[Solved] [1.7.10] Different light levels per block?

[IceMetalPunk]

I'm trying to make a block that, depending on its metadata, can have any light level from 0 to 15. Since each of these blocks can have a different light level, I figure I need a tile entity. But how can I make the tile entity set the light level properly? I've tried using World#setLightValue(), but that doesn't seem to have any effect, even if I add a call to World#updateLightByType() after it. How can I make this work properly? (Also, do I even need a tile entity for this, or is there a more efficient way of handling it?)

 

Here's the tile entity's code:

 

package com.IceMetalPunk.weatherworks;

import net.minecraft.tileentity.TileEntity;
import net.minecraft.world.EnumSkyBlock;

public class TileEntitySunstone extends TileEntity {
private int metaData=0;
@Override
public void updateEntity() {
	if (this.worldObj.isRemote) { return; }
	int thisMeta=this.worldObj.getBlockMetadata(this.xCoord, this.yCoord, this.zCoord);
	if (thisMeta!=this.metaData) {
		this.worldObj.setLightValue(EnumSkyBlock.Block, this.xCoord, this.yCoord, this.zCoord, thisMeta);
		this.worldObj.markBlockRangeForRenderUpdate(this.xCoord-thisMeta, this.yCoord-thisMeta, this.zCoord-thisMeta, this.xCoord+thisMeta, this.yCoord+thisMeta, this.zCoord+thisMeta);
		this.worldObj.updateLightByType(EnumSkyBlock.Block, this.xCoord, this.yCoord, this.zCoord);
		this.metaData=thisMeta;
	}
}
}

You shouldn't need a TileEntity nor to set the light value, just use the method added by Forge that gives you the world and coordinates:

public int getLightValue(IBlockAccess world, int x, int y, int z) {
  int meta = world.getBlockMetadata(x, y, z);
  return value based on metadata;
}

>_< Of course it's that simple... I didn't even know that method existed. Sorry for my noobishness, but thank you for the help!
