The problem that I am facing is with dealing damage to Nalfar. I tried all the numbers from 0.1 through 0.8 for “z” in the reflect method, no use. I successfully reflect it towards him, but zero damage.

[Link to level](https://codecombat.com/play/level/reflective-shield?) (sub)  
Here is my code:

```python
# Use hero.reflect() to reflect back Nalfar's projectiles!

while True:
    enemy = hero.findNearestEnemy()
    missile = hero.findEnemyMissiles()[0]
    direction = Vector.normalize(Vector.subtract(enemy.pos, hero.pos))
    if missile and hero.distanceTo(missile) < 5:
        hero.reflect(Vector(direction.x, direction.y, 0.5))

```

okay … maybe you can try using Illia if you have her, because the level is made to use her reflect ability … and thanks for trying to help

Don’t need to find the nearest enemy. Find all missiles, it should return an array. Use a for loop to run through the missiles array and check is a missile exists before reflecting it. You don’t need to check the distance.

But what should I fill in the reflect?

That’s the code for now:

```python
while True:
    missiles = hero.findEnemyMissiles()
    for missile in missiles:
        if missile:
            hero.reflect(Vector(x, y, z))

```

</div>

```python
hero.reflect(Vector(direction.x, direction.y, 1.9))

```

It’s what you had except the z value is different.

</div>

It sends it too high. more than 0.8 is too high, less that 0.2 is too low, what’s in between hits Nalfar but does no damage

```python
while True:
    enemy = hero.findNearestEnemy()
    missiles = hero.findEnemyMissiles()
    direction = Vector.normalize(Vector.subtract(enemy.pos, hero.pos))
    for missile in missiles:
        if missile:
            hero.reflect(Vector(direction.x, direction.y, 1.9))

```

(nearest enemy is to find direction, which is for reflect, i dunno what else to do)

You have this already but you need to add this line of code right before the reflect statement:

```python
direction = Vector.subtract(missile.pos, hero.pos)

```

You don’t need to use enemy in your code, because enemy is irrelevant. For reflect reflect direction.x and direction.y and experiment with z values.

It worked, i didn’t need to change the z value from 1.9  
Thank you @abc
