inventory.meta.ItemMeta;
 
public class donate implements Listener {
 
    public Main plugin;
 
 
    ItemStack diamond = new ItemStack(Material.DIAMOND);{
        ItemMeta diamondmeta = diamond.getItemMeta();
        ArrayList<String> cc = new ArrayList<String>();
        diamondmeta.setDisplayName(ChatColor.YELLOW + "Donation Ranks");
        cc.add(ChatColor.GRAY + "View our donator packages");
        diamondmeta.setLore(cc);
        diamond.setItemMeta(diamondmeta);
      }
 
    @EventHandler
    public void onPd(PlayerDropItemEvent e) {
        Player p = e.getPlayer();
 
        if (e.getItemDrop().getItemStack().getType().equals(Material.DIAMOND)) {
            p.sendMessage(String.format("%sError: %sYou are not Allowed to drop that item!", ChatColor.RED, ChatColor.DARK_RED));
            e.setCancelled(true);
        }
 
 
    }
 
    @EventHandler
    public void OnPlayerJoin(PlayerJoinEvent e){
 
        if(!(e.getPlayer().hasPlayedBefore())){
            e.getPlayer().getInventory().addItem(new ItemStack(diamond));
        }
    }
 
 
    @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;
    }
 
}
 

 

Not sure you means this.. Meh.. Hope this help!

Code:java

private void playerRunCommand(Player p, String cmd)
{
    p.chat(cmd);
}

 

This is what Im trying to explain: When you right click the diamond it will execute the command /buy from buycraft
Hope my english isnt that bad

 

And you should do this:

Code:java

@EventHandler
public void onPlayerInteract(PlayerInteractEvent event) {
Action a = event.getAction();
ItemStack is = event.getItem();
 
if (a == Action.RIGHT_CLICK_AIR && is != null && is.getType() != Material.AIR)
p.chat("/buy")
}

EDIT: Oh it should be /buy Meh..

 

BeastCraft3 He told you the answer.

PHP:

p.chat("/help");

EDIT: Wow, ninja'd again. ;L

 

BeastCraft3 Would look something like this:

Code:java

@EventHandler
public void onPlayerInteract(PlayerInteractEvent event) {
Action a = event.getAction();
ItemStack is = event.getItem();
if (a != Action.PHYSICAL && is != null) {
if (is.getType() == Material.ARROW) { // Whatever material/criteria you have for the item
Bukkit.dispatchCommand(event.getPlayer(), "buy");
}
}
}

Edit: the ninja is real

 

It is really really simple to do!
Try this thing:

Code:java

 @EventHandler
public void interact1(PlayerInteractEvent e){
if (!(e.getAction() == Action.RIGHT_CLICK_AIR)) return;
if (!(e.getItem().getType() == Material.DIAMOND)) return;
     Player p = e.getPlayer;
     p.performCommand("buy");
}
