Is there still a way to check if a block has visibility to the sky[1.7.2]

[gmod622]

Pretty much a solar pannel, I need to be able to check if its day, and if it has visibility to the sky, I looked through the block class and did not find any thing interesting.

 

Thanks,

i would say take the blocks xyz pos, and see if there are any blocks on above the block on the y axis, from the blocks y pos to 256, i would also reccomend passing through glass and other transparent blocks. For example.

while(int y = yPos; y <=256; y++)
{
    if((world.getBlockatCoords(xPos,y,zPos) != null) || (world.getBlockatCoords(xPos,y,zPos) != Blocks.glass))
    {
         skyVisible = false;
    }
}

The method is getBlock(x, y, z) and the null check is useless. Blocks.air is returned in any case other than a regular block.

I use this for my solar furnace.

 

 public static boolean sunIsVisible = false;
    
    /**
     * Checks if the specified block is able to see the sky
     */
    public void updateSunVisibility()
    {
      this.sunIsVisible = isSunVisible(this.worldObj, this.xCoord, this.yCoord + 1, this.zCoord);
    }
    
    public static boolean isSunVisible(World world, int x, int y, int z)
    {
      return (world.isDaytime()) && (!world.provider.hasNoSky) && (world.canBlockSeeTheSky(x, y, z)) && (((world.getWorldChunkManager().getBiomeGenAt(x, z) instanceof BiomeGenDesert)) || ((!world.isRaining()) && (!world.isThundering())));
    }
