Add a sentinel for Item constructor which will prevent item from been registered into Item.itemsList, but still create an instance of an Item. It will be very helpful in creating metadata based items. Like: [spoiler=Item constructor]public Item(int par1) { this.itemID = 256 + par1; if (this.itemID < 0 || this.itemID >= itemsList.length) return; if (itemsList[256 + par1] != null) { System.out.println("CONFLICT @ " + par1 + " item slot already occupied by " + itemsList[256 + par1] + " while adding " + this); } itemsList[256 + par1] = this; GameData.newItemAdded(this); } [spoiler=MetaItem example]public class MetaItem extends Item { // int metadata ->Item item public Set<Integer,Item> metaItems = new HashSet<Integer,Item>(); public MetaItem(int itemID) { super(itemID); setNoRepair(); setMaxDamage(0); setHasSubTypes(true); } public void put(int metadata, Item item) { item.setNoRepair(); item.setMaxDamage(0); item.setHasSubTypes(true); metaItems.put(metadata, item); } // do hooks to desired functions, like this: @Override @SideOnly(Side.CLIENT) public void registerIcons(IconRegister iconRegister) { for (Item i : metaItems.values()) { i.icon = iconRegister.registerIcon(i.iconName); } } @Override public Icon getIconFromDamage(int metadata) { Item i = metaItems.get(metadata); return (i != null) ? i.icon : null; } // ... } [spoiler=MetaItem usage example] public static final int METAID = -257 MetaItem mi = new MetaItem(metaItemID); mi.metaItems.put(0, new ItemGeneric(METAID, ...)); mi.metaItems.put(20, new ItemFood(METAID, ...)); // own subclass from ItemFood mi.metaItems.put(40, new ItemArmor(METAID, ...)); // own subclass from ItemArmor, possibly will work only for non damageable armor, e.g. damage handling need to be moved to nbt by mod developer mi.metaItems.put(60, new ItemTool(METAID, ...)); // own subclass from ItemTool, possibly will work only for non damageable tools, e.g. damage handling need to be moved to nbt by mod developer mi.metaItems.put(100, new ItemDust(METAID, ...)); mi.metaItems.put(200, new ItemIngot(METAID , ...)); mi.metaItems.put(300, new ItemPlate(METAID, ...));

You may do a workaround with render passes, like this: @Override @SideOnly(Side.CLIENT) public boolean requiresMultipleRenderPasses() { return true; } @Override public int getRenderPasses(int metadata) { return 1; } @Override public Icon getIcon(ItemStack stack, int pass) { return ...; }

LexManos, thanks.

I not use OptiFine.

Hello everyone. Sorry for my English. I have found this bug while coding chunk loading addon for IC2. It happens when removing addon and there is chunk loader blocks left in the world. Steps I used to reproduce bug: 1. Install Forge, IC2, own addon; 2. Start game and create a blank superflat world; 3. Place chunk loader blank in the world; 4. Save and exit game; 5. Removed own addon; 6. Start game and tried to load world; 7. Game stuck on "World Loading" screen; It happens only when I use requestPlayerTicket(), but when replace it with requestTicket() and try the same steps world successfully loading and chunk loader block disappearing.
