I am attempting to create throwable spawn eggs.

My Item Class:

 

public class ItemThrowableEgg extends Item {
    protected EntityThrowableEgg entityEgg;
    private IIcon theIcon;
    public ItemThrowableEgg() {
        this.setTextureName("spawn_egg");
        this.setUnlocalizedName("thwoableEgg");
        this.setHasSubtypes(true);
        this.setCreativeTab(CreativeTabs.tabMisc);

    }
    @Override
    public ItemStack onItemRightClick(ItemStack par1ItemStack, World par2World, EntityPlayer par3EntityPlayer)
    {
        if (!par3EntityPlayer.capabilities.isCreativeMode)
        {
            --par1ItemStack.stackSize;
        }

        par2World.playSoundAtEntity(par3EntityPlayer, "random.bow", 0.5F, 0.4F / (itemRand.nextFloat() * 0.4F + 0.8F));

        if (!par2World.isRemote)
        {
            entityEgg = new EntityThrowableEgg(par2World, par3EntityPlayer);
            entityEgg.setEntityToSpawn(par1ItemStack.getItemDamage());
            par2World.spawnEntityInWorld(entityEgg);
        }

        return par1ItemStack;
    }

    public String getItemStackDisplayName(ItemStack p_77653_1_)
    {
        String s = ("" + StatCollector.translateToLocal(this.getUnlocalizedName() + ".name")).trim();
        String s1 = EntityList.getStringFromID(p_77653_1_.getItemDamage());

        if (s1 != null)
        {
            s = s + " " + StatCollector.translateToLocal("entity." + s1 + ".name");
        }

        return s;
    }

    @SideOnly(Side.CLIENT)
    public int getColorFromItemStack(ItemStack p_82790_1_, int p_82790_2_)
    {
        EntityList.EntityEggInfo entityegginfo = (EntityList.EntityEggInfo)EntityList.entityEggs.get(Integer.valueOf(p_82790_1_.getItemDamage()));
        return entityegginfo != null ? (p_82790_2_ == 0 ? entityegginfo.primaryColor : entityegginfo.secondaryColor) : 16777215;
    }

    @SideOnly(Side.CLIENT)
    public boolean requiresMultipleRenderPasses()
    {
        return true;
    }

    /**
     * Gets an icon index based on an item's damage value and the given render pass
     */
    @SideOnly(Side.CLIENT)
    public IIcon getIconFromDamageForRenderPass(int p_77618_1_, int p_77618_2_)
    {
        return p_77618_2_ > 0 ? this.theIcon : super.getIconFromDamageForRenderPass(p_77618_1_, p_77618_2_);
    }

    /**
     * returns a list of items with the same ID, but different meta (eg: dye returns 16 items)
     */
    @SideOnly(Side.CLIENT)
    public void getSubItems(Item p_150895_1_, CreativeTabs p_150895_2_, List p_150895_3_)
    {
        Iterator iterator = EntityList.entityEggs.values().iterator();

        while (iterator.hasNext())
        {
            EntityList.EntityEggInfo entityegginfo = (EntityList.EntityEggInfo)iterator.next();
            p_150895_3_.add(new ItemStack(p_150895_1_, 1, entityegginfo.spawnedID));
        }
    }

    @SideOnly(Side.CLIENT)
    public void registerIcons(IIconRegister p_94581_1_)
    {
        super.registerIcons(p_94581_1_);
        this.theIcon = p_94581_1_.registerIcon(this.getIconString() + "_overlay");
    }
}

 

The item is registered like so:

GameRegistry.registerItem(new ItemThrowableEgg(), "thowableSpawnEggSpawn", MODID);

The item works fine until I try to create an EntityItem out of it:

 

ItemThrowableEgg throwableEgg = new ItemThrowableEgg();

ItemStack is = new ItemStack(throwableEgg,1, id);

e.drops.add(new EntityItem(e.entity.worldObj, e.entity.posX, e.entity.posY, e.entity.posZ, is));[/code]

 

When I get a huge stack trace and a NullPointerException as it tries to render in the inventory:

The entityitem I see on the ground before picking it up has a missing texture. When I get a throwableEgg from my creative inventory and drop it, the texture looks fine.

 

Why is this?

You should only be making a new ItemThrowableEgg ONCE, and then referencing that instance everywhere else (assuming you only have one ItemThrowableEgg - if you have more, make multiple instances).

 

That's why in every item-making tutorial, you always see stuff like this:

public static Item throwableEgg;

// preInit
throwableEgg = new ItemThrowableEgg();
GameRegistry.registerItem(throwableEgg, 'throwableEgg', modid);

ItemStack egg = new ItemStack(YourMod.throwableEgg);

throwableEgg is the reference that you can use everywhere, because the item only exists as a single object - if you made a new Item for every single item in the game, that would waste a lot of memory.

A nullpointerexception is when you are trying to access a variable that is null. This means if you don't initialize a variable before using it, you will get this exception.
