Adding blocks

BlockModel

CustomBlockModel.java

public class CustomBlockModel<T extends Block> extends BlockModelStandard<T> {
    public CustomBlockModel(Block block) {
        super(block);
    }

    public boolean render(Tessellator tessellator, int x, int y, int z) {
        boolean flag = false;

        block.setBlockBounds(0, 0, 0, 1, 1, 1);
        flag = this.renderStandardBlock(tessellator, this.block, x, y, z);

        this.block.setBlockBoundsBasedOnState(BlockModelStandard.renderBlocks.blockAccess, x, y, z);
        return flag;
    }

    public void renderBlockOnInventory(Tessellator tessellator, int metadata, float brightness, float alpha) {

        block.setBlockBounds(0, 0, 0, 1, 1, 1);

        super.renderBlockOnInventory(tessellator, metadata, brightness, 0);
    }
}

It is a regular cube 3D model for our blocks.

The block

CustomBlock.java

public class CustomBlock extends BlockTileEntityRotatable {

    public CustomBlock(String key, int id) {
        super(key, id, Material.metal);
    }
}

Textures from /resources

The block needs textures, which should be created in the directory /resources/your_mod_id_here/textures/block.

Be careful with the name; it's similar to an ID.

Adding it

BlockInitializer.java

public class BlockInitializer {

    public static Block custom_block;
    public void Initialize() {

        BlockBuilder standard_block_builder = new BlockBuilder(MOD_ID); // BlockBuilder is available from Halplibe since 7.1

        // Creating blocks
        BlockBuilder custom_block_builder = standard_block_builder
            .setBlockModel(CustomBlockModel::new)
            .setBlockSound(BlockSounds.METAL)
            .setHardness(1.0F)
            .setResistance(1.0F)
            // Examplemod is your mod id
            .setTextures("examplemod:block/custom_block")
            .setTags(BlockTags.MINEABLE_BY_PICKAXE);
        ;

        custom_block = new CustomBlock("custom_block", 12000));
        custom_block_builder.build(custom_block );
    }
}

ExampleMod.java

public class ExampleMod implements ModInitializer, GameStartEntrypoint, RecipeEntrypoint {

    public static final String MOD_ID = "examplemod";
    public static final Logger LOGGER = LoggerFactory.getLogger(MOD_ID);

    @Override
    public void onInitialize() {
        LOGGER.info("Fishing Additions initialized. Debug: "+ isDebug);
    }

    @Override
    public void beforeGameStart() {

        new BlockInitializer().Initialize();

    }

    @Override
    public void afterGameStart() {
    }

    @Override
    public void onRecipesReady() {

    }

    @Override
    public void initNamespaces() {
    }
}
