How would i check if a certain block is in directly front of a Tile Entity? My Tile Entity is a generator and has a specific front? How would I go about checking if a block is in that direction?

 

Here's my code for looking for this block currently http://pastebin.com/hvDQhXK2

 

I want to make it so that machine[?] is only equal to that block if its not in front of the generator as I don't want to output power to it, if it is!

public EnumFacing getNearbyMachine(World world, BlockPos pos) {
   for (EnumFacing facing : EnumFacing.values) {
     TileEntity te = world.getTileEntity(pos.offset(facing, 1));
     if (te instanceof IEnergyAccepter) return facing;
  }
  return null;
}

Thank You
