I've tried looking around Vanilla code for how to do this, but all the func_x everywhere started to get annoying. How does one add metadata to a block?

 

Edit:

 

So I found a way to have more than 16 versions (infinite really) of the block in one file, as I just make it a new type of block.

Write this in your class, that's the simple way

 

public void setMeta(World world, int x, int y, int z, int meta)
    {
        world.setBlockMetadataWithNotify(x, y, z, MathHelper.clamp_int(meta, 0, 3), 2);
        world.func_147453_f(x, y, z, this);
    }

public void setMeta(World world, int x, int y, int z, int meta)
    {
        world.setBlockMetadataWithNotify(x, y, z, MathHelper.clamp_int(meta, 0, 3), 2);
        world.func_147453_f(x, y, z, this);
    }

Okay, thank you, but how do I change the texture of the block depending on the meta data, as well as use metadeta in a recipe? (I assume registering the block is the same as normal too)

To load textures:

@SideOnly(Side.CLIENT)
@Override
public void registerIcons(IconRegister iconRegister) {
	iconBuffer = new Icon[MetaCount];
                iconBuffer[0] = iconRegister.registerIcon("MODID:" + TextureName1);
                iconBuffer[1] = iconRegister.registerIcon("MODID:" + TextureName2);

        blockIcon = iconBuffer[0];
}

To get textures based on meta:

@SideOnly(Side.CLIENT)
    public Icon getBlockTexture(IBlockAccess par1IBlockAccess, int par2, int par3, int par4, int par5)
    {
          return iconBuffer[par1IBlockAccess.getBlockMetadata(par2, par3, par4)];
    }

To load textures:

@SideOnly(Side.CLIENT)
@Override
public void registerIcons(IconRegister iconRegister) {
	iconBuffer = new Icon[MetaCount];
                iconBuffer[0] = iconRegister.registerIcon("MODID:" + TextureName1);
                iconBuffer[1] = iconRegister.registerIcon("MODID:" + TextureName2);

        blockIcon = iconBuffer[0];
}

To get textures based on meta:

@SideOnly(Side.CLIENT)
    public Icon getBlockTexture(IBlockAccess par1IBlockAccess, int par2, int par3, int par4, int par5)
    {
          return iconBuffer[par1IBlockAccess.getBlockMetadata(par2, par3, par4)];
    }

Is this for 1.7 (I'm asking about 1.7)? Cause I get errors galore (of unimportable things, such as IconRegister -- Did you mean IIConRegister?).
