I guess this is kind of basic. How does one properly register blocks with multiple states, say, StoneBricks with DEFAULT, CHISELED, MOSSY, and CRACKED variants, so that its variants show up in creative tabs / jei?

(And register item models for all variants, as normal)

override Block#getSubBlocks to return all possible options. 

Thanks for the reply. The Block#getSubBlocks is void, so I assume the following is what's expected:

@Override
    public void getSubBlocks(CreativeTabs itemIn, NonNullList<ItemStack> items) {

        Item itemBricks = new ItemBlockBricks(this);

        items.add(new ItemStack(itemBricks, 1, 0));
        items.add(new ItemStack(itemBricks, 1, 2));
        items.add(new ItemStack(itemBricks, 1, 3));

    }

 

And of course, here's my ItemBlockBricks class

public class ItemBlockBricks extends ItemMultiTexture {

    private static String[] names = new String[]{"bricks_basalt", "", "bricks_basalt_carved", "bricks_basalt_cracked"};

    public ItemBlockBricks(Block block) {

        super(block, block, names);
      	setRegistryName("bricks_basalt");

    }

    @Nonnull
    @Override
    public String getUnlocalizedName(ItemStack stack) {

        int meta = stack.getMetadata();
        return meta < 4 ? names[meta] : "";

    }


}

 

I then register their models using

        ModelLoader.setCustomModelResourceLocation(item, meta, new ModelResourceLocation(item.getRegistryName(), id));

 

where id is passed "inventory", item is passed the custom ItemBlockBricks instance. However, this gives a NullPointerException whose stack trace does not contain my own classes. I've done quite a lot of code-reading trying to get an idea how this is done in other mods, read the Forge documentation, and watched youtube tutorials with no luck. I feel like I'm missing something here.

I am now creating my ItemBlockBricks instance in my Block constructor, with Block#getSubBlocks overridden like this:

@Override
    public void getSubBlocks(CreativeTabs itemIn, NonNullList<ItemStack> items) {
        items.add(new ItemStack(this, 1, 0));
        items.add(new ItemStack(this, 1, 2));
        items.add(new ItemStack(this, 1, 3));
    }

 

I also registered these items using

ModelLoader.setCustomModelResourceLocation(item, meta, new ModelResourceLocation(item.getRegistryName(), id));

 

with meta passed 0, 2, and 3 respectively. This kind of works, now I've got 3 separate slots in JEI/creative tab with the blocks, except that they all have the same texture (with different unlocalized names). Here's my blockstate file:

{ 
        "variants": { 
                "variant=default": { "model": "verbum:bricks_basalt" }, 
                "variant=cracked": { "model": "verbum:bricks_basalt_cracked" }, 
                "variant=carved": { "model": "verbum:bricks_basalt_carved" } 
        } 
}

 

Thank you, it worked.
