Hi, I need help on Mixed Units tactics in python. Here is my code:

```python
# Practice using modulo to loop over an array

# Choose the mix and order of units you want to summon by populating this array:
summonTypes = ["soldier", "soldier", "soldier", "soldier", "archer", "archer", "archer", "archer"]
def summonTroops():
    # Use % to wrap around the summonTypes array based on len(self.built)
    #type = summonTypes[???]
    type = summonTypes[len(self.built) % len(summonTypes)]
def collectCoins():
    coin = hero.findNearest(hero.findEnemies())
    if coin:
        hero.move(coin.pos)
        
def commandTroops():
    friend = hero.findNearest(hero.findFriends())
    enemy = hero.findNearest(hero.findEnemies())
    if enemy and friend.type is not "palisade":
        if friend:
            hero.command(friend, "attack", enemy)
        
while True:
    summonTroops()
    collectCoins()
    commandTroops()

```

@Awsomedude1

In your **summonTroops** you should be actually summoning a troop.

use:  
hero.summon()

* * *
In your \*\*commandTroops\*\* I don't see a loop iterating through all of the troops to command them to attack. You only command the closest troop.

In your **summonTroops** you should either do something with the chosen type of unit or return it so that the other part of your code can do something with it.

Your **collectCoins** has some issues - have a close look at it.
