Hello,

 

I have been struggling to resolve an "Attempted to set registry name with existing registry name! New: striketheblightmod:planks Old: striketheblightmod:planks" error. Basically, I have a BlockPlank class to register two plank variants using an EnumHandler. I would like to ask if anyone can help find out what's wrong as I couldn't find the culprit.

 

more error details:

BlockPlank

public class BlockPlank extends Block implements IHasModel, IMetaName {

	private String name;
	
	public BlockPlank(String name) {
		super(Material.WOOD);
		setUnlocalizedName(name);
		setRegistryName(name);
		setCreativeTab(Main.modTab);
		setSoundType(SoundType.WOOD);
		setDefaultState(this.blockState.getBaseState().withProperty(VARIANT, EnumHandler.EnumType.WILLOW));
		this.name = name;
		
		BlockList.BLOCKS.add(this);
		ItemList.ITEMS.add(new ItemBlockVariants(this.setRegistryName(this.getRegistryName())));                 // line 41

	}
	
	@Override
	public void getSubBlocks(CreativeTabs itemIn, NonNullList<ItemStack> items) {
		for(EnumHandler.EnumType blockplank$enumtype : EnumHandler.EnumType.values()) {

		}
	}
	
	@Override
	public IBlockState getStateFromMeta(int meta) {
		return this.getDefaultState().withProperty(VARIANT, EnumHandler.EnumType.byMetadata(meta));
	}

	@Override
	public int getMetaFromState(IBlockState state) {
		return ((EnumHandler.EnumType)state.getValue(VARIANT)).getMeta();
	}
	
	@Override
	public ItemStack getPickBlock(IBlockState state, RayTraceResult target, World world, BlockPos pos, EntityPlayer player) {
		return new ItemStack(Item.getItemFromBlock(this), 1, getMetaFromState(world.getBlockState(pos)));
	}
	
	@Override
	protected BlockStateContainer createBlockState() {
		return new BlockStateContainer(this, new IProperty[] {VARIANT});
	}
	
	@Override
	public String getSpecialName(ItemStack stack) {
		return EnumHandler.EnumType.values()[stack.getItemDamage()].getName();
	}
	
	@Override
	public void registerModels() {
		for (int i = 0; i < EnumHandler.EnumType.values().length; i++) {
			Main.proxy.registerVariantRenderer(Item.getItemFromBlock(this), i, EnumHandler.EnumType.values()[i].getName() + "_planks", "inventory");
		}
	}
	
}

 

EnumHandler:

public class EnumHandler {

	public static enum EnumType implements IStringSerializable{
		
		WILLOW(0, "willow"), REDWOOD(1, "redwood");
		
		private static final EnumType[] META_LOOKUP = new EnumType[values().length];
		private final int meta;
		private final String name, unlocalizedName;
		
		private EnumType(int meta, String name) {
			this(meta, name, name);
		}
		
		private EnumType(int meta, String name, String unlocalizedName) {
			this.meta = meta;
			this.name = name;
			this.unlocalizedName = unlocalizedName;
		}
		
		@Override
		public String getName() {
			return this.name;
		}
		
		public String getUnlocalizedName() {
			return this.unlocalizedName;
		}
		
		public int getMeta() {
			return this.meta;
		}
		
		@Override
		public String toString() {
			return this.name;
		}
		
		public static EnumType byMetadata(int meta) {
			return META_LOOKUP[meta];
		}
		
		static {
			for (EnumType enumType : values()) {
				META_LOOKUP[enumType.getMeta()] = enumType;
			}
		}
	}
}

 

line 38 in BlockList (other people call the class BlockInit):

	public static final Block PLANKS = new BlockPlank("planks");

 

ItemBlockVariants:

public class ItemBlockVariants extends ItemBlock{
	
	public ItemBlockVariants(Block block) {
		super(block);
		setHasSubtypes(true);
		setMaxDamage(0);
	}
	
	@Override
	public int getMetadata(int damage) {
		return damage;
	}
	
	@Override
	public String getUnlocalizedName(ItemStack stack) {
		return ((IMetaName)this.block).getSpecialName(stack) + "_" + super.getUnlocalizedName();  //e.g.: willow_planks
	}
	
}

 

I usually resolve errors on my own but this one has me pondering for a while ^^ Thanks in advance,

IHasModel

Kill this with fire. You do not need this. All this interface does is make you implement the same code over and over and over again.

 

ALL items need models. All of them. And none of the information necessary to register that model is private. Just loop through your block and item lists in your model registry event. 

 

Anyway, you haven't provided enough code to identify the problem.

public static final Block PLANKS = new BlockPlank("planks");

Also don't use a static initializer to register blocks/items.

I have since stopped using IHasModel. That was not the issue, but I managed to sort it out. Basically:

 

		ItemList.ITEMS.add(new ItemBlockVariants(this.setRegistryName(this.getRegistryName())));                 // line 41

should have been:

		ItemList.ITEMS.add(new ItemBlockVariants(this).setRegistryName(this.getRegistryName()));                 // line 41

Damn syntax mistakes causing trouble ? This thread can now be closed.

 

Thanks for the advice.

Or don't. You don't have to do it. Its not a forum rule, just a thing some people do because they think its helpful.
