Item Causing Crash When Rendering

novemcinctus · November 16, 2014

In my mod, I have created a new item for throwable spawn eggs:

ItemThrowableEgg.java

Reveal hidden contents

public class ItemThrowableEgg extends Item {
    public int colorBase;
    public int colorSpots;
    protected EntityThrowableEgg entityEgg;
    protected int entityId;
    private IIcon theIcon;

    public ItemThrowableEgg(int entityId, int parPrimaryColor, int parSecondaryColor) {
        this.setTextureName("spawn_egg");
        this.entityId = entityId;
        this.maxStackSize = 64;
        this.setCreativeTab(CreativeTabs.tabMisc);
        colorBase = parPrimaryColor;
        colorSpots = parSecondaryColor;
    }
    public ItemThrowableEgg(int entityId) {
        this.setTextureName("spawn_egg");
        this.entityId = entityId;
        this.maxStackSize = 64;
        this.setCreativeTab(CreativeTabs.tabMisc);
        colorBase = ((EntityList.EntityEggInfo)EntityList.entityEggs.get(Integer.valueOf(entityId))).primaryColor;
        colorSpots = ((EntityList.EntityEggInfo)EntityList.entityEggs.get(Integer.valueOf(entityId))).secondaryColor;
    }
    @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(entityId);
            par2World.spawnEntityInWorld(entityEgg);
        }

        return par1ItemStack;
    }

    @Override
    @SideOnly(Side.CLIENT)
    public int getColorFromItemStack(ItemStack par1ItemStack, int parColorType)
    {
        return (parColorType == 0) ? colorBase : colorSpots;
    }

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

    @Override
    public String getItemStackDisplayName(ItemStack par1ItemStack) {
        return "Throwable Spawn "+ EntityList.getStringFromID(this.entityId);
    }


    @Override
    @SideOnly(Side.CLIENT)
    public void registerIcons(IIconRegister par1IconRegister) {
        super.registerIcons(par1IconRegister);
        this.theIcon = par1IconRegister.registerIcon(this.getIconString() + "_overlay");
    }

    @Override
    @SideOnly(Side.CLIENT)
    public IIcon getIconFromDamageForRenderPass(int par1, int par2) {
        return par2 > 0 ? this.theIcon : super.getIconFromDamageForRenderPass(par1, par2);
    }

}

And I register it and all of its forms in preInit like so:

snippet from main class preInit:

Reveal hidden contents

Iterator it = EntityList.entityEggs.entrySet().iterator();
        while (it.hasNext()) {
            Map.Entry pair = (Map.Entry) it.next();
            int currentMobId = ((Integer)pair.getKey()).intValue();
            int foregroundColor = ((EntityList.EntityEggInfo)pair.getValue()).secondaryColor;
            int backgroundColor = ((EntityList.EntityEggInfo)pair.getValue()).primaryColor;
            ItemThrowableEgg currentItem = new ItemThrowableEgg(currentMobId, backgroundColor, foregroundColor);
            GameRegistry.registerItem(currentItem, "thowableSpawnEggSpawn"+EntityList.getStringFromID(currentMobId), MODID);
        }

All of that works fine. It appears with the correct texture in the correct inventory slot and behaves exactly as expected on right click.

However, I ran into problems trying to create an EntityItem out of it. I have another class that is an event handler for LivingDropsEvent. In this class, spawn eggs are added to the drops of various mobs. The function I use to create an itemstack is this:

Reveal hidden contents

private ItemStack thowableEggFor(int mobId) {
        ItemThrowableEgg throwableEgg = new ItemThrowableEgg(mobId);
        return new ItemStack(throwableEgg);
}

it is then appended to the drops with:

e.drops.add(new EntityItem(e.entity.worldObj, e.entity.posX, e.entity.posY, e.entity.posZ, throwableEggFor([appropriate id]);

This is where everything gets messed up. When I kill a mob, I see it drops an item with the black and purple checkered texture used for items without one. When I pick it up, the game crashes:

[12:56:36] [server thread/INFO]: Stopping server[/spoiler][code]
I tried creating an EntityItem somewhere else in the code and had the same issue. It is worth noting that if the bottom 9 slots of my inventory are full and I cannot see items I pick up, the game will only crash when I open my inventory.

Do not create that many Items! You should use damage value or ItemStack NBT data.

Sorry, I'm somewhat new to Forge. What's the best way to set and retrieve the damage value? Should I put it in the constructor?

I see that the setDamage function takes an ItemStack as a parameter. Are damage values associated with individual items?
