[1.10.2] Anyone got a good tutorial on sub blocks?

[SanaRinomi]

I'm looking for an easy to understand tutorial on sub blocks for 1.10.2. Thanks in advanced.

By sub blocks do you mean metadata?

 

*Edit Allow me to rephrase do you mean wool blocks?

Yes, I mean metadata

To use metadata in 1.8+ you need to use blockstates. While blockstates are not limited by amount, metadata is, metadata can only be 0-15(4bits). If you look at wool or even the furnace in vanilla you will see some similarities.

These three methods from BlockColored need to be overrided.

 

    /**
     * Convert the given metadata into a BlockState for this Block
     */
    public IBlockState getStateFromMeta(int meta)
    {
        return this.getDefaultState().withProperty(COLOR, EnumDyeColor.byMetadata(meta));
    }

    /**
     * Convert the BlockState into the correct metadata value
     */
    public int getMetaFromState(IBlockState state)
    {
        return ((EnumDyeColor)state.getValue(COLOR)).getMetadata();
    }

    protected BlockStateContainer createBlockState()
    {
        return new BlockStateContainer(this, new IProperty[] {COLOR});
    }

 

 

As you see all of those loop into the field COLOR which is a Property. Blockstates use properties to define what is looks like from the blockstate JSON. You should use vanilla metadata blocks as a reference.
