Hello, I have a custom slab class, these custom slabs function normally. Aside from two things;

 

One:

The slabs do not stack, when I place them on each-other there's a big empty space.

 

Two:

When I click in with the scroll wheel of my mouse, it gives me a stone slab instead. It's the same thing with any custom block that extends a vanilla block, is there a method to fix this?

 

Picture of my problem:

I have also tried to register the "ItemSlab" in postInit from the following tutorial (Changing the syntax to 1.7.10 myself), but it was of no use, my blocks simply wouldn't stack.

 

 

Here's my registry and slab class.

 

Registering:

 

orangeHalfSlab = new OrangeSlab(false, CreativeTabs.tabBlock, "orangehalfslab");
orangeDoubleSlab = new OrangeSlab(true, null, "orangefullslab");

 

 

Slab Class (Cut out import statements):

 

public class OrangeSlab extends BlockSlab {

public OrangeSlab(boolean isFullBlock, CreativeTabs tab, String  blockName) {
	super(isFullBlock, Material.wood);

	if(tab != null){
		setCreativeTab(tab);
	}

	setBlockName(Constants.MODID + "_" + blockName);
	setHardness(1.5F);
	GameRegistry.registerBlock(this, blockName);
}

@Override
public void registerBlockIcons(IIconRegister iconRegister){
	this.blockIcon = iconRegister.registerIcon(Constants.MODID + ":" + "orangeplank");
}

@Override
public String func_150002_b(int p_150002_1_) {
	return getUnlocalizedName();
}



}

 

 

To reiterate, the issue is not with texturing, but the fact the slabs do not change to doubleslabs when placed together, thank you for your time.

For double slabs, you need to register a custom ItemBlock with the block. Have a look at ItemSlab in vanilla.

Okay, so, I implemented a class that extends ItemSlab. The issue is that I'm getting an ID overlap. (Two of the same Id, I think) So it crashes Minecraft upon startup.

 

ItemSlab class:

 

public class OrangeItemSlab extends ItemSlab{

String name = "orangeitemslab";

public OrangeItemSlab(Block block){
	super(block, (BlockSlab)ModBlocks.orangeHalfSlab, (BlockSlab)ModBlocks.orangeDoubleSlab, false);
	setUnlocalizedName(Constants.MODID + "_" + name);
	this.setMaxDamage(0);
    this.setHasSubtypes(true);
    GameRegistry.registerItem(this, name);
}

}

 

 

The use of the class:

 

OrangeItemSlab orangeSlab = new OrangeItemSlab(ModBlocks.orangePlank);

 

 

Error Log (Some of it):

        Et Cetera...

 

 

 

(Edit) For additional reference, here is the source GameData.class method where the error points to:

 

private void freeSlot(int id, Object obj)
    {
        FMLControlledNamespacedRegistry<?> registry = (obj instanceof Block) ? iBlockRegistry : iItemRegistry;
        Object thing = registry.getRaw(id);

        if (thing != null && thing != obj)
        {
            throw new IllegalStateException(String.format("Can't free registry slot %d occupied by %s", id, thing)); //----This is thrown
        }

        availabilityMap.clear(id);
    }

 

When you are registering your block, you need to specify the ItemBlock too.

GameRegistry.registerBlock(block,CustomItemBlock.class,name);

 

Solved, took me awhile because I am slightly retarded.
