I am interested in doing a gas for my mod (among other things) that is light sensitive and reaction depends on the light level itself, is there a means to which I can detect how much light it recieves? or any proximal block suffices

Both of them give me value 0 in broad daylight

This is the code I use to check it

 

	public boolean 	onBlockActivated(World world, int x, int y, int z, EntityPlayer player, int side, float hitX, float hitY, float hitZ){

	if (!world.isRemote){
		System.out.println("Light value: " + world.getBlockLightValue(x, y, z));
		System.out.println("Light_do true value: " + world.getBlockLightValue_do(x, y, z, true));
		System.out.println("Light_do false value: " + world.getBlockLightValue_do(x, y, z, false));
		System.out.println("saved light block: " + world.getSavedLightValue(EnumSkyBlock.Block, x, y, z));		
		System.out.println("saved light sky: " + world.getSavedLightValue(EnumSkyBlock.Sky, x, y, z));			
	}
	return true;

}

This is what I get

Light value: 0

Light_do true value: 0

Light_do false value: 0

saved light block: 0

saved light sky: 0
