Inventory Event

Im trying to get it when a player clicks on a item in their inventory with another item it does something how would I do this?

 

Onlineids Look at InventoryClickEvent.

 

Specifically
ItemStack getCurrentItem()
Gets the ItemStack currently in the clicked slot.
ItemStack getCursor()
Gets the current ItemStack on the cursor.

Alright so I did that but when I click on the item the code doesn't work

Code:java

package me.online.Scraps;
 
import org.bukkit.ChatColor;
import org.bukkit.Material;
import org.bukkit.entity.Player;
import org.bukkit.event.Listener;
import org.bukkit.event.inventory.InventoryClickEvent;
import org.bukkit.inventory.ItemStack;
import org.bukkit.plugin.java.JavaPlugin;
 
public class Main extends JavaPlugin implements Listener{
 
        public void onEnable() {
            getServer().getPluginManager().registerEvents(this, this);
        }
    public void onClick(InventoryClickEvent event){
        Player player = (Player) event.getWhoClicked();
        ItemStack item = event.getCursor();
        ItemStack item1 = event.getCurrentItem();
        if(item.getType() == Material.LEATHER){
            if(item1.getType() == Material.WOOD_SWORD){
                int max = item1.getType().getMaxDurability();
                int dura = item1.getDurability();
                double perc = dura/max;
                double newdura = perc + .05;
                double fin = newdura * max;
                String i = item1.getType().toString();
                item1.setDurability((short) fin);
                player.getInventory().remove(item);
                String mess = ChatColor.BOLD + "Scrap and " + ChatColor.BOLD + i + ChatColor.BOLD + " Combined!";
                player.sendMessage(ChatColor.AQUA + mess);
            }
        }
    }
}
 

 

You forgot the annotation
@EventHandler

Also, not sure how true this is, but I think setting a double to an integer divided by another integer will result in a whole number, you might need to cast double, not exactly sure

Edit: I was right, here's an output

Code:

        int x = 10;
        int y = 24;
        double z = x/y;
        System.out.println(z);
        z = (double) x / (double) y;
        System.out.println(z);

Console

Code:

0.0
0.4166666666666667

 

Theres a problem now i get both the success message and the unsuccess one and it doesnt take my item im trying to combine:

Code:java

package me.online.Scraps;
 
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.inventory.InventoryClickEvent;
import org.bukkit.inventory.ItemStack;
import org.bukkit.plugin.java.JavaPlugin;
 
public class Main extends JavaPlugin implements Listener{
 
    public void onEnable() {
        getServer().getPluginManager().registerEvents(this, this);
    }
    @SuppressWarnings("deprecation")
    @EventHandler
    public void onClick(InventoryClickEvent event){
        Player player = (Player) event.getWhoClicked();
        ItemStack item = event.getCursor();
        ItemStack item1 = event.getCurrentItem();
        if(item.getType() == Material.LEATHER){
            if(item1.getType() == Material.WOOD_SWORD){
                double o = (double) item1.getDurability()/ (double) item1.getType().getMaxDurability();
                if(o <= .95){
                    int max = item1.getType().getMaxDurability();
                    int dura = item1.getDurability();
                    double perc = (double) dura / (double) max;
                    double newdura = perc - .05;
                    double fin = newdura * max;
                    String i = item1.getType().toString();
                    String l = i.replace("_", " ");
                    String k = l.toLowerCase();
                    item1.setDurability((short) fin);
                    item.setType(Material.AIR);
                    String mess = ChatColor.BOLD + "Scrap and " + ChatColor.BOLD + k + ChatColor.BOLD + " Combined!";
                    player.sendMessage(ChatColor.GREEN + mess);
                    event.setCursor(null);
 
 
                }
 
                String j = item1.getType().toString().toLowerCase().replace("_", " ");                   
                String g = ChatColor.BOLD + "Your " + ChatColor.BOLD + j + ChatColor.BOLD + " is repaired as much as possible!";
                player.sendMessage(ChatColor.RED + g);
            }
        }
}
}
 
 
 
 

 

add "return;" after event.setCursor(null)
