Different Light Levels Based on Metadata

[HenryRichard]

I'm trying to make a block that changes light level based on it's metadata. I've got it to kind-sorta work, but not very well - it only works if I use /setblock. This is the code:

package com.henrich.epicwasteoftime.blocks;

import com.henrich.epicwasteoftime.EWOTCreativeTabs;

import net.minecraft.block.Block;
import net.minecraft.block.material.Material;
import net.minecraft.block.properties.IProperty;
import net.minecraft.block.properties.PropertyBool;
import net.minecraft.block.state.BlockState;
import net.minecraft.block.state.IBlockState;
import net.minecraft.creativetab.CreativeTabs;
import net.minecraft.util.BlockPos;
import net.minecraft.world.IBlockAccess;
import net.minecraft.world.World;

public class PinkiteBlock extends Block {

public static final PropertyBool POWERED = PropertyBool.create("powered");

protected static final int onLight = (int)(15.0F * 1f);
protected static final int offLight = (int)(15.0F * 0f);

public PinkiteBlock(String unlocalizedName, Material material) {
	super(material);
	this.setUnlocalizedName(unlocalizedName);
	this.setDefaultState(this.blockState.getBaseState().withProperty(POWERED, false));
                this.setCreativeTab(EWOTCreativeTabs.ewotBlocks);
}

public PinkiteBlock(String unlocalizedName) {
	this(unlocalizedName, Material.rock);
}
    
    @Override
protected BlockState createBlockState() {
    return new BlockState(this, new IProperty[] { POWERED });
}
    
    @Override
public IBlockState getStateFromMeta(int meta) {
	switch(meta) {
	case 0:
		return getDefaultState().withProperty(POWERED, false);
	case 1:
		return getDefaultState().withProperty(POWERED, true);
	default:
		return getDefaultState().withProperty(POWERED, false);
	}
}
    
    @Override
public int getMetaFromState(IBlockState state) {
    return state == this.getDefaultState() ? 0 : 1;
}
    
    @Override
    /**
     * Get a light value for the block at the specified coordinates, normal ranges are between 0 and 15
     *
     * @param world The current world
     * @param pos Block position in world
     * @return The light value
     */
    public int getLightValue(IBlockAccess world, BlockPos pos)
    {
        Block block = world.getBlockState(pos).getBlock();
        if (block != this)
        {
            return block.getLightValue(world, pos);
        }
        return world.getBlockState(pos) == this.getDefaultState() ? offLight : onLight;
    }
    
    public void onBlockAdded(World worldIn, BlockPos pos, IBlockState state)
    {
        super.onBlockAdded(worldIn, pos, state);

    	worldIn.setBlockState(pos, this.blockState.getBaseState().withProperty(POWERED, worldIn.isBlockPowered(pos)));
    	
    	worldIn.markBlockForUpdate(pos);
    }

    /**
     * Called when a neighboring block changes.
     */
    public void onNeighborBlockChange(World worldIn, BlockPos pos, IBlockState state, Block neighborBlock)
    {
    	worldIn.setBlockState(pos, this.blockState.getBaseState().withProperty(POWERED, worldIn.isBlockPowered(pos)));
    
    	worldIn.markBlockForUpdate(pos);
    }
}

Still haven't figured this out. Is there a method in World to update lighting? I can't find it if it exists.
