[1.15] How to make lightning bold strike a character in front of me?

Hi I am a bit new in Minecraft. I want to make an axe that can spit lighting when I right click on my mouse. When I execute below code, I was hoping it would strike a cow that is front of my character, but all it did was produced the lightning sound, but I don't see any lightning anywhere. I thought my code, would produce a lighting 20 steps in front of me.

I think what I was missing in my code was a way to get a reference to the animal (cow) in front of me. I feel if I can get a reference of cow in front of me, I can set the my LightningBoltEntity to that animal position. But this is just a guess

public class AycLightningAxe extends AxeItem {
    public static final Logger LOGGER = LogManager.getLogger(AycFireballAxe.class);

    public AycLightningAxe() {
        super(ItemTier.IRON, 6.0F, -3.1F, new Item.Properties().group(ModItemGroup.MOD_ITEM_GROUP));
    }
    public AycLightningAxe(IItemTier tier, float attackDamageIn, float attackSpeedIn, Item.Properties builder) {
        super(tier, attackDamageIn, attackSpeedIn, builder);
    }

    public ActionResult<ItemStack> onItemRightClick(World world, PlayerEntity player, Hand handIn) {

        if (!world.isRemote) {
            Vec3d vec3d = player.getEyePosition(1.0F);
            Vec3d vec3d1 = player.getLook(1.0F);
            Vec3d vec3d2 = vec3d.add(20, 0, 0);
            BlockPos blockPos = new BlockPos(vec3d2);

            LightningBoltEntity lightning = new LightningBoltEntity(world, blockPos.getX(), blockPos.getY(), blockPos.getZ(), false);
            ItemStack itemStack = player.getHeldItem(handIn);
            itemStack.damageItem(1, player, (p_220040_1_) -> {
                p_220040_1_.sendBreakAnimation(handIn);
            });

            world.addEntity(lightning);
        }

        LOGGER.info("********** Abigail Lighting swing **************");
        return super.onItemRightClick(world, player, handIn);
    }
//AycLightningAxe

}

Any assistance would be greatly appreciated.
