[1.12.2] How can I use subblock?

[NyasRoryo]

... I mean multi block use an ID, use damage to distinguish. Who can give a example .java file with basic code to create and registry it and its ItemBlock? If you can show me how to give a TranslationKey, that's fantastic! Please help me... I've been trying for three days, I look ic2, te5 and even gtce, and I still can't understand how to meta-hack the block...

 

my code: 

package com.github.nyasroryo.lanticaltech.common.block.buildmaterial;

import com.github.nyasroryo.lanticaltech.common.block.BlockBase;
import net.minecraft.block.Block;
import net.minecraft.block.properties.PropertyEnum;
import net.minecraft.block.state.BlockStateContainer;
import net.minecraft.block.state.IBlockState;
import net.minecraft.creativetab.CreativeTabs;
import net.minecraft.item.EnumDyeColor;
import net.minecraft.item.Item;
import net.minecraft.item.ItemBlock;
import net.minecraft.item.ItemStack;
import net.minecraft.util.IStringSerializable;
import net.minecraft.util.NonNullList;

public class CeramicTile extends BlockBase {

  private static final String NAME = "CeramicTile";
  public static final Block THIS_BLOCK = new CeramicTile();
  public static final Item THIS_ITEMBLOCK = new ItemBlock(THIS_BLOCK).setRegistryName(NAME);

  public static final PropertyEnum<EnumColor> COLOR = PropertyEnum.create("color", EnumColor.class);

  public CeramicTile() {
    super(NAME); //set Hardness, resistance, sound etc. in other class
    setDefaultState(this.blockState.getBaseState().withProperty(COLOR, EnumColor.WHITE));
  }

  @Override
  protected BlockStateContainer createBlockState() {
    return new BlockStateContainer(this, COLOR);
  }

  @Override
  public IBlockState getStateFromMeta(int metadata) {
    return this.getDefaultState().withProperty(COLOR, EnumColor.values()[metadata]);
  }

  @Override
  public int getMetaFromState(IBlockState state) {
    return state.getValue(COLOR).ordinal();
  }

  @Override
  public int damageDropped(IBlockState state) {
    return getMetaFromState(state);
  }

  @Override
  public void getSubBlocks(CreativeTabs itemIn, NonNullList<ItemStack> items)
  {
    for (EnumDyeColor enumdyecolor : EnumDyeColor.values())
    {
      items.add(new ItemStack(this, 1, enumdyecolor.getMetadata()));
    }
  }



  public static enum EnumColor implements IStringSerializable {
    WHITE("white"),
    BLACK("black"),
    RED("red"),
    BLUE("blue"),
    GREEN("green"),
    YELLOW("yellow"),
    ORANGE("orange"),
    GREY("grey"),
    PURPLE("purple"),
    CYAN("cyan"),
    PINK("pink"),
    MAGENTA("magenta"),
    BROWN("brown"),
    LIGHTBLUE("lightblue"),
    LIGHTGREY("lightgrey"),
    LIGHTGREEN("lightgreen");

    private String name;

    private EnumColor(String color)
    {
      this.name = color;
    }

    @Override
    public String getName()
    {
      return this.name;
    }

    @Override
    public String toString()
    {
      return this.name;
    }
  }
}

Registry and error:

      ForgeRegistries.BLOCKS.register(CeramicTile.THIS_BLOCK);
      ForgeRegistries.ITEMS.register(CeramicTile.THIS_ITEMBLOCK);
      ModelLoader.setCustomModelResourceLocation(CeramicTile.THIS_ITEMBLOCK, 0, new ModelResourceLocation("CeramicTile","inventory"));
      ModelLoader.setCustomModelResourceLocation(CeramicTile.THIS_ITEMBLOCK, 1, new ModelResourceLocation("CeramicTile","inventory"));
      ModelLoader.setCustomModelResourceLocation(CeramicTile.THIS_ITEMBLOCK, 2, new ModelResourceLocation("CeramicTile","inventory"));

I don't know why you commented this out, because you need it.

@Draco18s

Sorry, I just commented it when I was debugging, but it throws NullPointerExpection after removing the comment.

And how can I do now... Plz help me thx

Somehow your property is null when it gets passed to the BlockStateContainer constructor.

 

Also, you don't need BlockBase. There's already a "base" block class, its called Block.

emm...

当它传递给BlockStateContainer构造函数时，你的属性以某种方式为null。

 

此外，您不需要BlockBase。已经有一个“基础”块类，它叫做Block。

How a correct createBlockState like, plz show me thanks!!!

and about BlockBase.class, I put hardness, resistance setter in it(because my mod's block's data is integrated in a class

I look tf's code just now. Almost same, and I fail
