How to execute commands in an event

Hello!

I am creating a plugin thats in development stage that lets a player right click with an item, when they right ckick it pops up witha 9 slot inventory. I want to see how i get it soo, I can left click on an item in the inventory and it will execute an essentials command, like a /sudo but when they click the item in the inventory I already have the inventory define i just need help on the cklick of the item in inv and running essentials commands. If I could have some code that would be great. Cheers.

Main(Only class):

Code:

package com.gmail.cooperclark132.plugin.test;

public class Main extends JavaPlugin implements Listener {
    public static Inventory testInventory;
    public static Inventory welcomeInventory;
    public void onEnable() {
        testInventory = Bukkit.createInventory(null, 9, ChatColor.DARK_AQUA + "Potion");
        PluginManager pm = this.getServer().getPluginManager();
        pm.registerEvents(this, this);
        welcomeInventory = Bukkit.createInventory(null, 9, ChatColor.RED + "Welcome");
 
    }
    public void onDisable() {
       
    }
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
        if(cmd.getName().equalsIgnoreCase("hello")) {
            sender.sendMessage("Hello there " + ChatColor.GREEN+sender.getName()+".");
            return true;
        }
        return false;
    }   
    @EventHandler
    public void OnPlayerInteract(PlayerInteractEvent e) {
        Player p = e.getPlayer();
        int blockId = p.getItemInHand().getType().getId();
        ItemStack diamond = (new ItemStack(Material.DIAMOND, 1));
        if(blockId == 369) {
            p.openInventory(testInventory);
            String name = "" + ChatColor.GREEN+ChatColor.BOLD+"GoldenMC";
            testInventory.addItem(setName(diamond, name, null));
            p.sendMessage("It works!");
            }
        String name3 = "Info";
        if(blockId == 264) {
                p.openInventory(welcomeInventory);
                ItemStack blaze = new ItemStack((Material.BLAZE_ROD));
                welcomeInventory.addItem(setName(blaze, name3, null));
            }   
   
        }
   
 
   
    @EventHandler
    public void onPlayerJoin(PlayerJoinEvent e) {
        Player p = e.getPlayer();
        String name2 = "" + "Info";
        ItemStack diamond = (new ItemStack(Material.DIAMOND, 1));
        p.getInventory().addItem(setName(diamond, name2, null));
        p.addPotionEffect(new PotionEffect(PotionEffectType.SPEED, 500, 1));
        e.setJoinMessage(ChatColor.GREEN + p.getName() +" Joined the game!");
       
 
 
    }
      static ItemStack setName(ItemStack is, String name, String size)
      {
        ItemMeta im = is.getItemMeta();
        if (name != null)
        {
          im.setDisplayName(name);
        }
 
        im.setLore(Arrays.asList(new String[] { "GoldenMC" }));
        is.setItemMeta(im);
        return is;
      }
 
 
}

the code is a bit dodgey atm, its like my playing plugin thing

 

coobro123 Listen to InventoryClickEvent and check what item is clicked (event.getCurrentItem()) then you can use:

Code:

player.performCommand("The command you want to be performed");

Just tell me if you need more help.

 

Well, left-clicking on your inventory picks up the item, so I would suggest using a PlayerPickupItemEvent:

Code:

@EventHandler
public void OnPlayerPickupItem(PlayerPickupItemEvent event)
{
//stuff here
}

 

You could use event.setCancelled(true) to stop picking the item...

 

xmarinusx i need some help with that. I wan't a command inside my eventhandler.

 

Be a bit more specefic please, if you just want a command to be executed from the player use:

Code:java

 
player.performCommand("gamemode 0") //This would set the player's gamemode on survival
 

Note that you can better use player.setGamemode(GameMode.SURVIVAL) for this, I just gave an example.

 

Can i do this in an if statement xmarinusx?

 

Asgernohns Of course you can...
What do you need it for, actually?

 

xmarinusx tp cmd in an eventhandler. Sry i'm not answering, I am enjoying my summer holodays, with no internet at the hotel rooms. I need to go to the lobby every time I need internet.

 

Asgernohns
Why would you need to execute a command for that from inside your code? You'd better just use something like "player.teleport();"

 

xmarinusx i need to teleport to a pressed sign location.
