Solved Right Click Specific Block with Specific Item

Hi guys, what is the code where if I click (for example) a diamond block with a diamond, it would give you an emerald or something like that.

My code so far:

Code:

package me.epiccraft21.core;

import org.bukkit.Location;
import org.bukkit.Material;
import org.bukkit.block.Block;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.player.PlayerInteractEvent;
import org.bukkit.inventory.ItemStack;
import org.bukkit.plugin.java.JavaPlugin;

public class Main extends JavaPlugin{
 
@EventHandler
public void onBlockClicked(Block block, Location loc, PlayerInteractEvent e){
    Player p = e.getPlayer();
    if(block.getType() == Material.DIAMOND_BLOCK){
        if(p.getItemInHand().getType() == Material.DIAMOND){
            p.getInventory().addItem(new ItemStack(Material.EMERALD, 1));
            p.getInventory().removeItem(new ItemStack(Material.DIAMOND));
        }
    }

 

Here's a tip! Using Pastebin or the 'Insert Code' tool above helps format your code for easier reading!

Edit: Thanks for updating your thread!

 

@EpicCraft21

Yeah. I'm not even trying to read the code when it's like that. Make things easier to read so people will be more likely to help you.

 

Ok, sorry. I didn't know about that.

 

public class Main extends JavaPlugin implements Listener

Adding the "implements Listener" part allows you to listen to events in this class.

You also need to register the listener so bukkit knows it exists. Add this method:

Code:

public void onEnable(){
  this.getServer().getPluginManager().registerEvents(this, this);
}

 

Make sure your class implements Listener and that the event is registered.

If you're having problems with your EventHandler try using this:

Code:

  @EventHandler
  public void onClickBlock(PlayerInteractEvent e) {
      Player p = e.getPlayer();
      if (p.getItemInHand().getType().equals(Material.DIAMOND)) {
      if (e.getAction().equals(Action.RIGHT_CLICK_BLOCK)) {
          Block b = e.getClickedBlock();
          if (b.getType().equals(Material.DIAMOND_BLOCK)) {
              if (p.getItemInHand().getAmount() > 1) {
                  p.getItemInHand().setAmount(p.getItemInHand().getAmount() -1);
                  p.getInventory().addItem(new ItemStack(Material.EMERALD));
              } else {
                  p.getInventory().remove(p.getItemInHand());
                  p.getInventory().addItem(new ItemStack(Material.EMERALD));
              }
          }
      }
  }
  }

 

@EpicCraft21 If you are wondering where people are getting this information:

• http://wiki.bukkit.org/Event_API_Reference

Also, event methods only have one object parameter passed to them and that is the event!

 

Thanks, this worked perfectly!
