Issue when spawning projectile

I'm trying to make a special plugin that allows certain tools to fire snowballs that have different amount of damage on impact, but when I try to right click my tools (currently only a stone tool) it does not do anything. Here is my current code.

Code:

package com.enjin.zamoscraft.minez;
 
import org.bukkit.Bukkit;
import org.bukkit.plugin.java.JavaPlugin;
 
 
public class MineZ extends JavaPlugin
{
    @Override
    public void onEnable()
    {
        this.getLogger().info("======ZamosCraft MineZ ENABLED======");
        Bukkit.getPluginManager().registerEvents(new MineZListener(this), this);
    }
   
    @Override
    public void onDisable()
    {
        this.getLogger().info("======ZamosCraft MineZ DISABLED======");
    }
}

Code:

package com.enjin.zamoscraft.minez;
 
import org.bukkit.Material;
import org.bukkit.entity.Entity;
import org.bukkit.entity.Player;
import org.bukkit.entity.Snowball;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.entity.EntityDamageByEntityEvent;
import org.bukkit.event.player.PlayerInteractEvent;
import org.bukkit.inventory.ItemStack;
import org.bukkit.metadata.FixedMetadataValue;
 
public class MineZListener implements Listener
{
    private MineZ instance;
 
    public MineZListener(MineZ instance)
    {
        this.instance = instance;
    }
   
    @EventHandler
    public void onPlayerRightClick(PlayerInteractEvent event)
    {
        Player player = event.getPlayer();
       
        if(!(player.getItemInHand() == new ItemStack(Material.STONE_HOE))) return;
       
        Snowball snow = (Snowball) player.launchProjectile(Snowball.class);
        snow.setMetadata("MineZ", new FixedMetadataValue(instance, "STONE"));         
       
    }
   
    @EventHandler
    public void onEntityDamage(EntityDamageByEntityEvent event)
    {   
        if(!(event.getEntity() instanceof Player)) return;
       
        Entity entity = event.getDamager();
        if(entity instanceof Snowball && entity.hasMetadata("MineZ")){
            if(entity.getMetadata("MineZ").toString().equals("STONE")){
                event.setDamage(8);
            }
            if(entity.getMetadata("MineZ").toString().equals("DIAMOND")){
                //WIP
            }
        }   
    }
 
}

I've been looking for a fix for a long time, and I would be grateful if someone could help me find the issue.

 

if(!(player.getItemInHand() == new ItemStack(Material.STONE_HOE))) return;
I think this is your problem here, you should do something more like
Material.STONE_HOE.equals(player.getItemInHand().getType())
or maybe
Material.STONE_HOE.getId() == player.getItemInHand().getTypeId()

 

That actually works, thanks, but I forgot to mention the fact that the snowball is supposed to damage the target a bit more than usual, so that is my other problem.

 

You should print entity.getMetadata("MineZ").toString() out to console to see whats happening

 

Code:

[org.bukkit.metadata.FixedMetadataValue@436d4b50]

This is what I get when I print it to the console, I have no idea what it means.

 

The getMetadata only returns the FixedMetaDataValue, so you have to get the value of this FixedMeadataValue.
entity.getMetadata(...).get(0).asString().equals(...);

 

Thanks everyone, it works perfect now.
