Silently catching entity tracking error что это

That’s where I actually add the entity to the NMS world. And it seems to think that every time I create a new one that it’s actually the same one. The error only gets thrown when I try to fire one before the previous one has died.
The code I showed you wasn’t my actual code it was just the basic part of what I was doing. I didn’t really want to show you that because in order to show you everything I have to show you 4 different classes.
Anyways here you go:

Highest up class:

package com.xern.jogy34.tardis.weapons;
import net.minecraft.server.v1_6_R1.World;
import org.bukkit.ChatColor;
import org.bukkit.Material;
import org.bukkit.inventory.ItemStack;
import org.bukkit.inventory.meta.ItemMeta;
public class MagneticBeacon extends TimeWeapon
    private static ItemStack me;
    public MagneticBeacon(World world)
        super(world, Material.FLINT.getId(), 0);
    public TimeWeaponType getType()
        return TimeWeaponType.MAGNETIC_BEACON;
    public ItemStack getWeaponStack()
        me = new ItemStack(Material.FLINT);
        ItemMeta im = me.getItemMeta();
        im.setDisplayName(ChatColor.DARK_RED + "BASIC MAGNETIC BEACON");
        WeaponHelper.addWeapon(MagneticBeacon.class, me, 50);

All of the overriden methods are for my plugin and don’t have to do with EntityItem
TimeWeapon:

package com.xern.jogy34.tardis.weapons;
import org.bukkit.Location;
import org.bukkit.util.Vector;
import net.minecraft.server.v1_6_R1.EntityItem;
import net.minecraft.server.v1_6_R1.ItemStack;
import net.minecraft.server.v1_6_R1.World;
public abstract class TimeWeapon extends EntityItem implements ITimeWeapon
    public TimeWeapon(World world, int id, int data)
        this.uniqueID = UUID.randomUUID();
        this.setItemStack(new ItemStack(id, 1, data));
    public void shoot(double d0, double d1, double d2, float f, float f1)
        WeaponHelper.shoot(d0, d1, d2, f, f1, this);
    public void setVelocity(Vector v)
    public void setPosition(Location loc)
        super.setPosition(loc.getX(), loc.getY(), loc.getZ());

ITimeWeapon (interface):

package com.xern.jogy34.tardis.weapons;
import org.bukkit.Location;
import org.bukkit.inventory.ItemStack;
import org.bukkit.util.Vector;
import net.minecraft.server.v1_6_R1.IProjectile;
public interface ITimeWeapon extends IProjectile
    public TimeWeaponType getType();
    public ItemStack getWeaponStack();
    public void setVelocity(Vector v);
    public void setPosition(Location loc);

            if(w.getBlockAt(x, y, z).getTypeId() != 0 || (e.motX == 0 && e.motY == 0 && e.motZ == 0))
                TARDIS t = TARDIS.getTardisByLocation(new Location(w, x, y, z), false, false);
                    TimeWeaponHitTARDISEvent event = new TimeWeaponHitTARDISEvent(t, ((ITimeWeapon)e));
                    Bukkit.getPluginManager().callEvent(event);
    public static void shoot(double d0, double d1, double d2, float f, float f1, Entity e)
        float f2 = MathHelper.sqrt(d0 * d0 + d1 * d1 + d2 * d2);

        e.lastPitch = e.pitch = (float) (Math.atan2(d1, (double) f3) * 180.0D / 3.1415927410125732D);
    public static class WeaponStackAndPrice
        public final ItemStack weaponStack;
        public WeaponStackAndPrice(ItemStack weaponStack, int price)
            this.weaponStack = weaponStack;
    private static HashMap<WeaponStackAndPrice, Class<? extends ITimeWeapon>> allWeapons = 
            new HashMap<WeaponStackAndPrice, Class<? extends ITimeWeapon>>();
    public static void addWeapon(Class<? extends ITimeWeapon> weapon, ItemStack weaponStack, int price)
        allWeapons.put(new WeaponStackAndPrice(weaponStack, price), weapon);
    public static WeaponStackAndPrice[] getAllWeaponStacksAndPrices()
        return allWeapons.keySet().toArray(new WeaponStackAndPrice[0]);
    public static ItemStack getStackFromWeapon(Class<? extends ITimeWeapon> weapon)
        for(WeaponStackAndPrice wap : allWeapons.keySet())
            if(allWeapons.get(wap).equals(weapon))
    public static Class<? extends ITimeWeapon> isWeaponStack(ItemStack is)
        for(WeaponStackAndPrice w : allWeapons.keySet())
            ItemStack cur = w.weaponStack;
            if(is.getType().equals(cur.getType()))
                if(is.getItemMeta().equals(cur.getItemMeta()))
                    if(is.getEnchantments().equals(cur.getEnchantments()))
                        return allWeapons.get(w);

I use this so that I don’t have to keep rewriting the same code as not all of my weapon classes come from TimeWeapon as currently one of them is a firework and not an item

Anyone?

Does NMS automatically add the item to the tracker. It could be not that all the items are the same but that the item has been added already by another section.

Try printing put all the tracked items and see if they are the same or if it’s what I’m thinking.

Entities are added to the tracker when you add them into the NMS world. And I already know that the tracker contains an EntityItem that it thinks is the same one as a new one that I try to fire which is one that was previously fired. If it didn’t think it was already tracked then it wouldn’t be throwing the error and it would actually be fireing and if it didn’t think that the one that is already tracked is the one that was previously fired then it would be throwing the error at times when one wasn’t out there that was previously fired or it would sometimes allow it to fire when one is already out there.

Anyone?
