Custom Item Disappears After Exiting World

[qpwoeiruty]

My custom item leaves my inventory after I save and quit the world then enter again, no clue why.

[qpwoeiruty]

There is the item code:

 

package com.blocklings.items;

import net.minecraft.entity.Entity;
import net.minecraft.entity.EntityList;
import net.minecraft.entity.IEntityLivingData;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;
import net.minecraft.nbt.NBTTagCompound;
import net.minecraft.util.MathHelper;
import net.minecraft.util.StatCollector;
import net.minecraft.world.World;

import com.blocklings.entity.EntityBlockling;
import com.blocklings.main.Blocklings;

public class ItemBlockling extends Item {

public EntityBlockling blockling;

public int level, xp, upgrade, special;

public String blocklingName, name;

public ItemBlockling() {

	super();
	this.setUnlocalizedName("blockling");
	this.setMaxStackSize(1);
	this.setTextureName(Blocklings.MODID + ":" + "blockling");

}

public ItemBlockling(String name, int level, int xp, int upgrade, int special) {

	super();
	this.setUnlocalizedName("blockling");
	this.setMaxStackSize(1);
	this.setTextureName(Blocklings.MODID + ":" + "blockling");

	blocklingName = name;
	this.level = level;
	this.xp = xp;
	this.upgrade = upgrade;
	this.special = special;

}

@Override
public void onUpdate(ItemStack itemStack, World world, Entity entity, int i, boolean b) {

	itemStack.stackTagCompound = new NBTTagCompound();

	if(blocklingName.length() > 0) {

		name = blocklingName;

	} else {

		name = "Blockling";

	}

	for(int j = 0; j < 1; j++) {

		itemStack.stackTagCompound.setString("name", blocklingName);
		itemStack.stackTagCompound.setInteger("level", level);
		itemStack.stackTagCompound.setInteger("xp", xp);
		itemStack.stackTagCompound.setInteger("upgrade", upgrade);
		itemStack.stackTagCompound.setInteger("special", special);

	}

	level = itemStack.stackTagCompound.getInteger("level");

}

@Override
public ItemStack onItemRightClick(ItemStack itemStack, World world, EntityPlayer player) {

	EntityBlockling blockling = new EntityBlockling(world, level, xp, upgrade, special);

	blockling.setLocationAndAngles(player.posX, player.posY, player.posZ, MathHelper.wrapAngleTo180_float(world.rand.nextFloat() * 360.0F), 0.0F);
        blockling.onSpawnWithEgg((IEntityLivingData)null);
        if(!world.isRemote) world.spawnEntityInWorld(blockling);
        if(!world.isRemote) world.playSoundAtEntity(blockling, "fireworks.twinkle1", 1.0F, 1.0F); 
        if(!world.isRemote) itemStack.stackSize--;
        
        return itemStack;
        
    }

@Override
public String getItemStackDisplayName(ItemStack itemStack) {

        return name;
        
    }

}

I thought because I am using NBT that the variables would be different as they get saved and then set again, or am I missing something? When I have two different items they work fine, as if they were two different items.

[qpwoeiruty]

They need to be used in multiple methods and I need to remove the first constructor.

[qpwoeiruty]

That makes sense, sorry. However, why does doing this in my entity class, mean the item that I pick up disappears after I exit the world?

 

if(this.isDead && !this.worldObj.isRemote) {

		this.worldObj.spawnEntityInWorld(new EntityItem(this.worldObj, posX, posY, posZ, new ItemStack(new ItemBow().setUnlocalizedName("bow").setTextureName("bow")))); 

	}

new ItemBow()

You are creating a new item instance. The game doesn't know what it is after reload. Thus the info gets discarded.

Use "Items.bow".

If I wanted to do it like that for a custom item that takes parameters in the constructor depending on things within the entity class, how can I do that? I thought that would be the way to do it.
